     In addition, in the fraud detecting system, the control device has an artificial intelligence-utilizing or deep-learning structure capable of acquiring the position and the amount of gaming currency that is bet at each play position of the game table and extracting an abnormal situation by comparing a winning/losing history and an acquired amount of gaming currency for each player that are acquired from a result of winning/losing of each game with statistical data of past game. 
     Furthermore, in the fraud detecting system, the control device has an artificial intelligence-utilizing or deep-learning structure capable of extracting an abnormal situation by comparing a state in which the amount of the bet gaming currency at the time of losing is smaller than the amount of the bet gaming currency at the time of losing at a play position of a game table with statistical data of past games. 
     In addition, in the fraud detecting system, the control device has a structure capable of specifying whether the abnormal situation is extracted through the image analyzing device or an individual player at a play position at which winning of a predetermined amount of more is acquired. 
     Furthermore, in the fraud detecting system, the control device has a warning function for giving a notification of the presence of a specific player at another game table when the specified player leaves the seat and arrives at the another game table. 
     In order to solve the various problems described above, according to the present invention, a fraud detecting system in a game house including a plurality of game tables includes: a game recording device that records a state of progress of a game performed on each of the game table as a video including a dealer and a player through a camera; a card distributing device that determines a result of winning/losing of each game in the game table; an image analyzing device that performs an image analysis of the recorded video of the state of processing of the game; and a control device that can detect bills and gaming currency in the game table by using a result of the image analysis performed by the image analyzing device, and the image analyzing device or the control device has an artificial intelligence-utilizing or deep-learning structure capable of detecting exchange of bills and gaming currency in the game table in a situation other than in the middle of dealing cards based on information acquired from the card distributing device or the dealer, recognizing a total amount of genuine bills verified using among the bills and capable of recognizing a total amount of gaming currency also in a state in which a plurality of gaming currency come out onto the game table as an exchange target is in a state in which a part or the whole one is hidden due to a blind area of the camera and comparing a total amount of bills come out from the player onto the game table and a total amount of gaming currency come out from the dealer with each other and determining whether or not the both quantities match. 
     In addition, in the fraud detecting system, the control device has an artificial intelligence-utilizing or deep-learning structure capable of comparing/calculating whether or not the amount of gaming currency perceived in a dealer&#39;s tray for gaming currency in the game table is increased/decreased according to a payed amount of gaming currency corresponding to exchanged bills after a settlement through exchange of bills and gaming currency. 
     Furthermore, in the fraud detecting system, the control device has an artificial intelligence-utilizing or deep-learning structure capable of comparing/calculating match/mismatch of an input amount of bills according to a dealer&#39;s input and a total amount of bills according to a result of the image analysis performed by the image analyzing device after the settlement through exchange of bills and gaming currency. In addition, the control device has an artificial intelligence-utilizing or deep-learning structure capable of comparing/calculating match/mismatch of a total input amount of bills according to a dealer&#39;s input in the game table for which the dealer is responsible and a total amount of bills according to a result of the image analysis performed by the image analyzing device. 
     According to a fraud detecting system according to this embodiment, also when a card is bent according to player&#39;s squeeze of the card that is frequently performed in a Baccarat game or the like, the rank and the suit of the card can be determined through an image analysis, and a total amount of gaming currency disposed in the blind area or overlapping gaming currency can be perceived together with the position. In addition, fraud at the time of exchange of bills and gaming currency can be detected as well. 
     Hereinafter, an overview of the whole fraud detecting system in a game house including a plurality of game tables according to a first embodiment of the present invention will be described in more detail. 
       FIG.  1    is a diagram illustrating an overview of the whole system, the fraud detecting system in a game house including a plurality of game tables  4  includes: a game recording device  11  that records the state of progress of a game performed in the game table  4  as a video including players  6  and a dealer  5  through a plurality of camera devices  2 ; an image analyzing device  12  that performs an image analysis of the recorded video of the state of process of the game; and a card distributing device  3  that determines and displays a result of winning/losing of each game in the game table  4 . The card distributing device  3  is a so-called electronic shooter that has already been used by persons skilled in the art and has rules of a game programmed in advance and has a structure capable of determining winning/losing of a game by reading information of distributed cards C. For example, in a Baccarat game, winning of the baker, winning of a player, or tie (drawn) is determined basically based on the ranks of two to three cards, and a determination result (a result of winning/losing) is displayed in a result display lamp  13 . 
     The fraud detecting system further includes a control device  14  that compares the rank of actual cards according to a result of the image analysis performed by the image analyzing device  12  and a result of winning/losing determined by the card distributing device  3  with each other and detects fraud (mismatch between a sum of ranks of distributed cards and a result of winning/losing) performed in the game table  4 . The card distributing device  3  has a structure capable of reading ranks (A, 2 to 10, J, Q, K) and suits (hearts, spades, or the like) of cards C that are manually distributed by the dealer  5 , and the control device  14  has a structure capable of determining match/mismatch by collating information of a rank and suites acquired by the image analyzing device  12  (using artificial intelligence) from a video (captured by using the camera device  2 ) of cards distributed in the game table  4  and information of cards and suits read by the card distributing device  3  with each other. The image analyzing device  12  and the control device  14  of the fraud detecting system have a structure integrally including a computer formed as one body or by a plurality of configurations, a program, and a memory. 
     The image analyzing device  12  and the control device  14  have an artificial intelligence-utilizing or deep-learning structure capable of acquiring information of ranks of cards also for cards C that are distributed in the game table  4  and are bent or contaminated by the player  6 . For a contaminated card C, as illustrated in  FIG.  3   , there is a situation in which it is difficult to determine clubs or spades. Also in such a case, the suite can be determined by an artificial intelligence-utilizing computer or control system, an analysis and a determination of an image using a deep learning (structure) technology. In addition, also in a case where a card is bent according to a player&#39;s squeeze of a card, which is frequently performed in a Baccarat game or the like, by using self-learning of examples of many deformations of images or the like, a suit and a rank of a card before deformation can be recognized according to an artificial intelligence-utilizing computer or control system and a deep learning (structure) technology. The artificial intelligence-utilizing computer or control system and the deep learning (structure) technology are known as a person skilled in the art and can be used, and thus, detailed description thereof will not be presented. 
     The control device  14  having an artificial intelligence-utilizing or deep learning structure can perceive a position (a player, a banker, or a pair) inside a bet area  8  on which each player  6  bets gaming currency  120 , the type (a value of a different amount is assigned to gaming currency  120  for each color) of the bet gaming currency  120  through the camera device  2  and the image analyzing device  12 . Not only there is a case where the gaming currency  120  is vertically arranged to be superimposed but also there is a case where the gaming currency is superimposed with deviations as illustrated in  FIG.  2 A . In such a case, in a case where the camera device  2  is positioned in the direction of an arrow X illustrated in  FIG.  2 A  (or the direction of the gaming currency  120  is relatively in a blind area), as illustrated in  FIG.  2 B , it is assumed that the gaming currency  120  is not visible (enters a blind area). According to the artificial intelligence-utilizing computer or control system or the deep-learning technology, by using a self-learning function or the like, hidden gaming currency  120  due to a blind area or the like is recognized (there are case where a part of one unit of gaming currency is hidden or a case where the whole gaming currency is hidden), and the number of quantity and the like can be correctly perceived. 
     In this way, since a position (a player, a banker, or a pair) inside the bet area  8  on which the gaming currency  120  is bet and the type (a value of a different amount is assigned to gaming currency  120  for each color) and the quantity of the bet gaming currency  120  can be perceived, the control device  14  determines whether or not collection (denoted by an arrow L) of the losing gaming currency bet by each player  6  and payment ( 120 W) for winning gaming currency to a player  6 W who has won are properly performed according to a result of winning/losing of a game in accordance with a result of winning/losing of the game determined by the card distributing device  3  in each game by analyzing a video of the state of process of the game through the image analyzing device  12 . In a case where a determination result acquired through an analysis using the image analyzing device  12  is different from a result (for example, a result of reading using an RFID) of reading using the other means, the intelligent-type control device  14  stores the analysis image and can verify the result later. As a result of the verification, in the case of an error in the intelligent-type control device  14 , by using the analysis image as sample data of teacher leaning in the deep-learning technology, the accuracy of the intelligent-type control device  14  can be improved. 
     The control device  14  can analyze and acquire a total amount of the gaming currency  120  in the tray  17  for gaming currency for the dealer  5  in the game table  4  by using the image analyzing device  12  and can compare and calculate whether or not a total amount of the gaming currency  120  inside the tray  17  for the gaming currency  120  has been increased or decreased according to the amount of collection of the losing gaming currency  120  bet by each player  6  and the amount of the payment  120 W for winning gaming currency to a player  6 W who has won after the end of the game and the settlement based on a result of winning/losing of the game. A total amount of the gaming currency  120  in the tray  17  for gaming currency  120  may be constantly acquired using means such as an RFID, and the control device  14  determines whether or not the increased/decreased amount is correct by analyzing the video of the state of progress of the game through the image analyzing device  12 . 
     For this, the artificial intelligence-type or deep-leaning structure is also used. 
     In this example, since fraud or a mistake is detected based on a result of winning/losing of a game, information of the type of bet gaming currency  120 , the position (a player, a banker, or a pair) inside the bet area  8  on which the gaming currency  120  is bet, and the quantity of the gaming currency  120 , and an increased/decreased amount of the gaming currency  120  in the tray  17  for gaming currency after the end of the collection of losing gaming currency and the repayment for the won gaming currency  120  without acquiring the movement of the gaming currency  120  after the end of the game, that is, whether the bet gaming currency  120  has been moved to the player side or the dealer side. 
     For example, in the case of Baccarat, a result of winning/losing of a game can be determined based on rules of Baccarat by reading ranks of cards C delivered in that game by the card distributing device  3 . In addition, a result of winning/losing of a game can be determined also by imaging an area on the game table  4  by using the camera device  2 , analyzing the image using the image analyzing device  12 , and collating a result of the analysis with the rules of the game by using the control device  14 . In such a case, a winning/losing result determining device is configured by the camera device  2 , the image analyzing device  12 , and the control device  14 . The information of a player of each play position  7 , the type of bet gaming currency  120 , the position (a player, a banker, or a pair) inside the bet area  8  on which the gaming currency  120  is bet, and the quantity of the gaming currency  120  is acquired by imaging the gaming currency  120  placed on the bet area  8  by using the camera device  2  and analyzing the image for each play position  7  by using the image analyzing device  12 . 
     In addition, an increased/decreased amount of gaming currency  120  in the tray  17  for gaming currency before and after the collection of losing gaming currency  120  and the repayment for winning gaming currency  120  can be calculated by comparing a total amount of the gaming currency  120  disposed inside the tray  17  for gaming currency before the collection of losing gaming currency  120  and the repayment for won gaming currency  120  with a total amount of the gaming currency  120  disposed inside the tray  17  for gaming currency after the collection of losing gaming currency  120  and the repayment for won gaming currency  120 . 
     The total amount of the gaming currency  120  disposed inside the tray  17  for gaming currency before the collection of losing gaming currency  120  and the repayment for won gaming currency  120  and the total amount of the gaming currency  120  disposed inside the tray  17  for gaming currency after the collection of losing gaming currency  120  and the repayment for won gaming currency  120  can be detected by imaging the tray  17  for gaming currency housing the gaming currency  120  using the camera device  2  and analyzing the image using the image analyzing device  12 . In addition, by embedding an RFID representing the amount inside gaming currency  120  and arranging an RFID reader in the tray  17  for gaming currency, a total amount of the gaming currency  120  housed in the tray  17  for gaming currency may be configured to be detected. 
     For example, it is assumed that the total amount of the gaming currency  120  disposed on the tray  17  for gaming currency before the start of a game is Bb, and the total amount of the gaming currency  120  disposed on the tray  17  for gaming currency after the game ends, and the collection of losing gaming currency  120  and the re-payment for winning gaming currency  120  is Ba. In addition, in this game, a total amount of all the play positions  7  of gaming currency  120  that is bet on the player area is bp, a total amount of all the play positions  7  of gaming currency  120  that is bet on the banker area is bb, and a total amount of all the play positions  7  of gaming currency  120  that is bet on a tie area is bt. For example, in a case where a result of winning/losing of a game is the winning of the banker, Ba−Bb=bp−bb+bt needs to be satisfied. Alternatively, the total amount Ba of the gaming currency  120  of the tray  17  for gaming currency after the end of the game needs to be (Bb+bp−bb+bt). Otherwise, it can be determined that there is fraud or a mistake in the collection or repayment of the gaming currency. 
       FIG.  13 A  is a diagram illustrating details of a tray for gaming currency according to this embodiment, and  FIG.  13 B  is a diagram illustrating another example of a tray for gaming currency. In the tray  17  for gaming currency, a collection tray  171  for gaming currency that is used for collecting and temporarily storing gaming currency  120 L for gaming that is bet by a losing player  6 L and a repayment tray  172  for gaming currency  120 W for gaming that is used for storing gaming currency  120 L for gaming to be re-payed are arranged. The image analyzing device  12  and the control device  14  acquire the position, the type, and the quantity of gaming currency  120 L for gaming that is bet by the losing player  6 L and calculates an increased amount (an amount of gaming currency  120  to be present in the collection tray  171  for gaming currency) of gaming currency  0 L for gaming in the game. In addition, the image analyzing device  12  and the control device  14  acquires a real total amount of gaming currency  120  in the tray  171  for gaming currency after the collection and compare a total amount with the real total amount to determine whether or not there is a difference therebetween. 
     In addition, for the repayment of gaming currency  120 W for gaming for a winning player  6 W, by using gaming currency  120  that is present in the repayment tray  172  for gaming currency, a sufficient time can be secured for the image analyzing device  12  and the control device  14  to acquire a real total amount of gaming currency  120  in the collection tray  171  for gaming currency after collection. 
     As illustrated in  FIG.  1   , the game table  4  includes a disposal area  41  and/or a disposal slot  42  used for disposing cards C used in a game. When a game ends, the cards C used in the game are collected and are put into the disposal area  41  or the disposal slot  42  on the game table  4 . 
     The game table  4  further includes a marker  43  representing winning/losing of a game. 
       FIG.  4 A  is a plan view illustrating the front side of a marker, and  FIG.  4 B  is a plan view illustrating the back side of a marker. In a Baccarat game, two types of a marker  43   a  representing the winning of the player and a marker  43   b  representing the winning of the banker are used, and, when a result of a game comes out, the dealer  5  overturns the marker of the winning side out of the player or the banker. In this way, winning/losing of a game is represented on the table to be easily understood. The overturned marker is returned to the original state by the dealer  5  after the collection and the repayment of gaming currency  120 . By returning the marker to the original state, it also represents a state in which a next game can be started. 
     As above, in this embodiment, the control device  14  calculates the amount of bet gaming currency on the game table  4  and a balance of gaming currency from a result of winning/losing of a game for each game and verifies an increased amount of the balance of gaming currency inside the tray  17  for gaming currency after the game. When a difference is detected in this verification, the control device  14  generates an alarm or adds recording of an indication thereof in the recording of a video captured by the camera device  2 . A casino operator can peruse the reason for the difference by checking the video. 
     The fraud detecting system according to this embodiment adds/subtracts an increased/decreased amount of gaming currency in a game calculated based on the positions, the types, and the quantities of gaming currency  120  that is bet by all the players  6  in the game and a result of winning/losing of the game acquired by the winning/losing result determining device to/from a total amount of gaming currency  120  in the tray  17  for gaming currency before a settlement of each game, compares a total amount of gaming currency  120  to be present in the tray  17  for gaming currency after the settlement at the time of the end of the game with a real total amount of gaming currency  120  in the tray  17  for gaming currency at the time of end of the game that is acquired through the image analyzing device  12 , and determines whether or not there is a difference between a total amount and a real total amount. 
     The control device  14  acquires the position, the type, and the quantity of gaming currency that is bet by each player through the image analyzing device  12 , acquires a real total amount of gaming currency placed in the tray for gaming currency when all the collections of losing gaming currency bet by each player end, compares a total amount of gaming currency  120  to be present in the tray  17  for gaming currency, which is acquired by adding an increased amount in the tray  17  for gaming currency in the game based on the positions, the types, and the quantities of gaming currency bet by losing players to a total amount of gaming currency placed in the tray for gaming currency before a settlement of each game, with a real total amount of gaming currency  120  placed in the tray  17  for gaming currency, and determines whether or not there is a difference between the total amount and the real total amount. 
     In a case where the control device  14  compares a total amount of gaming currency  120  to be present in the tray  17  for gaming currency, which is acquired by adding an increased amount in the tray  17  for gaming currency in the game based on the positions, the types, and the quantities of gaming currency  120  bet by losing players to a total amount of gaming currency  120  placed in the tray  17  for gaming currency before a settlement of each game, with a real total amount of the gaming currency  120  placed in the tray  17  for gaming currency, and determines that there is no difference between the total amount and the real total amount, and compares a total amount to be present in the tray  17  for gaming currency after the settlement at the time of end of the game with a real total amount of gaming currency  120  placed in the tray  17  for gaming currency at the time of end of the game acquired through the image analyzing device  12 , and determines that there is a difference between the total amount and the real total amount, the control device  14  determines a mistake in the payment and generates a payment error signal used for giving a notification of the mistake in the payment. 
     In the tray  17  for gaming currency, the collection tray  171  for gaming currency that collects and temporarily stores gaming currency  120  bet by losing players is arranged, and the image analyzing device  12  compares a total amount of gaming currency  120  to be present in the collection tray  171  for gaming currency, which is acquired by adding an increased amount of gaming currency  120  in the game that is calculated based on the positions, the types, and the quantities of the gaming currency  120 L for gaming bet by losing players, with a real total amount of the gaming currency  120  placed in the tray  171  for gaming currency, and determines whether or not there is a difference between the total amount and the real total amount. 
     When the control device  14  determines a difference in the real total amount of the gaming currency  120  acquired from the tray  17  for gaming currency for the dealer  5  of the game table  4  not corresponding to the increased/decreased amount of the gaming currency calculated based on the amount of gaming currency bet by all the players and a result of winning/losing of the game, the game recording device  11  assigns an index or time to the acquired video or can reproduced with a collection scene or a payment scene of the gaming currency  120  specified such that the recording of the game in which the difference occurs can be analyzed by the game recording device  11 . 
     In this way, the control device  14  acquires a total amount of gaming currency (chips) placed in the tray  17  for gaming currency after a settlement at the time of end of a game through the image analyzing device  12 . In this case, the determination of “after the settlement” is when one of “1)” to 4)” occurs: 1) when repayment for won gaming currency  120  (won chips) ends; 2) when cards C used in the game are collected and are disposed in the disposal area or the disposal slot of the table; 3) when a predetermined button accompanying the winning/losing result determining device is pressed; 4) when the marker  43  representing winning/losing is returned to the original state. 
     In the management system of the table game, the management control device images the positions, the types, and the quantities of gaming currency that is placed by game participants in each game when any one of 1) to 3) is detected: 1) when the card distributing device detects that a first card is drawn; 2) before and after drawing; 3) after the management control device recognizes a dealer&#39;s bet end sign. 
     In addition, the control device  14  has an artificial intelligence-utilizing or deep-learning structure capable of acquiring the position (a position for betting on the player, the banker, or the fair) and the amount (the types and quantities) of bet gaming currency at each player position  7  of the game table  4 , comparing a winning/losing history of each player  6  and the amount (won amount) of acquired gaming currency that can be acquired based on the result of winning/losing of each game with statistical data of many (big data) games in the past, and extracting an abnormal situation (set in the casino). 
     Typically, the control device  14  is included which has an artificial intelligence-utilizing or deep-learning structure capable of extracting an occurrence of a won amount of a certain amount (one million dollars) or more and an abnormal situation in which, in a play position  7  of a specific game table  4 , a state in which the amount of bet gaming currency is small at the time of losing a game, and the amount of bet gaming currency is large at the time of winning a game is continued for several games and is determined as an abnormal situation based on a comparison with statistical data (big data or the like) of games in the past. 
     In addition, the control device  14  (integrated with the image analyzing device  12 ) of the fraud detecting system has a structure capable of extracting an abnormal situation or specifying an individual player  6  at the play position  7  at which winning of a predetermined amount of more is acquired. In such specifying of a player  6 , the image of each face is specified with a profit and an identify number (an ID or the like) assigned thereto in the image analyzing device  12 . Then, the control device  14  has a warning function for giving a notification of the presence of a specific player in another game table when the specified player  6  leaves a seat and arrives at the another game table. More specifically, a notice is given to a pit manager managing each game table  4  or each table staff (or a dealer), wherein further prevention of an abnormal phenomenon is achieved. 
     The control device  14  includes a database recording a history of exchange of bills K and gaming currency  120 , refers to the database at the interval of a predetermined time or in units of one day and determines through a comparison whether or not the amount of gaming currency  120  acquired in the tray  17  for gaming currency for the dealer  5  of the game table  4  has been increased or decreased according to a payed amount of gaming currency  120  corresponding to exchanged bills K or a total amount of payment of bills K corresponding to exchanged gaming currency  120 . 
     In addition, a winning/losing history of each play position  7  and the amount (won amount) of acquired gaming currency may be monitored without specifying an individual player  6 . 
     In such a case, while, in a case where each player  6  leaves the seat, the player  6  cannot be tracked, an abnormal situation such as a case where, a state in which the amount of bet gaming currency is small at the time of losing a game at a specific play position  7  of one game table  4 , and the amount of bet gaming currency at the time of winning a game is large is continued for several games or the like can be detected. Then, in a case where such a play position  7  is detected, there is a suspicion that there is fraud or a mistake at the play position  7 . Then, by verifying a video in which the play position  7  is imaged, a fraud or a mistake can be found. 
     More specifically, the camera device  2  is mounted to image at least gaming currency  120  placed in the bet area  8  of the game table  4 . The image analyzing device  12  analyzes images captured by the camera device  2  and detects a position among the positions of the player, the banker, and the tie of the bet area  8  at which gaming currency is placed for each user position  7  and the amount of the placed gaming currency. In addition, the card distributing device  3  also functions as a winning/losing result determining device and determines a result of winning/losing of a game. The control device  14 , based on the position (the player, the banker, or the tie) inside the bet area  8  at which the gaming currency  120  is placed and the result of winning/losing of the game, records monitors) a winning/losing history for each play position  7  and the amount (an acquired amount of the gaming currency) of the gaming currency that has been acquired. Here, any one of the winning/losing history and the acquired amount of the gaming currency may be recorded. In a case where the winning/losing history/or the acquired amount of the gaming currency is in an abnormal situation (set in the casino) when compared with the statistical data of many (big data) games in the past, the control device  14  specifies this player position  7  as a play position at which a suspicion of fraud is present. 
     In a case where there is a suspicion of fraud for a specific player position  7 , the fraud detecting system may be configured to generate an alarm (light, a sound, or a vibration) such that at least the dealer gets near at the time point. In this way, a game thereafter is stopped at least at the place or the like, and the continuation of fraud can be blocked. In addition, information representing a suspicion of fraud may be added to a video that is captured and recorded by the camera device  2 . Accordingly, by checking the video, the cause of the suspicion of fraud can be investigated. 
     The fraud detecting system in a game house including a game table according to this embodiment further has a function of performing an inspection at the time of exchange of bills and gaming currency that is frequently performed in the game table  4 . In a game house such as a casino, before a game, a player  6  exchanges bills (cash or the like) and gaming currency at a predetermined gaming currency clearing house. However, when all the gaming currency is used, the player  6  can continue the game by exchanging cash (bills) with gaming currency  120  on the game table (a Baccarat table or the like) without leaving the seat from the game table  4 . However, here, there is a chance for fraud between the dealer  5  and the player. The exchange of cash (bills) for gaming currency  120  on a game table (for example, a Baccarat table or the like) needs to be performed when a game does not advance. In order to determine winning/losing of a game, the card distributing device  3  can detect the start of dealing of cards and the end of dealing (a time period for determining winning/losing). For this reason, the card distributing device  3  detects a situation other than the distribution (dealing) of cards, and the control device  14  detects exchange of bills and gaming currency  120  on the game table  4  in a situation other than the dealing of cards (illustrated in  FIG.  5   ). 
     Being in the middle of the dealing (or any other situation) of cards can be detected based on information acquired from the operation of the card distributing device  3  or the dealer  5 . 
     The control device  14  can recognize the quantity and the amount of bills by performing an image analysis of the surfaces of the bills K. In addition, in the game table  4 , it is determined whether or not bills K to be exchanged for gaming currency  120  are genuine by detecting genuine marks G of the bills by emitting black light. As illustrated in  FIG.  5   , the control device  14  has an artificial intelligence-utilizing or deep-learning structure verifying the genuine marks G through an image analysis, recognizing a total amount of genuine bills, being capable of recognizing a total amount of gaming currency even in a state in which a plurality of gaming currency come out onto the game table as an exchange target is hidden due to a blind area of the camera device  2 , comparing a total amount of the bills K come out onto the game table  4  from a player with a total amount of the gaming currency  120  come out from the dealer  5 , and being capable of determining whether or not both the amounts match each other. 
     The control device  14  has an artificial intelligence-utilizing or deep-leaning structure capable of determining whether or not a total amount of gaming currency  120  placed in the tray  17  for gaming currency for the dealer  5  of the game table  4  has been increased/decreased according to a paid amount of gaming currency corresponding to the exchanged bills after a settlement through exchange of the bills and the gaming currency. A case may be considered as well in which the total amount of the gaming currency  120  placed in the tray  17  for gaming currency for the dealer  5  is constantly acquired in advance by using RFIDs of gaming currency  120  or the like. In addition, the total amount of the gaming currency  120  housed in the tray  17  for gaming currency can be detected by imaging the tray  17  for gaming currency housing the gaming currency  120  by using the camera device  2  and analyzing the image using the image analyzing device  12 . 
     In addition, the control device  14  detects whether an increase/decrease in the amount of the gaming currency  120  present inside the tray  17  for gaming currency before and after the exchange of bills and the gaming currency matches an exchange amount of the gaming currency as a result of an image analysis on the game table  4 . The amount of paid bills may be input by the dealer  5  to the control device  14  through key input or the like or may be specified by imaging an area disposed on the game table  4  in which bills are paid by using the camera device  2  and analyzing the image using the image analyzing device  12 . 
     As described above, the control device  14  determines whether or not a decreased amount of the gaming currency  120  from the tray  17  for gaming currency according to the exchange of bills and the gaming currency matches the amount paid to the dealer  5  from players  6 . In addition, the control device  14  is an intelligence-type control device capable of determining match/mismatch of an input amount (commonly, according to key input or the like) of bills input by the dealer  5  and a calculated amount of bills that is a result of an image analysis performed by the image analyzing device  12  after the settlement through the exchange of the bills and the gaming currency through a comparison and calculation and may have an artificial intelligence-utilizing or deep-learning structure. 
     Furthermore, the control device  14  has an artificial intelligence-utilizing or deep-learning structure capable of determining match/mismatch of a total amount of bills according to the input of a dealer in the game table  4  for which the dealer is responsible and a total amount of bills according to a result of an image analysis using the image analyzing device  12  through a comparison and calculation. 
     The control device  14  determines whether or not the amount of gaming currency  120  perceived in the tray  17  for gaming currency for the dealer  5  of the game table  4  has increased/decreased according to a paid amount of gaming currency  120  corresponding to exchanged bills after the exchange of the bills and the gaming currency  120  or a paid amount of bills corresponding to the exchanged gaming currency  120  through a comparison. 
     The control device  14  is a control device having an artificial intelligence-utilizing or deep-learning structure capable of acquiring information of the types and the quantities of the gaming currency  120  even in a state in which a part of or the whole one unit of gaming currency is hidden when the types and the quantities of the gaming currency  120  are determined. 
     A management system according to a second embodiment relates to a management system of table games in a game house. 
     In a game house such as a casino, there are various attempts preventing dealer&#39;s mistakes in handling gaming currency (gaming currency). A game house includes monitoring cameras used for monitoring dealer&#39;s mistakes in handling gaming currency, and such mistakes are prevented using a determination of mistakes and fraud according to collection and repayment of gaming currency that are different from a result of winning/losing based on images acquired using the monitoring cameras and the like. 
     Meanwhile, in order to acquire the quantity and a total amount of gaming currency, it has been proposed to acquire the amount of the gaming currency by attaching an IC tag to each gaming currency. 
     In a card game monitoring system disclosed in Int&#39;l App. No. PCT/JP2015/000171, it is determined whether or not gaming currency place on a game table is collected or re-payed according to a result of winning/losing by performing an image analysis of movement of the gaming currency, and monitoring of dealer&#39;s mistakes in handling the gaming currency is performed. 
     In game houses such as casinos, while gaming currency is piled to have a high volume and is placed on a game table, there is a problem in that a total amount cannot be correctly read by a reading device for IC tags disposed under the game table, and, when the sensitivity of the reading device is increased, gaming currency or gaming placed at a different position (winning/losing depends on the position) is added, and there is a problem in that a total amount of gaming currency at each position cannot be perceived. In addition, conventionally, as illustrated in  FIG.  7   , the pattern of gaming currency (gaming currency)  9  is complicated, and, when a plurality of gaming currency are piled, there is a problem in that the quantity of such a pile cannot be accurately acquired using a camera. 
     Furthermore, fraud on a game table has been advanced, and there is a new problem in that fraud using an advanced betting method or the like that cannot be found in simple detection of a large winning amount on a game table or the like cannot be found by using a camera. 
     In addition, it is necessary for a dealer to collect or re-paid gaming currency placed on a game table according to a result of winning/losing. In a case this is to be determined by performing an image analysis of the gaming currency, since the pattern of the gaming currency (gaming currency) is complicated, there is a problem in that it cannot be determined whether or not a dealer correctly performs re-payment when gaming currency corresponding to the bet gaming currency is re-payed by using a currently-existing practical image analyzing technology, and the prevention of mistakes is not sufficient. 
     In order to solve the various problems described above, a management system of table games according to this embodiment includes: a card distributing device that determines and displays a result of winning/losing of each game in a game table; a measurement device that measures the types and the quantities of gaming currency place on the game table by using a camera; and a management control device that specifies and stores the position, the types, and the quantity of gaming currency placed on the game table by a game participant by using a result of the measurement performed by the measurement device in each game. The gaming currency has a configuration in which a plurality of plastic layers of different colors are stacked, at least a coloring layer is included in the middle, and a stripe pattern in a stacking direction is formed on a side face by employing a multi-layer structure in which white layers or thin-color layers are stacked on both sides of the coloring layer disposed in the middle, and the type of the gaming currency can be specified by using the coloring layer. The management control device has calculation functions of determining a winner and a loser among participants in each game by using a result of winning/losing acquired from the card distributing device and a result of the measurement of the position, the types, and the quantities of the gaming currency placed by each game participant and calculating the balance of the casino side in the game table for each game. 
     In addition, in the management system, the management control device has a structure including a function of determining the quantity of the gaming currency by measuring the number of coloring layers, the white layers, or the thin-color layers of the gaming currency placed by each game participant. 
     In order to solve the various problems, gaming currency according to this embodiment has a configuration in which a plurality of plastic layers of different colors are stacked, at least a coloring layer is included in the middle, and a stripe pattern in a stacking direction is formed on a side face by stacking white layers or thin-color layers on both sides of the coloring layer, and the type of the gaming currency can be specified by using the coloring layer. 
     In addition, in the gaming currency, on the surface of the white layer or the thin-color layer, a print representing the type of the gaming currency is formed, transparent layers are disposed in outermost layers, and each interlayer is thermos-compressed to form a structure of at least five layers. 
     In addition, in the gaming currency, marks using UV ink or ink (carbon black ink) absorbing infrared rays are arranged on the surfaces of the white-color layers or the thin-color layers, or embossing processing is performed for the transparent layer of the outermost layer, or R processing is performed for the ends of the transparent layers of the outermost layers, or the coloring layer is formed by a plurality of layers, and RFIDs may be built in the coloring layers. 
     In order to solve the various problems described above, an inspection device inspecting gaming currency according to this embodiment includes: a passage including an inlet and an output through which the gaming currency can pass in a radial direction; a gaming currency type determining device that determines a color of the stripe in the staking direction of the side face by imaging the side face of the gaming currency passing through the passage; a mark reading device that reads a mark, which is formed using the UV ink or the ink (carbon black ink) absorbing infrared rays, arranged on the surface of the passing gaming currency; a print inspecting device that reads a print representing the type arranged on the surface of the gaming currency in a vertical direction with respect to the passage; and a control device of the whole device. The control device is configured to inspect whether or not the type of the gaming currency determined by the gaming currency type determining device matches a content of the print representing the type acquired by the print inspecting device. 
     According to the system of this embodiment, even in a case where many gaming currencies (gaming currency) are piled up, the quantity of the gaming currencies can be determined, and a total amount of relatively overlapping gaming currency can be acquired based on the position and the color. 
     Hereinafter, a management system of table games in a game house including a game table according to an embodiment of the present invention will be described.  FIG.  6    is a diagram that illustrates an overview of the whole system. The management system of table games in a game house including a plurality of game tables  4  includes: a measurement device  19  including an image analyzing device  18  that records a state of process of a game played in the game table  4  as a video including game participants  6  and a dealer  5  through a plurality of camera devices  2  and performs an image analysis of the recorded video of the state of process of the game; and a card distributing device  3  that determines and displays a result of winning/losing of each game in the game table  4 . The card distributing device  3  is a so-called electronic shooter that has already been used by persons skilled in the art and has rules of a game programmed in advance and has a structure capable of determining winning/losing of a game by reading information of distributed cards C. For example, in a Baccarat game, winning of the baker, winning of a player, or tie (drawn) is determined basically based on the ranks of two to three cards, and a determination result (a result of winning/losing) is displayed in a result display lamp  13 . 
     The management control device  14  reads information (ranks and suits) of cards C acquired from the card distributing device  3  and determines a result of winning/losing of each game and determines a winner  6 W and a loser  6 L among the participants  6  in each game by using a result of measurement of the position, the types, and the quantities of gaming currency  120  placed by the game participants  6 . 
     In addition, the management control device  14  has a calculation function of calculating a balance (an amount acquired by subtracting a total amount of gaming currency  120  that is re-paid to a winner  6 W among the participants  6  from a total amount of gaming currency  120  bet by the loser  6 L) of the casino side in the game table  1  for each game. 
     The image analyzing device  18 , the measurement device  19 , and the management control device  14  of this detection system have a structure integrally including a computer formed as one body or by a plurality of configurations, a program, and a memory. 
     Next, details of gaming currency used in this detection system will be described.  FIG.  8    is a front cross-sectional view of gaming currency  120  used in this detection system. The gaming currency  120  has a multi-layer structure in which a plurality of plastic layers having different colors are stacked, a coloring layer  121  is included at least in the middle, and white layers  122  or thin-color layers (while not illustrated in the drawing, the layers may be layers of a color that is thinner than that of the coloring layer  121 ) are stacked on both sides of the coloring layer  121  of the middle. 
     In this way, by employing a multi-layer structure in which the coloring layer  121  is included, and white layers  122  or thin-color layers (while not illustrated in the drawing, the layers may be layers of a color that is thinner than that of the coloring layer  121 ) are stacked on both sides of the coloring layer  121  of this middle, as illustrated in  FIG.  9 A , a stripe pattern is formed on the side face in the stacking direction, and the type of the gaming currency  120  can be specified by changing the color (red, green, yellow, blue, or the like) of the coloring layer  121  for each type (10 points, 20 points, 100 points, 1000 points, and the like) of the gaming currency  120 . 
     The gaming currency  120  is configured as a structure body including the coloring layer  121  and the white layer  122  or the thin-color layer at least in the outer appearance to form a stripe pattern in the axial direction on the side face and has a configuration enabling the type of the gaming currency  120  to be specified using the coloring layer  121 . While  FIGS.  10 A and  10 B  illustrate different examples, in the examples, the coloring layer  121  and the white layer  122  or the thin-color layer are formed through injection molding, and so-called two-color molding is used in which, first, the coloring layer  121  is molded inside a die for molding (not illustrated in the drawing), and thereafter, the white layer  122  or the thin-color layer is molded. 
     In addition, as illustrated in  FIG.  9 B , in the gaming currency  120 , prints  123  (100 points or the like) representing the type of the gaming currency  120  are formed on the surfaces (the upper face and the lower face) of the white layer  122 . As illustrated in  FIG.  8   , the transparent layers  124  are disposed in the outermost layers, and each interlayer is thermos-compressed, and a structure of at least five layers is formed. Such gaming currency  120  is formed by using a plastic material having a thin long shape, and layers (the coloring layer  121 , the white layer  122 , and the transparent layer  124 ) are thermo-compressed to form a closely adhering state (a structure of five layers or the like) in the state of a long length, and thereafter, holes having a circular shape, a rectangular shape, or the like are formed therein through press or the like. 
     When a hole is formed through the press, die of mold for punching, and the size of punching are designed, and R processing (round angle) is performed for the ends of the transparent layer  124  of the outermost layer. 
     That is, in order to manufacture the gaming currency  120 , first, a plate-shaped coloring layer  121  formed using plastic and a plate shaped white layer  122  or a thin-color layer formed using plastic are stacked, and a stacked structure body configured by a plurality of plastic layers is formed. Then, drawing patterns are printed on the upper face and the lower face of this stacked structure body, and transparent layers  124  are formed thereon. Then, the layers of the stacked structure body and the transparent layers  124  are heated and pressed to be heated and welded, whereby a gaming currency original plate is generated. Then, punching processing is performed for the gaming currency original plate acquired in this way, whereby a plurality of gaming currencies  120  having a predetermined shape are acquired. When this punching processing is performed, R processing is performed for upper and lower angles of the gaming currency  120  using a mold. 
     In addition, in the gaming currency  120 , face codes using the UV ink or ink (carbon black ink) absorbing an infrared rays are arranged on the surface of the white layer  122  (see  FIG.  9 B ). This face codes represent the authenticity of the gaming currency  120 , and, when ultraviolet rays (or infrared rays) are emitted thereto, a mark is visible to the eyes, and a combination of the form and the number of the marks represents the authenticity.  FIG.  11    is a perspective view of a state in which the gaming currency  120  is stacked up, and a face code M is acquired by combining a long code L and a short code S. In the outermost layers, while transparent layers (print layers)  124  are thermally compressed or formed as coating layers to cover the print  123  and the face code, embossing processing is performed for these transparent layers  124 , and the close adherence between the gaming currencies  120  is prevented. In addition, in this embodiment, while an example has been described in which face codes are printed on the surfaces of the white layers  122 , instead of the face codes or together with the face codes, one or both of a security mark and an optically variable device (OVD) may be printed. 
     The R processing (R) is performed for the ends of the transparent layers (print layer)  124  of the outermost layer for which the print  123  (100 points or the like), and in the punching process of the gaming currency  120 , the surfaces of the white layers  122  are prevented from being deformed to appear on the side face. In addition, it is prevented that a sharp end remains in the gaming currency  120  and damages the hands or the other gaming currency  120 . 
     The coloring layer  121 , as illustrated in  FIG.  8   , may be formed by a plurality of colored layers (three layers in the case illustrated in  FIG.  8   ). Since the plurality of colored layers (three layers in the case illustrated in  FIG.  8   ) are thermos-compressed, a state in which the three-layer structure can be visually observed, as illustrated in  FIG.  8   , is not formed. However, three layers are illustrated in  FIG.  8    for description. In addition, in a middle layer among the three layers of the coloring layer  121 , a partly hollowed portion B is arranged, and an RFID  125  is built therein. 
     In addition, without arranging the hollowed portion B in the coloring layer  121 , the RFID  125  may be built in the gaming currency  120  by arranging the RFID  125  between the coloring layer  121  having a flat surface and the white layer  122  having a flat surface and performing thermos-compressing of the coloring layer  121  and the white layer  122  as it is. By configuring at least one of the coloring layer  121  and the white layer  122  using a material such as plastic that can be thermally deformed, out of the coloring layer  121  and the white layer  122  having the RFID  125  interposed therebetween through thermal compression, a plastic layer is thermally deformed, and accordingly, the RFID  125  is tightly fixed between such layers without arranging the hollowed portion B. 
       FIG.  12    is a perspective explanatory photographic diagram that illustrates a state in which gaming currency of different types are piled up. The management control device  14  images gaming currency  120  placed on the game table  1  by the game participant  6  by using the camera device  2  and measures each area  8  (whether the bet is on the banker, the player, the pair, or the tie) in which the gaming currency  120  is placed by using the measurement device  19  including the image analyzing device  18 , and the measurement device  19  (by using information acquired by the image analyzing device  18 ) analyzes and measures the number and the colors of coloring layers  121  (or the thin-color layers) or white layers  122  of the gaming currency  120  that is stacked in each area and determines the types and the quantities of the gaming currency  120 . The management control device  14  performs control of the camera device  2  such that imaging using the camera device  2  is performed when the first card is drawn from the card distributing device, before and after the drawing, or after a dealer&#39;s sign representing the end of betting. 
     The management control device  14  may be a control device having an artificial intelligence-utilizing or deep learning structure. The management control device  14  can perceive the position  8  (a position betting on a player, a banker, or a pair), the types (a value of a different amount is assigned to the gaming currency  120  for each color), and the quantities of the gaming currency  120  that is bet by each participant  6  through the camera device  2  and the image analyzing device  18 . The artificial intelligence-utilizing computer or control system can perceive the position  8  (a position betting on a player, a banker, or a pair), the types (a value of a different amount is assigned to the gaming currency for each color), and the quantities of the gaming currency  120  by using a self-learning function or the like in the deep-learning (structure) technology, and thus, according to a result of winning/losing of a game determined by the card distributing device  3  in each game, determines whether or not the collection (denoted using an arrow L) of gaming currency  120  bet by a losing participant  6 L and the re-payment (payment ( 120 W)) for winning gaming currency  120  for the winning game participant  6 W are appropriately performed according to a result of winning/failure of the game in each game by analyzing a video of the state of progress of the game by using the management control device  14  through the image analyzing device  18 . 
     In such a case, as illustrated in  FIG.  11    (compared to conventional gaming currency illustrated in  FIG.  7   ), a stacked multi-layer structure is formed, and a stripe pattern is formed on the side face in the stacking direction, and accordingly, the measurement device  19  including the image analyzing device  18  can accurately perform the measurement of the types and the quantities of gaming currency in an easy manner. In addition, by using an artificial intelligence-utilizing computer or control system and a deep-learning (structure) technology, the analysis and the determination of the image can be performed more accurately. The artificial intelligence-utilizing computer or control system and the deep-learning (structure) technology are known to persons skilled in the art and can be used, and thus, detailed description thereof will be abbreviated. 
     The management control device  14  can analyze and perceive a total amount of gaming currency  120  in the tray  17  for gaming currency for the dealer  5  of the game table  4  by using the image analyzing device  18  and can determine through a comparison and calculation whether or not a total amount of the gaming currency  120  placed inside the tray  17  for gaming currency has been increased/decreased according to the collection of the losing gaming currency  120  bet by each game participant  6  and the amount of the payment  120 W for winning gaming currency to the winning game participant  6 W after the game ends and is settled based on the result of winning/losing of the game. The total amount of the gaming currency  120  in the tray  17  for gaming currency may be constantly acquired by using means such as RFIDs, and it is determined whether or not the increased/decreased amount is correct by the management control device  14  by analyzing a video of the state of progress of the game through the image analyzing device  18 . For these, an artificial intelligence-utilizing or deep-learning structure may be utilized. 
     In addition, the management control device  14  may have an artificial intelligence-utilizing or deep-learning structure capable of acquiring the position (a position for betting on the player, the banker, or the fair) and the amount (the types and quantities) of bet gaming currency at each player position  7  of the game table  4 , comparing a winning/losing history of each player  6  and the amount (won amount) of acquired gaming currency that can be acquired based on the result of winning/losing of each game with statistical data of many (big data) games in the past, and extracting an abnormal situation (set in the casino). Typically, the management control device  14  is included which has an artificial intelligence-utilizing or deep-learning structure capable of extracting an occurrence of a won amount of a certain amount (one million dollars) or more and an abnormal situation in which, in a play position  7  of a specific game table  4 , a state in which the amount of bet gaming currency is small at the time of losing a game, and the amount of bet gaming currency is large at the time of winning a game is continued for several games and is determined as an abnormal situation based on a comparison with statistical data (big data or the like) of games in the past. 
     The total amount of the gaming currency  120  in the tray  17  for gaming currency for the dealer  5  of the game table  4  is settled for the gaming currency  120  bet by each participant  6  after each game, and the management control device  14  has a structure capable of determining through a comparison and calculation whether or not an increase/decrease in the gaming currency that corresponds to a settlement is correct after the settlement. 
     In the tray  17  for gaming currency used for storing the gaming currency  120  for the dealer  5  illustrated in  FIG.  6   , the types and the quantities of the gaming currency  120  can be determined by analyzing and measuring the numbers and the colors of the coloring layers  121  or the white layers  122  of the gaming currency  120  stacked in the horizontal direction by using the measurement device  19  (by using the information acquired by the image analyzing device  18 ). The total amount of the gaming currency  120  for the tray  17  for storing gaming currency is constantly (or at predetermined time intervals) acquired in this way. As the management control device  14  has a calculation function of calculating a settlement amount (calculation of a balance of the casino side in the game table  4  (an amount acquired by subtracting a total amount of the gaming currency  120  re-paid to the winner  6 W among the participants  6  from a total amount of the gaming currency  120  bet by the loser  6 L) of each game for each game (see description presented above), the total amount of the gaming currency  120  of the tray  17  for gaming currency is constantly (or at intervals of a predetermined time) is verified. That is, it is verified whether or not an increase/decrease in the gaming currency matches a result of an image analysis performed by the image analyzing device  18  and the settlement amount of each game performed by the dealer  5 . 
       FIG.  13 A  is a diagram that illustrates details of a tray for gaming currency according to this embodiment, and  FIG.  13 B  is a diagram that illustrates another example of the gaming currency. In the tray  17  for gaming currency, a collection tray  171  for gaming currency that is used for collecting and temporarily storing gaming currency  120 L for gaming that is bet by a losing player  6 L and a repayment tray  172  for gaming currency  120 W for gaming that is used for storing gaming currency  120 L for gaming to be re-payed are arranged. The image analyzing device  12  and the control device  14  acquire the position, the type, and the quantity of gaming currency  120 L for gaming that is bet by the losing player  6 L and calculates an increased amount (an amount of gaming currency  120 L for gaming to be present in the collection tray  171  for gaming currency  120 ) of gaming currency  120 L for gaming in the game. In addition, the image analyzing device  12  and the control device  14  acquire a real total amount of the gaming currency  120  in the tray  171  for gaming currency after the collection and determine whether or not there is a difference between the total amount and the real total amount through a comparison. 
     Here, the tray  17  for gaming currency that is illustrated above has a two-stage structure formed by an upper stage tray  17   a  for gaming currency and a lower stage tray  17   b  for gaming currency.

     By using this inspection device  200 , it can be inspected whether or not the print  123  of the manufactured gaming currency  120  matches the type of the gaming currency according to the color of the stripe pattern of the gaming currency  120  and is correctly printed. 
     As above, the gaming currency  120  according to this embodiment has a stacked structure, in which the coloring layer  121  and the white layer  122  or thin-color layers having the coloring layer  121  interposed therebetween are stacked, formed by a plurality of plastic layers and thus, has a side face on which a stride pattern is formed in the stacking direction. The gaming currency  120  has a configuration enabling the type of the gaming currency  120  to be specified using the coloring layer  121  appearing on the side face. In addition, prints are performed for the upper face and the lower face of the gaming currency  120 . More specifically, prints are performed for the surface of the white layer  122  of the thin-color layer, and the transparent layer  124  is included on the upper face thereof. The coloring layer  121  and the white layer  122  or the thin-color layer and the print layer  124  are thermos-compressed together to form a layered structure. 
     The white layers  122  or the thin-color layers having the coloring layer  121  interposed therebetween may be configured to have different depths in the vertical direction from each other. 
     In addition, in this embodiment, the R processing is performed for the outer edges of the upper face and the lower face of the gaming currency  120 . Accordingly, it can be prevented that a player&#39;s hand handling the gaming currency  120  hurts, or the gaming currency  120  damages the other gaming currency  120 . 
     In addition, in this embodiment, the RFID  125  is tightly fixed between plastic layers each forming one of the coloring layer  121  and the white layer  122  or the thin-color layer. 
     In addition, in this embodiment, on the upper face and/or the lower face of the gaming currency  120 , face codes using UV emission ink, infrared absorption ink such as ink (carbon black ink) absorbing infrared rays are arranged. In addition, as a modified example of this embodiment, one or both of a security mark and an optical variable device (OVD) may be printed on the surfaces of the gaming currency  120  instead of the face codes or together with the face codes. 
     In addition, the gaming currency  120  according to this embodiment has a structure in which the side ID  126  is attached to the side face, the RFID  125  is built, and face codes using UV emission ink or infrared absorption ink are arranged on the upper face or the lower face (the print layer  124 ). Then, the information of a side ID  126  and the information of an RFID  125  are associated with each other, the information of a side ID  126  and information of a face code are associated with each other, or the information of a side ID  126 , information of an RFID  125 , and the information of a face code are associated with each other. 
     In addition, the inspection device  200  according to this embodiment includes: the measurement device  19  of the type of gaming currency  120  that images the side face of the gaming currency  120  and determines the color of the stripe pattern of the side face in the stacking direction; and the mark reading device  205  that reads the print of the gaming currency. In this way, a relation between the type of gaming currency and the content of a print can be inspected. 
     The management control device  14  according to this embodiment performs imaging for determining the position, the types, and the quantities of gaming currency placed by a game participant in each game when the first card is drawn from the card distributing device  3 , before and after drawing, or after a dealer&#39;s sign representing the end of betting. 
     In addition, the gaming currency  120  according to this embodiment is manufactured as below. First, a stacked structure body including a plurality of plastic layers is formed by heating and pressing the coloring layer  121  and the white layers  122  or the thin-film layers. Then, a drawing pattern is printed at least on the upper face or the lower face of the stacked structure body, whereby a gaming currency original plate is generated. Then, punching processing is performed for the gaming currency original plate by using a mold, whereby a plurality of gaming currencies having a predetermined shape are acquired.

By performing imaging the two camera devices  2   b - 1  and  2   b - 2 , gaming currency  120  disposed at a place that is in a blind area for one of the camera devices can be imaged as well. 
     In a plurality of cashiers  60  present in a game house, the gaming currency  120  is exchanged with cash  61  paid by a game participant  6 , and, in each cashier  60 , gaming currency  120  is stored in a storage  62  storing the gaming currency  120 . In each cashier  60  of a game house, gaming currency  120  brought by a game participant  6  is refunded into cash  61 . In the game table  4 , gaming currency  120  is stored in a game table gaming currency tray  17 , and a dealer  5  collects gaming currency  120  bet by a game participant  6  who has lost the game from the table  4  in each game, returns the collected gaming currency  120  to the game table gaming currency tray  17 , and then re-pays the gaming currency  120  to a game participant  6  who has won each game. All such exchanges between a game participant  6  and a cashier  60  of a game table or a dealer  5  are imaged and recorded by all the camera devices  2 . In the storage  62  or the game table gaming currency tray  17 , when there is exchange of gaming currency  120  with a game participant  6 , the gaming currency  120  stored in the storage  62  or the game table gaming currency tray  17  increases or decreases. The types and the quantities of the gaming currency  120  stored in the game table gaming currency tray  17  and the storage  62  are monitored at predetermined timing or constantly by the ID reading device  53  and the gaming currency determining device  52  through the camera device  2 . The management control device  50  stores the side IDs  126  of all the gaming currency  120  assumed to be used in a game house in the database  51  in advance (the side IDs  126  of all the gaming currency  120  assumed to be used in the game house are registered). 
     In addition, also in this embodiment, the gaming currency tray  17 , as illustrated in  FIGS.  14 A and  14 B , may be configured by an upper gaming currency tray  17   a  and a lower gaming currency tray  17   b  of upper/lower two stages. In such a case, in the state illustrated in  FIG.  14 A , the upper gaming currency tray  17   a  can be imaged by the camera device  2 , and, in the state illustrated in  FIG.  14 B , the lower gaming currency tray  17   b  can be imaged by the camera device  2 . In the state illustrated in  FIG.  14 B , additionally, the upper gaming currency tray  17   a  and the lower gaming currency tray  17   b  can be imaged by the camera device  2   c  simultaneously and also in an individually-identifiable state. In addition, in the state illustrated in  FIG.  14 B , the upper gaming currency tray  17   a  and the lower gaming currency tray  17   b  may be separately imaged. Each of the camera devices  2  and  2   c  may include a single visible-light camera or a single infrared ray camera corresponding to ink printed for the side ID  126  or a camera capable of performing switching among a plurality of functions of a visible-light camera and an infrared-ray camera corresponding to the printed ink. 
     In this way, in the game house, by using the database  51 , the management control device  50  managing the side IDs  126  associated with gaming currency  120  manages all the side IDs  126  of at least gaming currency  120  present in the game table gaming currency tray  17  and the storage  62  in the database  51  together with the presence information thereof (the storage  62 , the game table gaming currency tray  17 , in the middle of moving from a backyard (not illustrated in the drawing), held by a game participant  6 , or the like). The management control device  50  specifies all the gaming currency  120  disposed in the game table gaming currency tray  17  and the storage  62  by using the side IDs  126  at predetermined timing or constantly, searches the database  51 , and determines the following events through the search of the database  51 : 
     1) A side ID  126  that has not been present (or not present) in the database  51  is determined to be newly present.
 
2) Two or more same IDs are determined to be present.
 
     The management control device  50  has a function of generating an error signal representing an abnormality and giving a notification to a management division or a security division  54  of the game house when the situation of 1) or 2) described above is present. The management control device  50  specifies all the gaming currency  120  disposed in the game table gaming currency tray  17  and the storage  62  at predetermined timing or constantly by using the side IDs  126  and stores all the gaming currency  120  in the database  51  and thus, can determine that 1) a side ID  126  that has not been present (or not present) in the database  51  is newly present and 2) two or more same IDs are present. 
     In addition, when there is a change in the presence of the gaming currency  120  at least in the game table gaming currency tray  17  and the storage  62 , the management control device  50  records time or a place (the storage  62 , the game table gaming currency tray  17 , or the like) at which the change is present in the database  51  in association with the side ID  126  and, as a result of the search of the database  51 , when there is a situation in which two or more same side IDs  126  are present, extracts the side ID  126  and information of time or a place recorded in the database  51  in association with the side ID  126  from the database  51  and stores the side ID and the information that have been extracted, and thus, time at which gaming currency  120  to which the side ID  126  is attached, which has been detected first (used first or cashed), enters/exits the game table gaming currency tray  17  or the storage  13  or a place of the game table gaming currency tray  17  or the storage  13  in which the gaming currency  120  is stored can be specified by using the database  51 . When the time and the place can be specified, a suspicious person for the use of unjust gaming currency  120  or the like can be specified from the recorded video of the camera device  2 . 
     In this management system of gaming currency, the management control device  50  can specify the types and the quantities of the gaming currency  120  bet on the bet area  8  of the game table  4  by using the ID reading device  53 . The gaming currency  120  of the bet area  8  is imaged by the camera device  2   b  that particularly images the bet area  8  and, also for the side ID  126  of the gaming currency  120  present on the bet area  8  of the game table  4 , determines the following events by searching the database  51 : 
     1) A side ID  126  that has not been present in the database  51  is newly present in the bet area  16 ;
 
2) Two or more same IDs are present.
 
     The management control device  50  has a function of generating an error signal when a situation of 1) or 2) described above is present. 
     The management control device  50  of this system, the ID reading device  53  disposed inside, and the gaming currency determining device  52  specifying the types and the quantities of gaming currency  120  have a structure integrally including a computer formed as one body or by a plurality of configurations, a program, and a memory. 
     Next, details of gaming currency  120  (so-called gaming currency) used in this system will be described.  FIG.  17    is a side view of gaming currency  120  used in this system, the gaming currency  120  is formed by stacking a plurality of plate-shaped plastic layers having different colors, forming the plastic layers to be integrated using a means of thermo-compressing or the like, and then, punching holes in the shapes of circles and quadrangles. The gaming currency  120  manufactured in this way has a multi-layer structure in which a coloring layer  121  is included at least in the middle, and white layers  122  or thin-color layers (may be layers of a color thinner than that of the coloring layer  121 ; not illustrated in the drawing) are stacked on both sides (in  FIG.  17   , the upper and lower sides) of the coloring layer  121  disposed in the middle. In this way, by employing the multi-layer structure in which the coloring layer  121  is included, and the white layers  122  or the thin-color layers (may be layers of a color thinner than that of the coloring layer  121 ; not illustrated in the drawing) are stacked on both sides of the coloring layer  121  disposed in the middle, as illustrated in  FIG.  17   , a stripe pattern (in the stacking direction) when seen from the side face is formed, and, by changing the color (red, green, yellow, blue, or the like) of the coloring layer  121  for each type (10 points, 20 points, 100 points, 1000 points, and the like) of the gaming currency  120 , the type of the gaming currency  120  can be specified. 
     In addition, as illustrated in  FIG.  17   , in the gaming currency  120 , a side ID  126  representing the type of gaming currency  120  is applied to the side faces of the white layers  122 . 
     In the outermost layers, transparent layers  124  are arranged, and each interlayer is thermo-compressed to form a structure of at least five layers. Such gaming currency  120  is formed by using a plastic material having a thin long shape, and layers (at least the coloring layer  121  and the white layers  122 ) are thermo-compressed to form a closely adhering state (the structure of five layers or the like) in the state of a long length, and thereafter, holes having a circular shape, a rectangular shape, or the like are formed therein through press or the like. When a hole is formed through the press, die of mold for punching, and the size of punching are designed, and R processing (round angle) is performed for the ends of the transparent layer  124  of the outermost layer. The transparent layers  124  may be a coat layer of varnish. The side ID  126  is attached to at least three positions on the side face of the gaming currency  120 . The side ID  126  is attached through inkjet printing using ink that is visible for visible light. 
     Particularly, in this embodiment, the side ID  126  is configured to be attached as presence/absence of marks C of a plurality of rows and a plurality of columns. In the marks C of the plurality of rows and the plurality of columns, as illustrated in  FIG.  17   , upper and lower marks C are paired to configure a code, and a code of ten digits is formed in the case illustrated in  FIG.  17   . A configuration in which upper and lower marks C are paired to configure a code (four types) is illustrated in  FIG.  18   . A letter “Y” disposed to the side of marks C is an identification mark used for identifying upper and lower sides of a mark. A code configured by marks C is configured to specify a predetermined combination of marks C. As a result, in the example illustrated in  FIG.  18   , there are four types of combination of the marks C of upper and lower two columns, and, by printing these in ten columns, four to the power of 10 codes can be configured. Since there are four types of a 10-digit code, 4 to the power of 10 codes are acquired, and accordingly, the side IDs  126  of gaming currency  120  can be sufficiently assigned. 
     The gaming currency  120  forms a stripe pattern on the side face in the stacking direction by employing a multi-layer structure in which a plurality of plastic layers having different colors are stacked, the coloring layer  121  is included at least in one layer, the white layers  122  or the thin-color layers are stacked on a further outer side than the coloring layer  121  and has a configuration enabling the type of the gaming currency  120  to be specified using the coloring layer  121 . The side IDs  126  are disposed at least three positions (preferably, six positions) on the side face of the white layer  122  or the thin-color layer, and, in this example, six side IDs are disposed at a predetermined interval of 60 degrees in the rotation direction (circumferential direction). The side IDs  126  individually identifiable (different for each one) are attached to gaming currency  120 , and the side IDs  126  are disposed at a predetermined interval of 60 degrees in the rotation direction (circumferential direction) such that the side ID is necessarily seen from the lateral side. The side IDs  126  attached to the gaming currency  120  are read by the ID reading device  53  described above. The type, the manufacturing information, and the like of gaming currency  120  can be specified by reading the side ID  126  by using the ID reading device  53 , and a configuration in which the side ID  126  can be managed in the database  51  is formed. In this embodiment, the side IDs  126  are attached using ink (visible ink) that is visible for visible light through inkjet printing. The side IDs  126  may be printed using at least one or a combination of ink (ink absorbing infrared rays) that is not visible for visible light and ink (including a side ID that is very small and is difficult to see) that is visible for at least visible light. In addition, the side IDs  126  may be printed by combining a plurality of such ink of a plurality of types. The ID reading device  53  includes at least a plurality of cameras (that is, a visible-light camera in a case where ink is visible ink, an infrared-ray camera in a case where ink is infrared reactive ink, and an ultraviolet camera in a case where ink is UV ink (UV radiator and a visible-light camera)) corresponding to the ink used for printing the side ID  126  or includes a camera capable of performing switching among a plurality of functions of cameras (a visible-light camera, an infrared ray camera, and an ultraviolet ray camera (an UV radiator and a visible-light camera or the like)) corresponding to the ink. 
     In the case illustrated in  FIG.  19   , in gaming currency  120 - 1 , side IDs  126  are printed using ink (ink absorbing infrared rays) that is not visible for visible light. In gaming currency  120 - 2 , marks C of a plurality of rows and a plurality of columns are printed using ink that is seen dark for visible light. In gaming currency  120 - 3 , additionally, marks C are printed using ink seen dark for visible light also between the side IDs  126 , and the side IDs  126  are configured to dissolve in the design not to be visually distinguished. In gaming currency  120 - 4 , a start point and an end point of the side ID  126  are represented by a mark Cf representing the end. When the gaming currencies  120 - 1  to  120 - 4  are seen using an infrared-ray camera, ink absorbing infrared rays absorbs infrared rays to be seen dark, and the gaming currencies  120 - 1  to  120 - 4  can be imaged in a state (represented as the gaming currency  120 - 5 ) in which the side ID  126  can be read. In addition, the upper and lower sides of the side ID  126  are illustrated using a mark CL representing the upper and lower sides. A relation between the upper and lower sides of the mark is as illustrated in  FIG.  17   . In addition, the side IDs  126  may be printed using a combination of ink that is visible for visible light and an infrared ray absorption ink. 
     The side IDs  126  attached to the gaming currency  120  are read by the ID reading device  53  described above, and the ID reading device  53  can read the gaming currency  120  held in the storage  62  of a cashier of a game house and the game table gaming currency tray  17  of the game table, and actually, as illustrated in  FIG.  20 A , when the gaming currency  120  is stacked horizontally, the side IDs  126  can be read. In addition, the gaming currency  120  stacked in the bet area  8  or the like, as illustrated in  FIG.  20 B , can be also read. 
     Furthermore, in the gaming currency  120 , a face code using UV ink or ink (carbon black ink) absorbing infrared rays is arranged on the surface (X) of the white layer  122  (see  FIG.  9 B ). This face code represents authenticity of gaming currency  120 , and, when ultraviolet rays (or infrared rays) hit the face code, the face code becomes visible to the eyes and represents authenticity based on a combination of the forms and a number. While the transparent layers (print layers)  124  are thermos-compressed or coated in the outermost layers to cover a print  123  (100 points or the like) used for specifying a game house and a face code disposed on the surface, embossing process or varnish processing is performed for the transparent layers  124 , and the gaming currency  120  is prevented from adhering to each other and is caused to slide well. In the gaming currency  120 , a circular recess  127  is arranged at the center of each of the upper and lower faces. According to the recesses  127 , the gaming currency  120  is prevented from being adhere to each other, and, by increasing the diameter of the recesses  127 , the gaming currency  120  can slide well. 
     The R processing (R) is performed for the ends of the transparent layers (print layers)  124  of the outermost layers for which a print  123  (100 points or the like) is performed, and, in the punching process of the gaming currency  100 , the surfaces of the white layers  122  are prevented from being deformed to appear on the side face. In addition, it is prevented that a sharp end remains in the gaming currency  100  and damages the hands or the other gaming currency  120 . The coloring layer  121  may be formed by colored one layer or a plurality of layers. In addition, metal or ceramic used for increasing the weight may be built in a layer included in the layer of the coloring layer  121 . More specifically, in the material of the layer included in the layer of the coloring layer  121 , for example, metal powders (for example, a metal oxide of one or a plurality of metal oxides of zinc oxide and titanium oxide) may be contained. In addition, a part of the coloring layer  121  is hollowed out, or a space is arranged between the coloring layer  121  and the white layer  122 , and an RFID may be built therein. In such a case, as the side ID  126  of the gaming currency  120 , a side ID  126  according to a code using the marks C and a side ID using the RFID are used together. 
     In the gaming currency  120  configured in this way, the types and the quantities of the gaming currency  120  that is held in the game table gaming currency tray  17  and the storage  62  are specified by the gaming currency determining device  52  through the camera device  2  and the ID reading device  53 , and the side IDs  126  of the gaming currency  120  present on the game table gaming currency tray  17  and the storage  62  are managed in the database  51  together with the presence information thereof. In this way, at least, it is inspected whether 1) a side ID  126  that has not been present in the database  51  is newly present 2) two or more same side IDs  126  are present. By determining the occurrences of the situations of 1) and 2) described above by searching for all the side IDs  126 , the inspection is realized. 
     As described above, while a game participant  6  can perform exchange of cash  61  for gaming currency in the cashier  60 , exchange of cash  61  for gaming currency  120  can be performed also in the game table  4 .

     The fourth embodiment relates to an inspection system and an inspection device for inspecting a gaming currency, and more specifically, to an inspection system and an inspection device for inspecting plural gaming currencies housed in a case. 
     Gaming currencies used in a gaming house such as a casino are manufactured in a factory, are carried to the gaming house to be stored in a repository, and moved from the repository to a cashier or a game table in the house, it is necessary to prevent the gaming currencies from being stolen or replaced with a fake during carrying, storing, and moving. Therefore, the case housing the gaming currencies is used. Since the case is stamped after housing the plural gaming currencies, it is possible to discover a situation in which the gaming currencies are extracted from the case after stamping. 
     As the gaming currency, it is known the one in which a radio tag storing identification information or information on kinds is built and a optically readable code information indicating the identification information or the information on kinds is given on a side surface (for example, Japanese Patent Laid-Open No. 2009-66172). 
     In Japanese Patent Laid-Open No. 2009-66172, a system using a gaming currency is disclosed. The system calculates, for the gaming currencies placed on a betting board on a game table, the number of the gaming currencies based on the identification information stored in the radio tag, calculates the number of the gaming currencies based on the identification information given to the side surface, and compares them. Thereby, if unfair gaming currencies are used on the game table, it can be detected. 
     However, since the system disclosed in Japanese Patent Laid-Open No. 2009-66172 detects injustice by calculating the number of the gaming currencies betted (placed on the betting board), even with this system, it is impossible to detect unfair gaming currencies by inspecting the plural gaming currencies housed in the case while being housed in the case. 
     Then, the purpose of the fourth embodiment is to provide an inspection system and an inspection device capable of inspecting plural gaming currencies housed in a case while being housed in the case. 
     An inspection system according to a first aspect of the fourth embodiment is an inspection system for inspecting a gaming currency having at least first currency information and second currency information, the second currency information being provided on a side surface of the gaming currency in a form which can be optically read, including: a case which stacks and houses plural gaming currencies; and an inspection device which inspects the gaming currencies housed in the case, in which the inspection device includes: a first reading device which obtains the first currency information of the gaming currencies housed in the case; a second reading device which optically reads the side surfaces of the gaming currencies housed in the case and obtains the second currency information; and a determination part which determines authenticity/damage or a number for each value of all gaming currencies existing in the case to determine pass or fail of the plural gaming currencies housed in the case by using the first currency information obtained by the first reading device and the second currency information obtained by the second reading device. 
     According to this configuration, since a first reading part and a second reading part obtain the first currency information and the second currency information from the gaming currencies housed in the case respectively, it is possible to perform inspection with respect to the gaming currencies while being housed in the case. Also, since the inspection is performed by obtaining two pieces of information, the first currency information and the second currency information from the gaming currencies, it is possible to certainly perform the determination of the pass or fail. 
     In an inspection system according to a second aspect of the fourth embodiment, in the inspection system according to the first aspect, the first currency information and the second currency information on the common gaming currencies include common information, and if a common information part of the plural pieces of the first currency information obtained by the first reading device is not equal to that of the plural pieces of the second currency information obtained by the second reading device, the determination part determines the plural gaming currencies housed in the case are as fail. 
     According to this configuration, when unfair gaming currencies in which the common information part of the first currency information is not equal to that of the second currency information exist, the determination part can reject the gaming currencies housed in the case. 
     For example, if common identification information is recorded on the radio tag and the side surface, it is rejected, if plural pieces of identification information read out from the plural radio tags are not perfectly equal to plural pieces of identification information read out from the plural side surface. 
     In an inspection system according to a third aspect of the fourth embodiment, in the inspection system of the first aspect, both or either one of the first currency information or the second currency information includes individual identification information for individually identifying the gaming currencies.

That is, the gaming currency C has the specific coloring layer  4501  that is the middle layer, the common coloring layers  4502  sandwiching the specific coloring layer  4501  from both surfaces, and transparent layers  4504  which are the most outer layers of both sides. 
     The gaming currency C is formed by long and thin elongated five layers (in the order of the transparent layer  4504 , the common coloring layer  4502 , the specific coloring layer  4501 , the common coloring layer  4502 , and the transparent layer  4504 ) of plastic material, disposing the RFID tags  4503  at predetermined intervals between the specific coloring layer  4501  and the one common coloring layer  4502  at that time, thermocompression bonding the five layers of the plastic material, and then punching that in a circular or rectangular shape by pressing and the like so that one gaming currency C includes one RFID tag  4503 . When punching by pressing, R machining (a rounded corner) is applied at an edge of the most outer transparent layer  4504  by designing the dimensions of die and punch for a mold for punching. 
     Three layers composed of the specific coloring layer  4501  and two layers of the common coloring layers  4502  are thermocompression bonded, then varnish is applied on surfaces, and thus the transparent layers  4504  may be formed. Also, the specific coloring layer  4501  and the two common coloring layers  4502  need not be separate members, and after being integrally formed, the specific color (and the common color) may be applied on the side surface by inkjet printing and the like, thereby forming the specific coloring layer  4501  and the common coloring layers  4502 . 
     The specific coloring layer  4501  expresses values (kinds) of the gaming currencies C with a color (the specific color). That is, since the color of the specific coloring layer  4501  is made to be different colors (red, green, yellow, blue, etc.) for the respective values of the gaming currencies C, by checking the color of a specific coloring layer  501  that can be optically read from the side surface of the gaming currency C, the value (such as 10 points, 20 points, 100 points, 1000 points, etc.) of the gaming currency C can be specified. On the common coloring layers  4502 , the common color (common color) is applied on the gaming currencies C having different values. The common color is preferably lighter than any specific color, and it is white in the present embodiment. 
     On the side surface of the gaming currency C, furthermore, on the side surface (specifically, on the common coloring layers  4502  of the side surface), code information  4505  representing the currency information of the gaming currency C is indicated. The code information  4505  expresses the information according to the layout of plural labels (they may be referred to as marks and are square labels in the present embodiment). The specific coloring layer  4501  represents the information (the value of the gaming currency C) with the color, whereas, the code information  4505  expresses the information with the label indicated on the side surface, so that it may be referred to as indication information. Other examples of the indication information include plural character strings, number strings, bar codes, and the like. 
     The code information  4505  of the present embodiment is repeatedly indicated at a cycle of 60 degrees in a circumferential direction of the gaming currency C. Thereby, when the side surface of the gaming currency C is observed in the circumferential direction from any direction, the complete code information  4505  is included in a range of 120 degrees in the circumferential direction. Note that the repeating cycle of the gaming currency C is not limited to 60 degrees, and the code information  4505  may be repeatedly indicated at equal intervals in the circumferential direction at least three times. 
     The code information  4505  is indicated by invisible ink. In the present embodiment, by using the infrared-ray absorbing ink for absorbing infrared rays (specifically, carbon black) as the invisible ink, the code information  4505  is printed by inkjet printing. Since only the printed part of the code information  4505  does not reflect infrared rays, by shooting the side surface of the gaming currency C with the infrared-ray camera  4225 , the code information  4505  will emerge. Note that in order to make the printed part clearly emerge, the infrared-ray camera  4225  may include an infrared-ray lamp and irradiates infrared rays to the side surface of the gaming currency C to be shot. 
     Note that the invisible ink is not limited to the infrared-ray absorbing ink, but may be an infrared-ray responsive ink that fluoresces in response to infrared rays or a UV ink that fluoresces in response to ultraviolet rays. In the case of using the UV ink, an ultraviolet-ray camera is used instead of the infrared-ray camera  4225 , and in order to cause the UV ink to fluoresce, a black light irradiating ultraviolet rays to the side surface of the gaming currency C is used. 
     Furthermore, the gaming currency C is provided with a label (mark) m′ by the UV ink or the carbon black ink on a surface X of the common coloring layer  4502 . The label m′ represents the authenticity of the gaming currency C, and upon irradiation with ultraviolet rays (or infrared rays), the label m′ becomes visible and represents a genuine one by the combination of its shapes or numbers. In order to cover printing  4506  (100 points and the like) for specifying a gaming house or the label m′ on the surface, although the transparent layer  4504  is thermocompression bonded or coated (applied) on the outermost layer, embossing or varnishing is performed on the transparent layer  4504 , thereby preventing the gaming currencies from adhering to each other and improving slippage. 
     R machining (R) is performed on an edge of the transparent layer  4504  of the outermost layer which has been subjected to the printing  4506  (100 points and the like), thereby preventing the surface of the common coloring layer  4502  from deforming and appearing on the side surface, in a punching process of the gaming currency C. Also, a sharp edge of the gaming currency C is prevented from damaging a remaining hand or other gaming currencies C. The specific coloring layer  4501  may be formed by one or more colored layers. Furthermore, metals and ceramics for increasing weight may be interiorized in the layer in the specific coloring layer  4501 . Also, the RFID tag  4503  may be built by hollowing out a part of the specific coloring layer  4501 , or in a space provided between the specific coloring layer  4501  and the common coloring layer  4502 . 
       FIG.  28    is a diagram showing an example of an image obtained by shooting the plural gaming currencies C housed in the case  4100  with the infrared-ray camera  4225  and the visible-light camera  4226 . The case  4100  in this case may be a two-stage chip float (especially a movable upper tray part in a two-stage chip tray) or a chip tray for holding the gaming currencies C on a game table. Even if the gaming currencies C are vertically stacked in the case  4100  as shown in  FIG.  28   , the infrared-ray camera  4225  and the visible-light camera  4226  can shoot the code information  4505 . Also, by vertically counting the specific coloring layers  4501 , it is possible to count the number of the gaming currencies C. Even in a two-stage system, by developing each stage, it is possible to shoot the side surfaces of all gaming currencies C housed in the case  4100  with the infrared-ray camera  4225  and the visible-light camera  4226 . 
     In the present embodiment, the code information  4505  is expressed by the layout of the labels m with multiple rows and multiple columns.  FIG.  29    is a diagram for explaining a configuration of the code information  4505 . As shown in  FIG.  29   , the upper and lower labels m make a pair to form one code element. In the example of  FIG.  29   , one piece of the code information  4505  is composed of ten-digit code elements. As shown in  FIG.  29   , there are four patterns in the one code element formed by the upper and lower labels m making the pair, and one code element can express four types of information, so that the code information  4505  composed of the ten-digit code element can express  4  to the tenth power kinds of information. A letter Y next to the ten-digit code element is an orientation discrimination mark Y for discriminating the orientation of the code information  4505 . 
       FIG.  30    is a block diagram showing a configuration of the inspection device  4200 . The inspection device  4200  includes a barcode reader  4228  and a communication part  4229 , in addition to the RFID reader  4221 , the computer  4222 , the display part  4223 , the RFID antenna  4224 , the infrared-ray camera  4225 , and the visible-light camera  4226  which are shown in  FIG.  25   . Also, the computer  4222  is composed of a processor, a memory, and the like which are not shown, and the processor executes an inspection program to configure an identification part  4230  and the determination part  4231 . 
     An RFID system is composed of the RFID reader  4221 , the RFID antenna  4224 , and the RFID tag  4503  embedded in the gaming currency C. The currency information of the gaming currency C stored in the RFID tag  4503  embedded in the gaming currency C is read out by the RFID reader  4221  without contacting, and used for processing in the computer  4222 . 
     The infrared-ray camera  4225  includes an infrared-ray transmission filter transmitting infrared rays only, and picks up an infrared-ray image. The infrared-ray image produced by the shooting of the infrared-ray camera  4225  is sent to the computer  4222 , and is subjected to the processing of the identification part  4230 . The visible-light camera  4226  picks up an image of light in a visible area. Also, the visible-light image produced by the visible-light camera  4226  is sent to the computer  4222 , and is subjected to the processing of the identification part  4230 . As shown in  FIG.  25   , the infrared-ray camera  4225  and the visible-light camera  4226  are oriented to the case  4100  from an upper part of the case  4100 , and shoot the side surfaces of the plural gaming currencies C in the case  4100  over the top part  4101  of the case  4100 . 
     The barcode reader  4228  reads a barcode BC attached to the case  4100  to obtain case identification information described below. The display part  4223  displays a determination result of the determination part  4231  of the computer  4222 . The communication part  4229  performs data communication with a manufacture management device  4302  installed in a factory F or a use management device  4303  installed in a gaming house P. 
       FIG.  31    is a perspective view of the case  4100 . The case  4100  is formed by joining the top part  4101  and the lower part  4102 . In the present embodiment, the top part  4101  and the lower part  4102  are made of a transparent resin. As described above, in inspection device  4200  of the present embodiment, since the infrared-ray camera  4225  and the visible-light camera  4226  (hereinafter, simply referred to as a camera) are installed above the receiving part  210 , it is necessary that at least the upper surface of the case  4100  transmits light. That is, in the case  4100 , it is necessary that a part positioned between the case  4100  and the camera when being received in the receiving part  4210  of the inspection device  4200  is a light transmission part which transmits light. Note that in the present embodiment, although the case  4100  is a sealed structure composed of the top part  4101  and the lower part  4102 , the light transmission part may be in a perforated state. 
     The case  4100 , as described above, has a shape formed with five columns in which respective 20 gaming currencies C are stacked and housed, in parallel, and in an example of  FIG.  31   , a cross section of each column is polygon (octagon) so that the top part  4101  and the lower part  4102  generally conform the shape of the gaming currencies C to be housed. 
       FIG.  32    is a perspective view of the case  4100 ′ of a modification, and  FIG.  33    is a plan view of the case  4100 ′. Also, the case  4100 ′ is composed of a top part  4101 ′ and a lower part  4102  which are made of a transparent resin. In the present modification, an upper surface of the top part  4101 ′ facing the camera is formed by a plane. Thus, by making the surface facing the camera plane, as shown in  FIG.  33   , linear shadows due to corners of the polygonal cross section of the case  4100 ′ do not appear on the camera, and information of the side surface of the gaming currency C can be accurately identified, in an image analysis with respect to a shooting image of the camera. 
       FIG.  34    is a diagram for explaining an example of a usage aspect of the inspection system  41  together with the distribution of the gaming currencies C. The gaming currencies C are manufactured by a manufacturing device  4301  in the factory F (s1), and respective 100 currencies are housed in the case  4100  (s2). The case  4100  is stamped with a stamp seal in the factory F after housing the gaming currencies C. Also, in the case  4100 , the barcode BC indicating the case identification information for uniquely specifying the case  4100  is affixed to the side surface (s3). 
     At that time, in the manufacture management device  4302  in the factory F, the case identification information of the barcode BC affixed to the case  4100  is input (s4). Also, the case  4100  housing the gaming currencies C is subjected to the inspection device  4200  to read currency information (the details will be described below) given to the gaming currencies C, and the inspection of pass or fail is performed. Then, the currency information read from the gaming currencies C housed in the case  4100  is sent to the manufacture management device  4302  (s5), and are associated with the case identification information by the manufacture management device  4302 . Note that the manufacture management device  4302  may be a personal computer. 
     The case  4100  which has been passed in the inspection device  4200  in the Factory F is transported from the factory F to the gaming house P (s6). The case  4100  is firstly stored in a repository R in the gaming house P (s7). The inspection device  4200  is installed in the repository R, and the case  4100  delivered from the factory F is inspected by the inspection device  4200 . 
     On the other hand, from the manufacture management device  4302  in the factory F, the case identification information and the currency information associated with that are sent to the use management device  4303  in the gaming house P. The use management device  4303  includes a storage part which obtains the case identification information and the currency information associated with that from the manufacture management device  4302 , for each of the plural cases  4100  housing the gaming currencies C, and stores them for each case  4100 . Note that the use management device  4303  may be a personal computer. 
     In inspection by the inspection device  4200  in the repository R, the inspection is performed by using the information stored in the use management device  4303 . The case  4100  which has been passed in the inspection in the repository R is carried to a game table T (s9), or is carried to a cashier CA (s10). The game table T and the cashier CA respectively comprise the inspection devices  4200 , and the case  4100  housing the gaming currencies C is inspected by the inspection devices  4200  while being stamped. In the game table T and the cashier CA, the inspection of the case  4100  housing the gaming currencies C which have been used is also performed, and the inspection devices  4200  are used for the inspection. In inspection in the three inspection devices  4200  in the gaming house P, the case identification information and the currency information associated with that sent from the manufacture management device  4302  and stored in the use management device  4303  are referred to. 
       FIG.  35    is a diagram showing an example of content of information which is generated by the manufacture management device  4302 , is sent to the use management device  4303 , and is stored in the use management device  4303 . The information is generated for each case  4100 , and with each of the case identification information (Ca1, Ca2, Ca3 . . . ), the currency information of the plural ( 100  in the present embodiment) gaming currencies C housed in the case  4100  is associated. 
     As the currency information, the RFID tag  4503  stores information made from the combination of individual identification information (aa, ab, ac, . . . , du, and dv) which uniquely specifies the gaming currency C and information (r, r, r, . . . , b, and b) which specifies the value (kind) of the gaming currency C. Indication information on the side surface stores information made from the combination of individual identification information (00001, 00002, 00003, . . . , 00099, and 00100) which uniquely specifies the gaming currency C and information (1, 1, 1, . . . , 2, and 2) which specifies the value (kind) of the gaming currency C. Color information of the side surface stores information (red, red, red, . . . , blue, and blue) which specifies the value (kind) of the gaming currency C. 
     The information stored in the RFID tag  4503  is information that is electromagnetically readable by the RFID reader  4221 , and the indication information and the color information corresponding to the first currency information of the present embodiment and given to the side surface are optically readable information and correspond to the second currency information of the present embodiment. 
       FIG.  36    is a diagram showing an example of contents of information respectively obtained from one case  4100  by the barcode reader  4228 , the RFID reader  4221 , the infrared-ray camera  4225 , and the visible-light camera  4226 , in the inspection device  4200 . From the RFID reader  4221 , English character strings stored in the RFID tags  4503  built in the plural gaming currencies C are read out. From the infrared-ray camera  4225 , number stings which are indication information indicated on the side surfaces are read out. Also, from the visible-light camera  4226 , colors of the side surfaces are read out. The identification part  4230  analyzes (an image of) the number strings that are read out from the infrared-ray camera  4225  to identify numbers and specify information made from the number strings, and specifies a specific color from an image of the side surfaces read out from the visible-light camera  4226 . 
     Here, although the indication information and the information of the specific color of the side surfaces of the plural gaming currencies C can be obtained according to the aligning order of the gaming currencies C in the case  4100 , the information obtained from the plural RFID tags  4503  cannot be obtained according to the aligning order of the gaming currencies C. That is, it is impossible to specify from which gaming currency C the information of the RFID tag  4503  is obtained. 
     Next, a method of determining pass or fail in the computer  4222  of the inspection device  4200  will be described. As described above, the identification part  4230  specifies the currency information stored in the RFID tags  4503  of the plural gaming currencies C housed in the case  4100 , based on the reading result of the RFID reader  4221 , analyzes the infrared-ray image obtained by the infrared-ray camera  4225  to specify the currency information indicated by the indication information, and analyzes the visible-light image obtained by the visible-light camera  4226  to specify the color of the specific coloring layer  4501 . The determination part  4231 , based on the information, determines authenticity/damage or a number for each value of all of the gaming currencies existing in the case  4100  to determine the pass or fail of the case  4100 . In the following description, the currency information stored in the RFID tag  4503  is referred to as the first currency information, and the indication information and the information of the color of the specific coloring layer  4501  given to the side surface of the gaming currency C is referred to as the second currency information. 
     In a first method of determining pass or fail, as shown in  FIG.  37   , the first currency information and the second currency information in the same gaming currency C are made to be the same information. In an example of  FIG.  37   , the first currency information is information made from the individual identification information and the value information of each gaming currency C, and the same content as this is indicated on the side surface in a form of the indication information as the second currency information. 
     The RFID reader  4221  reads out the first currency information from the RFID tag  4503  of the gaming currency C to output that to the identification part  4230 , the infrared-ray camera  4225  shoots the side surface of the gaming currency C, and the identification part  4230  specifies the second currency information. In this case, in the identification part  4230 , the correspondence relationship between the plural pieces of the first currency information and the plural pieces of the second currency information is unknown. 
     The determination part  4231  compares the plural pieces of the first currency information and the plural pieces of the second currency information obtained by the identification part  4230 , and if they correspond one by one completely, namely, if all of the first currency information are equal to any one of the second currency information without overlapping, determines the plural gaming currencies C housed in the case as passed. The determination part  4231 , if the plural piece of the first currency information and the plural pieces of the second currency information obtained by the identification part  4230  are not completely equal to each other, determines the plural gaming currencies C housed in the case  4100  as failed. 
     As a case that the plural piece of the first currency information and the plural pieces of the second currency information obtained by the identification part  4230  are not completely equal to each other, it is considerable that any one of the gaming currencies C housed in the case  4100  is forged or that the RFID tag  4503  or the side surface of any one of the gaming currencies C is damaged. That is, the determination part  4231  determines the authenticity/damage of all of the gaming currencies C existing in the case  4100 , thereby determining the pass or fail of the plural gaming currencies C housed in the case  4100 . 
     Also, in a second method of determining pass or fail, as shown in  FIG.  38   , the first currency information and the second currency information in the same gaming currency C are the same information. In an example of  FIG.  38   , the first currency information is the value information of each gaming currency C, and to each gaming currency C, the specific color is given as the second currency information to the specific coloring layer  4501  on the side surface. 
     The RFID reader  4221  reads out the first currency information from the RFID tag  4503  of the gaming currency C to output that to the identification part  4230 , the visible-light camera  4226  shoots the side surface of the gaming currency C, and the identification part  4230  analyzes the image to specify the second currency information (the color of the specific coloring layer  4501 ). 
     In this case, in the identification part  4230 , the correspondence relationship between the plural pieces of the first currency information and the plural pieces of the second currency information is unknown. Some of the plural pieces of the first currency information overlap each other, and some of the plural pieces of the second currency information overlap each other. Also, in the first currency information and the second currency information of  FIG.  38   , “r” represents red, “b” represents blue, “y” represents yellow, and “g” represents green, respectively. 
     The determination part  4231  determines the gaming currencies C as passed if the number of the respective specific colors (red, blue, yellow, and green) in the plural pieces of the first currency information obtained by the identification part  4230  is equal to the number of the respective specific colors (red, blue, yellow, and green) in the plural pieces of the second currency information, and determines that as failed if the numbers are not equal to each other. 
     As a case that the number of the respective specific colors in the first currency information is not equal to the number of the respective specific colors in the plural pieces of the second currency information, it is considerable that any one of the gaming currencies C housed in the case  4100  is forged or that the side surface of any one of the gaming currencies C is damaged. That is, the determination part  4231  determines a number for each value of all of the gaming currencies C existing in the case  4100 , thereby determining the pass or fail of the plural gaming currencies C housed in the case  4100 . 
     In the third method of determining pass or fail, as shown in  FIG.  39   , the first currency information and the second currency information in the same gaming currency C are different information. In an example of  FIG.  39   , in the RFID tag  4503  of the gaming currency C, information of English character strings is stored as the first currency information, and on the side surface of the gaming currency C, the indication information of number strings is indicated as the second currency information. 
     The RFID reader  4221  reads out he first currency information from the RFID tag  4503  of the gaming currency C to output that to the identification part  4230 , the infrared-ray camera  4225  shoots the side surface of the gaming currency C, and the identification part  4230  specifies the second currency information. In this case, in the identification part  4230 , the correspondence relationship between the plural pieces of the first currency information and the plural pieces of the second currency information is unknown. 
     In the use management device  4303 , the first currency information and the second currency information are stored in association with the case identification information of the case  4100 . The determination part  4231  compares the plural pieces of the first currency information obtained by the identification part  4230  to the plural pieces of the first currency information associated with the case identification information of the case  4100  stored in the use management device  4303 , and judges whether or not they correspond one by one completely. Also, the determination part  4231  compares the plural pieces of the second currency information obtained by the identification part  4230  to the plural pieces of the second currency information associated with the case identification information of the case  4100  stored in the use management device  4303 , and judges whether or not they correspond one by one completely. 
     The determination part  4231  determines the plural gaming currencies C housed in the case  4100  as passed if the plural pieces of the first currency information obtained by the identification part  4230  correspond to the plural pieces of the first currency information associated with the case identification information of the case  4100  stored in the use management device  4303  one by one completely, namely the plural pieces of the first currency information obtained by the identification part  4230  is equal to any one of the plural pieces of the first currency information associated with the case identification information of the case  4100  stored in the use management device  4303  without overlapping, and if the plural pieces of the second currency information obtained by the identification part  4230  correspond to the plural pieces of the second currency information associated with the case identification information of the case  4100  stored in the use management device  4303  one by one completely, namely, the plural pieces of the second currency information obtained by the identification part  4230  is equal to any one of the plural pieces of the currency information associated with the case identification information of the case  4100  stored in the use management device  4303  without overlapping, and determines the plural gaming currencies C housed in the case  4100  as failed if any one of the plural pieces of the first currency information is not equal to the information stored, or any one of the plural pieces of the second currency information is not equal to the information stored. 
     As a case that any one of the plural pieces of the first currency information is not equal to the information stored, or any one of the plural pieces of the second currency information is not equal to the information stored, it is considerable that any one of the gaming currencies C housed in the case  4100  is forged or that the RFID tag  4503  or the side surface of any one of the gaming currencies C is damaged. That is, the determination part  4231  determines the authenticity/damage of all of the gaming currencies C existing in the case  4100 , thereby determining the pass or fail of the plural gaming currencies C housed in the case  4100 . 
     In the fourth method of determining pass or fail, as shown in  FIG.  40   , the first currency information and the second currency information in the same gaming currency C are different information. In an example of  FIG.  40   , in the RFID tag  4503  of the gaming currency C, information of English character strings is stored as the first currency information, and the specific coloring layer  4501  on the side surface of the gaming currency C is colored in the specific color corresponding to the value as the second currency information. 
     The RFID reader  4221  reads out the first currency information from the RFID tag  4503  of the gaming currency C to output that to the identification part  4230 , the visible-light camera  4226  shoots the side surface of the gaming currency C to output that to the identification part  4230 , and the identification part  4230  analyzes the shot image to specify the specific color that is the second currency information. In this case, in the identification part  4230 , the correspondence relationship between the plural pieces of the first currency information and the plural pieces of the second currency information is unknown. 
     In the use management device  4303 , the first currency information and the second currency information are stored in association with the case identification information of the case  4100 . The determination part  4231  compares the plural pieces of the first currency information obtained by the identification part  4230  to the plural pieces of the first currency information associated with the case identification information of the case  4100  stored in the use management device  4303 , and judges whether or not they correspond one by one completely. Also, the determination part  4231  compares the number of the respective specific colors in the plural pieces of the second currency information obtained by the identification part  4230  to the number of the respective specific colors in the plural pieces of the second currency information associated with the case identification information of the case  4100  stored in the use management device  4303 , and judges whether or not the numbers of the respective specific colors are equal to each other. 
     The determination part  4231  determines the case  4100  as passed, if the plural pieces of the first currency information obtained by the identification part  4230  corresponds to the plural pieces of the first currency information associated with the case identification information of the case  4100  stored in the use management device  4303  one by one completely, and if the number of the respective specific colors in the plural pieces of the second currency information obtained by the identification part  4230  is equal to the number of the respective specific colors in the plural pieces of the second currency information associated with the case identification information of the case  4100  stored in the use management device  4303 , and determines the plural gaming currencies C housed in the case  4100  as failed if any one of the plural pieces of the first currency information is not equal to the information stored or the number of any one of the respective specific colors in the plural pieces of the second currency information is not equal to the information stored. 
     As a case that any one of the plural pieces of the first currency information is not equal to the information stored, or the number of any one of the respective specific colors in the second currency information is not equal to the information stored, it is considerable that any one of the gaming currencies C housed in the case  4100  is forged or that the RFID tag  4503  or the side surface of any one of the gaming currencies C is damaged. That is, the determination part  4231  determines the authenticity/damage and a number for each value of all of the gaming currencies C existing in the case  4100 , thereby determining the pass or fail of the plural gaming currencies C housed in the case  4100 . 
     In the fifth method of determining pass or fail, as shown in  FIG.  41   , the first currency information and the second currency information in the same gaming currency C are different information. In an example of  FIG.  41   , in the RFID tag  4503  of the gaming currency C, individual identification information made from number strings is stored as the first currency information, and to the side surface of the gaming currency C, the value information of the gaming currency C is given in a form of the specific color of the specific coloring layer  4501 . 
     The RFID reader  4221  reads out the first currency information from the RFID tag  4503  of the gaming currency C to output that to the identification part  4230 , the visible-light camera  4226  shoots the side surface of the gaming currency C to output that to the identification part  4230 , and the identification part  4230  analyzes the shot image to specify the specific color that is the second currency information. In this case, in the identification part  4230 , the correspondence relationship between the plural pieces of the first currency information and the plural pieces of the second currency information is unknown. 
     In the use management device  4303 , the correspondence relationship between the first currency information and the second currency information is stored. In an example of  FIG.  41   , the individual identification information which uniquely specifies the gaming currency C and the specific color of the specific coloring layer  4501  on the side surface, namely the value information of the gaming currency C are associated with each other, and when specifying the individual identification information, the value of the gaming currency C can be known. Note that, in this example, the use management device  4303  is not necessary to store the combination of the first currency information and the second currency information for each of case identification information. In other words, in this example, the inspection of the gaming currencies C housed in the case  4100  can be performed without using the case identification information. 
     The determination part  4231  specifies the first currency information corresponding to the first currency information which the identification part  4230  identifies from the first currency information stored in the use management device  4303 , and specifies the second currency information associated with the first currency information, namely the value. The determination part  4231  performs this on all of the first currency information identified by the identification part  4230 , thereby obtaining the number of the respective values in the plural pieces of the second currency information extracted from the use management device  4303  about one case. 
     The determination part  4231  compares the number of the respective values thus obtained to the number of the respective values in the second currency information identified from the identification part  4230  about the case  4100 . The determination part  4231 , if all of the number of the respective values are equal to the information stored, determines the plural gaming currencies C housed in the case  4100  as passed, and if the number of any of the values is not equal to the information stored, determines the plural gaming currencies C housed in the case  4100  as failed. 
     As a case that the number of the respective values in the plural pieces of the second currency information extracted from the use management device  4303  is not equal to the number of the respective values in the second currency information identified from the identification part  4230  about the case  4100 , it is considerable that any one of the gaming currencies C housed in the case  4100  is forged or that the RFID tag  4503  or the side surface of any one of the gaming currencies C is damaged. That is, the determination part  4231  determines the authenticity/damage and a number for each value of all of the gaming currencies C existing in the case  4100 , thereby determining the pass or fail of the plural gaming currencies C housed in the case  4100 . 
     Also, although an illustration is omitted, if the value of the gaming currency is stored as the first currency information and the individual identification information of the gaming currency C is stored as the second currency information, it is possible to determine pass or fail in the same way as above. 
     Although the first to fifth methods of determining pass or fail have been described above, the determination part  4231  may be adopted by combining the above methods of determining pass or fail. Also, the determination part  4231 , in addition to the methods of determining pass or fail mentioned above, if the number of both of the first currency information and the second currency information read out from the plural gaming currencies C housed in the case  4100  are not a predetermined number ( 100  in the present embodiment), may determine the plural gaming currencies C housed in the case  4100  as failed. 
     The first and second methods of determining pass or fail mentioned above are methods of determining pass or fail which can be executed without using information stored in the use management device  4303  installed in the gaming house P, and are suitable for being executed by the inspection device  4200  in the factory F. Although the third to fifth methods of determining pass or fail are methods of determining pass or fail which use information stored in the use management device  4303  installed in the gaming house P, and are suitable for being executed by the inspection device  4200  in the gaming house P, the inspection device  4200  in the gaming house P may adopt the first or second method of determining pass or fail. If all of the inspection devices  4200  in the gaming house P adopt a method of determining pass or fail which does not use information stored in the use management device  4303  like as the first or second methods of determining pass or fail, the use management device  4303  can be omitted. 
     Although the inspection device  4200  in the gaming house P also performs the inspection of the case  4100  housing the gaming currencies C which have been used, in that case, it is possible to adopt the first, second, or fifth method of determining pass or fail in which it is unnecessary to store the information of the gaming currencies that should be housed in the case. 
     Also, in the embodiment described above, the gaming currency C has the individual identification information and/or the value information as the first currency information and/or the second currency information. Here, the individual identification information is information which uniquely specifies each gaming currency C, whereas the value information is information which can overlap with each other in the plural gaming currencies C and can be also said as information (group information) indicating a group to which each gaming currency belongs. The present embodiment, as the group information for the group to which each gaming currency belongs, instead of the value, or in addition to the value, may adopt, for example, information on manufacturing time, manufacturer, and/or usage gaming house of the gaming currency. 
     That is, both of the first currency information and the second currency information may include individual identification information which identifies the gaming currency, both of the first currency information and the second currency information may include group information indicating a group to which the gaming currency belongs, the first currency information may include the individual identification information which identifies the gaming currency and the second currency information may include the group information of the group to which the gaming currency belongs, or the first currency information may include the group information of the group to which the gaming currency belongs and the second currency information may include the individual identification information which identifies the gaming currency. 
       FIG.  42    and  FIG.  43    are diagrams showing examples of pass or fail result display screens displaying the result of the pass or fail determination in the determination part  4231 . These pass or fail result display screens are generated by the computer  4222  based on the result of the pass or fail determination in the determination part  4231 , and are displayed by the display part  4223 .  FIG.  42    shows an example of the display screen in case of pass, and  FIG.  43    displays an example of the display screen in case of fail. 
     As shown in  FIG.  42    and  FIG.  43   , a good/bad results display screen  4800  includes a total detection number  4801  which is the number of the combination of the first currency information and the second currency information which the identification part  4230  reads out from the gaming currencies C, the number of correct gaming currencies C  4802 , and the number of unfair gaming currencies C  4803 . 
     The computer  4222  sets the larger one of the numbers of pieces of the first currency information and the second currency information as the total detection number  4801 . For example, although 100 of the gaming currencies are housed in the case  4100 , if the RFID tag  4503  is not built in one of them, the identification part  4230  specifies 100 pieces of the second currency information from the plural gaming currencies C, but can obtain only 99 pieces of the first currency information. In this case, the computer  4222  sets  100  which is the larger one of pieces of the first currency information and the second currency information as the total detection number  4801 . 
     The computer  4222 , in the case of the first or second method of determining pass or fail, sets the number of the combination of the first currency information and the second currency information that are determined as equal to each other as the number of the correct gaming currencies C  4802 , and sets a number obtained by subtracting the number of the correct gaming currencies C from the total detection number  4801  as the number of the unfair gaming currencies C  4803 . 
     The computer  4222 , in the case of the third or fourth method of determining pass or fail, sets the smaller one of the numbers of pieces of the first currency information for which the correspondence relationship with the first currency information stored in the use management device  4303  is confirmed, and of the second currency information for which the correspondence relationship with the second currency information stored in the use management device  4304  is confirmed, as the number of the correct gaming currencies C  4802 , and sets the number obtained by subtracting the number of the correct gaming currencies C from the total detection number  4801  as the number of the unfair gaming currencies C  4803 . 
     The computer  4222 , in the case of the fifth method of determining pass or fail, sets the number of pieces of the second currency information for which the correspondence relationship with the second currency information stored in the use management device  4303  as the number of the correct gaming currencies C  4802 , and sets the number obtained by subtracting the number of the correct gaming currencies C from the total detection number  4801  as the number of the unfair gaming currencies C  4803 . 
     The good/bad results display screen  4800  includes the currency information display part  4804  displaying the currency information which the identification part  4230  reads out from the gaming currencies C. In the currency information display part  4804 , if the currency information stored in the use management device  4303  is read out, or if the first currency information is equal to the second currency information, the currency information is displayed in color, and the currency information which is stored in the use management device  4303  but is not read out is displayed in white (refer to  FIG.  43   ). 
     Also, in the good/bad results display screen  4800 , if the currency information which is not stored in the use management device  4303  is read out, or if the first currency information is not equal to the second currency information, the currency information is displayed outside the currency information display part  4804  as unfair currency information  4805 . 
       FIG.  44    is a diagram indicating a modification of an RFID antenna  4224  of an inspection device  4200 . Note that illustrations of an arm  4227 , infrared-ray camera  4225 , and a visible-light camera  4226  are omitted. In the above embodiments, although the RFID antenna  4224  is built in right and left side walls  4211 , the RFID antenna  4224  may be built in a bottom part  4213 . Also in this case, the RFID antenna  4224  is placed inside the bottom part  4213  in a spiral manner. 
       FIG.  45    is a side view showing a gaming currency C′ in a modification. Although in the gaming currency C in the above embodiments, the specific coloring layer  4501  is sandwiched by the common coloring layers  4502 , in an example of  FIG.  45   , the gaming currency C′ is comprised of the common coloring layers  4502  at the center and the specific coloring layers  4501  at both sides thereof (upper and lower). In an example of  FIG.  45   , individual identification information represented by seven-digits number strings is written (printed) as code information  4505 ′ at the side surface of the gaming currency C′. In an example of  FIG.  45   , the code information  4505 ′ being written information is written in a central common coloring layer  502 . The code information  4505 ′ in this case can represent seven kinds of article information among ten kinds of article information. 
     Further, both of the code information  4505  represented by whether there is indication m that is described for the currency for gaming currency C in the above embodiment, and the code information  4505 ′ in the number strings that is illustrated in  FIG.  45    may be written at the side surface of the gaming currency C. In this case, the code information  4505  with the indication m and the code information  4505 ′ in the number strings may be printed with different inks. For example, the code information  4505  with the indication m may be printed with infrared-ray responsive inks, and the code information  4505 ′ in the number strings may be printed with ultraviolet-ray responsive inks. In this case, the infrared-ray camera and the ultraviolet-ray camera are prepared in order to shoot the side surface of the gaming currency C, the code information  4505  with the indication m may be read using the infrared-ray camera, and the code information  4505 ′ in the number strings may be read using the ultraviolet-ray camera. 
       FIG.  46    is a side sectional view of the gaming currency C″ in another modification. The gaming currency C″ comprises a multi-layer structure where different plastic layers with plural colors are stacked, at least specific coloring layer (colored layer)  4501  is provided at the middle, and common coloring layers (white color or lighter-color layers)  4502  are stacked at both sides of the middle specific coloring layer  4501 . Note that it is preferable for colors of the common coloring layers  4502  to be thinner than color of the specific coloring layer  4501 . As such, in the gaming currency C″, the multi-layer structure where the specific coloring layer  4501  is provided at the middle, and the common coloring layers  4502  are stacked at both sides of the middle specific coloring layer  4501  can identify a kind of the gaming currency C″ (10 points, 20 points, 100 points, 1000 points, and the like) by forming a striped pattern in a stacking direction at the side surface, and changing the color of the specific coloring layer  4501  (red, green, yellow, blue and the like). 
       FIG.  47    is a perspective view of the stacked gaming currencies C″,  FIG.  48    is a side view of the gaming currency C″, and  FIG.  49    is a plan view of the gaming currency C″. As shown in  FIG.  47   , in the gaming currencies C″, a printing  4507  (e.g. 100 points) representing a kind (value) of the gaming currency C″ is made at surfaces of the common coloring layers  4502  (top surface and lower surface), a transparent layer  4504  is provided at the most outer layer, and at least five-layer structure is made with thermal compression between layers. These gaming currencies C″ is formed by using long and thin elongated plastic materials, forming a state (e.g. five-layer structure) thermal compressed and attached between the layers (specific coloring layer  4501 , common coloring layer  4502 , and transparent layer  4504 ), and then punching them into a circular form, rectangular form, or the like with press etc. When punching by pressing, R machining (a rounded corner) is applied at an edge of the most outer transparent layer  4504  by designing the dimensions of die and punch for a mold for punching. 
     Further, in the gaming currency C″, the indication m″ is provided with UV inks or carbon black inks at the surface of the common coloring layer  4502 . The indication m″ represents the authenticity of the gaming currency C″, becomes visible by radiation of ultraviolet-ray light (or infrared-ray light), and represents correct one with the combination of the shape and number. Although the most outer layer is thermal compressed or coated (applied) with the transparent layer  4504  to cover the printing  4507  and indication m′, embossing is made on the transparent layer  4504  to avoid adhesion of the gaming currencies C″ each other. 
     The R machining (R) is performed at the edge of the most outer transparent layer  4504  where the printing  4507  (e.g. 100 points) is made to avoid that the surface of the common coloring layers  4502  is deform to appear in the side surface in the punching process. Also, a sharp edge of the gaming currency C″ is prevented from damaging a remaining hand and other gaming currencies C″. 
     The specific coloring layer  4501  may be formed with plural layers (three layers in  FIG.  46   ) colored by a specific color as shown in  FIG.  46   . Since the plural layers colored by the specific color are thermal compressed each other, the three-layer structure is not visible as shown in  FIG.  46   , and  FIG.  26    represents three layers of the specific coloring layers  4501  for description. Further, the hollowing B is partially provided in the middle layer of the three layers of the specific coloring layers  4501 , and the RFID tag  4503  is built therein. 
     As shown in  FIG.  26   ,  FIG.  45   , and  FIG.  46   , the gaming currencies C, C′ and C″ include a stacked multi-layer structure, form clear striped pattern at the side surface in the stacking direction, and allow easy and accurate measurement of colors (kind of the gaming currency) and numbers with image analysis, comparing to the conventional chip.  FIG.  50    is a diagram indicating an example of an image obtained by shooting the stacked gaming currencies. As shown in  FIG.  50   , the specific coloring layer  4501  can be clearly identified by shooting the side surface of the gaming currency C with the visible-light camera  4226 . Further, the images can be analyzed and determined more accurately by using a computer or controlling system utilizing an artificial intelligent technique, and a deep learning (structure) technique in the image analysis. Since the computer or controlling system utilizing the artificial intelligent technique, and the deep learning (structure) technique are known and available for one skilled in the art, the detailed description is omitted. 
     As stated above, the case  4100  is stamped with a stamp after housing a predetermined number of the gaming currencies C. The stamp is broken if it is opened so as to take out the gaming currencies housed. The detection device  4200  may comprise a detection part for detecting the unbroken stamp attached to the case  4100 . The detection part may detect the stamp optically or magnetically. In this case, the determination part  4231  determines that the plural gaming currencies C housed in the case  4100  are failed if the unbroken stamp is not detected by the detection part. 
     In the above embodiment, as shown in  FIG.  30   , all components of the inspection device  4200  are arranged in one device, they may be arranged in a distribution manner. For example, some or all of the computer  4222 , the display part  4223 , and the communication part  4224  may be implemented by a personal computer connected to the inspection device  4200 . The components arranged in the distribution manner may be communicatively connected with wired or wireless manner, and may be connected via a network such as the Internet. 
     Further, as shown in  FIG.  51    and  FIG.  52   , the infrared-ray camera  4225  and/or visible-light camera  4226 , and the arm  4227  may be connected to the computer  4222  separately from the inspection device  4200 .  FIG.  51    shows an example in which either of the infrared-ray camera  4225  or the visible-light camera  4226  is provided separately from the inspection device  4200 , and  FIG.  52    shows an example in which the infrared-ray camera  4225  is provided separately from the inspection device  4200  and the visible-light camera  4225  is provided integrally with the inspection device  4200 . Note that an ultraviolet-ray camera may be provided as a third camera with an ultraviolet-ray lamp in addition to the infrared-ray camera  4225  and the visible-light camera  4226 , and any cameras in  FIG.  51    and  FIG.  52    may be the ultraviolet-ray camera with the ultraviolet-ray lamp. 
     In the above embodiment, the gaming currency C includes the currency information stored in the RFID tag  4503 , and the code information  4505  as currency information written at the side surface. Also, although the specific color of the specific coloring layers  4501  at the side surface are considered as the currency information indicating values of the gaming currency C, and one gaming currency C has these three types of the currency information, the present embodiment is not limited to the above, and the gaming currency C may have only two types of the currency information among them. As long as the gaming currency C has two types of the currency information, the first to fifth pass or fail determination methods can be performed. 
     Also, although the first to fifth pass or fail determination methods use two types of the currency information, the determination part  4231  may perform the pass or fail determination using the three types of the currency information if the gaming currency C has the three types of the currency information. 
     Although the above embodiment describes an example in which the display part  4223  is configured with the liquid crystal panel, the display part  4223  may be a lamp indicating the pass or fail only, or a lamp displaying digitally the total detection number  4801 , the number of correct gaming currencies C  4802 , and the number of unfair gaming currencies C  4803  only. 
     The determination part  4231  in the above embodiment can identify the number of respective values of the plural gaming currencies C housed in the case  4100 . Here, the determination part  4231  further may calculate the total amount of values of the plural gaming currencies C housed in the case  4100  based on the number of the respective values. The calculated total amount may be displayed on a good/bad results display screen (reference to  FIG.  42    and  FIG.  43   ) displayed in the display part  4233 . 
     A fifth embodiment relates to an inspection system and an inspection device for inspecting a gaming currency, more specifically, relates to the inspection system and the inspection device for inspecting the gaming currency including a built-in radio tag or counting the number of the gaming currencies. 
     The gaming currency including the built-in radio tag for storing identification information and kind information is known (e.g. Japanese Patent Laid-Open No. 2008-246103). 
     Japanese Patent Laid-Open No. 2008-246103 discloses the gaming currency having a configuration for avoiding the radio tag from being brought out easily. This implements a configuration in which fault in the radio tag hardly occurs. 
     However, in the case of reading the number of the gaming currencies with the radio tag disclosed in Japanese Patent Laid-Open No. 2008-246103, the number of the gaming currencies is calculated based on the read radio tag information, and if the radio tag built in the gaming currency is broken or the radio tag is not built in the gaming currency, there is a problem in which the currency information cannot be obtained, and the actual number of the gaming currencies and the number of the gaming currencies calculated by reading the radio tag are different. 
     The present embodiment has the objective for providing an inspection system and an inspection device for allowing to inform that the radio tag is destroyed. 
     The inspection system in a first aspect of the fifth embodiment is an inspection system for inspecting gaming currencies including a built-in radio tag for storing currency information and having colors or representations representing values at an outer surface, the gaming currencies being housed in a case at a condition on which the maximum housing number is limited, wherein the gaming currencies are housed in the case capable of housing the gaming currencies stacked in a thickness direction and in a column, the inspection system comprising: a reading device for reading the radio tag of the gaming currency in the case and obtaining the currency information of the gaming currency; and a determination part for comparing the currency information obtained by the reading device to a maximum housing number of the case itself, and determining the gaming currency in the case as abnormal when the number of the gaming currencies obtained from the currency information that is obtained by the reading device is different from the maximum housing number.

     Further, the physical information is an optically-obtained number or height, or a measured and obtained weight. 
     Further, the inspection system has further an information database of the radio tag that information of the radio tag built in the gaming currency can be referred, and the determination part may have a configuration of checking the currency information of the gaming currency read by the reading device with the information database of the radio tag and capable of detecting the gaming currency to be inspected as abnormal. 
     Further, the determination part may have functions of, if determining that there is any abnormal gaming currency of the gaming currencies in the case, comparing the information of the radio tags of all gaming currencies in the case to the pre-recorded information database of the radio tag, and identifying that there is the abnormal radio tag not present in the information database of the radio tag. 
     Further, the determination part may have functions of, if determining that there is any abnormal gaming currency of the gaming currencies in the case, identifying that in any gaming currencies in the case, there is the abnormal gaming currency for which the information cannot be obtained from the radio tag. 
     Further, the determination part may have functions of analyzing the information of the radio tag obtained by the reading device, and sending a signal when there are in the case two or more gaming currencies for which the information obtained from the radio tags is the same. 
     Further, the information database of the radio tag is an information database of the radio tag of gaming currencies stored and used in a gaming house, and the determination part may have functions of analyzing the information of the radio tag obtained by the reading device and sending a signal when the information obtained from the radio tag is the same as the information of the radio tag for the gaming currency that is present in other places in the gaming house. 
     The inspection device in a second aspect of the fifth embodiment is an inspection device for inspecting gaming currencies including a built-in radio tag for storing currency information and having colors or representations representing values at an outer surface, the inspection device comprising: an inspection table on which the gaming currencies stacked in a thickness direction and in a column can be inspected at a condition on which the maximum stacking number is limited; a reading device for reading the radio tags of the gaming currencies in the column and obtaining the currency information of the gaming currencies in the column; and a determination part for comparing the currency information obtained by the reading device to a maximum stacking number of the inspection table itself and determining an abnormal gaming currency present on the inspection table when the number of the gaming currencies obtained from the currency information that is obtained by the reading device is different from the maximum stacking number. 
     Further, the determination part may have functions of determining and outputting that there is any abnormal gaming currency of the gaming currencies present on the inspection table when the currency information of the gaming currency obtained by the reading device is different from the physical information of the gaming currency. 
     Further, the physical information may be an optically-obtained number or height, or a measured and obtained weight. 
     Further, the inspection device further includes an information database of the radio tag that information of the radio tag built in the gaming currency can be referred, and the determination part may have a configuration of capable of checking the currency information of the gaming currency read by the reading device with the information database of the radio tag and detecting the gaming currency to be inspected on the inspection table as abnormal.

       FIG.  63    is a diagram for explaining an example of a usage aspect of the inspection system  1  together with the distribution of the gaming currencies C. The gaming currencies C are manufactured by a manufacturing device  5301  in a factory F (s1), and respective 100 currencies are housed in the case  5100  (s2). The case  5100  is stamped with a stamp seal in the factory F after housing the gaming currencies C. Also, in the case  5100 , the barcode BC indicating the case identification information for uniquely specifying the case  5100  is affixed to the side surface (s3). 
     At that time, in the manufacture management device  5302  in the factory F, the case identification information of the barcode BC affixed to the case  5100  is input (s4). Also, the case  5100  housing the gaming currencies C is subjected to the inspection device  5200  to read currency information (the details will be described below) given to the gaming currencies C, and the inspection of pass or fail is performed. Then, the currency information read from the gaming currencies C housed in the case  5100  is sent to the manufacture management device  5302  (s5), and associated with the case identification information by the manufacture management device  5302 . Note that the manufacture management device  5302  may be a personal computer. 
     The case  5100  which has been passed in the inspection device  5200  in the Factory F is transported from the factory F to the gaming house P (s6). The case  5100  is firstly stored in a repository R in the gaming house P (s7). The inspection device  5200  is installed in the repository R, and the case  5100  delivered from the factory F is inspected by the inspection device  5200 . 
     On the other hand, the case identification information and the currency information associated therewith are sent from the manufacture management device  5302  in the factory F to the information database  5303  in the gaming house P. The information database  5303  comprises a storage part which obtains the case identification information and the currency information associated with that from the manufacture management device  5302 , for each of the plural cases  5100  housing the gaming currencies C, and stores them for each case  5100 . Note that the information database  5303  may be a personal computer. 
     In the inspection by the inspection device  5200  in the repository R, the inspection is performed using the information stored in the information database  5303 . The case  5100  which has been passed in the inspection in the repository R is carried to a game table T (s9), or is carried to a cashier CA (s10). The game table T and the cashier CA also comprise the inspection device  5200  respectively, and the case  5100  housing the gaming currencies C is inspected by the inspection device  5200  while being stamped. In the game table T and the cashier CA, the inspection of the case  5100  housing the gaming currencies C which have been used is also performed, and the inspection devices  5200  are used for the inspection. In the inspection by three inspection devices  5200  in the gaming house P, the case identification information and the currency information associated therewith sent from the manufacture management device  5302  and stored in the information database  5303  are referred to. 
     Also, in the above embodiment, the gaming currency C has the identification information and/or the value information as radio tag information. Here, the identification information is information which uniquely specifies each gaming currency C, whereas the value information is information which can overlap with each other in the plural gaming currencies C, and can be also said as information (group information) indicating a group to which each gaming currency belongs. The present embodiment, as the group information for the group to which each gaming currency belongs, instead of the value, or in addition to the value, may adopt, for example, information on manufacturing time, manufacturer, and/or usage gaming house of the gaming currency. 
     That is, the radio tag information may include the identification information for identifying the gaming currency, and the group information indicating the group to which each gaming currency belongs. 
     As stated above, the case  5100  is stamped with the stamp seal after housing a predetermined number of the gaming currencies C. The stamp is broken if it is opened so as to take out the gaming currencies housed. The detection device  5200  may comprise a detection part for detecting the unbroken stamp attached to the case  5100 . The detection part may detect the stamp optically or magnetically. In this case, the identification contents determination part  5231  determines that the plural gaming currencies C housed in the case  5100  are failed if the unbroken stamp is not detected by the detection part. 
     In the above embodiment, as shown in  FIG.  542   , all components of the inspection device  5200  are arranged in one device, they may be arranged in a distribution manner. For example, some or all of the determination part  5222 , the display part  5223 , and the communication part  5224  may be implemented by a personal computer connected to the inspection device  5200 . The components arranged in the distribution manner may be communicatively connected with wired or wireless manner, and may be connected via a network such as the Internet. 
     In the above-mentioned embodiment, such an example is explained that the display part  5223  is constituted by a liquid display panel. The display part  5223  may be a lamp for simply displaying only pass/fail results, and may be a lamp for digitally displaying only the total detection number  5801 , the number  5802  of correct gaming currencies C, and the number  5803  of unfair gaming currencies C. 
     The identification contents determination part  5231  in the above-mentioned embodiment can specify the number of the respective values of the plural gaming currencies C housed in the case  5100 , as described above. Furthermore, the identification contents determination part  5231  may calculate a total amount of the values of the plural gaming currencies C housed in the case  5100  based on the number of the respective values. The calculated total amount may be displayed on a pass/fail results display screen displayed at the display part  5233  (see  FIGS.  60  and  61   ). 
     As described above, conventionally, an inspection system for inspecting authenticity of the gaming currency by embedding an RF tag (radio tag) inside the gaming currency is known. Such an inspection system is configured to record detection in a recording device, or issue alarms by an alarm device, when the gaming currency (typically, a forged gaming currency, or a gaming currency whose RF tag is broken, hereinafter referred to as “unfair gaming currency”) whose RF tag cannot be read, or whose information read from the RF tag is not predetermined information, is detected. 
     However, the gaming currencies are circulated between dealers (casino) and players. It is inconvenient that it is unknown when and from which player the unfair gaming currency is delivered to the casino, when the casino inspects the holding gaming currencies and finds the unfair gaming currency. 
     Therefore, in this embodiment, an inspection system that can detect the unfair currency, immediately when or as soonest as the unfair currency is delivered from the player to the dealer, is provided. 
     Thus, an inspection system according to one aspect of the present embodiment is an inspection system for inspecting a gaming currency in which an RF tag is built, comprising: a housing means for housing gaming currencies of a dealer in a casino game; an RF reading means for reading the RF tags of the plural gaming currencies housed in the housing means; a detection means for detecting at least the number of the plural gaming currencies housed in the housing means by a method other than an RFID at constant time intervals or always; and an alarm means for generating an alarm when the number of the gaming currencies whose RF tags are read by the RF reading means is not equal to the number of the gaming currencies detected by the detection means. 
     By this configuration, the RF reading means detects the number of the gaming currencies housed in the housing means, and the detection means detects the number of the gaming currencies housed in the housing means by a method other than the RFID at constant time intervals or always. When the numbers are not equal to each other, the alarm means generates the alarms. Therefore, immediately when the unfair gaming currencies are housed in the housing means, or within a constant time from when the unfair gaming currencies are housed in the housing means, the alarm means can generate the alarms. Also, the RF reading means may read the RF tag at constant time intervals or always. 
     The detection means may detect whether or not the number of the gaming currencies housed in the housing means is changed. The alarm means may compare the number of the gaming currencies detected by the detection means to the number of the gaming currencies whose RF tags are read by the RF reading means, and determine whether the numbers are equal to each other, when the change of the number of the gaming currencies is detected by the detection means. 
     When the dealer collects the gaming currencies from players in a casino game, the housing means may be used to house the collected gaming currencies. By this configuration, when the dealer collects the gaming currencies from the players, the unfair currencies can be detected. 
     The detection means may detect existence of each of the plural gaming currencies housed in the housing means by a method other than the RFID. 
     The housing means may be configured to stack and house the plural gaming currencies in a predetermined stacking direction, and the detection means may have plural photosensors arranged in the stacking direction to detect each of the plural gaming currencies stacked and housed in the housing means. 
     The housing means may have a groove extending in the stacking direction, the plural photosensors may be arranged in plural lines along the stacking direction, and the gaming currencies may be detected by the photosensors arranged in different lines in an order of stacking. 
     The housing means may have plural lines of grooves extending in the stacking direction, and the RF reading means may read the RF tags for one or plural lines of the grooves. 
     The detection means may include plural photosensors for detecting each of the plural gaming currencies housed in the housing means. 
     The detection means may detect the number of the plural gaming currencies housed in the housing means by optically reading the plural gaming currencies housed in the housing means. Such detection means may be, for example, an optical scanner for scanning the stacked gaming currencies in a stacking direction. 
     The housing means may house the plural gaming currencies such that the plural gaming currencies are stacked from a predetermined reference position, and the detection means may detect the number of the plural gaming currencies housed in the housing means by measuring a distance from a predetermined monitoring position to a gaming currency of the gaming currencies, the gaming currency being furthest away from the predetermined reference position. 
     By this configuration, the number of the plural gaming currencies stacked in the housing means may be detected according to the height (length) in the stacking direction of the plural gaming currencies stacked in the housing means. Such detection means may be, for example, a distance sensor that is installed at a tip in the stacking direction, and measures a distance from a reference position to the furthest away gaming currency. 
     The RF reading means may read RF tags at a first time interval, such that the RF tags of plural gaming currencies are read within the first time interval from when other gaming currencies are housed in the housing means, the plural gaming currencies including the other gaming currencies, and the detection means may detect the number of the plural gaming currencies housed in the housing means at a second time interval, such that the number of the plural gaming currencies are detected within the second time interval from when the other gaming currencies are housed in the housing means, the plural gaming currencies including the other gaming currencies. 
     By this configuration, when new gaming currencies are added to the housing means, the RF tags are read within the first time interval and the number is detected within the second time interval. So, from when the new gaming currencies are added to the housing means at least until any longer one of the first time interval and the second time interval, the reading of the RF tags and the detection of the number by the means other than the RFID are completed, and alarms can be generated when needed. Therefore, the dealer houses the gaming currencies collected from the players according to the results of a game in the housing means, and can inspect the gaming currencies immediately after the gaming currencies are collected from the players. 
     The inspection system according to another aspect of the present embodiment is an inspection system for inspecting a gaming currency used for a game played on a table, comprising a housing means installed on the table, the housing means housing plural gaming currencies, the number of the plural gaming currencies being increased or decreased for each game, and an inspection means for inspecting the gaming currencies, the number of the gaming currencies being increased or decreased for each game in the housing means. 
     The inspection system according to further another aspect of the present embodiment is an inspection system for inspecting a gaming currency in which an RF tag is built, comprising: a housing means capable of housing a predetermined number of gaming currencies; an RF reading means for reading RF tags of the plural gaming currencies housed in the housing means; and an alarm means for generating an alarm when the number of the gaming currencies whose RF tags are read by the RF reading means is not equal to the predetermined number. 
     By this configuration, while the number of the gaming currencies that can be housed in the housing means are housed, the RF tags are read by the RF reading means and the number of the tags is compared to the number that can be housed, so that the gaming currencies whose RF tags cannot be read are detected and the alarms can be generated. 
     The inspection system may further comprise a dummy currency in which the RF tag is built, the dummy currency being to be housed in the housing means together with the gaming currencies, such that the predetermined number is reached in total with the gaming currencies, when the number of the gaming currencies is below the predetermined number. 
     By this configuration, when the gaming currencies of the number that does not reach the number that can be housed by the housing means (housable number) are inspected, dummy currencies of the shortage number are housed in the housing means, so that the alarms can be generated when an ideal value of the number of the RF tags to be read by the RF reading means is not equal to the housable number. 
     The inspection system in the present embodiment is not limited to an inspection system for inspecting gaming currencies, and can be applied as an inspection system for inspecting an arbitrary valuable, in which an RF tag is built. In this case, an inspection system for a valuable comprises: a valuable to which a unique ID that is individually identifiable is attached; a table on which the valuable is used; a tray for holding the valuable on the table; a determination means for specifying the number of valuables held on the tray using each unique ID; a detection means for shooting the valuables on the table including at least the tray to create an image, and detecting at least the number of the valuables based on the image; a storage means for storing the number detected by the detection means; and an inspection means for inspecting a relationship between the number determined by the determination means and the number detected by the detection means. 
     The inspection system in the present embodiment is not limited to an inspection system for inspecting gaming currencies, and can be applied as an inspection system for inspecting an arbitrary object, in which an RF tag is built. In this case, the inspection system comprises: an RF reading means for reading the RF tag of the object located at a predetermined place; a detection means for detecting at least the number of the objects located at the predetermined place in a method other than an RFID; and an alarm means for generating alarms when the number of the objects whose RF tag is read by the RF reading means is not equal to the number detected by the detection means.

The RF antenna  6712  is installed at an inner part or a bottom part of the gaming currency tray  671  corresponding to each groove  6171 . Also,  FIG.  65    shows only four grooves; however, other grooves  6171  are similar. 
     In the example of  FIG.  65   , one RF antenna  6172  is installed to one groove  6171 . The RF antenna  6172  is radio-communicated with the RF tag built in the gaming currency C housed in the corresponding groove  6171 , and read the RF information from the RF tag. An electric wave shielding wall may be provided between the adjacent grooves  6171 , so that each RF antenna  6172  does not read the RF tag of the gaming currency C housed in the next groove  6171 . 
       FIG.  66    is an enlarged plane view and a front-direction cross section view of the groove  6171 . The gaming currencies C are stacked in a longitudinal direction of the groove  6171  and housed in the groove  6171 . In the example of  FIG.  66   , 40 gaming currencies C can be housed in one groove  6171 . 
     Plural photosensors  6713  are embedded on the right and left sides of an inner wall with a semicircular cross section, so that sensing faces are flush with the inner wall. The photosensors  6713  are reflection-type photosensors, and detect the gaming currencies C when the sensing faces are blocked with the gaming currencies C by housing the gaming currencies C in the groove  6171 . 
     The plural photosensors are aligned on the right and left sides of the inner wall at a pitch of thickness of the 2 gaming currencies C. In this example, as described above, 40 gaming currencies C can be housed in one groove  6171 . So, 20 photosensors  6173  are provided on the right side, and 20 photosensors  6173  are provided on the left side. 
     The line of the plural photosensors  6173  on the right side is displaced from the line of the plural photosensors  6173  on the left side by the thickness of one gaming currency C. Therefore, the plural gaming currencies C stacked and housed in the groove  6171  are detected by the photosensors  6173  arranged in different lines in an order of stacking. Concretely, the gaming currency C housed a lowermost position of the groove  6171  is detected by the photosensor  6173  at a lowermost part on the right side, the second gaming currency C from the bottom is detected by the photosensor at a lowermost part on the left side, the third gaming currency C from the bottom is detected by the second photosensor  6173  from the bottom on the right side, and the fourth gaming currency C from the bottom is detected by the second photosensor  6173  from the bottom on the left side. In this manner, right side photosensors  6183  and left side photosensors  6173  alternately detect the gaming currencies C sequentially from the bottom. 
     In this manner, the plural photosensors  6173  are alternately arranged in the different lines, so that the plural photosensors  6173  for reading the plural gaming currencies C stacked and housed in the groove  6171  in the thickness direction one by one can be arranged. 
       FIG.  67    is a diagram indicating an entire configuration of the inspection system. As shown in  FIG.  67   , an inspection system  600  comprises: an RF reader  6100  having an RF antenna  6172 ; plural photosensors  6173 ; an inspection/alarm part  6200  connected to the RF reader  6100  and the plural photosensors  6173 ; and a storage part  6300  connected to the inspection/alarm part  6200 . The inspection/alarm part  6200  is configured by a computer including a processor and a memory, and is realized by processor&#39;s executing an inspection/alarm program in the present embodiment. 
     The RF reader  6100  receives electric waves from the RF tag of the gaming currency C with the RF antenna  6172 , and reads information (tag information) stored in the RF tag. The RF reader outputs the read tag information to the inspection/alarm part  6200 . As shown in  FIG.  65   , the inspection system  600  comprises plural RF antennas  6172 . The plural RF antennas  6172  may be connected to one RF reader  6100 , and the plural RF readers  6100  may be provided corresponding to the plural RF antennas  6172 . 
     The plural photosensors  6173  are respectively connected to the inspection/alarm part  6200 , and transmits sensing information to the inspection/alarm part  6200 . The sensing information of each photosensor  6173  is information indicating existence of the gaming currency C. 
     The inspection/alarm part  6200  compares the number of the tag information read by the RF reader  6100  with the number of detection information of the gaming currencies C obtained from the plural photosensors  6173 . In this case, the inspection/alarm part  6200  determines whether the tag information is true or false, and may compare only the number of the tag information determined as true with the number of the detection information of the photosensors  6173 . 
     When the true RF tags are built in all of the plural gaming currencies housed in the gaming currency tray  617 , the number of the tag information read by the RF reader  6100  must be equal to the number of the gaming currencies C detected by the photosensors  6173 . Thus, the inspection/alarm part  6200  determines whether or not the numbers are equal to each other, and generates alarms when the numbers are not equal to each other. 
     The generated alarms are outputted in a system that can be sensed by a person with alarm means (not shown). For example, when the alarm means is a loudspeaker, the inspection/alarm part  6200  generates signals for outputting predetermined alarm sounds from the loudspeaker as alarms. When the alarm means is a lamp, the inspection/alarm part  6200  generates signals for lighting the lamp as alarms. 
     The RF reader  6100  reads the tag information at a predetermined time interval (for example, one-second interval). Also, the photosensor  6173  executes detection at a predetermined time interval (for example, 2-second interval). The RF reader  6100  and the photosensor  6173  may always execute reading and detection. 
     Also, the RF reader reads the tag information at a predetermined time interval or always, and the inspection/alarm part  6200  determines whether or not there is a change of the plural pieces of the read tag information. When there is a change, detection may be executed by the photosensor  6173  according to the control of the inspection/alarm part  6200 . On the other hand, the gaming currencies C are detected by the plural photosensors  6173  at a predetermined time interval or always, and the inspection/alarm part  6200  determines whether or not there is a change of the number of the detected gaming currencies C. When there is a change, the tag information may be read by the RF reader  6100  according to the control of the inspection/alarm part  6200 . 
     When alarms are generated by the inspection/alarm part  6200 , the alarm means immediately outputs alarms. Therefore, within a predetermined time from when and immediately after the unfair gaming currency is housed in the gaming currency tray  617 , the alarms are outputted. Thus, it can be grasped from which player playing on the table at that time the unfair currency is delivered. Also, the game is once stopped, so that the unfair gaming currency can be prevented from being used furthermore. In some cases, the player who delivers the unfair gaming currency can be specified among players playing on that table. 
     The inspection/alarm part  6200  records the results of inspection (comparison) and the generated alarms together with the information of date and time, in the record part  6300 . 
       FIG.  68    is a plane view indicating the other example of the gaming currency tray. In the example of  FIG.  68   , in addition to plural grooves (stock grooves)  6171  in a vertical direction for housing the gaming currencies C, horizontal grooves (collecting grooves)  6174  used to house the gaming currencies C the dealer collects from the players are provided above them. Also, in the example of  FIG.  68   , the photosensor  6173  is not provided on a stock groove  6171 , the photosensors  6173  are embedded in a collection groove  6174  at an arrangement similar to  FIG.  66   , and an RF antenna  6172  (not shown) is embedded under the collection groove  6174 . 
     The number of the gaming currencies C housed in the collection groove  6174  is increased or decreased per game. Accordingly, the collection groove  6174  is provided with the photosensor  6173  and the RF antenna  6172 , so that an interval of inspection is made sufficiently short. The gaming currencies C immediately after collected from the players can be inspected per game. When the unfair gaming currency is detected, a player holding it can be specified, or a game can be stopped. Also, when the gaming currencies C of not less than a constant number or a housable number are housed in the collection groove  6174 , some or all of them may be transferred to the stock groove  6171 . 
       FIG.  69    is a plane view indicating the further example of the gaming currency tray. In the example of  FIG.  69   , the collection groove  6175  is provided at a right end in a vertical direction. Then, the photosensor  6173  and the RF antenna  6172  (not shown) are provided on the collection groove  6175 . 
       FIG.  70    is a plane view indicating the further example of the gaming currency tray. In the example of  FIG.  70   , grooves in the vertical direction are divided into two stages of upper and lower grooves  6176 ,  6177  that can respectively house 20 gaming currencies C. Each groove  617  can house 20 gaming currencies C. As is similar to the example of  FIG.  64   , photosensors  6173  are alternately provided on each groove  617  on both of right and left sides. In the gaming currency tray  617  in this example, the number of the stacked gaming currencies C is small, so that displacement between the stacked and housed gaming currencies C and the photosensor  6173  can be avoided from being large. 
     In the examples of  FIGS.  69  and  70   , the photosensor  6173  and the RF antenna  6172  are provided on the collection groove as well, so the gaming currencies C can be inspected immediately after collection. 
       FIG.  71    is a diagram indicating another configuration of an RF antenna. In the above-mentioned sixth embodiment, one RF antenna is provided on one groove  6171 . As shown in FIGS.  71 , one RF antenna  6172  may be configured and arranged to read the RF tags of the gaming currencies C housed in the plural grooves  6171 . 
     In the above-mentioned sixth embodiment, when inspecting the gaming currencies C, it is determined whether or not the number of the gaming currencies C whose RF tags are read by the RF reader  6100  is equal to the number of the gaming currencies C detected by physical means other than RFID, so as to detect the unfair gaming currency that does not have an RF tag or whose RF tag is broken. Then, the photosensors  6173  for detecting the existence of the gaming currencies one by one is used as means for detecting the number of the gaming currencies C physically with means other than RFID. 
     However, means for physically detecting the number of the gaming currencies C with means other than RFID is not limited to plural photosensors. Hereinafter, the other example of the detection means will be explained. 
       FIG.  72    is a diagram indicating one groove of a gaming currency tray using a line sensor as detection means. As shown in  FIG.  72   , a slit  6178  extending in a longitudinal direction of the groove  6171  is formed at a bottom of an inner wall of the groove  6171 , and a line sensor  6179  is provided along the slit  6178  below the slit  6178 . A pixel pitch in the longitudinal direction of the line sensor  6179  is set smaller than the thickness of the gaming currency C (the pixel number in the longitudinal direction of the line sensor  6179  is set sufficiently larger than the housing number of the gaming currencies C of the groove  6171 ). 
       FIG.  73    is a diagram indicating an entire configuration of an inspection system  600  in the example of  FIG.  72   . The line sensor  6179  is connected to the inspection/alarm part  6200 . The line sensor  6179  acquires a line image by picking up an image. The line sensor  6179  outputs the acquired line image to the inspection/alarm part  6200 . The inspection/alarm part  6200  detects the number of the gaming currencies C housed in the groove  6171  by determining to where there are gaming currencies C from the bottom, based on the line image. 
     The RF antenna  6172  and the RF reader  6100  are similar to those in the above-mentioned sixth embodiment. The inspection/alarm part  6200  executes inspection by comparing the number of the tag information read by the RF reader  6100  with the number of the gaming currencies C detected from the line image, and generates alarms when the numbers are not equal to each other. The record part  6300  records the inspection results of the inspection/alarm part  6200  and the generated alarms. 
       FIG.  74    is a diagram indicating one groove of the gaming currency tray using a scanner as the detection means. As shown in  FIG.  74   , a slit  6178  extending in a longitudinal direction of the groove  6171  is formed at the bottom of the inner wall of the groove  6171 , and a rail  6181  is provided along the slit  6178  under the slit  6178 . An imaging element  6180  moves on the rail  6181 , so as to constitute a scanner. 
       FIG.  75    is a diagram indicating an entire configuration of the inspection system  600  in the example of  FIG.  74   . The imaging element  6180  is connected to the inspection/alarm part  6200 . The imaging element  6180  picks up an image while moving on the rail  6178 , and outputs the information of a position on the rail and the picked-up image at that position to the inspection/alarm part  6200 . The inspection/alarm part  6200  determines the existence of the gaming currencies C for the plural picked-up images obtained by picking up an image while the imaging element  6180  is moving in one direction from one end to the other end on the rail  6181 , so as to detect the number of the gaming currencies C housed in the groove  6171 . 
       FIG.  76    is a diagram indicating one groove of the gaming currency tray using a laser distance meter as detection means. As shown in  FIG.  76   , a laser distance meter  6182  is provided at an upper end of the groove  6171 . The laser of the laser distance meter  6182  is set parallel to the longitudinal direction of the groove  6171 . When the gaming currencies C stacked sequentially from the bottom are housed in the groove  6171 , the laser emitted from the laser distance meter  6182  is reflected on the surface of the uppermost gaming currency C, and returned to the laser distance meter  6182 . Accordingly, the laser distance meter  6182  measures a distance from an observation position to the gaming currency C furthest away from a reference position (the gaming currency C stacked at the uppermost part), when the upper end of the groove  6171  is an observation groove and the lower end is a reference position. 
       FIG.  77    is a diagram indicating the entire configuration of the inspection system  600  in the example of  FIG.  76   . The laser distance meter  6182  is connected to the inspection/alarm part  6200 , and outputs the measured distance to the inspection/alarm part  6200 . The larger the number of the gaming currencies C housed in the groove  6171  gets, the smaller the measured distance gets. Therefore, the inspection/alarm part  6200  detects the number of the gaming currencies C housed in the groove  6171 , based on the distance measured by the laser distance meter  6182 . 
       FIG.  78    is a diagram indicating one groove of the gaming tray using a weight meter as detection means. As shown in  FIG.  78   , the groove  6171  is located on a weight meter  6183 . When the gaming currency C is housed in the groove  6171 , the weight measured by the weight meter  6183  is increased. 
       FIG.  79    is a diagram indicating the entire configuration of the inspection system  600  in the example of  FIG.  78   . The weight meter  6183  is connected to the inspection/alarm part  6200 , and outputs the measured weight to the inspection/alarm part  6200 . The larger the number of the gaming currencies C housed in the groove  6171  gets, the heavier the measured weight gets. Therefore, the inspection/alarm part  6200  detects the number of the gaming currencies C housed in the groove  6171 , based on the weight measured by the weight meter  6183 . 
     In any of the above-mentioned examples, the detection means for detecting the number of the gaming currencies C housed in the groove  6171  by means other than RFID is provided; however, it may not be provided. The maximum number for housing the gaming currencies C in the groove  6171  is decided. So, when the RF tags are read while the maximum number of the gaming currencies C are housed in the groove  6171 , the number of the gaming currencies C physically existing at that time is already known as a maximum number. 
     Accordingly, the inspection/alarm part  6200  can detect the unfair gaming currency that does not have an RF tag or whose RF tag is broken, by comparing the number of the gaming currencies C whose tag information is read by the RF reader with the known maximum number. 
     However, the maximum number of the gaming currencies C cannot be always housed in the groove  6171  to be inspected. Then, using a spacer as a dummy currency, a vacant portion in the groove  6171  may be filled. The spacer may have the same shape (disc-like shape) as the gaming currency C, and may have the same shape (columnar shape) as the plural stacked gaming currencies C. 
       FIG.  80    is diagram indicating a status that a vacant space of the groove is filled by the spacer. The groove  6171  can house 40 gaming currencies C (the maximum housing number is 40), and 30 gaming currencies C are housed in the groove  6171 . To fill a vacant space of 10 gaming currencies, one spacer  6184  for 5 gaming currencies, one spacer  6184  for 3 gaming currencies, and two spacers  6184  for one gaming currency are housed in the groove  6171 . 
     The RF tags of the number of the currencies are built in the spacer  6184 . For example, 5 RF tags are built in the spacer  6184  for 5 currencies, 3 RF tags are built in the spacer  6184  for 3 currencies, and one RF tag is built in the spacer  6184  for one currency. 
     Accordingly, when all of 30 gaming currencies C housed in the groove  6171  are fair, the RF reader  6100  reads 40 pieces of the tag information including the RF tags built in the spacer  6184 . The inspection/alarm part  6200  determines that the unfair gaming currencies exists, and generates alarms, when the number of the tag information read by the RF reader  6100  is not equal to a predetermined value, i.e., the housable number of the gaming currencies C in the groove  6171 . 
       FIG.  81    is a diagram indicating the entire configuration of the inspection system  600  in the example of  FIG.  80   . As described above, there is no need of detection means in the example of  FIG.  80   . If inspection is executed at an arbitrary timing, a vacant space is created in the groove  6171 , so the RF reader  6100  cannot read a predetermined number of tag information, and may generate alarms. Accordingly, in the example of  FIG.  81   , a switch  6185  for instructing inspection at the inspection/alarm part  6200  is provided. The switch  6185  is pushed to generate ON signals. 
     The switch  6185  is connected to the inspection/alarm part  6200 , and outputs the ON signals to the inspection/alarm part  6200 . The inspection/alarm part  6200  instructs execution of reading to the RF reader  6100 , when receiving the ON signals from the switch  6185 . 
     The dealer collects the gaming currencies C from players losing a game, houses them in the groove  6171 , houses the spacer  6184  in the vacant spacer, and pushes the switch  6185  after there is no vacant space of the groove  6171 . Then, the RF reader  6100  reads the RF tags, and the inspection/alarm part  6200  executes inspection by determining whether the number of the read tag information is equal to a predetermined number. 
     In the sixth embodiment, a system for inspecting gaming currencies used in a casino game is explained, but an object to be inspected may be a valuable other than a gaming currency C. Also, the RF tag is embedded in the gaming currency, but a unique ID that can be individually identified by the other method may be adhered. 
     Also, in the sixth embodiment, various means for detecting the number of the gaming currencies C by means other than RFID are explained. The means for detecting the number of the gaming currencies C may be means for detecting the number of the gaming currencies including the unfair gaming currencies as the players and the dealer identify them as the gaming currencies C, for example, may be means for detecting the number of the currencies based on an image by picking up the image of the gaming currencies C housed in the gaming currency tray  617  with a camera, as in the example explained below. 
     Furthermore, the inspection system may inspect an object other than a valuable. 
       FIG.  82    is a diagram of the entire configuration of the inspection system for inspecting an object, in which the RF tag is built. The inspection system  6001  comprises a table B for locating an object. The object located on the table B is imaged with a camera  6400 , and the picked-up image is generated. The camera  6400  is connected to the inspection/alarm part  6200 , and the picked-up image is outputted to the inspection/alarm part  6200 . The inspection/alarm part  6200  comprises a neural network learnt by deep learning. The number of objects is identified from the picked-up image by the neural network, so as to detect the number of the objects. 
     Also, an RF antenna  6172  is built in the table B. The RF tag built in the object located on the table B transmits electric waves to the RF antenna  6172 , and the RF reader  6100  reads the tag information. 
     The inspection/alarm part  6200  compares the number of the tag information read by the RF reader  6100  with the number of the objects identified by the neural network, and generates alarms when both of the numbers are not equal to each other. In this manner, the number of the objects whose fairness is not known but that exist is detected by the camera  6400  that is means other than RFID. By reading the RF tags of these objects, and comparing the number of the read tag information with the number detected by the camera  6400 , the objects whose RF tag information cannot be read can be detected.
