Hereinafter, an overview of the whole detecting system of fraud in a game house including a plurality of game tables according to a first embodiment of the present invention will be described with referring to figures. <FIG> is a diagram illustrating an overview of the whole system, the fraud detecting system in a game house including a plurality of game tables <NUM> includes: a game recording device <NUM> that records the state of progress of a game performed in the game table <NUM> as a video including players <NUM> and a dealer <NUM> through a plurality of camera <NUM>; an image analyzing device <NUM> that performs an image analysis of the recorded video of the state of process of the game; and a card distributing device <NUM> that determines and displays a result of winning/losing of each game in the game table <NUM>. The card distributing device <NUM> 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 display lamp <NUM>.

The detecting system further includes an intelligent-type control device <NUM> that compares the rank of actual cards according to a result of the image analysis performed by the image analyzing device <NUM> and a result of winning/losing determined by the card distributing device <NUM> 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 <NUM>. The card distributing device <NUM> has a structure capable of reading ranks (A, <NUM>, <NUM> to Q, K) and suits (hearts, spades, or the like) of cards C that are manually distributed by the dealer <NUM>, and the intelligent-type control device <NUM> has a structure capable of determining match/mismatch by collating information of a rank and suites acquired by the image analyzing device <NUM> (using artificial intelligence) from a video (by using the camera device <NUM>) of cards distributed in the game table <NUM> and information of cards and suits read by the card distributing device <NUM> with each other. The image analyzing device <NUM> and the intelligent-type control device <NUM> of the 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 <NUM> and the intelligent-type control device <NUM> 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 <NUM> and are bent by the player <NUM> or contaminated. For a contaminatedcardC, as illustrated in <FIG>, 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'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 be fore 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 intelligent-type control device <NUM> having an artificial intelligence-utilizing or deep learning structure can perceive a position <NUM> (position for betting to player, banker, or pair) of chip <NUM> bet by each player <NUM>, the type (a value of a different amount is assigned to chip <NUM> for each color) of the bet chips <NUM> through the camera and the image analyzing device <NUM>. The chips are superimposed with deviations as illustrated in <FIG> from a case where the chip <NUM> is vertically arranged to be superimposed. In such a case, in a case where the camera is positioned in the direction of an arrow X illustrated in <FIG> (or the direction of the chip <NUM> is relatively in a blind area), as illustrated in <FIG>, it is assumed that the chip 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 chips due to a blind area or the like are recognized (there are case where a part of one unit of chip is hidden or a case where the whole chip <NUM> is hidden), and the number of quantity and the like can be correctly perceived. In this way, since a position <NUM> (position for betting to a player, a banker, or a pair) of chip <NUM> and the type (a value of a different amount is assigned to chip <NUM> for each color) and the quantity of the bet chip can be perceived, the intelligent-type control device <NUM> determines whether or not collection (denoted by an arrow L) of the losing chips bet by each player <NUM> and payment (9W) for winning chips to a player 6W 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 <NUM> in each game by analyzing a video of the state of process of the game through the image analyzing device <NUM>.

The intelligent-type control device <NUM> can analyze and acquire a total amount of the chips <NUM> in the chip tray <NUM> for the dealer <NUM> in the game table <NUM> by using the image analyzing device <NUM> and can compare and calculate whether or not a total amount of the chips <NUM> inside the chip tray <NUM> has been increased or decreased according to the amount of collection of the losing chips <NUM> bet by each player <NUM> and the amount of the payment 9W for winning chips to a player 6W 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 chips <NUM> in the chip tray <NUM> may be constantly acquired using means such as an RFID, and the intelligent-type control device <NUM> 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 <NUM>. For this, the artificial intelligence-type or deep-leaning structure is also used.

The intelligent-type control device <NUM> 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 chips at each player position <NUM> of the game table <NUM>, comparing a winning/losing history of each player <NUM> and the amount (won amount) of acquired chips 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 intelligent-type control device <NUM> 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 <NUM> of a specific game table <NUM>, a state in which the amount of bet chips is small at the time of losing a game, and the amount of bet chips 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 intelligent-type control device <NUM> (integrated with the image analyzing device <NUM>) of the detecting system has a structure capable of extracting an abnormal situation or specifying an individual player <NUM> at the play position <NUM> at which winning of a predetermined amount of more is acquired. In such specifying of a player <NUM>, 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 <NUM>. Then, the intelligent-type control device <NUM> has a warning function for giving a notification of the presence of a specific player in another game table when the specified player <NUM> leaves a seat and arrives at the another game table.

However, when all the chips are used, the player <NUM> can continue the game by exchanging cash (bills) with chips <NUM> on the game table (a Baccarat table or the like) without leaving the seat from the game table <NUM>. However, here, there is a chance for fraud between the dealer <NUM> and the player. The exchange of cash (bills) for chips <NUM> 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 <NUM> 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 <NUM> detects a situation other than the distribution (dealing) of cards, and the intelligent-type control device <NUM> detects exchange of bills and chips <NUM> on the game table <NUM> in a situation other than the dealing of cards (illustrated in <FIG>). 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 <NUM> or the dealer <NUM>.

The control device <NUM> 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 <NUM>, it is determined whether or not bills K to be exchanged for substitute currency <NUM> for gaming are genuine by detecting genuine marks G of the bills by emitting black light. As illustrated in <FIG>, the control device <NUM> 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 substitute currency for gaming even in a state in which a plurality of substitute currency for gaming come out onto the game table as an exchange target is hidden due to a blind area of the camera device <NUM>, comparing a total amount of the bills K come out onto the game table <NUM> from a player with a total amount of the substitute currency <NUM> for gaming come out from the dealer <NUM>, and being capable of determining whether or not both the amounts match each other.

The intelligent-type control device <NUM> has an artificial intelligence-utilizing or deep-leaning structure capable of determining whether or not a total amount of chips <NUM> placed in the chip tray <NUM> for chips for the dealer <NUM> of the game table <NUM> has been increased/decreased according to a paid amount of chips corresponding to the exchanged bills after a settlement through exchange of the bills and the chips. A case may be considered as well in which the total amount of the chips <NUM> placed in the chip tray <NUM> for substitute currency for gaming for the dealer <NUM> is constantly acquired in advance by using RFIDs of substitute currency <NUM> for gaming or the like. The intelligent-type control device <NUM> detects whether or not the increase or decrease in the known amount of the chip after the exchange of the bills and the chips and the clearing matches the exchange amount of the chips of the image analysis result. In addition, the intelligent-type control device <NUM> has an artificial intelligence-utilizing or deep-learning structure capable of determining match/mismatch of an input amount (commonly, according to key input or the like) of bills input by the dealer <NUM> and a calculated amount of bills that is a result of an image analysis performed by the image analyzing device <NUM> after the settlement through the exchange of the bills and the chips through a comparison and calculation.

Furthermore, the intelligent-type control device <NUM> has an artificial intelligence-utilizing or deep-learning structure capable of determining match/mismatch of a total addition amount of bills according to the input of a dealer in the game table <NUM> 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 <NUM> through a comparison and calculation.

As described heretofore, the control device <NUM> can recognize, through the camera <NUM> and the image analyzing apparatus <NUM>, the position <NUM> (position of player, banker, or pair wagered) on which each player <NUM> wagers the chips <NUM> and the type (different amount values are designated to different colors of the chips <NUM>) and number of the chips <NUM>, and the control device can detect who is the player <NUM> betting on the "player" (in the case where there are a plurality of the players <NUM> betting on the "player", who is the player <NUM> wagering the highest amount) and who is the player <NUM> betting on the "banker" (in the case where there are a plurality of the players <NUM> betting on the "banker", who is the player <NUM> wagering the highest amount). In this detection system, each of the image analyzing apparatus <NUM> and the control device <NUM> has a structure including a computer configured with an integrated or plural components, a program, and a memory in a complex manner.

The control device <NUM> has a structure capable of determining match or mismatch by checking information on rank and suit obtained from the image (captured by using the camera <NUM>) of each card <NUM> distributed in the gaming table <NUM> by the image analyzing apparatus <NUM> and information on rank and suit read by the card distribution device <NUM>. The control device <NUM> determines by image analysis of a progress of the game through the image analyzing apparatus <NUM> according to the win or lose result of the game determined by the card distribution device <NUM> for each game whether or not the collection of the lost chips <NUM> wagered by the players (game participants) <NUM> and the redemption of the winning chips to the winning player (game participant) <NUM> are correctly performed in accordance with the win or lose result.

As remarkable functions of the embodiment, the control device <NUM> has functions described in the following <NUM>) to <NUM>) according to the rule of the baccarat game and determines whether or not fraud in discordance with the rule is performed. Namely, the functions are as follows.

The control device <NUM> performs analysis of the information obtained by using the camera <NUM> by the image analyzing apparatus <NUM>. Namely, although the above-described surveillance of from <NUM>) to <NUM>) is performed by detecting the movement of the hands of the dealer <NUM> and the game participant <NUM>, the movement of the chips, or the movement of the hands and the movement of the chips by the using the analysis result of the image analyzing apparatus <NUM>, in a fundamental analysis, it needs to be found at least who the chips <NUM> is taken to. Hereinafter, a method of the analysis will be described with reference to <FIG>.

Analysis of Dealer <NUM> Taking Chips <NUM> Wagered by Game Participant <NUM> (<FIG>).

The chips <NUM> wagered by the game participant <NUM> losing the game are collected by the dealer <NUM>. Whether or not the collection is accurately performed is surveiled by analyzing the information obtained by using the camera <NUM> in the image analyzing apparatus <NUM>. First, a change from the state (<FIG>) that the betting chips <NUM> exist to the state (<FIG>) that the chips do not exist is detected by the image analysis. Next, an image (<FIG>) between the state that the chips <NUM> exist and the state that the chips do not exist is analyzed. In the image (<FIG>) between the state that the chips <NUM> exist and the state that the chips do not exist, which side the hand <NUM> reaches from (from the top side of <FIG> or the others) is analyzed. Fraud is detected in accordance with a rule, that is, in the case where the hand reaches from the top side (the hand movement, that is, the hand appears from the top side or the hand leaves toward the top side), the hand <NUM> is determined as the hand of the dealer <NUM>, and in the case where the hand reaches from the other directions, the hand movement is determined as fraud.

While the dealer <NUM> collects the chips <NUM> wagered by the game participant <NUM> losing the game, it is surveiled whether or not another person takes the lost chips <NUM> fraudulently (<FIG> and <FIG>). In the image between the state that the chips <NUM> exist and the state that the chips do not exist, as illustrated in <FIG>, through analyzing the movement of the loser <NUM> and the like among the game participants <NUM>, it is detected by the image analysis that the hand <NUM> reaches or moves from the bottom side of <FIG> (actually, from the top side), and the movement is determined that the hand <NUM> or the like other than the hand of the dealer <NUM> takes the chips <NUM>, so that it is determined that fraud occurs.

Analysis with Respect to Winning Chip <NUM>, Dealer <NUM> Correctly Redeeming (Placing) Chips 9W and Winner 6W among Game Participant <NUM> Taking Chips.

First, with respect to the winning chips illustrated in <FIG>, the chips 9W are redeemed in accordance with the game rule as illustrated in <FIG>. A change from the state illustrated in <FIG> to the state illustrated in <FIG> is detected, and at the same time, whether or not the hand is the hand <NUM> of the dealer <NUM> is detected by the image analysis. After that, as illustrated in <FIG>, now, whether or not the hand <NUM> of the winner 6W among the game participants <NUM> reaches (moves) the same betting area and, after that, all the chips <NUM> do not exist (state of <FIG>) is verified from the image analysis result in accordance with the game rule by the control device <NUM>, so that it is determined whether or not fraud occurs.

In addition, the control device <NUM> is configured to determine whether or not the amount of chips redeemed to the winner by the dealer <NUM> is correct according to the amount wagered by the winner 6W among the game participants <NUM>. Hereinafter, a specific example thereof is described. It is assumed that, when the chips <NUM> are overlapped in a deviated manner or are in a blind spot from the position of the camera <NUM>, the position and total amount of the chips <NUM> (which of the betting areas <NUM> of the player side and the banker side the chips <NUM> are wagered on) cannot be read normally. The control device <NUM> is configured to be capable of recognizing concealing or the like (including concealing of a portion of one chip and concealing of the entire chip) of the chip <NUM> caused by the blind spot, so that the number of chips or the like can be accurately recognized by using a self-learning function or the like according to an existing artificial intelligence utilizing type computer or control system and deep learning (structure) technique. In addition, the structure of detecting the position and type of the chip <NUM> in the betting area <NUM> is not limited thereto, but for example, the structure may be configured so that the position and the type can be detected by reading the ID buried in the chip.

As described heretofore, the control device <NUM> can recognize, through the camera <NUM> and the image analyzing apparatus <NUM>, the position <NUM> (position of player, banker, or pair wagered) on which each player <NUM> wagers the chips <NUM> and the type (different amount values are designated to different colors of the chips <NUM>) and the number of the chips, and the control device can detect who is the player <NUM> betting on the "player" (in the case where there are a plurality of the players <NUM> betting on the "player", who is the player <NUM> wagering the highest amount) and who is the player <NUM> betting on the "banker" (in the case where there are a plurality of the players <NUM> betting on the "banker", who is the player <NUM> wagering the highest amount).

In addition, the control device <NUM> of the fraud detection system in the game analyze the information obtained by the image analyzing apparatus <NUM> using the camera <NUM> by the above-described method in accordance with the rule of the baccarat game and performs surveillance. By performing the surveillance illustrated in the above-described <NUM>) to <NUM>), it is determined whether or not fraud in discordance with the rule is performed. When fraud is detected, abnormality display lamps <NUM> provided to both of the card distribution device <NUM> and the gaming table <NUM> turns on and the fraud detection outputs <NUM> to a casino management department or the like in a wireless or wired manner. A monitor or a lamp which receives the determination result to perform caution or display may be further provided to another site.

As described heretofore, the fraud is detected by the control device <NUM>, and, at the detecting time or a proper timing, a display signal is output to the display lamp <NUM> of the card distribution device <NUM> or the abnormality display lamp <NUM>. However, besides the performing of caution, after the time when the fraud or error is detected, a card distribution preventing function of the card distribution device <NUM> may be performed to prevent the distribution of the cards <NUM>.

Hereinafter, an embodiment of the card distribution device <NUM> used in a table game system according to the invention will be described with reference to <FIG>. The card distribution device <NUM> is configured to include a card containing portion <NUM> which contains a plurality of shuffle playing cards <NUM>, a card guiding portion <NUM> which guides the shuffle playing card <NUM> when the dealer <NUM> or the like manually extracts the shuffle playing card <NUM> one by one from the card containing portion <NUM> toward the gaming table <NUM>, an opening portion <NUM> for taking the card <NUM> guided from the card guiding portion <NUM>, a card detecting unit (card detecting sensors <NUM> and <NUM>) which detects that the shuffle playing card <NUM> is extracted when the shuffle playing card <NUM> is extracted, a card reading unit <NUM> which reads information representing at least the number (rank) of the shuffle playing card <NUM>, a control unit <NUM> which determines the win or lose of the card game based on the numbers (ranks) of the shuffle playing cards <NUM> sequentially read by the card reading unit <NUM>, a result display lamp <NUM> which displays the win or lose result determined by the control unit <NUM>, a distribution restricting device <NUM> which is provided to the opening portion <NUM> and restricts entering and exiting of the card <NUM> from the card containing portion <NUM>, and a management control unit <NUM> having functions equivalent to the control device <NUM>, and these components are integrated. The card distribution device has a function where, in the case where error or fraud of the dealer in the game is detected by the control device <NUM>, the further extraction of the card from the card distribution device <NUM> is stopped after the time of the detection or at a predetermined timing.

Next, the distribution restricting device <NUM> which restricts the entering and exiting of the cards <NUM> from the card containing portion <NUM> will be described with reference to <FIG> and <FIG>. The distribution restricting device <NUM> is provided to a card guide <NUM> of the card guiding portion <NUM> which guides the card <NUM> extracted one by one from the opening portion <NUM> in the front side of the card containing portion <NUM> onto the gaming table <NUM>. The distribution restricting device <NUM> has a structure where, when the card <NUM> passes through a slot <NUM> between the card guiding portion <NUM> and the guide cover of the card guide <NUM>, a lock member <NUM> presses the card <NUM> to prevent the entering and exiting of the card <NUM> in the slot <NUM>. The lock member <NUM> is moved by a driving unit <NUM> such as an electronic solenoid or a piezoelectric device as illustrated by an arrow m so as to take two states of a position (limiting position) of pressing the card <NUM> and a pass enabling position of enabling the card <NUM> to pass. The driving unit <NUM> is controlled by a control unit <NUM> which is directly or indirectly connected to the control device <NUM> in a wired or wireless manner to move the lock member <NUM> to the two states of the position of pressing the card <NUM> and the pass enabling position of enabling the card <NUM> to pass. The rule of the baccarat game is programed and stored in advance in the control unit <NUM>.

Next, a modified example of the distribution restricting device <NUM> will be described with reference to <FIG>. In the modified example, the distribution restricting device <NUM> has a structure where, when the card <NUM> passes through the slot <NUM> between the card guiding portion <NUM> and the card guide <NUM> (guide cover), the lock member <NUM> projects into the slot <NUM> to prevent the movement of the card <NUM>. The lock member <NUM> is moved by a driving unit <NUM> such as an electronic solenoid or a piezoelectric device as illustrated by an arrow m so as to take two states of a position (limiting position) of preventing the movement of the card <NUM> and a pass enabling position of enabling the card <NUM> to pass. The driving unit <NUM> is controlled by the control unit <NUM> which is connected to the control device <NUM> to move the lock member <NUM> to the two states of the position of preventing the movement of the card <NUM> and the pass enabling position of enabling the card <NUM> to pass.

Next, details of the code reading unit <NUM> which reads a code <NUM> representing a digit (number, rank) of the card <NUM> from the card <NUM> when the card <NUM> is manually extracted from the card containing portion <NUM> will be described. <FIG> is a plan diagram illustrating main components of the card distribution device <NUM>. In the figure, the code reading unit <NUM> is provided to the card guiding portion <NUM> which guides the card <NUM> manually extracted one by one from the opening portion <NUM> in the front side of the card containing portion <NUM> onto the gaming table <NUM>. The card guiding portion <NUM> is formed to have a slanted surface, and the card guides <NUM> functioning as a sensor cover are provided to two edges of the card guiding portion. In addition, each of the two card guides <NUM> is formed detachable by using a screw or the like (not shown). If the card guides <NUM> are detached, sensor groups <NUM> of the code reading unit <NUM> are exposed. The sensor group <NUM> is configured with four sensors including two UV-ray sensitive sensors (UV sensors) <NUM> and <NUM> and object detection sensors <NUM> and <NUM>.

The object detection sensors <NUM> and <NUM> are optical-fiber type sensors of detecting the existence of the card <NUM> and can detect the movement of the card <NUM>. One object detection sensor <NUM> is located at the upstream side of the card guiding portion <NUM> in the card <NUM> flowing direction, and the other object detection sensor <NUM> is located at the downstream side. As illustrated in the figure, the two object detection sensors <NUM> and <NUM> are provided at the respective upstream and downstream sides to interpose the UV sensors <NUM> and <NUM>. The UV sensors <NUM> and <NUM> have LEDs (UV LEDs) emitting a UV ray and sensors. A mark M of the code <NUM> is printed on the card <NUM> by using UV ray emitting ink which exhibits color if the ink is hit by the UV ray. By irradiating the card <NUM> with the UV ray (black light), reflected light of the mark M of the code <NUM> of the card <NUM> is sensed by the sensor. The UV sensors <NUM> and <NUM> are connected to the code reading unit <NUM> and the control unit <NUM> through cables. In the code reading unit <NUM>, a combination of the marks M is determined and the number (rank) corresponding to each code <NUM> is determined from the output signal of the sensors, that is, the UV sensors <NUM> and <NUM>.

In the code reading unit <NUM>, starting and ending of the UV sensors <NUM> and <NUM> are controlled by the control unit <NUM> based on the detection signals of the object detection sensors <NUM> and <NUM>. In addition, the control unit <NUM> determines based on the detection signals of the object detection sensors <NUM> and <NUM> whether or not the card <NUM> passes through the card guiding portion <NUM> normally. As illustrated in <FIG>, two rows and four columns of the rectangular marks M representing the rank (number) and suit (heart, spade, or the like) of the card are arranged in the edge of the card <NUM>. If the UV sensors <NUM> and <NUM> sense the mark M, the sensors output "on" signals. The code reading unit <NUM> determines a relative relationship between the two signals input from the two UV sensors <NUM> and <NUM>. Therefore, the code reading unit <NUM> specifies the code according to a relative difference between the two marks M sensed by the two UV sensors <NUM> and <NUM> to specify the number (rank) and type (suit) of the corresponding card <NUM>.

The relationship between the code <NUM> and the outputs of the "on" signals of the two UV sensors <NUM> and <NUM> is illustrated in <FIG>. Based on the result of comparison of the relative change of the outputs of the "on" signals of the UV sensors <NUM> and21, a predetermined combination of the marks M can be specified. As a result, four combinations of the marks M of the up and down two columns are obtained, and if the four combinations are printed in four columns, <NUM> to the 4th power, that is, <NUM> types of codes can be configured. By assigning <NUM> types of cards of the trump cards to <NUM> types of the codes, details of the assignment is stored as a comparison table in a memory or as a program, and the code reading unit <NUM> is configured so that, by specifying each code <NUM>, the number (rank) and type (suit) of the card <NUM> is specified from a pre-defined comparison table (not shown). In addition, since the <NUM> types of the codes are stored in the comparison table in a manner that the codes are freely combined to be in association with the <NUM> types of the cards, the combinations may be complicated, and thus, the combinations of the <NUM> types of the codes and the <NUM> types of the card can be changed according to time and location. It is preferable that the code is printed by using a paint which is visualized by being irradiated with UV light and the code is printed at a position where the codes do not overlap a type indicator or index <NUM> of the card.

Heretofore, although various embodiments of the invention are described, the above-described embodiments can be modified within the scope of the invention by the skilled in the art, and if needed in a game to which the embodiment is applied, the apparatus according to the embodiment may be appropriately modified.

A management system according to a third 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's mistakes in handling substitute currency for gaming (chip). A game house includes monitoring cameras used for monitoring dealer's mistakes in handling chips, and such mistakes are prevented using a determination of mistakes and fraud according to collection and repayment of substitute currency for gaming 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 substitute currency for gaming, it has been proposed to acquire the amount of the substitute currency for gaming by attaching an IC tag to each substitute currency for gaming.

In a card game monitoring system disclosed in PCT Application Publication No. <CIT>, it is determined whether or not substitute currency for gaming 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 substitute currency for gaming, and monitoring of dealer's mistakes in handling the chips is performed.

In game houses such as casinos, while substitute currency for gaming 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, substitute 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 substitute currency for gaming at each position cannot be perceived. In addition, conventionally, as illustrated in <FIG>, the pattern of substitute currency for gaming (chip) T is complicated, and, when a plurality of chips 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 substitute currency for gaming 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 chip, since the pattern of the substitute currency for gaming (chip) is complicated, there is a problem in that it cannot be determined whether or not a dealer correctly performs re-payment when chip corresponding to the bet chip 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 substitute currency for gaming 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 substitute currency for gaming 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 substitute currency for gaming 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 substitute currency for gaming 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 substitute currency for gaming 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 substitute currency for gaming by measuring the number of coloring layers, the white layers, or the thin-color layers of the substitute currency for gaming placed by each game participant.

In order to solve the various problems, substitute currency for gaming 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 substitute currency for gaming can be specified by using the coloring layer.

In addition, in the substitute currency for gaming, on the surface of the white layer or the thin-color layer, a print representing the type of the substitute currency for gaming 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 substitute currency for gaming, marks using UV ink or carbon black ink 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 substitute currency for gaming according to this embodiment includes: a passage including an inlet and an output through which the substitute currency for gaming can pass in a radial direction; a chip 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 substitute currency for gaming passing through the passage; a mark reading device that reads a mark, which is formed using the UV ink or the carbon black ink, arranged on the surface of the passing substitute currency for gaming; a print inspecting device that reads a print representing the type arranged on the surface of the substitute currency for gaming 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 substitute currency for gaming determined by the chip 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 substitute currencies for gaming (chip) are piled up, the quantity of the chips can be determined, and a total amount of relatively overlapping substitute currency for gaming 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> 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 <NUM> includes: a measurement device <NUM> including an image analyzing device <NUM> that records a state of process of a game played in the game table <NUM> as a video including game participants <NUM> and a dealer <NUM> through a plurality of cameras <NUM> and performs an image analysis of the recorded video of the state of process of the game; and a card distributing device <NUM> that determines and displays a result of winning/losing of each game in the game table <NUM>. The card distributing device <NUM> 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 <NUM>.

The management control device <NUM> reads information (ranks and suits) of cards C acquired from the card distributing device <NUM> and determines a result of winning/losing of each game and determines a winner 6W and a loser <NUM> among the participants <NUM> in each game by using a result of measurement of the position, the types, and the quantities of substitute currency <NUM> (chips <NUM>) for gaming placed by the game participants <NUM>. In addition, the management control device <NUM> has a calculation function of calculating a balance (an amount acquired by subtracting a total amount of substitute currency <NUM> (chips <NUM>) for gaming that is re-paid to a winner 6W among the participants <NUM> from a total amount of substitute currency <NUM> (chips <NUM>) for gaming bet by the loser <NUM>) of the casino side in the game table <NUM> for each game.

The image analyzing device <NUM>, the measurement device <NUM>, and the management control device <NUM> 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 substitute currency for gaming (chip) used in this detection system will be described. <FIG> is a front cross-sectional view of substitute currency <NUM> (chip <NUM>) for gaming used in this detection system. The substitute currency <NUM> for gaming has a multi-layer structure in which a plurality of plastic layers having different colors are stacked, a coloring layer <NUM> is included at least in the middle, and white layers <NUM> 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 <NUM>) are stacked on both sides of the coloring layer <NUM> of the middle. In this way, by employing a multi-layer structure in which the coloring layer <NUM> is included, and white layers <NUM> 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 <NUM>) are stacked on both sides of the coloring layer <NUM> of this middle, as illustrated in <FIG>, a stripe pattern is formed on the side face in the stacking direction, and the type of the substitute currency <NUM> for gaming (<NUM> points, <NUM> points, <NUM> points, <NUM> points, and the like) can be specified by changing the color (red, green, yellow, blue, or the like) of the coloring layer <NUM>.

In addition, as illustrated in <FIG>, in the substitute currency <NUM> for gaming, prints <NUM>(<NUM> points or the like) representing the type of the substitute currency <NUM> for gaming are formed on the surfaces (the upper face and the lower face) of the white layer <NUM>. As illustrated in <FIG>, the transparent layers <NUM> are disposed in the outermost layers, and each interlayer is thermos-compressed, and a structure of at least five layers is formed. Such substitute currency <NUM> for gaming is formed by using a plastic material having a thin long shape, and layers (the coloring layer <NUM>, the white layer <NUM>, and the transparent layer <NUM>) 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 <NUM> of the outermost layer.

In addition, in the substitute currency <NUM> for gaming, mark M using the UV ink or carbon black ink are arranged on the surface of the white layer <NUM> (see <FIG>). This mark M represent the authenticity of the substitute currency <NUM> for gaming, 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. In the outermost layers, while transparent layers <NUM> are thermally compressed or formed as coating layers to cover the print <NUM> and the mark M, embossing processing is performed for these transparent layers <NUM>, and the close adherence between the substitute currencies <NUM> for gaming is prevented.

The R processing (R) is performed for the ends of the transparent layers <NUM> of the outermost layer for which the print <NUM> (<NUM> points or the like), and in the punching process of the substitute currency <NUM> for gaming, the surfaces of the white layers <NUM> are prevented from being deformed to appear on the side face. In addition, it is prevented that a sharp end remains in the substitute currency <NUM> for gaming and damages the hands or the other chips.

The coloring layer <NUM>, as illustrated in <FIG>, may be formed by a plurality of colored layers (three layers in the case illustrated in <FIG>). Since the plurality of colored layers (three layers in the case illustrated in <FIG>) are thermos-compressed, a state in which the three-layer structure can be visually observed, as illustrated in <FIG>, is not formed. However, three layers are illustrated in <FIG> for description. In addition, in a middle layer among the three layers of the coloring layer <NUM>, a partly hollowed portion B is arranged, and an RFID <NUM> is built therein.

<FIG> is a perspective explanatory photographic diagram that illustrates a state in which substitute currency for gaming of different types are piled up. The management control device <NUM> images substitute currency <NUM> for gaming placed on the game table <NUM> by the game participant <NUM> by using the camera <NUM> and measures each area <NUM> (whether the bet is on the banker, the player, the pair, or the tie) in which the substitute currency <NUM> for gaming (chip <NUM>) is placed by using the measurement device <NUM> including the image analyzing device <NUM>, and the measurement device <NUM> (by using information acquired by the image analyzing device <NUM>) analyzes and measures the number and the colors of coloring layers <NUM> (or the thin-color layers) or white layers <NUM> of the substitute currency <NUM> for gaming that is stacked in each area and determines the types and the quantities of the substitute currency <NUM> for gaming.

The management control device <NUM> may be a control device having an artificial intelligence-utilizing or deep learning structure. The management control device <NUM> can perceive the position <NUM> (a position betting on a player, a banker, or a pair), the types (a value of a different amount is assigned to the substitute currency <NUM> for gaming for each color), and the quantities of the substitute currency <NUM> for gaming that is bet by each participant <NUM> through the camera <NUM> and the image analyzing device <NUM>. The artificial intelligence-utilizing computer or control system can perceive the position <NUM> (aposition betting on a player, a banker, or a pair), the types (a value of a different amount is assigned to the substitute currency for gaming for each color), and the quantities of the substitute currency <NUM> for gaming 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 <NUM> in each game, determines whether or not the collection (denoted using an arrow L) of substitute currency <NUM> for gaming bet by a losing participant <NUM> and the re-payment (payment (9W)) for winning substitute currency <NUM> for gaming for the winning game participant 6W 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 <NUM> through the image analyzing device <NUM>.

In such a case, as illustrated in <FIG> (compared to conventional chip illustrated in <FIG>), a stackedmulti-layer structure is formed, and a stripe pattern is formed on the side face in the stacking direction, and accordingly, the measurement device <NUM> including the image analyzing device <NUM> can accurately perform the measurement of the types and the quantities of schips 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 <NUM> can analyze and perceive a total amount of substitute currency <NUM> for gaming in the tray <NUM> for substitute currency for gaming for the dealer <NUM> of the game table <NUM> by using the image analyzing device <NUM> and can determine through a comparison and calculation whether or not a total amount of the substitute currency <NUM> for gaming placed inside the tray <NUM> for substitute currency for gaming has been increased/decreased according to the collection of the losing substitute currency <NUM> for gaming bet by each game participant <NUM> and the amount of the payment 9W for winning substitute currency for gaming to the winning game participant 6W after the game ends and is settled based on the result of winning/losing of the game.

The management control device <NUM> of this system, the ID reading device <NUM> disposed inside, and the chip determining device <NUM> specifying the types and the quantities of substitute currency <NUM> for gaming 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 substitute currency <NUM> for gaming (so-called substitute currency for gaming) used in this system will be described. <FIG> is a front view of substitute currency <NUM> for gaming (chip) used in this system, the substitute currency <NUM> for gaming is formed by stacking a plurality of 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 substitute currency <NUM> for gaming manufactured in this way has a multi-layer structure in which a coloring layer <NUM> is included at least in the middle, and white layers <NUM> or thin-color layers (may be layers of a color thinner than that of the coloring layer <NUM>; not illustrated in the drawing) are stacked on both sides (in <FIG>, the upper and lower sides) of the coloring layer <NUM> disposed in the middle. In this way, by employing the multi-layer structure in which the coloring layer <NUM> is included, and the white layers <NUM> or the thin-color layers (may be layers of a color thinner than that of the coloring layer <NUM>; not illustrated in the drawing) are stacked on both sides of the coloring layer <NUM> disposed in the middle, as illustrated in <FIG>, 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 <NUM> of the substitute currency <NUM> for gaming, the type of the substitute currency <NUM> for gaming (<NUM> points, <NUM> points, <NUM> points, <NUM> points, and the like) can be specified.

In addition, as illustrated in <FIG>, in the substitute currency <NUM> for gaming, a ID <NUM> representing the type of substitute currency <NUM> for gaming is applied to the side faces of the white layers <NUM>.

In the outermost layers, transparent layers <NUM> are arranged, and each interlayer is thermo-compressed to form a structure of at least five layers. Such substitute currency <NUM> for gaming is formed by using a plastic material having a thin long shape, and layers (at least the coloring layer <NUM> and the white layers <NUM>) are thermo-compressed to form a closely adhering state (the structure of five layers or the like) in the state of along 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 <NUM> of the outermost layer. The transparent layers <NUM> may be a coat layer of varnish. The unique ID <NUM> is attached to at least three positions on the side face of the substitute currency <NUM> for gaming. The unique ID <NUM> is attached through inkjet printing using ink that is visible for visible light.

Particularly, in this embodiment, the unique ID <NUM> 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>, 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>. A configuration in which upper and lower marks C are paired to configure a code (four types) is illustrated in <FIG>. 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>, 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 <NUM> codes can be configured. Since there are four types of a <NUM>-digit code, <NUM> to the power of <NUM> codes are acquired, and accordingly, the unique IDs <NUM> of substitute currency <NUM> for gaming can be sufficiently assigned.

The substitute currency <NUM> for gaming 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 <NUM> is included at least in one layer, the white layers <NUM> or the thin-color layers are stacked on a further outer side than the coloring layer <NUM> and has a configuration enabling the type of the substitute currency <NUM> for gaming to be specified using the coloring layer <NUM>. The side IDs <NUM> are disposed at least three positions (preferably, six positions) on the side face of the white layer <NUM> or the thin-color layer, and, in this example, six IDs are disposed at a predetermined interval of <NUM> degrees in the rotation direction. The unique IDs <NUM> individually identifiable (different for each one) are attached to substitute currency <NUM> for gaming, and the unique IDs <NUM> are disposed at a predetermined interval of <NUM> degrees in the rotation direction (circumferential direction) such that the side ID is necessarily seen from the lateral side. The unique IDs <NUM> attached to the substitute currency <NUM> for gaming are read by the ID reading device <NUM> described above. The type, the manufacturing information, and the like of substitute currency <NUM> for gaming can be specified by reading the side ID <NUM> by using the ID reading device <NUM>, and a configuration in which the ID <NUM> can be managed in the database <NUM> is formed. In this embodiment, the unique IDs are attached using ink that is visible for visible light through inkjet printing. The unique IDs <NUM> may be attached by inkjet printing using invisible ink (UV ink, carbon black ink, or infrared reactive ink) that is invisible for visible light.

The unique IDs <NUM> attached to the substitute currency <NUM> for gaming are read by the ID reading device <NUM> described above, and the ID reading device <NUM> can read the substitute currency <NUM> for gaming held in the storage <NUM> of a cashier of a game house and the game table chip tray <NUM> of the game table, and actually, as illustrated in <FIG>, when the substitute currency <NUM> for gaming is stacked horizontally, the IDs <NUM> can be read.

Furthermore, in the substitute currency <NUM> for gaming, a mark M using UV ink or carbon black ink is arranged on the surface (X) of the white layer <NUM>. This mark M represents authenticity of substitute currency <NUM> for gaming, and, when ultraviolet rays (or infrared rays) hit the mark M, the mark M becomes visible to the eyes and represents authenticity based on a combination of the forms and a number. While the transparent layers <NUM> are thermos-compressed or coated in the outermost layers to cover a print <NUM> (<NUM> points or the like) used for specifying a game house and a mark M disposed on the surface, embossing process or varnish processing is performed for the transparent layers <NUM>, and the substitute currency <NUM> for gaming is prevented from adhering to each other and is caused to slide well.

The R processing (R) is performed for the ends of the transparent layers <NUM> of the outermost layers for which a print <NUM> (<NUM> points or the like) is performed, and, in the punching process of the substitute currency <NUM> for gaming, the surfaces of the white layers <NUM> are prevented from being deformed to appear on the side face. In addition, it is prevented that a sharp end remains in the substitute currency <NUM> for gaming and damages the hands or the other chips <NUM>. The coloring layer <NUM> 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 <NUM>. In addition, a part of the coloring layer <NUM> is hollowed out, or a space is arranged between the coloring layer <NUM> and the white layer <NUM>, and an RFID may be built therein. In such a case, as the ID <NUM> of the substitute currency <NUM> for gaming, a ID <NUM> according to a code using the marks C and a ID using the RFID are used together.

In the substitute currency <NUM> for gaming configured in this way, the types and the quantities of the substitute currency <NUM> for gaming that is held in the game table chip tray <NUM> and the storage <NUM> are specified by the chip determining device <NUM> through the camera <NUM> and the ID reading device <NUM>, and the IDs <NUM> of the substitute currency <NUM> for gaming present on the game table chip tray <NUM> and the storage <NUM> are managed in the database <NUM> together with the presence information thereof. In this way, at least, it is inspected whether <NUM>) a ID <NUM> that has not been present in the database <NUM> is newly present <NUM>) two or more same IDs <NUM> are present. By determining the occurrences of the situations of <NUM>) and <NUM>) described above by searching for all the IDs <NUM>, the inspection is realized.

The management control device <NUM> may be a control device having an artificial intelligence-utilizing or deep learning structure. The management control device <NUM> can perceive the position <NUM> (a position betting on a player, a banker, or a pair), the types (a value of a different amount is assigned to the substitute currency for gaming for each color), and the quantities of the substitute currency <NUM> for gaming by using an artificial intelligence-utilizing type computer or control system, a deep-learning (structure) technology, a self-learning function, or the like.
