Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
   This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2000-367280 filed on Dec. 1, 2000, the entire contents of which are incorporated herein by reference. 
   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a technique for managing a game apparatus such as an arcade game apparatus or the like using encrypted information. 
   2. Description of the Related Art 
   There has been known a penny arcade where game apparatuses are set up to have arcadians enjoy playing games and to receive payments in exchange for services rendered from the arcadians. The manager of the penny arcade sets the arcade game apparatus and manages the penny arcade. However, in many cases, the manager does not always possess the game apparatuses. The manager is permitted (licensed) to merely operate the game apparatuses under conditions predetermined between the manager and a supplier (hereinafter referred to as manufacturer) for game apparatus and game software. The manager can set up the game apparatuses in the penny arcade without cost or at very low cost instead of risking the possibility of purchasing the game apparatuses (software), and the manager pays a fixed royalty to the manufacturer from the sales. 
   Such a business model makes it possible to share the risk and profit speedily and appropriately between the developer of the game apparatus and the manager of the penny arcade as supplying new titles of games in response to the change in taste, which the fickle arcadians have. Then, this will be mainstream from now on in connection with the business model of the penny arcade. 
   In this business model, it is very important to correctly grasp the actual working state of the game apparatus periodically. Namely, the royalty is collected based on information about how many times the game is played and how many coins are put in the apparatus, and the operation of the game must be stopped when the period of a contract expires. 
   By the way, since the penny arcades are provided in amusement areas, and sightseeing spots all over the country, the technician must be on a business trip periodically to check the working state of the game apparatus, stop the apparatus whose period of contract has expired, and restart the game apparatus whose period of contract has been renewed, so that extremely much management cost is required. 
   The penny arcades in many places and the management center of the manufacturer are connected to each other over the network (Internet), a public telephone line and the like, making it possible to mange the game apparatuses at remote sites. However, there is difficulty in adopting such a method of remote control across the board since the facility environment for the penny arcades vary and there is a cost bearing problem. 
   There can be considered the method in which the management of operating the game apparatuses is left to the penny arcade and billing process is carried out based on the sales report from the penny arcade. This method, however, has a problem in which the actual state of the penny arcade and the truth of the sales report cannot be easily confirmed.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   An embodiment of the present invention will be specifically described with reference to the drawings accompanying herewith. 
     FIG. 1  is a schematic configuration view of a game apparatus managing system composed of a game apparatus and a managing apparatus,  FIG. 2  is a block diagram illustrating the configuration of the game apparatus, and  FIG. 3  is a block diagram illustrating the configuration of the managing apparatus. 
   As illustrated in  FIG. 1 , the managing system of the game apparatus of this embodiment includes a managing apparatus  40  set up at a manufacturer  1 , which is a rental source that rents game apparatuses, and a game apparatus  10  set up at a penny arcade  2 , which is a rental destination. Communication between the manufacturer and the penny arcade is performed by communication means such as a normal voice phone, FAX, mail, and the like. Regarding an application for license in connection with the rental of game apparatus, sending a license password to be described later, an inquiry about the working state, and a report on a working state information (management) password, they are carried out using the aforementioned communication means ( FIG. 1 ). 
   As illustrated in  FIG. 2 , the game apparatus  10  is composed of a main controller  11  that performs overall control of the operation of the entire game apparatus, a password analyzing processor  12  designated in modules, a software execution controller  13 , a working state managing unit  14 , a password generation processor  15 , a timer  16  that counts time in accordance with date and time information set from an outer unit, a RTC (Real Time Clock)  17  that counts time in accordance with date and time information set at the time of a factory shipment, data storage  18 , and an input/output controller  19  that receives various kinds of data inputted from apparatuses such as a game controller  21 , a coin storing device  22 , a keyboard  20 , and the like and outputs information to outputting devices such as a display device  23 , a printer  24  and the like. 
   The main controller  11  and the aforementioned processing and managing modules are implemented when a CPU, which is built in the game apparatus  10 , reads a given control program recorded on a control program recording area (not shown) appropriately and executes it. This program may be one that is recorded on a transportable recording medium such as a CD-ROM, and the like. Also, this program may be one that forms the above modules and various kinds of DBs in cooperation with an operating system, which is built in the game apparatus  10  and which is mounted on a computer main body, and/or a BIOS (Basic Input Output System). 
   The password analyzing processor  12  has a function of analyzing an encrypted game apparatus license data (license password) inputted from the keyboard to return such encrypted data to license data of a plaintext (non-encrypted data). On the other hand, the password generation processor  15  has a function of encrypting working state data of the interior of the game apparatus  10  to generate encrypted working state data (management password). The generated management password is outputted from the aforementioned display device or printer via the input/output controller  19 . 
   Regarding the encrypting and decoding technique used in the password analyzing processor  12  and the password generation processor  15 , the encryption technique, which is generally known, for example, DES (Data Encryption Standard) and the like, is used. However, they are not limited to the specific encryption technique and any encryption technique may be possible if it is a technique that makes it difficult to decode the encrypted password in a rational effort range. 
   The timer  16  is a calendar and timer capable of setting year, month, day, and time from the outer unit. Normally, the manager of the penny arcade sets the date and time at the time of setting up the apparatus, thereafter the timer  16  performs the time counting operation automatically and serves as an internal calendar and timer of the game apparatus  10 . The RTC  17  is a timer that performs the time counting operation in accordance with date and time information, which is set based on Greenwich Mean Time at a manufacturing time. The RTC  17  has a unique power source. The use of these timers will be more specifically described later. 
   The data storage  18  is a storing section for storing a game program executed by the game apparatus and various kinds of data necessary for operating the apparatus. 
     FIG. 4  is a block diagram illustrating the structure of the data storage  18 . The data storage is composed of apparatus ID storage  30  for storing an identification code (ID) of the game apparatus  10 , game program storage  31  for storing a game program executed by the game apparatus  10 , management data storage  32  for storing various kinds of data necessary for operating the game apparatus  10 , license condition storage  33  for storing a license condition at the time of renting the game apparatus  10 , and working condition storage  34  for storing a working (operating) state of the game apparatus. 
     FIG. 3  is a block diagram illustrating the configuration of a managing apparatus  40 . The managing apparatus  40  is composed of a main controller  41  that performs overall control of the operation of the entire game apparatus, a password generating processor  42  designated in modules, a password analyzing processor  43 , an input/output controller  45  that receives various kinds of data inputted from apparatuses such as a keyboard  50 , a mouse, and the like and outputs information to outputting devices such as a display device  51 , a printer  52  and the like, and a management data base (DB)  44  of the game apparatus. 
   The password generating processor  42  has a function of encrypting ID of the licensing game apparatus inputted from the keyboard and the license condition to generate license data (hereinafter referred to as license password) of the encrypted game apparatus. The password analyzing processor  43  analyzes working state data (hereinafter referred to as management password) of the game apparatus inputted from the keyboard and encrypted to return such encrypted data to management state data of a plaintext (non-encrypted data). The analyzed management password is outputted from the aforementioned display device or printer via the input/output controller  45 . 
   The encryption technique used in the password generating processor  42  must be the same as the encryption technique used in the password analyzing processor  12  of the game apparatus  10 . Also, the encryption technique used in the password analyzing processor  43  must be the same as the encryption technique used in the password generating processor  15  of the game apparatus  15 . Namely, it is required that the password analyzing processor  12  of the game apparatus  10  should correctly analyze the license password generated by the password generating processor  42  of the managing apparatus  40 . Moreover, it is required that the password analyzing processor  43  of the managing apparatus  40  should correctly analyze the management password generated by the password generating processor  15  of the game apparatus  10 . It is possible to use the encryption technique common to these password generating and analyzing processors  12 ,  15 ,  42 , and  43 . 
     FIG. 5  is a structural view of management DB  44 . The management DB  44  stores at least the apparatus ID data, information (name, address, telephone number, name of company, and the like) of the penny arcade, a current license condition, a past license condition, and data including the latest working state with respect to each of the game apparatuses to be managed. Moreover, it is possible to store a name of a model of the game apparatus to be managed at the same time (not shown). 
   The main controller  11  and the aforementioned processing (modules) are implemented when a CPU, which a computer main body built in the managing apparatus  10  has, reads a given program recorded on a program storing area (not shown) appropriately and executes it. This program may be one that is recorded on a transportable recording medium such as a CD-ROM, and the like. Also, this program may be one that forms the above modules and various kinds of DBs in cooperation with an operating system, which is mounted on the computer main body built in the managing apparatus  40 , and/or a BIOS (Basic Input Output System). 
   Sequentially, an explanation will be given of the management of the game apparatus using the game apparatus management system according to this embodiment. 
   First, an initial setting of the game apparatus  10  will be explained with reference to  FIG. 6 . 
   It is assumed that the penny arcade newly sets up the game apparatus  10  based on the license contract. When the game apparatus  10  is started (Step  101 , hereinafter simply referred to as S), the software execution controller  13  of the main controller  11  reads a start-up control program (not shown) from the management data storage  32  of the data storage  18  and requests the inputs of date sear, month, day) and current time (S 102 ). When the manager of the rental destination enters these inputs, the software execution controller  13  compares information of inputted date and time with date and time outputted from the RTC  17  (S 103 ), and determines whether or not such information is included within a given time difference range (S 104 ). The location where the game apparatus  40  is not limited to Japan, and a predetermined time difference is set to be allowable within an appropriate range as considering the case in the apparatus is set up at the foreign location. In the case where the inputted date and time are within the range of the predetermined time difference (S 104 : YES), the software execution controller  13  sets the inputted date and time to the timer  16  (S 105 ). In the case where the inputted date and time are not within the range of the predetermined time difference (S 104 : NO), the software execution controller  13  determines it as an error, and requests the re-input until the suitable date and time are inputted (S 102 ). Thus, comparison between the so-called reference date and time data supplied from the RTC  17  and date and time data to be inputted is performed, and input data, which largely deviates, is not set to the timer  16 . This makes it possible to prevent unauthorized operation of date and time data. Even if time set to the timer  16  is lost for some reasons, the current date and time is reset according to the same procedure. 
   An explanation will be next given of the license management of the game apparatus using this management system.  FIG. 7  is a sequence view illustrating the flow of the license management. The penny arcade, which wishes to rent the game apparatus, specifies a desired license period and files an application to the manufacturer. The manufacturer inputs ID of the game apparatus to be licensed, the desired license period, and other management information (including data relating to the penny arcade where the apparatus is set up) into the managing apparatus  40 . The managing apparatus  40  registers the above-inputted data to the management DB  44 , and encrypts ID of the game apparatus to be licensed and the desired license period to generate a license password using the password generating processor  42 .  FIG. 10  is an example of a screen page illustrating the data input to be displayed on the display device of the managing apparatus  40  and the display of the license password. In the case where ID of the game apparatus is AZD-D43-521-150 and the desired license period is Jun. 1, 2000 to Jun. 30, 2000, a character string of “AZDD43521150A20000601200006120000630” is encrypted using a given encryption technique, and the encrypted character string becomes a license password (e.g., A000265411). The generated license password is outputted from the display device or the printer. 
   Back to  FIG. 7 , the manufacturer transmits the generated license password to a licensee via communication means such as a telephone, FAX, mail, and the like. 
   An explanation will be next given of the input of the password and the following operation with reference to  FIG. 9 .  FIG. 9  is a flowchart illustrating the operation of the game apparatus  10 . The game apparatus  10  requests the input of the license password on the display device (S 201 ). When the licensee inputs the license password from the keyboard, the password analyzing processor  12  analyzes the inputted license password and stores the resultant to the license condition storage  33  (S 202 ). 
   Sequentially, the software execution controller  13  extracts the game apparatus ID data from the analytical result, and compares the extracted game apparatus ID with ID of the game apparatus  10  prestored in the apparatus ID storage  30  to determine whether they match each other or not (S 203 ). When they do not match each other (S 203 : NO), the software execution controller  13  displays that the license password is incorrect on the display device (S 211 ), and waits until a new password is inputted (S 201 ). When they match each other (S 203 : YES), the software execution controller  13  extracts license period data from the analytical result and determines whether or not current date data outputted from the timer  16  is between the license start time and the license end time (S 204 ). 
   In the case where the determination result is affirmative (S 204 : YES), the software execution controller  13  displays the analyzed license period on the display device, and confirms whether or not the displayed period is correct (S 205 ).  FIG. 11  is a view illustrating an example of the display of the screen page for confirmation. On the screen page, the license period corresponding to the inputted password is displayed, and the licensee can select OK or cancellation from the keyboard or the controller. In the case where the confirmation by the licensee cannot be obtained (S 205 : cancel), the software execution controller  13  does not permit the execution of the game program, and waits until a new password is inputted (S 201 ). 
   In the case where the confirmation by the licensee can be obtained (S 205 : OK), the software execution controller  13  permits the execution of the game program, and the main controller  11  starts the execution of the game program stored in the game program storage  31  (S 206 ). 
   This makes it possible for the licensee to start the business operation of the game apparatus  10  (S 207 ). After starting the business operation, the working state managing unit  14  of the game apparatus  10  records data of at least the sales (the cumulative number of coins received by the coin storing apparatus) and data of the number of playing times into the working state storage  34  of the data storage  18 . 
   In the case where the determination result is negative (S 204 : NO), the software execution controller  13  prohibits the main controller  11  from executing the game program stored in the game program storage  31  (S 208 ), and requests the input of the license password again until a suitable license password is inputted (S 201 ). Accordingly, the license cannot start the business operation of the game apparatus  10 . 
   Thereafter, the software execution controller  13  of the game apparatus  10 , which has started to execute the game program, determines whether or not current date and time data is between the license start time and the license end time (S 209 ) periodically (e.g., once a day) to check whether or not the license period is not ended. 
   In the case where the license period has not ended (S 209 : NO), the software execution controller  13  permits the main controller  11  to continue the execution of the game program. 
   In the case where the determination result is positive (S 209 : YES), the software execution controller  13  instructs the main controller  11  to stop the execution of the game program, so that the main controller stops the execution of the game program (S 210 ). After that, the software execution controller  13  requests the input of the license password again (S 201 ). In this case, the software execution controller  13  may display a message stating that the license period is ended on the screen page of the display device concurrently. 
   From the above explanation, it is understandable that the business operation of the specific game apparatus can be executed for only a given period using the encrypted license password. 
   An explanation will be next given of the management of the working state of the game apparatus  10  with reference to  FIG. 8 . 
     FIG. 8  is a sequence view illustrating the flow of the management of the working state. The licensee is obliged to periodically report the working state of the game apparatus  10  based on the license contract. In this embodiment, it is assumed that the working state data to be reported is a turnover of the game apparatus (the number of coins received by the coin storing apparatus) and/or the number of playing times. The licensee inputs a predetermined command from the keyboard, thereby instructing the game apparatus  10  to output working state information. On receipt of the instruction, the working state managing unit  14  of the game apparatus  10  extracts the game apparatus ID from the apparatus ID storage  30  and working state data to be reported from the working state storage  34 . The password generating processor  15  encrypts the game apparatus ID and working state data to be reported to generate a management password. The generated management password is outputted in a visible form from the display apparatus or the printer.  FIG. 12  is a view illustrating one example of the display of the screen page where the game apparatus  10  outputs the generated management password. The licensee transmits the generated management password to the manufacturer via communication means such as a telephone, FAX, mail, and the like. 
   The manufacturer that has received the management password inputs the management password to the managing apparatus  40 . When the management password is inputted from the keyboard, the password analyzing processor  43  of the managing apparatus  40  analyzes the inputted management password. The analyzed working state data is outputted in a visible form from the display apparatus or the printer.  FIG. 13  is a view illustrating one example of the display of the screen page where the managing apparatus  40  outputs the inputted management password and the corresponding working state data. Moreover, the analyzed working state data is recorded on the record of the corresponding game apparatus ID of the management database. 
   Back to  FIG. 8 , the manufacturer charges the licensee the royalty (license fee) according to the outputted working state based on the condition of the license contract. The licensee that has received the charge for the royalty pays the amount. At this time, in the case where the license period is already ended or comes close to end, the licensee transmits the manufacturer whether the license contract is extended. In the case where the license contract is extended (arrow A, which is connected to the same arrow of  FIG. 7 ), the operation is back to the procedure of  FIG. 7 , and a new license password is issued in accordance with the aforementioned license password issuing procedure. The manufacturer confirms the payment from the licensee. 
   From the above explanation, the manufacturer can grasp the working state of the specific game apparatus and charge the licensee the amount using the encrypted license password transmitted from the penny arcade. 
   Though the above has explained the present invention based on the specific embodiment, and it is needless to say that the present invention can adopt other embodiment without limiting to the above embodiment. 
   For example, the above embodiment has explained the case in which the manufacturer sets the license period and permits the game apparatus to be operated for only the license period. However, the other conditions may be possible. For example, the arrival at a predetermined sales after starting the operation of the game apparatus may be set as a license ending condition, and the arrival at predetermined number of times the game is played may be set as a license ending condition. In this case, instead of license period data, data indicative of a licensing method (period, the number of playing times or sales) and the content of a license (data indicative of the limit of period, the upper limit number of times the game is played or sales) may be encrypted and put in the license password generated by the managing apparatus  40 . 
     FIG. 14  is a view illustrating items that form a code sequence (numeric sequence) to be encrypted and a setting example of each item according to this alternative embodiment. In the item of the game apparatus ID, ID of the game apparatus to be licensed is inputted. In the item of the license method, any one of 1: period, 2: the number of playing times, 3: sales is inputted by use of the numeric number. In the item of license content, the content is inputted according to the specified license method. 
   For example, in the case where a license password is generated based on the conditions that the game ID is 123, the license method is 2, and the license condition is 1500 (times), x (=12321500) is calculated using the following equation:
 
 x= (game apparatus  ID ×100000)+(license method×10000)+(license content)
 
   The calculated x is substituted into the known encryption function f(x) to obtain license password y=f(x). 
     FIG. 15  is a flowchart illustrating the operation of the game apparatus  10  using such a license password according to another embodiment of the present invention. This embodiment is different from the aforementioned embodiment in only the operation after S 202  of  FIG. 9 , and only the different operation is illustrated in  FIG. 15 . First, the password analyzing processor  12  analyzes the inputted license password. Herein, the above license password y is taken as an example, and the analytical operation of the license password is explained. 
   If the license password y is substituted into a code function g(y), which is an inverse function of the above encryption function, an original code sequence x (=12321500) is uniquely obtained. From the obtained x, a license condition can be given:
 
Game apparatus  ID=x ÷100000
 
License method=( x− game apparatus  ID ×100000)÷10000
 
License content=( x− game apparatus  ID ×100000−(license method×1000))
 
   Each data of the given game apparatus ID, license method, and license content is stored in the license condition storage  33  (S 301 ). 
   The software execution controller  13  extracts the game apparatus ID data from the analytical result, and compares the extracted game apparatus ID with ID of the game apparatus  10  prestored in the apparatus ID storage  30  to determine whether they match each other or not (S 302 ). When they do not match each other (S 303 : NO), the software execution controller  13  displays that the license password is incorrect on the display device (S 304 ), and waits until a new password is inputted (S 201 ). When they match each other (S 302 : YES), the software execution controller  13  extracts data of the license method from the analytical result, and specifies the kind of data (S 303 ). In the case where the license method is 1 (period), the operations afterward are the same as those of the aforementioned embodiment, and processing is back to S 204  of  FIG. 9  (S 305 : YES). 
   In the case where the license method is the number other than 1 (namely, the number of playing times or sales) (S 305 : NO), the software execution controller  13  permits the execution of the game program, and the main controller  11  starts the execution of the game program stored in the game program storage  31  (S 306 ). In the case where the license condition is not the period, comparison and determination relating to the date and time are not performed. 
   Thereafter, the software execution controller  13  of the game apparatus  10 , which has started to execute the game program, checks data stored in the working state storage  34  periodically (e.g., after the end of one game) to determine whether or not the current number of playing times or sales is within the range of the limitation (S 307 ). 
   In the case where the determination result is affirmative (S 307  YES), the software execution controller  13  permits the main controller  11  to continue the execution of the game program. In the case where the determination result is negative (S 307 : NO), the software execution controller  13  prohibits the main controller  11  from executing the game program (S 308 ), and waits until a new password is inputted (S 201 ). 
   The above embodiment has explained the case in which the game apparatus  10  is suddenly stopped when the license period expires or the number of playing times or sales exceeds the limitation. However, the following method may be executed. 
   Namely, it is calculated how many days are left before the license period is ended or how many sales or playing times are left before they reach the limitation. Then, when the remainder of the license period becomes less than predetermined days (e.g., one month) or the remainder of the sales or playing times becomes less than a predetermined value (e.g., 100 Yen or 10 playing times), a screen page urging the manager of the penny arcade to renew the license contract may be displayed on the display device. 
   From the above explanation, it is understandable that there is disclosed the technique for managing the game apparatuses remotely without providing any special facilities to the penny arcade. According to the present invention, it is possible to start and stop an operation of the game apparatus based on a given contract condition and to transmit the working state during that time accurately to the manufacturer without using a data communication line and the like. 
   Various embodiments and changes may be made thereunto without departing from the broad spirit and scope of the invention. The above-described embodiment intended to illustrate the present invention, not to limit the scope of the present invention. The scope of the present invention is shown by the attached claims rather than the embodiment. Various modifications made within the meaning of an equivalent of the claims of the invention and within the claims are to be regarded to be in the scope of the present invention.
