[0077] In the game coin manufacturing factory 200, in parallel with the manufacture of the game coin 72, a data file 73 recording a combination of a tag ID and a game coin ID (hereinafter, the tag ID and the game coin ID are collectively referred to as "identification information") is prepared. While providing the manufactured game coins 72 to the casino 300, the game coin manufacturing factory 200 provides the data file 73 to the casino 300 through a different path. It should be noted that the data file 73 can be sent to the casino 300 by the manufacturer of the game coin 72 via email, or can be recorded in a mobile storage medium by the manufacturer of the game coin 72 and handed over to the casino 300, or can be saved in a cloud storage by the manufacturer of the game coin 72 and then downloaded by the casino 300. At this time, the data file 73 is provided to the casino 300 by the game coin manufacturing factory 200 in an encrypted state by an appropriate method.

[0078] The casino 300 has a backstage 301, which is a secure area that the players 74 cannot enter, and a game pool 302 for the players 74 to play games. The backstage 301 includes a warehouse 31 for storing game supplies including game coins 72, a procedure room 32 in which the procedure for activating the game coins 72 is performed, and a cashier room 33 and a bank room 34 that are connected to the game pool 302.

[0079] The cashier's room 33 has a window communicating with the game pool 302. In the cashier's room 33, game coins 72 are given to players 74 of the game pool 302 for exchange with cash, and cash is given to players 74 for exchange with game coins 72 given by players 74 of the game pool 302. That is, players 74 can purchase game coins 72 with cash through the window of the cashier's room 33, and can exchange game coins 72 for cash.

[0080] The bank room 34 and the game table 35 are used to supply and deposit game coins 72. Supply means that when the game coins 72 supplied from the game table 35 to the game table 36 are insufficient, the game coins 72 are supplied from the bank room 34 to the game table 35. Deposit means that when the game coins 72 on the game table 35 are sufficient, the game coins 72 are returned from the game table 35 to the bank room 34. For this purpose, a passage or window for depositing and withdrawing game coins 72 between the bank room 34 and the game pool 302 is prepared.

[0081] The game coins 72 supplied from the game coin manufacturing factory 200 to the casino 300 are first stored in the warehouse 31 of the backstage 301. In the procedure room 32, the game coins 72 stored in the warehouse 31 are activated. The game coins 72 that have undergone the activation procedure are brought into the game pool 302 via the cashier's room 33 or the bank room 34. It should be noted that once the game coins 72 that have undergone the activation procedure are stored in the warehouse 31, they can be provided from the warehouse 31 to the cashier's room 33 or the bank room 34.

[0082] The player 74 can purchase game coins 72 in the cashier room 33 or the game table 36. The player 74 places game coins 72 in the game played at the game table 36. If the player wins the game, the game coins 72 are returned to the dealer 75. If the player loses the game, the game coins 72 placed are recovered by the dealer 75. In this way, the game coins 72 held by the dealer 75 of the game table 36 increase or decrease due to the game. If the game coins 72 on the game table 36 are insufficient, the game coins 72 are replenished from the game table 35 to the game table 36. If the game coins 72 on the game table 36 are excessive, the game coins 72 are moved from the game table 36 to the game table 35. In addition, the player 74 can enter and exit the game pool 302 through the entrance 38. Depending on the casino, it is allowed to carry the game coins 72 directly into and out of the game pool 302. The game table 35 manages a plurality of game tables 36.

It should be noted that the entrance 38 can also be provided with an entrance system that is the same as the above-mentioned subsystems.

[0092] (activation)

[0093] The following is an explanation of the activation procedure performed in the procedure room 32. The game coins 72 manufactured in the game coin manufacturing factory 200 are brought to the backstage 301 of the casino 300 and stored in the warehouse 31. In the procedure room 32, the game coins 72 stored in the warehouse 31 are taken out, and the activation procedure of the game coins 72 is performed using the procedure room system 320.

[0094] The processing room system 320 has a data file 73 containing identification information provided by the game coin manufacturing factory 200 (the manufacturer of the game coin 72), and the processing room system 320 receives the data file 73 using an input device 324. Since the data file 73 is encrypted, the input device 324 decrypts the data file 73. It should be noted that in addition to the identification information, the data file 73 may also record a part or all of the other information stored in the RFID tag 721 of each game coin 72 (see Figure 3 ).

[0095] The antenna 321 and the activation reader / writer 322 read the tag ID and the game coin ID as identification information from the RFID tag 721 of the game coin 72 to be activated. The registration device 325 determines (compares) whether the identification information read from the game coin 72 by the activation reader / writer 322 exists in the identification information stored in the data file 73 decrypted by the input device 324, thereby determining whether the game coin 72 is a genuine game coin officially manufactured by the game coin manufacturing factory 200, or a fake game coin that is not officially manufactured by the game coin manufacturing factory 200, or a game coin with a faulty RFID tag 721. That is, the registration device 325 determines the authenticity of the game coin 72 based on whether the identification information stored in the RFID tag 721 of the game coin 72 is consistent with the identification information stored in the data file 73 (first verification).

[0096] When the registration device 325 determines that the game coin 72 is a genuine game coin in the authenticity determination, it records its identification information (tag ID and game coin ID) in the database 326, thereby registering the game coin 72. At this time, when other information such as manufacturing information is recorded in the RFID tag 721 and / or the data file 73 of the game coin 72, this information is also recorded in the database 326 in association with the identification information. Further, the registration device 325 records the activation information of each game coin 72 in the database 326.

[0097] Figure 5 2 is a diagram showing the data structure of the information of each game coin recorded in the database of the embodiment of the present invention. In this embodiment, for each game coin 72, the database 326 records the following information: record the tag ID as tag identification information 261, record the attribute and value as type information 262, record the manufacturing factory ID and manufacturing date as manufacturing information 263, record the game coin ID and game coin symbol ID as game coin identification information 264, record the usability status and update time and date as activation information 265, and record the location and read time and date combination history record as location history record information 266.

[0098] When the game coin 72 of the game coin that is successfully checked and judged to be true is registered in the database 326, the registration device 325 records the usability status of its activation information 265 as "valid", and records the time and date at that time as the update time and date, thereby activating (validating) the game coin 72 as a usable game coin. Thus, by referring to the database 326, it is possible to determine whether the usability status of each game coin 72 is "valid" or "invalid", and it is also possible to know when activation (when registration) was performed.

[0099] In this embodiment, the EPC area 212 of the RFID 721 of the game coin 72 also records the activation information, so the registration device 325 controls the writing function of the activation reader 322 as the registration process of the usable game coin 72, so that the usability status recorded in the RFID tag 721 of the game coin 72 that is successfully checked and judged to be a real game coin can be rewritten from "invalid" to "valid" via the antenna 321. Thus, the systems 330 to 360 at each game supplies processing location can know whether the usability status of the game coin 72 is "valid" or "invalid" only by reading the RFID tag 721 of the game coin 72.

[0100] As mentioned above, the game coin 72 is invalid before being transported to the entertainment venue 300 from the game coin manufacturing plant 200 until it is validated by the procedure room system 320. Therefore, in the process of transfer, even if there is a situation that the game coin 72 is stolen, the stolen game coin 72 cannot be used in the game pool 302 of the entertainment venue 300. The entertainment venue only needs to strictly manage the game coin 72 after being validated by the activation procedure, which can improve the safety level compared to the situation that strict management must be carried out from the stage of manufacturing the game coin 72, and reduce the safety cost. In addition, after registering the game coin 72 in the background, until actual use, whether the use status is registered as "invalid", so that even if the game coin 72 kept in the background is stolen, such game coin 72 cannot be used, and safety can be ensured.

[0101] (Comparison of game supplies processing position)

[0102] In the cashier room 33, the bank room 34, the game table 35, and the game table 36, which are the game supplies processing locations, the identification information of the game coins 72 to be processed therein is compared and the usability status is confirmed by using the cashier system 330, the bank system 340, the game table system 350, and the game table system 360, respectively. The following is a description of each game supplies processing location.

[0103] In the cashier's office 33, the antenna 331 and the cashier reader / writer 332 of the cashier system 330 read the RFID tag 721 of the game coin 72 in the cashier's office 33, and obtain the tag ID, the game coin ID, and the usability status. First, when the usability status read from the RFID tag 721 of the game coin 72 is "invalid", the cashier comparison device 333 outputs an error signal indicating this situation. When the error signal is output, the cashier's office 33 stops processing the game coin 72.

[0104] The cashier control device 333 also sends the identification information (tag ID and game coin ID) obtained by the cashier reader / writer 332 to the procedure room system 320. The central control device 323 of the procedure room 330 checks whether the identification information received from the cashier system 330 is stored in the database 326, and confirms whether the usability status associated with the identification information is valid.

[0105] When the corresponding identification information is stored in the database 326 (i.e., it is a genuine game coin) and the usability status is valid, the central control device 323 sends a response signal indicating that the game coin 72 is a genuine game coin and is valid to the cashier system 330. On the other hand, when the game coin 72 under control is not a genuine game coin, the central control device 323 sends an error signal indicating that it is not a genuine game coin as a response signal to the cashier system 330. Even if the game coin 72 under control is a genuine game coin but the usability status is invalid, the error signal indicating that it is a genuine game coin but invalid is sent to the cashier system 330 as a response signal.

[0106] It should be noted that, if the usability status read from the RFID tag 721 of the game coin 72 by the cashier comparison device 333 is valid, but there is a game coin 72 whose usability status is recorded as invalid in the database 326, the cashier comparison device 333 determines that the game coin 72 is a counterfeit game coin, and controls the writing function of the cashier reader / writer 332 to rewrite the usability status of the RFID tag 721 of the game coin 72 to "invalid" via the antenna 331. Alternatively, the cashier comparison device 33 can rewrite the usability status to "unknown".

[0107] In addition, in the database 326, the usability status is recorded as "valid", but in the case where the usability status read from the RFID tag 721 of the game coin 72 in the cashier comparison device 333 is "invalid", it is determined that the usability status of such game coin 72 stored in the RFID tag 721 of the game coin 72 is rewritten for some reason, and the usability status stored in the RFID tag 721 of the game coin 72 can be rewritten to "valid". Alternatively, the usability status of such game coin 72 can be rewritten to "invalid" or "unclear", and the processing thereof is terminated.

[0108] For the game coins 72 brought into the cashier's room 33 directly from the procedure room 32 or via the warehouse 31, since they have been activated in the procedure room 32, the possibility of counterfeit or improper game coins is low, but for the game coins 72 brought in and exchanged by the user from the game pool 302, there may be counterfeit or improper game coins 72. Therefore, in particular, for the game coins 72 involved in the exchange, the cashier's comparison device 333 can compare the identification information and confirm whether the status can be used, and show the results to the player 74 and the cashier's staff. Alternatively, when the player 74 purchases the game coin 72, the value information stored in the RFID tag 721 of the game coin 72 can be read and the information is shown to the player 74, and the identification information is also compared and the status can be confirmed, and the results are shown to the player 74 together with the value information.

[0109] The bank system 340 also basically performs the same operation as the cashier system 330. The replenished game coins 72 are carried from the bank room 34 to the game table 35 of the game pool 302. Such game coins 72 are activated in the procedure room 32, so it is difficult to consider that they are counterfeit or mixed with improper game coins 72. However, for the game coins 72 brought from the game pool 302 to the bank room 34 when depositing, including game coins temporarily handed over to the players 74 and then recovered by the dealer, there is a possibility that counterfeit or improper game coins 72 are mixed. Therefore, in particular, for the game coins 72 brought from the game pool 302, the bank system 340 can refer to the database 326 to compare the identification information and confirm whether the game coins can be used.

[0110] The game table system 350 also performs basically the same operation as the cashier system 330. The game coins 72 supplied from the bank room 34 and the game coins 72 surplus on the game table 36 are brought into the game table 35. The game table system 350 compares the game coins 72 brought into the game table 35 in this way. In addition, the game coins 72 surplus on the game table 35 are moved to the bank room 34 (deposited), or when the game coins 72 on the game table 36 are insufficient, the game coins 72 are replenished from the game table 35 to the game table 36. The game table system 350 also compares the game coins 72 transported out of the game table 35 in this way.

[0111] The operation of the game table system 360 is as follows. In the game table 36, the dealer 75 returns the game coin 72 from the game coin tray 36a to the player 74 who wins the game. The antenna 361a is mounted on the game coin tray, and the game coin tray reader / writer 362a reads the identification information and the usability status from the RFID tag 721 of the game coin 72 stored in the game coin tray. The identification information read by the game coin tray reader / writer 362a is compared by the game table comparison device 363 and stored in the game table storage device 364. In the case where a plurality of game coins 72 are stored in the game coin tray, the game table storage device 364 stores a plurality of identification information corresponding to the plurality of game coins 72.

[0112] The game table comparison device 363 first compares the latest past identification information stored in the game table storage device 364 with the current identification information read by the game coin tray reader / writer 362a, and determines whether the two are consistent.

[0113] When there is identification information in the identification information read by the game coin tray reader / writer 362a that does not exist in the latest identification information stored in the game table storage device 364, for such game coin 72, the game table comparison device 363, like the above-mentioned cashier comparison device 333, compares whether the identification information is stored in the database 326 and confirms whether the usability status corresponding to the identification information in the database is "valid".

[0114] Specifically, the game table comparison device 363 usually compares the game coin ID read from the RFID tag 721 of the game coin 72 with the latest game coin ID in the past registered in the game table storage device 364. When a game coin 72 with a new game coin ID that was not read previously is read, the identification information including the tag ID read from the RFID tag 721 of the game coin 72 is compared with the identification information including the tag ID recorded in the database 326.

[0115] Figure 6 Flow chart of the operation of the game table system in the embodiment of the present invention. The antenna 361a and the game coin tray reader / writer read the game coin ID from the RFID tag 721 of all the game coins 72 in the game coin tray 36a (step S61). The game table comparison device 363 compares the combination of these read game coin IDs with the combination of game coin IDs stored as the latest game coin ID in the past in the game table storage device 364, and determines whether there is a new game coin ID among the read game coin IDs that is not stored in the game table storage device 364 (step S62).

[0116] When a new game coin ID is read ("Yes" in step S62), the antenna 361a and the game coin tray reader / writer 362a specify the new game coin ID, read the tag ID from the RFID tag 721 of the game coin 72 having the new game coin ID, send the combination of the game coin ID and the tag ID to the procedure room system 320, and compare it with the information stored in the database 326 (step S63). In addition, the game table storage device 364 stores the combination of all the read game coin IDs as a new combination of past game coin IDs (step S64).

[0117] It should be noted that when the game table comparison device 363 does not read a new game coin ID, that is, when no new game coin 72 has been added to the game coin tray since the last read, it determines whether there is a game coin ID that was read in the previous read but not read in this read by comparing the combination of the read game coin ID and the combination of the latest game coin ID in the past stored in the game table storage device 364 (step S65).

[0118] When there is an unread game coin ID, that is, when the game coin 72 is taken out from the game coin tray ("Yes" in step S65), the game table storage device 364 is made to store the combination of all the read game coin IDs as the combination of the latest game coin ID in the past (step S64). On the other hand, when there is no unread game coin ID ("No" in step S65), that is, when there is no increase or decrease or change in the game coin 72 in the game coin tray, the game table storage device 364 is not updated.

[0119] As such, in this embodiment, in the coin tray of the game table 36, the coin ID stored in the EPC area 212 is usually read at a predetermined time interval to monitor its change. When the coin ID changes, especially when a new coin ID is read, the coin 72 with the new coin ID is compared with the database 326 and the usability status of the database 326 is confirmed. This can reduce the processing burden and shorten the processing time required for one cycle (the processing speed can be increased).

[0120] It should be noted that, regardless of whether there is a newly read game coin ID, the game table comparison device 363 can compare with the database 326 and confirm the usability status of the database 326 at a specified time and / or under specified conditions.

[0121] When placing a game, the player 74 places the game coin 72 in a prescribed placement area on the game table. The antenna 361b is arranged below the placement area on the game table surface of the game table, and the game coin reader / writer 362b reads the identification information from the RFID tag 721 of the placed game coin 72. The identification information read by the game coin reader / writer 362b is compared by the game table comparison device 363 and stored in the game table storage device 364. When a plurality of game coins 72 are placed in the placement area, the game table storage device 364 stores a plurality of identification information corresponding to the plurality of game coins 72.

[0122] The antenna 361b and the coin reader / writer 362b not only read the coin 72 placed in the placement area by the player 74, but also read the RFID tag 721 of the coin 72 paid out from the coin tray by the dealer 75, and the game table storage device 364 also reads the RFID tag 721 of the coin 72 paid out in this way.

[0123] The game table comparison device 363 also performs confirmation of the usability status and comparison of the identification information for the identification information read from the RFID tag 721 by the game coin reader / writer 362b, similarly to the game coins 72 stored in the game coin tray. Specifically, for the identification information read by the game coin reader / writer 362b, the game table comparison device 363 does not always compare with the database 326, but when new identification information that does not exist in the latest identification information in the past stored as information read by the game coin reader / writer 362b in the game table storage device 364 is read by the antenna 361b and the game coin reader / writer 362b, the comparison is performed with the identification information stored in the database 326 and the usability status stored in the database 326 is confirmed via the central comparison device 323.

[0124] It should be noted that, in this embodiment, it is assumed that when the registration device 325 newly registers a new game coin 72, the usability status is registered as "valid", but it is not limited to this. From registration to transportation to the game pool 302, when it is kept in the background for a long time, the usability status is temporarily registered as "invalid". Before being transported to the game pool 302 or moved to the cashier's room 33, the usability status can be registered as "valid".

[0125] In addition, in the present embodiment, the registration device 325 performs the first verification and whether the usable state is changed to "valid" (activated), but the device (determination device) for the first verification and the device (registration device) for activating can be different devices. In addition, the first verification can be performed in the game coin manufacturing factory 200.

[0126] Furthermore, in the present embodiment, for the game coins 72 determined to be authentic through the first verification, a record is made in the database 326, and then, for the usable game coins 72, the usability status of the game coins 72 recorded in the database 326 is registered as "valid, but as an alternative, the database (usable database) can be composed only of usable game coins 72. In this case, the game coins 72 recorded in the usable database are judged to be usable. Furthermore, in addition to the usable database that records such usable game coins 72, a real game coin database of the game coins 72 determined to be authentic in the first verification can also be prepared. In this case, the game coins read at each game supplies processing position are compared with the usable database, and for the game coins 72 that are not recorded in the usable database, the real game coin database can be referenced to determine whether the game coin 72 is a game coin provided by the game coin manufacturing factory 200.

[0127] (Registration invalidated)

[0128] As described above, the registration device 325 registers the game coin 72 in the database 326 by storing various information including identification information of the new game coin 72 obtained from the factory in the database 326. On the other hand, for the faulty game coin 72 and the old game coin 72, the registration device 325 can temporarily invalidate the valid usability status.

[0129] In each game supplies processing position, the game coin 72 whose information is not read from the RFID tag 721 (i.e., the game coin 72 whose RFID tag 721 is damaged) is excluded from the usable game coins 72 on the spot. In addition, the game coin 72 whose identification information read from the RFID tag 721 fails to be checked is also excluded from the usable game coins 72 on the spot. Further, the game coin 72 whose usability status is non-valid is also excluded. The registration device 325 performs invalidation or activation procedures for these problematic game coins 72. Furthermore, for the game coins 72 that have no problems but have passed a specified period (e.g., 1 year) since the initial activation time and date, the invalidation procedure is performed to discard these game coins 72.

[0130] In the invalidation process, the registration device 325 updates the usability status of the game coin 72 recorded in the database 326 to "invalid", and records the update time and date. Alternatively, the registration device 325 can delete the information of the invalidated game coin 72 from the database 326. In the case where the RFID tag 721 of the game coin 72 fails, the identification information to be invalidated cannot be read from such a game coin 72. Therefore, the registration device 325 invalidates such a game coin 72 as described below.

[0131] Figure 7 A three-dimensional diagram of a game coin in a state where a decal is peeled off according to an embodiment of the present invention. The game coin 72 carries information for identifying the game coin 72 by a method other than an RFID tag 721. The game coin 72 has a circular recess in the center, and a decal 723 is attached to the bottom surface 722 of the recess. A number representing the value of the game coin 72 is marked on the decal 723. If the decal 723 falls off, the bottom surface (decal attachment surface) 722 thereof is marked with a game coin mark ID as the inherent identification information of the game coin 72. The game coin mark ID can be marked on the bottom surface 722 of the recess of the game coin 72 by laser engraving, or it can be printed on the decal attachment surface 722 by some ink. It should be noted that the game coin mark ID can be printed on the surface of the decal 723. In this case, visible ink or invisible ink that is invisible under normal conditions, such as UV luminescent ink that emits light when irradiated with UV light or infrared absorbing ink that absorbs infrared rays, can be used to print the game coin marking ID on the surface of decal 723.

[0132] For the game coin 72 whose identification information cannot be read from the RFID tag 721, the registration device 325 uses the game coin mark ID used to identify the game coin 72 to determine the identification information that should be invalidated for registration, and invalidates the registration. For the game coin 72 whose identification information cannot be read due to a malfunction of the RFID tag 721, when invalidating it, the operator removes the decal 723, visually confirms the game coin mark ID marked on the decal attachment surface 722, and inputs it into the registration device 325 via the input device 324. The registration device 325 refers to the database 326 to determine the identification information corresponding to the input game coin mark ID (refer to Figure 5 ). Thus, even if the RFID tag 721 is faulty, the game coin 72 can be identified on the database 326 and the procedure for invalidation can be performed.

[0133] As described above, the game coins 72 handed to the player 74 are placed by the player 74 or paid out by the dealer 75, and circulate among the multiple players 74 or the game tables 36, and finally return to the bank room 34 via the game table 35. At this time, as described above, the game coins 72 excluded from each game supplies processing position are invalidated by the registration device 325.

[0134] In addition, for the game coins 72 that have problems and are not excluded and are recovered in the bank room 34, the bank system 34 performs a comparison of identification information and confirmation of usability status, and further determines whether a prescribed period has not passed since the initial activation. At this time, if a game coin 72 whose identification information comparison fails, a game coin 72 whose usability status is not "valid", or a game coin 72 that has passed a prescribed period since the initial activation is detected, the procedure of invalidating these game coins 72 is performed.

[0135] It should be noted that, in each game supplies processing position, after comparing the read identification information with the database 326, if the result is a game coin 72 that is not registered in the database 326 and the game coin 72 whose usability status is not "valid", the registration device 325 can be immediately used to invalidate the game coin 72 without waiting for the game coin 72 to be returned to the backend 301. In addition, in the case where the usability status of the game coin 72 is "valid", the reader / writer at each game supplies processing position can rewrite its usability status to "invalid".

[0136] When the game coin 72 is read at each game supplies processing position, the central control device 323 can confirm the location history of the game coin 72 based on the information of the database 326. In the case where the location history record is inappropriate with reference to the prescribed judgment standard, the central control device 323 regards the game coin 72 as a suspicious game coin 72 and sets the usability status to invalid. For example, in the location history record, when the game coin 72 is directly moved from a certain player 74 to other players 74 without the game coin tray 36a, it is judged that the location history record of the game coin 72 is suspicious (there is the possibility of money laundering). Alternatively, a list (blacklist) of suspicious game coins 72 is pre-made on the database 326 side, and when the game coin 72 to be compared is listed in the blacklist, the registration device 325 can actually invalidate the game coin 72.

[0137] (Tracking of game coins)

[0138] As described above, the information of each game coin 72 in the database 326 includes the location history record information 266. The central comparison device 323 updates the location history record information 266 corresponding to the identification information every time it receives the comparison of the identification information from each game supply processing position. Specifically, when the central comparison device 323 receives the comparison of the identification information from each game supply processing position, it records the information that determines the game supply processing position as the location information in the location history record information 266 corresponding to the identification information, and records the time and date at that time as the reading time and date. In the database 326, a specified number of information can be recorded as the location history record information, and after the specified number of location history records are recorded, the old information is overwritten.

[0139] As described above, the location information is information for determining the location of the game supplies. For example, when the cashier's room 33 has multiple windows, the window ID for determining the window can be recorded as the location information. Since there are multiple game tables 35 and game tables 36, the game table ID and game table ID for determining which game table 35 and which game table are to be used can be recorded as the location information.

[0140] Furthermore, when the game coin 72 is handed over to the player 74, the player ID of the player 74 is recorded as the location information. For example, when the antenna 361b is provided for each player position of the game table 36, the player ID of each player position can be determined by the membership card held by the player 74 or by performing facial recognition on the image of the player playing the game at the game table 36.

[0141] And, by detecting which player position the game coin 72 paid to the player is paid to, it is possible to grasp the player of which player ID the game coin 72 is paid to. In addition, when the player 74 purchases the game coin 72 in the cashier's room 33, the player ID of the player 74 is determined, and the player ID is recorded as the location information.

[0142] In this way, by recording the history of the location information and the information of the time and date of reading in the database 326, it is possible to understand how the game coin 72 is moved simply by referring to the database 326.

[0143] (Variation 1)

[0144] Figure 8 The block diagram shows the structure of the procedure room system of the first modification of the embodiment of the present invention. The procedure room system 320′ of the first modification simultaneously activates a plurality of game coins 72. The plurality of game coins 72 are activated while being stored in a game coin box 71. The game coin box 71 is attached with a barcode 722, i.e., box identification information for identifying the game coin box 71.

[0145] In the data file 73 provided to the casino 300 by the manufacturer of gaming supplies, information of each token 72 corresponds to code information represented by the barcode 722. The office system 320' further includes a barcode reader 327. The barcode reader 327 reads the barcode 722 of the token box 71 storing the activated tokens 72.

[0146] The antenna 321 and the activation reader / writer 322 simultaneously read the RFID tags 721 of the plurality of game coins 72 stored in the game coin box 720. The plurality of identification information read from the RFID tags 721 of the plurality of game coins 72 by the antenna 321 and the activation reader / writer 322, the information of the data file 73′ decrypted by the input device 324, and the code information of the barcode 722 of the game coin box 71 read by the barcode reader 327 are input into the registration device 325. The registration device 325 first determines whether the code information of the game coin box 71 provided by the manufacturer of the game coins 72 and the code information of the game coin box 71 read by the barcode reader 327 are consistent. That is, the registration device 325 first determines whether the game coin box 71 itself is the game coin box that should exist there.

[0147] Next, the registration device 325 determines the identification information of the game coin 72 corresponding to the code information of the barcode 722, that is, determines the multiple activated game coins 72, based on the data file 73'. The registration device 325 compares the identification information of the determined game coin 72 with the identification information read from the RFID tag 721 of the activated game coin 72 by the activation reader / writer 322, thereby determining the authenticity of these game coins 72. When all the activated game coins 72 are successfully compared, the registration device 325 regards the usability status of these game coins 72 as "valid", stores the information of these game coins 72 in the database 326, and thus registers these game coins 72.

[0148] According to this structure, the game coins 72 can be stored in the game coin box 720 and managed from the time of manufacturing to activation, thereby ensuring that there is no excess or shortage of the game coins 72 to be stored in each game coin box 720.

[0149] (Variation 2)

[0150] Fig. 9 This is a block diagram showing the structure of the procedure room system of the second variant example of the embodiment of the present invention. The procedure room system 320″ of this second variant example can also activate multiple game coins 72 at the same time. The game coins 72 store types of information other than identification information. The procedure room system 320″ includes: a camera 3291, which photographs the sides of multiple game coins 72 whose RFID tags 721 are read through the antenna 321; and an image recognition device 3292, which performs image recognition on the image generated by the camera 329.

[0151] The plurality of game coins 72 are photographed by the camera 329 in a stacked state. The camera 3291 generates image data by photographing. The image recognition device 3292 performs image recognition on the image data, thereby determining the types of the plurality of game coins 72 based on the patterns displayed on the side thereof. Figure 2 As shown, the side of the game coin 72 has a center line as a pattern, and the color of the center line indicates the type of the game coin 72. Therefore, the image recognition device 3292 recognizes the center line from the image and determines the type of the game coin 3292 in the image based on its color.

[0152] The registration device 325 determines whether the types of the multiple game tokens read by the activation reader / writer 322, that is, the number of each type, and the types of the multiple game tokens recognized by the image recognition device 3292, that is, the number of each type, are consistent.

[0153] According to this structure, for the game coins 72 involved in activation, it can be checked whether the type determined by appearance is consistent with the type stored in the RFID tag 721. In addition, it can also be checked whether the number of game coins 72 obtained by appearance is consistent with the number of RFID tags 721 read.

[0154] It should be noted that in this second modification, the type of the game coin 72 is determined based on its appearance, and whether it is consistent with the type stored in the RFID tag 721 is determined. However, the type can also be determined without using an image and an RFID tag 721. Instead, the image recognition device 3292 recognizes the number of coins based on the image, and determines whether the number is consistent with the number of coins read from the RFID tag 721 by the activation reader 322, to check the game coin 72. In addition, in this second modification, for multiple game coins 72, these game coins can be checked one by one instead of checking them at the same time.

[0155] It should be noted that in the above-mentioned modification example 1, for the multiple game coins 72 stored in the game coin box 720, the identification information and other information of the game coins 72 stored in the game coin box 720 are obtained by reading the RFID tag 721. On the other hand, the barcode 722 is read by the barcode reader 327 and the data file 73′ is referred to, so as to obtain the identification information and other information of the game coins 72 stored in the game coin box 720, and the obtained information is compared to check the game coins 72. In addition, in the above-mentioned modification example 2, for the multiple game coins 72, the types of the game coins 72 are obtained by reading the RFID tag 721. On the other hand, the side of the multiple game coins 72 is photographed by the camera 329 for image recognition, so as to obtain the types of the game coins 72 stored in the game coin box 720, and the obtained information is compared to check the game coins 72.

[0156] As another example, the game coins 72 may be checked by using the number of game coins 72 stored in the game coin box 720 instead of using the barcode reader 327 or the camera 329. That is, since the procedure room system 320 uses a known game coin box as the game coin box 720, the number of game coins 72 stored in the game coin box 720 is known, and the game coins 72 can be checked by confirming whether the number of RFID tags 721 read by the antenna 321 and the activation reader / writer 322 is the known number.

[0157] In addition, the operator of the activation procedure can also check based on the information input from the operating device 328 instead of the camera 3291 and the image recognition device 3292. For example, the operator can visually check the multiple game coins 72 to determine the type information of these game coins and input it into the input device. In this case, the registration device 325 can also check the game coin 72 by determining whether the type information of the game coin 72 input by the operator to the operating device 328 and the type information read from the RFID tag 721 of the game coin 72 by the activation reader / writer 322 are consistent.

[0158] Furthermore, the registration device 325 can check the game token 72 by determining whether the type information input by the operator to the operation device 328 is consistent with the type information recorded in the data file 73 provided by the manufacturer of the game items.

[0159] In the procedure room system 320″ of the above-mentioned second variant and its variant, the number of game coins 72 determined by using the RFID tag 721, the number of game coins 72 determined by image recognition, the known number based on the game coin box 720, or the number input by the operator are compared for inspection. Through this inspection, game coins 72 with faulty RFID tags 721 (hereinafter referred to as "faulty game coins") can be detected. That is, the procedure room system 320″ can be used as an inspection device for detecting faulty game coins.

[0160] In the procedure room 32 of the backstage 301, in addition to detecting the faulty game coins on the game coins 72 being activated, the game coins 72 supplied to any game table 35 of the game pool 302 and the game coins 72 returned to the backstage 301 by depositing after being used in the game pool 302 can also be detected for the faulty game coins. In addition, the same inspection device as the procedure room system 320" is set in the cashier's room 33, and the game coins 72 sold to players from the cashier's room 33 and the game coins 72 exchanged for cash in the cashier's room 33 can also be inspected for faulty game coins.

[0161] Furthermore, the same inspection device as the procedure room system 320″ is set at the game table 35, and the game coins 72 transported from the backstage 301, the game coins 72 deposited from the game table 35 to the backstage 301, the game coins 72 supplied from the game table 35 to the game table 36, and the game coins 72 moved from the game table 36 to the game table 35 can also be inspected for faulty game coins.

[0162] The registration device 325 can invalidate the game coins 72 that are damaged by the inspection in this way. When the above inspection is performed during replenishment or deposit, replenishment or deposit is performed on the basis of confirming that the game coins 72 replenished or deposited are not damaged. In addition, when the above inspection is performed during exchange, exchange is performed on the basis of confirming that the game coins 72 to be exchanged are not damaged.

[0163] Furthermore, during replenishment and deposit, the game coins 72 moved between the game table 35 and the backstage 301 are inspected for faulty game coins, and damaged game coins 72 can be detected. In this case, the same inspection device as the procedure room system 320" can be set on the shelf (truck) used to transfer the game coins 72.

[0164] It should be noted that in the above-mentioned embodiment and the first and second modified examples, a game table 35 for managing a plurality of game tables 36 is provided in the game pool 302. When replenishing, the game coins 72 are supplied from the bank room 34 of the backstage 301 to the game table 36 via the game table 35. When depositing, the game coins 72 are transported from the game table 36 to the bank room 34 of the backstage 301 via the game table 35. However, the game table 35 may not be provided. When the game table 35 is not provided, replenishment and deposit are directly performed between the bank room 34 and each game table 36. In addition, in this case, the inspection performed at the game table 35 is changed to be performed at the game table 36.

[0165] (Variant 3)

[0166] In the above embodiment, the usability status is stored in the database 326 and the RFID tag 721 built into the game coin 72 as activation information, but the activation information may not be recorded in the RFID tag 721. In addition, the activation information may not be recorded in the database 326, and a table containing only activated and valid game coins 72 may be made in the database 326, and the central comparison device 323 determines whether the game coin 72 is an activated and valid game coin 72 based on whether there is identification information corresponding to the identification information read from the RFID tag 721 of the game coin 72 to be compared in the table.

[0167] (Variant 4)

[0168] In the above-mentioned embodiment Figure 3 and Figure 5 In the example, although the location history information is stored in the database 326, the location history information can also be recorded in the RFID tag 721 of the game coin 72.

[0169] In the game coins based on the prior art, the information written into the storage area can be grasped by reading the RFID, and the authenticity of the game coins themselves can be determined. However, it is not possible to record and determine the information obtained during the on-site use in the casino, especially the information related to the owner of the game coins. Therefore, for the game coins that are genuine but have abnormal historical records in terms of usage status, such as being used or exchanged by an owner different from the original owner, their existence cannot be grasped by reading the RFID, and it is impossible to prevent the use of such game coins with suspicious usage history records in the casino.

[0170] Therefore, the present invention aims to provide a system in which, in order to constantly grasp and manage the owner information of each game coin and improve security, when the dealer pays the game coin to the player and the owner of the game coin is transferred from the casino to the player, it is possible to grasp and record which player the owner of the game coin is transferred to.

[0171] (first example)

[0172] use Fig.10 , to explain the overall outline of the tabletop game management system of the first example of variation four. Fig.10 1 is a diagram showing the overall overview of the same system. A game table 1004 for a certain card game has a placement area for a player 1441, a banker 1442, a tie 1443, a player pair 1444, and a banker pair 1445 at each player position 1131 to 1135. In addition, a game coin arrangement area 1025 is provided for each player position, and a game coin reading device 1002 for reading the RFID of the game coin 1001 placed in the game coin arrangement area is provided.

[0173] Furthermore, each game coin arrangement area 1025 is provided with a payment area 1026 for placing game coins 1001 taken out from the game coin tray 1009 of the game table 1004 when the dealer pays the winning player with game coins 1001 from the game coin tray 1009 .

[0174] Furthermore, there is also a control device 1003, which grasps the reading result of the RFID of the game token 1001 read by the game token reading device 1002.

[0175] The player who starts the game places the game coin 1001 in the placement area in the game coin configuration area. The game coin reading device 1002 reads the RFID of the placed game coin 1001, so that the control device 1003 grasps the information related to the owner of the game coin 1001 associated with the ID information of the RFID in the database.

[0176] Based on the result of the game, when the casino wins, the dealer collects the game coins 1001 placed by the losing player and puts them into the game coin tray 1009. The RFID of the game coins 1001 in the game coin tray 1009 is grasped by the game coin reading device 1002, and the owner of the game coins 1001 collected by the casino is recorded in the database by the control device 1003.

[0177] Based on the result of the game, the dealer pays the winning player an amount of coins 1001 corresponding to the amount of the placed coins from the coin tray according to the game rules.

[0178] When making a payment, the game coins for payment can be placed in the above-mentioned payment area 1026, or in the game coin configuration area outside the payment area.

[0179] Among them, using Fig.11 , a method for recording the owner information of paid game coins is explained. Fig.11 , a method of recording information related to the owner of the game coin 1001 when the game coin is paid to the winning player is shown.

[0180] When multiple players place game coins in the same player position and there are more than two piles, the game coin reading device 1002 reads the game coins 1001 placed in the game coin configuration area 1025 together. Therefore, in the game, it is not known which game coin 1001 belongs to which player, and the ID 1010 of the placed game coins is obtained. After the winning or losing result of the game is determined, when the winning player is paid, the dealer pays each player (each pile) from the game coin tray 1009. The game coins 1001 taken out from the game coin tray 1009 are placed in the game coin configuration area 1025. The game coin reading device 1002 reads the ID 1011 of the payment game coin placed in the game coin configuration area 1025.

[0181] The paid game coin 1001 is received by the winning player together with the initially placed game coin 1001. At this time, the placed game coin and the paid game coin are moved outside the game coin configuration area 1025, so the IDs of the placed game coin and the paid game coin disappear from the reading result of the game coin reading device 1002. Thus, the control device 1003 understands to which player the paid game coin is paid by associating it with the information related to the owner of the placed game coin.

[0182] The control device 1003 stores the acquired information on the owner of the gaming token in the database in association with the ID of the gaming token.

[0183] As described above, the owner of the game token 1001 can be tracked, and in the case where there is an improper delivery of the game token 1001, it can be found that the owner information stored in the database is different from the actual owner.

[0184] It should be noted that the actual owner can be identified using facial recognition technology or an ID such as a membership card.

[0185] In the above description, the ID of each token is managed on the database, but the owner information may be stored in the token 1001 itself.

[0186] In addition, the above-mentioned payment area 1026 may be formed in a manner independent of each player position, in addition to being present at each player position, or may be read by the token reading device 1002 independently.

[0187] In addition, it can also be configured so that it is possible to choose whether to use the payment area 1026 or not to use the payment area 1026 according to the reading performance of the game coin reading device 1002.

[0188] In addition, the desktop game management system can also be configured to be combined with an RFID reader that reads the game coins in the game coin tray 1009 through RFID, a camera that reads the placed game coins, a card shoe that determines the winning or losing results of the game, etc., to utilize information mutually.

[0189] (Second example)

[0190] First, the game coins used in the game coin management system of the second example of Modification 4 are described. Fig.12 A gaming coin 1 used in the same system is shown. In the same figure, the gaming coin 1 is embedded with an RFID tag 2 capable of storing various information. The RFID tag 2 includes a non-rewritable data area 21 and a rewritable data area 22.

[0191] The non-rewritable data area 21 stores information that is not changed or unchanged during the use of the game coin 1, or information that cannot be changed, as fixed information 3. Specifically, the production information, product information, casino information, amount information, serial number, etc. of the game coin 1 are stored as fixed information 3. The production information includes the time and date of manufacturing the game coin, the manufacturing machine, etc., and the product information includes, for example, information indicating the game coin used in the VIP area of ​​the casino, information indicating the type of the game coin (for example, information indicating whether it is a transfer code or a cash code), etc.

[0192] The non-rewritable data area 21 may be an area that is non-rewritable due to the specifications or functions of the RFID tag, or may be an area that is locked to prevent writing after necessary information is written into the writable area.

[0193] The rewritable data area 22 stores information that changes during the use of the game coin 1 as the change information 4. For example, as the change information 4, Fig.12 As shown, location-related information 220 including information 221 related to time, date, and time, information 222 related to a place and an event, and information 223 related to an owner is stored.

[0194] The fixed information 3 and the variable information 4 can be encrypted to prevent others from illegally reading or writing the information. In addition, the fixed information 3 and the variable information 4 can be stored as metadata.

[0195] Fig.13 An example of a method for recording data of the change information 4 of the game coin 1 is shown. Fig.13 As shown, the structure is to use the location-related information 220 including time and date, time information 221, place, event information 222, and owner information 223 as a block, connect the block information into a chain, and grasp the historical record of the location-related information 220 of the game coin 1.

[0196] exist Fig.13 , an example of the change information 4 stored in the game coin 1 is shown, and the movement of the game coin 1 shown below can be grasped. At 16:02 on January 28, 2019, Mr. A exchanged cash for the game coin 1 at the counter 5. At 16:15 on the same day, Mr. A used the game coin 1 to place a bet at the game table No. 325. At 16:43 on the same day, Mr. B received the game coin 1 at the game table No. 325 as a compensation for winning the bet. At 17:01 on the same day, Mr. B left the casino with the game coin 1.

[0197] like Fig.13 As shown, the change information 4 can be configured to store only the latest information, or to store all the location-related information written. In addition, several of the multiple location-related information can be selected for storage. When several are selected for storage, multiple location-related information including at least the latest location-related information 220 can be stored in all the location-related information 220. According to the above structure, the use or movement history of a certain game coin 1 can be known based on the change information 4 of the game coin 1. That is, it can be configured that the tracking information of the game coin 1 is written into the game coin 1 itself and is mastered.

[0198] Next, the management system of the gaming coins 1 of this example will be described. Fig.14An overall overview of the same system is shown.

[0199] In the game coin 1, first, the change information 4 including the information of the manufacturing completion or the factory shipment is written into the rewritable data area 22 of the RFID tag 2 as the location-related information 220 at the factory 6 by the writing device 14.

[0200] In the background 7 of the casino, the processing of receiving the game coins 1 shipped from the factory 6 is implemented. In the background 7, the reading device 13 reads the change information 4 stored in the rewritable data area 22 of the game coin 1. Based on the reading result, the management control device 15 determines whether the information 220 related to the location written in the factory 6 as the information to be written is written as the latest change information 4. Assuming that there is no write record in the factory 6, an error signal is generated as a game coin suspected of being improper. Thus, the casino side can refuse to receive the game coin and entrust the factory side to investigate. If there is no problem with the write record, the information 220 related to the location of the background is written into the rewritable data area 22 of the RFID tag 2 by the writing device 14. When writing, the location information of the factory can be added and the location information of the background can be recorded, or the location information of the factory can be deleted and the location information of the background can be recorded. In addition, the reading or writing of the game coins in the above-mentioned background 7 can be carried out together with the usual verification or activation operation of the game coins.

[0201] The game coins 1 received and checked in the backstage 7 are transported to the warehouse 8 or counter 9 of the casino. In the warehouse 8 or counter 9, the reading device 13 reads the change information 4 stored in the rewritable data area 22 of the game coin 1. Based on the reading result, the management control device 15 determines whether the location-related information 220 written in the backstage 7 as the information to be written is written as the latest change information 4. In addition, it can be checked at the same time whether the information indicating the factory 6 is written in the historical record indicating the change information 4. The management control device 15 determines whether there is no abnormality in the historical record of the location information, similar to the above-mentioned check performed in the backstage 7. If there is no problem with the reading result, the writing device 14 writes the location-related information 22 indicating the warehouse 8 or counter 9 into the rewritable data area 22.

[0202] The player purchases a game coin 1 at the counter 9. When the player purchases the game coin 1, the time when the game coin was purchased and the information that the owner of the game coin has changed from the casino to the guest are written as the change information 4 by the writing device 14 located at the counter 9. The player can be identified and recorded by facial recognition technology or an ID card such as a casino membership card or identity card.

[0203] The player uses the game coin 1 to be exchanged and places the game coin 1 in the placement area 11 on the game table. The reading device 13 reads the location-related information 220 including the time and date, time information 221, or the location, event information 222, or owner information 223 from the RFID tag 2 of the placed game coin 1, and the management control device 15 determines whether there is an abnormality. For example, if a certain period of time has passed since the time and date of the last written use information at the game table or the exchange information at the counter, and the owner information 223 stored in the game coin 1 is different from the owner information 223 determined by facial recognition or ID card, it can be determined as an abnormality.

[0204] When there is no problem in reading, for the placed game coin 1, the writing device 14 writes the information 220 related to the location to the rewritable data area 22. The information 220 related to the location includes time and date, time information 221, location, event information 222, and owner information 223. On the game table, for example, the change information 4 including the player position number and the player's information of the placed game coin 1 is written by the writing device 14. The player's information can be determined by an ID card or facial recognition. Usually, the game coins 1 are stacked and placed in the placement area 11, and therefore, they are written together in a stacked state.

[0205] When a player takes a game coin 1 out of the casino game pool, the exit process is performed at the entrance 10. When exiting, the information 220 related to the location is read by the reading device 14, and the change information 4 is determined to be abnormal by the management control device 15. In addition, at the entrance 10, the writing device 14 writes the change information 4 including the location indicating the exit, event information 222, and owner information 223.

[0206] When a player enters a casino game pool and brings in a previously taken-out game coin 1, the reading device 13 reads the information related to the location, and the management control device determines whether there is any abnormality in the change information 4. For example, for a game coin 1 that has been taken out of the casino, if the owner at the time of exiting the casino is different from the owner at the time of entry, it can be determined that there is an act of delivering the game coin outside the casino.

[0207] In the case where the reading result of the reading device 13 is determined to be abnormal, the management control device 15 can output an alarm to the counter 9 or the entrance 10. When the owner of the game coin 1 exchanges the game coin at the counter 9 or exits the entrance 10, he can refuse to exchange the game coin based on the alarm output by the management control device 15, or conduct individual inspection when exiting the game coin. In addition, in the case where the judgment result is abnormal, the management control device 15 can make the following judgments: issue a warning to the dealer of each game table to interrupt the game, or issue a warning to the game table, and the game table manager determines whether to interrupt the game or continue the game; exchange the game coin 1, etc. Alternatively, the management control device 15 can be configured to be connected to the overall management control device 18 of the casino and issue a warning to all management control devices 18.

[0208] Similar to the management control device 15, when exchanging at the counter, the change information 4 can be read by the reading device 13 to determine abnormality. Specifically, it can be determined as abnormal if a certain period of time has passed since the time and date of the last written use information at the game table or the exchange information at the counter, or if a person different from the owner information 223 stored in the game coin 1 attempts to exchange. If it is determined to be abnormal, the management control device 15 can output a warning and refuse to exchange the game coin 1 determined to be abnormal.

[0209] Furthermore, in the above description, the writing device 14 performs writing after the reading device 13 performs reading and the management control device performs determination. However, the reading and writing may be performed simultaneously.

[0210] The following shows details of an application example of this embodiment.

[0211] In the factory 6, when production is completed or shipped, the RFID tag 2 is read and / or written. Production information and product information are written as fixed information 3, locked so that they cannot be rewritten as needed, and variable information 4 is written.

[0212] In the background 6, when the game coin 1 shipped from the factory is received as a usable game coin 1 and activated, the RFID tag 2 is read and / or written.

[0213] In the warehouse 8, when the game coin 1 is moved from the warehouse 8 to the counter 9, or when the game coin 1 is moved from the counter 9 to the warehouse 8, the RFID tag 2 is read and / or written. Alternatively, for the game coin 1 stored in the warehouse 8, the RFID tag 2 can be read and / or written at fixed intervals or at a specified time.

[0214] At the counter 9, the RFID tag 2 is read and / or written when the money is moved from or to the warehouse 8 and when the customer's cash and game coins 1 are exchanged. When the exchange is performed at the counter 9, the place where the exchange is performed, event information 222, and the player information performing the exchange are written as owner information 223 in the change information 4. The owner information 223 can be obtained from the player's casino ID card, facial recognition system, credit card, etc.

[0215] At the entrance and exit 10, when a player enters or exits, the RFID tag 2 is read and / or written. When a player exits, all game coins 1 taken out of the casino are registered by writing the place and event information 222 indicating the taken out, and the owner information 223 indicating the taken out player as the variable information 4. When entering the casino, the game coins 1 brought into the casino are also registered by writing the place and event information 222 indicating the brought in, and the owner information 223 indicating the brought in player as the variable information 4.

[0216] In the placement area 11, the RFID tag 2 is read and / or written to the game coin 1 placed in the placement area 11 by the player to participate in the placement. In addition, the RFID tag 2 is read and / or written to the game coin 1 placed in the placement area 11 by the dealer as a compensation to the player.

[0217] In the coin tray 12 , the RFID tag 2 is read and / or written for the coins 1 collected in the coin tray or the stored coins 1 .

[0218] The gaming table further includes a payment area 2007 and a payment area 1026, and the RFID tag 2 can be read and / or written for the gaming coin 1 placed in the placement area 11 by the dealer as a repayment to the player.

[0219] The management control device 15 has a function of determining whether there is no abnormality in the location-related information 220 obtained from the reading result of the reading device 13 at each location. As a determination of whether there is an abnormality, it can be determined whether there is any event that the location-related information that should be written has not been used for more than a predetermined period since the last writing or has not been written.

[0220] Events where the device has not been used for a specified period of time after the last write include any of the following conditions:

[0221] 1) The latest location-related information is the information indicating the counter 9, and the next information is written after a specified time;

[0222] 2) The latest location-related information is information indicating entry at the entrance 10, and the next information is written after a specified time has passed;

[0223] 3) The latest location-related information is information indicating exit at the entrance 10, and the next information is written after a predetermined time has passed.

[0224] The event that the information related to the location that should be written is not written includes any of the following situations:

[0225] 4) When entering the amusement park, the rewritable data area 22 of the game coin 1 is not written with information related to the latest location, and the information indicating exit at the entrance 10 is not written;

[0226] 5) When the counter 9 is used, the information indicating the backstage 7 is not written;

[0227] 6) When exiting the amusement park, information indicating the counter 9 or the backstage 7 is not written.

[0228] The management control device 15 can determine any one of the following conditions as an event for determining whether an abnormality occurs based on the information 223 related to the owner acquired from the reading device 13:

[0229] 1) A person who is different from the final owner stored in the rewritable data area 22 exchanges the game coin 1 for cash or makes an exchange in the amusement park, or exits the amusement park;

[0230] 2) A person who is different from the owner of the token stored in the rewritable data area 22 at the time of exiting the game brings the token into the casino.

[0231] The management control device 15 determines any one of the following 1) to 4) based on the information indicating the location of the placement area 11, the location of the coin tray 12, or the information indicating the payment area obtained from the reading device 13 as an event to determine whether it is abnormal:

[0232] 1) A person who is different from the final owner stored in the rewritable data area 22 uses the game coin 1 at the game table;

[0233] 2) The game coin 1 which has no usage record at the game table is exchanged at the counter 9 by a person who is different from the person who purchased the game coin 1 at the counter 9;

[0234] 3) Using game coins 1 without information indicating the counter 9 or the backstage 7 in the amusement park;

[0235] 4) The latest location-related information is information indicating the placement area 11 or the payment area, which is exchanged at the counter 9 or used at the game table after a prescribed period of time.

[0236] Fig.17 The database of another example of the modification example 4 is shown. The management system also has a database 17 that records the same fixed information 3 and variable information 4 in addition to the game coin 1. The management control device 15 can record the information in the database 17 based on the reading result of the reading device 13, and compare the fixed information 3 and variable information 4 stored in the game coin 1 with the information in the database to determine abnormalities.

[0237] In the RFID tag 2 in this example, the area of ​​the non-rewritable data area 21 that cannot be functionally written can be the TID. The area that is locked so that data cannot be written after necessary information is written to the non-rewritable data area 21 can be the EPC or the user area. The rewritable data area 22 can be the EPC or the user area.

[0238] The reading device 13 and the writing device 14 can change their forms according to the location. Fig.15 The device on the table shown is box-shaped at the entrance 10, and at the placement area 11 or the game coin tray 12, the placement area 11 or the game coin tray 12 itself can have the functions of the reading device 13 and the writing device 14. In addition, the game coins 1 can be directly stacked, and can be read and / or written in a state of being stored in a game coin box, etc. In addition, the reading device 13 and the writing device 14 can be formed as one.

[0239] In the above fourth variation, the case where the game coin has one RFID tag, and the single RFID tag has a non-rewritable data area and a rewritable data area is described. In contrast, the following method can also be considered, that is, two RFID tags are placed in the game coin, one RFID tag is locked on the basis of storing fixed information so that data cannot be written, and the other RFID tag is set to rewritable data for recording variable information.

[0240] However, in this case, when reading multiple game coins together, such as Fig.16A As shown, the information group of fixed information 3 and the information group of variable information 4 are read separately. Therefore, there will be a problem that it is impossible to determine the combination of fixed information and variable information of a certain game coin, and it is impossible to determine the game coin with abnormal variable information.

[0241] In this regard, when there is only one RFID tag, Fig. 16B As shown, even when reading multiple game coins together, since the reading device can grasp the correspondence between the fixed information and the variable information read, it is considered better to implement a single RFID tag.

[0242] In addition, generally speaking, the larger the diameter of the RFID tag, the higher the reading accuracy. Therefore, when the RFID tag is placed in the game coin, the RFID tag is preferably a size with a diameter at least larger than the radius of the game coin. However, since two RFID tags are placed in the game coin, the smaller the diameter of each RFID tag, the more preferably. In addition, if two RFID tags are placed, the number of RFID tags to be read increases, thus causing the reading speed to decrease when reading multiple game coins.

[0243] Based on the above points, it is believed that the effect of implementing it through a single RFID tag is better.

[0244] (Third example)

[0245] Hereinafter, the overall outline of a management system for table games in a casino having a plurality of game tables according to a third example of Modification 4 will be described. Fig.18 As a diagram representing the overall overview of the same system, a management system for tabletop games in an amusement park having multiple game tables 2004 comprises: a game recording device 2011, which records games played on the game tables 2004 including game coins 1 as images using multiple cameras 2002; an image analysis device 2012, which performs image analysis on the recorded images; a game coin reading device 25, which reads the RFID attached to the game coin 1; and a game result determination device 18, which determines and displays the game results of each game on the game table 2004.

[0246] The game result determination device 18 is, for example, a card issuing device 2003, which is a so-called electronic card shoe that has been used by those skilled in the art. It can be configured such that the game rules are pre-programmed, the information of the issued cards C is read, and the winning or losing of the game is determined. For example, in a certain card game, the winning of the banker, the winning of the player, and the tie (draw) are basically determined by the face value of 2-3 cards, and the determination result (winning or losing result) is displayed by the result display light 2013.

[0247] In the same figure, the game table 2004 is a card game table, which is provided with 5 seat numbers 13 ("Seat number 1" 131, "Seat number 2" 132, "Seat number 3" 133, "Seat number 5" 134, "Seat number 6" 135), and 5 game participants can participate in the game. A placement area 44 is provided for each seat number 13. The placement area 44 of the seat number 13 includes areas for the player (PLAYER) 441, the banker (BANKER) 442, the tie (TIE) 443, the player pair (P) 444, and the banker pair (B) 445. Each game participant places a game coin 1 of the placement amount at the position corresponding to the placed object, thereby playing the game. In Fig.19For example, two coins 1 are placed on the tie 443 of seat number 5, and two coins 1 are placed on the player 441. The game table 2004 is provided with a player card area 45 for placing the drawn player cards, and a dealer card area 46 for placing the drawn dealer cards.

[0248] The control device 2014 can grasp where each player 2006 places the game coin 1 in the placement area 2008 (whether it is the player, the banker, the tie, or the pair), the type of the game coin 1 (the game coin 1 has a different amount of value according to each color) and the number of the game coins 1 placed by using the camera 2002 and the image analysis device 2012. That is, for example, it can be grasped that two game coins 1 are placed in the tie 443 of seat number 5 and two game coins are placed in the player 441.

[0249] like Fig.18 As shown, the game coin reading device 25 is configured to read the RFID of the game coin 1 present in the reading area together with the entire placement area as a reading area according to each seat number. The RFID attached to the game coin 1 is written with inherent ID information, the amount, type, manufacturing information, owner information, etc. of the game coin 1. Alternatively, in the database, the amount, type, manufacturing information, owner information, etc. of the ID information and the game coin 1 can be stored in association. The game coin reading device 25 can grasp the game coin 1 according to each seat number by reading the RFID attached to the game coin 1, and can grasp the total amount or number of pieces. That is, for example, 4 game coins are placed at the seat number 5, and the respective types, amounts, and IDs of the game coins can be grasped.

[0250] like Fig.19 As shown, the control device 2014 obtains the total amount or total number of game coins 1 for each seat number from the types and numbers of game coins 1 placed in each placement area of ​​each seat number based on the image analysis result of the image analysis device 2012, and compares it with the total amount or total number of game coins 1 for each seat number obtained based on the RFID information of the game coins 1 read by the game coin reading device 25 to determine whether they are consistent. Furthermore, the seat number determined to be inconsistent can be output, and the problematic seat number can be determined.

[0251] If the total amount or total number of game coins 1 for each seat number obtained based on the reading result of the game coin reading device 25 is smaller than the total amount or total number of game coins 1 for each seat number obtained based on the image analysis result of the image analysis device, it is possible that the RFID attached to the game coin 1 is damaged and cannot be read, or the game coin 1 has no RFID attached. Fig.19In the figure, regarding the game coin 1 placed in seat number 1, the total number of reads obtained by the image analysis of the image analysis device 2012 is 4, while the total number of reads obtained by the RFID reading of the game coin reading device 25 is 3. Therefore, for the game coin 1 placed in seat number 1, it can be considered that the RFID of one of the four coins cannot be read.

[0252] Compared with the total amount or total number of game coins 1 for each seat number obtained based on the image analysis result of the image analysis device, if the total amount or total number of game coins 1 for each seat number obtained based on the reading result of the game coin reading device 25 is larger, it can be considered that the game coins 1 may enter the blind spot of the camera, so the image analysis device 2012 cannot read the game coins 1. Fig.19 In the example, regarding the game coin 1 placed at seat number 3, the total number of reads obtained based on the image analysis of the image analysis device 2012 is 1, while the total number of reads obtained based on the RFID reading of the game coin reading device 25 is 2. Therefore, it is possible that there may be two game coins 1 placed at seat number 3, but the image analysis device only recognizes one.

[0253] The ID information of the RFID attached to the game coin 1 is registered in the database of the casino, and records the production and shipment information in the factory, or the reception, verification, and activation information in the casino. The control device 2014 can compare the information of the RFID read by the game coin reading device 25 with the information in the database to determine the authenticity of the game coin registered as a game coin to be used in the casino.

[0254] According to this structure, the type and number of game coins 1 placed in each placement area are grasped by the camera, and based on the RFID information of the game coins 1 read by the game coin reading device 25, the authenticity of the game coins 1 is determined to be improper or bad for each seat number.

[0255] In addition, the system is also equipped with a game participant identification mechanism using a facial recognition system or a player ID card, and the control device 2014 can associate the game participant information identified by the game participant identification mechanism with the seat number. The control device 2014 can store the deposit amount, repayment or recovery amount, and winning and losing information stored for each seat number for each game participant. In addition, the game participants can collectively store multiple games played at multiple game tables.

[0256] The control device 2014 can use the game coin tray determination device 12 to determine the total amount of game coins 1 in the game coin tray 17 of the dealer 2005 of the game table 2004. After the game is over and settled, the control device 2014 can compare and calculate whether the total amount of game coins 1 in the game coin tray 17 has increased or decreased according to the recovery of the lost game coins 1 placed by each player 2006 and the payment 9W of the winning game coins of the winning player 2006W. The game coin tray determination device uses the camera 2002 to shoot the game coins 1 stored in the game coin tray 17, and grasps the total amount of game coins 1 in the game coin tray 17 based on the analysis of the image analysis device. By setting an RFID reading device on the game coin tray 17, the total amount of game coins 1 stored in the game coin tray 17 is detected.

[0257] In this example, cheating or errors are detected based on the winning or losing results of the game, information on which type of game coins 1 is placed at which position in the placement area 2008 (player, banker, tie, pair), and the increase or decrease in the amount of game coins 1 in the game coin tray 17 after the recovery of lost game coins and the repayment of won game coins 1. Therefore, even if the movement of the game coins 1 after the game is over is not known, that is, whether the placed game coins 1 move to the player side or to the dealer side, cheating or errors can be detected.

[0258] Among them, for example, in the case of a certain card game, in the card issuing device 2003, by reading the face value of the card C drawn in the game, the winning or losing result of the game can be determined according to the rules of the card game. In addition, the game table 2004 is photographed by the camera 2002, the image analysis device 2012 analyzes the image, and the analysis result is compared with the game rules by the control device 2014, so that the winning or losing result of the game can also be determined. In this case, the camera 2002, the image analysis device 2012 and the control device 2014 constitute a game result determination device. The information of how many and what kind of game coins 1 the player of each seat number 7 places in which position (player, banker, tie, player pair, banker pair) in the placement area 2008 is obtained by the following method: the game coins 1 placed in the placement area 2008 are photographed by the camera 2002, and the image analysis device 2012 analyzes the image for each player position 7.

[0259] In addition, by comparing the total amount of game coins 1 in the game coin tray 17 before the recovery of lost game coins 1 and the repayment of won game coins 1, and the total amount of game coins 1 in the game coin tray 17 after the recovery of lost game coins 1 and the repayment of won game coins 1, the increase or decrease in the amount of game coins 1 in the game coin tray 17 before and after the recovery of lost game coins 1 and the repayment of won game coins 1 can be calculated.

[0260] For example, the total amount of game coins 1 in the game coin tray 17 before the game starts is set to Bb, and the total amount of game coins 1 in the game coin tray 17 after the game ends and the recovery of lost game coins and the repayment of won game coins are completed is set to Ba. In addition, in this game, the total amount of game coins 1 placed in the player area in all player positions 7 is bp, the total amount of game coins 1 placed in the banker area in all player positions 7 is bb, and the total amount of game coins 1 placed in the tie area in all positions 7 is bt. For example, in the case where the winning or losing result of the game is the banker wins, Ba-Bb=bp-bb+bt should be established. Alternatively, the total amount Ba of game coins 1 in the game coin tray 17 after the game ends should be (Bb+bp-bb+bt). If this is not the case, it can be determined that there is cheating or error in the recovery or repayment of game coins.

[0261] Fig.23A This is a diagram showing the details of the coin tray of this example. Fig. 23B 1 is a diagram showing another example of a game coin tray. The game coin tray 17 is provided with a recovery game coin tray 171 for recovering and temporarily storing the game coins 1L placed by the losing player 2006L, and a repayment game coin tray 172 for storing the game coins 1W for repayment. The image analysis device 2012 and the control device 2014 grasp the position, type and number of the game coins 1L placed by the losing player 2006L, and calculate the amount of increase of the game coins 1L in the game (the amount of game coins 1 in the recovery game coin tray 171). Furthermore, the image analysis device 2012 and the control device 2014 grasp the actual total amount of the game coins 1 in the recovered game coin tray 171, compare the total amount that should be there with the actual total amount, and determine whether there is a difference.

[0262] The control device 2014 can also compare the total amount of the game coin tray obtained based on the amount of game coins to be repaid in the game and the actual total amount in the game coin tray when the corresponding game coin 1 is repaid and the repayment is completed, and determine whether there is a difference between the total amount and the actual total amount, wherein the amount of game coins to be repaid is calculated based on the position, type and number of game coins placed by each game participant on the game table and the game results.

[0263] Furthermore, by using the game coin 1 in the redemption game coin tray 172 to redeem the game coin 1W of the winning player 2006W, sufficient time can be ensured for the image analysis device 2012 and the control device 2014 to grasp the actual total amount of the game coins 1 in the recovered game coin tray 171 after recovery.

[0264] As described above, in the third example, the control device 2014 calculates the income and expenditure of game coins in each game based on the amount of game coins placed on the game table 2004 and the winning or losing results of the game, and detects the increase in the balance of game coins in the game coin tray 17 after the game. If a difference is detected in this detection, the control device 2014 issues an alarm or adds a record indicating the situation to the image record taken by the camera 2002. The casino operator can find out the cause of the difference by confirming the image.

[0265] The management system of the tabletop game in the third example adds or subtracts the increase or decrease in the game coins in the game calculated based on the positions, types and numbers of the game coins 1 placed by all the players 2006 in the game and the winning or losing result of the game obtained by the winning or losing result determination device, from the total amount of game coins 1 in the game coin tray 17 before each game is cleared, and compares the expected total amount of game coins 1 in the game coin tray 17 after clearing at the end of the game with the actual total amount of game coins 1 in the game coin tray 17 at the end of the game obtained by the image analysis device 2012 to determine whether there is a difference between the expected total amount and the actual total amount.

[0266] The control device 2014 uses the image analysis device 2012 to grasp the position, type and number of game coins placed by each player. When all the lost game coins placed by each player are recovered, the control device 2014 grasps the actual total amount of game coins in the game coin tray, compares the expected total amount of game coins 1 in the game coin tray 17 with the actual total amount of game coins 1 in the game coin tray 17, and determines whether there is a difference between the expected total amount and the actual total amount, wherein the expected total amount of game coins 1 in the game coin tray 17 is obtained by adding the total amount of game coins in the game coin tray before each game is cleared, plus the increase in the game coin tray 17 in the game obtained according to the position, type and number of game coins placed by the losing player.

[0267] The control device 2014 compares the total amount of game coins 1 in the game coin tray 17 before the settlement of each game, the expected total amount of game coins 1 in the game coin tray 17 calculated by adding the increase in the game coin tray 17 in the game obtained according to the position, type and number of game coins 1 placed by the losing player, and the actual total amount of game coins 1 in the game coin tray 17. If it is determined that there is no difference between the expected total amount and the actual total amount, and compares the expected total amount in the game coin tray 17 after actuation at the end of the game with the actual total amount of game coins 1 in the game coin tray 17 at the end of the game obtained by the image analysis device 2012, and if it is determined that there is a difference between the expected total amount and the actual total amount, a payment error is determined, and a payment error signal for notifying the payment error is issued.

[0268] The game coin tray 17 is provided with a recovery game coin tray 171 for recovering and temporarily storing the game coins 1 placed by the losing player. The image analysis device 2012 compares the expected total amount of game coins 1 in the recovery game coin tray 171 obtained by adding the increase in the game coins 1 in the game calculated according to the position, type and number of the game coins 1L placed by the losing player, with the actual total amount of game coins 1 in the recovery game coin tray 171 to determine whether there is a difference between the expected total amount and the actual total amount.

[0269] The control device 2014 determines that there is a discrepancy between the actual total amount of game coins 1 held in the game coin tray 17 of the dealer 2005 of the game table 2004 and the increase or decrease in the amount of game coins calculated based on the amount of game coins placed by all players and the winning or losing results of the game. The game recording device 2011 adds an index or time to the acquired image, or determines and reproduces the recovery scene or payment scene of the game coins 1, so that the game records that produce the above-mentioned differences can be analyzed in the game recording device 2011.

[0270] In this way, the control device 2014 obtains the total amount of game coins in the game coin tray 17 after settlement at the end of the game through the image analysis device 2012. The judgment after settlement in this case can be performed under any of the following 1) to 4).

[0271] 1) When the repayment of the won game coin 1 is completed;

[0272] 2) When the card C used in the game is collected and discarded to the discard area 41 or the discard slot 42 of the game table;

[0273] 3) When a prescribed button attached to the winning or losing result determination device is pressed;

[0274] 4) Restore the mark 43 indicating winning or losing.

[0275] In addition, the control device 2014 is an artificial intelligence effective utilization type or deep learning structure as follows: the position (placed at the position of the player, the banker, and the pair) and the amount (type and number) of the game coins placed on each player position 7 of the game table 2004 are grasped, and the winning and losing history records of each player 2006 and the amount of game coins obtained (the amount won) obtained from the winning and losing results of each game are compared with the statistical data of the majority of games in the past (big data), and extracted as abnormal conditions (set by the casino). Typically, the control device 2014 with the artificial intelligence effective utilization type or deep learning structure as follows: the winning amount of more than a certain amount (1 million points) is generated, or the state in which the number of game coins placed when losing is small and the number of game coins placed when winning is large at the player position 7 of a certain game table 2004 continues for several games, which can be compared with the past game statistical data (big data, etc.) and extracted as abnormal conditions.

[0276] Furthermore, the control device 2014 of the management system of the present table game is a structure (integrated with the image analysis device 2012) capable of extracting abnormal conditions or determining individual players 2006 at the player position 7 who have won more than a specified amount. Such determination of players 2006 can be determined in advance in the image analysis device 2012 by extracting feature points from the facial image and attaching an identification card number (ID, etc.). In addition, the control device 2014 has a warning function of notifying the other game table of the existence of the determined player when the determined player 2006 leaves and sits at another game table. Specifically, the game table manager or the person in charge of each game table (who may be the dealer) who manages each game table 2004 is notified to prevent more abnormal phenomena.

[0277] The control device 2014 can determine the recovered game coins 1 for each seat number based on the RFID ID information of the recovered game coins 1 determined by the game coin tray determination device and the RFID ID information of the game coins 1 read by the game coin reading device 25.

[0278] exist Fig. 20 In Fig.21 and Fig. 22 As shown in the detailed table, game coins 1 are placed. In the analysis of the image analysis device 2012, the place (player, banker, etc.) where the game coins 1 are placed and the number of coins (and the amount) can be grasped. On the other hand, in the reading of the game coin reading device 25, the RFID ID of the game coin 1 attached to each seat number can be grasped. Furthermore, the game coin tray determination device can determine the ID of the game coin 1 in the game coin tray 9, and therefore, the ID added before and after the recycling can be grasped, so that the recycled game coins 1 can be grasped. In Figures 20-22 When the game result is that the dealer wins, from the analysis results of the image analysis device 2012, it can be seen that the two game coins placed on the dealer's pair should be recovered. It can be seen that among the IDs of the recovered game coins determined by the game coin tray determination device, the two coins ID6 and ID18 placed on seat number 5 read by the game coin reading device 25 are recovered.

[0279] The control device 2014 also grasps the total amount or total number of game coins 1 to be recovered for each seat number determined using the game result obtained from the game result determination device and the measurement result of the position, amount and number of game coins 1 based on the image analysis result of the image analysis device. Therefore, the control device 2014 can compare the total amount or total number of game coins 1 recovered for each seat number determined based on the RFID with the total amount or total number of game coins 1 to be recovered based on the image analysis result to determine whether they are consistent.

[0280] For example, when the reading result of the game coin reading device 25 of seat number 1 is "A, B, C, D, E", the analysis result of the image analysis device 2012 is "2 coins placed in a tie, 2 coins placed by the dealer", the game result is "dealer wins", and the reading result of the game coin tray judgment device 18 is "A, B", it can be seen that the A and B game coins placed in the tie are correctly recovered.

[0281] The control device 2014 can also determine whether the ID information of the RFID of the recovered game coin 1 determined by the game coin tray determination device is consistent with the ID information of the RFID of the placed game coin 1 read by the game coin reading device 25. Based on this determination, it can be determined whether the game coin 1 recovered by the game coin tray is the game coin 1 placed on the game table, or the game coin 1 illegally recovered from other places.

[0282] The control device 2014 can also determine the type of game coins such as cash codes, conversion codes, promotion codes, etc. based on the RFID information read by the game coin reading device 25, and can store the amount placed, recovered or repaid according to the determined type of game coins.

[0283] The transcode is a special game coin that can be purchased by a certain member and cannot be exchanged for cash. For the transcode, the amount purchased by each member is managed. It must be placed for consumption, and the repayment of the transcode placed is repaid by the cash code. The amount of transcode placed or recovered is stored based on the RFID information read by the game coin reading device 25, so that the amount of transcode that a certain member should hold can be grasped.

[0284] The game coin reading device 25 also has the function of confirming the area and can read the game coins 1 placed for repayment. Fig.24 As shown, in the case of redeeming the dealer of seat number 2, a game coin 1 for redemption is placed in the game coin reading device 25 and read. Fig.24 The winning game coin 1 placed by the dealer in seat number 2 is placed next to the winning game coin 1. The control device 2014 compares the repayment amount determined by the measurement results of the position, amount and number of game coins 1 based on the game result obtained from the game result determination device and the image analysis result of the image analysis device with the amount of the game coins 1 placed in each seat number based on the reading result of the game coin reading device 25, determines whether the repayment amount is consistent or inconsistent, and outputs it. Fig.25In the example, the total number of game coins 1 to be paid for seat number 1 is 4, but the reading result of the game coin reading device 25 is 3, which is inconsistent. In the case of inconsistent repayment amounts, an inconsistent signal is output, and the dealer can re-place the game coins 1 for repayment based on the output signal. In the case of re-placing the game coins 1, a determination can be made again and the determination result can be output. The area where the game coins 1 for repayment are placed can be any position in the game coin reading device 25. In addition, if Fig.24 As shown, the payment confirmation area 26 can be configured separately from the placement area on the dealer side of the placement area. Fig.24 In the process, the game coin 1 for repayment is placed in the payment confirmation area 26 of the seat number 6, the game coin reading device 25 reads it, and the control device 2014 determines and places the repayment game coin next to the winning game coin 1 placed on the dealer.

[0285] In addition, the image analysis device 2012 also performs image analysis on the confirmation area, and the control device 2014 can compare the reading results with the game coin reading device 25 to determine whether the total number of coins is consistent.

[0286] A signal can be output based on the determination made by the control device 2014. The signal can be output in the form of a display on the display portion of the coin tray 9 or the display portion of the card issuing device 13, and can be output to a game table manager or the backstage of the casino.

[0287] The game coin reading device 25 can be as follows Fig.26 As shown, the entire placement area is used as a reading area according to each seat number, or as Fig. 27 As shown, according to each seat number, the player placement area and the banker placement area are used as a fetching area, and the tie placement area, the player pair placement area, and the banker pair placement area are used as a reading area. Fig.28 , 31 As shown, the tie placement area, the player pair placement area, and the banker pair placement area may be placed sideways as one reading area.

[0288] The following describes the game coin 1 used in this example. Fig.29 This is the appearance of the game coin 1 used in this system. Fig.30: is a front cross-sectional view. A multilayer structure is formed in which a plurality of plastic layers of different colors are stacked, and at least a colored layer 101 is provided in the middle, and white layers 102 or light-colored layers (although not shown, any layer lighter in color than the colored layer 101) are stacked on both sides of the colored layer 101 in the middle. By forming a multilayer structure in which a colored layer 101 is provided, and a white layer 102 or light-colored layers (although not shown, any layer lighter in color than the colored layer 101) are stacked on both sides of the colored layer 101 in the middle, Fig.30 As shown, a stripe pattern is formed on the side in the stacking direction, and the color of the colored layer 101 (red, green, yellow or blue, etc.) can be changed to determine the type of the game coin 1 (10 points, 20 points, 100 points, 1000 points, etc.).

[0289] The coloring layer 101 is as follows Fig.31 The illustrated example may consist of multiple layers of coloring (in Fig.30 Because the colored multiple layers ( Fig.30 3 layers) are bonded to each other by heat compression, so that Fig.30 As shown, the three-layer structure is not in a state that can be visually confirmed. Fig.30 The three layers in the description are shown. Furthermore, a part of the layer in the center of the three layers of the coloring layer 101 is provided with a hollow portion B, in which an RFID is built.

[0290] In addition, the token 1 is not limited to a structure in which plastic layers are stacked, and may also have a structure that does not have the same appearance as the colored layer 101 .

[0291] The following is a detailed description of the method by which the image analysis device 2012 analyzes the game coin 1. The image analysis device 2012 performs image analysis on the image recorded by the recording device 11, and identifies at least two colors, namely, the determination color 121 at least partially attached to the game coin 1 and the reference color R different from the determination color 121 present in the image. It should be noted that the determination color 121 is at least partially attached to a specified position of the game coin 1 or at least partially attached in a specified shape. For example, it can be attached as a coloring layer 101, attached circumferentially to the side of the game coin 1, and attached to the surface of the game coin 1 as a specified mark. In addition, the reference color R can be, for example, the color of a specified area of ​​the game table 2004, or the color of a place different from the determination color 121 attached to the game coin 1.

[0292] The image analysis device 2012 includes an artificial intelligence device 12a that determines the color, for example, by deep learning (deep learning) technology, and determines the number and type of game coins 1 placed on the game table 2004. The recognition device 12 can also determine the position of the game coin 1 on the game table 2004.

[0293] The image analysis device 2012 obtains a plurality of images of the game coin 1 and the reference color R illuminated at different illuminations, and uses the obtained images and the correct colors of the definite color 121 and the reference color R of the game coin 1 in each image as teacher data for teaching by a person, thereby learning and making a learning mode 13a (recognition program). It should be noted that for the images of the game coin 1 and the reference color R illuminated at the same illumination conditions, by illuminating the definite color 121 and the reference color R with the same illumination, the relative relationship between the definite color 121 and the reference color R can be obtained. For example, this relative relationship can be used for the recognition of the definite color 121.

[0294] In addition, the game coin recognition device 12 can extract the center line C of the game coin 1 by shooting and recording the image with the camera 200212 instead of using artificial intelligence, and then using the result of image analysis to measure the features on the image such as shape, brightness, saturation, and hue.

[0295] The artificial intelligence device 12a also has the following structure: performing image analysis on the peripheral image of the specified range around the extracted center line C (for example, a range of 8 pixels centered on the center line and perpendicular to the center line, etc.), thereby identifying at least two colors in the peripheral image, namely, the determined color 121 and the reference color R different from the determined color 121. It should be noted that when performing image analysis on the peripheral image of the specified range around the extracted center line C, the image can be directly analyzed, or it can be analyzed after performing image processing such as color enhancement and noise removal, so that the identification of the determined color 121 becomes easy.

[0296] In summary, the artificial intelligence device 12a of the recognition device 12 is an artificial intelligence device as follows: it has a structure of extracting a center line C from the image of the game coin 1, performing image analysis on the peripheral image within a specified range centered on the center line C, thereby identifying at least two colors in the peripheral image, namely a determined color 121 and a reference color R different from the determined color 121, and using multiple peripheral images of the game coin 1 and the reference color R obtained by irradiating with different illuminations as teacher data for teaching.

[0297] In other examples, the control device 2014 further has the function of determining at least one of the following situations:

[0298] 1) In each game, whether there is no movement of game coins from the time a card is drawn or the dealer starts the game until the card issuing device displays the winning or losing result of the game;

[0299] 2) After each game is over, while the dealer collects the game coins placed by the losers among the game participants, whether no one other than the dealer moves the game coins;

[0300] 3) After each game is over, whether additional game coins are added during the period when the dealer collects the game coins placed by the losers among the game participants;

[0301] 4) After each game is over, whether the dealer pays the position of the game coin placed by the winner among the game participants;

[0302] 5) After each game is over, whether the winner among the game participants has taken away the placed game coins and the paid game coins.

[0303] Furthermore, the control device 2014 can be configured to use the analysis results of the image analysis device to detect the hand movements of the dealer and game participants, the movement of game coins, or the hand movements and the movement of game coins, thereby determining at least one of 1) to 5).

[0304] The control device 2014 has the following functions 1) to 5) according to the game rules of a certain card game, and as a characteristic function of the present invention, it determines whether cheating that violates the rules is performed. That is,

[0305] 1) In each game, from the time when the free card issuing device 2003 receives a card drawing start signal or the dealer 2005 presses the start button for 4 seconds to start the game until the card issuing device 2003 displays the winning or losing result of the game, the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether there is movement of the game coin 1;

[0306] 2) After each game is over and the dealer 2005 is collecting the game coin 1 placed by the loser among the game participants 2006, the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether the loser 6 has taken the game coin 1 improperly;

[0307] 3) After each game is over, while the dealer 2005 collects the game coin 1 placed by the loser among the game participants, the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether anyone other than the dealer 2005 (winner or loser) adds the winning game coin 1W or re-places a new game coin 1 to the winning side that has not been placed;

[0308] 4) After each game is over, the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether the dealer 2005 correctly places the game coin 1W to be paid at the position where the winner of the game participant 2006 places the game coin 1;

[0309] 5) After each game is over (the dealer 2005 operates the card issuing device 2003 to display the winning or losing results on the display light 13), the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether the winner 6W among the game participants 2006 has taken away the placed game coins 1 and the paid game coins 1W.

[0310] It should be noted that in the above example, the image analysis device 2012 and the control device 2014 are devices with artificial intelligence effective utilization or deep learning structures. Specifically, the image analysis device 2012 and the control device 2014 can use the scale-invariant feature transform (SIFT; Scale-lnvarant Teature Transform) algorithm, convolutional neural network (CNN; Convolutional Neural Network), deep learning (deep learning), machine learning (mechanical learning), or similar devices to perform image analysis or the above-mentioned various controls. These technologies are technologies for performing image recognition on captured images and identifying objects included in the images. In particular, in recent years, deep learning technology that multi-layers neural networks has been used to identify objects with high accuracy. This deep learning technology generally stacks layers in multiple levels in the intermediate layer between the input layer and the output layer of the neural network to identify objects with high accuracy. Among this deep learning technology, in particular, the convolutional neural network has higher performance than the previous image feature quantity based object recognition, so it has attracted attention.

[0311] In the convolutional neural network, the recognition target image with the label is learned, and the main object included in the recognition target image is identified. When there are multiple main objects in the learning image, the area rectangle is specified, and the image corresponding to the specified area is labeled for learning. Furthermore, in the convolutional neural network, the main object in the image and the position of the object can be determined.

[0312] Further explaining the convolutional neural network, in the object recognition step, edge extraction processing is performed on the recognition object image, so as to extract the candidate area based on the local features, and the candidate area is input into the convolutional neural network, and classification is performed based on the extracted feature vector, and the candidate area with the highest classification certainty factor is obtained as the recognition result. The certainty factor refers to the amount that indicates how much higher the similarity of the subject of the image that learns a certain image area and a label together is compared with the similarity of other levels.

[0400] an image analysis device for performing image analysis on the recorded image of the gaming coin;

[0401] a game coin reading device that reads the RFID attached to the game coin placed by each game participant; and

[0402] a control device that grasps the image analysis result of the image analysis device and the reading result of the game coin reading device,

[0403] The game table has a placement area, which includes a player placement area, a banker placement area, and a side placement area.

[0404] The side placement area is arranged adjacent to the placement area for each seat number.

[0405] The game coin reading device can collectively read at least one of the side placement areas,

[0406] The control device is configured to independently grasp the type and number of the game coins placed in at least one of the side placement areas based on the image analysis results of the image analysis device, determine whether the total amount or total number of game coins in the at least one side placement area based on the image analysis results of the image analysis device and the total amount or total number of game coins placed on the side based on the reading results of the game coin reading device are consistent, and output a signal of the determination result.

[0407] Furthermore, the control device may be configured to output the side placement whose determination result is inconsistent.

[0408] In addition, the control device can also be configured to generate a signal indicating that the RFID attached to the game coins may be damaged or that the RFID is not attached to the game coins when the total amount or the total number of game coins placed on each side based on the reading result of the game coin reading device is less than the total amount or the total number of game coins placed on each side based on the image analysis result of the image analysis device.

[0409] In addition, the control device can also be configured to generate a signal indicating the possibility of a reading error of the game coins by the image analysis device when the total amount or total number of game coins placed on each side based on the reading result of the game coin reading device is larger than the total amount or total number of game coins placed on each side based on the image analysis result of the image analysis device.

[0410] In addition, a database is provided, which stores the ID of the RFID attached to the game coin.

[0411] The control device may be configured to compare the ID of the RFID based on the reading result of the game token reading device with the ID stored in the database to determine the authenticity of the game token.

[0412] In addition, the control device can be configured to determine the recovered game coins placed on each side based on the ID information of the RFID of the recovered game coins determined by the game coin tray determination device and the ID information of the RFID of the game coins read by the game coin reading device, and compare the ID or amount or number of game coins to be recovered on each side determined using the measurement results of the position, amount and number of game coins with the ID or amount or number of game coins recovered on each side, so as to determine the consistency or inconsistency of the recovered amount for each side, wherein the measurement results of the position, amount and number of game coins are based on the game results obtained from the game result determination device and the image analysis results of the image analysis device.

[0413] In the case where there is only one game coin or game coin stack that is to be paid in one game coin reading device 25, the placed game coin can be paired with the payout game coin and associated with the owner information even if it is not detected whether the game coin has moved outside the area of ​​the game coin reading device 25. That is, in the case where there is one game coin 1001 or a stack of game coins consisting of several game coins 1001 in one game coin reading device 25, the placed game coin can be paired with the payout game coin and associated with the owner information based on the information that the payout game coin has disappeared from the game coin tray or the information of the payout game coin read by the game coin reading device 25 on the game table, even if it is not detected whether the game coin has moved outside the area of ​​the game coin reading device 25. Of course, it can be configured to identify the placed game coins based on the information that the game coins are moved to the area outside the game coin reading device 25, and use the information of the game coins taken out of the game coin tray, the information of the game coins placed in the placement area, and the information of the game coins moved to the area outside the game coin reading device 25 to pair the paid game coins with the placed game coins, thereby associating the information related to the owner of the paid game coins based on the owner information of the placed game coins. In addition, it can also be configured to read the ID of the game coins through RFID, and identify the type and number of game coins including the identification of the stack through a camera.

[0414] The situation that there is one game coin or game coin pile of the object to be paid in a game coin reading device 25 includes: at the time of placement, there is one game coin or game coin pile in the area, or at the time of placement, there are several piles, but in the payment, the pile becomes the last one. It can be configured to pair only the last pile of the placed game coins with the payment game coins and associate it with the owner information. In this case, the remaining last pile is set as the game coin placed by the member, so that the tracking of the game coins of the member can be carried out reliably. Preferably, there is one member to place in each game coin reading device (for example, each player position), and non-members can place by several people. In the case of one member in each player position, since the game coin is associated with the owner, the information of the member assigned to each player position can be grasped from the information of the placed game coin.
