Summary of the Invention

Problems to be Solved by the Invention

[0005] In the case of gaming tokens based on the prior art, it was possible to determine the authenticity of the gaming tokens themselves by grasping the information written in the memory area through RFID reading. However, it was not possible to record and determine the information obtained during use at the casino site, particularly information regarding the owner of the gaming tokens. Therefore, even though the gaming tokens are genuine, those with an abnormal history in terms of usage, such as being used or exchanged by an owner different from the original owner, cannot have their existence grasped by RFID reading, and it was not possible to prevent such gaming tokens with an abnormal usage history from being used at the casino.

[0006] Therefore, in the present invention, in order to constantly grasp and manage the owner information of each gaming token and enhance security, when a dealer pays a gaming token to a player and the ownership of the gaming token moves from the casino to a player, the present invention aims to provide a system that enables grasping and recording which player has acquired the ownership of the gaming token.

[0007] In order to solve the above-mentioned prior problems, the gaming token management system of the present invention comprises gaming tokens attached with individually identifiable RFID, a gaming table for playing games using the gaming tokens, in the gaming table, a chip placement area where betting chips wagered by players participating in the game and payout chips paid out by the dealer to winning players from the chip tray on the gaming table are placed, a chip reading device for reading the RFID of the gaming tokens placed in the chip placement area, and a control device for grasping the reading result of the chip reading device, and the control device can acquire information regarding the owner of the gaming token based on the ID information of the RFID of the gaming token, Furthermore, the control device recognizes that the bet chips of the winning player and the payout chips paid out to the winning player move outside the chip placement area, and is configured to be able to associate on a database the ID information of the payout chips with the ID information of the bet chips that have moved outside the chip placement area at the same timing as the payout chips. It has a function of associating on a database information regarding the owner of the bet chip indicated by the RFID of the bet chip with the ID information held by the RFID of the payout chip.

[0008] Furthermore, the chip placement area is configured to be partitioned for each player position, and includes a pay area for placing the payout chips for each player position. The chip reading device may be configured to be able to distinguish and read the pay area for each player position.

Embodiments for Carrying Out the Invention

[0010] (First Embodiment) The overall outline of the table game management system according to the first embodiment of the present invention will be described with reference to FIG. 1. FIG. 1 is a diagram showing the overall outline of the system. On the gaming table 1004 for baccarat games, there are betting areas for the player 1441, banker 1442, tie 1443, player pair 1444, and banker pair 1445 for each player position 1131 to 1135. In addition, a chip placement area 1025 is provided for each player position, and a chip reading device 1002 for reading the RFID of the gaming currency 1001 placed in the chip placement area is provided.

[0011] Furthermore, in each chip placement area 1025, there is a pay area 1026 for the dealer to place the gaming currency 1001 taken out from the chip tray 1009 when paying out the gaming currency 1001 to the winning player from the chip tray 1009 of the gaming table 1004.

[0012] Furthermore, a control device 1003 for grasping the RFID reading result of the gaming currency 1001 read by the chip reading device 1002 is further provided.

[0013] First, a player who starts to participate in the game bets the gaming currency 1001 in the betting area within the chip placement area. When the chip reading device 1002 reads the RFID of the bet gaming currency 1001, the control device 1003 grasps the information regarding the owner of the gaming currency 1001 associated with the ID information of the RFID on the database.

[0014] Based on the result of the game, if the casino wins, the dealer will collect the gaming currency 1001 wagered by the losing player and place it in the chip tray 1009. The RFID of the gaming currency 1001 in the chip tray 1009 is grasped by the chip reader 1002, and the control device 1003 records in the database that the owner of the gaming currency 1001 collected by the casino is the casino.

[0015] Based on the result of the game, for the winning player, the dealer pays out from the chip tray an amount of gaming currency 1001 corresponding to the amount of the wagered chips to the winning player according to the game rules.

[0016] When paying out, the payout chips may be placed in the above-mentioned pay area 1026, or may also be placed within the chip placement area other than the pay area.

[0017] Here, the method of recording the owner information of the payout chips will be described with reference to FIG. 2. FIG. 2 shows the method of recording information regarding the owner of the gaming currency 1001 when paying chips to the winning player.

[0018] When multiple players place wagered chips within the same player position and there are two or more stacks, since the chip reader 1002 reads the gaming currency 1001 placed in the chip placement area 1025 collectively, during the game, without knowing which gaming currency 1001 belongs to which player, the ID 1010 of the wagered gaming currency is obtained. After the win / loss result of the game is determined and a payout is made to the winning player, the dealer makes a payout from the chip tray 1009 for each player (for each stack). The gaming currency 1001 taken out from the chip tray 1009 is placed in the chip placement area 1025. The chip reader 1002 reads the ID 1011 of the payout chips placed in the chip placement area 1025.

[0019] The paid-out gaming currency 1001 is received by the winning player together with the initially wagered gaming currency 1001. At this time, since the wagered chip and the payout chip move outside the chip placement area 1025, the IDs of the wagered chip and the payout chip disappear from the reading result of the chip reading device 1002. Thereby, the control device 1003 grasps which player the paid-out payout chip has been paid out to by associating it with the information regarding the owner of the wagered chip.

[0020] The control device 1003 stores the information regarding the owner of the grasped payout chip in association with the ID of the gaming currency on the database.

[0021] As described above, the traceability of the owner of the gaming currency 1001 becomes possible, and in the case of illegal transfer etc. of the gaming currency 1001, it becomes possible to discover that the owner information stored in the database is different from the actual owner.

[0022] It should be noted that for the determination of the actual owner, it can be grasped by using ID such as face recognition technology or membership cards.

[0023] Also, in the above description, the IDs of each gaming currency are managed on the database, but a configuration in which the owner information is stored in the gaming currency 1001 itself may also be possible.

[0024] Also, the above-described pay area 1026 may be configured such that, in addition to being present for each player position, the area is configured independently of each player position, and the reading by the chip reading device 1002 is also performed independently.

[0025] Furthermore, depending on the reading performance of the chip reading device 1002, a configuration may be possible in which the pay area 1026 can be selected to be used or not used.

[0026] Furthermore, this table game management system may also be connected to an RFID reader that reads chips in the chip tray 1009, a camera that reads bet chips, a win / loss result determination device such as a shoe that determines the win / loss result of the game, etc., and may be configured such that information can be mutually utilized.

[0027] (Second Embodiment) First, the substitute gaming currency used in the management system of the substitute gaming currency according to the embodiment of the present invention will be described. FIG. 3 shows the substitute gaming currency 1 used in the system. In the figure, an RFID tag 2 capable of storing various information is embedded in the substitute gaming currency 1. The RFID tag 2 includes an area 21 where data cannot be rewritten and an area 22 where data can be rewritten.

[0028] In the area 21 where data cannot be rewritten, as fixed information 3, information that does not change, or information that has not changed, or information that must not be changed during the use of the substitute gaming currency 1 is stored. Specifically, as the fixed information 3, production information, product information, casino information, amount information, serial number, etc. of the substitute gaming currency 1 are stored. The production information includes the date and time when the substitute gaming currency was manufactured, the manufacturing machine, etc. The product information includes information indicating that the chip is for the VIP area of the casino, information indicating the type of chip (e.g., information indicating that it is a rolling chip or a cash chip), etc.

[0029] The area 21 where data cannot be rewritten may be an area where writing is functionally impossible due to the specifications of the RFID tag, or may be an area that is locked so that data cannot be written after writing the necessary information in the area where writing is possible.

[0030] In the area 22 where data can be rewritten, as variable information 4, information that changes while the gaming substitute currency 1 is being used is stored. For example, as variable information 4, as shown in FIG. 3, location-related information 220 including information 221 regarding date and time, information 222 regarding location and event, information 223 regarding the owner, etc. is stored.

[0031] The fixed information 3 and variable information 4 may be encrypted to prevent unauthorized reading and writing of information by others. Also, the fixed information 3 and variable information 4 may be stored as metadata.

[0032] FIG. 4 shows an example of a method for recording data of the variable information 4 of the gaming substitute currency 1. As shown in FIG. 4, the location-related information 220 consisting of the date and time, time information 221, location, event information 222, and owner information 223 is regarded as a single block, and the information of the block is connected in a chain so that the history of the location-related information 220 of the gaming substitute currency 1 can be grasped.

[0033] FIG. 4 shows an example of the variable information 4 stored in the gaming substitute currency 1, and the movement of the gaming substitute currency 1 as follows can be grasped. At 16:02 on January 28, 2019, Mr. A exchanges cash and the gaming substitute currency 1 at Cage 5. At 16:15 on the same day, Mr. A uses the gaming substitute currency 1 to place a bet at Table No. 325. At 16:43 on the same day, Mr. B receives the gaming substitute currency 1 as the repayment for winning the bet at Table No. 325. At 17:01 on the same day, Mr. B leaves the casino with the gaming substitute currency 1.

[0034] The variable information 4 may be configured to store only the latest information as shown in FIG. 4, or may store information regarding all the locations where it has been written. Further, some of the information regarding a plurality of locations may be selectively stored. When selectively storing some of them, a plurality of pieces of information regarding locations including at least the information 220 regarding the latest location among the information 220 regarding all the locations may be stored. With the above configuration, the history of use or movement of a specific game substitute currency 1 can be understood from the variable information 4 of the game substitute currency 1. That is, the traceability information of the game substitute currency 1 is written in the game substitute currency 1 itself and is configured to be graspable.

[0035] Next, the management system for the game substitute currency 1 of the present embodiment will be described. FIG. 5 shows an overall overview of the system.

[0036] First, in the factory 6, the game substitute currency 1 has variable information 4 including information on manufacturing completion or factory shipment written by the writing device 14 into an area 22 where the data of the RFID tag 2 can be rewritten as information 220 regarding the location.

[0037] The gaming substitute currency 1 shipped from the factory 6 is subject to acceptance processing in the casino's backyard 7. In the backyard 7, the reading device 13 reads the variable information 4 stored in the area 22 where the data of the gaming substitute currency 1 can be rewritten. Based on the reading result, the management control device 15 determines whether the location-related information 220 indicating that it has been written at the factory 6 is written as the information to be written as the latest variable information 4. If there is no writing record at the factory 6, an error signal is generated as gaming substitute currency suspected of being fraudulent. As a result, it becomes possible to reject the acceptance of the gaming substitute currency on the casino side or to request an investigation from the factory side. If there is no problem with the writing record, the writing device 14 writes the location-related information 220 indicating the backyard into the area 22 where the data of the RFID tag 2 can be rewritten. At the time of writing, the location information indicating the backyard may be described in addition to the location information indicating the factory, or the location information indicating the factory may be deleted and the location information indicating the backyard may be described. Also, the reading and writing of the gaming substitute currency in the above-mentioned backyard 7 can be performed in conjunction with the normal validation and activation operations of the gaming substitute currency.

[0038] The gaming substitute currency 1 for which the acceptance inspection has been completed in the backyard 7 is transported to the casino's warehouse 8 or cage 9. In the warehouse 8 or cage 9, the reading device 13 reads the variable information 4 stored in the area 22 where the data of the gaming substitute currency 1 can be rewritten. Based on the reading result, the management control device 15 determines whether the location-related information 220 indicating that it has been written in the backyard 7 is written as the information to be written as the latest variable information 4. Also, it may be checked whether information indicating the factory 6 is written in the history of the variable information 4. Similar to the inspection in the above-mentioned backyard 7 by the management control device 15, it is determined whether there is an abnormality in the history of the location information. If there is no problem with the reading result, the writing device 14 writes the location-related information 22 indicating the warehouse 8 or cage 9 into the area 22 where the data can be rewritten.

[0039] The player purchases the game substitute currency 1 at the cage 9. When the player purchases the game substitute currency 1, the writing device 14 in the cage 9 writes, as the fluctuation information 4, the time when the game substitute currency was purchased and information indicating that the owner of the game substitute currency has changed from a casino staff to a customer. The player may be configured to be identified and recorded by face recognition technology, an ID card such as a casino membership card or a My Number card, etc.

[0040] The player uses the exchanged game substitute currency 1 and places the game substitute currency 1 in the bet area 11 on the gaming table to place a bet. The reading device 13 reads, from the RFID tag 2 of the bet game substitute currency 1, the location-related information 220 consisting of date and time, time information 221, location, event information 222, and owner information 223, and the management control device 15 determines whether there is any abnormality. For example, it can be determined as abnormal when a certain period of time has passed since the date and time of the information on use at the gaming table or the information on exchange at the cage written last, or when the owner information 223 stored in the game substitute currency 1 is different from the owner information 223 identified by face recognition or an ID card.

[0041] When there is no problem with the reading result, for the bet game substitute currency 1, the writing device 14 adds the location-related information 220 to the area 22 where data can be rewritten. The location-related information 220 includes date and time, time information 221, location, event information 222, and owner information 223. On the table, for example, the fluctuation information 4 including the player position number where the game substitute currency 1 is placed and the player's information is written by the writing device 14. The player's information may be identified by an ID card or face recognition. Usually, since multiple game substitute currencies 1 are stacked and placed in the bet area 11, the writing is performed collectively in the stacked state.

[0042] When a player takes out the gaming substitute currency 1 from the casino floor, the player undergoes the exit process at Gate 10. At the time of exit, the location-related information 220 is read by the reading device 14, and the management control device 15 determines whether there is any abnormality in the fluctuation information 4. Also at Gate 10, the writing device 14 writes the location indicating exit, the event information 222, and the fluctuation information 4 including the owner information 223.

[0043] When a player brings in the gaming substitute currency 1 that was taken out previously when entering the casino floor, the location-related information is read by the reading device 13, and the management control device determines whether there is any abnormality in the fluctuation information 4. For example, regarding the gaming substitute currency 1 that has once been taken out of the casino, if the owner at the time of exit from the casino is different from the owner at the time of entry, it can be grasped that there has been an act of transferring the gaming substitute currency outside the casino.

[0044] When the determination based on the reading result of the reading device 13 by the above-described management control device 15 is abnormal, the management control device 15 may output an alarm to the cage 9 or Gate 10. When the owner of the gaming substitute currency 1 exchanges it at the cage 9 or exits from Gate 10, the redemption can be refused or individual checks can be performed at the time of exit based on the alarm output by the management control device 15. Also, when the determination result is abnormal, the management control device 15 may issue a warning to interrupt the game to the dealers at each gaming table, issue a warning to the pit, and the pit manager may make a judgment such as interrupting or continuing the game, or may make a judgment on countermeasures such as exchanging the gaming substitute currency 1. Alternatively, the management control device 15 may be connected to the overall management control device 18 of the casino and may be configured to issue a warning to the overall management control device 18.

[0045] Similarly, when cashing in is performed using the cage, the management control device 15 may read the variation information 4 by the reading device 13 and determine abnormalities. Specifically, an abnormality may be determined when a certain period or more has elapsed since the date and time of the information on use at the gaming table or the information on cashing in using the cage, which was last written, or when a person different from the owner information 223 stored in the gaming substitute currency 1 attempts to cash in. When an abnormality is determined, the management control device 15 may output a warning and reject the cashing in of the gaming substitute currency 1 for which the abnormality has been determined.

[0046] Also, in the above description, the form in which writing is performed by the writing device 14 after reading by the reading device 13 and determination by the management control device has been described, but a configuration in which reading and writing are performed simultaneously may also be used.

[0047] Hereinafter, details of an application example of the present invention will be shown.

[0048] At the factory 6, reading and / or writing of the RFID tag 2 is performed at the time of completion of production or at the time of shipment. Production information and product information are written as fixed information 3, locked so that rewriting is not possible as necessary, and variation information 4 is written.

[0049] In the backyard 6, when receiving the gaming substitute currency 1 shipped from the factory and activating it as a usable gaming substitute currency 1, reading and / or writing of the RFID tag 2 is performed.

[0050] At the warehouse 8, when moving the gaming substitute currency 1 from the warehouse 8 to the cage 9 or when moving the gaming substitute currency 1 from the cage 9 to the warehouse 8, reading and / or writing of the RFID tag 2 is performed. Alternatively, reading and / or writing of the RFID tag 2 may be performed on the gaming substitute currency 1 stored in the warehouse 8 at regular intervals or at a predetermined timing.

[0051] In the cage 9, when moving from or to the warehouse 8, and when exchanging the customer's cash for the gaming tokens 1, the RFID tag 2 is read and / or written. When cashing is performed in the cage 9, the location indicating the cashing, the event information 222, and the player information who cashed are written as the owner information 223 into the variable information 4. The owner information 223 can be obtained from the player's casino ID card, face recognition system, credit card, etc.

[0052] At the gate 10, when the player enters or exits, the RFID tag 2 is read and / or written. For all the gaming tokens 1 taken out of the casino when the player exits, the location indicating the taking out, the event information 222, and the owner information 223 indicating the player who takes out are written as the variable information 4 for registration. Similarly, when entering, the location indicating the bringing in, the event information 222, and the owner information 223 indicating the player who brings in are written as the variable information 4 for registration of the gaming tokens 1 brought into the casino.

[0053] In the bet area 11, the RFID tag 2 is read and / or written for the gaming tokens 1 placed in the bet area 11 for the player to participate in the bet. Also, the RFID tag 2 is read and / or written for the gaming tokens 1 placed in the bet area 11 by the dealer as the repayment to the player.

[0054] In the chip tray 12, the RFID tag 2 is read and / or written for the gaming tokens 1 collected in the chip tray and the gaming tokens 1 stored.

[0055] The gaming table further includes a payment area including the area 2007 and the pay area 1026. The RFID tag 2 may be read and / or written for the gaming tokens 1 placed in the bet area 11 by the dealer as the repayment to the player.

[0056] The management control device 15 has a function of determining whether there is an abnormality in the location-related information 220 obtained from the reading results of the reading device 13 at each location. As the determination of whether there is an abnormality, it is possible to determine whether there is any event such as that it has not been used for a predetermined period or longer since the previous writing, or that the location-related information that should have been written is not written.

[0057] The event that it has not been used for a predetermined period or longer since the previous writing is 1) The information regarding the location is the information indicating cage 9, and the writing of the next information has taken a predetermined time or longer. 2) The information regarding the location is the information indicating entry at gate 10, and the writing of the next information has taken a predetermined time or longer. 3) The information regarding the location is the information indicating exit at gate 10, and the writing of the next information has taken a predetermined time or longer. It is any of the above situations.

[0058] The event that the location-related information that should have been written is not written is 4) When entering the game arcade, as the information regarding the latest location of area 22 where the data of the game substitute currency 1 can be rewritten, the information indicating exit at gate 10 is not written. 5) When using cage 9, the information indicating backyard 7 is not written. 6) When exiting the game arcade, the information indicating cage 9 or backyard 7 is not written. It is any of the above situations.

[0059] Based on the owner-related information 223 obtained from the reading device 13, as an event for the management control device 15 to determine whether there is an abnormality, 1) A person different from the final owner stored in area 22 where data can be rewritten exchanges, exchanges, or exits the game arcade with the game substitute currency 1 inside the game arcade. 2) A person different from the owner at the time of leaving the game, who is stored in the rewritable area 22 of the data, brings the game substitute currency into the game hall. It is possible to determine any of the following situations.

[0060] Based on the information indicating the location of the bet area 11 obtained from the reading device 13, or the location of the chip tray 12, or the information indicating the payment area, the management control device 15 determines whether it is abnormal as an event. 1) A person different from the final owner stored in the rewritable area 22 of the data uses the game substitute currency 1 on the game table. 2) A person different from the person at the time of purchase of the game substitute currency 1 in the cage 9 of the game substitute currency 1, which has no usage record on the game table, exchanges it in the cage 9. 3) The game substitute currency 1 without information indicating the cage 9 or the backyard 7 is used in the game hall. 4) The information regarding the latest location is the information indicating the bet area 11 or the payment area, and after a predetermined period has elapsed, it is exchanged in the cage 9 or used on the game table. Determine any of the situations 1) to 4) above.

[0061] Figure 8 shows a database according to another embodiment of the present invention. The management system further includes a database 17 that records the same fixed information 3 and variable information 4 in addition to the game substitute currency 1. The management control device 15 records information in the database 17 based on the reading result of the reading device 13, and can collate the fixed information 3 and variable information 4 stored in the game substitute currency 1 with the information in the database to determine an abnormality.

[0062] In the RFID tag 2 in the embodiment of the present invention, the functionally non-writable area of the non-rewritable area 21 of the data may be the TID. After writing the necessary information in the non-rewritable area 21 of the data, the locked area that cannot be written may be the EPC or the user area. The rewritable area 22 of the data may be the EPC or the user area.

[0063] The reader 13 and the writer 14 may vary in form depending on the location. For example, in the factory 6, it is on the table shown in FIG. 6, in the gate 10, it is box-shaped, and in the bed area 11 and the chip tray 12, the bed area 11 and the chip tray 12 themselves may have the functions of the reader 13 and the writer 14. Also, the gaming tokens 1 may be stacked as they are, or reading and writing may be performed while they are stored in a chip case or the like. Further, the reader 13 and the writer 14 may be integrated.

[0064] In the above embodiment, the case where there is one RFID tag in the gaming token and the single RFID tag has a non-writable area for data and a rewritable area for data has been described. On the other hand, a form in which two RFID tags are inserted into the gaming token, one RFID tag stores fixed information and is locked so that data cannot be written, and the other RFID tag is made rewritable in order to record variable information, is also conceivable.

[0065] However, in this case, when a plurality of gaming tokens are read collectively, as shown in FIG. 7A, since the information group of the fixed information 3 and the information group of the variable information 4 are read separately, the combination of the fixed information and the variable information of a specific gaming token cannot be determined, and there is a problem that a gaming token with an abnormality in the variable information cannot be specified.

[0066] On the other hand, when there is one RFID tag, as shown in FIG. 7B, even when a plurality of gaming tokens are read collectively, the mutual correspondence between the fixed information and the variable information read by the reading device can be grasped. Therefore, it is considered better to implement it with a single RFID tag.

[0067] In general, the larger the diameter of the RFID tag, the higher the reading accuracy. Therefore, when an RFID tag is placed in a gaming token, it is desirable that the RFID tag has a diameter of at least the radius of the gaming token. However, when two RFID tags are placed in a gaming token, the diameter of each individual RFID tag becomes smaller, which is not preferable. Also, when two RFID tags are used, the number of RFID tags to be read increases, which also leads to a decrease in the reading speed when reading a plurality of gaming tokens.

[0068] In view of the above points, it is considered more effective to implement it with a single RFID tag.

[0069] (Third Embodiment) The overall outline of the table game management system in a casino having a plurality of gaming tables according to the embodiment of the present invention will be described below. FIG. 9 is a diagram showing the overall outline of the system. The table game management system in a casino having a plurality of gaming tables 2004 includes a game recording device 2011 that records the games played on the gaming tables 2004 as images via a plurality of cameras 2002 including the gaming tokens 1, an image analysis device 2012 that analyzes the recorded images, a chip reading device 25 that reads the RFID attached to the gaming tokens 1, and a game result determination device 18 that determines and displays the game results of each game on the gaming tables 2004.

[0070] The game result determination device 18 is, for example, a card distribution device 2003, which is a so-called electronic shoe already used by those skilled in the art. The rules of the game are programmed in advance, and it has a structure that can read the information of the distributed cards C and determine the outcome of the game. For example, in the baccarat game, the win of the banker, the win of the player, and a tie are basically determined by the ranks of two or three cards, and the determination result (win / loss result) is displayed on the result display lamp 2013.

[0071] In the figure, the gaming table 2004 is a baccarat table, which is provided with five sitting numbers 13 (sitting number 1 131, sitting number 2 132, sitting number 3 133, sitting number 5 134, sitting number 6 135), and five game participants can participate in the game. A bet area 44 is provided for each sitting number 13. The bet area 44 for the sitting 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 bet by placing the gaming substitute currency 1 in the amount to be bet at the position corresponding to the object of the bet. In FIG. 9, for example, two gaming substitute currencies 1 are placed on the tie 443 of the sitting number 5 and two are placed on the player 441 for betting. The gaming table 2004 is further provided with a player card area 45 for placing the drawn player cards and a banker card area 46 for placing the drawn banker cards.

[0072] The control device 2014 can grasp, via the camera 2002 and the image analysis device 2012, at which position (player, banker, tie, pair) in the betting area 2008 each player 2006 bets the gaming substitute currency 1, the type of the gaming substitute currency 1 (the gaming substitute currency 1 has different value amounts assigned to each color), and the number of sheets. That is, for example, it can be grasped that two are bet on the tie 443 of the sitting number 5 and two are bet on the player 441.

[0073] As shown in FIG. 9, the chip reader 25 is arranged so that the RFID of the gaming substitute currency 1 within the reading area can be collectively read with the entire bet area as one reading area for each seating number. The RFID attached to the gaming substitute currency 1 has unique ID information, the amount, type, manufacturing information, owner information, etc. of the gaming substitute currency 1 written therein. Alternatively, in the database, the ID information may be associated with the amount, type, manufacturing information, owner information, etc. of the gaming substitute currency 1 and stored. By reading the RFID attached to the gaming substitute currency 1, the chip reader 25 can grasp the gaming substitute currency 1 for each seating number and can grasp the total amount or number of sheets. That is, for example, if 4 gaming substitute currencies are bet on seating number 5, the type, amount, and ID of each can be grasped.

[0074] As shown in FIG. 10, based on the image analysis result by the image analysis device 2012, the control device 2014 grasps the total amount or total number of the gaming substitute currency 1 for each seating number from the type and number of the gaming substitute currency 1 bet on each bet area of each seating number, and compares it with the total amount or total number of the gaming substitute currency 1 for each seating number based on the information of the RFID of the gaming substitute currency 1 read by the chip reader 25 to determine whether they match. Further, the seating number with the above determination being inconsistent can be output, and the seating number with a problem can be specified.

[0075] If the total amount or total number of gaming substitute coins 1 for each sitting number based on the reading result of the chip reader 25 is less than the total amount or total number of gaming substitute coins 1 for each sitting number based on the image analysis result by the image analysis device, it is possible that the RFID attached to the gaming substitute coin 1 is broken, is an unreadable RFID, or that the gaming substitute coin 1 is not attached with an RFID. In FIG. 10, for the gaming substitute coins 1 bet on the sitting number 1, the total number of readings based on the image analysis by the image analysis device 2012 is 4, while the total number of readings based on the RFID reading of the chip reader 25 is 3. Therefore, it is considered that out of the 4 gaming substitute coins 1 bet on the sitting number 1, 1 coin had an unreadable RFID.

[0076] If the total amount or total number of gaming substitute coins 1 for each sitting number based on the reading result of the chip reader 25 is more than the total amount or total number of gaming substitute coins 1 for each sitting number based on the image analysis result by the image analysis device, it is possible that the image analysis device 2012 could not read the gaming substitute coin 1 due to factors such as the gaming substitute coin 1 being in the blind spot of the camera. In FIG. 10, for the gaming substitute coins 1 bet on the sitting number 3, the total number of readings based on the image analysis by the image analysis device 2012 is 1, while the total number of readings based on the RFID reading of the chip reader 25 is 2. Therefore, although there were 2 gaming substitute coins 1 bet on the sitting number 3, it is possible that the image analysis device could only recognize 1 coin.

[0077] The ID information of the RFID attached to the gaming substitute coin 1 is registered in the casino's database, and information on production and shipping at the factory, as well as information on receipt, validation, and activation at the casino, is recorded. The control device 2014 can compare the information of the RFID read by the chip reader 25 with the information in the database to determine whether it is genuine or fake as something that should be used in the casino.

[0078] With this configuration, the type and number of the gaming substitute currency 1 wagered in each bed area by the camera can be grasped, and based on the RFID information of the gaming substitute currency 1 read by the chip reader 25, it is possible to determine whether the genuine or fake gaming substitute currency 1 is illegal or defective for each sitting number.

[0079] In addition, the system further includes a face recognition system or a game participant identification means using a player ID card, and the control device 2014 can associate the game participant information identified by the game participant identification means with the sitting number. The control device 2014 can store the bet amount, repayment or recovery amount, and win-loss information stored for each sitting number for each game participant. Also, information on a game participant playing multiple games at multiple tables can be collectively stored.

[0080] The control device 2014 can determine the total amount of the gaming substitute currency 1 in the chip tray 17 of the dealer 2005 of the gaming table 2004 using the chip tray determination device 12. After the game ends and is settled, according to the recovery of the losing gaming substitute currency 1 wagered by each player 2006 and the amount of payment 9W to the winning chips for the winning player 2006W, it is possible to compare and calculate whether the total amount of the gaming substitute currency 1 in the chip tray 17 has increased or decreased according to the win-loss result of the game. The chip tray determination device may grasp the total amount of the gaming substitute currency 1 in the chip tray 17 by photographing the gaming substitute currency 1 accommodated in the chip tray 17 using the camera 2002 and based on the analysis of the image analysis device, or by providing an RFID reader in the chip tray 17, the total amount of the gaming substitute currency 1 accommodated in the chip tray 17 may be detected.

[0081] In this example, fraud or errors are detected based on the game's win / loss result, information on which type of gaming substitute currency 1 was wagered, how many were wagered, and at which position (player, banker, tie, pair) in the wagering area 2008, and the increase or decrease in the gaming substitute currency 1 in the chip tray 17 after the collection of losing chips and the repayment for winning gaming substitute currency 1 are completed. Therefore, even without knowing the movement of the gaming substitute currency 1 after the game ends, that is, whether the wagered gaming substitute currency 1 has moved to the player's side or the dealer's side, fraud or errors can be detected.

[0082] Here, for the game's win / loss result, in the case of baccarat for example, in the card distribution device 2003, by reading the rank of the card C dealt in that game, it can be determined according to the baccarat rules. Also, the game's win / loss result can be determined by photographing the gaming table 2004 with the camera 2002, analyzing the image with the image analysis device 2012, and comparing the analysis result with the game rules by the control device 2014. In this case, the game result determination device is composed of the camera 2002, the image analysis device 2012, and the control device 2014. Information on each player of each sitting number 7, which type of gaming substitute currency 1 was wagered, how many were wagered, and at which position (player, banker, tie, player pair, banker pair) in the wagering area 2008 can be obtained by photographing the gaming substitute currency 1 placed in the wagering area 2008 with the camera 2002 and analyzing the image for each play position 7 with the image analysis device 2012.

[0083] Also, the increase or decrease in the gaming substitute currency 1 in the chip tray 17 before and after the collection of losing gaming substitute currency 1 and the repayment for winning gaming substitute currency 1 are made can be calculated by comparing the total amount of the gaming substitute currency 1 in the chip tray 17 before the collection of losing gaming substitute currency 1 and the repayment for winning gaming substitute currency 1 and the total amount of the gaming substitute currency 1 in the chip tray 17 after the collection of losing gaming substitute currency 1 and the repayment for winning gaming substitute currency 1 are made.

[0084] For example, assume that the total amount of the game substitute currency 1 in the chip tray 17 before the start of the game is Bb, and the total amount of the game substitute currency 1 in the chip tray 17 after the game ends and the collection of losing chips and the repayment for winning chips are completed is Ba. Also, in this game, assume that the total amount of all play positions 7 of the game substitute currency 1 wagered in the player area is bp, the total amount of all play positions 7 of the game substitute currency 1 wagered in the banker area is bb, and the total amount of all play positions 7 of the game substitute currency 1 wagered in the tie area is bt. For example, if the winning or losing result of this game is a win for the banker, then Ba - Bb = bp - bb + bt should hold. Alternatively, the total amount Ba of the game substitute currency 1 in the chip tray 17 after the game ends should be (Bb + bp - bb + bt). If it is not like that, it can be determined that there is fraud or a mistake in the collection or repayment of the chips.

[0085] FIG. 14A is a diagram showing details of the chip tray of the present embodiment, and FIG. 14B is a diagram showing another example of the chip tray. The chip tray 17 is provided with a collection chip tray 171 for collecting and temporarily storing the game substitute currency 1L wagered by the losing player 2006L and a repayment chip tray 172 for storing the game substitute currency 1W to be repaid. The image analysis device 2012 and the control device 2014 grasp the position, type, and number of the game substitute currency 1L wagered by the losing player 2006L, and calculate the increased amount of the game substitute currency 1L in the game (the amount of the game substitute currency 1 that should be in the collection chip tray 171). Further, the image analysis device 2012 and the control device 2014 grasp the actual total amount of the game substitute currency 1 in the chip tray 171 after collection, and compare the should-be total amount with the actual total amount to determine whether there is a difference.

[0086] The control device 2014 further repays the gaming substitute currency 1 to be repaid, and when the repayment is completed, based on the position, type, and number of chips wagered by each game participant on the gaming table and the game result, it calculates the total amount that should be in the chip tray for the chips to be repaid in the game, and compares it with the actual total amount in the chip tray, and can determine whether there is a difference between the total amount that should be and the actual total amount.

[0087] Also, for the repayment of the gaming substitute currency 1W to the winning player 2006W, by using the gaming substitute currency 1 in the repayment chip tray 172, sufficient time can be ensured to grasp the actual total amount of the gaming substitute currency 1 in the collection chip tray 171 after the image analysis device 2012 and the control device 2014 have collected it.

[0088] As described above, in this embodiment, the control device 2014 calculates the chip balance for each game based on the amount of wagered chips on the gaming table 2004 and the win / loss result of the game, and verifies the increase in the remaining amount of chips in the chip tray 17 after the game. If a difference is detected in this verification, the control device 2014 issues an alarm or adds a record to that effect to the recording of the video captured by the camera 2002. The casino operator can investigate the cause of the difference by checking the video.

[0089] The table game management system of this embodiment adds and subtracts the increase or decrease amount of chips in the game calculated from the total amount of the gaming substitute currency 1 in the chip tray 17 before the settlement of each game, the position, type, and number of the gaming substitute currency 1 wagered by all players 2006 in the game, and the win / loss result of the game obtained by the win / loss result determination device, and compares the total amount that should be in the chip tray 17 after the settlement at the end of the game with the actual total amount of the gaming substitute currency 1 in the chip tray 17 at the end of the game obtained through the image analysis device 2012, and determines whether there is a difference between the total amount that should be and the actual total amount.

[0090] The control device 2014 grasps the position, type, and number of chips wagered by each player via the image analysis device 2012. When all the losing chips wagered by each player have been collected, it grasps the actual total amount of chips in the chip tray. From the total amount of chips in the chip tray before the settlement of each game, it adds the increase in the chip tray 17 in the game based on the position, type, and number of chips wagered by the losing player, and then compares the supposed total amount of the gaming substitute currency 1 in the chip tray 17 with the actual total amount of the gaming substitute currency 1 in the chip tray 17 to determine whether there is a difference between the supposed total amount and the actual total amount.

[0091] The control device 2014 compares the supposed total amount of the gaming substitute currency 1 in the chip tray 17, which is obtained by adding the increase in the chip tray 17 in the game based on the position, type, and number of the gaming substitute currency 1 wagered by the losing player to the total amount of the gaming substitute currency 1 in the chip tray 17 before the settlement of each game, with the actual total amount of the gaming substitute currency 1 in the chip tray 17. If it determines that there is no difference between the supposed total amount and the actual total amount, and when comparing the supposed total amount in the chip tray 17 after the settlement at the end of the game with the actual total amount of the gaming substitute currency 1 in the chip tray 17 at the end of the game obtained via the image analysis device 2012, if it determines that there is a difference between the supposed total amount and the actual total amount, it determines that there is an error in payment and generates a payment error signal to notify the error in payment.

[0092] The chip tray 17 is provided with a recovery chip tray 171 for collecting and temporarily storing the gaming substitute currency 1 wagered by the losing player. The image analysis device 2012 compares the supposed total amount of the gaming substitute currency 1 in the recovery chip tray 171, which is calculated by adding the increase in the gaming substitute currency 1 in the game based on the position, type, and number of the gaming substitute currency 1L wagered by the losing player, with the actual total amount of the gaming substitute currency 1 in the recovery chip tray 171 to determine whether there is a difference between the supposed total amount and the actual total amount.

[0093] When the control device 2014 determines a difference that the actual total amount of the gaming tokens 1 grasped in the chip tray 17 of the dealer 2005 on the gaming table 2004 does not correspond to the increase or decrease amount of the chips calculated from the chip amounts wagered by all players and the win / loss result of the game, the game recording device 2011 indexes or times the acquired video, or identifies and reproduces the collection scene or payment scene of the gaming tokens 1 so that the recording of the game in which the above difference occurred can be analyzed in the game recording device 2011.

[0094] In this way, the control device 2014 obtains the total amount of chips in the chip tray 17 after the settlement at the end of the game via the image analysis device 2012. In this case, the post-settlement judgment is assumed to occur when any of the following 1) to 4) occurs. 1) When the repayment for the winning gaming tokens 1 is completed, 2) When the card C used in the game is collected and discarded in the discard area 41 or the discard slot 42 of the table, 3) When a predetermined button attached to the win / loss result determination device is pressed, 4) When the marker 43 indicating the win / loss is reset.

[0095] In addition, the control device 2014 grasps the position (the position wagered on the player, the banker, or the pair) and the amount (type and number) of the chips wagered at each play position 7 on the gaming table 2004, and compares the win / loss history of each player 2006 obtained from the win / loss result of each game and the amount of the chips obtained (the winning amount) with the statistical data of a large number (big data) of past games to extract as a special situation (set by the casino) an artificial intelligence utilization type or a deep learning structure. Typically, the occurrence of a winning amount of a certain amount (one million dollars) or more, or at a play position 7 on a certain gaming table 2004, a state where the amount of the wagered chips when losing is small and the amount of the wagered chips when winning is large continues for several games, and this can be extracted as a special situation compared with the statistical data (big data, etc.) of past games. It is equipped with a control device 2014 having an artificial intelligence utilization type or a deep learning structure.

[0096] Furthermore, the control device 2014 of the management system of this table game is structured such that (integrated with the image analysis device 2012) it can identify a specific situation or an individual player 2006 at a play position 7 where a certain amount or more of wins have been achieved. Such identification of the player 2006 is obtained in the image analysis device 2012 by extracting feature points from a face image and attaching an identity number (ID, etc.) for identification. Then, when the identified player 2006 leaves and arrives at another gaming table, the control device 2014 has a warning function to notify the presence of the specific player at the other gaming table. Specifically, it notifies the pit manager who manages each gaming table 2004 and each table responsible person (which may be a dealer) to prevent further specific phenomena.

[0097] The control device 2014 can identify the recovered gaming substitute currency 1 for each sitting number based on the RFID ID information of the recovered gaming substitute currency 1 determined by the chip tray determination device and the RFID ID information of the gaming substitute currency 1 read by the chip reader 25.

[0098] In FIG. 11, gaming substitute currency 1 is being wagered as shown in the detailed tables of FIGS. 12 and 13. In the analysis by the image analysis device 2012, the location (player, banker, etc.) and the number of pieces (and amount) where the gaming substitute currency 1 is being wagered can be grasped. On the other hand, in the reading by the chip reader 25, the RFID ID attached to the gaming substitute currency 1 for each sitting number can be grasped. Furthermore, since the chip tray determination device 25 can determine the ID of the gaming substitute currency 1 in the chip tray 9, by grasping the ID that has increased before and after recovery, the recovered gaming substitute currency 1 can be grasped. In FIGS. 11 to 13, when the game result is a win for the banker, it can be seen from the analysis result of the image analysis device 2012 that 2 pieces wagered on the banker pair should be recovered, and among the IDs of the recovered chips determined by the chip tray determination device, it can be seen that 2 pieces with IDs 6 and 18, which the chip reader 25 has read as being wagered at sitting number 5, have been recovered.

[0099] The control device 2014 further determines the total amount or total number of the gaming substitute coins 1 to be recovered for each sitting number by using the gaming result obtained from the game result determination device and the measurement results of the position, amount, and number of the gaming substitute coins 1 based on the image analysis result by the image analysis device. Therefore, the control device 2014 can compare the total amount or total number of the recovered gaming substitute coins 1 for each sitting number determined based on RFID with the total amount or total number of the gaming substitute coins 1 to be recovered based on the image analysis result, and determine whether they match.

[0100] For example, when the reading result by the chip reading device 25 for sitting number 1 is "A, B, C, D, E", the analysis result by the image analysis device 2012 is "2 for Tie and 2 for Banker", the game result is "Banker wins", and the reading result by the chip tray determination device 18 is "A, B", it can be seen that the chips A and B bet on Tie are correctly recovered.

[0101] The control device 2014 can further determine whether the RFID ID information of the recovered gaming substitute coins 1 determined by the chip tray determination device matches the RFID ID information of the bet gaming substitute coins 1 read by the chip reading device 25. By this determination, it can be determined whether the gaming substitute coins 1 recovered in the chip tray are the gaming substitute coins 1 bet on the gaming table, and whether they are not gaming substitute coins 1 recovered illegally from other places.

[0102] The control device 2014 can further determine the types of chips such as cash chips, rolling chips, and promotion chips based on the RFID information read by the chip reading device 25, and can store the bet amount, recovered or repaid amount for each determined chip type.

[0103] A rolling chip is a special chip that can be purchased by specific members and cannot be exchanged for cash. The amount of money spent on purchasing rolling chips is managed for each member. It must be used for betting and consumed. Also, the repayment for bets made using rolling chips is made with cash chips. By storing the amount of rolling chips bet or collected based on the RFID information read by the chip reader 25, it is possible to grasp the amount of rolling chips that a specific member should have.

[0104] The chip reader 25 is further equipped with the function of a confirmation area and can read the gaming substitute currency 1 placed for repayment. As shown in FIG. 15, when repaying the banker of the sitting number 2, the gaming substitute currency 1 for repayment is placed in the chip reader 25 and read. In FIG. 15, it is placed beside the winning gaming substitute currency 1 bet on the banker of the sitting number 2. The control device 2014 uses the game result obtained from the game result determination device and the measurement results of the position, amount, and number of the gaming substitute currency 1 based on the image analysis result by the image analysis device to determine the repayment amount, and compares it with the amount of the gaming substitute currency 1 placed for each sitting number based on the reading result of the chip reader 25, determines whether the repayment amounts match or not, and can output the result. In FIG. 16, the total number of gaming substitute currency 1 to be paid for the sitting number 1 is 4, while the reading result of the chip reader 25 is 3, so they do not match. When the repayment amounts do not match, a non-matching signal is output, and the dealer can re-place the gaming substitute currency 1 for repayment based on the output signal. When the gaming substitute currency 1 is re-placed, the determination is made again, and the determination result can be output. The area where the gaming substitute currency 1 for repayment is placed can be anywhere within the chip reader 25. Also, as shown in FIG. 15, separately from the bet area, a payment confirmation area 26 may be arranged on the dealer side of the bet area. In FIG. 7, the gaming substitute currency 1 for repayment is placed in the payment confirmation area 26 of the sitting number 6, the chip reader 25 reads it, the control device 2014 makes a determination, and a repayment chip is placed beside the winning gaming substitute currency 1 placed on the banker.

[0105] Also, image analysis of the confirmation area may be performed by the image analysis device 2012, and the control device 2014 may collate it with the reading result of the chip reader 25 to determine whether the total number of pieces matches.

[0106] Based on the determination made, the control device 2014 can output a signal. The signal may be output so as to be displayed on the display unit of the chip tray 9 or the display unit of the card dispenser 13, or the signal may be output to the pit manager or the casino backyard.

[0107] As shown in FIG. 17, the chip reader 25 may use the entire bet area as one reading area for each sitting number. As shown in FIG. 18, for each sitting number, the player bet area and the banker bet area may be regarded as one reading area, and the tie bet area, the player pair bet area, and the banker pair bet area may be regarded as one reading area. Also, as shown in FIGS. 19 and 22, each of the side bet areas of the tie bet area, the player pair bet area, and the banker pair bet area may be regarded as one reading area.

[0108] Hereinafter, the substitute gaming currency 1 used in the embodiment of the present invention will be described. FIG. 20 is an external view of the substitute gaming currency 1 used in this system, and FIG. 21 is a front cross-sectional view. A plurality of plastic layers of different colors are laminated, and at least a colored layer 101 is provided in the middle. A white layer 102 or a light-colored layer (not shown, as long as it is a layer lighter in color than the colored layer 101) is laminated on both sides of the middle colored layer 101, forming a multilayer structure. By having such a colored layer 101 and laminating a white layer 102 or a light-colored layer (not shown, as long as it is a layer lighter in color than the colored layer 101) on both sides of the middle colored layer 101, a stripe pattern in the lamination direction is formed on the side surface as shown in FIG. 20. By changing the color of the colored layer 101 (such as red, green, yellow, or blue), the types of the substitute gaming currency 1 (such as 10 points, 20 points, 100 points, 1000 points, etc.) can be specified.

[0109] As shown in FIG. 21, the coloring layer 101 may be formed by a plurality of colored layers (three layers in FIG. 21). Since the plurality of colored layers (three layers in FIG. 21) are thermocompression bonded to each other, the three-layer structure is not visible as shown in FIG. 21, and FIG. 21 represents three layers for explanatory purposes. Further, a partial cutout B is provided in the middle layer of the three layers of the coloring layer 101, and an RFID is built therein.

[0110] Also, the gaming substitute currency 1 is not limited to a structure in which plastics are laminated, and may have an appearance similar to that of the coloring layer 101.

[0111] The method by which the image analysis device 2012 analyzes the gaming substitute currency 1 is shown in detail below. The image analysis device 2012 analyzes the image recorded in the recording device 11, and recognizes at least two colors of a reference color R different from the specific color 121 that is at least partially applied to the gaming substitute currency 1 and present in the image. The specific color 121 is at least partially applied at a predetermined position or in a predetermined shape of the gaming substitute currency 1. For example, it may be applied as the coloring layer 101, applied circumferentially on the side surface of the gaming substitute currency 1, or applied as a predetermined mark on the surface of the gaming substitute currency 1. Also, the reference color R may be, for example, the color of a specific area of the gaming table 2004, or a color applied at a location different from the specific color 121 in the gaming substitute currency 1.

[0112] The image analysis device 2012 includes, for example, an artificial intelligence device 12a that identifies a specific color by deep learning technology or the like, and determines the number and types of the gaming substitute currency 1 arranged on the gaming table 2004. The recognition device 12 may further determine the position of the gaming substitute currency 1 on the gaming table 2004.

[0113] The image analysis device 2012 acquires a plurality of images of the gaming substitute currency 1 and the reference color R irradiated with different illuminances, and learns by a person teaching the acquired images and the correct colors of the specific color 121 of the gaming substitute currency 1 and the reference color R in each image as teaching data, and creates a learning model 13a (recognition program). Note that for the images of the gaming substitute currency 1 and the reference color R irradiated with the same illuminance condition, since the specific color 121 and the reference color R are irradiated with the same illuminance, the relative relationship between the specific color 121 and the reference color R can be acquired. For example, this relative relationship may be used for the recognition of the specific color 121.

[0114] In addition, the chip recognition device 12 may extract the center line C of the gaming substitute currency 1 by a method of measuring features on the image such as shape, brightness, saturation, and color tone, using the result of image analysis recorded as an image taken by the camera 200212 without using artificial intelligence.

[0115] The artificial intelligence device 12a further analyzes a peripheral image in a predetermined range around the extracted center line C (for example, a range of 8 pixels orthogonal to the center line centered on the center line), and recognizes at least two colors including the specific color 121 and the reference color R different from the specific color 121 in the peripheral image. When analyzing the peripheral image in a predetermined range around the extracted center line C, the image may be analyzed as it is, or may be analyzed after performing image processing such as color enhancement and noise removal so that the recognition of the specific color 121 becomes easy.

[0116] In summary, the artificial intelligence device 12a of the recognition device 12 has a configuration of extracting the center line C from the image of the gaming substitute currency 1 and analyzing the peripheral image in a predetermined range centered on the center line C to recognize at least two colors including the specific color 121 and the reference color R different from the specific color 121 in the peripheral image, and is an artificial intelligence device taught with a plurality of the peripheral images of the gaming substitute currency 1 and the reference color R irradiated with different illuminances as teaching data.

These technologies are technologies for performing image recognition on a captured image to recognize an object included in the image. In particular, in recent years, object recognition with high accuracy has been performed using deep learning technology in which neural networks are multi-layered. This deep learning technology generally recognizes an object with high accuracy by stacking layers in multiple stages in an intermediate layer between the input layer and the output layer of a neural network. In this deep learning technology, in particular, the convolutional neural network has attracted attention for having higher performance than recognizing an object based on conventional image feature amounts.

[0121] In a convolutional neural network, a recognition target image with a label is learned, and the main object included in the recognition target image is recognized. When there are a plurality of main objects in the learning image, a region rectangle is specified, and a label is assigned to the image corresponding to the specified region for learning. Further, in a convolutional neural network, it is also possible to determine the main object in the image and the position of the object.

[0122] To further explain the convolutional neural network, in the object recognition process, candidate regions are extracted based on local features by performing edge extraction processing or the like on the image of the object to be recognized. Then, the candidate regions are input into the convolutional neural network to extract feature vectors, and classification is performed. The candidate region with the highest confidence level after classification is obtained as the recognition result. The confidence level indicates the degree to which the similarity of the main body of the image learned together with a certain image region and a label is relatively higher than the similarity of other classes.
