[0104] (First Embodiment)

[0105] Use Figure 1 To explain the overall overview of the tabletop game management system of the first embodiment of the present invention. Figure 1 This is a diagram showing the overall overview of the system. The amusement table 1004 for card games has placement areas for P1441, B 1442, draw 1443, P.P1444, and B.P1445 set according to each player position 1131 to 1135. In addition, a game coin placement area 1025 is provided at each player position, and a game coin reading device 1002 for reading the RFID of the game coins 1001 placed in this game coin placement area is provided.

[0106] Further, a PAIR area 1026 is provided in each game coin configuration area 1025. The PAIR area 1026 is used to place the game coins 1001 taken out from the game coin tray 1009 when the dealer pays the winner with the game coins 1001 from the game coin tray 1009 of the gaming table 1004.

[0107] In addition, a control device 1003 is provided, which grasps the RFID reading result of the game coin 1001 read by the game coin reading device 1002.

[0108] At the start, the players participating in the game place the game coins 1001 in the placement area within the game coin configuration area. The RFID of the placed game coins 1001 is read by the game coin reading device 1002, so that the control device 1003 grasps the information about the owner of the game coin 1001 associated with the ID information of the RFID in the database.

[0109] Based on the result of the game, if the casino side wins, the dealer retrieves the game coins 1001 placed by the losers 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 through the control device 1003, the information that the owner of the game coin 1001 retrieved by the casino side is the casino is recorded in the database.

[0110] Based on the result of the game, for the winner, the dealer pays the winner with the game coins 1001 in an amount corresponding to the amount of the placed game coins according to the rules of the game from the game coin tray.

[0111] At the time of payment, the payment game coins can be placed in the above-mentioned PAIR area 1026, or can be placed in the game coin configuration area outside the PAIR area.

[0112] Here, Figure 2 A description is given of the method for recording the owner information of the payment game coins. Figure 2 It is a method for recording the information related to the owner of the game coin 1001 when paying the winner with the game coins.

[0113] When multiple players place game coins within the same player position and there are two or more stacks, the game coin reading device 1002 reads all the game coins 1001 placed within the game coin configuration area 1025. Therefore, during 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 win / loss result of the game is determined and payment is made to the winner, the dealer makes payment to each player (each stack) from the game coin tray 1009. The game coins 1001 taken out from the game coin tray 1009 are placed within the game coin configuration area 1025. The game coin reading device 1002 reads the ID 1011 of the payment game coins placed within the game coin configuration area 1025.

[0114] The payment game coins 1001 and the initially placed game coins 1001 are received together by the winner. At this time, the placed game coins and the payment game coins move outside the game coin configuration area 1025. Therefore, the IDs of the placed game coins and the payment game coins disappear from the reading result obtained by the game coin reading device 1002. Thus, the control device 1003 associates with the information related to the owner of the placed game coins to determine which player the paid payment game coins are paid to.

[0115] The control device 1003 associates and stores the information related to the owner of the payment game coins that it has determined and the ID of the game coins in the database.

[0116] Based on the above, the traceability of the owner of the game coins 1001 becomes possible. When there is improper receipt of the game coins 1001, etc., it is possible to discover the situation where the owner information stored in the database is different from the actual owner.

[0117] In addition, in terms of determining the actual owner, it can be achieved by using face recognition technology and IDs such as membership cards.

[0118] Furthermore, in the above description, although the IDs of each game coin are managed in the database, it is also possible to have a structure in which the owner information is stored in the game coin 1001 itself.

[0119] In addition, the above PAIR area 1026 is configured such that, in addition to being set according to each player position, it can also be configured as an area independent of each player position, and the reading of the game coin reading device 1002 is performed independently.

[0120] Furthermore, it can also be configured such that, depending on the reading performance of the game coin reading device 1002, it is possible to select between the case of using the PAIR area 1026 and the case of not using it.

[0121] Furthermore, the present tabletop game management system can also be configured to mutually utilize information in combination with an RFID reader that reads game coins in the game coin tray 1009, a camera that reads the placed game coins, a shoe for determining the winning or losing result of the game, and other winning or losing result determination devices.

[0122] (Second Embodiment)

[0123] First, the game coins used in the game coin management system according to the embodiment of the present invention will be described. Figure 3 Reference numeral 1 denotes a game coin used in the same system. In the same figure, an RFID tag 2 capable of storing various information is embedded in the game coin 1. The RFID tag 2 has a region 21 where data cannot be rewritten and a region 22 where data can be rewritten.

[0124] The region 21 where data cannot be rewritten stores fixed information 3 with information that does not change during the use of the game coin 1, or information that cannot be changed, or information that must not be changed. 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 date of manufacturing the game coin, the manufacturing machine, etc., and the product information includes, for example, information indicating a game coin for the VIP area of the casino, information indicating the type of game coin (e.g., information indicating transcoding), etc.

[0125] In terms of the form of the RFID tag, the region 21 where data cannot be rewritten can be a functionally non-writable area or a locked area so that after necessary information is written in the writable area, data cannot be written anymore.

[0126] The region 22 where data can be rewritten stores variable information 4 with information that changes during the use of the game coin 1. For example, as Figure 3 shown, location-related information 220 including information 221 related to date and time, information 222 related to location and event, information 223 related to the owner, etc. is stored as variable information 4.

[0127] To prevent others from improperly reading and writing information, the fixed information 3 and variable information 4 can be encrypted. In addition, the fixed information 3 and variable information 4 can be stored as metadata.

[0128] Figure 4 An example of the recording method of the data of the variable information 4 of the game coin 1 is shown. As Figure 4As shown, it is configured to take the location-related information 220 composed of date, time information 221, location, event information 222, and owner information 223 as a block, link the information of this block in a chain, and further be able to grasp the history of the location-related information 220 of the game coin 1.

[0129] In Figure 4 An example of the change information 4 stored in the game coin 1 is shown, and the movement of the game coin 1 as shown below can be grasped. Mr. A purchased the game coin 1 at the counter 5 at 16:02 on January 28, 2019. Mr. A placed the game coin 1 at Table No. 325 at 16:15 on the same day. Mr. B received the game coin 1 at Table No. 325 at 16:43 on the same day as the repayment for the placement win. Mr. B left the casino with the game coin 1 at 17:01 on the same day.

[0130] The change information 4 can be configured to store only the latest information, or can store all the location-related information written. In addition, as Figure 4 shown, several can be selected and stored from among the multiple location-related information. In the case of selecting several for storage, multiple location-related information including at least the latest location-related information 220 among all the location-related information 220 can be stored. According to the above structure, based on the change information 4 of a certain game coin 1, the history of the use or movement of the game coin 1 can be understood. That is, the traceable information of the game coin 1 is configured to be written into the game coin 1 itself and can be grasped.

[0131] Next, the management system of the game coin 1 of the present embodiment will be described. Figure 5 It shows the overall outline of the same system.

[0132] First, in the factory 6, the game coin 1 writes the change information 4 including the information of manufacturing completion or factory shipment as the location-related information 220 into the rewritable area 22 of the RFID tag 2 through the writing device 14.

[0133] At the backstage 7 of the casino, reception processing is performed on the game coins 1 shipped from the factory 6. In the backstage 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 location-related information 220 written in the factory 6, which is the information to be written, is written as the latest change information 4. Assuming that if there is no writing record in the factory 6, the game coin is regarded as a game coin with suspicion of irregularity, and an error signal is generated. Thus, the casino side can refuse to receive the game coin or commission the factory side to conduct an investigation. If the writing record is okay, through the writing device 14, the location-related information 220 of the backstage is written into the rewritable data area 22 of the RFID tag 2. When writing, the location information of the backstage can be added to the location information of the factory, or the location information of the factory can be deleted and the location information of the backstage can be recorded. In addition, the above reading and writing of game coins in the backstage 7 can be carried out together with the normal verification and activation operations of the game coins.

[0134] The game coins 1 that have completed the reception inspection in the backstage 7 are transported to the warehouse 8 or the counter 9 of the casino. At the warehouse 8 or the 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, which is the information to be written, is written as the latest change information 4. In addition, it can be checked whether the information indicating the factory 6 is written into the history record of the change information 4. Similar to the above inspection in the backstage 7, the management control device 15 determines whether there is an abnormality in the history record of the location information. If the reading result is okay, the writing device 14 writes the location-related information of the warehouse 8 or the counter 9 into the rewritable data area 22.

[0135] The player purchases the game coin 1 at the counter 9. When the player purchases the game coin 1, through the writing device 14 located at the counter 9, the information indicating the time of purchase of the game coin and the change of the owner of the game coin from the casino to the guest is written as the change information 4. It can also be configured to identify and record the player through face recognition technology, the casino membership card, the ID card such as the ID card.

[0136] Players play the game by placing the purchased game coins 1 on the gaming table in the placement area 11. The reading device 13 reads the location-related information 220 composed of the date, time information 221, location, event information 222, and owner information 223 from the RFID tag 2 of the placed game coin 1, and the management control device 15 determines whether there is no abnormality. For example, it can be determined as abnormal in the following cases: when a certain period of time has passed since the date of the last written usage information on the gaming table and the purchased information at the counter, and when the owner information 223 stored in the game coin 1 is different from the owner information 223 determined by face authentication or ID card.

[0137] In the case where the reading result is okay, for the placed game coin 1, the writing device 14 adds the location-related information 220 to the area 22 where the data can be rewritten. The location-related information 220 includes the date, time information 221, location, event information 222, and owner information 223. At the gaming table, for example, the writing device 14 writes the change information 4 including the player position number where the game coin 1 is placed and the player's information. The player's information can be determined by ID card or face authentication. Usually, since several game coins 1 are placed overlappingly in the placement area 11, writing is performed together in the overlapping state.

[0138] When the player takes out the game coin 1 from the casino side, the exit process is carried out at the entrance / exit 10. At the time of exit, the reading device 13 reads the location-related information 220, and the management control device 15 determines whether the change information 4 is abnormal. In addition, at the entrance / exit 10, the writing device 14 writes the change information 4 including the location indicating the exit, event information 222, and owner information 223.

[0139] When the player enters from the casino side and brings in the game coins taken out previously, the reading device 13 reads the location-related information, and the management control device 15 determines whether the change information 4 is abnormal. For example, for the game coin 1 temporarily taken out from the casino, in the case where the owner at the time of exiting the casino is different from the owner at the time of entering, the receipt behavior of the game coin outside the casino can be grasped.

[0140] When the determination based on the reading result of the reading device 13 is abnormal, the management control device 15 can output an alarm to the counter 9 or the entrance / exit 10. When the owner of the game coin 1 exits from the entrance / exit 10, individual inspection can be performed at the time of exit based on the alarm output by the management control device 15. In addition, when the determination result is abnormal, the management control device 15 issues a warning to interrupt the game to the dealer at each gaming table, or issues a warning to the gaming table. The gaming table manager can judge whether to interrupt the game or continue the game, etc., or perform processing such as replacing the game coin 1. Alternatively, the management control device 15 is configured to be connected to the overall management control device 18 of the casino and issue a warning to the overall management control device 18.

[0141] In addition, in the above description, although the method of reading by the reading device 13, determining by the management control device, and then writing by the writing device 14 has been described, it can also be a structure that performs reading and writing simultaneously.

[0142] Hereinafter, the detailed situation of the application embodiment of the present invention will be described.

[0143] In the factory 6, when production is completed and when shipping, reading and / or writing of the RFID tag 2 is performed. The writing device 14 writes the production information and the product information as the fixed information 3, and locks it in a non-rewritable manner as needed, and writes the variable information 4.

[0144] In the backstage 6, when receiving the game coin 1 shipped from the factory and activating it to be a usable game coin 1, reading and / or writing of the RFID tag 2 is performed.

[0145] In the warehouse 8, when moving the game coin 1 from the warehouse 8 to the counter 9 or moving the game coin 1 from the counter 9 to the warehouse 8, reading and / or writing of the RFID tag 2 is performed. Alternatively, for the game coin 1 stored in the warehouse 8, reading and / or writing of the RFID tag 2 can be performed at regular intervals or at a specified time.

[0146] At the counter 9, when moving from or to the warehouse 8, reading and / or writing of the RFID tag 2 is performed. The owner information 223 can be obtained based on the player's casino ID card, face recognition system, credit card, etc.

[0147] When a player enters and exits through the entrance / exit 10, the RFID tag 2 is read and / or written. For all the game coins 1 that a player takes out of the casino when exiting, the information indicating the place of removal, the event information 222, and the owner information 223 of the player who takes them out are written as the change information 4 and registered. Similarly, when entering, the information indicating the place of entry, the event information 222, and the owner information 223 of the player who brings them in are written as the change information 4 and the game coins 1 brought into the casino are registered.

[0148] In the placement area 11, for the game coins 1 that a player places in the placement area 11 to participate in the game, the RFID tag 2 is read and / or written. In addition, for the game coins 1 that a dealer places in the placement area 11 as a repayment to the player, the RFID tag 2 is read and / or written.

[0149] In the game coin tray 12, for the game coins 1 recycled into the game coin tray and the game coins 1 stored in the game coin tray, the RFID tag 2 is read and / or written.

[0150] The gaming table also has a payment area where the RFID tag 2 can be read and / or written for the game coins 1 that a dealer places in the placement area 11 as a repayment to the player.

[0151] The management control device 15 has the following functions: determining whether there is an abnormality in the location-related information 220 obtained from the reading results of the reading devices 13 at each location. As the determination of whether there is an abnormality, it is possible to determine whether any of the following situations exist: not used for a specified time or more after the last write, or the location-related information that should be written is not written.

[0152] The situation of not being used for a specified time or more after the last write is any of the following situations.

[0153] 1) The latest location-related information indicates the information of the counter 9, and the next information write takes more than the specified time;

[0154] 2) The latest location-related information indicates the information of entering through the entrance / exit 10, and the next information write takes more than the specified time;

[0155] 3) The latest location-related information indicates the information of exiting through the entrance / exit 10, and the next information write takes more than the specified time.

[0156] The situation where the location-related information that should be written is not written is any of the following situations:

[0157] 4) When entering the amusement arcade, the latest location-related information in the rewritable area 22 of the game token 1 does not record the information indicating exit at the entrance / exit 10.

[0158] 5) When used at the counter 9, the information indicating the backstage 7 is not recorded.

[0159] 6) When exiting the amusement arcade, the information indicating the counter 9 or the backstage 7 is not recorded.

[0160] The management control device 15 can determine any of the following situations based on the owner-related information 223 obtained by the reading device 13, as a determination of whether it is abnormal.

[0161] 1) A person different from the final owner stored in the rewritable area 22 exchanges the game token 1 in the amusement arcade or exits the amusement arcade.

[0162] 2) A person different from the owner at the time of exit stored in the rewritable area 22 brings the game token into the amusement arcade.

[0163] The management control device 15 determines any of the following 1) to 4) based on the information indicating the location of the placement area 11, or the information indicating the location of the game token tray 12, or the information indicating the payment area obtained by the reading device 13, as a determination of whether it is abnormal:

[0164] 1) A person different from the final owner stored in the rewritable area 22 uses the game token 1 at the game table.

[0165] 2) Using a game token 1 in the amusement arcade that does not have the information indicating the counter 9 or the backstage 7.

[0166] 3) When the latest location-related information is the information indicating the placement area 11 or the payment area, and after a specified time has passed, it is used at the game table.

[0167] Figure 8 The database related to other embodiments of the present invention is shown. The management system further includes a database 17 that records the same fixed information 3 and variable information 4 in addition to the game token 1. The management control device 15 can record 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 token 1 with the information in the database to determine abnormality.

[0168] In the RFID tag 2 of the present embodiment, the non-rewritable area of the area 21 where data cannot be rewritten can be the TID (tag number). After writing the necessary information in the area 21 where data cannot be rewritten, the locked area where data cannot be rewritten can be the EPC or the user area. The area 22 where data can be rewritten can be the EPC (electronic product code) or the user area.

[0169] The reading device 13 and the writing device 14 can change their forms according to the location. For example, in the factory 6, it can be Figure 6 the device on the table shown. The entrance 10 is box-shaped. In the placement area 11 and the game coin tray 12, the placement area 11 and the game coin tray 12 themselves can have the functions of the reading device 13 and the writing device 14. In addition, the game coins 1 can be read in a directly stacked state or in a state of being stored in a game coin box or the like. In addition, the reading device 13 and the writing device 14 can be integrally formed.

[0170] In the above embodiment, the case where a game coin has one RFID tag and this single RFID tag has a non-rewritable area and a rewritable area has been described. In this regard, the following form can also be considered: Two RFID tags are placed in the game coin. One of the RFID tags stores fixed information and is locked so that data cannot be rewritten, while the other RFID tag records variable information and is therefore preset to be able to rewrite data.

[0171] However, in this case, the following problem will occur: When reading multiple game coins together, as Figure 7A shown, since the information group of the fixed information 3 and the information group of the variable information 4 can be read separately, it is impossible to determine the combination of the fixed information and the variable information of a specific game coin, and it is impossible to identify the game coin with abnormal variable information.

[0172] In contrast, in the case of one RFID tag, as Figure 7B shown, even when reading multiple game coins together, the mutual correspondence relationship 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.

[0173] In addition, generally speaking, the larger the diameter of the RFID tag, the higher the reading accuracy. Therefore, when placing the RFID tag in the game coin, it is desirable that the RFID tag has a diameter of at least more than the radius of the game coin. However, since two RFID tags are placed in the game coin, the diameter of each RFID tag becomes smaller, so it is not preferred. In addition, if two RFID tags are placed, the number of RFID tags to be read increases, so when reading multiple game coins, the reading speed decreases.

[0174] Through the above aspects, it can be considered that it is more effective to implement with a single RFID tag.

[0175] (Third Embodiment)

[0176] The following clarifies the overall outline of the management system for table games in a game hall with multiple gaming tables according to the embodiments of the present invention. Figure 9 As a diagram showing the overall outline of the same system, the management system for table games in a game hall with multiple gaming tables 2004 includes: a game recording device 2011 that records the games played on the gaming table 2004, including game coins 1, as images via multiple cameras 2002; an image analysis device 2012 that performs image analysis on the recorded images; a game coin reading device 25 that reads the RFID attached to the game coin 1; and a game result determination device 18 that determines and indicates the game results of each game on the gaming table 2004.

[0177] The game result determination device 18 is, for example, a card dealing device 2003, a so-called electronic dealing shoe that has been used by those skilled in the art. Its structure is such that the game rules are programmed in advance, the information of the dealt cards C is read, and the winning or losing of the game can be determined. For example, in a certain card game, the win of Player B, the win of Player P, and a draw (tie) are basically determined by the face values of 2 - 3 cards, and the determination result (winning or losing result) is indicated by a result display lamp 2013.

[0178] In the same figure, the gaming table 2004 is a table for a certain card game, and five seat numbers 13 ("Seat Number 1" 131, "Seat Number 2" 132, "Seat Number 3" 133, "Seat Number 5" 134, "Seat Number 6" 135) are set, and 5 game participants can participate in the game. A placement area 44 is set for each seat number 13. The placement area 44 corresponding to the seat number 13 includes areas for P (PLAYER) 441, B (BANKER) 442, Tie 443, P.P 444, and B.P 445. Each game participant plays the game by placing the placed amount of game coins 1 at the position corresponding to the placed object. In Figure 9 For example, 2 game coins 1 are placed in the Tie 443 of Seat Number 5, and 2 game coins 1 are placed in the P 441 of Seat Number 5 to play the game. In the gaming table 2004, a Player P card area 45 for placing the drawn Player P cards and a Player B card area 46 for placing the drawn Player B cards are also set.

[0179] The control device 2014 can, by means of the camera 2002 and the image analysis device 2012, grasp at which positions (P, B, draw, PAIR) each player 2006 places the game coins 1 in the placement area 2008, the types (the game coins 1 are divided into different value amounts according to each color) and the number of the placed game coins 1. That is, for example, the control device 2014 can grasp that 2 game coins 1 are placed in the draw 443 of seat number 5 and 2 game coins 1 are placed in P441.

[0180] As Figure 9 shown, the game coin reading device 25 is configured to be able to read the RFID of the game coins 1 in the reading area together by taking the entire placement area as one reading area according to each seat number. The RFID attached to the game coin 1 writes in inherent ID information, the amount, type, manufacturing information, owner information, etc. of the game coin 1. Or, in the database, the ID information can also be stored in association with the amount, type, manufacturing information, owner information, etc. of the game coin 1. By reading the RFID attached to the game coin 1, the game coin reading device 25 can grasp the game coins 1 according to each seat number, and further can grasp the total amount or the number of coins. That is, for example, it can grasp that 4 game coins are placed in seat number 5, and their respective types, amounts, and IDs.

[0181] As Figure 10 shown, based on the image analysis result of the image analysis device 2012, the control device 2014 grasps the total amount or the total number of the game coins 1 for each seat number according to the types and the number of the game coins 1 placed in each placement area of each seat number, compares it with the total amount or the total number of the game coins 1 for each seat number obtained from the information of the RFID of the game coins 1 read by the game coin reading device 25, and determines whether they are consistent. Furthermore, it can output the seat numbers determined to be inconsistent above, and can determine the problematic seat numbers.

[0182] When the total amount or the total number of the game coins 1 for each seat number obtained from the reading result of the game coin reading device 25 is less than the total amount or the total number of the game coins 1 for each seat number obtained from the image analysis result of the image analysis device 2012, it is considered that there may be a situation where the RFID attached to the game coin 1 is damaged, is an unreadable RFID, or the game coin 1 is not attached with an RFID. In Figure 10 it, for the game coins 1 placed in seat number 1, the total number of reads obtained from the image analysis result of the image analysis device 2012 is 4. In contrast, the total number of reads obtained from the RFID reading of the game coin reading device 25 is 3. Therefore, it is considered that one of the 4 game coins 1 placed in seat number 1 has an unreadable RFID.

[0183] When the total amount or total number of game coins 1 for each seat number obtained from the reading result of the game coin reading device 25 is more than the total amount or total number of game coins 1 for each seat number obtained from the image analysis result of the image analysis device 2012, it is considered that there may be a situation where the image analysis device 2012 fails to read the game coin 1 due to reasons such as the game coin 1 entering the blind spot of the camera. In Figure 10 In [specific context], for the game coin 1 placed at seat number 3, the total number of coins read based on the image analysis of the image analysis device 2012 is 1. In contrast, the total number of coins read based on the RFID reading of the game coin reading device 25 is 2. Therefore, it is considered possible that there are 2 game coins 1 placed at seat number 3, but the image analysis device 2012 can only identify 1 coin.

[0184] The ID information of the RFID attached to the game coin 1 is registered in the casino's database, and information on production, shipping at the factory, reception, validation, and activation on the casino side is recorded. 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 coins registered as the game coins to be used in the casino.

[0185] With this structure, it is possible to grasp the types and numbers of game coins 1 placed in each placement area through the camera, and based on the information of the RFID of the game coin 1 read by the game coin reading device 25, determine the authenticity or defective game coins of the game coin 1 for each seat number.

[0186] In addition, the table game management system also has a game participant determination mechanism using a face recognition system or a player ID card, and the control device 2014 can associate the game participant information determined by the game participant determination mechanism with the seat number. The control device 2014 can store for each game participant the placement amount, repayment amount, or recovery amount, and win-loss information stored for each seat number. In addition, information on the games played by the game participant at multiple gaming tables can be stored together.

[0187] 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 gaming table 2004, and can, based on the win / loss result of the game, after the game ends and settlement is carried out, compare and calculate whether the total amount of game coins 1 in the game coin tray 17 has increased or decreased according to the amount of the lost game coins 1 placed by each player 2006 recovered and the amount of the game coins 9W won by the winning player 2006W paid. The game coin tray determination device can be set to capture the game coins 1 stored in the game coin tray 17 using the camera 2002 and, based on the analysis of the image analysis device 2012, to grasp the total amount of game coins 1 in the game coin tray 17, or can be set to detect the total amount of game coins 1 stored in the game coin tray 17 by setting an RFID reading device in the game coin tray 17.

[0188] In this example, since it is possible to detect cheating and errors based on the win / loss result of the game, information on which type of game coins 1 and how many were placed at which position (P, B, draw, or PAIR) in the placement area 2008, and the increase or decrease amount of the game coins 1 in the game coin tray 17 after the recovery of the lost game coins and the repayment of the won game coins 1, even without knowing the movement of the game coins 1 after the game ends, that is, whether the placed game coins 1 move to the player side or the dealer side, cheating and errors can be detected.

[0189] Among them, for example, in the case of a certain card game, in the card dealing device 2003, by reading the face value of the card C drawn in the game, the win / loss result of the game can be determined according to the rules of the card game. In addition, by using the camera 2002 to photograph the gaming table 2004 and using the image analysis device 2012 to analyze the image, and comparing the analysis result with the game rules by the control device 2014, the win / loss result of the game can also be determined. 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 which type of game coins 1 and how many were placed at which position (P, B, draw, P.P, B.P) in the placement area 2008 by the players at each seat number 7 can be obtained by using the camera 2002 to photograph the game coins 1 placed in the placement area 2008 and analyzing the image by the image analysis device 2012 for each player position 7.

[0190] In addition, the increase or decrease amount of the game coins 1 in the game coin tray 17 before and after the recovery of the lost game coins 1 and the repayment of the won game coins 1 can be calculated as follows: Compare the total amount of the game coins 1 in the game coin tray 17 before the recovery of the lost game coins 1 and the repayment of the won game coins 1 with the total amount of the game coins 1 in the game coin tray 17 after the recovery of the lost game coins 1 and the repayment of the won game coins 1.

[0191] For example, let the total amount of the game coins 1 in the game coin tray 17 before the game starts be Bb, and let the total amount of the game coins 1 in the game coin tray 17 after the game ends and after the recovery of the lost game coins 1 and the repayment of the won game coins 1 be Ba. In addition, in this game, let the total amount of the game coins 1 placed at all the player positions 7 in the P area be bp, let the total amount of the game coins 1 placed at all the player positions 7 in the B area be bb, and let the total amount of the game coins 1 placed at all the player positions 7 in the draw area be bt. For example, when the winning or losing result of this game is that the B player wins, Ba - Bb = bp - bb + bt should hold. Or, the total amount Ba of the game coins 1 in the game coin tray 17 after the game ends should be (Bb + bp - bb + bt). When the above situation does not hold, it can be determined that there is cheating or an error in the recovery or repayment of the game coins.

[0192] In Figure 14A is a detailed diagram showing the game coin tray of the present embodiment, Figure 14B is a diagram showing another example of the game coin tray. In the game coin tray 17, there are provided: a recovered game coin tray 171 that recovers and temporarily stores the game coins 1L placed by the losing player 2006L; and a repayment game coin tray 172 that stores the repaid game coins 1W. 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 increased amount of the game coins 1L in this game (the required amount of the game coins 1L in the recovered game coin tray 171). Furthermore, the image analysis device 2012 and the control device 2014 grasp the actual total amount of the game coins 1L in the recovered game coin tray 171 after recovery, compare the required total amount with the actual total amount, and determine whether there is a difference.

[0193] Furthermore, the control device 2014 can perform the repayment of the game coins 1 corresponding to the repayment, and at the end of the repayment, compare the required total amount of the game coin tray obtained based on the amount of the game coins to be repaid in this game with the actual total amount of the game coin tray, and determine whether there is a difference between the required total amount and the actual total amount, and the amount of the game coins to be repaid in this game is calculated based on the position, type, and number of the game coins placed by each game participant on the game table and the game result.

[0194] In addition, the repayment of 1W game coins to the winning player 2006W can be achieved by using the 1W game coins in the repayment game coin tray 172, thereby ensuring that the image analysis device 2012 and the control device 2014 have sufficient time required to grasp the actual total amount of the 1L game coins in the recycled game coin tray 171 after recycling.

[0195] As described above, in this embodiment, the control device 2014 calculates the income and expenditure of game coins based on the amount of game coins placed on the gaming table 2004 and the winning or losing result of each game, and verifies the increase in the balance in the game coin tray 17 after the game. If a difference is detected in this verification, the control device 2014 issues a warning or adds a record indicating the detected difference to the record of the image captured by the camera 2002. The operator on the casino side can explore the cause of the difference by confirming the image.

[0196] In the management system of the table game of this embodiment, the total amount of the 1 game coins in the game coin tray 17 before each game settlement is added or subtracted by the increase or decrease amount of the game coins in this game calculated based on the position, type, and number of the 1 game coins placed by all players 2006 in this game and the winning or losing result of this game obtained by the winning or losing result determination device, and the expected total amount of the 1 game coins in the game coin tray 17 after the settlement at the end of this game is compared with the actual total amount of the 1 game coins in the game coin tray 17 at the end of this game obtained by means of the image analysis device 2012, and it is determined whether there is a difference between the expected total amount and the actual total amount.

[0197] The control device 2014 grasps the position, type, and number of the game coins placed by each player by means of the image analysis device 2012. When the collection of all the lost game coins placed by each player is completed, the control device 2014 grasps the actual total amount of the game coins in the game coin tray, compares the expected total amount of the 1 game coins in the game coin tray 17 with the actual total amount of the 1 game coins in the game coin tray 17, and determines whether there is a difference between the expected total amount and the actual total amount. The expected total amount of the 1 game coins in the game coin tray 17 is obtained by adding the total amount in the game coin tray before each game settlement to the increase amount of the game coin tray 17 in this game based on the position, type, and number of the game coins placed by the losing players.

[0198] The control device 2014 compares the total amount of game coins 1 in the game coin tray 17 before the settlement of each game plus the increased amount of the game coin tray 17 in this game obtained based on the position, type, and number of game coins 1 placed by the losing player with 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 total amount that should be and the actual total amount, and the total amount that should be in the game coin tray 17 after settlement at the end of this game is compared with the actual total amount of game coins 1 in the game coin tray 17 obtained by means of the image analysis device 2012, and it is determined that there is a difference between the total amount that should be and the actual total amount, it is determined as a payment error, and a payment error signal notifying the payment error is generated.

[0199] A recycling game coin tray 171 is provided in the game coin tray 17. The recycling game coin tray 171 recycles and temporarily stores the game coins 1L placed by the losing player. The image analysis device 2012 compares the total amount that should be of the game coins 1L in the recycling game coin tray 171 with the actual total amount of the game coins 1L in the recycling game coin tray 171, and determines whether there is a difference between the total amount that should be and the actual total amount. The total amount that should be of the game coins 1L in the recycling game coin tray 171 is obtained by adding the increased amount of the game coins 1 in this game calculated based on the position, type, and number of game coins 1L placed by the losing player.

[0200] When the control device 2014 determines that there is a difference between the actual total amount of game coins 1 held in the game coin tray 17 of the dealer 2005 of the gaming table 2004 and the increase or decrease amount of the game coins calculated based on the game coin amounts placed by all players and the winning and losing results of this game, in order to be able to analyze the game records where the above differences occur in the game recording device 2011, the game recording device 2011 can index or timestamp the acquired images, or determine and reproduce the recycling scene or payment scene of the game coins 1.

[0201] 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 by means of the image analysis device 2012. However, the determination after settlement in this case refers to the moment when any one of the following 1) to 4) occurs:

[0202] 1) When the repayment of the won game coins 1 ends;

[0203] 2) When the cards C used in this game are recycled and discarded in the discard area 41 or discard slot 42 of this table;

[0204] 3) When a specified button attached to the winning and losing result determination device is pressed;

[0205] 4) When the sign 43 indicating win or loss is restored.

[0206] In addition, the control device 2014 is an artificial intelligence effective utilization type or deep learning structure as follows: It can grasp the positions (positions where P, or B, or PAIR are placed) and amounts (types and numbers) of the game coins placed at each player position 7 on the gaming table 2004, compare the win-loss history of each player 2006 obtained from the win-loss results of each game and the obtained game coin amount (winning amount) with the statistical data of a large number (big data) of past games, and extract abnormal situations (set by the casino). Typically, it is a device of the control device 2014 having an artificial intelligence effective utilization type or deep learning structure as follows: The occurrence of a winning amount of a certain amount (1 million points) or more, or the state where the amount of game coins placed when losing at a certain player position 7 on the gaming table 2004 is small while the amount of game coins placed when winning is large persists in multiple games. By comparing this situation with the statistical data (big data, etc.) of past games, this can be extracted as an abnormal situation.

[0207] Furthermore, the control device 2014 of the management system of this tabletop game (integrated with the image analysis device 2012) is structured to be able to identify the individual player 2006 at the player position 7 where the abnormal situation is extracted or at the player position 7 where a player has won a specified amount or more. For the identification of such a player 2006, in the image analysis device 2012, an image of the face is obtained through feature point extraction or the like, and an identification number (ID, etc.) is assigned to determine it. And the control device 2014 has a warning function of notifying the existence of the specific player to another gaming table when the specific player 2006 leaves the seat and sits at another gaming table. Specifically, it notifies the game table manager or the person in charge of each table (it can also be the dealer) who manages each gaming table 2004 to prevent more abnormal phenomena.

[0208] The control device 2014 can determine the game coins 1 recovered for each seat number based on the ID information of the RFID of the game coins 1 determined by the game coin tray determination device and the ID information of the RFID of the game coins 1 read by the game coin reading device 25.

[0209] In Figure 11 as Figure 12 and Figure 13As shown in the detailed table, place the game coins 1. Based on the analysis of the image analysis device 2012, it is possible to grasp the location (P's place, B's place, etc.) and the number (and amount) of the game coins 1 placed. On the other hand, based on the reading of the game coin reading device 25, it is possible to grasp the ID of the RFID attached to the game coin 1 for each seat number. Furthermore, since the game coin tray determination device can determine the ID of the game coin 1 in the game coin tray 17, it is possible to grasp the ID increased before and after recycling, and thus it is possible to grasp the recycled game coin 1. In Figures 11 to 13 In the case where the game result is that B's place wins, according to the analysis result of the image analysis device 2012, it can be known that the 2 game coins placed at B.P should be recycled, and among the IDs of the recycled game coins determined by the game coin tray determination device, the 2 game coins with ID6 and ID18 read by the game coin reading device 25 for the game coins placed at seat number 5 are recycled.

[0210] Furthermore, the control device 2014 can grasp the total amount or total number of the game coins 1 to be recycled for each seat number determined by using the game result obtained by the game result determination device and the detection results of the position, amount, and number of the 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 the recycled game coins 1 for each seat number determined based on RFID with the total amount or total number of the game coins 1 to be recycled based on the image analysis result, and determine whether they are consistent.

[0211] For example, when the reading result of the game coin reading device 25 for seat number 1 is "A, B, C, D, E", the analysis result of the image analysis device 2012 is "2 for a draw, 2 for B's place", the game result is "B's place wins", and the reading result of the game coin tray determination device 18 is "A, B", it can be known that the game coins A and B placed for the draw are correctly recycled.

[0212] Furthermore, the control device 2014 can determine whether the ID information of the RFID of the recycled 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 is possible to determine whether the game coin 1 recycled by the game coin tray is the game coin placed on the gaming table and whether it is a game coin recycled improperly from other places.

[0213] Furthermore, the control device 2014 can determine the types of game coins such as transcoding and promotion codes based on the RFID information read by the game coin reading device 25, and can store the placed amount, recycled amount, or repayment amount for each determined type of game coin.

[0214] The transcoding is a special game currency that specific members can purchase, and the transcoding is managed according to the amount purchased by each member. By reading the RFID information read by the game currency reading device 25, the amount of the placed or recycled transcoding is stored, so that the amount of the transcoding that a specific member should hold can be grasped.

[0215] The game currency reading device 25 also has the function of a confirmation area and can read the game currency 1 placed for repayment. As Figure 15 shown, when repaying to Family B with seat number 2, the game currency 1 for repayment is placed in the game currency reading device 25 and read. In Figure 15 , it is placed next to the winning game currency 1 placed by Family B with seat number 2. The control device 2014 can compare the repayment amount determined by using the measurement results of the position, amount, and number of game currency 1 obtained based on the game result obtained by the game result determination device and the image analysis result of the image analysis device, with the amount of the game currency 1 placed for each seat number obtained based on the reading result of the game currency reading device 25, and determine and output whether the repayment amounts are consistent. In Figure 16 , the total number of game currency 1 to be paid for seat number 1 is 4. In contrast, the reading result of the game currency reading device 25 is 3, so they are inconsistent. When the repayment amounts are inconsistent, a signal of inconsistency is output, and the dealer can re-place the game currency 1 for repayment based on the output signal. When re-placing the game currency 1, the determination can be made again, and the determination result can be output. The area for placing the game currency 1 for repayment can be any position within the game currency reading device 25. In addition, as Figure 15 shown, the payment confirmation area 26 can be arranged on the dealer side of the placement area separately from the placement area. In Figure 15 , the game currency 1 for repayment is placed in the payment confirmation area 26 with seat number 6, the game currency reading device 25 reads it, the control device 2014 makes a determination, and the repayment game currency is placed next to the winning game currency 1 placed by Family B.

[0216] In addition, image analysis of the image analysis device 2012 is also performed on the confirmation area, and the control device 2014 compares it with the reading result of the game currency reading device 25 and determines whether the total number is consistent.

[0217] The control device 2014 can output a signal based on the implemented determination. The signal can be output in a way that it is displayed on the display part of the game currency tray 17 or the display part of the card distribution device 2003, or the signal can be output by the game table manager or the backstage of the casino.

[0218] The game currency reading device 25 can be as Figure 17As shown, all the placement areas are regarded as a reading area according to each seat number. Alternatively, as Figure 18 shown, for each seat, the P-family placement area and the B-family placement area are regarded as a reading area, and the draw placement area, the P-family placement area, and the B-family placement area are regarded as a reading area. Additionally, as Figure 19 and Figure 22 shown, the side placement areas of the draw pair placement area, the P.P placement area, and the B.P placement area can also be regarded as a reading area respectively.

[0219] Next, the game coin 1 used in the embodiment of the present invention will be described. Figure 20 is an external view of the game coin 1 used in this system, Figure 21 and is a front sectional view. The game coin 1 is formed into the following multi-layer structure: a plurality of plastic layers with different colors are laminated, and at least a coloring layer 101 is provided in the middle. A white layer 102 or a light-colored layer (although not shown, but as long as it is a layer lighter in color than the coloring layer 101) is laminated on both sides of the middle coloring layer 101. By having such a multi-layer structure with the coloring layer 101 and laminating the white layer 102 or the light-colored layer (although not shown, but as long as it is a layer lighter in color than the coloring layer 101) on both sides of the middle coloring layer 101, as Figure 20 shown, stripe patterns in the lamination direction are formed on the side surface. By changing the color of the coloring layer 101 (such as red, green, yellow, blue, etc.), the type of the game coin 1 (such as 10 points, 20 points, 100 points, 1000 points, etc.) can be determined.

[0220] The coloring layer 101 can also be formed by a plurality of colored layers (3 layers in Figure 21 ) as Figure 21 shown. Since the plurality of colored layers (3 layers in Figure 21 ) are thermally press-bonded to each other, as Figure 21 shown, the 3-layer structure is not in a visible state, Figure 21 and the 3 layers shown are for illustrative purposes. And, a partial hollow portion B is provided in the middle layer of the 3 layers of the coloring layer 101, and an RFID is embedded therein.

[0221] In addition, the game coin 1 is not limited to the structure of laminated plastic layers, and can also have a structure with an appearance the same as that of the coloring layer 101.

[0222] Next, a method for the image analysis device 2012 to analyze the game coin 1 will be described in detail. The image analysis device 2012 performs image analysis on the images recorded by the recording device 11, and identifies at least two colors of the specific color 121 that is at least partially attached to the game coin 1 and the reference color R that is different from the specific color 121 and exists in the image. In addition, the specific color 121 is attached to a specified position of the game coin 1 or is at least partially attached to the game coin 1 in a specified shape. For example, it can be attached as the coloring layer 101, can be attached to the side surface of the game coin 1 in the circumferential direction, or can be attached to the surface of the game coin 1 as a specified mark. In addition, the reference color R can also be, for example, the color of a specific area of the game table 2004, or can be the color attached to a position different from the specific color 121 in the game coin 1.

[0223] The image analysis device 2012 includes, for example, an artificial intelligence device 12a that determines the specific color through deep learning technology or the like, and determines the number and type of the game coins 1 arranged on the game table 2004. The image analysis device 2012 can also determine the position of the game coins 1 on the game table 2004.

[0224] The image analysis device 2012 acquires a plurality of images of the game coin 1 and the reference color R irradiated under different illuminations, and through artificial teaching, learns the acquired images and the correct colors of the specific color 121 and the reference color R of the game coin 1 in each image as teacher data, and makes a learning model 13a (recognition program). In addition, for the images of the game coin 1 and the reference color R irradiated under the same illumination conditions, the relative relationship between the specific color 121 and the reference color R can be obtained by irradiating the specific color 121 and the reference color R under the same illumination. For example, this relative relationship can be used for the recognition of the specific color 121.

[0225] In addition, the image analysis device 2012 can also extract the center line C of the game coin 1 by a method of using a camera 2002 to take pictures and record them as images without using artificial intelligence, and using the results of image analysis to detect features on the image such as shape, brightness, color saturation, and hue.

[0226] The artificial intelligence device 12a also has the following structure: by performing image analysis on the peripheral image within a specified range around the extracted center line C (for example, a range of 8 pixels orthogonal to the center line centered on the center line), at least two colors of the specific color 121 and the reference color R different from the specific color 121 in the peripheral image are identified. In addition, when performing image analysis on the peripheral image within a specified range around the extracted center line C, the image can be directly analyzed, or it can also be analyzed on the basis of image processing such as color enhancement and noise removal to more easily identify the specific color 121.

[0227] In summary, the artificial intelligence device 12a of the image analysis device 2012 has a structure that extracts the center line C from the image of the game coin 1, and identifies at least two colors, namely a specific color 121 and a reference color R different from the specific color 121, in the peripheral image within a specified range centered on the center line C by performing image analysis on the peripheral image. The artificial intelligence device is taught with multiple peripheral images of the game coin 1 and the reference color R irradiated under different illuminations as teacher data.

[0228] In other embodiments of the present invention, the control device 2014 further has a function of determining at least one of the following:

[0229] 1) During each game, from the start of card drawing or from the game start operation of the dealer until before the game win / loss result is displayed by the card dispensing device, whether there is no change in the game coins.

[0230] 2) After each game, during the period when the dealer recovers the game coins placed by the losing players among the game participants, whether there is no change in the game coins caused by anyone other than the dealer.

[0231] 3) After each game, during the period when the dealer recovers the game coins placed by the losing players among the game participants, whether game coins are added.

[0232] 4) After each game, whether the dealer pays for the position of the game coins placed by the winning players among the game participants.

[0233] 5) After each game, whether the winning players among the game participants take the placed game coins and the paid game coins.

[0234] Furthermore, the control device 2014 may also be configured to detect the movements of the hands of the dealer and the game participants, the movements of the game coins, or the movements of the hands and the game coins by using the analysis results of the image analysis device 2012, so as to determine at least one of the above 1) to 5).

[0235] The control device 2014 has the functions shown in the following 1) to 5) according to the rules of a certain card game. As the characteristic functions of the present application invention, it determines whether cheating in violation of the rules has occurred. That is,

[0236] 1) In each game, during the period from the signal of the draw of the starting card obtained from the card dispensing device 2003 or from the start operation of the game performed by the dealer 2005 pressing the start button for 4 s until the winning or losing result of the game is displayed by the card dispensing device 2003, it is monitored whether there is no change in the game coins 1 by using the information obtained by the image analysis device 2012 with the camera 2002.

[0237] 2) After each game ends, during the period when the dealer 2005 recovers the game coins 1 placed for the losers among the game participants 2006, it is monitored whether the losers 6 take the game coins 1 without cheating by using the information obtained by the image analysis device 2012 with the camera 2002.

[0238] 3) After each game ends, during the period when the dealer 2005 recovers the game coins 1 placed for the losers among the game participants, it is monitored whether a person other than the dealer 2005 (the winner or the loser) adds the won game coins 1W or does not re - place the game coins 1 on the winning side where they were not placed by using the information obtained by the image analysis device 2012 with the camera 2002.

[0239] 4) After each game ends, it is monitored whether the dealer 2005 correctly places the paid game coins 1W at the position where the game coins 1 are placed for the winners among the game participants 2006 by using the information obtained by the image analysis device 2012 with the camera 2002.

[0240] 5) After each game ends (the dealer 2005 operates the card dispensing device 2003 and the display lamp 13 shows the winning or losing result), it is monitored whether the winners 6W among the game participants 2006 take the placed game coins 1 and the paid game coins 1W by using the information obtained by the image analysis device 2012 with the camera 2002.

[0241] In addition, in the above-described embodiments, the image analysis device 2012 and the control device 2014 are devices having an artificial intelligence effective utilization type or a deep learning structure. Specifically for the image analysis device 2012 and the control device 2014, it can be the Scale-Invariant Feature Transform (SIFT) algorithm, the Convolutional Neutral Network (CNN), deep learning, machine learning, or the analysis of images and the above various controls using the same method. These technologies are technologies for performing image recognition on captured images to recognize the objects included in the images. In particular, in recent years, deep learning technologies that stack multiple layers of neural networks have been used to accurately recognize objects. This deep learning technology generally stacks layers across multiple stages in the intermediate layer between the input layer and the output layer of the neural network to accurately recognize objects. Among this deep learning technology, in particular, the convolutional neural network has attracted attention because it has higher performance than recognizing objects based on existing image feature amounts.

[0242] In a convolutional neural network, an object image with a label attached is learned, and the main object included in the object image to be recognized is recognized. When there are multiple main objects in the learning image, they are specified by a region rectangle, and a label is attached to the image corresponding to the specified region for learning. Furthermore, in a convolutional neural network, it is also possible to determine the main object in the image and the position of the object.

[0243] If the convolutional neural network is further described, in the object recognition process, by performing edge extraction processing etc. on the object image to be recognized, candidate regions are extracted based on local features, and then the candidate regions are input into the convolutional neural network. On the basis of extracting feature vectors, classification is performed, and the candidate region with the highest credibility among the classified regions is obtained as the recognition result. The so-called credibility is a quantity indicating the similarity between a certain image region and the main body of the image learned together with the label, and how much higher it is than the similarity of other levels.

[0244] As described above, various embodiments of the present invention have been described. However, of course, the above embodiments can be modified by those skilled in the art within the scope of the present invention, and the devices of the present embodiment can be appropriately modified according to the needs in the applicable game.

[0305] The control device has the following calculation function: using the game results obtained by the game result determination device and the measurement results of the positions, amounts, and numbers of game coins obtained based on the image analysis results of the image analysis device, it calculates the income and expenditure of the casino side on the gaming table for each game's recovery and repayment.

[0306] It may also have:

[0307] The recycling determination function compares the amount of game coins to be recycled in the game with the actual amount of game coins recycled by the game coin tray when the recycling of the lost game coins placed by each game participant is completed, and determines whether there is a difference between the amount to be recycled and the actual amount recycled, so as to determine whether there is cheating or error in the recycling of game coins. Among them, the amount of game coins to be recycled in the game is calculated based on the positions, types, and numbers of game coins placed by each game participant on the gaming table and the game results; and

[0308] The repayment determination function conducts the repayment of the game coins to be repaid. When the repayment is completed, it compares the total amount that the game coin tray should have obtained based on the amount of game coins to be repaid in the game with the actual total amount of the game coin tray. If it is determined that there is a difference between the total amount that should be and the actual total amount, it is determined that there is cheating or error in the repayment. Among them, the amount of game coins to be repaid in the game is calculated based on the positions, types, and numbers of game coins placed by each game participant on the gaming table and the game results.

[0309] In addition, the control device may have the following structure:

[0310] Based on the ID information of the RFID of the recycled 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, it is possible to determine the game coins recycled for each seat number, compare the ID or amount or number of the determined game coins with the ID or amount or number of the game coins to be recycled for each seat number, and determine whether they are consistent for each seat number. Among them, the ID or amount or number of the game coins to be recycled for each seat number is determined using the measurement results of the positions, amounts, and numbers of game coins obtained based on the game results obtained by the game result determination device and the image analysis results of the image analysis device.

[0311] In addition, the control device may have the following structure: In each game, based on the ID information of the RFID of the game coins read by the game coin reading device, it is possible to determine the types distinguished according to the usage purposes or usage objectives of the game coins, and for each seat number, store the amounts placed, or the recycled amounts or repayment amounts, according to each of the types of the game coins.

[0312] In addition, the control device may have the following structure: In multiple games, it is possible to store, for each seat number, the cumulative amounts placed, or the cumulative recycled amounts or cumulative repayment amounts, according to each type of the game coins.

[0313] In addition, the types of the game coins may at least include conversion codes or promotion codes.

[0314] In addition, the control device may have the following structure: it can determine the owner based on the ID information of the transcoding, and for each owner, store the cumulative amount of the transcoding placed, or the cumulative amount recovered, or the cumulative amount repaid.

[0315] In addition, the game coin reading device reads the game coins for repayment placed in the game coin reading device for each seat number.

[0316] The control device may have the following structure: it compares the repayment amount determined based on the measurement results of the position, amount, and number of game coins obtained by using the game result and the image analysis result of the image analysis device, and the amount of the game coins placed for each seat number obtained based on the reading result of the game coin reading device, and determines and outputs whether the repayment amounts are consistent or not.

[0317] In addition, the control device may have the following structure: it can display the inconsistency when the determination result of the repayment amount is inconsistent. Furthermore, when the amount of the game coins placed in the game coin reading device for each seat number read by the game coin reading device changes, it makes a determination again and outputs whether it is consistent or not again.

[0318] In addition, the control device may have the following structure: it can compare the amount of the game coins for repayment placed for each seat number with the increase or decrease amount of the game coin tray before and after repayment, and determine whether there is a difference.

[0319] In addition, the game coin reading device may have a payment confirmation area on the dealer side disposed in the placement area for placing the game coins for repayment.

[0320] In addition, a game participant determination mechanism using a face recognition system or a player ID card may be provided.

[0321] The control device may have a structure capable of associating the seat number with the information of the game participant determined by the game participant determination mechanism.

[0322] In addition, a display device is provided, which performs display based on the output of the control device.

[0323] In addition, the gaming table further has a side placement area.

[0324] The side placement area is provided so as to be adjacent to each placement area of each seat number.

[0325] The game coin reading device can read at least one of the side placement areas together.

[0326] The control device may have the following structure: based on the image analysis result of the image analysis device, it can grasp the types and quantities of the game coins placed in at least one of the side placement areas, and determine whether the total amount or total quantity of the game coins in at least one side placement area obtained from the image analysis result of the image analysis device is consistent with the total amount or total quantity of the game coins in this side placement area obtained from the reading result of the game coin reading device, and output a signal of the determination result.

[0327] In addition, other embodiments of the present invention are management systems for the following tabletop games.

[0328] It has:

[0329] Game coins, which are attached with RFID that can be respectively identified;

[0330] A game table, which is used to play games with the game coins;

[0331] A game recording device, which records the game coins placed by each game participant in the game on the game table as images by means of a camera;

[0332] An image analysis device, which performs image analysis on the recorded images of the game coins;

[0333] A game coin reading device, which reads the RFID attached to the game coins placed by each game participant; and

[0334] A control device, which grasps the image analysis result of the image analysis device and the reading result of the game coin reading device.

[0335] The game table is provided with a placement area composed of a P-family placement area, a B-family placement area, and a side placement area.

[0336] The side placement area is set in a manner adjacent to each placement area of each seat number.

[0337] The game coin reading device can read at least one of the side placement areas together.

[0338] The control device has the following structure: based on the image analysis result of the image analysis device, it can independently determine the type and number of the game coins placed in at least one of the side placement areas, and determine whether the total amount or total number of the game coins in at least one side placement area obtained based on the image analysis result of the image analysis device is consistent with the total amount or total number of the game coins placed on this side obtained based on the reading result of the game coin reading device, and output a signal of the determination result.

[0339] In addition, the control device can be structured to output the side placement where the determination result is inconsistent.

[0340] In addition, the control device can also have the following structure: when the total amount or total number of the game coins placed on each side obtained based on the reading result of the game coin reading device is less than the total amount or total number of the game coins placed on each side obtained based on the image analysis result of the image analysis device, it can generate a signal indicating that the RFID attached to the game coin may be damaged or that the game coin may not have an RFID attached.

[0341] In addition, the control device can also have the following structure: when the total amount or total number of the game coins in each side placement area obtained based on the reading result of the game coin reading device is more than the total amount or total number of the game coins in each side placement area obtained based on the image analysis result of the image analysis device, it can generate a signal indicating that there may be an error in reading the game coin by the image analysis device.

[0342] In addition, there is also a database that stores the IDs of the RFID attached to the game coins.

[0343] The control device can be structured to compare the ID of the RFID obtained based on the reading result of the game coin reading device with the ID stored in the database to determine the authenticity of the game coin.

[0344] In addition, the control device may have the following structure: based on the ID information of the RFID of the recycled 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, it can determine the recycled game coins placed on each side, and compare the ID or amount or number of the game coins to be recycled in the placement area for each side placement determined below with the ID or amount or number of the recycled game coins in each placement area for each side placement, and determine the consistency or inconsistency of the recycled amount for each placement area for each side placement. Among them, the determination of the ID or amount or number of the game coins to be recycled in each placement area for each side placement is obtained by using the measurement results of the position, amount, and number of the game coins based on the game result obtained by the game result determination device and the image analysis result of the image analysis device.

[0345] (Fourth Embodiment)

[0346] Hereinafter, a fourth embodiment of the present invention will be described.

[0347] (First Example)

[0348] Figure 23 FIG. is a diagram showing the structure of a management system according to a first example of the fourth embodiment of the present invention. The management system 110 does not use a database to track the owner of the game coins. For this reason, the owner's information is stored in the game coins. The management system 110 includes a substantially elliptical gaming table 4004. The player 82 is located on one side ( Figure 23 the lower side) of the gaming table 4004, and the dealer is located on the opposite side (not shown). The upper surface of the gaming table 4004 is divided into placement areas 41a to 41e (hereinafter, collectively referred to as "placement area 41") for each of a plurality of player positions. The placement area 41 is an area for the player 82 to play by placing his game coins 83. A game coin tray 12 for placing the dealer's game coins 83 is provided on the dealer position side of the gaming table 4004.

[0349] The game coin 83 has the same structure as the game coin in the above embodiment. That is, the game coin 83 is embedded with an RFID tag 2, and the RFID tag 2 includes a non-rewritable area 21 for storing fixed information 3 and a rewritable area 22 for storing variable information 4. The RFID tag 2 stores a game coin ID (identification information) for uniquely identifying the game coin 83 as the inherent information 3. In addition, the RFID tag 2 stores a user ID for uniquely identifying the owner of the game coin 83 as the variable information 4.

[0350] Note that when a common user ID is attached to the casino or the dealer and the casino holds the game tokens 83 (including the case where they are stored in the game token tray 12), the change information 4 stores the user ID indicating the casino or the dealer.

[0351] Each placement area 41a - 41e of the gaming table 4004 is provided with RFID antennas 511a - 511e (hereinafter, collectively referred to as "RFID antenna 511" when mentioned together). Specifically, the RFID antennas 511 are respectively embedded at positions below the wool fabric (rascha) of the gaming table 4004 that demarcate the corresponding placement areas 41. In addition, the game token tray 12 is also provided with an RFID antenna 513.

[0352] The RFID antenna 511 reads and writes data to / from the RFID tag 2 embedded in the game token 83 placed in the corresponding placement area 41. The RFID antenna 513 reads and writes to / from the RFID tag 2 embedded in the game token 83 placed in the game token tray 12.

[0353] The RFID antennas 511a - 511e and the RFID antenna 513 are connected to the RF control device 54. Note that in Figure 23 , for ease of reading the drawings, only the line connecting the antenna 511e to the RF control device 54 is shown, and the lines connecting the antennas 511a - 511d to the RF control device 54 are omitted from the illustration. Similar to the antenna 511e, the antennas 511a - 511d are also connected to the RF control device 54. The same applies to the following drawings. The RF control device 54 controls each antenna for reading and writing. The RF control device 54 controls reading and writing by distinguishing each antenna. For this purpose, each antenna is attached with a region ID, which is used to uniquely determine the region where reading and writing are performed through this antenna. In addition, when reading, the RF control device 54 performs reading periodically.

[0354] By comparing this region ID, it is possible to determine whether the read game token 83 is located in the game token tray 12 or in the placement area 41. For the placement area 41, it is also possible to determine which placement area 41a - 41e of the player position it is located in.

[0355] When reading, the RF control device 54 receives the data read by each antenna from that antenna and determines the region ID, which is the region where the data was read. In addition, when writing, the RF control device 54 determines the antenna for writing, that is, the region ID, and sends the write data. Thus, the RF control device 54 can control reading and writing for each antenna separately.

[0356] The RF control device 54 outputs the user ID ( Figure 23 “UserID”) of the game coin 83 and the area ID ( Figure 23 “Area ID”) of the area where the user ID was read, based on the data read by each antenna. The management system 110 also includes a management control device 56 connected to the RF control device 54. The management control device 56 receives the user ID and the area ID from the RF control device 54 and designates the user ID to be written to the RFID tag 2 for the RF control device 54.

[0357] It should be noted that, as described below, the user ID stored in the RFID tag 2 of the game coin 83 changes as the game coin 83 moves. In addition to the latest user ID, the RFID tag 2 also stores past user IDs as change information 4. Thus, by comparing the change information 4, the change of the owner of each game coin 83 can be investigated. In the following description, expressions such as “rewrite user ID” mean at least changing the latest user ID, and do not necessarily mean deleting the information of the past user ID at the same time.

[0358] The management control device 56 updates the change information 4 of the game coin 83 based on the data (user ID and area ID) of the game coin 83 received from the RF control device 54. Hereinafter, the method of updating the change information 4 will be described.

[0359] Figures 24 to 26 A diagram for explaining an example of updating the change information. As Figure 24 shown, the player places the game coin 831 in the placement area 41b. The management control device 56 inputs the user ID of the game coin placed by the player in the placement area (hereinafter, also referred to as “placed game coin 831”) read from the RFID tag 2 and the area ID of the placement area 41b.

[0360] At the placement stage, as Figure 24 shown, the same user ID (in the example of Figure 24 , it is “P1”) is read from the placement area 41b, and the same ID (in the example of Figure 24 , it is “D” indicating that the owner is the casino or the dealer) is also read from the game coin tray 12. In the case where the player wins the game, as Figure 25 shown, the dealer pays (repays) a game coin (hereinafter, also referred to as “paid game coin 832”) from the game coin tray 12 and places it next to the placed game coin 831 in the placement area 41b.

[0361] As a result, in the placement area 41b, in addition to reading "P1" as the user ID, "D" is also read. When there are two types of user IDs for the game coins 83 read from the same placement area 41, and one of them is "D" and the other is the user ID assigned to the player, the management control device 56 controls the RF control device 54 to rewrite the user IDs of all the game coins 83 in the placement area 41 to the user ID assigned to the player (in Figure 25 it is "P1"). It should be noted that in this case, in the placed game coin 831 where "P1" is stored as the user ID, "P1" is similarly added as the latest user ID.

[0362] On the other hand, when the player loses the game, as Figure 26 shown, the dealer recovers the placed game coin 831 into the game coin tray 12. As a result, in the game coin tray 12, in addition to reading "D" as the user ID, "P1" is also read. When there is a user ID other than "D" and assigned to the player among the user IDs of the game coins 83 read from the game coin tray 12 (in the example of Figure 26 it is "P1"), the management control device 56 rewrites the user IDs of all the game coins 83 in the game coin tray 12 to "D".

[0363] It should be noted that there is a recovery floating platform for temporarily storing the game coins 83 recovered into the game coin tray 12. By separating the antenna from other parts through this recovery floating platform, the above-mentioned processing can be performed only on the game coins 83 recovered to the recovery floating platform.

[0364] Through the above processing executed by the management control device 56, the user ID stored in the game coin 83 is updated in response to the change of the actual owner. That is, in the present embodiment, the user ID is stored in the RFID tag 2 of the game coin 83, and since the user ID is updated to make the owner of the payment game coin 832 the same as the owner of the placed game coin 831, even without using the subsequent database and the player determination system, and the management control device 56 does not grasp the progress of the game (placement stage, game stage, settlement stage), it is possible to track the change of the owner caused by the game conducted on the gaming table 4004.

[0365] It should be noted that when the player newly purchases the game coin 83, the player is determined using the subsequent player determination system, the user ID of the casino or the dealer is rewritten to the determined player's user ID, and on this basis, the game coin 83 is handed over to the player.

[0366] (Second example)

[0367] Figure 27A diagram showing the structure of the management system for the second example of the fourth embodiment. In addition to the structure of the management system 110 of the first example, the management system 120 incorporates a player identification system. The player identification system may include an image recognition system composed of a camera 52 and an image recognition device 55, and a card authentication system composed of a membership card 81 and a card reader 53, or may include any one of them.

[0368] The camera 52 captures the face of the player 82 located at the player position and outputs the image generated by the capture to the image recognition device 55. The image recognition device 55 is equipped with a face recognition engine based on a neural network that learns the face images of a plurality of pre-registered players 82 (hereinafter, the registered players are referred to as "members"). The image recognition device 55 inputs the image from the camera 52 into the neural network to determine which member's face image the input face image is. It should be noted that when the image recognition device 55 determines that the image from the camera 52 is not the face of any registered member, it outputs the result that the face image is a non-member's face image.

[0369] In addition, the image recognition device 55 determines the player position of the member based on the position within the image whose face has been authenticated. The image recognition device 55 outputs the user ID of the member corresponding to the image from the camera 52 ( Figure 27 "User ID" in Figure 27 ), and the area ID of the determined player position (

[0370] "Area ID" in Figure 27 ). It should be noted that when the image recognition device 55 cannot determine which member it is, it outputs "Unknown" as the user ID. Figure 27 ).

[0371] The management control device 56 inputs the user ID and area ID stored in the game coin 83 read by the RF control device 54 using the antenna 511, inputs the user ID and area ID determined by the image recognition device 55 based on the player's facial image, and inputs the user ID obtained by the card reader 53 reading the membership card 81 and the area ID specified by the dealer.

[0372] For the same area ID, in the case where the user ID read by the antenna 511, that is, the user ID stored as the owner of the game coin 83 placed in the placement area 41, is inconsistent with the user ID read by the membership card 81 or the user ID determined by the image recognition device 55, that is, the player determined by the player determination system, the management control device 56 controls the RF control device 54 to rewrite the user ID stored as the owner in the change area 4 of the game coin 83 placed in the placement area 41 to the user ID of the player determined by the player determination system.

[0373] The RF control device 54 uses the antenna 511 to write the user ID of the player determined by the player determination system in the rewritable area 22 of the RFID tag 2 of the game coin 83 placed in the placement area 41. At this time, the RF control device 54 can also record in the writable area 22 the situation of rewriting the user ID as the owner information due to the inconsistency of the user ID. Thus, when the casino or the dealer obtains the game coin 83, by comparing the change history record of the owner, it is possible to know that there is a situation where the owners are inconsistent and also to determine the player involved in the inconsistency.

[0374] It should be noted that in the player determination system, only one of determining the player by the face authentication system and determining the player by reading the membership card 81 can be executed. That is, when a registered member sits at the player position, it is not necessary to determine the player by the membership card 81. In this case, the player can be determined only by the face authentication system. In addition, even when the face cannot be successfully photographed and face authentication cannot be performed, the player can be determined by the membership card 81.

[0375] Furthermore, there is a case where the player can be determined by either face authentication or the membership card 81. In this case, there is a situation where the user ID of the player determined by face authentication is different from the user ID of the player determined by the membership card 81. In the case where the user ID of any one of the two is consistent with the user ID read from the game coin 83, the management control device 56 controls the RF control device 54 to record in the writable area 22 of the game coin 83 the user ID that is inconsistent with the user ID read from the game coin 83 and the situation of being inconsistent with the player determined by the player determination system.

[0376] In this example, similar to the first example, the user ID stored in the game coin 83 is updated according to the actual owner. Further, in this example, when the user ID of the player determined by the player determination system does not match the user ID stored in the game coin 83, the discrepancy is corrected, and the situation that caused the discrepancy is recorded in the game coin 83. Thus, by referring to this record of the game coin 83, it is possible to know that there is a transfer of the game coin 83 among players and to identify the players involved in this situation.

[0377] (Third Example)

[0378] Figure 28 FIG. for showing the structure of the management system of the third example of the fourth embodiment. The management system 130 has a database 57 in addition to the structure of the management system 110 of the first example. In the database 57, the game coin ID ( Figure 28 "Chip ID" in ) for uniquely identifying the game coin 83 and the user ID of the player holding the game coin 83 are stored in association with each other. It should be noted that, as described above, since the owner of the game coin 83 changes due to purchase and use in the game, the database 57 records the history of past owners. Thus, by referring to the database 57, it is possible to know the change in the owner of each game coin 83.

[0379] In this example, the game coin 83 may have a non-writable area 21 and no writable area 22. That is, the game coin 83 can store at least the game coin ID. In addition, the RF control device 54 may be an RF reader that only has a reading function and no writing function.

[0380] The management control device 56 updates the database 57 based on the data (game coin ID and area ID) of the game coin 83 received from the RF control device 54. Hereinafter, the method for updating the database 57 will be described.

[0381] Figures 29 to 31 FIG. for explaining an example of updating the database 57. As Figure 29 shown, the player places the game coin 831 on the placement area 41b. The game coin ID of the placed game coin 831 and the area ID of the placement area 41b obtained by reading the RFID tag 2 of the placed game coin 831 by the player are input to the management control device 56.

[0382] In the placement stage, as Figure 29As shown, "C00001" to "C00005" are read as game coin IDs from the placement area 41b, and "C20001" to "C20100" are read as game coin IDs from the game coin tray 12. Further, the RF control device 54 outputs the combination of the game coin IDs read through the antennas 511 and 513 and the area IDs corresponding to the antennas 511 and 513 to the management control device 56. In Figure 29 the example of Figure 29 , in the RF control device 54, combinations of game coin IDs "C00001" to "C00005" and area ID "Area2", and combinations of game coin IDs "C20001" to "20100" and area ID "Area T" (the area ID representing the game coin tray 12) are obtained and output to the management control device 56.

[0383] In the case where the player wins the game, as Figure 30 shown, the dealer pays (repays) the payout game coin 832 from the game coin tray 12 and places it beside the placed game coin 831 in the placement area 41b. In this way, in the RF control device 54, combinations of game coin IDs "C00001" to "C00005" and "C20001" to "C20005" and area ID "Area2", and combinations of game coin IDs "C20006" to "C20100" and area ID "Area T" are obtained and output to the management control device 56.

[0384] The management control device 56 compares all the read game coin IDs with the database 57 and obtains the user IDs associated with the game coin IDs. Further, the management control device 56 compares the combinations of the game coin IDs and area IDs obtained from the RF control device 54, and when the user IDs of multiple game coin IDs associated with the same area ID are different, the database 57 is updated so that these user IDs become the same user ID.

[0385] Specifically, when there are the user ID of the player and the user ID of the casino or the dealer as the user IDs of multiple game coins 83 read in the area ID of the same placement area 41, the management control device 56 rewrites the user ID of the casino or the dealer to the user ID of the player, thereby unifying the user IDs of the game coin IDs forming combinations with the same area ID.

[0386] On the other hand, in the case where the player loses the game, as Figure 31As shown, the dealer retrieves the placed game coins 831 into the game coin tray 12. In this way, in addition to reading "C20001" to "C20100" from the game coin tray 12, "C00001" to "C00005" are also read as game coin IDs. The RF control device 54 obtains the combination of the game coin IDs "C20001" to "C20100" and "C00001" to "C00005" and the area ID "Area T" of the game coin tray 12, and outputs this combination to the management control device 56.

[0387] The management control device 56 compares all the read game coin IDs with the database 57 and obtains the user IDs associated with these game coin IDs. Moreover, the management control device 56 compares the combination of the game coin ID and the area ID obtained from the RF control device 54. When the user IDs of multiple game coin IDs that form a combination with the same area ID are different, the database 57 is updated so that these user IDs become the same user ID.

[0388] Specifically, when there are a player's user ID and a casino's or dealer's user ID as the user IDs of multiple game coins 83 read in the area ID of the game coin tray 12, the management control device 56 rewrites the player's user ID as the casino's or dealer's user ID, thereby rewriting the user IDs of all the game coin IDs associated with the area ID of the game coin tray 12 as the casino's or dealer's user ID.

[0389] Through the above processing of the management control device 56, the user IDs stored in the database 57 are updated according to the actual owners. That is, in this embodiment, for different game coins 83 associated with user IDs existing in the same area, the database 57 is rewritten to unify these user IDs into any one of the user IDs according to the area. Thus, even without using the above player determination system, or even if the management control device 56 does not grasp the progress status of the game (placement stage, game stage, settlement stage), it is possible to track the change of ownership caused by the game conducted on the gaming table 4004.

[0390] In addition, in the above example, the management control device 56 determines that the game coin is the payment game coin 831 based on reading the payment game coin 831 in the placement area 41 and setting the user ID to "D" in the database 57, and rewrites the user ID of this game coin as the player's user ID. As an alternative, it is also possible to determine the game coin ID of the payment game coin 832 based on the difference in the game coin IDs read from the game coin tray 12 before and after payment.

[0391] For example, in Figure 29 and Figure 30In the example, before payment, as Figure 29 shown, game coin IDs "C20001" to "C20100" are read from the game coin tray 12. On the contrary, after payment, as Figure 30 shown, game coin IDs "C20006" to "C20100" are read from the game coin tray 12. Thus, based on this difference, the management control device 56 can determine that game coin IDs "C20001" to "C20005" are the game coin IDs for payment.

[0392] (Fourth example)

[0393] Figure 32 FIG. is a diagram showing the structure of the management system for the fourth example of the fourth embodiment. The management system 140 includes, in addition to the structure of the management system 110 of the first example, a player identification system, a database 57, and a card issuing device (electronic shoe) 4003. Further, in the gaming table 4004, payment areas 42a to 42e (hereinafter, when collectively referred to, denoted as "payment area 42") are provided on the dealer side closer to the dealer than the placement areas 41 of each player position. Further, antennas 512a to 512e (hereinafter, when collectively referred to, denoted as "antenna 512") are provided corresponding to the respective areas in the payment areas 42a to 42e.

[0394] When the dealer pays (repays) game coins 83 to the player 82 who has won the game, after placing the game coins 83 taken out from the game coin tray 12 in the payment area 42 of the winning player 82, they are placed in the placement area 41 of that player 82.

[0395] The camera 52 in this example captures not only the player 82 but also the placed game coins 831 placed in the placement area 41. Further, the image recognition device 55 performs image recognition processing not only on the face of the player but also on the placed game coins 831 in the placement area 41 to recognize which placement object (P, B, draw, P.P, B.P, etc.) in the placement area 41 the placed game coins 831 in the placement area 41 are placed on, and outputs the recognition result as the placement content ( Figure 32 in "

[0396] It should be noted that the camera that captures the face of the player 82 and the camera that captures the placed game coins 831 may be different cameras. Further, the image recognition device that determines the player based on the face image of the player and the image recognition device that recognizes the placement content based on the image of the placed game coins 831 may be different devices.

[0397] In this example, the card issuing device 4003 determines the progress status of the game (i.e., any one of being placed, in the game, and in settlement) and outputs it to the RF control device 54. When the first card is drawn, the card issuing device 4003 determines the start of the game and, according to a certain card game rule, determines the end of the game based on the reading result of the drawn card. In addition, when the game start button is pressed, the card issuing device 4003 determines the end of settlement and starts placement.

[0398] In addition, the card issuing device 4003 determines the game results such as the win of player P, the win of player B, a draw, P.P., B.P., etc. according to a certain card game rule by at least reading the face value of the drawn card.

[0399] The management control device 56 determines which player position receives payment based on the placement content obtained from the image recognition device 55 and the game result obtained from the card issuing device 4003. The management control device 56 also obtains the user ID of the player at each player position from the image recognition device 55 or the card reader 53. Therefore, based on this information, it can be determined which player has received payment.

[0400] When the game progress status received from the card issuing device 4003 is in settlement, the RF control device 54 activates the antenna 512 in the payment area 42 to read and write the RFID tag of the game coin 83.

[0401] When the user ID associated with the game coin ID of the payment game coin 832 read in the payment area 42 is the user ID of the casino or the dealer in the comparison with the database 57, the management control device 56 rewrites the user ID with the user ID associated with the game coin ID of the placed game coin 831 placed in the corresponding placement area 41 at this time.

[0402] It should be noted that when the dealer recovers the placed game coin 831 of the losing player, the antenna 512 in the payment area 42 may read the game coin ID of the placed game coin 831. In this case, the game coin ID read in the payment area 42 is the same as the game coin ID read in the corresponding placement area 41 before. Thus, it is determined that the game coin ID is read in the payment area 42 during recovery. In this case, the user ID of the game coin 83 read in the payment area 42 is not rewritten.

[0403] Note that, in this example, the management system 140 having a player determination system, a database 57, and a card issuing device (electronic shoe) 4003 is described. However, similar to the first example, in a management system that does not have a player determination system, a database 57, and a card issuing device (electronic shoe) 4003, a payment area 42 and an antenna 512 corresponding to the payment area can be set in the same manner as in this example, and the user ID can be updated.

[0404] In the management system 140 of this example, the payment area 42 is set, and the RFID tag of the game currency 83 is read and written separately from the placement area 41, so that the reading and writing of the payment game currency 832 paid from the game currency tray 12 can be performed at high speed. That is, as shown in the first to third examples above, for the payment game currency 832, if the reading and writing are performed using the antenna 512 in the same manner as the placed game currency 831, in order to read and write the payment game currency 832, the reading and writing of the placed game currency 831 also need to be performed, so it takes time. However, in the payment area 42, only the payment game currency 832 can be read and written. Therefore, the reading and writing can be performed in a shorter time, and it will not cause a great obstacle to the operation of the game.

[0405] (Fifth Example)

[0406] Figure 33 A diagram showing the structure of the management system of the fifth example of the fourth embodiment. The management system 150 has the same structure as the Figure 32 management system 140 of the fourth example shown. That is, in addition to having the structure of the management system 110 of the first example, the management system 150 also has a player determination system, a database 57, and a card issuing device (electronic shoe) 4003.

[0407] The camera 52 in this example not only captures the player 82 but also captures the placed game currency 831 placed in the placement area 41. In addition, the image recognition device 55 performs image recognition processing not only on the face of the player but also on the placed game currency 831 in the placement area 41, recognizes which placement object (P, B, draw, P.P, B.P, etc.) the placed game currency 831 in each placement area 41 is placed in the placement area 41, and outputs the recognition result as the placement content ( Figure 33 "placement" in).

[0408] Note that the camera that captures the face of the player 82 and the camera that captures the placed game currency 831 can be different cameras. In addition, the image recognition device that determines the player based on the face image of the player and the image recognition device that recognizes the placement content based on the image of the placed game currency 831 can be different devices.

[0409] The card issuing device 4003 determines the game results including P's win, B's win, draw, PP, and BP according to the rules of a certain card game by at least reading the face value of the cards drawn in sequence.

[0410] The management control device 56 determines which player position accepts payment (repayment) based on the placement content acquired from the image recognition device 55 and the game result acquired from the card issuing device 4003. The management control device 56 also acquires the user ID of the player at each player position from the image recognition device 55 or the card reader 53, and can therefore determine which player accepts (repayment) based on this information.

[0411] For each placement area 41, a combination of the area ID of the placement area 41 and the game coin ID of the game coin 831 placed read in the placement area 41 is input from the RF control device 54 to the management control device 56. As described above, the management control device 56 determines which player position receives the payment, and therefore, compares the database 57 and obtains the user ID associated with the game coin ID read at the player position receiving the payment, and updates the user ID associated with the game coin ID of the payment game coin 832 paid through the obtained user ID.

[0412] It should be noted that the management control device 56 identifies the game coin ID that is not read from the game coin tray 12 before and after the payment as the game coin ID of the payment game coin 832. In addition, when there are multiple players who accept the payment, the dealer pays in sequence from one end to the specified direction (for example, from one end of the right hand side of the dealer to one end of the left hand side in sequence). Thus, even if there are multiple players who accept the payment, it is possible to determine which player position or player the payment game coin 832 taken out from the game coin tray 12 is taken out for.

[0413] Furthermore, the management control device 56 is able to determine the player position of the losing player, and therefore updates the database 57 to associate the token ID read from the placement area 41 of the player position with the user ID as "D" indicating the casino or dealer.

[0414] As described above, in this example, the management control device 56 grasps the placement content and game results, and therefore can determine which player or player position has paid for the placed game coin 831, which player or player position has recovered the placed game coin 831, and can also determine the game coin IDs of these placed game coins 831 and paid game coins 832, so in the database 57, it can be determined for which game coin IDs to update the associated user ID, and which user ID should be changed. Thus, the owner of the game coin 83 can be tracked.

[0415] (Sixth Example)

[0416] Figure 34 FIG. showing the structure of the management system of the sixth example of the fourth embodiment. The management system 160 has the same structure as that of the second example. In a certain card game, as described above, a plurality of player positions are provided on the gaming table 4004, and a placement area 41 is provided for each player position corresponding to each player position on the gaming table 4004. In principle, one player plays the game at one player position.

[0417] However, when all the player positions are occupied, behind the player (seated player) playing the game at the player position, there will also be a player (rear placer) placing on the placement area 41 assigned to the seated player, and such placement is allowed according to the casino or the gaming table 4004. Due to the rear placement, a plurality of game coins 83 with different user IDs are placed in the same placement area. The management system 160 of this example can track the owner of the game coin 83 even in such a situation.

[0418] In the management system 160 of this example, similar to the second example, the user ID of the game coin 83 is stored in the rewritable area 22 of the RFID tag 2 of the game coin 83, without using a database. However, there is a player determination system for determining the player.

[0419] In Figure 35 example, a placed game coin 831a with user ID "P1" and a placed game coin 831b with user ID "P2" are placed in the same placement area 41b. At this time, as the user ID of the game coin 83, "P1" and "P2" can be read from the placement area 41b.

[0420] Figures 36 to 38 FIG. illustrating an example of payment in the case where both players win the game. First, as Figure 35 shown, payment is made to the player 82a with user ID "P1". At this time, the management system 160 cannot distinguish whether it is paying the player 82a with user ID "P1" or the player 82b with user ID "P2", and for the plurality of game coins 83 existing in one placement area 41, the written information cannot be made different. Therefore, the management control device 56 controls the RF control device 54 to rewrite the user ID of all the game coins 83 existing in the placement area 41b into selective information such as "P1 or P2".

[0421] The player 82a who receives the payment takes his placed game coin 831a and payment game coin 832a from the placement area 41b, as Figure 37As shown, the remaining game tokens 831b with user ID "P1 or P2" are placed in the placement area 41b. The dealer confirms that the player 82a has taken the game tokens 83, and as Figure 38 shown, pays out the payment game tokens 832b with user ID "D" for the placed game tokens 831b. At this time, the management control device 56 controls the RF control device 54, and rewrites the user ID of all the game tokens 83 in the placement area 41 to "P1 or P2".

[0422] Thus, both players 82a and 82b who place tokens in the same placement area 41 have game tokens 83 with the user ID recorded as "P1 or P2".

[0423] Suppose that when these players 82a and 82b use these game tokens 83 to place tokens again in the same placement area 41, both the placed game tokens 831a and 831b record "P1 or P2" as the user ID. Or, there is a case where some of the placed game tokens include game tokens 83 with user ID "P1" or "P2". In these cases, when making payments according to the game results, the management control device 56 controls the RF control device 54, and when making payments, selectively writes "P1 or P2" as the user ID of all the game tokens 83 placed in the placement area 41.

[0424] It should be noted that when the placed game tokens 831 with user ID "P1 or P2" are recycled into the game token tray 12, "D" representing the casino or the dealer is written as the user ID.

[0425] After that, when players 82a and 82b separately place game tokens 83 with selectively recorded user IDs of multiple users in the placement area 41, if the user ID of the player determined by the player determination system is consistent with any one of the user IDs in this option, the management control device 56 controls the RF control device 54, and rewrites the selective user ID of the game token 83 to the consistent user ID.

[0426] For example, when player 82a separately places a game token 83 with user ID "P1 or P2" in the placement area 41, the user ID "P1 or P2" is read from the placed game token 831 in the placement area 41 through the RF control device 54, and the user ID of the player placed in the placement area 41 is identified as "P1" by the player determination system. In this case, since the user ID "P1" is consistent, the management control device 56 controls the RF control device 54, and rewrites the user ID of the placed game token 831 in the placement area 41 to "P1".

[0427] On the other hand, when a player with a game coin 83 in which the user ID is selectively recorded makes a placement, in the same placement area 41, if a player with a user ID not present in the options makes a placement, when receiving payment according to the game result, the user ID of the game coin 83 is also selectively written as the user ID of this player so as to be included in the options.

[0428] For example, when the player 82a places a game coin 83 with the user ID "P1 or P2" recorded in the placement area 41, and in the same placement area 41, if another player places a game coin 83 with the user ID "P3" recorded, when making payment according to the game result, the management control device 56 controls the RF control device 54 to rewrite the user ID of all the game coins 83 including the payment game coin in this placement area 41 as "P1 or P2 or P3".

[0429] As described above, in this example, selectively recording the user ID is allowed, and even when multiple players make placements in the same placement area, the owner can be traced. Further, by using the player determination system, the selectively recorded user ID can be reliably rewritten.

[0430] It should be noted that when multiple players make placements in the same placement area 41, and some players win and some players lose, first, the placed game coins of the losing players are recycled. Therefore, when the game coin tray 12 reads the recycled placed game coins, "D" can be recorded as the user ID, and the above processing is performed on the placed game coins that receive the expenditure of the payment game coin 832 and the payment game coins that pay for the placed game coins.

[0431] (Seventh Example)

[0432] Figure 39 A diagram showing the structure of the management system for the seventh example of the fourth embodiment. The management system 170 has the same structure as the management system 130 of the third example. In the management system 170, even when multiple players make placements in the same placement area 41, the owner of the game coin 83 can be traced.

[0433] Figures 40 to 44 A diagram for explaining an example of the update of the database 57. The player 82a places the placed game coin 831a in the placement area 41b. If the player 82b places the placed game coin 831b in the same placement area 41b, then as Figure 40As shown, in the RF control device 54, from the placement area 41b, as user IDs, the game coin IDs "C00001" to "C00005" of the placed game coins 831a and the game coin IDs "C10001" to "C10005" of the placed game coins 831b are read out, and the combination with the area ID "Area 2" of the placement area 41 is output to the management control device 56. In addition, from the game coin tray 12, the game coin IDs "C20001" to "C20100" are read out, and in the management control device 56, the combination with the area ID "Area T" of the game coin tray 12 is obtained.

[0434] As Figure 40 shown, at this time point, in the database 57, the game coin IDs "C00001" to "C00005" are associated with the user ID "P1", the game coin IDs "C10001" to "C10005" are associated with the user ID "P2", and the game coin IDs "C20001" to "C20100" are associated with the user ID "D".

[0435] If the game result is that both players 82a and 82b win, then as Figure 41 shown, first, the dealer makes a payment to either the placed game coins 831a or the placed game coins 831b. At this time, in the placement area 41b, in addition to the game coin IDs "C00001" to "C00005" of the placed game coins 831a and the game coin IDs "C10001" to "C10005" of the placed game coins 831b, the game coin IDs "C20001" to "C20005" of the paid game coins 832a are also read out, and the combination with the area ID "Area2" of the placement area 41 is output to the management control device 56.

[0436] At this stage, the management control device 56 still cannot determine whether the placed game coins 831a with the game coin IDs "C00001" to "C00005" of the paid game coins 832a have been paid, and whether the placed game coins 831b with the game coin IDs "C10001" to "C10005" have been paid. Therefore, the database 57 is not updated.

[0437] Next, if player 82a takes away the placed game coins 831a and the paid game coins 832a for the placed game coins from the placement area 41b, then as Figure 41As shown, in the placement area 41b, only the game coin IDs "C10001" to "C10005" of the remaining placed game coins 831b are read. Based on this change, the management control device 56 determines that the paid game coins 832a with the game coin IDs "C20001" to "C20005" read in the placement area 41b are paid to the placed game coins 831a with the game coin IDs "C00001" to "C00005", and rewrites the user ID associated with the game coin IDs "C20001" to "C20005" in the database 57 from "D" to "P1", that is, rewrites it to the user ID associated with the placed game coins 831a that are taken away from the placement area 41b together with the paid game coins 832a with the game coin IDs "C20001" to "C20005".

[0438] The dealer confirms whether the placed game coins 831a and the paid game coins 832a paid to the placed game coins are taken away from the placement area 41b. As Figure 43 shown, in the same placement area 41b, the paid game coins 832b are paid to the placed game coins 831b. In this way, from the placement area 41b, the game coin IDs "C10001" to "C10005" of the placed game coins 831b and the game coin IDs "C20006" to "C20010" of the paid game coins 832b are read, and they are recorded in the management control device 56 in combination with the area ID "Area2" of the placement area 41.

[0439] After that, if the player 82b takes away the placed game coins 831b and the paid game coins 832b, then as Figure 44 shown, no game coin ID can be read from the placement area 41b, and only the game coin IDs read from the game coin tray 12 are input into the management control device 56. Based on this change, the management control device 56 determines that the paid game coins 832b with the game coin IDs "C20006" to "C20010" are delivered to the same player as the player of the placed game coins with the game coin IDs "C10001" to "C10005", and updates the database 57 so that in the database 57, the user ID associated with the game coin IDs "C20006" to "C20010" is the same as the user ID associated with the game coin IDs "C10001" to "C10005".

[0440] As described above, according to the management system 170 of this example, it is detected that the placed game coins 831 and the paid game coins 832 are taken away from the placement area together, and the database 57 is updated so that the user ID of the paid game coins 832 is the same as the user ID of the placed game coins 831. Thus, even when the game coins 83 of multiple players are placed in the same placement area 41, by paying these players in order, it is possible to know which player the paid game coins 832 are paid to, update the database 57, and track the owner of the game coins.

[0441] (Eighth example)

[0442] Figure 45 A diagram showing the structure of the management system of the eighth example of the fourth embodiment. The management system 180 has the same structure as the management system 140 of the fourth example. However, in the management system 180, on the gaming table 4004, as placement areas, there are a P.P area 44, a draw area 45, and a B.P area 46. In addition, on the gaming table 4004, antennas 514, 515, and 516 are provided corresponding to the P.P area 44, the draw area 45, and the B.P area 46.

[0443] In each of these areas 44 to 46, it is divided according to each player's position within the area. When a player places in these areas 44 to 46, the placed game coins are placed at the position (division) corresponding to their respective player positions within these areas.

[0444] That is, the P.P area 44, the draw area 45, and the B.P area 46 are shared placement areas shared by multiple players. In Figure 45 the example, players 82a to 82C participate in the game, and players 82b and 82C among these players respectively place the placed game coins 831b and 831C in the draw area 45.

[0445] In this example case, for the shared placement areas 44 to 46, similar to the sixth or seventh example, it is possible to track the owner of the game coins 83. It should be noted that even when the management system 180 does not have the database 57, similar to the sixth example, it is still possible to track the owner of the game coins 83. Even when the management system 180 does not have a player determination system, for the shared placement areas, similar to the seventh example, it is also possible to track the owner of the game coins 83.

[0446] (Ninth example)

[0447] Figure 46A diagram showing the structure of the management system for the ninth example of the fourth embodiment. The management system 190 includes a player identification system. In this example, the tracking of the game currency 83 is performed without using the database 57. In addition, the gaming table 4004 is provided with payment areas 42a to 42e and antennas 512a to 512e corresponding to the payment areas. Further, the fixed information 3 of the RFID tag 2 of the game currency 83 stores information indicating the amount (value) of the game currency 83, and the variable information 4 stores the user ID of the owner.

[0448] It should be noted that in this example, the database 57 can be used. In this case, the game currency 83 stores a game currency ID, and the amount (value) of the game currency 83 and the user ID of the owner are stored in the database 57 in a manner associated with the game currency ID.

[0449] As Figure 47 shown, if the placed game currency 831a (5 game currencies with an amount of "100") of the player 82a and the placed game currency 831b (2 game currencies with an amount of "1000") of the player 82b are placed in the placement area 41b, then from this placement area 41b, 5 game currencies 83 with an amount of "100" and a user ID of "P1" are read, and 2 game currencies 83 with an amount of "1000" and a user ID of "P2" are read, and they are output to the management control device 56 together with the "Area2" which is the area ID of the placement area 41.

[0450] For each placement area 41, the management control device 56 calculates the total value of the placed game currency for each player, thereby detecting the placement amount of each player. In Figure 47 it, the management control device 56 detects that the placement amount of the user ID "P1" is "500", and the placement amount of the user ID "P2" is "2000".

[0451] In the case where the game results in both players 82a and 82b winning, the dealer pays (repays) the placed game currency 831a and 831b in sequence. As Figure 48 shown, first, when paying the payment game currency 832a for the placed game currency 831a, the dealer places the payment game currency 832a in the payment area 42b.

[0452] At this time, the RF control device 54 reads the game currency 83 in the payment area 42b, and reads that there are 5 game currencies 83 with an amount of "100", and outputs these situations to the management control device 56. The management control device 56 calculates the total amount of the payment game currency 832a read in the payment area 42b, thereby detecting the payment amount.

[0453] The management control device 56 compares the payment amount of the payment game coins 832a and the placement amount of each player in the placement area 41b, and determines the player whose placement amount is consistent with the payment amount. In Figure 48 five payment game coins 832a with an amount of "100" are read from the payment area 42b, and the payment amount is detected as "500". The management control device 56 determines that the payment amount "500" is consistent with the placement amount "500" of the placement game coins 831a of the user ID "P1", and rewrites the user ID of the payment game coins 832a to "P1".

[0454] After that, if the player 82a takes away the payment game coins 832a and the placement game coins 831a, then as Figure 49 shown, the placement game coins 831b of the player 82b remain in the placement area 41b. If the dealer places the payment game coins 832b to be paid out for the placement game coins 831b in the payment area 42b, the management control device 56 calculates the total amount of the payment game coins 832b to detect the payment amount of the payment game coins 832b.

[0455] The management control device 56 compares the payment amount of the payment game coins 832b and the placement amount of each player in the placement area 41b, and determines the player whose placement amount is consistent with the payment amount. In Figure 49 two payment game coins 832b with an amount of "1000" are read from the payment area 42b, and the payment amount is detected as "2000". The management control device 56 determines that the payment amount "2000" is consistent with the placement amount "2000" of the placement game coins 831b of the user ID "P2", and rewrites the user ID of the payment game coins 832b to "P2".

[0456] As described above, in the management control system 190 of this example, even when multiple players make placements in the same placement area 41, when these placement amounts are different, based on the placement amount and the payment amount of the payment game coins, it is determined to which player the payment game coins are paid.

[0457] (Tenth example)

[0458] In the first to ninth examples above, when the player 82 is a non-member who is not registered as a member, such a non-member does not have a user ID attached, so the player 82 cannot be determined by the player determination system. In addition, as described above, for the game coins 83 owned by non-members, the RFID tag 2 or the database 57 does not store a valid user ID, so the user ID is recorded as "Unknown".

[0459] When paying out 832 game coins to non - member players, the management system records the user ID of the player who receives the 832 game coins as "Unknown". When retrieving the 831 placed game coins from non - member players, the user ID of the player who placed the 831 game coins is recorded as "D".

[0460] When members and non - members place items in the same placement area 41, if both players win the game, the dealer can make payments according to rules such as usually starting with non - members or usually starting with members.

[0461] For example, when applying the rule of usually starting with non - members for payment, the management system changes the user ID of the first - paid 832 game coins to "Unknown", and for the later - paid 832 game coins, using the above example, changes it to the user ID of the player who is a member.

[0462] In addition, for example, when applying the rule of usually starting with members for payment, the management system changes the user ID of the first - paid 832 game coins to the user ID determined according to the 831 placed game coins, and for the later - paid 832 game coins, changes the user ID to "Unknown".

[0463] It should be noted that when the dealer determines the player using the card authentication system, the membership card 81 is scanned in person, so it is possible to know which player is a member. However, when using the face recognition system to determine the player, it is impossible to know which player is a member. Among them, as the recognition result of the face recognition system, visual information indicating the position of the player or the placement area of the user ID recognized can be shown to the dealer through a monitor or the like.

[0464] (The eleventh example)

[0465] Figure 50 A diagram showing an example of the placement area in the eleventh example of the fourth embodiment. In this example, the placement area 41 for each player position is divided into a placement area 411 for members and a placement area 412 for non - members, and the antennas are also divided into an antenna 5111 for members and an antenna 5112 for non - members.

[0466] The management control device 56 controls the RF control device 54, and for the 831 placed game coins placed in the member - only placement area 411, changes the user ID of the 83 game coins as in the first to ninth examples above. For the 831 placed game coins placed in the non - member - only placement area 412, the user ID of the 832 game coins paid for the placed game coins is all changed to "Unknown".

[0467] According to this example, there is no situation where the game coins 83 with the user ID attached to the player stored in the game coins themselves or in the database 57 and the game coins 83 (with the user ID "Unknown") without the user ID attached to the player stored in the game coins themselves or in the database 57 are mixed and read, and the game coins 83 with the user ID attached to the player stored in the game coins themselves or in the database 57 can be effectively tracked.

[0468] It should be noted that in this example, instead of the antennas 5111 and 5112, one antenna can be set across the member placement area 411 and the non-member placement area 412. In this case, when game coins 83 are placed in the member placement area 411 and the non-member placement area 412 respectively, the dealer can identify which game coin 831 placed is for a member and which is for a non-member.

[0469] Moreover, in the case of making payments for any placed game coin 831, the dealer can make payments according to the operation rule of making payments to the member game coins 831 first. Thus, the management system can determine that the payment game coin 832 paid first is the game coin for paying a member. It should be noted that the dealer can also make payments according to the operation rule of making payments to the non-member game coins 831 first. In this case, the management system can determine that the payment game coin 832 paid first is the game coin for paying a non-member.

[0470] Figs. 51a and 51b are diagrams showing other examples of the placement areas in the eleventh example of the fourth embodiment. In this example, the placement area 41 at each player position is selectively set as the member placement area 41 shown in Fig. 51a or the non-member placement area 41 shown in Fig. 51b.

[0471] Near each placement area 41, a display unit 413 is provided, and the display unit 413 variably displays whether the placement area 41 is set as a member area or a non-member area. The display unit 413 is provided under the fabric of the gaming table 4004, and the information can be set to be visually confirmed by the player through the fabric.

[0472] It should be noted that the structure for visually displaying that each placement area 41 is set as either a member or a non-member is not limited to the display unit 413 embedded under the fabric of the gaming table 4004. For example, it can be displayed through a monitor provided on the gaming table 4004 in a manner visible to the player that each placement area 41 is set as either a member or a non-member.

[0473] The management control device 56 controls the RF control device 54. When the placement area 41 is set for members, for the placed game tokens 831 placed in this area, as shown in the first to ninth examples above, the user ID of the game token 83 is rewritten. When the placement area 41 is set for non - members, for the placed game tokens 831 placed in this area, the user IDs of all the payment game tokens 832 paid to this game token are rewritten to "Unknown".

[0474] In this example, there is no situation where game tokens 83 with the user ID attached to the player stored in the game token itself or the database 57 and game tokens 83 (with the user ID "Unknown") without the user ID attached to the player stored in the game token itself or the database 57 are mixed and read, and the game tokens 83 with the user ID attached to the player stored in the game token itself or the database 57 can be effectively tracked.

[0475] (Twelfth example)

[0476] In the first to ninth examples above, when game tokens 83 are exchanged between the dealer and the player on the gaming table 4003, the owner of the game token 83 can also be tracked. In this case, the management system has a progress status determination mechanism for determining the progress status of the game (i.e., any one of being placed, in - game, and settled). As the progress status determination mechanism involved, the card - issuing device 4003 can be used, or any other mechanism can be used.

[0477] In the management system of this example, during placement, the management control device 56 controls the RF control device 54 to make each antenna read periodically at a specified time interval. During placement, when the management control device 56 reads a game token 83 with the user ID "D" in any one placement area 41 or any one payment area 42 (hereinafter referred to as "the reading area of the gaming table 4004"), and when it reads a game token 83 with the user ID attached to the member in the game token tray 12, it determines that the game tokens 83 are exchanged.

[0478] The reason is that in the operation of a certain card game, during placement, except for exchange, it is impossible to move the game token 83 from the game token tray 1 to the gaming table 4003, and the game tokens 83 of the player on the gaming table 4003 cannot be moved to the game token tray 12 either. It should be noted that when the progress status of the game is "in - game", such a movement of the game token 83 is cheating behavior. Therefore, when the management control device 56 detects the above - mentioned movement of the game token 83 during the game, it can output an alarm.

[0479] During placement, when the management control device 56 reads from the game coin tray 12 a game coin 83 whose user ID is the user ID attached to a member or "Unknown", it is determined that the game coin 83 is a game coin 83 (pre-exchange game coin) taken out by a player to the gaming table 4004 for exchanging game coins.

[0480] Specifically, when the user ID is stored in the game coin 83 itself, when the management control device 56 reads from the game coin tray 12 during placement the user ID attached to a member or "Unknown", it is determined as an exchange. When the user ID is stored in the database 57, when the number of game coins 83 read from the game coin tray 12 during placement decreases, it is determined that an exchange is in progress. Or, when the user ID is stored in the database 57, when the number of game coins 83 read from the game coin tray during placement increases, it can be determined that an exchange is in progress.

[0481] In addition, during placement, when the management control device 56 reads from the reading area of the gaming table 4004 a game coin 83 whose user ID is "D" indicating that it is held by the casino or the dealer, the game coin 83 is determined as a game coin 83 (post-exchange game coin) given to the player corresponding to the pre-exchange game coin.

[0482] Specifically, when the user ID is stored in the game coin 83 itself, when the management control device 56 reads from the reading area of the gaming table 4004 during placement the user ID "D", it is determined as an exchange. When the user ID is stored in the database 57, the management control device 56 periodically reads the reading area of the gaming table 4004 during placement, and for each reading, by referring to the database 57, it is determined that the game coin 83 with the user ID "D" is read from the reading area of the gaming table 4004.

[0483] The management control device 56 rewrites the user ID of the pre-exchange game coin to "D" indicating the casino or the dealer, and rewrites the user ID of the post-exchange game coin to the user ID of the pre-exchange game coin. Specifically, when the user ID is stored in the RFID tag 2 of the game coin 83, the management control device 56 controls the RF control device 54 to rewrite the user IDs stored in the corresponding pre-exchange game coin and post-exchange game coin. When the user ID is stored in the database 57 associated with the game coin ID, the management control device 56 rewrites the user ID associated with the corresponding game coin ID in the database 57.

[0484] In addition, after the management control device 56 determines the pre-exchange game coin and the post-exchange game coin, it controls the RF control device 54 to change these user IDs (when the user ID is stored in the game coin 83), or can update the database 57 (when the user ID is stored in the database 57).

[0485] It should be noted that in the above-described embodiment, the membership card 81 is a magnetic card, and the card reader 53 is a magnetic card reader that reads information from the magnetic stripe of the membership card 81. As an alternative, an RFID tag can be embedded in the membership card 81, and the user ID can be recorded in the RFID tag. In this case, an RFID reader composed of an antenna and an RF control device 54 is used as the card reader 53. In addition, such an antenna can be provided at each player position. In this case, without the player personally handing over his or her membership card 81 to the dealer, it can be read at each player position. Information determining the player position is sent from each antenna to the RF control device 54 together with the user ID read from the membership card 81. Further, the antenna 511 provided in the placement area 41 and the RF control device 54 can be used as an RFID reader for reading the membership card 81. In this case, the antenna 511 can read the user ID by the player placing the membership card 81 in the placement area 41 at his or her player position.

One side of the table 6004 is the dealer position where the dealer is located (the position adjacent to the game coin tray 51 described later), and on the other side, a plurality of player positions where players play the game are provided. In Figure 53 the example, five player positions are provided on the lower side of the table 6004.

[0560] A game coin tray 51 for storing the game coins 83 held by the dealer is provided in the dealer position in a manner embedded in the table 6004. The game coin tray 51 is a double-layer type, and the upper layer can be removed to replenish or take out the game coins 83 in the lower layer.

[0561] An RFID tag 831 (see Figure 56 ) is embedded in the game coin 83. At least game coin identification information (hereinafter also referred to as "game coin ID") for uniquely identifying the game coin is stored in the RFID tag 831. Information indicating the value of the game coin can also be stored in the RFID tag 831.

[0562] Placement areas 41a to 41e (hereinafter collectively referred to as "placement area 41") are provided at each player position for a player playing the game at that player position to place the game coin 83 on a placement object for placement. The placement area 41 is drawn on the upper surface of the table 6004. Adjacent placement areas 41 are separated by one or two lines. The distance between adjacent placement areas 41 is relatively close, and at the closest point, the distance is 0 to 15 cm, for example, smaller than the diameter of the game coin 83.

[0563] Although the illustration is omitted, in the placement areas 41a to 41e at each player position, a P.P area for placing a PAIR of the P player's hand, a B.P area for placing a PAIR of the B player's hand, a draw area for placing the same points of the P player's hand and the B player's hand, a P area for placing a win of the P player's hand, and a B area for placing a win of the B player's hand are provided adjacent to each other in a non-overlapping manner. Hereinafter, these P.P area, B.P area, draw area, P area, and B area will be respectively referred to as "placement target areas". Adjacent placement target areas are separated by one or two lines. Alternatively, no line may be provided between adjacent placement target areas, and the adjacent placement target areas may be distinguished by coating them with different colors from each other, or the placement target areas may be coated with a color different from the background to distinguish each placement target area. The distance between adjacent placement target areas is relatively close or at the closest, and the distance is 0 to 10 cm, for example, smaller than the diameter of the game coin 83.

[0564] At each player position, there are provided payment areas 42a to 42e (hereinafter, collectively referred to as "payment area 42"), which are used for reading game coins when paying game coins 83 from the dealer to the player. The payment area 42 is drawn on the upper surface of the table 6004. Adjacent payment areas 42 are separated by one or two lines. Alternatively, no line may be provided between adjacent payment areas 42, and the adjacent payment areas 42 may be distinguished by coating them with different colors from each other, or the payment area 42 may be coated with a color different from the background to distinguish each payment area 42. In addition, adjacent payment areas 42 and placement areas 41 are separated by one or two lines. Alternatively, no line is provided between adjacent payment areas 42 and placement areas 41, and the adjacent payment areas 42 and placement areas 41 are distinguished by coating them with different colors from each other, or the payment area 42 and the placement area 41 are coated with a color different from the background therebetween to distinguish each payment area 42 and placement area 41. The distance between adjacent payment areas 42 is relatively close, and at the closest, the distance is 0 to 10 cm, for example, smaller than the diameter of the game coin 83. In addition, the distance between the payment area 42 and the placement area 41 at each player position is relatively close or at the closest, and the distance is 0 to 15 cm, for example, smaller than the diameter of the game coin 83.

[0565] In the placement areas 41a to 41e, there are provided reading antennas 511a to 511e (hereinafter, collectively referred to as "reading antenna 511") for reading the RFID tags 831 embedded in the game coins 83 respectively placed in the placement areas 41a to 41e. In the payment areas 42a to 42e, there are provided reading antennas 521a to 521e (hereinafter, collectively referred to as "reading antenna 521") for reading the RFID tags 831 embedded in the game coins 83 respectively placed in the payment areas 42a to 42e. In the game coin tray 51, there is provided a reading antenna 531 for reading the RFID tag 831 embedded in the game coin 83 stored in the game coin tray 51. It should be noted that, as described above, the game coin tray 51 is a double-layer type, and the reading antenna 531 can be provided, for example, inside the upper tray.

[0566] In addition, in the placement areas 41a to 41e, there are provided reading restriction antennas 512a to 512e (hereinafter, collectively referred to as "reading restriction antenna 512") for restricting or preventing the RFID tags 831 embedded in the game coins 83 respectively placed in the placement areas 41a to 41e from being read by the reading antennas in other areas. In the payment areas 42a to 42e, there are provided reading restriction antennas 522a to 522e (hereinafter, collectively referred to as "reading restriction antenna 522") for restricting or preventing the RFID tags 831 embedded in the game coins 83 respectively placed in the payment areas 42a to 42e from being read by the reading antennas in other areas. In the game coin tray 51, there is provided a reading restriction antenna 532 for restricting or preventing the RFID tag 831 embedded in the game coin 83 stored in the game coin tray 51 from being read by the reading antennas in other areas.

[0567] It should be noted that, in the present embodiment, the reading antenna 511 and the reading restriction antenna 512 in the placement area 41 are in the shape along the outer edge of the placement area 41, the reading antenna 521 and the reading restriction antenna 522 in the payment area 42 are in the shape along the outer edge of the payment area 42, and the reading antenna 531 and the reading restriction antenna 532 in the game coin tray 51 are in the shape along the outer edge of the game coin tray 51. However, the shape of the antenna is not limited to this. In addition, in the Figure 53 example, the reading restriction antenna is provided inside the reading antenna. However, the positional relationship between the reading antenna and the reading restriction antenna is not limited to this. The reading restriction antenna can be provided outside the reading antenna, and in a top view, the reading restriction antenna and the reading antenna can intersect. In addition, multiple reading restriction antennas can be provided relative to one reading antenna. Conversely, one reading restriction antenna can be provided relative to multiple reading antennas.

[0568] On the table 6004, there is a card dealing device 58. The card dealing device 58 stores multiple decks of cards. The dealer 91 can draw cards one by one from the card dealing device 58. The card dealing device 58 has the function of reading the suit and face value of the drawn cards. Based on at least the face value of the drawn cards, the card dealing device 58 determines the game result according to the rules of a certain card game. The card dealing device 58 displays the determined game result through a lamp or the like, and outputs the data representing the game result to the outside. In this way, the card dealing device 58 functions as a game result determination device.

[0569] On the table 6004, there is also a camera 52 and a card reader 53 installed. The camera 52 takes pictures of the faces of the players 82 playing the game at the player positions and the game coins 83 on the table 6004. It should be noted that the camera for taking pictures of the players' faces and the camera for taking pictures of the game coins 83 on the table 6004 can be set separately.

[0570] The card reader 53 reads the information stored in the membership card 81 by scanning the membership card 81 held by the registered player (member). An RFID tag is built into the membership card 81, and at least the user ID assigned to the player is stored in the RFID tag. The card reader 53 has an operation part (not shown) for the dealer 91 to specify the player position. When the dealer 91 scans the membership card 81 with the card reader 53, the dealer 91 specifies the player position. Thereby, a combination of the player position and the user ID is output from the card reader 53. In addition, the card reader 53 has a cancellation operation part (not shown). When the player 82 leaves the table, the dealer 91 specifies the player position and operates the cancellation operation part. Thereby, the player position and the cancellation instruction are output from the card reader 53.

[0571] On the above-mentioned table 6004, when the player 81 plays a certain card game, the player 82 first sits at a certain player position on the table 6004, and then hands his membership card 81 to the dealer 91. The dealer 91 scans the membership card 81 with the card reader 53. The player 81 places the game coin 83 in any of the placement target areas in the P area, B area, draw area, P.P area, and B.P area of the placement area 41 provided at his own player position.

[0572] When the placement of all the players 82 is completed, the dealer 91 stops the placement and draws cards one by one from the card dealing device 58. In a certain card game, according to the order of P player's hand, B player's hand, P player's hand, B player's hand, 4 cards are drawn first. At this time, if P.P is not established, the placed game coins in P.P are recovered by the dealer 91 to the game coin tray 51. In addition, at this time, if B.P is not established, the placed game coins in B.P are recovered by the dealer 91 to the game coin tray 51.

[0573] The dealer 91 draws cards after the 5th card as needed according to the rules of a certain card game. When finally determining the game result, the dealer 91, based on the game result, retrieves the game tokens 83 placed by the losing players into the game token tray 51, and then pays out the game tokens 83 from the game token tray 51 to the winning players for the game tokens 83 they placed. At the time of this payment, the dealer 91 first temporarily places the game tokens in the payment area 42 at the position of the player where the payable placed game tokens 83 are located, and then places the paid game tokens 83 beside the placed game tokens 83. The winning player receives the game tokens (paid game tokens) placed beside the placed game tokens 83 in this way as placed game tokens. When the dealer 91 starts the next game (i.e., when starting to place for the next game), the dealer 91 presses the game start button provided on the card dispensing device 58.

[0574] Figure 54 A block diagram showing the structure of the game table reading system according to the sixth embodiment of the present invention. The game table reading system 100 includes a card dispensing device 58, a player determination system 55, a reading control device 561, a reading restriction control device 562, a management control device 56, a database 57, reading antennas 511, 521, 531, and reading restriction antennas 512, 522, 532.

[0575] The player determination system 55 includes a camera 52, a card reader 53, and a face recognition device 502. The face recognition device 502 authenticates the player based on the image of the player's face captured by the camera 52. The face recognition device 502 can perform face authentication using machine learning techniques. The face recognition device 502 also determines the position of the authenticated player, that is, the player position of the authenticated player, based on the position of the player's face. In addition, in the present embodiment, the player can be determined by a face authentication system including the camera 52 and the face recognition device 502, and the membership card 81 can be read by the card reader 53 to determine the player, but the player can also be determined without using any of the above methods.

[0576] The card dispensing device 58 outputs the progress status of the game (i.e., during the transaction, between the end of the game and the start of the next game, placing, etc.) to the management control device 56 based on button operations or the face value of the drawn cards read, and outputs the game result (win of the P player's hand, win of the B player's hand, draw, PAIR of the P player's hand, PAIR of the B player's hand, etc.) to the management control device 56.

[0577] The reading control device 561 reads the RFID tag 831 in the reading area corresponding to the reading antenna by controlling the reading antennas 511, 521, and 531. The reading restriction control device 562 controls the reading restriction antennas 521, 522, and 523 so that the RFID tags in the reading area corresponding to the reading restriction antenna are not read by the reading antennas corresponding to other reading areas.

[0578] The management control device 56 controls the reading control device 561 and the reading restriction control device 562 to read the RFID tags in multiple reading areas in sequence according to the progress of the game from the card issuing device 58 and referring to the information stored in the database 57 as needed. The management control device 56 updates the database 57 by storing the information read from the RFID tag by the reading antenna in association with the player determined by the player determination system 555 in the database 57. Antenna identification information (antenna ID) for uniquely identifying the reading antenna is attached to each of the reading antennas 511, 521, and 531.

[0579] The reading control device 561 packs and sends the information read by the reading antennas 511, 521, and 531 and the antenna ID of the reading antenna to the management control device 56. It should be noted that the reading control device 561 can be provided for each reading antenna. In this case, for each reading control device 561, instead of the antenna ID, the reader identification information (reader ID) for uniquely identifying the reading control device 561 can be sent to the management control device 56.

[0580] As Figure 54 shown, the reading antennas 511, 521, and 531 are set as a partially open ring in the corresponding reading area, and both ends of the open end are connected to the reading control device 561. The reading control device 561 forms an electromagnetic field in the reading area by passing an electric current through the reading antenna to read the RFID tag.

[0581] One end and the other end of the reading antennas 511, 521, and 531 are respectively connected to the reading control device 561 via switches (not shown). The reading control device 561 controls the opening and closing of the switches. Specifically, for the reading antennas 511, 521, and 531 in the reading areas where reading is not performed, the reading control device 561 opens the switches, thereby opening the rings of the reading antennas 511, 521, and 531, and making the induced current not flow through the reading antennas 511, 521, and 531 that do not perform reading by the electromagnetic field generated by the reading antennas 511, 521, and 531 in adjacent other reading areas.

[0582] The reading restriction antennas 512, 522, 532 have a loop around the corresponding reading area, and switches 521s, 522s, 532s with a closed or open loop. The reading restriction control device 562 opens and closes the switches 521s, 522s, 532s. The reading restriction antennas 512, 522, 532 function to restrict reading when the switches 521s, 522s, 532s are closed to form a closed loop (short circuit), and do not restrict reading when the switches 521s, 522s, 532s are opened to form an open loop.

[0583] Figure 55 It is a cross-section of the placement areas 41b and 41c as the reading areas. Below the surface 6004a of the table 6004, a substrate 401 for disposing the reading antennas 511, 521 and a substrate 402 for disposing the reading restriction antennas 512, 522 are overlapped and provided. In the present embodiment, the substrate 401 is provided below the substrate 402, but the setting order can be appropriately changed. In addition, the vertical distance between the reading antennas 511, 521 and the reading restriction antennas 521, 522 is appropriately set based on the intensity of the electromagnetic wave, the shapes of the reading antennas 511, 521 and the reading restriction antennas 521, 522, etc. Also, the reading antennas 511, 521 and the reading restriction antennas 512, 522 can be provided on the same substrate.

[0584] In the case of reading the reading area 41b, in the reading area 41c adjacent to the reading area 41b, the switch 512s of the reading restriction antenna 512c is closed to form a closed loop. Through the reading restriction antenna 512c, the induced power generated by the electromagnetic field formed by the reading antenna 511b in the adjacent reading area 41b is used to form a restricting (obstructing) electromagnetic field, and the electromagnetic field of the reading antenna 511b is shaped by this restricting electromagnetic field to restrict (obstruct) the reading of the game coin 83c placed in the adjacent reading area 41c by the reading antenna 511b. The game coin 83b placed in the reading area 41b corresponding to the energized reading antenna 41b is read by the reading antenna 41b.

[0585] Figure 55 The intensity distribution 5111b of the electromagnetic field for reading in the placement area 41b generated by the reading antenna 511b and the intensity distribution 5111c of the electromagnetic field generated by the reading restriction antenna 511c during the reading of the placement area 41b are shown. In addition, Figure 55 The intensity distribution 5112b when the electromagnetic field generated by the reading antenna 511b is weakened by the electromagnetic field generated by the reading restriction antenna 512c in the adjacent placement area 41c, and the intensity distribution 5112c when the electromagnetic field generated by the reading antenna 511c is weakened by the electromagnetic field generated by the reading restriction antenna 512b in the adjacent placement area 41c are shown.

[0586] As shown Figure 55 in the figure, when an electromagnetic field having an intensity distribution 5111b for reading the RFID tag 831 of the game coin 83b placed in the placement area 41b is generated by the reading antenna 511b, by closing the switch of the reading restriction antenna 512c of the adjacent placement area 41c, an induced current flows through the reading restriction antenna 512, whereby an electromagnetic field for reading interference is generated. As a result, the electromagnetic field of the intensity distribution 5111b generated by the reading antenna 511b is shaped into an electromagnetic field such as the intensity distribution 5112b, which is small enough and flattened in the adjacent placement area 41c. Thereby, the RFID tag 831 of the game coin 83c in the placement area 41c can be prevented from being read by the reading antenna 511b.

[0587] In addition, an aluminum tape is attached to the substrate 402 as a shielding member or a blocking means for shielding electromagnetic waves from an adjacent reading area. Note that the shielding member may be in a form other than a tape, for example, it may be a plate, a film, a sheet, a coating film, a foil, etc. In addition, the material of the shielding member may be other than aluminum, such as silver, gold, copper, nickel, etc., or may be a material containing aluminum, silver, gold, copper, nickel. And the shielding member may be a mesh. In addition to the reading restriction antennas 512b and 512c, the reading of the reading antennas in adjacent reading areas can also be restricted by this shielding member.

[0588] Note that in the example of Figure 55 , the shielding member may be provided on the substrate 402 for disposing the reading restriction antennas 513 and 512c, but the shielding member may also be provided on the substrate 401 for disposing the reading antennas 511 and 521. Or, the shielding member may be provided on the surface of the substrate 402 opposite to the reading restriction antennas 512b and 512c, and may be provided on the surface of the substrate 401 opposite to the reading antennas 511b and 511c. Or, the shielding member may be provided on a plane different from the substrate 401 and the substrate 402.

[0589] The game table reading system 100 of the present embodiment uses the database 57 to manage the game coins 83. The database 57 stores the information of the RFID tag built in the game coin 83 in association with prescribed association information. The management control device 56 updates the database 57 based on the information of the RFID tag read by the reading antennas 511, 521, 531 and the relationship between the placement areas 41, 42 and the game coin tray 51 as the reading areas for reading the RFID tag. In this way, the management control device 56 updates the database 57 for managing the game coins 83 according to the information of the RFID tags of the game coins 83 read in each reading area of the game table 6004.

[0590] Hereinafter, the management of the game coins 83 by the database 57 will be described.Figure 56 This is a diagram showing the data structure of game tokens 83 and the database 57. As described above, the game token 83 is built-in with an RFID tag 831. The RFID tag 831 stores the game token ID 573. The database 57 has two types of tables, including a game token management table 571 for managing the game tokens 83 and a user management table 572 for managing users.

[0591] In the game token management table 571, for each game token 83, the game token ID 573 of the game token 83, the value information 574 of the game token 83, the user identification information (user ID) 575 for uniquely identifying the user who holds the game token, and the location information 576 indicating the location of the game token 83 are associated as association information. It should be noted that although the value information 574 does not change for the game token ID 573, the user ID 575 and the location information 576 associated with the game token ID 573 will change when the game token 83 is used in the casino. Therefore, in the database 57, for the game token ID 573, in addition to the latest user ID and location information, fixed past user ID and location information can be stored, or only the latest user ID and location information can be stored.

[0592] In the user management table 572, for each user, for the user ID 575 of the user, the value information 574 of the game tokens held by the user, the placement information 577 indicating the history of the user's placement in the game, and the location information 576 indicating the location of the user are associated as association information. The value information 574, the placement information 577, and the location information 576 associated with the user ID 575 will change when the game token 83 is used in the casino. Therefore, in the database 57, for the user ID 575, in addition to the latest value information, placement information, and location information, fixed past value information, placement information, and location information can be stored, or only the latest value information, placement information, and location information can be stored.

[0593] The gaming table reading system 100 updates the game token management table 571 and the user management table 572 of the database 57 based on the information of the RFID tag 831 read by the reading antenna to manage the game tokens 83. The specific method of using the database 57 to manage the game tokens 83 can adopt any method described in the above embodiments. Hereinafter, the management of the game tokens 83 in this embodiment will be described, including descriptions that may be repeated from the above explanations.

[0594] It should be noted that in the following description, the management control device 56 updates the database 57. However, the management control device 56 updates the database based on the information of the RFID tag 831 read by each reading antenna and the game status when the information is read. In the present embodiment, the management control device 56 grasps the game status by obtaining information on the game status (in-game, placed, settled, paused, etc.) from the card issuing device 58.

[0595] First, the management control device 56 updates the game coin management table 571 of the database 57 in such a way that the game coin ID of the game coin 83 paid to the user who wins the game is associated with the user ID of the user who wins the game. In addition, the management control device 56 updates the game coin management table 571 of the database 57 in such a way that the game coin ID of the game coin 83 placed by the user who loses the game is associated with the user ID assigned by the dealer. Thus, even if the owner of the game coin 83 changes due to the use of the game coin 83 in the game, the game coins held by each user can be determined by referring to the database 57.

[0596] In addition, the management control device 56 updates the database 57 in such a way that the game coin ID of the game coin 83 read in the payment area 42 is associated with the user ID of the user playing the game at the player position corresponding to the payment area 42. According to the above embodiment, the user ID of the user playing the game at each player position can be determined by the player determination system 55.

[0597] Specifically, in the game coin management table 571 of the database 57, the management control device 56 records the user ID of the user at the player position in the payment area 42 for the record of the game coin ID of the game coin 83 read in the payment area 42. By updating the database 57 in this way, the situation where the owner changes from the dealer to the user due to payment can be reflected in the database 57.

[0598] In addition, in the user management table 57 of the database 57, the management control device 56 updates the user management table 572 by adding the value of the game coin 83 paid to the user who wins the game to the value information 574 associated with the user ID 575 of the user who wins the game, and subtracting the value of the game coin 83 recovered from the user who loses the game from the value information 574 associated with the user ID 575 of the user who loses the game. By updating the database 57 in this way, the value of the game coin 83 held by each user, that is, the holding amount, can be managed in the database 57.

[0599] In addition, when the game coin ID of the paid game coin 83 is read in the payment area 42, the management control device 56 updates the database 57 in such a way that the game coin ID of the paid game coin 83 is associated with the user ID associated with the game coin 83 placed in the placement area 41 corresponding to the payment area 42.

[0600] Alternatively, when the game coin ID of the paid game coin 83 is read in the placement area 41, the management control device 56 updates the database 57 in such a way that the game coin ID of the paid game coin 83 is associated with the user ID associated with the game coin 83 placed in the placement area 41. Thus, the database 57 can be updated in such a way that the owner of the placed game coin 83 is the same as the owner of the game coin 83 for which the placed game coin 83 is paid.

[0601] In addition, when all the player positions are occupied and there are players waiting to place (i.e., when multiple players place at one player position), the management control device 56 manages the game coin 83 as follows. That is, when the player identification system 55 can identify the user IDs of both of the two users who are simultaneously at the same player position, the management control device 56 manages the game coin 83 for each user in the same way as described above. When the player identification system 55 can identify the user ID of one of the two users who are simultaneously playing at the same player position but cannot identify the identification information of the other user, the dealer makes a payment according to the operation rule of making a payment to the player whose user ID has been identified first. The management control device 56 updates the database 57 in such a way that the game coin ID of the game coin 83 that is paid first to this player position is associated with the user ID identified by the player identification system 55. The management control device 56 associates the game coin ID of the game coin 83 that is paid later with "unknown" as the user ID.

[0602] The reading antenna and the reading control device 561 for reading the RFID tag 831 built into the game coin 83 can be installed at various positions in the casino facility. In this case, the reading control device 561 can be installed at various positions in the casino facility, and the management control device 56 can communicate with these multiple reading control devices 561. As described above, the information of the RFID tag 831 read by the reading antenna can be sent from the reading control device 561 to the management control device 56 together with the antenna ID of the reading antenna or the reader ID of the reading control device 561. The management control device 56 has a table associated with the location information (location information, such as the counter number, table number, game coin tray number, entrance / exit number, etc. used to identify the counter, table, game coin tray, entrance / exit, etc.) of the reading antenna corresponding to each antenna ID or each reader ID.

[0603] If the management control device 56 receives the read game coin ID and the antenna ID (or reader ID) from the reading control device 561, it updates the location information 474 associated with the game coin ID in the game coin management table 571 of the database 57 according to this information. In addition, the management control device 56 also updates the location information 576 related to the theory of the game coin ID in the user management table 572.

[0604] Thus, by referring to the database 57, it is possible to know where each game coin 83 is located or where each user is located. In addition, in the game coin management table 571 and the user management table 572, by also storing the past information as the location information, the movement history of the game coin 83 and the user can be known.

[0605] In addition, the management control device 56 obtains the information of the user ID of the user playing the game at each player position from the player determination system 55. And if the game coin 83 is placed in the placement area 41 for placement, it obtains the game coin ID as the information of the RFID tag from the reading antenna 511 at each player position. The management control device 56 uses this user ID and game coin ID to update the user management table 572 of the database 57. Specifically, the management control device 56 refers to the game coin management table 571, obtains the value information 574 of the obtained game coin ID 573, and adds the value of the value information 574 to the placement information of the obtained user ID in the user management table 572.

[0606] In this way, the management control device 56 updates the database 57 in such a way that the value of the game coin 83 read by the reading antenna 511 in the placement area 41 is added to the placement information 577 associated with the user ID 575 of the user determined at the player position corresponding to the reading antenna 511. By updating the database 57 in this way, the value of the game coin 83 placed by each user, that is, the placement amount, can be managed in the database 57. It should be noted that the placement amount can also be managed as the corresponding reward points.

[0607] The information stored in the RFID tag 831 of the game coin 83, namely the game coin ID 573, is used for determining the authenticity of the game coin 83. When the management control device 56 reads the information of the RFID tag 831 by the reading antenna, it compares this information in the database 57. If the information does not exist in the database 57, that is, when the comparison is unsuccessful, it determines that the game coin 83 is defective or improper. When the management control device 56 determines that the game coin 83 is defective or improper, it outputs a warning. Thus, when an improper game coin 83 is used on the gaming table 6004, a warning can be output. The output warning can be output in a visually or audibly perceivable manner in a timely manner (i.e., at the moment of determining it as defective or improper), or the information on the situation (table number, date, time, etc.) when the impropriety or defect occurs can also be recorded in the recording device.

[0608] Figure 57 FIG. is a diagram showing another example of the reading antenna and the reading restriction antenna. In this example, a reading antenna is provided for each player position and each placement object, that is, for each side placement of P, B, draw, PAIR, etc. As Figure 57 shown, each placement area 41 has a plurality of placement object areas, and the plurality of placement object areas include a P area 411 provided adjacent to each player position, a B area 412, a draw area 413 as a side placement area, a P.P area 414, and a B.P area 415.

[0609] A reading antenna and a reading restriction antenna are provided in the placement object area that serves as the reading area respectively, whereby each placement object area can be distinguished for reading. That is, a reading antenna 5111 and a reading restriction antenna 5112 are provided in the P area 411, a reading antenna 5121 and a reading restriction antenna 5122 are provided in the B area 412, a reading antenna 5131 and a reading restriction antenna 5132 are provided in the draw area 413, a reading antenna 5141 and a reading restriction antenna 5142 are provided in the P.P area 414, and a reading antenna 5151 and a reading restriction antenna 5152 are provided in the B.P area 415.

[0610] In this way, by using each placement object area at each player position as a separate reading area and providing a reading antenna for each of them, it is possible to determine on which placement object the player placed the game coin 83 at each player position. In this way, in this example, as Figure 57As shown, even if multiple reading areas are densely arranged, the amusement table reading system 100 can separately read the RFID tags 831 of each of these reading areas. The management control device 56 can determine which player at which player position has won the game, that is, to which player position payment should be made, based on information on the game results of the card issuing device 58 and information on the placed objects obtained from each player position. When the judgment result does not match the actual payment, the management control device 56 can detect this mismatch and output a warning.

[0611] Figure 58 It is a diagram showing other examples of the reading restriction antenna. In Figure 58 only the placement areas 41b, 41c, 41d and the corresponding payment areas 42b, 42c, 42d are shown. In this example, a plurality of reading restriction antennas are provided in one placement area as a reading area. These multiple reading restriction antennas shape the electromagnetic fields generated by the reading antennas of the adjacent multiple other reading areas respectively.

[0612] Specifically, for example, in the placement area 41c as a reading area, in addition to the reading antenna 511c that reads the entire placement area 41c, three reading restriction antennas 512c1, 512c2, and 512c3 are also provided. The reading restriction antenna 512c1 is set so that the reading antenna 511d of the adjacent placement area 41d on the right does not read the RFID tag 831 of the game coin 83 placed in the placement area 41c. The reading restriction antenna 512c2 is set so that the reading antenna 511b of the adjacent placement area 41b on the left does not read the RFID tag 831 of the game coin 83 placed in the placement area 41c. The reading restriction antenna 512c3 is set so that the reading antenna 521c of the adjacent payment area 42c on the upper side does not read the RFID tag 831 of the game coin 83 placed in the placement area 41c.

[0613] When the reading control device 561 controls the reading antenna 511d to read the placement area 41d, the reading restriction control device 56 closes the switch of the reading restriction antenna 512c1 in the placement area 41c, so that the reading restriction antenna 512c1 generates an electromagnetic wave for preventing the reading antenna 511d from reading the RFID tag 831 in the placement area 41c. When the reading control device 561 controls the reading antenna 511b to read the placement area 41b, the reading restriction control device 562 closes the switch of the reading restriction antenna 512c2 in the placement area 41c, so that the reading restriction antenna 512c2 generates an electromagnetic wave for preventing the reading antenna 511b from reading the RFID tag 831 in the placement area 41c. In addition, when the reading control device 561 controls the reading antenna 521c to read the payment area 42c, the reading restriction control device 562 closes the switch of the reading restriction antenna 512c3 in the placement area 41c, so that the reading restriction antenna 512c3 generates an electromagnetic wave for preventing the reading antenna 521c from reading the RFID tag 831 in the placement area 41c.

[0614] In this way, in synchronization with the reading control device 561 driving the reading antenna to read in sequence, the reading restriction control device 562 closes the switch of the corresponding reading restriction antenna to generate an interfering electromagnetic wave.

[0615] As described above, according to the amusement table reading system 100 of the present embodiment, when multiple reading areas are set at relatively close intervals on the amusement table 6004, it is possible to distinguish which reading area these RFID tags 831 are located in. Specifically, even when multiple placement areas are set at relatively close distances from each other, by providing a reading antenna for each placement area 41, it is possible to prevent the reading antenna from reading the RFID tags 831 in adjacent placement areas 41 or payment areas 42. In addition, even when a payment area 42 is provided corresponding to each of the multiple placement areas 41 and a reading antenna is provided therein, it is possible to prevent the reading of RFID tags 831 in adjacent payment areas 42 or placement areas 41.

[0616] It should be noted that in the above-described sixth embodiment, the reading restriction antennas 512, 522, 532 generate an electromagnetic field for interfering with the reading of the corresponding reading area through the induced current generated by the electromagnetic field generated by the reading antennas 511, 521, 531 in adjacent reading areas. However, instead of this solution, an interfering electromagnetic field can be generated by passing a current through the reading restriction control device 562. In addition, in this case, a switch for blocking the loop can also be provided in the reading restriction antennas 512, 522, 532, and when the reading antennas 511, 521, 531 provided in the same reading area perform reading, control can be performed to open the switch to open the loop.
