[0002] This application is a divisional application of the Chinese patent application with the application date of May 19, 2020, application number 202010424893.8, and invention name: Game Coin Management System. Technical Field

[0003] The present invention relates to a game coin management system, which prevents the use of improper game coins in an amusement park or other game facilities using game coins. Background Art

[0004] Among the many table games played in amusement parks such as casinos, there is a card game. In the casino, game coins are used for such games.

[0005] The use of counterfeit game coins in casinos is prohibited. To prevent the use of counterfeit game coins in casinos, a technology exists that attaches RFID tags to game coins to verify their authenticity, thereby preventing the use of counterfeit game coins. Game coins with RFID tags are well known and are disclosed in Patent Document 1 (International Publication No. WO2008 / 120749). Summary of the Invention

[0006] Conventional gaming coins can use RFID to read information written to the storage area and verify the authenticity of the coin itself. However, it cannot record and verify information obtained during on-site use in casinos, particularly information related to the coin's owner. Therefore, even if the coin is genuine, RFID reading cannot detect the existence of a coin with an abnormal usage history, such as being used or exchanged by a different owner. Furthermore, it cannot prevent the use of such coin in casinos due to abnormal usage history.

[0007] Therefore, the purpose of the present invention is to provide a system that can grasp and manage the owner information of each game coin at all times and improve security when the dealer pays the game coin to the player and the owner of the game coin moves it from the casino to a certain player, so as to grasp and manage the owner information of each game coin at all times and improve security.

[0008] In order to solve the above-mentioned problems, the game coin management system of the present invention has the following features:

[0009] Game coins, which are attached with RFIDs that can be individually identified;

[0010] a game table for playing games using the game coins;

[0011] a game coin arrangement area on the gaming table for placing game coins placed by players participating in the game and game coins paid out by the dealer to the winners from the game coin tray on the gaming table;

[0012] a game coin reading device that reads the RFID of a game coin placed in the game coin arrangement area; and

[0013] A control device that grasps the reading result of the game coin reading device,

[0014] The control device can obtain information related to the owner of the game coin based on the RFID ID information of the game coin,

[0015] Furthermore, the control device is configured to identify a situation where a winner's placed game coin and a payment game coin paid to the winner are moved outside the game coin configuration area, and to associate the ID information of the payment game coin with the ID information of the placed game coin that is moved outside the game coin configuration area at the same time as the payment game coin on a database.

[0016] Furthermore, the system has a function of associating information related to the owner of the placed game coin indicated by the RFID of the placed game coin with the ID information of the RFID of the paid game coin on a database.

[0017] In addition, the game coin configuration area is further structured to be divided according to each player position, and has a pair area for placing the payout game coins according to each player position.

[0018] The coin reading device may be further configured to distinguish and read the pair areas according to the position of each player. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] (First embodiment)

[0044] use Figure 1 An overall overview of the table game management system according to the first embodiment of the present invention will be described. Figure 1 This diagram shows an overview of the entire system. A card game table 1004 has areas for player 1441, banker 1442, tie 1443, player pair 1444, and banker pair 1445, arranged for each player position 1131-1135. Furthermore, a coin placement area 1025 is provided at each player position, along with a coin reader 1002 for reading the RFID tags of coin 1001 placed within the coin placement area.

[0045] In addition, each coin arrangement area 1025 is provided with a pair area 1026 for placing coins 1001 taken out from the coin tray 1009 of the gaming table 1004 when the dealer pays the winner the coins 1001.

[0046] Furthermore, the controller 1003 is provided to grasp the reading result of the RFID of the token 1001 read by the token reading device 1002 .

[0047] At the beginning, the player who participates in the game places a game coin 1001 in the placement area within the game coin configuration area. The RFID of the placed game coin 1001 is read by the game coin reading device 1002, so that the control device 1003 obtains information about the owner of the game coin 1001 associated with the ID information of the RFID in the database.

[0048] Based on the result of the game, if the casino wins, the dealer collects the game coins 1001 placed by the loser and puts them into the game coin tray 1009. The game coin reader 1002 captures the RFID of the game coins 1001 in the game coin tray 1009, and the control device 1003 records the information that the owner of the game coins 1001 collected by the casino is the casino in the database.

[0049] Based on the result of the game, the dealer pays the winner an amount of gaming coins 1001 corresponding to the amount of the placed gaming coins from the gaming coin tray according to the rules of the game.

[0050] When making a payment, the payment game coin can be placed in the above-mentioned pair area 1026, or in the game coin configuration area outside the pair area.

[0051] Here, use Figure 2 The method of recording the owner information of the game coins paid is explained. Figure 2 This is a method of recording information related to the owner of the game token 1001 when the game token payment is paid to the winner.

[0052] In the situation that a plurality of players will place game coins and be placed in the same player position, there are 2 piles or more than 2 piles, the game coin reading device 1002 will be placed on the game coin 1001 in the game coin configuration area 1025 and read together, therefore, in the game, do not grasp which game coin 1001 belongs to which player, and obtain the ID1010 of the game coin placed.After the win or loss result of the game is determined, when paying the winner, the dealer pays each player (every pile) from the game coin tray 1009. The game coin 1001 taken out from the game coin tray 1009 is placed in the game coin configuration area 1025. The game coin reading device 1002 reads the ID1011 of the payment game coin placed in the game coin configuration area 1025.

[0053] The paid game coin 1001 is received by the winner along with the originally placed game coin 1001. At this point, the placed game coin and the paid game coin have moved outside the game coin arrangement area 1025, and therefore, the IDs of the placed game coin and the paid game coin disappear from the reading result obtained by the game coin reader 1002. Thus, the control device 1003 associates the information related to the owner of the placed game coin to determine to which player the paid game coin was paid.

[0054] The control device 1003 associates the acquired information on the owner of the paid token with the ID of the token in the database and stores the information.

[0055] Based on the above, the owner of the game coin 1001 can be traced. When the game coin 1001 is improperly received, it can be discovered that the owner information stored in the database is different from the actual owner.

[0056] Furthermore, the actual owner can be identified by utilizing facial recognition technology and ID such as membership cards.

[0057] In the above description, the ID of each token is managed on the database, but the token 1001 itself may be configured to store owner information.

[0058] Furthermore, the pair area 1026 may be configured such that, in addition to being provided for each player position, the area is configured independently of each player position and the token reading device 1002 reads the token independently.

[0059] Furthermore, it is also possible to configure such that, depending on the reading performance of the coin reading device 1002 , it is possible to select whether to use the sub-area 1026 or not.

[0060] Furthermore, the desktop game management system can also be constructed to combine an RFID reader that reads the game coins in the game coin tray 1009 through RFID, a camera that reads the placed game coins, a winning or losing result determination device such as a card shoe that determines the winning or losing result of the game, etc., to mutually utilize information.

[0061] (Second embodiment)

[0062] First, the game coins used in the game coin management system according to the embodiment of the present invention will be described. Figure 3 A game token 1 used in the same system is shown. In the same figure, an RFID tag 2 capable of storing various information is embedded in the game token 1. The RFID tag 2 includes a data-unrewritable area 21 and a data-rewritable area 22.

[0063] The non-rewritable data area 21 stores information about the game coin 1 that does not change during use, information that is not changed, or information that cannot be changed as fixed information 3. Specifically, the game coin 1's production information, product information, casino information, amount information, serial number, etc. are stored as fixed information 3. Production information includes the date and manufacturing machine of the game coin, and product information includes, for example, information indicating the game coin used in the casino's VIP area and information indicating the type of game coin (for example, information indicating whether it is a transfer code or a cash code).

[0064] The data non-rewritable area 21 may be a functionally non-writable area in the form of the RFID tag, or may be a locked area so that after necessary information is written in the writable area, no further data can be written.

[0065] The data area 22 can be rewritten to store information that changes during the use of the game coin 1 as the change information 4. For example, Figure 3 As shown, location-related information 220 including information 221 on date and time, information 222 on location and event, information 223 on owner, and the like is stored as change information 4 .

[0066] In order to prevent others from illegally reading and writing information, the fixed information 3 and the variable information 4 can be encrypted. In addition, the fixed information 3 and the variable information 4 can be stored as metadata.

[0067] Figure 4 An example of a method for recording data representing the change information 4 of the game coin 1. Figure 4 As shown, it is constructed by treating the location-related information 220 consisting of date, time information 221, place, event information 222, and owner information 223 as a block, and linking the information of the block into a chain, so that the historical record of the location-related information 220 of the game coin 1 can be grasped.

[0068] exist Figure 4 The following figure shows an example of the change information 4 stored in a game coin 1. The following information allows the movement of the game coin 1 to be understood. At 4:02 PM on January 28, 2019, Mr. A exchanged cash for a game coin 1 at counter 5. At 4:15 PM on the same day, Mr. A used the game coin 1 to place a bet at table No. 325. At 4:43 PM on the same day, Mr. B received the game coin 1 at table No. 325 as compensation for his bet. At 5:01 PM on the same day, Mr. B left the casino with the game coin 1.

[0069] like Figure 4 As shown, the change information 4 can be configured to store only the latest information, or it can store all written location-related information. Furthermore, a few of the multiple location-related information can be selected for storage. When selecting a few to store, multiple location-related information can be stored, including at least the latest location-related information 220 among all the location-related information 220. According to the above structure, the change information 4 of a particular game coin 1 can be used to understand the history of the game coin 1's use or movement. In other words, the traceable information of the game coin 1 is configured to be written into the game coin 1 itself and can be obtained.

[0070] Next, the management system of the gaming coins 1 according to this embodiment will be described. Figure 5This shows the overall overview of the same system.

[0071] First, in the factory 6 , the gaming coin 1 has the change information 4 including the information of manufacturing completion or factory shipment written as the location-related information 220 into the data rewritable area 22 of the RFID tag 2 by the writing device 14 .

[0072] The casino's backstage 7 receives and processes the game coins 1 shipped from the factory 6. In the backstage 7, the reader 13 reads the change information 4 stored in the rewritable area 22 of the game coin 1. Based on the read result, the management control device 15 determines whether the location-related information 220, which should have been written at the factory 6, has been written as the latest change information 4. If there is no record of writing at the factory 6, the game coin is considered to be fraudulent and an error signal is generated. This allows the casino to refuse to accept the game coin or to request an investigation from the factory. If the write record is correct, the backstage location-related information 220 is written to the rewritable area 22 of the RFID tag 2 via the writer 14. During writing, the backstage location information can be added to the factory location information, or the factory location information can be deleted and the backstage location information recorded instead. Furthermore, the reading and writing of the game coins in the backstage 7 can be performed simultaneously with the normal verification and activation of the game coins.

[0073] The game coins 1 that have completed the reception inspection in the background 7 are transported to the warehouse 8 or counter 9 of the casino. In the warehouse 8 or counter 9, the reading device 13 reads the change information 4 stored in the area 22 where data can be rewritten on the game coins 1. Based on the reading result, the management and control device 15 determines whether the information that should be written, that is, the location-related information 220 that has been written in the background 7, has been written as the latest change information 4. In addition, it is possible to check whether the information representing the factory 6 is written into the historical record of the change information 4. Similar to the aforementioned inspection in the background 7, the management and control device 15 determines whether there are any abnormalities in the historical record of the location information. If there is no problem with the reading result, the writing device 14 writes the location-related information representing the warehouse 8 or counter 9 into the area 22 where data can be rewritten.

[0074] A player purchases a game coin 1 at the counter 9. When the player purchases the game coin 1, a writing device 14 located at the counter 9 writes information indicating the time the coin was purchased and the change in owner from the casino to a guest as change information 4. Alternatively, the player may be identified and recorded using facial recognition technology, a casino membership card, an ID card, or the like.

[0075] Players play by using purchased game tokens 1 and placing them in the placement area 11 on the gaming table. A reader 13 reads location-related information 220, consisting of date and time information 221, location and event information 222, and owner information 223, from the RFID tag 2 of the placed game token 1. The management control device 15 then determines whether there are any abnormalities. For example, abnormalities can be determined in the following cases: a certain amount of time has passed since the last recorded gaming table usage information or purchase information at the counter; or the owner information 223 stored on the game token 1 differs from the owner information 223 determined through facial recognition or an ID card.

[0076] If the reading result is correct, the writing device 14 writes information 220 related to the location of the placed game coin 1 to the rewritable data area 22. The location-related information 220 includes date and time information 221, location and event information 222, and owner information 223. At the gaming table, for example, the writing device 14 writes change information 4 including the position number of the player where the game coin 1 is placed and the player's information. The player's information can be determined using an ID card or facial recognition. Typically, since multiple game coins 1 are placed overlapping in the placement area 11, they are written together while overlapping.

[0077] When a player takes a game coin 1 out of the casino, they exit the casino at the entrance 10. During exit, the reader 14 reads the location-related information 220, and the management control device 15 determines whether the change information 4 is normal. Furthermore, at the entrance 10, the writer 14 writes the change information 4, including the exit location, event information 222, and owner information 223.

[0078] When a player enters the casino and brings back previously taken-out game coins, the reading device 13 reads the information related to their location, and the management control device determines whether the change information 4 is normal. For example, if the owner of a game coin temporarily taken out of the casino is different when leaving the casino than when entering, the player can detect the receipt of game coins outside the casino.

[0079] If the reading result of the reader 13 is determined to be abnormal, the management and control device 15 can output an alarm to the counter 9 or the entrance 10. When exchanging a game coin 1 at the counter 9 or exiting the casino through the entrance 10, the owner of the game coin 1 can refuse to exchange it based on the alarm output by the management and control device 15, or have it individually inspected before exiting. Furthermore, if the result of the abnormality is determined, the management and control device 15 issues a warning to the dealer at each gaming table to interrupt the game, or to the gaming table, allowing the table manager to decide whether to interrupt or continue the game, or to replace the game coin 1. Alternatively, the management and control device 15 can be connected to the casino's overall management and control device 18 to issue a warning to the overall management and control device 18.

[0080] Similarly, the management and control device 15 can read the change information 4 by the reader 13 during exchange at the counter and determine if there is an abnormality. Specifically, an abnormality can be determined in the following cases: if a certain period of time has passed since the last recorded usage information at the gaming table or exchange information at the counter, or if a person different from the owner information 223 stored in the game coin 1 attempts to exchange. If an abnormality is determined, the management and control device 15 can output a warning and refuse to exchange the game coin 1 determined to be abnormal.

[0081] In the above description, the reading device 13 reads and the management control device makes a decision, and then the writing device 14 writes. However, a configuration in which reading and writing are performed simultaneously is also possible.

[0082] Hereinafter, application examples of the present invention will be described in detail.

[0083] At the factory 6, when production is completed or shipped, the RFID tag 2 is read and / or written. Production information and product information are written as fixed information 3, locked so that it cannot be rewritten as needed, and variable information 4 is written.

[0084] In the background 6, the game coins 1 shipped from the factory are received, and when the game coins 1 are activated to be usable, the RFID tags 2 are read and / or written.

[0085] In the warehouse 8, when the game coin 1 is moved from the warehouse 8 to the counter 9, or when the game coin 1 is moved from the counter 9 to the warehouse 8, the RFID tag 2 is read and / or written. Alternatively, for the game coin 1 stored in the warehouse 8, the RFID tag 2 can be read and / or written at regular intervals or at specified times.

[0086] At the counter 9, RFID tags 2 are read and / or written when coins are moved to or from the warehouse 8, or when game coins 1 are exchanged. When an exchange is performed at the counter 9, the location of the exchange, event information 222, and information about the player who made the exchange are written as owner information 223 of the variable information 4. Owner information 223 can be obtained from the player's casino ID card, facial recognition system, credit card, etc.

[0087] When a player enters or exits the casino, the RFID tag 2 is read and / or written. For all game coins 1 taken out of the casino upon exiting, the location and event information 222 indicating the location of the removal, and the owner information 223 indicating the player taking the game coins out are written as variable information 4 and registered. Similarly, upon re-entry, the location and event information 222 indicating the location of the entry, and the owner information 223 indicating the player taking the game coins in are written as variable information 4 and registered for the game coins 1 brought into the casino.

[0088] In the placement area 11, the RFID tag 2 is read and / or written for the game coin 1 placed by the player in the placement area 11 to participate in the game. In addition, the RFID tag 2 is read and / or written for the game coin 1 placed by the dealer in the placement area 11 as a compensation to the player.

[0089] In the coin tray 12 , the RFID tags 2 are read and / or written for the coins 1 collected in the coin tray and the coins 1 stored in the coin tray.

[0090] The gaming table also includes a payout area, and the RFID tag 2 can be read and / or written from the gaming token 1 placed in the placement area 11 by the dealer as a repayment to the player.

[0091] The management control device 15 has a function for determining whether there are any abnormalities in the location-related information 220 obtained from the reading results of the reading device 13 at each location. The abnormality determination can be based on whether the location-related information 220 has not been used for a predetermined period of time or longer since the last write, or whether the location-related information that should have been written has not been written.

[0092] If the data has not been used for a specified period of time or longer since the last write, any of the following situations may occur.

[0093] 1) The latest location-related information is the information indicating counter 9, and the next information is written after a specified time period;

[0094] 2) The latest location-related information is the information indicating entry at the entrance 10, and the next information is written after a specified time period;

[0095] 3) The latest location-related information is information indicating exit at the entrance 10, and the next information is written after a predetermined time has passed.

[0096] The situation where the location-related information that should be written is not written is any of the following situations:

[0097] 4) When entering the amusement park, the latest location-related information in the rewritable data area 22 of the game coin 1 is not written with information indicating exit at the entrance 10;

[0098] 5) When used at the counter 9, the information indicating the backstage 7 is not written;

[0099] 6) When exiting the amusement park, information indicating the counter 9 or the backstage 7 is not written.

[0100] The management control device 15 can determine any of the following situations based on the information 223 related to the owner obtained by the reading device 13 as a judgment on whether it is abnormal:

[0101] 1) A person who is different from the final owner of the data stored in the rewritable data area 22 exchanges the game coin 1 in the casino or exits the casino;

[0102] 2) A person who is different from the owner at the time of exiting the game and stored in the rewritable data area 22 brings the game token into the casino.

[0103] The management control device 15 determines whether any of the following 1) to 4) is abnormal based on the information indicating the location of the placement area 11, the information indicating the location of the coin tray 12, or the information indicating the payment area obtained by the reading device 13:

[0104] 1) A person who is different from the final owner of the data stored in the area 22 where data can be rewritten uses the game coin 1 at the gaming table;

[0105] 2) For a game coin 1 that has no record of being used at the gaming table, it is exchanged at the counter 9 by a different person from the one who purchased the game coin 1 at the counter 9;

[0106] 3) Using a game coin 1 without information indicating the counter 9 or backstage 7 in an amusement park;

[0107] 4) The latest location-related information is information indicating the placement area 11 or the payment area. After a specified time has passed, the card can be exchanged at the counter 9 or used at a gaming table.

[0108] Figure 81 shows a database according to another embodiment of the present invention. The management system includes a database 17 that records the same fixed information 3 and variable information 4 as the game coin 1. Based on the reading results of the reader 13, the management control device 15 can record the information in the database 17 and compare the fixed information 3 and variable information 4 stored in the game coin 1 with the information in the database to determine any abnormalities.

[0109] In the RFID tag 2 of this embodiment, the functionally unwritable area of the data-unwritable area 21 may be a TID (Tag ID). After the necessary information is written to the data-unwritable area 21, the area locked to prevent data from being rewritten may be an EPC or user area. The data-unwritable area 22 may be an EPC (Electronic Product Code) or user area.

[0110] The reading device 13 and the writing device 14 can change their forms according to the location. For example, in the factory 6, Figure 6 The device shown on the table has a box-shaped entrance and exit 10. Within the storage area 11 and the coin tray 12, these areas themselves can function as a reader 13 and a writer 14. Furthermore, the coins 1 can be read while stacked or stored in a coin box. Furthermore, the reader 13 and writer 14 can be integrally formed.

[0111] In the above embodiment, a gaming coin is provided with a single RFID tag having an area where data cannot be rewritten and an area where data can be rewritten. Alternatively, a gaming coin may be provided with two RFID tags, one of which stores fixed information and is locked to prevent rewriting, while the other stores variable information and is therefore pre-set to allow rewriting.

[0112] However, in this case, the following problems may arise: when multiple game coins are read together, Figure 7A As shown, since the information group of fixed information 3 and the information group of variable information 4 can be read separately, the combination of fixed information and variable information of a specific game coin cannot be determined, and the game coin with abnormal variable information cannot be identified.

[0113] In this regard, when there is only one RFID tag, Figure 7B As shown, even when multiple game coins are read together, the correspondence between the fixed information and the variable information read by the reading device can be grasped. Therefore, it is considered better to implement it through a single RFID tag.

[0114] Furthermore, since a larger RFID tag's diameter generally improves reading accuracy, when inserting an RFID tag into a gaming coin, it's desirable for the RFID tag to have a diameter at least equal to the coin's radius. However, inserting two RFID tags into a gaming coin reduces the diameter of each RFID tag, making this undesirable. Furthermore, inserting two RFID tags increases the number of RFID tags to be read, resulting in a slower reading speed when reading multiple gaming coins.

[0115] From the above aspects, it can be considered that implementation with a single RFID tag is more effective.

[0116] (Third embodiment)

[0117] The following is an overview of the overall management system for table games in a casino having a plurality of gaming tables according to an embodiment of the present invention. Figure 9 As a diagram showing an overall overview of the same system, a management system for table games in a gaming hall having multiple gaming tables 2004 includes: a game recording device 2011, which records the games played on the gaming tables 2004, including the gaming coins 1, as images via multiple cameras 2002; an image analysis device 2012, which performs image analysis on the recorded images; a gaming coin reading device 25, which reads the RFID attached to the gaming coins 1; and a game result determination device 18, which determines and displays the game results of each game played on the gaming tables 2004.

[0118] The game outcome determination device 18, for example, is a card-delivering device 2003, a so-called electronic dealing shoe commonly used by those skilled in the art. It is configured to pre-program the game rules, read information from the dealt cards C, and determine the outcome of the game. For example, in certain card games, the banker's win, the player's win, and a tie (or draw) are primarily determined by the face value of two or three cards. The result (win or lose) is indicated by the result display light 2013.

[0119] In the same figure, the game table 2004 is a table for a card game, and is provided with five seat numbers 13 ("Seat Number 1" 131, "Seat Number 2" 132, "Seat Number 3" 133, "Seat Number 5" 134, "Seat Number 6" 135), and 5 game participants can participate in the game. A placement area 44 is set for each seat number 13. The placement area 44 of the seat number 13 includes areas for the player (PLAYER) 441, the banker (BANKER) 442, the tie (TIE) 443, the player pair (P) 444, and the banker pair (B) 445. Each game participant plays the game by placing the game coin 1 of the amount to be placed at the position corresponding to the placed object. Figure 9For example, two coins 1 are placed on the tie 443 at seat number 5, and two coins 1 are placed on the player 441 at seat number 5, thereby playing the game. The gaming table 2004 is also provided with a player card area 45 for placing the drawn player cards and a banker card area 46 for placing the drawn banker card.

[0120] The control device 2014, using the camera 2002 and the image analysis device 2012, can determine where each player 2006 places a game coin 1 in the placement area 2008 (player, banker, tie, pair), the type of game coin 1 placed (game coins 1 are divided into different amounts by color), and the number of game coins placed. For example, it can determine that two game coins were placed in the tie 443 of seat number 5 and two game coins were placed in the player 441.

[0121] like Figure 9 As shown, the game coin reading device 25 is configured to read the RFID of the game coin 1 in the reading area according to each seat number using the entire placement area as a reading area. The RFID attached to the game coin 1 is written with inherent ID information, the amount, type, manufacturing information, owner information, etc. of the game coin 1. Alternatively, the ID information can also be stored in a database in association with the amount, type, manufacturing information, owner information, etc. of the game coin 1. The game coin reading device 25 can grasp the game coin 1 according to each seat number by reading the RFID attached to the game coin 1, and then can grasp the total amount or number of pieces. That is, for example, it can be grasped that 4 game coins are placed at seat number 5, as well as their respective types, amounts, and IDs.

[0122] like Figure 10 As shown, based on the image analysis results of the image analysis device 2012, the control device 2014 determines the total amount or total number of game tokens 1 for each seat number based on the type and number of game tokens 1 placed in each placement area of each seat number. The control device 2014 compares the total amount or total number of game tokens 1 for each seat number with the total amount or total number of game tokens 1 for each seat number obtained based on the RFID information of the game tokens 1 read by the game token reader 25 to determine whether they are consistent. Furthermore, the seat number determined to be inconsistent can be output, thereby identifying the problematic seat number.

[0123] If the total amount or total number of game coins 1 for each seat number obtained based on the reading result of the game coin reading device 25 is less than the total amount or total number of game coins 1 for each seat number obtained based on the image analysis result of the image analysis device, it is considered that there is a possibility that the RFID attached to the game coin 1 is damaged, the RFID is unreadable, or the game coin 1 has no RFID attached. Figure 10In the example, for the gaming coin 1 placed in seat number 1, the total number of reads obtained by the image analysis device 2012 is 4, whereas the total number of reads obtained by the RFID reading of the gaming coin reading device 25 is 3. Therefore, it is considered that the RFID of one of the four gaming coins 1 placed in seat number 1 could not be read.

[0124] If the total amount or total number of game coins 1 for each seat number obtained based on the reading result of the game coin reading device 25 is greater than the total amount or total number of game coins 1 for each seat number obtained based on the image analysis result of the image analysis device, it is considered that there may be a situation where the image analysis device 2012 cannot read the game coins 1 due to reasons such as the game coins 1 entering the blind spot of the camera. Figure 10 In the example, for the gaming coin 1 placed in seat number 3, the total number of reads obtained by the image analysis device 2012 is 1, while the total number of reads obtained by the RFID reading of the gaming coin reading device 25 is 2. Therefore, it is possible that there are two gaming coins 1 placed in seat number 3, but the image analysis device can only recognize one.

[0125] The RFID ID information attached to the game coin 1 is registered in the casino's database, which records information about production and shipment at the factory, as well as receipt, verification, and activation at the casino. The control device 2014 compares the RFID information read by the game coin reader 25 with the information in the database to determine the authenticity of the game coin registered as a game coin to be used in the casino.

[0126] According to this structure, the type and number of game coins 1 placed in each placement area can be grasped by the camera, and fake or defective game coins 1 can be determined for each seat number based on the RFID information of the game coins 1 read by the game coin reading device 25.

[0127] The table game management system also includes a mechanism for identifying game participants using a facial recognition system or a player ID card. The control device 2014 can associate the game participant information identified by the game participant identification mechanism with the seat number. The control device 2014 can store deposit amounts, refund amounts, or redemption amounts, and win / loss information for each game participant, stored for each seat number. Furthermore, information about game participants who have played multiple games at multiple gaming tables can be stored together.

[0128] The control device 2014 can use the game coin tray determination device 12 to determine the total amount of game coins 1 in the game coin tray 17 of the dealer 2005 of the game table 2004, and can compare and calculate whether the total amount of game coins 1 in the game coin tray 17 has increased or decreased based on the amount of lost game coins 1 placed by each player 2006 and the amount of game coins paid to the winning player 2006 based on the amount of lost game coins 1. The game coin tray determination device can be configured to use the camera 2002 to capture the game coins 1 stored in the game coin tray 17 and analyze it based on the image analysis device to grasp the total amount of game coins 1 in the game coin tray 17, or it can be configured to be configured to be provided with an RFID reader on the game coin tray 17 to detect the total amount of game coins 1 stored in the game coin tray 17.

[0129] In this example, cheating and errors can be detected based on the winning or losing results of the game, the information of how many and which type of game coins 1 are placed at which position in the placement area 2008 (player, banker, tie, or pair), and the increase or decrease in the amount of game coins 1 in the game coin tray 17 after the recovery of lost game coins and the repayment of won game coins 1. Therefore, even if the movement of the game coins 1 after the game is over is not known, that is, whether the placed game coins 1 move to the player side or to the dealer side, cheating and errors can be detected.

[0130] For example, in the case of a card game, the card issuing device 2003 reads the face value of the card C drawn in the game, thereby determining the game's win or loss according to the rules of the card game. Alternatively, the game table 2004 may be photographed by the camera 2002, analyzed by the image analysis device 2012, and compared with the game rules by the control device 2014 to determine the game's win or loss. In this case, the camera 2002, the image analysis device 2012, and the control device 2014 constitute a game outcome determination device. Information on the number of game coins 1 and the type of game coins 1 placed by each player in seat number 7 in the placement area 2008 (player, banker, tie, player pair, banker pair) can be obtained by photographing the game coins 1 placed in the placement area 2008 with the camera 2002 and analyzing the images for each playing position 7 with the image analysis device 2012.

[0131] In addition, the increase or decrease in 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: the total amount of 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 is compared with the total amount of 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.

[0132] For example, the total amount of game coins (1) in the coin tray 17 before the game begins is set to Bb, and the total amount of game coins (1) in the coin tray 17 after the game ends and the lost game coins (1) are recovered and the won game coins (1) are repaid is set to Ba. Furthermore, in this game, the total amount of all play positions (7) of the game coins (1) placed in the player area is set to bp, the total amount of all play positions (7) of the game coins (1) placed in the banker area is set to bb, and the total amount of all play positions (7) of the game coins (1) placed in the tie area is set to bt. For example, if the game ends in a banker win, Ba - Bb = bp - bb + bt should hold. Alternatively, the total amount of game coins (1) in the coin tray 17 after the game ends should be (Bb + bp - bb + bt). If the above conditions do not hold, it can be determined that cheating or errors occurred in the recovery or repayment of game coins.

[0133] exist Figure 14A Detailed diagram of the coin tray of this embodiment is shown in FIG. Figure 14B 1 is a diagram showing another example of a game coin tray. The game coin tray 17 is provided with: a game coin recovery tray 171, which recovers and temporarily stores the game coins 1L placed by the losing player 2006L; and a game coin repayment tray 172, which 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 incremental amount of the game coins 1L in the game (the expected 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 expected total amount with the actual total amount, and determine whether there is a discrepancy.

[0134] Furthermore, the control device 2014 is capable of repaying the corresponding game coins 1, and at the end of the repayment, compares the total amount of the game coin tray obtained based on the repayable amount of the game coins in the game with the actual total amount of the game coin tray, and determines whether there is a difference between the total amount and the actual total amount. The repayable amount of the game coins in the game is calculated based on the position, type and number of the game coins placed by each game participant on the gaming table, and the game results.

[0135] In addition, by repaying the winning player 2006W with 1W of game coins, the image analysis device 2012 and the control device 2014 can ensure sufficient time to grasp the actual total amount of game coins 1L in the recovered game coin tray 171 after recovery by using 1W of game coins in the recovered game coin tray 172.

[0136] As described above, in this embodiment, the control device 2014 calculates the balance of game coins based on the amount of game coins placed on the gaming table 2004 and the game results during each game, and verifies the increase in the balance in the game coin tray 17 after the game. If a discrepancy is detected during this verification, the control device 2014 issues a warning or adds a record indicating the detection of the discrepancy to the image recorded by the camera 2002. By confirming the image, the casino operator can investigate the cause of the discrepancy.

[0137] In the management system of the tabletop game of this embodiment, the total amount of game coins 1 in the game coin tray 17 before each game is settled is added or subtracted from the increase or decrease amount of the game coins in the game calculated based on the position, type and number of the game coins 1 placed by all the players 2006 in the game, and the win or loss result of the game obtained by the win or loss result determination device. The total amount of game coins 1 in the game coin tray 17 after settlement at the end of the game is compared with the actual total amount of game coins 1 in the game coin tray 17 at the end of the game obtained with the aid of the image analysis device 2012, and it is determined whether there is a difference between the total amount and the actual total amount.

[0138] The control device 2014 uses the image analysis device 2012 to grasp the position, type and number of game coins placed by each player. When all the lost game coins placed by each player are recovered, the actual total amount of game coins in the game coin tray is grasped, and the expected total amount of game coins 1 in the game coin tray 17 is compared with the actual total amount of game coins 1 in the game coin tray 17, and it is determined whether there is a difference between the expected total amount and the actual total amount, wherein the expected total amount of game coins 1 in the game coin tray 17 is the total amount in the game coin tray before each game is settled, plus the increase in the game coin tray 17 in the game obtained according to the position, type and number of the game coins placed by the losing player.

[0139] The control device 2014 adds the total amount of game coins 1 in the game coin tray 17 before the settlement of each game to the increase in the game coin tray 17 in the game obtained by adding the position, type and number of game coins 1 placed by the losing player, and compares it 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 and the actual total amount, and the total amount of game coins 1 in the game coin tray 17 after actuation at the end of the game is compared with the actual total amount of game coins 1 in the game coin tray 17 at the end of the game obtained with the aid of the image analysis device 2012, and if it is determined that there is a difference between the total amount and the actual total amount, it is determined to be a payment error, and a payment error signal is generated to notify the payment error.

[0140] The game coin tray 17 is provided with a game coin recovery tray 171, which recovers and temporarily stores the game coins 1L placed by the losing player. The image analysis device 2012 compares the expected total amount of the game coins 1L in the recovered game coin tray 171 with the actual total amount of the game coins 1L in the recovered game coin tray 171, and determines whether there is a difference between the expected total amount and the actual total amount, wherein the expected total amount of the game coins 1L in the recovered game coin tray 171 is obtained by adding the increase in the game coins 1 in the game calculated according to the position, type and number of the game coins 1L placed by the losing player. 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 in the amount of game coins calculated based on the amount of game coins placed by all players and the winning or losing results of the game, in order to be able to analyze the game records that produce the above-mentioned difference in the game recording device 2011, the game recording device 2011 can assign an index or moment to the obtained image, or determine and regenerate the recovery scene or payment scene of the game coins 1.

[0141] 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 situations 1) to 4) occurs:

[0142] 1) When the repayment of the won game coin 1 is completed;

[0143] 2) When the card C used in the game is recovered and discarded in the discard area 41 or discard slot 42 of the table;

[0144] 3) When a prescribed button attached to the winning / losing result determination device is pressed;

[0145] 4) When the symbol 43 indicating winning or losing is restored.

[0146] Furthermore, the control device 214 utilizes artificial intelligence or a deep learning architecture as follows: it is capable of understanding the position (for the player, banker, or pair) and amount (type and number) of game coins placed at each playing position 7 of the gaming table 2004, comparing the win / loss history of each player 2006 and the amount of game coins (win amount) obtained from the win / loss results of each game with a large amount of past (big data) game statistics, and detecting abnormal conditions (set by the casino). Typically, the control device 214 utilizes artificial intelligence or a deep learning architecture as follows: if a win amount exceeding a certain amount (1 million points) occurs, or if a situation in which the amount of game coins placed at a playing position 7 of a gaming table 2004 is small during a loss and large during a win, and is compared with past game statistics (big data, etc.), it is capable of detecting abnormal conditions.

[0147] Furthermore, the control device 2014 (integrated with the image analysis device 2012) of the table game management system is configured to identify individual players 2006 at playing positions 7 where abnormalities have been detected, or at playing positions 7 where wins have exceeded a specified amount. To identify these players 2006, the image analysis device 2012 extracts facial images using features and assigns identification numbers (such as IDs) to the players. Furthermore, the control device 2014 includes a warning function that notifies the table of the presence of a specific player 2006 when the player leaves their seat and relocates to another table. Specifically, the warning is sent to the table manager or the person in charge (or dealer) of each table 2004, thereby preventing further abnormalities.

[0148] The control device 2014 can determine the game tokens 1 collected for each seat number based on the RFID ID information of the collected game tokens 1 determined by the game token tray determination device and the RFID ID information of the game tokens 1 read by the game token reading device 25.

[0149] exist Figure 11 In, such as Figure 12 as well as Figure 13 As shown in the detailed table, the game coin 1 is placed. According to the analysis of the image analysis device 2012, the place (player, banker, etc.) and the number (and amount) of game coins 1 can be grasped. On the other hand, according to the reading of the game coin reading device 25, the ID of the RFID attached to the game coin 1 for each seat number can be grasped. Furthermore, since the game coin tray determination device 25 can determine the ID of the game coin 1 in the game coin tray 17, it is possible to grasp the ID added before and after the recycling, so that the recycled game coins 1 can be grasped. In Figures 11 to 13In the case where the game result is that the dealer wins, according to the analysis results of the image analysis device 2012, it can be known that the two game coins placed on the dealer pair should be recovered, and it can be known that among the IDs of the recovered game coins determined by the game coin tray determination device, the two game coins ID6 and ID18 placed on seat number 5 read by the game coin reading device 25 are recovered.

[0150] Furthermore, the control device 2014 can determine the total amount or number of game coins (1) to be collected for each seat number by using the game result obtained by the game result determination device and the detection results of the position, amount, and number of game coins (1) obtained based on the image analysis results of the image analysis device. Therefore, the control device 2014 can compare the total amount or number of game coins (1) collected for each seat number determined based on the RFID with the total amount or number of game coins (1) to be collected based on the image analysis results to determine whether they are consistent.

[0151] For example, when the reading result of the game coin reading device 25 at seat number 1 is "A, B, C, D, E", the analysis result of the image analysis device 2012 is "2 coins in tie, 2 coins for the dealer", the game result is "dealer wins", and the reading result of the game coin tray judgment device 18 is "A, B", it can be seen that the game coins A and B placed in the tie are correctly recovered.

[0152] Furthermore, the control device 2014 can determine whether the RFID ID information of the recovered game coin 1 determined by the game coin tray determination device is consistent with the RFID ID information of the placed game coin 1 read by the game coin reading device 25. Based on this determination, it can be determined whether the game coin 1 recovered by the game coin tray is the game coin placed on the game table, or whether it is a game coin 1 illegally recovered from other places.

[0153] Furthermore, the control device 2014 can determine the type of game coins such as cash codes, transfer codes, promotional codes, etc. based on the RFID information read by the game coin reading device 25, and can store the amount placed, the recovered amount or the reimbursement amount according to each determined type of game coins.

[0154] Transcodes are special game tokens that can be purchased by specific members and cannot be exchanged for cash. Transcodes are managed based on the amount purchased by each member. They must be used for gaming and consumption, and reimbursement for gaming with transcodes is done with cash codes. The amount of transcodes deposited or returned is stored based on RFID information read by the game token reader 25, allowing the amount of transcodes a specific member should hold to be tracked.

[0155] The game coin reading device 25 also has the function of confirming the area and can read the game coins 1 placed for redemption. Figure 15 As shown, in the case of making a repayment to the dealer of seat number 2, the game coin 1 for repayment is placed in the game coin reading device 25 and read. Figure 15 The winning coin 1 placed by the dealer at seat number 2 is placed next to the winning coin 1. The control device 2014 can compare the repayment amount determined based on the game result obtained by the game result determination device and the position, amount and number of the coin 1 obtained by the image analysis result of the image analysis device with the amount of the coin 1 placed at each seat number obtained based on the reading result of the coin reading device 25, and determine and output whether the repayment amount is consistent. Figure 16 In the example, the total number of game coins 1 to be paid for seat number 1 is 4, whereas the reading result of the game coin reading device 25 is 3, which is inconsistent. In the case of inconsistent repayment amounts, an inconsistent signal is output, and the dealer can re-place the game coins 1 for repayment based on the output signal. When the game coins 1 are re-placed, a judgment can be made again, and the judgment result can be output. The area where the game coins 1 for repayment are placed can be any position within the game coin reading device 25. In addition, if Figure 15 As shown, the payment confirmation area 26 can be arranged on the dealer side of the placement area separately from the placement area. Figure 15 In the process, the game coin 1 for repayment is placed on the payment confirmation area 26 of seat number 6, the game coin reading device 25 reads it, and the control device 2014 determines that the repayment game coin is placed next to the winning game coin 1 placed on the dealer.

[0156] In addition, the image analysis device 2012 also performs image analysis on the confirmation area, and the control device 2014 compares it with the reading result of the game coin reading device 25 to determine whether the total number of coins is consistent.

[0157] The control device 2014 can output a signal based on the determination made. The signal can be output by displaying it on the display of the coin tray 17 or the display of the card issuing device 13, or by the game station manager or the backstage of the casino.

[0158] The game coin reading device 25 can be as follows Figure 17 As shown, all placement areas are treated as a read area according to each seat number, or as Figure 18 As shown, for each seat, the player betting area and the banker betting area are combined into one reading area, and the tie betting area, the player betting area, and the banker betting area are combined into one reading area. Figure 19 and Figure 22As shown, the tie pair placement area, the player pair placement area, and the banker pair placement area may each be used as one reading area.

[0159] Next, the gaming token 1 used in the embodiment of the present invention will be described. Figure 20 This is the appearance of the game coin 1 used in this system. Figure 21 The front cross-sectional view. The game coin 1 is formed into the following multi-layer structure: a plurality of plastic layers of different colors are stacked, with at least a colored layer 101 in the middle, and a white layer 102 or a light-colored layer (although not shown, it can be a layer lighter in color than the colored layer 101) stacked on both sides of the colored layer 101 in the middle. Figure 20 As shown, a stripe pattern in the stacking direction is formed on the side, and by changing the color of the colored layer 101 (red, green, yellow, blue, etc.), the type of the game coin 1 (10 points, 20 points, 100 points, 1000 points, etc.) can be determined.

[0160] The coloring layer 101 may also be Figure 21 Shown by the colored multiple layers (in Figure 21 Because the colored multilayer (in Figure 21 There are 3 layers in the middle) are bonded to each other by heat pressure, so that Figure 21 As shown, the three-layer structure is not visible. Figure 21 The three layers are shown in the illustration. In addition, a partial hollow portion B is provided in the middle layer of the three layers of the colored layer 101, and an RFID is embedded in the hollow portion.

[0161] In addition, the game token 1 is not limited to a structure of laminated plastic layers, and may also have a structure having the same appearance as the colored layer 101.

[0162] The following describes in detail the method by which the image analysis device 2012 analyzes the game coin 1. The image analysis device 2012 performs image analysis on the image recorded by the recording device 11, identifying at least two colors: a specific color 121 at least partially attached to the game coin 1, and a reference color R present in the image that is different from the specific color 121. Furthermore, the specific color 121 is attached to the game coin 1 at a predetermined location or at least partially attached to the game coin 1 in a predetermined shape. For example, it can be attached as a colored layer 101, attached circumferentially to the side of the game coin 1, or attached to the surface of the game coin 1 as a predetermined mark. Furthermore, the reference color R can also be the color of a specific area of the gaming table 2004, or a color attached to a location on the game coin 1 that is different from the specific color 121.

[0163] The image analysis device 2012 includes, for example, an artificial intelligence device 12a that identifies a specific color using deep learning technology, and determines the number and type of gaming tokens 1 placed on the gaming table 2004. The image analysis device 2012 can also determine the position of the gaming tokens 1 on the gaming table 2004.

[0164] The image analysis device 2012 acquires multiple images of a game coin 1 and a reference color R illuminated at different illumination levels. Through manual teaching, the acquired images and the correct color of the specific color 121 and reference color R of the game coin 1 in each image are used as training data for learning, thereby creating a learning model 13a (recognition program). Furthermore, for images of the game coin 1 and the reference color R illuminated under the same illumination conditions, the specific color 121 and the reference color R are illuminated at the same illumination level to determine the relative relationship between the specific color 121 and the reference color R. This relative relationship can be used, for example, to identify the specific color 121.

[0165] In addition, the image analysis device 2012 may also not use artificial intelligence, but may use the camera 2002 to shoot and record as an image, and use the results of the image analysis to detect features on the image such as shape, brightness, color saturation, and hue, thereby extracting the center line C of the game coin 1.

[0166] The artificial intelligence device 12a further has a configuration for performing image analysis on a predetermined range of the extracted peripheral image around the center line C (e.g., a range of eight pixels centered on the center line and perpendicular to the center line), thereby identifying at least two colors, the specific color 121 and the reference color R different from the specific color 121, in the peripheral image. Furthermore, when performing image analysis on the predetermined range of the extracted peripheral image around the center line C, the image may be analyzed directly or after performing image processing such as color enhancement or noise removal to facilitate identification of the specific color 121.

[0167] In summary, the artificial intelligence device 12a of the image analysis device 2012 has the function of extracting the center line C from the image of the game coin 1, and performing image analysis on the peripheral images within a specified range centered on the center line C, thereby identifying the structure of at least two colors of a specific color 121 and a reference color R different from the specific color 121 in the peripheral image, and the artificial intelligence device is taught using multiple peripheral images of the game coin 1 and the reference color R illuminated under different illumination as teacher data.

[0168] In other embodiments of the present invention, the control device 2014 further has the function of determining at least one of the following:

[0169] 1) In each game, whether there is no change in the game coins from the time the cards are drawn or the dealer starts the game until the card distribution device displays the winning or losing result of the game,

[0170] 2) After each game is over, while the dealer is collecting the game coins placed by the losers among the game participants, is there any change in the game coins caused by anyone other than the dealer?

[0171] 3) After each game is over, during the period when the dealer collects the game coins placed by the losers among the game participants, whether additional game coins are added,

[0172] 4) After each game is over, whether the dealer pays the position of the game coin placed by the winner among the game participants,

[0173] 5) After each game is over, whether the winner among the game participants has taken the game coins placed and the game coins paid.

[0174] Furthermore, the control device 2014 can also be configured to detect the movement of the hands of the dealer and the game participants, the movement of the game coins, or the movement of the hands and the movement of the game coins by using the analysis results of the image analysis device, so as to determine at least one of 1) to 5).

[0175] The control device 2014 has the following functions 1) to 5) according to the rules of a card game, and as a characteristic function of the present invention, it determines whether cheating that violates the rules is not performed.

[0176] 1) In each game, the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether there is no change in the game coin 1 from the time the signal for drawing the start card is obtained from the card issuing device 2003, or from the time the dealer 2005 presses the start button 4s to start the game, to the time the card issuing device 2003 displays the winning or losing result of the game.

[0177] 2) After each game is over, the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether the loser 6 among the game participants 2006 takes the game coin 1 without cheating during the period when the dealer 2005 recovers the game coin 1 placed by the loser.

[0178] 3) After each game is over, the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether people other than the dealer 2005 (winner or loser) have added the won game coins 1W or replaced the game coins 1 on the unplaced winning side during the period when the dealer 2005 recovers the game coins 1 placed by the loser among the game participants.

[0179] 4) After each game is finished, the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether the dealer 2005 correctly places the payout coin 1W at the position where the winner among the game participants 2006 places the coin 1.

[0180] 5) After each game is over (the dealer 2005 operates the card issuing device 2003 and causes the display light 13 to show the winning or losing result), the image analysis device 2012 uses the information obtained by the camera 2002 to monitor whether the winner 6W among the game participants 2006 has taken the placed game coins 1 and the paid game coins 1W.

[0181] Furthermore, in the above-described embodiment, the image analysis device 2012 and the control device 2014 are devices that utilize artificial intelligence or deep learning structures. Specifically, the image analysis device 2012 and the control device 2014 can be implemented using the Scale-Invariant Feature Transform (SIFT) algorithm, a convolutional neural network (CNN), deep learning, machine learning, or similar methods to perform image analysis and the various controls described above. These technologies perform image recognition on captured images to identify objects within the image. In recent years, deep learning techniques that utilize multi-layered neural networks have been gaining popularity for achieving high-precision object recognition. This deep learning technique generally achieves high-precision object recognition by overlapping multiple layers between the input and output layers of the neural network. Among these deep learning techniques, convolutional neural networks, in particular, have attracted attention due to their superior performance compared to conventional methods for identifying objects based on image features.

[0182] Convolutional neural networks learn from labeled target images and identify the primary objects within them. If multiple primary objects exist within the training image, they are designated using rectangular regions, and labels are assigned to the images corresponding to these regions for learning. Furthermore, convolutional neural networks can also determine the primary objects within an image and their locations.

[0183] Further explaining convolutional neural networks, the object recognition process involves extracting candidate regions based on local features, such as edge extraction, from the target image. These candidate regions are then fed into the convolutional neural network, where they are classified based on the extracted feature vectors. The most reliable candidate regions are then identified as the recognition result. Confidence is a measure of how much the similarity between a particular image region and the subject of the image learned along with the label is higher than other similarity levels.

[0184] Various embodiments of the present invention have been described above. However, the above embodiments can of course be modified by those skilled in the art within the scope of the present invention. The device of this embodiment can be appropriately modified according to the needs of the game to which it is applied.

[0218] 4) The latest location-related information is information indicating the placement area or payment area. After a specified time has passed, the card can be exchanged at the counter or used at a gaming table.

[0219] Furthermore, the information on the RFID tag may be encrypted.

[0220] Furthermore, the data-unrewritable area may be a structure in which data cannot be functionally rewritten, or a structure locked so that data cannot be rewritten.

[0221] Furthermore, the reading device is configured to read both the fixed information stored in the data non-rewritable area and the location-related information stored in the data rewritable area.

[0222] The management control device can be configured to extract and grasp the location-related information of the area where data can be rewritten stored in the same RFID tag from the multiple fixed information of the multiple game coins read by the reading device.

[0223] In order to solve the above-mentioned existing problems, the game coin of the present invention has a single RFID tag having an area where data cannot be rewritten and an area where data can be rewritten.

[0224] The area where data cannot be rewritten stores at least one of the production information, product information, casino information, amount information, and serial number of the game coin as fixed information.

[0225] The area capable of rewriting data is configured to store information related to the location of the game coin written by the writing device as change information.

[0226] The variable information stored in the data rewritable area of the same RFID tag can be extracted from the fixed information stored in the data non-rewritable area.

[0227] In addition, further, the game coins can be structured as follows: the fixed information stored in the area where the data cannot be rewritten of multiple game coins can be read together by a reading device, and based on the read fixed information, the location-related information stored in the area where the data can be rewritten can be read.

[0228] In order to solve the above-mentioned conventional problems, the table game management system of the present invention has the following features:

[0229] Game coins, which are attached with RFIDs that can be individually identified;

[0230] a game table for playing games using the game coins;

[0231] a game recording device for recording, by means of a camera, game coins placed by each game participant in a game played on the gaming table as images;

[0232] an image analysis device for performing image analysis on the recorded image of the gaming coin;

[0233] a coin reading device that reads the RFID attached to the coin placed by each game participant; and

[0234] A control device that grasps the image analysis results of the image analysis device and the reading results of the game coin reading device,

[0235] The gaming table has a plurality of placement areas, and the plurality of placement areas include at least a player placement area and a banker placement area according to each seat number.

[0236] The game coin reading device reads the game coins according to each seat number by treating all the placement areas as a reading area, or by dividing the entire area into a plurality of reading areas which are smaller than the number of the placement areas, and reading the game coins according to each reading area.

[0237] The control device has the following structure: based on the image analysis result of the image analysis device, it can independently grasp the type and number of the game coins placed in each placement area including at least the player placement area and the banker placement area, and determine whether the total amount or total number of game coins for each seat number or each reading area obtained based on the image analysis result of the image analysis device is consistent with the total amount or total number of game coins for each seat number or each reading area obtained based on the reading result of the game coin reading device, and output the determination result.

[0238] Furthermore, the control device may be configured to output seat numbers where the determination results are inconsistent.

[0239] The control device can also be structured as follows: when the total amount or total number of game coins for each seat number obtained based on the reading result of the game coin reading device is less than the total amount or total number of game coins for each seat number obtained based on the image analysis result of the image analysis device, a signal can be generated, which indicates that the RFID attached to the game coin may be damaged, or the RFID may not be attached to the game coin.

[0240] In addition, the control device can also be structured as follows: when the total amount or total number of game coins for each seat number obtained based on the reading result of the game coin reading device is greater than the total amount or total number of game coins for each seat number obtained based on the image analysis result of the image analysis device, a signal can be generated, which indicates that the reading of the game coins by the image analysis device may be erroneous.

[0241] In addition, a database is provided for storing the ID of the RFID attached to the game coin.

[0242] The control device may be configured 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, determine the authenticity of the game coin, and output the determination result.

[0243] In addition, it also has

[0245] a coin tray determination device capable of determining the type and number of the coins accommodated in the coin tray; and

[0246] A game result determination device that determines the game result of each game on each gaming table.

[0247] The control device has a calculation function for calculating the income and expenditure of the casino on the gaming table based on the collection and redemption of each game, using the game results obtained by the game result determination device and the measurement results of the position, amount, and number of game coins obtained based on the image analysis results of the image analysis device;

[0248] It can also have:

[0249] a recovery determination function for comparing the expected recovery amount of game coins in the game with the actual recovery amount of the game coin tray when the recovery of the lost game coins placed by each game participant is completed, and determining whether there is a difference between the expected recovery amount and the actual recovery amount, thereby determining whether there is cheating or error in the recovery of the game coins, wherein the expected recovery amount of game coins in the game is calculated based on the position, type and number of game coins placed by each game participant on the gaming table and the game result; and

[0250] A repayment judgment function is used to repay the corresponding game coins. At the end of the repayment, the total amount of the game coin tray obtained based on the amount of game coins to be repaid in the game is compared with the actual total amount of the game coin tray. If a difference is determined between the total amount to be repaid and the actual total amount, it is determined that there is cheating or error in the repayment, wherein the amount of game coins to be repaid in the game is calculated based on the position, type and number of game coins placed by each game participant on the gaming table and the game result.

[0251] In addition, the control device may have the following structure:

[0252] It is possible to determine the game coins recovered for each seat number based on the ID information of the RFIID of the recovered game coins determined by the game coin tray determination device and the ID information of the RFID of the game coins read by the game coin reading device, compare the determined ID or amount or number of the game coins with the ID or amount or number of the game coins to be recovered for each seat number, and determine whether they are consistent for each seat number, wherein the ID or amount or number of the game coins to be recovered for each seat number is determined based on the measurement results of the position, amount and number of the 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.

[0253] In addition, the control device can be structured as follows: in each game, it can determine the types distinguished according to the use or purpose of the game coins based on the RFID ID information of the game coins read by the game coin reading device, and store the amount placed according to each type of the game coins, or the recovered amount or the repaid amount according to each seat number.

[0254] Furthermore, the control device may be configured to store, for each seat number, the accumulated amount deposited for each type of the tokens, the accumulated amount collected, or the accumulated amount paid back during a plurality of games.

[0255] In addition, the type of the game coins can at least be a cash code, a transfer code, or a promotional code.

[0256] Furthermore, the control device may be configured to be able to identify an owner based on ID information of the transcode, and store a cumulative amount of deposits of the transcodes, a cumulative amount of returns, or a cumulative amount of repayments for each owner.

[0257] In addition, the game coin reading device reads the game coins for redemption placed on the game coin reading device according to each seat number,

[0258] The control device can be structured as follows: comparing the repayment amount determined based on the game result obtained by the game result determination device and the measurement results of the position, amount and number of game coins obtained based on the image analysis result of the image analysis device, and the amount of the game coins placed according to each seat number obtained based on the reading result of the game coin reading device, to determine and output whether the repayment amount is consistent or inconsistent.

[0259] In addition, the control device can be structured as follows: when the judgment result of the repayment amount is inconsistent, it can display inconsistency, and then, when the amount of the game coins placed on the game coin reading device for each seat number read by the game coin reading device changes, it can make a judgment again and output consistency or inconsistency again.

[0260] Furthermore, the control device may be configured to compare the amount of the tokens placed for redemption for each seat number with the increase or decrease in the token tray before and after redemption to determine whether there is a difference.

[0261] Furthermore, the coin reading device may include a payment confirmation area on the dealer's side disposed in the placement area for placing the coins for redemption.

[0262] In addition, a mechanism for identifying game participants using a facial recognition system or a player ID card may be provided.

[0263] The control device may be configured to associate the seat number with the information of the game participant identified by the game participant identification unit.

[0264] Furthermore, a display device is provided for performing a display based on the output of the control device.

[0265] In addition, the game table also has a side placement area.

[0266] The side placement area is provided adjacent to each of the placement areas for the seat numbers.

[0267] The game coin reading device can read at least one of the side placement areas.

[0268] The control device can be structured as follows: it can grasp the type and number of the game coins placed in at least one of the side placement areas based on the image analysis results of the image analysis device, determine whether the total amount or total number of game coins in the at least one side placement area obtained based on the image analysis results of the image analysis device is consistent with the total amount or total number of game coins in the side placement area obtained based on the reading results of the game coin reading device, and output a signal of the determination result.

[0269] In addition, another embodiment of the present invention is a management system for the following table games:

[0270] It has:

[0271] Game coins, which are attached with RFIDs that can be individually identified;

[0272] a game table for playing games using the game coins;

[0273] a game recording device for recording, by means of a camera, game coins placed by each game participant in a game played on the gaming table as images;

[0274] an image analysis device for performing image analysis on the recorded image of the gaming coin;

[0275] a coin reading device that reads the RFID attached to the coin placed by each game participant; and

[0276] A control device that grasps the image analysis result of the image analysis device and the reading result of the game coin reading device,

[0277] The gaming table has a placement area consisting of a player placement area, a banker placement area, and a side placement area.

[0278] The side placement area is provided adjacent to each of the placement areas for the seat numbers.

[0279] The game coin reading device can read at least one of the side placement areas.

[0280] The control device has the following structure: it can independently grasp the type and number of the game coins placed in at least one of the side placement areas based on the image analysis results of the image analysis device, and determine whether the total amount or total number of game coins in the at least one side placement area obtained based on the image analysis results of the image analysis device is consistent with the total amount or total number of game coins placed on the side obtained based on the reading results of the game coin reading device, and output a signal of the determination result.

[0281] Furthermore, the control device may be configured to output the side where the determination result is inconsistent.

[0282] In addition, the control device can also be structured as follows: when the total amount or total number of 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 game coins placed on each side obtained based on the image analysis result of the image analysis device, a signal can be generated, which indicates that the RFID attached to the game coins may be damaged, or the RFID may not be attached to the game coins.

[0283] In addition, the control device can also be structured as follows: when the total amount or total number of game coins in each of the side placement areas obtained based on the reading results of the game coin reading device is greater than the total amount or total number of game coins in each of the side placement areas obtained based on the image analysis results of the image analysis device, a signal can be generated, which indicates that there may be an error in the reading of the game coins by the image analysis device.

[0284] In addition, a database is provided for storing the ID of the RFID attached to the game coin.

[0285] The control device may be configured 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.

[0286] In addition, the control device can be structured as follows: it can determine the recovered game coins on each side based on the ID information of the RFID of the recovered game coins determined by the game coin tray determination device and the ID information of the RFID of the game coins read by the game coin reading device, compare the ID or amount or number of the game coins to be recovered in each side placement area determined as follows with the ID or amount or number of the game coins recovered in each side placement area, and determine the consistency or inconsistency of the recovered amount according to each side placement area, wherein the determination of the ID or amount or number of the game coins to be recovered in each side placement area is obtained based on the measurement results of the position, amount and number of the 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.

[0287] If a coin or a stack of coins to be paid out is within the area of a coin reader 25, the placed coin and the payout coin can be paired and associated with owner information without detecting that the coin has moved out of the area of the coin reader 25. That is, even if a coin or a stack of multiple coins 1001 is present within the area of a coin reader 25, the placed coin and the payout coin can be paired and associated with owner information based on information indicating that the payout coin has disappeared from the coin tray or information indicating that the coin has been read by the coin reader 25 on the table. Of course, the placed coin can also be identified based on information indicating that the coin has moved out of the area of the coin reader 25. The placed coin and the payout coin can be paired using some of the information about the coin removed from the coin tray, the coin placed in the placement area, and the coin removed from the area of the coin reader 25, thereby associating the payout coin's owner information with the placed coin. Alternatively, the ID of the gaming coin may be read by RFID, and the type and number and stack of the gaming coin may be identified by a camera.

[0288] In addition to the situation where a coin or a stack of coins to be paid out exists in the area of a coin reader 25 when the coin is placed, this also includes situations where multiple stacks of coins exist when the coin is placed, but only one stack of coins remains during the payment process. The remaining stack of coins can be paired with the payout coin and associated with the owner information. In this case, by treating the remaining stack of coins as coins placed by a member, the member's coins can be tracked. Preferably, for each coin reader (e.g., each player position), only one member player is allowed to place coins, while multiple non-member players are allowed to place coins. In the case where there is only one member player at each player position, since the coins and owners are associated with each other, the information of the member player assigned to each player position can be determined based on the information of the placed coin. In addition, if there is a rule that member players should place coins before non-member players, the coin placed first can be associated with the information of the member player assigned to the player position (e.g., sitting in player position 1), or this association can be confirmed. Membership cards can be used to assign member players to player positions.

[0289] The coin reading device 25 can be provided for each area, such as Player, Banker, Tie, Pair, etc. Alternatively, a larger coin reading device 25 can be provided for each player position, each divided area, or the entire table. The divided areas are formed by dividing the entire table into multiple areas, such as an area including player positions 1 to 3 and an area including player positions 4 to 6. In either case, the placed coin and the payout coin can be paired based on information such as information that the coin has been removed from the area of the coin reading device 25 (no longer read by the coin reading device 25), information on the ID of the payout coin that has disappeared from the coin tray, information on the ID of the payout coin placed in the placement area, and the like, thereby updating the owner information.
