[0043] (First Embodiment)

[0044] use Figure 1 The overall outline of the table game management system according to the first embodiment of the present invention will be described. Figure 1 1004 is a diagram showing the overall overview of the same system. The card game table 1004 has placement areas P1441, B1442, T1443, P.P1444, and B.P1445 set for each player position 1131 to 1135. In addition, a game coin configuration area 1025 is set at each player position, and a game coin reading device 1002 is provided to read the RFID of the game coin 1001 placed in the game coin configuration 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 with coins 1001 .

[0046] Furthermore, the control device 1003 is provided, which grasps the reading result of the RFID of the game token 1001 read by the game token reading device 1002.

[0047] At the beginning, the player who participates in the game places the game coin 1001 in the placement area in 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 grasps the information about the owner of the game coin 1001 associated with the ID information of the RFID on the database.

[0048] Based on the result of the game, when the casino wins, the dealer recovers the game coins 1001 placed by the loser and puts them into the game coin tray 1009. The RFID of the game coins 1001 in the game coin tray 1009 is grasped by the game coin reading device 1002, and the information that the owner of the game coins 1001 recovered by the casino is the casino is recorded in the database through the control device 1003.

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

[0050] When making a payment, the payment game coins 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 paid game coins is explained. Figure 2 This is a method of recording information related to the owner of the game coin 1001 when the game coin payment is paid to the winner.

[0052] When multiple players place game coins in the same player position, and there are 2 or more piles, the game coin reading device 1002 reads the game coins 1001 placed in the game coin configuration area 1025 together, so that in the game, it is not known which game coin 1001 belongs to which player, and the ID 1010 of the placed game coins is obtained. After the winning or losing result of the game is determined, when paying the winner, the dealer pays each player (each pile) from the game coin tray 1009. The game coins 1001 taken out from the game coin tray 1009 are placed in the game coin configuration area 1025. The game coin reading device 1002 reads the ID 1011 of the payment game coin placed in the game coin configuration area 1025.

[0053] The paid game coin 1001 is received by the winner together with the initially placed game coin 1001. At this time, the placed game coin and the paid game coin are moved outside the game coin configuration area 1025, so the IDs of the placed game coin and the paid game coin disappear from the reading result obtained by the game coin reading device 1002. Thus, the control device 1003 grasps which player the paid game coin is paid to by associating it with the information related to the owner of the placed game coin.

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

[0055] Based on the above, the owner of the game coin 1001 can be traced, and 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] In addition, 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 to be independent of each player position, and the token reading device 1002 may read the token independently, in addition to being configured according to each player position.

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

[0060] Furthermore, the desktop game management system can also be constructed by combining 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 dealing shoe that determines the winning or losing result of the game, etc., to utilize information with each other.

[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 1 shows a game coin 1 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 includes an area 21 where data cannot be rewritten and an area 22 where data can be rewritten.

[0063] The area 21 in which data cannot be rewritten stores information that does not change during the use of the game coin 1, or information that does not change, or information that cannot be changed as fixed information 3. Specifically, the production information, product information, casino information, amount information, serial number, etc. of the game coin 1 are stored as fixed information 3. The production information includes the date and manufacturing machine of the game coin, and the product information includes, for example, information indicating the game coin used in the VIP area of ​​the casino, information indicating the type of the game coin (for example, information indicating that it is a transcode), etc.

[0064] The area 21 where data cannot be rewritten can be a functionally non-writable area in the style of the RFID tag, or can be a locked area so that after necessary information is written in the writable area, data cannot be written again.

[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 place 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 may be encrypted. In addition, the fixed information 3 and the variable information 4 may 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 An example of the change information 4 stored in the game coin 1 is shown in the figure, and the movement of the game coin 1 can be grasped as follows. 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 a compensation for the placing winnings. Mr. B left the casino with the game coin 1 at 17:01 on the same day.

[0069] like Figure 4 As shown, the change information 4 can be configured to store only the latest information, or to store all the location-related information written. In addition, several of the multiple location-related information can be selected for storage. When several are selected for storage, multiple location-related information including at least the latest location-related information 220 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 mastered.

[0070] Next, the management system of the gaming coins 1 according to the present 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 the completion of manufacturing or the 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 game coins 1 shipped from the factory 6 are received and processed in the background 7 of the casino. In the background 7, the reading device 13 reads the change information 4 stored in the area 22 where data can be rewritten of the game coins 1. Based on the reading result, the management control device 15 determines whether the information 220 related to the location that should be written, that is, the information written in the factory 6, is written as the latest change information 4. If there is no write record in the factory 6, it is considered to be a game coin suspected of being improper, and an error signal is generated. Thus, the casino side can refuse to accept the game coin, or entrust the factory side to investigate. If there is no problem with the write record, the information 220 related to the location of the background is written into the area 22 of the RFID tag 2 where data can be rewritten by the writing device 14. When writing, the location information of the background 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 background can be recorded. In addition, the reading and writing of the game coins in the background 7 can be carried out together with the usual verification and activation operations of the game coins.

[0073] The game coin 1 that has completed the reception inspection in the background 7 is 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 of the game coin 1. Based on the reading result, the management control device 15 determines whether the information that should be written, that is, the information 220 related to the location that has been written in the background 7 is written as the latest change information 4. In addition, it can be checked at the same time whether the information indicating the factory 6 is written in the historical record of the change information 4. Similar to the aforementioned inspection in the background 7, the management control device 15 determines whether there is an abnormality in the historical record of the location information. If there is no problem with the reading result, the writing device 14 writes the information related to the location indicating the warehouse 8 or counter 9 into the area 22 where data can be rewritten.

[0074] The player purchases a game coin 1 at the counter 9. When the player purchases the game coin 1, the writing device 14 located at the counter 9 writes information indicating the time when the game coin was purchased and the change of the owner of the game coin from the casino to the guest as the change information 4. It can also be configured so that the player is identified and recorded by a facial recognition technology, a casino membership card, an ID card, or the like.

[0075] The player plays the game by using the purchased game coin 1 and placing the game coin 1 in the placement area 11 on the game table. The reading device 13 reads the location-related information 220 composed of date and time information 221, location and 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: a certain time has passed since the date of the last written use information at the game table or the information purchased at the counter, and the owner information 223 stored in the game coin 1 is different from the owner information 223 determined by facial recognition or ID card.

[0076] When there is no problem with the reading result, for the placed game coin 1, the writing device 14 writes the information 220 related to the location to the area 22 where data can be rewritten. The information 220 related to the location includes date and time information 221, location, event information 222, and owner information 223. At the game table, for example, the change information 4 including the player position number where the game coin 1 is placed and the player's information is written by the writing device 14. The player's information can be determined by an ID card or facial recognition. Usually, since several game coins 1 are placed in the placement area 11 in an overlapping manner, they are written together in an overlapping state.

[0077] When a player takes the game coin 1 out of the casino, the player exits the casino at the entrance 10. When exiting the casino, the reading device 14 reads the information 220 related to the location, and the management control device 15 determines whether the change information 4 is normal. In addition, at the entrance 10, the writing device 14 writes the change information 4 including the location indicating the exit, event information 222, and owner information 223.

[0078] When a player enters the casino from the casino side, if he / she brings in the game coins that he / she has taken out before, the information related to the location is read by the reading device 13, and the change information 4 is determined to be normal by the management control device. For example, for the game coins 1 that are temporarily taken out of the casino, if the owner when leaving the casino is different from the owner when entering the casino, the receiving behavior of the game coins outside the casino can be grasped.

[0079] In the case where the reading result of the reading device 13 is determined to be abnormal, the management control device 15 can output an alarm to the counter 9 or the entrance 10. When the owner of the game coin 1 exchanges at the counter 9 or exits from the entrance 10, he can refuse to exchange based on the alarm output by the management control device 15, or conduct an individual inspection when exiting. In addition, in the case where the judgment result is abnormal, the management control device 15 issues a warning to the dealer of each gaming table to interrupt the game, or issues a warning to the game table, and the game table manager can determine whether to interrupt the game or continue the game, or replace 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.

[0080] Similarly, the management control device 15 can read the change information 4 by the reading device 13 when exchanging at the counter, and determine the abnormality. Specifically, it can be determined as abnormal in the following cases: a certain time has passed since the date of the last written use information on the game table, the information exchanged at the counter, and the person who is different from the owner information 223 stored in the game coin 1 wants to exchange. In the case of determining that it is abnormal, the management control device 15 can output a warning and refuse to exchange the game coin 1 determined to be abnormal.

[0081] In the above description, although the reading device 13 performs reading and the management control device performs determination and then the writing device 14 performs writing, a configuration in which reading and writing are performed simultaneously may be adopted.

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

[0083] At the factory 6, when production is completed or when shipping, the RFID tag 2 is read and / or written. Production information and product information are written as fixed information 3, locked so as not to be rewritable as necessary, 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 a specified time.

[0086] At the counter 9, when the game coin 1 is moved from or to the warehouse 8, or when the game coin 1 is exchanged, the RFID tag 2 is read and / or written. When the exchange is performed at the counter 9, the place of exchange, event information 222, and information of the player who performed the exchange are written as owner information 223 of the change information 4. The 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 leaves the casino, the RFID tag 2 is read and / or written. For all the game coins 1 taken out of the casino by the player when leaving, the place and event information 222 indicating the taken out and the owner information 223 indicating the player who took out are written as the change information 4 and registered. Similarly, when entering the casino, the place and event information 222 indicating the brought in and the owner information 223 indicating the brought in player are written as the change information 4 and the game coins 1 brought into the casino are registered.

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

[0089] In the coin tray 12 , the RFID tag 2 is 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 payment area, and the RFID tag 2 can be read and / or written to the gaming coin 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 of determining whether there is an abnormality in the location-related information 220 obtained from the reading result of the reading device 13 at each location. As a determination of whether there is an abnormality, it can be determined whether there is any one of the following situations: the location-related information 220 has not been used for a predetermined time or longer since the last writing, or the location-related information that should have been written has not been written.

[0092] The case where the data has not been used for a predetermined period of time or longer since the last writing is any of the following.

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

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

[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 information related to the location that should be written is not written is any of the following situations:

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

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

[0099] 6) When exiting the amusement park, the 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 determination of whether it is abnormal:

[0101] 1) A person who is different from the final owner of the data stored in the area 22 where data can be rewritten exchanges the game coin 1 in the casino, or leaves 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 coin into the casino.

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

[0104] 1) A person who is different from the final owner of the game coin 1 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 person who is different from the person who purchased the game coin 1 at the counter 9;

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

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

[0108] Figure 8The database involved in other embodiments of the present invention is shown. The management system also has a database 17 that records the same fixed information 3 and variable information 4 in addition to the game coin 1. The management control device 15 can record the information in the database 17 based on the reading result of the reading device 13, and compare the fixed information 3 and variable information 4 stored in the game coin 1 with the information in the database to determine abnormalities.

[0109] In the RFID tag 2 of the present embodiment, the area that cannot be functionally written in the area 21 that cannot rewrite data may be a TID (tag number). After the necessary information is written in the area 21 that cannot rewrite data, the area locked so that data cannot be rewritten may be an EPC or a user area. The area 22 that can rewrite data may be an EPC (electronic product code) or a user area.

[0110] The reading device 13 and the writing device 14 can be changed in form according to the location. For example, in the factory 6, Figure 6 The device on the table shown has a box-shaped entrance and exit 10, and 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 a reading device 13 and a writing device 14. In addition, the game coins 1 can be read in a directly stacked state, or in a state stored in a game coin box, etc. In addition, the reading device 13 and the writing device 14 can be formed in one piece.

[0111] In the above embodiment, a case where a game coin has one RFID tag, and the single RFID tag has an area where data cannot be rewritten and an area where data can be rewritten is described. In this regard, the following form can also be considered: two RFID tags are placed in the game coin, one of which is locked on the basis of storing fixed information so that data cannot be rewritten, and the other RFID tag records variable information, so that data can be rewritten in advance.

[0112] However, in this case, the following problems may occur: when multiple game coins are read together, Fig. 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] In addition, generally speaking, since the larger the diameter of the RFID tag, the higher the reading accuracy, when the RFID tag is placed in the game coin, it is desired that the RFID tag has a diameter at least larger than the radius of the game coin, but since placing two RFID tags in the game coin will reduce the diameter of each RFID tag, 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 is reduced.

[0115] From the above aspects, it can be considered that implementation through 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 game tables according to an embodiment of the present invention. Fig. 9 As a diagram representing an overall overview of the same system, a management system for tabletop games in a gaming facility having multiple gaming tables 2004 comprises: a game recording device 2011, which records games played on the gaming tables 2004, including 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 result determination device 18 is, for example, a card issuing device 2003, which is a so-called electronic card shoe that has been used by those skilled in the art. It is structured so that the game rules are pre-programmed, the information of the issued card C is read, and the winning or losing of the game can be determined. For example, in a certain card game, the winning of B and the winning of P are basically determined by the face value of 2-3 cards, and the determination result (winning or losing result) 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 P (PLAYER) 441, B (BANKER) 442, T (TIE) 443, P.P444 and B.P445. 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. Fig. 9For example, two coins 1 are placed in T443 of seat number 5, and two coins 1 are placed in P441 of seat number 5, so as to play the game. A P-house card area 45 for placing the drawn P-house cards and a B-house card area 46 for placing the drawn B-house cards are also provided in the gaming table 2004.

[0120] The control device 2014 can grasp the position (P, B, T, PAIR) where each player 2006 places the game coin 1 in the placement area 2008, the type of the placed game coin 1 (the game coin 1 is divided into different amounts of value for each color) and the number of the game coin 1 by means of the camera 2002 and the image analysis device 2012. That is, for example, it can be grasped that two game coins 1 are placed in T443 of seat number 5 and two game coins are placed in P441.

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

[0122] like Fig.10 As shown, the control device 2014 grasps the total amount or total number of game coins 1 for each seat number based on the type and number of game coins 1 placed in each placement area of ​​each seat number based on the image analysis result of the image analysis device 2012, and compares it with the total amount or total number of game coins 1 for each seat number obtained based on the information of the RFID of the game coins 1 read by the game coin reading device 25 to determine whether they are consistent. Furthermore, the seat number determined to be inconsistent can be output, and the problematic seat number can be determined.

[0123] When 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. Fig.10In the example, for the game coin 1 placed in seat number 1, the total number of reads obtained by the image analysis device based on the image analysis device 2012 is 4, while the total number of reads obtained by the RFID reading of the game coin reading device 25 is 3. Therefore, it is considered that the RFID of one of the four game coins 1 placed in seat number 1 cannot 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 the image analysis device 2012 may be unable to read the game coins 1 due to reasons such as the game coins 1 entering the blind spot of the camera. Fig.10 In the example, for the game coin 1 placed at seat number 3, the total number of reads obtained by the image analysis device based on the image analysis device 2012 is 1, whereas the total number of reads obtained by the RFID reading of the game coin reading device 25 is 2. Therefore, it is considered that there may be a situation where there are two game coins 1 placed at seat number 3, but the image analysis device can only recognize one.

[0125] The ID information of the RFID attached to the game coin 1 is registered in the database of the casino, and records the information of production and delivery in the factory, reception, verification, and activation on the casino side. The control device 2014 can compare the information of the RFID read by the game coin reading device 25 with the information in the database to determine the authenticity of the game coin registered as the 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] In addition, the management system of the table game further includes a game participant identification mechanism using a facial recognition system or a player ID card, and the control device 2014 can associate the game participant information identified by the game participant identification mechanism with the seat number. The control device 2014 can store the deposit amount, repayment amount or collection amount, and winning and losing information stored for each seat number for each game participant. In addition, the information that the game participant has played multiple games at multiple game 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 been increased or decreased according to the amount of recovered lost game coins 1 placed by each player 2006 and the amount of payment 9W of the winning game coins to the winning player 2006W according to the winning result of the game. The game coin tray determination device can be set to use the camera 2002 to shoot the game coins 1 stored in the game coin tray 17 and grasp the total amount of game coins 1 in the game coin tray 17 based on the analysis of the image analysis device, or it can be set to be set to the game coin tray 17 by arranging an RFID reading device 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, information about how many and which type of game coins 1 are placed at which position (P, B, T, or PAIR) in the placement area 2008, 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 certain card game, the card issuing device 2003 reads the face value of the card C drawn in the game, thereby determining the winning or losing result of the game according to the rules of the card game. In addition, the camera 2002 is used to shoot the game table 2004, the image analysis device 2012 is used to analyze the image, and the control device 2014 compares the analysis result with the game rules to determine the winning or losing result of the game. In this case, the camera 2002, the image analysis device 2012, and the control device 2014 constitute a game result determination device. The information of which position (P, B, T, PP, BP) the player of each seat number 7 has placed and how many pieces of which type of game coins 1 can be obtained by shooting the game coins 1 placed in the placement area 2008 with the camera 2002 and analyzing the image for each play 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 lost game coins 1 and the repayment of 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 lost game coins 1 and the repayment of won game coins 1 is compared with the total amount of game coins 1 in the game coin tray 17 after the recovery of lost game coins 1 and the repayment of won game coins 1.

[0132] For example, the total amount of game coins 1 in the game coin tray 17 before the game starts is set to Bb, and the total amount of game coins 1 in the game coin tray 17 after the game ends and the recovery of lost game coins 1 and the repayment of won game coins 1 are completed is set to Ba. In addition, in this game, the total amount of all playing positions 7 of the game coins 1 placed in the P area is set to bp, the total amount of all playing positions 7 of the game coins 1 placed in the B area is set to bb, and the total amount of all playing positions 7 of the game coins 1 placed in the T area is set to bt. For example, in the case where the winning or losing result of the game is that B wins, Ba-Bb=bp-bb+bt should be established. Alternatively, 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 error in the recovery or repayment of game coins.

[0133] exist Fig.14A Detailed diagram of the coin tray of this embodiment is shown in FIG. Fig. 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 increase amount of the game coins 1L in the game (the 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 amount that should be and the actual amount, and determine whether there is a difference.

[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 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, 1W of game coins in the repayment game coin tray 172 can be used to ensure that the image analysis device 2012 and the control device 2014 have sufficient time to grasp the actual total amount of 1L of game coins in the recovered game coin tray 171 after recovery.

[0136] 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 game table 2004 and the winning or losing results of the game in 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 detection of the difference to the record of the image captured by the camera 2002. The operator on the casino side can find out the cause of the difference by confirming the image.

[0137] In the management system of the tabletop games of the present 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 positions, types and numbers of the game coins 1 placed by all the players 2006 in the game and the winning or losing result of the game obtained by the winning or losing result determination device. The expected 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 by the image analysis device 2012, and a determination is made as to whether there is a difference between the expected 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 game coins placed by the losing player.

[0139] The control device 2014 will add the total amount of game coins 1 in the game coin tray 17 before the settlement of each game, and the increase in the game coin tray 17 in the game obtained by the position, type and number of game coins 1 placed by the losing player, to obtain the total amount of game coins 1 in the game coin tray 17, and compare 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 expected total amount and the actual total amount, and the expected total amount 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 by means of the image analysis device 2012, and if it is determined that there is a difference between the expected total amount and the actual total amount, it is determined to be a payment error, and a payment error signal notifying the payment error is generated.

[0140] The game coin tray 17 is provided with a recovery game coin 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 recovery game coin tray 171 with the actual total amount of the game coins 1L in the recovery 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 recovery 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 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 time to the obtained image, or determine and reproduce 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 clearing at the end of the game by means of the image analysis device 2012, but the judgment after clearing in this case refers to the moment when any one of the following 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 the discard slot 42 of the table;

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

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

[0146] In addition, the control device 2014 is an artificial intelligence effective utilization type or deep learning structure as follows: it is able to grasp the position (position of P, B, or PAIR) and amount (type and number) of the game coins placed at each playing position 7 of the game table 2004, compare the winning and losing history of each player 2006 and the amount of game coins (amount won) obtained from the winning and losing results of each game with the statistical data of a large number of past (big data) games, and extract abnormal conditions (set by the casino). Typically, it is a device having the following artificial intelligence effective utilization type or deep learning structure control device 2014: the occurrence of a certain amount (1 million points) or the state in which the amount of game coins placed when losing is small and the amount of game coins placed when winning is large at the playing position 7 of a certain game table 2004 continues for multiple games, and compares this situation with the statistical data (big data, etc.) of past games, and can extract this as an abnormal situation.

[0147] Furthermore, the control device 2014 (integrated with the image analysis device 2012) of the management system of the table game is a structure capable of identifying individual players 2006 at the playing position 7 where abnormal conditions are extracted or at the playing position 7 where a winning amount of more than a prescribed amount is obtained. For the identification of such players 2006, the image analysis device 2012 obtains a facial image by extracting feature points, etc., and assigns an identity number (ID, etc.) to identify the player. In addition, the control device 2014 has a warning function to notify the other gaming table of the presence of the specific player when the specific player 2006 leaves the seat and sits at another gaming table. Specifically, the game table manager or the person in charge of each gaming table 2004 (which may also be the dealer) is notified to prevent more abnormal phenomena.

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

[0149] exist Fig.11 In Fig.12 as well as Fig.13 As shown in the detailed table, the game coin 1 is placed. Based on the analysis of the image analysis device 2012, the place (P, B, etc.) and the number (and amount) of the game coins 1 can be grasped. On the other hand, based on 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 collection, and thus the collected game coins 1 can be grasped. Figure 11 to Figure 13In the case where the game result is that B wins, according to the analysis results of the image analysis device 2012, it can be known that the two game coins placed on BP 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 grasp the total amount or total number of game coins 1 to be recovered for each seat number determined by using the game result obtained by the game result determination device and the detection result of the position, amount and number of game coins 1 obtained based on the image analysis result of the image analysis device. Therefore, the control device 2014 can compare the total amount or total number of game coins 1 recovered for each seat number determined based on RFID with the total amount or total number of game coins 1 to be recovered based on the image analysis result to determine whether they are consistent.

[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 "T2 pieces, B2 pieces", the game result is "B 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 at T are correctly recovered.

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

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

[0154] Transcodes are special game coins that can be purchased by specific members and cannot be exchanged. Transcodes are managed according to the amount purchased by each member. The amount of transcodes placed or recovered is stored based on the RFID information read by the game coin reading device 25, so that the amount of transcodes that a specific member should hold can be grasped.

[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. Fig.15As shown, in the case of making a repayment to the B family of seat number 2, the game coin 1 for repayment is placed in the game coin reading device 25 and read. Fig.15 The winning coin 1 placed by player B at seat number 2 is placed next to the coin. The control device 2014 can compare the repayment amount determined based on the game result obtained by the game result determination device and the measurement result of 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. Fig.16 In the example, the total number of game coins 1 to be paid for seat number 1 is 4, while the reading result of the game coin reading device 25 is 3, which is inconsistent. In the case of inconsistent repayment amounts, an inconsistent signal is output, and the dealer can re-place the game coins 1 for repayment based on the output signal. In the case of re-placing the game coins 1, a determination can be made again and the determination result can be output. The area where the game coins 1 for repayment are placed can be any position within the game coin reading device 25. In addition, if Fig.15 As shown, the payment confirmation area 26 can be configured on the dealer side of the placement area separately from the placement area. Fig.15 In the process, the game coin 1 for repayment is placed in 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 in B.

[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 implemented determination. The signal can be output in the form of being displayed on the display unit of the coin tray 17 or the display unit of the card issuing device 13, or the signal can be output by the game station manager or the backstage of the casino.

[0158] The game coin reading device 25 can be as follows Fig.17 As shown, all placement areas are treated as a read area for each seat number, or as Fig.18 As shown in FIG. 1 , for each seat, the P placement area and the B placement area are used as one reading area, and the T placement area, the P placement area, and the B placement area are used as one reading area. Fig.19 and Fig. 22As shown, each of the TP placement area, the PP placement area, and the side placement area of ​​the BP placement area may be regarded as one reading area.

[0159] Next, the token 1 used in the embodiment of the present invention will be described. Fig. 20 This is the appearance of the game coin 1 used in this system. Fig.21 The front cross-sectional view. The game coin 1 is formed into a multi-layer structure as follows: a plurality of plastic layers of different colors are stacked, with at least a coloring layer 101 in the middle, and white layers 102 or light-colored layers (although not shown in the figure, as long as they are layers lighter in color than the coloring layer 101) stacked on both sides of the coloring layer 101 in the middle. Fig. 20 As shown, a stripe pattern in the stacking direction is formed on the side, and by changing the color of the coloring 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 Fig.21 As shown by the colored multiple layers (in Fig.21 Because the colored layers (in Fig.21 There are 3 layers in the middle) are heat-pressed and bonded to each other, so that Fig.21 As shown, the three-layer structure is not visible. Fig.21 In the three layers of the coloring layer 101, a part of the hollow portion B is provided in the middle layer, 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 is a detailed description of the method by which the image analysis device 2012 analyzes the game coin 1. The image analysis device 2012 performs image analysis on the image recorded by the recording device 11, and identifies at least two colors, namely, a specific color 121 at least partially attached to the game coin 1, and a 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 a coloring layer 101, attached to the side of the game coin 1 in the circumferential direction, or 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 a color attached to a position different from the specific color 121 in the game coin 1.

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

[0164] 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 uses 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 for learning through artificial teaching, thereby creating 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 specific color 121 and the reference color R can be irradiated under the same illumination, thereby obtaining a relative relationship between the specific color 121 and the reference color R. For example, this relative relationship can be used for the recognition of 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 also has the following structure: by performing image analysis on the peripheral image of the specified range extracted around the center line C (for example, a range of 8 pixels orthogonal to the center line with the center line as the center, etc.), the specific color 121 and at least two colors of the reference color R different from the specific color 121 in the peripheral image are recognized. In addition, when performing image analysis on the peripheral image of the specified range extracted around the center line C, the image can be analyzed directly, or it can be analyzed after performing image processing such as color emphasis and noise removal, so that the specific color 121 can be more easily recognized.

[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 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 by performing image analysis on the peripheral image within a specified range centered on the center line C, 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 issuing device displays the winning or losing result of the game,

[0170] 2) After each game is over, during the period when the dealer collects the game coins placed by the losers among the game participants, whether there is no 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 has paid 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 game coins, or the movement of the hands and the movement of 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 certain card game, and as a characteristic function of the present invention, it determines whether cheating that violates the rules is not performed. That is,

[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 when 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 a person other than the dealer 2005 (winner or loser) has added the won game coins 1W or replaced the game coins 1 on the winning side during the period when the dealer 2005 recovers the game coins 1 placed by the loser among the game participants, or whether the game coins 1 have not been placed.

[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 makes the display light 13 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] In addition, in the above-mentioned embodiment, 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, the image analysis device 2012 and the control device 2014 can be a scale-invariant feature transform (SIFT; Scale-Invariant Feature Transform) algorithm, a convolutional neural network (CNN; Convolutional Neutral Network), deep learning (deep learning), machine learning (machine learning), or the same method for image analysis and the above-mentioned various controls. These technologies are technologies for performing image recognition on a camera image to identify the object included in the image. In recent years, in particular, deep learning technology that multi-layers a neural network is used to recognize objects with high accuracy. This deep learning technology generally recognizes objects with high accuracy by overlapping layers across multiple stages in the intermediate layer between the input layer and the output layer of the neural network. Among these deep learning technologies, convolutional neural networks in particular have attracted attention because they have higher performance than recognizing objects based on existing image feature quantities.

[0182] In the convolutional neural network, the recognition target image with a label is learned, and the main object included in the recognition target image is recognized. When there are multiple main objects in the learning image, they are specified by a region rectangle, and the image corresponding to the specified region is labeled and learned. Furthermore, in the convolutional neural network, the main object in the image and the position of the object can also be determined.

[0183] If the convolutional neural network is further explained, in the object recognition process, the candidate area is extracted based on the local features by performing edge extraction processing on the recognition object image, and the candidate area is input into the convolutional neural network, and classification is performed based on the extracted feature vector to obtain the candidate area with the highest credibility as the recognition result. The so-called credibility is a quantity that indicates how much the similarity between a certain image area and the main body of the image learned together with the label is relatively higher than other levels of similarity.

[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.

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

[0272] A game table, which is used to play games using the game coins;

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

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

[0275] a game coin reading device that reads the RFID attached to the game 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 game table has a placement area consisting of a P placement area, a B 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 together.

[0280] The control device has the following structure: it is able to independently grasp the type and number of the game coins placed in at least one of the side placement areas based on the image analysis results of the image analysis device, and to 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 reading the game coins by the image analysis device.

[0284] In addition, a database is provided, which stores 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 placement 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 game result obtained by the game result determination device and the measurement results of the position, amount and number of the game coins obtained based on the image analysis results of the image analysis device.

[0287] If there is a game coin or a stack of game coins to which game coins are to be paid in the area of ​​a game coin reading device 25, the placed game coin and the paid game coin can be paired and associated with the owner information without detecting that the game coin is moved out of the area of ​​the game coin reading device 25. That is, in the case where there is a game coin or a stack of game coins 1001 in the area of ​​a game coin reading device 25, even if the game coin is not detected to be moved out of the area of ​​the game coin reading device 25, the game coin can be paired with the payment game coin and associated with the owner information based on the information that the payment game coin disappears from the game coin tray or the information that the game coin is read by the game coin reading device 25 on the table. Of course, the placed game coin can be identified based on the information that the game coin has moved out of the area of ​​the game coin reading device 25, and the placed game coin and the payment game coin can be paired by using some of the information of the game coin taken out of the game coin tray, the information of the game coin placed in the placement area, and the information of the game coin moved out of the area of ​​the game coin reading device 25, so as to associate the information of the owner of the payment game coin based on the owner information of the placed game 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 the area of ​​a coin reading device 25, there is a coin or a pile of coins to which coins are to be paid, in addition to the situation that there is a coin or a pile of coins to which coins are to be paid in the area when the coins are placed, there is also a situation that there are multiple piles of coins but only one pile of coins is left in the process of payment when the coins are placed. Only the remaining pile of coins can be paired with the payment coins to be associated with the owner information. In this case, by using the remaining pile of coins as the coins placed by the member, it is possible to ensure that the coins of the member are tracked. Preferably, for each coin reading device (e.g., each player position), only one member player is allowed to place coins and multiple non-member players are allowed to place coins. In the case where there is a member player in each player position, since the coins and the owner are associated with each other, the information of the member players assigned to each player position can be determined based on the information of placing coins. In addition, if there is a rule that the member player should place coins before the non-member player, the coin placed first can be associated with the information of the member player assigned to the player position (e.g., sitting in the 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 may be provided for each area of ​​P, B, T, PAIR, etc., or a larger coin reading device 25 may be provided for each player position, for each divided area, or for the entire table. The divided area is an area formed by dividing the entire table into a plurality of areas, such as an area including player positions 1 to 3 and an area including player positions 4 to 6. In any case, the placed coins and the paid coins may be paired based on information that the coins have been moved out of the area of ​​the coin reading device 25 (the coins are no longer read by the coin reading device 25), information on the ID of the paid coins that have disappeared from the coin tray, information on the ID of the paid coins placed in the placement area, etc., thereby updating the owner information.
