Description

[Technical field]

[0001] The present invention relates to a management system for managing gaming chips at a game table. [Background technology]

[0002] At the game table, games are played using gaming chips. Players place bets by placing gaming chips in the betting area of ​​the game table. A player who wins a game receives gaming chips from the dealer, and a player who loses a game has their gaming chips collected by the dealer. A chip tray is provided in front of the dealer. The dealer pays out gaming chips from the chip tray to players who win a game, and places gaming chips collected from players who lose in the chip tray.

[0003] Attempts have been made to electronically grasp gaming chip transactions at such gaming tables. For this purpose, an RFID tag storing information capable of identifying the value of the gaming chip is embedded in the gaming chip, and an RFID antenna for reading this RFID tag is provided in the betting area and the chip tray. By reading the RFID tag of the gaming chip with these antennas, the amount bet, the amount collected, the amount paid out, etc. can be grasped. Furthermore, by linking with a means for determining the game result (for example, in the case of baccarat, the game result can be determined by reading the rank of the cards dealt in the shoe), it can be determined whether the amount that should be collected has been collected or the amount that should be paid out has been paid out, and fraud or errors in collecting or paying out can be detected.

[0004] Furthermore, by storing the chip ID in the RFID tag and associating the chip ID with information on its owner (casino, player ID) in a database, it is possible to trace the gaming chip. In tracing, the owner associated with the chip ID in the database is updated every time the owner of the gaming chip is changed.

[0005] In addition, the above fraud and mistakes can also be detected by photographing the gaming chips with a camera and recognizing the type (value) of the gaming chips in the betting area or chip tray through image recognition using a neural network, etc. Traceability can also be achieved by writing the chip ID on the side of the gaming chip and recognizing the chip ID through image recognition.

[0006] Furthermore, nowadays, by performing pose tracking and facial recognition of a player who operates gaming chips to play a game at a game table, it is possible to associate the player, the gaming chips, and the betting action. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] [First embodiment: Management of gaming chips throughout the casino] Gaming chips are brought into the casino through a cage in the casino, and gaming chips to be discarded are also taken out from the cage. Conventional gaming chip tracing systems cannot necessarily monitor the movement of all gaming chips in the casino, including the movement of gaming chips inside the cage and between the cage and each location in the casino.

[0032] Therefore, this embodiment describes a cage system for monitoring the movement of gaming chips in a cage and between the cage and each location within a casino, and a gaming chip management system that includes the cage system and manages gaming chips within the casino.

[0033] The cage system of this embodiment is a cage system that manages the movement of gaming chips in a cage of a casino hall, the cage is divided into a plurality of locations including a cashier, the gaming chip has an RFID tag that stores a chip ID, and the cage system is configured to include a first reading means that reads the chip ID from the RFID tag of the gaming chip that moves between the plurality of locations, a second reading means that reads the chip ID from the RFID tag of the gaming chip that leaves the cage to the casino hall, and a recording means that records the chip ID read by the first reading means and the second reading means as the movement history of the gaming chip. With this configuration, the movement of the gaming chips in the cage can be managed.

[0034] In the cage system described above, the recording means may record the destination and / or origin of the movement together with the chip ID in the movement history. With this configuration, it is possible to know whether the movement is being performed accurately.

[0035] The cage system may further include a management unit for determining whether or not a movement is appropriate based on the movement history. With this configuration, inappropriate movements can be detected.

[0036] In the above cage system, the management means may record in the recording means that a gaming chip having a movement history that does not match a predetermined possibility of a movement history is fraudulent or suspected of fraud.

[0037] The cage system may further include a third reader for reading the chip ID from the RFID tag of the gaming chip entering the cage from the casino hall. With this configuration, the gaming chips in the cage can be completely managed.

[0038] In the cage system described above, the management means may issue an alert or record when the destination of the gaming chip leaving the casino hall is recorded in the movement history of the gaming chip leaving the casino hall and the gaming chip is not received at the destination. With this configuration, it is possible to detect that the movement from the cage to a predetermined location in the casino hall has not been completed normally.

[0039] In the cage system described above, the management means may issue the alert or record the event when the gaming chip is not received at the destination within a predetermined time. With this configuration, it is possible to determine that an abnormality exists when the movement is not completed within a predetermined time.

[0040] The gaming chip management system of this embodiment has a configuration including any one of the cage systems described above and a fourth reading means that is installed on a game table and reads the chip ID from the RFID tag of the gaming chip. With this configuration, gaming chips in a casino hall including a cage can be managed.

[0041] In the gaming chip management system, the management means may calculate the total amount of the gaming chips held by the players in the casino hall. With this configuration, the total amount of the casino's debts can be grasped in real time.

[0042] In the gaming chip management system, the management means may record date and time information in the movement history. With this configuration, the movement history can be recorded in more detail.

[0043] In the gaming chip management system described above, the management means may detect any suspicious movement of the gaming chips based on the date and time information. With this configuration, various suspicious movements can be detected.

[0044] In the gaming chip management system, the management means may record information about the staff involved in the movement in the movement history. With this configuration, if an inappropriate movement occurs, the staff involved can be identified.

[0045] Hereinafter, a cage system and a gaming chip management system according to the present embodiment will be described in detail with reference to the drawings.

[0046] FIG. 1 is a schematic diagram showing the overall configuration of a casino according to a first embodiment of the present invention. A casino hall 1 is equipped with a cage 10 and a plurality of game tables 42-45. The floor on which the game tables 42-45 are equipped may be divided into a VIP floor and a public floor. The cage 10 is a room that only security staff can enter. The cage 10 is divided into a vault 11, a main bank room 12, an F / C bank room 13, and a cashier room 14.

[0047] The vault 11 is provided with a gate 21 leading to the outside of the cage 10, a gate 22 is provided between the vault 11 and the main bank room 12, a gate 23 is provided between the main bank room 12 and the F / C bank room 13, a gate 25 is provided between the main bank room 12 and the cashier room 14, and the F / C bank room 13 is provided with a gate 24 leading to the casino hall 1 in which game tables 42-45 are placed. The cashier room 14 is provided with gates (windows) 26-28 leading to the casino hall 1. Each of the gates 21-25 may allow people and gaming chips to pass through, or only gaming chips may pass through, and a door for people to enter and exit may be provided separately from the gate. The windows 26-28 are open to an extent that gaming chips can be exchanged for cash.

[0048] A vault staff member 31 is stationed in the vault 11, a main bank staff member 32 is stationed in the main bank room 12, an F / C bank staff member 33 is stationed in the F / C bank room 13, and cashier staff members 34-36 are stationed in the cashier room 14 corresponding to the windows 26-28.

[0049] In the casino hall 1, game tables 42-45 are installed, and one dealer 52-55 is arranged at each of the game tables 42-45. Although only four game tables are shown in the example of FIG. 1, in reality, more game tables are arranged in the casino hall 1. In addition, a pit manager 56 is arranged for each of the adjacent game tables 42.

[0050] In the example of FIG. 1, there are players 61 to 69 in the casino hall 1. The players in the casino hall 1 can purchase gaming chips or exchange gaming chips for cash through any of the windows 26 to 28, as in the case of the player 61 shown in FIG. 1. The players who have purchased gaming chips in the cage 10 can bet gaming chips at the game tables 42 to 45 and enjoy games. If the player loses a game, the dealer collects the gaming chips from the player, and if the player wins a game, the dealer pays out the gaming chips according to the game rules and the bet amount. In this way, the gaming chips held by the players increase or decrease depending on the game. If the player runs out of gaming chips, he or she can purchase gaming chips again (buy-in) in the cage 10. Furthermore, when the player finishes playing, he or she can exchange gaming chips for cash (buy-out) in the cage 10.

[0051] At the game tables 42 to 45, gaming chips are collected from players who lose a game, and gaming chips are paid to players who win a game. As a result, the number of gaming chips held by the dealer (casino) at the game table increases or decreases. When gaming chips are insufficient at the game table, the gaming chip transport staff 51 receives gaming chips from the gate 24 of the F / C bank room 13, transports them to the game table, and replenishes them at the game table. Replenishing gaming chips at the game table in this manner is also called "fill." Also, when gaming chips are excessive at the game table, the gaming chip transport staff 51 transports gaming chips from the game table to the cage 10, and the gaming chips are stored in the F / C bank room 13 through the gate 24. Returning gaming chips from the game table to the cage 10 in this manner is also called "credit."

[0052] In addition, when managing the movement history of gaming chips in the casino hall 1, the movement source, movement destination, and places that may be between them are hereinafter referred to as locations. In the example of Figure 1, for example, each room and each game table in the cage 10 is called a location.

[0053] FIG. 2 is a perspective view of a gaming chip according to a first embodiment of the present invention. FIG. 2 shows a $100 gaming chip. The gaming chip 70 has a disk shape, and the face value ("$100" in the case of FIG. 1) is printed on both sides. Multiple layers are laminated in the thickness direction in the order of a white layer, a colored layer, and a white layer, and the sides have a striped pattern with a colored layer sandwiched between white layers. The color of the colored layer varies depending on the face value, so the face value of the chip can be determined by distinguishing the color of the colored layer.

[0054] An RFID tag 71 is built into the gaming chip 70. The RFID tag 71 stores information on the chip ID and face value of the chip. The RFID tag 71 may be writable, and in this case, the RFID tag 71 may record information on the current location or owner of the gaming chip, and may also record the history of past locations or owners. The gaming chip 70 may be formed by pressing a plurality of plate materials together, or may be formed by resin molding.

[0055] 3 is a block diagram showing the configuration of a chip management system according to a first embodiment of the present invention. The chip management system 1000 includes a cage system 501 and a plurality of table systems 502. A table system 502 is provided for each game table. The cage system 501 includes a chip management computer 100 and a chip management database 101 for managing chips in the cage 10 and the casino hall 1 in an integrated manner.

[0056] The cage system 501 also includes a vault computer 111 installed in the vault 11, and a vault card reader 112 and a vault chip reader 113 connected thereto. The cage system 501 also includes a main bank computer 121 installed in the main bank room 12, and a main bank card reader 122 and a main bank chip reader 123 connected thereto. The cage system 501 also includes an F / C bank computer 131 installed in the F / C bank room 13, and an F / C bank card reader 132 and an F / C bank chip reader 133 connected thereto. The cage system 501 also includes a cashier computer 141 installed in the cashier room 14 corresponding to each of the windows 26 to 28, and a cashier card reader 142 and a cashier chip reader 143 connected thereto.

[0057] The table system 502 includes a table computer 151, and a table card reader 152, a collection table chip reader 1531, a payout table chip reader 1532, a chip tray chip reader 154, and a plurality of bet area chip readers 155 connected thereto. Although only one table system 502 is shown in FIG. 3, a plurality of table systems 502 are provided corresponding to a plurality of game tables. The above-mentioned "reader" includes an antenna and a reading device that controls the antenna to transmit radio waves to an RFID tag and obtains information on the RFID tag by decoding the signal received by the antenna.

[0058] The vault computer 111, the main bank computer 121, the F / C bank computer 131, the cashier computer 141, the table computer 151, and the chip management database 101 are each connected to the chip management computer 100. The chip management computer 100, the other computers, and the chip management database 101 may be connected to each other via a local network by wire or wirelessly. Alternatively, the chip management computer 100 and the chip management database 101 may be installed on a wide area network (e.g., the Internet) and connected to other computers via the wide area network. In other words, the chip management computer 100 and the chip management database 101 may be installed in the cloud, not in the casino.

[0059] An input device (not shown) is connected to each of the computers 100, 111, 121, 131, 141, and 151 to receive operational input from the corresponding staff. The input device is, for example, a keyboard, a mouse, a button, a touch pad, a touch panel, or a voice input device. Note that the functions of each computer may be consolidated in the chip management computer 100, leaving only these input devices and communication devices at the corresponding locations. In this case, various signals (for example, input signals input to the input device, signals read by the chip reader, etc.) may be transmitted directly between the input devices, card readers, and chip readers at each location and the chip management computer 100.

[0060] The card readers 112, 122, 132, 142, 152 at each location read the staff ID or player ID from the ID card held by the staff or player. Specifically, the vault card reader 112, main bank card reader 122, and F / C bank card reader 132 read the staff ID from the ID card of the corresponding staff, and the cashier card reader 142 reads the staff ID from the ID card of the cashier staff, and also reads the player ID of the player who purchases gaming chips at the cashier or redeems gaming chips for cash. Also, the table card reader 152 reads the staff ID of the corresponding dealer, and reads the player ID of the player who will play.

[0061] The chip readers 113, 123, 133, 143, 153, 155 at each location read information from the RFID tag 71 of the gaming chip 70 and write information to the RFID tag 71. In particular, each chip reader 113, 123, 133, 143, 153 reads the RFID tag 71 when the gaming chip 70 moves from another location to the location in question and when the gaming chip moves from the location to another location (i.e., when the gaming chip 70 moves away from the location in question).

[0062] Fig. 4 is a schematic diagram showing the configuration of a game table according to the first embodiment of the present invention. Fig. 4 illustrates a game table 42. The game table 42 is provided with a plurality of play positions. The game table 42 is provided with a plurality of bet areas corresponding to the plurality of play positions on the table surface, a chip tray for accommodating dealer chips, a dealer area for reading and writing information to the RFID tag 71 of the gaming chip 70, and an ID card area for reading the ID cards of the dealer and the player.

[0063] The chip tray is provided with a chip tray antenna 514 for reading the RFID tag 71 of the gaming chip 70 accommodated therein. Each of the multiple betting areas is provided with betting area antennas 515a to 515e inside the table surface for reading the RFID tag 71 of the gaming chip 70 placed therein. In the dealer area, a collecting dealer antenna 5131 and a paying dealer antenna 5132 for reading the RFID tag 71 of the gaming chip 70 placed therein are provided inside the table surface. In the ID card area, an ID card antenna 512 is provided inside the table surface.

[0064] Each of the antennas 512 to 515 is connected to the table computer 151 and transmits the read signal to the table computer 151. The table computer 151 obtains various information stored in the RFID tag 71 or the ID card by decoding the signal from each antenna.

[0065] Staff members at each location begin work after having their card IDs read by the corresponding card readers. The computer at each location transmits the read staff ID and the date and time to the tip management computer 100. The tip management computer 100 stores the staff IDs read by the card readers at each location in the tip management database 101 together with information on the location and date and time.

[0066] The chip management database 101 stores a player table, a chip table, a game table table, a staff table, and a movement history table. The player table stores registration information of the player. The player table stores a player ID, various player attributes, and player status such as VIP, suspect, and blacklist for each player. The chip table stores a chip ID, face value, type, manufacturing information, and chip status such as valid, missing, stolen, and invalid. The game table table stores a table ID, game type, and the like. The staff table stores a staff ID, various staff attributes, and the like. The movement history table stores the location or holder history of the gaming chip 70.

[0067] (Gaming chip movement management) Fig. 5 is a diagram showing the manner of movement of gaming chips according to the first embodiment of the present invention. As shown in Fig. 5, each location except the vault may have multiple sources of movement when gaming chips enter, and may have multiple destinations when gaming chips leave. The chip management system of this embodiment recognizes these movements. To this end, the following several methods can be adopted.

[0068] (First Method) In the first method, when a gaming chip 70 enters a computer at each location, the computer at that location specifies its origin and reports this specification to the chip management computer 100 together with the chip ID of the gaming chip 70 that entered, and when a gaming chip 70 leaves a location, information on that location, i.e., the origin, and the chip ID of the gaming chip 70 are reported to the chip management computer 100.

[0069] For example, when the gaming chip 70 moves from the main bank chamber 12 to the F / C bank chamber 13, the main bank computer 121 reads the chip ID of the gaming chip 70 with the main bank chip reader 123, and reports to the chip management computer 100 that the gaming chip 70 is moving out of the main bank chamber 12 together with the read chip ID. The chip management computer 100 updates the chip management database 101 in response to this report.

[0070] Then, in the F / C bank room 13 which receives the gaming chip 70 from the main bank room 12, the F / C bank staff 33 operates an input device of the F / C bank computer 131 to input a designation that the gaming chip 70 is the gaming chip 70 which came from the main bank room 12 (the source of movement), and reads the chip ID of the gaming chip 70 with the F / C bank chip reader 133. The F / C bank computer 131 reports to the chip management computer 100 the read chip ID and a designation that the source of movement is the main bank room 12. The chip management computer 100 updates the chip management database 101 in response to this report.

[0071] 6 is a diagram showing an example of data in the chip management database updated by the first method of gaming chip movement management according to the first embodiment of the present invention. The example in FIG. 6 shows the movement history of a gaming chip 70 with a chip ID of "24825". The chip management database 101 stores, as information on the movement history of the gaming chip 70, the chip ID 601 of the gaming chip, entry / exit information 602, movement origin information 603, movement destination information 604, and date / time 605.

[0072] According to the first method, as shown in FIG. 6, for gaming chips 70 leaving a location, information on their origin is obtained (history H61), and for gaming chips 70 entering a location, information on their origin and destination is obtained (history H62). Therefore, based on history H61 and history H62, it can be confirmed that the gaming chips 70 have indeed left the main bank chamber 12 and been received in the F / C bank chamber 13.

[0073] (Second Method) In the second method, when a gaming chip 70 is sent out, the computer at each location specifies its destination and reports the specification to the chip management computer 100 together with the chip ID of the gaming chip 70 going out, and when a gaming chip 70 is received at each location, information on the location, i.e., the destination, and the chip ID of the gaming chip 70 are reported to the chip management computer 100.

[0074] For example, when gaming chips 70 are moved (credits) from table-4 to the F / C bank room 13, the dealer reads the chip ID of the gaming chip 70 with the table chip reader 153 of the game table, and operates the input device of the table computer 151 to specify the F / C bank room 13 as the destination (specify credits). The table computer 151 reports this chip ID, the F / C bank room 13 as the destination, and the table ID of table-4 as the source to the chip management computer 100. The chip management computer 100 updates the chip management database 101 in response to this report.

[0075] When the gaming chip 70 is received at the destination F / C bank room 13, the F / C bank staff 33 reads the chip ID of this gaming chip 70 with the F / C bank chip reader 133. The F / C bank computer 131 reports the read chip ID and the fact that the gaming chip 70 will be entering the F / C bank room 13 to the chip management computer 100. The chip management computer 100 updates the chip management database 101 in response to this report.

[0076] 7 is a diagram showing an example of data in the chip management database updated by the second method of gaming chip movement management according to the first embodiment of the present invention. The example in FIG. 7 also shows the movement history of a gaming chip 70 with a chip ID of "24825". The chip management database 101 stores, as information on the movement history of the gaming chip 70, the chip ID 601, entry / exit information 602, movement origin information 603, movement destination information 604, and date / time 605 of the gaming chip.

[0077] According to the second method, as shown in FIG. 7, for gaming chips 70 leaving a location, information on their origin and destination is obtained (history H71), and for gaming chips 70 entering a location, information on their destination is obtained (history H72). Based on history H71 and history H72, it can be confirmed that the gaming chips 70 have indeed left table-4 and been received in the F / C bank room 13.

[0078] (Third Method) The third method is a combination of the first and second methods. That is, in the computer of each location, when the gaming chips 70 come in, the source of the gaming chips 70 is designated, and when the gaming chips 70 go out, the destination of the gaming chips 70 is designated.

[0079] (Fourth Method) In the fourth method, the staff at each location uses an input device of the computer at each location to specify whether the gaming chip 70 is entering or leaving, and reports the specification together with the chip ID of the gaming chip 70 read by a chip reader to the chip management computer 100. The chip management computer 100 updates the entry / exit information and location information in the chip management database 101 based on this report.

[0080] 8 is a diagram showing an example of data in the chip management database updated by the fourth method of gaming chip movement management according to the first embodiment of the present invention. The chip management database 101 stores information on the movement history of the gaming chip 70, such as the chip ID 601, entry / exit information 602, location information 606, and date / time 605 of the gaming chip.

[0081] According to the fourth method, as shown in FIG. 8, entry / exit information 602 and location information 606 are recorded, so that it is possible to confirm that the gaming chip 70 has indeed left the vault 11 and been received in the main bank room 12 based on the history H81 and the history H82.

[0082] (5th method) In the fifth method, only location information is recorded. That is, when the gaming chip 70 is in the location, the staff at each location reads the chip ID of the gaming chip 70 with the chip reader at that location and reports it to the chip management computer 100. The chip management computer 100 updates the chip management database 101 in response to this report. The staff at each location may read the chip ID when the gaming chip 70 moves to that location, may read the chip ID when the gaming chip 70 moves from that location, or may read the chip ID at any timing.

[0083] 9 is a diagram showing an example of data of the chip management database updated by the fifth method of gaming chip movement management according to the first embodiment of the present invention. The chip management database 101 stores the chip ID 601, location information 606, and date and time 605 of the gaming chip as information of the movement history of the gaming chip 70.

[0084] According to the fifth method, location information 606 is also recorded as shown in FIG. 9, so that it is possible to confirm that the gaming chip 70 has indeed left the vault 11 and been received in the main bank room 12 based on the history H91 and the history H92.

[0085] It may be possible to determine which of the above-mentioned first to fifth methods is to be used for each combination of the source and destination. For example, the fourth or fifth method may be used for the movement of the gaming chips 70 within the cage 10, the second method in which the destination is designated at the source may be used for the movement from the F / C bank chamber 13 to the game table, and the first method in which the source is designated at the destination may be used for the movement from the game table to the F / C bank chamber 13.

[0086] (Purchases and redemptions at the cashier) Furthermore, when gaming chips 70 are transferred from the cashier room 14 to a player (when a player purchases gaming chips 70 at the cashier), the cashier computer 141 reads the chip ID of the gaming chip 70 with the cashier chip reader 143, reads the player ID from the player's ID card with the cashier card reader 142, and reports the read chip ID together with the designation of the player to whom the chips are to be transferred to the chip management computer 100. The chip management computer 100 updates the chip management database 101 in response to this report.

[0087] Then, when the gaming chips 70 are transferred from the player to the cashier room 14 (the player exchanges the gaming chips 70 for cash at the cashier), the cashier computer 141 reads the chip ID of the gaming chips 70 with the cashier chip reader 143, reads the player ID from the player's ID card with the cashier card reader 142, and reports the read chip ID together with the designation of the player from whom the chips were transferred to the chip management computer 100. The chip management computer 100 updates the chip management database 101 in response to this report.

[0088] Fig. 10 is a diagram showing an example of data of the chip management database updated by the fourth method of gaming chip movement management according to the first embodiment of the present invention. In the example of Fig. 10, player 5 purchases gaming chips 70 at cashier 2 (history H101, H102), and then player 5 exchanges the gaming chips 70 for cash at cashier 3 (history H103, H104). Note that when the first to third methods are used, the receipt / withdrawal information 602 may be set to N / A, and only the information of the transfer source (cashier) and transfer destination (player) may be recorded.

[0089] Also, for example, at the cashier, when the cashier staff receives a gaming chip 70 from a player, the cashier staff may specify that they will receive the gaming chip 70 and then use the cashier chip reader 143 to read the chip ID of the gaming chip 70, and when the cashier staff hands the gaming chip 70 over to the player, the cashier staff may specify that they will hand the gaming chip over and then use the cashier chip reader 143 to read the chip ID of the gaming chip 70.

[0090] This makes it possible to use one chip reader and clearly determine whether the gaming chip 70 whose chip ID has been read by that chip reader is entering or leaving that location. Also, when exchanging chips, it is possible to clearly distinguish between the gaming chip 70 received from the player and the gaming chip 70 given to the player and to specify the chip ID using the chip reader.

[0091] (Collection and withdrawal) A player who has purchased gaming chips 70 can play a game at a game table. At this time, at the game table, first, the table card reader 152 equipped with the ID card antenna 512 reads the player's ID card. When the table card reader 152 reads the player's ID card, the play position of the player is specified. This makes it possible to recognize which player is in which betting area. Note that the betting area antennas 515a to 515e may be one or more antennas that group multiple betting areas together as one betting area without distinguishing between the player positions, and read the gaming chips 70 placed in the one betting area. Also, the betting area antenna may not be provided.

[0092] When a player loses a game at a game table, the gaming chips 70 that he or she bets are collected. In this case, the chip tray antenna 514 reads the chip IDs of the gaming chips 70 stored in the chip tray before collection, and reads the chip IDs of the gaming chips 70 stored in the chip tray after collection. The table computer 151 compares the chip IDs of the chip tray before and after collection to recognize the chip IDs of the gaming chips 70 newly brought to the chip tray (i.e., collected from the player).

[0093] The table computer 151 reports to the chip management computer 100 the chip ID read by the chip tray antenna 514 regarding the gaming chips 70 collected from the player, together with a designation that the gaming chips 70 are to be moved to the chip tray of the game table. The chip management computer 100 updates the chip management database 101 in response to this report.

[0094] In addition, when the table computer 151 can determine whether each gaming chip 70 betted should be collected by recognizing the chip ID of the gaming chip 70 and the game result using the bet area antennas 515a to 515e, and when it determines that the gaming chip 70 should be collected, the chip management database 101 may update the movement history of the gaming chip 70 to move from the player to the game table according to the determination. By such an update and the subsequent update to indicate that the gaming chip 70 has been accepted by the chip tray, it can be confirmed whether the gaming chip 70 to be collected has been properly collected by the chip tray. In other words, when a movement history indicating that the gaming chip 70 should be collected is recorded with the entry / exit information 602 set to "OUT" and the location information 606 set to any player, but no movement history of acceptance by the chip tray is subsequently recorded, it becomes clear that the gaming chip 70 to be collected has not been properly collected.

[0095] In addition, in this embodiment, the chip IDs read from the chip tray before and after collection are compared to ascertain the chip IDs newly brought into the chip tray through collection, but instead of this, a special collected chip area may be provided in the chip tray to temporarily accommodate the collected chip tray, and an antenna independent of other chip tray portions may be provided in the collected chip area to ascertain the chip IDs of the collected gaming chips 70.

[0096] Alternatively, the chip ID of the gaming chip 70 to be collected may be identified by having the RFID tag 71 read by the collecting dealer antenna 5131 in the collection area while the gaming chip 70 is being moved from the betting area to the chip tray.

[0097] When a player wins a game, the player receives a payout of gaming chips 70. The dealer first places the gaming chips 70 to be paid out to the player from the chip tray in the payout area of ​​the game table. At this time, the payout dealer antenna 5132 reads the chip ID from the RFID tag 71 of the gaming chip 70 in the payout area. Since the table computer 151 knows which player is playing in each betting area, it can link the gaming chips 70 to be paid out with the player receiving the payout (the location information of the gaming chips 70 to be paid out is associated with the player).

[0098] It should be noted that the method of identifying the chip ID of the gaming chip 70 to be paid out and linking it to a player is not limited to the above. For example, the table computer 151 may identify the chip ID of the gaming chip 70 to be paid out by reading the chip ID of the gaming chip 70 contained in the chip tray before and after the payout, and link it to the player receiving the payout.

[0099] Also, when the gaming chip 70 to be paid out is placed in the betting area, the chip ID of the gaming chip 70 may be read by the betting area antenna 515 of the betting area. In this case, the chip ID of the gaming chip 70 that was bet (linked to the player) is read together with the chip ID of the paid out gaming chip 70 (linked to the dealer or casino), and the chip management computer 100 links the chip ID of the paid out gaming chip 70 to the player that was linked to the chip ID of the bet gaming chip 70.

[0100] Also, an antenna and a reading area for reading the RFID tag 71 of the gaming chip 70 to be paid out may be provided for each player position. Such an antenna and reading area may be installed between the betting area of ​​each player position and the dealer. In this case, since it is known which player is at each player position, the gaming chip 70 to be paid out can be linked to the player ID. In this case, the dealer may first place the gaming chip 70 to be paid out in the reading area of ​​the corresponding player position and have it read by the antenna there, and then move the gaming chip 70 to be paid out to the side of the betting chip in the betting area, or the corresponding player may take the gaming chip 70 to be paid out that the dealer placed in the reading area.

[0101] The table computer 151 reports the combination of the chip ID of the gaming chip 70 to be paid out and the player ID of the player receiving the payout to the chip management computer 100. In response to this report, the chip management computer 100 updates the transfer history in the chip management database 101 to indicate that the gaming chips 70 at the game table have been transferred to the player.

[0102] When dispensing, the RFID tag 71 of the gaming chip 70 taken out from the chip tray may be read once by the dispensing dealer antenna 5132, thereby identifying the chip ID of the gaming chip 70 to be dispensed.

[0103] In the above examples of Figs. 6 to 10, in each movement history of each gaming chip 70, not only location information but also the staff ID of the staff involved in the movement at that location may be recorded. In addition, when the location information is a player ID or a casino, the location information may be called owner information. In addition, in each movement history, status such as "valid", "invalid", "missing", "suspicious", "unredeemable", and "unplayable" may be recorded as status information of the gaming chip 70. In addition, whether the chip is valid or invalid may be indicated by a flag. Furthermore, in the above examples of Figs. 6 to 10, the record of each movement history may have the chip ID of each gaming chip 70 as well as information on its face value.

[0104] As described above, by reading the chip ID at each location, it is possible to record the movement history of each gaming chip 70 in the chip management database 101. This allows the chip management computer 100 to realize various functions described below.

[0105] (Time limit and destination error detection) In this function, the chip management computer 100 monitors the movement of the gaming chips 70 between the F / C bank room 13 and the game tables, and issues an alert if there is a problem. That is, the chip management computer 100 starts timing when it receives a report from the F / C bank computer 131 that a certain gaming chip 70 has left the F / C bank room 13 with a destination gaming table as the destination. Then, the chip management computer 100 may issue an alert if it does not receive a report from the table computer 151 of the destination gaming table within a predetermined time (e.g., 5 minutes) that the gaming chips 70 have been received. This alert may be sent to the dealer of the game table, the pit manager who manages the game table, or the like. At this time, the chip management computer 100 may update the status of the gaming chips 70 in the chip management database 101 to "missing," "unredeemable," "unplayable," or the like.

[0106] Furthermore, when the chip management computer 100 receives a report from the F / C bank computer 131 that a gaming chip 70 has been designated as a destination and left the F / C bank room 13, the chip management computer 100 may also issue an alert if it receives a report from the table computer 151 of a game table other than the game table designated as the destination that the gaming chip 70 has been received. In this case, the chip management computer 100 may update the status of the gaming chip 70 in the chip management database 101 to "wrong destination", "cannot be exchanged for cash", "cannot be played", etc.

[0107] (Detection of inappropriate movements) In this function, the chip management computer 100 refers to the chip management database 101 and issues an alert if there is an inappropriate movement of the gaming chips 70. Movements of the gaming chips 70 are limited to the patterns shown in Fig. 5, and any other movement patterns are inappropriate. Therefore, every time the chip management computer 100 updates the chip management database 101, it determines whether the movement related to the update is appropriate or not.

[0108] For example, when the cage 10 has the configuration shown in Fig. 1, the gaming chips 70 are not moved directly from the vault 11 to the cashier room 14, and, for example, the gaming chips 70 that have not been moved from the cashier room 14 to a player are not collected at a game table. If such a movement history is discovered, the chip management computer 100 judges it to be an inappropriate movement. Also, if gaming chips 70 that should be in the possession of a certain player are converted into cash at the cashier by another player, the possibility of money laundering is suspected. In this way, the chip management computer 100 detects an inappropriate movement and issues an alert.

[0109] (Real-time player chip totals) In this function, the chip management computer 100 refers to the chip management database 101, extracts only the gaming chips 70 held by any of the players in the latest information of the movement history, and calculates the total amount of these, thereby calculating the total amount of gaming chips 70 held by all players at that time, i.e., the casino's outstanding debt at that time.

[0110] In addition, the total amount of player chips may be calculated as the total amount of all gaming chips managed in the chip management database 101 minus the total amount of all gaming chips 70 in the cage 10 and the total amount of all gaming chips 70 on the game table.

[0111] (Central management of fills / credits) In this function, the chip management computer 100 extracts the gaming chips 70 at each game table and detects the number of each denomination by referring to the chip management database 101. If there are gaming chips 70 of a denomination for which the number is insufficient, a notification may be issued to the F / C bank computer 131 in the F / C bank room 13 and the table computer 151 of the game table in question to replenish (fill) gaming chips 70 of that denomination. This notification specifies the number of gaming chips 70 of each denomination to be replenished, or the total amount of gaming chips 70 of each denomination to be replenished.

[0112] Furthermore, the chip management computer 100 extracts the gaming chips 70 on each game table by referring to the chip management database 101, and detects the total number of gaming chips 70 on each game table. If the total number is equal to or greater than a predetermined number close to the upper limit that can be accommodated on the game table, a notification may be issued to the F / C bank computer 131 of the F / C bank room 13 and the table computer 151 of the game table to collect (credit) the gaming chips 70 from the table. This notification specifies the number of gaming chips 70 per denomination to be replenished, or the total amount of gaming chips 70 per denomination to be replenished.

[0113] Similarly, a notification may be issued regarding the movement of the gaming chips 70 within the cage 10. For example, when the number of gaming chips 70 is low in a window in the cashier room 14, a notification may be issued to the cashier computer 141 and the main bank computer 121 to urge them to replenish the gaming chips 70 in the cashier room 14.

[0114] In the above, a notification encouraging the user to move is issued to both the destination and the source, but instead, a notification may be issued to only one of the destination and the source. In a location that receives a notification encouraging the user to move, a staff member may instruct a computer of the location via an input device whether or not to accept the proposal to move, and if one of the destination and source locations accepts the proposal, the computer of the location may notify the other location of a command to move.

[0115] (Movement management of multiple gaming chips) In the above, a method of managing movement by updating the movement history in the chip management database 101 for each gaming chip 70 has been described, but when multiple gaming chips 70 move between locations, it is also possible to manage whether those multiple gaming chips 70 have moved without any excess or deficiency.

[0116] An example of moving a plurality of gaming chips 70 from the F / C bank room 13 to a game table (fill) will be described below. When gaming chips 70 are moved from the F / C bank room 13 to a predetermined game table, the F / C bank staff 33 reads the chip IDs of the gaming chips 70 to be moved using the F / C bank chip reader 133 of the F / C bank room 13. The F / C bank computer 131 reports the read chip IDs to the chip management computer 100. The chip management computer 100 stores the chip IDs (origin chip IDs) of the plurality of gaming chips 70 related to the fill, and refers to the chip management database 101 based on the report to obtain the face value of the chip IDs to grasp the total amount of the gaming chips 70 related to the fill (origin total amount). As a result, the chip management computer 100 grasps the origin chip ID, the total number of gaming chips 70 related to the fill (origin total amount), and the origin total amount based on the information from the F / C bank computer 131.

[0117] When the gaming chips 70 are carried to the game table, the dealer reads the chip IDs of the gaming chips 70 carried by the table chip reader of the game table, and the table computer 151 reports the multiple chip IDs that have been read to the chip management computer 100. The chip management computer 100 stores the multiple chip IDs (destination chip IDs), and based on the report, refers to the chip management database 101 to obtain the face value of the chip IDs and grasps the total amount of the gaming chips 70 related to the fill (destination total amount). As a result, the chip management computer 100 grasps the destination chip ID, the total number of gaming chips 70 related to the fill (destination total amount), and the destination total amount based on the information from the table computer 151.

[0118] The tip management computer 100 compares the source chip ID with the destination chip ID to determine whether they match exactly. The tip management computer 100 also compares the source total amount with the destination total amount to determine whether they match. The tip management computer 100 also compares the source total number of coins with the destination total number of coins to determine whether they match. If there is a mismatch in any of the above comparisons, the tip management computer 100 determines that the transfer was not performed correctly and issues an alert.

[0119] The case where a plurality of gaming chips 70 are transferred from a game table to the F / C bank room 13 (credit) is as follows. When gaming chips 70 are transferred from a game table to the F / C bank room 13, the dealer uses the payout table chip reader 1532 of the game table to read the chip ID of the gaming chip 70 to be transferred. The table computer 151 reports the read chip ID to the chip management computer 100. The chip management computer 100 stores the chip IDs (origin chip IDs) of the plurality of gaming chips 70 related to credit, and refers to the chip management database 101 based on the report to obtain the face value of the chip IDs and grasps the total amount of the gaming chips 70 related to credit (origin total amount). As a result, the chip management computer 100 grasps the origin chip ID, the total number of gaming chips 70 related to credit (origin total number), and the origin total amount based on the information from the table computer 151.

[0120] When the gaming chips 70 are carried to the F / C bank room 13, the F / C bank staff 33 reads the chip IDs of the gaming chips 70 carried by the F / C bank chip reader 133, and the F / C bank computer 131 reports the multiple chip IDs read to the chip management computer 100. The chip management computer 100 stores the multiple chip IDs (destination chip IDs) and, based on the report, refers to the chip management database 101 to obtain the face value of the chip IDs and grasps the total amount of the gaming chips 70 related to credit (destination total amount). As a result, the chip management computer 100 grasps the destination chip ID, the total number of gaming chips 70 related to credit (destination total number), and the destination total amount based on the information from the F / C bank computer 131.

[0121] The tip management computer 100 compares the source chip ID with the destination chip ID to determine whether they match exactly. The tip management computer 100 also compares the source total amount with the destination total amount to determine whether they match. The tip management computer 100 also compares the source total number of coins with the destination total number of coins to determine whether they match. If there is a mismatch in any of the above comparisons, the tip management computer 100 determines that the transfer was not performed correctly and issues an alert.

[0122] In the above, the chip ID, the total amount, and the total number of chips are compared, but it is also possible to determine whether the transfer was performed correctly by comparing only one of them. The total amount and the total number of chips may be calculated and compared for each face value of the gaming chips 70. For example, the source total amount and destination total amount may be calculated as "$600 for $10 chips, $400 for $100 chips."

[0123] In addition, when a notification encouraging a transfer is sent from the chip management computer 100 to the transfer destination or transfer source, it is possible to determine whether the transfer was carried out accurately by comparing the notification with the total amount from the transfer source, the notification with the total amount from the transfer destination, the notification with the total number from the transfer source, or the notification with the total number from the transfer destination.

[0124] (Management of fills by increasing the amount at the gaming table) When gaming chips 70 are carried from the F / C bank room 13 to the game table and the gaming chips 70 are replenished (filled) to the game table, the chip IDs of the gaming chips 70 carried to the game table are read by the F / C bank chip reader 133, and these chip IDs are reported from the F / C bank computer 131 to the chip management computer 100. The chip management computer 100 refers to the chip management database 101 to calculate the total amount of the reported gaming chips 70 (total fill amount).

[0125] The chip management computer 100 extracts the gaming chips 70 on the game table before the fill and calculates the total amount (existing total amount) by referring to the chip management database 101. Then, the chip management computer 100 adds the fill total amount to the calculated existing total amount to calculate the theoretical total amount of gaming chips 70 on the game table after the fill (theoretical post-fill total amount).

[0126] When gaming chips 70 are carried from the F / C bank room 13 to the game table, the collection table chip reader 1531 of the game table reads the chip ID of the carried gaming chip 70, and the table computer 151 reports it to the chip management computer 100. The chip management computer 100 refers to the chip management database 101 for the reported chip ID to obtain the face value, and calculates the actual total amount of the gaming chips 70 in the chip tray (actual post-fill total amount).

[0127] In addition, if the game table is provided with a cabinet or has a double chip tray, i.e., if the game table has a place to store chips other than the chip tray, the table computer 151 calculates the total amount of gaming chips 70 on the entire game table, including the chip tray and such storage places (however, does not include the player's gaming chips placed in the betting area), as the actual post-fill total amount.

[0128] The chip management computer 100 compares the theoretical post-fill total amount with the actual post-fill total amount, and issues an alert if the two do not match. With this configuration, it is possible to check whether the gaming chips 70 are correctly increased at the game table by filling.

[0129] Furthermore, the F / C bank room 13 keeps track of the chip IDs of all gaming chips 70 leaving the F / C bank room 13, and the game table also detects the chip IDs of all gaming chips 70 moved from the F / C bank room 13, so that when the theoretical post-fill total amount does not match the actual post-fill total amount, it is possible to keep track of the chip ID of the gaming chip 70 that caused the discrepancy. The chip management computer 100 changes the status of the gaming chip 70 that caused the discrepancy to a status such as "invalid," "cannot be exchanged for cash," or "cannot be played."

[0130] In the above, the theoretical total amount after fill was compared with the actual total amount after fill, but in addition to or instead of the amount (total amount) of the gaming chips 70, the number (total number) may be used to determine whether the fill was completed without any surplus or deficiency by comparing the theoretical total number of gaming chips 70 after fill at a game table (theoretical total number after fill) with the actual total number of gaming chips 70 after fill at the game table (actual total number after fill).

[0131] (Management of credits by deduction at gaming tables) When excess gaming chips 70 at a game table are carried from the game table to the F / C bank room 13 (credits), the payout table chip reader 1532 reads the chip IDs of the gaming chips 70 carried toward the F / C bank room 13, and these chip IDs are reported from the table computer 151 to the chip management computer 100. The chip management computer 100 refers to the chip management database 101 to calculate the total amount of the reported gaming chips 70 (total credits).

[0132] The chip management computer 100 extracts the gaming chips 70 at the game table before the credit and calculates the total amount (existing total amount) by referring to the chip management database 101. Then, the chip management computer 100 calculates the theoretical total amount of the gaming chips 70 at the game table after the credit (theoretical post-credit total amount) by subtracting the credit total amount from the calculated existing total amount.

[0133] At the game table, when the gaming chips 70 are carried toward the F / C bank room 13, the chip tray chip reader 154 of the game table reads the chip IDs of the gaming chips 70 stored at the game table, and the table computer 151 reports this to the chip management computer 100. The chip management computer 100 refers to the chip management database 101 for the reported chip ID to obtain the face value, and calculates the actual total amount of the gaming chips 70 in the chip tray (actual total amount after credit).

[0134] In addition, if the game table is provided with a cabinet or has a double chip tray, i.e., if the game table has a place for storing chips other than the chip tray, the table computer 151 calculates the total amount of gaming chips 70 on the entire game table, including the chip tray and such storage places (however, does not include the player's gaming chips placed in the betting area), as the total amount after actual credits.

[0135] The chip management computer 100 compares the theoretical post-credit total amount with the actual post-credit total amount, and issues an alert if the two do not match. With this configuration, it is possible to check whether the gaming chips 70 are correctly reduced by credits at the game table.

[0136] Furthermore, at the game table, the chip IDs of all gaming chips 70 carried from the game table to the F / C bank room 13 are known, and the F / C bank room 13 also detects the chip IDs of all gaming chips 70 moved from the game table, so that when the theoretical post-credit total amount does not match the actual post-credit total amount, it is possible to know the chip ID of the gaming chip 70 that caused the discrepancy. The chip management computer 100 changes the status of the gaming chip 70 that caused the discrepancy to a status such as "invalid," "cannot be exchanged for cash," or "cannot be played."

[0137] In the above, the theoretical total amount after credits was compared with the actual total amount after credits, but in addition to or instead of the amount (total amount) of the gaming chips 70, the number (total number) may be used to determine whether the credits have been completed without any surplus or deficiency by comparing the theoretical total number of gaming chips 70 after credits at a game table (theoretical total number after credits) with the actual total number of gaming chips 70 after credits at the game table (actual total number after credits).

[0138] In the above, the gaming chips 70 carried to the F / C bank room 13 are read by the payout table chip reader 1532 to grasp the total credit amount, and the theoretical post-credit total amount is calculated by subtracting the total credit amount from the existing total amount (the total amount of gaming chips 70 on the game table before credit is executed), but instead of this, the following may be performed. That is, when the chip management computer 100 issues a notice to the game table to prompt credit, and the game table executes credit in response to this notice, the total amount or the total number of gaming chips 70 related to credit specified in this notice (either may be specified for each face value) may be set as the total credit amount, and this total credit amount may be subtracted from the existing total amount to calculate the theoretical post-credit total amount. When the chip management computer 100 calculates the theoretical credit total amount, it compares this theoretical post-credit total amount with the actual post-credit total amount (the total amount of actual gaming chips 70 after credit on the game table) in the same manner as above to check whether the specified amount or number of gaming chips 70 have been taken out of the game table for credit.

[0139] (Verification according to staff work shifts) The cage 10 has a locked door to prevent arbitrary intrusion by people, and staff can enter and exit the cage by satisfying security conditions. Similar entry and exit security is also implemented between each room in the cage 10. Staff working in the cage 10 are required to authenticate when entering and leaving the cage 10 or their assigned room. When authenticating a staff member to exit, the chip management computer 100 verifies whether there has been any inappropriate movement of the gaming chips 70 since the staff member entered the room. The chip management computer 100 works in conjunction with the locking system, and does not permit exit if there has been any inappropriate movement of the gaming chips 70.

[0140] Similarly, at a game table, when a dealer leaves the game table, the dealer designates the end of his / her shift and has his / her ID card read by the table card reader 152. At this time, the chip management computer 100 verifies whether there has been any inappropriate movement of the gaming chips 70 since the dealer arrived at the game table, and issues an alert if there has been any inappropriate movement. When a dealer is replaced, the chip management computer 100 verifies whether the gaming chips 70 that should be at the game table are indeed there after the dealer leaves the table and before the next dealer arrives at the table, that is, whether the dealer leaving the table has not taken the gaming chips 70 out of the game table, and issues an alert if there is a problem.

[0141] In addition, in the game table, the gaming chips 70 may be stored in a place other than the chip tray. For example, the chip tray may be doubled, and the refill gaming chips 70 may be stored in the lower chip tray, or the refill gaming chips 70 may be stored in a cabinet provided in the game table. In these cases, it is desirable that the game table also includes an antenna for reading the RFID tags 71 of the gaming chips 70 stored in this way, and that the table computer 151 can always read the RFID tags 71 of all the gaming chips 70 on the game table.

[0142] (Monitoring inappropriate player purchases / cash redemptions) In this function, the chip management computer 100 verifies the history of purchase and redemption of gaming chips for each player, and issues an alert if there is any suspicious behavior. For example, if there is a purchase of gaming chips 70 of a predetermined amount or more and a redemption of gaming chips 70 of a predetermined amount or more within a predetermined time, an alert is issued for such behavior as suspicious behavior. Also, if gaming chips 70 are purchased and then are about to be redeemed without being used at a game table, and the amount of the redemption is a predetermined amount or more, an alert is issued for such behavior as suspicious behavior. Alternatively, for a player who has purchased gaming chips 70 of a predetermined amount or more within a predetermined time, an alert is issued for such behavior as suspicious behavior.

[0143] (Enable / disable in cage) The gaming chip 70 may be activated in the cage 10. This ensures security even if the gaming chip 70 is stolen between the time it is manufactured and the time it is brought into the cage 10, as such gaming chip 70 is not activated and cannot be used. For this reason, the chip management database 101 has a table that stores the chip IDs of valid gaming chips 70, and the chip management computer 100 refers to the table and verifies whether the chip ID is valid each time the chip ID of the gaming chip 70 is read by a cashier or a chip reader at a game table.

[0144] Also, when the gaming chips 70 are to be discarded, they are nullified within the cage 10 before being taken out of the cage 10. As a result, even if the gaming chips 70 taken out of the cage 10 for disposal are stolen, such gaming chips 70 cannot be used by the cashier or at the game table, ensuring security.

[0145] (Unregistered Player) Even an unregistered player can purchase gaming chips 70 and use the gaming chips 70 to play games at a game table. A common anonymous player ID is used for unregistered players. This allows the gaming chips 70 to be traced without interruption even if they are moved to an unregistered player while moving from one location to another from when the gaming chips 70 leave the cage 10 until when they return to the cage 10.

[0146] (others) A display device may be provided in the cashier's window to display the total amount of the gaming chips 70 and the confirmation result of validity. The cashier staff places the gaming chips 70 to be given to the player or received from the player in the cashier chip reader 143. The cashier chip reader 143 reads the face value and status stored in the RFID tag 71 of the gaming chip 70 (usually multiple). The cashier computer 141 displays the total value obtained by adding up the face values ​​read by the cashier chip reader 143 on the display device. In addition to the total amount, the number of gaming chips 70 of each face value may also be displayed.

[0147] Furthermore, if the read RFID tags 71 include gaming chips 70 with invalid status, the cashier computer 141 displays an error on the display device, and if the statuses of all gaming chips 70 are valid, the cashier computer 141 displays a pass on the display device or displays nothing. In addition to the status, the cashier computer 141 may also display whether there has been any inappropriate movement history up to that point. This allows the cashier staff and the player to agree that the gaming chips to be given to the player or received from the player are valid, and to hand over the gaming chips 70 only after the cashier staff and the player have agreed on the total amount.

[0148] In the above embodiment, when the chip reader at each location reads the RFID tag 71 of the gaming chip 70, the chip management computer 100 may verify whether the read chip ID is the chip ID of a valid chip, thereby confirming the validity of the chip ID, and may issue an alert if there is a problem. For this purpose, a table of valid chip IDs is recorded in the chip management database 101, and the chip management computer 100 refers to this table to verify whether the chip ID read at each location is valid. The chip ID may be encrypted.

[0149] In the above embodiment, the chip management computer 100 may, in addition to or instead of issuing an alert, flag the relevant player, gaming chip 70, or movement history record as an anomaly and record the time of the anomaly.

[0150] The configuration of the rooms in the cage 10 is not limited to that described above, and the number and arrangement of the rooms may be arbitrary. The game tables may be tables for playing baccarat, blackjack, or other card games, and may include locations for playing other games such as roulette in addition to the game tables.

[0151] Each of the above computers includes a processor and a memory, and the processor executes a computer program stored in the memory to perform the above operations. The program may be provided to the computer by a non-transitory storage medium, or may be provided to the computer in the form of a download. Furthermore, communication between the computers may be wired or wireless. Furthermore, in the above embodiment, each card reader reads an ID card to identify staff members and players at each location, but instead of an ID card, staff members and players may be identified by biometric authentication such as a fingerprint, a face image, an iris, or a voiceprint.

[0152] In the above embodiment, the movement of gaming chips 70 between locations is managed using each room in the cage 10 and the game table as examples of locations, but examples of locations are not limited to these. For example, a chip tray at a game table where a dealer stores collected chips and from which payout chips are dispensed, a cabinet at a table for storing gaming chips, and when the chip tray is configured in two tiers, each of the upper and lower chip trays can each be a location in the above embodiment, and the movement of gaming chips 70 between each location can be managed in a similar manner to that described above.

[0153] For example, the chip ID, total amount, and / or total number of gaming chips 70 taken out of a cabinet of a certain game table may be grasped, and an alert may be issued if the chip ID, total amount, and / or total number are not moved to a chip tray of the same game table within a predetermined time. Also, for example, in a certain double chip tray, it may be confirmed that gaming chips 70 taken out of a lower chip tray have been moved to an upper chip tray, or that gaming chips 70 taken out of an upper chip tray have been moved to a lower chip tray.

[0154] Furthermore, when a fill is performed, the gaming chips 70 brought from the F / C bank room 13 to the game table are read using the dealer antenna 513, the betting area antenna 515, or the chip tray antenna 514. The chip tray is provided with a button to recognize the start and end of the fill operation, and the gaming chips 70 on the chip tray before the fill and the gaming chips 70 on the chip tray after the fill are compared, and the gaming chips 70 increased by the fill are recognized as the filled gaming chips 70.

[0155] When crediting, the gaming chips 70 carried to the F / C bank room 13 are read by the collecting dealer antenna 5131, the paying dealer antenna 5132, the betting area antenna 515, or the chip tray antenna 514. The chip tray is provided with buttons to recognize the start and end of a credit operation, and the gaming chips 70 on the chip tray before crediting are compared with the gaming chips 70 after crediting, and the gaming chips 70 that have been reduced by crediting are recognized as gaming chips 70 to be credited.

[0156] The chip management computer 100 may be capable of outputting the chip inventory (chip ID) of each location (cage, chip tray, etc.). The chip management computer 100 may be capable of specifying a past point in time and outputting the inventory at that point in time.

[0157] Also, an alert may be issued when a suspicious gaming chip (a flagged gaming chip) is about to be cashed in by the cashier.

[0158] The chip management database 101 may also be capable of storing the cash conversion history of each player. The chip management computer 100 may also be capable of outputting the chip ID that the player should possess.

[0159] Information such as chip set, casino information, location information, and redemption possibility may be written to the RFID tag 71. Alternatively, such information may be associated with the chip ID and stored in the chip management database 101. When the RFID tag 71 is read at a certain location, the chip management computer 100 or a computer at each location may check whether the gaming chip 70 is one that should be at that location based on such information.

[0160] Also, a set (chip set) of gaming chips 70 that can be used and the type of gaming chips may be set for each area. For example, when an RFID tag 71 is read at a certain game table, the table computer 151 or the chip management computer 100 checks whether the chip set is to be used at that game table.

[0161] A flag may be set in association with the chip ID for gaming chips 70 that have been used for a certain number of years. Gaming chips 70 that have been used for a certain number of years can be located and collected. If a player has gaming chips 70 that have been used for a certain number of years, a signal is output when the chip ID is detected by the cashier or game table.

[0162] When a player who has possibly stolen gaming chips 70 sits at a table, the table computer 151 or the chip management computer may issue a warning to a staff member (a supervisor). In order to prevent money laundering, the cashier computer 141 or the chip management computer 100 detects chips that are purchased but not played and then redeemed for cash.

[0163] When cashing or purchasing chips for an amount equal to or greater than a threshold is performed, the cashier associates the player's photograph with the chip ID. Also, a unique ID is assigned to anonymous players (players without a member card) to trace their chips. Also, for anonymous players, a photograph of the face may be taken when purchasing chips, and the face image may be associated with a player ID and registered in the chip management database 101, and the player ID may be identified by facial recognition at each location thereafter (table, cashier, etc.). The chip management computer 100 may invalidate the status of all chips associated with players on the blacklist.

[0164] When a player without a member card bets gaming chips 70 at a game table, the chip management computer 100 records the play in the chip management database 101 by linking it to a unique ID issued on the spot and / or a player ID linked to the gaming chips 70. At this time, the play may be linked to an ID obtained by a facial image or facial recognition. Also, if the member card is recognized later, the play record may be recorded by linking it to the member card ID retroactively.

[0165] [Second embodiment: Gaming chip management using a table chip reader] (Management system configuration) 11 is a diagram showing the configuration of a management system according to a second embodiment of the present invention. The management system 2000 is a system for managing gaming chips 70 in a game table 42 for playing a game using gaming chips 70 with built-in RFID tags 71. The game table 42 includes a chip tray 421 for storing dealer's gaming chips 70, betting areas 422a to 422e for placing gaming chips to be bet on a game, and a collection area 423a and a payout area 423b that are separate from the betting areas 422a to 422e and the chip tray 421. The collection area 423a and the payout area 423b are both located between the betting areas 422a to 422e and the chip tray 421.

[0166] A collecting dealer antenna 5131 is embedded in the collecting area 423a for reading the RFID tags 71 of gaming chips 70 collected after losing a game in the collecting area 423a. A paying out dealer antenna 5132 is embedded in the paying out area 423b for reading the RFID tags 71 of gaming chips 70 paid out to players who win a game in the paying out area 423b. The collecting dealer antenna 5131 reads the RFID tags 71 of gaming chips 70 collected from the betting areas 422a to 422e before being placed in the chip tray 421. The paying out dealer antenna 5132 reads the RFID tags 71 of gaming chips 70 taken out of the chip tray 421 before being paid out to the betting areas 422a to 422e.

[0167] The chip tray 421 is provided with a chip tray antenna 514 for reading the RFID tag 71 of the gaming chip 70 accommodated in the chip tray 421. The collecting dealer antenna 5131, the paying out dealer antenna 5132, and the chip tray antenna 514 are each connected to the first reading device 81.

[0168] The first reading device 81 controls the collecting dealer antenna 5131, the dispensing dealer antenna 5132, and the chip tray antenna 514, respectively, to transmit radio waves to the RFID tag 71 and to decode the signals received by each antenna to acquire information on the RFID tag 71. In this embodiment, the collecting dealer antenna 5131, the dispensing dealer antenna 5132, and the chip tray antenna 514 are connected to the same first reading device 81, so that the first reading device 81 controls the collecting dealer antenna 5131, the dispensing dealer antenna 5132, and the chip tray antenna 514 in a time-division manner, respectively, to perform reading.

[0169] The collecting dealer antenna 5131, the dispensing dealer antenna 5132, and the tip tray antenna 514 may be connected to separate reading devices. In this case, reading may be performed independently by the collecting dealer antenna 5131, the dispensing dealer antenna 5132, and the tip tray antenna 514, and each antenna can perform reading at any timing.

[0170] Betting area antennas 515a to 515e are embedded in the betting areas 422a to 422e, respectively. The betting area antennas 515a to 515e read the RFID tags 71 of the gaming chips 70 placed in the betting areas 422a to 422e, respectively. The betting area antennas 515a to 515e are connected to the second reading device 82, respectively.

[0171] Cameras 91 and 92 are installed on the game table 42. The cameras 91 and 92 each take images of the gaming chips 70 placed on the betting areas 422a to 422e from different angles to generate images. The cameras 91 and 92 each take images of the table surface of the game table 42 from diagonally above. The cameras 91 and 92 also each take images of players participating in the game. The cameras 91 and 92 are each connected to an image recognition device 83.

[0172] The image recognition device 83 recognizes the positions, types, and numbers of the gaming chips 70 placed in the betting areas 422a to 422e by performing image recognition processing on the images generated by the cameras 91 and 92. The image recognition device 83 further generates a skeletal model of a player participating in a game by performing image recognition processing on the images generated by the cameras 91 and 92. Note that the image recognition device 83 for recognizing the gaming chips 70 and the image recognition device 83 for generating a skeletal model of a player may be separate devices. Also, the camera for generating an image for recognizing the gaming chips 70 and the camera for generating an image for generating a skeletal model of a player may be separate cameras.

[0173] The game table 42 is provided with an electronic shoe 94 as a card distribution device and a game result determination device. The electronic shoe 94 has a mechanism for drawing playing cards one by one by the dealer's operation. The electronic shoe 94 reads the rank of the drawing playing card. For this purpose, a code mark indicating the rank is written on the playing card, and the electronic shoe 94 is provided with an optical sensor for reading this code mark. Alternatively, the electronic shoe 94 may be provided with a camera for taking a picture of the rank marking of the drawing playing card to generate an image, and an image recognition device for performing image recognition on the image to recognize the rank marking.

[0174] The electronic shoe 94 is equipped with a processor that determines the game result according to the rules of the baccarat game based on the ranks of the playing cards drawn. The electronic shoe 94 is also equipped with buttons for the dealer to operate. The baccarat game determines the game result, i.e., player win, banka win, tie, player pair, banka pair, lucky six, etc., based only on the ranks of the playing cards drawn in sequence from the electronic shoe 94. The electronic shoe 94 recognizes the button operation to recognize the start or end of the game, and recognizes the ranks of the playing cards drawn in one game and the order in which they were drawn.

[0175] The game table 42 is further provided with a cash insertion port 93 for inserting cash. The cash insertion port 93 is provided with a cash sensor 931 for detecting cash passing therethrough. When a player purchases gaming chips 70 at the game table 42, the dealer receives cash from the player and inserts it into the cash insertion port 93, and pays out gaming chips of the same amount from the chip tray 421 to the player.

[0176] The management system 2000 further includes a management device 84. The management device 84 is connected to the first reading device 81, the second reading device 82, the image recognition device 83, and the electronic shoe 94. The management device 84 acquires the reading results of the RFID tag 71 of the gaming chip 70 by the first reading device 81 and the second reading device 82, the image recognition results by the image recognition device 83, and the game results by the electronic shoe 94, and manages the movement of the gaming chip 70 on the game table 42 based on these.

[0177] (Detection of fraud or errors in collection and disbursement) The management device 84, as a collection determination means, determines whether or not the gaming chips 70 to be collected from the bet areas 422a to 422e have been collected from the bet areas 422a to 422e and read by the collection dealer antenna 5131. Specifically, the management device 84 determines whether or not the amount of the gaming chips 70 read by the collection dealer antenna 5131 matches the amount to be collected. The management device 84 determines the amount to be collected based on the bet object, the bet amount, and the game result.

[0178] For this purpose, the management system 2000 grasps the betting object and the betting amount. The betting object and the betting amount are recognized by using the cameras 91, 92 and the image recognition device 83. The image recognition device 83, as a bet determination means, determines the betting object and the betting amount of the gaming chips 70 bet on the betting areas 422a to 422e. The betting areas 422a to 422e of each player position are provided with the following betting objects: player (P), banker (B), tie (T), player pair (PP), and banker pair (BP).

[0179] FIG. 12 is a diagram for explaining image recognition in an image captured by a camera in the second embodiment of the present invention. The example in FIG. 12 is an image captured by a camera 91. An image 901 shows a betting area, gaming chips placed in the betting area, and a player. The image recognition device 83 performs image recognition processing for detecting gaming chips on the image 901, and detects gaming chips from the image 901. A neural network can be used for this image recognition processing. The detected stack of gaming chips is surrounded by rectangular frames c1 and c2.

[0180] The image recognition device 83 further detects the skeleton to generate skeleton models sm1 and sm2 of the player. The image recognition device 83 further detects the face of the player to extract face areas f1 and f2. Neural networks can be used for each of the skeleton detection and face detection.

[0181] The image recognition device 83 recognizes the position where the gaming chip stack is placed, that is, the bet object on which the gaming chip stack is betted, based on the positions in the image of the centers cp1, cp2 of the lower sides of the rectangular frames c1, c2 of the detected gaming chip stack. As shown in FIG. 12, the gaming chips that the player is holding and moving are also recognized, so the image recognition device 83 may receive a signal indicating that the first playing card of the game has been drawn from the electronic shoe 94 and detect the gaming chips from the image at that time. At the timing when the first playing card is drawn, the player cannot touch the gaming chips that have been bet, and the positions of the gaming chips are fixed. Note that, as the image recognition process, segmentation may be performed to identify the area of ​​the gaming chip stack. In this case, the image recognition device 83 recognizes the bet object on which the gaming chip stack is betted, based on the position in the image of the lowest point of the identified area of ​​the gaming chip stack.

[0182] The image recognition device 83 may further recognize the type of each gaming chip constituting the stack by image recognition. As shown in Fig. 12, a colored layer indicating the face value (type) is provided on the side of the gaming chip 70, and by further detecting this colored layer from the rectangular frames c1 and c2 of the detected stack, the type and number of gaming chips 70 included in the stack can be recognized.

[0183] In addition, the type and number of gaming chips in each of the betting areas 422a to 422e may be recognized by the betting area antennas 515a to 515e and the second reading device 82. That is, the positions of the gaming chips bet on the betting areas 422a to 422e (betting targets) may be recognized by the cameras 91, 92 and the image recognition device 83, and the type and number may be recognized by the betting area antennas 515a to 515e and the second reading device 82.

[0184] Furthermore, if a chip ID is written on the side of the gaming chip 70, the chip ID may be recognized by recognizing the images generated by the cameras 91 and 92 with the image recognition device 83.

[0185] FIG. 13A is a diagram showing another example of the gaming chip according to the second embodiment of the present invention, and FIG. 13B is a diagram showing yet another example of the gaming chip according to the second embodiment of the present invention. As shown in FIGS. 13A and 13B, in the gaming chips 70′ and 70″, A side ID, which is identification information, is written on the side. In the example of FIG. 13A, the side ID is expressed by the presence or absence of multiple dots (dot pattern). In this example, the side ID is expressed by the presence or absence of dots in a dot row consisting of eight dots, so that 2 to the power of 8 pieces of information can be expressed. In the example of FIG. 13B, the side ID is expressed by a number string. In this example, it is expressed by an eight-digit number, so that 10 to the power of 8 pieces of information can be expressed. The side ID may be expressed by a matrix pattern, a barcode, or a character string. The side ID is written within a range of 1 / 6 or less of the circumference of the side of the gaming chip. On the side of the gaming chip, multiple side IDs are written at predetermined intervals in the circumference direction.

[0186] The side ID may be a unique ID that uniquely identifies each gaming chip, or may be information indicating the group (e.g., value) to which each gaming chip belongs, i.e., information that may be duplicated with other gaming chips. In particular, when the side ID is expressed as a number string, the side ID may be a unique ID, and when the side ID is expressed as a dot pattern (dot string), the side ID may be information on the group to which the gaming chip belongs.

[0187] The side surface of the gaming chip 70', 70'' is divided into three layers in the thickness direction. In the form of the side ID, the first and third layers are different colors depending on the value of the gaming chip, and the second layer (center line) in the middle is a color (e.g., black) that is common to all gaming chips regardless of the value of the gaming chip. The side ID can be printed or laser engraved.

[0188] The gaming chip 70', 70' has a built-in RFID tag. At least a unique ID that uniquely identifies the gaming chip and information on the group to which the gaming chip belongs (for example, value) are recorded in the database. Note that in this embodiment, the unique ID stored in the RFID tag and the unique ID expressed as the side ID are the same ID, but these may be different IDs and the two IDs given to the same gaming chip may be associated in the database.

[0189] The Gaming Chip 70´,70´´ has a built-in capsule and an RFID tag , and is housed in a capsule. A decal indicating information on the value of the gaming chip, information on the casino where the gaming chip is used, and the like is attached to the outside of the capsule. A unique ID that uniquely identifies the gaming chip is printed on the capsule. The unique ID printed on the capsule may be the same as or different from the unique ID stored in the RFID tag. When the unique ID printed on the capsule and the unique ID stored in the RFID tag are different, the unique IDs may be associated with each other and stored in a database. The unique ID may be printed on the surface of the chip under the decal. The unique ID may be printed on the surface of the chip with invisible ink such as UV ink or infrared absorbing ink.

[0190] Fig. 14 is a diagram showing an example of an image captured by a camera according to the second embodiment of the present invention. In the example of Fig. 14, multiple stacks of gaming chips placed in multiple betting areas are captured. The sides of the chips can also be observed in the images captured by cameras 91 and 92.

[0191] The image recognition device 83 receives the captured images generated by the cameras 91 and 92 and performs image recognition on the images to recognize at least the position, type, and side ID information of each of the multiple gaming chips. The image recognition device 83 performs image recognition at least in part by using an image recognition engine of a neural network.

[0192] Since stacks of gaming chips are present at arbitrary locations in the images captured by the cameras 91 and 92, the image recognition device 83 first uses a neural network to extract the stack of gaming chips (or one gaming chip) from the captured image. The image recognition device 83 then uses another neural network to extract the colored layers (center lines) of each of the gaming chips from the extracted portion of the stack.

[0193] The image recognition device 83 further determines the value of each gaming chip based on the colors above and below the extracted center line. The image recognition device 83 further reads the side ID from the center line, and in the case of Fig. 13A, obtains the side ID information by decoding the dot pattern, and in the case of Fig. 13B, obtains the side ID information by deciphering the numbers.

[0194] FIG. 15 is a table showing an example of data stored in a database according to the second embodiment of the present invention. As shown in FIG. 15, the database 85 stores, for each chip ID represented by a side ID, information on the face value (type), owner, and status. The face value is, for example, $10, $50, $100, $500, etc. When the gaming chip 70 is owned by a player, the player ID is stored as information on the owner, and when the gaming chip 70 is owned by a casino, information that the owner is the casino is stored. Information on the status stored is valid, invalid, suspect, etc.

[0195] The management device 84 can know the face value, owner, and status of each gaming chip 70 by referring to the database 85 based on the side ID (ie, chip ID) recognized by the image recognition device 83.

[0196] The management device 84 calculates the total amount of gaming chips bet on each bet object, i.e., the bet amount, based on the value and number of gaming chips recognized as described above. In the above embodiment, the management device 84 uses the cameras 91, 92 and the image recognition device 83 to determine the amount of gaming chips bet on each bet object, or uses the cameras 91, 92 and the image recognition device 83 to recognize the position of the gaming chips 70, and uses the bet area antennas 515a-515e and the second reading device 82 to recognize the bet amount of each bet area 422a-422e, but instead, the management device 84 can also recognize the position, type, and number of the gaming chips 70 using the bet area antennas 515a-515e and the second reading device 82.

[0197] That is, in the betting areas 422a to 422e, if separate antennas are provided for each betting object and the RFID tags 71 of the gaming chips 70 can be read for each betting object, the positions, types, and numbers of gaming chips can be recognized without using the cameras 91, 92 and the image recognition device 83. In this case as well, the management device 84 recognizes the betting objects and betting amounts in each of the betting areas 422a to 422e based on the information on the positions, types, and numbers obtained from the second reading device 82.

[0198] Based on the information on the bet objects and bet amounts recognized as described above, and on the game result information obtained from the electronic shoe 94, the management device 84 determines whether the stacks of gaming chips 70 bet in each bet area 422a to 422e have won or lost the game, determines that the stacks of gaming chips 70 that have been lost are stacks that should be collected, and determines the amount of gaming chips 70 to be paid out for the stacks of gaming chips 70 that have been won, based on the redemption rate defined for the relevant bet object.

[0199] When the game result is determined, the dealer first collects the lost gaming chips (i.e., the lost bets) from each player. At this time, the dealer places a stack of gaming chips 70 collected from a certain player (losing bet stack) in the collection area 423a and has it read by the collection dealer antenna 5131. Then, the dealer stores the stack of gaming chips 70 in the chip tray 421. Then, the dealer collects another stack of gaming chips 70 (losing bet stack), places it in the collection area 423a, has it read by the collection dealer antenna 5131, and stores it in the chip tray 421. This is performed for all stacks of gaming chips 70 (losing bet stacks). At this time, the dealer collects the lost gaming chips 70 in the order of the player positions (for example, in ascending order of player position numbers).

[0200] At this time, the management device 84 functions as a recovery determination means, and determines whether the amount and chip ID of the gaming chips 70 read by the recovery dealer antenna 5131 in the recovery area 423a for each bet lost in the game match the amount and chip ID of the lost bet stack bet in any of the bet areas 422a to 422e. The management device 84 sets the amount of the gaming chips 70 to be recovered, determined according to the bet object, bet amount, and game result as described above, as the amount of the lost bet stack. Alternatively, the management device 84 may set the amount of the gaming chips 70 that can no longer be read from the bet areas 422a to 422e as the amount and chip ID of the lost bet stack and determine whether the amount and chip ID match the amount and chip ID read in the recovery area 423a.

[0201] When all the lost bet stacks have been collected, the management device 84 judges whether the increased amount of the gaming chips 70 in the chip tray 421 read using the chip tray antenna 514 matches the total amount and chip ID of the lost bet stacks, i.e., the total amount and chip ID of the amount to be collected. The management device 84 also judges whether the increased amount and added chip ID of the gaming chips 70 in the chip tray 421 read using the chip tray antenna 514 matches the total amount and chip ID of all the collected amounts of the gaming chips 70 read by the collection dealer antenna 5131 in the collection area 423a every time a lost bet stack is collected. For this purpose, the management device 84 acquires the total amount and chip ID of the gaming chips 70 in the chip tray 421 read by the chip tray antenna 514 before starting collection, and acquires the total amount and chip ID of the gaming chips 70 in the chip tray 421 read by the chip tray antenna 514 again after all the collection is completed, and calculates the increased amount and added chip ID by calculating the difference between them.

[0202] The dealer's collection operation does not have to be performed by reading each stack in the collection area 423a and storing them in the chip tray 421 as described above. For example, each stack may be moved to the collection area 423a in order, and after all the lost bet stacks are collected in the collection area 423a, they may be stored in the chip tray 421. In this case, the management device 84 may acquire the added information as information on the newly collected gaming chips 70 based on the information read by the collection dealer antenna 5131 each time the newly collected gaming chips 70 are added to the collection area 423a.

[0203] In addition, when there are multiple losing bet stacks, as described above, the order of collection is known, and therefore the total amount and chip ID of the gaming chip stack to be read by the collection area 423a every time a losing bet stack is collected is also known to the management device 84. The management device 84 compares this known total amount and chip ID of the gaming chips 70 to be collected (to be read by the collection dealer antenna 5131) with the total amount and chip ID of the gaming chips 70 actually read by the collection dealer antenna 5131, thereby determining whether collection has been performed correctly. If collection has not been performed correctly, the management device 84 outputs or records the player position or player information of the bet stack involved in such an illegal collection.

[0204] When the dealer finishes collecting, he or she pays out the winning gaming chips 70. At this time, the dealer places a stack of gaming chips 70 to be paid out from the chip tray 421 in the payout area 423b, has the payout dealer antenna 5132 read it, and then places the gaming chips 70 to be paid out next to the winning gaming chips, i.e., in the betting areas 422a to 422e. The player who wins the game receives the gaming chips 70 thus placed in the betting areas 422a to 422e together with the gaming chips 70 that he or she bet.

[0205] At this time, the management device 84 functions as a payout determination means, and determines whether or not the gaming chips 70 of the amount to be paid out for each winning bet in the game have been read by the payout dealer antenna 5132. The management device 84 determines whether the payout amount calculated from the bet amount of the winning gaming chips and the redemption rate defined for the bet object matches the amount of the gaming chips 70 read by the payout dealer antenna 5132 in the payout area 423b. In addition, when there are multiple winning bet stacks, the dealer pays out the gaming chips 70 in the order of the player positions (for example, in the order of the smallest player position number). Therefore, the total amount of the stack of gaming chips 70 to be paid out, that is, to be read by the payout dealer antenna 5132, is known to the management device 84. Therefore, each time the gaming chips 70 to be paid out are read by the payout dealer antenna 5132, the management device 84 compares this known total amount with the total amount of the gaming chips 70 actually read by the payout dealer antenna 5132, and if there is a discrepancy, it identifies and outputs or records the player position or player related to the discrepancy.

[0206] The management device 84 may further determine whether the amount of gaming chips added to the bet areas 422a to 422e matches the amount of gaming chips 70 read by the payout dealer antenna 5132 in the payout area 423b. This determination makes it possible to confirm whether the gaming chips 70 placed in the payout area 423b have been paid to the correct player position.

[0207] When the payout for all winning bet stacks is completed, the management device 84 judges whether the reduced amount of the gaming chips 70 in the chip tray 421 read using the chip tray antenna 514 matches the total amount to be paid out. In addition, the management device 84 judges whether the reduced amount of the gaming chips in the chip tray 421 read using the chip tray antenna 514 matches the total amount for all payouts of the gaming chips 70 read by the payout dealer antenna 5132 in the payout area 423b every time a payout is made to a winning bet stack. For this purpose, the management device 84 acquires the total amount of the gaming chips 70 in the chip tray 421 read by the chip tray antenna 514 after all collections are completed and before starting payout, and acquires the total amount of the gaming chips 70 in the chip tray 421 read by the chip tray antenna 514 again after all payouts are completed, and calculates the reduction amount by finding the difference between them.

[0208] In the above embodiment, when all collections are completed, it is determined whether the increment in the chip tray 421 is correct, and when all payouts are completed, it is determined whether the decrement in the chip tray is correct, but instead, after all collections and payouts are completed, it may be determined whether the increment or decrement of the gaming chips in the chip tray 421 due to all collections and payouts is correct. In this case, too, the management device 84 may determine whether the increment or decrement calculated from the bet object, bet amount, and game result matches the actual increment or decrement in the chip tray 421, or may obtain the increment or decrement by adding and subtracting the total amount of the gaming chips 70 read by the collection dealer antenna 5131 in the collection area 423a and the total amount of the gaming chips 70 read by the payout dealer antenna 5132 in the payout area 423b, and determine whether the increment or decrement obtained in this way matches the actual increment or decrement in the chip tray 421.

[0209] As described above, when collecting, the management device 84 specifies the gaming chips 70 to be collected based on the bet object, bet amount, and game result, and judges whether the amount and / or chip ID of the gaming chips 70 read by the collecting dealer antenna 5131 of the collection area 423a is the amount and chip ID to be collected. In addition, the management device 84 judges whether the amount and / or chip ID of the gaming chips 70 that are no longer read by the betting area antennas 515a to 515e of the betting area 422a matches the amount and / or chip ID of the gaming chips 70 read by the collecting dealer antenna 5131 of the collection area 423a when collecting. In addition, the management device 84 judges whether the amount and / or chip ID of the gaming chips 70 read by the collecting dealer antenna 5131 of the collection area 423a matches the amount and / or chip ID of the gaming chips 70 added to the chip tray 421 when collecting.

[0210] Regarding payout, the management device 84 specifies the amount of gaming chips 70 to be paid out based on the bet object, bet amount, and game result, and judges whether the amount of gaming chips 70 read by the payout dealer antenna 5132 of the payout area 423b is the amount to be paid out. Furthermore, the management device 84 judges whether the amount and / or chip ID of the gaming chips 70 paid out from the chip tray 421 and decreased in the chip tray 421 at the time of payout matches the amount and / or chip ID of the gaming chips 70 read by the payout dealer antenna 5132 at the time of payout. Furthermore, the management device 84 judges whether the amount and / or chip ID of the gaming chips 70 read by the payout dealer antenna 5132 of the payout area 423b at the time of payout matches the amount and / or chip ID of the gaming chips 70 added to the bet areas 422a to 422e and read by the bet area antennas 515a to 515e at the time of payout.

[0211] (Exchange Determination) The management device 84 determines whether the exchange, i.e., the equivalent exchange between the gaming chips presented by the player and the gaming chips presented by the dealer, has been performed correctly. For this purpose, the management device 84 recognizes that an exchange transaction is being performed when the exchange has been performed.

[0212] An exchange transaction is started when a player places his / her gaming chips 70 for which exchange is required in the collection area 423a and notifies the dealer of his / her intention to exchange. The dealer places gaming chips 70 equivalent to the gaming chips presented by the player and placed in the collection area 423a (but with a different face value (type)) in the payout area 423b. That is, in an exchange transaction, the gaming chips 70 presented by the player are present in the collection area 423a and the gaming chips 70 presented by the dealer are present in the payout area 423b at the same time.

[0213] When the collecting dealer antenna 5131 in the collecting area 423a and the paying dealer antenna 5132 in the paying area 423b detect gaming chips 70 simultaneously or simultaneously within a predetermined time interval, the management device 84 determines that an exchange transaction is taking place and activates the exchange mode. In the exchange mode, when the management device 84 determines that an exchange transaction is taking place, it compares the total amount of the gaming chips 70 read in the collecting area 423a with the total amount of the gaming chips 70 read in the paying area 423b and determines whether the two are equal, thereby determining whether the exchange is taking place correctly.

[0214] In addition, in the exchange mode, the management device 84 may determine whether the number of gaming chips 70 read in the collection area 423a is different from the number of gaming chips 70 read in the payout area 423b, and then start the exchange mode or determine whether the exchange has been performed correctly. In addition, the management device 84 may refer to the database 85 for the gaming chips 70 read in the collection area 423a to identify the owner, confirm that it is one of the player IDs, and refer to the database 85 for the gaming chips 70 read in the payout area 423b to identify the owner, confirm that it is the casino, and then start the exchange mode or determine whether the exchange has been performed correctly.

[0215] In the above embodiment, the area where the gaming chips 70 put by the player are placed during the exchange is the collection area 423a, and the area where the gaming chips 70 put by the dealer are placed is the payout area 423b, but the operation of the exchange is not limited to this. For example, the area where the gaming chips 70 put by the player are placed may be the payout area 423b, and the area where the gaming chips 70 put by the dealer are placed may be the collection area 423a. Alternatively, when the gaming chips 70 put by the player are placed in the collection area 423a, the gaming chips 70 put by the dealer may be placed in the payout area 423b, and when the gaming chips 70 put by the player are placed in the payout area 423b, the gaming chips 70 put by the dealer may be placed in the collection area 423a. In other words, the locations where the gaming chips 70 provided by the player and the gaming chips 70 provided by the dealer should be placed are not fixed, and one may be placed in either the collection area 423a or the payout area 423b, and the other may be placed in the other of the collection area 423a and the payout area 423b.

[0216] In this case, the management device 84 may also start the exchange mode when it detects that gaming chips 70 are present in both the collection area 423a and the payout area 423b at the same time. Alternatively, the management device 84 may further compare the total amount of gaming chips 70 placed in the collection area 423a with the total amount of gaming chips 70 placed in the payout area 423b and determine that they are equal, and / or compare the number of gaming chips 70 placed in the collection area 423a with the number of gaming chips 70 placed in the payout area 423b and determine that they are equal, and may start the exchange mode or determine that the exchange has been performed correctly.

[0217] In the exchange mode, the management device 84 compares the total amount of the gaming chips 70 placed in the collection area 423a with the total amount of the gaming chips 70 placed in the payout area 423b, and if the two do not match, controls the alert device 86 to output an alert. The management device 84 also determines whether the owner of the gaming chips 70 read in either the collection area 423a or the payout area 423b is any player ID, and the owner of the gaming chips 70 read in the other of the collection area 423a and the payout area 423b is a casino, and if this is not the case, for example, if the owner of both gaming chips 70 is a casino, or if the owner of both gaming chips 70 is any player ID, controls the alert device 86 to output an alert. In this case, the alert device 86 particularly warns that the exchange is not between the player and the casino.

[0218] The alert device 86 may be equipped with an audio output device and output the alert by audio, may be equipped with a lamp and output the alert by lighting the lamp, or may be equipped with a display device and output the alert on a display screen.

[0219] In the above embodiment, the management device 84 activates the exchange mode when it detects that gaming chips 70 are present in the collection area 423a and the payout area 423b at the same time, but the management device 84 may activate the exchange mode when it detects that gaming chips 70 that were in the chip tray 421 and gaming chips 70 that were not in the chip tray 421 are placed in the collection area 423a and the payout area 423b. Also, the management device may activate the exchange mode when it detects that gaming chips 70 owned by a player and gaming chips 70 owned by a non-player are placed in the collection area 423a and the payout area 423b.

[0220] (Fill and credit transactions) When the gaming chips 70 stocked in the chip tray 421 of the game table 42 become low, the gaming chips 70 are replenished to the chip tray 421 from outside the game table 42 (fill transaction). Also, when the gaming chips 70 stocked in the chip tray 421 of the game table 42 become excessive, the gaming chips 70 are moved from the chip tray 421 to outside the game table (credit transaction).

[0221] In a fill transaction, similarly to the first embodiment, the F / C bank chamber 13 grasps the chip IDs of all gaming chips 70 leaving the F / C bank chamber 13, and the game table 42 also detects the chip IDs of all gaming chips 70 moved from the F / C bank chamber 13. This allows the theoretical chip IDs and total amount of all gaming chips 70 to be filled to be compared with the chip IDs and total amount of all gaming chips 70 that have actually been filled.

[0222] The dealer reads the RFID tag 71 of the gaming chip 70 to be filled, which has been moved from the F / C bank room 13 to the game table 42, with the collection dealer antenna 5131 in the collection area 423a, and then stores the gaming chip in the chip tray 421. The chip tray antenna 514 of the chip tray 421 reads the RFID tag 71 of the gaming chip 70 stored in the chip tray 421 after filling.

[0223] The management device 84 acquires the chip IDs and total amount of all gaming chips 70 that have left the F / C bank room 13, and compares these with the chip IDs and total amount of the gaming chips 70 read by the collecting dealer antenna 5131. In addition, the management device 84 compares the chip IDs and total amount of the RFID tags 71 of the gaming chips 70 placed in the collecting area 423a and read by the collecting dealer antenna 5131 in a fill transaction with the chip IDs and total amount of the gaming chips 70 newly added to the chip tray 421 by storing those gaming chips 70 in the chip tray 421.

[0224] If the management device 84 determines that there is a mismatch in any of these comparisons, it controls the alert device 86 to output an alert, which in this case specifically warns that the fill transaction has not been performed correctly.

[0225] In a credit transaction, similarly to the first embodiment, the F / C bank chamber 13 grasps the chip IDs of all gaming chips 70 entering the F / C bank chamber 13, and the game table 42 also detects the chip IDs of all gaming chips 70 moving to the F / C bank chamber 13. This allows the theoretical chip IDs and total amount of all gaming chips 70 to be credited to be compared with the chip IDs and total amount of all gaming chips 70 actually credited.

[0226] The management device 84 acquires the chip IDs and total amount of all gaming chips 70 entering the F / C bank room 13, and compares these with the chip IDs and total amount of the gaming chips 70 read by the payout dealer antenna 5132. The management device 84 also compares the chip IDs and total amount of the RFID tags 71 of the gaming chips 70 placed in the payout area 423b and read by the payout dealer antenna 5132 in a credit transaction with the chip IDs and total amount of the gaming chips 70 reduced from the chip tray 421 by removing those gaming chips 70 from the chip tray 421.

[0227] If the management device 84 determines that there is a mismatch in any of these comparisons, it controls the alert device 86 to output an alert, which in this case specifically warns that the credit transaction has not been carried out correctly.

[0228] It should be noted that these fill transactions and credit transactions may be executed only when a game is not being played. In this case, the management device 84 recognizes the period after the game result is determined and all settlements are completed, and before the first playing card of the next game is drawn from the electronic shoe 94, as an inter-game period during which a fill transaction and a credit transaction may be performed. If the RFID tag 71 of the gaming chip 70 is read by the collection dealer antenna 5131 of the collection area 423a during this period, and the above-mentioned exchange conditions are not met, and the chip buy-in conditions described later are not met, the management device 84 recognizes that it is a fill transaction and activates the fill mode. Similarly, if the RFID tag 71 of the gaming chip 70 is read by the payout dealer antenna 5132 of the payout area 423b during the inter-game period, and the above-mentioned exchange conditions are not met, and the chip buy-in conditions described later are not met, the management device 84 recognizes that it is a credit transaction and activates the credit mode.

[0229] In a fill transaction and a credit transaction, the amount of gaming chips 70 to be filled or credited may be manually input by an operator and specified to the management device 84. In this case, the management device 84 determines whether the total amount of gaming chips 70 read in the collection area 423a or the payout area 423b is the specified amount.

[0230] (Chip buy-in) As explained in the first embodiment, a player can purchase gaming chips 70 at the cashier, and can also purchase gaming chips 70 from a dealer at the game table 42. The dealer receives cash from the player, inserts it into the cash slot 93, and gives gaming chips 70 equivalent to the cash to the player. At this time, the dealer places the gaming chips 70 to be paid out to the player in the payout area 423b, and the payout dealer antenna 5132 reads the RFID tag 71 of this gaming chip 70.

[0231] When the cash sensor 931 provided in the cash insertion slot 93 detects cash, it notifies the management device 84. The management device 84 receives the notification of the cash detection from the cash sensor 931 and starts the tip buy-in mode.

[0232] In the chip buy-in mode, the management device 84 determines the chip ID and total amount of the gaming chip 70 read by the payout dealer antenna 5132. The management device 84 further compares the chip ID and total amount of the gaming chip 70 removed from the chip tray 421 by this chip buy-in with the chip ID and total amount of the gaming chip 70 read by the payout dealer antenna 5132, and if there is a mismatch, controls the alert device 86 to output an alert.

[0233] The cash sensor 931 only detects the presence of cash in the cash insertion slot 93, but instead of this cash sensor 931, a function of determining the denomination (amount) and authenticity of the cash may be provided. In this case, the management device 84 may determine whether the total amount of cash detected by this cash sensor 931 matches the total amount of gaming chips 70 placed in the payout area 423b, and if there is a mismatch, may control the alert device 86 to output an alert. The cash paid by the player in chip buy-in may be recognized by the cameras 91, 92 and the image recognition device 83. In this case, too, the management device 84 may compare the recognized total amount of cash with the total amount of gaming chips 70 read in the payout area 423b to determine whether chip buy-in has been performed correctly.

[0234] Also, when chip buy-in is performed, cash is placed in the collection area 423a, the cameras 91 and 92 photograph the cash placed in the collection area 423a, and the amount of the cash may be recognized by the image recognition device 83. In this case, the management device 84 may compare the amount of cash recognized by the image recognition device 83 with the total amount of gaming chips 70 paid out to the payout area 423b and read by the payout dealer antenna 5132 to determine whether chip buy-in has been performed correctly.

[0235] (Modification) In the above-mentioned second embodiment, the collection area 423a and the payout area 423b are provided adjacent to each other, and these collection area 423a and the payout area 423b are located between the chip tray 421 and the betting areas 422a to 422e. Depending on the relationship between the distance between these areas and the strength of the electromagnetic waves output from the antennas provided in these areas, each antenna may read the RFID tag 71 of the gaming chip 70 in an area other than the corresponding area. For example, the collection dealer antenna 5131 may read the RFID tag 71 of the gaming chip 70 placed in the payout area 423b, and the payout dealer antenna 5132 may read the RFID tag 71 of the gaming chip 70 placed in the collection area 423a.

[0236] In order to prevent such interference or erroneous reading between areas, a jamming antenna may be provided in each area to block or distort electromagnetic waves from antennas in other areas. Alternatively, a shielding material may be provided between each area to block electromagnetic waves from other areas. Furthermore, reading may be performed by shifting the reading timing between adjacent areas. Furthermore, even if a jamming antenna or shielding material is not provided, the above-mentioned multiple antennas may be provided at intervals that do not cause interference or erroneous reading.

[0237] In the second embodiment, the first reader 81 reads using the chip tray antenna 514, the collecting dealer antenna 5131, and the dispensing dealer antenna 5132, and the second reader 82 reads using the multiple betting areas 422a to 422e, but the combination of antennas and readers is not limited to this. For example, a reader may be provided for each antenna, and all antennas may be controlled by one reader.

[0238] In particular, when the collecting dealer antenna 5131 and the dispensing dealer antenna 5132 are controlled by the same reading device, the reading device may alternately read the collecting area 423a and the dispensing area 423b by alternately using the collecting dealer antenna 5131 and the dispensing dealer antenna 5132. Also, when the collecting dealer antenna 5131 and the dispensing dealer antenna 5132 are controlled by separate reading devices, each reading device may independently read the collecting area 423a and the dispensing area 423b by independently using the collecting dealer antenna 5131 and the dispensing dealer antenna 5132.

[0239] In the above embodiment, the gaming chips 70 are placed in the collection area 423a and the payout area 423b, and the collection dealer antenna 5131 and the payout dealer antenna 5132 read the RFID tag 71 of the gaming chips 70 placed in the collection area 423a and the payout area 423b, but the collection dealer antenna 5131 and the payout dealer antenna 5132 may read the RFID tag 71 of the gaming chips 70 passing through the collection area 423a and the payout area 423b. In this case, for example, the dealer may take out the gaming chips 70 to be paid out to the player from the chip tray 421, position them in the payout area 423b while holding them in his / her hand, have the payout dealer antenna 5132 read them, and move them to the betting areas 422a to 422e as they are. Also, for example, the dealer may hold the gaming chips 70 to be collected from the betting areas 422a to 422e in his / her hand, place them in the collection area 423a, have the collection dealer antenna 5131 read them, and move them to the chip tray 421 as they are.

[0240] Furthermore, in the above embodiment, the management device 84 automatically recognizes that a currency exchange, fill transaction, credit transaction, or chip buy-in is being performed, but instead, the management device 84 may receive operational input from an operator (e.g., operation of a switch or button) and recognize that a currency exchange, etc. is being performed in response to that input.

[0245] In the above-mentioned fraud detection system, the chip tray is provided with a collection chip tray for collecting and temporarily storing chips bet by a losing player, and the image analysis device and the control device may compare the amount of chips that should be in the collection chip tray, calculated from the position, type and number of chips bet by the losing player, with the actual total amount of chips in the collection chip tray, and determine whether there is a difference between the total amount that should be in the collection chip tray and the actual total amount.

[0246] In the above cheating detection system, obtaining the actual total amount of chips in the chip tray after settlement at the end of the game through the image analysis device is: 1) When redemption for winning chips is complete, 2) When the cards used in the game are collected and discarded in the discard area of ​​the table, 3) When a predetermined button associated with the winning / losing result determination device is pressed, 4) When the marker indicating victory or defeat is replaced.

[0247] In the above-mentioned fraud detection system, when the control device determines that the actual total amount of chips recorded in the dealer's chip tray at the gaming table does not correspond to the increase or decrease in chips calculated from the chip amounts bet by all players and the win / loss result of the game, the game recording device may be configured to add an index or time to the captured video, or to identify and play back the chip collection or payment scene, so that the record of the game in which the difference occurred can be analyzed in the game recording device.

[0248] In the above-mentioned fraud detection system, the image analysis device or control device may be configured to be able to obtain information on the type, number and position of chips bet even if some or all of the chips placed on the gaming table are hidden by the blind spot of the camera.

[0249] In the fraud detection system, the control device 1) The position, type and number of chips bet at each playing position on the gaming table are grasped, and the winning / losing history of each player and the amount of chips obtained from the winning / losing results of each game are compared with statistical data of past games to extract a unique situation; or 2) A state in which the amount of bet chips when losing is smaller than the amount of bet chips when winning at a playing position on a gaming table is extracted as a unique situation by comparing it with statistical data of past games; The structure may be such that

[0250] In the above-mentioned fraud detection system, the control device may be capable of comparing and determining whether the amount of chips detected in the dealer's chip tray at the gaming table has increased or decreased after an exchange of bills for chips has been made, in accordance with the payment amount of the chips corresponding to the exchanged bills, or in accordance with the payment amount of the bills corresponding to the exchanged chips.

[0251] In the above fraud detection system, the control device may further be provided with a database that keeps a history of the exchange of bills and chips, and may be able to refer to the database on a regular or daily basis to compare and determine whether the amount of chips recorded in the dealer's chip tray at the gaming table has increased or decreased in accordance with the payment amount of chips corresponding to the exchanged bills, or the total payment amount of bills corresponding to the exchanged chips.

[0252] In the above-mentioned fraud detection system, the control device may be capable of identifying a player of a playing position extracted as the difference or peculiar situation via the image analysis device.

[0253] In the above-mentioned fraud detection system, the control device may have a warning function for notifying another gaming table of the presence of the specified player when the specified player leaves his / her seat and takes a seat at the other gaming table.

[0254] In the fraud detection system, the control device further comprises: 1) In each game, whether there is any movement of chips between the start of card withdrawal or the start of the game by the dealer and the display of the game result by the card distribution device; 2) After the end of each game, while the dealer is collecting the chips bet by the loser among the players, whether or not the loser has taken any chips; 3) After the end of each game, whether or not chips were added while the dealer was collecting the chips bet by the losing players. 4) After the end of each game, whether the dealer has paid out the winning chips of the players; 5) After the end of each game, whether the winner among the players has taken the chips that they had bet and the chips that they had paid; The device may be provided with a function for determining at least one of the above.

[0255] In the above-mentioned fraud detection system, the win / loss result determination device may be a card distributing device that distributes cards at the gaming table, or a control device that determines the win / loss result of each game from information from the image analysis device that reads the cards distributed at the gaming table with a camera.

[0256] According to the fraud detection system of this embodiment, it is possible to detect fraud in the collection and redemption of chips according to the outcome of a game.

[0257] Furthermore, according to the system of this embodiment, even if a card is bent due to squeezing by a player, which is often done in games such as baccarat, the rank and suit of the card can be determined by image analysis, and the total amount of blind spots and overlapping chips can be grasped together with their positions.Fraudulent transactions when exchanging bills and chips can also be detected.

[0258] The overall outline of the cheating detection system in a gaming parlor having a plurality of gaming tables according to this embodiment will be described in more detail below. FIG. 16 is a diagram showing the overall outline of the system, and the cheating detection system in a gaming parlor having a plurality of gaming tables 304 includes a game recording device 311 that records the progress of the game played at the gaming table 304 as an image via a plurality of cameras 302 including the player 306 and the dealer 305, an image analyzing device 312 that performs image analysis of the recorded image of the progress of the game, and a card distributing device 303 that judges and displays the winning or losing result of each game at the gaming table 304. The card distributing device 303 is a so-called electronic shoe that is already used by those skilled in the art, and is programmed with the rules of the game in advance, and is structured to be able to read the information of the cards C that are distributed and judge the winning or losing of the game. For example, in a baccarat game, the banker's win, the player's win, and a tie (draw) are basically determined by the ranks of two or three cards, and the judgment result (winning or losing result) is displayed by a result display lamp 313.

[0259] The cheating detection system further includes a control device 314 that compares the actual rank of the cards based on the image analysis result by the image analysis device 312 with the winning / losing result determined by the card distribution device 303 to detect cheating (such as a mismatch between the total rank of the cards distributed and the winning / losing result) performed at the gaming table 304. The card distribution device 303 is structured to be capable of reading the rank (A, 2-10, J, Q, K) and suit (heart, spade, etc.) of the card C manually distributed by the dealer 305, and the control device 314 is structured to be capable of collating the rank and suit information obtained by the image analysis device 312 (using artificial intelligence) from the image (taken using the camera 302) of each card distributed at the gaming table 304 with the card and suit information read by the card distribution device 303 to determine whether they match. The image analysis device 312 and the control device 314 in the cheating detection system are structured to be equipped with a computer, a program, and a memory, which are either integrated or composed of multiple components.

[0260] The image analysis device 312 and the control device 314 have an artificial intelligence or deep learning structure that can obtain information on the rank of a card C even if the card C is dealt at the gaming table 304 and is bent or soiled by the player 306. With a soiled card C, as shown in FIG. 18, a situation occurs in which it is difficult to distinguish between a club and a spade. Even in such a case, it is possible to distinguish the suit by analyzing and judging the image using an artificial intelligence computer or control system and deep learning (structure) technology. Even if the card is bent by squeezing the card by the player, which is often performed in a baccarat game or the like, it is possible to recognize the suit and rank of the card before the deformation by using self-learning of a large number of image deformations and the like using an artificial intelligence computer or control system and deep learning (structure) technology. Since the artificial intelligence computer or control system and deep learning (structure) technology are already known and available to those skilled in the art, detailed explanations are omitted.

[0261] The control device 314, which has an artificial intelligence or deep learning structure, can grasp, via the camera 302 and the image analysis device 312, on which position (player, banker, or pair) each player 306 has bet the chips 309 in the betting area 308, the type of chips 309 bet (each color of the chips 309 is assigned a different value), and the number of chips. The chips 309 may not be aligned vertically and may be stacked out of alignment. In this case, if the camera 302 is positioned so as to photograph the stacked chips from the side (or if the chips 309 are relatively oriented in a blind spot), it is assumed that the chips 309 will not be visible (will be in a blind spot). In an artificial intelligence-based computer or control system, or deep learning (structure) technology, a self-learning function or the like is used to recognize the chips 309 being hidden by a blind spot (when a part of a chip is hidden, or when the entire chip is hidden), and the number of chips, etc. can be accurately grasped. In this way, it is possible to grasp which position in the betting area 308 the chips 309 have been bet on (player, banker, or pair), the type of chips 309 bet (each color of chips 309 is assigned a different value) and the number of chips 309 bet.Therefore, according to the outcome of each game determined by the card distribution device 303, the control device 314 determines whether the collection of losing chips bet by each player 306 (as shown by arrow L) and the payment of winning chips (309W) to the winning player 306W have been properly carried out by analyzing the image of the game progress via the image analysis device 312.

[0262] The control device 314 can analyze and grasp the total amount of chips 309 in the chip tray 317 of the dealer 305 of the gaming table 304 using the image analysis device 312, and after the game is over and settled, can compare and calculate whether the total amount of chips 309 in the chip tray 317 has increased or decreased according to the result of the game, depending on the collection of the losing chips 309 bet by each player 306 and the amount of the payment 309W for the winning chips to the winning player 306W. Even if the total amount of chips 309 in the chip tray 317 is always grasped by means of RFID or the like, the control device 314 determines whether the increase or decrease is correct by analyzing the image of the game progress state via the image analysis device 312. These also utilize artificial intelligence or deep learning structures.

[0263] In this example, fraud or mistakes are detected based on the outcome of the game, information on how many of what type of chips 309 were bet and on which position (player, banker, or pair) in the betting area 308, and the increase or decrease in the amount of chips 309 in the chip tray 317 after the losing chips have been collected and the winning chips 309 have been redeemed. Therefore, fraud or mistakes can be detected without knowing the movement of the chips 309 after the game ends, i.e., whether the bet chips 309 have moved to the player's side or the dealer's side.

[0264] Here, in the case of baccarat, for example, the outcome of the game can be determined in accordance with the rules of baccarat by reading the rank of the card C played in the game in the card dealing device 303. The outcome of the game can also be determined by taking a picture of the game table 304 with the camera 302, analyzing the image with the image analyzing device 312, and comparing the analysis result with the game rules in the control device 314. In this case, the camera 302, the image analyzing device 312, and the control device 314 constitute a winning / losing result determining device. Information on the player at each play position 307, what type of chips 309, and how many chips have been bet on which position (player, banker, or pair) in the betting area 308 is obtained by taking a picture of the chips 309 placed in the betting area 308 with the camera 302 and analyzing the image for each play position 307 with the image analyzing device 312.

[0265] Also, the increase or decrease in the amount of chips 309 in the chip tray 317 before and after the collection of losing chips 309 and the redemption of winning chips 309 can be calculated by comparing the total amount of chips 309 in the chip tray 317 before the collection of losing chips 309 and the redemption of winning chips 309 with the total amount of chips 309 in the chip tray 317 after the collection of losing chips 309 and the redemption of winning chips 309. The total amount of chips 309 in the chip tray 317 before the collection of losing chips 309 and the redemption of winning chips 309 and the total amount of chips 309 in the chip tray 317 after the collection of losing chips 309 and the redemption of winning chips 309 can be detected by photographing the chip tray 317 containing the chips 309 with the camera 302 and analyzing the image with the image analyzer 312. Also, by embedding an RFID in chip 309 indicating the amount and providing chip tray 317 with an RFID reader, the total amount of chips 309 contained in chip tray 317 may be detected.

[0266] FIG. 17A is a diagram showing details of the chip tray of this embodiment, and FIG. 17B is a diagram showing another example of the chip tray. The chip tray 317 is provided with a collection chip tray 3171 for collecting and temporarily storing the chips 309L bet by the losing player 306L, and a redemption chip tray 3172 for storing the chips 309W to be redeemed. The image analysis device 312 and the control device 314 grasp the position, type, and number of the chips 309L bet by the losing player 306L, and calculate the increase in the chips 309L in the game (the amount of the chips 309 that should be in the collection chip tray 3171). Furthermore, the image analysis device 312 and the control device 314 grasp the actual total amount of the chips 309 in the collection chip tray 3171 after collection, and compare the actual total amount with the actual total amount to determine whether there is a difference.

[0267] In addition, by using the chips 309 in the redemption chip tray 3172 to redeem the chips 309W to the winning player 306W, it is possible to ensure that there is sufficient time for the image analysis device 312 and the control device 314 to determine the actual total value of the chips 309 in the collection chip tray 3171 after collection.

[0268] The gaming table 304 includes a discard area 341 and / or a discard slot 342 for discarding the cards C used in the game. Every time a game ends, the cards C used in the game are collected and discarded by placing them in the discard area 341 or the discard slot 342 on the gaming table 304.

[0269] As described above, in this embodiment, the control device 314 calculates the chip balance for each game from the amount of chips bet on the gaming table 304 and the winning or losing result of the game, and verifies the increase in the chip balance in the chip tray 317 after the game. If the control device 314 detects a discrepancy in this verification, it issues an alarm or adds a record to that effect to the video record captured by the camera 302. The casino operator can investigate the cause of the discrepancy by checking the video.

[0270] The fraud detection system of this embodiment adds or subtracts the increase or decrease in the amount of chips in a game, which is calculated from the positions, types and numbers of chips 309 bet by all players 306 in that game and the outcome of the game obtained by the win / loss result determination device, from the total amount of chips 309 in chip tray 317 before the settlement of each game, and compares the total amount of chips 309 that should be in chip tray 317 after settlement at the end of the game with the actual total amount of chips 309 in chip tray 317 at the end of the game obtained via image analysis device 312, and determines whether there is a difference between the actual total amount and the total amount that should be.

[0271] The control device 314 grasps the position, type and number of chips bet by each player via the image analysis device 312, and when all of the losing chips bet by each player have been collected, grasps the actual total amount of chips in the chip tray, and compares the total amount of chips 309 in the chip tray 317 that should be, calculated by adding the increase in the chip tray 317 for that game based on the position, type and number of chips bet by the losing player from the total amount of chips in the chip tray before the settlement of each game, with the actual total amount of chips 309 in the chip tray 317, and determines whether there is a difference between the actual total amount and the total amount that should be.

[0272] The control device 314 compares the total amount of chips 309 in the chip tray 317 before the settlement of each game, plus the increase in the chip tray 317 for that game based on the position, type and number of chips 309 bet by the losing player, with the actual total amount of chips 309 in the chip tray 317, and if it determines that there is no difference between the total amount that should be and the actual total amount, it compares the total amount that should be in the chip tray 317 after settlement at the end of the game with the actual total amount of chips 309 in the chip tray 317 at the end of the game obtained via the image analysis device 312, and if it determines that there is a difference between the total amount that should be and the actual total amount, it determines that a payment error has occurred and generates a payment error signal to notify of the payment error.

[0273] The chip tray 317 is provided with a collection chip tray 3171 for collecting and temporarily storing the chips 309 bet by the losing player, and the image analysis device 312 compares the total amount of the chips 309 that should be in the collection chip tray 3171, which is calculated by adding the increase in the amount of the chips 309 in the game calculated from the position, type and number of the chips 309L bet by the losing player, with the actual total amount of the chips 309 in the collection chip tray 3171, and determines whether there is a difference between the total amount that should be and the actual total amount.

[0274] When the control device 314 determines that the actual total amount of chips 309 grasped in the chip tray 317 of the dealer 305 of the gaming table 304 does not correspond to the increase or decrease in the amount of chips calculated from the chip amounts bet by all the players and the outcome of the game, the game recording device 311 can add an index or time to the captured video, or identify and play back the scene of collecting or paying out the chips 309, so that the game recording device 311 can analyze the record of the game in which the above-mentioned difference occurred.

[0275] In this way, the control device 314 obtains the total amount of chips in the chip tray 317 after settlement at the end of the game via the image analysis device 312. In this case, the determination after settlement is made when any of the following 1) to 4) occurs. 1) When the redemption for the winning chip 309 is completed, 2) When the card C used in the game is collected and discarded in the discard area 341 or the discard slot 342 of the table, 3) When a predetermined button associated with the winning / losing result determination device is pressed, 4) When the marker indicating victory or defeat is replaced.

[0276] The control device 314 is an artificial intelligence-based or deep learning-based control device that can grasp the position (position bet on player, banker, or pair) and amount (type and number) of chips bet at each play position 307 of the gaming table 304, and can extract the win / loss history and amount of chips (winning amount) of each player 306 obtained by the winning / losing result of each game as a unique situation (set by the casino) by comparing it with statistical data of many past games (big data). Typically, the control device 314 is equipped with an artificial intelligence-based or deep learning-based control device that can extract the occurrence of a winning amount of more than a certain amount (1 million dollars) or a situation in which the amount of bet chips when losing is small and the amount of bet chips when winning is large for several games in a row at a play position 307 of a certain gaming table 304 as a unique situation by comparing it with statistical data of past games (big data, etc.).

[0277] Furthermore, the control device 314 of the fraud detection system (integrated with the image analysis device 312) is configured to be able to identify an individual player 306 at a playing position 307 who has been extracted as a peculiar situation or who has won a predetermined amount or more. To identify such a player 306, the image analysis device 312 obtains an image of the face by extracting feature points or the like, and identifies the player by assigning an identity number (ID, etc.). When the identified player 306 leaves his / her seat and sits at another gaming table, the control device 314 has a warning function to notify the other gaming table of the presence of the specific player. Specifically, the control device 314 notifies a pit manager who manages each gaming table 304 or a person in charge of each table (which may be a dealer) to prevent further peculiar phenomena.

[0278] The control device 314 further includes a database that records the history of the exchange of banknotes K and chips 309, and refers to the database at regular intervals or daily intervals to determine whether the amount of chips 309 recorded in the chip tray 317 of the dealer 305 at the gaming table 304 has increased or decreased in accordance with the payment amount of the chips 309 corresponding to the exchanged banknotes K, or the total amount of the payment amount of the banknotes K corresponding to the exchanged chips 309.

[0279] In the above example, the winning / losing history and the amount of chips (winning amount) for each playing position 307 may be monitored without identifying each individual player 306. In this case, if each player 306 leaves his / her seat, the player 306 cannot be tracked, but it is possible to detect a peculiar situation, such as a situation in which the amount of bet chips when losing at a specific playing position 307 of one gaming table 304 is small and the amount of bet chips when winning is large for several consecutive games. If such a playing position 307 is detected, there is a suspicion of cheating or a mistake at that playing position 307. Then, cheating or a mistake can be discovered by verifying a video taken at that playing position 307.

[0280] Specifically, the camera 302 is installed so as to capture at least the chips 309 placed in the betting area 308 of the gaming table 304. The image analysis device 312 analyzes the image captured by the camera 302 to detect whether the chips are placed in the player, banker, or tie position in the betting area 308 for each playing position 307, and the amount of the placed chips. The card distribution device 303 also functions as a win / loss result determination device and determines the win / loss result of the game. The control device 314 records (monitors) the win / loss history and the amount of chips obtained (amount of chips obtained) for each playing position 307 based on the position (player, banker, or tie) in the betting area 308 where the chips 309 are placed and the win / loss result of the game. Note that only one of the win / loss history and the amount of chips obtained may be recorded. The control device 314 identifies the playing position 307 as a playing position suspected of fraudulent activity if the winning / losing history and / or chip winnings history are in a unique situation (set by the casino) compared to the statistical data of a large number of past games (big data).

[0281] When cheating is suspected at a certain play position 307, the cheating detection system may generate an alarm (light, sound, or vibration) that is perceptible at least to the dealer at that time. This makes it possible to at least suspend the game thereafter and prevent the cheating from continuing. Also, information indicating that cheating is suspected may be added to the video captured and recorded by the camera 302. This allows the cause of the suspected cheating to be identified by checking the video.

[0282] The cheating detection system in the gaming facility having the gaming table in this embodiment further includes a function of inspecting when exchanging bills and chips, which is often performed at the gaming table 304. In a gaming facility such as a casino, a player 306 exchanges bills (cash, etc.) for gaming chips at a predetermined chip exchange before a game. However, when the player 306 runs out of chips, the player 306 can continue the game by exchanging the cash (bills) for chips 309 on the gaming table (baccarat table, etc.) without leaving the gaming table 304. However, this creates an opportunity for cheating between the dealer 305 and the player. The exchange of cash (bills) for chips 309 on the gaming table (baccarat table, etc.) needs to be performed when the game is not in progress. The card distribution device 303 is capable of detecting the start of card dealing and the end of dealing (the time when the win or loss is determined) in order to determine the win or loss of the game. For this reason, the card dealing device 303 detects situations other than card dealing (dealing), and the control device 314 detects that bills are being exchanged for chips 309 on the gaming table 304 when cards are not being dealt (as shown in FIG. 19). When cards are being dealt (or other situations), they can be detected based on information obtained from the operation of the card dealing device 303 or the dealer 305.

[0283] The control device 314 can recognize the number and amount of bills by performing image analysis of the surface of the bills K. Furthermore, in the gaming table 304, whether or not the bills K to be exchanged for the chips 309 are genuine is judged by detecting the genuine mark G of the bill by irradiating it with a black light. As shown in FIG. 21, the control device 314 also performs image analysis and verifies the genuine mark G, recognizes the total amount of genuine bills, and further recognizes the total amount of chips even if multiple chips placed on the gaming table as exchange objects are hidden by the blind spot of the camera 302, and is an artificial intelligence-utilizing or deep learning structure that can compare the total amount of the bills K placed on the gaming table 304 by the player with the total amount of the chips 309 placed on the gaming table 304 by the dealer 305 and determine whether the amounts of the two match.

[0284] The control device 314 is an artificial intelligence-utilizing or deep learning structure capable of performing a comparative calculation as to whether the total amount of chips 309 in the chip tray 317 of the dealer 305 of the gaming table 304 has increased or decreased according to the payment amount of chips corresponding to the exchanged bills after the bills have been exchanged for chips and settlement. The total amount of chips 309 in the chip tray 317 of the dealer 305 may be always known in advance by the RFID of the chips 309 or the like. The total amount of chips 309 stored in the chip tray 317 can also be detected by photographing the chip tray 317 containing the chips 309 with the camera 302 and analyzing the image with the image analyzer 312.

[0285] Furthermore, the control device 314 verifies whether the increase or decrease in the value of the chips 309 in the chip tray 317 before and after the exchange of the bills for the chips matches the exchanged amount of the chips as a result of the image analysis on the gaming table 304. The amount of the paid bills may be input to the control device 314 by the dealer 305 via keystrokes or the like, or may be identified by taking an image of the gaming table 304 where the bills are paid using the camera 302 and analyzing the image using the image analyzer 312.

[0286] As described above, the control device 314 judges whether the amount of chips 309 deducted from the chip tray 317 due to the exchange of banknotes and chips matches the amount of banknotes paid by the player 306 to the dealer 305. Furthermore, the control device 314 is an intelligent control device that can compare and calculate whether the amount of banknotes deposited by the dealer 305 (usually by key input, etc.) matches the calculated amount of banknotes as a result of image analysis by the image analysis device 312 after the exchange of banknotes and chips has been made and the settlement is made, and may further be an artificial intelligence-utilizing or deep learning structure.

[0287] Furthermore, the control device 314 is an artificial intelligence-utilizing or deep learning structure capable of calculating and comparing whether or not the total amount of bills deposited at the gaming table 304 in charge of the dealer corresponds to the total amount of bills entered by the dealer and the total amount of bills as a result of image analysis by the image analysis device 312.

[0288] The control device 314 compares and determines whether the amount of chips 309 held in the chip tray 317 of the dealer 305 at the gaming table 304 has increased or decreased in accordance with the payment amount of the chips 309 corresponding to the exchanged banknotes, or the payment amount of the banknotes corresponding to the exchanged chips 309, after the banknotes and the chips 309 have been exchanged.

[0289] The control device 314 further has the following functions 1) to 5) to determine whether or not any cheating that violates the rules is taking place according to the rules of the baccarat game. 1) In each game, from the signal from the card dealing device 303 indicating that the withdrawal of cards should begin, or from the game start operation in which the dealer 305 presses the start button, until the result of the game is displayed by the card dealing device 303, the image analysis device 312 uses the camera 302 to monitor for any movement of the chips 309 (as shown in FIG. 16). 2) After each game ends, while the dealer 305 is collecting the chips 309 bet by the losers among the game participants 306 (as shown in FIG. 20), the image analyzer 312 monitors whether the loser 306L has illegally taken the chips 309 by using the information obtained by the camera 302. 3) After each game ends, while the dealer 305 is collecting the chips 309 bet by the losers among the game participants, the image analyzer 312 monitors, using information obtained by the camera 302, whether anyone other than the dealer 305 (winner or loser) adds winning chips 309W or places new chips 309 on the winning side where no chips have been bet. 4) After each game is over, the dealer 305 correctly places the payout chip 309W at the position of the chip 309 bet by the winning player among the game players 306 (as shown in FIG. 21), based on information obtained by the image analysis device 312 using the camera 302. 5) After each game is over (the dealer 305 operates the card distribution device 303 to display the winning or losing result on the display lamp 313), whether or not the winner 306W among the game participants 306 has taken the bet chips 309 and the paid chips 309W (as shown in FIG. 22) is monitored based on information obtained by the image analysis device 312 using the camera 302.

[0290] The control device 314 analyzes the information obtained by the image analysis device 312 using the camera 302 as follows. That is, by using the analysis results of the image analysis device 312 to detect the hand movements, chip movements, or the hand movements and chip movements of the dealer 305 and the game participants 306, the above 1) to 5) are monitored, but the basic analysis requires at least knowing who has taken the chips 309. The analysis method will be explained below with reference to Figures 23 to 25.

[0291] Analysis of the dealer 305 taking the chips 309 bet by the game participant 306L (Fig. 23). The dealer 305 collects the chips 309 bet by the game participant 306L who lost the game. Whether or not the chips are collected is monitored by analyzing information obtained by the image analyzer 312 using the camera 302. First, a change from a state in which the bet chips 309 are present (Fig. 27A) to a state in which they are not present (Fig. 23C) is detected by image analysis. Then, an image (Fig. 23B) between a state in which the chips 309 are present and a state in which they are not present is analyzed. In the image (Fig. 23B) between a state in which the chips 309 are present and a state in which they are not present is analyzed, and cheating is detected based on the following rule: if the hand 305h is extending from above (or the hand movement in which the hand appears from above and then recedes above), the hand 305h is judged to be that of the dealer 305, and if the hand is extending from any other direction, cheating is judged.

[0292] While the dealer 305 is collecting the chips 309 bet by the game participant 306L who lost the game, the system monitors whether or not other players are taking the lost chips 309 in an illegal manner (Figs. 23 and 26). In an image between a state where the chips 309 are present and a state where they are not, as shown in Fig. 24, the analysis of the taking by the loser 306L or the like of the game participants 306 is performed by detecting by image analysis that the hand 306h extends or moves from the bottom of Fig. 24 (originally from the top), and it is determined that this means that the hand 306h or the like other than the dealer 305 is taking the chips 309, and this is determined to be cheating.

[0293] Analysis of the fact that the dealer 305 correctly paid (placed) chips 309 for the winning chips 309, and that the winner 306W of the game participants 306 took them. First, the winning chips shown in FIG. 25A are redeemed for the chips 309W according to the rules of the game, as shown in FIG. 25B. A change from the state shown in FIG. 25A to the state shown in FIG. 25B is detected, and at the same time, it is detected by image analysis whether the hand is the dealer's 305 hand 305h. After this, as shown in FIG. 25C, the hand 306h of the winner 306W of the game participants 306 then extends (moves) to the same betting area, and the control device 314 checks whether all the chips 309 are then lost (as shown in FIG. 25D) according to the image analysis results, according to the rules of the game, to determine whether there was any cheating.

[0294] Furthermore, the control device 314 is configured to determine whether the amount of chips paid by the dealer 305 to the winner is correct based on the amount bet by the winner 306W of the game participants 306. A specific example is shown below. It is assumed that the position and total amount of the chips 309 (whether the chips 309 were bet on the player's or the banker's betting area 308) cannot be read normally, for example, when the chips 309 are shifted and overlapped, or when they are in a blind spot from the position of the camera 302. The control device 314 is configured to recognize the hiding of the chips 309 due to a blind spot (when a part of a chip is hidden, or when the entire chip is hidden) by using a self-learning function based on an existing artificial intelligence-based computer or control system, deep learning (structure) technology, etc., and to accurately grasp the position, number, etc. Furthermore, the structure for detecting the position and type of the chips 309 in the betting area 308 is not limited to this, and may be configured to detect by reading, for example, an ID embedded in the chip.

[0295] As described above, the control device 314 is able to grasp the position (position for betting on player, banker, or pair) of the chips 309 bet by each player 306 through the camera 302 and the image analysis device 312, as well as the type (each color of chip 309 is assigned a different value) and number of chips, and can detect which customer 306 bet on the player (if there are multiple customers 306 who bet on the player, which customer 306 bet the most) and which customer 306 bet on the banker (if there are multiple customers 306 who bet on the banker, which customer 306 bet the most).

[0296] Furthermore, the control device 314 of the cheating detection system of this game analyzes and monitors the information obtained by the image analysis device 312 using the camera 302 in the above manner, following the rules of the baccarat game. The monitoring shown in 1) to 5) above is performed to determine whether or not cheating that violates the rules is occurring. When cheating is detected, the control device 314 turns on the abnormality display lamps provided on both the card distribution device 303 and the gaming table 304, and outputs the detection of cheating to the casino management department or the like via wireless or wired communication. A monitor or lamp that issues a warning or display in response to the determination result may also be provided in another location.

[0297] As described above, fraudulent behavior is detected by the control device 314, and at the time of detection or at an appropriate time, an indication signal is displayed on the indicator lamp 313 or an abnormality indicator lamp of the card distributing device 303, or a warning is issued.In addition, after the fraud or error is detected, a function of the card distributing device 303 that prevents the distribution of cards may be activated to prevent the distribution of cards.

[0298] In the above embodiment, the image analysis device 312 and the control device 314 are devices that utilize artificial intelligence or have a deep learning structure. Specifically, the image analysis device 312 and the control device 314 may use a scale-invariant feature transform (SIFT) algorithm, a convolutional neural network (CNN), deep learning, machine learning, or the like to perform image analysis and the above various controls. These technologies are technologies that recognize objects contained in a captured image by performing image recognition, and in particular, in recent years, objects have been recognized with high accuracy using deep learning technology that multi-layers neural networks. This deep learning technology generally recognizes objects with high accuracy by stacking layers over multiple stages in an intermediate layer between the input layer and output layer of a neural network. In this deep learning technology, in particular, a convolutional neural network has attracted attention because it has higher performance than conventional methods of recognizing objects based on image features.

[0299] In a convolutional neural network, labeled target images are trained and the main objects contained in the target images are recognized. If there are multiple main objects in the training image, they are designated by rectangular regions, and the image corresponding to the designated region is labeled for training. Furthermore, the convolutional neural network can determine the main object in the image and the position of the object.

[0300] To further explain the convolutional neural network, the target recognition process extracts candidate regions based on local features by performing edge extraction processing on the recognition target image, inputs the candidate regions into the convolutional neural network to extract feature vectors, classifies them, and obtains the most certain classified candidate region as the recognition result. The certainty is an amount that indicates how high the similarity of the subject of an image learned together with a certain image region and label is relative to the similarity of other classes.

[0301] In addition, devices utilizing artificial intelligence or having a deep learning structure are described in U.S. Patent No. 9,361,577, U.S. Patent Publication No. 2016-171336, U.S. Patent Publication No. 2015-036920, Japanese Patent Publication No. 2016-110232, etc., the descriptions of which are incorporated herein by reference.

[0302] [Fourth embodiment: Management of gaming chip owners] The fourth embodiment of the present invention will be described below. This embodiment relates to a system that constantly grasps and manages information on the holder of each gaming token, and when a dealer pays the gaming token to a player and the holder of the gaming token is transferred from the casino to a player, makes it possible to grasp and record which player the possession of the gaming token has been transferred to. The fourth embodiment can be used in combination with the second embodiment.

[0303] (First example) FIG. 26 is a diagram showing the configuration of a management system of a first example of the fourth embodiment of the present invention. In the management system 110, the holder of the gaming token is traced without using a database. For this purpose, information on the holder is stored in the gaming token. The management system 110 is provided with a gaming table 4004 having a roughly oval shape. The player 282 is positioned on one side (the lower side of FIG. 26) of the gaming table 4004, and the dealer (not shown) is positioned on the opposite side. On the upper surface of the gaming table 4004, betting areas 422a to 422e (hereinafter, collectively referred to as "betting areas 422") are partitioned for each of a plurality of play positions. The betting area 422 is an area for the player 282 to place a bet by placing the gaming token 283. On the dealer position side of the gaming table 4004, a chip tray 212 for placing the dealer's gaming token 283 is provided.

[0304] The gaming token 283 has the same configuration as the gaming token of the above embodiment. That is, an RFID tag having a non-rewritable area for storing fixed information and a rewritable area for storing variable information is embedded in the gaming token 283. A chip ID (identification information) that uniquely identifies the gaming token 283 is stored in the RFID tag as fixed information. In addition, a user ID that uniquely identifies the holder of the gaming token 283 is stored in the RFID tag as variable information.

[0305] In addition, the casino or dealer is assigned a common user ID, and when the gaming token 283 is in the casino's possession (including when it is stored in the chip tray 212), the variable information stores the user ID indicating the casino or dealer.

[0306] RFID antennas 515a to 515e (hereinafter collectively referred to as "RFID antennas 515") are provided in the betting areas 422a to 422e of the gaming table 4004. Specifically, the RFID antennas 515 are embedded under the cover of the gaming table 4004 at positions where the corresponding betting areas 422 are defined. Also, an RFID antenna 514 is provided in the chip tray 212.

[0307] The RFID antenna 515 reads and writes data from the RFID tag embedded in the gaming token 283 placed in the corresponding betting area 422. The RFID antenna 514 reads and writes data from the RFID tag embedded in the gaming token 283 placed in the chip tray 212.

[0308] The RFID antennas 515a to 515e and the RFID antenna 514 are connected to the RF control device 254. In FIG. 26, only the line connecting the antenna 515e and the RF control device 254 is shown, and the lines connecting the antennas 515a to 515d and the RF control device 254 are omitted for clarity of the figure, but the antennas 515a to 515d are also connected to the RF control device 254 like the antenna 515e. This is the same in the following drawings. The RF control device 254 controls reading and writing for each antenna. The RF control device 254 controls reading and writing by distinguishing each antenna. For this reason, an area ID that uniquely identifies the area where the antenna performs reading and writing is assigned to each antenna. In addition, when the RF control device 254 performs reading, it performs reading periodically.

[0309] By referring to this area ID, it is possible to identify whether the read gaming token 283 is in the chip tray 212 or in the betting area 422, and for the betting area 422, it is also possible to identify which of the betting areas 422a to 422e the read gaming token 283 corresponds to.

[0310] When reading, the RF control device 254 receives data read by each antenna and specifies the area in which the data was read, i.e., the area ID. When writing, the RF control device 254 specifies the antenna to perform writing, i.e., the area ID, and transmits the data to be written. This allows the RF control device 254 to individually control reading and writing for each antenna.

[0311] The RF control device 254 outputs the user ID of the gaming token 283 ("User ID" in FIG. 26) and the area ID of the area from which the user ID was read ("Area ID" in FIG. 26) based on the data read by each antenna. The management system 110 further includes a management control device 256 connected to the RF control device 254. The management control device 256 receives the user ID and area ID from the RF control device 254, and specifies to the RF control device 254 the user ID to be written to the RFID tag.

[0312] As described below, the user ID stored in the RFID tag of the gaming token 283 changes when the gaming token 283 is moved, but the RFID tag stores past user IDs as variable information in addition to the latest user ID. Therefore, by referring to this variable information, it is possible to check the change in the owner of each gaming token 283. In the following description, expressions such as "rewrite user ID" mean at least changing the latest user ID, and do not necessarily mean erasing information on past user IDs at the same time.

[0313] The management control device 256 updates the fluctuation information of the gaming token 283 based on the data (user ID and area ID) of the gaming token 283 received from the RF control device 254. A method of updating the fluctuation information will be described below.

[0314] 27 to 29 are diagrams for explaining an example of updating variable information. As shown in Fig. 27, a player bets a gaming token 831 in the betting area 422b. The management control device 256 receives the user ID of the betting chip 831 and the area ID of the betting area 422b obtained by reading the RFID tag of the gaming token (hereinafter also referred to as "betting chip 831") bet by the player in the betting area.

[0315] At the stage of placing a bet, as shown in Fig. 27, the same user ID ("P1" in the example of Fig. 27) is read from the bet area 422b, and the same ID ("D" indicating that the holder is the casino or dealer in the example of Fig. 24) is also read from the chip tray 212. If this player wins the game, as shown in Fig. 28, gaming tokens (hereinafter also referred to as "payout chips 832") are paid out (redeemable) from the chip tray 212 by the dealer and placed next to the bet chips 831 in the bet area 422b.

[0316] Then, "D" is read from the betting area 422b as the user ID in addition to "P1". When there are two types of user IDs of the gaming tokens 283 read from the same betting area 422, one of which is "D" and the other is a user ID assigned to a player, the management control device 256 controls the RF control device 254 to rewrite the user IDs of all the gaming tokens 283 in the betting area 422 to the user ID assigned to the player ("P1" in the case of FIG. 28). In this case, the same "P1" is further written as the latest user ID to the betting chip 831 in which "P1" was stored as the user ID.

[0317] On the other hand, when the player loses the game, the dealer collects the bet chips 831 into the chip tray 212 as shown in Fig. 29. Then, in addition to "D", "P1" is read from the chip tray 212 as the user ID. If the user ID of the gaming token 283 read from the chip tray 212 includes a user ID assigned to the player other than "D" ("P1" in the example of Fig. 29), the management control device 256 rewrites the user ID of all the gaming tokens 283 in the chip tray 212 to "D".

[0318] In addition, a collection float may be provided to temporarily store the gaming tokens 283 collected in the chip tray 212, and the antenna may be separated between the collection float and other parts, so that the above processing is performed only on the gaming tokens 283 collected on the collection float.

[0319] The above-mentioned processing of the management control device 256 updates the user ID stored in the gaming token 283 in response to a change in the actual holder. That is, in this embodiment, the user ID is stored in the RFID tag of the gaming token 283, and the user ID of the payout chip 832 is updated so that the holder is the same as the holder of the bet chip 831. Therefore, without using a database or a player identification system described later, and without the management control device 256 grasping the progress of the game (betting stage, game stage, settlement stage), it is possible to trace the change in the holder due to the game played on the gaming table 4004.

[0320] When a player purchases a new gaming token 283, the player is identified using a player identification system described later, and the user ID of the casino or dealer is rewritten to the user ID of the identified player before the gaming token 283 is handed over to the player. Also, when the player exchanges the gaming token 283 for cash, the user ID of the gaming token 283 handed over by the player is rewritten to the user ID of the casino or dealer.

[0321] (Second example) 30 is a diagram showing the configuration of a management system of a second example of the fourth embodiment. In addition to the configuration of the management system 110 of the first example, a player identification system is introduced into the management system 120. The player identification system includes an image recognition system consisting of a camera 252 and an image recognition device 255, and a card authentication system consisting of a card 281 and a card reader 253, but may be either one of them.

[0322] The camera 252 photographs the face of the player 282 positioned at the play position, and outputs the image generated by photographing to the image recognition device 255. The image recognition device 255 is equipped with a face recognition engine using a neural network that has learned face images of a plurality of players 282 (hereinafter, the registered players are also referred to as "members") who have been registered in advance. The image recognition device 255 inputs the image from the camera 252 into the neural network, thereby identifying which registered member the input face image belongs to. If the image recognition device 255 determines that the image from the camera 252 does not belong to any of the registered members, it outputs a result indicating that the face image belongs to a non-member.

[0323] Furthermore, the image recognition device 255 identifies the play position of the member based on the position in the image where the face was authenticated. The image recognition device 255 outputs the area ID of the identified play position ("Area ID" in FIG. 30) together with the user ID of the member corresponding to the image from the camera 252 ("User ID" in FIG. 30). Note that if the image recognition device 255 cannot identify which member the member is, it outputs "Unknown" as the user ID.

[0324] The card reader 253 scans the member's card 281 handed to the dealer by the player 282, and reads the information stored in the member's card 281. The member's card 281 is a magnetic card on which a magnetic stripe is formed, and at least the user ID of the player 282 (member) is stored in the magnetic stripe. When the dealer receives the member's card 281 from the player 282, the dealer scans the member's card 281 using the card reader 253, and inputs the playing position of the player 282 into the card reader 253. The card reader 253 outputs the user ID ("User ID" in FIG. 30) read from the member's card 281 and the area ID ("Area ID" in FIG. 30) of the playing position input by the dealer.

[0325] The management control device 256 receives the user ID and area ID stored in the gaming token 283 and read using the antenna 515 from the RF control device 254, receives the user ID and area ID identified based on the player's facial image from the image recognition device 255, and receives the user ID obtained by reading the member's card 281 from the card reader 253 and the area ID specified by the dealer.

[0326] For the same area ID, if the user ID read from the antenna 515, i.e., the user ID stored in the gaming token 283 bet in the betting area 422 as the holder of the gaming token 283, does not match the user ID read from the member's card 281 or the user ID identified by the image recognition device 255, i.e., the player identified by the player identification system, the management control device 256 controls the RF control device 254 to rewrite the user ID stored in the rewritable area of ​​the gaming token 283 bet in the betting area 422 as the holder to the user ID of the player identified by the player identification system.

[0327] The RF control device 254 uses the antenna 515 to write the user ID of the player identified by the player identification system in the rewritable area of ​​the RFID tag of the gaming token 283 placed in the betting area 422. At this time, the RF control device 254 also records in the rewritable area that the user ID has been rewritten as holder information due to a mismatch in the user ID. This allows the casino or dealer, when acquiring the gaming token 283, to know that there has been a mismatch in the holder by referring to the history of holder changes, and also allows the player involved in such a mismatch to be identified.

[0328] In addition, in the player identification system, only one of the following may be performed: identification of a player by the face authentication system or identification of a player by reading the member's card 281. In other words, a registered member does not necessarily need to identify the player by the member's card 281 when he or she arrives at the play position, in which case the player is identified only by the face authentication system. Also, even if the face of the player cannot be photographed well and face authentication cannot be performed, the player may be identified by the member's card 281.

[0329] Furthermore, a player may be identified by both face authentication and the member's card 281. In this case, the user ID of the player identified by face authentication may differ from the user ID of the player identified by the member's card 281. If either one of the user IDs matches the user ID read from the gaming token 283, the management control device 256 controls the RF control device 254 to record, in the rewritable area of ​​the gaming token 283, the user ID that does not match the user ID read from the gaming token 283, as well as the fact that there was a mismatch in the identification of the player by the player identification system.

[0330] In this example, as in the first example, the user ID stored in the gaming token 283 is updated according to the actual holder. Furthermore, in this example, when the user ID of the player identified by the player identification system does not match the user ID stored in the gaming token 283, the mismatch is corrected and the occurrence of such a mismatch is recorded in the gaming token 283. Therefore, by referring to this record of the gaming token 283, it is possible to know that the gaming token 283 has been handed over between players, and to identify the players involved in the exchange.

[0331] When exchanging the gaming token 283 for cash, a player identification system similar to that described above may be used so that if the user ID of the player (user attempting to exchange) identified by face recognition or the member's card 281 differs from the user ID stored in the gaming token 283 to be exchanged for cash, an alarm to that effect may be output and the operator may not approve the exchange.

[0332] (Third example) FIG. 31 is a diagram showing the configuration of a management system of a third example of the fourth embodiment. The management system 130 includes a database 57 in addition to the configuration of the management system 110 of the first example. The database 57 stores a chip ID ("Chip ID" in FIG. 31) that uniquely identifies the gaming token 283 and a user ID of a player who possesses the gaming token 283 in association with each other. As described above, the holder of the gaming token 283 changes when the gaming token 283 is purchased, used in a game, and exchanged for cash, but the database 57 records the history of past holders. Therefore, by referring to the database 57, it is possible to know the change in the holder of each gaming token 283.

[0333] In this example, the gaming token 283 only needs to have a non-rewritable area, and does not need to have a rewritable area. That is, at least the chip ID needs to be stored in the gaming token 283. Also, the RF control device 254 does not need to have a writing function, and may be an RF reader having only a reading function.

[0334] The management control device 256 updates the database 57 based on the data (chip ID and area ID) of the gaming token 283 received from the RF control device 254. A method of updating the database 57 will be described below.

[0335] 32 to 34 are diagrams for explaining an example of updating the database 57. As shown in Fig. 32, a player bets gaming tokens 831 in the betting area 422b. The chip ID of the betting chip 831 and the area ID of the betting area 422b obtained by reading the RFID tag of the betting chip 831 bet by the player in the betting area 422b are input to the management control device 256.

[0336] At the stage of placing a bet, as shown in FIG. 32, "C00001" to "C00005" are read as chip IDs from the bet area 422b, and "C20001" to "C20100" are read as chip IDs from the chip tray 212. Then, the RF control device 254 outputs a set of the chip IDs read by the antennas 515 and 514 and the area IDs corresponding to the antennas 515 and 514 to the management control device 256. In the example of FIG. 32, the RF control device 254 obtains combinations of the chip IDs "C00001" to "C00005" and the area ID "Area 2", and combinations of the chip IDs "C20001" to "C20100" and the area ID "Area T" (area ID representing the chip tray 212), and outputs these to the management control device 256.

[0337] 33, the dealer pays out (redeems) the payout chips 832 from the chip tray 212 and places them next to the bet chips 831 in the bet area 422b. Then, the RF control device 254 obtains combinations of chip IDs "C00001" to "C00005" and "C20001" to "C20005" with the area ID "Area 2", and combinations of chip IDs "C20006" to "C20100" with the area ID "Area T", and outputs these to the management control device 256.

[0338] The management control device 256 refers to the database 57 for all the read chip IDs and obtains the user ID associated with the chip ID. Then, the management control device 256 refers to the combination of the chip ID and the area ID obtained from the RF control device 254, and if the user IDs are different for multiple chip IDs associated with the same area ID, updates the database 57 so that those user IDs become the same user ID.

[0339] Specifically, when the user IDs of multiple gaming tokens 283 read with the area ID of the same betting area 422 include a player's user ID and a casino or dealer's user ID, the management control device 256 unifies the user IDs of the chip IDs paired with the same area ID by rewriting the casino or dealer's user ID to the player's user ID.

[0340] On the other hand, when the player loses the game, the dealer collects the bet chips 831 into the chip tray 212, as shown in Fig. 34. Then, in addition to "C20001" to "C20100", "C00001" to "C00005" are read as chip IDs from the chip tray 212. The RF control device 254 obtains pairs of the chip IDs "C20001" to "C20100" and "C00001" to "C00005" and the area ID "Area T" of the chip tray 212, and outputs them to the management control device 256.

[0341] The management control device 256 refers to the database 57 for all the read chip IDs and obtains the user ID associated with the chip ID. Then, the management control device 256 refers to the combination of the chip ID and the area ID obtained from the RF control device 254, and if the user IDs are different for multiple chip IDs paired with the same area ID, updates the database 57 so that those user IDs become the same user ID.

[0342] Specifically, when the user IDs of multiple gaming tokens 283 read by the area ID of the chip tray 212 include a player's user ID and a casino or dealer's user ID, the management control device 256 rewrites the player's user ID to the casino or dealer's user ID, thereby making the user IDs of all chip IDs associated with the area ID of the chip tray 212 the casino or dealer's user ID.

[0343] By the above-mentioned processing of the management control device 256, the user ID stored in the database 57 is updated according to the actual holder. That is, in this embodiment, the database 57 is rewritten so that the gaming tokens 283 associated with different user IDs in the same area are unified to one of the user IDs according to the area. Therefore, without using the above-mentioned player identification system, and without the management control device 256 grasping the progress of the game (betting stage, game stage, settlement stage), it is possible to trace the change of holders due to the game played on the gaming table 4004.

[0344] Also, in the above example, the management control device 256 determines that the payout chip 832 is a payout chip 832 based on the fact that it is read in the bet area 422 and that the user ID in the database 57 is "D", and rewrites the user ID to the player's user ID, but instead, the chip ID of the payout chip 832 may be identified based on the difference between the chip IDs read from the chip tray 212 before and after payout.

[0345] For example, in the examples of Figures 32 and 33, before dispensing, as shown in Figure 32, the chip IDs "C20001" to "C20100" are read from the chip tray 212, whereas after dispensing, as shown in Figure 33, the chip IDs "C20006" to "C20100" are read from the chip tray 212. Therefore, from this difference, the management control device 256 can determine that the chip IDs "C20001" to "C20005" have been dispensed.

[0346] (Example 4) FIG. 35 is a diagram showing the configuration of a management system of a fourth example of the fourth embodiment. In addition to the configuration of the management system 110 of the first example, the management system 140 includes a player identification system, a database 57, and a card distribution device (electronic shoe) 4003. In addition, the gaming table 4004 is provided with pay areas 424a to 424e (hereinafter, collectively referred to as "pay areas 424") on the dealer side of the betting areas 422 of each play position. In addition, the pay areas 424a to 424e are provided with antennas 516a to 516e (hereinafter, collectively referred to as "antennas 516") corresponding to the respective areas.

[0347] When the dealer pays out (redeems) the gaming tokens 283 to the player 282 who has won the game, the dealer positions the gaming tokens 283 taken out from the chip tray 212 in the pay area 424 of the winning player 282 and then places it in the betting area 422 of that player 282.

[0348] The camera 252 in this example photographs not only the player 282 but also the bet chips 831 bet in the bet area 422. The image recognition device 255 performs image recognition processing not only on the player's face but also on the bet chips 831 in the bet area 422, recognizes which bet object (player, banker, tie, player pair, banker pair, etc.) in the bet area 422 the bet chips 831 in each bet area 422 are bet on, and outputs the recognition result as the bet content ("Betting" in FIG. 35).

[0349] The camera that photographs the face of the player 282 and the camera that photographs the betting chip 831 may be separate cameras. Also, the image recognition device that identifies the player based on the image of the player's face and the image recognition device that recognizes the betting details based on the image of the betting chip 831 may be separate devices.

[0350] In this example, the card dealing device 4003 determines the progress of the game (i.e., betting, playing, or settlement) and outputs the result to the RF control device 254. The card dealing device 4003 determines that the game has started when the first card is drawn, and determines that the game has ended based on the reading result of the drawn card according to the game rules of baccarat. Also, the card dealing device 4003 determines that settlement has ended and betting has started when the game start button is pressed.

[0351] Moreover, the card dealing device 4003 reads at least the rank of the drawn cards and determines the game result, such as a player win, a banker win, a tie, a player pair, or a banker pair, in accordance with the rules of the baccarat game.

[0352] The management control device 256 determines which play position will receive a payout based on the bet details obtained from the image recognition device 255 and the game result obtained from the card distribution device 4003. The management control device 256 further obtains the user ID of the player for each play position from the image recognition device 255 and the card reader 253, and determines which player will receive a payout based on this information as well.

[0353] The RF control device 254 activates the antenna 516 in the pay area 424 to read and write to the RFID tag of the gaming token 283 when the game progress status received from the card distribution device 4003 is being settled.

[0354] The management control device 256 refers to the database 57, and if the user ID associated with the chip ID of the payout chip 832 read in the pay area 424 is the user ID of the casino or dealer, it rewrites that user ID with the user ID associated with the chip ID of the bet chip 831 placed in the corresponding bet area 422 at that time.

[0355] When the dealer collects the bet chip 831 of a losing player, the antenna 516 of the pay area 424 may read the chip ID of the bet chip 831. In this case, the chip ID read in the pay area 424 will match the chip ID read in the immediately preceding corresponding bet area 422. This will enable the dealer to determine that the chip ID was read in the pay area 424 at the time of collection, and in this case, the user ID of the gaming token 283 read in the pay area 424 will not be rewritten.

[0356] In this example, the management system 140 has been described as including a player identification system, a database 57, and a card distribution device (electronic shoe) 4003. However, as in the first example, in a management system that does not include a player identification system, a database 57, and a card distribution device (electronic shoe) 4003, a pay area 424 and a corresponding antenna 516 may be provided as in this example, and user IDs may be updated.

[0357] In the management system 140 of this example, a pay area 424 is provided and is distinguished from the betting area 422, and the RFID tags of the gaming tokens 283 are read and written in the payout chips 832 dispensed from the chip tray 212, so that the payout chips 832 can be read and written at high speed. That is, as in the above first to third examples, if the payout chips 832 are read and written using the same antenna 516 as the betting chips 831, it is necessary to read and write the betting chips 831 in order to read and write the payout chips 832, which takes time. However, in the pay area 424, since it is necessary to read and write only the payout chips 832, reading and writing can be performed in a relatively short time, and there is no significant disruption to the operation of the game.

[0358] (Fifth Example) Fig. 36 is a diagram showing the configuration of a management system of a fifth example of the fourth embodiment. The management system 150 has the same configuration as the management system 140 of the fourth example shown in Fig. 35. That is, the management system 150 includes a player identification system, a database 57, and a card distribution device (electronic shoe) 4003 in addition to the configuration of the management system 110 of the first example.

[0359] The camera 252 in this example photographs not only the player 282 but also the bet chips 831 bet on the bet area 422. The image recognition device 255 performs image recognition processing not only on the player's face but also on the bet chips 831 in the bet area 422, recognizes which bet object (player, banker, tie, player pair, banker pair, etc.) in the bet area 422 the bet chips 831 in each bet area 422 are placed on, and outputs the recognition result as the bet content ("Betting" in FIG. 33).

[0360] The camera that photographs the face of the player 282 and the camera that photographs the betting chip 831 may be separate cameras. Also, the image recognition device that identifies the player based on the image of the player's face and the image recognition device that recognizes the betting details based on the image of the betting chip 831 may be separate devices.

[0361] The card dealing device 4003 determines game results, including player win, banker win, tie, player pair, and banker pair, according to the rules of the baccarat game by reading at least the ranks of the cards drawn in sequence.

[0362] The management control device 256 determines which play position will receive a payout (redemption) based on the bet details obtained from the image recognition device 255 and the game result obtained from the card distribution device 4003. The management control device 256 further obtains the user ID of the player for each play position from the image recognition device 255 and the card reader 253, and therefore determines which player will receive a payout (redemption) based on this information as well.

[0363] The management control device 256 receives, for each bet area 422, a pair of the area ID of the bet area 422 and the chip ID of the bet chip 831 read in the bet area 422 from the RF control device 254. As described above, the management control device 256 determines which play position will receive a payout, and therefore refers to the database 57 to obtain the user ID associated with the chip ID read in the play position that will receive a payout, and updates the user ID associated with the chip ID of the payout chip 832 to be paid out with the obtained user ID.

[0364] The management control device 256 recognizes the chip ID that is no longer read from the chip tray 212 before and after the payout as the chip ID of the payout chip 832. When there are multiple players to receive payouts, the dealer pays out in order from the edge in a predetermined direction (for example, payouts are made in order from the edge on the right hand side of the dealer to the edge on the left hand side). This makes it possible to determine to which play position or player the payout chip 832 removed from the chip tray 212 is to be paid out, even when there are multiple players to receive payouts.

[0365] In addition, since the management control device 256 can determine the playing position of the losing player, it updates the database 57 so that the user ID associated with the chip ID read from the bet area 422 of that playing position is set to "D", which represents the casino or dealer.

[0366] As described above, in this example, the management control device 256 can determine which player or play position's bet chips 831 are paid out and which player or play position's bet chips 831 are collected by grasping the bet contents and the game result, and can also identify the chip IDs of those bet chips 831 and payout chips 832, so that it can determine which user ID should be changed and which user ID should be changed to, in the database 57. This makes it possible to trace the holder of the gaming token 283.

[0367] (Example 6) 37 is a diagram showing the configuration of a management system of a sixth example of the fourth embodiment. The management system 160 has a configuration similar to that of the second example. In baccarat, as described above, a plurality of play positions are provided on the gaming table 4004, and a bet area 422 is provided for each play position at a position corresponding to each play position on the gaming table 4004. In principle, one player plays at one play position.

[0368] However, when all play positions are filled, a player (back bet player) may appear behind a player (sitting player) playing at a play position and place a bet in the betting area 422 assigned to that sitting player, and such a bet may be permitted depending on the casino or the gaming table 4004. A back bet results in multiple gaming tokens 283 with different user IDs being bet in the same betting area. The management system 160 of this example makes it possible to trace the holder of the gaming token 283 even in such a case.

[0369] In the management system 160 of this example, as in the second example, the user ID of the gaming token 283 is stored in a rewritable area of ​​the RFID tag of the gaming token 283, and no database is used. However, the management system 160 has a player identification system for identifying a player.

[0370] 38, a bet chip 831a of a user ID "P1" and a bet chip 831b of a user ID "P2" are bet in the same bet area 422b. At this time, "P1" and "P2" are read from the bet area 422b as the user IDs of the gaming token 283.

[0371] 39 to 41 are diagrams for explaining examples of payouts when both players win the game. First, as shown in FIG. 38, a payout is made to the player 282a with the user ID "P1". At this time, the management system 160 cannot distinguish whether a payout is made to the player 282a with the user ID "P1" or to the player 282b with the user ID "P2", and cannot make the written information different for a plurality of game tokens 283 in one betting area 422. Therefore, the management control device 256 controls the RF control device 254 to rewrite the user IDs of all game tokens 283 in the betting area 422b to selective information "P1 or P2".

[0372] When the player 282a who has received the payout takes his / her bet chips 831a and payout chips 832a from the bet area 422b, as shown in FIG. 40, bet chips 831b with a user ID of "P1 or P2" remain in the bet area 422b. The dealer confirms that the player 282a has taken the gaming tokens 283, and pays out payout chips 832b with a user ID of "D" to the bet chips 831b, as shown in FIG. 41. At this time, the management control device 256 controls the RF control device 254 to rewrite the user IDs of all the gaming tokens 283 in the bet area 422 to "P1 or P2".

[0373] As a result, both the players 282a and 282b who have placed bets in the same betting area 422 will own the gaming token 283 in which "P1 or P2" is recorded as the user ID.

[0374] If these players 282a and 282b were to bet again in the same betting area 422 using those gaming tokens 283, then "P1 or P2" would be recorded as the user ID on both of the betting chips 831a and 831b. Alternatively, some of the betting chips may contain gaming tokens 283 with user IDs of "P1" or "P2". In these cases, when making a payout in accordance with the game results, the management control device 256 controls the RF control device 254 to record "P1 or P2" as the user ID of all of the gaming tokens 283 placed in the betting area 422 at the time of payout. Selectively write "P2".

[0375] When the bet chip 831 with the user ID "P1 or P2" is collected in the chip tray 212, "D" representing the casino or dealer is written as the user ID.

[0376] Thereafter, when the player 282a, 282b individually bets in the betting area 422 a gaming token 283 on which the user IDs of multiple users are selectively recorded, and the user ID of the player identified by the player identification system matches any of the user IDs of the options, the management control device 256 controls the RF control device 254 to rewrite the selective user ID of the gaming token 283 to the matching user ID.

[0377] For example, when the player 282a bets the gaming token 283 having the user ID “P1 or P2” recorded thereon alone in the betting area 422, the RF control device 254 reads the user ID “P1 or P2” from the betting chip 831 in the betting area 422. The user ID "P2" is read out, and the player identification system recognizes that the user ID of the player who placed the bet in the bet area 422 is "P1." In this case, since the user ID "P1" matches, the management control device 256 controls the RF control device 254 to rewrite the user ID of the bet chip 831 in the bet area 422 to "P1."

[0378] On the other hand, when a player who owns a gaming token 283 on which a user ID is selectively recorded places a bet, and a player who has a user ID that is not included in the options bets in the same betting area 422 and receives a payout according to the game result, the user ID of the gaming token 283 is selectively written to include the user ID of the player as an option.

[0379] For example, if a player 282a bets a gaming token 283 having “P1 or P2” recorded as the user ID in the betting area 422, and another player bets a gaming token 283 having “P3” recorded as the user ID in the same betting area 422, when making a payout according to the game result, the management control device 256 controls the RF control device 254 to rewrite the user IDs of all gaming tokens 283 including the payout chips in the betting area 422 to “P1 or P2 or P3”.

[0380] As described above, in this example, by allowing selective recording as a user ID, it is possible to trace the holder even when multiple players bet in the same betting area. Furthermore, by using a player identification system, it is also possible to definitively rewrite the user ID that was selectively recorded.

[0381] In addition, if multiple players bet on the same bet area 422 and some players win and some players lose, the bet chips of the losing players are collected first, so for the collected bet chips, when they are read by the chip tray 212, "D" is recorded as the user ID, and the above processing is performed for the bet chips that receive the payout chips 832 and the payout chips that are paid out in response to them.

[0382] (Example 7) 42 is a diagram showing the configuration of a management system in a seventh example of the fourth embodiment. The management system 170 has a similar configuration to the management system 130 in the third example. In the management system 170, even when a plurality of players bet in the same betting area 422, it is possible to trace the holder of the gaming token 283.

[0383] 43 to 47 are diagrams for explaining an example of updating the database 57. When the player 282a bets the bet chip 831a in the bet area 422b and the player 282b bets the bet chip 831b in the same bet area 422b, as shown in FIG. 43, the RF control device 254 reads out the chip IDs "C00001" to "C00005" of the bet chip 831a and the chip IDs "C10001" to "C10005" of the bet chip 831b from the bet area 422b as user IDs, and outputs them to the management control device 256 as a combination with the area ID "Area 2" of the bet area 422. Also, the chip IDs "C20001" to "C20100" are read out from the chip tray 212, and the management control device 256 obtains a combination with the area ID "Area T" of the chip tray 212.

[0384] As shown in FIG. 43, at this point in time, in database 57, chip IDs "C00001" to "C00005" are associated with user ID "P1," chip IDs "C10001" to "C10005" are associated with user ID "P2," and chip IDs "C20001" to "C20100" are associated with user ID "D."

[0385] As a result of the game, if both the players 282a and 282b win, the dealer first pays out to either the bet chip 831a or the bet chip 831b, as shown in Fig. 44. At this time, the chip IDs "C00001" to "C00005" of the bet chip 831a and the chip IDs "C10001" to "C10005" of the bet chip 831b are read from the bet area 422b, as well as the chip IDs "C20001" to "C20005" of the payout chip 832a, and are output to the management control device 256 as a combination with the area ID "Area 2" of the bet area 422.

[0386] At this stage, the management control device 256 cannot yet determine whether the payout chip 832a has been paid out to the bet chip 831a with chip IDs "C00001" to "C00005" or to the bet chip 831b with chip IDs "C10001" to "C10005", and therefore does not update the database 57.

[0387] Next, when the player 282a removes the bet chips 831a and the corresponding payout chips 832a from the bet area 422b, only the chip IDs "C10001" to "C10005" of the remaining bet chips 831b are read from the bet area 422b, as shown in FIG. Based on this change, the management control device 256 determines that the payout chips 832a with chip IDs "C20001" to "C20005" read in the bet area 422b have been paid out for the bet chips 831a with chip IDs "C00001" to "C00005", and rewrites the user ID associated with the chip IDs "C20001" to "C20005" in the database 57 from "D" to "P1", i.e., the user ID associated with the bet chips 831a removed from the bet area 422b along with the payout chips 832a with chip IDs "C20001" to "C20005".

[0388] The dealer confirms that the bet chip 831a and the payout chip 832a paid out in response to it are removed from the bet area 422b, and pays out the payout chip 832b in response to the bet chip 831b to the same bet area 422b as shown in Fig. 46. Then, the chip IDs "C10001" to "C10005" of the bet chips 831b and the chip IDs "C20006" to "C20010" of the payout chips 832b are read from the bet area 422b, and are recorded in the management control device 256 in combination with the area ID "Area 2" of the bet area 422.

[0389] Thereafter, when the player 282b takes the bet chip 831b and the payout chip 832b, as shown in Fig. 47, the chip ID is not read from the bet area 422b, and only the chip ID read from the chip tray 212 is input to the management control device 256. Based on this change, the management control device 256 determines that the payout chips 832b with chip IDs "C20006" to "C20010" have been passed to the same player as the player with chip IDs "C10001" to "C10005", and updates the database 57 so that the user IDs associated with the chip IDs "C20006" to "C20010" in the database 57 become the same as the user IDs associated with the chip IDs "C10001" to "C10005".

[0390] As described above, the management system 170 of this example detects that the bet chip 831 and the payout chip 832 have been removed from the betting area together, and updates the database 57 so that the user ID of the payout chip 832 becomes the same as the user ID of the betting chip 831. Therefore, even if game tokens 283 of multiple players have been bet on the same betting area 422, it is possible to know to which player the payout chip 832 has been paid out by paying out the game tokens to those players in order, and update the database 57, thereby making it possible to trace the holder of the game token.

[0391] (Example 8) 48 is a diagram showing the configuration of a management system of an eighth example of the fourth embodiment. The management system 180 has a similar configuration to the management system 140 of the fourth example. However, in the management system 180, a player pair area 444, a tie area 445, and a banker pair area 446 are provided as betting areas on a gaming table 4004. Also, antennas 517, 518, and 519 are provided on the gaming table 4004 in correspondence with the player pair area 444, the tie area 445, and the banker pair area 446.

[0392] Each of these areas 444 to 446 is divided into sections for playing positions within that area, and when a player bets on these areas 444 to 446, the player places a betting chip in the position (section) within these areas that corresponds to the player's playing position.

[0393] That is, the player pair area 444, the tie area 445, and the bank pair area 446 are shared betting areas shared by multiple players. In the example of FIG. 48, players 282a to 282c are participating in the game, and among them, players 282b and 282c bet bet chips 831b and 831c on the tie area 445, respectively.

[0394] In this example, for the common betting areas 444 to 446, the holder of the gaming token 283 can be traced in the same manner as in the sixth or seventh example. Even if the management system 180 does not have the database 57, the holder of the gaming token 283 can be traced in the same manner as in the sixth example, and even if the management system 180 does not have a player identification system, the holder of the gaming token 283 can be traced in the same manner as in the seventh example for the common betting areas.

[0395] (Example 9) FIG. 49 is a diagram showing the configuration of a management system in a ninth example of the fourth embodiment. The management system 190 includes a player identification system. In this example, the gaming token 283 is traced without using the database 57. The gaming table 4004 is provided with pay areas 424a-424e and corresponding antennas 516a-516e. The fixed information of the RFID tag of the gaming token 283 stores information indicating the amount (value) of the gaming token 283, and the variable information stores the user ID of the holder.

[0396] In this example, the database 57 may also be used, in which case a chip ID is stored in the gaming token 283, and the amount (value) of the gaming token 283 and the user ID of the holder are stored in the database 57 in association with the chip ID.

[0397] As shown in FIG. 50, when the bet chips 831a (five chips of the value "100") of the player 282a and the bet chips 831b (two chips of the value "1000") of the player 282b are placed in the bet area 422b, five gaming tokens 283 with an amount of "100" and a user ID of "P1" are read from the bet area 422b, and two gaming tokens 283 with an amount of "1000" and a user ID of "P2" are read, and these are output to the management control device 256 together with the area ID of the bet area 422, which is "Area 2."

[0398] The management control device 256 detects the bet amount for each player by calculating the total value of the bet chips for each player for each bet area 422. In the case of FIG. 50, the management control device 256 detects that the bet amount for user ID "P1" is "500" and the bet amount for user ID "P2" is "2000".

[0399] As a result of the game, if both the players 282a and 282b win, the dealer pays out (redeems) the bet chips 831a and 831b in turn. As shown in FIG. 51, when paying out the payout chip 832a for the bet chip 831a, the dealer places the payout chip 832a in the pay area 424b.

[0400] At this time, the RF control device 254 reads the gaming tokens 283 in the pay area 424b, reads that there are five gaming tokens 283 of the amount "100", and outputs this to the management control device 256. The management control device 256 detects the payout amount by calculating the total amount of the payout chips 832a read in the pay area 424b.

[0401] The management control device 256 compares the payout amount of the payout chip 832a with the bet amount for each player in the bet area 422b, and identifies the player whose bet amount matches the payout amount. In the case of FIG. 51, five payout chips 832a with an amount of "100" are read from the pay area 424b, and the payout amount is detected to be "500". The management control device 256 determines that the payout amount "500" matches the bet amount "500" of the bet chip 831a of the user ID "P1", and rewrites the user ID of the payout chip 832a to "P1".

[0402] After that, when the player 282a takes the payout chip 832a and the bet chip 831a, the bet chip 831b of the player 282b remains in the bet area 422b as shown in Fig. 52. When the dealer places the payout chip 832b to be paid out for the bet chip 831b in the pay area 424b, the management control device 256 detects the payout amount of the payout chip 832b by calculating the total amount of the payout chip 832b.

[0403] The management control device 256 compares the payout amount of the payout chip 832b with the bet amount for each player in the bet area 422b, and identifies a player whose bet amount matches the payout amount. In the case of FIG. 52, two payout chips 832b with an amount of "1000" are read from the pay area 424b, and the payout amount is detected to be "2000". The management control device 256 determines that the payout amount "2000" matches the bet amount "2000" of the bet chip 831b of the user ID "P2", and rewrites the user ID of the payout chip 832b to "P2".

[0404] As described above, in the management system 190 of this example, even if multiple players bet in the same bet area 422, if their bet amounts are different, it is determined to which player the payout chip is to be paid out based on the bet amount and the payout amount of the payout chip.

[0405] (Example 10) In the above first to ninth examples, if the player 282 is a non-member who is not registered as a member, the player identification system cannot identify the player 282 because a user ID is not given to such a non-member. Also, as described above, for the gaming token 283 owned by a non-member, a valid user ID cannot be stored in the RFID tag or database 57, so "Unknown" is recorded as the user ID.

[0406] When the management system pays out a payout chip 832 to a non-member player, it sets the user ID of the payout chip 832 to "Unknown," and when it collects a bet chip 831 from the non-member player, it sets the user ID of the bet chip 831 to "D."

[0407] When a member player and a non-member player bet in the same betting area 422, if both players win the game, the dealer may make a payout under the rule that the dealer always makes a payout to the non-member player, or always makes a payout to the member player.

[0408] For example, if a rule is in place that non-members are always paid out first, the management system will rewrite the user ID of the first paid out payout chip 832 to "Unknown", and rewrite the user ID of any subsequently paid out payout chip 832 to the user ID of a player who is a member, using the example above.

[0409] Also, for example, if a rule is applied that the member is always paid out first, the management system rewrites the user ID of the first paid out payout chip 832 to the user ID identified from the bet chip 831, and rewrites the user ID of the later paid out payout chip 832 to "Unknown."

[0410] When identifying a player using a card authentication system, the dealer scans the member's card 281 himself, and can therefore know which player is a member, but when identifying a player using a face recognition system, the dealer cannot know which player is a member. Therefore, visual information indicating the play position or betting area where the user ID was recognized may be shown to the dealer on a monitor or the like as the recognition result by the face recognition system.

[0411] (Example 11) 53 is a diagram showing an example of a bet area in the eleventh example of the fourth embodiment. In this example, the bet area 422 of each play position is divided into a bet area 411 for members and a bet area 412 for non-members, and the antenna is also divided into an antenna 5111 for members and an antenna 5112 for non-members.

[0412] The management control device 256 controls the RF control device 254 to rewrite the user ID of the gaming token 283 for the bet chips 831 bet in the bet area 411 for members, as in the first to ninth examples above, and rewrites all user IDs of the payout chips 832 paid out in response to the bet chips 831 bet in the bet area 412 for non-members to "Unknown".

[0413] According to this example, a gaming token 283 in which a user ID given to a player is stored in itself or in the database 57 and a gaming token 283 in which a user ID given to a player is not stored in itself or in the database 57 (the user ID is "Unknown") are not read in a mixed manner, and it is possible to effectively trace a gaming token 283 in which a user ID given to a player is stored in itself or in the database 57.

[0414] In this example, instead of the antennas 5111 and 5112, one antenna may be provided across the betting area 411 for members and the betting area 412 for non-members. In this case, when gaming tokens 283 are bet in the betting area 411 for members and the betting area 412 for non-members, respectively, the dealer can recognize which betting chips 831 belong to members and which betting chips 831 belong to non-members.

[0415] When making a payout to any of the bet chips 831, the dealer may make the payout under an operation rule that the payout chips 831 of the members are paid out first. In this way, the management system can determine that the payout chips 832 paid out first are those paid out to the members. The dealer may also make a payout according to an operation rule that the payout chips 831 of the non-members are paid out first. In this case, the management system can determine that the payout chips 832 paid out first are those paid out to the non-members.

[0416] Figures 54A and 54B are diagrams showing other examples of bet areas in the eleventh example of the fourth embodiment. In this example, the bet area 422 of each play position is selectively set to a bet area 422 for members as shown in Figure 54A, or a bet area 422 for non-members as shown in Figure 54B.

[0417] A display unit 413 is provided near each betting area 422 to variably display whether the betting area 422 is set for a member or a non-member. This display unit 413 is installed under the lining of the gaming table 4004, and the display information is visible to the player through the lining.

[0418] The means for visually indicating whether each betting area 422 is set for a member or a non-member is not limited to the display unit 413 embedded under the lash of the gaming table 4004. For example, whether each betting area 422 is set for a member or a non-member may be displayed by a monitor installed on the gaming table 4004 so as to be visible to the player.

[0419] By controlling the RF control device 254, if the bet area 422 is set for a member, the management control device 256 rewrites the user ID of the gaming token 283 for the bet chips 831 bet there, as in the first to ninth examples above, and if the bet area 422 is set for a non-member, the management control device 256 rewrites all of the user IDs of the payout chips 832 paid out in response to the bet chips 831 bet there to "Unknown".

[0420] Even in this example, a gaming token 283 in which a user ID given to a player is stored in itself or in the database 57 and a gaming token 283 in which a user ID given to a player is not stored in itself or in the database 57 (the user ID is "Unknown") are not read in a mixed manner, and it is possible to effectively trace a gaming token 283 in which a user ID given to a player is stored in itself or in the database 57.

[0421] (Example 12) In the above first to ninth examples, even when the gaming tokens 283 are exchanged between the dealer and the player at the gaming table 4004, it is possible to trace the holder of the gaming token 283. In this case, the management system includes a progress status determination means for determining the progress status of the game (i.e., whether a bet is being made, a game is being played, or settlement is being made). As such progress status determination means, the card distribution device 4003 can be used, but any other means may also be used.

[0422] In the management system of this example, the management control device 256 controls the RF control device 254 during betting to make each antenna periodically read at a predetermined time interval. The management control device 256 determines that the gaming token 283 is being exchanged when a gaming token 283 with a user ID of "D" is read in any of the betting areas 422 or any of the pay areas 424 (hereinafter referred to as "reading areas of the gaming table 4004") during betting, and when a gaming token 283 with a user ID of the user ID assigned to a member is read in the chip tray 212.

[0423] This is because, in terms of the operation of Baccarat, during betting, the gaming token 283 cannot be moved from the chip tray 212 onto the gaming table 4004 except for money exchange, and the gaming token 283 of a player on the gaming table 4004 cannot be moved to the chip tray 212. Note that when the game progress status is "in game", such movement of the gaming token 283 is considered as a fraudulent act, and therefore the management control device 256 may output an alarm when it detects such movement of the gaming token 283 during the game.

[0424] When a gaming token 283 whose user ID is the user ID assigned to a member or "Unknown" is read by the chip tray 212 during betting, the management control device 256 determines that the gaming token 283 is a gaming token 283 (pre-exchange chips) that has been placed by a player on the gaming table 4004 for exchange between chips.

[0425] Specifically, if a user ID is stored in the gaming token 283 itself, the management control device 256 determines that an exchange has occurred when the user ID given to the member or "Unknown" is read from the chip tray 212 during a bet, and if a user ID is stored in the database 57, the management control device 256 determines that an exchange has occurred when the number of gaming tokens 283 read from the chip tray 212 during a bet decreases. Alternatively, if a user ID is stored in the database 57, the management control device 256 may determine that an exchange has occurred when the number of gaming tokens 283 read from the chip tray during a bet increases.

[0426] In addition, when a gaming token 283 with a user ID of "D", indicating that the gaming token is held by a casino or a dealer, is read in the reading area of ​​the gaming table 4004 during a bet, the management control device 256 determines that the gaming token 283 is a gaming token 283 (exchanged chip) to be given to the player in correspondence with the pre-exchange chip.

[0427] Specifically, if a user ID is stored in the gaming token 283 itself, the management control device 256 determines that an exchange has been made when the user ID "D" is read from the reading area of ​​the gaming table 4004 during betting, and if a user ID is stored in the database 57, the management control device 256 periodically reads the reading area of ​​the gaming table 4004 during betting and determines that the gaming token 283 with the user ID "D" has been read from the reading area of ​​the gaming table 4004 by referring to the database 57 each time it is read.

[0428] The management control device 256 rewrites the user ID of the pre-exchanged chip to "D", which represents a casino or a dealer, and rewrites the user ID of the exchanged chip to the user ID of the pre-exchanged chip. Specifically, if the user ID is stored in the RFID tag of the gaming token 283, the management control device 256 controls the RF control device 254 to rewrite the user ID stored in the corresponding pre-exchanged chip and exchanged chip, and if the user ID is stored in the database 57 in association with the chip ID, the management control device 256 rewrites the user ID associated with the corresponding chip ID in the database 57.

[0429] In addition, after identifying the pre-exchange chip and the exchanged chip, the management control device 256 may control the RF control device 254 to exchange their user IDs (if the user ID is stored in the gaming token 283) or update the database 57 (if the user ID is stored in the database 57).

[0430] In the above embodiment, the member's card 281 is a magnetic card, and the card reader 253 is a magnetic card reader that reads information from the magnetic stripe of the member's card 281. Alternatively, an RFID tag may be embedded in the member's card 281, and the user ID may be recorded in the RFID tag. In this case, an RFID reader consisting of an antenna and an RF control device 254 is used as the card reader 253. Also, such an antenna may be provided at each play position. In this case, the player has his / her member's card 281 read at each play position without handing it over to the dealer. The user ID read from the member's card 281 is transmitted from each antenna to the RF control device 254 together with information identifying the play position. Furthermore, the antenna 515 and the RF control device 254 provided in the betting area 422 may be an RFID reader for reading the member's card 281. In this case, the player can have the antenna 515 read the user ID by placing the member's card 281 in the betting area 422 at his / her playing position.

[0431] Various embodiments of the present invention have been described above. However, it goes without saying that the above-mentioned embodiments can be modified by those skilled in the art within the scope of the present invention, and the device of the present embodiments may be appropriately modified according to the needs of the game to which it is applied.
