MODE FOR CARRYING OUT THE INVENTION

[0027] (First Embodiment) In a casino or other gaming venue, game substitute currency is stacked up and placed on the game table. However, there is a problem that the total amount cannot be accurately read by the IC tag reader provided under the game table. If the sensitivity of the reader is increased, the game substitute currency placed at different positions (where the outcome depends on the position) will be added up, and the total amount of game substitute currency at each position cannot be grasped. Also, in imaging from a camera, there are problems such as blind spots due to the viewing angle of the camera or the total amount of game substitute currency cannot be grasped because it is in the shadow due to overlapping.

[0028] Also, in the baccarat game, which is often played, the card may be bent due to the player's card squeeze (the act of bending a face-down card and gradually looking at the rank of the card while enjoying it), etc., and there is a problem that the rank and suit of the card cannot be determined by image analysis from the camera.

[0029] In addition, it has been recognized that cheating in the gaming table has become more sophisticated, and new problems have emerged, such as the fact that sophisticated cheating methods that cannot be detected by simply detecting a large amount of winnings at the gaming table, or cheating by means of camera monitoring or tracking of winnings, cannot be detected. In addition, the prior art is not sufficient to prevent fraudulent acts resulting from collusion between dealers and players.

[0030] In order to solve the above various problems, a fraud detection system in a casino having a plurality of gaming tables according to the first embodiment is a fraud detection system in a casino having a plurality of gaming tables, comprising: a game recording device that records, as video via a camera, the progress state of a game played on the gaming table, including the dealer and the players; an image analysis device that analyzes the video of the recorded progress state of the game; a card distribution device that determines and displays the win / loss result of each game on the gaming table; and a control device that detects fraudulent acts performed on the gaming table using the image analysis result by the image analysis device and the win / loss result determined by the card distribution device.

[0031] Furthermore, in the fraud detection system, the card distribution device has a structure capable of reading the rank of the cards to be distributed, and the control device has a structure capable of collating the rank information of the cards obtained by the image analysis device from the video of each card distributed on the gaming table with the rank information of the cards read by the card distribution device to determine whether they match or not.

[0032] Furthermore, in the fraud detection system, the image analysis device or the control device has an artificial intelligence-utilizing or deep learning structure capable of obtaining the rank information of the cards from the cards distributed on the gaming table and bent or soiled by the players.

[0033] Furthermore, there is a fraud detection system in which the control device grasps the position, type, and number of gaming tokens wagered by each player via the image analysis device, and determines whether the collection of losing gaming tokens wagered by each player and the payment to winning gaming tokens are appropriately made according to the winning or losing results of the game by analyzing the video of the game progress state via the image analysis device.

[0034] Furthermore, there is a fraud detection system in which the image analysis device or the control device has an artificial intelligence utilization type or deep learning structure capable of obtaining information on the type, number, and position of the wagered gaming tokens even when some or the entire one of the plurality of gaming tokens placed on the gaming table is hidden due to the blind spot of the camera.

[0035] Furthermore, there is a fraud detection system in which the control device has an artificial intelligence utilization type or deep learning structure capable of comparing and calculating whether the amount of the grasped gaming tokens in the dealer's gaming token tray on the gaming table has increased or decreased according to the collection of losing gaming tokens wagered by each player and the payment amount to winning gaming tokens after the game ends and is settled according to the winning or losing results of the game.

[0036] Furthermore, there is a fraud detection system in which the control device has an artificial intelligence utilization type or deep learning structure capable of grasping the position and amount of the wagered gaming tokens at each play position on the gaming table, and extracting the winning or losing history of each player and the amount of the obtained gaming tokens from the winning or losing results of each game as a special situation by comparing with the statistical data of past games.

[0037] Furthermore, there is a fraud detection system in which the control device has an artificial intelligence utilization type or deep learning structure capable of extracting, as a special situation compared with the statistical data of past games, a state in which the amount of the wagered gaming tokens at a play position on a certain gaming table is less when losing than when winning.

[0038] Furthermore, there is a fraud detection system in which the control device can identify an individual player who is extracted as the specific situation via the image analysis device or has won a certain amount or more at the play position.

[0039] Furthermore, there is a fraud detection system in which the control device has a warning function that notifies the presence of the specific player at another gaming table when the specific player leaves his seat and arrives at another gaming table.

[0040] In order to solve the above various problems, the fraud detection system in a casino having a plurality of gaming tables according to the present invention includes a game recording device that records, as an image via a camera, the progress state of the game being played on the gaming table, including the dealer and the players; a card distribution device that determines and displays the winning or losing results of each game on the gaming table; an image analysis device that analyzes the image of the recorded progress state of the game; and a control device that can detect bills and gaming tokens on the gaming table using the image analysis result by the image analysis device. The image analysis device or the control device can detect that an exchange between bills and gaming tokens is being made on the gaming table in a situation other than during card dealing, based on information obtained from the card distribution device or the dealer. Further, it can recognize the total amount of genuine bills verified by a black light. Moreover, even when a plurality of gaming tokens placed on the gaming table as exchange targets are partially or entirely hidden due to a blind spot of the camera, it can recognize the total amount of the gaming tokens, and compare the total amount of the bills given out by the players on the gaming table with the total amount of the gaming tokens given out by the dealer, and can determine whether or not the amounts of both are the same. It has an artificial intelligence utilization type or deep learning structure.

[0041] Furthermore, there is a fraud detection system in which the control device can compare and calculate whether the amount of gaming substitute currency grasped in the dealer's gaming substitute currency tray on the gaming table has increased or decreased according to the payment amount of the gaming substitute currency corresponding to the exchanged bills after the exchange between bills and gaming substitute currency has been made and settled. It has an artificial intelligence utilization type or a deep learning structure.

[0042] Furthermore, there is a fraud detection system in which the control device can compare and calculate the match or mismatch between the deposit amount of the bills by the dealer's input and the total amount of the bills by the image analysis result by the image analysis device after the exchange between bills and gaming substitute currency has been made and settled. It has an artificial intelligence utilization type or a deep learning structure. Moreover, further, the control device can compare and calculate the match or mismatch between the total deposit amount of the bills by the dealer's input on the gaming table handled by the dealer and the total amount of the bills by the image analysis result by the image analysis device. It has an artificial intelligence utilization type or a deep learning structure.

[0043] According to the fraud detection system of the present embodiment, even if the card is bent due to the player squeezing the card, which is often done in baccarat games and the like, the rank and suit of the card can be determined by image analysis, and the total amount of the dead corners and overlapping gaming substitute currency can be grasped together with the position. Also, fraud during the exchange of bills and gaming substitute currency can be detected.

[0044] The overall outline of the fraud detection system in a casino having a plurality of gaming tables according to the first embodiment of the present invention will be described in more detail below. FIG. 1 is a diagram showing the overall outline of the system. The fraud detection system in a casino having a plurality of gaming tables 4 includes a game recording device 11 that records the progress state of the game played on the gaming table 4 as video via a plurality of camera devices 2 including a player 6 and a dealer 5, and an image analysis device 12 that analyzes the image of the recorded progress state of the game. Further, it includes a card distribution device 3 that determines and displays the win / loss result of each game on the gaming table 4. The card distribution device 3 is a so-called electronic shoe already used by those skilled in the art, in which the rules of the game are programmed in advance, and it can read the information of the distributed card C and determine the win / loss of the game. For example, in the baccarat game, the win of the banker, the win of the player, and a tie (draw) are basically determined by the ranks of 2-3 cards, and the determination result (win / loss result) is displayed on the result display lamp 13.

[0045] This fraud detection system further includes a control device 14 that compares the actual rank of the card obtained from the image analysis result by the image analysis device 12 with the win / loss result determined by the card distribution device 3, and detects fraud (such as a mismatch between the total rank of the distributed cards and the win / loss result) occurring on the gaming table 4. The card distribution device 3 has a structure capable of reading the rank (A, 2-10, J, Q, K) and suit (hearts, spades, etc.) of the card C manually distributed by the dealer 5. The control device 14 collates the rank and suit information obtained by the image analysis device 12 (using artificial intelligence) from the video of each card distributed on the gaming table 4 (captured using the camera device 2) with the rank and suit information of the card read by the card distribution device 3 to determine whether they match or not. The image analysis device 12 and the control device 14 in this fraud detection system have a structure that comprehensively includes a computer, a program, and a memory composed of an integrated or multiple configurations.

[0046] The image analysis device 12 and the control device 14 have an artificial intelligence utilization type or a deep learning structure capable of obtaining information on the rank of a card even if the card C is distributed on the gaming table 4 and is bent or soiled by the player 6. As shown in FIG. 3, for a soiled card C, a situation where it is difficult to distinguish between clubs and spades may occur. Even in such a case, by analyzing and determining the image using an artificial intelligence utilization type computer or control system, or deep learning (structure) technology, it becomes possible to distinguish the suit. Also, even if the card is bent due to card squeezing by the player, which is often done in baccarat games and the like, by using self-learning of a large number of image deformation examples, etc., an artificial intelligence utilization type computer or control system, or deep learning (structure) technology can recognize the suit and rank that the card had before deformation. Since an artificial intelligence utilization type computer or control system, or deep learning (structure) technology is already known and available to those skilled in the art, detailed description thereof will be omitted.

[0047] The control device 14 having an artificial intelligence utilization type or a deep learning structure can grasp at which position (player, banker, or pair) in the bet area 8 each player 6 bets the gaming substitute currency 120 via the camera device 2 and the image analysis device 12, the type of the bet gaming substitute currency 120 (the gaming substitute currency 120 has different value amounts assigned to each color), and the number of pieces. The gaming substitute currency 120 may not only be stacked in alignment in the vertical direction but also may overlap with a shift as shown in FIG. 2A. In this case, when the camera device 2 is located in the direction of arrow X shown in FIG. 2A (or when the direction of the gaming substitute currency 120 becomes a blind spot relatively), it is assumed that the gaming substitute currency 120 cannot be seen (enters the blind spot) as shown in FIG. 2B. In the artificial intelligence utilization type computer or control system and deep learning (structure) technology, using a self-learning function or the like, the hiding due to the blind spot of the gaming substitute currency 120 (when a part of a single gaming substitute currency is hidden or when the entire gaming substitute currency is hidden) is recognized, and the number of pieces and the like are accurately grasped. Thus, since it is possible to grasp at which position (player, banker, or pair) in the bet area 8 the gaming substitute currency 120 is bet, the type of the bet gaming substitute currency 120 (the gaming substitute currency 120 has different value amounts assigned to each color), and the number of pieces, according to the win / loss result of the game determined by the card distribution device 3 in each game, the control device 14 determines whether the collection of the losing gaming substitute currency bet by each player 6 (shown by arrow L) and the payment to the winning player 6W of the winning gaming substitute currency (120W) are properly performed according to the win / loss result of the game by analyzing the video of the game progress state via the image analysis device 12. When the determination result analyzed by the intelligent control device 14 via the image analysis device 12 is different from the reading result by other means (for example, the reading result by RFID), the analyzed image can be saved and verified later. As a result of the verification, if it is an error of the intelligent control device 14, the analyzed image can be used as sample data for supervised learning in deep learning technology and used to improve the accuracy of the intelligent control device 14.

[0048] The control device 14 can analyze and grasp the total amount of the game substitute currency 120 in the game substitute currency tray 17 of the dealer 5 on the gaming table 4 using the image analysis device 12. After the game ends and is settled, according to the recovery of the losing game substitute currency 120 wagered by each player 6 and the amount of payment 120W of the winning game substitute currency to the winning player 6W, it is possible to compare and calculate whether the total amount of the game substitute currency 120 in the game substitute currency tray 17 has increased or decreased according to the winning or losing result of the game. Even if the total amount of the game substitute currency 120 in the game substitute currency tray 17 is always grasped by means such as RFID, whether the increase or decrease amount is correct or not is determined by the control device 14 analyzing the video of the progress of the game through the image analysis device 12. These also utilize an artificial intelligence utilization type or a deep learning structure.

[0049] In this example, based on the winning or losing result of the game, information on which type of game substitute currency 120 was wagered, how many were wagered, and at which position (player, banker, pair) in the bet area 8, and the increase or decrease amount of the game substitute currency 120 in the game substitute currency tray 17 after the recovery of the losing game substitute currency and the repayment for the winning game substitute currency 120, fraud and mistakes are detected. Therefore, even without knowing the movement of the game substitute currency 120 after the game ends, that is, whether the wagered game substitute currency 120 has moved to the player side or the dealer side, fraud and mistakes can be detected.

[0050] Here, for example, in the case of baccarat, the winning or losing result of the game can be determined according to the baccarat rules by reading the rank of the cards C dealt in that game in the card dealing device 3. Also, the winning or losing result of the game can be determined by photographing the gaming table 4 with the camera device 2, analyzing the image with the image analysis device 12, and comparing the analysis result with the game rules by the control device 14. In this case, the winning or losing result determination device is constituted by the camera device 2, the image analysis device 12, and the control device 14. Information on which player at each play position 7 and how many and which type of gaming substitute currency 120 is bet at which position (player, banker, pair) in the bet area 8 can be obtained by photographing the gaming substitute currency 120 placed in the bet area 8 with the camera device 2 and analyzing the image for each play position 7 with the image analysis device 12.

[0051] Also, the increase or decrease amount of the gaming substitute currency 120 in the gaming substitute currency tray 17 before and after the collection of the losing gaming substitute currency 120 and the repayment for the winning gaming substitute currency 120 can be calculated by comparing the total amount of the gaming substitute currency 120 in the gaming substitute currency tray 17 before the collection of the losing gaming substitute currency 120 and the repayment for the winning gaming substitute currency 120 with the total amount of the gaming substitute currency 120 in the gaming substitute currency tray 17 after the collection of the losing gaming substitute currency 120 and the repayment for the winning gaming substitute currency 120. The total amount of the gaming substitute currency 120 in the gaming substitute currency tray 17 before the collection of the losing gaming substitute currency 120 and the repayment for the winning gaming substitute currency 120, and the total amount of the gaming substitute currency 120 in the gaming substitute currency tray 17 after the collection of the losing gaming substitute currency 120 and the repayment for the winning gaming substitute currency 120 can be detected by photographing the gaming substitute currency tray 17 containing the gaming substitute currency 120 with the camera device 2 and analyzing the image with the image analysis device 12. Also, by embedding an RFID indicating the amount in the gaming substitute currency 120 and providing an RFID reader in the gaming substitute currency tray 17, the total amount of the gaming substitute currency 120 accommodated in the gaming substitute currency tray 17 may be detected.

[0052] For example, before the start of the game, the total amount of the substitute gaming currency 120 in the substitute gaming currency tray 17 is Bb, and after the game ends and the collection of the losing substitute gaming currency and the repayment for the winning substitute gaming currency are completed, the total amount of the substitute gaming currency 120 in the substitute gaming currency tray 17 is Ba. Also, in this game, assume that the total amount of all play positions 7 of the substitute gaming currency 120 bet in the player area is bp, the total amount of all play positions 7 of the substitute gaming currency 120 bet in the banker area is bb, and the total amount of all play positions 7 of the substitute gaming currency 120 bet in the tie area is bt. For example, when the winning or losing result of this game is the banker's win, Ba - Bb = bp - bb + bt should hold. Alternatively, the total amount Ba of the substitute gaming currency 120 in the substitute gaming currency tray 17 after the game ends should be (Bb + bp - bb + bt). If it is not the case, it can be determined that there is an irregularity or a mistake in the collection or repayment of the substitute gaming currency.

[0053] FIG. 13A is a diagram showing details of the substitute gaming currency tray of the present embodiment, and FIG. 13B is a diagram showing another example of the substitute gaming currency tray. The substitute gaming currency tray 17 is provided with a recovered substitute gaming currency tray 171 for collecting and temporarily storing the substitute gaming currency 120L bet by the losing player 6L and a repayment substitute gaming currency tray 172 for storing the substitute gaming currency 120W to be repaid. The image analysis device 12 and the control device 14 grasp the position, type, and number of the substitute gaming currency 120L bet by the losing player 6L, and calculate the increased amount of the substitute gaming currency 0L in the game (the amount of the substitute gaming currency 120 that should be in the recovered substitute gaming currency tray 171). Further, the image analysis device 12 and the control device 14 grasp the actual total amount of the substitute gaming currency 120 in the recovered substitute gaming currency tray 171, and compare the should-be total amount with the actual total amount to determine whether there is a difference.

[0054] In addition, for the repayment of the 120 game substitute coins 120W to the winning player 6W, by using 120 game substitute coins in the repayment game substitute coin tray 172, sufficient time can be ensured to grasp the actual total amount of the 120 game substitute coins in the collected game substitute coin tray 171 after the image analysis device 12 and the control device 14 have collected them.

[0055] As shown in FIG. 1, the gaming table 4 is provided with a disposal area 41 and / or a disposal slot 42 for disposing of the cards C used in the game. Each time the game ends, the cards C used in the game are collected and placed in the disposal area 41 or the disposal slot 42 on the gaming table 4 for disposal.

[0056] The gaming table 4 further includes a marker 43 indicating the win or loss of the game. FIG. 4A is a plan view showing the front of the marker, and FIG. 4B is a plan view showing the back of the marker. In the baccarat game, two types of markers are used: a marker 43a indicating the player's win and a marker 43b indicating the banker's win. When the result of the game is out, the dealer 5 turns over the marker of the winning party among the player or the banker. This clearly shows the win or loss of the game on the table. The turned-over marker is returned to its original state by the dealer 5 after the collection and repayment of the game substitute coins 120. Returning the marker to its original state also means that the next game can be started.

[0057] As described above, in this embodiment, the control device 14 calculates the balance of the game substitute coins based on the amount of the bet game substitute coins on the gaming table 4 and the win or loss result of each game, and verifies the increase in the balance of the game substitute coins in the game substitute coin tray 17 after the game. If a difference is detected in this verification, the control device 14 issues an alarm or adds a record to that effect to the recording of the video taken by the camera device 2. The casino operator can investigate the cause of the difference by checking the video.

[0058] The fraud detection system of this embodiment adds and subtracts the increase or decrease amount of the game substitute currency in the game from the total amount of the game substitute currency 120 in the game substitute currency tray 17 before the settlement of each game, based on the position, type, and number of the game substitute currency 120 wagered by all players 6 in the game and the win / loss result of the game obtained by the win / loss result determination device. Then, it compares the total amount that should be in the game substitute currency tray 17 after settlement at the end of the game with the actual total amount of the game substitute currency 120 in the game substitute currency tray 17 at the end of the game obtained through the image analysis device 12, and determines whether there is a difference between the total amount that should be and the actual total amount.

[0059] The control device 14 grasps the position, type, and number of the game substitute currency wagered by each player through the image analysis device 12. When all the collection of the losing game substitute currency wagered by each player is completed, it grasps the actual total amount of the game substitute currency in the game substitute currency tray, and calculates the total amount that should be in the game substitute currency tray 17 by adding the increase amount of the game substitute currency tray 17 in the game from the position, type, and number of the game substitute currency wagered by the losing player to the total amount of the game substitute currency in the game substitute currency tray before the settlement of each game. Then, it compares the total amount that should be with the actual total amount of the game substitute currency 120 in the game substitute currency tray 17, and determines whether there is a difference between the total amount that should be and the actual total amount.

[0060] The control device 14 compares the total amount of the game substitute currency 120 in the game substitute currency tray 17 before the settlement of each game with the total amount of the game substitute currency 120 that should be in the game substitute currency tray 17 in the game, which is obtained by adding the increase in the game substitute currency tray 17 in the game calculated from the position, type, and number of the game substitute currency 120 wagered by the losing player, and determines that there is no difference between the total amount that should be and the actual total amount. And when comparing the total amount that should be in the game substitute currency tray 17 after the settlement at the end of the game with the actual total amount of the game substitute currency 120 in the game substitute currency tray 17 at the end of the game obtained through the image analysis device 12, if it is determined that there is a difference between the total amount that should be and the actual total amount, it is determined as an error in payment, and a payment error signal for notifying the error in payment is generated.

[0061] The game substitute currency tray 17 is provided with a recovered game substitute currency tray 171 for recovering and temporarily storing the game substitute currency 120 wagered by the losing player. The image analysis device 12 adds the increase in the game substitute currency 120 in the game calculated from the position, type, and number of the game substitute currency 120L wagered by the losing player, and compares the total amount of the game substitute currency 120 that should be in the recovered game substitute currency tray 171 with the actual total amount of the game substitute currency 120 in the recovered game substitute currency tray 171, and determines whether there is a difference between the total amount that should be and the actual total amount.

[0062] When the control device 14 determines that the actual total amount of the game substitute currency 120 grasped in the game substitute currency tray 17 of the dealer 5 on the game table 4 does not correspond to the increase or decrease amount of the game substitute currency calculated from the total amount of the game substitute currency wagered by all players and the winning or losing result of the game, the game recording device 11 adds an index or time to the acquired video, or can identify and play back the recovery scene or payment scene of the game substitute currency 120 so that the record of the game in which the above difference occurred can be analyzed in the game recording device 11.

[0063] In this way, the control device 14 obtains the total amount of gaming substitute currency (chips) in the gaming substitute currency tray 17 after settlement at the end of the game via the image analysis device 12. In this case, the determination after settlement is assumed to be when any one of the following 1) to 4) occurs. 1) When the repayment for the winning gaming substitute currency (winning chips) 120 is completed. 2) When the card C used in the game is collected and discarded in the discard area or discard slot of the table. 3) When a predetermined button attached to the win / loss result determination device is pressed. 4) When the marker 43 indicating the win / loss is reset.

[0064] In the above table game management system, the management control device captures the position, type, and number of gaming substitute currency placed by the game participants in each game. This is assumed to be when any one of the following 1) to 3) is detected. 1) When the card distribution device detects that the first card is drawn. 2) Before and after being drawn. 3) After the management control device recognizes the sign of the dealer's bet end.

[0065] Also, the control device 14 grasps the position (player, banker, or position bet on a pair) and amount (type and number) of the gaming substitute currency bet at each play position 7 of the gaming table 4, and compares the win / loss history of each player 6 and the amount of gaming substitute currency obtained (winning amount) obtained from the win / loss results of each game with the statistical data of a large number (big data) of past games. It has an artificial intelligence utilization type or deep learning structure that can extract it as a special situation (set by the casino). Typically, the occurrence of a winning amount of a certain amount (one million dollars) or more, or at a play position 7 of a certain gaming table 4, where the amount of gaming substitute currency bet when losing is small and the amount of gaming substitute currency bet when winning is large continues for several games, and this can be extracted as a special situation compared with the statistical data (big data, etc.) of past games. It is equipped with a control device 14 having an artificial intelligence utilization type or deep learning structure.

[0066] Furthermore, the control device 14 of this cheating detection system is structured such that (integrated with the image analysis device 12) it is possible to identify an individual player 6 at a play position 7 where a special situation is extracted or a win of a predetermined amount or more is achieved. Such identification of the player 6 is performed in the image analysis device 12 by obtaining a face image through feature point extraction or the like, and attaching and specifying an identity number (ID, etc.). Then, when the identified player 6 leaves and arrives at another gaming table, the control device 14 has a warning function to notify the presence of the specific player at the other gaming table. Specifically, it notifies the pit manager who manages each gaming table 4 and each table responsible person (which may be a dealer), in order to prevent further special phenomena.

[0067] The control device 14 further includes a database that retains a history of the exchange of bills K and gaming substitute currency 120. It refers to the database at regular intervals or on a daily basis, and compares and determines whether the amount of the gaming substitute currency 120 grasped in the gaming substitute currency tray 17 of the dealer 5 at the gaming table 4 has increased or decreased according to the total amount of the payment amount of the gaming substitute currency 120 corresponding to the exchanged bill K or the payment amount of the bill K corresponding to the exchanged gaming substitute currency 120.

[0068] In the above example, it is also possible to monitor the win-loss history for each play position 7 and the amount of gaming substitute currency obtained (the amount won) without identifying individual players 6. In this case, although it is not possible to track the player 6 when each player 6 leaves, it is possible to detect special situations such as a state where the amount of gaming substitute currency wagered when losing at a specific play position 7 on one gaming table 4 is small and the amount of gaming substitute currency wagered when winning is large continuing for several games. And when such a play position 7 is detected, there is a suspicion of fraud or error at that play position 7. By verifying the video taken of that play position 7, fraud or error can be discovered.

[0069] Specifically, the camera device 2 is installed so as to photograph at least the gaming substitute currency 120 placed in the bet area 8 of the gaming table 4. The image analysis device 12 analyzes the image captured by the camera device 2 to detect for each user position 7 at which position among the player, banker, and tie positions in the bet area 8 the gaming substitute currency is placed and the amount of the placed gaming substitute currency. Further, the card distribution device 3 also functions as a win / loss result determination device and determines the win / loss result of the game. The control device 14 records (monitors) the win / loss history and the amount of the obtained gaming substitute currency (gaming substitute currency acquisition amount) for each play position 7 based on the position (player, banker, or tie) within the bet area 8 where the gaming substitute currency 120 is placed and the win / loss result of the game. Note that only either the win / loss history or the gaming substitute currency acquisition amount may be recorded. When the history of this win / loss history and / or the gaming substitute currency acquisition amount is a special situation (set by the casino) compared to the statistical data of a large number (big data) of past games, the control device 14 identifies this player position 7 as a play position suspected of cheating.

[0070] When cheating is suspected for a certain player position 7, the fraud detection system may generate an alarm (light, sound, or vibration) so that at least the dealer can be near at that time. Thereby, it is possible to prevent the continuation of cheating, such as interrupting the subsequent game at least on the spot. Further, information indicating that cheating is suspected may be added to the video captured and recorded by the camera device 2. Thereby, the cause of the suspicion of cheating can be investigated by checking the video.

[0071] The fraud detection system in a casino having a gaming table in this embodiment further has a function of inspecting the exchange between bills and gaming tokens, which is often carried out on the gaming table 4. In a casino such as a casino, before the game, the player 6 exchanges bills (such as cash) for gaming tokens at a predetermined gaming token exchange. However, when the player 6 runs out of gaming tokens, without leaving the gaming table 4, the player can exchange cash (bills) for gaming tokens 120 on the gaming table (such as a baccarat table) and continue the game. However, this creates an opportunity for fraud between the dealer 5 and the player. The exchange of cash (bills) for gaming tokens 120 on the gaming table (such as a baccarat table) needs to be carried out when the game is not in progress. The card dealing device 3 can detect the start and end of card dealing (the time of determining the win or loss) in order to determine the outcome of the game. Therefore, in the card dealing device 3, situations other than card dealing are detected, and the control device 14 detects that the exchange between bills and gaming tokens 120 is being carried out on the gaming table 4 in situations other than during card dealing (as shown in FIG. 5). Whether it is during card dealing (or other situations) can be detected based on information obtained from the operation of the card dealing device 3 or the dealer 5.

[0072] The control device 14 can perform image analysis on the surface of the bill K to recognize the number and amount of the bills. Further, on the gaming table 4, whether the bill K for exchange with the gaming token 120 is genuine is detected by irradiating a black light to detect the genuine mark G of the bill. As shown in FIG. 5, the control device 14 also performs image analysis and verification on this genuine mark G, recognizes the total amount of genuine bills, and can recognize the total amount of gaming tokens even when a plurality of gaming tokens placed on the gaming table as exchange targets are hidden due to the blind spot of the camera device 2. It has an artificial intelligence utilization type or a deep learning structure that can compare the total amount of the bills K issued from the player on the gaming table 4 with the total amount of the gaming tokens 120 issued from the dealer 5 and determine whether the amounts of both are the same.

[0073] The control device 14 is of an artificial intelligence utilization type or a deep learning structure capable of comparative calculation as to whether the total amount of the game substitute currency 120 in the game substitute currency tray 17 of the dealer 5 on the game table 4 increases or decreases according to the payment amount of the game substitute currency corresponding to the exchanged bills after the exchange between the bills and the game substitute currency is made and settled. It is conceivable that the total amount of the game substitute currency 120 in the game substitute currency tray 17 of the dealer 5 is always grasped in advance by means of RFID or the like of the game substitute currency 120. Also, by photographing the game substitute currency tray 17 containing the game substitute currency 120 with the camera device 2 and analyzing the image with the image analysis device 12, the total amount of the game substitute currency 120 stored in the game substitute currency tray 17 can be detected.

[0074] Also, the control device 14 verifies whether the increase or decrease in the amount of the game substitute currency 120 in the game substitute currency tray 17 before and after the exchange between the bills and the game substitute currency matches the exchange amount of the game substitute currency in the image analysis result on the game table 4. The amount of the paid bill may be input to the control device 14 by the dealer 5 through key input or the like, or may be specified by photographing the game table 4 where the bill is paid with the camera device 2 and analyzing the image with the image analysis device 12.

[0075] As described above, the control device 14 determines whether the amount of reduction of the game substitute currency 120 from the game substitute currency tray 17 due to the exchange between the bills and the game substitute currency matches the amount of the bill paid from the player 6 to the dealer 5. Further, the control device 14 is an intelligent control device capable of comparative calculation of the coincidence or non - coincidence between the deposit amount of the bill (usually by key input or the like) by the dealer 5 and the calculated amount of the bill in the image analysis result by the image analysis device 12 after the exchange between the bills and the game substitute currency is made and settled, and may further be of an artificial intelligence utilization type or a deep learning structure.

[0076] Furthermore, the control device 14 is an artificial intelligence utilization type or deep learning structure capable of comparing and calculating the match or mismatch between the total amount of bills input by the dealer in the game table 4 assigned to the dealer and the total amount of bills based on the image analysis result by the image analysis device 12.

[0077] The control device 14 compares and determines whether the amount of the game substitute currency 120 grasped in the game substitute currency tray 17 of the dealer 5 of the game table 4 has increased or decreased according to the payment amount of the game substitute currency 120 corresponding to the exchanged bills or the payment amount of the bills corresponding to the exchanged game substitute currency 120 after the exchange between the bills and the game substitute currency 120 is performed.

[0078] The control device 14 is a control device of an artificial intelligence utilization type or deep learning structure capable of obtaining information on the type and number of the game substitute currency 120 even when a part or the whole of one piece of the game substitute currency is in a hidden state when measuring and determining the type and number of the game substitute currency 120.

[0079] (Second Embodiment) The management system of the second embodiment relates to a management system for table games in a casino.

[0080] In a casino or the like, attempts have been made to prevent handling mistakes of various dealers' game substitute currencies (game substitute currencies). The casino is equipped with a monitoring camera for monitoring handling mistakes of the dealer's game substitute currencies, and prevents mistakes and frauds such as the collection or repayment of game substitute currencies different from the winning and losing results determined from the images obtained from the monitoring camera.

[0081] On the other hand, it has been proposed to attach an IC tag to each game substitute currency to grasp the amount of the game substitute currency in order to grasp the number and total amount of the wagered game substitute currencies.

[0082] In the card game monitoring system described in International Application PCT / JP2015 / 000171, it is determined whether the gaming substitute currency placed on the gaming table is collected or reimbursed according to the winning or losing result by analyzing the movement of the gaming substitute currency through image analysis, and monitoring of the dealer's handling mistakes of the gaming substitute currency is performed.

[0083] In a gaming establishment such as a casino, gaming substitute currency is piled up in large amounts and placed on the gaming table. However, there is a problem that the total amount cannot be accurately read by the IC tag reader provided under the gaming table. If the sensitivity of the reader is increased, there is a problem that the gaming substitute currency placed at different positions (the winning or losing depends on the position) is combined and the total amount of the gaming substitute currency for each position cannot be grasped. Conventionally, as shown in FIG. 7, the pattern of the gaming substitute currency (gaming substitute currency) 9 is complex. When a large number of gaming substitute currencies are stacked, there is a problem that the number of stacked coins cannot be accurately grasped by the camera.

[0084] In addition, it has been recognized that the fraud on the gaming table has become sophisticated, and there is a new problem that fraud by sophisticated betting methods that cannot be detected by simply detecting that the amount won on the gaming table is large cannot be detected by the camera.

[0085] In addition, the dealer needs to collect or reimburse the gaming substitute currency placed on the gaming table according to the winning or losing result. Even if an attempt is made to determine this by analyzing the image of the gaming substitute currency, since the pattern of the gaming substitute currency (gaming substitute currency) is complex, it cannot be determined by the existing practical image analysis technology whether the dealer accurately reimbursed the gaming substitute currency corresponding to the wagered gaming substitute currency at the time of reimbursement, and there is a problem that prevention of mistakes is not sufficient.

[0086] To solve the above various problems, the table game management system according to this embodiment includes a card distribution device that determines and displays the win / loss results of each game on a gaming table, a measuring device that measures the types and numbers of substitute gaming currency placed on the gaming table using a camera, and a management control device that identifies and stores the positions, types, and numbers of substitute gaming currency placed on the gaming table by game participants using the measurement results of the measuring device in each game. The substitute gaming currency has a multi-layer structure in which a plurality of plastic layers of different colors are laminated, with at least a colored layer in the middle, and a white layer or a light-colored layer is laminated on both sides of the middle colored layer to form a stripe pattern in the lamination direction on the side surface. The type of substitute gaming currency can be identified by the colored layer. The management control device has a computing function that determines the winners and losers of the participants in each game and calculates the casino-side revenue and expenditure on the gaming table for each game using the win / loss results obtained from the card distribution device and the measurement results of the positions, types, and numbers of substitute gaming currency placed by the game participants.

[0087] Furthermore, there is a management system. The management control device has a structure with a function of measuring the number of colored layers, white layers, or light-colored layers of the substitute gaming currency placed by each game participant to determine the number of substitute gaming currency.

[0088] To solve the above various problems, the substitute gaming currency according to this embodiment has a multi-layer structure in which a plurality of plastic layers of different colors are laminated, with at least a colored layer in the middle, and white layers or light-colored layers are laminated on both sides of the colored layer to form a stripe pattern in the lamination direction on the side surface. The type of substitute gaming currency can be identified by the colored layer.

[0089] Furthermore, the substitute gaming currency has printing representing the type of substitute gaming currency on the surface of the white layer or the light-colored layer, a transparent layer is provided on the outermost layer, and each layer is thermally bonded to form at least a five-layer structure.

[0090] Furthermore, the substitute gaming currency may be one having a mark made of UV ink or infrared-absorbing ink (carbon black ink) on the surface of the white layer or the light-colored layer, or the outermost transparent layer may be embossed, or the edge of the outermost transparent layer may be R-processed, or the colored layer may be formed of a plurality of layers, and further, the colored layer may incorporate an RFID.

[0091] In order to solve the above various problems, an inspection device for inspecting the substitute gaming currency of the present embodiment includes a passage having an entrance and an exit through which the substitute gaming currency can pass in the radial direction, a determination device for determining the type of substitute gaming currency by photographing the side surface of the substitute gaming currency passing through the passage and determining the color of the stripe pattern in the stacking direction of the side surface, a mark reading device for reading a mark made of UV ink or infrared-absorbing ink (carbon black ink) provided on the surface of the passing substitute gaming currency, a print inspection device for reading the print representing the type provided on the surface of the substitute gaming currency from a direction perpendicular to the passage, and a control device for the entire device. The control device is configured to inspect whether the type of substitute gaming currency determined by the determination device for the type of substitute gaming currency matches the content of the print representing the type obtained from the print inspection device.

[0092] According to the system of the present embodiment, even if a large number of substitute gaming currencies (substitute gaming currencies) are stacked, the number of substitute gaming currencies can be determined by image analysis, and the total amount of the relatively overlapping substitute gaming currencies can be grasped by the position and color.

[0093] Hereinafter, with reference to the drawings, a management system for table games in a casino having a game table according to an embodiment of the present invention will be described. FIG. 6 is a diagram showing an overall overview of the system. A management system for table games in a casino having a plurality of game tables 4 records the progress state of the game being played on the game table 4 as video via a plurality of camera devices 2 including game participants 6 and a dealer 5, and further includes an image analysis device 18 that analyzes the video of the recorded game progress state. The measuring device 19 is provided, and further, a card distribution device 3 that determines and displays the winning and losing results of each game on the game table 4 is provided. The card distribution device 3 is a so-called electronic shoe that is already known and used by those skilled in the art, and the rules of the game are programmed in advance, and it has a structure that can read the information (rank and suit) of the distributed card C and determine the winning and losing of the game. For example, in the baccarat game, the win of the banker, the win of the player, and a tie (draw) are basically determined by the ranks of two to three cards each, and the determination result (winning and losing result) is displayed on the display lamp 13.

[0094] The management control device 14 reads the information (rank and suit) of the card C obtained from the card distribution device 3 to determine the winning and losing results of each game, and uses the measurement results of the position, type, and number of the gaming tokens 120 placed by the game participant 6 to determine the winners 6W and losers 6L among the participants 6 in each game. Further, it has a computing function that performs, for each game, the calculation of subtracting the total amount of the gaming tokens 120 repaid to the winners 6W among the participants 6 from the total amount of the casino-side revenue calculation (the gaming tokens 120 bet by the losers 6L) on the game table 1.

[0095] The image analysis device 18, the measurement device 19, and the management control device 14 in this detection system have a structure that comprehensively includes a computer, a program, and a memory composed of an integrated or multiple configurations.

[0096] Next, the details of the substitute game currency used in this detection system will be described. FIG. 8 is a front sectional view of the substitute game currency 120 used in this detection system. A plurality of plastic layers of different colors are laminated, and at least a colored layer 121 is provided in the middle. A white layer 122 or a light-colored layer (not shown, as long as it is a layer lighter in color than the colored layer 121) is laminated on both sides of this middle colored layer 121, resulting in a multi-layer structure. By having such a colored layer 121 and laminating a white layer 122 or a light-colored layer (not shown, as long as it is a layer lighter in color than the colored layer 121) on both sides of this middle colored layer 121, as shown in FIG. 9A, a stripe pattern in the lamination direction is formed on the side surface. By changing the color of the colored layer 121 (such as red, green, yellow, or blue) for each type of substitute game currency 120 (10 points, 20 points, 100 points, 1000 points, etc.), the type of substitute game currency 120 can be specified.

[0097] The substitute game currency 120 has a structure having at least a colored layer 121 and a white layer 122 or a light-colored layer in terms of appearance so as to form an axial stripe pattern on the side surface, and has a configuration capable of specifying the type of substitute game currency 120 by the colored layer 121. FIGS. 10A and 10B are examples of different embodiments, respectively, and are examples in which the colored layer 121 and the white layer 122 or the light-colored layer are formed by injection molding. First, the colored layer 121 is molded in a molding die (not shown), and then the white layer 122 or the light-colored layer is molded, which is made by so-called two-color molding.

[0098] Furthermore, as shown in FIG. 9B, on the surfaces (upper and lower surfaces) of the white layer 122 of the substitute game currency 120, there is printing 123 (such as 100 points) indicating the type of the substitute game currency 120. As shown in FIG. 8, a transparent layer 124 is provided on the outermost layer, and the layers are thermocompression bonded to form at least a five-layer structure. These substitute game currencies 120 are made of an elongated plastic material, and in the elongated state, the layers (colored layer 121, white layer 122, transparent layer 124) are thermocompression bonded to form an adhered state (such as a five-layer structure), and then punched into a circular or rectangular shape by pressing or the like. When punching by pressing, the dimensions of the die and punch of the mold for punching are designed so that the edge of the outermost transparent layer 124 is subjected to R processing (rounded corners).

[0099] That is, when manufacturing the substitute game currency 120, first, a plate-shaped plastic colored layer 121 and a plate-shaped plastic white layer 122 or light-colored layer are laminated to form a laminated structure composed of a plurality of plastic layers. Then, a pattern is printed on the upper and lower surfaces of this laminated structure, and a transparent layer 124 is further provided thereon. Then, the layers of the laminated structure and the transparent layer 124 are heat-pressed and welded to create a substitute currency blank. The thus-formed substitute currency blank is punched by a mold to obtain a plurality of substitute game currencies 120 of a predetermined shape. During this punching process, the upper and lower corners on the outside of the substitute game currency 120 are subjected to R processing by the mold.

[0100] Furthermore, the gaming substitute currency 120 is provided with a face code made of UV ink or infrared-absorbing ink (carbon black ink) on the surface of the white layer 122 (see Fig. 9B). This face code represents the authenticity of the gaming substitute currency 120. When ultraviolet light (or infrared light) is applied, the mark becomes visible, and the combination of its shape and number represents the genuine one. Fig. 11 is a perspective view of the state where the gaming substitute currencies 120 are stacked, and the combination of the long code L and the short code S is the face code M. A transparent layer (printing layer) 124 is thermally pressed or coated on the outermost layer so as to cover the printing 123 and the face code. This transparent layer 124 is embossed to prevent the gaming substitute currencies 120 from adhering to each other. In this embodiment, an example of printing the face code on the surface of the white layer 122 has been described. However, instead of or together with the face code, either or both of a security mark and an optical variable device (OVD) may be printed.

[0101] The edge of the outermost transparent layer (printing layer) 124 with the printing 123 (such as 100 points) is subjected to R processing (R) to prevent the surface of the white layer 122 from being deformed and appearing on the side surface in the punching process of the gaming substitute currency 120. Also, the gaming substitute currency 120 has no sharp edge left, preventing damage to the hand or other gaming substitute currencies 120.

[0102] As shown in Fig. 8, the coloring layer 121 may be formed by a plurality of colored layers (three layers in Fig. 8). Since the plurality of colored layers (three layers in Fig. 8) are thermally pressed together, the three-layer structure as shown in Fig. 8 is not visible, and Fig. 8 shows three layers for explanatory purposes. Furthermore, a partial cutout B is provided in the middle layer of the three layers of the coloring layer 121, and an RFID 125 is built therein.

[0103] Note that the RFID 125 may be incorporated into the gaming token 120 by arranging it between the flat surface of the colored layer 121 and the flat surface of the white layer 122 without providing the cutout B in the colored layer 121 and then thermocompression bonding the colored layer 121 and the white layer 122 as they are. By configuring at least one of the colored layer 121 and the white layer 122 with a heat-deformable material such as plastic, the plastic layer of the colored layer 121 and the white layer 122 sandwiching the RFID 125 by thermocompression bonding is thermally deformed, so that the RFID 125 is closely fixed between those layers without providing the cutout B.

[0104] FIG. 12 is a perspective explanatory photographic view for explaining a state in which different types of gaming tokens are stacked. The management control device 14 images the gaming tokens 120 placed by the game participant 6 on the gaming table 1 with the camera device 2, and measures for each placed area 8 (whether it is bet on the banker, on the player, or on a pair (PAIR), or on a tie (TIE)) by the measuring device 19 equipped with the image analysis device 18. At the same time, the measuring device 19 analyzes and measures the number and color of the colored layer 121 (or light-colored layer) or the white layer 122 of the gaming tokens 120 stacked in each area (using the information obtained by the image analysis device 18) to determine the type and number of the gaming tokens 120. The management control device 14 controls the camera device 2 so that imaging by the camera device 2 is performed when the first card is drawn from the card distribution device, or before or after the draw, or after the sign of the dealer's bet is completed.

[0105] The management control device 14 may be a control device having an artificial intelligence utilization type or a deep learning structure. The management control device 14 can grasp the position 8 (the position bet on the player, the banker, or the pair), the type (the gaming substitute currency 120 has different value amounts assigned for each color), and the number of the gaming substitute currency 120 bet by each participant 6 via the camera device 2 and the image analysis device 18. In an artificial intelligence utilization type computer or control system, or in deep learning (structure) technology, using a self-learning function or the like, it is possible to grasp the position 8 (the position bet on the player, the banker, or the pair), the type (the gaming substitute currency has different value amounts assigned for each color), and the number of the gaming substitute currency 120. Therefore, according to the win / loss result of the game determined by the card distribution device 3 in each game, the management control device 14 determines whether the collection of the gaming substitute currency 120 bet by the losing participant 6L in each game (indicated by the arrow L) and the repayment (payment (120W)) of the winning gaming substitute currency 120 to the winning game participant 6W are properly performed according to the win / loss result of the game by analyzing the video of the game progress state via the image analysis device 18.

[0106] In such a case, as shown in FIG. 11 (compared with the conventional gaming substitute currency shown in FIG. 7), it has a laminated multi-layer structure, and the stripe pattern in the lamination direction is clearly formed on the side surface. Therefore, the measuring device 19 including the image analysis device 18 can easily and accurately measure the type and number of the gaming substitute currency. Furthermore, by using an artificial intelligence utilization type computer or control system, or deep learning (structure) technology, the analysis and determination of the image can be made more accurate. Since an artificial intelligence utilization type computer or control system, or deep learning (structure) technology is already known and available to those skilled in the art, a detailed description is omitted.

[0107] The management control device 14 can analyze and grasp the total amount of the substitute gaming currency 120 in the substitute gaming currency tray 17 of the dealer 5 on the gaming table 4 using the image analysis device 18. After the game ends and is settled, according to the recovery of the lost substitute gaming currency 120 wagered by each game participant 6 and the amount of payment 120W of the winning substitute gaming currency to the winning game participant 6W, it is possible to compare and calculate whether the total amount of the substitute gaming currency 120 in the substitute gaming currency tray 17 has increased or decreased according to the win-loss result of the game. Even if the total amount of the substitute gaming currency 120 in the substitute gaming currency tray 17 is constantly grasped by means such as RFID, whether the increase or decrease amount is correct or not is determined by the management control device 14 analyzing the video of the game progress state via the image analysis device 18. These may also utilize an artificial intelligence utilization type or a deep learning structure.

[0108] The management control device 14 grasps the position (player, banker, position wagered on a pair) and amount (type and number of pieces) of the substitute gaming currency wagered at each play position 7 on the gaming table 4, and compares the win-loss history of each game participant 6 obtained from the win-loss result of each game and the amount of substitute gaming currency obtained (winning amount) with the statistical data of a large number (big data) of past games, and it may be an artificial intelligence utilization type or a deep learning structure that can extract it as a special situation (set by the casino). Typically, the occurrence of a winning amount of a certain amount (one million dollars) or more, or at a play position 7 on a certain gaming table 4, where the amount of substitute gaming currency wagered when losing is small and the amount of substitute gaming currency wagered when winning is large, continues for several games, and it is possible to extract this as a special situation compared to the statistical data (big data, etc.) of past games. It is equipped with a management control device 14 of an artificial intelligence utilization type or a deep learning structure.

[0109] The management control device 14 has a structure that can compare and calculate whether the increase or decrease of the substitute gaming currency corresponding to the settlement is correct after the total amount of the substitute gaming currency 120 in the substitute gaming currency tray 17 of the dealer 5 on the gaming table 4 is settled after the settlement with the substitute gaming currency 120 wagered by each participant 6 after each game.

[0110] In the game substitute currency tray 17 for holding the game substitute currency 120 of the dealer 5 shown in FIG. 6, by measuring the number and color of the colored layer 121 or white layer 122 of the game substitute currency 120 stacked in the horizontal direction using the measuring device 19 (using the information obtained by the image analysis device 18), the type and number of the game substitute currency 120 can be determined. The total amount of the game substitute currency 120 in the holding game substitute currency tray 17 is always (or at a predetermined time interval) grasped in this way. The management control device 14 has a computer function for calculating the settlement amount of each game (the amount obtained by subtracting the total amount of the game substitute currency 120 repaid to the winner 6W among the participants 6 from the total amount of the game substitute currency 120 bet by the loser 6L in the casino side's income and expenditure calculation on the game table 4) for each game (see the above reference). Therefore, the total amount of the game substitute currency 120 in the game substitute currency tray 17 is always (or at a predetermined time interval) verified. That is, it is verified whether the increase or decrease of the game substitute currency matches the image analysis result by the image analysis device 18 and the settlement amount of each game by the dealer 5.

[0111] FIG. 13A is a diagram showing details of the game substitute currency tray of the present embodiment, and FIG. 13B is a diagram showing another example of the game substitute currency tray. The game substitute currency tray 17 is provided with a recovery game substitute currency tray 171 for collecting and temporarily storing the game substitute currency 120L bet by the losing player 6L and a repayment game substitute currency tray 172 for storing the game substitute currency 120W to be repaid. The image analysis device 12 and the control device 14 grasp the position, type, and number of the game substitute currency 120L bet by the losing player 6L, and calculate the increased amount of the game substitute currency 120L in the game (the amount that should be of the game substitute currency 120 in the recovery game substitute currency tray 171). Further, the image analysis device 12 and the control device 14 grasp the actual total amount of the game substitute currency 120 in the game substitute currency tray 171 after collection, and compare the should-be total amount with the actual total amount to determine whether there is a difference.

[0112] Here, the game substitute currency tray 17 shown previously has a two-stage structure consisting of an upper-stage game substitute currency tray 17a and a lower-stage game substitute currency tray 17b. FIGS. 14A and 14B are diagrams showing the relationship between the two-stage game substitute currency tray 17 and the camera device 2. FIG. 14A shows the state where the two stages are stacked, and FIG. 14B shows the state where the two stages are shifted. There is a lower-stage game substitute currency tray 17b below the upper-stage game substitute currency tray 17a, and they are connected to each other by a hinge 17c. When the game substitute currency 120 in the upper-stage game substitute currency tray 17a is insufficient, the game substitute currency 120 is replenished from the lower-stage game substitute currency tray 17b to the upper-stage game substitute currency tray 17a. When the game substitute currency 120 in the upper-stage game substitute currency tray 17a becomes excessive, the game substitute currency 120 is moved to the lower-stage game substitute currency tray 17b.

[0113] In order to take in and out the game substitute currency 120 from the lower-stage game substitute currency tray 17b, the upper-stage game substitute currency tray 17a is moved by the hinge 17c to the state shown in FIG. 14B. In the state of FIG. 14A, the upper-stage game substitute currency tray 17a is imaged by the camera device 2, and in the state of FIG. 14B, the lower-stage game substitute currency tray 17b can be imaged by the camera device 2. In the state of FIG. 14B, further, the upper-stage game substitute currency tray 17a and the lower-stage game substitute currency tray 17b can be imaged simultaneously and in a distinguishable state from each other by the camera device 2c. Also, in the state of FIG. 14B, the upper-stage game substitute currency tray 17a and the lower-stage game substitute currency tray 17b may be photographed separately. The camera devices 2 and 2c are either a visible light camera or an infrared camera corresponding to the ink printed with the side ID 126 alone, or a camera capable of switching between a plurality of functions of a visible light camera and an infrared camera corresponding to the printed ink.

[0114] Next, with reference to FIG. 15, an inspection apparatus 200 for inspecting the gaming substitute currency 120 which is an embodiment of the invention of the present application will be described. The inspection apparatus 200 includes a passage 203 having an inlet 201 and an outlet 202 through which the gaming substitute currency 120 can pass in the radial direction (arrow Y direction). The passage 203 is inclined, and the gaming substitute currency 120 passes in the direction of arrow Y. In the passage 203, there are provided a determination device 204 for determining the type of the gaming substitute currency by photographing the side surface of the gaming substitute currency 120 and determining the color of the stripe pattern in the lamination direction of the side surface, a mark reading device 205 for reading a face code as a face code by UV ink or ink (carbon black ink) that absorbs infrared rays provided on the surface of the passing gaming substitute currency 120, a print inspection device 206 for reading a print 123 indicating the type provided on the surface of the gaming substitute currency from a direction perpendicular to the passage 203, and a control device 207 for the entire apparatus. The control device 207 is configured to inspect whether or not the type of the gaming substitute currency determined by the determination device 204 for the type of the gaming substitute currency matches the content of the print indicating the type obtained from the print inspection device 206.

[0115] With this inspection apparatus 200, it is possible to inspect whether or not the print 123 of the manufactured gaming substitute currency 120 is correctly printed in accordance with the type of the gaming substitute currency based on the color of the stripe pattern of the gaming substitute currency 120.

[0116] As described above, the gaming substitute currency 120 of the present embodiment has a laminated structure composed of a plurality of plastic layers in which a colored layer 121 and a white layer 122 or a light-colored layer sandwiching the colored layer 121 are laminated, and thereby a stripe pattern is formed in the lamination direction on the side surface. The gaming substitute currency 120 has a configuration in which the type of the gaming substitute currency 120 can be specified by the colored layer 121 appearing on the side surface. Further, printing is performed on the upper surface and the lower surface of the gaming substitute currency 120. Specifically, printing is performed on the surface of the white layer 122 or the light-colored layer, and a transparent layer 124 is provided on the upper surface thereof. The colored layer 121, the white layer 122 or the light-colored layer, and the printing layer 124 form a layer structure with thermocompression bonding between the layers.

[0117] The white layer 122 or the light-colored layer sandwiching the coloring layer 121 may be configured to have different thicknesses at the top and bottom.

[0118] Also, in this embodiment, the outer edges of the upper and lower surfaces of the gaming substitute currency 120 are subjected to R processing. Thereby, it is possible to prevent the hands of the player handling the gaming substitute currency 120 from being injured or other gaming substitute currencies 120 from being damaged.

[0119] Also, in this embodiment, the RFID 125 is closely fixed between the plastic layers forming any one of the coloring layer 121, the white layer 122, or the light-colored layer.

[0120] Also, in this embodiment, on the upper surface and / or the lower surface of the gaming substitute currency 120, a face code is provided by an infrared absorption ink such as a UV-emitting ink or an ink that absorbs infrared rays (carbon black ink). Further, as a modification of this embodiment, instead of the face code, or together with the face code, either or both of a security mark and an optical variable device (OVD) may be printed on the surface of the gaming substitute currency 120.

[0121] Also, the gaming substitute currency 120 of this embodiment has a structure in which a side ID 126 is attached to the side and the RFID 125 is built in, and a face code by a UV-emitting ink or an infrared absorption ink is provided on the upper surface or the lower surface (printing layer 124). And the information of the side ID 126 is associated with the information of the RFID 125, or the information of the side ID 126 is associated with the information of the face code, or the information of the side ID 126, the information of the RFID 125, and the information of the face code are associated.

[0122] In addition, the inspection device 200 of the present embodiment includes a measuring device 19 for the type of substitute gaming currency 120 that photographs the side surface of the substitute gaming currency 120 and determines the color of the stripe pattern in the stacking direction of the side surface, and a mark reading device 205 that reads the printing of the substitute gaming currency. Thereby, the relationship between the type of substitute gaming currency and the printed content can be inspected.

[0123] The management control device 14 of the present embodiment performs imaging for discriminating the position, type, and number of substitute gaming currency placed by game participants in each game when the first card is drawn from the card distribution device 3, or before or after the card is drawn, or after the sign of the dealer's bet is completed.

[0124] In addition, the substitute gaming currency 120 of the present embodiment is manufactured as follows. First, a colored layer 121 and a white layer 122 or a light-colored layer are heat-pressed to form a laminated structure including a plurality of plastic layers. Then, a pattern is printed on at least the upper surface or the lower surface of the laminated structure to create a substitute currency blank. Then, the substitute currency blank is punched by a die to obtain a plurality of substitute gaming currency of a predetermined shape. Here, during the punching process, the outer edges of the upper and lower surfaces of the substitute gaming currency 120 are R-processed by a die.

[0125] In addition, when manufacturing the substitute gaming currency 120 having a side ID, the side ID is inkjet-printed on the side surface of the white layer 122 or the light-colored layer. In addition, when manufacturing the substitute gaming currency 120 having an RFID, the RFID is sandwiched between the layers of the laminated structure, and the layers sandwiching the RFID are heat-welded when each layer is heat-pressed, and the periphery of the RFID is adhered with a plastic layer.

[0126] In addition, the table game management system of the present embodiment includes a card distribution device 13 that determines and displays the win / loss results of each game on the gaming table 4, a camera device 2 that captures images of the gaming substitute currency 120 placed on the gaming table 4, and a management control device 14 that uses the imaging result of the camera device 2 to identify, store, and remember the position, type, and number of the gaming substitute currency placed by the game participant 6 on the gaming table 4. The gaming substitute currency 120 is a laminated structure in which a colored layer 121 and a white layer 122 or a light-colored layer are laminated, and has a stripe pattern in the lamination direction on the side surface. The management control device 14 has a computing function that performs, for each game, the calculation of the casino side's revenue and expenditure on the gaming table 4 based on the win / loss result obtained from the card distribution device 13 and the position, type, and number of the gaming substitute currency 120 identified using the imaging result of the camera device 2.

[0127] The management control device 14 has a function of measuring the number of the colored layer 121 or the white layer 122 or the light-colored layer of the gaming substitute currency 120 placed by each game participant 6, and determining the type and amount of the gaming substitute currency based on the color of the colored layer 121 to determine the number of the gaming substitute currency 120.

[0128] (Third Embodiment) The system of the present embodiment relates to a management system for gaming substitute currency that prevents counterfeit gaming substitute currency from being used in a casino or other gaming facility that uses gaming substitute currency.

[0129] Among many live table games played in casinos and gaming facilities, there are baccarat and blackjack. These games use a standard deck of 52 playing cards and are played on a game table with multiple decks (6 to 9 or 10 decks) that have been shuffled in advance and distributed from a shoe. In casinos and gaming facilities, gaming substitute currency is used for such games.

[0130] The use of counterfeit gaming tokens must not occur in a casino. To prevent the use of counterfeit gaming tokens in a casino, there is a technology in the casino that attaches RFID to gaming tokens to prevent the use of counterfeits. RFID-attached gaming tokens are well-known and are disclosed in International Application Publication No. WO2008 / 120749.

[0131] This embodiment provides a management system for preventing the use of counterfeit gaming tokens used in a casino or a gaming facility, or provides gaming tokens, and can prevent the use of counterfeit gaming tokens and illegal exchanges in a casino or a gaming facility. In recent years, the manufacturing technology of counterfeit gaming tokens has evolved, and the technology has advanced to the point where genuine authenticity verification marks and RFID can be almost perfectly copied. As a result, there is a problem that counterfeit gaming tokens are attached with the same genuine authenticity verification marks and RFID as the real ones, making it impossible to distinguish between counterfeits and genuine gaming tokens, and almost impossible to determine authenticity.

[0132] To solve the above-described conventional problems, the gaming substitute currency management system according to the present embodiment includes gaming substitute currency with an individually identifiable side ID, an ID reader that reads the side ID attached to the gaming substitute currency, a vault in which the gaming substitute currency is held by a casino cashier, a gaming table gaming substitute currency tray in which the gaming substitute currency is held on a gaming table, a gaming substitute currency determination device that specifies the type and number of the gaming substitute currency held in the gaming table gaming substitute currency tray and the vault using the ID reader, and a management control device that manages the ID attached to the gaming substitute currency in a database in a casino. The management control device registers in advance the ID of the gaming substitute currency assumed to be used in the database, and using the database, manages on the database at least the ID of the gaming substitute currency existing on the gaming table gaming substitute currency tray and the vault together with its location information. The gaming substitute currency in the gaming table gaming substitute currency tray and the vault is specified at a predetermined timing and the database is searched to determine the following events by searching the database: 1) an ID that did not exist in the database newly exists; 2) two or more identical IDs exist. If there is a situation of 1) or 2) above, it is equipped with a function of generating an error signal.

[0133] Furthermore, when there is a change in the presence of the game substitute currency in at least the game substitute currency tray for the game table game and the storage, the management control device further associates the time or location of the change with the ID and records it on the database. If there is a situation where two or more identical IDs exist by searching the database, the ID and the information on the time or location recorded on the database in association with the ID are extracted and saved from the database, and the time when the game substitute currency with the previously detected ID entered or exited the game substitute currency tray for the game table game or the storage, or the location of the game substitute currency tray for the game table game or the storage where the game substitute currency was held can be specified.

[0134] Furthermore, in the game substitute currency management system, a game substitute currency determination device for the bet area that specifies the type and number of the game substitute currency bet on the bet area of the game table using the ID reader is provided. For the ID of the game substitute currency existing on the bet area of the game table, the following events are also determined by searching the database: 1) a newly existing ID that did not exist in the database; 2) the existence of two or more identical IDs. If there is a situation of 1) or 2) above, it may be provided with a function of generating an error signal.

[0135] Furthermore, the side ID is attached to at least three locations on the side surface of the game substitute currency. The side ID is attached by inkjet printing with ink visible in visible light. In particular, a configuration where the side ID is attached by the presence or absence of marks in multiple rows and multiple columns is advantageous. Furthermore, a transparent coating layer or varnish is provided on the upper and lower surfaces of the game substitute currency.

[0136] In order to solve the above-mentioned conventional problems, the substitute gaming currency of the present embodiment has a multi-layer structure in which a plurality of plastic layers of different colors are laminated, at least one layer is provided with a colored layer, and a white layer or a light-colored layer is laminated outside the colored layer, so that a stripe pattern in the lamination direction is formed on the side surface, and the type of the substitute gaming currency can be specified by the colored layer. In addition, side IDs are attached to at least three locations on the side surface of the side white layer or the light-colored layer, and by reading the IDs with an ID reader, the type and manufacturing information of the substitute gaming currency can be specified, and the IDs can be managed on a database. And the side ID may be attached by inkjet printing with ink (visible ink) visible to visible light. The side ID may be attached by inkjet printing with ink (ink that absorbs infrared rays, UV ink, etc.) invisible to visible light. Further, the side ID may be printed with at least two of visible ink, ink that absorbs infrared rays, or UV ink.

[0137] In order to solve the above-mentioned conventional problems, the substitute gaming currency of the present embodiment is provided with an individually identifiable side ID, the side ID attached to the substitute gaming currency is read by an ID reader, and the ID reader can read the substitute gaming currency held in the vault held by the caster in the game hall and the substitute gaming currency tray for the game table on the game table. Further, the type and number of the substitute gaming currency held in the substitute gaming currency tray for the game table and the vault are specified by a substitute gaming currency determination device via the ID reader, and the ID of the substitute gaming currency existing on the substitute gaming currency tray for the game table and the vault is managed on a database together with its location information. At least 1) the situation that an ID that did not exist in the database newly exists, and 2) the situation that two or more identical IDs exist are inspected, and it is provided with the ID capable of determining the occurrence of the situation of 1) or 2) above.

[0138] Hereinafter, with reference to the drawings, a management system for gaming substitute currency in a gaming hall having a gaming table according to an embodiment of the present invention will be described. FIG. 16 is a diagram showing an overall overview of the system. The management system for gaming substitute currency in a gaming hall having a plurality of gaming tables 4 (only one is shown in FIG. 16) images, stores, and manages the progress state of the game performed on the gaming table 4 via a plurality of camera devices 2, including game participants 6 and dealers 5. In particular, the management system for this gaming substitute currency identifies the types and quantities of the gaming substitute currency 120 used in the game on the gaming table 4 by analyzing the image information obtained by the camera device 2. A side ID 126 is attached to the side surface of the gaming substitute currency 120, and the types and quantities of the gaming substitute currency 120 are obtained by determining and reading the side ID 126. In this specification, the terms "side ID" or "ID" are used in the sense of the physical ID attached to the side surface of the gaming substitute currency 120 and also in the sense of the identification information it represents. It is the ID reading device 53 inside the management control device 50 connected to the camera device 2 that analyzes the image information obtained from the camera device 2 to identify the side ID 126. In particular, the management control device 50 has inside it a gaming substitute currency determination device 52 that analyzes the image data captured via the camera device 2 and identifies the types and quantities of the gaming substitute currency 120 arranged side by side or stacked from the reading result of the side ID 126.

[0139] In addition, the management system of the present embodiment is configured to photograph the gaming substitute currency 120 on the gaming table 4 with a plurality of camera devices 2b-1 and 2b-2 having different heights and arranged at predetermined positions, in addition to the camera device 2 that photographs and records the gaming substitute currency 120. The camera device 2b-1 can image the gaming substitute currency 120 relatively far away on the gaming table 4, and the camera device 2b-2 is configured to image the gaming substitute currency 120 relatively close to the gaming table 4. By imaging with the two camera devices 2b-1 and 2b-2, it is possible to image the gaming substitute currency 120 in a place that would be a blind spot with only one camera.

[0140] The gaming substitute currency 120 is exchanged for the cash 61 paid by the game participant 6 at a plurality of cashiers 60 in the casino. At each cashier 60, the gaming substitute currency 120 is stored in a vault 62 that holds it. At each cashier 60 in the casino, the gaming substitute currency 120 brought in by the game participant 6 is also paid back in cash 61. At the gaming table 4, the gaming substitute currency 120 is held by the gaming table gaming substitute currency tray 17. The dealer 5 collects the gaming substitute currency 120 wagered by the game participant 6 who lost in each game from the table 4, returns it to the gaming table gaming substitute currency tray 17, and then reimburses the game participant 6 who won in each game with the gaming substitute currency 120. All such exchanges between the game participant 6 and the cashier 60 in the casino, or between the dealer 5, are imaged and recorded by the camera device 2. In the vault 62 and the gaming table gaming substitute currency tray 17, the amount of the gaming substitute currency 120 stored in the vault 62 and the gaming table gaming substitute currency tray 17 increases or decreases each time there is an exchange of the gaming substitute currency 120 with the game participant 6. The types and quantities of the gaming substitute currency 120 held in the gaming table gaming substitute currency tray 17 and the vault 62 are monitored at a predetermined timing or constantly by the ID reader device 53 and the gaming substitute currency determination device 52 via the camera device 2. The management control device 50 pre-holds on the database 51 the side ID 126 of all the gaming substitute currency 120 assumed to be used in the casino (in the casino, the side ID 126 of all the gaming substitute currency 120 assumed to be used is registered).

[0141] In this embodiment as well, the substitute game currency tray 17 may be composed of an upper-stage substitute game currency tray 17a and a lower-stage substitute game currency tray 17b in two upper and lower stages as described with reference to FIGS. 14A and 14B. Thereby, in the state of FIG. 14A, the upper-stage substitute game currency tray 17a can be imaged by the camera device 2, and in the state of FIG. 14B, the lower-stage substitute game currency tray 17b can be imaged by the camera device 2. Further, in the state of FIG. 14B, the upper-stage substitute game currency tray 17a and the lower-stage substitute game currency tray 17b can also be imaged simultaneously and in a distinguishable state by the camera device 2c. Also, in the state of FIG. 14B, the upper-stage substitute game currency tray 17a and the lower-stage substitute game currency tray 17b may be photographed separately. The camera devices 2 and 2c are either a visible light camera or an infrared camera corresponding to the ink printed with the side ID 126 alone, or a camera capable of switching between a plurality of functions of a visible light camera and an infrared camera corresponding to the printed ink.

[0142] In this way, the management control device 50 that manages the side ID 126 attached to the substitute game currency 120 on the database uses the database 51 to manage all the side IDs 126 of the substitute game currency 120 existing at least on the substitute game currency tray 17 for the game table and in the storage 62 in the game arcade together with their location information (such as in the storage 62, the substitute game currency tray 17 for the game table, or during movement from the backyard (not shown), or held by the game participant 6, etc.) on the database 51. The management control device 50 identifies all the substitute game currencies 120 in the substitute game currency tray 17 for the game table and the storage 62 by the side ID 126 at a predetermined timing or constantly, and searches the database 51 to determine the following events by searching the database 51. 1) It is determined that a side ID 126 that did not exist (or does not exist) in the database 51 newly exists. 2) It is determined that two or more identical IDs exist.

[0143] If there is a situation as described in 1) or 2) above, the management control device 50 has a function of generating an error signal indicating an abnormality and notifying the management department or the security department 54 of the game hall. Since the management control device 50 identifies all the substitute game currency 120 in the substitute game currency tray 17 for table games and the storage 62 at a predetermined timing or constantly by the side ID 126 and stores it in the database 51, 1) it can be determined that a new side ID 126 that did not exist (or does not exist) in the database 51 appears, and 2) it can also be determined that two or more identical IDs exist.

[0144] Furthermore, when there is a change in the presence of the substitute game currency 120 at least in the substitute game currency tray 17 for table games and the storage 62, the management control device 50 associates the time or location (such as the storage 62 or the substitute game currency tray 17 for table games) at which the change occurred with the side ID 126 and records it on the database 51. As a result of searching the database 51, if there is a situation where two or more identical side IDs 126 exist, the side ID 126 and the information on the time or location recorded on the database 51 associated with the side ID 126 are extracted and saved from the database 51. The time when the substitute game currency 120 with the previously detected (already used or exchanged) side ID 126 entered or exited the substitute game currency tray 17 for table games or the storage 13, or the location of the substitute game currency tray 17 for table games or the storage 13 where the substitute game currency 120 was held can be specified by the database 51. When the time and location can be specified, it becomes possible to identify a person or the like suspected of using the illegal substitute game currency 120 from the recorded video of the camera device 2.

[0145] In the management system of the substitute game currency, the management control device 50 can identify the type and number of the substitute game currency 120 bet on the bet area 8 of the game table 4 by using the ID reader 53. The substitute game currency 120 in the bet area 8 is photographed by the camera device 2b that particularly images the bet area 8, and for the side ID 126 of the substitute game currency 120 existing on the bet area 8 of the game table 4, the following events are also determined by searching the database 51. 1) The side ID 126 that did not exist in the database 51 newly exists in the bet area 16. 2) Two or more identical IDs exist. If there is a situation of the above 1) or 2), the management control device 50 has a function of generating an error signal.

[0146] The management control device 50, the ID reader 53 inside, and the substitute game currency determination device 52 that identifies the type and number of the substitute game currency 120 in this system have a structure that comprehensively includes a computer, a program, and a memory composed of an integrated or multiple configurations.

[0147] Next, the details of the substitute game currency 120 (so-called substitute game currency) used in this system will be described. FIG. 17 is a side view of the substitute game currency 120 used in this system. The substitute game currency 120 is formed by laminating a plurality of plate-shaped plastic layers of different colors and then integrating them by means such as thermocompression bonding, and then punching them into a circular or quadrilateral shape. The substitute game currency 120 manufactured in this way has at least a colored layer 121 in the middle, and white layers 122 or light-colored layers (not shown, but any layer lighter in color than the colored layer 121 is acceptable) are laminated on both sides (top and bottom in FIG. 17) of this middle colored layer 121, resulting in a multi-layer structure. By having such a colored layer 121 and laminating white layers 122 or light-colored layers (not shown, but any layer lighter in color than the colored layer 121 is acceptable) on both sides of this middle colored layer 121, a striped pattern (in the lamination direction) is formed when viewed from the side as shown in FIG. 17. By changing the color of the colored layer 121 (such as red, green, yellow, or blue) for each type of substitute game currency 120 (10 points, 20 points, 100 points, 1000 points, etc.), the type of substitute game currency 120 can be specified.

[0148] Furthermore, as shown in FIG. 17, on the side surface of the white layer 122 of the substitute game currency 120, a side ID 126 indicating the type of the substitute game currency 120 is provided. A transparent layer 124 is provided on the outermost layer, and each layer is thermocompression bonded to form at least a five-layer structure. These substitute game currencies 120 are made of an elongated plastic material. In the elongated state, the layers (at least the colored layer 121 and the white layer 122) are thermocompression bonded to form a closely adhered state (such as a five-layer structure), and then punched into a circular or rectangular shape by pressing or the like. When punching by pressing, the dimensions of the die and punch of the mold for punching are designed so that the edge of the outermost transparent layer 124 is subjected to R processing (round corners). The transparent layer 124 may be a varnish coating layer. The side ID 126 is attached to at least three locations on the side surface of the substitute game currency 120. The side ID 126 is attached by inkjet printing with ink that can be seen under visible light.

[0149] Particularly in this embodiment, the side ID 126 is composed of the presence or absence of marks C arranged in multiple rows and columns. As shown in FIG. 17, the marks C in multiple rows and columns form a code in pairs, with the upper and lower marks C, and in FIG. 17, it is a 10-digit code. FIG. 18 shows the configuration in which the upper and lower marks C form a pair to constitute codes (4 types). The Y-shaped figure horizontally across the mark C is an identification mark for distinguishing the upper and lower sides of the mark. The code composed of the marks C is configured so that a predetermined combination of the marks C can be specified. As a result, in the example shown in FIG. 18, there are 4 types as the combination of the marks C in the upper and lower two columns, and when these are printed in 10 columns, codes of 4 to the 10th power can be constituted. Since there are 4 types of 10-digit codes, codes of 4 to the 10th power types can be obtained, and thus the side ID 126 of the game substitute currency 120 can be sufficiently provided.

[0150] The gaming substitute currency 120 has a multi-layer structure in which plastic layers of a plurality of different colors are laminated, with a colored layer 121 provided in at least one layer, and a white layer 122 or a light-colored layer laminated outside the colored layer 121, so as to form a stripe pattern in the lamination direction on the side surface. The colored layer 121 enables the identification of the type of the gaming substitute currency 120. The side ID 126 is provided at at least three locations (preferably six locations) on the side surface of the white layer 122 or the light-colored layer. In this embodiment, six side IDs are provided at predetermined intervals of 60 degrees in the rotation direction (circumferential direction). The gaming substitute currency 120 is provided with individually distinguishable (different for each one) side IDs 126, which are provided at predetermined intervals of 60 degrees in the rotation direction (circumferential direction) so that the side ID 126 can always be seen from the side. The side ID 126 attached to the gaming substitute currency 120 is read by the aforementioned ID reader 53. By reading the side ID 126 with this ID reader 53, it is possible to identify the type and manufacturing information, etc. of the gaming substitute currency 120, and the side ID 126 can be managed on the database 51. In this embodiment, the side ID 126 is attached by inkjet printing with ink that can be seen with visible light. The side ID 126 may be printed with ink that is not visible with visible light (ink that absorbs infrared rays) or at least ink that is visible with visible light (including those that are very small and difficult to see), or a combination thereof. Also, the side ID 126 may be printed by combining a plurality of these types of ink. The ID reader 53 includes at least a plurality of cameras corresponding to the ink on which the side ID 126 is printed (that is, a visible light camera if the ink is visible ink, an infrared camera if the ink is infrared reactive ink, and an ultraviolet camera (UV irradiator and visible light camera) if the ink is UV ink), or a camera with multiple functions that can switch between cameras corresponding to the ink (visible light camera, infrared camera, ultraviolet camera (UV irradiator and visible light camera, etc.)).

[0151] FIG. 19 shows that in the gaming substitute currency 120-1, the side ID 126 is printed with an ink (an ink that absorbs infrared rays) that is not visible in visible light. In the gaming substitute currency 120-2, a plurality of rows and columns of marks C are printed with an ink that appears black in visible light. In the gaming substitute currency 120-3, further, marks C are printed with an ink that appears black in visible light between the side IDs 126, making the side ID 126 blend into the design and not stand out. In the gaming substitute currency 120-4, the start and end points of the side ID 126 are indicated by a mark Cf indicating the edge. When the gaming substitute currencies 120-1 to 120-4 are viewed with an infrared camera, the ink that absorbs infrared rays absorbs infrared rays and appears black, and the side ID 126 can be imaged in a readable state (shown as the gaming substitute currency 120-5). Also, the top and bottom of the side ID 126 are indicated by a mark CL indicating the top and bottom. The vertical relationship of the marks is as shown in FIG. 17. Note that the side ID 126 may be printed by a combination of an ink visible in visible light and an infrared-absorbing ink.

[0152] The side ID 126 attached to the gaming substitute currency 120 is read by the aforementioned ID reader 53, and the ID reader 53 can read the gaming substitute currency 120 held in the vault 62 held by the caster in the game hall and the gaming substitute currency tray 17 for the game table of the game table. Even when they are actually stacked horizontally (sideways) as shown in FIG. 20A, the side ID 126 can be read. Also, the gaming substitute currency 120 stacked as shown in FIG. 20B in the bet area 8 etc. can also be read.

[0153] Furthermore, the gaming substitute currency 120 is provided with a face code made of UV ink or ink that absorbs infrared rays (carbon black ink) on the surface (X) of the white layer 122 (see FIG. 9B). This face code indicates the authenticity of the gaming substitute currency 120. When ultraviolet rays (or infrared rays) are applied, the face code becomes visible to the naked eye, and the genuine one is represented by the combination of its shape and number. A transparent layer (printing layer) 124 is thermally pressed or coated on the outermost layer so as to cover the surface printing 123 (such as 100 points) for identifying the game venue and the face code on the surface. The transparent layer 124 is embossed or varnished to prevent the gaming substitute currencies 120 from sticking to each other and to improve the slipperiness. The gaming substitute currency 120 is provided with circular depressions 127 at the centers of the upper and lower surfaces. The depressions 127 can prevent the gaming substitute currencies 120 from sticking to each other and can improve the slipperiness of the gaming substitute currency 120 by increasing the diameter of the depressions 127.

[0154] The edge of the outermost transparent layer (printing layer) 124 with the printing 123 (such as 100 points) is subjected to R processing (R) to prevent the surface of the white layer 122 from being deformed and appearing on the side surface during the punching process of the gaming substitute currency 100. Also, it prevents the sharp edge of the gaming substitute currency 100 from damaging the remaining hand or other gaming substitute currencies 120. The coloring layer 121 may be formed by one or a plurality of colored layers. Furthermore, a metal or ceramic for increasing the weight may be installed in the layer of the coloring layer 121. Specifically, for example, metal powder (for example, one or a plurality of metal oxides among zinc oxide and titanium oxide) for increasing the weight may be contained in the material of the layer of the coloring layer 121. Also, a space may be provided by punching out a part of the coloring layer 121 or between the coloring layer 121 and the white layer 122, and an RFID may be built in there. In this case, the side ID 126 of the gaming substitute currency 120 is used in combination with the side ID 126 by the code with the mark C and the one by the RFID.

[0155] In the substitute game currency 120 configured in this way, the types and quantities of the substitute game currency 120 held in the substitute game currency tray 17 on the game table and the storage 62 are specified by the substitute game currency determination device 52 via the camera device 2 and the ID reading device 53, and the side ID 126 of the substitute game currency 120 existing on the substitute game currency tray 17 on the game table and the storage 62 is managed on the database 51 together with its location information. Thus, at least, 1) the situation where a side ID 126 that did not exist in the database 51 newly appears, 2) the situation where two or more identical side IDs 126 exist, are inspected. The occurrence of the situation in 1) or 2) above can be realized by searching and determining all side IDs 126.

[0156] As described above, the game participant 6 can exchange the cash 61 for substitute game currency at the cashier 60, but the exchange from the cash 61 to the substitute game currency 120 can also be performed on the game table 4. The camera device 2 images the banknotes placed on the game table 4 for exchange with the substitute game currency 120. That is, the plurality of camera devices 2 that image the substitute game currency 120 on the game table 4 are arranged at different positions and have different heights.

[0157] The management control device 50 identifies the type and number of game substitute coins 120 to be paid out from the game substitute coin tray 17 in the exchange with banknotes, using the imaging result of the banknotes by the camera device 2. The management control device 50 compares the actual total amount of the game substitute coins 120 stored in the game substitute coin tray 17 before and after the payout, and determines whether this difference corresponds to the type and number of the game substitute coins 120 to be paid out that have been identified. That is, the management control device 50 compares and determines whether the grasped total amount of the game substitute coins 120 in the game substitute coin tray 17 corresponds to the increase or decrease according to the payout amount of the game substitute coins 120 corresponding to the exchanged banknotes after the exchange of the banknotes and the game substitute coins 120 has been made. Also, when the collection and repayment according to the win / loss result of the game are performed simultaneously, the management control device 50 compares and determines whether it also corresponds to the increase or decrease of the game substitute coins 120 calculated from the amount of the game substitute coins 120 wagered by all the players 6 and the win / loss result of the game.

[0158] Here, when measuring and determining the type and number of the game substitute coins 120, the management control device 50 is a control device with an artificial intelligence utilization type or a deep learning structure capable of obtaining information on the type and number of the game substitute coins 120 even if a part or the whole of one of the game substitute coins 120 is in a hidden state.

[0159] As described above, at least three or more side IDs 126 are attached to the side white layer 122 or the light color layer of the game substitute coin 120 at intervals in the rotation direction (circumferential direction). By reading the side ID 126 with the ID reading device 53, the type and manufacturing information of the game substitute coin 120 can be identified. The information measured and identified in this way has a configuration that can be collated and managed with the database 51.

[0160] The management control device 50 may be a control device having an artificial intelligence utilization type or a deep learning structure. The management control device 50 uses an artificial intelligence utilization type computer or control system, deep learning (structure) technology, self-learning function, etc., to grasp the position 8 (the position bet on by the player, banker, or pair), type (the game substitute currency has different values assigned for each color), and number of the game substitute currency 120.

[0161] A modification example of the game substitute currency 120 will be described below. In the modification example, a 7-digit number is printed as the side ID 126 on the side surface of the game substitute currency 120. In the embodiment shown in FIG. 21, a white layer 122 is provided at the center, and colored layers 121 are provided above and below it. A number as a mark is printed on the central white layer 122 to form the side ID 126. As 10 combinations of numbers, when these are printed in digits, 10 to the 7th power of codes can be formed, so that the side ID 126 of the game substitute currency 120 can be sufficiently provided. In the camera device 2 and its image analysis, it may be difficult to determine and read the numbers, and the combination of marks C in the previously shown embodiment is considered advantageous in terms of image analysis.

[0162] Another inspection device 300 for inspecting the game substitute currency 120 will be described with reference to FIG. 22. It includes a face code reading device 306 that reads the face code M formed by UV-emitting ink or ink that absorbs infrared rays provided on the surface of the game substitute currency 120, an ID reading device 307 that reads the side ID 126 on the side surface, an RFID reading device 308 that reads the information of the RFID (not shown) of the game substitute currency 120, and a control device 207. The control device 207 is configured to inspect the correlation between the information of the side ID 126 obtained by the ID reading device 307, the information obtained from the face code reading device 306, and the information obtained from the RFID reading device 308. The correlation of the above information is inspected by comparing the reading result with a correct database (not shown). This inspection is used to detect printing errors of the face code M and the side ID 126 to prevent the occurrence of defects or to distinguish from counterfeits.

[0163] This embodiment (Fig. 22) includes an extrusion device 302 that supplies the gaming substitute coins 120 one by one to the reading stage 309 by an extrusion part 301 that moves in the Z arrow direction by the extrusion device 302. The stacked gaming substitute coins 120 are supplied from the extrusion device 302 to the reading stage 309. Thereby, the gaming substitute coins 120 before the inspection is completed are pushed out and fall in the X arrow direction, and the gaming substitute coins 120 that have fallen in the X arrow direction are held by the holding stage 310.

[0164] Another inspection device 400 for inspecting the gaming substitute coins 120 will be described with reference to Fig. 23. The inspection device 400 includes an RFID reader 408 that reads the information of the RFID (not shown) of the gaming substitute coin 120, an ID reader 307 that reads the side ID 126 on the side, and a control device 207, and is configured to inspect the correlation between the information of the side ID 126 obtained by the ID reader 307 and the information obtained from the RFID reader 408. The correlation of the above information is inspected by comparing the reading result with a correct database (not shown). This inspection is used to detect printing errors of the face code M and the side ID 126 to prevent the occurrence of defects or to distinguish from counterfeits.

[0165] The ID reader 307 is configured to include a visible light camera or an infrared camera corresponding to the ink on which the side ID 126 is printed, and a camera 409 that can switch between a plurality of functions of a visible light camera and an infrared camera corresponding to the printed ink. The visible light camera can read the number and color of the gaming substitute coins 120, and the infrared camera can read the side ID 126 of the gaming substitute coins 120.

[0166] Another inspection device 450 for inspecting the gaming substitute currency 120 will be described with reference to FIG. 24. The same parts as those of the inspection device 400 are given the same numbers (description omitted). The ID reader 307 is configured to include a plurality of visible light cameras 304 or infrared cameras 305 corresponding to the ink printed on the side ID 126. The visible light camera 304 can read the number and color of the gaming substitute currency 120, and the infrared camera 305 can read the side ID 126 of the gaming substitute currency 120.

[0167] The management control device 50 obtains the total amount of the gaming substitute currency (chips) in the gaming substitute currency tray 17 after the settlement at the end of the game via the gaming substitute currency determination device 52. In this case, the determination after the settlement is assumed to occur when any one of the following 1) to 4) occurs. 1) When the repayment for the winning gaming substitute currency (winning chips) 120 is completed, 2) When the card C used in the game is collected and discarded in the discard area or discard slot of the table, 3) When a predetermined button attached to the card distribution device 3 functioning as a win / loss result determination device is pressed, 4) When the marker 43 indicating the win / loss is returned to its original position.

[0168] In addition, in the present embodiment, the progress state of the game played on the game table 4 in the second embodiment is recorded as an image via a plurality of camera devices 2 including the game participants 6 and the dealer 5, and the image of the recorded game progress state is analyzed. By doing so, an image analysis device 18 capable of analyzing and grasping the total amount of the game substitute currency 120 in the game substitute currency tray 17 of the dealer 5 on the game table 4, a measuring device 19 that analyzes and measures using the information obtained by the image analysis device 18 to determine the type and number of the game substitute currency 120, and / or a mark reading device 205 that reads the face code using UV-emitting ink or ink that absorbs infrared rays provided on the surface of the game substitute currency 120 are combined. Furthermore, if necessary, an RFID reading device 308 that reads the information of the RFID 125 of the game substitute currency 120 is combined, thereby configuring the following inspection device including the management control device 50.

[0169] That is, by combining the RFID reading device 308 that reads the information of the RFID 125 of the game substitute currency 120 with the above configuration, an inspection device including an ID reading device 53 that reads the side ID 126 on the side and the management control device 50 can be configured. In this inspection device, the management control device 50 inspects the relationship between the information of the side ID 126 read by the ID reading device 53 and the information of the RFID 125 read by the RFID reading device 308.

[0170] Also, by combining the mark reading device 205 of the second embodiment that reads the face code using UV-emitting ink or infrared-absorbing ink provided on the upper or lower surface of the game substitute currency 120 with the above configuration, an inspection device including an ID reading device 53 that reads the side ID 126 on the side and the management control device 50 can be configured. In this inspection device, the management control device 50 inspects the relationship between the information of the side ID 126 read by the ID reading device 53 and the information of the face code read by the mark reading device 205.

[0171] Further, by combining the above-described configuration with a mark reader 205 of the second embodiment that reads a face code using UV-emitting ink or infrared-absorbing ink provided on the surface of the gaming substitute currency 120, and an RFID reader 308 that reads the information of the RFID 125 of the gaming substitute currency 120, an inspection device including an ID reader 53 that reads the side ID 126 on the side surface and a management control device 50 can be configured. In this inspection device, the management control device 50 inspects the correlation among the information of the side ID 126 read by the ID reader 53, the information of the face code read by the mark reader 205, and the information of the RFID 125 read by the RFID reader 308.

[0172] As described above, in the present embodiment, the gaming substitute currency 120 has a side ID 126 for identifying each individual attached to the outer surface of the white layer 122 or the light-colored layer.

[0173] This side ID 126 is attached at least at three or more locations at intervals in the circumferential direction (circumferential direction) on the side surface of the gaming substitute currency 120.

[0174] Further, the side ID 126 is printed with an invisible ink (for example, infrared-absorbing ink or UV-emitting ink) that cannot be seen with visible light.

[0175] Furthermore, a plurality of rows of the side ID 126 are provided on each of the side surfaces of the two layers of the white layer 122 or the light-colored layer.

[0176] Further, at least one of the plurality of plastic layers constituting the colored layer 121 and the white layer 122 is a layer containing a metal powder for increasing weight (for example, one or more metal oxides among zinc oxide and titanium oxide) in the layer.

[0177] Further, the side ID 126 may be printed with two or more inks including at least an ink visible in visible light, an infrared absorbing ink, or a UV ink. In this case, the ID reader 53 includes a plurality of cameras corresponding to each ink used for printing the side ID 126, or includes a camera capable of switching a plurality of imaging functions corresponding to each ink.

[0178] Also, the gaming substitute currency 120 is manufactured as follows. First, a colored layer 121 and a white layer 122 or a light-colored layer sandwiching the colored layer 121 are heat-pressed to form a laminated structure including a plurality of plastic layers. Then, a pattern is printed on at least the upper surface or the lower surface of the laminated structure to create a substitute currency plate. Then, the substitute currency plate is punched by a die to obtain a plurality of gaming substitute currencies having a predetermined shape. Here, at least one layer of the plurality of plastic layers uses a layer containing a metal powder or a metal oxide for weight increase. A side ID 126 for identifying each individual is printed on the side surface of the gaming substitute currency 120 manufactured in this way. At this time, the side ID 126 may be printed by inkjet printing.

[0179] Also, an RFID 125 is sandwiched between the layers of the laminated structure, and when heat-pressing each layer, the layers sandwiching the RFID 125 are heat-welded to closely adhere and fix the periphery of the RFID 125 with a plastic layer.

[0180] Further, the management system for the table game of the present embodiment is provided on the gaming table 4, and includes a gaming substitute currency tray 17 that holds the gaming substitute currency 120 for each type thereof, a camera device 2 that images the gaming substitute currency 120 held in the gaming substitute currency tray 17, and uses the imaging result by the camera device 2 to identify the type and number of the gaming substitute currency 120 held in the gaming substitute currency tray 17, and a management control device 50 that measures the total amount of the gaming substitute currency 120 on the gaming substitute currency tray 17.

[0181] The gaming substitute currency 120 is a laminated structure in which a colored layer 121 and a white layer 122 or a light-colored layer are laminated, and has a stripe pattern in the lamination direction on the side surface. The management control device 50 has a function of measuring the number of the colored layer 121 or the white layer 122 or the light-colored layer of the gaming substitute currency placed by each game participant, and determining the type and amount of the gaming substitute currency based on the color of the colored layer 121.

[0182] The management control device 50 determines whether the actual total amount of the gaming substitute currency 120 in the gaming substitute currency tray 17 after the grasped game ends corresponds to the increase or decrease amount of the gaming substitute currency 120 calculated from the amount of the gaming substitute currency 120 wagered by all players 6 and the win / loss result of the game.

[0183] The management control device 50 obtains the total amount of the gaming substitute currency 120 in the gaming substitute currency tray 17 after the settlement at the end of the game when 1) when the repayment for the winning gaming substitute currency 120W is completed, 2) when the card used in the game is collected and discarded in the discard area of the table, 3) when a predetermined button attached to the card distribution device 3 functioning as a win / loss result determination device is pressed, 4) when the marker indicating the win / loss is reset, whichever of the above is the case.

[0184] The camera device 2 can also image the banknotes placed on the gaming table 4 for exchange with the gaming substitute currency 120. The management control device 50 uses the imaging result of the banknotes to specify the type and number of the gaming substitute currency 120 on the gaming substitute currency tray 17 that should be reduced by the exchange of the gaming substitute currency 120 on the gaming substitute currency tray 17 and the banknotes, and compares it with the actual total amount of the gaming substitute currency 120 on the gaming substitute currency tray 17.

[0185] The management control device 50 compares and determines whether the total amount of the game substitute currency 120 grasped in the game substitute currency tray 17 corresponds to the increase or decrease according to the payment amount of the game substitute currency 120 corresponding to the exchanged banknotes after the exchange between the banknotes and the game substitute currency 120, and the increase or decrease of the game substitute currency 120 calculated from the amount of the game substitute currency 120 wagered by all the players 6 and the win / loss result of the game.

[0186] When measuring and determining the type and number of the game substitute currency 120, the management control device 50 is a control device with an artificial intelligence utilization type or a deep learning structure capable of obtaining information on the type and number of the game substitute currency 120 even when a part or the whole of one piece of the game substitute currency 120 is in a hidden state.

[0187] The game substitute currency 120 is provided with side IDs 126 at least at three or more positions at intervals in the rotation direction (circumferential direction) on the white layer 122 or the light-colored layer on the side surface. By reading the side ID 126 with the ID reader 53, the type and manufacturing information of the game substitute currency 120 can be specified, and the measured and specified information has a configuration that can be collated and managed with the database 51.

[0188] The side ID 126 may be printed with two or more of visible ink (visible ink), infrared absorption ink, or UV emission ink that can be seen with visible light. In this case, the ID reader 53 is provided with a plurality of types of cameras (a plurality of types among visible light cameras, infrared cameras, ultraviolet cameras (UV irradiators and visible light cameras, etc.)) corresponding to the ink on which the side ID 126 is printed. Alternatively, a camera capable of switching a plurality of imaging functions of a visible light camera, an infrared camera, and an ultraviolet camera (UV irradiator and visible light camera, etc.) may be provided corresponding to each ink.

[0189] Also, it may be configured to image the game substitute currency 120 on the game table 4 with a plurality of camera devices 2b-1 and 2b-2 that are respectively arranged at predetermined positions and have different heights.

[0190] In the above-described embodiment, the image analysis device 12 and the control device 14 are devices having an artificial intelligence utilization type or a deep learning structure. Specifically, the image analysis device 12 and the control device 14 may perform image analysis and various controls described above using, for example, a Scale-Invariant Feature Transform (SIFT) algorithm, a Convolutional Neutral Network (CNN), deep learning, machine learning, or the like. These technologies are technologies for performing image recognition on a captured image to recognize an object included in the image. In particular, in recent years, high-precision object recognition has been performed using deep learning technology that multiplies the number of layers of a neural network. This deep learning technology generally recognizes an object with high precision by stacking layers in multiple stages in an intermediate layer between the input layer and the output layer of the neural network. In this deep learning technology, in particular, the convolutional neural network has attracted attention because it has higher performance than recognizing an object based on conventional image feature amounts.

[0191] In a convolutional neural network, a recognition target image with a label is learned, and the main object included in the recognition target image is recognized. When there are a plurality of main objects in the learning image, they are specified by a region rectangle, and learning is performed by attaching a label to the image corresponding to the specified region. Further, in a convolutional neural network, it is also possible to determine the main object in the image and the position of the object.

[0192] To further explain the convolutional neural network, in the recognition process of the target, candidate regions are extracted based on local features by performing edge extraction processing or the like on the recognition target image, and after extracting the feature vectors by inputting the candidate regions into the convolutional neural network, classification is performed, and the candidate region with the highest confidence level obtained by the classification is obtained as the recognition result. The confidence level is a quantity indicating to what extent the similarity of the main body of the image learned together with a certain image region and a label is relatively higher than the similarity of other classes.

[0193] Regarding devices having an artificial intelligence utilization type or a deep learning structure, they are described in U.S. Patent No. 9,361,577, U.S. Patent Publication No. 2016-171336, U.S. Publication No. 2015-036920, Japanese Patent Publication No. 2016-110232, etc., and these descriptions are incorporated herein by reference.

[0194] (Fourth Embodiment) When the game ends, the dealer recovers the game substitute currency bet by the player and pays out the game substitute currency to the player according to the game result and the bet content (bet target and bet amount) of each player. Whether this recovery and payout (hereinafter, the recovery and payout are collectively referred to as "settlement") is performed accurately is preferably checked at the time when the settlement is performed, and can be clearly confirmed by the player and the dealer.

[0195] Therefore, in the present embodiment, a system for displaying the accuracy of settlement at the time of settlement of game substitute currency after the game ends is provided.

[0196] FIG. 25 is a plan view of the game table of the present embodiment. FIG. 26 is a plan view of the game substitute currency tray of the present embodiment. FIG. 27 is a diagram showing the overall configuration of a management system for game substitute currency including the game substitute currency tray. In FIGS. 25 to 29, the same components as those in the first to third embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

[0197] The gaming table 4 is a baccarat table, and betting areas 44 for each of seven players are provided. Each player's betting area 44 includes areas for PLAYER 441, BANKER 442, TIE 443, PLAYER PAIR (P) 444, and BANKER PAIR (B) 445. Each player places a bet by placing gaming tokens equivalent to the amount to be bet at a position corresponding to the object of the bet. The gaming table 4 is further provided with a player card area 45 for placing the drawn player cards and a banker card area 46 for placing the drawn banker cards.

[0198] In front of the dealer position of the gaming table 4, a gaming token tray 17 for the dealer to store the gaming tokens is provided. At least a part of the gaming token tray 17 is embedded in the gaming table 4.

[0199] The configuration of the gaming tokens 120 used in the present embodiment has the same configuration as that of the first to third embodiments. That is, the gaming tokens 120 have notations, patterns, or colors that can identify their types (values) from their surfaces and sides, respectively. Further, the gaming tokens 120 have an RFID embedded therein that stores information capable of identifying at least their types.

[0200] The camera device 2 is provided above the gaming table 4 and photographs the betting area 44. The gaming table 4 of the present embodiment is provided with seven player positions ( "1", "2", "3", "5", "6", "7", "8" in FIG. 25), and seven players can participate in the game. The camera device 2 photographs the betting areas 44 of all the player positions. Note that it is not necessary for one camera device 2 to photograph the betting areas 44 of all the player positions, and a plurality of camera devices 2 may be used to photograph all the betting areas 44 in a shared manner.

[0201] The management control device 50 has all the functions described in the first to third embodiments. The management control device 50 specifies the position (bet target), type, and number of gaming substitute coins placed in the bet area based on the image captured by the camera device 2. The device composed of this camera device 2 and the management control device 50 functions as a measuring device or a bet determination device for measuring the position, type, and number of gaming substitute coins on the gaming table 4, and its configuration and functions are the same as those of the system composed of the camera device 2 and the image analysis device 12 in the first embodiment.

[0202] The card distribution device 3 also has the same configuration and functions as in the first embodiment. That is, the card distribution device 3 determines the winning or losing result of the game on the gaming table 4 and displays it on the result display lamp. Also, the card distribution device 3 sends the determined winning or losing result of the game to the management control device 50. The management control device 50 grasps the position, type, and number of gaming substitute coins on the gaming table 4, and has a function of performing a casino-side revenue and expenditure calculation on the gaming table 4 using the winning or losing result obtained from the card distribution device 3 as a winning or losing determination device.

[0203] Based on the bet content determined based on the image of the camera device 2 and the information on the winning or losing result obtained from the card distribution device 3, the management control device 50 grasps, by calculation, the amount of gaming substitute coins on the gaming table 4 that the casino side should collect and the amount of gaming substitute coins that the casino side should pay out in the game, and compares each with the amount of gaming substitute coins that actually increased in the gaming substitute coin tray 17 by collection and the amount of gaming substitute coins that actually decreased in the gaming substitute coin tray 17 by payout.

[0204] Also, the management control device 50 reads the RFID of the gaming substitute coins 120 stored in the gaming substitute coin tray 17 at a predetermined time interval and stores the information read when a change occurs. Based on the stored information, the management control device 50 compares the type and number of gaming substitute coins at a past time point with the type and number of gaming substitute coins at the current time point, and calculates the increase or decrease amount of the gaming substitute coins 120 in the gaming substitute coin tray 17.

[0205] As shown in FIG. 26, the game token tray 17 includes a storage unit 170 and display lamps 173 to 176. The storage unit 170 is composed of a plurality of columns, and each column is configured to be able to stack and store game tokens in the thickness direction. As shown in FIG. 27, an antenna 177 is disposed below the storage unit 170.

[0206] The display lamp 173 indicates whether the balance of the collected amount and the paid-out amount is correct. The display lamp 174 respectively indicates whether the total amount of the collected amount is correct and whether the total amount of the paid-out amount is correct. The display lamp 175 indicates whether the collected amount or the paid-out amount for the game tokens bet in pairs is correct.

[0207] The display lamp 176 has a total of seven display lamps corresponding to seven player positions. In the collection stage, the display lamp 177 lights up the display lamp corresponding to the player from whom the game tokens should be collected (the player who lost the game), and in the payout stage, the display lamp corresponding to the player to whom the game tokens should be paid out (the player who won the game) lights up. In FIG. 27, only the display lamp 173 is illustrated as a representative of the display lamps 173 to 176, and the illustration of the other display lamps 174 to 176 is omitted.

[0208] The management control device 50 controls the lighting and extinguishing of the display lamps 173 to 176 to display the result (match or mismatch) of the above comparison. The game token management system of the present embodiment grasps in real time whether the settlement of game tokens is correctly performed by using the display lamps 173 to 176. The game token management system of the present embodiment also grasps in real time whether the collected game tokens contain any illegal game tokens.

[0209] First, the management control device 50 identifies the players participating in the game on the gaming table 4 and associates the participating players with the player position numbers of the gaming table 4 (「1」, 「2」, 「3」, 「5」, 「6」, 「7」, 「8」). Specifically, the management control device 50 can identify the players in each player position using, for example, a face recognition system or a members card.

[0210] When the game ends, the management control device 50 determines, for each player, the gaming substitute currency (casino-side winning chips) that the dealer should collect based on the game result, and lights up the display lamp 176 corresponding to the player position where the collection should be made. As a result, the dealer can grasp which player position's gaming substitute currency should be collected.

[0211] When the game ends, the dealer first collects all the gaming substitute currency that should be collected from the bet areas of the losing players (collection stage), and then pays out to the winning players (payout stage). In the collection stage, the dealer stores the gaming substitute currency collected from the bet area 41 of the gaming table 4 in the storage section 170 of the gaming substitute currency tray 17 according to the display lamp 176. Specifically, the dealer stores the collected gaming substitute currency in either of the two right columns, which are the collection sections, in ascending order of the player position numbers.

[0212] Each time the dealer collects the gaming substitute currency from the bet area 41 and stores it in the collection section of the storage section 170, the management control device 50 determines, based on the image from the camera device 2, that the gaming substitute currency has been collected from the bet area 44 and the amount thereof, and determines, based on the radio wave received by the antenna 177, the amount (increase amount) of the gaming substitute currency stored in the collection section. In the present embodiment, two of the 14 columns are used as the collection section for the storage section 170, but the collection section for storing the collected gaming substitute currency may be, for example, the horizontal gaming substitute currency collection tray 171 shown in FIG. 13A, or, as shown in FIG. 13B, a gaming substitute currency collection tray 171 provided separately from the other columns.

[0213] Here, the management control device 50 obtains the increase amount for each player by using RFID to determine the difference in the total amount of game substitute currency in the storage unit 170 before and after collection. In this way, the management control device 50 that reads the information on the type (value) from the RFID of the game substitute currency held in the storage unit 170 and determines the amount of game substitute currency held in the storage unit 170 corresponds to the dealer chip determination device of the present invention.

[0214] The management control device 50 further determines whether the actual collection amount (image collection amount) determined based on the image from the camera device 2, the increase amount of game substitute currency (RFID collection amount) in the collection unit determined based on the radio wave received by the antenna 177, and the collection amount (calculated collection amount) calculated based on the game result and the bet content of the losing player match.

[0215] When the image collection amount, the RFID collection amount, and the calculated collection amount all match, the management control device 50 turns off the corresponding display lamp 176. By confirming the turning off of the display lamp 176, the dealer can confirm that the collection of game substitute currency from the player has been accurately completed.

[0216] On the other hand, when the image collection amount, the RFID collection amount, and the calculated collection amount do not match, the display lamp 176 remains lit. Thus, the dealer can know whether the collection from the corresponding player has not been accurately completed or whether there is counterfeit game substitute currency among the collected game substitute currency.

[0217] When the collection of game substitute currency as described above is completed for all losing players, all the display lamps 176 will go out. At this point, the management control device 50 determines the total increase amount to the collection unit again by RFID, and compares it with the calculated total collection amount calculated based on the game result and the bet content of all losing players. If they match, the display lamp 174 is lit.

[0218] Here, the management control device 50 obtains the total RFID recovery amount by determining the difference between the total amount of gaming substitute currency in the storage unit 170 obtained by RFID after the game ends and before the start of the recovery stage, and the total amount of gaming substitute currency in the storage unit 170 obtained by RFID after the recovery is completed. The dealer can confirm that the lighting of the display lamp 174 indicates that the recovery of the gaming substitute currency has been accurately completed.

[0219] In the above description, the management control device 50 determines whether the image recovery amount determined based on the image from the camera device 2, the RFID recovery amount determined based on the radio wave received by the antenna 177, and the calculated recovery amount calculated based on the game result and the bet content of the losing player all match. Instead of this, the management control device 50 may only determine whether the image recovery amount and the calculated recovery amount match, or may only determine whether the RFID recovery amount and the calculated recovery amount match.

[0220] Also, in the above description, when the management control device 50 determines that the recovery has been completed for all losing players, it determines the total increase amount again by RFID and lights the display lamp 174 when it matches the calculated total recovery amount. Instead of this, the following method may also be used. That is, as described above, the management control device 50 stores the RFID information read each time there is a change in the gaming substitute currency 120 in the gaming substitute currency tray 17. At the same time, each time there is a change in the gaming substitute currency 120 in the gaming substitute currency tray 17, it determines the total increase amount and determines whether it matches the calculated total recovery amount, and lights the display lamp 174 when it determines that they match.

[0221] Next, the dealer makes a payout to the winning player (payout stage). When the collection from all losing players is completed, the management control device 50 lights up the display lamp 176 corresponding to the player to whom game substitute currency is to be paid out. By checking the display lamp 176, the dealer can identify the player to whom the payout should be made. In the payout stage, the dealer takes out the game substitute currency of the payout amount from the storage unit 170 and places the taken-out game substitute currency in the bet area of the corresponding player, thereby making the payout.

[0222] Each time the dealer takes out game substitute currency from the storage unit 170 and places it on the game table 4, the management control device 50 determines, based on the image from the camera device 2, that game substitute currency has been paid out to the bet area and the amount thereof, and determines, based on the radio wave received by the antenna 177, the amount (decrease amount) of the game substitute currency taken out from the storage unit 170. Here, the management control device 50 obtains the decrease amount for each player by using RFID to find the difference in the total amount of game substitute currency in the storage unit 170 before and after the payout.

[0223] The management control device 50 further determines whether the actual payout amount (image payout amount) determined based on the image from the camera device 2, the decrease amount of the game substitute currency in the storage unit 170 (RFID payout amount) determined based on the radio wave received by the antenna 177, and the payout amount (calculated payout amount) of the winning player calculated based on the game result and the bet content match.

[0224] When the image payout amount, the RFID payout amount, and the calculated payout amount all match, the management control device 50 turns off the corresponding display lamp 176. By checking the extinguishing of the display lamp 176, the dealer can confirm that the payout of the game substitute currency to that player has been accurately completed.

[0225] On the other hand, when the image payout amount, the RFID payout amount, and the calculated payout amount do not match, the display lamp 176 remains lit, so the dealer can know that the payout to the corresponding player has not been completed.

[0226] When the payout of game substitute currency is completed for all winning players, all the display lamps 176 will go out. At this point, the management control device 50 determines the total reduction amount in the storage unit 170 again by RFID, and compares it with the calculated payout total amount calculated based on the total reduction amount, the game result, and the bet content. If they match, the display lamp 174 is lit.

[0227] Here, the management control device 50 obtains the RFID payout total amount by finding the difference between the total amount of game substitute currency in the storage unit 170 obtained by RFID after the completion of collection and before the start of the payout stage, and the total amount of game substitute currency in the storage unit 170 obtained by RFID after the completion of the payout. The dealer can confirm that the display lamp 174 is lit and thus can grasp that the payout of game substitute currency has been completed accurately.

[0228] In the above, the management control device 50 determines whether the image payout amount determined based on the image from the camera device 2, the RFID payout amount determined based on the radio wave received by the antenna 177, and the calculated payout amount calculated based on the game result and the bet content of the winning player all match. Instead of this, the management control device 50 may only determine whether the image payout amount and the calculated payout amount match, or may only determine whether the RFID payout amount and the calculated payout amount match.

[0229] Also, in the above, when the management control device 50 determines that the payout has been completed for all winning players, it determines the total reduction amount again by RFID and lights the display lamp 174 when it matches the calculated payout total amount. Instead of this, the following method may also be used. That is, as described above, the management control device 50 stores the RFID information read each time there is a change in the game substitute currency 120 in the game substitute currency tray 17. At the same time, each time there is a change in the game substitute currency 120 in the game substitute currency tray 17, it determines the total reduction amount and judges whether it matches the calculated payout total amount. When it is determined that they match, the display lamp 174 may be lit.

[0230] As described above, when the settlement (collection and payout) of the game substitute currency is completed, the management control device 50 determines whether the total increase or decrease in the game substitute currency in the storage unit 170 due to the settlement is correct. Specifically, the management control device 50 obtains the total increase or decrease amount (RIFD total increase or decrease amount) due to the settlement by obtaining the difference between the total amount of the game substitute currency in the storage unit 170 obtained by RFID before the settlement starts after the game ends and the total amount of the game substitute currency in the storage unit 170 obtained by RFID after the settlement ends.

[0231] On the other hand, the management control device 50 calculates the total increase or decrease amount of the dealer due to the settlement of the game (calculated total increase or decrease amount) based on the game result and the bet content. The calculated total increase or decrease amount can be obtained by subtracting the calculated payout total amount from the calculated collection amount. The management control device 50 compares the RFID total increase or decrease amount with the calculated total increase or decrease amount, and if they match, turns on the display lamp 171. The dealer can confirm that the settlement of the game substitute currency in the game has been accurately completed by confirming that the display lamp 171 is lit, and can then start the next game.

[0232] Next, the display lamp 175 will be described. The display lamp 175 functions as a pair lamp. In the baccarat game, in addition to "Player", "Banker", and "Tie", the player can also bet on "Pair". "Pair" is a bet on the ranks of the first two cards dealt being the same. Specifically, "Pair" includes "Player Pair", which bets on the ranks of the two player cards being the same, and "Banker Pair", which bets on the ranks of the two banker cards being the same.

[0233] If any player bets on a pair and the ranks of the two cards match (a pair is formed), regardless of the game result ("Player", "Banker", or "Tie"), the player who bet on the pair will receive a payout of a predetermined multiple (e.g., 11 times) of the bet amount. If the pair is not formed, all the gaming tokens bet on the pair will be collected. When the first 4 cards (2 for the player and 2 for the banker) are drawn, if no pair is formed, the gaming tokens bet on the pair at that time will be collected.

[0234] When betting on a pair, the management control device 50 calculates the total collection amount (when the pair is not formed) or the total payout amount (when the pair is formed) when 4 cards are drawn, and compares it with the total increase or decrease in the gaming tokens in the storage unit 170 obtained using RFID before and after the settlement of the pair. Note that the management control device 50 can recognize whether a bet on a pair is made and the amount thereof based on the image of the camera device 2.

[0235] When the total collection amount or the total payout amount calculated by the management control device 50 matches the total increase or decrease in the gaming tokens in the storage unit 170, the display lamp 175 is lit. By confirming the lighting of the display lamp 175, the dealer can confirm that the settlement of the pair is completed accurately.

[0236] Alternatively, instead of the above, the management control device 50 may light the display lamp 175 when a bet on a pair is made. The timing of lighting the display lamp 175 may be when the bet is closed or when 4 cards are drawn. In this case, by confirming that the display lamp 175 is lit, the dealer can recognize that the settlement of the pair needs to be performed.

[0237] Also, in this case, when the total collection amount or the total payout amount calculated by the management control device 50 matches the total increase or decrease in the gaming tokens in the storage unit 170, the display lamp 175 is turned off. By confirming the extinguishing of the display lamp 175, the dealer can confirm that the settlement of the pair is completed accurately.

[0238] In Baccarat, the game may end with 4 draws (2 player cards and 2 banker cards) depending on the rank of the cards dealt, or there may be a 5th or subsequent 6th draw. When the game ends with 4 draws, once the pair settlement is completed, the normal settlement described above is entered. When drawing the 5th card or later, after drawing the 4th card, the pair settlement is performed. Once the pair settlement is complete, the 5th card (or subsequent 6th card) is drawn. When the game ends, the normal settlement described above is performed.

[0239] In the above embodiment, in the collection stage, the display lamp 176 of the losing player from whom the game substitute currency should be collected is lit, and the display lamp 176 is turned off in order from the player for whom the collection has been completed. Also, in the payout stage, the display lamp 176 of the winning player to whom the game substitute currency should be paid out is lit, and the display lamp 176 is turned off in order from the player for whom the payout has been completed. Instead of this, at the end of the game, all the display lamps 176 may be lit with different colors for the winning players and the losing players.

[0240] For example, the display lamp 176 corresponding to the losing player may be lit in red, and the display lamp 176 corresponding to the winning player may be lit in green. In this case, by confirming that all the red display lamps 176 have been turned off, it can be confirmed that the collection from all the losing players has been accurately completed. By confirming that all the green display lamps 176 have been turned off, it can be confirmed that the payout to all the winning players has been accurately completed.

[0241] FIG. 28 is a plan view of a game substitute currency tray according to a modified example. In the game substitute currency tray 17 of FIG. 28, the same components as those of the game substitute currency tray 17 in FIG. 26 are denoted by the same reference numerals, and the description thereof will be omitted as appropriate. In the game substitute currency tray 17 of this modified example, display lamps 1761 to 1765 for each betting target (specifically, a display lamp 1761 indicating "Player", a display lamp 1762 indicating "Banker", a display lamp 1763 indicating "Tie", a display lamp 1764 indicating "Player Pair", and a display lamp 1745 indicating "Banker Pair"), and a display lamp 178 indicating that the settlement has been completed accurately are provided for each player position.

[0242] The display lamps 1761 to 1765 are lit corresponding to the betting target (the position where the game substitute currency is placed) of the player, and are turned off when the settlement is completed. The display lamp 178 is lit when the settlement is completed accurately for each player.

[0243] The game substitute currency 17 of this modified example further includes display lamps 1741 to 1745 indicating that the settlement has been completed accurately for each betting target ("Player", "Banker", "Tie", "Player Pair", "Banker Pair"). Depending on the winning or losing result of the game, one of "Player", "Banker", and "Tie" is paid out, and the rest are collected. Also, when a player pair is formed, "Player Pair" is paid out, and when a player pair is not formed, "Player Pair" is collected. Similarly, when a banker pair is formed, "Banker Pair" is paid out, and when a banker pair is not formed, "Banker Pair" is collected. The display lamps 1741 to 1745 are lit when the settlement (collection or payout) has been completed accurately for each of "Player", "Banker", "Tie", "Player Pair", and "Banker Pair".

[0244] FIG. 29 is a plan view of a game substitute currency tray 17 according to another modified example. As in the example of FIG. 29, the game substitute currency tray 17 may be provided with only a display lamp 173 for displaying whether the balance of the collected amount and the paid-out amount is correct.

[0245] FIG. 30 is a plan view of the game substitute currency 17 of still another modified example. As shown in FIG. 30, the game substitute currency tray 17 may be provided with only a display lamp 173 for displaying whether the balance between the collected amount and the paid-out amount is correct, and display lamps 174 for respectively displaying whether the total amount of the collected amount is correct and whether the total amount of the paid-out amount is correct.

[0246] In the above-described embodiments and their modified examples, the management control device 50 determines the amount of the game substitute currency stored in the game substitute currency tray 17 by wirelessly reading the RFID incorporated in the game substitute currency and the antenna 177 incorporated under the game substitute currency tray 17. Instead of this, a camera device for photographing the game substitute currency stored in the game substitute currency tray 17 may be provided, and the amount of the game substitute currency stored in the game substitute currency tray 17 may be determined by performing image recognition on the image of this camera device. In this case, the game substitute currency may not incorporate an RFID.

[0247] In the above-described embodiment, an example in which a plurality of display lamps including the display lamp 173 are configured as physically existing lamps has been described, but these lamps may be configured as images in a display device such as a liquid crystal panel.

[0248] In the above-described embodiment, the information on the type and number of the game substitute currency 120 stored in the game substitute currency tray 17 is determined by reading the RFID incorporated in the game substitute currency 120. Instead of this, or in addition to this, a camera device for photographing the game substitute currency 120 stored in the game substitute currency tray 17 may be provided, and the information on the type and number of the game substitute currency 120 stored in the game substitute currency tray 17 may be determined by image recognition in the management control device 50. In this case, the camera device for photographing the game substitute currency tray 17 may be shared with the above-described camera device 2, or a dedicated camera device may be provided.

[0249] Also, when performing image recognition on the images of the camera device in addition to reading the RFID, the number of gaming tokens 120 obtained by reading the RFID may be compared with the number of gaming tokens determined by image recognition to verify the gaming tokens 120. If a gaming token tray 17 contains a gaming token with a damaged RFID or no RFID (illegal gaming token), the number determined by image recognition will be greater than the number determined by reading the RFID. Therefore, when such a discrepancy occurs, the management control device 50 lights up the display lamp, and the dealer can recognize through the display lamp that the gaming token tray 17 contains illegal gaming tokens.

[0250] In particular, by performing RFID reading and image recognition at predetermined time intervals and conducting the above comparison each time the information is updated, when a discrepancy in the number occurs, it can be determined that the discrepancy is due to the gaming tokens 120 newly added to the gaming token tray 17 most recently. Thus, it becomes possible to identify the player who had the illegal gaming tokens.

[0251] Further, the management control device 50 may verify that no corresponding gaming tokens exist on the gaming table as a result of the dealer collecting the gaming tokens from the gaming table. In this case, specifically, the management control device 50 determines, based on the image from the camera device 2, which types of gaming tokens and how many are bet on which bet targets. Further, based on the game result in the card distribution device 3, it determines the amount to be collected according to the game rules (calculated collection amount), and verifies, based on the image from the camera device 2, that the gaming tokens 120 corresponding to the calculated collection amount no longer exist on the gaming table 4.

[0252] Furthermore, the management control device 50 may compare the amount of gaming substitute currency that has disappeared from the gaming table 4 (image collection amount) based on the image from the above-described camera device 2 with the amount of gaming substitute currency added to the gaming substitute currency tray 17, and verify whether the collection has been accurately performed. In this case, if the two do not match as a result of the comparison, the management control device 50 may turn on the display lamp.

[0253] In addition, the management control device 50 may verify that corresponding gaming substitute currency exists on the gaming table as a result of the dealer paying out the gaming substitute currency to the gaming table. In this case, specifically, the management control device 50 determines which type of gaming substitute currency and how many are bet on which betting target based on the image from the camera device 2, and further determines the amount to be paid out (calculated payout amount) according to the game rules based on the game result in the card distribution device 3, and verifies based on the image from the camera device 2 that gaming substitute currency 120 corresponding to the calculated payout amount has been added to the gaming table 4.

[0254] Furthermore, the management control device 50 may compare the amount of gaming substitute currency added to the gaming table 4 (image payout amount) based on the image from the above-described camera device 2 with the amount of gaming substitute currency taken out from the gaming substitute currency tray 17, and verify whether the payout has been accurately performed. In this case, if the two do not match as a result of the comparison, the management control device 50 may turn on the display lamp.

[0255] As described above, basically, the dealer collects the game substitute currency 120 bet by the losing players in the order of the player position numbers. The management control device 50 determines whether the dealer has taken the chips in order according to this rule (the order of the player position numbers), and further determines whether the amount of the chips collected in order is correct. In this case, the management control device 50 determines, for each individual player position and in addition for the whole, up to which position the collection has been made (up to which player position's game substitute currency has been collected), and accordingly determines at each stage whether the game substitute currency 120 collected from the game table 4 has indeed been added to the game substitute currency tray 17. For example, when the dealer has collected the game substitute currency 120 for three positions, the management control device 50 determines whether the game substitute currency 120 for three positions has indeed been stored in the game substitute currency tray 17.

[0256] As described above, according to the present embodiment and its modification, since a display lamp 173 or the like for indicating whether the increase or decrease of the game substitute currency after the game in the game substitute currency tray 17 is accurate and / or inaccurate is provided, it is possible to confirm in real time whether the settlement has been accurately performed at the time of settlement.

[0257] As described above, various embodiments of the present invention have been described. However, it goes without saying that the above-described embodiments can be modified by those skilled in the art within the scope of the present invention, and the device of the present embodiment may be appropriately modified according to the requirements in the applicable game.

[0258] (Supplementary Note) The game substitute currency according to one aspect of the present invention comprises at least a colored layer and a white layer or a light-colored layer laminated to form a laminated structure composed of a plurality of plastic layers, with a stripe pattern in the lamination direction formed on the side surface. The type of the game substitute currency can be specified by the colored layer, and a printing layer representing the type of the game substitute currency is provided on the upper and lower surfaces of the laminated structure.
