Technical Field

[0003] This invention relates to a system for detecting cheating in games at amusement parks, or errors and cheating during the placement and calculation of game coins. Background Art

[0004] In amusement parks such as casinos, efforts are being made to prevent various forms of cheating. Amusement parks are equipped with surveillance cameras for monitoring cheating, and based on images obtained from the surveillance cameras, they determine cheating in games, and cheating such as the return and redemption of game coins that differ from the winning or losing result, thereby preventing cheating.

[0005] On the other hand, in order to keep track of the number and total amount of game coins placed, a scheme has been proposed to attach wireless IC (RFID) tags to each game coin to track the amount of game coins.

[0006] In the card game monitoring system described in International Publication No. 2015 / 107902, image analysis of changes in game coins is used to determine whether game coins placed on the game table are collected or returned according to the win or loss result, thereby monitoring cheating behavior. Summary of the Invention

[0007] Problem to be Solved by the Invention The object of the present invention is to provide a new system that detects cheating behavior in games at amusement parks, or errors and cheating behavior during the placement and calculation of game coins.

[0008] Solution to the Problem One aspect of the present invention is a cheating detection system for an amusement park with multiple game tables, comprising: a game recording device that records the state of a game played at the game table as an image using a camera; an image analysis device that performs image analysis on the recorded game state image; a win / loss result determination device that determines the win / loss result of each game at the game table; and a control device that uses the image analysis result of the image analysis device and the win / loss result determined by the win / loss result determination device to detect cheating behavior at the game table; the control device, by means of the image analysis device, grasps the position, type, and number of game coins placed by each player, and also grasps the total amount of game coins in the dealer's game coin tray at the game table, and adds to and subtracts the game coins in the game calculated based on the position, type, and number of game coins placed by all players in the game and the win / loss result obtained by the win / loss result determination device from the total amount of game coins in the game coin tray before each game settlement. (Specification 1 / 19 page 5 CN 121686628 A) The deduction is performed by comparing the total amount of game coins in the game coin tray after the game ends with the actual total amount of game coins in the game coin tray at the end of the game, obtained by the image analysis device, to determine whether there is a difference between the total amount and the actual total amount.

[0009] Alternatively, in the above-mentioned cheating detection system, the control device can use the image analysis device to grasp the position, type, and number of game coins placed by each player. When all the lost game coins placed by each player are collected, the actual total amount of game coins in the game coin tray is grasped. The total amount of game coins in the game coin tray before the game ends is added to the total amount of game coins in the game coin tray according to the position, type, and number of game coins placed by the losing player. The resulting total amount of game coins in the game coin tray is then compared with the actual total amount of game coins in the game coin tray to determine whether there is a difference between the total amount and the actual total amount.

[0010] Alternatively, in the above-mentioned cheating detection system, the control device can add the game coin tray's value to the total amount of game coins in the game coin tray before the game ends, according to the position, type, and number of game coins placed by the losing player.The total amount of game coins in the game coin tray, obtained by increasing the amount of game coins in the coin tray, is compared with the actual total amount of game coins in the coin tray. If there is no difference between the total amount and the actual total amount, and the total amount of game coins in the coin tray after the game ends is compared with the actual total amount of game coins in the coin tray at the end of the game obtained by the image analysis device, if there is a difference between the total amount and the actual total amount, it is determined as a payment error, and a payment error signal is generated to notify of the payment error.

[0011] Alternatively, in the above-mentioned cheating detection system, a game coin tray can be provided in the game coin tray to collect and temporarily store the game coins placed by the losing player. The image analysis device and the control device compare the total amount of game coins in the collected game coin tray calculated based on the position, type and number of game coins placed by the losing player with the actual total amount of game coins in the collected game coin tray to determine whether there is a difference between the total amount of game coins in the collected game coin tray and the actual total amount.

[0012] Alternatively, in the above-described cheating detection system, the actual total amount of game coins in the coin tray after the game ends can be determined by the image analysis device at any of the following times: 1) when the repayment of won game coins ends; 2) when the cards used in the game are recycled and discarded in the discard area of ​​the table; 3) when the designated button attached to the win / loss determination device is pressed; 4) when the sign indicating win / loss is restored.

[0013] Alternatively, in the above-described cheating detection system, in order to analyze the game recorder's record of the game that caused the difference when the control device determines that the actual total amount of game coins held in the coin tray of the dealer at the game table does not correspond to the increase or decrease of game coins calculated based on the amount of game coins placed by all players and the win / loss result of the game, the game recorder is configured to assign an index or time to the acquired image, or to determine and reproduce the scene of game coin recycling or payment.

[0014] In the above-mentioned cheating detection system, the image analysis device or control device may be configured to obtain information on the type, number, and location of the game coins even if multiple game coins placed on the game table are partially or entirely hidden due to the blind spot of the camera.

[0015] In the above-mentioned cheating detection system, the control device may be configured to perform the following actions: 1) Grasp the location, type, and number of game coins placed at each playing position on the game table, compare the historical win / loss records of each player and the amount of game coins obtained from the win / loss results of each game with the statistical data of past games, and extract them as an anomaly, or as per the specification 2 / 19 page 6 CN 121686628 A2) The state where the amount of game coins placed when losing is less than the amount of game coins placed when winning is compared with the statistical data of past games and extracted as an anomaly.

[0016] Alternatively, in the above cheating detection system, the control device can compare and determine whether the amount of game coins held in the game coin tray of the dealer at the game table has been increased or decreased after the exchange of banknotes and game coins, based on the payment amount of game coins corresponding to the exchanged banknotes or the payment amount of banknotes corresponding to the exchanged game coins.

[0017] Alternatively, in the above cheating detection system, the control device also has a database that stores the exchange history of banknotes and game coins, and can compare and determine whether the amount of game coins held in the game coin tray of the dealer at the game table has been increased or decreased based on the payment amount of game coins corresponding to the exchanged banknotes or the total amount of payment of banknotes corresponding to the exchanged game coins, by referring to the database at certain times or on a daily basis.

[0018] Alternatively, in the above-described cheating detection system, the control device can determine the player whose playing position is extracted as a difference or abnormal situation by means of the image analysis device.

[0019] Alternatively, in the above-described cheating detection system, the control device has a warning function that notifies the other game table of the presence of the specific player when the determined player leaves his / her seat and sits at another game table.

[0020] In the above-mentioned cheating detection system, the control device may also have the function of determining at least one of the following: 1) In each game, whether there is any change in game coins from the time the starting card is drawn or from the time the dealer starts the game until the game result is displayed by the card issuing device; 2) After each game ends, whether the loser does not take the game coins placed by the loser among the game participants during the time the dealer collects the game coins placed by the loser among the game participants; 3) After each game ends, whether additional game coins are added during the time the dealer collects the game coins placed by the loser among the game participants; 4) After each game ends, whether the dealer pays the game coins placed by the winner among the game participants; 5) After each game ends, whether the winner among the game participants takes the placed game coins and the game coins that are paid.

[0021] Alternatively, in the above-mentioned cheating detection system, the win / loss result determination device may be a card dispensing device that dispenses cards at the game table, or a control device that determines the win / loss result of each game based on information from an image analysis device that reads the cards dispensed at the game table using a camera.

[0022] Effects of the Invention According to the cheating detection system of the present invention, cheating in the recycling and repayment of game coins based on the win / loss result of the game can be detected.

[0023] Furthermore, according to the system of the present invention, even if the cards are repeatedly cheated by the player in a certain card game, etc.The system can bend under pressure, and the size and suit of the cards can be determined through image analysis. It can also detect the total amount and position of coins in blind spots and overlapping areas. Furthermore, it can detect cheating during the exchange of banknotes and coins.

[0052] (First Embodiment) In amusement parks such as casinos, game tokens are piled high on game tables. However, for IC tag reading devices placed under the game tables, there is a problem that the total amount cannot be accurately read. If the sensitivity of the reading device is increased, there is a problem that game tokens placed in different positions (by the left and right of the position) are totaled, making it impossible to grasp the total amount of game tokens in each position. Moreover, for the shooting from the camera, there is a problem that blind spots are formed due to the camera's angle, or that the image is blocked due to overlap, making it impossible to grasp the total amount of game tokens.

[0053] Moreover, although this is frequently done in a certain card game, there is a problem that: due to the player squeezing the card (bending the card face down, looking at the card's size little by little while waiting), the card is bent, and the size and suit of the card cannot be determined by the image analysis from the camera.

[0054] Furthermore, the following new problems arise: sophisticated cheating at game tables, where cheating based on advanced placement methods, which cannot be detected simply by detecting large winning amounts, cannot be detected by cameras or tracking winning amounts. Moreover, cheating based on collusion between the dealer and the player cannot be adequately prevented by existing technology.

[0055] In order to solve the above-mentioned problems, the cheating detection system for an amusement park with multiple game tables according to the first embodiment is a cheating detection system for an amusement park with multiple game tables, comprising: a game recording device that records the progress of the game at the game table, including the dealer and the player, as an image using a camera; an image analysis device that performs image analysis on the recorded game progress image; a card dispensing device that determines and displays the winning or losing results of each game at the game table; and a control device that uses the image analysis results of the image analysis device and the winning or losing results determined by the card dispensing device to detect cheating behavior at the game table.

[0056] In addition, in the cheating detection system, the card dispensing device is configured to read the card size of the dispensed cards, and the control device is configured to compare the card size information obtained by the image analysis device from the image of each card dispensed at the game table with the card size information read by the card dispensing device to determine whether they are consistent or not.

[0057] In addition, in the cheating detection system, the image analysis device or control device is an artificial intelligence-efficient or deep learning-based structure that can obtain card size information from cards dispensed at the game table that have been bent or soiled by the player.

[0058] In addition, in the cheating detection system, the control device uses the image analysis device to grasp the position, type, and number of game coins placed by each player, and uses the image analysis device to analyze the image of the game's progress to determine whether the lost game coins placed by each player have been correctly recovered and the won game coins have been paid out according to the game's winning and losing results.

[0059] Furthermore, in the cheating detection system, the image analysis device or control device is an AI-efficient or deep learning-based structure that can obtain information about the type, number, and location of the placed game coins even when multiple game coins placed on the game table are partially or entirely hidden due to the blind spot of the camera.

[0060] Furthermore, in the cheating detection system, the control device is an AI-efficient or deep learning-based structure that can compare and calculate the amount of game coins held in the dealer's game coin tray according to the game's winning or losing results, and after the game ends and is settled, adjust whether to recover the lost game coins placed by each player and increase or decrease the payout amount for the won game coins.

[0061] Furthermore, in the cheating detection system, the control device is an AI-efficient or deep learning structure capable of grasping the position and amount of game coins placed at each playing position of the game table, comparing the historical win / loss records of each player and the amount of game coins obtained from the win / loss results of each game with the statistical data of past games, and extracting anomalies.

[0062] Furthermore, in the cheating detection system, the control device is an AI-efficient or deep learning structure capable of comparing the state where the amount of game coins placed when losing is less than the amount of game coins placed when winning at a certain playing position of the game table with the statistical data of past games, and extracting anomalies.

[0063] Furthermore, in the cheating detection system, the control device is a structure capable of identifying individual players at playing positions where anomalies are extracted by means of the image analysis device, or where a player has won by a predetermined amount or more.

[0064] Furthermore, in the cheating detection system, the control device has a warning function that notifies the other game table of the presence of the specific player when the identified player leaves and sits at another game table.

[0065] In order to solve the above-mentioned problems, the cheating detection system for an amusement park with multiple game tables of the present application comprises: a game recording device, which records the progress of the game at the game table, including the dealer and players, as an image using a camera; a card dispensing device, which determines and displays the winning or losing results of each game at the game table; an image analysis device, which performs image analysis on the recorded game progress images; and a control device, which can use the image analysis results of the image analysis device to detect banknotes and game coins at the game table; The image analysis device or control device is an AI-efficient or deep learning structure that utilizes the following: Based on information obtained from the card dispensing device or the dealer, it can detect, outside of the card distribution process, the exchange of banknotes and game coins at the game table, and recognize the total amount of the banknotes verified by near-ultraviolet light. Even if multiple game coins taken from the game table as exchange objects are partially or entirely hidden due to blind spots in the camera, the total amount of game coins can still be recognized. The total amount of banknotes taken from the player and the total amount of game coins taken from the dealer at the game table can be compared to determine if they are consistent.

[0066] Furthermore, in the cheating detection system, the control device is an AI-efficient or deep learning structure that can compare and calculate the amount of game coins held in the dealer's game coin tray at the game table, and whether, after the exchange and settlement of banknotes and game coins, adjustments are made based on the payment amount of game coins corresponding to the exchanged banknotes.

[0067] In addition, in the cheating detection system, the control device is constructed using artificial intelligence or deep learning in the following way: [Instructions for use]Page 6 / 19 10 CN 121686628 A After the exchange and settlement of banknotes and game coins, the system compares and calculates the consistency between the banknote amount generated by the dealer's input and the total amount of banknotes based on the image analysis result of the image analysis device. Moreover, the control device is also constructed to effectively utilize artificial intelligence or deep learning: it is able to compare and calculate the consistency between the total amount of banknotes generated by the dealer based on the dealer's input at the game table and the total amount of banknotes based on the image analysis result of the image analysis device.

[0068] According to the cheating detection system of this embodiment, even if a card is bent due to repeated squeezing of the card by a player in a card game, the card size and suit can be determined by image analysis, and the total amount and position of game coins in blind spots and overlapping areas can also be grasped. Moreover, cheating during the exchange of banknotes and game coins can also be detected.

[0069] Hereinafter, the overall outline of the cheating detection system in an amusement park with multiple game tables according to the first embodiment of the present invention will be described in further detail. FIG1 is a diagram showing the overall outline of the same system. The cheating detection system in an amusement park with multiple game tables 4 includes: a game recording device 11, which records the progress of the game played at the game table 4, including the player 6 and the dealer 5, as images through multiple cameras 2; an image analysis device 12, which performs image analysis on the recorded images of the game progress; and a card dispensing device 3, which determines and displays the winning or losing result of each game at the game table 4. The card dispensing device 3 is a so-called electronic shoe used by those skilled in the art. It is configured to pre-program the rules of the game, read the information of the dealt card C, and determine the winning or losing result of the game. For example, in a certain card game, the outcome of a win for player B, a win for player P, or a draw is basically determined by the face value of 2-3 cards, and the determination result (winning or losing result) is displayed by the result display light 13.

[0070] This cheating detection system also includes a control device 14, which compares the actual card face value based on the image analysis results of the image analysis device 12 with the win / loss result determined by the card dispensing device 3, and detects cheating behavior (such as inconsistency between the total face value of the cards distributed and the win / loss result) performed at the game table 4. The card dispensing device 3 is configured to read the face value (A, 2-10, J, Q, K) and suit (hearts, spades, etc.) of the cards C manually distributed by the dealer 5. The control device 14 is configured to compare the card face value and suit information obtained by the image analysis device 12 (using artificial intelligence) from the images of each card distributed at the game table 4 (captured using the camera 2) with the card and suit information read by the card dispensing device 3, and determine whether they are consistent or inconsistent. This cheating detection systemThe image analysis device 12 and control device 14 are constructed as an integral or composite unit, comprising a computer, program, and memory.

[0071] The image analysis device 12 and control device 14 are equipped with an artificial intelligence-efficient or deep learning structure that can obtain information about the card size even if a card C is dealt on the game table 4 and bent or soiled by player 6. As shown in Figure 4, a soiled card C is difficult to distinguish as either club or spade. Even in such cases, the suit can be determined by analyzing and judging the image using an artificial intelligence-efficient computer or control system and deep learning (construction) technology. Furthermore, even if a card is bent due to repeated squeezing by players in a card game, the suit and card size of the card before deformation can be identified by using self-learning from multiple image deformation examples, through an artificial intelligence-efficient computer or control system and deep learning (construction) technology. The computer or control system that effectively utilizes artificial intelligence and the deep learning (construction) technology are well known and can be used by those skilled in the art, so detailed descriptions are omitted.

[0072] Specifically, the control device 14 that effectively utilizes artificial intelligence or the deep learning construction can, through the camera 2 and the image analysis device 12, determine which position (P, B, or PAIR) each player 6 places in the placement area 8, the type of game coin 9 (game coins 9 are assigned different values ​​according to each color), and the number of coins. The game coins 9 may not only be arranged and overlapped in the vertical direction, but also may be staggered and overlapped as shown in Figure 2A. In this case, when the camera 2 is in the direction of arrow X shown in Figure 2A (or the game coin 9 is facing a blind spot), as shown in Figure 2B, it can be imagined that the game coin 9 cannot be seen (entering a blind spot). Artificial intelligence-efficient computer or control system, deep learning (construction) technology, etc., can use self-learning functions to identify the concealment of game coins 9 due to blind spots (the case where part of a game coin is concealed, or the game coin is concealed entirely), and accurately grasp the number of coins. In this way, since it can grasp the position (P, B, or PAIR) of the game coin 9 in the placement area 8, the type of game coin 9 placed (game coins 9 are assigned different values ​​according to each color) and the number of coins, in each game, according to the game's winning or losing result determined by the card dispensing device 3, the control device 14 analyzes the image of the game's progress state by means of the image analysis device 12 to determine whether the game coins lost by each player 6 have been correctly collected (indicated by arrow L) and the winning game coins (9W) have been paid to the winning player 6W according to the game's winning or losing result.

[0073] The control device 14 can use the image analysis device 12 to analyze and monitor the total amount of game coins 9 in the coin tray 17 of the dealer 5 at the game table 4. After the game ends and is settled, it can compare and calculate whether the total amount of game coins 9 in the coin tray 17 corresponds to the recovery of the lost game coins 9 placed by each player 6 and the payment of 90,000 won game coins to the winning player 60,000, based on the game's winnings. Even though the total amount of game coins 9 in the coin tray 17 is monitored through RFID and other means, the control device 14 determines the accuracy of this increase or decrease by analyzing the game's progress using the image analysis device 12. This also effectively utilizes artificial intelligence or deep learning structures.

[0074] In this example, since cheating or errors are detected based on the game's outcome, the type and quantity of game coins 9 placed in which position (P, B, or PAIR) of the placement area 8, and the increase or decrease in the amount of game coins 9 in the game coin tray 17 after the recovery of lost game coins and the repayment of won game coins 9, cheating or errors can be detected even without knowing the changes in game coins 9 after the game ends, i.e., whether the placed game coins 9 move to the player's side or to the dealer's side.

[0075] Here, for example, in the case of a card game, the outcome of the game can be determined by reading the face value of the cards C successively dealt by the card dispensing device 3 in the game, according to the rules of the card game. Moreover, by using the camera 2 to photograph the game table 4, analyzing the image using the image analysis device 12, and comparing the analysis results with the rules of the game using the control device 14, the outcome of the game can also be determined. In this case, the camera 2, the image analysis device 12, and the control device 14 constitute the outcome determination device. Information regarding which type and how many game coins 9 players placed in which position (P, B, or PAIR) of the placement area 8 can be obtained by the camera 2 capturing images of the game coins 9 placed in the placement area 8 and analyzing those images by the image analysis device 12 for each playing position 7.

[0076] Furthermore, the increase or decrease in the amount of game coins 9 in the game coin tray 17 before and after the recycling of lost game coins 9 and the repayment of won game coins 9 can be calculated by comparing the total amount of game coins 9 in the game coin tray 17 before the recycling of lost game coins 9 and the repayment of won game coins 9 with the total amount of game coins 9 in the game coin tray 17 after the recycling of lost game coins 9 and the repayment of won game coins 9. The total amount of game coins 9 in the game coin tray 17 before the recycling of lost game coins 9 and the repayment of won game coins 9, and the total amount of game coins 9 in the game coin tray 17 after the recycling of lost game coins 9 and the repayment of won game coins 9 are calculated.The total amount of game coins 9 can be detected by the image analysis device 12 analyzing the images taken by the camera 2 of the game coin tray 17 containing the game coins 9. Alternatively, the total amount of game coins 9 stored in the game coin tray 17 can be detected by embedding an RFID tag indicating its amount inside the game coin 9 and installing an RFID reader on the game coin tray 17. Specification 8 / 19 pages 12 CN 121686628 A

[0077] For example, let the total amount of game coins 9 in the game coin tray 17 before the game starts be Bb, and the total amount of game coins 9 in the game coin tray 17 after the game ends and the lost game coins are collected and the won game coins are repaid be Ba. In addition, in this game, the total amount of all play positions 7 of game coins 9 placed in area P is bp, the total amount of all play positions 7 of game coins 9 placed in area B is bb, and the total amount of all play positions 7 of game coins 9 placed in the tie area is bt. For example, if player B wins the game, Ba - Bb = bp - bb + bt should hold. Alternatively, the total amount Ba of game coins 9 in the game coin tray 17 after the game should be (Bb + bp - bb + bt). If this is not the case, it can be determined that there is cheating or error in the recycling or repayment of game coins.

[0078] FIG3A is a diagram showing the detailed situation of the game coin tray of this embodiment, and FIG3B is a diagram showing other examples of the game coin tray. The game coin tray 17 is provided with a recycling game coin tray 171 and a repayment game coin tray 172. The recycling game coin tray 171 recycles and temporarily stores the game coins 9L placed by the losing player 6L, and the repayment game coin tray 172 stores the game coins 9W to be repaid. The image analysis device 12 and the control device 14 grasp the position, type and number of game coins 9L placed by the losing player 6L, and calculate the increase of game coins 9L in the game (the due amount of game coins 9 in the recycling game coin tray 171). Furthermore, the image analysis device 12 and the control device 14 determine the actual total amount of game coins 9 in the recycled game coin tray 171, and compare the total amount with the actual total amount to determine if there is a difference.

[0079] In addition, by using the game coin tray 172 to repay the 60,000 game coins 90,000 to the winning player, sufficient time can be ensured for the image analysis device 12 and the control device 14 to determine the actual total amount of game coins 9 in the recycled game coin tray 171.

[0080] The game table 4 has a discard area 41 and / or a discard slit 42 for discarding cards C used in the game. At the end of each game, the cards C used in the game are recycled and placed in the discard area 41 or the discard slit 42 on the game table 4 for disposal.

[0081] The game table 4 also has a sign 43 indicating the win or loss of the game. Figure 5A is a top view showing the front of the sign, and Figure 5B is a top view showing the back of the sign. In a certain card game, two signs are used: a sign 43a indicating that player P wins and a sign 43b indicating that player B wins. When the game result is announced, the dealer 5 flips over the sign of the winning player, either P or B. Thus, the win or loss of the game is clearly displayed on the table. The flipped sign is restored by the dealer 5 after the game coins 9 are collected and returned. By restoring the sign, it also means that the game can start the next game.

[0082] As described above, in this embodiment, the control device 14 calculates the income and expenditure of game coins for each game based on the amount of game coins placed on the game table 4 and the win or loss result of the game, and verifies the increase in the balance of game coins in the game coin tray 17 after the game. If the control device 14 detects a discrepancy in this verification, it issues an alarm or adds a record indicating the situation to the video recording captured by the camera 2. Casino operators can investigate the cause of the discrepancy by reviewing the video.

[0083] In the cheating detection system of this embodiment, the total amount of game coins 9 in the game coin tray 17 before the settlement of each game is added to and subtracted from the increase or decrease of game coins in the game calculated based on the position, type and number of game coins 9 placed by all players 6 in the game and the win or loss result of the game obtained by the win or loss result determination device. The system then compares the total amount of game coins 9 that should have been in the game coin tray 17 after the settlement at the end of the game with the actual total amount of game coins 9 in the game coin tray 17 at the end of the game obtained by the image analysis device 12, and determines whether there is a discrepancy between the total amount that should have been in the game coin tray 17 and the actual total amount.

[0084] The control device 14 uses the image analysis device 12 to grasp the position, type and number of game coins placed by each player. When all the lost game coins placed by each player are collected, the control device 14 grasps the actual total amount of game coins in the game coin tray. The control device 14 compares the total amount of game coins in the game coin tray before the settlement of each game with the actual total amount of game coins in the game coin tray 17 obtained by adding the increase of the game coin tray 17 in the game according to the position, type and number of game coins placed by the losing players on page 9 / 19 of the instruction manual 13 CN 121686628 A, and determines whether there is a difference between the expected total amount and the actual total amount.

[0085] The control device 14 calculates the total amount of game coins 9 in the game coin tray 17 before each game's settlement, based on the position, type, and number of game coins 9 placed by the losing player, plus the increase in the game coin tray 17 for that game, and the actual total amount of game coins 9 in the game coin tray 17.The image analysis device 12 compares the total amount of game coins in the game coin tray 17 after the game ends with the total amount of game coins 9 in the game coin tray 17 after the game ends, and determines that there is no difference between the total amount of game coins 9 and the actual amount of game coins 9 in the game coin tray 17 after the game ends, and determines that there is a difference between the total amount of game coins 9 and the actual amount of game coins 9 in the game coin tray 17. If there is a difference between the total amount of game coins 9 and the actual amount of game coins 9 in the game coin tray 17, a payment error signal is generated to notify the payment error.

[0086] The game coin tray 17 is provided with a game coin tray 171 for collecting and temporarily storing the game coins 9 placed by the losing player. The image analysis device 12 compares the total amount of game coins 9 in the game coin tray 171 after adding the increase of game coins 9 in the game based on the position, type and number of game coins 9L placed by the losing player, and the actual amount of game coins 9 in the game coin tray 171 to determine whether there is a difference between the total amount of game coins 9 and the actual amount of game coins 9 in the game coin tray 171.

[0087] In order to address the discrepancy between the actual total amount of game coins 9 held in the coin tray 17 of the dealer 5 at the game table 4, as determined by the control device 14, and the increase or decrease in game coins calculated based on the total amount of game coins placed by all players and the winning or losing result of the game, the game recording device 11 is configured to analyze the game record that caused the discrepancy. The game recording device 11 is configured to index or time the acquired images, or to determine and reproduce the scene of the game coin 9 being collected or paid.

[0088] Thus, the control device 14 obtains the total amount of game coins in the coin tray 17 after the game ends by means of the image analysis device 12. However, the determination after the settlement in this case occurs at the moment when any of the following 1) to 4) occurs: 1) when the repayment of the won game coins 9 ends; 2) when the card C used in the game is collected and discarded in the discard area 41 or discard slit 42 of the table; 3) when the predetermined button attached to the winning or losing result determination device is pressed; 4) when the winning or losing indicator 43 is restored.

[0089] Furthermore, the control device 14 is configured to effectively utilize artificial intelligence or employ deep learning: it can grasp the position (position of P, B, or PAIR) and amount (type and number) of game coins placed at each play position 7 of the game table 4, and compare the win / loss history of each player 6 obtained from the win / loss results of each game with the amount of game coins won (the amount won) with the statistical data of many past (big data) games, and extract anomalies (set by the casino). Typically, it is a device with a control device 14 configured to effectively utilize artificial intelligence or employ deep learning: the occurrence of winning amounts of a certain amount (1 million points) or more, or the state where the amount of game coins placed when losing at a certain play position 7 of the game table 4 is small while the amount of game coins placed when winning is large, continues in multiple games, which is consistent with the statistics of past games.Data (big data, etc.) is compared, and this can be extracted as an anomaly.

[0090] Furthermore, the control device 14 of this cheating detection system (integrated with the image analysis device 12) is configured to identify individual players 6 at the playing position 7 who have been extracted as an anomaly or have won a specified amount or more. For the identification of such players 6, the image analysis device 12 obtains an image of the face through feature point extraction, etc., and assigns an identification number (ID, etc.) to identify them. Moreover, the control device 14 has a warning function that notifies other game tables of the presence of the specific player when the identified player 6 leaves his seat and sits at another game table. Specifically, it notifies the manager or person in charge of each game table 4 (or the dealer) to prevent more abnormal phenomena.

[0091] The control device 14 also has a database containing exchange history records of banknotes K and game coins 9. By referring to the database at regular intervals or on a daily basis, it compares and determines whether the amount of game coins 9 held in the coin tray 17 of the dealer 5 at the game table 4 has increased or decreased based on the payment amount of game coins 9 corresponding to the exchanged banknotes K, or the total amount of payment of banknotes K corresponding to the exchanged game coins 9.

[0092] Furthermore, in the above example, it is possible to monitor the win / loss history and the amount of game coins (wins) obtained for each playing position 7 without considering individual players 6. In this case, although it is not possible to track and investigate players 6 when they leave their seats, it is possible to detect abnormal situations such as a situation where the amount of game coins placed when losing is small and the amount of game coins placed when winning is large in multiple games at a specific playing position 7 of the game table 4. Moreover, if such a playing position 7 is detected, cheating or errors are suspected at that playing position 7. Furthermore, by verifying the video of the playing position 7, cheating or errors can be discovered.

[0093] Specifically, the camera 2 is configured to capture images of the game coins 9 placed in the placement area 8 of the game table 4. The image analysis device 12 analyzes the images captured by the camera 2 and, according to each user position 7, detects which position (P, B, or tie) in the placement area 8 has game coins placed and the amount of game coins placed there. Furthermore, the card dispensing device 3 functions as a win / loss determination device, determining the win / loss outcome of the game. The control device 14 records (monitors) the win / loss history and the amount of game coins obtained (game coin acquisition amount) for each playing position 7 based on the position (P, B, or tie) in the placement area 8 where the game coins 9 are placed and the win / loss outcome of the game. Alternatively, only either the win / loss history or the game coin acquisition amount may be recorded. The control device 14 records the win / loss history and / or the game coin acquisition amount history.If the recorded data is compared with the statistical data of many past (big data) games and an anomaly is found (set by the casino), then player position 7 is identified as a playing position suspected of cheating.

[0094] If cheating is suspected at player position 7, the cheating detection system can generate an alarm (light, sound, or vibration) in a manner that at least the dealer can detect at that time. Thus, the cheating can be prevented from continuing by interrupting the game at least at that location. In addition, information indicating that cheating is suspected can be added to the video captured and recorded by camera 2. Thus, the cause of the suspected cheating can be investigated by reviewing the video.

[0095] The cheating detection system in the arcade with game tables of this embodiment also has the function of checking the exchange of banknotes and game coins that are repeatedly performed on the game table 4. In arcades such as casinos, before the game, player 6 exchanges banknotes (cash, etc.) and game coins at a designated game coin exchange location. However, when player 6 runs out of game coins, without leaving game table 4, they can exchange cash (paper money) for game coin 9 at the game table (such as a card game table) and continue playing. However, this creates an opportunity for cheating between the dealer 5 and the player. Exchanging cash (paper money) for game coin 9 at the game table (such as a card game table) must be done when not playing. The card dispensing device 3 can detect the start and end of card dealing (the period for determining the winner) to determine the outcome of the game. Therefore, the card dispensing device 3 detects situations other than card dealing (dealing), and the control device 14 detects that an exchange of paper money and game coin 9 is taking place at game table 4 (shown in Figure 6), even in situations other than card dealing (dealing). For situations involving card dealing (or other than this), detection can be performed based on information obtained from the actions of the card dispensing device 3 or the dealer 5.

[0096] The control device 14 performs image analysis on the surface of the banknote K, and can identify the number and amount of banknotes. Furthermore, on the game table 4, to verify whether the banknote K used for exchanging with the game coin 9 is genuine, the authenticity mark G of the banknote is detected by irradiating it with near-ultraviolet light. As shown in FIG6, the control device 14 is constructed with the following artificial intelligence effective utilization or deep learning: it also performs image analysis on the authenticity mark G to verify it, recognizes the total amount of genuine banknotes, and even if multiple game coins taken from the game table as exchange objects are hidden due to the blind spot of the camera 2, it can still recognize the total amount of game coins, and can compare the total amount of banknote K taken from the player on the game table 4 with the total amount of game coins 9 taken from the dealer 5 to determine whether the two amounts are consistent.

[0097] The control device 14 is constructed using artificial intelligence or deep learning: it can compare and calculate the total amount of game coins 9 in the game coin tray 17 of the dealer 5 at the game table 4, and whether the amount has increased or decreased according to the payment amount of game coins corresponding to the exchanged banknotes after the exchange and settlement of banknotes and game coins. It is also possible to use the RFID of game coins 9 to keep track of the total amount of game coins 9 in the game coin tray 17 of the dealer 5 in advance. In addition, by using the camera 2 to take a picture of the game coin tray 17 containing game coins 9, and using the image analysis device 12 to analyze the image, the total amount of game coins 9 in the game coin tray 17 can also be detected.

[0098] Moreover, the control device 14 verifies whether the increase or decrease of the amount of game coins 9 in the game coin tray 17 before and after the exchange of banknotes and game coins is consistent with the exchange amount of game coins in the image analysis result on the game table 4. The amount of banknotes already paid can be input by the dealer 5 via keyboard input or the like into the control device 14, or the camera 2 can be used to capture an image of the game table 4 where banknote payments are made, and the image can be analyzed by the image analysis device 12 to determine the amount.

[0099] As described above, the control device 14 determines whether the reduction in the value of the game coin 9 in the game coin tray 17 caused by the exchange of banknotes and game coins is consistent with the amount of banknotes paid by the player 6 to the dealer 5. Furthermore, the control device 14 is an intelligent control device capable of comparing and calculating the consistency between the banknote amount received by the dealer 5 (usually based on keyboard input, etc.) and the calculated amount of banknotes based on the image analysis results of the image analysis device 12 after the exchange and settlement of banknotes and game coins. It can also be an artificial intelligence-efficient or deep learning-based control device.

[0100] Furthermore, the control device 14 is an artificial intelligence-efficient or deep learning construct capable of comparing and calculating the consistency between the total amount of banknotes input by the dealer at the game table 4 under the dealer's responsibility and the total amount of banknotes based on the image analysis results of the image analysis device 12.

[0101] The control device 14 compares and determines whether the amount of game coins 9 held in the game coin tray 17 of the dealer 5 at the game table 4 has been increased or decreased after the exchange of banknotes and game coins 9, based on the payment amount of game coins 9 corresponding to the exchanged banknotes or the payment amount of banknotes corresponding to the exchanged game coins 9.

[0102] (Second Embodiment) Among the many table games played in amusement parks such as casinos, there is a certain card game. These games use a standard deck of 52 cards, which are dealt to the game table from a card-dealing device containing pre-shuffled multiple decks (from 6 to 9 or 10 decks). The winner is determined by the number of cards dealt (card value) and the game rules.

[0103] The distribution of cards from the card-dispensing device and the calculation of the amount placed by the customer (game participant) are carried out by the dealer or other personnel responsible for the game table. In amusement parks and other entertainment venues, efforts are being made to prevent errors and cheating in the calculation of the amount placed by the customer (game participant).

[0104] In the card game monitoring system described in International Publication WO2015 / 107902, a surveillance camera is used to read the changes in game coins and check whether the amount placed has been paid to the winner.

[0105] Regarding the placement of cards by the customer in a certain card game and the calculation of the amount placed by the dealer, there are the following problems: it is not possible to detect when these actions are carried out, who placed the game coins, or whether they have been taken away, so it is impossible to ascertain whether these actions are correct.

[0106] To solve the above-mentioned problems, the cheating detection system of the second embodiment is a cheating detection system for an amusement park with a game table, comprising: a game monitoring device that uses a camera to monitor the progress of games played at the game table; an image analysis device that performs image analysis on the images obtained by the camera; a card dispensing device that determines and displays the winning and losing results of each game at the game table; and a control device that uses the analysis results of the image analysis device in each game to determine the position of the game coins placed on the game table by the game participants, and uses the winning and losing results to determine the winner and loser among the participants of each game; the control device also has the function of determining at least one of the following: 1) In each game, whether there is any change in game coins from the time the starting card is drawn or from the time the dealer starts the game until the winning and losing results are displayed by the card dispensing device. 2) After each game ends, during the period when the dealer collects the game coins placed by the losers among the game participants, are there any changes in the game coins caused by anyone other than the dealer? 3) After each game ends, during the period when the dealer collects the game coins placed by the losers among the game participants, are any additional game coins added? 4) After each game ends, does the dealer pay the game coins placed by the winners among the game participants? 5) After each game ends, do the winners among the game participants take the placed game coins and the game coins that were paid?

[0107] Furthermore, the control device may also be configured to detect changes in the hands of the dealer and game participants, changes in game coins, or changes in the hands and changes in game coins by using the analysis results of the image analysis device, thereby determining at least one of 1) to 5).

[0108] Furthermore, the control device may also be configured to determine whether the amount of game coins paid by the dealer to the winner is correct based on the amount placed by the winner among the game participants.

[0109] Furthermore, the cheating detection system for the game may also include a monitor or light that receives the judgment result and issues a warning or display.

[0110] According to the cheating detection system of this embodiment, the system can detect the timing of the placement of game coins by a guest in a card game and the calculation of the amount of coins placed by the dealer for the guest (game participant). It can detect these errors and cheating behaviors and issue warnings or displays, thereby preventing them from happening again.

[0111] Before proceeding to the detailed description of this embodiment, the process of a card game played in an amusement park such as an entertainment venue will be described. In the second embodiment, the same components as in the first embodiment will be described with the same numbers.

[0112] As shown in FIG7, on the game table 4, the guest (game participant / player) 6 and the dealer 5 sit facing each other on the playing position (chair) 7. Furthermore, the guest (game participant) 6 places game coins 9 in the placement area 8 in front of them, placing them to determine the outcome of a card game, whether P (PLAYER) or B (BANKER) wins, or whether it results in a tie (hereinafter referred to as "placement"). Additionally, the dealer 5 times the timer to complete the placement by the guest (game participant) 6, calling out "No More Bet (placement processing complete)," and performing actions such as moving their hand horizontally (as shown in Figure 7). During the period from the time "No More Bet (placement processing complete)" is called, when cards are drawn or the dealer 5 begins the game, until the game's outcome is displayed via the card dispensing device 3, the guest (game participant) 6 cannot move game coins, place additional game coins, or retrieve placed game coins. Instruction manual, pages 13 / 19, CN 121686628 A

[0113] Then, the game cards 1 are drawn one by one from the card dispensing device 3, face down, onto the game table 4. First, four cards are drawn, as shown in ① to ④ of Figure 8. The first card belongs to P (PLAYER), the second card belongs to B (BANKER), the third card belongs to P (PLAYER), and the fourth card belongs to B (BANKER). They are arranged in areas 10 (P area 10P and B area 10B) that are visible from the dealer 5 on the game table 4. Moreover, based on the face value (number) of the first to fourth cards 1 and the conditions in the detailed rules of a certain card game, the dealer 5 draws the fifth card 1 and the sixth card 1, which belong to P (PLAYER) or B (BANKER). Next, based on the face value (number) of the first to fourth cards (and, depending on the situation, the fifth and sixth cards) and the detailed rules of a certain card game, the winner of the game is determined. Here, the structure is as follows:In the card dispensing device 3, the rules of the game are pre-programmed, and the information of the cards 1 (card size (number) and suit) can be read to determine the winner of the game. The winner determination result (win result) determined by the card dispensing device 3 is judged to be consistent with the winner determination result determined by the dealer, etc. as described above.

[0114] Hereinafter, an overall overview of the cheating detection system in the game of the amusement park according to the embodiment of the present invention will be described. FIG7 is a diagram showing an overall overview of the same system. The cheating detection system in the game of the amusement park includes: a game recording device 11, which records the progress of the game at the game table 4, including the guests (game participants) 6 and the dealer 5, as an image through a camera 2; an image analysis device 12, which performs image analysis on the recorded game progress image; and a card dispensing device 3, which has the function of determining and displaying the winner of each game at the game table 4. The card dispensing device 3 is a so-called electronic shoe already used by those skilled in the art. It is configured to pre-program the rules of the game and can detect when the dealer 5 dispenses the cards 1 at the beginning of each game. It also reads the information of each card 1 (card size (number) and suit) to determine the winner of the game. For example, in a certain card game, the winner of B, the winner of P, and the draw are basically determined by the size of 2-3 cards. The result (win or lose result) is displayed by the indicator light 13.

[0115] The control device 14 of this cheating detection system has a game coin detection function. This game coin detection function uses the analysis results of the image analysis device 12 in each game to determine which placement area 8, P side or B side, the guest 6 (game participant) has placed the game coin 9 on. Regarding the location and total amount of game coin 9 (which placement area 8 on the P side or B side is game coin 9 placed in), it is conceivable that if game coins 9 are staggered or overlapped, or if they fall into a blind spot from the position of camera 2, they usually cannot be read. The control device 14 is configured to use a computer or control system that effectively utilizes existing artificial intelligence, a self-learning function based on deep learning (construction) technology, etc., to identify the concealment of game coins 9 due to blind spots (the case of partial concealment of a game coin, or the case of the game coin being completely concealed), and accurately grasp the location and number of coins. Furthermore, the configuration for detecting the location and type of game coin 9 in placement area 8 is not limited to this; for example, it can also be configured to detect by reading the ID embedded in the game coin.

[0116] As described above, the control device 14 can, with the aid of the camera 2 and the image analysis device 12, determine the position (placement against P, B, or PAIR), type (different values ​​are assigned to each color of the game coin 9), and number of coins placed by each player 6. It can also detect which player 6 placed the coin against P (in cases where there are multiple players 6 placed against P).Under this system, the highest amount is placed by guest 6), and the highest amount is placed by guest 6 (if there are multiple guests 6 placed by guest 6, the highest amount is placed by guest 6). The image analysis device 12 and the control device 14 in this cheating detection system are constructed as a single unit or as a composite, comprising a computer, program, and memory.

[0117] The control device 14 is constructed as follows: it can compare the information on the card size and suit obtained by the image analysis device 12 from the image of each card 1 dealt at the game table 4 (using the camera 2) with the information on the card size and suit read by the card dealing device 3, and determine whether they are consistent or inconsistent. According to the winning or losing result of the game determined by the card dispensing device 3 in each game, the control device 14 analyzes the image of the game's progress state by means of the image analysis device 12 to determine whether the lost game coins 9 placed by the guest (game participant) 6 and the winning game coins paid to the winning guest (game participant) 6 have been correctly collected according to the winning or losing result of the game.

[0118] The control device 14 has the following functions as shown in 1) to 5) according to the rules of a certain card game. As a characteristic function of the present invention, it determines whether cheating that violates the rules has not been carried out. That is, 1) In each game, the control device 14 monitors (as shown in FIG8) the period from the signal of the start card being drawn from the card dispensing device 3, or from the start of the game operation when the dealer 5 presses the start button for 4 seconds, until the winning or losing result of the game is displayed by the card dispensing device 3, whether there has been any change in the game coins 9.

[0119] 2) After each game, using the information obtained by the image analysis device 12 using the camera 2, monitor whether the loser 6 took the game coin 9 without cheating during the period when the dealer 5 was collecting the game coin 9 placed by the loser among the game participants 6 (as shown in Figure 9).

[0120] 3) After each game, using the information obtained by the image analysis device 12 using the camera 2, monitor whether anyone other than the dealer 5 (winner or loser) added the won game coin 9W, or whether they did not replace the game coin 9 on the winning side where it was not placed, during the period when the dealer 5 was collecting the game coin 9 placed by the loser among the game participants 6.

[0121] 4) After each game, using the information obtained by the image analysis device 12 using the camera 2, monitor whether the dealer 5 correctly placed the paid game coin 9W at the position of the game coin 9 placed by the winner among the game participants 6 (as shown in Figure 10).

[0122] 5) After each game ends (the dealer 5 operates the card distribution device 3 and displays the winning and losing results on the display light 13), the information obtained by the image analysis device 12 using the camera 2 is used to monitor whether the winner 6W among the game participants 6 has taken the prize.The game coin 9 placed and the game coin 9W paid (as shown in Figure 11).

[0123] The control device 14 analyzes the information obtained by the image analysis device 12 using the camera 2 as follows. That is, by using the analysis results of the image analysis device 12, the changes in the hands of the dealer 5 and the game participant 6, the changes in the game coin, or the changes in the hands and the changes in the game coin are detected to monitor 1) to 5). However, in this basic analysis, it is necessary to know at least who took the game coin 9. Hereinafter, the method of this analysis will be described using Figures 12 to 14.

[0124] Analysis of the case where the dealer 5 takes the game coin 9 placed by the game participant 6L (Figure 12).

[0125] The dealer 5 recovers the game coin 9 placed by the game participant 6L who lost in the game. The recovery is monitored by analyzing the information obtained by the image analysis device 12 using the camera 2. First, image analysis is used to detect the change of the placed game coin 9 from its present state (Fig. 12A) to its non-present state (Fig. 12C). Then, the image (Fig. 12B) during the period when the game coin 9 is in the present state to the non-present state is analyzed. In the image (Fig. 12B) during the period when the game coin 9 is in the present state to the non-present state, the direction from which the hand 5h extends (from above or outside of Fig. 12) is analyzed. If it extends from above (or the hand appears from above and then withdraws upwards), the hand 5h is determined to belong to the dealer 5. If the hand extends from a direction other than this, it is determined to be cheating. Cheating is detected according to this rule.

[0126] During the period when the dealer 5 collects the game coin 9 placed by the losing game participant 6L, it is monitored whether other people take the lost game coin 9 without cheating (Figs. 12 and 11). As shown in Figure 13, in the image during the period from the presence of game coin 9 to its absence, the analysis of the case where the losing player 6L among the game participants 6 takes the coin is determined by detecting the hand 6h extending or moving from below (originally from above) in Figure 13 through image analysis. This is determined to be the hand 6h or others other than the dealer 5 taking the game coin 9, and this is determined to be cheating. Manual 15 / 19 pages 19 CN 121686628 A

[0127] Analysis of the case where the dealer 5 correctly pays (places) game coin 9W for the won game coin 9, and the winning player 6W among the game participants 6 takes it. First, the won game coin shown in Figure 14A is paid back according to the rules of the game as shown in Figure 14B. The change from the state shown in Figure 14A to the state shown in Figure 14B is detected, and at the same time, the hand is detected by image analysis to see if it is the dealer 5's hand 5h. Then, the control device 4, according to the rules of the game,The image analysis results are used to check whether, as shown in Figure 14C, the hand 6h of the winner 6W among the game participants 6 extends (moves) to the same placement area, and then all the game coins 9 disappear (the state in Figure 14D), thereby determining whether there is any cheating.

[0128] Furthermore, the control device 4 is configured to determine whether the amount of game coins paid by the dealer 5 to the winner is correct based on the amount placed by the winner 6W among the game participants 6. Specific examples are shown below. Regarding the position and total amount of the game coins 9 (which placement area 8 on the P side or B side is the game coin 9 placed in), it is conceivable that if the game coins 9 are staggered or overlapped, or fall into a blind spot from the position of the camera 2, they are usually not readable. The control device 14 is configured to use a computer or control system based on existing artificial intelligence, a self-learning function based on deep learning (construction) technology, etc., to identify the concealment of the game coins 9 due to blind spots (the case of partial concealment of a game coin, or the case of the game coin being completely concealed), and accurately grasp the position and number of coins. Furthermore, the structure for detecting the position 8 and type of the game coin 9 in the placement area 8 is not limited to this. For example, it can also be configured to detect by reading the ID embedded in the game coin.

[0129] As described above, the control device 14 can grasp the position 8 (position of the game coin 9 placed by P, B, or PAIR), type (game coin 9 is assigned a different value according to each color) and number of game coins 9 placed by each player 6 through the camera 2 and the image analysis device 12. It can detect which player 6 placed the game coin 9 to P (if there are multiple players 6 placed the game coin 9 to P, the player 6 who placed the highest value) and which player 6 placed the game coin 9 to B (if there are multiple players 6 placed the game coin 9 to B, the player 6 who placed the highest value).

[0130] Furthermore, the control device 14 of the cheat detection system of this game, according to the rules of a certain card game, analyzes the information obtained by the image analysis device 12 using the camera 2 through the above-described method, and performs monitoring. By performing the monitoring shown in 1) to 5) above, it determines whether cheating that violates the rules has been performed. When cheating is detected, the card dispensing detection device 14C activates the abnormal indicator lights 16 installed on both the card dispensing device 3 and the game table 4, and outputs the detection of cheating to the casino management department via wireless or wired transmission 15. It is also possible to further have monitors or lights in other locations to receive the judgment results and issue warnings or displays.

[0131] As described above, when cheating is detected by the control device 14, a display signal is sent to the indicator light 13 or abnormal indicator light 16 of the card dispensing device 3 at the time of detection or at an appropriate moment. However, in addition to issuing a warning, it is also possible to activate the card dispensing device 3's function of preventing card dispensing after the time of detection of cheating or error, thus preventing the dispensing of card 1.

[0132] Hereinafter, an embodiment of the card dispensing device 3 used in the table game system of the present invention will be described using Figures 15 to 19. The card dispensing device 3 includes: a card storage section 102 that stores a plurality of shuffled game cards 1s; a card guiding section 105 that guides the shuffled game cards 1 one by one manually drawn from the card storage section 102 by the dealer 5 or others; and an opening section 106 for removing the cards 1 guided by the card guiding section 105. The card detection unit (card detection sensors 22 and 23) detects the removal of the shuffled game cards 1; the card reading unit 108 reads information indicating the minimum number (card size) of the shuffled game cards 1; the control unit 109 determines the winner of the card game based on the number (card size) of the shuffled game cards 1 read sequentially by the card reading unit 108; the result display light 13 displays the winner determined by the control unit 109; the dispensing restriction device 30 is provided at the opening 106 to restrict the entry and exit of cards 1 into the card receiving section 102; and the management control unit 114 has the same functions as the control device 14. These are integrated and have the following functions: detecting errors by the dealer in the game by the control device 14. In the event of cheating, the card dispenser prevents cards from being drawn from the card dispenser 3 at a specified time after the point at which the error or cheating is detected.

[0133] Next, the dispensing restriction device 30 that restricts the entry and exit of cards 1 from the card receiving section 102 will be described using Figures 17 and 16. The dispensing restriction device 30 is provided on the card guide 107 of the card guide section 105, which guides cards 1 taken out one by one from the opening 106 at the front of the card receiving section 102 onto the game table 4. The dispensing restriction device 30 is configured such that when a card 1 passes through the slit 33 between the card guide section 105 and the guide cover of the card guide 107, the locking member 34 presses down on the card 1 to prevent the card 1 from entering or exiting the slit 33. The locking member 34 is driven by a solenoid or piezoelectric element, etc., and moves as shown by arrow m in a manner that allows the card 1 to be in a pressed position (restricted position) and a passable position that allows the card 1 to pass. The drive unit 35 is controlled by a control unit 109 that is directly or indirectly connected to the control device 14 via wired or wireless means, so that the locking member 34 moves between the two states of the pressed card 1 position and the passable position that allows the card 1 to pass. In the control unit 109, the rules of a certain card game are programmed and stored in advance.

[0134] Next, a variation of the dispensing restriction device 30 will be described with reference to FIG18B. The dispensing restriction device in the variationThe 40 has the following structure: when the card 1 passes through the slit 33 between the card guide 105 and the card guide 107 (guide cover), the locking member 36 protrudes into the slit 33 to prevent the card 1 from moving. The locking member 36 is driven by a drive unit 37, such as an electromagnetic solenoid or a piezoelectric element, to move in a manner that allows the card 1 to pass through, as shown by arrow m. The drive unit 37 is controlled by a control unit 109 connected to the control device 14 to move the locking member 36 between the two states of preventing the card 1 from moving and allowing the card 1 to pass through.

[0135] Next, the details of the code reading unit 108, which reads the code 52 representing the number (number, card size) of the card 1 from the card 1 when the card 1 is manually pulled out from the card storage unit 102, will be described. FIG17 is a top view of the main parts of the card dispensing device 3. In the figure, the code reading unit 108 is provided on the card guide unit 105, which guides the manually removed cards 1 one by one from the opening 106 at the front of the card receiving unit 102 onto the game table 4. The card guide unit 105 is an inclined surface, and card guides 107, which also serve as sensor covers, are installed on the edges on both sides. Moreover, each of the two card guides 107 can be installed and removed by screws or the like (not shown). If the card guides 107 are removed, the sensor group 115 of the code reading unit 108 is exposed. The sensor group 115 consists of four sensors, namely two ultraviolet sensing sensors (UV sensors) 20 and 21 and object detection sensors 22 and 23.

[0136] The object detection sensors 22 and 23 are fiber optic sensors that detect the presence or absence of cards 1 and can detect the movement of cards 1. Object detection sensor 22 is located upstream of card guide 105 along the moving direction of card 1, and another object detection sensor 23 is located downstream. As shown, the two object detection sensors 22 and 23 sandwich UV sensors 20 and 21 and are disposed on the upstream and downstream sides. UV sensors 20 and 21 are equipped with an LED (ultraviolet LED) that emits ultraviolet light and a detector. On card 1, the mark M of code 52 is printed with ultraviolet light luminescent ink that emits color when exposed to ultraviolet light. When ultraviolet light (near ultraviolet light) shines on card 1, the detector detects the reflected light of the mark M of code 52 on card 1. UV sensors 20 and 21 are connected to code reading unit 108 and control unit 109 via cables. In code reading unit 108, the combination of marks M is determined according to the output signal of the detector of UV sensors 20 and 21, and the number (card size) corresponding to each code 52 is determined.

[0137] For code reading unit 108, the control unit 109 controls the code reading unit 108 according to the detection signal of object detection sensors 22 and 23.The UV sensors 20 and 21 read the beginning and end of the reading. Furthermore, the control unit 109 determines whether card 1 has passed normally through the card guide unit 105 based on the detection signals from the object detection sensors 22 and 23. As shown in Figure 19, quadrilateral markers M, representing the card's face value (number) and suit (hearts or spades, etc.), are arranged in 2 columns and 4 rows along the edge of card 1. If the UV sensors 20 and 21 detect marker M, they output an ON signal. In the code reading unit 108, the relative relationship between the two signals input from the two UV sensors 20 and 21 is determined. Therefore, the code reading unit 108 determines the code based on the relative difference between the two markers M detected by the two UV sensors 20 and 21, thus determining the corresponding card 1's number (face value) and type (suit).

[0138] Figure 19 shows the relationship between code 52 and the outputs of the ON signals of the two UV sensors 20 and 21. Based on the comparison of the relative changes in the outputs of the ON signals of the UV sensors 20 and 21, the specified combination of marker M can be determined. As a result, if there are 4 combinations of marker M as the upper and lower columns, and they are printed in 4 columns, then 4 to the power of 4, a total of 256 codes, can be formed. The 52 types of game cards are assigned to one of the 256 codes, and stored as a lookup table in a memory or program. The code reading unit 108 is configured to determine the number (card size) and type (suit) of card 1 by determining each code 52 according to a pre-set lookup table (not shown). In addition, the 256 codes and 52 cards can be freely combined and stored in a lookup table, so the combination is complex and can vary with time and place. The code is preferably printed using a paint that is visible under ultraviolet light, and is printed in a position that does not overlap with the card type label and index 103.

[0139] Furthermore, in the above embodiment, the image analysis device 12 and the control device 14 are devices with artificial intelligence-efficient or deep learning structures. However, specifically, the image analysis device 12 and the control device 14 can perform image analysis and the various controls described above using scale-invariant feature transform (SIFT) algorithms, convolutional neural networks (CNNs), deep learning, machine learning, or similar methods. These techniques are techniques for image recognition of photographic images to identify objects contained within the images. In particular, in recent years, techniques have been developed that utilize multi-layered neural networks.Deep learning techniques are used to identify objects with high accuracy. These deep learning techniques generally identify objects with high accuracy by overlapping layers across multiple stages in the intermediate layers between the input and output layers of a neural network. In particular, convolutional neural networks have attracted attention because they have higher performance than object identification based on existing image feature quantities.

[0140] In a convolutional neural network, labeled object images are learned, and the main objects contained in the object images are identified. When there are multiple main objects in the learning image, a region rectangle is used to specify the region, and the image corresponding to the specified region is labeled and learned. Furthermore, in a convolutional neural network, it is also possible to determine the main objects in the image and the location of the objects.

[0141] If we further explain the convolutional neural network, in the object recognition process, by performing edge extraction processing on the object image, candidate regions are extracted based on local features. The candidate regions are then input into the convolutional neural network, and classification is performed based on the extracted feature vectors to obtain the candidate region with the highest confidence level as the recognition result. The so-called credibility is a measure of how much higher the similarity between a certain image region and the subject of the image learned along with the label is compared to other levels of similarity.

[0142] Furthermore, devices with artificial intelligence-efficient or deep learning structures are described in U.S. Patent No. 9,361,577, U.S. Patent Publication No. 2016-171,336, U.S. Publication No. 2015-036,920, and Japanese Patent Publication No. 2016-110,232, etc., and these descriptions are incorporated herein by reference.

[0143] Various embodiments of the present invention have been described above, but of course, those skilled in the art can modify the above embodiments within the scope of the present invention, and the device of this embodiment can be appropriately modified according to the needs of the applicable game.
