[0001] Divisional Application

[0002] This application is a divisional application of patent application filed on February 9, 2018, with application number 201880024746.2, entitled "Amusement Park Substitute Currency Tray, Tabletop Game Management System, Amusement Park Substitute Currency Tray System, and Amusement Park Substitute Currency Management Method".

[0003] Cross-Reference to Related Applications

[0004] This application claims the benefit of patent application number 2017-024424 filed in Japan on February 13, 2017, the contents of which are incorporated herein by reference. Technical Field

[0005] This invention relates to a game coin tray for holding game coins. Background Art

[0006] Currently, in amusement parks such as casinos, game coins are used for placing and repaying game coins. U.S. Patent No. 5,735,742 employs an automated settlement system that automatically monitors all transactions of game tokens in a casino. In this system, RF tags are embedded in the game tokens, and an electronic system including an antenna embedded in the game table reads these RF tags. An antenna is also located below the game token tray, and the RF tags of multiple game tokens within the tray are read together in a non-contact manner.

[0007] However, when reading the RF tags, because multiple RF tags are read using a single antenna, it is unknown where the multiple game tokens with the read RF tags are located within the reading area (e.g., the game token tray). Therefore, for example, during game settlement, when counterfeit cheating game tokens are mixed into the game token tray, it is known that counterfeit game tokens are present in the tray, but it is impossible to determine where the tokens originated or identify the user of the counterfeit tokens.

[0008] Furthermore, in a game coin tray with a double-layer tray structure consisting of an upper tray and a lower tray stacked together, if multiple game coins housed in the upper tray and multiple game coins housed in the lower tray are read together using RF tags, it is impossible to distinguish whether the read RF tags belong to game coins housed in the upper tray or game coins housed in the lower tray. That is, it is impossible to detect the movement of game coins between the upper and lower trays.

[0009] Moreover, in the method of reading RF tags together with multiple game coins, even if the multiple game coins include coins with malfunctioning RF tags or coins without built-in RF tags, this situation cannot be detected.

[0010] Furthermore, regarding the method of reading RF tags, RF tag reading errors may sometimes occur due to the angle or orientation of the game coins. In particular, for game coins housed at an angle in the game coin tray, it may be difficult to read the RF tags due to the angle problem.

[0011] Furthermore, regarding the method of reading RF tags, since the RF tags are read non-contactly by emitting radio waves from an antenna, prolonged exposure of the dealer and players to these radio waves may have adverse effects on their health.

[0012] The present invention was made in view of the above-mentioned problems, and its object is to provide a novel game coin tray system including a double-layer tray structure for holding game coins.

[0013] One embodiment of the game coin tray of the present invention is configured as follows:

[0014] A game coin tray, disposed on an amusement table for holding game coins, comprising:

[0015] an upper tray for placing or removing the game coins during game settlement;

[0016] a lower tray disposed below the upper tray for storing game coins replenished to the upper tray;

[0017] the game coin is structured as follows: forming a structure having a plastic layer, and at least a portion thereof having a specific color that can identify the type of game coin, having printed layers indicating the type of game coin applied to the top and bottom surfaces, having side codes that can be identified separately attached to the sides, and having an RF tag fixed to the plastic layer, the type of game coin being determined by the specific color;

[0018] The upper part of the upper tray forms an open structure, allowing the game coins placed on the upper tray to be photographed by a camera. The lower tray is configured to read the RF tags of the game coins placed on the lower tray using an RFID reader.

[0019] The upper tray and the lower tray are structures capable of having two states: an overlapping state; and an open state where game coins can be placed or removed from the lower tray.

[0020] The RFID reader is configured not to read the RF tags of the game coins placed on the upper tray when the upper tray and the lower tray are overlapping.

[0021] After each game, the dealer pays game coins to the players from the upper tray and collects the game coins collected from the players in the upper tray. Therefore, the number of game coins collected in the upper tray changes (increases or decreases) for each game. Therefore, it is desirable to be able to monitor whether the increase or decrease of game coins collected in the upper tray for each game is correct. Based on the above structure, the frequent changes in game coins in the upper tray, as described above, can be monitored based on tray image data.

[0022] Furthermore, when the number of game coins in the upper tray increases to the point that it cannot be accommodated, the dealer moves multiple game coins (e.g., in units of 100) from the upper tray to the lower tray. Conversely, when the game coins in the upper tray are used up, multiple (e.g., in units of 100) game coins are moved to the lower tray.For example, game coins (in units of 100) are moved from the lower tray to the upper tray. In this way, the game coins in the lower tray are not changed (added or removed) as frequently as those in the upper tray (e.g., approximately several times during a day's business hours). Therefore, it is desirable to confirm that a predetermined number of game coins are always present in the lower tray. According to the above structure, the presence of game coins stored in the lower tray and not visible from the outside can also be determined by reading tag information from the RF tag.

[0023] That is, according to the above structure, by using a camera to photograph the upper tray used for placing or removing game coins during game settlement, the position and movement of the game coins can be confirmed, thereby detecting cheating. For the lower tray storing replenished game coins, the RF tag can be read even when the upper tray is stacked, and the RF tags of the game coins in the upper tray are not read. Therefore, the game coins stored in the lower tray can be determined by reading the RF tag. In this way, the movement of game coins between the upper and lower trays can be monitored separately. Therefore, the movement of game coins between the upper and lower trays can also be monitored, and cheating during movement can be detected. In addition, for the upper tray, game coins with damaged RF tags and game coins missing RF tags can also be detected.

[0024] The above-mentioned game coin tray can also determine the position of the side code of each game coin in the upper tray by determining the side code.

[0025] According to this structure, it is possible to determine which game coin is located in which position on the upper tray.

[0026] In the above-mentioned game coin tray, the side code of the game coin can be printed using ink that is invisible to visible light.

[0027] According to this structure, it is not easy to counterfeit, and the security is further improved. At the same time, it can ensure the freedom of design of the side (visible under visible light) of the game coin.

[0028] In the above-mentioned game coin tray, the side code can be printed using ink that absorbs infrared light.

[0029] According to this structure, it is not easy to counterfeit, and the security is further improved. At the same time, it can ensure the freedom of design for the side (visible under visible light) of the game coin, and the side code can be captured by an infrared camera.

[0030] In the above-mentioned game coin tray, multiple lines of the side code can be set on the side.

[0031] According to this structure, the visibility of the side code of the camera can be improved, and the circumferential length of each side code can be shortened. Alternatively, more complex codes can be prepared within the same circumferential length.

[0032] The above-mentioned game coin tray can further include: a database that associates the side code of each of the multiple game coins with the tag information stored in the RF tag.

[0033] According to this structure, it can be determined by referring to the database whether the side code of the game coin corresponds to the tag information of the RF tag.

[0034] In the above-mentioned game coin tray, the game coins can be configured such that light-colored layers are provided on both sides in a manner that clamps the specific color layer.

[0035] According to this structure, the specific color layer is clamped by the light-colored layer, so when multiple game coins are stacked and then viewed from the side, the specific color layers of adjacent game coins are not continuous, thereby accurately determining the number of game coins.

[0036] One aspect of the management system of the present invention is a game management system using an arcade table, the management system comprising: game coins having the following structure: formed as a structure having a plastic layer, and at least a portion having a specific color that can determine the type of game coin, having printed layers indicating the type of game coin applied to the top and bottom surfaces, having side codes that can be identified separately attached to the sides, and having RF tags fixed to the plastic layer, the type of game coin being able to be determined by the specific color; a game coin tray, the game coin tray being disposed on the arcade table for holding the game coins; a camera for photographing and recording the game coins placed on the game coin tray; and an RFID reading device. The RFID reader reads the RF tags of the game coins placed in the game coin tray; and a management and control device uses the camera's capture results and the RFID reader's read results to determine and store the type and number of game coins on the game coin tray. The game coin tray has: an upper tray for placing or removing game coins during game settlement; and a lower tray disposed below the upper tray for storing game substitutes used to replenish the upper tray. The upper and lower trays can have two states: an overlapping state; and an open state where game coins can be placed or removed from the lower tray. Moreover, the upper part of the upper tray has an open structure so that the camera can capture images of the game coins placed on the upper tray. The lower tray is configured to allow the RFID reader to read the RF tags of the game coins placed on the lower tray.

[0037] According to this structure, by using a camera to photograph the upper tray used for inserting or removing game coins during game settlement, the position and movement of game coins can be confirmed, and cheating can be detected. For the lower tray storing game coins for replenishment, the RF tag can be read even when the upper tray is stacked on top of it. Therefore, the game coins stored in the lower tray can be identified by reading the RF tag. Furthermore, for the upper tray, game coins with damaged RF tags and game coins missing RF tags can also be detected.

[0038] In the above-described management system, the management control device can also determine the position of the side code of each game coin in the upper tray by determining the side code. Specification 3 / 25 pages 7 CN 120932337 A

[0039] According to this structure, it is possible to determine which game coin is located in which position on the upper tray.

[0040] In the above-described management system, the RFID reading device can be configured such that, when the upper tray and the lower tray overlap, it does not read the RF tag of the game coin placed on the upper tray.

[0041] According to this structure, the RF tag of the game coin on the upper tray is not read; therefore, the game coins on the upper tray and the game coins on the lower tray can be monitored separately, and the movement of the game coins between the upper tray and the lower tray can also be monitored.

[0042] The above-described management system may further include: a database that associates the side code of each of the multiple game coins with the RFID tag.

[0043] According to this structure, it is possible to determine whether the side code of the game coin corresponds to the tag information of the RF tag by referring to the database.

[0044] In the above-described management system, the side code can be printed using ink that is invisible to visible light.

[0045] According to this structure, it is not easy to counterfeit, and the security is further improved. At the same time, it can ensure the freedom of design for the side (visible under visible light) of the game coin.

[0046] In the above-described management system, the side code can be printed using infrared-absorbing ink.

[0047] According to this structure, it is not easy to counterfeit, and the security is further improved. At the same time, the design freedom of the side (visible under visible light) of the game coin can be ensured, and the side code can be captured by an infrared camera.

[0048] In the above-described management system, multiple lines of the side code can be set on the side.

[0049] According to this structure, the visibility of the side code can be improved, and the circumferential length of each side code can be shortened, or a more complex code can be prepared within the same circumferential length.

[0050] In the above-described management system, the game coin can be configured to have light-colored layers set on both sides in a manner that clamps the specific color layer.

[0051] According to this structure, the visibility of the side code by the camera can be improved.

[0052] The above-described management system can be configured such that when the side code is different from a pre-registered side code, the management control device can determine that it is a cheating game coin.

[0053] According to this structure, cheating game coins that do not have the correct side code can be detected.

[0054] In the above-described management system, the management control device can output a judgment result when it determines that the cheating game coins collected by the dealer of the game table from the upper tray, and use the camera to replay the recording of the cheating game coins.

[0055] According to this structure, the recording of the cheating game coins can be replayed to analyze cheating behavior.

[0056] In the above-described management system, the management control device can use the camera to determine where the game coins collected by the dealer of the game table and placed on the upper tray come from on the game table, and can use the camera to determine where the cheating game coins come from on the game table.The camera replays the recordings of the game coin movement.

[0057] Based on this structure, the user of the cheating game coin and their location can be determined.

[0058] In the above-mentioned management system, the camera can also photograph the banknotes used to purchase the game coins. The management control device has the following structure: it can use the photographing results of the banknotes to determine the type and number of game coins on the upper tray that should be reduced due to the purchase of game coins on the game coin tray with banknotes, and compare and measure them with the actual total amount of game coins on the game coin tray.

[0059] Based on this structure, it can be determined whether the purchase of game coins with banknotes is correct.

[0060] In the above-described management system, the management control device can compare and judge the following situations: whether the total amount of game coins held in the game coin tray corresponds to a reduction in the payment amount of game coins corresponding to the purchased paper money after purchasing the game coins with paper money; and whether it corresponds to the increase or decrease of game coins calculated based on the amount of game coins placed by all players and the winning or losing result of the game.

[0061] According to this structure, when purchasing game coins with paper money and settling the game, it can be determined whether the purchase and settlement are performed correctly.

[0062] In the above-described management system, the management control device can be an artificial intelligence effective utilization type or deep learning structure, which can obtain the information of the type and number of game coins even if part or all of them are hidden due to the blind spot of the camera when determining the type and number of game coins.

[0063] According to this structure, even for game coins randomly placed on the game table, the number and type can be identified based on the camera image.

[0064] In the above-described management system, the game coin has the following structure: the side code can be attached at least three times at intervals in the rotation direction of the light-colored layer on the side. By reading the side code using the camera, the type and manufacturing information of the game coin can be determined, and the determined information can be compared with a specified database for management.

[0065] According to this structure, the content of the side code representing the type and manufacturing information can be compared with the database to detect cheating game coins.

[0066] The above-described management system may further include: a camera that photographs and records the game coins on the game table. The camera is configured to photograph the game coins using a single camera or multiple cameras at different heights configured in specified positions.

[0067] According to this structure, game coins at various positions on the game table can be photographed from various angles.

[0068] One aspect of the present invention is a game coin tray, which is set on a game table for holding game coins.The coin tray comprises: an upper tray for placing or removing game coins during game settlement; and a lower tray disposed below the upper tray for storing game coins replenished to the upper tray. The game coins are formed as a structure having a plastic layer, at least a portion of which has a specific color to identify the type of game coin. Printed layers indicating the type of game coin are applied to both the upper and lower surfaces, allowing for individual value determination via the specific color. An RF tag indicating the value is fixed to the plastic layer. The upper portion of the upper tray is open, allowing for photographing of the game coins placed on it using a camera. The lower tray can read the RF tags of the game coins placed on it using an RFID reader. The upper and lower trays are configured to have two states: an overlapping state; and an open state where game coins can be placed or removed from the lower tray. When the upper and lower trays are overlapping, the RFID reader does not read the RF tags of the game coins placed on the upper tray.

[0069] According to this configuration, by using a camera to photograph the upper tray used for placing or removing game coins during game settlement, the position and movement of the game coins can be confirmed, and cheating can be detected. Regarding the lower tray for storing replenished game coins, the RF tag can be read even when the upper tray is stacked on top of it, and the RF tag of the game coins on the upper tray will not be read. Therefore, the game coins stored in the lower tray can be monitored by reading the RF tag. In this way, the game coins on the upper tray and the game coins on the lower tray can be monitored separately. Therefore, the movement of game coins between the upper tray and the lower tray can also be monitored, and cheating during movement can be detected. In addition, regarding the upper tray, game coins with damaged RF tags and game coins missing RF tags can also be detected.

[0070] In the above-mentioned game coin tray, the number of game coins in each position on the upper tray can be determined by determining the value of the game coins. Instruction manual 5 / 25 page 9 CN 120932337 A

[0071] According to this structure, it is possible to determine how many game tokens of what value are located in which position on the upper tray.

[0072] One aspect of the present invention is a management system for a game using an arcade table, the management system comprising: game tokens having the following configuration: formed as a structure having a plastic layer, at least a portion having a specific color that can determine the type of game token, printed layers indicating the type of game token applied on the upper and lower surfaces, the value being individually determined by the specific color, and an RF tag indicating the type fixed on the plastic layer; gameThe game coin tray is disposed on the game table to hold the game coins; a camera is used to photograph the game coins placed on the game coin tray; an RFID reader is used to read the RF tags of the game coins placed on the game coin tray; and a management and control device is used to determine and store the value and number of game coins on the game coin tray using the results of the camera's image and the RFID reader's image. The game coin tray has: an upper tray for placing or removing game coins during game settlement; and a lower tray disposed below the upper tray for storing game coins used to replenish the upper tray. The upper and lower trays can have two states: an overlapping state; and an open state where game coins can be placed or removed from the lower tray. Moreover, the upper part of the upper tray has an open structure to allow the camera to photograph the game coins placed on the upper tray, and the lower tray can be read by the RFID reader.

[0073] According to this structure, by using a camera to photograph the upper tray used for placing or removing game coins during game settlement, the position and movement of game coins can be confirmed, and cheating can be detected. For the lower tray storing replenished game coins, even when the upper tray is stacked, the RF tag can be read. Therefore, the game coins stored in the lower tray can be identified by reading the RF tag. Furthermore, regarding the upper tray, game coins with damaged RF tags or missing RF tags can be detected.

[0074] In the above-described management system, the management control device can use the camera to determine the value and position of each game coin on the upper tray.

[0075] According to this structure, it is possible to determine which value of game coins is located in which position on the upper tray.

[0076] In the above-described management system, the management control device can use the camera to determine whether the game coins in the upper tray are predetermined game coins.

[0077] According to this structure, cheating game coins can be identified.

[0078] One aspect of the game coin tray system of the present invention has the following configuration: it comprises: a double-layer tray, which consists of a lower tray and an upper tray stacked on the lower tray, for holding game coins equipped with RF tags, the RF tags storing tag information; an image acquisition mechanism for photographing the game coins held in the upper tray to acquire tray image data; an RFID reading mechanism for reading the tag information from the RF tags of the game coins held in the lower tray; and a recording mechanism for recording the received...The game coins contained in the upper tray are recorded with tray image data and / or image analysis results of the tray image data. Simultaneously, for the game coins contained in the lower tray, the tag information read by the RFID reader is recorded.

[0079] According to this structure, for the upper tray, tray image data can be acquired, thereby confirming the position and movement of the game coins and detecting cheating. For the lower tray, even when the upper tray is stacked, the RF tag can be read, thereby identifying the contained game coins. Furthermore, regarding the upper tray, game coins with damaged RF tags and game coins missing RF tags can also be detected.

[0080] In the above-described game coin tray system, the image acquisition mechanism may be configured not to photograph the game coins contained in the lower tray, the RFID reading mechanism may be configured not to read the tag information of the game coins contained in the upper tray, and the recording mechanism may not record the tag information of the game coins contained in the upper tray, nor record the tray image data of the game coins contained in the lower tray, nor the image analysis results of the tray image data.

[0081] According to this structure, the RF tags of the game coins in the upper tray are not read. Therefore, the game coins in the upper tray and the game coins in the lower tray can be monitored separately, and the movement of the game coins between the upper and lower trays can also be monitored.

[0082] In the above-described game coin tray system, the game coins contained in the lower tray can be positioned in a location not captured by the image acquisition mechanism. The RFID reading mechanism can be configured not to read the tag information of the game coins contained in the upper tray. The recording mechanism can not record the tag information of the game coins contained in the upper tray, nor record the tray image data of the game coins contained in the lower tray, nor the image analysis results of the tray image data.

[0083] According to this structure, the RF tags of the game coins in the upper tray are not read. Therefore, the game coins in the upper tray and the game coins in the lower tray can be monitored separately, and the movement of the game coins between the upper and lower trays can also be monitored.

[0084] The above-described game coin tray system may further include: an image analysis mechanism that determines the position of the game coins contained in the upper tray based on the tray image data, and the recording mechanism can record the position information of the game coins as the image analysis result.

[0085] According to this structure, the position of the game coins in the upper tray can be determined and recorded.

[0086] In the above-described game coin tray system, an indicator representing the value of the game coin can be attached to the side of the game coin.The system may further include: an image analysis mechanism that determines the value represented by the color of the side of the game coin contained in the upper tray based on the tray image data, and a recording mechanism that records the value determined by the image analysis mechanism as the image analysis result.

[0087] According to this structure, the value of the game coin in the upper tray can be determined and recorded by the color of its side.

[0088] In the above game coin tray system, the identification information of the game coin can be marked on the side of the game coin.

[0089] The system may further include: an image analysis mechanism that determines the identification information of the game coin contained in the upper tray based on the tray image data,

[0090] and a recording mechanism that records the identification information determined by the image analysis mechanism as the image analysis result.

[0091] According to this structure, the type of game coin in the upper tray can be determined and recorded by the identification information marked on its side.

[0092] The above game coin tray system may further include: a database that records the identification information.

[0093] According to this configuration, cheating game coins can be detected by comparing the identification information marked on the side with a database.

[0094] In the above-described game coin tray system, the image analysis mechanism can perform machine learning-based image recognition on the tray image data.

[0095] According to this configuration, the tray image data can be analyzed with high precision.

[0096] The above-described game coin tray system may further include: a cheat detection mechanism that detects cheating based on the image analysis results. Specification 7 / 25 pages 11 CN 120932337 A

[0097] According to this structure, cheating detection can be performed based on the image analysis results.

[0098] The above-described game coin tray system may further include: a cheat detection mechanism that detects cheating based on the image analysis results and the tag information read from the RF tag.

[0099] According to this structure, cheating detection can be performed based on the image analysis results and the read tag information.

[0100] One aspect of the game coin tray system of the present invention is based on the following configuration: it comprises: a double-layer tray, which consists of a lower tray and an upper tray stacked on the lower tray, for holding game coins equipped with RF tags, the RF tags storing tag information; an image acquisition mechanism that photographs the game coins held in the upper tray to acquire tray image data; an RFID reading mechanism that reads the tag information from the RF tags of the game coins held in the lower tray; and a cheat detection mechanism that detects cheating...The mechanism detects cheating on the upper tray based on the tray image data and on the lower tray based on the tag information read by the RFID reader.

[0101] According to this structure, cheating can be detected on the upper tray based on the tray image data. For the lower tray, even when the upper tray is stacked, the RF tag can be read. Therefore, the game coins stored in the lower tray can be identified by reading the tag information. In addition, for the upper tray, game coins with damaged RF tags and game coins missing RF tags can also be detected.

[0102] In the above-described game coin tray system, a color representing the value of the game coin can be attached to the side of the game coin. The RF tag can store information representing the value of the game coin. As the tag information, it can further include: an image analysis mechanism, which determines the value represented by the color of the side of the game coin contained in the upper tray based on the tray image data. When the game coin moves between the upper tray and the lower tray, the cheating detection mechanism can determine whether the value added or subtracted in the upper tray corresponds to the value added or subtracted in the lower tray based on the value determined by the image analysis mechanism and the value read by the RFID reading mechanism, thereby detecting cheating.

[0103] According to this structure, it can be determined whether the movement of the game coin between the upper tray and the lower tray is correct.

[0104] In the above-described game coin tray system, a color representing the value of the game coin can be added to the side of the game coin. The system may further include an image analysis mechanism that determines the value represented by the color of the side of the game coin contained in the upper tray based on the tray image data. The cheat detection mechanism can determine whether the settlement amount before and after settlement corresponds to the value increased or decreased in the upper tray based on the value determined by the image analysis mechanism and the settlement amount based on the game result and the player's placement, thereby detecting cheating.

[0105] According to this structure, it can be determined whether the settlement was performed correctly after the game ended.

[0106] In the above-described game coin tray system, as the tag information, the RF tag of the game coin can store the identification information of the game coin, and the identification information of the game coin can be marked on the side of the game coin. It can further include: an image analysis mechanism that determines the identification information of the game coin contained in the upper tray based on the tray image data. When the game coin moves between the upper tray and the lower tray, the cheating detection mechanism can detect cheating by judging whether the identification information read by the RFID reader corresponds to the identification information determined based on the tray image data.

[0107] According to this structure, cheating can be detected when game coins move between the upper and lower trays using identification information.

[0108] In the above-described game coin tray system, the identification information of the game coin can be marked on the side of the game coin, and it can further include: an image analysis mechanism that determines the identification information of the game coin contained in the upper tray based on the tray image data; a database that stores multiple pieces of the identification information, and the cheating detection mechanism can determine whether the identification information determined by the image analysis mechanism is stored in the database to determine cheating.

[0109] According to this structure, game coins that are not marked with the identification information stored in the database can be detected as cheating game coins.

[0110] In the above-described game coin tray system, the cheating detection mechanism can determine the location of cheating game coins whose identification information determined by the image analysis mechanism is not stored in the database.

[0111] According to this structure, the location of cheating game coins can be determined.

[0112] In the above-described game coin tray system, the double-layer tray can be set on the game table. The image acquisition mechanism can further photograph the tabletop and acquire tabletop image data. The cheating detection mechanism determines from where on the tabletop the cheating game coin was retrieved based on the location of the cheating game coin and the tabletop image data.

[0113] According to this structure, it is possible to determine where the cheating game coin came from (which player or the player's location).

[0114] In the above-described game coin tray system, the double-layer tray can be set on the game table. Information indicating the value of the game coin can be marked on the side of the game coin. The image acquisition mechanism can photograph the tabletop and acquire tabletop image data. It can further include: an image analysis mechanism that determines the amount of banknotes used to purchase the game coin based on the tabletop image data, and determines the value based on the image of the side of the game coin contained in the upper tray. The cheating detection mechanism can determine whether the amount of banknotes determined by the tabletop image analysis mechanism corresponds to the value of the game coin purchased with the banknotes.

[0115] According to this structure, when purchasing game tokens with banknotes at an arcade table, it can be determined whether the purchase is equivalent and whether the purchase is made correctly.

[0116] One aspect of the game token tray system of the present invention has the following structure: it comprises a double-layer tray, which consists of a lower tray and an upper tray stacked on the lower tray, for storing game tokens equipped with RF tags, the RF tags storing tag information; a tray image acquisition mechanism, which captures images of the game tokens stored on the upper tray.The game coins in the tray are photographed to obtain tray image data; the RFID reading mechanism is configured to read the tag information from the RF tag of the game coins contained in the lower tray, but not from the RF tag of the game coins contained in the upper tray.

[0117] According to this structure, the tray image data of the game coins in the upper tray can be obtained, and the RF tag of the game coins in the lower tray can be read. However, the RF tag of the game coins in the upper tray is not read. Therefore, the game coins contained in the lower tray can be identified by reading the RF tag.

[0118] One aspect of the present invention is a game coin tray system having the following structure: comprising: a double-layer tray, the double-layer tray being composed of a lower tray and an upper tray stacked on the lower tray, for accommodating game coins equipped with RF tags, the RF tags storing tag information; an RFID reader configured to read the tag information from the RF tags of the game coins accommodated in the lower tray, but not from the RF tags of the game coins accommodated in the upper tray; and a cheat detection mechanism that detects cheating movement of the game coins based on the tag information read by the RFID reader when the game coins move between the upper tray and the lower tray.

[0119] According to this structure, the tray image data of the game coins on the upper tray can be obtained, and the RF tag of the game coins on the lower tray can be read. Therefore, the movement of game coins between the upper and lower trays can be monitored, and cheating can be detected, such as the extraction of game coins during the movement. (See page 9 / 25 of the specification, CN 120932337 A)

[0120] One aspect of the present invention is a game coin management method for storing game coins in a double-layer tray consisting of a lower tray and an upper tray stacked on the lower tray. The method includes: a tray image acquisition step, which captures an image of the game coins stored in the upper tray to acquire tray image data; an image analysis step, which analyzes the game coins stored in the upper tray by performing image analysis on the tray image data; a reading step, which reads the tag information from the RF tag of the game coins stored in the lower tray; and a cheating movement detection step, which determines whether an increase or decrease in the game coins in the upper tray based on the tray image data corresponds to an increase or decrease in the game coins in the lower tray based on the tag information read in the reading step, thereby detecting cheating movement of the game coins.

[0121] According to this structure, the tray image data of the game coins in the upper tray can be read, and the image data of the game coins in the lower tray can be read.The RF tag of the game coin allows for monitoring the movement of the game coin between the upper and lower trays, enabling the detection of cheating, such as removing the game coin during the movement.

[0122] In the above game coin management method, the value of the game coin can be marked on its side. The image analysis step can determine the value of the game coin contained in the upper tray by performing image analysis on the tray image data. The game coin management method can further include: a settlement amount calculation step, which calculates the settlement amount of the game coin based on the game result and the player's placement amount; and a cheat settlement detection step, which determines whether the settlement amount calculated in the settlement amount calculation step corresponds to the value added or subtracted in the upper tray, thereby detecting cheat settlement.

[0123] Based on this structure, it can be determined whether settlement was performed correctly.

[0124] In the above game coin management method, the image analysis in the tray image analysis step can be image recognition based on machine learning.

[0125] Based on this structure, the accuracy of cheat detection can be improved.

[0126] Effects of the Invention

[0127] According to the present invention, by using a camera to photograph the upper tray used for placing or removing game coins during game settlement, the position and movement of game coins can be confirmed, thereby detecting cheating. For the lower tray used to store replenished game coins, the RF tag can be read even when the upper tray is stacked on top of it. Furthermore, since it is constructed not to read the RF tags of the game coins on the upper tray, the game coins stored in the lower tray can be monitored by reading the RF tags. In this way, the game coins on the upper tray and the game coins on the lower tray can be monitored separately, and the movement of game coins between the upper and lower trays can also be monitored, thus detecting cheating during this movement. In addition, for the upper tray, game coins with damaged RF tags and game coins with missing RF tags can also be detected.

[0149] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that the embodiments described below are examples of implementing the present invention, and the present invention is not limited to the specific structures described below. When implementing the present invention, appropriate specific structures may also be adopted according to the embodiments.

[0150] The game coin tray system in an amusement park with multiple game tables and the management system for tabletop games in the first embodiment of the present invention will be described. The management system of this embodiment includes a game table and a game coin tray system, and the game coin system of this embodiment includes game coins, game coin trays, cameras, RFID reading devices, management and control devices, etc.

[0151] First, the game coins used in the management system and even the game coin tray system of this embodiment will be described. Figure 1 is a side view of the game coins in this embodiment, and Figure 2 is a cross-sectional view of the game coins in this embodiment. As shown in Figure 1, the game coin 120 is formed by stacking multiple layers of plastic of different colors. The game coin 120 has a multi-layered structure, that is, at least in the middle, there is a layer (specific color layer) 121 with a specific color, and on both sides of the specific color 121, light-colored layers (light-colored layers) 122 are stacked. It should be noted that the color of the light-colored layer 122 only needs to be lighter than the specific color (higher brightness), including white.

[0152] When manufacturing the game coin 120, after stacking multiple plastic sheets and hot-pressing them together, a stamping process is performed.This yields multiple game coins 120. Specifically, firstly, a light-colored plastic sheet serving as the lower light-colored layer 122, a plastic sheet of a specific color serving as the specific color layer 122, and a plastic sheet serving as the upper light-colored layer 122 are sequentially stacked to form a stacked structure composed of multiple plastic layers. At this time, a wireless tag, i.e., an RF tag (RF game coin, also known as a contactless tag) 125 is embedded at approximately the center of each stamping process used to prepare the multiple game coins 120. Specifically, the RF tag 125 is placed between the specific color layer 121 and the upper light-colored layer 122.

[0153] Patterns corresponding to each game coin 120 are printed on the top and bottom of the stacked structure, and a transparent layer 124 is provided thereon. Then, the stacked structure and each layer of the transparent layer 124 are heat-pressed together to heat-melt each layer, thereby producing a substitute coin base plate. At this time, regarding the part overlapping with the RF tag 125, due to the heat effect, the plastic sheet deforms corresponding to the RF tag 125 (in addition, in FIG2, the thickness of the RF tag 125 drawn is greater than the actual thickness, and it is actually thinner than the specification 11 / 25 page 15 CN 120932337 A), therefore, the top and bottom of the game coin 120 after the devices are heat-pressed together will not bulge due to the RF tag 125, but will be formed as a flat shape.

[0154] The game coin original plate made in this way is stamped by a mold to obtain a plurality of game coins 120 of a specified shape. During this stamping process, the upper and lower corners of the outer side of the game coin 120 are R-processed by the mold.

[0155] By making the game coin 120 into a multi-layer structure formed by stacking a specific color layer 121 and a light color layer 122, as shown in FIG2, stripes formed on the side by the specific color layer 121 being sandwiched by the light color layer 122 in the stacking direction are formed. Here, the specific color can be different depending on the type of game coin 120 (i.e., value: 10 points, 20 points, 100 points, 1000 points, etc.). For example, 10 points can be set to red, 20 points to green, 100 points to yellow, and 1000 points to blue. The color of the light-colored layer 122 can be used for all types of game coins 120. That is, the color of the light-colored layer 122 is the same for any type of game coin 120.

[0156] Accordingly, the game coin 120 has the following configuration, that is, it has at least a specific color layer 121 and a light-colored layer 122 in appearance, so as to form axial (thickness direction) stripes on the side, and the type of game coin 120 can be determined by the color of the specific color layer 121. Thus, even when multiple game coins 120 are stacked, their type can be determined by observing their side and by the color of the specific color layer 121 sandwiched by the light-colored layer 122.

[0157] As tag information, the RF tag 125 stores at least the unique identification information of the game coin 120, and the game coin itself.The type (value), manufacturing date, etc. of the game coin 120. In a regular game coin 120, the type (value) stored in the RF tag 125 as tag information is consistent with the type (value) represented by the specific color layer 121 on the side.

[0158] Figures 3 to 5 are cross-sectional views of other embodiments of the game coin. In Figure 3, the specific color layer 121 is composed of three layers. The middle layer of the specific color layer 121 has a hole B for receiving the RF tag 125 formed in its center. The hole B is sandwiched between the upper and lower layers of the specific color layer 121, thereby forming a cavity for receiving the RF tag 125.

[0159] Figure 4 shows an example of forming the specific color portion 121 and the white portion 122 by injection molding. Specifically, it is prepared by so-called two-color molding, that is, firstly, the specific color portion 121 is formed in the molding die (not shown) using a specific color resin, and then, the light color portion 122 is formed using a light color resin.

[0160] FIG5 shows an example of forming the game coin 120 using a light-colored resin or even plastic material, and then printing a specific color on the center of the side, thereby realizing a specific color layer sandwiched by a light-colored layer. In this case, the game coin 120 can be embedded with an RF label 125 between two sheets made of light-colored plastic, and then the top and bottom are printed, followed by the overlay of a transparent layer 124, the laminated body is hot-pressed together, stamped, and then the side is colored with a specific color.

[0161] Next, the game coin tray will be described. FIG6 is a plan view of the game coin tray, and FIG7 is a side view of the game coin tray. The game coin tray 17 of this embodiment has a double-layer tray structure consisting of an upper tray 171 and a lower tray 172. The game coin tray 17 holds the game coin 120 by the upper tray 171 and the lower tray 172 respectively. As shown in FIG7, the upper tray 17 is used by stacking on the lower tray 172.

[0162] The lower tray 172 is disposed below the upper tray 171 and is used to store game coins 120 used to replenish the upper tray 171. Furthermore, the lower tray 172 is also used to accommodate game coins 120 that cannot be accommodated in the upper tray 171. During the game, the upper tray 171 is stacked on top of the lower tray 172 and is used to place or remove game coins 120 during game settlement. Therefore, the top of the upper tray 171 is open. Alternatively, the upper tray 171 can be removed from above the lower tray 172 to open the top of the lower tray 172, thereby allowing game coins 120 to be placed or removed.

[0163] As shown in FIG6, the upper tray 171 has multiple vertical storage sections 173 and one horizontal storage section 174 located above it. During settlement, game coins 120 are paid to the player from the vertical storage sections 173, and the game coins 120 recovered from the player are temporarily stored in the horizontal storage section 174. The lower tray 172 has multiple rows of longitudinal receiving sections 175.

[0164] An antenna 176 is disposed below the lower tray 172. This antenna 176 is used to read the RF tag 125 of the game coin 120 stored in the lower tray 172 (page 12 / 25 of the instruction manual, CN 120932337 A). The antenna 176 is connected to a reader 177, and the RFID reading device 170 consists of the antenna 176 and the reader 177. The antenna 176 is controlled by the reader 177 to generate radio waves. The RF tag 125 of the game coin 120 stored in the lower tray 172 receives these radio waves and generates power through rectification, transmitting the information stored in the RF tag 125 (tag information) along with the radio waves. The antenna 176 receives these radio waves, and the reader 177 reads the tag information stored in the RF tag 125 from these radio waves.

[0165] Here, the RFID reading device 170, consisting of the antenna 176 and the reader 177, is configured such that radio waves only reach the RF tags 125 inside the game coins 120 in the lower tray 172. Therefore, tag information is read from the RF tags 125 of the game coins 120 housed in the lower tray 172, but not from the RF tags 125 of the game coins 120 housed in the upper tray 171. This structure can be achieved by adjusting the frequency and intensity of the radio waves transmitted from the antenna 176, the materials of the lower tray 172 and the upper tray 171, and the position of the antenna 176. It should be noted that the RFID reading device 170 can also read the tag information of the RF tags 125 by electromagnetic induction.

[0166] FIG8 is a plan view showing the state after the upper tray 171 is removed (open state). If the upper tray 171 is removed, the top of the lower tray 172 is exposed, and the game coins 120 can be placed in or taken out of the lower tray 172. The upper tray 171 and the lower tray 172 are connected by a chain 178. Thus, the coin tray 17, consisting of the upper tray 171 and the lower tray 172, can have two states: an overlapping state where the upper tray 171 and the lower tray 172 overlap each other; and an open state where coins 120 can be placed or removed from the lower tray 172.

[0167] Figures 9 and 10 are side views showing other examples of the coin tray 17. In this example, the coin tray 17 is also configured as a double-layered tray consisting of an upper tray 171 and a lower tray 172. However, in this example, the upper tray 171 and the lower tray 172 are connected by two equal-length connecting rods 179a and 179b. As shown in Figure 10, the upper tray 171 can be lifted diagonally upwards while remaining parallel to the lower tray 172.

[0168] When the game coin 120 is placed in or removed from the lower tray 172, the upper tray 171 is moved via the connecting rods 179a and 179b, forming the state shown in Figure 10. This structure prevents the game coin 120 contained in the upper tray 171 from spilling out.The top of the lower tray 172 can be opened. In the state shown in FIG. 9, the upper tray 171 can be photographed by the camera 2.

[0169] Next, the management system of the game table including the game coin 120 and the game coin tray 17 will be described. FIG. 11 is a diagram showing the overall outline of the management system of this embodiment. The management system 100 uses the management control device 15 to manage the table games on each game table in an amusement park with multiple game tables 4. Each game table is equipped with the management system 100. FIG. 11 shows the game table 4 and the management control device 15. Multiple game tables 4 in the amusement park can also share the management control device 15.

[0170] One side of the game table 4 (the upper part of FIG. 11) is straight, and its opposite side (the lower part of FIG. 11) is curved. The dealer 5 located on the straight side is opposite to multiple players located on the curved side. Each player on the game table 4 has a separate placement area 8 for each player, and the dealer 5 has a game coin tray 17 in front of him. The coin tray 17 is embedded in the game table 4 with the upper tray 171 protruding from the tabletop of the game table 4.

[0171] The management system 100 includes multiple cameras 2 mainly used for capturing images of the tabletop of the game table 4 (and the coin tray, hands, etc. on the tabletop). Two cameras 2 are shown in FIG11, but the actual configuration of the cameras 2 is not limited to this.

[0172] FIG12 is a diagram showing an example configuration of the multiple cameras 2 in the management system 100. In this example, as cameras 2, the management system 100 includes: camera 2L, which is located at the upper left of the game table 4 and mainly captures images of the right side of the game table 4; camera 2R, which is located at the upper right of the game table 4 and mainly captures images of the left side of the game table 4; camera 2C, which mainly captures images of the coin tray 17 from above; and camera 2P, which mainly captures images of the coin tray 17 from a slightly upward angle.

[0173] With the above configuration, multiple cameras 2 capture the game being played on the game table 4 and generate image data (video data or still image data). Multiple cameras 2 can also capture the player 6 or the dealer 5's actions with the card C or game coin 120. The aforementioned multiple cameras 2 are equivalent to the image acquisition mechanism of this invention.

[0174] It should be noted that cameras 2C and 2P, which capture the game coin tray 17, are both configured to capture the game coins 120 housed in the upper tray 171. When the upper tray 171 is stacked on top of the lower tray 172, cameras 2C and 2P cannot capture the lower tray 172. Furthermore, camera 2P captures the upper tray 171 from an oblique angle, since the lower tray 172 is embedded in the game table 4.Inside, even when the upper tray 171 is removed from the lower tray 172, exposing the top of the lower tray 172, the camera 2P cannot capture the lower tray 172.

[0175] Returning to Figure 11, a card dispensing device 3 is placed on the game table 4. As a card shoe, the card dispensing device 3 has a structure that can store and draw out cards C for the game one by one. The card dispensing device 3 is a so-called electronic shoe that has been used by those skilled in the art, and has the function of judging and displaying the winning and losing results of each game.

[0176] That is, the game rules are pre-programmed in the card dispensing device 3. The card dispensing device 3 reads the information of the card C that has been dispensed and judges the winning and losing results according to the game rules. For example, in a certain card game, B wins, P wins, and T wins, which is basically determined by the face value of 2-3 cards. The judgment result (winning and losing result) is displayed by the result display light 31 of the card dispensing device 3. The card dispensing device 3 with the above functions constitutes the winning and losing result judgment device.

[0177] The game coin tray 17 is embedded in the game table 4 in a state where the upper tray 171 and the lower tray 172 overlap. The game coin tray 17 is embedded in the center of the straight side of the game table 4 with the upper tray 171 protruding from the top of the game table 4, for use by the dealer 5.

[0178] As a device for controlling the management of tabletop games, the management system 100 includes a management control device 15. The management control device 15 includes a game recording device 11, an image analysis device 12, and a cheat detection device 13. A reader 177, a card dispensing device 3, and multiple cameras 2 are connected to the management control device 15. It should be noted that the reader 177 can also be included in the management control device 15.

[0179] The management control device 15 is implemented by executing a management control program using a general-purpose computer equipped with a CPU, memory, storage device, various interfaces, etc. In the example of Figure 11, the game recording device 11, the image analysis device 12, and the cheating detection device 13 are integrated into a management and control device 15, but some or all of them can also be distributed to form a management and control system.

[0180] The game recording device 11 records image data captured and generated by multiple cameras 2. The image data includes tray image data obtained by cameras 2C and 2P capturing game coins 120 contained in the upper tray 171 of the game coin tray 17, and tabletop image data obtained by cameras 2L and 2R capturing the placement area of ​​the game table 4. The game recording device 11 also records tag information read by the reader 177 and the winning / losing result determined by the card dispensing device 3.

[0181] The image analysis device 12 performs image analysis on the image data recorded in the game recording device 11. Specifically, the image analysis device 12 uses machine learning to perform image recognition, thereby detecting game coins 120 from the image data.Convolutional neural networks can be used in the study, and in particular, deep learning can be used to improve detection accuracy. The detection objects of the image analysis device 12 are various game coins 120, various cards C, various banknotes (paper money), the hands of the dealer 5 or player 6, etc. The image analysis device 12 is equipped with an image recognition engine, which learns to recognize the above objects.

[0182] In addition, the image analysis device 12 uses local feature quantities for matching in image recognition, so that it can effectively perform image recognition even in cases of occlusion, dirt or deformation. Specifically, even if the game coins 120 are randomly placed on the table overlapping each other and part of them are occluded, these game coins 120 can still be recognized. Specification 14 / 25 pages 18 CN 120932337 A

[0183] Figure 13 is an explanatory diagram of image analysis of the image analysis device 12. The image analysis device 12 analyzes the movement of the dealer's hand to determine which player collected the game coin 120 from the player and stored in the horizontal storage section 174 of the upper tray 171. In the example of Figure 13, game coin 120-a was collected from player 6La, game coin 120-b was collected from player 6Lb, and game coin 120-c was collected from player 6Lc.

[0184] As a result of the image analysis, the image analysis device 12 outputs information about which player collected which game coin 120, as well as the type and location of the game coins 120 in the upper tray 171, to the cheat detection device 13 and records it in the game recording device 11.

[0185] The cheating detection device 13 uses the analysis results of the image analysis device 12, the game win / loss results of the card distribution device 3, and the tag information of the RF tag 125 read (read out) and recorded in the game recording device 11 by the RFID reading device 170 (antenna 176 and reader 177) to detect cheating. It should be noted that the cheating detection device 13 can perform cheating detection immediately after obtaining the analysis results, the game win / loss results, and the tag information, or it can temporarily record this information in the game recording device 11 and perform cheating detection at a later specified time or at a time specified by the user. The cheating detection will be described in detail below.

[0186] On the game table 4, a settlement is performed after each game. That is, after the game ends, the dealer 5 collects the game coins 120 placed by the losing player 6L according to the game win / loss results, and pays the winning player 6W the game coins 120 corresponding to the amount placed. Multiple cameras 2 acquire the movement of game coins during the settlement process, i.e., the desktop image data and tray image data before and after settlement.

[0187] The image analysis device 12 performs image recognition on the desktop image data in each game, thereby understanding the movement of each player.Player 6 places the game coins 120 in the placement area 8 at any position (for each player, any of P, B, or PAIR), the type of game coins 120 placed (each color of game coin 120 is assigned a different value), and the number of coins. Furthermore, the image analysis device 12 performs image recognition on the tray image data to determine the position, type, and number of game coins 120 stored in the upper tray 171.

[0188] Figure 14 is a perspective view of multiple game coins stacked on the game table 4. As tabletop image data, the game coins 120 are stacked as shown in Figure 14, with clearly defined stripes of the stacking direction on the sides. Therefore, the image analysis device 12 can easily determine the type and number of game coins 120. Moreover, if an AI-efficient computer or control system or deep learning (structure) technology is used, accurate image analysis and judgment can be performed. AI-efficient computer or control system and deep learning (structure) technology are known and usable by those skilled in the art, and will not be described in detail here.

[0189] Figure 15 is a three-dimensional explanatory photograph illustrating the state of stacked game coins 120 of different types. Cameras 2L and 2R capture images of the game coins 120 placed by player 6 on game table 4. The image analysis device 12 determines the category of the area (B, P, PAIR, T) where the coins are placed, and also determines the number and color of the specific color layers 121 of the game coins 120 stacked in each area. The image analysis device 12 makes the above determination when the first card is drawn from the card dispensing device 3, or before or after the card is drawn, or after the dealer 5 gives the signal that the placement is finished.

[0190] The cheating detection device 13 calculates which player 6 will receive a certain amount of settlement (recovery, expenditure) based on the game results (P, B, T) obtained from the card dispensing device 3, the placement objects (P, B, PAIR) of each player 6 obtained by analyzing the table image data, and the amount of their placement. Therefore, the cheating detection device 13 determines the location (P, B, or PAIR) of the game coins 120 in the placement area 8 based on the image analysis results of the image analysis device 12; the type of game coins 120 placed (each different color of game coin 120 is assigned a different value) and the number of coins; and in each game, based on the game's winning or losing result determined by the card distribution device 3, it determines whether to correctly collect the game coins lost by each player 6 (see arrow L) and pay the winning player 6W the game coins (120W) to the winning player 6W.

[0191] When the calculated settlement amount is different from the actual settlement amount determined by the image analysis, the cheating detection device 13 saves the image data in the game recording device 11. The saved image data can be verified later. When the verification result is that the cheating device 13 has a different value than the actual settlement amount determined by the image analysis, the cheating detection device 13 saves the image data in the game recording device 11. The saved image data can be verified later.When the intelligent cheat detection device 13 malfunctions, the analyzed image can be used as sample data for teacher learning in deep learning technology to improve the accuracy of the intelligent cheat detection device 13.

[0192] Based on the analysis results of the tray image data in the image analysis device 12, the cheat detection device 13 calculates the increase or decrease of game coins 120 in the game coin tray 17 before and after settlement, and based on the analysis results of the table image data in the image analysis device 12, calculates the increase or decrease of game coins 120 near each placement area of ​​the game table 4 before and after settlement. In the game coin tray 17, especially as described above, the horizontal receiving portion 174 of the upper tray 171 contains game coins 120 recovered from the game table 4, and the vertical receiving portion 173 of the upper tray 171 pays game coins 120 to each player.

[0193] Before and after settlement, the cheating detection device 13 compares the calculated settlement amount with the increase or decrease in the game coin tray 17, and compares the calculated settlement amount for each player with the increase or decrease in the placement area of ​​each player on the game table 4 to determine whether they are consistent. That is, the cheating detection device 13 determines whether the calculated amount of game coins 120 has been paid to the player 6W who should have paid game coins 120 (the winner of the game), and whether the calculated amount of game coins 120 has been recovered from the player 6L who should have recovered game coins 120 (the loser of the game). When the calculated settlement amount (expenditure amount, recovery amount) is consistent with the increase or decrease in game coins 120 obtained through the analysis of the image analysis device 12, the cheating detection device 13 determines that the settlement is proceeding normally (no cheating).

[0194] When the calculated settlement amount (expenditure amount, recovery amount) is inconsistent with the increase or decrease in game coins 120 obtained through the analysis of the image analysis device 12, the cheating detection device 13 determines that cheating settlement has occurred.

[0195] The image analysis device 12 can determine the types of all game coins 120 contained in the upper tray 171 of the game coin tray 17 of the game table 4 by analyzing the tray image data. The cheating detection device 13 calculates the total amount of all game coins 120 contained in the upper tray 171 based on the analysis results. In addition, the cheating detection device 13 calculates how much the total amount of game coins 120 in the upper tray 171 should increase or decrease after the game ends and is settled, based on the amount of game coins 120L placed by the losing player 6L and the amount of game coins 120W paid to the winning player 6W.

[0196] The total amount of game coins 120 in the upper tray 17 changes with each game and is always monitored through the tray image data, but whether the increase or decrease is correct is determined by the cheating detection device 13 based on the analysis results of the table image data of the image analysis device 12, the game winning or losing results of the card distribution device 3, and the analysis results of the tray image data of the image analysis device 12. This function of the cheating detection device 13 can also be effectively utilized using artificial intelligence or deep learning structures.

[0197] The cheating detection device 13 detects cheating or errors based on the game's winning or losing results, information on which type of game coin 120 is placed in which position (P, B, or PAIR) in the placement area 8 and how many coins are placed, and the increase or decrease in the amount of game coins 120 in the upper tray 171 after recovering game coins 120 from the losing player and paying game coins 120 to the winning player. Therefore, it can detect the movement of game coins 120 after the game ends, that is, even if it is not possible to know whether the placed game coins 120 have moved to the player's side or to the dealer's side, cheating or errors can still be detected.

[0198] Here, as the game's winning or losing results, for example, in the case of a certain card game, the card dispensing device 3 can read the face value of the card C drawn in the game, thereby making a judgment according to the rules of the card game. Furthermore, the outcome of the game can also be determined by using camera 2 to capture images of the game table 4, analyzing the images using image analysis device 12, and comparing the analysis results with the game rules using cheat detection device 13. In this case, camera 2, image analysis device 12, and cheat detection device 13 constitute the outcome determination device. By using camera 2 to capture images of the game coins 120 placed in the placement area 8, and using image analysis device 12 to analyze the table image data of each player's position 7 (see page 16 / 25 of the instruction manual, 20 CN 120932337 A), information can be obtained about the player in each player's position 7, which type of game coin 120 is placed in which position (P, B, PAIR) in the placement area 8, and how many coins are placed there.

[0199] Furthermore, the increase or decrease in the amount of game coins 120 in the upper tray 171 before and after settlement (i.e., collection and payment) can be calculated by comparing the total amount of game coins 120 in the upper tray 171 before such settlement (i.e., collection and payment) with the total amount of game coins 120 in the upper tray 171 after settlement. The total amount of game coins 120 in the upper tray 171 before settlement and the total amount of game coins 120 in the upper tray 171 after settlement can be detected by taking pictures of the upper tray 171 containing game coins 120 using the camera 2 and analyzing the tray image data using the image analysis device 12.

[0200] For example, the total amount of game coins 120 in the upper tray 171 before the start of the game is set as Bb, and the total amount of game coins 120 in the game coin tray 17 after the game ends and settlement is set as Ba. Furthermore, in this game, the total value of 120 game coins placed in area P (8) across all players' positions (7) is bp, the total value of 120 game coins placed in area B (7) across all players' positions (7) is bb, and the total value of 120 game coins placed in area T (7) across all players' positions (7) is bt. For example, when the game results in a win for player B, Ba - Bb.=bp-bb+bt should be true. Or, after the game ends, the total amount Ba of game coins 120 in the game coin tray 17 should be (Bb+bp-bb+bt). If not, it can be determined that there is cheating or error in the settlement of game coins 120 after the game ends.

[0201] The image analysis device 12 knows the position, type and number of game coins 120L placed by the losing player 6L, and the cheat detection device 13 calculates the increase of game coins 120L in the game (the amount of game coins 120 that should be in the game coin tray 171 after recycling). In addition, the image analysis device 12 knows the actual total amount of game coins 120 in the game coin tray 171 after recycling, and the cheat detection device 13 compares the total amount that should be and the actual total amount, and determines whether there is a calculation error.

[0202] Furthermore, by paying the winning player 6W with game coins 120W using the game coins 120 in the longitudinal receiving section 173 located on the upper tray 171, sufficient time is provided for the image analysis device 12 and the cheating detection device 13 to grasp the actual total amount of game coins 120 in the recovered transverse receiving section 174.

[0203] When the cheating detection device 13 determines that cheating has occurred, it records that moment in the game recording device 11. At this time, the cheating detection device 13 can associate the image data used as the basis for determining that cheating has occurred and record that cheating exists. Thus, when verifying the image later, the image at the time of cheating can be replayed.

[0204] When the cheating detection device 13 determines that cheating has occurred, it can immediately output an alarm so that at least the dealer 5 can notice. Thus, the dealer 5 can take measures such as terminating the subsequent game to prevent further cheating. In addition, in this case, image data, tag information, image analysis results, etc., may not be recorded in the game recording device 11.

[0205] It should be noted that, as described above, when the calculated settlement amount is inconsistent with the actual increase or decrease of game coins 120, the cheating detection device 13 determines that cheating has occurred. Therefore, even if it is not intentional cheating, but the inconsistency is caused by negligence, the cheating detection device 13 will still detect it as "cheating". That is, "cheating" in this embodiment also includes situations caused by unintentional negligence.

[0206] During the game, when the upper tray 171 is insufficient to hold game coins 120, a predetermined number (e.g., 100) of game coins 120 are moved from the upper tray 171 to the upper tray 172. Conversely, when the upper tray 171 is insufficient to hold game coins 120, a predetermined number (e.g., 100) of game coins 120 are moved (supplemented) from the lower tray 172 to the upper tray 171. When the cheat detection device 13 moves the game coin 120 between the upper tray 171 and the lower tray 172 as described above, it determines whether cheating, such as removing the game coin 120, is occurring.

[0207] The cheat detection device 13 determines whether the game coins 120 are correctly moved between the upper tray 171 and the lower tray 172 based on the information on the type and number of game coins 120 contained in the upper tray 171 obtained by the image analysis device 12 analyzing the tray image data of the upper tray 171, and the information on the type and number of game coins 120 in the tag information read by the RFID reader 170. That is, if the increase or decrease in the amount of game coins 120 in the upper tray 171 before and after the movement corresponds to the increase or decrease in the amount of game coins 120 in the lower tray 172, the cheat detection device 13 determines that the movement is normal (no cheating); if they do not correspond, it determines that cheating exists.

[0208] When the cheat detection device 13 determines that cheating has occurred, it records the time in the game recording device 11. At this time, the cheating detection device 13 can associate the image data used as the basis for judging cheating movement with the reading data of the RF tag 125 and record that cheating exists. Therefore, when verifying the image later, the image when cheating exists can be replayed.

[0209] When the cheating detection device 13 judges that cheating movement has occurred, it may not record it to the game recording device 11, but instead immediately output an alarm. Therefore, the amusement park manager can take measures such as terminating subsequent games to prevent further cheating. It should be noted that, as described above, when the amount of game coins 120 added or removed in the upper tray 171 is inconsistent with the amount of game coins 120 added or removed in the lower tray 172, the cheating detection device 13 judges that cheating exists. Therefore, even if it is not intentional cheating, but the inconsistency is caused by mistake, the cheating detection device 13 will detect it as "cheating". That is, "cheating" in this embodiment includes situations caused by unintentional negligence.

[0210] The cheating detection device 13 continuously monitors the reading results of the RFID reader 170 within a certain period (e.g., a 1-second period). When the reading results change, it determines whether the change corresponds to the increase or decrease in the amount of game coins 120 in the upper tray 171. Therefore, assuming that the game coins 120 are not moved between the upper tray 171 and the lower tray 172 when the upper tray 171 is removed (in this case, no increase or decrease in the upper tray 171 corresponding to the change in the lower tray 172), cheating can also be detected.

[0211] As described above, in the tabletop game management system 100 of this embodiment, a game coin tray 17 with a double-layer tray structure consisting of an upper tray 171 and a lower tray 172 is used. For the upper tray 171, by processing the image data...Analysis is performed to identify the game coins 120 contained therein. For the lower tray 172, the game coins 120 contained therein are identified by reading tag information from the RF tag 125.

[0212] At this time, the RFID reading device 170 used to read the RF tag 125 of the game coins 120 contained in the lower tray 172 is configured not to read the RF tag 125 of the game coins 120 contained in the upper tray 171. Therefore, there is no situation where it is unknown whether the tag information read by the RFID reading device 170 comes from the game coins 120 contained in the upper tray 171 or from the game coins 120 contained in the lower tray 172.

[0213] In this way, by combining image data and RF tag information, not only can all the game coins 120 contained in the upper and lower game coin trays 17 be identified, but also their movement between the upper tray 171 and the lower tray 172 can be identified, thereby enabling the detection of cheating. Furthermore, for the upper tray 171 used in each game to exchange game coins 120 with players (placement area 8 of game table 4), image data can be used to determine which position of the upper tray 171 contains which type of game coin 120.

[0214] In addition, the cheating detection device 13 calculates the income and expenditure of game coins 120 for each game based on the amount of game coins 120 placed on game table 4 and the winning or losing result of the game, and verifies the increase in the balance of game coins 120 in the game coin tray 17 after the game. When a calculation error is detected in this verification, the cheating detection device 13 issues an alarm or adds the content to the video recording captured by the camera 2. The casino manager can investigate the cause of the calculation error by reviewing the video.

[0215] The cheating detection device 13 of this embodiment adds to or subtracts from the total amount of game coins 120 in the game coin tray 17 before each game settlement, the amount of increase or decrease in game coins in the game calculated based on the position, type and number of game coins 120 placed by all players 6 in the game and the win or loss result of the game obtained by the win or loss result judgment device, and compares the total amount of game coins 120 that should have been in the game coin tray 17 after the game ends and is settled with the actual total amount of game coins 120 in the game coin tray 17 at the end of the game obtained by the image analysis device 12, thereby determining whether there is a calculation error between the total amount that should have been and the actual total amount.

[0216] The cheating detection device 13 uses the image analysis device 12 to determine the location, type, and number of game coins 120 placed by each player. After all the game coins 120 placed by the losing player are collected, the device determines the actual total amount of game coins 120 in the upper tray 171, and compares the total amount of game coins 120 that should exist in the upper tray 171 with the total amount of game coins 120 in the upper tray 171.The actual total amount of game coins 120 is compared to determine whether there is a calculation error between the expected total amount and the actual total amount. The expected total amount is obtained by adding the amount of game coins 120 in the upper tray 171 before each game settlement to the amount of game coins 120 in the upper tray 171, which is calculated based on the position, type and number of game coins 120 placed by the losing player.

[0217] As described above, the upper tray 171 is provided with a horizontal receiving part 174, which is used to collect and temporarily store the game coins 120 placed by the losing player. The cheating detection device 13 compares the expected total amount of game coins 120 in the horizontal receiving part 174 with the actual total amount of game coins 120 in the horizontal receiving part 174 to determine whether there is a calculation error between the expected total amount and the actual total amount. The expected total amount is obtained by adding the amount of game coins 120 in the game, which is calculated based on the position, type and number of game coins 120L placed by the losing player.

[0218] When the cheating detection device 13 determines that there is a calculation error, that is, when the actual total amount of game coins 120 in the upper tray 171 held by the dealer 5 of the game table 4 does not correspond to the increase or decrease of game coins 120 calculated from the total amount of game coins 120 placed by all players and the result of winning or losing the game, the game recording device 11 can add an index or time to the acquired image, or determine and replay the game coin 120 recycling scenario or payment scenario, so that the game record that caused the above-mentioned calculation error can be analyzed in the game recording device 11.

[0219] Accordingly, the cheating detection device 13 obtains the total amount of game coins 120 in the upper tray 171 after the game ends and the settlement is completed by the image analysis device 12. The determination after settlement in this case is performed at any of the following 1) to 4):

[0220] 1) When the payment to the winning player ends;

[0221] 2) When the card C used in the game is recycled and discarded in the discard area or discard slot of the game table 4 (not shown);

[0222] 3) When the prescribed button attached to the win / loss result determination device (card distribution device 3) is pressed (the start button for the next game, the confirmation button for the win / loss result, etc.);

[0223] 4) When the sign indicating win / loss is restored to its original state.

[0224] Furthermore, the cheating detection device 13 is an artificial intelligence-effective or deep learning structure capable of knowing the position (P, B, or PAIR) and amount (type and number) of game coins 120 placed at each player's position 7 at the game table 4, and comparing the win / loss history of each player 6 obtained through the win / loss results of each game with the amount of game coins 120 obtained (the amount won) with statistical data (big data) of a large number of past games to extract abnormal situations suspected of cheating (set by the casino).

[0225] It is a cheating detection device 13 with an effective artificial intelligence or deep learning structure. That is, as a typical example, it compares the situation of winning a certain amount (1 million points) or more, or the situation of placing a small amount of game coins 120 when losing and a large amount of game coins 120 when winning in a certain game table 4 for several consecutive games with the statistical data (big data, etc.) of past games, and can extract it as an anomaly.

[0226] Furthermore, the management control device 15 of the management system 100, which includes the cheating detection device 13 and the image analysis device 12, determines the individual player 6 at the player position 7 that is extracted as an anomaly and the individual player 6 at the player position 7 who has won a certain amount or more. The player 6 can be determined as above by performing image recognition on the facial image of each player in the image analysis device 12 using feature point extraction and the like. After identifying player 6, the cheating detection device 13 provides an identification number (ID, etc.) and records the information of the identified player 6. Furthermore, the cheating detection device 13 has a warning function; that is, when the identified player 6 leaves their seat to sit at another game table 4, the other game table 4 is notified of the presence of player 6. Specifically, the manager or person in charge of each game table 4 (or the dealer) is notified to prevent further anomalies.

[0227] The cheating detection device 13 also has a database that stores historical records of the purchase of game coins 120 using paper money K. It can refer to the database at certain intervals or on a daily basis to compare and determine whether the amount of game coins 120 in the game coin tray 17 held by the dealer 5 of the game table 4 corresponds to the payment amount of game coins 120 used to purchase paper money K or the total amount of paper money K corresponding to the purchased game coins 120, and deduct accordingly.

[0228] It should be noted that in the above example, it is not necessary to be certain about individual players 6, but rather to monitor the win / loss history of each player's position 7 and the amount of game coins 120 obtained (winning amount). In this case, when each player 6 leaves their seat, it is not possible to track that player 6, but it is possible to detect abnormal situations such as a small amount of game coins 120 placed when losing and a large amount of game coins 120 placed when winning persisting for several games at a specific player position 7 of a game table 4. Furthermore, when such a player position 7 is detected, it is suspected that there may be cheating or errors at that player position 7. Furthermore, cheating or errors can be discovered by verifying the video taken at that player position 7.

[0229] Specifically, the camera 2 is set to at least capture the game coins 120 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, for each player position 7, detects the game coins placed in the placement area 8.The card dispensing device 3 can also be used as a win / loss result determination device to determine the win / loss result of the game.

[0230] The cheating detection device 13 records (monitors) the win / loss history and the amount of game coins obtained (game coin acquisition amount) of each player's position 7 on the game recording device 11 based on the position (P, B or PAIR) of the game coin 120 in the placement area 8 and the win / loss result of the game. It should be noted that either the win / loss history or the game coin acquisition amount can be recorded. When the win / loss history and / or the game coin acquisition amount is determined to be an abnormal situation (set by the casino) after being compared with the statistical data (big data) of a large number of past games, the cheating detection device 13 determines that the player's position 7 is a player position suspected of cheating.

[0231] When cheating is suspected in player position 7, the management control system 100 can issue an alarm (light, sound, or vibration) to at least make the dealer 5 aware of it. This allows for immediate intervention, such as terminating the game, to prevent further cheating. Furthermore, information indicating suspected cheating can be added to the footage captured and recorded by the camera 2. This allows for investigation into the cause of suspected cheating through video.

[0232] In this embodiment, the management control system 100 in the amusement park with the game table 4 also has the function of checking the frequent exchange of banknotes and game coins at the game table 4. In amusement parks such as casinos, before the game, player 6 purchases game coins with banknotes at a designated game coin purchase location. However, when player 6 runs out of game coins, they can continue playing at the game table (such as a card game table) by purchasing game coins 120 with banknotes without leaving the game table 4. However, this creates an opportunity for cheating between the dealer 5 and player 6.

[0233] At a game table (such as a card game table), game coins 120 need to be purchased with banknotes when not playing a game. The card dispensing device 3 can detect the start and end of card dealing (the period that determines the winner) in order to determine the outcome of the game. Therefore, the card dispensing device 3 detects situations other than card distribution (dealing), and the cheating detection device 13 detects the purchase of game coins 120 with banknotes at the game table 4 in situations other than card dealing. Information obtained from the operation of the card dispensing device 3 or the dealer 5, as described on pages 20 / 25 of the instruction manual (CN 120932337 A), can detect if card dealing is in progress (or other situations).

[0234] The image analysis device 12 can analyze the surface image of the banknote K to identify the number and amount of banknotes. Furthermore, in the game...On the game table 4, the authenticity mark of the banknote is detected by illuminating it with invisible light to determine whether the banknote K used to purchase game tokens 120 is real money. The image analysis device 12 is constructed as an AI-efficient or deep learning structure: it also performs image analysis and verification on the authenticity mark to identify the total amount of real money, and even if multiple game tokens appearing on the game table as purchase objects are hidden due to the blind spot of the camera 2, it can still identify the total amount of game tokens, and can compare the total amount of banknote K taken out by the player on the game table 4 with the total amount of game tokens 120 taken out by the dealer 5 to determine whether the two amounts are consistent.

[0235] The cheating detection device 13 is an AI-efficient or deep learning structure: it can compare and calculate whether the total amount of game tokens 120 in the upper tray 17 of the game table 4 has been reduced after purchasing game tokens 120 with banknotes and settling the payment, corresponding to the payment amount of game tokens 120 used to purchase the banknotes. The total amount of game coins 120 in the upper tray 171 held by the dealer 5 can be detected by the camera 2 taking a picture of the upper tray 171 containing the game coins 120 and analyzing the image using the image analysis device 12.

[0236] In addition, the cheating detection device 13 verifies whether the reduction in the amount of game coins 120 in the game coin tray 17 before and after purchasing game coins with paper money is consistent with the amount of game coins purchased as shown in the image analysis on the game table 4. The amount of paper money paid can be input by the dealer 5 to the management control device 15 through key input, or the camera 2 can take a picture of the game table 4 where paper money is paid and the image analysis device 12 can analyze the image to determine the amount.

[0237] As described above, the cheating detection device 13 determines whether the reduction in the amount of game coins 120 in the game coin tray 17 caused by purchasing game coins with paper money is consistent with the amount of paper money paid by the player 6 to the dealer 5. Furthermore, the cheating detection device 13 is an intelligent control device that, after purchasing game coins with paper money and settling accounts, can compare and calculate the consistency between the amount of paper money entered by the dealer 5 (usually through key input, etc.) and the amount of paper money calculated by the image analysis result of the image analysis device 12. It can also be an artificial intelligence-effective or deep learning structure.

[0238] Furthermore, the cheating detection device 13 is an artificial intelligence-effective or deep learning structure capable of comparing and calculating the consistency between the total amount of paper money entered by the dealer at the game table 4 under the dealer's responsibility and the total amount of paper money obtained according to the image analysis result of the image analysis device 12.

[0239] The cheating detection device 13 calculates whether the amount of game coins 120 held by the dealer 5 in the game coin tray 17 of the game table 4 corresponds to the game coins 120 used for purchasing after purchasing game coins 120 with paper money.The amount paid is reduced by the amount of banknotes used to purchase game tokens 120, and the difference is compared and determined.

[0240] The cheating detection device 13 is a control device with an effective artificial intelligence or deep learning structure: when determining and judging the type and number of game tokens 120, even if part or all of the game tokens are hidden, information on the type and number of game tokens 120 can be obtained.

[0241] FIG16 is a side view showing a modified example of game tokens 120. Game tokens 120 are formed by stacking multiple sheet-like plastic layers of different colors, forming them into one piece by hot pressing or other means, and then stamping them into a circle or quadrilateral. The game tokens 120 thus produced have the following multi-layer structure: at least in the middle, there is a specific color layer 121, and light-colored layers 122 are stacked on both sides (top and bottom in FIG16) of the specific color layer 121 in the middle.

[0242] Accordingly, by fabricating a multi-layer structure having a specific color layer 121 and light-colored layers 122 stacked on both sides of the specific color layer 121 in the middle, as shown in FIG16, when viewed from the side, stripes are formed in the stacking direction, and the color of the specific color layer 121 (red, green, yellow, blue, etc.) is changed according to the type of game coin 120 (10 points, 20 points, 100 points, 1000 points, etc.), thereby determining the type of game coin 120.

[0243] Furthermore, as shown in FIG16, a side code 126 indicating the type of game coin 120 is applied to the side of the light-colored layer 122 on the game coin 120. A transparent layer 124 is provided on the outermost layer, and the layers are heat-pressed together to form a structure of at least five layers. These game tokens 120 are made of a long, thin plastic material. In the long, thin state, the layers (at least the specific color layer 121 and the light color layer 122) are heat-pressed together to form a tightly bonded state (five-layer structure, etc.), and then formed into a circle or rectangle by a press or the like.

[0244] The dimensions of the die and punch used for stamping by the press are set, and R processing (rounded corners) is applied to the end of the outermost layer 124. The transparent layer 124 may also be a varnish coating layer. Side codes 126 are attached to at least three places on the side of the game token 120. The side codes 126 are attached by inkjet printing using ink visible under visible light.

[0245] In particular, in this modified example, the side codes 126 are constructed and attached in a manner with or without multiple rows and columns of markers M. As shown in FIG16, the multiple rows and columns of markers M form a code in pairs of upper and lower markers M. In the example of FIG16, a 10-digit code is formed.

[0246] Figure 17 is a diagram showing the codes (four types) represented by the upper and lower sets of markers M. The "Y" next to marker M is an identification mark used to identify the upper and lower parts of the marker. The code formed by marker M is configured to determine the specified characteristics of marker M.Combinations. As a result, in the example shown in FIG17, there are four combinations of the upper and lower columns of mark M. If they are printed in 10 columns, four to the power of 10 kinds of codes can be formed. There are four 10-digit codes, which can result in 4 to the power of 10 kinds of codes. Therefore, the side ID 126 of the game coin 120 can be sufficiently assigned.

[0247] The game coin 120 is formed as a multi-layer structure, that is, multiple plastic layers of different colors are stacked, and at least one layer has a specific color layer 121. A light color layer 122 is stacked on the outside of the specific color layer 121, thereby forming stripes in the stacking direction on the side. The type of game coin 120 can be determined by the specific color layer 121. The side codes 126 are provided at least three (preferably six) on the side of the light color layer 122 in a circumferentially spaced manner. In the examples of FIG16 and FIG17, the six side codes 126 are provided in the circumferential direction at 60-degree intervals.

[0248] Of course, all six side codes 126 represent the same information. Each game coin 120 is attached with a uniquely identifiable side code 126, and these side codes are spaced at 60-degree intervals in the rotational direction (circumferential direction), ensuring they are always visible from the side. The side code 126 includes identification information (each uniquely identifiable) that identifies each game coin 120, information indicating the type of the game coin 120, and manufacturing information (manufacturing structure, manufacturing date, etc.).

[0249] The side code 126 attached to the game coin 120 is read by the image analysis device 12 described above. The management control device 15 includes a database (not shown in the figure) storing identification information, type, and manufacturing information for all manufactured game coins 120 (at least those likely to be used in the amusement park), and these information are interconnected.

[0250] The image analysis device 12 reads the side code 126 from image data (tabletop image data and tray image data). Based on the reading results of the image analysis device 12, the cheat detection device 13 determines the identification information, type, and manufacturing information of the game coin 120 included in the image data, and compares their combination with the information stored in the database.

[0251] When there is a game coin 120 whose information read by the image analysis device 12 is inconsistent with the information stored in the database, the cheat detection device 13 determines that the game coin 120 is a cheat (counterfeit or damaged) game coin 120. When the cheat detection device 13 detects cheating in this way, it records the position information of the cheat game coin 120 and its time together in the game recording device 11.

[0252] At this time, the cheat detection device 13 can use the image data (desktop illustration, manual pages 22 / 25, 26 CN 120932337 A) as the basis for judging the cheat game coin 120.The location information and time of the cheating game coin 120 are recorded by associating it with data such as data or tray image data. Therefore, the image of the cheating can be replayed when verifying the image later.

[0253] In this modified example, the side code 126 is affixed by inkjet printing using ink visible under visible light. The side code 126 can also be printed using any one or a combination of inks that are not visible under visible light (e.g., inks that absorb ultraviolet light) or inks that are at least visible under visible light (including very small inks that are not easily seen). Furthermore, a combination of the above-mentioned inks can be used to print the side code 126.

[0254] As camera 2, the management system 100 has at least a plurality of cameras corresponding to the ink used to print the side code 126 (i.e., a visible light camera when the ink is visible ink; an infrared camera when the ink is infrared reactive ink; and an ultraviolet camera (UV irradiator and visible light camera) when the ink is UV ink), or cameras 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.).

[0255] FIG18 is a side view showing other examples of side codes. On game coin 120-1, the side code 126 is printed using ink that is not visible under visible light (e.g., ink that absorbs infrared light). On game coin 120-2, the multi-row, multi-column mark M is printed using ink that appears black under visible light. On coin 120-3, in addition to the mark M of coin 120-2, the side codes 126 are also printed with marks M that appear black under visible light, making the side codes 126 blend into the design and thus inconspicuous. On coin 120-4, the starting and ending points of the repeatedly attached side codes 126 are indicated by the mark Cf indicating the end.

[0256] As for coins 120-1 to 120-4, when viewed with an infrared camera, the infrared-absorbing ink absorbs infrared light and thus appears black, so the same side codes 126 appear from any side. That is, an image of coin 120-5 can be obtained by an infrared camera. Furthermore, the top and bottom of the side codes 126 are indicated by the mark CL indicating top and bottom. The top and bottom relationship of the marks is shown in Figure 16. It should be noted that a combination of ink visible under visible light and infrared-absorbing ink can also be used to print the side codes 126.

[0257] The side code 126 attached to the game coin 120 is read by the image analysis device 12. The image analysis device 12 is capable of reading the side code 126 of the game coin 120 housed in the upper tray 171 of the game coin tray 17 and the game coin 120 placed on the game table 4.

[0258] FIG19 is tray image data showing the game coin 120 housed in the upper tray 171 of the game coin tray 17.The image shows that the game coins 120 are stacked horizontally (horizontally) in the tray image data. The image analysis device 12 can also read the side code 126 from these tray image data. In addition, the image analysis device 12 can also read the side code 126 from the game coins 120 on the game table 4 as represented by the table image data.

[0259] FIG20 is a perspective view of multiple game coins stacked on the game table 4. On the game coin 120, a face code FC is provided on the surface X of the light-colored layer 122 using UV ink or ultraviolet-absorbing ink (carbon black ink). The face code FC indicates whether the game coin 120 is genuine or counterfeit. When exposed to ultraviolet (or infrared) light, the face code FC is visible. The combination of its shape and number indicates that it is a genuine coin.

[0260] A transparent layer (printed layer) 124 is hot-pressed or coated on the outermost layer to further cover the amusement park markings 123 (such as 10 dots) and face code FC on the surface. The transparent layer 124 is embossed or varnished to prevent the game coins 120 from sticking together and to make it smoother. The game coin 120 has a circular recess 127 in the center of its upper and lower surfaces. The recess 127 prevents the game coins 120 from sticking together, and the diameter of the recess 127 can be increased to make the game coin 120 smoother.

[0261] The ends of the outermost transparent layer (printed layer) 124 on which the printing 123 (such as 100 dots) is applied are coated with R (R) to prevent the surface of the light-colored layer 122 from deforming and appearing on the side during the stamping process of the game coin 120. Furthermore, to prevent the sharp ends of the game coin 120 from remaining and damaging hands or other game coins 120.

[0262] The specific color layer 121 may also be formed by one or more colored layers. Furthermore, metal or ceramic for adding weight may be embedded in the layers of the specific color layer 121. Specifically, the material of the layers of the specific color layer 121 may contain, for example, metal powder for adding weight (e.g., one or more metal oxides such as zinc oxide and titanium oxide). Furthermore, a portion of the specific color layer 121 may be removed or a space may be provided between the specific color layer 121 and the light color layer 122 to embed an RF tag 125 therein. As tag information, the RF tag 125 stores information that is partially or entirely the same as the information represented by the side code 126.

[0263] The cheat detection device 13 compares the side code 126 read from the image data (desktop image data and tray image data) by the image analysis device 12 with the information stored in the database, thereby detecting the cheating game coin 120. Specifically, the cheat detection device 13 determines that cheating game currency 120 exists under the following circumstances:

[0264] 1) The side code 126, which does not exist in the database, exists; and

[0265] 2) There are two or more identical side codes.

[0266] As described above, player 6 can purchase game coins at the cashier, but game coins 120 can also be purchased at the game table 4. Cameras 2L and 2R photograph the banknotes placed on the game table 4 to purchase game coins 120. That is, multiple cameras 2L and 2R that photograph the game coins 120 on the game table 4 are respectively arranged in different positions.

[0267] Based on the banknote recognition result of the image analysis device 12, the cheating detection device 13 determines the type and number of game coins that should be paid from the upper tray 171 when purchasing game coins 120 with banknotes. The cheating detection device 13 compares the actual total amount of game coins 120 stored in the upper tray 171 before and after expenditure, thereby determining whether the difference corresponds to the determined type and number of game coins 120 to be paid.

[0268] That is, the cheating detection device 13 compares and determines whether the total amount of game coins 120 held in the upper tray 171 corresponds to the deduction made after purchasing game coins 120 with paper money. In addition, when the collection and payment are also carried out simultaneously according to the game's win or loss results, the cheating detection device 13 compares and determines whether the increase or decrease of game coins 120 calculated based on the total amount of game coins 120 placed by all players 6 corresponds to the game's win or loss results.

[0269] Here, the cheating detection device 13 is a control device with an effective artificial intelligence or deep learning structure: When determining the type and number of game coins 120, even if a part or a whole of the game coins 120 is hidden, the information on the type and number of game coins 120 can be obtained.

[0270] As described above, the game coin 120 has a side code 126 affixed at least three times in the rotational direction (circumferential direction) on the light-colored layer 122 on its side at intervals. By reading the side code 126 by the image analysis device 12, the type and manufacturing information of the game coin 120 can be determined. The information determined in this way is compared with a database.

[0271] FIG21 is a side view of a game coin showing another example. In this example, a light-colored layer 122 is provided in the center of the side of the game coin 120, and specific color layers 121 are provided above and below it. On the light-colored layer 122 sandwiched by the specific color layers 121, a 7-digit number is printed as a mark for the side code 126, which constitutes the side code 126. There are 10 to the power of 7 possible combinations of numbers, therefore, 10 to the power of 7 possible side codes 126 can be provided. The image analysis device 12 identifies the 10-digit number by performing image recognition based on machine learning.

[0272] Industrial Applicability

[0273] As described above, the present invention has the following effects: by utilizing a camera to monitor the input or output of data during game settlement...The upper tray of game coins can be photographed to confirm the position and movement of the game coins, thereby detecting cheating. Regarding the storage instructions (pages 24 / 25, CN 120932337 A), the lower tray of game coins can be read even when the upper tray is stacked on top of it, but the RF tag of the game coins on the upper tray will not be read. Therefore, it has the effect of knowing the game coins stored in the lower tray by reading the RF tag, making it very useful as a game coin tray.
