Description

[0001] Divisional application This application is a divisional application of Chinese patent application No. 202210252507.0, filed on March 11, 2022, entitled "Inspection System". Technical Field

[0002] This invention relates to an inspection system for game coins with built-in RFID tags. Background Technology

[0003] Previously, there was a type of game coin with built-in RFID tags. By storing the amount and identification information of the game coin in the RFID tag, it is possible to detect cheating game coins, manage game coin inventory, and perform customer rating. The advantage of RFID technology is that it can read multiple RFID tags simultaneously using an RFID reader, thus processing a large number of game coins at once. For example, by reading the RFID tags of multiple game coins stored in a game coin tray simultaneously using an RFID reader, information such as the number of game coins and their total value can be obtained.

[0004] On the other hand, there is a problem: when using RFID technology to read the RFID tags of multiple game coins, it is impossible to detect cheating game coins or game coins with faulty RFID tags. For example, in a large number of game coins (e.g., 1000), if there is one game coin with a faulty RFID tag or no RFID tag mixed in, the result is that even if the RFID reader reads 999 RFID tags, it is not known that there are 1000 game coins. Even if it knows that 999 RFID tags have been read, it is impossible to know that there is one game coin whose RFID tag was not read.

[0005] Furthermore, even if it is known that cheating tokens or tokens with malfunctioning RFID tags are mixed in among multiple game tokens, determining which specific token among them has such a problem is not easy. For example, even if it is known that there is one problematic token among 1000 game tokens, finding that problematic token requires checking each one individually, which consumes labor and time.

[0006] Furthermore, the following cheating methods may also exist: altering the appearance of game tokens to resemble those of higher-value tokens without altering the RFID tags; removing the RFID tag from one game token and replacing it with the RFID tag of another; or using RFID tags taken from genuine game tokens to create counterfeit game tokens. In such cheating, since the information stored in the RFID tags is correct, simply reading the RFID tag cannot identify the game token as problematic (appearance altered). Summary of the Invention

[0007] In view of the above-mentioned problems, the present invention provides a system for checking whether game coins are problematic.

[0008] One aspect of the present invention is an inspection system for inspecting game coins, wherein the game coin has a built-in RFID tag storing type information and / or identification information, and the type information and / or identification information is displayed on its surface. The inspection system comprises: The mounting surface has multiple areas for placing and inspecting multiple related game coins one by one; An RFID reading system reads the RFID tags of game coins placed in each of multiple areas of the mounting surface, and obtains the type information and / or identification information for each area. A game coin recognition system that identifies the presence or absence of game coins in each of multiple areas placed on the mounting surface; A control device, for each area of ​​the mounting surface, determines the status of the game coins in that area based on the type information and / or identification information acquired by the RFID reading system and the identification result of the game coin identification system; and The display device displays a state determined by the control device for each of the said areas. The states determined by the control device include at least the following states: (1) The game currency in this area is normal; (2) The RFID tags on the game tokens in this area are damaged or not embedded; and (3) There are no game coins in this area; The control device is configured such that, for the game coin identification system that identifies game coins but the RFID reading system cannot read the RFID tag in the area, it is determined that (2) the RFID tag of the game coin in that area is damaged or does not have a built-in RFID tag; for the area where the identification system cannot identify game coins, it is determined that (3) there are no game coins in that area.

[0009] The aforementioned inspection system may also include a storage device that stores at least the identification information of multiple game coins. For game coins whose identification information read by the RFID reading system is not stored in the storage device, the control device may determine that they are in an abnormal (counterfeit) state.

[0010] In the above inspection system, multiple configuration areas formed by the multiple areas arranged side by side in the row direction can be arranged side by side in the column direction. The control device can determine that a game coin whose identification information read by the RFID reading system is different from the type information of the game coins adjacent to each other on both sides in the row direction is in an abnormal state.

[0011] In the above inspection system, multiple configuration areas formed by the multiple areas arranged side by side in the column direction can be arranged side by side in the row direction. The control device can determine that a game coin whose identification information read by the RFID reading system is different from the type information of the game coins adjacent to each other on both sides in the column direction is in an abnormal state.

[0012] In the above inspection system, multiple configuration areas formed by the multiple areas arranged side by side in the row direction can be arranged side by side in the column direction. The control device can determine that a game coin whose identification information read by the RFID reading system has no specified relationship with the type information of other game coins adjacent to each other in the column direction is in an abnormal state.

[0013] In the above inspection system, multiple configuration areas formed by the multiple areas arranged side by side in the column direction can be arranged side by side in the row direction. The control device can determine that game coins whose identification information read by the RFID reading system has no specified relationship with the type information of other game coins adjacent in the row direction are in an abnormal state.

[0014] In the aforementioned inspection system, the types of game coins that should be placed can be defined in the multiple configuration areas. For each of the multiple configuration areas, if the type information read by the RFID reading system does not correspond to the type defined in that configuration area, the control device can determine that the game coin is in an abnormal state.

[0015] In the aforementioned inspection system, the control device can determine that the RFID tag reading is unstable if the game coins are in an area where the RFID tag reading is unstable.

[0016] In the above inspection system, the RFID reading system can change the intensity of the radio wave or magnetic field used to read the RFID tag for each area. The control device can determine that the reading of the game coin in the area where the intensity of the radio wave or magnetic field can be read when the intensity of the radio wave or magnetic field is increased but cannot be read when the intensity of the radio wave or magnetic field is decreased is that the reading of the RFID tag is unstable.

[0017] In the aforementioned inspection system, the game coin identification system can use optical methods to identify at least one type of game coin in each of multiple areas placed on the mounting surface. The control device can determine that a game coin whose type information read by the RFID reading system does not correspond to the type determined by the game coin identification system is in an abnormal state. In the above inspection system, the game coin identification system can be an image recognition system equipped with a camera and an identification device. The camera takes a picture of the game coin placed on the placement surface and generates a picture image. The identification device analyzes the picture image to identify the type of game coin for each area.

[0018] The aforementioned inspection system may also include a storage device that stores at least a plurality of the type information of the game coins in association with the identification information. The control device may determine that a game coin whose type identified by the game coin identification system does not correspond to the type information in the storage device associated with the identification information read by the RFID reading system is in an abnormal state.

[0019] In the aforementioned inspection system, the control device can determine that a game coin whose type identified by the game coin identification system does not correspond to the type information read by the RFID reading system is in an abnormal state.

[0020] The aforementioned inspection system may also include a database that stores at least a plurality of the game coins' identification information in association with the game coin's validity information. The control device may determine that a game coin is invalid if the validity information associated with the identification information read by the RFID reading system in the database is not valid.

[0021] In the aforementioned inspection system, the game coin can store the identification information in the RFID tag, and also has the identification information in a manner other than the RFID tag. The storage device can also store the reading history of the RFID reading system. When it is determined that the RFID tag of the game coin is damaged or does not have a built-in RFID tag, the control device can use the identification information in a manner other than the RFID tag to obtain the reading history of the game coin stored in the storage device.

[0022] In the above inspection system, the display device may be a plurality of lights that represent the status by color and are arranged corresponding to each of the plurality of areas.

[0023] In the above inspection system, the lamps can be installed in various regions of the mounting surface.

[0024] In the above-mentioned inspection system, the display device can be a display panel composed of multiple pixels arranged in a two-dimensional array.

[0025] In the above inspection system, the display panel can at least display an area representing the forged content and / or the faulty content.

[0026] In the aforementioned inspection system, the display panel can at least display the normal number of game coins.

[0027] In the above inspection system, the display panel can display the type information read by the RFID reading system for each area.

[0028] The aforementioned inspection system may further include: multiple configuration surfaces for placing multiple game coins, and a second RFID reading system for reading the RFID tags of the multiple game coins placed on the multiple configuration surfaces and obtaining the type information and / or identification information.

[0029] Another aspect of the present invention provides an inspection system for inspecting game coins, the game coins having built-in RFID tags storing type information and displaying the type information on their surface. The inspection system comprises: a configuration area having multiple zones for placing multiple game coins related to the inspection one by one; an RFID reading system that reads the RFID tags of game coins placed in each of the multiple zones and acquires the type information for each zone; a control device that determines a cheating game coin for each zone of the mounting surface; and a display device that displays the determination result of the control device for each zone, wherein the control device determines the presence of the cheating game coin when it acquires the type information for multiple types from the multiple zones.

[0030] In the above inspection system, the multiple configuration areas formed by the multiple regions arranged side by side in the column direction can be arranged side by side in the row direction, or the multiple configuration areas formed by the multiple regions arranged side by side in the row direction can be arranged side by side in the column direction. For each of the multiple configuration areas, the control device can determine whether multiple types of category information have been obtained from the multiple regions.

[0031] In the aforementioned inspection system, when multiple types of type information are obtained from the multiple areas, the control device can determine the game coins in the area where type information is obtained that is different from the majority of the type information as the cheating game coins.

[0032] Another aspect of the present invention provides an inspection system for inspecting game coins, wherein the game coins have an RFID tag embedded with at least type information. The inspection system comprises: a mounting surface having multiple areas for placing multiple game coins related to the inspection one by one; an RFID reading system for reading the RFID tags of the game coins placed in each of the multiple areas of the mounting surface; and a display device for displaying the type information read by the RFID reading system for each of the multiple areas.

Detailed Implementation

[0034] Hereinafter, several embodiments of the present invention will be described, but the present invention is not limited to the following embodiments, and the technical elements and functions of the various embodiments can be arbitrarily combined. Furthermore, the following description will use a round game coin as an example of a game coin.

[0035] (First Implementation) This embodiment of the inspection system is for inspecting game coins received by players at counters or game tables during exchange of coins or coins, or game coins recovered from players who have lost games. This embodiment of the inspection system can also inspect game coins held in coin trays at casino counters or game tables at any time. This embodiment of the inspection system includes a stand for placing game coins one by one, and the stand is equipped with a game coin reader. Furthermore, game coins can be placed on the stand in groups of five according to type.

[0036] Figure 1 This diagram illustrates the structure of the inspection system according to the first embodiment of the present invention. The inspection system 101 is a system for inspecting game coins and includes: a platform 10 having a mounting surface 120; a display device 20 for displaying inspection results; a control device 30 for performing calculations for inspection; and a storage device 40 storing information about the game coins.

[0037] The upper surface of the mounting platform 10 forms a mounting surface 120, which is divided into multiple coin configuration areas for placing and inspecting multiple related game coins one by one. Figure 1 In the example, the mounting surface 120 has 25 coin configuration areas arranged in 5 rows and 5 columns. Each coin configuration area receives one coin. These coin configuration areas can be divided by printed lines on the mounting surface 120, and adjacent coin configuration areas can also be separated by walls of about a few centimeters in height. Alternatively, each coin configuration area can also have a groove for receiving coins.

[0038] Figure 2 This diagram illustrates the structure of the game coin and its database. The obverse and reverse sides of the game coin 110 display numbers indicating its type (amount). The obverse and reverse sides also display identification information inherent to the game coin 110 (e.g., identification number). This identification information can be printed with inks that are not visible under natural light, such as ultraviolet-reactive inks or infrared-absorbing inks. In this case, the identification information can be visualized by irradiating the game coin with ultraviolet or infrared light.

[0039] The game coin 110 has a built-in RFID tag 111. The RFID tag 111 stores information about the type (amount) and identification information of the game coin. The RFID tag 111 can also store other information such as information about the casino where it was used, manufacturing information, and owner's historical information.

[0040] The storage device 40 stores information such as type (amount), identification information, activation status, and reading history for each game coin. When a game coin is brought into the casino and can be used there, the storage device 40 sets the activation status to valid. When a game coin cannot be used in the casino due to malfunction, deterioration, suspected cheating, theft, etc., the storage device 40 sets the activation status to invalid (inactive). The reading history stores the locations of RFID readers that read the game coin in chronological order. In other words, the reading history is the movement history of the game coin within the casino, linking players or dealers with the game coin.

[0041] Storage device 40 is updated periodically. When storage device 40 or the inspection system 101 including storage device 40 is connected to a communication network, update data can be sent to each storage device 40 via the communication network.

[0042] Return to Figure 1 In the mounting platform 10, each of the multiple coin placement areas on the mounting surface 120 is equipped with an object detection sensor 11 for detecting the presence or absence of coins placed in the coin placement area. Each object detection sensor 11 consists of a combination of a laser illuminator and a laser receiver. When an object (coin) is present in the coin placement area, an ON signal is output.

[0043] Furthermore, each of the multiple coin configuration areas on the mounting surface 120 of the mounting platform 10 is equipped with an RFID reading system. This RFID reading system reads the RFID tags 111 of the coins 110 placed in each coin configuration area and obtains type and identification information for each coin configuration area. The RFID reading system includes: an antenna for reading information from the RFID tags, and an RFID reader for controlling the antenna.

[0044] Figure 3 This diagram illustrates an example of the antenna and the intensity distribution of its radio or magnetic fields on the mounting platform of this embodiment. In this example, a reading antenna 121 and an interference antenna 122 are provided for each coin configuration area. The reading antenna 121 generates radio or magnetic waves, supplies power to the RFID tag 111, and reads information from the RFID tag 111.

[0045] The interference antenna 122 generates radio waves or magnetic fields induced by the radio waves or magnetic fields emitted by the reading antenna 121 of the surrounding game coin configuration area, and shapes the radio waves or magnetic fields of the reading antenna 121 of the surrounding game coin configuration area. Figure 3 As shown in the lower half, due to the function of the interference antenna 122, the radio waves or magnetic fields formed by the reading antennas 121 of each game coin configuration area have a specified strength only within the game coin configuration area and become weak outside the game coin configuration area. Therefore, the reading antenna 121 can be prevented from reading the RFID tag 111 of the game coin 110 outside the game coin configuration area.

[0046] By combining the reading antenna 121 with the interference antenna 122, the game coins 110 placed in each game coin configuration area will not be read by the reading antenna 121 configured in other game coin configuration areas. This allows for the separate reading of RFID tags 111 for each game coin configuration area as a whole.

[0047] The positive and negative terminals of the reading antenna 121 are connected to the RFID reader, and current flows out of the RFID reader. The interfering antenna 122 has a switch 123. If the switch 123 is closed, a closed loop is formed; if the switch 123 is open, the closed loop is open. The RFID reader controls the opening and closing of the switches of each interfering antenna 122.

[0048] The RFID reader sequentially reads RFID tags from multiple coin-equipped areas by activating the reading antennas 121 of each area one by one, in a time-divided manner. When switching between coin-equipped areas, the RFID reader simultaneously closes the interfering antennas 122 of surrounding coin-equipped areas, thus preventing interference. This prevents the reading antennas 121 of the currently being read area from reading RFID tags in surrounding coin-equipped areas.

[0049] Figure 4 This diagram illustrates another example of the antenna provided on the mounting platform of this embodiment. In this example, elongated reading antennas 124 and 125 are provided in each row and column of the game coin arrangement area, which is arranged in a two-dimensional matrix. It should be noted that although the diagram is omitted, the antennas are similar to... Figure 3 Similarly, interference antennas may be provided corresponding to each read antenna 124 and read antenna 125.

[0050] In this example, with such Figure 3Compared to the example where a reading antenna 121 is configured for each game coin configuration area, the number of reading antennas 124 and 125 can be reduced. The RFID reader uses multiple reading antennas 124 and 125 sequentially to read RFID tags in rows or columns.

[0051] For example, the RFID tag 111 of the game coins 110 in the first row of the coin configuration area of ​​the mounting platform 10 can be read via the reading antenna 124 in the first row. Furthermore, the RFID tag 111 of the game coins 110 in the first column of the coin configuration area of ​​the mounting platform 10 can be read via the reading antenna 125 in the first column. The RFID tags read in both the first row and the first column are the RFID tags 111 of the game coins 110 configured in the first row and first column of the coin configuration area, which is arranged in a two-dimensional matrix.

[0052] In this way, the RFID reader reads multiple rows one by one and multiple columns one by one, and by referring to these reading data, it is able to identify the RFID tag 111 of the game coin 110 placed in each game coin configuration area.

[0053] Return to Figure 1 For each coin configuration area, the control device 30 determines the status of the coin 110 based on the type information obtained from the RFID reading system and the outputs of multiple object detection sensors 11. To this end, the control device 30 obtains the reading results for each coin configuration area from the RFID reading system and the detection results from each of the multiple object detection sensors 11. As a result, the control device 30 can obtain information stored in the RFID tag 111 and the presence or absence of a coin for each coin configuration area.

[0054] Figure 5 This table provides examples of the types of game coin status determined by the control device. The status determined by the control device 30 can be broadly categorized into five types: normal, warning, counterfeit, malfunction, and no game coins.

[0055] First, the control device 30 determines that the RFID tag 111 is damaged or not built into the game coin configuration area when the object detection sensor 11 detects game coins but the RFID tag 111 cannot be read normally by the RFID reading system.

[0056] More specifically, firstly, if the object detection sensor does not detect any game coins, the control device 30 determines that there are no game coins in the game coin configuration area.

[0057] Furthermore, the control device 30 is configured to determine that the data stored in the RFID tag 111 is corrupted when some information is read from the RFID tag 111 but the information cannot be interpreted (e.g., identification information can be obtained, but other information cannot be obtained), and to determine that the RFID tag 111 is completely faulty or not built into the RFID tag 111 when no information is read from the RFID tag 111.

[0058] Furthermore, if the identification information read by the RFID reading system is not stored in the storage device 40, the control device 30 determines that the game coin is counterfeit. In this case, it is suspected that the RFID tag 111 embedded in the game coin 110 may not be a legitimate RFID tag.

[0059] For game coins whose identification information read by the RFID reading system differs from the type information of adjacent game coins on both sides of the column, the control device 30 determines them to be counterfeit. For game coins at both ends of each column, since there are no adjacent game coins on both sides, if the identification information read by the RFID reading system differs from the identification information of adjacent game coins in the column, and the identification information of that adjacent game coin is the same as the identification information of its other adjacent game coins, the control device 30 determines that the game coin at that end is counterfeit.

[0060] Furthermore, if the identification information read by the RFID reading system has no specified relationship with the type information of other game coins 110 adjacent to each other in the column direction (for example, if a row is compared with the row above it, the amounts of the two rows are the same or the amount of the row below is greater than the amount of the row above), the control device 30 determines that the game coin 110 is counterfeit.

[0061] In this embodiment, when game coins are placed in the respective game coin configuration areas of the mounting platform 10, there is a rule that game coins of the same type with smaller amounts are placed in the upper row. Therefore, as described above, when adjacent game coins of different types are in the same row, or when the amount of game coins in the lower row is smaller than the amount of game coins in the upper row, or the amount of game coins in the upper row is larger than the amount of game coins in the lower row, it is suspected that the RFID tag 111 built into the game coin 110 is a legitimate RFID tag, but the appearance of a legitimate game coin 110 has been altered, or a legitimate game coin 110 RFID tag 111 has been implanted into another legitimate game coin 110.

[0062] For game coins 110 in game coin configuration areas where RFID tag 111 reading is unstable, the control device 30 determines that the RFID tag 111 reading is unstable. To make this determination, the RFID reading system can change the strength of the radio wave or even the magnetic field used to read the RFID tag 111 for each game coin configuration area. For game coins in game coin configuration areas that can be read when the intensity of the radio wave or magnetic field is increased but cannot be read when the intensity of the radio wave or magnetic field is decreased, the control device 30 determines that the RFID tag 111 reading is unstable.

[0063] Information about unstable, malfunctioning, suspicious, and abnormal game currency is pre-stored in a database and shared. For example, if game currency is determined to be unstable when read from the game currency tray (a location other than the display stand 10), it is stored in the database. When it is read from the display stand 10, the database information can predict that it is an unstable game currency being read. Information about unstable, malfunctioning, suspicious, and abnormal game currency is pre-listed in the database as a blacklist. When game currency information is read, if it matches the information on the blacklist, an alarm can be triggered.

[0064] If a game coin in the storage device 40 is not in an effective game coin configuration area and its activation state is associated with the identification information read by the RFID reading system, the control device 30 determines that the game coin is not in an effective state.

[0065] The control device 30 determines that game coins that are not in any of the defined problem states are in a normal state.

[0066] Return to Figure 1 The display device 20 consists of a display panel having pixels arranged in a matrix. Its display screen shows a zone display area 21 that represents the result of the status determination according to the configuration area of ​​each game coin, and a summary display area 22 that represents the summary value of the determination result.

[0067] Figure 6 This diagram illustrates an example of the use of the inspection system 101 according to the first embodiment of the present invention. In this example, five 10-point game coins are placed in the first row, three 50-point game coins are placed on the left side of the second row, four 100-point game coins are placed on the left side of the third row, three 1000-point game coins are placed on the left side of the fourth row, and five 1000-point game coins are placed on the left side of the fifth row.

[0068] like Figure 6As shown, in this embodiment, when placing game coins one by one into the respective game coin placement areas of the placement platform 10, the game coins are arranged in such a way that the type (amount) is the same in the same row and the amount increases (or is equal) as you move down to the next row. The person performing the inspection places the game coins into each game coin placement area while confirming the appearance of the game coins, that is, the amount marked on the front and back of the game coins.

[0069] In this example, the 10-point game coin located in area number 3 is a game coin without a built-in RFID tag 111; the 50-point game coin located in area number 6 is a game coin with a faulty RFID tag 111; the 1000-point game coin located in area number 17 is a game coin whose identification information stored in the RFID tag 111 is not stored in the storage device 40; and the 1000-point game coin located in area number 24 is a game coin with a 10-point RFID tag but appears to be a game coin with a 1000-point appearance, which is a game coin whose appearance has been tampered with.

[0070] Regarding area codes 3 and 6, although the object detection sensor 11 detected the game coins, the RFID reading system did not read the information. Therefore, it was determined that the RFID tag 111 was faulty or that the game coins did not contain the RFID tag 111.

[0071] Such errors are indicated in the corresponding area number of the area displayed in zone 21. Specifically, the area is displayed in red, and the text "RFID tag 111 fault" or "game coin without RFID tag 111" is displayed.

[0072] For area number 17, it is determined that the object detection sensor 11 detected a game coin and the RFID reading system read the RFID tag 111, but its identification information was not stored in the storage device 40. In this case, the error is displayed according to the corresponding area number of area 21. Specifically, this area is displayed in orange, and the RFID tag 111 and its identification information are displayed as "not registered." It should be noted that in this case, even if the amount of the game coin can be determined, the amount is not displayed.

[0073] For area number 24, it is determined that the object detection sensor 11 detected a game coin and the identification information read from the RFID tag 111 is stored in the storage device 40. However, the amount information associated with this identification information in the storage device 40 is inconsistent with the amount of the game coins on both sides. Specifically, the amount of game coins on both sides (area number 23 and area number 25) is 1000 points, but the amount information associated with the identification information read from the RFID tag 111 of area number 24 is 10 points.

[0074] Such situations may occur, for example, by altering the appearance of a legitimate 10-point game coin to disguise it as a 1000-point game coin, or by using the RFID tag 111 of a legitimate 10-point game coin to create a counterfeit 1000-point game coin. The dealer visually confirms the discrepancy between the information based on the RFID tag 111 and the appearance, and determines whether the dealer has placed the coin incorrectly. If incorrect, the coin can be replaced.

[0075] In this case, the error is indicated in the area corresponding to the area number in the zone display area 21. Specifically, the area is displayed in orange, or the text indicates that the game coin is counterfeit. It should be noted that, in this case, the amount information associated with the identification information read from the RFID tag 111 is displayed in the area corresponding to the area number in the zone display area 21.

[0076] It should be noted that in this embodiment, the identification information read from the RFID tag 111 is used and referenced to the storage device 40 to determine the amount information associated with the identification information and compare it with the game coins on both sides. However, as an alternative or on this basis, it is possible to determine whether the amount information read from the game coins is different from the game coins on both sides.

[0077] The summary results of reading and judging multiple game coin configuration areas are displayed in summary display area 22. Figure 7 To indicate Figure 6 The example diagram shows a summary display area. Figure 6 and Figure 7 In the example, in the summary display area 22, the game coins that are judged to be normal are 4 game coins of 10 points, 2 game coins of 50 points, 4 game coins of 100 points, and 6 game coins of 1000 points. Therefore, the subtotal of each amount is shown (40 game coins of 10 points, 100 game coins of 50 points, 400 game coins of 100 points, and 6000 game coins of 1000 points) and the total amount of 6540 points.

[0078] Furthermore, for game currency 110 that is considered cheating or abnormal, the content and number of instances of cheating or abnormality are displayed. Figure 6 and Figure 7 In the example, it is shown that 2 game coins were determined to be faulty or without RFID tag 111, 1 game coin was determined to be unregistered, and 1 game coin was determined to be counterfeit.

[0079] Figure 8 Figures illustrate other usage examples of the inspection system 101 according to the first embodiment of the present invention. Figure 8 In the example, only one 100-point coin is placed. In this case, it is impossible to compare the 100-point coin with the amount of other coins in the same row. However, for zone number 11, the row above the row containing this zone (row 3) (row 2) has a 50-point coin, and the row below the row containing this zone (row 3) (row 4) has a 1000-point coin.

[0080] For region number 11, the control device 30 uses its relationship with the amounts read in the previous and next rows to determine whether the amount of game coins at region number 11 meets the aforementioned specified relationship. Figure 8 In the example, in area number 11, the amount associated with the identification information read by the RFID reading system in storage device 40 is 10 points. In this case, the relationship between this amount and the next row (row 4) is satisfied because the amount in that row is smaller, but the relationship between this amount and the previous row (row 2) is not satisfied because the amount in that row is smaller. Therefore, control device 3 determines that the amount of "10 points" determined in area number 11 is abnormal, and identifies the game coin as counterfeit.

[0081] Figure 9 To indicate Figure 8 The example diagram shows a summary display area. Figure 8 and Figure 9 In the example, in the summary display area 22, the game coins that are judged to be normal are 5 game coins of 10 points, 3 game coins of 50 points, 0 game coins of 100 points, and 7 game coins of 1000 points. Therefore, the subtotal of each amount is shown (50 game coins of 10 points, 150 game coins of 50 points, 0 game coins of 100 points, and 7000 game coins of 1000 points) and the total amount of 7200 points.

[0082] In addition, for game currency 110 that is considered cheating or abnormal, the content and quantity of the cheating or abnormality are displayed. Figure 8 and Figure 9 In the example, one game coin was identified as counterfeit.

[0083] It should be noted that in the above embodiment, a rule is set such that game coins 110 of the same amount are placed in rows, with smaller amounts of game coins 110 placed in the rows above. The dealer places the game coins 110 one by one in the game coin placement area according to this rule by visual inspection. However, as an alternative, a rule can also be set such that game coins 110 of the same amount are placed in rows, with larger amounts of game coins 110 placed in the rows above, or game coins 110 of the same amount are placed in columns, with smaller amounts of game coins 110 placed in the leftmost columns, or game coins 110 of the same amount are placed in the rightmost columns.

[0084] Furthermore, in the above embodiment, a rule is set in which game coins 110 of the same amount are placed in rows and game coins 110 of smaller amounts are placed in the upper rows. The control device 30 determines that game coins 110 that are adjacent on both sides but have different amounts are counterfeit. However, as an alternative, when there are multiple amounts of game coins 110 in the same row, the majority amount can be determined to be real and the minority amount can be determined to be counterfeit.

[0085] In this case, the control device 30 first determines whether the same row contains multiple amounts of game coins 110. Furthermore, if multiple amounts of game coins 110 exist, it determines which amount is more prevalent and which is less prevalent, thereby classifying a particular amount of game coins 110 as counterfeit. Moreover, even when a rule is set such that the same amount of game coins 110 is placed on the entire platform 10, when multiple amounts of game coins 110 are present, the majority amount can be classified as genuine, and the minority amount as counterfeit.

[0086] Furthermore, a rule can be set such that the same amount of game coins 110 are placed in the same row and the size relationship of the game coins 110 placed in each row is arbitrary. In this case, the control device 30 can use the amount of game coins 110 in the leftmost column (first column) of each row as a benchmark to determine whether the amount of game coins 110 in the second column and beyond in each row is the same as the amount of game coins 100 in the first column.

[0087] Figure 10 This diagram illustrates an inspection system according to a variation of the first embodiment of the present invention. In this example, the amount of coins to be placed in each of the multiple coin placement areas of the platform 10 is pre-allocated. Each coin placement area on the placement surface 120 of the platform 10 is printed with a number indicating the amount of coins to be placed therein. The dealer or other casino staff place the coins one by one into each coin placement area according to this number.

[0088] When the amount information associated with the identification information read from each game coin configuration area in the storage device 40 is different from the amount allocated to that game coin configuration area, the control device 30 determines that the game coins in that game coin configuration area are counterfeit.

[0089] Figure 11 This diagram illustrates an example of the use of an inspection system based on a variation of the first embodiment of the present invention. In this example, the amount allocated to area number 24 is 1000 points, but the amount associated with the identification information read by the RFID reading system in the storage device 40 is only 10 points. That is, the amount determined based on the RFID tag 111 is different from the amount allocated to the game coin configuration area; therefore, the control device 30 determines that the game coin is counterfeit.

[0090] The dealer and other casino staff placed game token 110 in the game token storage area (area number 24) because it appeared to be worth 1000 points. Therefore, the value of game token 110, determined based on its appearance, did not match the value determined based on RFID tag 111, and was thus deemed counterfeit.

[0091] As described above, according to the first embodiment and variations of the inspection system of the present invention, multiple coin placement areas are provided on the placement platform 10, and coin-to-coin items are placed one by one in each coin placement area and inspected. Each coin placement area is provided with a reading antenna 121 for reading RFID tags 111 and an object detection sensor 11. The reading antenna 121 reads the RFID tags 111 of the coin-to-coin items 110 in each coin placement area, and the object detection sensor 11 detects the presence or absence of coin-to-coin items 110 in each coin placement area.

[0092] According to this structure, for a game coin configuration area that is detected by the object detection sensor 11 (where a game coin is placed) but the RFID tag 111 cannot be read, it can be determined that the RFID tag 111 of the game coin is faulty or that the game coin does not have a built-in RFID tag 111.

[0093] Furthermore, in the first embodiment, a storage device 40 is provided that stores identification information of game tokens used in the casino. The control device 30 determines whether the identification information read by the RFID reading system from each game token placement area is stored in the storage device 40. If the read identification information is not stored in the control device 30, the control device 30 determines that the game token 110 is not registered.

[0094] Furthermore, in the first embodiment, a set of rules is set for the configuration of the amount of game coins in the placement surface 120. The dealer or even the casino staff can identify the amount of the game coins from their appearance and place the game coins according to the rules, or pre-allocate the amount of game coins to be placed in each game coin placement area. The dealer or even the casino staff can identify the amount of the game coins from their appearance and place the game coins corresponding to the allocated amount in each game coin placement area.

[0095] The control device 30, by referring to the storage device 40, determines the amount associated with the identification information read by the RFID reading system, and determines whether the determined amount corresponds to the aforementioned rules and even the allocated amount. Thus, game coins whose apparent amount differs from the amount determined by the RFID tag 111 can be identified as counterfeit.

[0096] It should be noted that in the above embodiment, the RFID reading system reads identification information from the RFID tag 111 of the game coin 110, and the control device 30 determines the amount associated with the identification information by referring to the storage device 40, thereby determining the amount based on the RFID tag 111 of the game coin 110. However, based on this or as an alternative, the RFID reading system can read amount information from the RFID tag 111, and the control device 30 can determine the amount of the game coin 110 based on the amount information read by the RFID reading system. It should be noted that in this case, the storage device 40 can be omitted. Alternatively, when the amount of the game coin 110 is determined by the amount stored in the storage device 40, the amount information stored in the RFID tag 111 can be omitted.

[0097] In addition, the control device 30 can determine whether the amount information stored in the RFID tag 111 corresponds to the amount information in the storage device 40 associated with the identification information read from the RFID tag 111 (whether they represent the same amount), and determine whether the game coin 110 or even the RFID tag 111 is counterfeit or tampered with.

[0098] Further explanation Figure 5 The determination of each state is shown. The RFID reading system can change the strength of the radio wave or magnetic field emitted from the reading antenna 121 (hereinafter referred to as "antenna strength"). For each coin 110 placed in the coin configuration area of ​​the mounting platform 10, the RFID reading system changes the antenna strength and reads multiple times. For example, the RFID reading system reads with an antenna strength of two levels, strong and weak.

[0099] If the RFID tag 111 is read when the antenna strength is strong, but cannot be read when the antenna strength is weak, the control device 30 determines that the reading of the game coin 110 in the game coin configuration area is unstable.

[0100] Furthermore, as described above, the storage device 40 stores an activation state. When the activation state of the identification information read from the RFID tag 111 is invalid in the storage device 40 (e.g., not yet valid or invalidated (not activated)), the control device 30 determines that the game coin 110 is invalid.

[0101] Furthermore, while monitoring for cheating tokens and cheating activities is conducted in various settings within casinos, there are instances where tokens deemed suspicious are not definitively identified as cheating tokens. Additionally, there are situations where tokens involved in cheating activities should be used with caution afterward, even if they haven't been confirmed as counterfeit and are therefore set to unusable.

[0102] For such suspicious game tokens, unusable information can be pre-stored in the storage device 40 in association with the token's identification information. When the inspection system 101 reads the identification information through the RFID reading system, and the storage device 40 stores the identification information as unusable, the control device 30 determines that the game token is in an unusable state.

[0103] Furthermore, in the above embodiments, if no information can be read from the game coin 110, the control device 30 determines that the RFID tag 111 is faulty or missing. However, if some information is read from the RFID tag 111, it can be determined that the RFID tag 111 is present. But when the RFID tag does not store valid information, for example, if the TID (Tag ID) area of ​​the RFID tag 111 is readable, but the data in the EPC (Electronic Product Code) area or the user area is damaged, it can be determined that the RFID tag 111 (data) is faulty.

[0104] (Second Implementation) Figure 12 This diagram illustrates the structure of a system according to a second embodiment of the present invention. The system comprises multiple inspection systems 102 and a game currency management system 200. The multiple inspection systems 102 and the game currency management system 200 are communicatively connected via a communication network 300.

[0105] The game token management system 200 can be installed within a casino facility, using the Internet as a communication network 300, or it can be connected to multiple inspection systems 102 within the casino facility via the communication network 300. In the game token management system 200, information such as the amount of each game token, reading history, activation or deactivation status, information on unstable game tokens, and unusable information are updated in association with the identification information of each game token. This information is periodically shared with each inspection system 102 via the communication network 300. In the first embodiment, various information associated with the identification information is stored in the storage device 40. The control device 30 of each inspection system 101 refers to the storage device 40 within the same inspection system 101 to determine whether the identification information is registered, etc. However, in this embodiment, the inspection system 102 does not have a storage device 40. The control device 30 queries the game token management system 200 via the communication network 300 for the identification information read from the RFID tag 111 of the game token 110 by the RFID reading system, thereby determining whether the identification information is registered, etc.

[0106] It should be noted that each inspection system 102 may include a storage device 40. In this case, each inspection system 102 does not necessarily need to connect to the game currency management system 200 via the communication network 300 for every inspection; the control device 30 can access the storage device 40 to perform the inspection. Furthermore, in this case, the storage device 40 of each inspection system 102 is periodically updated via the game currency management system 200 through the communication network 300.

[0107] Figure 13 This is a diagram illustrating the structure of the inspection system 102 according to the second embodiment of the present invention. In the description of the inspection system 102 of this embodiment, elements having the same function as the inspection system 101 of the first embodiment are given the same numbers and their descriptions are omitted as appropriate.

[0108] The inspection system 102 includes a platform 10, a display device 20, a control device 30, and a camera 50. Furthermore, although... Figure 13 Although not shown in the diagram, the inspection system 102 has the same RFID reading system as the inspection system 101. The control device 30 in this embodiment has communication capabilities and communicates with the game coin management system 200. It should be noted that in this embodiment, the platform 10 has 16 game coin configuration areas arranged in 4 rows and 4 columns.

[0109] In the inspection system 102, no object detection sensor 11 is provided in each game coin placement area, but instead, a shooting device 50 with a shooting platform 10 is provided. The shooting device 50 is a camera system consisting of an optical system such as a lens, an image sensor, an image processing device, etc.

[0110] The imaging device 50 captures images of the game coins 110 placed in the coin arrangement areas of the platform 10 from above, and generates images. The camera 20 generates a panchromatic image. It should be noted that the imaging device 50 is not limited to one unit; two or more units may be used. Furthermore, when information such as identification information is marked on the game coins 110 using invisible inks such as ultraviolet-reactive ink or infrared-absorbing ink, the imaging device 50 is equipped with an ultraviolet lamp or infrared lamp for visualizing such invisible inks.

[0111] The control device 30 has an image recognition function that identifies game coins in each coin placement area and determines their type by performing image recognition on captured images. That is, the control device 30 also functions as an image recognition device. Machine learning techniques such as neural networks and SVMs can be used for this image recognition. In these machine learning methods, the game coin 110 is designed and learned to be recognizable regardless of its rotation angle. Furthermore, in image recognition, a difference image can be generated based on images of the mounting surface 120 with and without game coins 110, thereby extracting and recognizing the game coin 110. Additionally, the difference image can be used to detect only the presence or absence of the game coin 110, checking the game coin 110 in the same manner as in the first embodiment.

[0112] The control device 30 can use image recognition to identify the number displayed on the game coin 110, thereby determining the amount of the game coin. Alternatively, the control device 30 can extract features from the entire image of the game coin through self-learning and identify its amount without specifying any features for identification. In addition to displaying a number indicating the amount, the game coin 110 also displays colors or patterns that vary according to the amount; therefore, these colors or patterns can also constitute features for determining the amount.

[0113] It should be noted that, as described above, when the identification information is marked on the game coin 110 using visible or invisible ink, the control device 30 can also read the identification information based on the captured image. In this case, identification can also be performed using neural networks such as deep learning.

[0114] The display device 20 includes a zone-based lighting unit 23 and a liquid crystal display unit 24. The zone-based lighting unit 23 is equipped with multiple lights arranged to correspond to the coin placement areas on the mounting surface 120 of the platform 10. The lights are equipped with tri-color LED light-emitting elements and can emit light of any color.

[0115] In this embodiment, the status of the game coins determined by the control device 30 is indicated by the lighting color of the lights in the zone-based lighting section 23. In this embodiment, the control device 30 determines each game coin placement area to be in any of the following states: "normal," "caution," "counterfeit," "malfunction," or "no game coins," and lights up the lights in green (normal), yellow (caution), orange (counterfeit), and red (malfunction), respectively. The lights do not light up when there are no game coins.

[0116] The game coin management system 200 functions as a database server, storing the same data as that stored in the storage device 40 of the first embodiment. Specifically, the game coin management system 200 stores identification information, amount information, activation status, read history, and unusable flags for all game coins 110 used in the casino, and can determine the amount information, activation status, etc., associated with the identification information using the identification information as a keyword.

[0117] When the game coin 110 is unstable, invalid, or unusable, the control device 30 determines it to be in a "caution" state, causing the area number light of the game coin to illuminate yellow. It should be noted that the flashing pattern of the yellow light can be changed according to the differences between unstable, invalid, and unusable states. For example, it can be illuminated when unstable and flashed when invalid and unusable; the flashing pattern can be different for invalid and unusable states.

[0118] It should be noted that if the reading of the RFID tag 111 of the game coin 110 is unstable, the control device 30 can store information indicating this situation in association with the identification information in the game coin management system 200. In this way, for a game coin with unstable information stored in the game coin management system 200, when the control device 30 later retrieves the identification information from the RFID reading system, it uses this identification information as a keyword to query the game coin management system 200, thereby enabling the control device 30 to understand the situation of unstable reading of the RFID tag 111 of the game coin 110.

[0119] Furthermore, if the amount identified from the captured image using image recognition does not match the amount obtained by referring to the game coin management system 200 using the identification information read from the RFID tag 111 by the RFID reading system as a keyword, the control device 30 determines that the appearance of the game coin has been tampered with. Additionally, if the identification information read from the RFID tag 111 by the RFID reading system is not stored in the game coin management system 200, the control device 30 determines that the identification information of the RFID tag 111 of the game coin is not registered.

[0120] If the control device 30 determines that the appearance of the game coin 110 has been tampered with or that the RFID tag 111 is not registered, it will determine that the game coin 110 is "counterfeit" and illuminate the area code light of the game coin in orange. It should be noted that the flashing pattern of the orange light can be changed according to the difference between appearance tampering and unregistered identification information. For example, it can be set to illuminate when the appearance has been tampered with and flash when the RFID tag is not registered.

[0121] If the image recognition result of the captured image shows that the game coin configuration area has been identified, but no reading result of RFID tag 111 is obtained from the RFID reading system, the control device 30 determines that the RFID tag 111 of the game coin 110 in the game coin configuration area is faulty or that the game coin 110 in the game coin configuration area does not have an RFID tag 111, and determines that the status of the game coin 110 is "faulty", and causes the light of the area number of the game coin 110 to light up red.

[0122] If the image recognition result of the captured image shows that no game coin configuration area is identified, the control device 30 determines that there are "no game coins" and does not light up the area number light of that game coin configuration area.

[0123] As described above, the control device 30 has a lamp control function that controls the lighting of each lamp in the zone lighting section 23 according to the determination result.

[0124] The LCD display unit 24 displays a summary of the inspection results for each of the multiple coin configuration areas. Specifically, the LCD display unit 24 displays the number of coins judged as "normal" and the total number of coins judged as "caution," "counterfeit," or "malfunctioning," that is, the number of cheating or abnormal coins.

[0125] Figure 14 This figure illustrates an example of the use of the inspection system according to the second embodiment of the present invention. In this example, the control device 30 determines that the reading of the game coin 110 in area number 3 is unstable and is in a "caution" state, and causes the light in area number 3 of the area-by-area lighting section 23 to light up yellow.

[0126] Furthermore, regarding area number 8, the control device 30 identifies a game coin with 100 points from the captured image and receives from the RFID reading system that the RFID tag 111 was not read from the game coin 110 in area number 8. It then determines that the RFID tag 111 is in a "faulty" state and turns on the light for area number 8 in the area lighting section 23 red.

[0127] Furthermore, for area number 9, the control device 30 acquires the identification information read by the RFID reading system and uses this identification information as a keyword to query the game coin management system 200 to obtain the amount information associated with the identification information, namely 10 points. On the other hand, for area number 9, the control device 30 identifies the game coin 110 as a game coin with 100 points from the captured image. The amount information (10 points) stored in the game coin management system 200 is different from the amount information (100 points) identified from the captured image. Therefore, the control device 30 determines that the game coin 110 is a "counterfeit" game coin with altered appearance and lights up the light for area number 9 in the area-by-area lighting section 23 to orange.

[0128] Furthermore, for area number 11, the control device 30 acquires the identification information read by the RFID reading system and uses this identification information as a keyword to query the game coin management system 200. If the control device 30 receives a result from the game coin management system 200 indicating that the identification information is not registered, it determines that the game coin 110 is a "counterfeit" game coin using an unregistered RFID tag and illuminates the light for area number 11 on the zone-by-zone lighting section 23 in orange.

[0129] Furthermore, the image recognition results for images captured in areas 1, 2, 4-7, 10, and 12-14 show that game token 110 was identified and did not exhibit any of the aforementioned problems. Therefore, the control device 30 classifies these game tokens 110 as "normal" and illuminates the lights for areas 1, 2, 4-7, 10, and 12-14 of the zone-based lighting unit 23 in green. It should be noted that the image recognition results for images captured in areas 15 and 16 show that game token 110 was not identified. Therefore, the control device 30 does not illuminate the lights for areas 15 and 16 of the zone-based lighting unit 23.

[0130] Figure 15 This diagram illustrates a modified example of the display of the liquid crystal display unit according to the second embodiment of the present invention. (See diagram below.) Figure 15 As shown, the LCD display unit 24 can display the number and subtotal of each type of normal game token 110, and the total amount of normal game token 110. Furthermore, for cheating or abnormal game token 110, it can display the area code and the cheating or abnormal content.

[0131] exist Figure 14 and Figure 15 In the example, as mentioned above, the determination area number 3 is unstable, the determination area number 8 is RFID faulty or has no RFID, the determination area number 9 is tampered with, and the determination area number 11 is RFID tag 111 not registered. Therefore, each of these contents is displayed on the liquid crystal display unit 24.

[0132] As described above, the inspection system 102 of this embodiment identifies the amount of game coins 110 by photographing them placed on the mounting platform 10 using the photographing device 50. Therefore, any amount of game coins 110 can be placed in multiple game coin placement areas without having to arrange the game coins 110 according to predetermined rules or even pre-allocated amounts to the mounting platform 10, as is done in the inspection system 101 of the first embodiment.

[0133] It should be noted that in this embodiment, the control device 30 can use the identification information marked on the surface of the game coin 110 for determination. For example, the control device 30 can be configured to read the identification information marked on the surface of the game coin 110 from the captured image and query the game coin management system 200. In this case, the RFID reading system can be omitted.

[0134] Alternatively, the identification information obtained from the captured image can be compared with the identification information obtained by the RFID reading system to determine the authenticity of the game coin. If the two are different, the control device 30 determines that either the appearance of the game coin 110 has been tampered with or an unregistered RFID tag 111 has been used.

[0135] Furthermore, if no problems are found in the inspection system 102, the control device 30 determines that the game coin is normal.

[0136] It should be noted that in this embodiment, the game coin 110 stores identification information in an RFID tag 111, and the identification information is printed using ink, in a manner other than RFID tagging. Furthermore, the game coin management system 200 stores the reading history of the RFID reading systems of each inspection system 102. That is, the game coin management system 200 stores which inspection system 102 read what kind of identification information when.

[0137] Based on this structure, when the control device 30 determines that the RFID tag of the game coin is damaged or does not have an RFID tag built in, it can use identification information in a manner other than RFID tags to obtain the game coin's reading history stored in the game coin management system 200. Therefore, it is possible to track the extent to which the RFID tag 111 has been correctly read, and thus detect cheating.

[0138] In the event of RFID malfunction or the absence of an RFID tag, it is impossible to know the identification information that should be deactivated. Therefore, identification information that exists in a manner other than RFID tags can be found, thereby deactivating that identification information. For game coins that do not have RFID tags 111 because the normal RFID tag 111 has been removed, there is a risk of using the removed RFID tag 111 to counterfeit another game coin. Therefore, identification information determined in a manner other than RFID tags will be deactivated.

[0139] (Third Implementation) Figure 16 The diagram does not show the structure of the inspection system according to the third embodiment of the present invention. The inspection system 101 of the first embodiment described above is a stand-alone system that integrates a stage 10, a display device 20, a control device 30, and a storage device 40, and can be used even without being connected to a communication network.

[0140] Furthermore, the inspection system 102 in the second embodiment is a networked system in which the game coin management system 200, which is equivalent to the storage device 40, is connected to multiple inspection systems 102 via a communication network. In the inspection system 103 of this embodiment, the platform 10, the display device 20, the control device 30, and the game coin management system 200, which is equivalent to the storage device 40, are each configured as separate devices.

[0141] In addition, Figure 16 In the example, for game token 110 in area number 7, it appears to be a 50-point token, but the amount obtained by reading the RFID tag 111 through the RFID reading system is 100 points. In this case, for area number 7, the display device 20 displays both the 50-point and 100-point values ​​identified.

[0142] Furthermore, for area number 8, the game coin 110 does not have an RFID tag 111, so the amount cannot be determined based on the RFID tag 111, but the camera 50 identifies 100 points based on appearance. Therefore, the display device 20 displays the meaning that the RFID tag 111 cannot be read and the appearance is 100 points. That is, in this embodiment, the content identified by the camera and the content identified by the RFID reading system are directly displayed.

[0143] Furthermore, in this embodiment, a personal computer can be used as a control device 30, and a monitor of the personal computer can be used as a display device 20.

[0144] Figure 17This diagram illustrates a variation of the inspection system according to the third embodiment of the present invention. In this example, the inspection system 103 includes a platform 10 with a built-in RFID reading system, a tablet computer 600, and a game coin management system 200. That is, compared to the third embodiment described above, the display device 20, the control device 30, and the imaging device 50 are implemented by a single tablet computer.

[0145] The tablet computer 600 communicates with the RFID reading system of the platform 10 via wired or short-range wireless means. Furthermore, the tablet computer 600 connects to the communication network 300 via a wireless router and communicates with the game coin management system 200.

[0146] In this example, all the functions of the control device 30, such as image recognition, judgment, and display, can be packaged into an application and provided to the tablet computer 600.

[0147] (Fourth Implementation) Figure 18 This diagram illustrates the structure of the inspection system according to the fourth embodiment of the present invention. In the inspection system 104 of this embodiment, a mounting surface 120 is provided on the tabletop of the game table 500 near the dealer's position. The mounting surface 120 is divided into 4 rows and 5 columns of coin placement areas by lines. Furthermore, a display device 20 is embedded in the tabletop near the mounting surface 120, and a control device 30 is provided inside the game table 500.

[0148] Each control device 30 of the multiple game tables 500 is communicatively connected to the game coin management system 200 via a communication network 300. An RFID reading system reads the RFID tags 111 of the game coins 110 placed in the respective game coin configuration areas on the mounting surface 120. It should be noted that a camera can be mounted on the ceiling to identify the game coins.

[0149] The control device 30 uses the identification information read from the RFID tag 111 by the RFID reading system as a keyword to query the game currency management system 200 and obtain the amount information associated with the identification information. Then, similar to the first embodiment, it can be checked whether the determined amount follows the rule that the amount is the same in each row and the amount decreases as you move up to the next row.

[0150] Alternatively, the control device 30 can determine whether the game coins 110 in each game coin configuration area are normal based on whether the amount information read by the RFID reading system from the RFID tag 111 of the game coin 110 is consistent with the amount obtained from the game coin management system 200.

[0151] In this embodiment, the lines dividing the game coin configuration areas on the mounting surface can be emitted from below the tabletop via LED lights when needed to indicate the game coin configuration areas.

[0152] Furthermore, in this embodiment, the coin tray 501, which holds the dealer's coins, may be equipped with an RFID reading system. The RFID reading system of the coin tray 501 can cooperate with the RFID reading system of the inspection system 104.

[0153] Figure 19 This diagram illustrates a variation of the inspection system according to the fourth embodiment of the present invention. In this example, the tabletop of the game table 500 has a coin placement area with five coins arranged in a row. The dealer places the same amount of coins 110 in this row. This coin placement area may include a monitor or a light.

[0154] The RFID reading system reads the monetary information stored in the RFID tags 111 of each game coin 110 placed in multiple game coin configuration areas. The control device 30 obtains the reading results from the RFID reading system. Even if there is one game coin 110 with a different monetary value among the multiple monetary values ​​obtained from the RFID reading system, that is, if not all game coins 110 have the same monetary value, the control device 30 determines that there is a counterfeit game coin 110 among the multiple game coins 110.

[0155] Furthermore, if only a few (in this example, five) RFID tags 111 in the game coin configuration area are not read, the control device 30 also determines that there are RFID tag 111 faults or no RFID tag 111 among the multiple game coins 110.

[0156] In the inspection system 104 of this example, the display device 20 has three lights. The lighting and extinguishing of each light are controlled by the control device 30. The control device 30 is configured to illuminate the green normal light when the five game coins 110 are normal, illuminate the orange counterfeit light when counterfeit game coins 110 are detected, and illuminate the red fault light when RFID tag 111 is detected as faulty or game coins 110 without RFID tag 111 are detected.

[0157] According to this example, the area occupied by the inspection system 104 on the game table 500 can be minimized, and the impact of the dealer on other operations can be minimized.

[0158] (Fifth implementation method) Figure 20 This diagram illustrates the structure of the inspection system according to the fifth embodiment of the present invention. Figure 20As shown, in the inspection system 105 of this embodiment, each game coin placement area of ​​the platform 10 is provided with a display device 20 for displaying the judgment result. In this embodiment, the display device 20 provided in each game coin placement area is a light whose color indicates the judgment content, but as an alternative or based on this, a liquid crystal display panel for each game coin placement area can be provided.

[0159] The inspection system 105 inspects the game coins 110 in the same manner as the inspection system 101 of the first embodiment, and displays the determination result of the game coins in each game coin configuration area by the color of the light in the corresponding game coin configuration area.

[0160] (Sixth Implementation Method) Figure 21 This diagram illustrates the structure of the inspection system according to the sixth embodiment of the present invention. Figure 21 As shown, the inspection system 106 of this embodiment, compared with the inspection system 101 of the first embodiment, has multiple game coin configuration areas 16 on the mounting platform 10.

[0161] The multiple game coin configuration area 16 is equipped with a reading antenna (not shown), which is used to read the RFID tags 111 of the multiple game coins 110 placed in the multiple game coin configuration area 16. It should be noted that, similar to the first embodiment, an interference antenna may be provided corresponding to the reading antenna, or a shield may be provided so that the reading antenna does not read the RFID tags 111 of the game coins 110 placed in adjacent multiple game coin configuration areas.

[0162] When dealers and other casino staff use the inspection system 106 of this embodiment, they first stack multiple (e.g., 5 per row) of game coins 110 that should be placed in the game coin placement area in multiple game coin placement areas 16 before placing the game coins 110 one by one in the game coin placement area.

[0163] The reading antennas of multiple game coin configuration areas 16 read the RFID tags 111 of multiple game coins 110 placed in the multiple game coin configuration areas 16 together, and display the results on multiple reading result display units 25.

[0164] Figure 22 This diagram illustrates an example of the use of the inspection system according to the sixth embodiment of the present invention. In this example, five 100-point game coins are placed in multiple coin placement areas 16. Multiple read result display units 25 display the results read by the RFID reading system from the multiple coin placement areas 16.

[0165] The dealer and other casino staff (hereinafter referred to as "the dealer") take out 5 tokens 110 and place them in the multiple token placement area 16. At this time, the dealer visually confirms the amount of 5 tokens 110. Typically, the same amount of 5 tokens 110 is placed in the multiple token placement area 16.

[0166] Multiple reading result display units 25 display the contents read by the RFID reading system from multiple coin placement areas 16, and the dealer confirms this content. If the result differs from the content confirmed visually, the dealer places five coins 110 one by one into the coin placement area for further inspection.

[0167] Since placing the game coins one by one is time-consuming, multiple game coins can be placed together. The dealer then checks the multiple read result displays 25, and if all game coins are confirmed to be normal, the check ends. This reduces the time spent on the check. If multiple game coins are placed and abnormal game coins are confirmed, the game coins can be placed one by one in the game coin placement area to identify the abnormal game coins.

[0168] It should be noted that in this embodiment, the number of game coins 110 placed in the multiple game coin configuration areas 16 is confirmed, but alternatively, only the number of coins can be determined. In this case, the dealer visually confirms the specified number of coins, and in the multiple game coin configuration areas 16, the multiple read result display units 25 display the number of RFID tags 111 read as the read result.

[0169] Based on this structure, it is also possible to detect whether there are game coins 110 with faulty RFID tags 111 or without RFID tags 111 among the multiple game coins 110. Suppose that there are game coins 110 with faulty RFID tags 111 or without RFID tags 111, the number of game coins 110 placed in the multiple game coin configuration area 16 is different from the number displayed in the multiple read result display units 25.

[0170] However, at this stage, it was unclear which of the multiple game coins (110) was problematic. Therefore, these multiple game coins were placed one by one in adjacent game coin configuration areas for inspection.

[0171] It should be noted that the multiple coin storage areas 16 can be enlarged to, for example, a size that can hold approximately five coin boxes that can hold 20 coins each. In this case, five coin boxes (totaling 100 coins) are placed in the multiple coin storage areas 16, and the results are displayed on multiple reading result display units 25. The inspector places multiple coin boxes (each holding 20 coins) in the multiple coin storage areas 16. If the reading result matches the visually confirmed coin count (e.g., 100 points of coins consist of 20 coins x 5 boxes, totaling 100 coins), the inspection ends. If they do not match, the coin boxes can be placed one by one in the multiple coin storage areas 16 for inspection. Furthermore, if a problematic coin box is identified, the box can be opened, and the coins 110 can be removed and placed one by one in the coin storage area of ​​the platform 10 for inspection.

[0172] Alternatively, the control device 30 can determine whether a predetermined number (e.g., 100) of the same amount of game coins 110 exist in the multiple game coin configuration areas 16, and display only the result of whether it is qualified or not on the multiple read result display units 25. Furthermore, the control device can determine only whether the amounts of the multiple game coins 110 read in the multiple game coin configuration areas 16 are all the same, and display only the result of whether it is qualified or not on the multiple read result display units 25. It should be noted that the multiple game coin configuration areas 16 and the multiple read result display units 25 can be separately configured from the platform 10.

[0173] (Seventh Implementation) Figure 23 This diagram illustrates the structure of the inspection system according to the seventh embodiment of the present invention. Compared to the inspection system of the first embodiment, the inspection system 107 of this embodiment does not include a storage device 40, and like the second embodiment, it can be used without communicating with the game coin management system 200. Furthermore, the control device 30 does not perform the aforementioned inspections or even determinations.

[0174] The RFID reading system of the mounting platform 10 reads the amount information from the game coins 110 configured in each game coin configuration area. The control device 30 displays the amount information read by the RFID reading system in the area display area 21. In addition, the control device 30 summarizes the amount information read by the RFID reading system from the RFID tags 111 of the game coins 110 in each game coin configuration area and displays the summary result in the summary display area 22.

[0175] Figure 24This diagram illustrates an example of using the inspection system according to the seventh embodiment of the present invention. In this example, the dealer visually confirms that 100-point game coins are placed in all the coin placement areas. The area display area 21 shows that 100-point game coins have been read in all area numbers, and the summary display area 22 shows that 25 100-point game coins have been read. By comparing the appearance of the game coins 110 placed on the placement platform 10 with the displays in the area display area 21 and the summary display area 22, the dealer can confirm that all 25 game coins 110 are in good condition.

[0176] Figure 25 The diagram illustrates another example of the use of the inspection system according to the seventh embodiment of the present invention. In this example, the game coin 110 placed in zone number 14 has 10 points stored in its RFID tag 111 as amount information, but appears to be a 100-point game coin. The dealer determines that the game coin 110 is a 100-point game coin and places it in zone number 14 along with other 100-point game coins. In the zone display area 21, all zone numbers should normally display the same 100 points, but only zone number 14 displays 10 points. By checking the game coin 110 placed on the platform 10 and the display in the zone display area 21, the dealer can determine that the game coin 110 in zone number 14 is counterfeit.

[0177] Furthermore, the game coin 110 placed in zone number 17 does not have a built-in RFID tag 111. Therefore, zone number 17 does not display a numerical value in the zone display area 21. By checking the game coin 110 placed on the platform 10 and the display in the zone display area 21, the dealer can determine that the game coin 110 in zone number 17 is a faulty game coin.

[0178] Furthermore, the summary display area 22 should have shown 25 100-point game tokens. However, due to the presence of a counterfeit game token 110 in area number 14 and a faulty game token 110 in area number 17, only 23 100-point game tokens and 1 10-point game token were displayed, totaling 24. By checking the game token 110 placed on the platform 10 and the display in the summary display area 22, the dealer can determine that there is one counterfeit game token 110 and one faulty game token 110.

[0179] As described above, in the inspection system 107 of this embodiment, the control device 30 does not perform inspection or judgment, but the display device 20 displays information for the dealer to make a judgment. In particular, if the same amount of game coins 110 are placed in the game coin placement area, counterfeit or faulty game coins can be easily detected by checking the display device 20. For example, if different colors are added to the zone display area 21 according to each type (amount) of the identified game coins 110, the presence of game coins 110 with different amounts than their appearance becomes immediately apparent.

[0180] (Eighth Implementation) Figure 26A This is a partial cross-sectional view of the mounting platform of the inspection system according to the eighth embodiment of the present invention. Figure 26B This is a partial top view of the mounting platform of the inspection system according to the eighth embodiment of the present invention. In the mounting platform 10 of this embodiment, each coin placement area 220 is provided with a stop 221 for placing coins 110 one by one into each coin placement area 220. The stop 221 is provided vertically at the left end of each coin placement area 220. Each stop 221 has: a wall 221w, which stands vertically from the mounting surface 120 at the left end of the coin placement area 220; and a slope 221s, which slopes gently from the wall 221w toward the center of the coin placement area 220. The height of the wall 221w is designed to be the same as or slightly lower than the thickness of the coin 110. Grooves 222 without stop 221 are formed between adjacent stop 221s in the vertical direction.

[0181] Figure 27A and Figure 27B This diagram illustrates an example of using the inspection system according to the eighth embodiment of the present invention. When the inspector places the game coins 110 one by one into the game coin placement areas 220 of the platform 10, they use their fingers to pick up a stack of five game coins 110 of the same amount and, while moving their hand from left to right, place these game coins 110 one by one into the respective game coin placement areas 220 in the row where they should be placed. Figure 27A As shown, the bottommost of the multiple game coins 110 is pressed against the wall 221w of the stop 221 and cannot move further to the left, as... Figure 27B As shown, only the second and above game coins 110 from the bottom are moved to the right by the hand. Thus, game coins 100 can be smoothly placed row by row in the game coin placement areas 220 of the platform 10.

[0182] By utilizing the stop 221, the coins 110 arranged in the coin arrangement areas 220 can be easily removed from the stand 10. When removing the coins 110, the inspector moves their hand from right to left along the groove 222 with one finger, removing them row by row. While pushing the right end of the coin 110 with their finger, they move it to the left, climbing the ramp 221s from the left end. When the left end of the coin pushed to the left reaches the end of the ramp 221s, it covers the next coin 110, which is then pushed to the left along with another coin. By repeating this operation, the inspector can stack multiple coins 110 arranged side-by-side in a row by simply moving their finger along the groove 222 and moving their hand to the left.

[0183] While the first to eighth embodiments have been described above, the constituent elements of each embodiment can be combined arbitrarily.

[0184] The inspection system essentially assumes that most game coins are normal. Therefore, when abnormal game coins are detected, this can be announced audibly. For example, by outputting the inspection results via sound and / or lights, the results can be known even if a light is malfunctioning. Furthermore, sound confirmation is easier than visual confirmation. Conversely, when normal game coins are detected, an announcement can be made audibly.

[0185] Furthermore, when game coins become abnormal due to tampering with their appearance, the reading history of the RFID tag 111 can be obtained to trace the state before the tampering, thereby discovering where the cheating occurred.

[0186] For game coins with faulty RFID tag 111 or game coins without RFID tag 111, the game coin can be disassembled for identification.

[0187] It should be noted that in the above embodiment, the RFID antenna is configured to read the intensity of only one game coin, so it will not generate radio waves or magnetic fields at a distance.

[0188] Furthermore, although counterfeit game currency cannot be exchanged, any game currency found to have a faulty RFID tag 111, lacking an RFID tag 111, or being abnormal must be reported to a higher-level person (manager, etc.). In the case of a faulty RFID tag 111 or no RFID tag, the RFID should be identified based on other IDs, and the identified RFID should be deactivated or registered on a blacklist.
