Description

[Technical field]

[0001] The present invention relates to an inspection system for gaming currency having an embedded RFID tag. [Background technology]

[0002] Conventionally, RFID-embedded gaming currency with an RFID tag built in has been known. By storing information on the amount of the gaming currency, identification information, etc. in the RFID tag, it becomes possible to detect illegal gaming currency, manage the inventory of gaming currency, and perform patron rating, etc. RFID technology is advantageous in that it can simultaneously read multiple RFID tags using an RFID reader, allowing multiple gaming currencies to be handled at once. For example, by simultaneously reading the RFID tags of multiple gaming currencies stored in a chip tray with an RFID reader, it is possible to obtain information such as the number of gaming currencies stored in the chip tray and the total amount.

[0003] On the other hand, when the RFID tags of multiple game currencies are read using RFID technology, there is a problem that it is not possible to find illegal game currencies or game currencies with broken RFID tags. For example, if there is one game currencies with a broken RFID tag or no RFID tag among a large number of game currencies (e.g., 1000) that are difficult to count, and the RFID reader reads 999 RFID tags as a result, unless one knows that there are 1000 such game currencies, one cannot know that there is one game currencies whose RFID tag has not been read, even if one knows that 999 RFID tags have been read.

[0004] In addition, even if it is found that a fraudulent coin or a coin with a defective RFID tag is mixed in with a plurality of coins, it is not easy to identify which coin among the plurality of coins has the problem. For example, even if it is found that there is one coin with a problem among 1,000 coins, it is necessary to inspect each coin one by one in order to find the coin with the problem, which requires time and effort.

[0005] Furthermore, there may be cases where the appearance of gaming currency is altered to make it more valuable without altering the RFID tag, or where the RFID tag is removed from one gaming currency and replaced with the RFID tag of another gaming currency, or where the RFID tag removed from a genuine gaming currency is used to manufacture counterfeit gaming currency. In such cases, there is no problem with the information stored in the RFID tag, so it is not possible to recognize such gaming currency as problematic (appearance-altered) gaming currency by simply reading the RFID tag.

[0034] Several embodiments of the present invention will be described below, but the present invention is not limited to the following embodiments, and the technical elements, functions, etc. of the several embodiments can be combined as desired. In addition, the following description will be given using circular chips as an example of gaming currency. For this reason, gaming currency is also called chips.

[0035] (First embodiment) The inspection system of this embodiment is a system that inspects gaming currency received from players when exchanging money in a cage or on a table, or gaming currency received by collecting it from players who have lost a game. The inspection system of this embodiment can also inspect gaming currency held by the casino in a chip tray in a cage or on a table at any time. The inspection system of this embodiment has a placement table on which gaming currency can be placed one by one, and a chip reader is provided on the placement table. Furthermore, gaming currency can be placed on the placement table in groups of five per type.

[0036] 1 is a diagram showing the configuration of an inspection system according to a first embodiment of the present invention. The inspection system 101 is a system for inspecting game currency, and includes a mounting table 10 having a mounting surface 120, a display device 20 for displaying the results of the inspection, a control device 30 for performing calculations for the inspection, and a storage device 40 for storing information on the game currency.

[0037] The upper surface of the mounting table 10 is a mounting surface 120, and the mounting surface 120 is partitioned into a plurality of chip placement areas for placing a plurality of gaming coins to be inspected one by one. In the example of FIG. 1, the mounting surface 120 has 25 chip placement areas arranged in 5 rows and 5 columns. Each chip placement area accepts one chip. These chip placement areas may be partitioned by printing lines on the mounting surface 120, or adjacent chip placement areas may be separated by a wall with a height of about several millimeters. Alternatively, each chip placement area may have a recess for accepting gaming coins.

[0038] FIG. 2 is a diagram showing the configuration of gaming currency and a database. Numbers indicating the type (amount) of the gaming currency 110 are printed on the front and back of the gaming currency. Identification information (e.g., an identification number) unique to the gaming currency 110 is also printed on the front and back of the gaming currency. This identification information may be printed with ink that cannot be observed under natural light, such as ultraviolet-sensitive ink or infrared-absorbing ink. In this case, the identification information may be visualized by irradiating the gaming currency with ultraviolet or infrared light using an ultraviolet or infrared light.

[0039] The gaming currency 110 has a built-in RFID tag 111. The RFID tag 111 stores type (amount) information and identification information of the gaming currency. The RFID tag 111 may further store other information such as information on the casino where the gaming currency is used, manufacturing information, and owner history information.

[0040] The storage device 40 stores information such as type (amount) information, identification information, activation status, and read history for each gaming currency. The activation status is validated in the storage device 40 when the gaming currency is brought into a casino and made available for use there, and is invalidated (deactivated) in the storage device 40 when the gaming currency is no longer used in the casino due to malfunction, deterioration, suspicion of fraud, theft, or the like. The read history stores the installation location of the RFID reader that read the chip in chronological order. In other words, the read history is the movement history of the gaming currency within the casino, and is information that associates the gaming currency with a player or dealer.

[0041] The storage devices 40 are periodically updated. If the storage devices 40 or the inspection system 101 that includes them are connected to a communications network, update data may be sent to each storage device 40 via the communications network.

[0042] Returning to Fig. 1, the placement table 10 has an object detection sensor 11 installed in each of the multiple chip placement areas on the placement surface 120 to detect the presence or absence of gaming currency placed thereon. Each object detection sensor 11 is made up of a pair of a laser irradiator and a laser receiver. When an object (gaming currency) is present in the chip placement area, it outputs an ON signal.

[0043] Further, an RFID reading system is provided in each of the chip arrangement areas on the placement surface 120 of the placement table 10, which reads the RFID tags 111 of the gaming currency 110 placed thereon and acquires type information and identification information for each chip arrangement area. The RFID reading system includes an antenna for reading information from the RFID tag and an RFID reader for controlling the antenna.

[0044] 3 is a diagram showing an example of antennas provided on the mounting table of this embodiment and the intensity distribution of their radio waves or magnetic fields. In this example, a leading antenna 121 and a jamming antenna 12 are provided for each chip arrangement area. The leading antenna 121 generates radio waves or a magnetic field to supply power to the RFID tag 111 and read information from the RFID tag 111.

[0045] The jamming antenna 12 generates radio waves or magnetic fields induced by radio waves or magnetic fields from the leading antennas 121 in the surrounding chip arrangement areas, and shapes the radio waves or magnetic fields of the leading antennas 121 in the surrounding chip arrangement areas. Due to the action of this jamming antenna 12, as shown in the lower part of Fig. 3, the radio waves or magnetic fields formed by the leading antennas 121 in each chip arrangement area have a predetermined strength only within the chip arrangement area and become weak outside the chip arrangement area, so that the leading antennas 121 are prevented from reading the RFID tags 111 of the gaming currency 110 outside the chip arrangement area.

[0046] By combining the reading antenna 121 and the jamming antenna 12 in this manner, the gaming currency 110 placed in each chip placement area cannot be read by the reading antenna 121 wired to other chip placement areas, and overall, it becomes possible to read the RFID tag 111 differently for each chip placement area.

[0047] The positive and negative poles of the reading antenna 121 are connected to an RFID reader, and a current is passed from the RFID reader. The jamming antenna 12 includes a switch 123. When the switch 123 is closed, a closed loop is formed, and when the switch 123 is opened, the closed loop is opened. The RFID reader controls the opening and closing of the switch of each jamming antenna 12.

[0048] The RFID reader sequentially reads RFID tags from a plurality of chip arrangement areas in a time-division manner by activating the reading antenna 121 of each chip arrangement area one by one. In synchronization with switching of the chip arrangement area to be read, the RFID reader closes the switch of the jamming antenna 12 of the chip arrangement areas surrounding the chip arrangement area to be read, thereby turning on the jamming action. This makes it possible to prevent the reading antenna 121 of the chip arrangement area to be read from accidentally reading the RFID tags of the surrounding chip arrangement areas.

[0049] 4 is a diagram showing another example of an antenna provided on the mounting table of the present embodiment. In this example, elongated leading antennas 124, 125 are provided in each row and each column of the chip arrangement area arranged in a two-dimensional matrix. Although not shown, jamming antennas may be provided corresponding to each leading antenna 124, 125, as in FIG. 3.

[0050] In this example, the number of reading antennas 124, 125 can be reduced compared to the case where a reading antenna 121 is arranged for each chip arrangement area as in the example of Fig. 3. The RFID reader uses the multiple reading antennas 124, 125 in sequence to read the RFID tags in a row or column.

[0051] For example, the RFID tag 111 of the gaming currency 110 in the chip arrangement area in the first row of the mounting table 10 can be read by the reading antenna 124 in the first row. Also, the RFID tag 111 of the gaming currency 110 in the chip arrangement area in the first column of the mounting table 10 can be read by the reading antenna 125 in the first column. The RFID tag read in the first row and also in the first column is the RFID tag 111 of the gaming currency 110 arranged in the chip arrangement area in the first row and first column of the chip arrangement areas arranged in a two-dimensional matrix.

[0052] In this way, the RFID reader can read multiple rows one by one and multiple columns one by one, and by referring to the read data, identify the RFID tags 111 of the gaming currency 110 placed in each chip placement area.

[0053] Returning to Fig. 1, the control device 30 determines the state of the gaming currency 110 for each chip arrangement area based on type information obtained by the RFID reading system and the outputs of the multiple object detection sensors 11. To this end, the control device 30 obtains reading results for each chip arrangement area from the RFID reading system, and also obtains detection results from each of the multiple object detection sensors 11. As a result, the control device 30 obtains information stored in the RFID tag 111 and information on the presence or absence of gaming currency for each chip arrangement area.

[0054] 5 is a table showing examples of types of game currency states determined by the control device. The states determined by the control device 30 can be roughly divided into five types: normal, caution, counterfeit, malfunction, and no chip.

[0055] First, the control device 30 determines that the RFID tag 111 of the gaming currency 110 in the chip placement area where the gaming currency is detected by the object detection sensor 11 but the RFID tag 111 cannot be read normally by the RFID reading system is broken or does not have an RFID tag 111 built in.

[0056] More specifically, first, when no gaming currency is detected by the object detection sensor, the control device 30 determines that there are no chips in the chip placement area.

[0057] Furthermore, if the control device 30 is able to read some information from the RFID tag 111 but is unable to decipher that information (for example, if it is able to obtain identification information but not other information), it determines that the data stored in the RFID tag 111 is corrupted, and if it is unable to read any information from the RFID tag 111, it determines that the RFID tag 111 is completely broken or that the RFID tag 111 is not built in.

[0058] Furthermore, when the identification information read by the RFID reading system is not stored in the storage device 40, the control device 30 determines that the gaming currency is counterfeit. In this case, it is suspected that the RFID tag 111 embedded in the gaming currency 110 is not genuine.

[0059] The control device 30 judges that a gaming currency whose identification information read by the RFID reading system is different from the type information of the gaming currency adjacent thereto in the column direction is counterfeit. Since there is no gaming currency adjacent thereto in the column direction for the gaming currency at both ends of each column, the control device 30 judges that the gaming currency at the end is counterfeit if the identification information read by the RFID reading system is different from the identification information of the gaming currency adjacent thereto in the column direction and the identification information of the gaming currency adjacent thereto is the same as the identification information of the gaming currency adjacent thereto.

[0060] In addition, the control device 30 determines that a gaming currency 110 is counterfeit when the identification information read by the RFID reading system does not have a predetermined relationship with the type information of other gaming currency 110 adjacent in the column direction (for example, when comparing a row with the row above it, the amounts in the rows above and below are the same, or the amount in the lower row is larger than the amount in the upper row).

[0061] In this embodiment, when placing game coins in each chip arrangement area of ​​the placement table 10, there is a rule that the same type of game coins are placed in the same row, and game coins with smaller amounts are placed in the upper rows. Therefore, as described above, when the types of game coins adjacent to each other in the same row are different, and when the amount of game coins in the lower row is smaller than the amount of game coins in the upper row, or when 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 genuine, but the appearance of the genuine game coin 110 has been tampered with, or the RFID tag 111 of the genuine game coin 110 has been transplanted to another genuine game coin 110.

[0062] The control device 30 determines that the reading of the RFID tag 111 is unstable for the gaming currency 110 in the chip arrangement area where the reading of the RFID tag 111 is unstable. To make this determination, the RFID reading system is capable of changing the strength of the radio wave or magnetic field for reading the RFID tag 111 for each chip arrangement area. The control device 30 determines that the reading of the RFID tag 111 is unstable for the gaming currency in the chip arrangement area where the reading can be performed when the strength of the radio wave or magnetic field is increased and the reading cannot be performed when the strength of the radio wave or magnetic field is decreased.

[0063] Information on unstable, broken, suspicious chips, and abnormal gaming currency is stored in a database and shared. For example, when a chip is determined to be unstable when read on a chip tray (a place other than the mounting table 10), it is stored in the database, and when it is read on the mounting table 10, it is possible to wait for it to be determined to be an unstable chip based on the information in the database. If information on unstable, broken, suspicious, and abnormal chips is stored in a blacklist in the database, an alert can be issued if the chip matches the information on the blacklist when it is read.

[0064] The control device 30 determines in the memory device 40 that the gaming currency in the chip placement area where the activation status associated with the identification information read by the RFID reading system is invalid is in an invalid state.

[0065] The control device 30 determines that gaming currency that is free of any of the defined problems is in a normal state.

[0066] Returning to Fig. 1, the display device 20 is composed of a display panel having pixels arranged in a matrix. The display screen displays an area-by-area display region 21 showing the result of state judgment for each chip arrangement area, and a total display region 22 showing the total value of the judgment results.

[0067] 6 is a diagram showing an example of use of inspection system 101 according to the first embodiment of the present invention. In this example, five $10 chips are placed on the first row, three $50 chips are placed left justified on the second row, four $100 chips are placed left justified on the third row, three $1000 chips are placed left justified on the fourth row, and five $1000 chips are placed left justified on the fifth row.

[0068] As shown in Fig. 6, in this embodiment, when placing gaming coins one by one in each chip placement area of ​​the placement table 10, the gaming coins are placed so that the same type (amount) in the same row is the same, and the amounts become larger (or equal) in the lower rows. The inspector places the gaming coins in each chip placement area while checking the appearance of the gaming coins, i.e., the amounts written on the front and back of the gaming coins.

[0069] In this example, the $10 chip located in area number 3 is gaming currency that does not have an RFID tag 111 built in, the $50 chip located in area number 6 is gaming currency whose RFID tag 111 is malfunctioning, the $1000 chip in area number 17 is gaming currency whose identification information stored in its RFID tag 111 is not stored in memory device 40, and the $1000 chip in area number 24 has an RFID tag that is that of a $10 gaming currency but has the appearance of a $1000 chip, and is gaming currency whose appearance has been tampered with.

[0070] For area numbers 3 and 6, gaming currency is detected by the object detection sensor 11, but the RFID reading system is unable to read the information, so it is determined that either the RFID tag 111 is faulty or the gaming currency does not contain an RFID tag 111.

[0071] A display indicating such an error is displayed in the area of ​​the corresponding area number in the area display region 21. Specifically, the area is displayed in red, and a message is displayed indicating that the RFID tag 111 is broken or that the gaming currency does not include the RFID tag 111.

[0072] For area number 17, it is determined that gaming currency has been detected by the object detection sensor 11 and the RFID tag 111 has been read by the RFID reading system, but the identification information has not been stored in the storage device 40. In this case, an indication of such an error is displayed in the area of ​​the corresponding area number in the area display region 21. Specifically, the area is displayed in orange, and text is displayed to the effect that the RFID tag 111 or the identification information is not registered. In this case, even if the amount information of the gaming currency can be identified, the amount is not displayed.

[0073] For area number 24, gaming currency is detected by the object detection sensor 11, and identification information read from the RFID tag 111 is stored in the storage device 40, but it is determined that the amount information associated with the identification information in the storage device 40 does not match the amount of gaming currency on either side. Specifically, the amount of gaming currency on either side (area number 23 and area number 25) is 1000 dollars, while the amount information associated with the identification information read from the RFID tag 111 of area number 24 is 10 dollars.

[0074] This situation may occur, for example, when the appearance of a genuine $10 chip is tampered with to make it look like a $1000 chip, or when a counterfeit $1000 chip is made using the RFID tag 111 of a genuine $10 chip. The dealer can visually check the difference between the information based on the RFID tag 111 and the appearance to determine whether the dealer has placed the chip incorrectly, and if so, can replace it.

[0075] In this case, a display indicating such an error is displayed in the area of ​​the corresponding area number in the area display region 21. Specifically, the area is displayed in orange, and a message is displayed in text indicating that the gaming currency is counterfeit. In this case, the amount information associated with the identification information read from the RFID tag 111 is displayed in the area of ​​the corresponding area number in the area display region 21.

[0076] In this embodiment, the identification information read from the RFID tag 111 is used to refer to the memory device 40 to identify the amount information associated with the identification information and compare it with the adjacent information on either side, but instead of or in addition to this, it may be determined whether the amount information read from the gaming currency is different from the information on either side.

[0077] The total results of reading and judging the multiple chip arrangement areas are displayed in tally display area 22. Fig. 7 is a diagram showing a display example of the tally display area in the example of Fig. 6. In the example of Figs. 6 and 7, the gaming currencies judged to be normal in tally display area 22 are four $10 chips, two $50 chips, four $100 chips, and six $1000 chips, so the subtotals for each amount ($40 for $10 chips, $100 for $50 chips, $400 for $100 chips, and $6000 for $1000 chips) and a grand total of $6,540 are shown.

[0078] In addition, for the gaming currency 110 that is illegal or has an abnormality, the details of the illegality or abnormality and the number of the gaming currency are displayed. In the examples of Figures 6 and 7, it is shown that the number of gaming currency determined to have a malfunction of the RFID tag 111 or to have no RFID tag 111 is two, one gaming currency determined to be unregistered, and one gaming currency determined to be counterfeit.

[0079] Fig. 8 is a diagram showing another example of use of the inspection system 101 according to the first embodiment of the present invention. In the example of Fig. 8, only one 100-dollar chip is placed. In such a case, the 100-dollar chip cannot be compared with the amount of other chips in the same row. However, for area number 11, a 50-dollar chip is placed in the row (row 2) above the row (row 3) that includes that area, and a 1000-dollar chip is placed in the row (row 4) below the row (row 3) that includes that area.

[0080] The control device 30 judges whether the amount of the gaming currency in area number 11 satisfies the above-mentioned predetermined relationship in relation to the amounts read in the upper and lower rows for the area with area number 11. In the example of FIG. 8, in area number 11, the amount associated with the identification information read by the RFID reading system in the storage device 40 is 10 dollars. In this case, the amount in the lower row (fourth row) is smaller, so the predetermined relationship is satisfied, but the amount in the upper row (second row) is smaller, so the predetermined relationship is not satisfied. Therefore, the control device 30 judges that there is something abnormal with the amount of 10 dollars specified for area number 11, and that the gaming currency is counterfeit.

[0081] Fig. 9 is a diagram showing a display example of the tally display area in the example of Fig. 8. In the examples of Fig. 8 and Fig. 9, the gaming currency determined to be normal is five $10 chips, three $50 chips, zero $100 chips, and seven $1000 chips, so the tally display area 22 shows the subtotals for each amount ($50 for $10 chips, $150 for $50 chips, $0 for $100 chips, and $7000 for $1000 chips) and the grand total of $7200.

[0082] In addition, for the gaming currency 110 that is illegal or has an abnormality, the details of the illegality or abnormality and the number of coins are displayed. In the examples of Figures 8 and 9, it is shown that one gaming currency has been determined to be counterfeit.

[0083] In the above embodiment, a rule is established that the same amount of gaming coins 110 are placed in each row, with smaller amounts of gaming coins 110 being placed in the upper rows, and the dealer places the gaming coins 110 one by one in the chip placement area so that the dealer visually follows the rule. However, instead of this, a rule may be established that the same amount of gaming coins 110 are placed in each row, with larger amounts of gaming coins 110 being placed in the upper rows, or a rule may be established that the same amount of gaming coins 110 are placed in each column, with smaller amounts of gaming coins 110 being placed in the left column, or a rule may be established that the same amount of gaming coins 110 are placed in each column, with smaller amounts of gaming coins 110 being placed in the right column.

[0084] In addition, in the above embodiment, a rule was established that the same amount of gaming coins 110 were placed in each row, and the upper the row, the smaller the amount of gaming coins 110 placed, and the control device 30 determined that gaming coins 110 of a different amount from those on either side were counterfeit. However, instead, when the same row contains gaming coins 110 of multiple amounts, the majority amount may be determined to be correct, and the minority amount may be determined to be counterfeit.

[0085] In this case, the control device 30 first judges whether or not multiple amounts of gaming currency 110 are included in the same row. Then, when multiple amounts of gaming currency 110 are included, it judges which amount of gaming currency 110 is counterfeit by judging which amount is larger and which amount is smaller. Also, even when a rule is set that the same amount of gaming currency 110 is placed on the entire placement table 10, when multiple amounts of gaming currency 110 are included, the majority amount may be determined as correct and the minority amount may be determined as counterfeit.

[0086] Furthermore, a rule may be set that the same amount of gaming currency 110 is placed in the same row, and the size relationship of the gaming currency 110 placed in each row is arbitrary. In this case, the control device 30 may use the amount of the gaming currency 110 in the leftmost column (first column) of each row as a reference, and determine whether the amount of the gaming currency 110 in the second column and thereafter is the same as the amount of the gaming currency 100 in the first column.

[0087] 10 is a diagram showing an inspection system according to a modified example of the first embodiment of the present invention. In this example, the amount of chips to be placed in each of the chip placement areas of the placement table 10 is assigned in advance. Each chip placement area on the placement surface 120 of the placement table 10 is printed with a number indicating the amount of gaming currency to be placed there. The dealer or other casino staff place gaming currency one by one in each chip placement area according to this number.

[0088] If the amount information associated with the identification information read from each chip placement area in the memory device 40 differs from the amount assigned to that chip placement area, the control device 30 determines that the gaming currency in that chip placement area is counterfeit.

[0089] 11 is a diagram showing an example of use of the inspection system according to the modified example of the first embodiment of the present invention. In this example, the amount assigned to area number 24 is 1000 dollars, but in the storage device 40, an amount of 10 dollars is associated with the identification information read by the RFID reading system. In other words, since the amount identified based on the RFID tag 111 is different from the amount assigned to the chip arrangement area, the control device 30 determines that the gaming currency is counterfeit.

[0090] Since the gaming currency 110 appears to be $1000, the dealer and other casino staff place it in the chip placement area with area number 24. Therefore, the amount of the gaming currency 110 determined from its appearance does not match the amount determined from the RFID tag 111, and the gaming currency 110 is determined to be counterfeit.

[0091] As described above, according to the inspection system of the first embodiment of the present invention and its modified example, a plurality of chip arrangement areas are provided on the placement table 10, and gaming currency is placed one by one in each chip arrangement area for inspection. A reading antenna 121 and an object inspection sensor 11 for reading the RFID tag 111 are provided in each chip arrangement area. The reading antenna 121 reads the RFID tag 111 of the gaming currency 110 in each chip arrangement area, and the object inspection sensor 11 detects the presence or absence of the gaming currency 110 in each chip arrangement area.

[0092] With this configuration, in a chip placement area where the object detection sensor 11 detects (game currency is placed therein) but the RFID tag 111 cannot be read, it can be determined that the RFID tag 111 of that game currency is faulty or that the RFID tag 111 is not built into that game currency.

[0093] In the first embodiment, the casino is provided with a storage device 40 that stores identification information of gaming currency used in the casino, and the control device 30 judges whether or not the identification information read from each chip arrangement area by the RFID reading system is stored in the storage device 40. If the read identification information is not stored in the control device 30, the control device 30 judges that the gaming currency 110 is unregistered.

[0094] Furthermore, in the first embodiment, predetermined rules are established for the placement of the amount of gaming coins on the placement surface 120, and the dealer or casino staff recognizes the amount of the gaming coin from its appearance and places the gaming coin based on the rules, or the amount of gaming coins to be placed in each chip placement area is assigned in advance, and the dealer or casino staff recognizes the amount of the gaming coin from its appearance and places gaming coins corresponding to the assigned amount in each chip placement area.

[0095] The control device 30 refers to the storage device 40 to identify the amount associated with the identification information read by the RFID reading system, and judges whether the identified amount corresponds to the above-mentioned rule or assigned amount. This makes it possible to determine that gaming currency whose amount indicated by its appearance differs from the amount identified by the RFID tag 111 is counterfeit.

[0096] In the above embodiment, the RFID reading system reads the identification information from the RFID tag 111 of the gaming currency 110, and the control device 30 refers to the storage device 40 to identify the amount associated with the identification information, thereby identifying the amount based on the RFID tag 111 of the gaming currency 110. However, in addition to this, or instead of this, the RFID reading system may read amount information from the RFID tag 111, and the control device 30 may identify the amount of the gaming currency 110 based on the amount information read by the RFID reading system. In this case, the storage device 40 may be omitted. Alternatively, when the amount of the gaming currency 110 is identified by the amount stored in the storage device 40, the amount information stored in the RFID tag 111 may be omitted.

[0097] In addition, the control device 30 may determine whether the amount information stored in the RFID tag 111 corresponds to (indicates the same amount) the amount information associated with the identification information read from the RFID tag 111 in the memory device 40, and thereby determine whether the gaming currency 110 or the RFID tag 111 is counterfeit or has been tampered with.

[0098] The determination of each state shown in Fig. 5 will be further explained. The RFID reading system can change the strength of the radio waves or magnetic field (hereinafter referred to as "antenna strength") emitted from the reading antenna 121. The RFID reading system changes the antenna strength and reads the gaming currency 110 placed in each chip arrangement area of ​​the placement table 10 multiple times. For example, the RFID reading system reads with two levels of antenna strength, strong and weak.

[0099] The control device 30 can read the RFID tag 111 when the antenna strength is strong, but if the RFID tag 111 cannot be read when the antenna strength is weak, it determines that the gaming currency 110 in that chip arrangement area is unstable.

[0100] Furthermore, as described above, the activation status is stored in the storage device 40. When the activation status of the identification information read from the RFID tag 111 in the storage device 40 is not valid (for example, not yet activated or deactivated), the control device 30 determines that the gaming currency 110 is invalid.

[0101] Casinos monitor for fraudulent gaming currency and fraudulent activities at every stage, and although they cannot confirm that a gaming currency is fraudulent, they may be deemed suspicious. In addition, caution should be exercised when using gaming currency involved in fraudulent activities, and such gaming currency may be made unusable even if it is not confirmed that it is counterfeit.

[0102] For such suspicious gaming currency, unusable information can be stored in association with the identification information of the gaming currency in the storage device 40. When the identification information is read by the RFID reading system in the inspection system 101 and the identification information is set to unusable in the storage device 40, the control device 30 determines that the gaming currency is in an unusable state.

[0103] Furthermore, in the above embodiment, the control device 30 determines that the RFID tag 111 has failed or is missing when information cannot be read from the gaming currency 110. However, if some information can be read from the RFID tag 111 and it can be determined that the RFID tag 111 is present but no valid information is stored in the RFID tag, for example, if the TID (Tag ID) area of ​​the RFID tag 111 can be read but the data in the EPC (Electronic Product Code) area or user area is corrupted, it may be determined that the RFID tag 111 has failed (or is missing).

[0104] (Second embodiment) 12 is a diagram showing a configuration of a system according to a second embodiment of the present invention. This system comprises a plurality of inspection systems 102 and a chip management system 200. The plurality of inspection systems 102 and the chip management system 200 are communicatively connected via a communication network 300.

[0105] The chip management system 200 is installed in a casino facility, and an intranet may be used as the communication network 300, or the chip management system 200 may be connected to a plurality of inspection systems 102 in the casino facility via the Internet 300. In the chip management system 200, information on the amount of each gaming currency, reading history, information on activation and deactivation, information on unstable chips, information on unusable chips, and the like are updated in association with the identification information of each gaming currency, and 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 memory device 40, and the control device 30 of each inspection system 101 refers to the memory device 40 in the same inspection system 101 to determine whether the identification information is registered, etc., but in the present embodiment, the inspection system 102 does not have a memory device 40, and the control device 30 determines whether the identification information read from the RFID tag 111 of the gaming currency 110 by the RFID reading system by inquiring of the chip management system 200 via the communication network 300, thereby determining whether the identification information is registered, etc.

[0106] Each inspection system 102 may include a storage device 40. In this case, each inspection system 102 does not need to connect to the chip management system 200 via the communication network 300 every time an inspection is performed, and the control device 30 can access the storage device 40 to perform the inspection. In this case, the storage device 40 of each inspection system 102 is periodically updated by the chip management system 200 via the communication network 300.

[0107] 13 is a diagram showing a configuration of an inspection system 102 according to a second embodiment of the present invention. In the description of the inspection system 102 according to this embodiment, elements having similar functions to those of the inspection system 101 according to the first embodiment are given the same reference numbers and descriptions thereof will be omitted as appropriate.

[0108] The inspection system 102 includes a mounting table 10, a display device 20, a control device 30, and an image capturing device 50. Although not shown in Fig. 13, the inspection system 102 also includes an RFID reading system similar to that of the inspection system 101. The control device 30 of this embodiment has a communication function and communicates with the chip management system 200. In this embodiment, the mounting table 10 is provided with a total of 16 chip arrangement areas arranged in 4 rows and 4 columns.

[0109] In the inspection system 102, each chip arrangement area is not provided with an object inspection sensor 11, but instead is provided with an imaging device 50 that captures an image of the mounting table 10. The imaging device 50 is a camera system that includes an optical system such as a lens, an imaging element, an image processing device, and the like.

[0110] The photographing device 50 photographs the gaming currency 110 placed on each chip arrangement area of ​​the placement table 10 from above the placement table 10 to generate a photographed image. The camera 20 generates a full-color image. The number of photographing devices 50 is not limited to one, and two or more may be provided. In addition, when information such as identification information is written on the gaming currency 110 with invisible ink such as ultraviolet-sensitive ink or infrared-absorbing ink, an ultraviolet light or infrared light is provided in association with the photographing device 50 to visualize such invisible ink.

[0111] The control device 30 has an image recognition function that recognizes chips in each chip arrangement area and determines the type of chips by performing image recognition on the captured image. 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. These machine learning techniques are designed and learned to be able to recognize the gaming currency 110 at any rotation angle. In addition, in the image recognition, a difference image may be generated from an image of the placement surface 120 in a state where the gaming currency 110 is not placed and an image of the placement surface 120 in a state where the gaming currency 110 is placed, so that the gaming currency 110 is extracted and recognized. In addition, the difference image may be used to detect only the presence or absence of the gaming currency 110, and the gaming currency 110 may be inspected in the same manner as in the first embodiment.

[0112] The control device 30 may identify the amount of the gaming currency by recognizing the numbers written on the gaming currency 110 through image recognition. Alternatively, the control device 30 may extract features from the entire image of the gaming currency through self-learning and recognize the amount without specifying features for identification. In addition to the numbers representing the amount, the gaming currency 110 has different colors and patterns for each amount, so these colors and patterns can also be features for distinguishing the amount.

[0113] As described above, when the identification information is written in visible or invisible ink on the gaming currency 110, the control device 30 also reads the identification information based on the captured image. In this case, recognition may be performed using a neural network such as deep learning.

[0114] The display device 20 includes an area lamp section 23 and a liquid crystal display section 24. The area lamp section 23 includes a plurality of lamps arranged in a manner corresponding to the chip arrangement areas of the mounting surface 120 of the mounting table 10. The lamps include LED light-emitting elements of the three primary colors and can emit any color.

[0115] In this embodiment, the state of the gaming currency determined by the control device 30 is expressed by the lighting color of the lamp in the area lamp section 23. In this embodiment, the control device 30 determines that each chip placement area is in one of the following states: "normal," "caution," "counterfeit," "malfunction," or "no chip," and lights up the lamp green (normal), yellow (caution), orange (counterfeit), or red (malfunction), or does not light up the lamp if there are no chips.

[0116] The chip management system 200 functions as a database server that stores data similar to the data stored in the storage device 40 of the first embodiment. That is, the chip management system 200 stores the identification information, amount information, activation status, reading history, unusable flag, etc. of all gaming currency 110 used in the casino, and can specify the amount information, activation status, etc. associated with the identification information using the identification information as a key.

[0117] If the gaming currency 110 is unstable, invalid, or unusable, the control device 30 judges it to be a "caution" and turns on the lamp of the area number of the gaming currency in yellow. The blinking pattern of the yellow may be changed depending on whether the gaming currency is unstable, invalid, or unusable. For example, the blinking pattern may be different for invalid and unusable, with the lamp being lit for unstable and the lamp being blinking for invalid and unusable.

[0118] When the reading of the RFID tag 111 of the gaming currency 110 is unstable, the control device 30 may store information to that effect in the chip management system 200 in association with the identification information. When the control device 30 subsequently acquires identification information from the RFID reading system for the gaming currency having unstable information stored in the chip management system 200 in this way, the control device 30 can grasp that the reading of the RFID tag 111 of the gaming currency 110 is unstable by inquiring of the chip management system 200 using the identification information as a key.

[0119] Furthermore, if the amount recognized from the captured image by the image recognition function does not correspond to the amount obtained by referring to the chip management system 200 using the identification information read from the RFID tag 111 by the RFID reading system as a key, the control device 30 determines that the appearance of the gaming currency has been tampered with. Furthermore, if the identification information read from the RFID tag 111 by the RFID reading system is not stored in the chip management system 200, the control device 30 determines that the identification information of the RFID tag 111 of the gaming currency is unregistered.

[0120] When the control device 30 determines that the appearance has been tampered with or that the RFID tag 111 is unregistered, it determines that the gaming currency 110 is in a "counterfeit" state and turns on the lamp of the area number of the gaming currency in orange. Note that the blinking pattern of the orange may be changed depending on whether the appearance has been tampered with or the identification information is unregistered. For example, the orange may be turned on to indicate that the appearance has been tampered with and blinked to indicate that the RFID tag is unregistered.

[0121] If, as a result of image recognition of the captured image, the control device 30 does not obtain a reading result of the RFID tag 111 from the RFID reading system for the chip placement area in which gaming currency is recognized, it determines that the RFID tag 111 of the gaming currency 110 in that chip placement area is faulty or that the gaming currency 110 in that chip placement area does not have an RFID tag 111, determines that the status of that gaming currency 110 is "faulty," and lights up the lamp of the area number of that gaming currency 110 in red.

[0122] As a result of image recognition of the photographed image, the control device 30 determines that there is no chip in a chip placement area in which no gaming currency is recognized as "no chip," and does not light up the lamp of the area number of that chip placement area.

[0123] As described above, the control device 30 has a lamp control function for controlling the lighting of each lamp of the area lamp display unit 23 in accordance with the result of the determination.

[0124] The liquid crystal display unit 24 displays the total inspection results of each of the chip arrangement areas. Specifically, the liquid crystal display unit 24 displays the number of gaming coins judged to be "normal" and the total number of gaming coins judged to be "caution", "counterfeit", or "broken", that is, the number of illegal or abnormal gaming coins.

[0125] 14 is a diagram showing an example of 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 gaming currency 110 in area number 3 is unstable and in a "caution" state, and turns on the lamp in area number 3 of the area lamp unit 23 in yellow.

[0126] In addition, the control device 30 recognizes from the captured image that there is a $100 chip in area number 8, and based on the result from the RFID reading system that the RFID tag 111 cannot be read from the gaming currency 110 in area number 8, determines that the RFID tag 111 is in a "broken" state and lights up the lamp for area number 8 in the area lamp unit 23 in red.

[0127] Furthermore, the control device 30 acquires the identification information read from the RFID reading system for area number 9, queries the chip management system 200 using this identification information as a key, and acquires information that the amount is 10 dollars as information associated with the identification information. On the other hand, the control device 30 recognizes that the gaming currency 110 for area number 9 is a 100 dollar chip from the photographed image. Since the amount information (10 dollars) stored in the chip management system 200 differs from the amount information (100 dollars) recognized from the photographed image, the control device 30 determines that the gaming currency 110 is a "counterfeit" whose appearance has been tampered with, and lights up the lamp for area number 9 in the area lamp unit 23 in orange.

[0128] Furthermore, the control device 30 acquires the identification information read from the RFID reading system for area number 11, and uses this identification information as a key to make an inquiry to the chip management system 200. When the control device 30 receives a result from the chip management system 200 indicating that the identification information is unregistered, it determines that the gaming currency 110 is a "counterfeit" that uses an unregistered RFID tag, and lights up the lamp for area number 11 in the area lamp unit 23 in orange.

[0129] Furthermore, for area numbers 1, 2, 4-7, 10, and 12-14, the control device 30 performs image recognition on the photographed image, and as a result recognizes the gaming currency 110 and there are no problems as described above, determines that these gaming currency 110 are "normal" and turns on the lamps of area numbers 1, 2, 4-6, 10, and 12-14 in green on the area lamp unit 23. Note that for area numbers 15 and 16, the control device 30 does not turn on the lamps of area numbers 15 and 16 in the area lamp unit 23 as a result of performing image recognition on the photographed image, and as a result recognizes the gaming currency 110.

[0130] Fig. 15 is a diagram showing a modified example of the display of the liquid crystal display unit in the second embodiment of the present invention. As shown in Fig. 15, the liquid crystal display unit 24 may display the number of normal gaming currency 110 by denomination and the subtotal, and the total amount of normal gaming currency 110. In addition, for illegal or abnormal gaming currency 110, the area number and the details of the illegal or abnormal gaming currency 110 may be displayed.

[0131] In the examples of Figures 14 and 15, as described above, area number 3 is determined to be unstable, area number 8 is determined to have an RFID malfunction or no RFID, area number 9 is determined to have had its appearance tampered with, and area number 11 is determined to have an RFID tag 111 that is unregistered, and the respective details are displayed on the LCD display unit 24.

[0132] As described above, according to the inspection system 102 of this embodiment, the image capturing device 50 captures an image of the gaming currency 110 placed on the placement table 10, thereby recognizing the amount of the gaming currency from its appearance. Therefore, unlike the inspection system 101 of the first embodiment, it is not necessary to place the gaming currency 110 according to a predetermined rule or an amount previously assigned to the placement table 10, and any amount of gaming currency 110 can be placed in a plurality of chip placement areas.

[0133] In this embodiment, the control device 30 may make the determination using the identification information written on the surface of the gaming currency 110. For example, the control device 30 may read the identification information written on the surface of the gaming currency 110 from the photographed image and make an inquiry to the chip management system 200. In this case, the RFID reading system may be omitted.

[0134] Alternatively, the identification information recognized from the photographed image may be compared with the identification information recognized by the RFID reading system to determine the type of gaming currency. If the two are different, the control device 30 determines that the appearance of the gaming currency 110 has been tampered with or that an unregistered RFID tag 111 is being used.

[0135] Furthermore, the control device 30 determines the gaming currency to be normal if there are no problems detected by the inspection system 102.

[0136] In this embodiment, the gaming currency 110 stores identification information in the RFID tag 111, and further has identification information by means other than the RFID tag, i.e., by printing with ink. Also, the chip management system 200 stores the reading history of the RFID reading system of each inspection system 102. That is, the chip management system 200 stores when and by which inspection system 102 which identification information was read.

[0137] According to such a configuration, when the control device 30 determines that the RFID tag of a gaming currency is broken or that no RFID tag is built in, it can use identification information possessed by a means other than the RFID tag to acquire the reading history of the gaming currency stored in the chip management system 200. This makes it possible to track to what extent the RFID tag 111 has been correctly read, which can lead to the discovery of fraud.

[0138] If the RFID is broken or there is no RFID tag, the identification information to be deactivated is not known, so the identification information possessed by a means other than the RFID tag can be found and the identification information can be deactivated. For gaming currency that does not have an RFID tag 111 because a normal RFID tag 111 has been removed, there is a risk that the removed RFID tag 111 may be used to counterfeit another gaming currency, so the identification information identified by a means other than the RFID tag is deactivated.

[0139] (Third embodiment) 16 is a diagram showing the configuration of an inspection system according to a third embodiment of the present invention. The inspection system 101 according to the first embodiment described above is a stand-alone type in which the mounting table 10, the display device 20, the control device 30, and the storage device 40 are integrated together and can be used even when not connected to a communication network.

[0140] Moreover, the inspection system 102 of the second embodiment is a network type in which the chip management system 200 corresponding to the memory device 40 is connected to a plurality of inspection systems 102 via a communication network. In the inspection system 103 of the present embodiment, the mounting table 10, the display device 20, the control device 30, and the chip management system 200 corresponding to the memory device 40 are each configured as separate devices.

[0141] 16, the gaming currency 110 in area number 7 appears to be a $50 chip, but the amount based on the reading of the RFID tag 111 by the RFID reading system is $100. In this case, the display device 20 displays that $50 and $100 have been recognized for area number 7.

[0142] As for area number 8, the gaming currency 110 does not have an RFID tag 111, and the amount cannot be identified based on the RFID tag 111, but the photographing device 50 recognizes it as 100 dollars based on its appearance. Therefore, the display device 20 displays a message that the RFID tag 11 could not be read and that the appearance is 100 dollars. That is, in this embodiment, the contents recognized via the photographing device and the contents recognized via the RFID reading system are displayed as they are.

[0143] In this embodiment, the control device 30 may be a personal computer, and the display device 20 may be a PC monitor.

[0144] 17 is a diagram showing a modified example of the inspection system according to the third embodiment of the present invention. In this example, the inspection system 103 includes a mounting table 10 with a built-in RFID reading system, a tablet computer 600, and a chip management system 200. In other words, compared to the third embodiment, the display device 20, the control device 30, and the photographing device 50 are realized by a single device, the tablet computer.

[0145] The tablet computer 600 and (the RFID reading system of) the mounting stand 10 communicate with each other by wire or short-distance wireless communication. The tablet computer 600 is connected to the communication network 300 by a wireless router and communicates with the chip management system 200.

[0146] In this example, all functions of the control device 30, such as image recognition, determination, and display, may be provided to the tablet computer 600 as a single packaged application.

[0147] (Fourth embodiment) 18 is a diagram showing the configuration of an inspection system according to a fourth embodiment of the present invention. In the inspection system 104 of this embodiment, a placement surface 120 is installed at a position close to the dealer position on the table surface of a game table 500. On the placement surface 120, chip placement areas of 4 rows and 5 columns are partitioned by lines. In addition, a display device 20 is embedded in the table surface near the placement 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 chip management system 200 via a communication network 300. The RFID reading system reads the RFID tag 111 of the gaming currency 110 placed in each chip placement area of ​​the placement surface 120. A camera may be installed on the ceiling to recognize the gaming currency.

[0149] The control device 30 queries the chip management system 200 using the identification information read by the RFID reading system from the RFID tag 111 as a key, and obtains the amount information associated with the identification information. Thereafter, in the same manner as in the first embodiment, it may be checked whether the specified amounts are the same for each row and whether the amounts in the upper rows are smaller.

[0150] Alternatively, the control device 30 may determine whether the gaming currency 110 in each chip placement area is normal or not based on whether the amount information read from the RFID tag 111 of the gaming currency 110 by the RFID reading system matches the amount obtained from the chip management system 200.

[0151] In this embodiment, the lines dividing each chip placement area on the placement surface may be illuminated by LED lights from below the table surface when necessary to indicate the chip placement areas.

[0152] In the present embodiment, the chip tray 501 is a tray that stores chips of the dealer, and may be provided with an RFID reading system. The RFID reading system of the chip tray 501 and the RFID reading system of the inspection system 104 may cooperate with each other.

[0153] 19 is a diagram showing a modified example of the inspection system according to the fourth embodiment of the present invention. In this example, five chip placement areas are provided in one row on the table surface of a game table 500. The dealer places gaming currency 110 of the same amount in this row. The chip placement areas may be equipped with monitors or lamps.

[0154] The RFID reading system reads amount information stored in the RFID tag 111 of the gaming currency 110 placed one by one in each of the chip arrangement areas. The control device 30 acquires the read result from the RFID reading system. If there is even one gaming currency 110 with a different amount among the multiple amount information acquired from the RFID reading system, that is, if the amount information of all the gaming currency 110 is not the same, the control device 30 determines that a counterfeit gaming currency 110 is present among the multiple gaming currency 110.

[0155] In addition, even if the RFID tags 111 have not been read for the number of chip placement areas (five in this example), the control device 30 determines that among the multiple gaming currencies 110, there is a gaming currencies 110 whose RFID tags 111 are faulty or which do not have an RFID tag 111.

[0156] The inspection system 104 in this example is equipped with three lamps as the display device 20. The turning on and off of each lamp is controlled by the control device 30. The control device 30 turns on a green normal lamp when the five gaming coins 110 are normal, turns on an orange counterfeit lamp when it determines that there is a counterfeit gaming coin 110, and turns on a red malfunction lamp when it determines that the RFID tag 111 is malfunctioning or that there is a gaming coin 110 that does not have an RFID tag 111.

[0157] According to this example, the area of ​​the table surface of the game table 500 that the inspection system 104 occupies can be kept small, thereby minimizing the influence on other operations by the dealer.

[0158] (Fifth embodiment) Fig. 20 is a diagram showing the configuration of an inspection system according to a fifth embodiment of the present invention. As shown in Fig. 20, in an inspection system 105 according to this embodiment, a display device 20 that shows the judgment result is provided in each chip arrangement area of ​​a mounting table 10. In this embodiment, the display device 20 provided in each chip arrangement area is a lamp that shows the judgment content by its color, but in addition to this, or instead of this, a liquid crystal display panel may be provided in each chip arrangement area.

[0159] The inspection system 105 inspects the gaming currency 110 in the same manner as the inspection system 101 of the first embodiment, and expresses the judgment result of the gaming currency in each chip placement area by the color of the lamp in the corresponding chip placement area.

[0160] (Sixth embodiment) Fig. 21 is a diagram showing the configuration of an inspection system according to the sixth embodiment of the present invention. As shown in Fig. 21, in comparison with the inspection system 101 according to the first embodiment, an inspection system 106 according to the present embodiment has a multiple chip arrangement area 16 provided on a mounting table 10.

[0161] A reading antenna (not shown) is provided in this multiple chip arrangement area 16 for reading the RFID tags 111 of the multiple gaming currencies 110 placed in the multiple chip arrangement area 16. As in the first embodiment, a jamming antenna may be provided corresponding to this reading antenna, or a shield may be provided to prevent this reading antenna from reading the RFID tags 111 of the gaming currencies 110 placed in the adjacent multiple chip arrangement areas.

[0162] When a dealer or other casino staff uses the inspection system 106 of this embodiment, they first stack multiple gaming coins 110 (e.g., five coins in one row) to be placed in the chip placement area in the multiple chip placement area 16 before placing each gaming coin 110 in the chip placement area one by one.

[0163] The reading antenna in the multiple chip arrangement area 16 collectively reads the RFID tags 111 of the multiple game currencies 110 placed in the multiple chip arrangement area 16 , and displays the results on the multiple read result display unit 25 .

[0164] 22 is a diagram showing an example of use of the inspection system according to the sixth embodiment of the present invention. In this example, five 100-dollar chips are placed in the multiple chip arrangement area 16. The multiple reading result display unit 25 displays the results of reading the multiple chip arrangement area 16 by the RFID reading system.

[0165] In this manner, the dealer or other casino staff (hereinafter simply referred to as the "dealer") takes out five gaming currencies 110 and places them in the multiple chip arrangement area 16. At this time, the dealer visually checks the amounts of the five gaming currencies 110. Typically, five gaming currencies 110 of the same amount are placed in the multiple chip arrangement area 16.

[0166] The contents read by the RFID reading system in the multiple chip placement area 16 are displayed on the multiple reading result display unit 25, and the dealer checks them. If the results differ from the results visually confirmed, the dealer places the five gaming coins 110 one by one in the chip placement area for further inspection.

[0167] Since placing gaming coins one by one takes time, multiple gaming coins may be placed together, and the dealer may check the multiple reading result display unit 25 on which information is displayed, and end the inspection if it is confirmed that all gaming coins are normal. In this way, the time required for the inspection can be shortened. If an abnormal gaming coin is confirmed by placing multiple gaming coins, the gaming coins can be placed one by one in the chip placement area, and the abnormal gaming coin can be confirmed.

[0168] In this embodiment, the amount of gaming currency 110 placed in the multiple chip arrangement area 16 is specified, but instead, only the number of coins may be specified. In this case, the dealer visually checks the predetermined number of coins and displays the number of RFID tags 111 read as the reading result on the multiple reading result display unit 25 in the multiple chip arrangement area 16.

[0169] Even with this configuration, it is possible to first check whether the RFID tag 111 is broken or whether there is gaming currency 110 that does not have an RFID tag 111 among the multiple gaming currency 110. If there is gaming currency 110 that has a broken RFID tag 111 or does not have an RFID tag 111, the number of gaming currency 110 placed in the multiple chip arrangement area 16 and the number displayed on the multiple reading result display unit 25 will differ.

[0170] However, at this stage, it is unclear which of the multiple gaming coins 110 has a problem. Therefore, these multiple gaming coins are placed one by one in multiple adjacent chip arrangement areas and inspected one by one.

[0171] The multiple chip arrangement area 16 may be designed to be wide enough to accommodate, for example, five chip cases each containing 20 chips. In this case, five chip cases each containing 20 chips (a total of 100 chips) are placed in the multiple chip arrangement area 16, and the results are displayed on the multiple read result display unit 25. The inspector places multiple chip cases each containing 20 chips in the multiple chip arrangement area 16, and if the read results match the gaming currency visually confirmed (for example, 100 chips in 5 cases of 20 100 dollar chips), the inspection ends there, and if they do not match, the inspector may place those chip cases one by one in the multiple chip arrangement area 16 and perform the inspection. Then, if a problematic chip case can be identified, the inspector may open that chip case, remove the gaming currency 110, and place it one by one in the chip arrangement area of ​​the placement table 10 to perform the inspection.

[0172] Alternatively, the control device 30 may determine whether or not there are a predetermined number (e.g., 100) of gaming currency 110 of the same amount in the multiple chip arrangement area 16, and display only the result of the pass / fail determination on the multiple reading result display unit 25. The control device may also determine only whether the amounts of the multiple gaming currency 110 read in the multiple chip arrangement area 16 are all the same, and display the result of the pass / fail determination on the multiple reading result display unit 25. The multiple chip arrangement area 16 and the multiple reading result display unit 25 may be configured as separate entities from the placement table 10.

[0173] (Seventh embodiment) 23 is a diagram showing the configuration of an inspection system according to a seventh embodiment of the present invention. Compared with the inspection system according to the first embodiment, the inspection system 107 according to this embodiment does not include a storage device 40, and can be used without communicating with the chip management system 200 as in the second embodiment. Moreover, the control device 30 does not perform the above-mentioned inspection or judgment.

[0174] The RFID reading system of the placement table 10 reads amount information from the gaming currency 110 placed in each chip placement area. The control device 30 displays the amount information read by the RFID reading system in the area-by-area display region 21. The control device 30 also totals the amount information read by the RFID reading system from the RFID tags 111 of the gaming currency 110 in each chip placement area, and displays the total result in the total display region 22.

[0175] 24 is a diagram showing an example of use of the inspection system according to the seventh embodiment of the present invention. In this example, a dealer places 100-dollar chips in all chip placement areas while visually checking. The area display area 21 displays that 100-dollar chips have been read for all area numbers, and the total display area 22 displays that 25 100-dollar chips have been read. The dealer can verify that there are no problems with any of the 25 gaming coins 110 by comparing the appearance of the gaming coins 110 placed on the placement table 10 with the displays in the area display area 21 and the total display area 22.

[0176] 25 is a diagram showing another example of use of the inspection system according to the seventh embodiment of the present invention. In this example, the gaming currency 110 placed in area number 14 has the amount information of 10 dollars stored in the RFID tag 111, but looks like a 100 dollar chip. The dealer determines that this gaming currency 110 is a 100 dollar chip and places it in area number 14 together with other 100 dollar chips. However, the area display region 21 displays 10 dollars only for area number 14, whereas all area numbers should display the same 100 dollars. The dealer can determine that the gaming currency 110 in area number 14 is counterfeit by checking the gaming currency 110 placed on the placement table 10 and the display in the area display region 21.

[0177] Furthermore, the gaming currency 110 placed in area number 17 does not have an RFID tag 111 built in. Therefore, no number indicating the amount is displayed in area number 17 in the area display region 21. By checking the gaming currency 110 placed on the placement table 10 and this display in the area display region 21, the dealer can determine that the gaming currency 110 in area number 17 is faulty.

[0178] Furthermore, the total display area 22 should normally display 25 100-dollar chips, but because there is a counterfeit gaming currency 110 in area number 14 and a faulty gaming currency 110 in area number 17, it shows that there are only 23 100-dollar chips and one 10-dollar chip instead, for a total of 24. By checking the gaming currency 110 placed on the placement table 10 and this display in the total display area 22, the dealer can determine that there is one counterfeit gaming currency 110 and one faulty gaming currency 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 judgment. In particular, by placing gaming currency 110 of the same amount in the chip arrangement area, it is possible to easily find counterfeit or defective gaming currency by checking the display device 20. For example, by applying different colors to the recognized types (amounts) of gaming currency 110 in the area-by-area display regions 21, the presence of gaming currency 110 of an amount different from its appearance becomes immediately obvious.

[0180] (Eighth embodiment) FIG. 26A is a cross-sectional view of a part of the placement table of the inspection system of the eighth embodiment of the present invention, and FIG. 26B is a plan view of a part of the placement table of the inspection system of the eighth embodiment of the present invention. In the placement table 10 of this embodiment, a stopper 221 for placing one gaming currency 110 in each chip placement area 220 is provided in each chip placement area 220. The stopper 221 is provided at the left end of each chip placement area 220, divided into upper and lower. Each stopper 221 has a wall 221w that rises vertically from the placement surface 120 at the left end of the chip placement area 220, and has a slope portion 221s that gently slopes from the wall 221w toward the center of the chip placement area 220. The height of the wall 221w is designed to be approximately the same as the thickness of the gaming currency 110 or slightly lower than the thickness of the gaming currency 110. Between the stoppers 221 adjacent to each other in the vertical direction, a groove 222 in which no stopper 221 is provided is formed.

[0181] 27A and 27B are diagrams showing an example of use of the inspection system according to the eighth embodiment of the present invention. When placing one gaming currency 110 in each chip arrangement area 220 of the placement table 10, the inspector picks up a stack of five gaming currency 110 of the same amount with his / her fingers, and places the gaming currency 110 one by one in each chip arrangement area 220 in the row in which the gaming currency 110 should be placed, while moving his / her hand from left to right. As shown in FIG. 27A, the bottom gaming currency 110 among the multiple gaming currency 110 held abuts against the wall 221w of the stopper 221 and cannot go any further to the right, and as shown in FIG. 27B, only the second gaming currency 110 from the bottom and those above it move to the right by the hand. This allows the gaming currency 100 to be placed smoothly row by row in each chip arrangement area 220 of the placement table 10.

[0182] By using such a stopper 221, it is easy to remove the gaming currency 110 arranged in each chip arrangement area 220 from the placement table 10. When removing the gaming currency 110, the inspector moves his / her hand from right to left, one row at a time, while placing one finger along the groove 222. The right end portion of the gaming currency 110 is pushed by the finger, and moves leftward while climbing the slope portion 221s from the left end. When the left end of the gaming currency pushed leftward reaches the top of the slope portion 221s, it covers the next gaming currency 110, and the next gaming currency 100 is pushed by the finger together with the other gaming currency and moves leftward. By repeating this, the inspector can collect the multiple gaming currency 110 arranged in a row in a stacked manner by stacking them from the bottom, simply by moving his / her hand leftward while placing his / her finger along the groove 222.

[0183] Although the first to eighth embodiments have been described above, the components of each embodiment can be combined in any manner.

[0184] In the inspection system, it is basically assumed that most gaming currency is normal. Therefore, when abnormal gaming currency is detected, the system may be configured to notify the user by sound. By outputting the inspection result by sound and / or lamp, the user can know the inspection result by sound even if the lamp is broken, for example. Also, sound is easier to check than visually. Conversely, the system may be configured to notify the user by sound when normal gaming currency is read.

[0185] In addition, when gaming currency is abnormal due to its appearance being tampered with, etc., by obtaining the reading history of the RFID tag 111 and tracking the state before the appearance was tampered with, it is possible to discover where the fraud occurred.

[0186] For gaming currency with a malfunctioning RFID tag 111 or gaming currency that does not have an RFID tag 111, the gaming currency may be disassembled and checked.

[0187] In the above embodiment, the RFID antenna is strong enough to read only one gaming currency, and is designed not to generate radio waves or magnetic fields over a long distance.

[0188] Also, counterfeit gaming currency will not be exchanged for cash, but if gaming currency with a malfunctioning RFID tag 111, gaming currency without an RFID tag 111, or gaming currency that is not normal is found, a person of high rank (such as a manager) will be called first. If the RFID tag 111 is malfunctioning or there is no tag, the RFID is identified from other IDs, and the identified RFID is deactivated or registered on a blacklist. [Explanation of symbols]
