[0009] Problems to be solved by the invention

[0010] In conventional casinos, RFID-equipped game coins are used, and by reading the RFID of the game coins located in the placement area or the game coin tray, the game coins present in a specific area are grasped, thereby preventing cheating and the like. However, when the placement area and the game coin tray, which are areas for placing game coins, are set adjacent to each other, the RFID reading devices in each area may also read the game coins placed in the other area, or the electromagnetic waves generated by each reading device may interfere with each other, making it impossible to accurately distinguish and read the game coins placed in the adjacent areas. This problem is not limited to the distinction and reading between the placement area and the game coin tray, but also applies to the upper and lower layers of a double-layer game coin tray and each layer of a coin cabinet for storing game coins, where it is also impossible to accurately distinguish and read the game coins placed in each area.

[0070] First, the game coin reading system according to the first embodiment of the present invention will be described. Figure 1 This is a schematic diagram of the reading system 101 of the present invention. The reading system 101 manages game coins by storing the game coins held by the dealer in the casino and reading the RFID tags provided on the game coins.

[0071] The reading system 101 includes a storage unit 102 for storing game coins, an antenna 104 for reading the RFID tags provided on the game coins, an RFID reader 105 for controlling the antenna 104, and a control unit 107 for grasping and managing the stored game coins based on the RFID reading result. In addition, the combination of the antenna 104 and the RFID reader 105 corresponds to a reading mechanism.

[0072] The storage unit 102 is for placing game coins. The storage unit 102 is configured to have a slot 103 for holding game coins, and the game coins are placed in the slot 103.

[0073] The reading system 101 includes: a plurality of antennas 104 that generate electromagnetic waves to form a magnetic field in order to read the RFID tags of the game coins stored in the storage unit 102, so that the RFID tags of the game coins can be read; and an RFID reader 105 that controls the antennas 104. The reading system 101 may include a plurality of RFID readers 105 or may include only one RFID reader 105. In addition, when a plurality of RFID readers 105 are provided, the plurality of RFID readers 105 can be used one by one in sequence for reading, or several of the plurality of RFID readers 105 can be used simultaneously for reading. In the present embodiment, a plurality of antennas 104 are used to read the game coins stored in the storage unit 102. Therefore, the readable range of each antenna 104 is smaller than before, and thus, the magnetic field generated by the antenna 104 can be reduced, and it is difficult to interfere with the magnetic fields generated by other reading devices for reading the game coins placed near (such as the placement area) the reading system 101. Furthermore, an effect that the influence of the electromagnetic waves generated by the antenna 104 on the body of the dealer can be expected to be reduced can also be achieved.

[0074] The antenna 104 generates electromagnetic waves to form a magnetic field Z, so that the RFID tags of the game coins existing within a specified range R can be read. The plurality of antennas 104 included in the reading system 101 may have a part where the specified ranges R readable by the respective antennas 104 overlap. In addition, the antenna 104 itself may also have an overlapping part. The specific structure of the antenna 104 will be described later.

[0075] The RFID reader 105 is connected to the antenna 104 and uses the antenna 104 to read the RFID tags. One RFID reader 105 can be connected to a plurality of antennas or can be connected to only one antenna 104. In addition, when one RFID reader uses a plurality of antennas 104, the plurality of antennas 104 can be used one by one in sequence for reading, or several of the plurality of antennas 104 can be used simultaneously for reading.

[0076] The control unit 107 is connected to the RFID reader 105 and determines and manages the IDs of the game coins stored in the storage unit 102 based on the reading results obtained by using the RFID reader 105. Furthermore, information such as the types, amounts, and numbers of the game coins stored in the storage unit 102 can be grasped according to the determined IDs, and the grasped information can also be stored.

[0077] Next, use Figure 2 to describe the specific structure of the antenna 104.Figure 2 The wiring of the antenna 104 showing the first embodiment of the present invention. The antenna is preferably disposed above or below the storage unit 102. Further, a substrate (not shown) on which the antenna is disposed may be disposed below the storage unit 102 to provide the antenna 104, or the antenna 104 may be directly provided on the storage unit 102 without using a substrate.

[0078] In Figure 2 the configuration example of, a structure is shown in which two antennas 104a and 104b can be used to read RFID tags of game coins located within the same range. In this configuration example, since the antennas 104a and 104b have the same structure, the structure of the antenna will be described first using the antenna 104a. The antenna 104a includes a plurality of wirings 108 extending in a predetermined direction (lateral direction in the figure), and the wirings 108 of the antenna 104a extending in the predetermined direction are arranged more densely than conventional antennas. In such a configuration, it is preferable to provide three or more wirings 108 extending in the predetermined direction. Since the wirings 108 extending in the predetermined direction are densely present, the number of game coins that can be read by the magnetic fields formed by the wirings 108 extending in each predetermined direction becomes smaller. Therefore, each magnetic field generated by the wiring 108 in the predetermined direction can be made smaller, and it is less likely to cause magnetic field interference with other reading devices for reading game coins placed near (such as a placement area) the reading system 101. Further, an effect of reducing the influence of the electromagnetic wave generated by the antenna 104a on the body of the dealer can also be expected.

[0079] The above structure is not limited to Figure 2 the configuration as in the configuration example of, and for example, it can also be achieved by arranging the wiring in a spiral shape.

[0080] Furthermore, in Figure 2 the configuration example of, the wirings of the antenna 104a extending in the predetermined direction form a dense portion and a sparse portion. When current flows through the antenna 104a, the directions 1A of the currents flowing through the wirings included in each dense portion are the same direction, so the magnetic fields generated by the respective wirings do not cancel each other out. In addition, when the directions 1A of the currents flowing through the wirings on both sides of the sparse portion are opposite, the directions of the magnetic fields extending in the front-rear direction are different, so an effect that the magnetic field does not extend beyond the degree of cancellation can also be expected. Further, the directions of the magnetic fields extending in the up-down direction are the same, so an effect that it becomes easier to read even when the game coin C is in a fallen state can be expected.

[0081] Furthermore, in Figure 2 the configuration example of, it is a structure for using two antennas 104a and 104b to read game coins within the same range. By using these antennas at staggered times, the reading of each antenna does not interfere, and the possibility of missing the reading of the RFID tag is reduced. The processing in the case where two antennas 104a and 104b read the same game coin will be described later.

[0082] In Figure 3 the configuration shown, the wiring 108 extending in a specified direction extends in a direction orthogonal to the stacking direction of the game coins C placed in the storage section 102. By adopting such a configuration, the magnetic field Z generated by the antenna 104 expands in a direction orthogonal to the RFID tag T provided on the game coin C placed in the storage section 102, and thus, the RFID tag T can be easily read.

[0083] In the case of adopting such a configuration, when the number of game coins C placed in the storage section 102 reaches the maximum, the number of game coins C that can be read by the magnetic field Z formed by the wiring 108 in each specified direction is preferably 8 or less in the direction orthogonal to the wiring 108 in the specified direction. These structures can be realized by the wiring 108 extending in a specified direction included in one antenna 104, or can be realized by combining the wiring 108 extending in a specified direction included in a plurality of antennas.

[0084] On the other hand, in Figure 4 , the wiring 108 extending in a specified direction ( Figure 4 longitudinal in this case) extends in a direction orthogonal to the boundary of the placement area B where the game coins are placed, which is located near the storage section 102 and the storage device, and the wiring 106 in the specified direction is arranged in a striped pattern throughout the storage section 102. By adopting such a configuration, the magnetic field Z generated by the antenna 104 of the reading device 101 is not easily expanded in the direction toward the placement area B, and thus, it is not easy to read the RFID tag provided on the game coin C placed in the placement area B. Furthermore, it is not easy to generate magnetic field interference with other reading devices for reading the game coins placed in the placement area B, and accurate reading can be performed even when the reading device 101 and other reading devices are used simultaneously.

[0085] Regarding Figure 5 the process executed by the control unit 107 in the case of performing reading using different antennas 104 and repeatedly reading the same game coin will be described. The reading result Y11 represents the ID of the game coin C read by using the first antenna 104. The reading result Y12 represents the ID of the game coin C read by using a second antenna 104 different from the first antenna 104. The control unit 107 obtains the reading result Y13 by determining that there is one game coin C assigned with the ID included in at least any one of the reading results Y11 and Y12, and thus grasps the ID of the game coin C stored in the storage section 102.

[0086] A coin recycling storage unit can be provided adjacent to the above-mentioned storage unit 102. The coin recycling storage unit has a slot with the same structure as the slot 103 of the storage unit 102. The slot of the coin recycling storage unit is formed to extend in a direction parallel to the slot 103 of the storage unit 102. The coin recycling storage unit is used to temporarily store the game coins recycled from the player. The coin recycling storage unit is provided with an antenna for recycling game coins, which is different from the multiple antennas 104 provided corresponding to multiple partial areas of the storage unit 12. It should be noted that the slot of the coin recycling storage unit can be formed to extend in a direction perpendicular to the multiple slots 103 of the storage unit 102.

[0087] In the reading system 101, a shielding member is provided between the storage unit 102 and the coin recycling storage unit. Through this shielding member, it is possible to prevent the multiple antennas 104 provided corresponding to multiple partial areas of the storage unit 102 from reading the RFID tags of the game coins in the coin recycling storage unit. In addition, through the shielding member, it is possible to prevent the antenna for recycling game coins from reading the RFID tags of the game coins in the storage unit 102. Thus, it is possible to distinguish and read the game coins (recycled game coins) stored in the coin recycling storage unit from the game coins stored in the storage unit 102.

[0088] The RFID tag built into the game coin stores at least the ID assigned to the game coin. The multiple antennas 104 provided corresponding to multiple partial areas of the storage unit 102 are configured not to read the RFID tags of the game coins in the coin recycling storage unit. In addition, the control unit 107 determines the IDs of the game coins stored in the storage unit 102 and the coin recycling storage unit. When the ID read by the antenna 104 of the storage unit 102 duplicates the ID read by the antenna for recycling game coins, the control unit 107 determines that the game coin assigned with this ID exists in the storage unit 102.

[0089] Alternatively, the antenna for recycling game coins can be configured not to read the RFID tags of the game coins in the storage unit 102. In this case, when the ID read by the antenna 104 of the storage unit 102 duplicates the ID read by the antenna for recycling game coins, the control unit 107 determines that the game coin assigned with this ID exists in the coin recycling storage unit.

[0090] (Second Embodiment)

[0091] Next, a game coin reading system according to a second embodiment of the present invention will be described. Figure 6 It is a schematic diagram of a reading system 201 of the present invention. The reading system 201 is used to read the RFID tags of the game coins C placed on the gaming table by the game participants P in the casino, so as to manage the game coins C.

[0092] The reading system 201 includes: a placement area B for a game participant P to place game coins C; a storage area 209 for holding game coins C owned by a dealer D; an antenna 204 for reading an RFID tag provided on the game coin C; an RFID reader 205 for controlling the antenna 104; and a control unit 207 for grasping and managing the stored game coins C based on a reading result obtained by using the RFID reader 205. It should be noted that the combination of the antenna 204 and the RFID reader 205 corresponds to a reading mechanism.

[0093] The placement area B is for a game participant P to place game coins C. Multiple player positions can be set in the placement area, or placement areas different for each placement object can be set at each player position.

[0094] The storage area 209 is for holding game coins C owned by a dealer D. The storage area 209 can be a game coin tray or a storage vault.

[0095] The reading system 201 includes: multiple antennas 204 that generate electromagnetic waves to form a magnetic field in order to read the RFID tag of the game coin C placed in the placement area B, so that the RFID tag of the game coin C can be read; and an RFID reader 205 for controlling the antenna 204. The reading system 201 can include multiple RFID readers 205, or can include only one RFID reader 205.

[0096] The antenna 204 generates electromagnetic waves to form a magnetic field, so that the RFID tag provided on the game coin C existing within a specified range can be read. The multiple antennas 204 included in the reading system 201 can have a part where the specified ranges readable by the respective antennas 204 overlap, and the antennas 204 themselves can also be arranged in an overlapping manner. The specific structure of the antenna 204 will be described later.

[0097] The RFID reader 205 is connected to the antenna 204 and uses the antenna 204 to read the RFID tag. One RFID reader 205 can be connected to multiple antennas, or can be connected to only one antenna 204. In addition, when one RFID reader uses multiple antennas 204, the multiple antennas 204 can be used for reading one by one in sequence, or several of the multiple antennas 204 can be used for reading simultaneously.

[0098] The control unit 207 is connected to the RFID reader 205, and based on the reading result obtained by using the RFID reader 205, it determines and manages the ID of the game coins C placed in the placement area B. Furthermore, information such as the type, amount, and number of game coins C placed in the placement area B can be grasped according to the determined ID, and the grasped information can also be stored. Furthermore, the grasped information is compared with the ID, type, number, amount, etc. of the game coins C determined by other methods such as a camera, and it is determined whether there is an abnormality, and an alarm is issued when an abnormality occurs.

[0099] Next, Figure 7 the specific configuration of the antenna 204 will be described. Figure 7 The wiring of the antenna 204 showing the second embodiment of the present invention. The antenna 204 includes wiring 208a in the direction crossing the boundary and wiring 208b in the direction along the boundary. In the present embodiment, the total length of the wiring 208a in the direction crossing the boundary included in the antenna 204 is greater than the total length of the wiring 208b in the direction along the boundary. By adopting such a configuration, the magnetic field generated by the antenna is not easily extended in the direction of the storage area and the direction of the dealer D. Therefore, the possibility of reading the game coins in the storage area 209 is reduced. Moreover, an effect of reducing the influence on the body of the dealer D can also be expected.

[0100] In addition, in Figure 7 one of the wirings 208a in the direction crossing the boundary of the antenna 204 of the present invention is configured to cross over another wiring 208a in the direction crossing the boundary, thereby forming an "8" shape. If such a configuration is adopted, in the adjacent wirings 208a in the crossing direction, the direction 2A of the current flowing when the current flows is the same, so the generated magnetic fields do not cancel each other. Furthermore, in the adjacent wirings 208b in the direction along the boundary, the direction 2A of the current flowing when the current flows is opposite, so the generated magnetic fields cancel each other, and an effect of further reducing the influence on the storage area 209 can be expected.

[0101] Regarding Figure 8 the processing performed by the control unit 207 in the case of repeatedly reading the same game coin during the reading using different antennas 204 will be described. The reading result Y21 represents the ID of the game coin C read by using the first antenna 204. The reading result Y22 represents the ID of the game coin C read by using a second antenna 204 different from the first antenna 204. The control unit 207 determines that there is one game coin C assigned with the ID included in at least any one of the reading results Y21 and Y22 in the placement area B, and obtains the reading result Y23, thereby grasping the ID of the game coin C stored in the placement area B.

[0102] Furthermore, the reading system 201 may include mechanisms for acquiring game information, such as a camera 212 and a win / loss determination device 213. By comparing the state of the game coins C on the placement area B obtained using these mechanisms, the state of the progress of the game, and the state of the game coins C on the placement area B obtained using the RFID reader 205, it is determined whether there is an abnormality. In the case of an abnormality, the control unit 207 issues an alarm.

[0103] (Third Embodiment)

[0104] Next, a reading system for game coins according to the third embodiment of the present invention will be described. Figure 9 It is a schematic diagram of the reading system 301 of the present invention. The reading system 301 is used to read the RFID tags of the game coins C owned by the dealer and stored in the storage unit 302 and the RFID tags of the game coins C placed by the game participant P on the placement area B in the casino, so as to distinguish and manage whether the game coins C are located in the storage unit 302 or on the placement area B.

[0105] The reading system 301 includes: a placement area B for the game participant P to place the game coins C; a storage area 302 for holding the game coins C owned by the dealer D; a placement area reading mechanism 305 for reading the RFID tags of the game coins C placed on the placement area B; a storage area reading mechanism 304 for reading the RFID tags of the game coins C stored in the storage area 302; and a control unit 303 for grasping and managing the stored game coins C based on the reading results of the RFID tags of the game coins C existing in each area.

[0106] The storage area 302 is used to store the game coins C owned by the dealer D.

[0107] The reading system 301 has: a storage area reading mechanism 304 for reading the RFID tags of the game coins C stored in the storage area 302; and a placement area reading mechanism 305 for reading the RFID tags of the game coins C placed on the placement area B. It should be noted that the storage area reading mechanism 304 and the placement area reading mechanism 305 respectively correspond to the combination of the antenna and the RFID reader in the first embodiment and the second embodiment. The storage area reading mechanism 304 and the placement area reading mechanism 305 do not perform control to stagger the reading times or synchronize the reading times, and can be controlled independently. Even if the reading is performed at the same time, the RFID tags of the game coins C placed in each area can be read.

[0108] The specific structures of the storage area reading mechanism 304 and the placement area reading mechanism 305 are the same as those of the first embodiment and the second embodiment of the present invention, respectively, and thus their descriptions are omitted.

[0109] The storage area reading mechanism 304 and the placement area reading mechanism 305 can be configured to repeatedly perform reading at a specified time, and the reading results can be stored in the control unit 303.

[0110] The control unit 303 is connected to the storage area reading mechanism 304 and the placement area reading mechanism, and determines the ID of the game coin C placed in each area based on the reading results of the storage area reading mechanism 304 and the placement area reading mechanism. Furthermore, the control unit 303 can be configured to be able to grasp the increase and decrease of the game coin C placed in each area according to the history of the information of the game coin C determined based on the reading results of the storage area reading mechanism 304 and the placement area reading mechanism 305.

[0111] Furthermore, when the ID that disappears in one area is read in another area according to the ID of the game coin C determined based on the reading result, the control unit 303 determines that the game coin C assigned with this ID has moved from one area to another area.

[0112] Furthermore, the control unit 303 can determine the game coin C that moves from the placement area B to the storage area 302 at a specified time as a recycled game coin, and can determine the game coin C that moves from the storage area 302 to the placement area B at a specified time as a repaid game coin. In addition, events such as the purchase, exchange, and redemption of the game coin C can also be determined based on the information of the disappearance, appearance, movement of the game coin C in each area and the area and time when the disappearance, appearance, and movement occur.

[0113] Furthermore, the reading system 301 can include mechanisms for acquiring game information such as a camera 306 and a win / loss judgment device 307. When there is a difference between the state of the game obtained by these structures and the recycled game coins, repaid game coins, etc. determined by the reading mechanisms in each area, the control unit 303 issues an alarm.

[0114] Next, the game coin reading system according to the fourth embodiment of the present invention will be described. Figure 10 It is a schematic diagram of the reading system 401 of the present invention. The reading system 401 is used to read the RFID tag possessed by the game coin C placed in the double-layer game coin tray on the gaming table by the dealer D in the casino, so as to manage based on whether the game coin C is located in the upper layer or the lower layer of the double-layer game coin tray.

[0115] The coin reading system 401 includes: an upper storage unit 402 and a lower storage unit 403 for storing game coins C; an upper reading mechanism 404 and a lower reading mechanism 405 for reading the RFID tags of the game coins C; and a control unit 406 that grasps and manages the stored game coins C based on the reading results of the RFID tags. It should be noted that in this embodiment, the upper reading mechanism and the lower reading mechanism refer to a combination of an antenna for reading the RFID tag and an RFID reader for controlling the antenna.

[0116] Figure 11 This is an external view of the double-layer game coin tray used by the coin reading system 401. The upper storage unit 402 is configured to be movable, and the upper storage unit 402 can achieve two states, namely, a state in which the upper storage unit 402 overlaps above the lower storage unit 403 and the lower storage unit 403 is closed, and a state in which the upper storage unit 402 is located at a position other than above the lower storage unit 403 and the lower storage unit 403 is open. The coin reading system 401 may have detection devices (not shown) such as sensors and buttons for detecting the open / closed state of the lower storage unit 403.

[0117] The upper storage unit 402 and the lower storage unit 403 may be provided with slots 407 for holding the game coins C, or may store the game coins C in a stacked manner without the slots 407. In addition, the game coins C may also be stored in a state of being placed in a game coin box CC.

[0118] The upper reading mechanism 404 reads the RFID tags of the game coins C stored in the upper storage unit 402. The lower reading mechanism 405 reads the RFID tags of the game coins C stored in the lower storage unit 403.

[0119] The control unit 406 is connected to the upper reading mechanism 404 and the lower reading mechanism 405, and based on these reading results, determines and manages the IDs of the game coins C stored in the upper storage unit 402 and the lower storage unit 403. Furthermore, according to the determined IDs, information such as the types, amounts, and numbers of the game coins C stored in the upper storage unit 402 and the lower storage unit 403 can be grasped, and the grasped information can also be stored.

[0120] In this embodiment, the upper reading mechanism 404 is configured to read the RFID tags of the game coins C stored in the upper storage unit 402, but not the RFID tags of the game coins C stored in the lower storage unit 403, or the lower reading mechanism 405 is configured to read the RFID tags of the game coins C stored in the lower storage unit 403, but not the RFID tags of the game coins C stored in the upper storage unit 402.

[0121] For a structure that does not read the game coins C placed in one of the two storage parts, as described in the first embodiment of the present invention, a structure that reduces the magnetic field generated by each antenna by using multiple antennas, or a structure that reduces the magnetic field generated by each wiring by arranging the wirings densely can be adopted. Or, an electrostatic shield, a magnetic shield, etc. (not shown) can be provided between the upper storage part 402 and the lower storage part 403 by using an aluminum plate, a ferrite sheet, etc. Or, in a state where the lower storage part 403 is open, another storage part can be provided outside the reading area of one reading mechanism, and reading can be performed in a state where the lower storage part 403 is open, so as not to read the game coins C in the other storage part. Furthermore, the above methods can also be used in combination.

[0122] Next, use Figure 12 to illustrate the method of distinguishing between the game coins C placed in the upper storage part 402 and the game coins C placed in the lower storage part 403 in this embodiment.

[0123] Figure 12 The structure in which the upper reading mechanism 404 does not read the RFID tag of the game coin C stored in the lower storage part 403 is shown. The control part 406 determines the ID of the game coin C stored in the upper storage part 402 based on the reading result Y41 of the upper reading mechanism 404, and compares the reading result Y41 of the upper reading mechanism 404 with the reading result Y42 of the lower reading mechanism 404. It is considered that the game coin C assigned with the ID read by both the upper reading mechanism 404 and the lower reading mechanism 405 is stored in the upper storage part C. Therefore, by subtracting the reading result of the upper reading mechanism 404 from the reading result of the lower reading mechanism 405, the determination result Y43 of the ID of the game coin C stored in the lower storage part 403 can be obtained.

[0124] Even when the lower reading mechanism 405 is a structure that does not read the RFID tag of the game coin C stored in the upper storage part 402, similarly, the control part determines the ID of the amusement substitute C stored in the lower storage part 403 based on the reading result of the lower reading mechanism, compares the reading result of the upper reading mechanism 404 with the reading result of the lower reading mechanism, and subtracts the latter from the former, so as to obtain the determination result of the ID of the game coin C stored in the upper storage part 402.

[0125] Next, the game coin reading system of the fifth embodiment of the present invention will be described. Figure 13 It is a schematic diagram of the reading system 501 of the present invention. The reading system 501 is used to manage game coins C stored in a vault having storage parts divided into multiple layers in a casino by reading the RFID tags provided on the game coins C, based on distinguishing which layer of the vault the game coins C are stored in.

[0126] The coin reading system 501 includes: an upper storage section 502 and a lower storage section 503 for storing game coins C; upper reading mechanisms 504 and 505 for reading the RFID tags provided on the game coins C; and a control section 506 that grasps and manages the stored game coins C based on the reading results of these reading mechanisms. It should be noted that in this embodiment, the upper reading mechanism and the lower reading mechanism refer to a combination of an antenna for reading the RFID tag and an RFID reader for controlling the antenna.

[0127] The coin reading system 501 has an upper storage section 502 and a lower storage section 503. The upper storage section 502 and the lower storage section 503 are each independently openable and closable structures. In addition, the coin reading system 501 may also have detection devices (not shown) such as sensors and buttons for detecting the open / closed states of the upper storage section 502 and the lower storage section 503 respectively.

[0128] The upper storage section 502 and the lower storage section 503 may have slots (not shown) for holding the game coins C, or may store the game coins C in a stacked manner without slots. In addition, the game coins C may also be stored in a state of being placed in a coin box CC.

[0129] The coin reading system 501 has an upper reading mechanism 504 and a lower reading mechanism 505. The upper reading mechanism 504 reads the RFID tag of the game coin C stored in the upper storage section 502. The lower reading mechanism 505 reads the RFID tag of the game coin C stored in the lower storage section 503.

[0130] The control section 506 is connected to the upper reading mechanism 504 and the lower reading mechanism 505, and determines and manages the IDs of the game coins C stored in the upper storage section 502 and the lower storage section 503 based on the reading results of these reading mechanisms. Furthermore, information such as the type, amount, and number of the stored game coins C can be grasped according to the determined IDs, and the grasped information can also be stored.

[0131] In this embodiment, the upper reading mechanism 504 can read the RFID tag of the game coin C stored in the upper storage section 502 without reading the RFID tag of the game coin C stored in the lower storage section 503, or the lower reading mechanism 505 can read the RFID tag of the game coin C stored in the lower storage section 503 without reading the RFID tag of the game coin C stored in the upper storage section 502.

[0132] For a structure that does not read the game coins C placed in one of the above two storage parts, as described in the first embodiment of the present invention, a structure that uses multiple antennas to reduce the magnetic fields generated by each antenna, or a structure that densely arranges the wiring to reduce the magnetic fields generated by each wiring can be adopted. Or, an electrostatic shield, a magnetic shield, etc. (not shown) can be provided between the upper storage part 502 and the lower storage part 503 using an aluminum plate or a ferrite sheet. Or, it can be configured such that, in a state where one storage part is open, another storage part is provided outside the reading area of one reading mechanism, and reading is performed in a state where one storage part is open, so as not to read the game coins C in the other storage part. Furthermore, these methods can also be used in combination.

[0133] Next, use Figure 14 to explain the method of distinguishing the game coins C placed in the upper storage part 502 and the game coins C placed in the lower storage part 503 in this embodiment.

[0134] Figure 14 The structure in which the upper reading mechanism 504 does not read the RFID tags of the game coins C stored in the lower storage part 503 is shown. The control unit 506 determines the ID of the game coins C stored in the upper storage part 502 based on the reading result Y51 of the upper reading mechanism 504. In addition, the reading result Y51 of the upper reading mechanism 504 is compared with the reading result Y52 of the lower reading mechanism 505. It is considered that the game coins C assigned with the ID read by both the upper reading mechanism 304 and the lower reading mechanism 505 are stored in the upper storage part C. Therefore, by subtracting the reading result of the upper reading mechanism 504 from the reading result of the lower reading mechanism 505, the determination result Y53 of the ID of the game coins C stored in the lower storage part 503 can be obtained.

[0135] Even in the case of a structure in which the lower reading mechanism 505 does not read the RFID tags of the game coins C stored in the upper storage part 502, similarly, the control unit determines the ID of the amusement substitute C stored in the lower storage part 503 based on the reading result of the lower reading mechanism, compares the reading result of the upper reading mechanism 504 with the reading result of the lower reading mechanism, and subtracts the latter from the former, thereby obtaining the ID of the game coins C stored in the upper storage part 502.
