DETAILED DESCRIPTION OF NON-LIMITING EXAMPLE EMBODIMENTS

[0055] FIG. 1 is a perspective view illustrating a game token money according to an embodiment of the invention. The game token money 10 according to this embodiment is manufactured by laminating a plurality of plastic sheet-shaped members, performing thermocompression bonding, and then punching in a circular shape. For this purpose, as illustrated in FIG. 1, the game token money 10 has a layered structure obtained by laminating a plurality of layers in a thickness direction. The layered structure obtained by laminating a plurality of sheet-shaped members is exposed on a side face of the game token money 10 to form a stripe pattern in a layering direction.

[0056] The game token money 10 has a layered structure including a colored layer 12 as a middle layer and pale color layers 11 as surface layers on both sides by interposing the colored layer 12. The front face of the pale color layer 11 can be visually recognized from the outside. The color of the colored layer 12 corresponds to a value of the game token money 10 (such as twenty dollars, one hundred dollars, and one thousand dollars). That is, the game token money 10 has the colored layer 12 having a color different depending on its value. The pale color layer 11 has a color not denser than any color of the colored layer 12, and has a common color for a plurality of classifications of values. The pale color layer 11 typically has a white color. Therefore, the value of the game token money 10 can be specified by the color of the colored layer 12 by observing the side face.

[0057] Printing is performed on the front face of the pale color layer 11 as described below, and a transparent layer is provided thereon. Therefore, the printing on the front face of the pale color layer 11 can be visually recognized through the transparent layer. Notches 11a are provided on the outer edge of the pale color layer 11. Classification parts 13 are filled in the notches 11a of the pale color layer 11. A plurality of classification parts 13 are arranged at an equiangular interval in the circumferential direction (rotation direction) along the outer edge of the game token money 10. In the example of FIG. 1, four classification parts 13 are arranged at an angular interval of 90°.

[0058] Value information, identification information, and classification information are given to the game token money 10. Here, the value information is information indicating a value of the game token money 10 (such as ten dollars, twenty dollars, one hundred dollars, and one thousand dollars), and the identification information is unique information capable of identifying each game token money 10. The classification information is information indicating a classification of each game token money 10 other than the value. The classification information may include, for example, any one of information for distinguishing whether the game token money 10 is a rolling chip or a cash chip, junket information differently set for each junket to specify a junket, and casino information differently set for each casino to specify the casino.

[0059] The value information, the identification information, and the classification information can be visually recognized on the front face of the game token money 10. Specifically, the value information is written as numerals 17 on the front face of the game token money 10. The identification information is coded and written as marks 14 and 15 on the front face of the game token money 10. In addition, the classification parts 13 are colored depending on the classification, and the classification information is expressed by a color of the classification part 13. Note that the color of the classification part 13 is different from any color of the colored layer 12. Therefore, a classification of the game token money 10 can be specified by the color of the classification part 13.

[0060] The value information and the classification information can be visually recognized on the side face of the game token money 10. Specifically, the value information is expressed by the color of the colored layer 12 observed on the side face of the game token money 10. In addition, the classification part 13 indicating the classification information using the color can also be visually recognized on the side face.

[0061] The identification information is stored in a radio-frequency identification (RFID) chip 16 (hereinafter, simply referred to as an “RFID”) embedded in the game token money 10. Therefore, by reading the game token money 10 using the RF reader, it is possible to read the identification information stored in the RFID 16.

[0062] In this manner, the value information and the identification information are given to the game token money 10 in a plurality of forms. However, a plurality of pieces of value information and identification information given to true game token moneys match each other. In addition, a relationship between the identification information, the value information, and the classification information is stored in a database. As the identification information is specified by the marks 14 and 15 or the RFID 16, the value information and the classification information corresponding to this identification information can be specified by referencing the database.

[0063] Next, a method of manufacturing the game token money 10 will be described. FIG. 2 is a flowchart illustrating the method of manufacturing the game token money 10. First, the numerals 17 indicating the value information, the marks 14 and 15, and other patterns are printed on the plastic sheet-shaped member 110 of the pale color layer 11 serving as a surface layer (step S21). As described below, the game token money 10 is manufactured by punching the sheet-shaped member, and a plurality of game token moneys 10 are obtained from a single sheet-shaped member. Accordingly, printing is performed to match the game token moneys 10 within a plurality of punching target ranges 111 of the sheet-shaped member 110 serving as the surface layer.

[0064] Next, in order to form blank portions 112 for filling the classification part members 131 in the sheet-shaped member 110 of the surface layer, punching is performed to match shapes of the classification part members 131 (step S22). FIG. 3 is a top plan view illustrating the sheet-shaped member 110 serving as the surface layer. As illustrated in FIG. 3, a plurality of punching target ranges 111 are provided on the sheet-shaped member 110. Although not illustrated in FIG. 3, printing is performed to match the game token moneys 10 within the punching target ranges 111. The blank portions 112 are formed to intersect the outer edge of the punching target range 111 across the inside and the outside of each punching target range 111. According to this embodiment, as described above, the classification parts 13 are filled at an equiangular interval of 90°. Accordingly, four blank portions 112 are formed at an equiangular interval of 90° along the outer circumferential direction of the outer edge of the punching target range 111.

[0065] Meanwhile, the classification part member 131 filled in the blank portion 112 is also fabricated by punching the plastic sheet-shaped member 130. FIG. 4 is a top plan view illustrating the sheet-shaped member 130 for fabricating the classification part member 131. The sheet-shaped member 130 has the same thickness as that of the sheet-shaped member 110 serving as the surface layer and a color different from that of the sheet-shaped member 110. As illustrated in FIG. 4, the classification part members 131 shaped to match the blank portions 112 are punched out from the sheet-shaped member 130.

[0066] FIG. 5 is a perspective view illustrating the classification part member 131 obtained by punching the sheet-shaped member 130. As illustrated in FIGS. 3 to 5, the blank portion 112 and the classification part member 131 filled in the blank portion 112 have a substantial rectangular shape with both longitudinal ends being rounded and are symmetric vertically and horizontally.

[0067] Then, the classification part member 131 obtained by punching the sheet-shaped member 130 is filled in the blank portion 112 of the sheet-shaped member 110 serving as the surface layer (step S23). FIG. 6 is a top plan view illustrating the sheet-shaped member 110 filled with the classification part members 131. Note that the classification part members 131 are compressively bonded to the sheet-shaped member 110 and the sheet-shaped member 120 serving as the colored layer 12 in a thermocompression bonding process described below. Therefore, in this filling process, the classification part member 131 is not necessarily bonded to the sheet-shaped member 110.

[0068] Then, a plurality of sheet-shaped members including the sheet-shaped members 110 and 120 filled with the aforementioned classification part members 131 are laminated (step S24). FIG. 7 is a diagram illustrating lamination of a plurality of sheet members. According to this embodiment, the colored layer 12 is formed by a pair of sheet members 120. The RFID 16 is arranged in the center of the punching target range 111 between a pair of sheet members 120 serving as the colored layers 12.

[0069] The sheet member 110 having the blank portion 112 filled with the classification part member 131 (classification part insertion layer) is laminated on both outer sides of a pair of sheet member 120 interposing the RFID 16 such that each print layer 113 faces the outside. In addition, a transparent layer 170 serving as a protection layer is laminated on the outside of each of a pair of classification part insertion layers. Note that, although each layer is spaced in FIG. 7, a plurality of layers are overlapped without a gap in the lamination process (step S24).

[0070] Thermocompression bonding is performed while a plurality of sheet members are laminated in this manner (step S25). Through this thermocompression bonding, the layers neighboring each other are compressively bonded to form a multilayered lamination plate 100 as a whole. The RFID 16 is embedded between a pair of sheet members 120 as the sheet member 120 is thermally deformed.

[0071] Then, the game token money 10 is punched out from the multilayered lamination plate 100 (step S26). FIG. 8 is a top plan view illustrating the multilayered lamination plate 100 subjected to the punching and the game token money 10 obtained by the punching. As described above, the classification part member 131 is arranged to intersect the outer edge of the punching target range 111 of each game token money 10. Therefore, the classification part member 131 is cut along the outer edge (punching line) of the punching target range 111 which crosses the classification part member 131.

[0072] As a result, the blank portion 112 forms a notch 11a, so that the game token money 10 illustrated in FIG. 1 is obtained as the cut classification part 13 is filled in the notch 11a. The cutting section of the classification part 13 is exposed on the side face of the pale color layer 11. Therefore, the classification part 13 can be visually recognized from both the front face side and the side face side. In this manner, the classification part 13 filled in the notch 11a formed in the outer edge of the pale color layer 11 serving as a surface layer makes a color change in the circumferential direction as the pale color layer 11 of the game token money 10 is observed from the side face.

[0073] Note that the printing on the surface layer may be performed after punching the game token money 10. In this case, a clear coating serving as a protection layer may be applied to the print layer subjected to the printing.

[0074] Next, an inspection system for inspecting the game token money 10 manufactured as described above will be described. FIG. 9 is a block diagram illustrating a configuration of the inspection system according to this embodiment. The inspection system 50 includes a game token money 10, cameras 51 and 52, and a RF reader 53.

[0075] FIG. 10 is a diagram illustrating an installation example of the camera 51. FIG. 11 is a diagram illustrating an installation example of the camera 52 and the RF reader 53. The camera 51 is installed over the table Tb as illustrated in FIG. 10. The camera 51 has an optical system 511 configured and arranged to photograph the front face of the game token money 10 placed on the table Tb. The camera 51 creates an image (front face image) by photographing the front face of the game token money 10 using the optical system 511.

[0076] As illustrated in FIG. 11, the camera 52 is installed over a chip tray Tr. The camera 52 has an optical system 521 configured and arranged to photograph the side face of the game token money 10. The camera 52 creates an image (side face image) by photographing the side face of the game token money 10 using the optical system 521. In addition, the RF reader 53 has an antenna 531 configured and arranged to transmit radio waves to the RFID 16 of the game token money 10 and receive the radio waves from the RFID 16. As illustrated in FIG. 11, the RF reader 53 reads information stored in the RFID 16 of the game token money 10 housed in the chip tray Tr using the antenna 531.

[0077] The inspection system 50 further includes a recording device 54, an inspection device 55, a database 56, and an output device 57. The recording device 54 records the front face image obtained from the camera 51, the side face image obtained from the camera 52, and the information read by the RF reader 53. The inspection device 55 performs inspection on the basis of the image or information recorded on the recording device 54.

[0078] As described above, the value information is expressed by writing numerals 17 in the center on the front face of the game token money 10, and the identification information is expressed by the marks 14 and 15. The classification information is expressed by the color of the classification part 13. The inspection device 55 recognizes each of the value information, the identification information, and the classification information by performing an image recognition processing for the front face image. Note that this image recognition processing may also be performed using a neural network.

[0079] The value information is expressed by the color of the middle layer (colored layer 12) on the side face of the game token money 10, and the classification information is expressed by the color of the classification part 13. The inspection device 55 recognizes each of the value information and the classification information by performing an image recognition processing for the side face image. In addition, this image recognition processing may also be performed using a neural network.

[0080] The database 56 stores the value information and the classification information in association with the identification information. The inspection device 55 specifies the value information and the classification information stored in association with the identification information by referencing the database 56 when the identification information is specified on the basis of the marks 14 and 15 from the front face image of the camera 51. The inspection device 55 compares the value information and the classification information specified in this manner with the value information and the classification information, respectively, specified on the basis of the numerals and the color of the classification part 13 from the front face image of the camera 51 and determines whether or not they match each other, that is, whether or not the game token money 10 is true or false. If they do not match each other, that is, if the game token money 10 is falsified, the output device 57 outputs a warning. The output device 57 may include a buzzer or a lamp for outputting the warning.

[0081] Meanwhile, the inspection device 55 specifies the value information and the classification information stored in association with the identification information by referencing the database 56 when the RF reader 53 reads the identification information stored in the RFID 16. The inspection device 55 compares the value information and the classification information specified in this manner with the value information and the classification information, respectively, specified on the basis of the color of the colored layer 12 and the color of the classification part 13 from the side face image of the camera 52 and determines whether or not they match each other, that is, whether or not the game token money 10 is true or false. If they do not match each other, that is, if the game token money 10 is falsified, the output device 57 outputs a warning.

[0082] As described above, according to this embodiment, a portion (classification part 13) visually recognizable from both the front face side and the side face side in a part of the circumferential direction is formed in the game token money 10 having the layered structure. For example, the classification information can be expressed using the color of this portion. Since this classification information can be visually recognized from both the front face side and the side face side, it is possible to recognize the classification information using both the camera that photographs the front face such as the camera 51 and the camera that photographs the side face such as the camera 52.

[0083] A method of manufacturing the game token money 10 according to a modification of the aforementioned embodiment will now be described. FIG. 12 is a top plan view illustrating the sheet-shaped member 110 filled with classification part members 1311 according to a modification of the embodiment in conjunction with FIG. 6. In this example, one classification part member 1311 is shared by the neighboring game token moneys 10. That is, one end portion of the classification part member 1311 corresponds to the classification part 13 of one game token money 10 by punching, and the other end portion corresponds to the classification part 13 of the game token money 10 neighboring to the one game token money 10 by punching. According to this modification, it is possible to reduce the number of the classification part members filled in the sheet-shaped member 110, which is advantageous in reduction of the manufacturing cost.

[0084] FIG. 13 is a top plan view illustrating the sheet-shaped member 110 filled with classification part members 1312 according to a modification of the embodiment in conjunction with FIG. 6. In this example, a single classification part member 1312 is formed by connecting the classification part members 1311 arranged in a vertical direction to each other. FIG. 14 is a top plan view illustrating a sheet-shaped member 130 for fabricating classification part members 1312 in conjunction with FIG. 4. FIG. 15 is a perspective view illustrating classification part members 1312 obtained by punching the sheet-shaped member 130. In this manner, by connecting a plurality of classification part members 1311, it is possible to reduce the number of the classification part members filled in the sheet-shaped member 110, which is advantageous in reduction of the manufacturing cost.

[0085] FIG. 16 is a top plan view illustrating the sheet-shaped member 110 filled with a classification part member 1313 according to a modification of the modification in conjunction with FIG. 6. In this example, a single classification part member 1313 is formed by connecting the classification part members 1311 arranged in the vertical direction and the horizontal direction to each other. That is, the classification part member 1313 is formed by connecting all of the classification part members 1311 excluding the classification part member 131 filled in the peripheral portion of the sheet-shaped member 110. In this example, it is possible to further reduce the number of the classification part members, which is advantageous in reduction of the manufacturing cost.

[0086] Next, a modification of the classification part will be described. FIG. 17 is a perspective view illustrating the game token money 10 filled with the classification parts 13′ according to a modification. The classification part 13′ includes a center part 138 and side parts 139 interposing the center part 138. In this classification part 13′ according to this modification, two types of information can be expressed by differently setting the color of the center part 138 and the color of the side parts 139. For example, one type of classification information (for example, casino information) can be expressed by the color of the center part 138, and the other type of the classification information (for example, junket information) can be expressed by the color of the side parts 139.

[0087] FIG. 18 is a top plan view illustrating the sheet-shaped member 110 filled with classification part members 131′ in conjunction with FIG. 6. One center part member 1381 and two side part members 1391 are filled in each blank portion 112 of the sheet-shaped member 110. The center part member 1381 and the side part member 1391 are fabricated by punching a sheet-shaped member having the same thickness as that of the sheet-shaped member 110 and a different color from that of the sheet-shaped member 110.

[0088] Alternatively, although the RFID 16 is inserted between a pair of sheet-shaped members 120 of the colored layer 12 in the aforementioned embodiment, the RFID 16 may be arranged in any place as long as it is embedded in the game token money 10. For example, the RFID 16 may be arranged between the pale color layer 11 and the colored layer 12. In this case, the colored layer 12 may include a single sheet-shaped member 120. In addition, the number of the layers of the game token money 10 may be changed more than or less than that of the aforementioned embodiment.

[0089] Although the middle layer is the colored layer 12, and the surface layer is the pale color layer 11 in the aforementioned embodiment, inversely, the middle layer may be the pale color layer 11, and the surface layer may be the colored layer 12. In this case, the colored layer 12 has the notches where the classification parts 13 are filled. Alternatively, although the transparent protection layer is provided outside of the pale color layer 11 serving as the surface layer, and a layer serving as a front face of the game token money 10 in practice is the protection layer in the aforementioned embodiment, a layer having a surface visually recognizable from the front face side of the game token money 10 in this manner is referred to as the surface layer in this application because the (printing of the) front face of the pale color layer 11 can be visually recognized by observing the front face. The surface layer may also be the outermost layer.

[0104] In the examples of FIGS. 20 to 30, the numerals 17 in the center for indicating the value information, and the marks 14 and 15 for indicating the identification information are not illustrated for simplicity purposes. However, any information equal to or different from the information of the aforementioned embodiment may also be inserted into the game token moneys of each modification.

[0105] Next, a use of the game token money 10 filled with the classification part will be described. As described above, the classification part indicates the classification information. The classification information may include, for example, any one of information for distinguishing whether the game token money 10 is a rolling chip or a cash chip, junket information differently set for each junket to specify a junket, and casino information differently set for each casino to specify the casino.

[0106] The game token money 10 is roughly classified into VIP chips and typical common chips. Note that the VIP chips are game token money available for VIP players. For example, a player who deposits money equal to or more than a predetermined amount in a casino becomes the VIP player.

[0107] Each of the VIP chips and the common chips can be classified into cash chips, rolling chips, promotion chips, and the like. The cash chips are game token money that can be exchanged with cash. The rolling chips are game token money that can be used to obtain cap chips by participating and winning in a game. In addition, the promotion chips are game token money distributed for promotion.

[0108] Here, the rolling chip will be further described. The “rolling” refers to an action for exchanging the cash chip with the rolling chip. The rolling chip can be bought by only a player who deposits a predetermined amount of money in a casino and opens a rolling program. When a player participates and wins in a game using the rolling chips, withdrawal is made on the basis of cash chips. A player can exchange cash chips (or cash) with rolling chips, and a predetermined percentage of a total rolling money amount is paid to a player as a commission whenever the rolling. Therefore, if the rolling money amount increases, the player can get the more commission depending on the rolling money. In this manner, an action of continuously exchanging (rolling) the rolling chips and the cash chips is referred to as “rolling”. The commission generated in the rolling is input to a system and is managed by the system.

[0109] Next, the junket chip will be further described. The game token money used by the junket has a mark dedicated to each junket. It would be difficult to distinguish a plurality of junkets just by using the shape and the arrangement of the classification part. In this case, similar to the examples of FIGS. 17, 29, and 30, it is advantageous to provide classification information for distinguishing the junket in combination with a plurality of colors.
