The game rules are programmed in advance, and the information (rank and suit) of the distributed card 1 is read, It has a structure that can determine whether the game is winning or losing. For example, in a baccarat game, a bunker win, a player win, and a tie (draw) are basically determined by the rank of each 2-3 cards, and a determination result (win / loss result) is displayed on the display lamp 13. .

The management control device 14 reads the information (rank and suit) of the card 1 obtained from the card distribution device 3 to determine the winning / losing result of each game, and the chip 120 as a game substitute currency placed by the game participant 6. The winner 6W and the loser 6L among the participants 6 in each game are determined using the measurement results of the position, type, and number of games. Further, the amount of the chip 120 as the game substitute money redeemed to the winner 6W among the participants 6 from the total amount of the balance calculation on the casino side (chip 120 as the game substitute money betted by the loser 6L) in the game table 4 A calculation function is provided for each game (the amount obtained by subtracting the total amount).

The image recording device 300, the total chip amount measuring device 302, and the management control device 14 in the present measurement system have a structure including a computer, a program, and a memory composed of one or a plurality of components.

Next, the details of the chip as a game substitute used for this measurement will be described. FIG. 3 is a front cross-sectional view of a chip 120 as a game substitute used in the present measurement system, in which a plurality of plastic layers of different colors are laminated, and at least a colored layer 121 is provided in the middle, and this intermediate coloring A multilayer structure in which a white layer 122 or a light-colored layer (not shown, but a layer lighter in color than the colored layer 121) is laminated on both sides of the layer 121. As described above, the color layer 121 is provided, and a multilayer structure in which a white layer 122 or a light color layer (not shown, but a layer having a lighter color than the color layer 121) is laminated on both sides of the intermediate color layer 121 is provided. As shown in FIG. 6, a striped pattern in the stacking direction is formed on the side surface, and the color of the colored layer 121 is changed for each type of chip 120 (10 points, 20 points, 100 points, 1000 points, etc.) as game substitute money. By changing (red, green, yellow, blue, etc.), the type of the chip 120 as a game substitute currency can be specified.

The chip 120 as a game substitute currency is a structure having a colored layer 121 and a white layer 122 or a light color layer at least in appearance so as to form an axial stripe pattern on the side surface, and the colored layer 121 serves as a game substitute currency. The type of the chip 120 can be specified. 4A and 4B are different examples, respectively, in which the colored layer 121 and the white layer 122 or the light-colored layer are formed by injection molding. First, in a molding die (not shown), FIG. The colored layer 121 is formed, and then the white layer 122 or the light-colored layer is formed by so-called two-color molding.

Further, as shown in FIG. 5, the chip 120 as a game substitute currency is printed on the surface (upper surface and lower surface) of the white layer 122 indicating the type of the chip 120 as a game substitute currency 123 (100 points or the like). Is given. As shown in FIG. 3, a transparent layer 124 is provided as the outermost layer, and each layer is thermocompression bonded to form at least a five-layer structure. Chips 120 as these game substitutes are made of a long and narrow plastic material, and the layers (colored layer 121, white layer 122, transparent layer 124) are thermocompression bonded in a long state. A state (a five-layer structure or the like) is formed, and then formed into a circular shape or a rectangular shape by a press or the like. When punching with a press, the dimensions of the die and punch of the die for punching are designed, and R processing (round corners) is applied to the end of the outermost transparent layer 124.

That is, when manufacturing the chip 120 as a game substitute coin, first, a plate-like plastic colored layer 121 and a plate-like plastic white layer 122 or a light-colored layer are laminated to form a plurality of chips. A laminated structure composed of plastic layers is formed. And a design is printed on the upper surface and lower surface of this laminated structure, and also the transparent layer 124 is provided on it. And each layer of a laminated structure and the transparent layer 124 is thermocompression-bonded, and each layer is heat-welded, and a substitute money base plate is produced. The substitute money original plate made in this way is punched out with a die to obtain a plurality of chips 120 as game substitute money having a predetermined shape. At the time of this punching process, the upper and lower corners on the outer side of the chip 120 as game substitute money are R-processed by a die.

Furthermore, the chip 120 as the game substitute money is provided with a face code made of UV ink or carbon black ink on the surface of the white layer 122 (see FIG. 5). This face code represents the authenticity of the chip 120 as a game substitute currency. When the ultraviolet ray (or infrared ray) is applied, the mark becomes visible, and the authenticity is represented by a combination of its shape and number. . FIG. 6 is a perspective view of a state in which chips 120 as game substitute coins are stacked, and a face code F is a combination of a long code FL and a short code FS. A transparent layer (printing layer) 124 is thermocompression-bonded or coated (applied) on the outermost layer so as to cover the print 123 and the face code, but this transparent layer 124 is embossed and used as a game substitute currency. The chips 120 are prevented from coming into close contact with each other. In this embodiment, an example in which a face code is printed on the surface of the white layer 122 has been described. However, either a security mark or an optical variable device (OVD) is used instead of or together with the face code. Or both may be printed.

The edge of the outermost transparent layer (printing layer) 124 on which printing 123 (100 points or the like) has been applied is subjected to R processing (R), and in the punching process of the chip 120 as gaming substitute coins, It prevents the surface from deforming and appearing on the side. Further, the chip 120 as the game substitute money has a sharp edge, and prevents the chip 120 as a hand or other game substitute money from being damaged.

As shown in FIG. 3, the colored layer 121 may be formed of a plurality of colored layers (three layers in FIG. 3). Since the plurality of colored layers (three layers in FIG. 3) are thermocompression bonded to each other, the three-layer structure is not visible as shown in FIG. 3, and FIG. 3 represents three layers for explanation. Further, a hollow B is partially provided in the middle layer of the three layers of the colored layer 121, and the RFID 125 is incorporated therein.

Note that the RFID 125 is disposed between the colored layer 121 having a flat surface and the white layer 122 having a flat surface without providing the cutout B in the colored layer 121, and the colored layer 121 and the white layer 122 are directly bonded by thermocompression bonding. By doing so, you may make it incorporate in the chip | tip 120 as game substitute money. Since at least one of the colored layer 121 and the white layer 122 is made of a heat-deformable material such as plastic, the plastic layer of the colored layer 121 and the white layer 122 sandwiching the RFID 125 is thermally deformed by thermocompression bonding. Even if the cutout B is not provided, the RFID 125 is tightly fixed between these layers.
