  Next, embodiments of the present invention will be described with reference to the drawings. The resin game board shown in FIGS. 1 and 2 is integrally formed by injection molding, and an opening for attaching a large board surface part (not shown) such as an electronic display or a center accessory to the surface 1 thereof. 2a, an opening 2b for attaching a variable winning opening (not shown) such as a big winning opening, and an opening 2c for attaching a winning device or a light emitting decorative body (not shown) are formed, and the inner periphery of the opening The plate-like reinforcing edges 3a to 3c are formed so as to protrude to the back side. Also, 4a to 4g are thick portions formed to be thick for driving a nail portion (not shown) such as a game nail or a windmill from the surface 1 of the resin game board, and 5a to 5g are thick portions. It is a nail hole formed in. Reference numerals 6a to 6d are mounting through holes formed at the four corners of the resin game board, and are integrally formed on the inner periphery of the through holes so that the reinforcing edges 7a to 7d protrude to the back side. Further, a reinforcing rib 8 protruding in a frame shape toward the back side is integrally formed on the outer peripheral edge of the resin game board. In addition, 10 is a handle part which is notched in a part of the reinforcing rib 8 so that it can be easily handled during carrying.

  Then, a stepped recess 9 is formed in the outer peripheral edge of the surface of the resin game board in a step shape, and when the resin game boards are stacked as shown in FIGS. The top ends of the reinforcing ribs 8 of the upper resin game board are loosely fitted into the stepped recesses 9 of the lower resin game board, and the reinforcing edges 3a to 3a of the upper resin game board in the loose fit state. 3c, 7a-7d and thick part 4a-4g are projected lengths to the back side of the reinforcing edges 3a-3c, 7a-7d and thick part 4a-4g so that the surface 1 of the lower resin game board is separated Is set.

Thus, in the resin game board according to the present invention, when stacked, the tips of the reinforcing ribs 8 and the stepped recesses 9 match the shape of a stamp, so there is no need for a separate jig. It is always stably stacked, and there is no risk of collapse even if stacked in multiple stages. For this reason, the game board can be stored in a space-saving manner and can be easily transferred. Further, since the reinforcing edges 3a to 3c, 7a to 7d and the thick portions 4a to 4g do not contact the surface of the lower resin game board at the time of stacking, there is no possibility of scratching the game board surface even if they are laterally displaced. . For this reason, generation | occurrence | production of inferior goods is suppressed.
Since the resin game board according to the present invention is subjected to surface treatment such as offset printing, film transfer, cell sheet adhesion, and hard coat layer formation after the injection molding as described above. The surface is made flush with the surface so that the surface treatment can be performed without any problem.

In this embodiment, the reinforcing ribs 8 and the stepped recesses 9 are formed on the entire outer peripheral edge of the resin game board, but these may not be the entire outer periphery but may be formed partially. In such a case, it is desirable to provide at least a balance in the vertical and horizontal directions.
Further, in this embodiment, an example in which the back side of the resin game board is stacked is shown, but it goes without saying that the stacking may be performed with the back side facing up.

  In this embodiment, the thick portions 4a to 4g are formed in a straight line so that the plurality of nail holes 5a to 5g are continuous. However, the thick portion regions for driving the nail portions are independent bosses one by one. It may be formed in a flat shape, a flat surface having a fixed area where a large number of pieces can be driven together, or the entire surface area of the game board may be formed thick. FIG. 5 shows a resin game board in which the entire surface area is formed thick as described above. By forming the entire surface area in this way thickly, the reinforcing edges 3a to 3c and 7a to 7 shown in the above embodiment are used. 7d or the like may be unnecessary, and in this case, the protruding length of the thick portion 4 to the back side so that the thick portion 4 is separated from the surface of the lower resin game board in the stacked state. Should be set.

  In general, since the nail holes have a small inner diameter and are provided in large numbers, it is assumed that it is difficult to form them by injection molding. You may make it form a nail hole with a processing machine. In that case, it is conceivable to form a recess at the nail hole formation scheduled position at the time of molding so that the drilling tool can be easily guided during post-processing.
