  Moreover, since a part of the seat member 4 (second seat bent portion 33) is sandwiched between the game board base 2 and the center accessory PC, the game board members 3A to 3A to be assembled to the game board base 2 are also included. Since a part of the seat member 4 (a part of the seat main body 30) can be sandwiched between the game board member other than 3C and the game board base 2, the game board base 2, the game board members 3A to 3C And the integrity of the sheet member 4 can be further enhanced.

  The game board base 2 and the game board members 3A to 3C are first and second closely attached to the game board base 2 and the game board members 3A to 3C by performing a three-dimensional laminate decorative molding using a rectangular sheet material. The sheet member 4 having the sheet main body portions 30a and 30b, the sheet folding portion 31, and the first to fourth sheet bent portions 32 to 35 can be easily and reliably formed.

  Thereafter, the sheet member 4 is subjected to router processing. In particular, since the sheet folding portion 31 is a portion that is not exposed to the outside, strict router processing (cutting processing) is not required for the sheet folding portion 31. And, since the router processing for the sheet folding portion 31 occupies a relatively large part of the entire router processing, the processing load is reduced, the seat member 4 can be easily and reliably processed, and the productivity of the game board 1 can be increased. Can be increased.

  The game board member 3A has projections 21A1, 21A2, and 21A3 protruding rearward at the rear part thereof, and the game board base 2 includes an attachment recess 11A having the game board member 3A fitted therein and having a rear end wall 12A. Since the through-hole portions 12A1, 12A2, and 12A3 are formed on the rear end wall 12A and into which the convex portions 21A1, 21A2, and 21A3 of the game board member 3A are fitted, the game board member 3A is stably attached to the game board base 2. The thickness of the game board 1 can be maintained substantially at the thickness of the conventional game board (19 mm), and the thickness of the game board member 3A can be secured by the thickness of the game board 1 as well. .

  In other words, the thickness of the game board member 3A can be set to a sufficient thickness so that there is no problem in inserting the obstacle nail PN into the game board member 3A in a press-fit manner. It is possible to suppress the problem of bending or falling off as a whole under impact. Note that the game board members 2B and 2C and the mounting recesses 11B and 11C corresponding to the game board members 2B and 2C have the same configuration as described above and have the same effect as described above.

  The front end surface of the inner peripheral wall 14 of the game board base 2 and the front surface of the game board members 3A to 3C are stepped so that the former is located behind the latter. By molding, the sheet member 4 can be molded so that the inner peripheral edges of the game board members 3A to 3C are clearly shaped. Then, the outer peripheral portion of the center accessory PC can be satisfactorily attached to the front end surface of the inner peripheral wall 14 forming the step.

  In addition, various modifications can be added without departing from the scope of the present invention. For example, the number, shape, size, and the like of the game board member and the mounting recesses formed in the game board base can be appropriately changed due to the configuration of the game board. In this case, when the game board base is injection-molded, various insert molds are detachably set in a common mold body so that it can be formed on various game board bases, thereby reducing the equipment cost for manufacturing the game board. Can be reduced.

  Moreover, in the said Example, although the decoration image (cell image) was printed on the sheet | seat member 4, the cell by which the decoration image was drawn separately on the front of the game board base 2 and the game board members 3A-3C without doing so. An image sheet may be provided. In this case, in a state where the cell drawing sheet is set on the front surface of the game board base 2 and the game board members 3A to 3C, the three-dimensional laminate decorative molding is performed, and the cell drawing sheet is made up of the game board base 2 and the game board member 3A. -3C and the transparent sheet member 4 are sandwiched and assembled.

  In addition, the seat member 4 is provided with a sheet folding portion that closely adheres to the outer peripheral surface that forms the contour of the game board base 2 over the entire circumference, that is, the contour of the game board base 2 together with the sheet folding portion 31. You may provide the sheet folding part closely_contact | adhered to all the surrounding surface parts which form. Further, the sheet member 4 may be provided with a sheet folding portion that is in close contact with the inner surfaces of the grooves 15 and 16 and the holes 16, 17, and 18 formed in the game board base 2 and the game board members 3 </ b> A to 3 </ b> C.

  It should be noted that the present invention can be applied to game boards equipped in various game machines (pachinko game machines) and manufacturing methods thereof.
