できるように機能する。In order to attach the game board 15 to the front frame 4, first, the projection (dove) 67 of the protection cover 32 is fitted into the fitting hole (dove hole) 68 of the game board 15, and the protection cover 32 is attached. Attached to the back of the game board 15. The fitting position of the protective cover 32 is uniquely determined by the fitting of the projection (dough) 67 and the fitting hole (dough hole) 68, and the protective cover 32 is easily and securely placed at a predetermined position on the back surface of the game board 15. As a result, the abutment piece 66 of the protection cover 32 and the game board fixing member 49 are correctly positioned, and the game board 1 is prevented from falling off.
5 is held in close contact with the back surface. Next, after the game board 15 is brought into close contact with the game board mounting frame 14, the locking member 54 of the game board fixing member 49 is moved from the unlocked position of the game board 15 shown by the chain line in FIG. 11 to the fixed position shown by the solid line in FIG. By rotating, the locking portion 59 of the locking member 54 abuts on the upper surface of the abutting piece 66 of the protective cover 32 and the game board 15
Is strongly pressed against the game board mounting frame 14. Thus, the game board 15 can be securely and firmly pressed and fixed to the game board mounting frame 14, and the protection cover 32 can be easily fixed and held by the game board fixing member 49. The tapered surface 66a of the contact piece 66 functions so that the locking portion 59 of the locking member 54 can smoothly and smoothly contact the upper surface of the contact piece 66.

率を高めることができる。As is clear from the above description, the game board mounting structure of the pachinko game machine according to the present invention is as follows.
A protective piece made of synthetic resin that is detachably attached to the back side of the game board so as to cover various game parts, forms a contact piece that is in close contact with the back of the game board, and attaches the game board to the game board mounting frame In this state, the game board is pressed and fixed to the game board mounting frame by pressing the locking portion of the game board fixing member against the upper surface of the contact piece of the protective cover, so that the conventional pachinko game machine is used. It is not necessary to provide a groove for fitting the contact piece to the game board, or to attach the contact piece to the game board, thereby simplifying the manufacturing process and reducing the number of parts. And cost can be reduced. In addition, the fixing of the game board and the attachment of the protective cover can be performed in one behavior, and the work efficiency can be improved.

For example, by covering the game control circuit board (main board) for controlling the pachinko game with the protective cover, the game board is removed from the game board mounting frame and the protective cover is not removed unless the game control circuit board (main board) is removed. Because it cannot be attached or detached,
It is also possible to reliably prevent an illegal game due to replacement of the game control circuit board (main board).
