According to the third aspect of the present invention, the back mechanism board guide member is disposed on the free end side opposite to the hinge mechanism, and the guide receiving portion that slides on the back mechanism board guide member is provided on the free mechanism board free side. Since it is arranged on the end side, it is possible to reduce the resistance when guiding to the predetermined height while raising the back mechanism board.

According to the fourth aspect of the present invention, the control device mounting base is fixed to the back side of the game board so as to protrude rearward from the opening of the game board storage member. The guide receiving portion is formed at the upper edge portion of the opening of the back mechanism panel so as to slide on the back mechanism panel guide member of the control device mounting base, so that the control device mounting base is mounted. It is only necessary to perform the operation, and it is not necessary to separately attach the back mechanism panel guide member. Further, the strength of the back mechanism board guide member can be easily secured. Further, since the control device mounting base is a member that protrudes rearward through the opening of the back mechanism board, it is not necessary to separately form a through opening for passing the back mechanism board guide member in the back mechanism board. The guide receiving portion can be formed at the upper edge portion of the opening of the back mechanism panel. Therefore, it is reasonable from the viewpoint of effective use of space.

According to the fifth aspect of the present invention, the winning ball collecting cover is fixed to the back surface of the game board and protrudes rearward from the opening of the game board storing member, and the back mechanism board guiding member is provided above the winning ball collecting cover. The guide mechanism is formed at the upper edge of the opening of the back mechanism board so as to slide on the back mechanism board guide member of the winning ball collecting cover. Therefore, the back mechanism board guide member is separately attached. This saves time and facilitates formation of the guide receiving portion.
