That is, the main board case 66 and the display board case 62 and the production board case 64 constituting the sub board case are arranged in a stacked manner in the front-rear direction at a position away from the image display means 14 and are collected by the fixing means 74. Since it is fixed, the image display means 14 can be arranged as far back as possible from the game board 11 while keeping the overall longitudinal dimension small as compared with the prior art. For this reason, even when a movable effect means or the like is arranged between the game board 11 and the image display means 14, a large space between the game board 11 and the image display means 14 can be secured, and a large movable effect means or the like can be easily obtained. Can be arranged.

  Further, since the dimension from the game board 11 to the rear surface of the main board case 66 at the rearmost part is substantially the same as the dimension from the game board 11 to the back surface of the image display means 14, the image display means 14 and the main board case 66 are moved back and forth. It becomes possible to arrange at the rear part within the allowable dimension in the direction, and the allowable dimension in the front-rear direction can be utilized to the maximum.

  In addition, a back cover 25 is provided below the support frame 22 on which the image display means 14 is mounted to cover the special symbol starting means 16, the big winning means 17, and the normal winning means 18, and the back surfaces of the back cover 25 are the substrate cases 62 and 64. , 66, the projection amount of the back cover 25 is reduced while the projection amount of the upper half 30 of the support frame 22 is increased. It is easy to match the dimensions up to the rear end with the stacked dimensions of the substrate cases 62, 64, 66.

  The case attaching portion 60 has an surrounding wall 73 projecting rearward from the rear wall portion 71 of the back cover 25 on the outer periphery thereof, and each of the substrate cases 62, 64, 66 is detachably fitted into the surrounding wall 73 from the back side. Therefore, the substrate cases 62, 64, and 66 are all better than the exposed state, and not only can the harnesses or the like be entangled with the substrate cases 62, 64, and 66, but also the substrate cases 62, The individual substrate cases 62, 64, 66 are not accidentally dropped when the 64, 66 is attached or detached.
