The influence of noise can be suppressed by shielding 2 and. In addition, the side wall portions 96, 9 of the mounting base body 36
Since the support shafts 100, 100 are arranged with respect to 8 in the horizontal position, the positions are rearward and upward from the center. Therefore, the rearward projecting dimension of the power supply device 32 in the horizontal position of the mounting base body 36 is small. Can be suppressed. Further, the upward projection size of the power supply device 32 in the horizontal posture can be suppressed small, and the upper space of the second cover member 30 can be effectively used (see FIG. 10A).

Next, when the game board J is replaced, for example, when a small type variable design display device of the first type is arranged at the center of the board, a large electric prize winning device is provided below the display device. Since a large cover protection space for game parts by the first cover material 28 on the upper side of the back cover member 26 is not required, a large cover protection space for game parts by the second cover material 30 is required. Becomes Therefore, in this case, by disposing the power supply device 32 in the vertical posture while the mounting base body 36 is in the vertical posture, a large cover protection space is secured on the front side of the second cover member 30. That is, by gripping the gripping pieces 74, 74 of the engaging gripping body 68 projecting rearward of the locking member 38 arranged in each of the side frame portions 53 with fingers or the like, they come close to each other, The locking protrusions 76 are formed in the through holes 6 of the support protrusions 58.
The engagement member 38 is displaced in the direction of releasing the engagement state, and the locking member 38 is moved upward along the engagement hole 56 to the release position as it is. As a result, the lower locking piece 8 of the locking member 38
5 is separated upward from the locking piece 106 of the mounting base body 36, and the base body 36 is rotatable in a direction for moving the front wall portion 92 upward (counterclockwise direction in FIG. 10).

By elastically deforming them so that they come close to each other, the locking piece 122 of the restriction portion 118 is displaced in the releasing direction for releasing the engagement with the hole 110, and in this state, the board case stopping member 112 is rotated to the release position. Thereafter, by sliding the power supply device 32 to the right (disengagement direction), the engagement piece 134 is disengaged from the engaged piece 90, and the power supply device 32 is detached from the mounting base body 36. You can As described above, the engagement between the locking piece 122 of the board case stopping member 112 and the hole 110 of the mounting base body 36 is released by the elastic deformation generated by gripping the gripping piece 119, and is therefore easy and elastically deformable. Since the portion to be engaged is large, the possibility that the locking piece 122 will be damaged by repeated fatigue is small, and the durable life is extended.

In the embodiments, the power supply board is described as an example of the board to be mounted on the mounting base body, but the present invention is not limited to this, and the target board is a firing control board or a voice control board. Other substrates such as a substrate may be used.
Further, in the embodiment, the left side wall portion which abuts the corresponding end portion of the storage box body is used as the regulation means for regulating the sliding of the storage box body mounted on the attachment base body. It is possible to adopt a configuration in which the engaging piece or the engaging piece of the housing box is provided with a wall or the like as restriction means, and the slide is restricted by the engaging piece or the engaged piece contacting the wall. Further, in the embodiment, the case where the housing box body is mounted on the separate mounting base body rotatably arranged on the back cover member has been described, but it is integrally provided on the back cover member in a non-rotatable state. The housing box may be attached to the mounting base.

Further, the retaining means is not limited to the structure for rotating between the restricting position and the releasing position, but may be a means for moving in parallel. Furthermore, the retaining means is not limited to synthetic resin, and may be thin metal or the like as long as the locking portion can be detached from the locked portion by elastic deformation. The sliding direction at the time of mounting and removing the housing box to the mounting base may be opposite to that of the embodiment or may be the vertical direction, and the retaining means is provided on the side that regulates the sliding at the time of removal.
