  The holding member 87 that holds the transparent plates 85, 86 is provided with a protruding portion 93 that protrudes outward from the outer peripheral holding portion 87 b corresponding to the front transparent plate 85. The projecting portion 93 has a bent portion 93 a that is bent to the outside of the inner bent portion 61 b of the longitudinal reinforcing member 61, and has a bent portion 93 b that is bent to the upper end portion of the harness passage 96 on the lower side. The fraud prevention unit 89 includes a transparent plate 85 and a protruding portion 93. Other configurations are the same as those of the first embodiment.

  In this way, it is possible to cover the speaker housing portion 69 from the rear side with the fraud prevention portion 89 of the transparent plate unit 43. In this case, the back cover 71 in the case of the first embodiment can be omitted.

  12 and 13 illustrate a third embodiment of the present invention. The transparent plate unit 43 of this embodiment is provided with a fraud prevention unit 89 on the rear side corresponding to the left and right intermediate speakers 45A and 45B, and the fraud prevention unit 89 covers the rear side of the speaker housing 69. It is like that. The fraud prevention unit 89 may be either the first embodiment or the second embodiment. Other configurations are the same as those in the first embodiment or the second embodiment.

  In this manner, by providing the transparent plate unit 43 with the fraud prevention unit 89 corresponding to the left and right intermediate speakers 45A and 45B, the same fraud prevention measures can be taken for the intermediate speakers 45A and 45B.

  In addition, there are engaging protrusions 83a that protrude from the synthetic resin holding member 87 on the lower side of the transparent plate unit 43, and protrusions 93 at the left and right corners, respectively. Even when the transparent plate unit 43 is placed on the floor or the like, the engaging projections 83a and the projections 93 come into contact with the floor and the like, and are placed on the floor or the like by the engagement projections 83a and the projections 93. The impact at the time can be alleviated and the handling of the transparent plate unit 43 can be facilitated.

  FIG. 14 illustrates a fourth embodiment of the present invention. In this embodiment, the fraud prevention portion 89 of the transparent plate unit 43 is configured by a front transparent plate 85 and a protruding portion 93 that is detachably attached to the holding member 87.

  The two transparent plates 85 and 86 before and after the transparent plate unit 43 have substantially the same shape, and a part thereof corresponds to the rear side of the speaker housing portion 69 and the intermediate speaker 45B. The protruding portion 93 has a shape that covers the speaker housing 69 from the rear side outside the holding member 87, and is detachably attached to the holding member 87 via the mounting portion 94. The mounting portion 94 can be inserted between the front and rear outer peripheral holding portions 87b and 87c on the rear side of the abutting portion 94a and the arc-shaped abutting portion 94a that contacts the outer peripheral holding portion 87b on the front side of the holding member 87 from the outer peripheral side. And an engagement portion 94c formed on the front side of the contact portion 94a and detachably engaged with the outer peripheral holding portion 87b on the front side. The protruding portion 93 has a closing portion 93 c that enters the speaker housing portion 69. An intrusion prevention plate such as an iron plate may be provided on the front surface of the protruding portion 93. Other configurations are the same as those in the first to third embodiments.

  As described above, the fraud prevention unit 89 can be configured by a part of the transparent plate 85 of the transparent plate unit 43 and the protruding portion 93 detachably attached to the transparent plate unit 43. In particular, when the transparent plate unit 43 is a general-purpose component that can be used for a plurality of types of models having different game area 22 sizes and outer peripheral shapes, the intermediate speakers 45A and 45B are separated from the transparent plate unit 43. Providing the protruding portion 93 having a shape corresponding to the position has an advantage that it can be easily adapted to each model.

  As mentioned above, although each embodiment of this invention was explained in full detail, this invention is not limited to this each embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in each embodiment, a pachinko machine, which is one of the ball game machines, is exemplified as a gaming machine, but it can be similarly applied to a gaming machine such as an arrangement ball machine other than the pachinko machine. Not too long.

  In each embodiment, the case where the transparent plate unit 43 is provided with the fraud prevention portion 89 corresponding to the intermediate speaker 45B on the opposite side of the guide rail 23 has been mainly described. However, the embodiment corresponds to the upper speakers 44A and 44B. The fraud prevention unit 89 may be provided in the transparent plate unit 43, or the fraud prevention unit 89 may be provided in the transparent plate unit 43 corresponding to the upper speakers 44A and 44B and the intermediate speakers 45A and 45B.

  The fraud prevention part 89 of the transparent plate unit 43 may correspond to at least a part of the rear side of the intermediate speaker 45B. In that case, it is desirable that the fraud prevention part 89 of the transparent plate unit 43 corresponds to the side close to the game area 22 of the intermediate speaker 45B.

  In general, it is sufficient for the fraud prevention unit 89 to be able to prevent the illegal member inserted from the intermediate speaker 45B side from entering the rear side. However, depending on the relative relationship between the intermediate speaker 45B and the peripheral wall portion 70, it is conceivable that an unauthorized member is inserted through the peripheral portion of the intermediate speaker 45B. Accordingly, the fraud prevention unit 89 can not only prevent the fraudulent member inserted through the intermediate speaker 45B or the fraudulent member inserted through the peripheral portion of the intermediate speaker 45B, but also insert through the intermediate speaker 45B and its peripheral portion. It would be desirable to be able to prevent fraudulent members that are used.

  The fraud prevention part 89 may be entirely or substantially entirely constituted by the transparent plates 85 and 86 of the transparent plate unit 43, or may be partially constituted by the transparent plates 85 and 86 of the transparent plate unit 43. It is desirable that at least the main part is composed of transparent plates 85 and 86. The transparent plates 85 and 86 of the transparent plate unit 43 may be one.

  The intermediate speaker 45B may be inserted into the speaker housing 69 from the front side and fixed with screws or the like from the front side. Further, the speaker accommodating portion 69 may be structured to accommodate at least the rear side of the intermediate speaker 45B.
