The movable hinge 21 is prevented from moving in the up-down direction by press-fitting or screwing into the hole.

In the process in which the movable hinge 21 is half-opened to the fixed hinge 20 in the front and lateral direction by manual operation, the pin 51 is moved to the pin receiving hole 52 before the vertical wall 39 collides with the fixed blindfold 26. , The fall prevention mechanism 50 can have a role of regulating the rotational movement range of the movable hinge 21 (the rotational movement range of the movable panel frame 6). The stop structure for restricting the opening of the movable hinge 21 by the fall prevention mechanism 50 has a greater distance from the rotation center P than the stop structure by the vertical wall 39 and the fixed blind portion 26. The load applied to the fitting portion between the hinge 37 and the hinge receiving portion 23 is small.

The pin 51 may be formed on the movable back portion 36 so as to be located on the right side of the vertical wall 39. In this case, the movable side panel frame 6 is opened, and the pin 51 is removed from the movable back portion 36. An unauthorized operation member can be pryed from between the fixed blindfold 26 and the movable blindfold 38 and inserted into the gaming machine frame 1 from the hole through which the pin 51 has passed through the pin receiving hole 52. There is. On the other hand, as shown in FIG. 5, since the hinge projection 37, the vertical wall 39, and the movable back part 36 form a dead end, this dead end avoids the operation of removing the pin 51 from the movable back part 36, and prevents the illegal operation. The member is a fixed blindfold 26
Even if it is pryed from between the movable blindfold portion 38 and the movable blindfold portion 38, the dead end properly prevents the unauthorized operation member from entering the inside of the gaming machine frame 1. In order to reduce the weight, the hinge projection 37 and the vertical wall 39 are used.
Even if notches are provided in one or both of the
2 and the fixed back part 24 and the movable back part 36 form a different blind lane from the above, so that the unauthorized operation member
Even if it is inserted into the interior of the decorative hinge device 7 via the notch from between the movable blindfold portion 38, such another dead end prevents the illegal operation member from entering the inside of the gaming machine frame 1. Since these dead ends prevent fraud, the gap formed between the fixed blindfold 26 and the movable blindfold 38 when the movable side panel frame 6 is closed can enter the unauthorized operation member. The size may be sufficient.

The fall prevention mechanism 50 includes a pin 51 and a pin receiving hole 5.
Although not shown in the figure, a lower end support for supporting the lower end of the movable hinge 21 is provided at the lower end of the fixed hinge 20, or the upper end of the movable hinge 21 is provided at the lower end of the fixed hinge 20. It is also possible to adopt a structure in which an upper end receiving member supported by the upper end of the fixed side hinge 20 is provided. Also in this case, the lower end stopper and the movable side hinge 21 are mutually connected, or
It is also possible to provide a stop structure for restricting the rotational movement range of the movable hinge 21 between the upper end receiving member and the fixed hinge 20.
