Since each unit is attachable to and detachable from the mechanical base, each unit can be attached and detached separately. Therefore, not only the assembly work in the factory but also the maintenance / inspection work in the game store is easy, and in the case of a failure, it can be processed in a short time by replacing the whole unit, which causes trouble to the player. Less to call.

According to the fifth aspect of the invention, a plurality of units constituting the auxiliary device are detachably attached to the rear surface side of the auxiliary device attachment wall of the mechanical base, a chute unit, and a ball discharging unit. It consists of a gutter unit, a safe unit, and a terminal unit. Therefore, the auxiliary device can be easily assembled, and the manufacturing cost can be reduced. Further, since the auxiliary device can be standardized and applied to various types of gaming machines, management of parts and the like can be facilitated and manufacturing cost can be further reduced.

According to the sixth aspect of the invention, when the tank unit is attached to the mechanical base, the earth member provided in the tank unit is electrically connected to the earth conducting portion of the mechanical base. Therefore, it is not necessary to perform the ground wiring work after the tank unit is mounted on the mechanical base, and the assembly process can be simplified. Further, since the static electricity charged on the spheres stored in the tank unit can be reliably removed, the noise caused by the static electricity is reduced, which can reduce the runaway of the computer-configured control device. it can.

In the invention according to claim 7, since the ball passage is integrally provided in the mechanical base, the number of members constituting the ball passage can be reduced. Therefore, it is possible to reduce the number of parts of the auxiliary device related to the ball passage, further facilitate the assembly of the auxiliary device, and reduce the manufacturing cost.

According to the eighth aspect of the invention, when the game machine is discarded, the fragile portion is broken, so that the member in which the inner frame, the frame and the mechanical base are integrally molded can be easily divided into a plurality of parts. Therefore, when the inner frame or the like is discarded, the size of the waste can be easily reduced, so that the disposal can be further facilitated.
