And the main body frame 44 can be held in a joined state.

Using the pachinko machine 10 having the above-described configuration, the amount of electrostatic charge of the back panel 48 during a game was measured. The amount of electrostatic charge of the backpack during the game of the conventional game machine (about 10 KVA) Was about 1/4. As described above, in the pachinko machine 10 of the present embodiment, since almost the entire back plate 48 is made of conductive plastic, the back plate 4
The static electricity generated in 8 is quickly released into the air from almost the entire surface of the back plate 48. For this reason, the charge amount of the back plate 48 is extremely low, and static electricity is prevented from adversely affecting the main control board 126 and the like. Also, there is no need to attach special discharging means.

Further, at least three surfaces of the wiring pits 106 provided on a part of the back panel 48 are conductive, so that the electric wiring accommodated in the wiring pits 106 is electromagnetically shielded. . Therefore, intrusion of electromagnetic waves from inside and outside of the pachinko machine 10 into these electric wires is prevented. For this reason, it is possible to prevent accidents such as malfunction of the main control board 126 due to noise that has entered through the electric wiring, and to improve the performance of protection against illegal acts using a radio wave transmitter or the like.
