PROBLEM TO BE SOLVED: To provide a game machine capable of stably performing supply of power to a rotary accessory and data communication.SOLUTION: A printed board 4202, namely one of printed boards 4202, 4205 that are built into a rotating mechanism 3303 of a rotary display device 140 and are activated by relatively rotation, includes a plurality of concentrically disposed annular electrodes (rings) 4203a-4203e for power supply and reception of a control signal. The other printed board 4205 includes brush-shaped electrodes (brushes) 4206a-4206e allowing electrical continuity with a plurality of rings while sliding by abutting on the rings in relative rotation. At least at one of an inner peripheral side and an outer peripheral side of the plurality of rings, through holes 4204a-4204e are provided. When the through holes are disposed at the opposing inner peripheral side and outer peripheral side of an adjacent ring of the rings, the through holes are disposed at positions so as not to overlap with each other in a circumferential direction.SELECTED DRAWING: Figure 41 |
