To provide a game machine capable of stably executing powerful performance operation by suppressing noise generation and unwanted power consumption.

An image control part 23 includes: a one-chip microcomputer 60 controlling an image performance; a VDP 62 generating image data of a performance image based on an instruction from the one-chip microcomputer 60; and a liquid crystal display device DS1 displaying a performance image by receiving the image data generated by the VDP 62. The one-chip microcomputer 60, the VDP 62, and the display device DS1 are operated by a supply voltage of 3.3 V, and the liquid crystal display device is operated by a backlight part including a group of LED lamps driven by the same supply voltage to emit light.
