To realize a game machine which can deal with even increase in image data for making a symbol display means performing display.

Sub-CPU 32e receives and analyzes an image control command from a main board 100 and sends the result to VDP(video display processor) 32g. VDP 32g reads out a character corresponding to the analysis result from a character ROM 32i, calculates addresses, or the like, of dots of the character, and stores the result into a pallet RAM 32h. The VDP 32g sends out RGB signals based on the calculation result stored in the pallet RAM 32h to an LED analog board 32c. The LED analog board 32c executes color correction and brightness control of taken-in RGB signals and sends out the signals to an LED invertor board 32a. The LED invertor board 32a raises voltage of the taken-in signals and sends out the signals to a special symbol display 32b, which displays LED dots corresponding to the taken-in signals.
