PROBLEM TO BE SOLVED: To provide a game machine in which a circuit structure has no waste, and a powerful image performance can be executed stably, even under a noise environment.SOLUTION: An image control part 23 for executing an image performance comprises: a one-chip microcomputer 60 for generally controlling the image performance; a VDP 62 for generating pieces of image data of performance images of a first group and performance images of a second group, based on an instruction from the one-chip microcomputer 60; a main display device DS1 for displaying the performance images of the first group at a first gradient; and a sub display device DS2 for displaying the performance images of the second group at a second gradient. The pieces of image data for specifying the performance images of the second group are transmitted to a connection substrate 90 from the VDP 62 by four pairs of differential signal lines, then converted into a parallel format and supplied to the sub display device DS2.SELECTED DRAWING: Figure 5 |
