PROBLEM TO BE SOLVED: To reduce burdens required for command transmission by a game control means to other control means. SOLUTION: The CPU 56 of a main substrate 31 sends out presentation control command data for instructing game presentation through an output port 571 and an output buffer circuit 63 to a general presentation substrate 90. In the general presentation substrate 90, a presentation control command from the main substrate 31 is inputted through an input buffer 88 and an input port 98 to the CPU 89 for presentation control. The presentation control command is sent out corresponding to the progress of a game executed by the CPU 56 of the main substrate 31. The CPU 89 for the presentation control prepares a display control command to a display control means and a lamp control command to a lamp control means on the basis of the received presentation control command. Also, the display control mans prepares a sound control command to a sound control means on the basis of the display control command.
