PROBLEM TO BE SOLVED: To realize a game machine having no possibility that a player and a game parlor may suffer from an accidental disadvantage by noise or a foul play. SOLUTION: A main control substrate 100 is connected to a payment control substrate 200 through an optical fiber cable L1, and the payment control substrate 200 is connected to a pattern control substrate 32 through an optical fiber cable L2. The pattern control substrate 32 is connected to an LED (light emitting diode) control substrate 300 through an optical fiber cable L3, and the LED control substrate 300 is connected to a sound effect control substrate 79 through an optical fiber cable L4. The main control substrate 100 sends an optical control command to the respective control substrates, and the respective substrates perform presentation according to the optical control command received. Since a communication medium is light, bit transformation by invasion of noise, a foul play by connection of a suspended substrate, or the like, can be prevented. COPYRIGHT: (C)2004,JPO
