<p>PROBLEM TO BE SOLVED: To provide a Pachinko game machine capable of eliminating missing of a command reception in an instantaneous interruption.SOLUTION: Even when the instantaneous interruption occurs and a reference control voltage applied from a first power supply line is decreased, the reference control voltage from a positive terminal of an electrolytic capacitor MC2 of a main control filter circuit part 4100g is applied to a main-peripheral serial transmission port 4100ae, so that the main-peripheral serial transmission port 4100ae can retain such a state that the reference control voltage is applied thereto. Even when the instantaneous interruption occurs and a communication control voltage applied from a second power supply line via a diode is decreased, a communication control voltage from a positive terminal of the electrolytic capacitor MC20 is applied to an interface circuit comprising a transistor MTR20 and the like, so that the interface circuit can retain such a state that the communication control voltage is applied thereto. This configuration can prevent the missing of a command during transmission from a main control board 4100 to a peripheral control board 4140.</p> |
