PROBLEM TO BE SOLVED: To provide a Pachinko game machine which can eliminate the missing of the receipt of commands at the time of an instant power failure.SOLUTION: A main circumference serial transmission port 4100ae is configured to be applied a reference control voltage from a plus terminal of an electrolytic capacitor in a main control filter circuit unit, even if the reference control voltage applied from a first power source line drops caused by an occurrence of an instant power failure. Also, an interface circuit comprising a transistor MTR20 and the like is configured to maintain a state where a communication control voltage is applied due to the application of the communication control voltage from the plus terminal of the electrolytic capacitor MC20, even if the communication control voltage applied from a second power source line via a diode MD20 drops caused by an occurrence of an instant power failure. |
