PROBLEM TO BE SOLVED: To provide a Pachinko game machine which can eliminate the missing of the receipt of commands at the time of instant power failure. SOLUTION: A main circumference serial transmission port 4100ae can maintain a state wherein a reference control voltage is applied in such a manner that even when the reference control voltage which is applied from a first power source line at the time of the occurrence of instant power failure falls, the reference control voltage from the plus terminal of an electrolytic capacitor MC2 of a main control filter circuit section 4100g is applied. Also, an interface circuit which is constituted of a transistor MTR20 and so forth can maintain a state wherein a communication control voltage is applied in such a manner that even when the transmission control voltage which is applied from a second power source line through a diode at the time of the occurrence of instant power failure falls, the transmission control voltage from the plus terminal of the electrolytic capacitor MC20 is applied. Thus, the missing of a command which is being transmitted to a peripheral control board 4140 from a main control board 4100 can be prevented from occurring. COPYRIGHT: (C)2011,JPO&INPIT |
