MOTOR VOLTAGE SETTING METHOD FOR PACHINKO SHOOTING MACHINE DRIVER DEVICE

摘要

PROBLEM TO BE SOLVED: To perform a constant ball shooting by inputting a variable partial voltage divided by a variable resistor within a handle to the positive input of an operational amplifier, and judging the magnitude of the variable partial voltage by a judgment circuit. SOLUTION: This motor voltage setting method for pachinko shooting machine driver device comprises inputting the variable partial voltage 3 from the variable resistor 8 to the positive input 4a of the operational amplifier 4, inputting a second partial voltage 20 on the output side of a switch circuit 5 to the negative input 4b of the operational amplifier 4, and judging the variable partial voltage 3 by the judgment circuit 21 to control the operation of the switch circuit 5.
