Abstract

PURPOSE: To repeatedly take protective actions without requiring part replacement such as fuse replacement by generating an overvoltage detection signal from an overvoltage detecting circuit when an overvoltage occurs, opening a power feed path, and interrupting the power voltage signal from a pachinko machine. CONSTITUTION: When the normal power voltage is applied to a terminal 1, a Zener diode 46 does not conduct, a transistor 35 does not conduct, and no current flows in its collector. A transistor 56 conducts due to the potential difference between an emitter and a base, a thyristor 55 conducts, and power is fed to an electric part 41. When an overvoltage is applied to the terminal 1, the Zener diode 46 conducts, a transistor 47 conducts, and a current flows in its collector. Even when the charges/discharges of capacitors 62, 63 are completed at the time of power-on, the base of the transistor 56 is kept at a high potential, the conduction of the transistor 56 is continuously blocked, the power feed line is not closed by the thyristor 55, and no overvoltage is applied to the electric part 41.
