Abstract

PURPOSE:To drive a plunger completely at all times while preventing flowing through a driving-voltage applying circuit for the plunger of unnecessary currents by detecting voltage applied to the plunger and interrupting driving voltage applied to the plunger when the time when the voltage is applied reaches a fixed time. CONSTITUTION:A microprocessor 4 is supplied with the potential of a node N detected by a voltage detector 3 through a terminal T2. Holding at ground potential only for a fixed time of the potential of the mode N detected by the voltage detector 3, applying only for a fixed time of high voltage+B to a plunger 1, is discriminated by the voltage detector 3. When the microprocessor 4 discriminates applying only for a fixed time of high voltage+B to the plunger 1, a pulse signal output from a terminal T1 for the microprocessor 4 is changed to a low level, and driving voltage applied to the plunger 1 is interrupted.
