Abstract

PURPOSE: To prevent malfunction by a method wherein a switching circuit is provided for a power source line in order to allow the power source line to turn-on after the operation of a pulse generator is stabilized.
CONSTITUTION: On turning-on a power source, the voltage applied from a rectifier 1 may increase gradually to develop a rated voltage. Then, the power source voltage of a pulse generator 3 is controlled so as to develop a rated voltage with a low voltage stabilizing circuit 2. On the other hand, whenever the threshold voltage of a detector 4 is rated higher than the voltage of the pulse generator 3, the voltage of the pulse generator 3 may be stabilized, a switching citcuit 5 which supplies the power source to a load 6 may be turned-on after developing a normal operation to prevent completely the malfunction. Further, on turning-off the power source, the voltage of the rectifier 1 is gradually dropped to appear lower than the threshold voltage, which turns-off the switching circuit 5 to prevent from malfunction.
