ABSTRACT:
When main power is turned on by a switch SW, a pulse shaper12feeds a pulse signal having a pulse width Tp through an OR circuit14to a power supply circuit2ato turn it on. Moreover, a delay generator13agives the pulse signal a delay and then feeds it to a control signal generator15aso that a microcomputer3is turned on with a delay corresponding to the length of time required by the power supply circuit2ato start up.
