Abstract
A constant voltage power source circuit according to the present invention is configured to adjust electric power that is supplied to a microcomputer by a pulse width modulation control. The microcomputer is configured to output, to the constant voltage power source circuit, a continuous signal by which the constant voltage power source circuit continuously performs the pulse width modulation control, or an intermittent signal by which the constant voltage power source circuit intermittently performs the pulse width modulation control.
