<p>An object of the present invention is to reduce electric power consumption of a charger as much as possible when charging is not performed. A constant voltage power source circuit (50) according to the present invention is configured to adjust electric power that is supplied to a microcomputer (28) by a pulse width modulation control. The microcomputer (28) is configured to output, to the constant voltage power source circuit (50), a continuous signal by which the constant voltage power source circuit (50) continuously performs the pulse width modulation control, or an intermittent signal by which the constant voltage power source circuit (50) intermittently performs the pulse width modulation control.</p> |
