PROBLEM TO BE SOLVED: To prevent the operation stop of a power circuit caused by a drop in a battery output voltage due to a rush current or the like even if a battery or the like having a large internal resistance is connected. SOLUTION: The power circuit comprises a switch section for connecting or disconnecting a power supply to or from a circuit, a stabilization section for stabilizing fluctuation in an input voltage, a booster section for boosting the input voltage, a switching section for controlling booster operation, a rectifier section for rectifying a switching waveform, a filtering section for filtering the rectified waveform, and a control section for constantly controlling the output voltage. The operation start of the power circuit is delayed from the supply start of a power supply. |
