前記入力電力を前記本体部に出力して電力が不足する場合、前記二次電池に充電された電力を前記入力電力に加算して、又は前記入力電力を前記二次電池に充電された電力に切り換えて、前記本体部に電力を供給する
ことを特徴とする電源回路。In the power supply circuit that supplies power to the main unit,
A secondary battery,
Charging means for charging the secondary battery with input power;
Output control means for supplying power to the main body by adding the power charged in the secondary battery to the input power or switching between the input power and the power charged in the secondary battery;
Control means for controlling the operation of the charging means and the output control means,
By control by the control means,
When there is a margin in the input power by outputting the input power to the main body, the input power is output to the main body, and the secondary battery is charged with the excess input power,
When the input power is output to the main body and power is insufficient, the power charged in the secondary battery is added to the input power, or the input power is converted into power charged in the secondary battery. A power supply circuit that switches and supplies power to the main body.
ことを特徴とする請求項１に記載の電源回路。The power supply circuit according to claim 1.
