Claims (1)
ための電池と、該電池よりの電圧を昇圧する昇圧
回路と、切換スイツチとよりなり、電池の電圧が
動作電圧以下のとき切換スイツチを第１位置に切
換え、前記電池の電圧をそのまま電気機器に供給
し、電池の電圧が動作電圧以下になつたとき切換
スイツチを第２位置に切換え、前記電池の電圧を
昇圧回路で昇圧した後電気機器に供給することを
特徴とする電源回路。 It consists of an electrical device, a battery for supplying operating voltage to the electrical device, a booster circuit for boosting the voltage from the battery, and a changeover switch. position, the voltage of the battery is supplied to the electrical equipment as it is, and when the voltage of the battery falls below the operating voltage, the changeover switch is switched to the second position, and the voltage of the battery is boosted by the boost circuit, and then the voltage of the battery is supplied to the electrical equipment. A power supply circuit characterized by supplying power.
