特徴とする電源回路。 A secondary battery that is charged by an external power source, a voltage detection circuit that detects whether the output voltage of the secondary battery is above a specified value, and a voltage detection circuit that converts the output voltage of the secondary battery that exceeds the specified value to a constant voltage below the specified value. Based on a detection signal from a constant voltage circuit that converts and outputs the voltage and the voltage detection circuit, when the output voltage of the secondary battery is equal to or higher than a specified value, the output of the secondary battery is sent to the load via the constant voltage circuit. A power supply circuit characterized in that the power supply circuit is provided with a switching means for directly supplying the output of the secondary battery to a load when the output is equal to or less than a specified value.
