)項記載の充電回路。[Claims for Utility Model Registration] (1) In a charging circuit that charges a memory backup battery built in a device that uses two types of power sources with different output voltages, the two types of power sources are dry batteries and AC. In addition to the adapter, a current circuit for charging from a dry cell battery that is a first power source to the battery, and a current circuit for charging from an AC adapter output that is a second power source to the battery are separately provided. A charging circuit characterized in that at least a current circuit corresponding to a power supply with a low output voltage is provided with a diode forward biased with respect to the power supply, and each current circuit is provided with a resistor for adjusting charging current. (2) A connector with a switch is attached to the device to insert the jack of the AC adapter, and when the jack is not inserted, power from the dry battery is supplied to the device body through the connector, and when the jack is inserted, In the case where the power from the AC adapter is input to the main body of the device through the connector, the utility model registration claim No. 1
Charging circuit described in ).
