Claims

[Scope of utility model registration request]

A device body is provided with a power jack into which a plug for an AC adapter is inserted into which a DC voltage obtained from an AC adapter that step-down rectifies a commercial AC power source is inserted, and a dry battery is detachable from the device body. A battery storage container in which a storage section is formed, and a battery formed in the battery storage container, which outputs a DC voltage obtained from the dry battery, and which is inserted into the power jack when combined with the main body of the device. a positive terminal and a ground terminal that constitute the power jack and come into contact with the positive and negative terminals of the AC adapter plug or battery plug when the plug is inserted;
A switching contact piece that constitutes the power jack and is disconnected from the ground terminal when the AC adapter plug or battery plug is inserted, and a DC power source that is connected to the positive terminal of the power jack via the power switch. a load to which is supplied; a rechargeable battery housed in the device body and connected between the positive terminal and the switching contact; and a rechargeable battery connected between the switching contact and ground. A charging resistor for limiting the charging current of the rechargeable battery, connected between the switching contact piece and ground, and formed on the battery housing when the battery housing and the device main body are combined. A control device for a power supply circuit consisting of a changeover switch that is pressed and closed by a changeover protrusion.
