つた。<Prior Art> Conventionally, the above-mentioned electrical devices have been operated using dry batteries or rechargeable batteries as power sources when they are used as portable devices. In general, when the portable electric device is a magnetic recording/reproducing device, the battery power source mentioned above can only be used for a few hours because multiple motors are used and the power consumption is large, and the battery needs to be replaced. There is. At this time, since battery power is not supplied to the main body, the operation of the magnetic recording and reproducing device is temporarily stopped, making continuous recording and reproducing impossible.
〈目的〉
本考案は上記欠点を除去するものであり、主電

行なうものである。<Embodiment> An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a replaceable main battery power source consisting of a dry cell or a rechargeable battery, which supplies DC power to a magnetic recording/reproducing device 3 through two changeover switches consisting of relays 2a and 2b arranged in parallel. An auxiliary battery 7 consisting of a rechargeable battery built into the magnetic recording/reproducing device 3 is connected to the other terminal of the relays 2a and 2b, and this auxiliary battery 7 is fully charged in advance from the main battery power source 1 through a charging circuit 8. The main battery power source 1 is provided with a battery sensor 4 that detects battery consumption, prompts battery replacement with an indicator light 5, and sends a changeover signal. The changeover signal causes the relays 2a and 2b to perform a changeover operation. At this time, a delay circuit 6 is inserted in one of the relays 2b, so that the changeover operation is performed a moment later than that of the relay 2a.

ある。 Therefore, when the main battery power source 1 is exhausted, the indicator light 5 is turned on by the battery sensor 4, and the switching signal first switches the relay 2a to the auxiliary battery power source 7 side, and then the relay 2b switches to the auxiliary battery power source 7 side. The battery power source is switched to the auxiliary battery power source 7 without momentary interruption. Next, when the main battery power source 1 is replaced, the indicator light 5 is turned off by the battery sensor 4, and the relays 2a and 2b are sequentially switched to the main battery power source 1 side by a switching signal. At the same time, the auxiliary battery power source 7 is sufficiently charged from the main battery power source 1 through the charging circuit 8 in preparation for the next replacement operation.
