When the output plug is inserted into the external power jack 4, the second switch means 31, which is turned on, and the ripple filter 5 are provided. The external power jack 4 is provided with an input contact 4P connected to the plug when the output plug is inserted. The built-in battery 3 is connected to the power supply line of the main body circuit 1 via the first switch means 4A and 4B. The input contact 4P of the external power jack 4 is connected to the power line of the main body circuit 1 through a series circuit of the second switch means 31 and the ripple filter 5.
