Turns on when low, and outputs high from the collector. At this time, the controller 24 outputs a charge permission signal. However, no current flows through the constant current circuit 10 because both ends of the constant current circuit 10 are short-circuited. When the terminal 6 and the contact 8 are opened by the connection of the AC adapter, the stabilized voltage formed by the constant voltage circuit 9 is applied to the internal battery 2 and the constant current circuit 10, and a charging permission signal is input to the constant current circuit 10 in advance. Therefore, the constant current circuit 10 is turned on. In this case the potential V S of the side of the terminal 4 of the constant current circuit 10 is low, Tr continues to turn on, the detection circuit 23 continues to output a high. Therefore, the controller 24 continues to output the charging permission signal and keeps the charging operation of the constant current circuit 10 on, so that the internal battery 2 as a secondary battery is charged.
