ABSTRACT:
Since means (control terminal a 16, control terminal b 17, control terminal c 18 and voltage detection terminal 22) for controlling portable electronic apparatus charger 2 directly from CPU 13 in the inside of portable electronic apparatus body 1 is provided, the circuit scale is reduced. Further, since means (power supply detection circuit 6, switch a 7, switch b 8 and regulator a 9) for supplying an electric current to CPU 13 to allow CPU 13 to operate with a signal from sub clock 11 even when the power supply to portable electronic apparatus body 1 is in an off state is provided, if portable electronic apparatus body 1 is connected to portable electronic apparatus charger 2, then CPU 13 and only a limited number of the other circuits in the inside of portable electronic apparatus body 1 are allowed to operate as a control circuit for portable electronic apparatus charger 2.
