Abstract

PROBLEM TO BE SOLVED: To reduce a charging time by applying off-control to a power supply circuit when a secondary battery is charged so as to improve the charging efficiency of the secondary battery. SOLUTION: When a cordless telephone slave set 10 is set on a charging base 17, a charger detection circuit 18 detects connection of a charging circuit 16 to a charger 17A by detecting an output voltage or the like of the charger 17A and then the charger detection circuit 18 outputs a control signal 18a to a power supply circuit 14. The power supply circuit 14 receiving the control signal 18a inhibits supply of power to a control section 11, a radio section 12 and a base band section 13. Thus the power obtained from the charger 17A through the charging circuit 16 is supplied only to the secondary battery 15.
