Noncontacting charging device
First Claim
1. A noncontacting charging device for supplying, in a noncontacting state, electrical power to a storage battery of a battery-equipped radio communication device, comprising:
- a charger having a primary coil and alternating current supply means for supplying alternating current power to said primary coil;
a secondary coil that couples electromagnetically with said primary coil, and charging-power supply means for supplying, as charging power, electrical power of an induced current produced in said secondary coil to said storage battery;
halt signal generating means for generating a halt signal in response to one of an incoming call and a manual input that commands a halt of the supply of alternating current power to said primary coil; and
halting means for halting the supply of alternating current power to said primary coil in response to said halt signal;
said secondary coil, said charging power supply means, and said halt signal generating means being provided in said radio communication device.

Abstract
A non-contacting charging device is disclosed which performs charging in which electric power of a charger 1 is supplied without direct contact to a storage battery 210, and which includes in the charger 1 a primary coil 103 and circuits 104, 105 for supplying AC power to the primary coil, and also includes in the radio communication device having a storage battery 210, a secondary coil 212 that couples electromagnetically with the primary coil 103 and a circuit 211 for supplying the induced current power generated in the secondary coil to the storage battery as charging power. This device is provided with halt signal generating circuits 203, 209, and 214 for generating a halt signal that commands a halt of supply of AC power to the primary coil, and a halting circuit for halting supply of AC power to the primary coil in response to a halt signal, the halt signal generating circuit being provided in the radio communication device. If it is necessary to make or receive a call during charging of the radio communication device, a halt signal is generated on the radio communication device side to halt charging, thereby eliminating the attractive force caused by the electromagnetic induction in effect between the radio communication device and the charger, and allowing removal of the radio communication device from the charger with a minimum of effort.
