Patent ID: 8373385

Claim:
A non-contact charger comprising: a casing having a recessed portion in which a cordless handset is placed; a primary coil which is provided in the casing to be opposed to the cordless handset upon placement of the cordless handset in the recessed portion of the casing; an oscillating portion which oscillates a primary coil to generate a magnetic flux energy; a detecting portion which detects at least one of a current value and a voltage value in the oscillating portion; and a controller which stops a generation of the magnetic flux energy based on the at least one of the current value and the voltage value detected by the detecting portion; wherein: the controller includes a two-reference-value-comparing portion which compares the at least one of the current value and the voltage value as a detected value detected by the detecting portion with a lower reference value and an upper reference value different from each other, and which controls the generation of the magnetic flux energy based on a first comparison of the detected value with the upper reference value and second comparison of the detected value with the lower reference value; the controller includes an oscillation-maintaining portion which controls the oscillating portion to maintain the generation of the magnetic flux energy while the detected value is not smaller than the upper reference value and the detected value is not larger than the lower reference value; and the controller is configured to stop the generation of the magnetic flux energy when the detected value is smaller than the upper reference value and the detected value is not larger than the lower reference value.
