Non-contact charger
First Claim
1. A non-contact charger comprising:
- a case having a top plate having an upper surface onto which an electronic device having a secondary coil is to be placed;
a primary coil installed in the case;
a detector that is installed in the case and detects a position of the electronic device on the upper surface of the top plate of the case;
a controller capable of a start of charging of the electronic device through the primary and secondary coils when the electronic device on the upper surface of the top plate is detected by the detector; and
wherein the controller delays the start of the charging of the electronic device by a predetermined period of time when a change of the position of the electronic device is detected before elapse of a predetermined determination period of time after a placement of the electronic device onto the top plate is first detected by the detector, andwherein the predetermined determination period of time for detecting the change of the position of the electronic device is shorter than the predetermined period of time during which the charging of the electronic device is delayed.

Abstract
A non-contact charger includes a position detector, a determination unit, a primary coil, a coil moving unit, and a controller. The position detector detects placement of an electronic device, which incorporates a secondary coil, onto a top plate of the non-contact charger. The determination unit determines whether the electronic device is placed onto the top plate of the non-contact charger from a lateral direction. When the determination unit determines that the electronic device is placed onto the top plate from the lateral direction, the controller instructs the coil moving unit to wait for a predetermined period of time in moving the primary coil. After the waiting for the predetermined period of time to delay the movement of the primary coil, the controller moves the primary coil toward a position of the secondary coil of the electronic device.
