Non-contact charging module and reception-side and transmission-side non-contact charging apparatuses using the same
First Claim
1. A non-contact charging module that performs power transmission by an electromagnetic induction with another non-contact charging module that comprises a first hole and that is allowed to align with the other non-contact charging module in either a first case or a second case, the first case being a case where a magnet included within the first hole in the other non-contact charging module is used when alignment with the other non-contact charging module is performed, the second case being a case where the magnet is not within the first hole and thereby not used when the alignment is performed, the non-contact charging module comprising:
- a planar coil portion in which a conducting wire is wound in a substantially rectangular shape and that comprises a second hole of a predetermined size, the second hole being provided within an inner winding of the planar coil portion; and
a magnetic sheet on which a coil surface of the planar coil portion is placed and that faces the coil surface of the planar coil portion, whereina length of a shortest distance between opposed inner sides of a substantially rectangular hollow portion of the planar coil portion is longer than a diameter of the magnet, andthe predetermined size of the second hole is greater than 15.5 mm.

Abstract
It is an object to provide a non-contact charging module that prevents the magnet from negatively influencing particularly the inside portion of a coil and improves power transmission efficiency, even when a magnet is used for alignment. This non-contact charging module is a reception-side non-contact charging module, to which power is transmitted from a transmission-side non-contact charging module which is equipped with magnet, by electromagnetic induction, in which the non-contact charging module includes a planar coil portion around which spiral electric lines are wound, and a magnetic sheet disposed to face the surface of coil of the planar coil portion so that it faces the magnet of the transmission-side contact module, in which the inner diameter of the planar coil portion is larger than the magnet.
