CHARGING APPARATUS
First Claim
1. A charging apparatus that transmits electrical power to a charging target device by electromagnetic induction to charge a secondary battery of the charging target device, the charging apparatus comprising:
- a power transmission coil;
a position detection section that detects a position of a power reception coil of the charging target device placed on the charging apparatus, the position detection section includes a plurality of coils disposed separately from the power transmission coil; and
a near field communication antenna that enables near field communication with the charging target device by electromagnetic induction, whereinthe near field communication antenna is any one of the plurality of coils of the position detection section.

Abstract
A charging apparatus is provided that avoids a reduction in the strength of radio waves or a magnetic field used by a charging target device having a wireless communication function and reduces an influence on the radio waves or magnetic field. In this apparatus, position detection section (201) detects a position of power reception coil (251) of charging target device (150) placed on charging table (101). Power transmission coil (208) is made close to power reception coil (251) and transmits electric power. Coil moving mechanism (207) brings power transmission coil (208) close to the position of power reception coil (251) that is detected by position detection section (201).
