ABSTRACT:
A structure compliant with non-contact power transmission includes a placement member that includes a placement side, an electronic instrument including a non-contact power transmission power receiving device being placed on the placement side, a non-contact power transmission power transmitting device, and a position detection circuit that detects the positional relationship between a primary coil and a secondary coil. The power transmitting device detects the relative positional relationship between the primary coil and the secondary coil using a harmonic detection circuit, and drives an XY stage using an actuator to automatically position the primary coil with respect to the secondary coil, for example.
