<P>PROBLEM TO BE SOLVED: To provide a non-contact power feeding system capable of achieving theft prevention by restricting a place and a time in which a receiving side electronic device is used and reducing the size and weight of an electronic device without need of mounting a large capacity battery. <P>SOLUTION: A non-contact power feeding system includes a power feeding device 20 having a non-contact power transmission system that transmits power for a non-contact power feed and a first non-contact communication system that implements non-contact communication, and a power receiving device 40 having: a non-contact receiving power system that receives power transmitted from the power feeding device; the first non-contact communication system; and a second non-contact communication system which can implement the non-contact communication. The power receiving device 40 supplies the received power to a power supply circuit. Either one of the power feeding device 20 and the power receiving device 40 includes a control system that controls whether or not to consume power of the power receiving device 40 which is a secondary side based on a predetermined condition, after the power feeding device 20 and the power receiving device 40 are recognized each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
