<p><P>PROBLEM TO BE SOLVED: To provide a non-contact power supply system which decreases a weight of a non-contact power receiving device by eliminating the need of laying feeding line almost all over a carrying passage, and prevents increase in a number of pick-up cores accompanied with increase in a number of non-contact power receiving devices. <P>SOLUTION: Air-core coils 11, 11... are installed on a carried element carried along the carrying passage, and cores 22, 22... around which coils 21, 21... are wound are installed in a power supplying section S provided at a part of the carrying passage. In the power supplying section S, the air-core coils 11, 11... receive power from the coils 21, 21... by inductive coupling and supply the power to a load. The coils 21 and the cores 22 are not installed in the carrying passage outside of the power supplying section S. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
