Document Type and Number:
WIPO Patent Application WO/2013/001812
Kind Code:
A1
Abstract:
This power supply device (2), which supplies electric power in a non-contact manner to a power-receiving device (4), is provided with: a substrate (46); a primary coil (48) that is positioned on the substrate (46), and generates flux by means of an alternating current; a cover (44) that is attached to the substrate (46), and covers the primary coil (48); and a motion detection means (14) that detects the motion of an object (50) on the cover (44). Since the motion detection means (14), which is capable of detecting the motion of the object (50) on the cover (44), is provided, the intrusion of the foreign object (50) between the primary coil (48) of the power supply device (2) and a secondary coil belonging to the power-receiving device (4) can be reliably detected.
