1. A contactless charging device comprising:
- a placement plate on which a portable apparatus is placed;
a charging coil that is disposed to oppose a rear surface side of the placement plate;
a position detector that includes a position detection coil disposed on or under the placement plate, and detects the portable apparatus present on the placement plate at a predetermined time interval;
a foreign object detector that includes a foreign object detection coil disposed on or under the placement plate, and detects a conductive foreign object present on the placement plate at a predetermined time interval;
an alarm that issues a warning on the basis of detection results from the position detector and the foreign object detector; and

Abstract
A contactless charging device includes a placement plate on which a portable apparatus is placed, a charging coil, a position detector having a position detection coil, a foreign object detector having a foreign object detection coil, an alarm, and a controller. The position detection coil and the foreign object detection coil are disposed on or under the placement plate. The controller drives the alarm if the foreign object detector detects the presence of a conductive foreign object on the placement plate, and then the position detector detects the portable apparatus on the placement plate.
