1. A mobile terminal charging device comprising:
- a support plate in which a mobile terminal placement portion is provided on a front surface side of the support plate;
a charging coil that is movably disposed in a state of opposing a rear surface side of the support plate;
a driver that can move the charging coil on the rear surface side of the support plate;
a controller that is connected to the charging coil and the driver;
a memory that is connected to the controller; and
a plurality of foreign object detection coils that are provided on the support plate and are connected to the controller,wherein the memory stores a reference resonance frequency or a reference resonance voltage of each of the plurality of foreign object detection coils for each location where the charging coil is present, andwherein the controller compares a resonance frequency or a resonance voltage of each of the plurality of foreign object detection coils with the reference resonance frequency or the reference resonance voltage corresponding to a position of the charging coil, and performs a safety operation on the basis of a comparison result.

Abstract
A controller of a mobile terminal charging device compares a resonance frequency or a resonance voltage of each of a plurality of foreign object detection coils with a reference resonance frequency or a reference resonance voltage of each foreign object detection coil, stored in a memory, corresponding to a position of a charging coil. The controller performs a safety operation on the basis of a comparison result.
