1. A power-supplying device including a plurality of primary coils comprising:
- a power supply unit configured to supply power in a non-contact manner from at least one of the plurality of primary coils to at least one power-supplied device set in a power supply area of at least one of the plurality of primary coils;
a detecting unit configured to detect whether a plurality of power-supplied devices are set in the power supply area of one of the plurality of primary coils; and
a controlling unit configured to control the power supply unit to stop supplying power from the one of the plurality of primary coils on which the plurality of power-supplied devices are detected to be set, when the detecting unit detects that the plurality of power-supplied devices are set in the power supply area of the one of the plurality of primary coils.

Abstract
Even when power is to be simultaneously supplied to a plurality of power-supplied devices by using one primary coil, it is possible to properly supply power to the respective power-supplied devices. More specifically, a power-supplying device stops non-contact power supply in accordance with the detection of a plurality of power-supplied devices set in a power supply area.

5. A control method for a power-supplying device comprising a power supply unit, including a plurality of primary coils, configured to supply power in a non-contact manner from at least one of the plurality of primary coils to at least one power-supplied device set in a power supply area of at least one of the plurality of primary coils, characterized by comprising:
-
a detecting step of detecting whether a plurality of power-supplied devices are set in the power supply area of one of the plurality of primary coils; and a controlling step of controlling the power supply unit to stop supplying power from the one of the plurality of primary coils on which the plurality of power-supplied devices are detected to be set, when it is detected in the detection step that the plurality of power-supplied devices are set in the power supply area of the one of the plurality of primary coils. - View Dependent Claims (6, 7, 8, 11)

9. A power-supplying system comprising a power-supplying device and at least one power-supplied device, wherein
the power-supplying device comprises a plurality of primary coils, a power supply unit configured to supply power in a non-contact manner from at least one of the plurality of primary coils to the at least one power-supplied device set in a power supply area of at least one of the plurality of primary coils, a detecting unit configured to detect whether a plurality of power-supplied devices are set in the power supply area of one of the plurality of primary coils, and a controlling unit configured to control the power supply unit to stop supplying power from the one of the plurality of primary coils on which the plurality of power-supplied devices are detected to be set, when the detecting unit detects that the plurality of power-supplied devices are set in the power supply area of the one of the plurality of primary coils, and the at least one power-supplied device each comprises power receiving unit including a secondary coil which receives power supplied from the power supply unit when the power-supplied device is set on any of the plurality of primary coils.
