A secondary coil for power supply that can receive non-contact power supply from the primary coil for power supply is electrically connected to an electric circuit that can be electrically connected to a power receiving circuit of the target, and the secondary coil for power supply is connected to the target Therefore, it is possible to supply the power received from the primary coil for power feeding to the secondary coil for power feeding to the power receiving circuit of the target at a position away from the target.
Moreover, since the primary coil for electric power feeding which can carry out non-contact electric power feeding to the secondary coil for electric power feeding was provided in the storage space which can store a target object, the target object is stored in the storage space and it is for power feeding in the position away from the target object. It is possible to feed the power that is contactlessly fed from the primary coil to the secondary coil for feeding to the power receiving circuit of the object.
Further, when a mark is drawn at a position where the primary coil for power supply is provided in the storage space, and the secondary coil for power supply is placed corresponding to the mark, the primary coil for power supply is not connected to the secondary coil for power supply. Since contact power can be supplied, when the object is stored in the storage space and the secondary coil for power supply separated from the object is placed corresponding to the mark, the primary coil for power supply does not contact the secondary coil for power supply. The supplied power can be supplied to the power receiving circuit of the object.

It can be placed near the primary coil.
In addition, since the secondary coil for power feeding forms the outer shape of a sphere that encloses the secondary coil for first power feeding and the secondary coil for second power feeding, the attitude of the secondary coil for power feeding is fixed. Instead, it can be placed near the primary coil for power supply in the storage space away from the object.

In addition, when a mark is drawn at a position where the primary coil for power supply of the object support structure is provided and the secondary coil for power supply is placed corresponding to the mark, the secondary coil for power supply is changed from the primary coil for power supply. Since non-contact power can be supplied to the coil, if the object is supported by the object support structure, and the secondary coil for power supply separated from the object is placed in correspondence with the mark, the power is supplied from the primary coil for power supply. The electric power fed in a non-contact manner to the secondary coil can be fed to the power receiving circuit of the object.
Moreover, when a hollow is provided at a position where the primary coil for power supply of the object support structure is provided, and the secondary coil for power supply is placed in the hollow, the secondary coil for power supply is changed from the primary coil for power supply. Since the object is supported by the object support structure and the secondary coil for power supply separated from the object is placed in the recess, the secondary coil for power supply is supplied from the primary coil for power supply. The electric power fed in a non-contact manner to the coil can be fed to the power receiving circuit of the object.
Moreover, since the first virtual plane along which the coil wire of the secondary coil for first feeding and the second virtual plane along which the coil wire of the secondary coil for second feeding are crossed are used, When the secondary coil is separated from the object and placed near the primary coil for power supply of the object support structure, the secondary coil for power supply is supplied from the primary coil for power supply to the secondary coil regardless of the posture of the secondary coil for power supply. Non-contact power can be supplied.
Further, since the secondary coil for power supply forms an outer shape having at least a part of a convex curved surface, the power supply for the storage space can be separated from the object without being attached to the posture of the secondary coil for power supply. It can be placed near the primary coil.
In addition, since the secondary coil for power feeding forms the outer shape of a sphere that encloses the secondary coil for first power feeding and the secondary coil for second power feeding, the attitude of the secondary coil for power feeding is fixed. Instead, it can be placed close to the primary coil for power supply of the object support structure away from the object.
In addition, since the signal is output when the non-contact power supply cannot be performed until the predetermined period elapses after the object is supported, forgetting to place the secondary coil for power supply or the secondary coil for power supply Can be informed that they are placed in an inappropriate place.
Therefore, an object power supply device that has a simple structure and has little energy loss and can be used easily can be provided.
