By the way, in the above power supply apparatus, power is always supplied to the power supply coil, and a communication request signal is output at a constant period. When the electronic device is placed on the top plate at a position facing the power supply coil and a response signal is returned from the electronic device to the output communication request signal, power is supplied from the power supply coil.
However, in such a configuration, the power supply apparatus consumes power (standby power) in order to output the communication request signal at a constant period. Naturally, reduction of power consumption is always required.

In addition to this, the proximity sensor detects whether or not the electronic device is in a position corresponding to the power supply coil. When it is determined that the electronic device is in a position corresponding to the power supply coil, power is supplied from the power supply coil. There is also a technique.
However, even in this method, since power is consumed for operating the proximity sensor, there is sufficient room for power consumption reduction.

  An object of the present invention made there is to provide a wireless power feeder and a fixture that can reliably reduce power consumption.

The present invention employs the following means in order to solve the above problems.
That is, the present invention is a wireless power feeding apparatus that performs non-contact power feeding to an electronic device, and a power feeding unit that performs non-contact power feeding to a power receiving unit of the electronic device by supplying power from an external power source; Provided between the power source and the power supply unit, when an electronic device is set at a position facing the power supply unit, a force of a predetermined magnitude or more is applied in a predetermined direction from the electronic device.

It is preferable to cut off the electrical connection with the part.
In this way, when the electronic device does not exist at a position facing the power feeding unit, the electrical connection between the power source and the power feeding unit is interrupted, so that power consumption during standby can be reduced.

Such a switch may be of any type, but is preferably a mechanical switch that is operated by the weight of the electronic device when the electronic device is set. Thereby, standby power consumption after the switch can be made zero. In addition, since the electronic device only needs to be placed on the switch, the user does not need to perform a special operation for charging.
More specifically, the switch has a contact that can be advanced and retracted along one direction, and when the electronic device is set, the contact is pressed along the one direction by the outer surface of the electronic device. Therefore, it is preferable that the prescribed operation is performed.

In addition, power supply control that supplies power to the power supply unit when a specified operation is performed on the switch and a specified authentication process is performed with the electronic device via the power supply unit to authenticate the electronic device. It is preferable to further comprise a part.
As a result, when an article made of a conductive material other than an electronic device, such as a metal article having conductivity, is placed at a position facing the power supply unit, authentication is performed by a predetermined authentication process. There is no power supply. Therefore, wasteful power consumption can be suppressed and articles other than the electronic device to be charged can be prevented from being heated.

  In addition, the present invention can be a fixture that incorporates a wireless power feeding device as described above.

In this case, the wireless power feeding device may be provided in any part of the fixture, but is preferably provided on the top plate of the fixture.
Furthermore, it is preferable that the wireless power feeding device is accommodated in an opening formed in the top plate of the fixture.

In addition, a cover plate on which the electronic device is placed may be provided on the switch, and the surface of the cover plate may be provided so as to be flush with or below the surface of the top plate of the fixture. Thereby, even if an article larger than the cover plate is placed on the cover plate, the switch is not operated.
On the other hand, a cover plate on which an electronic device is placed may be provided on the switch, and the cover plate may be provided so that the surface of the cover plate protrudes above the surface of the top plate of the fixture. In this case, since the switch can be operated even for an electronic device larger than the cover plate, it can be charged.

The charging process was performed. Thereby, the electronic device M can be charged when necessary while reliably reducing the power consumption during standby.

  Further, in order to charge the electronic device M, it is only necessary to place the electronic device M on the cover plate 55 and to oppose the power feeding side coil 52 of the wireless power feeding device 51. This makes it easy to charge.

  Further, when the weight acts on the cover plate 55 and the switch 57 is turned on, the electronic device M is charged after a predetermined authentication process is performed between the power supply control unit 54 and the electronic device M. I did it. That is, even if an article other than the electronic device M is placed on the cover plate 55, no alternating magnetic field for charging is generated from the power supply side coil 52. Therefore, when an article other than the electronic device M is mistakenly placed on the cover plate 55, unnecessary power is prevented from being consumed, and an alternating magnetic field is applied to the article so that the article is heated. Can be prevented.
