Note that the power supply process is a process performed when the power supply apparatus 100 is in a power-on state.

  In step S <b> 301, the control unit 101 determines whether there is at least one electronic device within the predetermined range 500. For example, the control unit 101 determines whether there is at least one electronic device within the predetermined range 500 according to the position information supplied from the position detection unit 106. When it is determined that at least one electronic device exists within the predetermined range 500, the control unit 101 causes the wireless communication unit 105 to acquire identification data of the electronic device that is detected to exist within the predetermined range 500. Control. Furthermore, the control unit 101 uses the identification data acquired by the wireless communication unit 105 to allow the first electronic device 200, the second electronic device 300, and the third electronic device to be wirelessly fed within a predetermined range 500. Whether at least one of 400 is present is detected. When the control unit 101 detects that at least one of the first electronic device 200, the second electronic device 300, and the third electronic device 400 exists within the predetermined range 500 (YES in S301), S302 Proceed to When the control unit 101 detects that the first electronic device 200, the second electronic device 300, and the third electronic device 400 are not present within the predetermined range 500 (NO in S301), the process again returns to S301. repeat.

For example, when the first electronic device 200, the second electronic device 300, and the third electronic device 400 exist within the predetermined range 500, the control unit 101 determines that two electronic devices exist within the predetermined range 500. It is determined that there are two or more. In addition, for example, when the third electronic device 400 does not exist within the predetermined range 500, but the first electronic device 200 and the second electronic device 300 exist, the control unit 101 falls within the predetermined range 500. It is determined that there are two or more electronic devices. Further, for example, when the second electronic device 300 and the third electronic device 400 do not exist within the predetermined range 500, but the first electronic device 200 exists, the control unit 101 falls within the predetermined range 500. It is determined that there are not two or more electronic devices.
