Claim 4:
5. A power supply system comprising:
a plurality of power reception apparatuses;
a power supply apparatus configured to supply power wirelessly to the plurality of power reception apparatuses; and
an obstruction position detection apparatus configured to:
make a detection of a position of an obstruction moving between the power supply apparatus and at least one power reception apparatus of the plurality of power reception apparatuses; and
transmit a result of the detection to the power supply apparatus as position information,

wherein the power supply apparatus comprises
a power supply antenna configured to emit, to the plurality of power reception apparatuses, a radio wave that is based on a power supply signal,
a directivity control unit configured to control directivity of the power supply antenna,
a position information acquisition unit configured to acquire the position information from the obstruction position detection apparatus, and
a control unit configured to:
based on the position information, determine a power reception apparatus, among the plurality of power reception apparatuses, to which power is to be supplied while avoiding the obstruction; and
control the directivity control unit to steer the radio wave toward the determined power reception apparatus; and
dynamically change the determined power reception apparatus as a result of detection of movement of the obstruction between the power supply antenna and the plurality of power reception apparatuses.
