1. A power transmission apparatus comprising:
a first power transmission unit configured to perform wireless power transmission to a power receiving apparatus in a first region by using at least one of a plurality of coils; and
a second power transmission unit configured to perform wireless power transmission to a power receiving apparatus in a second region by using at least one of the plurality of coils,
wherein, while the first power transmission unit performs wireless power transmission to a first power receiving apparatus in a common region where the first region and the second region overlap, a detection of a second power receiving apparatus occurs in a region of the first region other than the common region, the first power transmission unit stops the wireless power transmission to the first power receiving apparatus and the second power transmission unit performs wireless power transmission to the first power receiving apparatus,
wherein the plurality of coils is included in at least one of the first region and the second region,
wherein a coil that is included in the common region among the plurality of coils is used for wireless power transmission to a power receiving apparatus by the first power transmission unit and the second power transmission unit,
wherein a coil that is included in the first region and not included in the common region among the plurality of coils is used for wireless power transmission to a power receiving apparatus by the first power transmission unit and is not used for wireless power transmission to a power receiving apparatus by the second power transmission unit, and
wherein a coil that is included in the second region and not included in the common region among the plurality of coils is used for wireless power transmission to a power receiving apparatus by the second power transmission unit and is not used for wireless power transmission to a power receiving apparatus by the first power transmission unit.
