摘要：
In a wireless reader/writer according to one example of the present invention, a reader/writer main body 120 emits a radio wave with a different output power from an antenna 121 when a base unit 140 is detected to be mounted on an enclosure. In addition, when a base unit 140A is detected to be mounted on the enclosure, a reader/writer main body 120A controls a switching device 132 to emit radio waves simultaneously or alternately from a first antenna and a second antenna.
