Abstract: It is an object of the present invention to enable wireless communication across a broad range while requiring a minimum of design changes. According to the present invention, a plurality of wireless data output mechanisms (LEDs) are loaded at different angles to each other into a wireless communication apparatus, and a movable shutter for selecting at least one of the LEDs is located in front of the LEDs. The shutter has an output hole that is so formed that the selection of an arbitrary LED is possible, and as the shutter is shifted to shield unnecessary LEDs, it is possible to select only a desired LED. To select all the LEDs, the shutter is moved to a position where it does not shield any of the LEDs. With this arrangement, the direction for wireless communication can be easily set and the directivity of communication can be improved without reducing the light emission output.
