Abstract: PURPOSE: To attain the radio communication of a wide range with a minimum design change. CONSTITUTION: A plurality of radio data output mechanisms (LED) 20, 22 and 24 are loaded on a radio communication equipment with mutually different angles. For selecting at least one LED, a movable shutter 14 is provided in front of LED. An output hole for selecting arbitrary LED is provided for the shutter, the shutter is moved and unnecessary LED is shielded. Thus, only desired LED can be selected. For selecting all LED, the shutter is moved to a position where all LED are not shielded. Thus, the communication direction of radio communication can easily be set and the directivity of communication improves without deteriorating light-emitting output.
