<p>PROBLEM TO BE SOLVED: To provide a radio terminal enabling a user to easily observe an optical display by illuminating an antenna top so as to light it up with light from a light source emitted at the incoming of a signal. SOLUTION: A holder 13 for guiding/holding an expansion antenna 10 is mounted on a circuit board 3 stored in a casing 2. A light emitting diode 20 to be a light source is arranged on a cylindrical boss part 2A formed on the casing 2 so as to oppose to an antenna top 12. When the diode 20 is connected to the circuit board 3, a high frequency signal received by the antenna 10 is received by a radio part and a control part outputs a lighting command signal based on the received signal, the diode 20 emits light at the incoming of a signal. When diode 20 emits light at the incoming of a signal in the stored state of the antenna 10, the antenna top 12 formed by a transparent or translucent material is illuminated by the diode 20 and lighted up.</p> |
