PURPOSE:To make a body compact without constituting it as folded structure by fixing a transmitting microphone to the head part of a transmitting/receiving antenna as a united structure. CONSTITUTION:The transmitting/receiving antenna 2 has structure to be stored in the body 1. When the antenna 2 fixed to the head part of the transmitting microphone 3 as the united structure is drawn out from the body 1 at the time of transmission, a transmission-enabled state is set up and a proper interval can be set up between the microphone 7 and a receiving speaker 4. When the antenna 2 is stored in the body 1 at the time of completing the transmission, a transmission-disabled state is set up. Since the proper interval can be set up between the microphone 3 and the speaker 4, the body part can be compacted without constituting it as folded structure. |
