ABSTRACT:
A portable radio device in which a radio telephone device body and a receiver unit are separately constructed and connected together by a pair of adjustable supporting rods. As a result, the distance between the radio telephone device body and the receiver unit can be adjusted according to whether the device is being used as a telephone unit or a pager unit. While being used as a telephone, the distance between a receiver and a microphone can be easily adjusted to the distance between an ear and a mouth of a user. When the device is used as a paper, it can be miniaturized so as to be conveniently carried.
