Abstract
Abstract A portable telephone with a fundamental structure consisting of a first housing with a built-in receiver and a second housing with a built-in transmitter which are connected around a hinge section in a rotatable manner, which further has biasing means for biasing the first housing and the second housing for their unfolding, attaching means for attaching the first housing and the second housing and detaching means for detaching the attached housings. An antenna is attached to the second housing in a rotatable manner. The first housing and the second housing are folded when the telephone is not in use. For reception or transmission, the attached first housing and second housing and the attached antenna are detached to unfold the telephone to set a usable state by a one-touch operation with a slide button.
