    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.

    Abstract: A foldable portable telephone is made up of an upper casing having a receiver portion, and a lower casing having a transmitter portion. The lower casing is rotatably connected to the upper casing by a hinge. When the lower casing is rotated away from the upper casing, the receiver portion is moved to protrude from the upper casing. At this instant, the telephone is brought into an off-hook state. When the lower casing is rotated onto the upper casing, the receiver portion is retracted into the upper casing while the telephone is brought into an on-hook state. The receiver portion, when protruded from the upper casing, increases the distance between an antenna and the user's ear. In this condition, the antenna is not influenced by the user's body and, therefore, maintains a sufficient antenna gain.

    Abstract translation: 可折叠便携式电话机由具有接收器部分的上壳体和具有发射器部分的下壳体组成。 下壳体通过铰链可旋转地连接到上壳体。 当下壳体旋转离开上壳体时，接收器部分被移动以从上壳体突出。 在这个时刻，电话被带到摘机状态。 当下壳体旋转到上壳体上时，当电话机处于挂机状态时，接收器部分缩回到上壳体中。 当从上壳体突出时，接收器部分增加了天线与用户耳朵之间的距离。 在这种情况下，天线不受用户身体的影响，因此保持足够的天线增益。

    Abstract: An antenna handling mechanism incorporated in a portable radio communication apparatus and including an antenna which can be pulled out of the casing of the apparatus, as desired. When the antenna is received in the casing, the lower end of thereof is locked by a latch mechanism disposed in the casing. In this condition, as the tip of the antenna is pressed, the latch mechanism unlocks the lower end of the antenna and, at the same time, pushes the antenna out of the top of the casing by a pushing stroke. When the antenna being inserted into the casing reaches a predetermined position, the latch mechanism locks the lower end of the antenna.
