A portable radio telephone is
It is desired that the operability is good in the talking state and the compact form is in the storing state.

In order to achieve these objects, the conventional portable radio telephone is divided into a main body, and has a operability first state (call state) and a storable second state (storage state). Many proposals have been made to change the form. However, in the above-mentioned conventional example in which the main body is divided into three parts, since the whole body is stored in a rod-like state, the total length cannot be made shorter than the distance between the human ear and the mouth which is inevitably determined in ergonomics. In addition, since the numeric keypad is always exposed, there are problems in erroneous operation and dustproofness in the second state.

Further, in the conventional example in which the main body is divided into two parts and is foldable, the movable part is opened in a "<" shape to make a call, so that the appropriate parts suitable for the three elements of the grip part, the ear, and the mouth are provided. I couldn't take the angle. For this reason, some of the conventional examples of this kind have been dealt with by protruding the speaker part from the main body, but in this case, there is a problem in compactness in the stored state.

Further, in Japanese Patent Laid-Open No. 2-44843, which emphasizes compactness in storage, as shown in FIG. 6 (b), the face is not fitted and the gap L2 between the face and the main body is small. It wasn't easy to grasp.

The object of the present invention is to solve the above-mentioned problems. In the first state (communication state), the face has a shape that is easy to grip and the second state (storage state). The purpose of the present invention is to provide a compact portable wireless telephone with excellent storability.

[0010]

To achieve the above object, in the present invention, the main body is divided into a first device, a second device having a speaker, and a third device having a microphone. In the portable wireless telephone in which the second device and the third device are movably connected to the first device, the numeric keypad is exposed in the first state and the numeric keypad is hidden in the second state. The third device is configured to be foldable.

[0011]

According to the present invention, since the main body is divided into three parts, in the first state, the first device serves as the grip portion, the second device serves as the ear, and the third device serves as the mouth. It is possible to adjust to each suitable angle, and the second
In the state, the third device is formed so as to be foldable so that the numeric keypad can be exposed in the first state and the numeric keypad can be hidden in the second state.
