BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable wireless device, and more particularly to a portable wireless device characterized by reducing the influence of the antenna on the human body.

[0002]

2. Description of the Related Art In a conventional foldable portable wireless device, the upper casing is rotated by rotating the lower casing via a hinge portion, and the upper and lower casings are opened to make a call. The distance between the ear and the mouth at the time can be secured (that is, the housing has a V shape so that the positions of the earpiece and the talking part correspond to the positions of the ear and the mouth, respectively), and it is compact in the closed state. Therefore, there is an advantage (ease of use) of the foldable portable wireless device.

[0003]

However, although the foldable portable wireless device of recent years has such an advantage, the antenna and the ear (human body head) are being reduced due to the progress of thinner housing. Since the distance between the two becomes shorter, it is becoming difficult to secure the antenna characteristics due to the influence from the human body.

In order to secure the antenna characteristics,
It is necessary to separate the distance between the antenna and the human head by projecting the tubular portion of the housing that houses the antenna or rotating the antenna. As prior arts in which the antenna is rotated from the housing, Japanese Patent Laid-Open Nos. 8-298405, 9-232839 and 10-20990.
See, for example, No. 5 publication. In these, the antenna cylinder is always exposed from the housing, the range of rotation of the antenna is large, and the load is applied to the rotating shaft portion, which may damage this portion. Also, it takes time to align the antenna at a predetermined position.

On the other hand, in terms of design (commerciality),
There is a demand that the antenna tube part should not be exposed to the outside too much.

Reference is made to Japanese Patent No. 2576367 as a prior art of a foldable portable wireless device in which an antenna and an ear (human head) are separated from each other to reduce the influence from the human body. This allows the antenna to be pulled out near the hinge mechanism of the lower housing. This technology is excellent in that the antenna and the ear (human head) are separated without using any special additional equipment, but as the housing becomes thinner, the battery occupied in the lower housing Occupancy is high,
It is difficult to equip the antenna slidably.

A first object of the present invention is to provide a portable wireless device which can reduce the influence of the antenna on the human body, can cope with a thinner housing, and can meet the design requirements. .
