Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a portable communication device having a small and lightweight thin casing structure, such as a mobile phone, a PHS, a portable visual phone, and a portable information terminal.
[0002]
[Prior art]
Antennas used in portable communication devices such as mobile phones and PHS mobile terminals usually have directivity, and the sensitivity is highest when the antenna polarization plane on the reception side matches the antenna polarization plane on the transmission side. Good communication is possible. In the portable communication device system, the antenna polarization plane on the transmitting side is vertical, and the antenna polarization plane on the portable communication device side on the receiving side is also vertical with the portable communication device in a normal use state upright. The antenna is set to be Therefore, it is preferable that the portable communication device is set up as much as possible in order to improve reception sensitivity in a state of being placed on a table and waiting. In addition, having the device stand at an appropriate angle has many advantages such as easy handling of the mobile communication device and easy viewing of the liquid crystal display unit.
[0003]
The first conventional example will be described with reference to FIGS. 6, 7 and 8, and the second conventional example will be described with reference to FIG.
[0004]
In the first conventional example, a stand foot 34 is provided on the bottom surface of a portable communication device 31 having an antenna 32. The stand foot 34 is provided so as to be able to enter and leave the stand foot storage portion 35. When the stand foot 34 is placed on a table, the stand foot 34 is taken out from the back side of the liquid crystal display portion 33 provided in the portable communication device 31 to increase the bottom surface area. To make them independent. (Japanese Patent Laid-Open No. 9-321852)
In the second conventional example, when the portable communication device 31 having the antenna 32 is placed on a table, the protective cover 37 of the key operation button 36 disposed on the portable communication device 31 is further rotated from the normal deployment position A. The mobile communication device 31 is moved and arranged at the position B on the back side of the mobile communication device 31, and the mobile communication device 31 is made independent by using the protective cover 37 as a stand. (Japanese Patent Laid-Open No. 4-276957)
[0005]
[Problems to be solved by the invention]
In the first conventional example, the mobile communication device cannot be set at an arbitrary angle with respect to the table top surface, but is merely made to stand at right angles, and the visibility and handling of the liquid crystal display unit are poor. The stand foot is thin and small in the width direction, so it is placed in the lower part of the portable communication device, so the stand foot size is small and it is very weak, unstable and falls down against slight vibrations, shocks and table top tilts. Cheap.
[0006]
In the second conventional example, it is impossible to make the mobile communication device of the type without the protective cover of the key operation button stand by itself. In the type having the protective cover of the key operation button, the entire portable communication device becomes thicker by the thickness of the protective cover. In addition, since the protective cover made of light plastic is used as a stand, if the mobile communication device is self-supporting, the mobile communication device body, which is heavier than the protective cover, will be above the stand. Become. Therefore, as in the first conventional example, it is weak against slight vibrations and shocks and easily falls down.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problem, in a portable communication device having a thin housing structure having at least a display unit, an operation unit, a microphone, a speaker, and a battery unit, the main body middle portion of the portable communication device is used as a fulcrum. A rotation support unit for rotating the battery unit from the lower part of the apparatus main body so as to be opened and closed is provided, and the apparatus main body is made to stand by using the rotated battery unit as a stand.
