Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small-sized portable telephone, a personal handy phone (PHS), a visual phone with a solid-state image sensor camera, a portable information terminal, and the like.
The present invention relates to a lightweight portable communication device.

2. Description of the Related Art An antenna used in a portable communication device such as a mobile phone, a PHS, and a personal digital assistant normally has directivity, and the antenna polarization plane on the receiving side coincides with the antenna polarization plane on the transmitting side. When this is done, the sensitivity is highest and good communication is possible. In the system of the portable communication device, the transmitting-side antenna polarization plane is vertical, and the receiving-side mobile communication device-side antenna polarization plane is also in a normal use state and is vertical when the portable communication device is upright. The antenna is set to. Therefore, in order to improve the reception sensitivity in the state of placing it on a table or the like,
It is preferable to stand the portable communication device as much as possible.
Especially in the case of a metal desk such as a steel desk, the antenna characteristics can be reduced by separating the antenna from a metal object in the vicinity. In addition, making the portable communication 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.

A first conventional example will be described with reference to FIGS. 5, 6, and 7, and a second conventional example will be described with reference to FIG.

In the first conventional example, the stand foot 34 is provided on the bottom surface of the portable communication device 31 having the antenna 32 built therein so that the stand foot can be put in and taken out from the stand foot storage section 35, and when placed on a table,
Liquid crystal display unit 33 provided in the portable communication device 31
A method has been proposed in which the stand foot 34 is taken out on the back side of the stand and the bottom surface area is increased to make the stand stand. (JP-A-9
In the second conventional example, when the portable communication device 31 having the antenna 32 built-in is placed on the desk, the protective cover 37 of the key operation button 36 arranged on the portable communication device 31 is normally expanded. A method is proposed in which the portable communication device 31 is rotated further from the position A around the rotation fulcrum 38 and is disposed at the position B on the back side of the portable communication device 31, and the protective cover 37 is used as a stand to make the portable communication device 31 self-supporting. ing. (Japanese Patent Laid-Open No. 4-276957)

[0005]

In the first prior art example, the portable communication device cannot stand at an arbitrary angle with respect to the table top and is only allowed to stand at a right angle. The sex is also bad. In addition, the stand feet are thin and small in the width direction, so they are arranged at the bottom of the portable communication device, so the stand feet are small and extremely weak and unstable due to slight vibrations, shocks and tilting of the tabletop, and they fall over. Cheap.

In the second conventional example, it is impossible for the portable communication device of the type having no key operation button protective cover to stand on its own, and only the type having the key operation button protective cover is possible. In this type, the entire mobile communication device becomes thicker by the thickness of the protective cover. Further, when the protective cover is bent at the maximum angle, the stopper of the protective cover is only at the position of the rotary hinge, so the angle retention is weak and the strength is also weak.

When the protective cover, which is a front external component, is placed on a table, the external surface is likely to be scratched or dirty, and the external coating film is easily peeled off.

[0008]

The basic structure of the present invention for solving the above problems is to provide grooves extending parallel to each other in a thickness direction at predetermined angles on both side surfaces of a thin portable communication device body case. It is a piece different from the case, and is formed in a concave shape as a whole by providing stand legs extending in parallel in the same direction at both ends of a connecting portion having a width substantially the same as that of the case and having a length longer than the thickness of the case. A stand is provided, and both stand feet are fitted in the both grooves to fix the stand to the case. Further, a recessed step for accommodating the stand is provided on the front surface or the back surface of the case, when the stand is not used.

As shown in FIGS. 1 to 4, a more embodied and practically suitable structure is a thin portable communication device having a relationship of length>width> thickness or width>length> thickness.
A stand that is housed in a step on the front surface of the case where the key operation part of the portable communication device is located is pulled out from the step, and the stand feet are inserted into the grooves on both side surfaces of the case to stably stand on the tabletop or the like. Is.

As described above, according to the configuration and method of the present invention, a small and lightweight operability and a design excellent in a normal portable state and a telephone call in a hand are provided, and a tabletop is provided. If you want to place the stand on the stand, simply insert the stand into the guide groove in the thickness direction of the case, and you can stand by itself with the center of gravity of the mobile communication device close to the tabletop side. Since the span can be taken, it is strong against vibration, shock and a certain amount of inclination of the table top, and the portable communication device can be stably held by itself at the set angle. Therefore, the reception sensitivity of the mobile communication device is improved, and at the same time, the liquid crystal display is easy to see and the handling is excellent. Further, if a non-slip rubber material (not shown) is provided on the sloped portion provided at the bottom of the mobile communication device, a more stable self-standing table mounting can be obtained, and when the vibration of the mobile communication device is called. The lateral movement of the main body of the mobile communication device on the table top due to the vibration can be suppressed to a small level by the anti-slip rubber material absorbing the vibration.

Further, since the end surface of the tip portion of the stand portion is in contact with the table top surface, the surface of the stand portion forming a part of the external front case is not easily scratched or soiled.

The configuration of the present invention is particularly effective for mobile communication devices such as visual phones and personal digital assistants having a built-in image pickup function, and the mobile communication device can be independently set at an appropriate angle for image pickup, and is almost hand-free. It becomes possible to make an image pickup call in the state.

The present invention can be similarly configured in a mobile communication device having a relationship of width>length> thickness, and similar effects can be obtained.
