Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a communication device, and more particularly to a mobile communication device having an antenna.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, there are mobile phones, cordless phones, etc. as mobile communication devices having an antenna.

As shown in FIG. 2A, a mobile phone (including a cordless phone hereinafter) usually has a main body 21 and a retractable antenna 22 that extends from one end surface of the main body 21 and is expandable inside and outside the main body 21. And have. Usually, the retractable antenna 22 is retracted and housed inside the main body 21, and is pulled out from the main body 21 during a call. In the reception standby state, the retractable antenna 22 is often pulled out because the reception sensitivity is significantly reduced when the retractable antenna 22 is stored in the main body 21.

FIG. 2B is a state diagram showing a usage example of the mobile phone.

A user of a mobile phone carries the main body 21 of the mobile phone in a pocket 23. At this time, if the user is in the standby state for reception, the retractable antenna 22 is often in the pulled-out state in order to increase the reception sensitivity as shown in FIG. 2B, and there is a problem that portability is extremely poor.

For this reason, there is a device in which a built-in antenna is mounted on the rear surface of the telephone main body 21 separately from the retractable antenna 22 in order to secure the reception sensitivity while the retractable antenna 22 is housed in the main body 21.

However, such technical means have the following problems.

[0008]

[Problems to be solved by the device]

 That is, in the above-described technical means, when the mobile phone shown in FIG. 2A is stored in the pocket 23 or the like, the mobile phone or the like is likely to drop and is often damaged due to poor retention in the pocket 23 or the like. . Most of the built-in antennas are mounted on the back surface of the main body 21, and when stored in the pocket 23, the built-in antenna is often sandwiched between the human body and the main body 21. Is difficult to pull out.

The present invention has been made in view of such conventional problems, and an object thereof is to always ensure ideal reception performance and secure retention in a pocket or the like. An object of the present invention is to provide a portable communication device that is kept and has excellent portability.

[0010]

[Means for Solving the Problems]

 To achieve the above object, the present invention provides a mobile communication device having a main body and an antenna, wherein the antenna is installed so as to be inclined from a mounting portion at an upper end of a rear surface of the main body toward a rear surface thereof. It is characterized by rotating around the mounting part as a fulcrum.

[0011]

[Action]

 According to the mobile communication device having the above configuration, the antenna unit is installed so as to incline toward the back surface from the mounting portion at the upper end of the back surface of the main body portion, and has the antenna portion that rotates about the mounting portion as a fulcrum. When rotated and on the main body side, a gap is formed between the main body and the antenna to serve as a clip function.

[0012]

【Example】

 An embodiment of the present invention will be described in detail with a mobile phone as an example with reference to the accompanying drawings. FIG. 1A is a perspective view of a mobile phone according to the present invention. The mobile phone shown in the figure has a main body portion 11 and a clip-type antenna portion 12a.

The clip type antenna part 12 a is formed of an elastically deformable material, has a plate shape, and has a mountain-shaped non-slip 15 at a longitudinal end of one plane, and a longitudinal end with respect to the anti-slip 15. Has a mounting portion 14 having a thickness. The clip-type antenna 12a is attached to the upper end of the rear surface of the main body 11 so as to rotate about the attachment portion 14 as a fulcrum. The clip-type antenna 12a is inclined from the mounting portion 14 toward the back surface of the main body portion 11, and its tip is installed so as to be completely in contact with the back surface of the main body portion 11. The clip-type antenna portion 12b is rotated and brought into a state of protruding from the main body portion 11 to form the clip-type antenna portion 12b.

FIG. 1B is a state diagram showing an example of use of the mobile phone according to the present invention.

A user of a mobile phone carries the main body 11 of the mobile phone by storing it in a pocket 13. At this time, the clip type antenna section 12 is turned downward and rotated toward the main body section 11 side, and the elastically deformable material of the clip type antenna section 12 is used to widen the gap between the main body section 11 and the pocket 13. When sandwiched, the mobile phone can be stored in the pocket 13 with the clip-type antenna unit 12 exposed. The pocket 13 is firmly sandwiched between the clip-type antenna 12 and the main body 11. Further, during a call, as shown in FIG. 1 (a), the clip type antenna 12a can be rotated to the clip type antenna 12b.

It is possible to apply not only to mobile phones but also to various mobile communication devices such as cordless phones and pagers.

[0017]

[Effect of device]

 As described above in detail in the embodiments, according to the mobile communication device of the present invention, the antenna is always exposed to the outside of the pocket or the like even when it is stored in the pocket or the like, so that the ideal reception performance is always obtained. Since it can be secured and the antenna itself has the function of a pocket clip, it can be expected to have a secure holding property in a pocket or the like and portability. Furthermore, since the need for a built-in antenna etc. is eliminated and the internal circuit can be made compact, it can be expected that a smaller device can be provided at low cost.
