Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a portable telephone, a PH
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing structure for a portable terminal in general including an S or the like, and particularly to a portable terminal housing structure that is foldable and has both small size and good operability and visibility.

[0002]

2. Description of the Related Art In recent mobile telephones, there has been a problem that key operations are complicated due to the development of software functions. In addition to the conventional pure voice communication, functions such as e-mail, Internet, image input / output, that is, PDA or portable small P
Some of the functions of C are being added to mobile phones.

[0003] On the other hand, the case of a portable telephone has been following a path of miniaturization year by year in consideration of portability.

[0004]

As described above, at present, it has reached a limit in achieving both miniaturization and conflicting elements such as operability and visibility in a single housing.

An object of the present invention is to provide a portable terminal housing structure which solves the above problems. In other words, by adopting a foldable housing, it is possible to realize good key input operation means and a large-screen display with high visibility to support information communication functions in addition to miniaturization of the housing and conventional voice calls. To provide a portable terminal device housing structure.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide at least three housings which can be folded into three housings.
Key input means for an information terminal function provided with input information display means for outgoing and incoming calls on the surface of the folded housing, and performing data communication such as characters and images on the surface of each housing panel in the expanded state And information display means.

[0007] According to the above means, the size is reduced by folding the casing into three when carrying, the portability close to that of the current mobile phone can be ensured, and the current mobile phone user can carry it without feeling uncomfortable.

On the other hand, when performing key input operation and screen display for data communication of characters and images, all three housings are opened to secure the area of the key operation unit and information display unit close to a portable small PC. Thus, even a current small-sized PC user can perform key input without a sense of incongruity, and operability is significantly improved as compared with a conventional mobile phone in which character input is performed.

Further, the key operation section and the information display section are separately or combined with the key operation section necessary for the telephone (power supply, ON / OFF hook,
By providing a redial, clear, 10 key, etc.) and an information display unit, reception / transmission / communication can be performed while folded.

[0010] In addition, the receiving, transmitting and talking functions can be provided on the microphone with the earphone together with the housing body, so that the operability can be further improved. That is, in the future, if simultaneous data transfer while making a call becomes possible, you can talk with both hands apart, for example, by operating the camera attached to the main body while talking,
Images can be transferred to the other party in real time, or messages can be sent to the other party while composing mail.

When the directions of the cases are different from each other, such as when talking on the case with the case folded or when performing communication such as the Internet while keeping the case open, the antenna is rotated in each direction. -By being able to move, it is possible to maximize the transmission and reception efficiency of the antenna.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment according to the present invention.
FIG. 1A is a perspective view showing a state in which a housing of a three-fold type mobile phone is folded, and FIG. 1A is a front view of the housing when folded, FIG.
Indicates the back surface of the housing when folded.

FIG. 2 is a perspective view showing a state in which the housing of the mobile phone is fully opened.

The three-fold type portable telephone according to the present embodiment comprises:
In the folded state as shown in FIG. 1, the receiver 4, the transmitter 5, the information display 6, the OFF hook key 7, the ON hook key / power key 8, and the numeric keypad input group 9 are provided on the housing surface 2 side (a). Is provided, and an extendable antenna 10 is provided on the side (b) of the rear surface 3 of the housing. In such a folded state, it has the same functionality, operability and portability as a current mobile phone.

On the other hand, when the housing is expanded as shown in FIG. 2, each of the three-folded housing is separated into an LCD panel 11, a center panel 12 and an input panel 13. The information display unit 14 and the small camera 15 with good visibility are attached. The small camera 15
Is provided with a mechanism capable of rotating the shaft 360 degrees. On the center panel 12 and the input panel 13, a full keyboard group 16 and other function key groups 17 as needed are provided. The element groups on the panels 11, 12, and 13 are connected to each other so that electric signals can exchange information. In addition, each panel is provided with a hinge mechanism 18 that can be freely set to an angle according to the situation when the panel is opened when inputting on a desk or operating on a hand. Have been.

FIG. 3 shows a folding method of the three-fold type portable telephone according to the embodiment shown in FIGS. 1 and 2, and shows that each panel can be easily folded and opened by the hinge mechanism 18. Show. That is, the folding from the fully opened state in FIG.
