DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display device for a portable telephone, and more particularly to an image display device for a portable telephone which enlarges the image display area to increase the amount of electric transmission of characters and the like.

[0002]

2. Description of the Related Art Recently, a cellular phone provided with a liquid crystal image display device for transmitting characters and the like on a part thereof has been widely used.

[0003] The image display screen of the telephone is generally provided on the front side of the portable telephone so that an input can be made while looking at the display screen.

[0004]

However, the image display screen has a small image display area due to the small size of the mobile phone itself, and the transmission amount of characters and the like is limited to the range of the area. There was a problem that only business requirements could be transmitted.

Accordingly, the present invention has been made in view of the above problems, and has as its object to provide an image display device of a portable telephone capable of enlarging an image display area and obtaining a larger amount of electric transmission than before.

[0006]

According to the present invention, there is provided an image display apparatus for a portable telephone according to the present invention.
Is a mobile phone image transmission device for e-mail transmission,
An auxiliary image display unit is provided on the upper surface of the image display unit provided in the telephone body, and the two image display units are electrically connected and slidably connected in a planar manner via a guide groove. The auxiliary image display section is placed on the surface of the main body side image display section and stored, and when used, the auxiliary image display section is slid sideways to expose the main body side image display face, and the main body side image display is performed by the auxiliary image display section It is characterized in that the surface is enlarged and used.

According to the first aspect of the present invention, the auxiliary image display section is provided so as to be slidable in a plane with respect to the surface of the image display section provided in the portable telephone body. When storing and superimposing on the surface of the image display section on the telephone body side, and when transmitting characters, etc., slide the auxiliary image display section to the side to expose the surface of the image display section on the telephone body side, thereby displaying the image on the telephone body side. The display surface is enlarged about twice on the auxiliary image display surface, and it becomes possible to increase the transmission amount of characters and the like in proportion to the area thereof.

[0008]

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

FIGS. 1 and 2 relate to an embodiment of the present invention. FIG. 1 is a perspective view showing a state in which an auxiliary image display section of a mobile phone is slid, and FIG. It is a perspective view showing the state where it was stored in the main part side.

As shown in FIGS. 1 and 2, the portable telephone of the present invention has a concave portion 3 having a dovetail groove 2 having two parallel sides formed on the front side of the telephone main body. And an auxiliary image display section 5 having a thickness corresponding to the depth of the concave portion 3 and two parallel sides formed so as to be slidably fitted in the dovetail groove 6 of the telephone body 1.
Are slidably fitted, and the auxiliary image display unit 5 and the telephone body 1 side are electrically connected. In addition, the code | symbol 8 in a figure shows an antenna, 9 shows an operation button.

The auxiliary image display unit 5 configured as described above is
Normally, as shown in FIG. 2, it is slid and pushed into the telephone main body 1 side to cover the surface of the image display section on the telephone main body 1 side and housed integrally. When transmitting characters and the like, the auxiliary image display unit 5 is pulled out to the side to expose the image display surface 4a of the telephone body 1 side, so that the image display surface 4a of the telephone body 1 is connected to the auxiliary image display surface 5a. It is enlarged about twice, and it becomes possible to increase the transmission amount of characters and the like in proportion to the enlarged image display area.

[0012]

According to the present invention, in addition to the display portion of the image display device on the main body side of the portable telephone, the auxiliary image display device is slidably mounted on the surface so that the image display surface can be slid. When not in use, push the auxiliary image display device into the phone body side to house it integrally, and when using the display surface, pull out the auxiliary image display device to the side to expose the main body image display surface, and The display surface can be enlarged on the auxiliary image display surface, and the amount of electric transmission of characters and the like can be increased in proportion to the enlarged area of the display unit. As a result, more messages can be transmitted as compared with a conventional mobile phone.
