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

1 and 2 relate to an embodiment of the present invention. FIG. 1 is a perspective view showing a state in which an image display section of a mobile phone is opened, and FIG. 2 is a view showing a state in which the image display section of the mobile phone is closed. FIG.

In the portable telephone of the present invention, a concave portion 2 is provided on the front side of a telephone body 1 as shown in FIGS.
A telephone body side image display unit 4 is provided on the bottom surface 3 of the recess 2, and an auxiliary image display unit 5 formed to a thickness corresponding to the depth of the recess 2 is electrically connected to the side of the recess 2 and hinged. 6 are rotatably connected to each other. In addition,
Reference numeral 8 in the figure denotes an antenna, and 9 denotes an operation button.

The auxiliary image display unit 5 configured as described above is
Normally, as shown in FIG. 2, it is closed and covers the image display surface 4a of the telephone body, and is housed integrally with the telephone body 1. When transmitting characters and the like using the image display unit, the auxiliary image display unit 5 is opened as shown in FIG. 1, and the telephone body 1 side image display surface 4a and the auxiliary image display surface 5a are opened.
The image display surface 4 of the telephone body 1
a is enlarged about twice on the auxiliary image display surface, and it becomes possible to increase the amount of electric transmission of characters and the like in proportion to the enlarged display area.

In this embodiment, the auxiliary image display unit 5
Has been described on one side surface of the telephone body side image display unit 4, but the invention is not limited thereto.
, The display area can be further enlarged.

[0013]

According to the present invention, the auxiliary image display device is rotatably mounted in the vicinity of the display portion of the image display device on the main body side of the portable telephone via the hinge in addition to the display portion.
When the auxiliary image display device is not used, the auxiliary image display device is closed on the phone body side and stored integrally, and when the auxiliary image display device is used, the auxiliary image display device is opened to assist the main body image display surface. It is possible to enlarge the image display surface, and it is possible to increase the amount of electric transmission of characters and the like in proportion to the enlarged image display area. As a result, more messages can be transmitted as compared with a conventional mobile phone.
