Hereinafter, the structure of the mobile telephone terminal according to the present invention will be described.

The terminal body 11 and the terminal cover 12 are coupled to each other so that the terminal cover can rotate.

The terminal cover 12 includes a first case 13 and a second case 23.

Here, the part coupled to the terminal body 11 so as to be rotatable is the first case 13.

The first liquid crystal screen 14 is formed on the first case upper surface 13-1, and the second liquid crystal screen 15 is formed on the lower surface 13-2.

The third liquid crystal screen 24 is formed on the upper surface 23-1 of the second case.

The first LCD screen 14 and the third LCD screen 24 are main LCD screens capable of displaying all kinds of characters, pictures, videos, etc., and the second LCD screen 15 is an auxiliary display displaying only basic numerals or characters. LCD screen.

In the present embodiment, a configuration in which the first liquid crystal screen 14 is used as the main liquid crystal screen for text or picture display and the third liquid crystal screen 24 as the main liquid crystal screen for video display is taken as an example, but this is only one embodiment. Both the first liquid crystal screen and the third liquid crystal screen can be used as a liquid crystal screen capable of displaying all of text, pictures, and video.

The first case 13 and the second case 23 are coupled so that the first case top surface 13-1 and the second case bottom surface 23-2 are spaced apart by a slight distance, and the top surface 13 of the first case 13 is separated. -1) is covered by the second case.

Thus, the first liquid crystal screen 14 is covered by the second case 23.

Here, the guide protrusions 16 are formed on both sides of the first case 13 along the surface.

In addition, a case accommodating groove 25 is formed in the rear surface 23-2 of the second case so that the first case 13 can be inserted therein.
