BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal, and more particularly, to a rotating hinge for easily rotating the cover in a transverse semi-automatic manner with respect to a main body and a portable terminal of a rotation type using the same.

In general, a communication terminal may be classified into a wired or wireless communication terminal, and a wired communication terminal is an office or home telephone, and a wireless communication terminal is a PCS, a cellular phone, or a PDA. Wireless communication terminals are commonly referred to as mobile communication terminals or portable terminals because they provide portability and mobility to a user.

Due to the development of the technology, such a portable terminal provides a user with text information, image information, MP3, games, etc. beyond the step of delivering only simple voice information. The type of the mobile terminal is largely provided with a bar type and a cover. It can be divided into flip type and folder type.

The folder-type portable terminal can solve the problem of having a long length of a bar-type or flip-type portable terminal by opening and closing a folder when making a call or carrying, but the hinge portion connecting the upper folder and the lower folder is easily damaged. There is a problem.

In order to solve the problem of the folding portable terminal, a sliding portable terminal in which the cover is moved up and down in a semi-automatic manner with respect to the main body of the portable terminal has been proposed.

On the other hand, the mobile terminal is expected to expand the viewing of music and music at the CD level by DMB (Digital Multimedia Broadcasting) service. A portable terminal capable of receiving a video or MP3 service is also called a personal multimedia player (PMP). Here, DMB can be divided into terrestrial DMB and satellite DMB. Satellite DMB is broadcasted using satellite, and the low-inner city area receives a signal by using a kind of repeater called Gap Filler. Will be provided.

However, since the display window of the conventional portable terminal has a longer length in the vertical direction than in the horizontal direction, it is not suitable for use of image information. That is, since general image information is provided with a width wider than a vertical, it cannot be appropriately displayed on a display window of a mobile terminal having a long length in the vertical direction.

Therefore, in order to solve such a problem, a portable terminal that can be used by rotating the upper folder in the horizontal direction with respect to the lower folder is used as a type of folding portable terminal.
