FIELD OF THE INVENTION COMPLEX HINGE APPARATUS AND DIFFERENT MEANING COMPLEX HINGE APPARATUS THEe CELL PHONE}

The present invention relates to a mobile terminal having a composite hinge device and a composite hinge device thereof, and more particularly, to allow the lower and upper units each having a lower and an upper display portion on the upper surface thereof to be rotatable by sliding each other. The present invention relates to a compound hinge device and a portable terminal having the compound hinge device thereof, which allow a more convenient and various type of display unit to be used.

 As is well known, portable terminals generally have a flip type, a folder type, and a sliding type according to their appearance and operation, and a portable type and a sliding type mobile terminal are used.

In the above-described sliding type mobile terminal, two sliding bodies (first and second units) are disposed to overlap each other, and the display unit and the key input unit are disposed in the same direction on each of the sliding bodies.

Such a sliding type mobile terminal may relatively move the sliding body in the front side to expose the display unit or the key input unit hidden in the rear side. For example, there is a slide-type portable terminal that can push up the front sliding body to expose the key input unit formed on the front of the rear sliding body.

In addition, as another example, there is also a portable terminal that can expose the display formed on the front of the sliding body of the rear by moving the front sliding body formed with the key input portion down.

However, such a conventional sliding type mobile terminal has a problem in that the display unit can be configured to be small as the key input unit is necessary because the information can be inputted or sent information by the key input unit.

In view of this point, recently, a touch type portable terminal without a key input unit has been developed and released as a product.

However, since the touch-type portable terminal has only one touch-type display unit on the front side, the user needs to view multimedia information such as watching a movie or TV or reading a book with a wider display unit at a time. It does not meet the needs.
