Sliding Portable Terminal {SLIDING TYPE PORTABLE TERMINAL}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal, and more particularly, to a sliding type portable terminal which is slidably coupled to each other with a pair of housings facing each other.

In general, a portable terminal is a device that allows a user to carry and use a mobile communication function. The portable terminal may be classified into a bar type, a flip type, and a folder type terminal according to its appearance.

The bar-type terminal is a type in which a data input / output means, a transmitter, and a receiver are mounted in a main body housing, and a keypad, which is a data input means, is exposed at all times, which may cause a malfunction, and the distance between the transmitter and the receiver. There is a limit to miniaturization due to securing problems.

The flip terminal comprises a main body, a flip, and a hinge module that connects the main body and the flip. The flip terminal includes a data input / output means and a handset, and the flip is a keypad for the data input means. Overwrite can prevent malfunction, but with the commercialization of clamshell terminals, most of the flip-type terminal market has been encroached.

The folder-type terminal is composed of a main body, a folder, and a hinge module for rotatably connecting the main body and the folder so that the folder is rotated and opened and closed. In the call mode, the folder is opened to secure a sufficient distance between the transmitter and the receiver, which is advantageous in miniaturization.
