Abstract: Disclosed is a slide type portable terminal which includes a clean back cover covering a back surface of a sliding housing during the sliding of the sliding housing. The cover prevents the back surface from being exposed. The terminal further has a double sliding assembly structure to improve the assembly strength in sliding. The slide type portable terminal including a body housing and a sliding housing sliding relative to the body housing while facing the body housing includes a guide plate formed in the body housing to double guide a sliding of the sliding housing, and a double sliding plate formed in the sliding housing to be double assembled with the guide plate and engaged with the guide plate to slide.

Abstract: Disclosed herein is a sliding/folding combination type portable digital communication apparatus that includes a body; a sliding folder having a first position in which it is constrained on the body, a second position in which it has slid a predetermined distance while continuously facing the body, and a third position in which it has rotated away from the body after the sliding in such a manner that it does not face the body; and a sliding hinge module positioned between the body and the sliding folder to travel together with the sliding folder and provide a force necessary for folding/unfolding the sliding folder. The user can conveniently use a single communication apparatus having the advantages of both sliding-type and folding-type apparatuses.
