Abstract:
1. A semi-automatic sliding device of a sliding-type portable communication terminal comprising a body housing and a sliding housing sliding on the body housing in a longitudinal direction, the sliding device comprising: a first member; a second member alternatively moving in a transverse or longitudinal direction of the first member while facing the first member; a guide for guiding the movement of the second member in a transverse or longitudinal direction with regard to the first member; and a ring shape elastic body rotatably coupled at opposite ends at its circumference to the first and second members and functioning as a semi-automatic driving source for driving the second member in the transverse or longitudinal directions, wherein the ring shape elastic body exerts a force, when deformed, in a direction from a center of the ring shape towards a periphery of the ring shape, wherein the force drives the second member towards a fully extended state if the second member is in a substantially extended state in the transverse or longitudinal direction, and wherein the force drives the second member towards a fully retracted state if the second member is in a substantially retracted state in the transverse or longitudinal direction.
