Disclosed is a sliding module for a portable terminal including a main housing and at least one sub-housing movably mounted on the main housing to perform an opening/closing motion. The sliding module includes a disc rotatably mounted on the main housing; links each of which has a first end coupled to the disc and a second end coupled to one of the sub-housings; and an elastic means providing the disc with a rotating force, wherein the rotating force rotates the disc such a manner that the other ends of the links can move toward the disc in a first interval and the one ends of the links can move away from the disc in a second interval. The first and second sub-housings of the sliding module can realize semi-automatic opening/closing operation of the terminal.

What is claimed is: 1. A sliding module for a portable terminal including a main housing, the sliding module comprising: at least one sub-housing movably mounted on the main housing in an opening/closing motion, the at least one sub-housing moving with respect to the main housing in a first interval and a second interval; a disc rotatably mounted on the main housing and rotating about a rotation center; a plurality of links, each of which has a first end coupled to the disc and a second end coupled to each of the at least one sub-housing; and an elastic means providing the disc with a rotating force moving the at least one sub-housing toward the main body in the first interval and moving the at least one sub-housing away from the main body in the second interval, the elastic means passing through the rotation center when the at least one sub-housing moves from one of the first interval and the second interval to the other of the first interval and the second interval. 2. A sliding module for a portable terminal as claimed in claim 1, wherein the elastic means is a coil spring. 3. A sliding module for a portable terminal as claimed in claim 1, wherein the at least one sub-housing comprises a pair of sub-housings mounted on the main housing in side by side relation. 4. A sliding module for a portable terminal as claimed in claim 3, wherein the pair of sub-housings are subjected to a first driving force, in the first interval, which is oriented to move the sub-housings towards each other, and subjected to a second driving force, in the second interval, which is oriented to move the sub-housings away from each other. 5. A sliding module for a portable terminal as claimed in claim 3, wherein the links are symmetrically installed with respect to the rotation center. 6. A sliding module for a portable terminal as claimed in claim 1, wherein the elastic means is a coil spring having a first end supported on the main housing and a second end supported on the disc.
