A sliding module for a sliding-type portable terminal as claimed in claim 7, wherein the first and second guide rails have first and second stopper portions formed thereon to contact the first and second rail guide portions as the catching movement portions of the first and second rail guide portions rotate along the curve of the first and second guide rails and to stop them from rotating. 9. A sliding module for a sliding-type portable terminal as claimed in claim 5, further comprising at least one support member positioned between the first and second rail guide portions to support them. 10. A sliding module for a sliding-type portable terminal as claimed in claim 5, wherein the second guide rails have first and second catching portions formed thereon in a curved shape to catch catching movement portions of the first and second rail guide portions, the first catching portions are adapted to catch the catching movement portions of the first rail guide portions and rotate along a curve, and the second catching portions are adapted to catch curved movement stoppers of the second rail guide portions and rotate along a curve. 11. A sliding module for a sliding-type portable terminal as claimed in claim 10, wherein the main housing has a first recessed region and a second region positioned adjacent to the first recessed region, the second region protruding a predetermined height relative to the first recessed region. 12. A sliding module for a sliding-type portable terminal as claimed in claim 11, wherein the second region is provided with, on its upper surface, a microphone device and a first key array made up of a number of keys arranged to be exposed and hidden as the sliding housing slides along a curve in the longitudinal direction. 13. A sliding module for a sliding-type portable terminal as claimed in claim 11, wherein the sliding housing has a first coupling region formed on the rear surface thereof to be coupled to and separated from the first region and a second coupling region positioned adjacently to the first coupling region while being recessed a predetermined depth relative to the first coupling region to be coupled to and separated from the second region. 14. A sliding module for a sliding-type portable terminal as claimed in claim 11, wherein, when the sliding housing is slid away from the main housing along the longitudinal direction, the first and second catching portions of the second guide rails catch the catching movement portions of the first and second rail guide portions and cause the rail guide portions to slide along the curve of the first guide rails; wherein after the sliding, the stopper portions stop the second guide rails, and the second region of the main housing is arranged next to an upper surface of the sliding housing; and wherein, when the sliding housing is slid toward the main housing along the longitudinal direction, the first and second catching portions of the second guide rails catch the movement stopper portions and the first and second rail guide portions are guided along the curved first and second guide rails to their original position in the opposite direction to the longitudinal direction. 15. A sliding module for a sliding-type portable terminal as claimed in claim 5, wherein the first guide rails are shorter than the second guide rails. 16. A sliding module for a sliding-type portable terminal as claimed in claim 1, wherein the sliding housing is provided with, on its upper surface, a speaker device, a large LCD positioned adjacent to the speaker device, and a second key array made up of a number of keys arranged adjacent to the large LCD. 17. A sliding module for a sliding-type portable terminal as claimed in claim 1, wherein a pair of sliding rail modules are to expose and hide predetermined regions of the upper surfaces of the housing. 18. A sliding module for a sliding-type portable terminal comprising: a main housing extending along a longitudinal direction; a sliding housing adapted to slide along a curve in the longitudinal direction toward or away from the main housing; and a plurality of sliding modules positioned on both sides of the housings to couple the sliding housing to the main housing in such a manner that the sliding housing can slide with respect to the main housing along a curve in the longitudinal direction and adapted to simultaneously rotate about a number of hinge axes according to sliding a predetermined length so that the upper surfaces of the housings are exposed and hidden. 19.
