Disclosed is a mobile communication device comprising a slide cover being longitudinally slid towards or away from a main body of the mobile communication device according to use of the mobile communication device. The mobile communication device includes the main body having a liquid crystal display and guide holes formed at both sides of the liquid crystal display; a slide cover including a speaker, and being provided on a front surface of the liquid crystal display so as to be slid along a longitudinal direction of the main body, thus exposing the entire or a portion of the liquid crystal display; a pop-up module being connected to the slide cover, and being inserted into the guide holes so that the slide cover is slid along the front surface of the liquid crystal display of the main body; and a side grip provided at a side surface of the main body so as to fix or release a position of the pop-up module.

What is claimed is: 1. A mobile communication device comprising: a main body including a display and guide holes formed at both sides of the display; a slide cover sliding between a dosed position and an opened position over a front surface of the display in a longitudinal direction of the main body; a pop-up module connected to the slide cover and inserted into the guide holes for sliding the slide cover over the front surface of the display; a side grip provided at a side surface of the main body so as to fix the closed and opened positions, the side grip including: a locking plate for locking to and unlocking from a locking groove of the pop-up module; a one-touch button installed on an external surface of the side grip, wherein pressing of the one-touch button allows rotation of the locking plate, thus separating the locking plate from the locking groove; and a locker unit installed at a designated position of the external surface of the side grip to maintain a locked state of the locking plate; and a coiled compression spring providing a sliding elastic force to slide the slide cover from the closed position to the opened position. 2. The mobile communication device as set forth in claim 1, wherein guide grooves are formed at both sides of the display in the longitudinal direction to guide the slide cover. 3. The mobile communication device as set forth in claim 1, wherein the display serves as a main display when the slide cover is slid away from the main body to expose the entire display, and serves as a sub-display when the slide cover is slid towards the main body to partially expose the display. 4. The mobile communication device as set forth in claim 1, wherein the slide cover is slid away from the main body during use of the mobile communication device, and is slid towards the main body during nonuse of the mobile communication device. 5. The mobile communication device as set forth in claim 1, wherein the pop-up module includes: a head section connected to the slide cover; and at least one bar installed at an end of the head section and inserted into the corresponding guide holes, the at least one bar receiving the coiled compression spring. 6. The mobile communication device as set forth in claim 5, wherein the head section includes a connection plate for connecting the at least one bar to an other bar. 7. The mobile communication device as set forth in claim 5, wherein a flexible circuit is installed within an other bar, and a locking groove is formed in a lower end of the at least one bar. 8. The mobile communication device as set forth in claim 1, wherein an upper end of the locking plate contacts the one-touch button, and a lower end of the locking plate is provided with a protrusion for inserting into the locking groove. 9. The mobile communication device as set forth in claim 8, wherein the protrusion includes an incline plane serving to guide the locking plate into the locking groove. 10. The mobile communication device as set forth in claim 8, wherein a plate spring is installed on a rear surface of the protrusion of the locking plate, and provides an elastic force to the protrusion so as to rotate the locking plate. 11. The mobile communication device as set forth in claim 1, wherein a hinge unit is installed in a central portion of the locking plate to facilitate rotation of the locking plate. 12. The mobile communication device as set forth in claim 1, wherein the locker unit includes: a sliding button protruding from the external surface of the side grip, and slidable by an external force; and a locking section installed within the side grip and integral with the sliding button, wherein the locking section moves together with the sliding motion of the sliding button so as to fix or to release the locking plate. 13. The mobile communication device as set forth in claim 12, further comprising: a contacting protrusion installed at an upper end of the locking section, for contacting and fixing the locking plate according to the sliding motion of the locking section; and a stopper installed at a lower end of the locking section so as to fix the position of the locking section. 14. The mobile communication device as set forth in claim 13, wherein the stopper includes: a stopping protrusion connected to the locking section; and at least one recess installed in a designated location of an inner wall of the side grip, and serving to accommodate the stopping protrusion so as to fix the position of the locking section.
