A slide type communication terminal designed to allow a sliding operation to be smoothly completed by means of a driving unit and a travel-enlarging member. In the communication terminal having a first body and a second body, a driving unit includes a motor and a pinion connected to the motor. A first hinge has a rack gear meshed with the pinion and a travel-enlarging member connected to the rack gear. A second hinge has a contact member protruded therefrom to contact the travel-enlarging member. Rotation of the pinion in response to the drive force of the driving unit is converted into a linear movement of the rack gear, and a distance of the linear movement of the rack gear is enlarged by means of the travel-enlarging member, so that the second body fixed to the second hinge is slid to an enlarged travel distance.

What is claimed is: 1. A slide type communication terminal having a first body and a second body slidably moved on the first body, the communication terminal comprising: a driving unit including a motor for supplying a rotational drive force required for a sliding operation of the second body, and a rotatable pinion connected to the motor in an axial direction; a first hinge fixed at an underside to the first body, and including a rack gear meshed with the pinion to be linearly moved by the rotational drive force from the driving unit, and a travel-enlarging member connected to the rack gear to enlarge a travel distance of the second body; and a second hinge fixed at a top to the second body, and including a contact member protruded therefrom to contact the travel-enlarging member, wherein rotation of the pinion in response to the drive force of the driving unit is converted into a linear movement of the rack gear, and a distance of the linear movement of the rack gear is enlarged by means of the travel-enlarging member, so that the second body fixed to the second hinge is slid to an enlarged travel distance. 2. The communication terminal as set forth in claim 1, wherein the rack gear is provided to the underside of the first hinge such that the rack gear can be linearly moved by virtue of rotation of the driving unit in a state of being meshed with the pinion, and the travel-enlarging member comprises a rotatable lever, wherein the lever is rotated around a hinge shaft positioned on the first hinge by contact between a protrusion formed on a rear side of the rack gear opposite to a tooth array of the rack gear and a protrusion-receiving groove perforated through the lever corresponding to the protrusion to guide the protrusion according to the linear movement of the rack gear, and wherein as the lever is rotated, the second body fixed to the second hinge is slid by contact between the contact member of the second hinge and a guide groove perforated through the lever corresponding to the contact member to guide the contact member. 3. The communication terminal as set forth in claim 2, wherein a distance L2 from the hinge shaft to the contact member of the second hinge is larger than a distance L1 from the hinge shaft to the protrusion formed on the rack gear, and a ratio of the travel distance of the second hinge to the travel distance of the rack gear is enlarged by a ratio L2/L1 of the distance L2 from the hinge shaft to the contact member to the distance L1 from the hinge shaft to the protrusion. 4. The communication terminal as set forth in claim 3, wherein the protrusion is positioned between the hinge shaft and the contact member on the lever. 5. The communication terminal as set forth in claim 3, wherein the hinge shaft is positioned between the protrusion and the contact member on the lever. 6. The communication terminal as set forth in claim 2, wherein the first hinge further comprises a rack guide member for guiding the rack gear in a straight line. 7. The communication terminal as set forth in claim 1, wherein the first hinge further comprises first guide members disposed on both sides of the first hinge in a longitudinal direction, and the second hinge further comprises second guide members each disposed on both sides of the second hinge corresponding to each of the first guide members, each of the first guide members being inserted into each of the second guide members, so that the second hinge is slid while being guided with respect to the first hinge in a longitudinal direction. 8. The communication terminal as set forth in claim 7, wherein the second guide members are provided as rod-shaped guide shafts symmetrically disposed at both sides of the second hinge in a longitudinal direction, and the first guide members are provided as shaft supports, each having a penetration hole through which the guide shaft is guided. 9. The communication terminal as set forth in claim 7, wherein the first guide members are provided as guide grooves or guide flanges symmetrically disposed at both sides of the first hinge and bent in a longitudinal direction, and the second guide members are provided as guide flanges or guide grooves formed to correspond to the first guide members, so that each of the guide flanges can be inserted to each of the guide grooves to move between the guide grooves in a longitudinal direction. 10. The communication terminal as set forth in claim 1, wherein the driving unit further comprises a power transmission part connected to a rotational shaft of the motor in an axial direction to transmit or receive a drive force of the motor or an external force through a pair of members selectively meshed with each other by means of an elastic member, and the pinion is fixed to a rotational shaft of the power transmission part in an axial direction. 11. The communication terminal as set forth in claim 10, wherein the driving unit further comprises a housing for receiving the power transmission part and the motor in such a way that an outer peripheral surface of the motor is fixed to an inner peripheral surface of the housing, the housing being fixed to a underside of the first hinge and having a penetration hole formed at one side of the housing, and the pinion is fixed to the power transmission part through the penetration hole of the housing. 12. The communication terminal as set forth in claim 1, wherein the motor comprises a geared motor having a gear box for enlarging a driving torque. 13. The communication terminal as set forth in claim 10, wherein the power transmission part comprises a hinge shaft fixed to the rotational shaft of the motor to transmit the drive force of the motor, a slide cam selectively meshed with the hinge shaft at every predetermined angle, and a guide cam relatively restricting the slide cam in a rotational direction while receiving the slide cam movably in an axial direction, the elastic member providing an elastic force to allow the hinge shaft and the slide cam to be selectively meshed with each other by means of the elastic member, the pair of members comprising the hinge shaft and the slide cam. 14. The communication terminal as set forth in claim 13, wherein the hinge shaft has a tapered protrusion, acting as a male cam, and the slide cam has a groove corresponding to the protrusion of the male cam, acting as a female cam, the hinge shaft and the slide cam are meshed with each other every 180째. 15. The communication terminal as set forth in claim 13, wherein the elastic member is positioned between the slide cam and the guide cam, and presses the slide cam towards the hinge shaft. 16. The communication terminal as set forth in claim 15, wherein the elastic member is adapted to provide an elastic force larger than the drive force of the motor and smaller than an external force, so that in a case of an automatic sliding operation, the elastic member may be expanded, allowing the slide cam and the hinge shaft to be rotated in a meshed state, and in a case of a manual sliding operation by application of external force, the elastic member may be compressed to disengage the hinge shaft from the slide cam, allowing the pinion to be rotated by the external force. 17. The communication terminal as set forth in claim 13, further comprising: a sensor part including a contact-type sensor or a non-contact type sensor to detect rotation of a specific portion of the hinge shaft with respect to the motor by a predetermined angle; and a drive controller to control operation of the motor by means of a signal from the sensor part, whereby completion of the sliding operation is controlled. 18.
