Abstract: A portable terminal includes a display module and a case member coupled to the display module. A face of the case member is formed to have a center portion and an edge, which are different from each other in their heights to thereby support a center portion of the display module in lengthwise and widthwise directions of the display module respectively. The portable terminal configured above supports a rear face of the flat display module using at least one of a portion protruded from the case member and a stiff material film, to thereby diffuse an impact exerted on a display device to the case member. Thus, it is possible to relieve the damage to the flat display device due to an external impact.

Abstract: A spring module includes: a resilient member having a pair of wire parts extending side by side along an axial direction and a connecting part connecting the wire parts at ends of the wire parts; and fastening members provided at opposite ends of the resilient member, respectively, wherein the resilient member provides a resilient force, which is applied in a direction which is inclined from the axial direction if the fastening members are positioned so as to be inclined away the axial direction, the resilient member being deformed as the fastening members move closer to or further away from each other.

Abstract: A sliding module for a slide-type portable communication apparatus including a main body and a sliding body which slides on the main body along a sliding distance provided from a start position to an end position. The sliding module includes a fixed plate engaged with the main body, a moving plate being engaged with the sliding body and sliding along the sliding distance. A sliding module is provided between the fixed plate and the moving plate and provides a dead point position between the start position and a center position of the sliding distance, or closer to the start position to slide the moving plate. The dead position prevents the accidental closing of the sliding body and loss of communication if a user's hand slips during the opening of the sliding body to expose a portion of the main body.

Abstract: A guide device for a sliding unit in a mobile terminal is provided. The guide device includes a lower slide including latch portions formed to open outwards, guide rails manufactured independently to be assembled with the latch portions, wherein the guide rails are disposed to extend in a longitudinal direction of the lower slide, and a guide plate comprising rack portions coupled with the guide rails, wherein the guide plate is disposed to face the lower slide.

Abstract: The present disclosure provides a damping device for a transverse sliding-type portable terminal includes a body, a sliding body, a sliding guide module configured to transversely guide the sliding of the sliding body on the body, wherein the damping device is installed at a central portion of a front circumference of the sliding body to minimize friction during an opening/closing operation of the sliding body with respect to the body.

Abstract: A sliding module for a sliding-type portable communication device, in which sliding members are integrally formed on both sides of a sliding housing. The sliding module for a sliding-type portable communication device preferably includes a body housing and a sliding housing sliding while facing the body housing, and a sliding guide portion provided in the body housing. The sliding guide portion includes guide members integrally formed on both sides of the guide portion and sliding members integrally formed on both sides of the sliding housing to be slidably coupled with the guide members.

Abstract: A sliding module includes a main member, a sliding member for sliding in engagement with the main member, guide members formed at both ends of the main member, and guide rails slidably engaged with the guide rails in a portable communication device, in which a contact engagement portion is provided at a guide member, a rail contact portion is provided at a guide rail, and a sheet portion is provided at the contact engagement portion to slidably engage the guide rail with the rail contact portion.

Abstract: A sliding-type portable terminal including a first housing, a second housing assembled with the first housing in such that the second housing is linearly movable relative to the first housing while being in contact with the first housing. The second housing is formed of a front case and a rear case, and sliding rails are assembled with inner surfaces on both sides of the rear case, respectively. A sliding guide is arranged on the first housing, and includes first guide grooves slidably holding both sides of the rear case. Second guide grooves extend with the first guide grooves in parallel and slidably holding the sliding rails, respectively. The portable terminal restricts unnecessary movement of the second housing relative to the first housing, and achieve smooth sliding of the housings.

Abstract: A sliding-type portable terminal is provided. The sliding-type portable terminal includes a first housing, a second housing sliding in a longitudinal direction of the first housing while facing the first housing, and an elastic member including a helical coil and free ends. The free ends extend from the coil in a direction away from each other and the elastic member provides an elastic force in a direction to move the free ends away from each other, in which the coil is interposed between the first housing and the second housing. An end of one of the free ends is rotatably supported on a first face of the first housing, and another of the free ends is extended toward the inside of the second housing and rotatably supported on an inner surface of the second housing. The sliding-type portable terminal has an advantage in that each of the free ends is located in one of the housings, by which the thickness of the terminal can be easily reduced and a space for a flexible printed circuit is easily ensured.
