Abstract

An automatic sliding module of a mobile terminal is provided to accomplish a high quality smooth operation preferred by a user, and allow a sliding operation manually in a power-off state. A guide shaft(33) for linearly guiding a moving slider hinge(32) that attaches upper and lower slider bodies(11,12) having an LCD(Liquid Crystal Display) and slidably moved is attached to a base slide hinge(31). A feeding motor assembly(40) is formed by integrally assembling a stepping motor(41), which operates upon receiving an electrical pulse signal and has a planetary gear, and a lead screw(42) coaxially rotated with the stepping motor(41). A lead gear(43) formed at the moving slide hinge(32) is combined to a slope face of the lead screw(42) which is rotated when the stepping motor(41) is driven, in order to convert the rotational movement of the lead screw(43) into a linear movement to allow the moving slider hinge(32) to slidably operate.
