The present invention relates to an apparatus for opening and closing a cover of a cellular phone in which a slide module capable of slidably opening and closing a cover of a cellular phone is constructed in a structure of using an elastic force of a spring, so that it is possible to precisely recognize an opening and closing operation of a cover, and an opening and closing operation of a cover is efficiently achieved. The apparatus includes a body having a keypad, a cover being engaged to the body slidably in forward and backward directions and having a display panel, an upper plate engaged to a lower side of the cover, a lower plate engaged to an upper side of the body, wherein the upper plate is slidably engaged to the lower plate, a rotation plate rotatably engaged between the upper and lower plates and adapted to slidably move the upper plate in forward and backward directions with respect to the lower plate, an elastic support unit having one end fixed to the rotation plate and the other end movably supported by an upper surface of the lower plate, wherein the elastic support unit is adapted to elastically support the rotation plate when the upper plate is slidably moved, and a stopper unit provided in the upper and lower plates and adapted to limit a slidable movement of the upper plate with respect to the lower plate.

In a mechanism which relatively slides a first casing and a second casing of a portable terminal device in a state that the casings are laid over each other in a vertical direction, in order to attain a slide mechanism which is simply structured and structured to enable open / close operation of the first casing and the second casing to be automatically conducted from predetermined slide positions of the both casings, the mechanism relatively slides the first casing and the second casing in the state that the casings are laid over each other in the vertical direction, and is constituted with: a base member mounted on either one of the first casing and the second casing; a slider slidably mounted on the base member and mounted on the other one of the first casing and the second casing; and a resilient means, which is disposed between the slider and the base member, for slidably biasing the slider in a closing direction and / or an opening direction from predetermined slide positions, by being displaced according to a slide position of the slider. Meanwhile, the resilient means is a torsion spring and the torsion spring is mounted so that a direction of action of resilience thereof is displaced according to slide operation of the slider, by one end side of the torsion spring being pivotally supported on the base member and the other end side being pivotally supported on the slider.

A system for operating a gate of a vehicle may include a laser diode unit that shows step positions for operating the gate by radiating a plurality of laser points onto the ground, an ultrasonic wave sensor unit that measures the distance between the bottom of the rear bumper and the step positions and senses step input from a change in the distance due to the user stepping on the step positions, a gate driving unit that opens / closes the gate, using a driving part, and a control unit that controls the opening / closing operation of the gate driving unit on the basis of information on a step-on status kept for a predetermined time by the user which may be found by the ultrasonic wave sensor unit.
