Abstract

The present invention relates to a slide type portable terminal and methods for the same. Embodiments of a slide type portable terminal can include a main unit having key sections that are formed on a surface of the main unit, a slide unit that can slide relative to the surface of the main unit to cause each of the plurality of the key sections of the main unit to be covered and exposed and a slide driving mechanism for causing the slide unit to slide, for example, using restorative forces. The slide mechanism can include coil springs guided by guide bars. The guide bars can have both ends rotatably coupled to the main and slide units, respectively, such that the lengths of portions of the guide bars can change as the slide unit is moved.
