Abstract:
1. A portable terminal comprising: a main body; a display unit rotatably mounted on the main body for displaying information; a sliding means for moving the display unit in a direction along a length of the portable terminal; and a rotating means mounted between the main body and the display unit for supporting the display unit to be angularly rotated along a plane of the main body, the rotating means configured to fix the display unit at one of a plurality of rotational positions including at least three different rotational positions within a range of 0°-90°, wherein the sliding means comprises: a guide groove formed on a surface of the main body in a direction along the length of the main body; sliding grooves formed on side walls of the guide groove; sliding protrusions formed at sides of the rotating means and movably inserted into the sliding grooves; and a removable unit for fixing the sliding protrusions in a set position, and wherein the rotating means comprises: a base unit coupled to the main body; a cylindrical axis unit formed at a surface of the base unit; a cam holder coupled to the display unit; a cylinder unit formed at the cam holder, the cylinder unit having an inside diameter that is larger than an outer diameter of the cylindrical axis unit, wherein the cam holder comprises a mounting unit formed at an outer circumference of the cylinder unit; a through hole formed at the base unit, through which wire for coupling the display unit and the main body passes and extends to a hollow portion of the cylindrical axis unit; a position fixing protrusion unit formed at the base unit; a cam unit formed at an end of the cylinder unit, the cam unit having a plurality of concave and convex parts and allowing the display unit to stop at the plurality of rotational positions by engaging the position fixing protrusion unit; pressuring means inserted into the mounting unit for pressuring the cam holder to the base unit; and a fixing member fixedly coupled to an end of the cylindrical axis unit and inserted into the cylinder unit for supporting the pressuring means, wherein the fixing member is fixed at an outer circumference of the cylindrical axis unit.
