Patent ID: 8437146

Claim:
A portable terminal comprising: a first housing; a second housing coupled to the first housing via a hinge device, the second housing pivoting about a first axis toward or away from the first housing to be closed or opened and rotating about a second axis, the second axis extending perpendicular to the first axis; and the hinge device including: a hinge housing extending along the direction of the first axis and coupled to the first housing in such a manner that the hinge housing is rotated about the first hinge axis on the first housing; a coupling member anchored to the second housing and coupled to the hinge housing to be rotatable about the second axis, wherein while the hinge housing is being rotated about the first hinge axis, the coupling member rotates around the first hinge axis in a state in which one side of the coupling member is in contact with an outer peripheral surface of the hinge housing; a coupling shaft extending along a direction of the second hinge axis and having one end fastened to the hinge housing, and an anchoring member anchored to the other end of the coupling shaft, the anchoring member being anchored to be faced to the other side of the coupling member in a state in which the coupling shaft extends through the opposite sides of the coupling member, thus allowing the coupling member to be tied to the coupling shaft; a cam member received within the hinge housing for reciprocating in the direction of the second hinge axis, the coupling shaft extending through the cam member; and one or more elastic members, which are supported by the inner wall of the hinge housing and the cam member in such a manner that the elastic members force the cam member against the coupling member.
