HINGE APPARATUS FOR PORTABLE TERMINAL

摘要

A hinge device of a portable terminal is provided to decrease the damage to the external appearance of a housing and implement the opening of the portable terminal by a simple operation of a button. A first hinge cam(101) is extended to a longitudinal direction and has a cylindrical shape. The first hinge cam includes a first corn-shaped part(111), a linear protrusion(113), and a rotation guide. A second hinge cam is received in the first hinge cam. The second hinge cam includes a second corn-shaped part(121), an insertion hole(123), and a protrusion(125). The second corn-shaped part is adjacent to the first corn shaped part. The protrusion is geared with an inner side of the first hinge cam. The second hinge cam is linearly moved inside the first hinge cam. An elastic member(104) is positioned in the other side of a rotation cam(103). The elastic member maintains the stop state of the rotation cam by providing the elastic force to the rotation cam.
