Abstract:
1. A hinge apparatus enabling two-axis rotation of a first housing and second housing of a portable terminal, comprising: a pair of side hinge arms extending from the first housing of the portable terminal; a hinge housing coupled between the pair of side hinge arms to enable rotation around a first hinge axis; a coupling shaft fixed to the hinge housing, the coupling shaft extending along a second hinge axis perpendicular to the first hinge axis; a coupling member coupled to the second housing of the portable terminal, and further coupled to the coupling shaft to enable rotation around the second hinge axis; and a cam member disposed at least partially within the hinge housing moveable on the coupling shaft along the second hinge axis, wherein rotation of the portable terminal along the first hinge axis causes the first housing and second housing to transition from a folded state to an open state, and rotation of the portable terminal along the second hinge axis causes a pivot such that a first surface and second surface of the second housing is reversed relative to the first housing.
