Abstract:
1. A portable terminal comprising: a first housing; a second housing rotatably connected to the first housing to be capable of being moved between an open and closed position with respect to the first housing; and a hinge device interconnecting the first and second housings, the hinge device providing first and second hinge axes extending perpendicular to each other, the hinge device comprising: a first hinge base fixed to the first housing; a second hinge base extending in a direction of the first hinge axis and connected to the first hinge base so that the second hinge base is rotatable about the first hinge axis with respect to the first hinge base; and a second connection shaft connected to the second hinge base so that the second connection shaft is rotatable about the second hinge axis, and wherein the second housing is fixed to the second connection shaft, so that as the second hinge base rotates, the second housing is rotated about the first hinge axis to the open position, and as the second connection shaft rotates, the second housing is rotated about the second hinge axis to the open position; and wherein the hinge device prevents the rotation of the second housing about the second hinge axis when the second housing has been rotated about the first hinge axis to the open position, and the hinge device prevents the rotation of the second housing about the first hinge axis when the second housing has been rotated about the second hinge axis to the open position.
