Abstract

A rotary-type hinge apparatus for a folder-type portable terminal is provided. For a portable terminal including a main body, a folder, a connection member for coupling the main body with the folder, and a hinge apparatus for rotatably coupling the connection member to the main body, a rotary-type hinge apparatus includes housing means mounted in the connection member, cam means including a center cam unit having at least three cam faces and a pair of side cam units for moving towards or away from the center cam unit according to the rotation of the folder in order to maintain close contact with selected cam faces, and adjusting the rotation angle of the folder by cam movement with the selected cam faces while being accommodated in the housing means, elastic bodies for causing the side cam units to closely contact the selected cam faces while being accommodated in the housing means, and an axis extending in a longitudinal direction of the center cam unit. Thus, the rotary-type hinge apparatus can allow users to conveniently view moving pictures.
