Abstract: A swing hinge device of a portable terminal has a pair of housings, which are coupled to each other in such a manner that they can be rotated while facing each other. Using a resilient means and a pair of cams, the swing hinge device provides a rotational force so that one of the housings can be rotated semi-automatically to a position for allowing speech communication. The device also uses a hinge stopper, stopper washer, and the like to limit the range of rotation of the housings to 360° or less in any direction. This avoids any damage to a flexible printed circuit board and the like, which is positioned between the pair of housings.
