PURPOSE: A hinge device for a portable terminal having a multi-angle hinge cam is provided to offer convenience to a user by stopping a folder at various angles according to an eyes angle of the user. CONSTITUTION: A hinge cam(33) is formed as a pair of protrusions(331,332) opposite with one end having a guide axis(334) on an axis and a slot portion(333) caved between the protrusions(331,332). Sliding surfaces(331a,331c,332a,332c) slanted at a certain angle and slant surfaces(331b,332b) slated at a certain angle are formed at both sides of a pair of protrusions(331,332). A guide asperity is formed on one between a pair of protrusions(331,332). When a folder is rotated, a mount shape portion of a hinge shaft and the slant surfaces(331b,332b) of the hinge cam(33) are contacted and the folder is stopped at a random angle. |
