| 20080204985 | PORTABLE TERMINAL WITH HINGE APPARATUS - A portable terminal having a hinge apparatus is provided. The portable terminal includes a first housing, a second housing pivotally coupled to the first housing so that the second housing can be unfolded from and folded onto the first housing, and a hinge apparatus coupling the first housing and the second housing together. The hinge apparatus provides a first hinge axis and a second hinge axis perpendicular to each other, in which, from the folded state in which the second housing is folded on the first housing, the second housing is operable to rotate about the first hinge axis to be located in an upper side of the first housing and to rotate about the second hinge axis to be located in a first side of the first housing. Also, the hinge apparatus allows the second housing to rotate about the first hinge axis to be unfolded at an angle of approximately 90° with respect to the first housing and then rotate about the second hinge axis so that an inner face of the second housing is oriented in a same direction in which a first side of the portable terminal faces. Therefore, the hinge apparatus provides a portable terminal that is convenient to use not only communication functions, but also multimedia services such as watching broadcastings. | 08-28-2008 |
