Abstract
A hinge device for a portable wireless terminal with a first housing and a second housing being rotatably connected to the first housing is provided, comprising a double hinge arm rotatably connected respectively to the first and second housings and a pair of hinge modules for stopping the rotation of the double hinge arm at various angles. The hinge device includes a pair of rotary axes, allowing one selected housing to be rotated about the other housing by 360°. A portable wireless terminal employing the hinge device can accommodate various units such as a display device, an inputting unit, among others, and the functions of the terminal are easily modified and extended. Furthermore, various information terminals are easily integrated as a single portable wireless terminal. Moreover, since a user can open or close the terminal at various angles, a portable wireless terminal employing the hinges is convenient to use.
