ABSTRACT:
A portable terminal is provided. The portable terminal includes first, second and third housings. The second housing is rotatably engaged with one portion of the first housing. The third housing has one end engaged to linearly move closely beneath the rear surface of the second housing and the other end rotatably engaged with the other portion of the first housing. The third housing is folded onto the first housing, interposed between the first housing and the second housing, and when the second housing and the third housing rotate away from the first housing, the first, second and third housings form a triangular prism.
