Abstract: A portable terminal includes a first housing (1) having a display unit (3), and a second housing (2) having a first and a second operation unit (4a, 4b) located on the respective sides thereof, rotatably connected about a rotation shaft (5) located generally at a center of the housings, and the first housing (1) and the second housing (2) are generally the same in size. Such structure allows hiding the second housing (2) when carrying the portable terminal or when complicated manipulation is not required, thereby enabling reducing the overall size of the portable terminal, yet providing a large screen on the first housing (1). Rotating the housings enables using the operation unit at two separate locations, the first and the second operation unit (4a, 4b) on the second housing (2), or three separate locations including an auxiliary operation unit (3a) on the first housing (1) and the first and the second operation unit (4a, 4b), thus permitting using both hands to hold and manipulate the portable terminal.
