A portable terminal includes: a first housing; a second housing rotatably connected to the first housing to open or close the housings. A hinge device interconnects the first and second housings. The hinge device provides first and second hinge axes extending perpendicular to each other, wherein the hinge device limits the rotation of the second housing about the second hinge axis when the second housing has been rotated about the hinge axis to the open position, and the hinge device limits the rotation of the second housing about the first hinge axis when the second housing has been rotated to the open position. The portable terminal with the inventive dual axis hinge device is configured in such a way that one housing can be positioned at the top side or lateral side of the other housing, whereby it is convenient to use the portable terminal and it is possible to secure structural stability and reliability.
