Abstract: A triple-axis rotation folder-type portable apparatus includes a main body having first and second regions positioned on the top surface thereof, the second region being adjacent to the first region; a folder adapted to rotate a first rotation angle about a first hinge axis from a state in which it faces the main body, to rotate a second rotation angle about a second hinge axis while being deflected which is perpendicular to the first hinge axis in such a manner that the top and bottom surfaces thereof are inverted, and to rotate a third rotation angle about a third hinge axis which is coaxial with the first hinge axis in such a manner that the top and bottom surfaces thereof are inverted to face and hide the first region while exposing the second region; and a hinge device for connecting the folder to the main body in such a manner that the folder can rotate about the first, second, and third hinge axes.
