Claim:
A mobile communication terminal comprising: a first body having a display unit; a second body; a connecting part connecting the first and second bodies together to enable the first and second bodies to rotate on a prescribed axis; and a control unit arranged to change a function according to a rotation angle and a rotation direction between the first and second bodies, and to display an image corresponding to the changed function on the display unit, wherein the connecting part comprises a 4-way connector system configured to enable the first and second bodies to mutually rotate and change the function, wherein the 4-way connector system provides four connectors to a 4-way cross section to change a contact point relative to the rotation of the first and second bodies, wherein correspondent faces of the connected first and second bodies are configured as an equal sized equilateral polygon, wherein a plurality of different input units are provided on exposed faces of the second body, wherein a different function corresponds to each of a plurality of relative rotation angles and rotation directions between the first and second bodies, wherein the different function corresponding to each of the plurality of relative rotation angles and rotation directions is activated when the first body is flush with the second body, and wherein the first body and second body may each be rotated to at least four positions.
