Claim:
A mobile phone comprising: a first housing; a second housing; and a dual connection member comprising: a first connection member for rotatably interconnecting the first housing and the second housing in such a manner that the second housing is rotatable about a first hinge axis toward or away from the first housing; a second connection member comprising first guide means and providing a second hinge axis which is eccentrically positioned from the center of the second housing, wherein the second housing is connected to the dual connection member substantially by the second connection member such that the second housing is rotatable about the second hinge axis, and the first guide means allows the second hinge axis to be slid towards and away from the first connection member according to a degree of rotation of the second housing; and a third connection member comprising second guide means and providing a third hinge axis which is eccentrically positioned from the center of the first housing, wherein the first housing is connected to the dual connection member substantially by the third connection member in such a manner that the first housing is rotatable about the third hinge axis, and the second guide means allows the third hinge axis to be slid towards and away from the first connection member according to a degree of rotation of the first housing, wherein the first and second housings are connected respectively to the third and second connection members while being rotatable about the third and second hinge axes, respectively, wherein the third and second hinge axes extend perpendicular to the front and rear faces of the first and second housings and are eccentrically positioned in relation to centers of the first and second housings, respectively, and the dual connection member causes the third and second hinge axes to be slid as the first and second housings are rotated, and wherein the first and second guide means each comprise a guide rail slidably gripping outsides of a plurality of guide bars parallel mounted on opposite sides of a guide member, and the first and second guide means each further comprise a structure of a pin in a slot, wherein a shape of the slot determines a path and range of motion of at least one of the first housing and the second housing.
