<P>PROBLEM TO BE SOLVED: To improve operability and visibility by exposing the entire surface of a second casing in a horizontally opened state in a foldable mobile terminal having three rotary shafts. Ž<P>SOLUTION: A first casing 3 includes a first rotary shaft 10 rotating to be freely inverted to the front and back to a hinge part 6. A second rotary shaft 11 which is extended in the longitudinal direction of a second casing 5 and rotating the hinge part 6 centering on the longitudinal direction of the second casing 5 is provided in the second rotary shaft housing part 5b of the second casing 5. The hinge part 6 includes a third rotary shaft 12 orthogonal to the first rotary shaft 10. A closed state wherein the first casing 3 and the second casing 5 are folded and piled up, a vertically opened state wherein the first casing 3 is opened to the second casing 5 centering on the third rotary shaft 12, and the horizontally opened state wherein the first casing 3 is opened to the second casing 5 together with the hinge part 6 centering on the second rotary shaft 11 is switched. In the horizontally opened state, the right side face 3a of the first casing 3 is positioned below the right side face 5d of the second casing 5. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
