PROBLEM TO BE SOLVED: To easily operate an operation part while viewing a display part even in a horizontal state by enlarging the display part while suppressing the whole size and allowing users to simply switch the display part to a vertical state or the horizontal state. SOLUTION: A second housing 5 provided with the operation part and a first housing 3 are connected with a hinge part 6 so as to be foldable. When a liquid crystal display part 2 (the display part) is switched to the vertical state or the horizontal state, a cam mechanism 10 supports and guides the display part so that its lower edge side conrner part moves along the hinge part 6. While the liquid crystal display part 2 is in the horizontal state, electronic mail sentences may be displayed on the liquid crystal display part 2. COPYRIGHT: (C)2008,JPO&INPIT
