PROBLEM TO BE SOLVED: To solve the problem in foldable information processor, including a portable telephone unit and a notebook computer, such that key input is not possible when the case is closed, because the operation buttons including a ten key are disposed inside the case, and that only auxiliary key input is possible in case of the equipment having operation buttons disposed on a side face of the case. SOLUTION: On an outer face of the case of the foldable information processor, a display means are disposed to display soft keys, and on a side face of the case, operation keys corresponding to the soft keys are disposed, so as to enable key input. With the above configuration, soft keys can be used even when the case is closed. Also, when the operation keys being disposed on the side face of the case are positioned substantially far from the display position of the soft keys, positions of the operation keys are displayed near the soft keys, thus improving easiness to use.
