Abstract
In a personal data assistant, a main body includes an input sheet, which is turnable between a first position where at least a part of a display unit of the personal data assistant is covered and a second position where the display unit is not covered. The input sheet has various types of keys formed thereon. When any one of the keys is pressed on the input sheet, a pressure is applied to an input device formed on the display unit, and an input coordinate is detected by the change of, for example, the resistance value of the input device. Since the surface of the display unit is not entirely covered with the input sheet, the display in the range of the display unit which is not covered with the input sheet is not made dark. Further, since the input device is not directly touched with a finger, the input device is prevented from being made dirty, and the display of the display unit under the input device is prevented from being difficult to be seen. Accordingly, the operability of the personal data assistant can be improved while displaying information clearly.
