Abstract
In a unit body of a portable information terminal is assembled a display and a pressure-sensitive input device overlying the display. An opening and closing cover is attached to the unit body for covering the pressure-sensitive input device. An operating button device provided in the cover exposes, when the cover is closed, its operating surface from the surface of the cover. The operating button device exerts a pressing force applied to the operating surface onto the surface of the pressure-sensitive input device. Thus, with the cover closed, major function entry or data entry can be carried out.
