Abstract
Abstract In an information input device for inputting information in an information processing apparatus by means of contact on an input surface provided on a display picture, an input-prohibiting area is provided on the input surface in response to setting a cleaning mode of the input surface, and the input-prohibiting area and an input-enabling area are discriminately displayed. At the same time, the brightness of the input surface is made high during the cleaning mode.
