ABSTRACT:
A display/input device is constituted by superposing a display device and a transparent tablet on each other. An operator points an icon included in an image displayed on a screen of the display device by means of a stylus pen, thereby inputting data. A central part of a coordinate detection area of the tablet overlaps the screen of the display device, and a peripheral part of the coordinate detection area is situated outside the screen. When the stylus pen points a predetermined region within the peripheral part of the coordinate detection area, predetermined processing ("cancel", "previous page", "next page") corresponding to a command allocated to the pointed predetermined region is carried out.
