A display unit is provided with a touch panel (contact-position detecting device) on the image display screen of the display unit and is used by inverting (0 and 180 degrees) or rotating (opening/closing state) the image display screen. An orientation detecting device is provided for detecting the orientation of the display unit. A table is provided for storing relationships between the coordinate positions of the touch panel and predetermined processing. When a predetermined operating part of the touch panel is touched, it is transformed into a coordinate position of the touch panel, and the predetermined processing corresponding to this coordinate position is performed. |
