<p>PROBLEM TO BE SOLVED: To easily select and input a target process item by providing a sheet in which a processing function is entered in an area outside a display screen so that it can be replaced. SOLUTION: Icons 202 showing process items are printed at the upper edge part and left edge part of an icon sheet 201 made of a plastic film outside the liquid crystal display screen, and other parts are left transparent. More than one icon sheets 201 are prepared so that they are inserted into an icon sheet insertion slot 203 bored in the upper flank of a portable information terminal device 200 and used. A character, a symbol, or a process item is selectively inputted and displayed out by pressing the surface of the touch panel of an input/output device with a dedicated pen 205. An icon sheet is installed on the touch panel without disturbing a display on the liquid crystal surface screen so that it can be replaced, and can be used, so a target item can easily be selected out of many different process items to improve the usability.</p> |
