<p>PROBLEM TO BE SOLVED: To make a sensor, which individually identifies the switching of functions, and the like unnecessary and to reduce the cost of a pen input device by forming a prescribed command area at different position for every function switch sheet. SOLUTION: A sheet exchange key area 14 is an area which is pressed via a pen when another function switch sheet is placed on a main function switch sheet 9 against an opening part 5 of a tablet 10. A YES key area 145 is pressed via a pen when the sheet exchange is controlled and formed at a different position for every function switch sheet. Thus, the area 15 is turned on by a pen for every function switch sheet to turn on the different areas of the tablet 10 and every function switch sheet can be identified. In other words, the placing position of the area 15 differs according to function switch sheets and a sensor, etc., can be omitted. In such a constitution, both of the cost and size of the pen input device can be reduced.</p> |
