<p><P>PROBLEM TO BE SOLVED: To provide a touch panel input device, capable of changing the size of an operation key while preventing a display range of display content from being extremely reduced. <P>SOLUTION: The operation key is displayed in a standard size until depression to a touch panel 1 is detected first. When a depression range detected thereafter is larger, compared with a depression range preliminarily associated with the operation key of the standard size, the size of the operation key is changed to be larger than the standard size. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
