<p>PURPOSE:To prevent erroneous input and improve operability by eliminating an invalid area in an extended definition area and providing invalid areas between definition areas. CONSTITUTION:Plural large and small definition areas KS, LKS are formed in an information sheet 14. Out of these, KS represents a definition area equal in size with a key area Z, and LKS represents an extended definition area extending over plural adjoining key areas Z. These definition areas KS, LKS are so arranged that boundaries between them are positioned on X electrode line or Y electrode line and at least one intersection of X, Y electrode lines is positioned in the area. Thus, even in the area KS of smallest size, one intersection of X, Y electrode lines always present in the area. At the same time, X electrode line or Y electrode line is always provided at the boundary between areas KS, LKS.</p> |
