<p><P>PROBLEM TO BE SOLVED: To provide an optical touch panel device suppressing two point input unintended by a user, especially unintended two point input occurring by simultaneous contact of both a nail and a finger. <P>SOLUTION: In this input device using an optical touch panel detecting position coordinates by light shielding of a matrix-like optical axis formed by a light emitting element and a light receiving element forming a pair, when contact coordinates detected by the optical touch panel are two points and when the two points parallel move, only one point is output by deciding one-side coordinates as the nail to prevent the two point input unintended by the user. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
