<p>PROBLEM TO BE SOLVED: To detect the presence of plural pressed spots on a touch panel. SOLUTION: A touch panel 1 is composed of a pair of resistance films 11 and 12 arranged while facing. The resistance film 11 is deformed by pressing and contacted to the resistance film 12 at the deformed part. A coordinate detecting circuit 24 repeatedly detects the coordinate of a contact position between the resistance films 11 and 12 and measures time from the detection of the coordinate of the contact position to the detection of a coordinate different from this coordinate. When the measured time is shorter than prescribed time, the coordinate detecting circuit 24 judges the presence of plural pressed spots on the touch panel 1.</p> |
