<p>PROBLEM TO BE SOLVED: To realize the equivalent functions of the left key and the right key of a mouse device without the need of an external device, to execute the two operations of coordinate input and instruction input only by means of a finger or the like, to miniaturized and simplify a touch panel device and to improve operability. SOLUTION: When a piezoelectric sensor 6 arranged on a touch panel part 2 is depressed, a potential difference occurs is a pertinent part. Since the size of the finger is larger compared to the arrangement interval of the piezoelectric sensor 6, voltage is generated in the plural adjacent piezoelectric sensors, and the signal is transmitted to a position arithmetic unit 3 and a pressure distribution judgment unit 4. The position arithmetic unit 3 calculates position information according to from which piezoelectric sensor the signal arrives. The pressure distribution judgment unit 4 compares output voltages from the plural adjacent piezoelectric sensors, and judges whether voltage distribution is normal distribution or deflection distribution of either one side or the other side. There position information and the distribution in formation are transmitted to pseudo mouse control driver software 5.</p> |
