PROBLEM TO BE SOLVED: To improve accuracy in the detection of a pressed position on a touch panel. SOLUTION: The functions or the like of a plurality of operation keys or equipment connected to equipment for performing input operation to the equipment are displayed on a display part, the touch panel is provided while being overlapped on the display part and corresponding to the pressed position on the display part, the input operation to the equipment can be recognized by this touch panel. By dividing the touch panel into prescribed number of parts by a dividing means, an output voltage signal to the pressed position is divided into arbitrary detection units (divided units) and the orthogonal parts of respective divided units in X and Y directions are recognized and determined as a final position of the pressed position. Besides, a number of divisions divided by the dividing means is changed by a division number change means. The division number change means can suitably change the number of divisions while considering the size of operation keys, the thickness of finger of a user and impressed voltage or the like. |
