<p>PROBLEM TO BE SOLVED: To provide an inexpensive and accurate control panel which includes a simple parts lattices and its control circuit. SOLUTION: This control panel is provided with an analog touch panel 101, the switching means 104a to 104e and 105 which switch the signals supplied between the terminals of the panel 101 and/or the supervisory signals, a detection means 106 which detects the signals at the terminals of the panel 101, a coordinate calculation means 107 which calculates the coordinates of a depressed point, based on the signals detected by the means 106, the display means 102 and 103 which are placed under the panel 101, and a control means 107 which carries out a detection/calculation process as a routine process to detect the depressed state of the panel 101 in a 1st prescribed cycle and to calculate the coordinate value of the depressed position and also carries out an interrupt process that is executed in a 2nd prescribed cycle shorter than the 1st one as a background process that is independent of the said detection/ calculation process.</p> |
