<p>PURPOSE:To improve linearity by permitting a control signal group to fetch each coordinate signal so as to store a correction equation and calculating a real coordinate value from said stored signal at the time of an actual input. CONSTITUTION:An input position detector is constructed of the 1st parallel electrode group 4 composed of plural electrodes, an insulating substrate equipped with the 1st resistance 5, an insulating substrate with a constitution similar to the former substrate and a voltage-sensitive sensor 3 installed between both substrates. In order to correct an input position coordinate signal, the 1st read group 8 pulled out of the 1st parallel electrode group 4 at the same interval, the 2nd read group 9 pulled out of the 2nd parallel electrode group 6 in the same manner and a coordinate signal generating switch group 10 connected in correspondence to said groups are provided. The switch group 10 is controlled on and off by a control signal group 11. Thus, prior to entering in a use mode, the switch group 10 is turned on and off to fetch an initial value. Then the correction equation regarding coordinates X and Y is stored, and corrects and calculates the signal at the time of an actual input so as to output.</p> |
