Abstract
In a resistance film tablet system which includes a pair of resistance films superposed on each other and spaced by a predetermined distance therebetween, a value measured at the previous detection is stored in a memory beforehand and is read out for being converted into an analog voltage, then, a capacitance portion of the resistance films is charged with the voltage. The capacitance portion is converged to its convergent value faster, thereby a faster sampling can be operated. It is therefore possible to scan a resistance film tablet system faster by shortening a waiting time after a necessary mode setting, when measuring a voltage at a contact point in X-detection or Y-detection mode.
