Abstract

PURPOSE: To obtain the coordinate input signal of excellent quality, by counting the delay time between the contact time point and the detection time point for change in the surface waves when the countact object is in contact with at arbitrary one point on the delivery line and by outputting the coordinate signal from the corresponding system between the delay time and the coordinate.
