Abstract

PURPOSE:To secure a proportional relation between the difference of phase and the coordinates and thus reduce the error of measurement, by providing plural weighted apertures to a flat plate type resistor and causing a change to the distribution of resistance. CONSTITUTION:Plural apertures 10 are provided to a register 1' used in the X and Y directions for an AC pattern input device, and the slope of resistance is set large at the circumference area and small at the center part respectively. As a result, a uniform distribution of phase is ensured, and a proportional relation is secured like a straight line B between the coordinates X and phase phi. This reduces the error of measurement.
