Abstract
An arithmetic unit 212 is a correction filter 212a based on the relative displacement characteristics between a scale unit 19b and the end of a slider 16, and calculates a measured value by adding up together the displacement of the stylus tip 17a and a value found by applying the correction filter 212a to the displacement of the slider 16 detected by the scale unit 19b.
