Abstract

PURPOSE:To convert rotation of a rotating disc revolving the same number of revolutions as a rotary body to a signal of a frequency corresponding to the rotary speed by a plurality of detectors and operating the voltage sum in a plural series of circuits whereby the accuracy of measurement is improved regardless of the eccentricity of the rotating member.
