Abstract

PURPOSE: To make it possible to accomplish the highly precise detection of a rotational speed with the use of a simple construction by arranging a magnet in the vicinity of the circumference of a turntable and by adding a servomechanism to the magnet to minimize the dislocation due to the dislocation detecting signal.
