Abstract

PURPOSE:To provide a detector for physical quantities of a body of revolution, in which the variations of the physical quantities of the body are detected so that the detected signals may be transmitted from a rotary portion to a stationary portion without any contact by means of an optical coupling using a light emission element and a photoelectric element.
