体の移動量検知装置。[Claims for Utility Model Registration] (1) A photoreflector with a light emitting element and a light receiving element adjacent to each other is provided on a fixed body, and the light emitted from the light emitting element is reflected onto a moving body that moves relative to the fixed body. A pattern is provided in which reflective surfaces and non-reflective non-reflective surfaces are alternately and continuously formed, and a plurality of apertures are provided between the pattern and the photoreflector through which the projected light passes and the reflected light from the reflective surface passes. A device for detecting the amount of movement of a moving body, characterized in that a mask provided therein is disposed. (2) Claims for registration of a utility model characterized in that the reflective surface and the non-reflective surface of the pattern have the same width, and the opening width of the opening of the mask is approximately equal to the width of the reflective surface. The device for detecting the amount of movement of a moving object according to paragraph (1).
