ーダ。One or more light emitting elements are placed along the rotation axis direction on either the outside or inside of the cylinder across the wall surface of a rotatable hollow cylinder, and one light emitting element is placed on the other side along the rotation axis direction. Alternatively, by arranging a plurality of light receiving elements and rotating the cylinder, one or more light rays from each light emitting element to each light receiving element are formed on the circumferential wall surface of the cylinder. A rotary fist encoder characterized in that an on/off encoded output representing the amount of rotation is obtained by intermittent striped patterns of transparent parts and opaque parts.
