When the dynamic code disc rotates by a certain angle, the center of the light source tube, the center of the static code disc, a reading point of a signal recording region of the dynamic code disc, and the center of an optoelectronic signal reception chip on the circuit board are located in a same straight line. The light source tube, the static code disc, the dynamic code disc, and the circuit board are arranged sequentially at intervals along the direction apart away from a body. The optoelectronic signal reception chip on the circuit board is arranged at the side close to the dynamic code disc. An accommodating hole is formed on the inner side surface of the body, and the light source tube is arranged in the accommodating hole. Multiple bosses supporting and fixing the static code disc are formed on the inner surface of the body and distributed uniformly around the accommodating hole in a ring shape. The static code disc and the end surfaces of the bosses are connected by glue. The rotary encoder is reasonable in structure and relatively high in precision.
