Each non-transmitting part has a plurality of projecting parts which are arranged side by side in the circumferential direction. Each projecting part has a pair of reflecting surfaces which retro reflect incident light toward a light emitting part. A plurality of tracks include a periodic track where transmitting parts and non-transmitting parts are arranged with a periodic pattern and non-periodic tracks where transmitting parts and non-transmitting parts are arranged in a non-periodic pattern. The periodic track and non-periodic track are respectively arranged at positions in the radial direction where further reflected light at the light emitting part after retro reflection at the reflecting surfaces of the non-periodic track will not enter the periodic track."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rotary encoder having periodic and non-periodic tracks","description":"In a rotary encoder of the present invention, each track of a rotary disk has transmitting parts and non-transmitting parts alternately arranged in the circumferential direction.
