The first major surface is also provided with a code pattern part which extends in a ring shape around the rotation axis at a position different from the incident part to switch transmission/non-transmission of the totally reflected light in accordance with a rotation position of the code plate. The code pattern part has nonplanar exit parts which transmit the totally reflected light, and planar secondary reflection parts which again totally reflect the totally reflected light. The secondary reflection parts and exit parts are alternately arranged in the circumferential direction about the rotation axis."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reflective type optical encoder","description":"A code plate of an optical encoder has a nonplanar incident part on a first major surface for transmitting light emitted from a light emitter to the inside of the code plate, and a planar primary refl","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9823096","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
