The movable unit rotates with rotation of the rotatable member so that the second light-blocking surface is movable to a first position where the optical detecting device is light-blocked and a second position where the optical detecting device is not light-blocked, and includes a locking member for locking the second light-blocking surface in the second position. When the first and second light-blocking surfaces pass through a detecting portion of the optical detecting device, the control unit discriminates a state of the movable unit on the basis of a detection result of the optical detecting device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image forming apparatus","description":"An image forming apparatus includes an optical detecting device; a movable unit including a rotatable member having a first light-blocking surface and a second light-blocking surface; and a control un","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9719810","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.
