The document reading and conveying unit includes a controller configured to perform pickup initialization of returning a pickup roller to an initial position after the completion of conveying one or more documents and is supported by the pressure plate. The controller includes a first timer configured to measure an elapsed time from the completion of reading performed by the fixed reader. The controller performs the pickup initialization after a measurement value measured by the first timer exceeds a first time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image reading apparatus","description":"An image reading apparatus includes a document reading and conveying unit, a pressing plate capable of moving to a position to press a document against a reading surface and to a position withdrawn fr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8477391","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.
