The control unit moves the carriage to a first position at which the white reference member is provided, cause the reading unit to read the white reference member, moves the carriage to a second position that is an acceleration start position for accelerating toward the reading start position of the document positioning plate, and waits for a reading start instruction input from the input unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Document reading apparatus","description":"A document reading apparatus includes a document positioning plate configured to position a document, a carriage configured to move a light source along the document positioning plate, a reading unit ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8503049","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.
