The control unit causes the image reading unit to perform a reading operation for specifying the size of the document in the main scanning direction in a state in which the document cover is open, and causes the light source to emit a predetermined light amount in the reading operation, which is larger than the light amount when the document image is read from the document."},"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 according to the present disclosure includes: a platen glass on which a document is placed; a light source, an image sensor; an image reading unit for optically reading an i","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11283952","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.
