The controller determines a first size of the document sheet in a main scanning direction. The controller determines a second size of the document sheet in a sub scanning direction on the basis of the sets of first data. The controller determines a reading range on the basis of the first and second sizes. The reading section reads the determined reading range on the line-to-line basis to obtain an image of the document sheet."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image reader having document detector for detecting presence or absence of document sheet to determine reading range","description":"In an image reader, a controller control, during a period from a timing when a detector detects an open state of a cover to a timing when the detector detects a closed state of the cover, a document d","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9832332","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.
