The irradiation device includes a reflection board configured to rotate and to focus the light from the light source by its rotation and reflect the focused light onto a manuscript. The irradiation device is configured to irradiate uniformly the manuscript with both the light source and the reflection board when the manuscript is scanned, and to irradiate the white reference board from only one oblique direction with the light source before white reference data are generated from the white reference board."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image scanning device","description":"An image scanning device comprises a white reference board having a uniform white color; an irradiation device including a light source unit having a light source, the light source unit configured to ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8467108","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.
