The imaging optical system includes: a first optical element, arranged inside a first lens barrel, and having an optical surface that is rotationally symmetric about an optical axis; and a second optical element, arranged on an optical path between the first lens barrel and the photoelectric conversion element, and having an optical surface rotationally asymmetric about the optical axis. The alignment method includes aligning at least one of an attaching angle and an attaching position of the second optical element in a sub scanning direction relative to the first lens barrel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Alignment method for an image reading apparatus","description":"Provided is an alignment method for an image reading apparatus including: a light source unit illuminating an original on an original table; a photoelectric conversion element for converting an optica","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8514384","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.
