The supporting unit has a pair of receiving members that support the imaging unit, in a sub-scanning direction, near both ends, as seen in a main scanning direction, of the imaging unit. The optical scanning apparatus also has; a bend-adjustment unit that corrects bend. The bend-adjustment unit is disposed on the supporting unit at a plurality of positions along the main scanning direction. The optical scanning apparatus further has a free-sliding unit for securing free expansion of the imaging unit due to temperature changes thereof."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical scanning and image forming apparatus with a free-sliding unit for thermal expansion","description":"An optical scanning apparatus has: a deflection unit that scans beams emitted from a plurality of laser light sources; an imaging unit having one or more optical elements for imaging beams scanned by ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8508808","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.
