The lens drive unit is provided with a position detection unit that is disposed with an intervening space on the image formation side of the autofocus movable unit in the direction of the optical axis and that is for emitting light toward the autofocus movable unit, receiving reflected light that has been reflected by the autofocus movable unit, and detecting the position of the autofocus movable unit in the direction of the optical axis on the basis of the received light intensity. Part of the member displaced along with the autofocus movable unit functions as a reflective plate for reflecting light emitted from the position detection unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lens drive device, camera module, and camera-mounting device","description":"Provided is a lens drive device that, using drive force from a voice coil motor, automatically carries out focusing by moving an autofocus movable unit with respect to an autofocus fixed unit in the d","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10495844","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.
