The raisable/lowerable mirror covers a projection-light opening formed in the top surface of the housing and able to rotate with respect to the housing, and has a convex mirror on the inside surface thereof. The raisable/lowerable mirror covering the top surface of the housing forms a smoothly connected, smooth, convexly curved surface with no height difference between the edge of the raisable/lowerable mirror and the front edge of the opening, and a half-bowl-shaped concavity is formed on at least one side of the raisable/lowerable mirror in the direction of the axis of rotation thereof."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Projection video display device with raisable/lowerable mirror","description":"A projection video display device, which enlarges and projects an image from an image-displaying means, has a housing and a raisable/lowerable mirror and a power supply, a light source, and a lens uni","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9846354","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.
