The first, the second, and the third actuators are connected with the optical member at first, second, and third vertices of a triangle imaginarily drawn on a plane parallel to the parallel plate face of the optical member. The first, the second, and the third actuators drive the optical member forward and backward in a normal direction of the parallel plate face at the first, the second, and the third vertices serving as points of load. The optical member has a center of gravity within the triangle when seen from the normal direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical path changing device and projection image display apparatus","description":"The optical path changing device of the present disclosure includes an optical member having a parallel plate face for changing an optical path, and first, second, and third actuators.
