The open-close mechanism includes: drive blocks 308 fixed to a pair of aperture plates 301; a linear motion guide 306 allowing the drive blocks to move along an axis; a feed screw 302 parallel to the axis, on which a pair of helical threads proceeding in opposite directions formed; nut members 305 each of which is provided in a manner to be engaged with one of the pair of helical threads and is prevented from rotating due to a rotation of the feed screw; an urging member 309 for pressing the drive blocks onto the nut members, respectively; and a distance adjustment member 310 placed between one drive block and the corresponding nut member, for adjusting the distance between them. With this mechanism, a discrepancy between the open-close center of the aperture plates from the rotation center can be cancelled even after the mechanism is assembled."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Aperture-plate drive mechanism","description":"Provided is an aperture-plate drive mechanism including an aperture-plate open-close mechanism and a rotation mechanism for rotating the open-close mechanism.
