Abstract
Provided is an aperture-plate drive mechanism including an aperture-plate open-close mechanism and a rotation mechanism for rotating the open-close mechanism. The open-close mechanism includes: drive blocksfixed to a pair of aperture plates; a linear motion guideallowing the drive blocks to move along an axis; a feed screwparallel to the axis, on which a pair of helical threads proceeding in opposite directions formed; nut memberseach 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 memberfor pressing the drive blocks onto the nut members, respectively; and a distance adjustment memberplaced 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.
