Title (EN) BLADE DRIVE DEVICE
(FR) DISPOSITIF D'ENTRAÎNEMENT DE LAME
(JA) 羽根駆動装置
Abstract:
(EN) The present invention enables the adjustment of a lens frame (lens barrel) to be performed singly and also makes thin shaping along the direction of an optical axis possible. A blade drive device 1 is provided with a drive member 2 that moves on a plane, a frame 3 in which the drive member is accommodated, a thin-shaped blade support 4 protruding from a portion of the thickness of the frame 3 to the outside along the movement direction of the drive member 2 and having an opening 4A around an optical axis running along the thickness direction of the frame 3, and a blade member 5 supported by the blade support 4 and moved by the drive member 3 to enter the opening 4A, the outer circumferential edge of the frame 3 having a recess 3A at the protruding position of the blade support 4.
(FR) Grâce à la présente invention, le réglage d'un cadre de lentille (barillet) peut être réalisé individuellement et une mise en forme mince le long de la direction d'un axe optique est également possible. Un dispositif d'entraînement de lame (1) est pourvu d'un élément d'entraînement (2) qui se déplace sur un plan, d'un cadre (3) dans lequel l'élément d'entraînement est logé, d'un support de lame de forme mince (4) faisant saillie à partir d'une partie de l'épaisseur du cadre (3) vers l'extérieur le long de la direction de déplacement de l'élément d'entraînement (2) et comportant une ouverture (4A) autour d'un axe optique s'étendant le long du sens de l'épaisseur du cadre (3), et d'un élément de lame (5) soutenu par le support de lame (4) et déplacé par l'élément d'entraînement (3) en vue de pénétrer dans l'ouverture (4A), le bord périphérique externe du cadre (3) comportant un évidement (3A) au niveau de la position en saillie du support de lame (4).
(JA) レンズ枠(レンズバレル)の調整を単独で行うことが可能であり、しかも光軸方向に沿った薄型化を可能にする。羽根駆動装置1は、平面上を移動する駆動部材2と、駆動部材2を収容した枠体3と、枠体3の厚みの一部から駆動部材2の移動方向に沿って外部に突出し、枠体3の厚さ方向に沿った光軸周りの開口4Aを有する薄厚状の羽根支持体4と、羽根支持体4に支持され、駆動部材3によって移動して開口4Aに進入する羽根部材5とを備え、枠体3の外周縁は、羽根支持体4の突出位置に凹部3Aを有する。
