Title (EN) LENS BARREL AND IMAGING DEVICE
(FR) BARILLET DE LENTILLE ET DISPOSITIF D'IMAGERIE
(JA) レンズ鏡筒及び撮像装置
Abstract:
(EN) Provided is a lightweight lens barrel comprising two focus lenses. A lens barrel 2 is provided with: a first lens L5; a first lens holding frame 50 that holds the first lens L5; a first driving unit STM5 that moves the first lens holding frame 50 in a light axis direction; a second lens L6 disposed at the object side of the first lens L5 in the light axis direction; a second lens holding frame 60 that holds the second lens L6; and a second driving unit STM6 that moves the second lens holding frame 60 in the light axis direction. The first lens holding frame 50 and/or the second lens holding frame 60 has barrel sections 52, 62 extending to the object side in the light axis direction.
(FR) L'invention concerne un barillet de lentille léger comprenant deux lentilles focales. Un barillet 2 de lentille comprend : une première lentille L5 ; un premier cadre 50 de support de lentille qui supporte la première lentille L5 ; une première unité d'entraînement STM5 qui déplace le premier cadre 50 de support de lentille dans une direction d'axe lumineux ; une seconde lentille L6 disposée du côté objet de la première lentille L5 dans la direction de l'axe lumineux ; un second cadre 60 de support de lentille qui supporte la seconde lentille L6 ; et une seconde unité d'entraînement STM6 qui déplace le second cadre 60 de support de lentille dans la direction de l'axe lumineux. Le premier cadre 50 de support de lentille et/ou le second cadre 60 de support de lentille ont des sections 52, 62 de barillet s'étendant vers le côté objet dans la direction de l'axe lumineux.
(JA) 2つのフォーカスレンズを備える軽量なレンズ鏡筒を提供する。 レンズ鏡筒2は、第1レンズL5と、記第1レンズL5を保持する第1レンズ保持枠50と、前記第1レンズ保持枠50を光軸方向に移動させる第1駆動部STM5と、光軸方向において前記第1レンズL5の物体側に配置される第2レンズL6と、前記第2レンズL6を保持する第2レンズ保持枠60と、前記第2レンズ保持枠60を光軸方向に移動させる第2駆動部STM6と、を備え、前記第1レンズ保持枠50及び前記第2レンズ保持枠60の少なくとも一方は、光軸方向において物体側に延びる筒部52,62を有する。
