Title (EN) LENS BARREL
(FR) BARILLET DE LENTILLE
(JA) レンズ鏡筒
Abstract:
(EN) A lens barrel (100) is provided with a first lens frame (210) that holds a first lens (211), and a second lens frame (220) that holds a second lens (221), said second lens frame (220) holding the first lens frame (210) such that the first lens frame can freely move in the direction of an optical axis (L). The lens barrel is also provided with a pair of linear units (310) that drive the first lens frame (210) movement in the direction of the optical axis (L). When viewed from the direction of the optical axis (L), the pair of linear units (310) are disposed along the outer periphery of the first lens frame (210), said linear units being at positions not facing each other by having the optical axis (L) therebetween.
(FR) Selon la présente invention, un barillet de lentille (100) est pourvu d'un premier cadre de lentille (210), qui retient une première lentille (211), et d'un second cadre de lentille (220), qui retient une seconde lentille (221), ledit second cadre de lentille (220) retenant le premier cadre de lentille (210) de telle sorte que le premier cadre de lentille peut se déplacer librement dans la direction d'un axe optique (L). Le barillet de lentille est également pourvu d'une paire d'unités linéaires (310) qui entraînent le mouvement du premier cadre de lentille (210) dans la direction de l'axe optique (L). Vu depuis la direction de l'axe optique (L), les deux unités linéaires (310) sont disposées le long de la périphérie extérieure du premier cadre de lentille (210), lesdites unités linéaires étant à des positions qui ne se font pas face l'une à l'autre, l'axe optique (L) se trouvant entre ces dernières.
(JA) レンズ鏡筒(100)は、第一レンズ(211)を保持する第一レンズ枠(210)と、第二レンズ(221)を保持する第二レンズ枠(220)であって、第一レンズ枠(210)を、光軸(L)の方向に移動自在に保持する第二レンズ枠(220)とを備え、第一レンズ枠(210)の、光軸(L)の方向の移動を駆動する一対のリニアユニット(310)とを備える。一対のリニアユニット(310)は、光軸(L)の方向から見た場合に、第一レンズ枠(210)の外周に沿って、かつ、光軸(L)を挟んで互いに対向しない位置に配置されている。
