Title (EN) OPTICAL APPARATUS
(FR) APPAREIL OPTIQUE
(JA) 光学機器
Abstract:
(EN) An optical apparatus that includes an object-side main body, to which an eyepiece-side supporting member that supports an eyepiece-system optical member can be attached and detached, and an object-system optical member, which is supported by the object-side main body, is provided with: housing (102) that houses at least part of the eyepiece-side supporting member; operation members (130, 170, 180) that are operated rotatably with respect to the housing (102); a driven member (140) that is driven and displaced by the rotation of the operation members (130, 170, 180); and a gripping member (160), at least part of which is arranged on the inside of the housing (102), that grips the eyepiece-side supporting member when the driven member (140) is displaced. When the gripping force exerted on the eyepiece-side supporting member by the gripping member (160) reaches a predetermined value, the operation members (130, 170, 180) are idle with respect to the driven member (140).
(FR) La présente invention concerne un appareil optique qui contient : un corps principal côté objet par rapport auquel un élément de support côté oculaire, qui supporte un élément optique d'un système d'oculaire, peut être attaché ou détaché ; et un élément optique d'un système d'objet qui est supporté par le corps principal côté objet. L'appareil optique comprend : un logement (102) qui loge au moins une partie de l'élément de support côté oculaire ; des éléments d'actionnement (130, 170, 180) qui sont actionnés de manière rotative par rapport au logement (102) ; un élément entraîné (140) qui est entraîné et déplacé par la rotation des éléments d'actionnement (130, 170, 180) ; et un élément de saisie (160) dont au moins une partie est située à l'intérieur du logement (102) et qui saisit l'élément de support côté oculaire quand l'élément entraîné (140) est déplacé. Quand la force de saisie exercée sur l'élément de support côté oculaire par l'élément de saisie (160) atteint une valeur prédéterminée, les éléments d'actionnement (130, 170, 180) tournent à vide par rapport à l'élément entraîné (140).
(JA)  接眼系光学部材を支持する接眼側支持部材が着脱可能な対物側本体部と、対物側本体部に支持された対物系光学部材とを備える光学機器であって、接眼側支持部材の少なくとも一部を収容する収容部(102)と、前記収容部(102)に対して回転操作される操作部材(130、170、180)と、回転する前記操作部材(130、170、180)に駆動されて変位する従動部材(140)と、前記収容部(102)の内側に少なくとも一部が配され、前記従動部材(140)が変位した場合に接眼側支持部材を把持する把持部材(160)とを備え、前記操作部材(130、170、180)は、前記把持部材(160)から接眼側支持部材に掛かる把持力が予め定められた値に達した場合に前記従動部材(140)に対して空回りする。
