Title (EN) LENS MOVING MECHANISM
(FR) MÉCANISME DE DÉPLACEMENT DE LENTILLE
(JA) レンズ移動機構
Abstract:
(EN) This lens moving mechanism is equipped with a lens mount to which a lens for projecting light is mounted, a guide unit that supports the lens mount while guiding the lens mount in three orthogonal axis directions including the optical axis of the light, and a frame unit to which the guide unit is fixed. The guide unit is equipped with a plurality of linear-motion guide devices each equipped with a track rail that is fixed to the frame unit and a slider block that moves along the track rail. A plurality of the track rails are disposed coaxially on the frame unit.
(FR) Selon la présente invention, ce mécanisme de déplacement de lentille est équipé d'une monture de lentille sur laquelle est montée une lentille de projection de lumière, une unité de guidage qui supporte la monture de lentille tout en guidant la monture de lentille dans trois directions d'axe orthogonal comprenant l'axe optique de la lumière, et une unité de cadre à laquelle l'unité de guidage est fixée. L'unité de guidage est équipée d'une pluralité de dispositifs de guidage à mouvement linéaire équipés chacun d'un rail de voie qui est fixé à l'unité de cadre et d'un bloc coulissant qui se déplace le long du rail de voie. Une pluralité de rails de voie sont disposés coaxialement sur l'unité de cadre.
(JA) レンズ移動機構は、光を投射するレンズが取り付けられるレンズマウントと、レンズマウントを支持すると共に、レンズマウントを、光の光軸を含む3軸直交方向に案内する案内部と、案内部が固定されるフレーム部と、を備える。案内部は、フレーム部に固定される軌道レールと、軌道レールに沿って移動するスライダブロックと、を備える直動案内装置を複数備える。フレーム部には、軌道レールが、同軸上で複数配置されている。
