Title (EN) CAMERA IRIS DRIVING APPARATUS
(FR) APPAREIL D'ENTRAÎNEMENT D'IRIS DE CAMÉRA
(KO) 카메라의 아이리스 구동장치
Abstract:
(EN) A camera iris driving apparatus according to the present invention comprises: a first magnet and a second magnet arranged at different locations; a blade having an opening through which light is introduced, the blade adjusting an amount of light introduced into a lens by physical movement; a driving unit for driving physical movement of the blade; and a blade yoke disposed on the blade to generate a force of attracting the first or second magnet according to a position of the blade, the blade yoke being made of a magnetic material.
(FR) Un appareil d'entraînement d'iris de caméra selon la présente invention comprend : un premier aimant et un second aimant disposés à différents emplacements ; une lamelle ayant une ouverture à travers laquelle de la lumière est introduite, la lamelle ajustant une quantité de lumière introduite dans une lentille au moyen d'un mouvement physique ; une unité d'entraînement permettant d'entraîner un mouvement physique de la lamelle ; et un étrier de lamelle disposé sur la lamelle en vue de générer une force d'attraction du premier ou du second aimant en fonction d'une position de la lamelle, l'étrier de lamelle étant constitué d'un matériau magnétique.
(KO) 본 발명에 의한 카메라의 아이리스 구동장치는 서로 다른 위치에 구비되는 제1 및 제2마그네트; 빛이 유입되는 개구부를 가지며 물리적 이동에 의하여 렌즈로 유입되는 빛의 양을 조절하는 블레이드; 상기 블레이드의 물리적 이동을 구동하는 구동부; 및 상기 블레이드에 구비되며 상기 블레이드의 위치에 따라 상기 제1 또는 제2마그네트와 인력을 발생시키는 자성 재질의 블레이드 요크를 포함하는 것을 특징으로 한다.
