Abstract

사용자가 조작을 통해 렌즈를 광축방향으로 원하는 위치로 이동시켜 초점을 조절할 수 있도록 하는 초점조절용 렌즈구동기구가 개시된다. 이 렌즈구동기구는 내부에 구속홈이 피구동렌즈의 광축방향으로 길게 마련된 브라켓과, 상기 브라켓에 의해 회전가능하게 지지되며 몸체의 적어도 일면에 회전중심으로부터 편심된 환형 홈이 마련된 초점조절용 다이얼을 갖는다. 또한, 상기 환형 홈 안에 삽입된 가이드돌기와, 상기 브라켓의 상기 구속홈에 삽입된 돌출부와, 상기 브라켓 외부로 길게 연장된 렌즈구동축을 구비하는 렌즈구동부재도 갖는다. 이들을 수납한 채 렌즈조립체 하우징에 고정되는 렌즈구동부재 하우징을 더 가질 수도 있다. 다이얼에 가해지는 외부 충격을 완충할 수 있는 충격완충수단을 더 가질 수도 있다. 다이얼이 소정방향으로 회전할 때 편심 환형 홈이 가이드돌기를 가이드하면서 가하는 힘과 구속홈이 돌출부를 광축방향으로의 움직임은 허용하되 광축방향에 직교하는 렌즈구동축 방향으로의 움직임은 불허하는 구속의 조합에 의해, 렌즈구동축이 광축방향으로 소정구간 진퇴한다. 이에 의해, 렌즈구동축에 삽입 결합된 피구동렌즈를 광축방향으로 소정구간 진퇴시킬 수 있다.
