Description

보이스코일형 액튜에이터
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 렌즈경통의 요부를 나타낸 중앙종단면도, 제2도는 제1도의 Ⅱ-Ⅱ선에 따른 단면도, 제3도는 일부를 절결하여 나타낸 요부의 사시도.

Claims (1)

  1. 횡단면이 반경방향에 있어서의 전부 또는 일부가 투자성을 가진 재료에 의해 형성된 가이드축과, 이 가이드축에 슬라이드할 수 있게 지지된 이동체와, 이 이동체에 상기 가이드축과 동축이 되도록 지지된 가동코일과, 대략 원통형으로 되고, 가동코일의 이동범위를 에워싸도록 배치된 요크와, 상기 요크와 접촉한 자계발생용의 마그네트를 구비하고, 최소한 요크에는 이들 축방향으로 뻗는 절결이 형성되고, 이동체중 상기 절결을 통하여 돌출한 부분으로 이동부재를 지지한 것을 특징으로 하는 보이스코일형 액튜에이터.
    ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.
