Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명 음성 코일형 작동기를 카메라의 렌즈계에서 쥬밍(zooming)용의 가동 렌즈를 이동시키기 위해 작동기에 적용하는 제1의 실시예의 렌즈 경통(鏡筒)의 요부를 도시하는 중앙 종단면도.
제2도는 제1도의 II-II선을 취한 단면도.
제3도는 요크의 일부를 절취하여 도시하는 요부의 확대 사시도.
Claims (2)
- 횡단면의 반경방향에서 모두 또는 일부가 유전성을 갖는 재료로 형성된 가이드 축과, 이 안내축에 미끄러져 이동 가능하게 지지된 이동체와, 이 이동체에 상기 안내축과 동축이 되도록 지지된 가동 코일과, 거의 원통형상으로 구성되고 가동코일의 이동 범위를 감싸도록 설치된 요크와, 가동 코일의 축과 직교하는 방향으로 극성이 다르도록 자화되어 가동 코일의 이동 범위의 양단과 각각 별도로 마주하고 안내축 및 요크와 접촉하도록 설치된 2개의 자석을 구비하고, 적어도 요크에는 그축방향으로 연장되는 절취부가 형성되어 이동체의 상기 절취부를 통해 돌출한 부분에서 소정의 이동 부재를 지지하고 있는 것을 특징으로 하는 음성 코일형 작동기.
- 제1항에 있어서, 자석이 링형상으로 구성됨과 동시에 반경방향으로 상이한 극성으로 자화되어 있고 그 내주면이 안내축과 접촉하여 외주면이 요크와 접촉하고 있는 것을 특징으로 하는 음성 코일형 작동기.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
