Claims (3)
- 렌즈 지지체와, 렌즈 지지체의 외주측(外周側)에 고정한 코일과, 단면이 "ㄷ"자 형상으로 내주측(內周側)에 개구를 갖는 요크(yoke)와, 상기 요크가 장착되는 베이스와, 상기 요크의 내부에 설치한 자석을 구비하고, 상기 코일에 통전해서 상기 렌즈 지지체를 이동시키는 렌즈 구동 장치로서,상기 렌즈 지지체는 외주에 플랜지부를 구비하고,상기 플랜지부에는 코일 부착부와 요크 맞닿음부가 설치되어 있고,상기 코일 부착부는 요크의 내부에 위치하여, 코일을 접착 고정하고 있고,상기 플랜지부는 상기 베이스와 상기 요크 맞닿음부 사이의 공간을 전후로 이동하여 상기 렌즈 지지체의 이동을 규제하고 있으며,상기 플랜지부에는 렌즈의 이동 방향으로의 길이가 상기 요크 맞닿음부보다도 짧은 접착제 도피부가 형성되어 있는 것을 특징으로 하는 렌즈 구동 장치.
- 제1항에 있어서, 상기 접착제 도피부의 외주 측면이 상기 요크 맞닿음부의 외주 측면보다도 상기 코일 부착부 측으로 돌출되어 있는 것을 특징으로 하는 렌즈 구동 장치.
- 제1항 또는 제2항에 있어서, 상기 코일 부착부에는 다수의 요철(凹凸)이 형성되어 있는 것을 특징으로 하는 렌즈 구동 장치.
