촬영 렌즈(41)가 편입된 렌즈 유닛(40)과, 촬상 소자(52)가 부착된 센서 기판(51)을 접합하는 카메라 모듈 제조 장치(100)로서, 콜리메이터 렌즈(31, 33)와 측정 차트(32, 34)를 포함하고, 측정 차트(32, 34)의 상을 촬영 렌즈(41)를 통과시켜 촬상 소자(52)에 결상시키는 광학 유닛(10)을 구비하고, 광학 유닛(10)에 의해 촬상 소자(52)에 결상시킨 측정 차트(32, 34)의 상을 촬상 소자(52)가 변환한 화상 신호에 기초하여 렌즈 유닛(40)과 센서 기판(51)과의 상대 위치를 조정하고, 측정 차트(32, 34)가 콜리메이터 렌즈(31, 33)의 광축(31a, 33a)에 수직인 면에 대하여 경사져 배치되어 있다. There is disclosed a camera module manufacturing apparatus for joining together a lens unit that incorporates a taking lens and a sensor board to which an image sensor is attached. The camera module manufacturing apparatus includes an optical unit including a collimator lens and a measurement chart for forming an image of the measurement chart on the image sensor through the taking lens. The relative position of the lens unit and the sensor board is adjusted based on an image signal obtained by converting, using the image sensor, an image of the measurement chart that is formed on the image sensor by the optical unit. The measurement chart is disposed to be tilted with respect to a plane that is perpendicular to an optical axis of the collimator lens.
