Description

카메라의 자동 초점조절장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 일반적인 카메라의 자동촛점 조절장치 개략적으로 도시한 일부절개 사시도, 제2도는 본 발명에 따른 자동촛점 조절장치의 발광렌즈를 발췌하여 도시한 사시도, 제3도는 자동촛점 조절장치의 발광부로 부터 방출된 적외선 빔이 피사체에 반사되어 수광부에 감지되는 상태를 개념적으로 도시한 사시도.

Claims (3)

  1. 복수개의 포커스 렌즈가 설치된 경통을 가지고 본체와, 상기 경통의 상부에 발광소자의 발광렌즈가 동일한 광축상에 설치되어 피사체에 적외선빔을 발사하는 발광부와, 상기 본체의 일측에 설치되어 상기 발광부로 부터 발사되어 반사되는 적외선빔을 감지하는 수광부를 구비하여된 카메라의 자동촛점 조절장치에 있어서, 상기 발광부의 발광렌즈(10)가 상기 발광소자(8a)로 부터 발광된 적외선을 복수의 방향으로 분산시킬수 있도록 된것을 특징으로 하는 카메라의 자동촛점 조절장치.
  2. 제1항에 있어서, 상기 발광소자로 부터 발광된 적외선빔을 복수의 방향으로 분산시킬수 있도록 된 발광렌즈(10)가 상기 피사체(20)와 대향되는 면을 광축에 대해 수직인 복수의 제1실린더면(11)을 가지며 상기 발광소자(8a)와 대향되는 면은 상기 제1실린더면(11)에 대해 수직으로 제2실린더면(12)을 갖는 것을 특징으로 하는 카메라의 자동촛점 조절장치.
  3. 제1항에 있어서, 상기 본체에 설치되는 수광부(6)의 위치가 상기 발광렌즈(10)의 두적외선 방향을 이루는 면에 대해 수직방향에 위치되는 것을 특징으로 하는 카메라의 자동촛점 조절장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
