Claims (6)

  1. 내부에 확대용 광학계를 장착한 거울통의 기단부측에 확대용 광원계를 통하여 얻어지는 광학상을 전기신호로 변환하는 촬상 소자를 설치시키는 동시에, 거울통의 선단부측에서 투명재료에 따라 대략 반구형으로 형성시키고, 또한 표면 중심부에 관찰용 개구부를 뚫은 도광 캡을 나사맞춤시키고, 그 도광 캡의 반구형 단면부에서 입사하여 그 도광 캡내를 진행하는 조명광을 부여하는 조명 시스템을 구비하여 된 것을 특징으로 하는 확대 촬상 장치의 조명용 도광 장치.
  2. 제1항에 있어서, 복수개의 광 화이버의 선단 방사면을 서로 밀착시킨 형태로 고리 모양을 한 지지고리 위에 심어서 설치시키는 동시에 이 지지고리를 도광 캡의 고리 모양의 개구 선단부에 접촉 또는 작은 간극을 두고서 대향시켜서 된 것을 특징으로 하는 확대 촬상 장치의 조명용 도광 장치.
  3. 제1항 또는 제2항에 있어서, 도광 캡의 주체부의 단면 형상을 바닥측에서 약간 평면적으로 하여 중심부에 관찰 개구부를 뚫는 동시에, 이 바닥에 연결되도록 접속하여 포물선형 단면을 기준으로 한 대략 반구형으로 형성시켜서 된 것을 특징으로 하는 확대 촬상 장치의 조명용 도광 장치.
  4. 제1항 내지 제3항중 어느 한 항에 있어서, 도광 캡의 관찰 개구부 및 고리형 개구 단면부를 제외한 내면 또는 외면 그리고 내외양면에 대하여 저 굴절율인 코팅층 또는 금속 증착층을 형성시켜서 된 것을 특징으로 하는 확대 촬상 장치의 조명용 도광 장치.
  5. 제1항 내지 제4항중 어느 한 항에 있어서, 도광캡의 관찰 개구부의 내측에 접근하여 피 당접부측으로 개구된 가운데 가빈 내부를 가지며, 또한 하부 외주면에 오목한 면 형상의 반사면을 형성한 가운데가 빈 반사 부재와 서로 마주보게 하여서된 것을 특징으로 하는 확대 촬상 장치의 조명용 도광 장치.
  6. 제1항 또는 제3항 내지 제5항중 어느 한 항에 있어서, 복수개의 광 파이버의 선단 방사면을 상호 밀착시켜서 내외 2열로 나눈 형태로 2중의 고리형을 한 내외 2열의 지지 고리위에 각각 심어서 설치시키는 동시에, 한쪽의 외측 지지 고리를 도광 캡의 고리형 개구 단면부에 접촉 또는 작은 간극을 두고서 대향시키는 동시에, 이 외측 지지 고리의 내측에 다른 쪽의 내측 지지 고리를 따라서 배치하여서 된 것을 특징으로 하는 확대 촬상 장치의 조명용 도광 장치,
