본 발명은 산업용 첨단소재의 제작상태를 검시함에 있어서, 소재를 일정비율 확대하여 주는 영상확대기에 동축조명과 낙사조명을 동시에 공급하여서 중앙변위부의 밝기를 조절하여 심도를 길게 함으로써, 검시하고자 하는 대상물의 검시범위를 확대하기 위한 것으로, 특히 검시면이 원형이나 구형으로된 곡면일 때 곡면을 따라 넓게 관찰이 가능하도록 하여 검시가 용이하도록 한 것이다.In the present invention, when inspecting the manufacturing state of the industrial high-tech materials, by supplying coaxial and fall light simultaneously to the image magnifier that enlarges the material by a certain ratio, by adjusting the brightness of the central displacement portion to increase the depth of the object to be examined In order to expand the scope of the examination, in particular, when the examination surface is a round or spherical surface is to facilitate the inspection by allowing a wide observation along the curved surface.

일반적으로 광학을 이용한 영상확대기는 카메라, 복사기, 인쇄기, 현미경등에 많이 사용되는바, 현재에는 많은 발전으로 산업용 부품등 작고 정밀한 제품의 제조 및 가공상태를 측정함에 있어서 영상확대기로 검시하는 제품이 모니터에 보다 확대되어 나타나 육안으로 제품의 상태를 쉽게 판별하도록 하고 있다.In general, optical image magnifiers are widely used in cameras, photocopiers, printers, microscopes, etc.As a result of many developments, products that are inspected with image magnifiers are used to monitor the manufacturing and processing conditions of small and precise products such as industrial parts. It is enlarged so that the state of the product can be easily identified with the naked eye.

그러나 지금까지의 영상확대기는 제품을 관찰함에 있어서 첨부도면 제 1 도에 예시한 바와 같이 동축조명에만 의존함으로써, 영상확대기의 선단 렌즈를 통하여 투사되는 빛만이 관찰하고자 하는 제품의 일부면에 전달되어 그 관찰범위가 극히 작을뿐만 아니라, 특히 관찰대상면이 원형 등 곡면일때는 일부분만 관찰되는 등 많은 문제점이 있었다.However, until now, the image magnifier relies only on coaxial illumination, as illustrated in FIG. 1, in observing the product, so that only light projected through the tip lens of the image magnifier is transmitted to a part of the product to be observed. Not only the observation range was extremely small, but there were many problems, such as only a part of the observation surface, especially when the object surface was a round surface.

본 발명은 상기한 지금까지의 제결함을 감안하여 배율렌즈군이 구비된 경통선단에 원추형의 반사경을 설치하고, 상기 반사판에 경통내부에 렌즈군을 통하여 인가되는 동축조명과는 별도로 낙사조명을 공급하여서 관찰하고자 하는 대상물의 보다 넓은 범위에 조명을 전달함으로써 보다 넓고 큰 범위가 뚜렷하게 관찰되도록 함에 그 첫번째 목적이 있으며, 상기와 같이 관찰범위가 넓게 함으로써 관찰대상면이 곡면일지라도 일정범위가 뚜렷하게 나타나 쉽게 검시하도록 하여, 산업체에서 검시에 소요되는 시간을 단축하는 등 일의 능률향상에 일층 기여하도록 함에 두 번째 목적이 있다.The present invention provides a cone-shaped reflector at the tip of the barrel provided with the magnification lens group in view of the above-mentioned defects, and supplies the fall light separately from the coaxial illumination applied through the lens group to the reflector. The first purpose is to ensure that the wider and larger range is clearly observed by transmitting illumination to a wider range of the object to be observed, and as the above observation range is wider, even if the observed surface is curved, a certain range is clearly seen and easily examined. The second purpose is to contribute to the improvement of the efficiency of work, such as to reduce the time required for the necropsy in the industry.
