Description
제1도는 본 고안의 투시함을 개방한 상태의 사시도.1 is a perspective view of the open state of see-through box of the present invention.
제2도는 본 고안의 측 단면도.2 is a side cross-sectional view of the present invention.
제3도는 본 고안의 설명도이다.3 is an explanatory diagram of the present invention.
본 고안은 사진관 등에서 사용하는 통상의 대형 사진기에 본원의 투시함을 구성시킴으로써, 영상창에 나타난 피사체의 영상을 외부의 광선을 별도로 차단함이 없이 육안으로 간편하게 투시하여 피사체의 촛점을 용이하게 조절될 수 있게한 사진기 영상창의 투시함 장치에 관한 것이다.The present invention is configured by the perspective view of the present application to a conventional large-sized camera used in photo studios, such that the image of the subject shown in the image window can be easily viewed by the naked eye without blocking the external rays separately to easily adjust the focus of the subject. To a see-through device of a camera video window.
종래의 대형 사진기를 사용하여 사진을 촬영할 시에는 검은색의 암막(暗幕)을 사진기에 덮어 씌워서 외부 광선을 완전히 차단하고, 그 안에 머리를 넣어서 영상창에 나타나는 피사체의 영상을 육안으로 보면서 렌즈를 전후 이동시켜 그 촛점을 맞추었던 것이어서, 그 촬영 작업이 매우 번거러웠던 결점이 있었다.When taking a picture using a conventional large-sized camera, cover the camera with a black black film to completely block external light rays, and insert the head into it to visually see the image of the subject appearing in the video window. There was a flaw that the filming was very cumbersome because it was moved and focused.
본 고안은 이와 같은 종래의 결점을 제거하기 위하여 고안한 것으로써 본 고안의 요지를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The present invention is devised to remove such a conventional defect, and the present invention will be described in detail with reference to the accompanying drawings.
통상의 사진기 본체(1)의 영상창(2) 후면 일측에 투시함(3)을 설착하여 경첩(4)(4')에 의하여 개폐되게하되, 투시함(3)의 경사진 내저면에 공지의 반사경(5)을 장착하고, 그 상부에 공지의 오목렌즈계의 대안렌즈(6)를 착설되게한 구조이다.The see-through box (3) is installed on one side of the rear side of the video window (2) of the conventional camera body (1) to be opened and closed by the hinge (4) (4 '), but notified to the inclined inner bottom of the see-through box (3). The reflector 5 is mounted, and on the upper portion thereof, a known alternative lens 6 of a concave lens system is installed.
미설명부호 7은 대물렌드, 8은 필름, A는 피사체, B는 영상창의 상(像), C는 대안렌즈(6)를 보는 육안이다.Reference numeral 7 denotes an objective lens, 8 a film, A a subject, B an image of an image window, and C is a naked eye looking at the alternative lens 6.
이와 같이 구성되는 본 고안을 실시할 경우 그 작용 효과를 설명하면, 제3도에 도시된 바와 같이, 피사체(A)가 빛에 의해 투영되면 대물렌즈(7)를 통하여, 영상창(2)에 도립실상(B)이 나타난다. 따라서 이 도립실상(B)을 육안(C)로 직접 보면서 피사체(A)의 촛점을 맞추는 것인데, 본 고안은 공지의 대안렌즈(6)를 통하여 투시함(3)의 내저면에 경사지게 고정한 공지의 반사경(5)을 보면 영상창(2)의 도립실상(B)이 반사되어 공지의 대안렌즈(6)를 통하여 육안(C)으로 바로 볼 수 있게한 것이다.In the case of implementing the present invention configured as described above, the operation and effect thereof will be described. As shown in FIG. 3, when the subject A is projected by light, the object window 7 is connected to the image window 2. Inverted phase image (B) appears. Therefore, while focusing on the subject A while looking directly at the inverted chamber image B with the naked eye C, the present invention is known to be inclinedly fixed to the inner bottom of the see-through box 3 through a known alternative lens 6. Looking at the reflector 5, the inverted chamber image B of the image window 2 is reflected so that it can be directly seen by the naked eye C through the known alternative lens 6.
따라서 대형 사진기에 본 고안의 투시함 장치를 실시할 경우는 사진기에 전기한 바와 같은 암막을 씌워서 외부 광선을 차단하지 아니하여도 공지의 대안렌즈(6)를 통하여 피사체(A)의 영상의 촛점을 간편하게 맞출 수 있게 되므로, 다음은 통상의 방법과 같이 필름(8)을 영상창(2)안에 삽입시켜 공지의 셔터로 노출시켜, 촬영 작업을 쉽게 할 수 있는 효과가 있는 것인데, 본 고안의 투시함(3)의 내부는 물론 외부 광선을 완전 차단하게 되어 있어서, 영상창의 상을 세밀하게 조절할 수 있게한 것이다.Therefore, when implementing the see-through device of the present invention on a large-sized camera, the focus of the image of the subject A can be focused through a known alternative lens 6 without covering external light by covering the black film as described in the camera. Since it can be easily fitted, the following is to insert the film 8 into the video window 2 and expose it with a known shutter as in the usual method, so that the photographing operation can be easily performed. The inside of (3) is, of course, completely blocked the external light, so that the image of the video window can be finely adjusted.
