Description

Предметом изобретени   вл етс  кассета,  вл юща с  приставкой дл  репродуцировани  к стандартному фотоувеличителю и предназначенна  дл  съемки на познтивгюй кинопленке чертежей, текста и др. объектов, которые слишком малы, чтобы заполнить кадр при обычной съемке фотоаппаратом.The subject matter of the invention is a cassette, which is an attachment for reproducing a standard photo enlarger and intended for shooting on cognitive film of drawings, text and other objects that are too small to fill a frame with a normal shooting with a camera.

Существующие устройства, примен емые дл  этой же цели (репродукционный объектив, репродукционный увеличитель и т. п.) имеют тот недостаток, что не позвол ют точно определ ть границы снимаемой площади и требуют при фокусировке точного измерени  рассто ни  от объекта съемки до камеры.Existing devices used for the same purpose (reproduction lens, reproduction enlarger, etc.) have the disadvantage that they do not allow accurate determination of the boundaries of the area to be captured and require accurate measurement of the distance from the subject to the camera when focusing.

Оиисываема  кассета дл  репродуцировани  устран ет эти недостатки тем, что дл  определени  границ снимаемо площади и наводки на резкость по углам ее кадрового окна просверлены отверсти , через которые при включении лампы увеличител  проицируютс  световые на объект съемки.The reproduced cassette for reproduction eliminates these drawbacks by the fact that for defining the boundaries of the area to be removed and focusing on the sharpness at the corners of its frame window, holes are drilled through which light is projected onto the subject when the lamp is turned on.

На фиг. 1 изображен продольный разрез кассеты ;на фиг. 2-кассета , вид сверху.FIG. 1 shows a longitudinal section of the cassette; FIG. 2-cassette, top view.

Кассета дл  репродуцировани  состоит из корпуса 1, снабженного двум  гнездами 2 и 3, предназначенными соответственно дл  незасн той и засн той пленки. Гнезда дл  пленкн закрыты крышками 4 и 5. Дл  перемотки пленки служит рз/чка 6, при этом отсчет кадров производитс  с помощью пружинки 1, щелкающей по перфораци м пленки. Дл  наводки на резкость и определеьи  границ сн л;аемой площади служат отверсти  (S, просверленные по углам кадрового окна 9. Положение пленки в кассете ноказаио ка чертеже пунктпром.The reproduction cassette consists of a housing 1, equipped with two sockets 2 and 3, designed respectively for an empty and covered film. The film slots are covered with lids 4 and 5. RZ / nk 6 serves to rewind the film, while the frames are counted by means of a spring 1 that clicks through the perforations of the film. For focusing and defining the boundaries of the film; holes are used as the area (S, drilled in the corners of the personnel window 9. The position of the film in the drawing cassette is shown in point drawing.

Дл  репродуцировани , кроме описанной кассеты, необходимо иметь увеличитель с обычным объективом и одну кассету от фотоаппарата.For reproduction, besides the cassette described, it is necessary to have an enlarger with a conventional lens and one cassette from the camera.

Кассета дл репродуцировани : с помощью фотоувеличител , отличающа с  тем, что, с целью, определени  границ снимаемого пространства и наводки на резкость, пОугл м кадрового окна просверлены отверсти , .4ерез которые при вкл1ачении лампы увеличител  проиЦируютс  световые точки.Reproduction cassette: using a photographic enlarger, characterized in that, in order to determine the boundaries of the shooting space and focus on sharpness, holes have been drilled in the frame window, which, when the lamp is enlarged, light points are reproduced.
