Description

Как известно, транспортирующие ме- j ханизмы кинасъемочных аппаратов дают I скачкообразное движение пленке в рамке, необходимое дл  осуществлени  самого принципа съемки. Прерывистое движение пленки не позвол ет производить разного рода специальные съемки, при которых необходима скорость пор дка нескольких дес тков или сотен кадров в секунду. Скоростна  съемка может быть осуществлена такой системой, при которой пленка двигалась бы в рамке непрерывно без толчков и задержек; здесь вопрос сто л бы только в силе освещени  объекта, допускающей ту или иную быстроту кадров.As it is known, transporting mechanisms of film-making apparatuses give I an intermittent motion to the film in the frame necessary for the implementation of the very principle of shooting. The intermittent motion of the film does not allow for various kinds of special surveys that require speeds of the order of several tens or hundreds of frames per second. High-speed shooting can be carried out by such a system in which the film would move in the frame continuously without jerks and delays; here the question would be worth only in the power of illumination of an object that permits a particular frame rate.

Применение вращающегос  зеркального барабана как будто разрещает вопрос, но из-за сложности, громоздкости механизма и дороговизны оно не .получило должного распространени .The use of a rotating mirror drum seemed to resolve the issue, but because of the complexity, bulkiness of the mechanism and the high cost, it did not receive a proper spread.

Известно дл  этой же цели и применение зеркала, которому сообщаютс  качательные движени ; при этом, при расчетах и конструировании таких комиенсаторов необходимо дать максимальное удлинение времени проекции кадра на экран с сокращением до последней возможности возвратного движени  зеркала.It is known for the same purpose and use of a mirror to which the swinging movements are communicated; in this case, in the calculations and design of such commensers, it is necessary to give the maximum lengthening of the frame projection time on the screen with reduction to the last possibility of the return movement of the mirror.

При съемочном аппарате, где, благодар  затемн ющему сектору обтюратора , доход щего до 240 возвратный путь зеркала происходит гораздо медленнее , механизм компенсатора может быть выполнен иначе, причем наиболее существенным элементом здесь  вл етс  установка обтюратора.With a survey device, where, due to the darkening sector of the shutter, reaching up to 240, the return path of the mirror is much slower, the compensator mechanism can be executed differently, with the installation of the shutter being the most important element.

В предлагаемом приспособлении обтюратор снабжен ободом, на который опираетс  рычаг, сочлененный с зеркалом , причем обтюратор установлен наклонно .In the proposed device, the obturator is provided with a rim on which a lever articulated with a mirror is supported, the obturator being inclined.

На чертеже фиг. 1 показывает схему установки; фиг 2 и фиг. 2-вид обтюратора спереди и сбоку и фиг. 3-схему устройства с другим расположением призмы.In FIG. 1 shows an installation diagram; FIG. 2 and FIG. 2 is a front and side view of the obturator, and FIG. 3-diagram of the device with a different location of the prism.

Как видно из чертежа, пленка 1 движетс  с подающей кассеты I в приемную II через окно рамки 2, с помощью транспортирующего барабана (или барабанов ) 3. Изображение, спроектированное объективом 4, направл етс  на зеркало 5, с которого оно должно попадать на пленку, что и произойдет, если на врем  экспозиции путь световым лучам будет открыт щелью обтюратора 6, наход щегос  перед фильмом. Обтюратор может иметь, как и обычно, посто нную или раздвижнуюAs can be seen from the drawing, the film 1 moves from the feeding cassette I to the receiving II through the window of the frame 2 by means of the transporting drum (or drums) 3. The image, designed by the lens 4, is directed to the mirror 5, from which it should fall onto the film, what will happen if during the exposure time the path to the light rays is opened by the slit of the obturator 6, which is in front of the film. The obturator can be, as usual, constant or sliding
