Description

прерывисто перемешаем паспорт 2 на один шаг. В этот момент темные участки паспорта 2, расположенные между двум  группами экспозиционных отверстий, проход т в пучке печатного света, частично перекрыва  его. В результате экспозици  в окне 5 изменитс . Экспозици  имеет переменное значение до тех пор, пока темные участки паспорта 2 не выйдут из светового потока. Вследствие этого при печати по витс  недодержка , т.е. образуетс  светлый кадр, который при демонстрации фильма резко действует на зрение зрителей. Дл  этого позитив 8 в печатном окне 5 засвечиваетс  светом от дополнительного источника света 6, а включение его производитс  кулачком 4, св занным с зубчатым барабаном 3. Кулачок 4 сфазирован с зубчатым барабаном так, что засветка пизитива 8 происходит в момент прохождени  темных участков паспорта 2. Устройство полностью исключает пропечатывание светлых полос при сменеintermittently shuffle the passport 2 one step. At this moment, the dark areas of the passport 2, located between the two groups of exposure holes, pass through the beam of printed light, partially blocking it. As a result, the exposure in window 5 changes. The exposure is variable until the dark areas of the passport 2 come out of the light flux. As a result, when printing on Wits underexposure, i.e. a bright frame is formed, which dramatically affects the eyes of the audience when the film is shown. For this, the positive 8 in the printed window 5 is illuminated by the light from the additional light source 6, and it is turned on by cam 4 connected to the toothed drum 3. Cam 4 is phased with the toothed drum so that illumination of the pivot 8 occurs when the dark passport 2 The device completely eliminates the printing of light bands when changing
