Electromagnetically driven slotted shutter for exposing a film in a camera with steady burning light and flashlight runs a continuous shutter curtain with an aperture around two guide devices on bearings and parallel to each other.

摘要

When a shutter assembly is inactive, a beam path between lens (1) and film (4) is completely blocked off by a shutter curtain. The film stays inside the assembly. An aperture (6) has larger dimensions than the film and is on the side opposite the lens in its output position. As the rollers start to rotate, the shutter curtain moves in such a way that the aperture creeps around one of the rollers towards the opposite side of the assembly facing the lens.
