Abstract
The shutter in front of the image aperture is constructed from two pairs of flaps which fold and unfold and are actuated by levers so that flap edges move as leading and trailing edges of a slit across the aperture. The flaps fold temporarily into the space occupied, for example, by a fold-up mirror prior to exposure if the camera is of the single reflex type.
