ABSTRACT:
A cassette containing a stack of film units having overlapping positive and negative sheets has a housing with first and second side walls having first and second openings, and a light-admitting aperture between the two side walls. The film units are stored in a first compartment of the housing adjacent to the aperture in such a way that the foremost unit is in register with the opening in one of the side walls. A discrete withdrawing strip for each film unit has an inner portion adhering to the rear side of the respective unit and an outer portion extending outwardly through the opening in the other side wall. The withdrawing strips form a bundle which extends through a channel connecting the first compartment with a second compartment behind the stacked film units. When a withdrawing strip is extracted from the housing, its inner portion is peeled off the rear side of the corresponding freshly exposed film unit while the latter leaves the housing via the opening in the one side wall and enters a developing unit. A cover sheet is located in front of the foremost film unit or in front of each film unit to allow for the making of a test exposure in a photographic copying machine prior to extraction of the cover sheet with the help of an additional withdrawing strip which extends outwardly through the opening in the other side wall of the housing.
