Abstract
The inventive apparatus is useful for, e.g., loading individual film sheets into cassettes for professional-style cameras, in daylight. A cassette (53) is insertable into the lower region of a housing (50). A separating device (55) is disposed above the cassette (53), which separating device has a cavity (90) for accommodating a stack of sheet film sheets. The top of the cavity (90) can be closed off by a light protection slide (91). A disk-shaped separating organ (112) is disposed above a lower light protection slide (116) of the separating device (55), which separating organ (112) is displaceable, e.g. by rotation. If one opens the lower light protection slide (116) of the separating device (55) in tandem with the light protection slide (57) of the cassette (53), the separating organ (112) separates out the bottommost film sheet of the stack, whereby the sheet falls into the cassette (53). After the light protection slides (116, 57) are closed, the now loaded cassette (53) can be removed. A container (51) with a light protection slide (70) is provided, for loading the stack of sheet film into the cavity (90) of the separating device (55) in daylight. This container (51) is insert…
