Abstract A photoelectric film scanning device is provided with a film entrance, a film exit, a film transport path connecting the film entrance and the film exit, transport members for transporting a film to be scanned along the film transport path from the film entrance to the film exit, the film being provided at the film entrance, a scanning platform being arranged in the film transport path for positioning the film during scanning, an exposure device for illuminating the film with a measuring light about the scanning platform, a photo-electric converter for receiving the measuring light being transmitted by the film and for converting the measuring light being transmitted by the film into respective electrical signals in a pixel-by-pixel manner, and an optics for guiding the measuring light being transmitted by the film to the converter. The scanning platform comprises a rotor, said rotor being provided in a rotatably adjustable manner about an axis being substantially parallel to a longitudinal direction of the film transport path. The circumference of the rotor includes at least two film mask arrangements for different formats of the film, said film mask arrangements being provided at a circumference of the rotor, wherein the film mask arrangements are selectively insertable into the film transport path by means of a rotational adjustment of the rotor. A film feeding device is arranged in front of the film entrance, said film feeding device for directing a film strip being manually or electrically inserted at a film entrance position to a film entrance, said film feeding device further including an decoiling device for automatically removing a film contained within a film cartridge from said cartridge and for guiding said film to the film entrance.
