Abstract
A scanning device for the point-by-point photoelectric scanning of a photographic film includes a transport arrangement for the transporting of the film along a transport path through a scanning zone, a guide arrangement for the guiding and positioning of the film in the scanning zone, an illuminating arrangement for exposing the film in the scanning zone with measuring light, a photoelectric converter arrangement for converting the measuring light transmitted through the film into corresponding electrical signals, and optical means for guiding the measuring light transmitted through the scanned film onto the photoelectric converter arrangement. The guide arrangement includes a motor-driven, selectively adjustable, moveable platform, positioned in the scanning zone, for the mechanical guiding and positioning of films of at least two different formats. The automatic adjustment of the moveable platform is effected by a sensor for detecting the format of the film to be scanned as well as a control cooperating with the sensor. The scanning device includes a first entry for the in line supply of films to be scanned from an upstream film processor as well as a second entry for the manual feeding of films. A severing arrangement is provided upstream of the first entry which for severing the leader card connected with the film to be scanned. After removal of the leader card, the film is guided into the first entry. The scanning device permits the processing of films of different formats and is well-suited for use in a digital photographic copier.
