Abstract
The photoelectric scanning device for original images contained on a photographic film has a film platform for the film, for temporarily holding the original images contained on the film in a respectively defined scanning position; a light source for illuminating the respective original image in the scanning position; a photoelectric converter for receiving light being transmitted through the respective original image in the scanning position, and for converting the received light into electrical scanning signals in a two-dimensional and pixel-by-pixel manner; an optical member for imaging the respective original image in the scanning position onto the photoelectric converter; and an electronic member for controlling the photoelectric converter and for reading out the electrical scanning signals which are generated by said photoelectric converter. A film notching device is disposed at the film platform in the region of the scanning position for punching or stamping a positioning notch into the side margin of the film at a location associated with the original image respectively in the scanning position. The integration of the film notching device directly into the scanning device r…
