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 requires only one positioning process of the films or the images contained on the films. Thus, the required apparatus cost and the technical control needed for the positioning are substantially reduced when compared to separate scanning and notching devices. Furthermore, the scanning device thus requires substantially less room than two separate devices, which is particularly significant when arranging the device within a copier device.
