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.

Photographic image acquisition device

A processing arrangement for web shaped material (M) wound onto reels before and after processing includes a processing station (B) for the material, associated transport mechanism (T) for transporting the material through the processing station, an unwind arrangement (U) for the automatic feeding of material to be processed from on an unwind reel (S) located in an unwind position (pU) to the processing station, a windup arrangement (W) for the automatic feeding and winding up of processed material leaving the processing station onto a windup reel (S) located in a windup position (pW), and a common reel carousel (K) for receiving at least three windup reels (S) and unwind reels (S). The reel carousel transports the reels (,) removably mounted thereon cyclically and stepwise into the unwind position (pU), the windup position (pW) and at least one exchange position (pR) so that an unwind reel (S) emptied after unwinding of the material to be processed (M) after its further transport into the windup position (pW) can take over the role of a windup reel (S) and that in the at least one exchange position (pR) a windup reel (S) containing processed material can be removed from the reel carousel (K) and replaced with a new unwind reel (S) containing material to be processed. The processing arrangement is especially suited for the treatment or processing of photographic rolled up material and facilitates and simplifies the operation in that the exchange of the material reel is possible in one operation step and at one location of the processing arrangement.
