ABSTRACT:
Apparatus for positioning exposed and developed photographic roll films in a copying machine has a base which is formed with an exposure window and supports a removable cover, an advancing roll for photographic films, a first set of claws which can enter the perforations of a section of a roll film when the section is inserted and moved lengthwise by hand, and a second set of claws which can be used to position manually inserted webs of different films film webs which are bonded to data-carrying strips. The cover thereby retracts or depresses the first set of claws so that they cannot interfere with automatic transport of roll films. The claws of the second set are held in retracted positions by a removable insert which carries the first set of claws and the advancing roll and which is replaceable by a second insert when the apparatus is to position manually inserted different films which are bonded to data carrying strips. The second insert has apertures through which the claws of the second set extend so that they can enter the perforations of such different films.
