ABSTRACT:
A device for positioning the spool of a cartridge for a roll of photographic film. The film is provided with holes, at its end, that interact with catches attached to the spool. Detachment from, or attachment to, the spool, is only possible at a particular orientation of the spool. A shaft is provided which can be interlockingly connected with the spool in a predetermined orientation. A guide block is displaceable, being operative, directly or indirectly, for contacting with the shaft. It reorients the shaft to the desired position during displacement so that the film can be detached from the spool or attached to the spool.
