Abstract
A photographic slide magazine is placed on a hub and rotates around its axis while the compartments containing slides pass over an opening through which the slides drop into a receiver. After unloading previously stored slides each compartment passes under a loading mechanism, which drops another slide into each of the emptied compartments. Loading and unloading operations are concurrent. A storage magazine with a clamping mechanism is used to pick-up the unloaded slides and to place slides in the loading mechanism.
