Abstract
A magazine is provided for receiving, containing and dispensing a plurality of film cartridges in a desired sequential order. The magazine includes a disk shaped core and a shell. The core includes a plurality of cavities for receiving the cartridges, while the shell includes first and second spaced panels and supports the core for relative rotation between the panels. The panels cover the cartridges in the cavities, but also include apertures for selectively providing access to individual cavities by controlled rotation of the core in the shell. The cavities are arranged in a spiral in the core, and the apertures are elongate radial slots dimensioned for alignment with one cavity in the spiral after another, but only one cavity at a time.
