Abstract
A cartridge magazine is provided including a plurality of sleeves, each defining a pocket for containing a film cartridge, and a hub supporting the sleeves parallel to one another in a ring. Each sleeve defines a non-circular cross-section accommodating longitudinal movement of the cartridges through the sleeve, but blocking rotational movement of the cartridges in the sleeve. The sleeve, is open along one side, defining a slot for accessing cartridges from the exterior of the magazine. In certain applications, film in selected cartridges is advanced from the cartridge and through the slot without removing the cartridge from the magazine. According to other features, duplicate sections of the magazine are combined with the sleeves arranged in columns for increased capacity.
