Abstract: Articles are transported from one position to another by being disposed in trays, which are carried within a portable magazine. The trays are automatically unloaded in sequence from the magazine and transported to a position in which the articles in the tray may be removed therefrom. The unloaded tray is then returned to the magazine and the next of the trays is removed from the magazine. The apparatus includes coding means on the magazine to indicate the status of the articles within each of the trays in the magazine.
