Abstract: Automated apparatus for applying integrated circuits to a circuit board in which the integrated circuits are fed to the apparatus through the open end of a tubular magazine which holds them in a linear array, and which is positioned in registry with a feeding aperture of the apparatus. By this invention, a casing is provided for holding a plurality of the magazines in side-by-side relation, with the first of the magazines of the plurality occupying the position of registry with the feeding aperture. A spring loaded platen member is provided for biasing the magazines toward the position of the first magazine, so that when the first magazine is emptied of its integrated circuits it may be removed from the casing, and another of the tubular magazines moved by the resilient means into the position of registry.
