Abstract
A stacking device is provided for rigid discs which have an interior aperture. An elongate registry member has cross sectional dimensions slightly less than the interior dimensions of the aperture in the discs. The registry member has a hollow interior and at least six circumferentially spaced axially elongate slots in the outer surface of the member. A pair of sets of elongate rack members are located in the alternating slots in the registry member. Each rack member has a plurality of outwardly directed teeth. The rack members of one set, designated set A, are movable both radially and axially with respect to the registry member. The rack members of the other set, designated set B, are movable radially with respect to the registry member. The sets of rack members of the present invention are operated to load discs in the following fashion. Set A is moved outwardly to receive a disc with set B recessed. Set A moves downwardly carrying the received disc, and set B moves outwardly to receive the disc from set A. Set A then moves inwardly, upwardly and outwardly to be in a position to receive the next disc. The process is repeated to load a plurality of discs, and is reversed to unload the discs.
