Abstract A random access store for cards, file folders and the like, in which the folders are stacked face-to-face. The folders are optically edge-coated and sensed simultaneously by a plurality of moving carriages, driven by a single cable, which continuously compares the sensed code to the command code and ejects the desired folder. The optical reader senses rectilinearly (along the same line as the light source) and the coded signal is automatically negated from mis-positioned folders. Folder alignment regardless of packing density is provided by magnetic clutching in cooperation with an array of folder guiding slots. Manual entry of the file folders into the store is random and may take place simultaneously with the automatic withdrawal. Towards this end, a feed-through access is provided which automatically gates and raises the magnetic clutches to permit ejection of the desired folder. Further refinements described include ejected folder collection; automatic input; a memory adjunct; and remote signalling.
A random access storage system of the type where edge-coded items are stacked at random in juxtaposed edge-aligned attitudes in a plurality of vertically stacked racks comprising: a plurality of assemblies for scanning the code markings on item edges; means for guiding each of said assemblies along a path adjacent the coded edges of the items in one rack; and means for simultaneously and synchronously traversing said assemblies relative said items in each of said racks, said means comprising a single motor driven drum, and a single continuous cable wrapped about said drum and affixed to each of said assemblies.

Claim 3
Dependent Claim
