Strip Storage Access Mechanism

This access mechanism is for a large capacity information storage device. Such is of the type which employs individual strips as the storage medium.

The individual strips are grouped in cells A which are suspended on the periphery of a bin B. Bin B is driven continuously at a constant rate by motor C. Cell carriage D is mounted parallel to bin B. Carriage D has a pair of arms E and F for grasping a cell and transporting it in the direction of the arrows to an access station G. Station G is capable of selecting any of the strips, extracting or storing desired information, and returning the strip to its original location. Carriage D then returns the cell to bin B. An identifying code is read off each cell by transducer H which transmits the code to comparator I. The identity code of a selected cell is also an input to comparator I.

When a comparison is made, clutch J is actuated to drive carriage D and pick the selected cell off bin B. Disk K rotates with bin D and has a plurality of studs, one for each cell. Fork L is secured to carriage D and rotates with it. Fork L engages a stud which corresponds to the selected cell and synchronizes the movement of carriage D with the movement of bin B. Thus, arms E and F intercept the selected cell.

Multiple cell carriages and access stations can be mounted around the periphery of the bin for overlapping access operation or for operation on independent channels.
