Abstract: A transport mechanism for open or closed flap diskettes is provided wherein the diskettes are singulated and withdrawn from the bottom of a stack of diskettes disposed in a hopper, transported to a work station where the diskette is duplicated and tested, then withdrawn from the work station and deposited in one of several bins depending upon the results of testing.The diskettes are supported in a hopper upon first and second support surfaces, the first being at the front of the hopper and slightly above the second. The lowermost diskette is moved rearwardly from beneath the stack until its front edge is deposited onto a third support surface below the first support surface, then engaged by a clamp and advanced beneath the first support surface to the work station.
