Abstract
Abstract A transport mechanism for open or closed flap diskettes is provided wherein the diskettes are singulated and withdrawn from the bottom of a stack of diskettes disposed in a hopper, transported to a work station where the diskette is duplicated and tested, then withdrawn from the work station and deposited in one of several bins depending upon the results of testing.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.

Claim 1
Independent Claim
246 words
In combination with a hopper for receiving a plurality of diskettes in stacked relationship, said hopper having front and rear containment walls, means for supporting a stack of diskettes in said hopper including first, second and third support means, each support means having a support surface, said first support means being located at the front of said hopper and having a support surface set below the front containment wall to define a front slot therebetween, said second support means being located at the rear of said hopper and having a support surface set below the rear containment walls to define a rear slot for receiving the edge of a diskette therethrough, the support surface of said third support means being located below and extending to the rear of the support surface of said first support means; means aligned with said front slot for engaging and rearwardly pushing the bottom diskette from beneath said stack through said rear slot until the front edge of said diskette falls from the support surface of said first support means onto the support surface of said third support means; and a diskette transport mechanism for transporting a diskette supported upon said second and third support means to a work station, said mechanism including a clamp for engaging a diskette supported on the support surfaces of said second and third support means, and means for moving said clamp to transport the lowermost diskette beneath said first support means to a work station.
Claim 2
Dependent Claim
246 words
In combination with a hopper for receiving a plurality of diskettes in stacked relationship, said hopper having front and rear containment walls, means for supporting a stack of diskettes in said hopper including first, second and third support means, each support means having a support surface, said first support means being located at the front of said hopper and having a support surface set below the front containment wall to define a front slot therebetween, said second support means being located at the rear of said hopper and having a support surface set below the rear containment walls to define a rear slot for receiving the edge of a diskette therethrough, the support surface of said third support means being located below and extending to the rear of the support surface of said first support means; means aligned with said front slot for engaging and rearwardly pushing the bottom diskette from beneath said stack through said rear slot until the front edge of said diskette falls from the support surface of said first support means onto the support surface of said third support means; and a diskette transport mechanism for transporting a diskette supported upon said second and third support means to a work station, said mechanism including a clamp for engaging a diskette supported on the support surfaces of said second and third support means, and means for moving said clamp to transport the lowermost diskette beneath said first support means to a work station.
Claim 3
Dependent Claim
55 words
The apparatus of claim 1 wherein said clamp is adjustably mounted on a carriage, said carriage being mounted upon a pair of rails, said clamp being adjustably mounted for operation at either one of two positions, a first position for engaging an open flap diskette and a second position for engaging a closed flap diskette.
Claim 4
Dependent Claim
35 words
The apparatus of claim 1, said means for engaging and rearwardly pushing the bottom diskette from beneath said stack being actuated as a diskette is moved into the work station by said diskette transport mechanism.
Claim 5
Dependent Claim
76 words
The apparatus of claim 1, said means for engaging and rearwardly pushing the bottom diskette comprising a slide reciprocally mounted in front of said hopper, means biasing said slide to a position forward of said hopper and retracted from the lowermost diskette supported on the support surface of said first support means, and means for moving said slide against said means biasing said slide as said diskette transport mechanism deposits a diskette to the work station.
Claim 6
Dependent Claim
38 words
The apparatus of claim 1, and means projecting forwardly and downwardly from the front of said hopper for deflecting a diskette supported upon said third support means and carried by said diskette transport mechanism to a work station.
Claim 7
Dependent Claim
41 words
The apparatus of claim 1, said diskette transport mechanism including means for actuating said clamp to engage each diskette at the work station, transport the diskette to one of two or more bins, and deposit the diskette into a selected bin.
