Abstract
Abstract Apparatus for storing documents includes a rectangular housing having first and second openings on a front wall and first and second spaced manifolds mounted on the back wall in horizontal alignment with the openings. A vertically movable rectangular rack is mounted in the housing, the rack having a plurality of pockets whose entrance may be aligned with the openings. Also, each pocket communicates with one of a plurality of sets of holes in the rack, each set being alignable with the manifolds. With vacuum pressure supplied to the first manifold fluid flows through the first opening, through a pocket, and through a corresponding set of holes. Thus, a document inserted into the first opening is drawn into a pocket of the rack. The rack may be stepped along and all of its pockets may be filled with documents. With pressure applied to the second manifold fluid is injected through a set of holes into a pocket and the fluid flows out through the second opening. With documents in the rack, if the rack is stepped along all of the documents stored may be ejected.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
152 words
Apparatus for storing documents, comprising: a. a housing having an opening; b. a rack located in the housing and having a plurality of parallel pockets for storing documents, the rack including a number of plates, a plurality of spacers, and means for fixing the spacers to the plates to provide the pockets; c. means for moving the rack to successively align each of said pockets with the opening; and d. first fluidic means for moving documents, in pockets brought into alignment with the opening, through the opening; said housing including, on one side of the opening, an internal projection having a curved end and, on the other side of the opening another internal projection having a similarly curved end, each of the plates on the rack having a similarly curved end, adjacent plates being in near contact with the curved ends of the projections when a pocket is aligned with the opening.

Claim 3
Dependent Claim
45 words
Apparatus as defined in claim 1 wherein each spacer includes a set of holes, and wherein said fluidic means includes means for injecting fluid to any one of the sets of holes when the pocket with which the set communicates is aligned with the opening.
Claim 4
Dependent Claim
61 words
Apparatus as defined in claim 2 wherein said means for injecting fluid includes a hole in the housing, a pump, and means for directing fluid from the pump through the hole, the hole being located so as to communicate with said any one of the sets of holes when the pocket with which the set communicates is aligned with the opening.
Claim 5
Dependent Claim
31 words
Apparatus as defined in claim 2 wherein said pump is reversible and in a vacuum mode of operation draws documents inserted into the opening into a pocket aligned with the opening.
Claim 6
Dependent Claim
32 words
Apparatus as defined in claim 1 wherein said housing includes another opening and second fluidic means for moving documents inserted through said another opening into a pocket aligned with said another opening.
Claim 7
Dependent Claim
30 words
Apparatus as defined in claim 5 wherein said rack includes: a number of plates; a plurality of spacers; means for fixing the spacers to the plates to provide the pockets.
Claim 8
Dependent Claim
46 words
Apparatus as defined in claim 6 wherein each spacer includes a set of holes, and wherein said first fluidic means includes means for injecting fluid to any one of the sets of holes when the pocket with which the set communicates is aligned with said opening.
Claim 9
Dependent Claim
42 words
Apparatus as defined in claim 7 wherein said second fluidic means includes means for drawing fluid from a pocket aligned with said another opening, the fluid being drawn through a set of holes communicating with the pocket aligned with said another opening.
