Abstract A card-type item for random access storage and retrieval formed of a transparent photographic film card or sheet carrying a plurality of microimages and having a metallic stiffening clip along one edge, such as a vertical edge, of U-shape within which that edge of the card or sheet is disposed and to which is interlocked as by dimpling of the metallic clip. The outer edge of the clip is provided with notches in any desired code, such as binary, to identify each item by the coded notches and their cooperation with address plates or bars positioned to permit only a single card-type item to be withdrawn from a store of a plurality of items. The opposite ends of the clip are provided with extensions of different breadth to positively orient the item in upright position. The outer edge of the clip is also provided with a generally central extractor notch to receive an extractor head and with upper and lower register notches, at least one of which locates the item vertically and the other establishes the vertical axis. The stiffening clip is desirably of magnetic material for initial magnetic movement of an addressed item from the store.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
78 words
An edge-stiffening clip for card-type microfiche comprising: an elongated magnetic member substantially U-shaped in cross section to have its legs disposed on opposite sides of an edge of the film; means on said member for mechanically engaging an a extractor therewith; a plurality of identifying coding notches in the bight edge of said member; and register notches at opposite sides of said identifying notches adapted to cooperate with register surfaces to index the clip in a delivered position.
Claim 2
Dependent Claim
78 words
An edge-stiffening clip for card-type microfiche comprising: an elongated magnetic member substantially U-shaped in cross section to have its legs disposed on opposite sides of an edge of the film; means on said member for mechanically engaging an a extractor therewith; a plurality of identifying coding notches in the bight edge of said member; and register notches at opposite sides of said identifying notches adapted to cooperate with register surfaces to index the clip in a delivered position.
Claim 3
Dependent Claim
49 words
The clip defined in claim 1 in which one of said register notches is substantially V-shaped to cooperate with a rounded surface to index the clip axially and the other of said register notches presents a surface to locate the axis in rotation relative to the first register notch.
Claim 4
Dependent Claim
29 words
The clip defined in claim 1 in which said extractor engaging means comprises a notch in the bight of said clip substantially centrally thereof for interlocking with the extractor.
Claim 5
Dependent Claim
35 words
The clip defined in claim 1 including end extensions on said clip of different breadths adapted to cooperate with a restrictive notch receiving only one of them whereby to orient the clip end for end.
Claim 6
Dependent Claim
40 words
A card-type item for random access information storage and retrieval comprising a microfilm card having the clip of claim 1 secured to an edge thereof with the edge of the microfilm card received between the sides of the U-shaped clip.
Claim 7
Dependent Claim
41 words
The card-type item of claim 5 in which said microfilm card edge is provided with perforations within the clip and at least one side of the clip is dimpled inwardly into the perforations to interlock the clip and the microfilm card.
Claim 8
Dependent Claim
27 words
The card-type item defined in claim 6 in which both sides of the U-shaped clip are dimpled inwardly to meet within the perforations through the microfilm card.
Claim 9
Dependent Claim
20 words
The card-type item defined in claim 7 in which said opposite side dimples are spot-welded together within the card perforations.
Claim 10
Dependent Claim
87 words
The card-type item defined in claim 5 in which: said extractor engaging means comprises a notch in the bight of the clip substantially centrally thereof for interlocking with the extractor; one of said register notches is substantially V-shaped to cooperate with a rounded surface to index the item axially and the other of said register notches presents a surface to locate the axis in rotation relation to the first register notch; and end extensions on said clip of different breadths for orienting the item end for end.
