Abstract
Microfiche cards and the like are held in a file enclosure between file-segregator cards. The segregator cards are shaped to fit on and slide along longitudinal rails. To promote fanning of the segregator cards when they are compressed in a particular way, they have added thickness in a zone near their bottom edges. Two independently adjustable compressors are provided, one above and one below the added-thickness zone. By manipulation of the compressors a user can fan the file to a desired extent, controlling the fraction of the group of segregator cards which fans, and the angle between the adjacent fanned segregator cards, or can maintain the file tightly closed.
Claims10
A variable-visibility information storage and retrieval system for holding and displaying information cards between file segregators, comprising;
- a multiplicity of generally planar file segregators having top, bottom and side edges;
- enclosure means for supporting and retaining said file segregators in a row, one in front of another, said enclosure means having front and back ends;
- engaging means for releasably securing said file segregators to said enclosure means, said engaging means comprising a first pair of parallel rails mounted to the enclosure means longitudinally with respect to the row of segregators, and notches defined in the edges of said segregators releasably and slidingly engaging said rails;
- and
- compression means for controllably bending and fanning said file segregators, said compression means comprising separate, spaced lower and upper independently adjustable compressors mounted to said enclosure means and controllably compressing said segregators together against one end of said enclosure means along a first line near said bottom edges and along a second line more distant from said bottom edges, respectively.
A variable-visibility information storage and retrieval system for holding and displaying information cards between file segregators, comprising:
- a multiplicity of generally planar resilient file segregators having top, bottom and side edges, said segregators being of greater effective thickness in a transverse zone spaced from their bottom edges than elsewhere outside said zone;
- enclosure means for supporting and retaining said file segregators in a row, one in front of another, said enclosure means having front and back ends;
- and
- compression means for controllably bending and fanning said file segregators, said compression means comprising separate, spaced lower and upper independently adjustable compressors mounted to said enclosure means between the row of segregators and one end of the enclosure means and controllably compressing said segregators together against the opposite end of said enclosure means along a first line intermediate said bottom edges and said zone, and along a second line intermediate said first line and said top edges, respectively.
