Abstract

Abstract A microform information storage unit for use with a microform reading apparatus is disclosed. The unit comprises a plurality of microform information storage members pivotally coupled along a common edge of a first body and a plurality of index members integrally coupled with the microform storage members in predetermined alignment with the microform members, the index members being integrally coupled along a common edge to an opposite edge of the first body whereby the index members and the microform members are adapted to be folded along the coupling edges. The index members have recorded thereon indicia for randomly retrieving information from the microform members when the indicia are aligned with reference means of the reading apparatus.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 238 words
In combination, a microform viewing apparatus for holding and displaying a microform, said apparatus including reference means secured thereto; and a microform information storage unit including a plurality of generally flat microform information storage members having information recorded thereon in predetermined discrete areas of the members, said information storage members pivotally coupled along a common edge to an edge of a first body; a plurality of generally flat index members coupled with said microform storage members in predetermined alignment with said microform members, said index members integrally coupled along a common edge to an opposite edge of said first body whereby said index members and said microform members are adapted to be folded about the coupling edges; said index members having recorded thereon in predetermined discrete areas visible indicia to identify corresponding recorded information on said storage members, said indicia lying on said index members in substantially the same geometric array as said corresponding recorded information lies on said storage members, said index members oriented with respect to said recorded information for displaying and viewing particular information on said storage members when indicia on a particular index member relating to particular information on a microform storage member corresponding to said particular index member is aligned with said reference means on the microform viewing apparatus, said particular index member and corresponding microform storage member being rotated and aligned in substantially the same plane for viewing with said viewing apparatus.
Claim 2
Dependent Claim 238 words
In combination, a microform viewing apparatus for holding and displaying a microform, said apparatus including reference means secured thereto; and a microform information storage unit including a plurality of generally flat microform information storage members having information recorded thereon in predetermined discrete areas of the members, said information storage members pivotally coupled along a common edge to an edge of a first body; a plurality of generally flat index members coupled with said microform storage members in predetermined alignment with said microform members, said index members integrally coupled along a common edge to an opposite edge of said first body whereby said index members and said microform members are adapted to be folded about the coupling edges; said index members having recorded thereon in predetermined discrete areas visible indicia to identify corresponding recorded information on said storage members, said indicia lying on said index members in substantially the same geometric array as said corresponding recorded information lies on said storage members, said index members oriented with respect to said recorded information for displaying and viewing particular information on said storage members when indicia on a particular index member relating to particular information on a microform storage member corresponding to said particular index member is aligned with said reference means on the microform viewing apparatus, said particular index member and corresponding microform storage member being rotated and aligned in substantially the same plane for viewing with said viewing apparatus.
Claim 3
Dependent Claim 17 words
The combination of claim 1 wherein said first body comprises an index member having indicia formed thereon.
Claim 4
Dependent Claim 22 words
The combination of claim 1 including a sheet of protective material positioned between said microform members for inhibiting damage to said members.
