Abstract
Abstract The present invention relates generally to improvements in holders for microfilms and the like and more particularly to novel, readily portable holders equipped with magnetic file cards and magnets to effect fanning of said cards. The portable file or holder disclosed herein includes an elongate base section, laterally spaced file card supporting rods adjacently traversing said base section, and a plurality of generally upright file cards traversed and supported by said rods. The cards are equipped with magnetic means located along the lower half of opposite upright margins thereof. End wall sections extend upwardly from opposite extremities of the elongate base section and support magnets in the vicinity of the magnetic means carried by the cards. Closure panels extend upwardly from the vicinity of the opposite elongate margins of the base section and may be laterally shifted to facilitate positioning the cards in fanned relation or in compact juxtaposition.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
143 words
A readily portable holder for microfilms and the like including an elongate closure base section, a removable magnet support member superimposed over said elongate closure base section laterally spaced file card supporting rod means adjacently traversing said base section and over said removable magnet support member, a plurality of generally upright file cards traversed and supported by said rod means, magnetic means carried by opposite upright margins of said cards and located in the vicinity of the lower half of said cards, end closure sections extending upwardly from the opposite extremities of said elongate closure base section, magnets supported by said removable magnet support member adjacent said end closure sections in the vicinity of said magnetic means, the area between adjacent file cards serving to accomodate microfilms, and relatively, laterally shiftable closure sections extending upwardly from opposite elongate margins of said base section.
Claim 2
Dependent Claim
143 words
A readily portable holder for microfilms and the like including an elongate closure base section, a removable magnet support member superimposed over said elongate closure base section laterally spaced file card supporting rod means adjacently traversing said base section and over said removable magnet support member, a plurality of generally upright file cards traversed and supported by said rod means, magnetic means carried by opposite upright margins of said cards and located in the vicinity of the lower half of said cards, end closure sections extending upwardly from the opposite extremities of said elongate closure base section, magnets supported by said removable magnet support member adjacent said end closure sections in the vicinity of said magnetic means, the area between adjacent file cards serving to accomodate microfilms, and relatively, laterally shiftable closure sections extending upwardly from opposite elongate margins of said base section.
