ABSTRACT:
In contrast to standard microfiche devices in which discrete areas of information storage are provided in an x-y array, a scrolling microfiche includes a plurality of parallel rows of information storage areas in which, in at least one of the rows, a plurality of information storage areas contain information which bridges from one area to the next and completes the information stored from one area to the next so that the fiche may be scanned and an area may be read without the observation of frame divisions between frames. The fiche is produced by photographic processes. In one embodiment the process includes the generation of original elongate strip artwork, laying out the strips with respect to a rotary camera, reproducing each strip as a separate row on microfiche film, repeating laying out and reproduction as necessary for completion of the story of the fiche, and subsequent cutting operations and the like to produce a scrolling microfiche. In another embodiment, the original artwork is generated as individual plats which are reproduced on film as other, secondary, originals. The secondary originals are then microcomposed and reproduced with pagenating from area-to-area so as to reproduce the artwork in a reduced form which is equivalent to the elongate strips of the first embodiment. The process includes repeating microcomposing and reproduction, with pagenating, as necessary for completion of the story, on a microfiche structure, so that each row of the microfiche contains a portion of the story. The result is, again, a scrolling microfiche.
