ABSTRACT:
Microfilm is converted into microfiche by feeding the film through a cutter, cutting the film into one or more frames, and then mounting the frame(s) upon a transparent microfiche base. The microfilm has a pair of adhesive strips along the top and bottom edge of its bottom surface for attaching the microfilm to the base. The microfiche base is mounted on a fiche deck by means of registration pins; lights are provided below the fiche deck for informing the operator where to place the frames on the base; and a margin grid having guide bars overlies the base to aid the operator in mounting the frames in precise alignment on the base. The film cutter removes a slice from the cut frames to aid the operator to mount the frames.
The microfiche is updated by mounting all "updatable" frames in the same row and pre-cut from each adjacent frame. A solenoid and its push pin are positioned beneath each updatable frame and a clearance opening for each push pin is located in the microfiche base. To update a microfiche, the proper solenoid is energized to remove one edge of the frame to be updated from the base, the frame is then completely removed, and a new updated frame is substituted for the outdated, removed frame.
