ABSTRACT:
A multislide holder and editor comprises a rectangular plate-like body having a plurality of rectangular slide-receiving pockets formed between two sets of parallel ribs disposed at right angles to one another. Upon insertion into its respective pocket each slide enters two spaced parallel open-ended side edge engaging channels, each channel comprising two spaced edge-engaging members. One of these edge engaging members comprises at least two longitudinally spaced portions with a gap between them, while the other cooperating member is disposed opposite this gap and is of not greater length than the gap, so that the entire body can be formed by a single molding operation with linearly-moving relatively simple mold parts. A cabinet for the holder and editor has a source of illumination in the cabinet door, and a plurality of the holders are mounted by channel members on the top and bottom inner wall to move parallel to the door in its open position, so that they can be positioned in front of the door for inspection and editing. The door can be readily removed to serve as a separate light source for viewing and editing.
