ABSTRACT:
A system for facilitating the handling of overhead projector transparencies on an overhead projector of the type including an upwardly facing projector platen. The system includes a frame assembly to provide a support surface adjacent the projector platen. A transparency storage cassette is supported on the support surface in alignment with the projector platen and generally includes a housing defining a closed chamber. An upwardly biased follower plate is mounted within the chamber to support a stack of transparencies. A door allows loading of the transparencies into the chamber. Between the door and the follower plate is a cam arrangement to move the follower plate downwardly against the bias when the door is moved to an open position to thereby facilitate the loading of the transparencies into the chamber. A transparency discharge slot is provided in the housing along the side adjacent the projector platen and opening in the top wall of the housing permits manual access to the top transparency in the stack to thus allow the top transparency to be slid from the stack out of the housing through the discharge slot to a projecting position on the projector platen.
