FILM SUPPORT AND TRANSPORT APPARATUS

摘要

Apparatus for supporting an elongated web of film transparency material in a reel-to-reel arrangement at a projection station in a film viewing device. Film material is selectively transported from one reel to the other past the projection station by both a manual and a powered drive arrangement. The film material is supported for selective positioning at the projection station in a direction transverse to the direction of film travel without interrupting the drive arrangement.
