Mechanism for positioning film into a scanning position in an internal drum laser scanner assembly

摘要

An assembly for positioning a piece of photosensitive film into a scanning position on a curved film platen and an internal drum scanner assembly. The film platen is defined by a film feed edge and a film stop edge. An alignment mechanism is positioned proximate the film stop edge and a feed mechanism is positioned proximate the film feed edge. The feed mechanism operates to feed the leading edge of the film from the film feed edge along the film platen towards the film stop edge alignment mechanism, and wherein when the photosensitive film is in the scanning position, the photosensitive film is compressed against the curved film platen in alignment between the alignment mechanism and the feed mechanism. A centering mechanism is also provided.
