Mechanism for positioning film into a scanning position in an internal drum laser scanner assembly
First Claim
1. An assembly for positioning a piece of photosensitive film having a leading edge and a trailing edge into a scanning position on a curved film platen in an internal drum scanner assembly, wherein the film platen is defined by a first curved edge, a second curved edge, a film feed edge, and a film stop edge, the assembly comprising:
- a first slider block assembly movable relative to the curved film platen;
a second slider block assembly movable relative to the curved film platen and spaced from the first slider block assembly a distance less than a width of the leading edge of the piece of photosensitive film; and
a feed mechanism positioned proximate the film feed edge, for feeding the photosensitive film along the curved film platen;
wherein the photosensitive film is fed by the feed mechanism, such that the leading edge of the film moves from a location proximate the film feed edge towards the film stop edge of the curved film platen, and wherein when the photosensitive film is in the scanning position the leading edge of the photosensitive film contacts the first slider block assembly and the second slider block assembly, and the trailing edge of the photosensitive film contacts the feed mechanism, and wherein this contact with the first and second slider block assemblies and the feed mechanism causes the photosensitive film to conform to the curved film platen in alignment between the first slider block assembly and the second slider block assembly, and the feed mechanism.

Abstract
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.

17. An assembly for positioning a photosensitive film having a leading edge and a trailing edge into a scanning position on a curved film platen in an internal drum scanner assembly, wherein the film platen is defined by a first curved edge, a second curved edge, a film feed edge, and a film stop edge, the assembly comprising:
-
a first slider block assembly; a second slider block assembly spaced from the first slider block assembly a distance less than a width of the leading edge of the photosensitive film; a feed mechanism positioned proximate the film feed edge, for feeding the photosensitive film along the curved film platen; wherein the photosensitive film is fed by the feed mechanism, such that the leading edge of the film moves from a location proximate the film feed edge towards the film stop edge of the curved film platen, and wherein when the photosensitive film is in the scanning position the leading edge of the photosensitive film contacts the first slider block assembly and the second slider block assembly, and the trailing edge of the photosensitive film contacts the feed mechanism, and wherein this contact with the first and second slider block assemblies and the feed mechanism causes the photosensitive film to conform to the curved film platen in alignment between the first slider block assembly and the second slider block assembly, and the feed mechanism; and a centering mechanism movably coupled to the film platen which centers the photosensitive film into the scanning position. - View Dependent Claims (18, 19, 20)
