Abstract:
An apparatus for registering film in a drum scanner assembly comprising:a horizontally oriented concave curved film platen having first and second horizontal edge regions and third and fourth curved side edge regions connected between said first and second edge regions, said concave, curved film platen having a curved surface defining a curved film path from said first edge region to said second edge region; a plurality of slider assemblies having film engagement members mounted relative to said platen to engage film fed into said film platen, said film engagement members being independently slidable within said slider assemblies; wherein said plurality of slider assemblies include a first set having film engagement members for engaging a first film of a first crosswise dimension and a second set cooperating with said first set and having film engagement members for engaging a second film of a second crosswise dimension greater than said first crosswise dimension of said first film; and means for simultaneously moving said slider assemblies according to the size of film to be fed onto said film platen such that all of said film engagement members are aligned across said platen in a direction perpendicular to said film path; wherein as film is fed onto said film platen from said first edge region along said curved film path toward said second edge region, the leading edge of said film engages said film engagement members to move the members along the slider assemblies until the film is registered on the platen, the film being de-skewed during said movement.
