Abstract
A photographic printer including a lamp, a film transport positioned over the lamp and coacting with the lamp to define an optical axis, a photographic paper drive positioned over the film transport, and a lens deck positioned between the film transport and the photographic paper drive. The lens deck comprises a plurality of lens carriages mounted at respective levels on the optical axis for linear movement in parallel directions generally normal to the optical axis. A plurality of laterally spaced lens assemblies are positioned on each carriage at different levels with respect to the optical axis. The various carriages are selectively moved along their respective linear paths to bring a lens assembly corresponding to a particular film size and a particular print size into alignment with the optical axis.
Claims25
A photographic printer including a lamp, a film transport positioned over the lamp and coacting with the lamp to define an optical axis, a photographic paper drive positioned over the film transport and a lens deck positioned between the film transport and the photographic paper drive, characterized in that the lens deck includes a plurality of lens carriages mounted at respective levels on the optical axis for translatory movement in parallel directions generally normal to the optical axis and each including a plurality of laterally spaced lens assemblies movable in response to the translatory movement of the respective lens carriage successively into alignment with the optical axis.
A photographic printer including a lamp, a film transport positioned over the lamp and coacting with the lamp to define an optical axis, a photographic paper drive positioned over the film transport, and a lens deck positioned between the film transport and the photographic paper drive, characterized in that:
- the lens deck comprises at least one carriage mounted for translatory movement in a direction generally perpendicular to the optical axis and including a plurality of lens assemblies mounted on the carriage at laterally spaced locations and at various levels with respect to the optical axis;
- and
- the carriage is movable translatory to a park position in which all of the lens assemblies are on one side of the optical axis successively toward the other side of the optical axis so as to bring successive lens assemblies into alignment with the optical axis at successive levels with respect to the optical axis.
For use with a photographic printer including a lamp, a film transport positioned over the lamp and coacting with the lamp to define an optical axis, a photographic paper drive positioned over the film transport, and a lens deck positioned between the film transport and the photographic paper drive, a method of providing a lens assembly corresponding to particular film sizes and particular print sizes, the method comprising:
- providing at least one lens carriage arranged for translatory movement along a linear path intersecting the optical axis in a generally perpendicular fashion;
- positioning a plurality of lens assemblies on the carriage at laterally spaced locations and at various levels with respect to the optical axis;
- and
- moving the carriage translatorily along the path to bring successive lens assemblies into alignment with the optical axis at successive levels with respect to the optical axis to provide lens assemblies corresponding to various film sizes and various print sizes.
