Abstract:
Photographic printers of versatile character are taught. Disclosed is a printer having a lens carrier assembly which includes at least one subassembly of shiftable lens boards adapted to be moved in and out of an operative position for photographic printing. The subassembly can be moved as a unit out of engagable relationship with power means for shifting the lens boards. The power means for shifting the lens boards is not moved with the subassembly. An alternate subassembly may then be moved into position for operation by the power means. Disclosed also is a composite lens carrier assembly which, as a complete unit, can be entirely removed from a printing apparatus to permit an alternate assembly to be inserted. Additionally disclosed is a new location for a shutter mechanism, at the window into a chamber for the light-sensitive print material. Further, there is disclosed a new negative holder assembly of removable and replaceable elements.
