ABSTRACT:
In a color-slide duplicator having a housing containing a light source which illuminates an opening in a housing wall, and a support for a camera above the housing for photographic reproduction of a slide to be duplicated; an assembly for supporting the slide comprises a carrier plate releasably and adjustably secured by magnets to the housing wall so as to span the illuminated opening which registers, at least in part, with an aperture in the carrier plate, and first and second parallel guide bars having undercut, beveled edges facing toward each other and being arranged on the carrier plate at opposite sides of the aperture in the latter, with one of the guide bars being movable laterally and resiliently urged in the direction toward the other guide bar, such guide bars being included in a quick-release mechanism by which the slide to be duplicated is positioned and held against the carrier plate over the aperture therein. In the case of a slide having a rigid frame, opposing side edges of the frame can be directly engaged by the beveled guide bar edges. When the slide is an unmounted flexible film, a bearing and masking plate with an aperture registering, at least in part, with the carrier plate aperture is engaged, at opposing side edges, by the beveled guide bar edges to be urged thereby against the carrier plate with the flexible film held flat between the carrier and bearing plates.
