ABSTRACT:
A self-supporting plate for holding photographic slides includes a unitary plate having a plurality of depressions spaced apart in lateral and longitudinal relationship and surrounded by two side partition walls and two end partition walls and having a substantially flat bottom wall. Each depression is adapted to receive a photographic slide therein. The self-supporting plate further comprises projections provided on and along part of the opposite side surfaces of the side partition walls, the projections being adjacent to one of the end partition walls in parallel spaced relation to the flat bottom and projecting inwardly of each depression. A groove is provided in the flat bottom of the depression between the mutually opposing projections of each depression, with its opposite side partition walls positioned on the opposite sides of a line on the bottom wall of the depression in parallel thereto. The line is coincident with a line interconnecting the front ends of the mutually opposing projections, as viewed in a direction to insert a photographic side. This arrangement ensures the holding of photographic slides, and also facilitates the insertion of a photographic slide into each depression.
