Abstract: A round tray for photographic transparencies has a bottom wall, a ring-shaped inner wall and radially extending partitions which are rigid with the two walls and define an annulus of compartments for transparencies. At least a portion of each partition resembles a wedge or sector whose width increases radially outwardly so that the parts of compartments between such portions have a constant width to thus prevent excessive changes in orientation of inserted transparencies. The transparencies may be yieldably held in the respective compartments by discrete leaf springs which are secured to a cover overlying the bottom wall and separably attached to the inner wall, or by bifurcated elastic parts of the partitions.
