ABSTRACT OF THE DISCLOSURE A picture viewer is disclosed for the alternate exposure of individual rectangular sheets from a pile of sheets. It comprises an enclosure having a viewing window and a compartment with sufficient depth to accommodate such a pile, one end of the compartment being disposed at the window to display a sheet through the window, another side of the compartment having an access opening, and means permitting separation of one sheet from one end of the pile and adding it to the pile at the other end thereof. Such means includes: pile support means opposite the viewing window and pile suppression means adjacent the window, a separator bar extending parallel to congruent edges of the sheets in the pile and having a first edge opposite the window and a second edge adjacent thereto, the separator edges being spaced from each other such that removal and insertion slots are defined between respective separator edges and compartment walls confining the access opening. The pile support means and the pile suppression means are spaced from each other by a distance exceeding the distance by which the separator edges are spaced from each other, the separator bar further having a first oblique face confronting the congruent sheet edges and a second oblique face opposite the first face. Both of the separator faces extend between the first and the second separator edge, whereby a sheet to be separated from the pile and thrust edgewise against the separator is deflected away from the pile permitting it to be fed through one of the slots and whereby a sheet when added to the pile after being fed through one of the slots will be retained by the separator bar at its edge adjacent the latter.
