Picture viewer

A picture viewer for the alternate exposure of individual rectangular sheets from a pile of sheets, comprising 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, means permitting separation of one sheet from one end of said pile and adding it to said pile at the other end thereof, said means including:

• pile support means opposite said viewing window and pile suppression means adjacent said window, a separator bar extending parallel to congruent edges of said sheets in said pile and having a first edge opposite said window and a second edge adjacent thereto, said separator edges being spaced from each other such that removal and insertion slots are defined between respective separator edges and compartment walls confining said access opening, said pile support means and said pile suppression means being spaced from each other by a distance exceeding the distance by which said separator edges are spaced from each other, the separator bar further having a first oblique face confronting said congruent sheet edges and a second oblique face opposite said first face, both said separator faces extending between said first and said second separator edge, whereby a sheet to be separated from said pile and thrust edgewise against said separator is deflected away from said pile permitting it to be fed through one of said slots and whereby a sheet when added to said pile after being fed through one of said slots will be retained by said separator bar at its edge adjacent the latter.
