The exchange means comprises: (a) a retentive element to hold one picture in the housing member when the slider member is moved out of the housing member and (b) a separator bar which pushes the remainder of the stack out of the housing when the slider member is moved out of the housing. To permit relatively smooth operation of the picture viewer, the bias means is mounted on the slider.

Abstract: A picture viewer having a housing to confine a pile of pictures, a slider to be withdrawn and returned to the housing, a viewing window, a pressure plate confronting the window, springs urging the plate toward the window, a retention strip to engage and strip off the picture at the end of the pile upon withdrawal of the slides, a separator strip to retain the pile as the one picture is stripped off, a slidable button on the housing to disable the springs and draw the plate away from the window, and a confining ledge on the slider also drawing the plate away from the window and independently of the slidable button.
