ABSTRACT:
Disclosed is a picture viewer for viewing a stack of pictures sequentially through a viewing window. The picture viewer comprises a housing member, a slider member, a bias means for urging the stack of pictures against the viewing window, and an exchange means for sequentially changing the picture that is presented at the viewing window. 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.
