Abstract
Abstract A magnifying, illuminated, and shuttle-operated print or picture viewer combined with picture-storing means, hereinafter called a picture viewer, that comprises a housing provided with a shuttle for simultaneously feeding pictures from the bottom of a stack by a rearward portion of the shuttle to a viewing position, and pictures in the latter position into a pile on an extensible tray by the forward edge of the shuttle. A weighted picture-storing member is provided to flatten the pictures fed from the stack, successively and one at a time, so the feed of pictures is efficiently carried out.
