Illuminated billfold, portfolio, book and the like

Image Number 4 for United States Patent #6409357.

A page of printed information content between front and back covers is automatically illuminated when the covers are folded away from one another by a source of illumination affixed to at least one of the covers adjacent an edge surface thereof, while the other of the covers includes a notch in opposite position to overlie the source when the covers are folded closed, thereby retaining the page substantially flat--with electronic switch means serving to energize the illumination source only when the front and back covers are separated.
