The
above monster machine which is equipped with whirring motors, blinking
lights, prisms and cameras ladies and gentlemen, is the genealogical
limb of the family tree of our current copy machines and scanners.
Indeed, the genealogical tree for the "Photostat" can be attached to the
Xerox family tree. Fascinating! In a nutshell: The document to be
copied was photographed by one of the on board cameras in this monster
machine. A prism reversed the image which was printed on photographic
paper which was fed from a huge roll of photo sensitive paper.
