ABSTRACT:
A diazo copy machine comprises a roll of diazo sensitized copy paper cradled between a pair of drive rollers above an exposure apparatus. The copy machine is activated by insertion of an original tracing sheet whereupon the copy paper and original are automatically fed in superimposed relation into the entrance of the exposure apparatus, with the leading edge of the copy paper being advanced by a programmable amount relative to the leading edge of the original. Upon exiting the exposure apparatus the superimposed sheets are directed to an automatic sheet separating apparatus which deflects and feeds the copy paper along a downward path to a developer and carries the original along an exit path out of the front of the copy machine. In the event that the two superimposed sheets both inadvertently enter the downward path, a fail-safe mode of operation is initiated for redirecting both sheets along the exit path.
