Abstract
A device for consecutively numbering photocopies produced by a conventional zerographic photocopy machine. A multiple section chase is placed on a transparency which is to be photocopied and carries a counter head which provides a numerical display. The chase also carries a photocell which sense the light emitted each time the light bar of the photocopier is swept past the transparency to produce a copy. The output signal from the photocell is used to increment the count state of the counter each time a copy is made. The numerical display is copied along with the transparency so that the successive photocopies made by the machine are imprinted with sequential numbers. The chase sections have a dovetail tongue and groove construction which allows the chase to be properly sized and also permits the counter head to be located at any desired position and orientation the chase.
