Abstract
An automatic photographic paper cutter cuts photographic prints from a roll of photographic paper which bears indicia indicating the location of desired cuts. The automatic photographic paper cutter has an improved indicia sensing system which includes a plurality of indicia sensors, each positioned to sense indicia on a different portion of the photographic paper. Prior to automatic operation of the paper cutter, an indicia bearing portion of the photographic paper is oscillated back and forth past the plurality of the indicia sensors. One of the sensors which provides an acceptable output signal is selected, and subsequent operation of the photographic paper cutter is controlled in response to signals from the selected sensor.
