ABSTRACT:
A motor driven camera back for instant film carrying machine readable indicia representative of parameters of the film. The back includes a pair of processing rollers driven by a motor between an initial spaced relationship and an operative pressure nip relationship and also in rotation in the operating relationship to process and discharge an exposed film unit from the back. A sensor and motor control circuitry is provided so that upon initial withdrawal of film unit portions, information supplied to the circuitry by the film carried indicia will operate the motor only if the processing parameters of the film unit are suitable to those of the camera back.
