ABSTRACT:
A reversing mechanism for use with a cut sheet item feeder in a printer/copier wherein a pair of contrarotating roller members each of which is angularly oriented relative to the horizontal rotative axes thereof operate in conjunction with individual spring biased pressure rollers solenoid actuated so as to cause sheet items disposed therebetween to move selectively in either one of two opposite directions and wherein a one-way movable member disposed in the path of the items prevents the items from returning back into the input pathway. Photo optical control means actuated by passage of each item time the reversal mode of the apparatus by applying a reversal signal to the solenoid actuating device controlling the contrarotating rollers.
