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.
Claims10
Apparatus for reversing the direction of movement of cut sheet items continuously moved from an input stack to an output receptacle without interruption or double feed comprising:
- oppositely disposed continuously moving contrarotating means arranged in the path of movement of individual cut sheet items,
- means producing a normal force on one of said contrarotating means for moving an item into said reversing apparatus,
- means producing a normal force on the other of said contrarotating means for moving said item in reverse direction exiting said item from said reversing means,
- signal controlled means coupling both said normal force producing means for reversing item direction in response to an applied signal, and
- one-way means in the entering path of movement of said item effective to prevent backward movement of said item into the entering pathway.
