A paper aligner mechanism is described which offers a compact, low-cost method for positive alignment of paper sheets. The figure shows an aligner 10 consisting of DC motor 11 on whose shaft is disposed a pulley 12 and an actuator arm 13 which rotates freely on the motor shaft through a one-way clutch. On the end of actuator arm 13 is a freely rotating pulley 14 in alignment with pulley 12. Drive belt 15, such as an O-ring, is attached to the pulleys. In operation, when DC motor 11 is activated to turn in a clockwise direction, the one-way clutch (Torrington) locks to the motor shaft and lifts the actuator arm off the paper tray against stop 17 where the motor stalls out and is held in this position as long as current is applied to the motor.
