Abstract
The aligner mechanism comprises first and second control sleeves keyed to end portions of a shaft. First and second levers are pivotally mounted on the shaft adjacent to the first and second control sleeves for movement between first and second positions. A pinch roller is rotatably mounted on the levers opposite a drive roller. The aligner mechanism also includes an aligner bar having a first leg portion and a second leg portion secured to the first and second control sleeves respectively, and an engaging portion joining the first and second leg portions. The first lever has a projection cooperating with a control member on the first control sleeve and the second lever has a projection cooperating with a control member on the second control sleeve so as to provide lost motion coupling to pivotally move the first and second levers from a first position to a second position. The aligner bar engages the first wall before the first and second levers are pivotally moved to the second position to introduce a bend in each of the first and second legs causing the engaging portion to be biased against the first wall before the first and second levers rotate to the second position. The projections also cooperate with the control member when a resilient element biases the shaft to the first position to enable the rollers to pinch the document before the engaging portion disengages the first wall.
