An apparatus for moving a document towards the bottom of a document track as the document is moved in first and second directions within the track. The apparatus includes a feed unit positioned on one side of the document track and a cooperating unit positioned on the opposed side of the track. The cooperating unit has a rod which is pivotally supported in a support. A high friction roller is secured to the top end of the rod and a low friction roller is rotatably supported on the lower end of the rod. The feed unit has an idler roller positioned opposite to the high friction roller and also has a drive roller positioned opposite to the low friction roller in the cooperating unit. As the document is moved in a first direction in the document track, the high friction roller causes the rod to pivot slightly, thereby causing the low friction roller on the bottom of the rod to cant slightly, producing a downward component of force on the document as it is moved in the first direction. When the document is moved in the opposite direction, the low friction roller is canted slightly in the opposite direction to produce a downward component of force on the document as it is moved in the second direction.
