Abstract: An idler wheel assembly having an idler wheel arm and an idler wheel rotatably mounted on one end of the arm to co-act with a feed wheel located on one side of a document track when the arm is moved from an inactive to an active position relative to the feed wheel. The arm has a pivot area which is mounted to move along the line which is perpendicular to the document track; this enables the assembly to accommodate documents of varying thicknesses. One embodiment uses a loosely mounted pivot point to effect the movement of the pivot area, and a second embodiment uses an elongated slot in the frame of the assembly to effect the movement of the pivot area along the line mentioned.

Abstract: A quick-release mechanism which enables a pinch roller to be moved quickly from its active position with its associated driving roller to a retracted position to enable an operator to remove a jammed document from the area of a document track where the jam occurs.
