ABSTRACT:
A device for driving documents having one edge in contact with a reference plane includes a drive roller having its axis perpendicular to the reference plane, and an idle roller pressing a drive document against the drive roller. The axis of the idle roller can be freely tilted in a plane parallel to the plane of the driven document, between two limit positions on either side of a position perpendicular to the reference plane. A spring urges the idle roller against an abutment at one end of its axis to create friction.
