ABSTRACT:
A sheet alignment device for lining up a sheet being fed to a proper location for printing operation is disclosed. A driving gear is fittingly inserted and mounted on an axial end portion of a pivot on which at least a pair of feeding rollers are integrally formed. A torsion coil knock-up spring is used to link the pivot and the driving gear. When operated, the torsion coil knock-up spring reserves and accumulates torsion moment of the pivot. Upon cease of rotational motion of driving gear, the accumulates torsion moment forces the pivot to continue rotation thereof, allowing a sheet to advance more thereby securing printing operation from failure.
