Self-adjusting paper decurler.

摘要

Lower, arced decurling guide (1) is pivoted on pin (3) and biased upward by spring (7). Upper stop (11) prevents the lower guide from moving closer to upper decurling roller (15). Paper (9) is guided between these upper and lower guides and the lower guide is moved outward in proportion to the rigidity of the paper being decurled. This automatic adjustment provides good decurling for all papers within a broad range of rigidity.
