Patent ID: 7628401

Claim:
An ejecting roller assembly for use in an automatic document feeder to transport a paper sheet, said ejecting roller assembly comprising: a swing lever having a first end coupled to said automatic document feeder such that said swing lever is pivotal about said first end; a follower roller coupled to a second end of said swing lever; a resilient element arranged between said swing lever and said follower roller for facilitating increasing the friction force between said swing lever and said follower roller; and a driving roller coupled to said automatic document feeder, wherein said follower roller applies a downward component of force to said driving roller when said paper sheet is transported therebetween in an inward direction due to a downward rotational response of said swing lever, such that the nip force between said follower roller and said driving roller is increased, and said follower roller applies less force to said driving roller when said paper sheet is transported therebetween in an outward direction due to a upward rotational response of said swing lever, such that the nip force between said follower roller and said driving roller is reduced.
