ABSTRACT:
The present invention relates to an ejecting roller assembly for use in an automatic document feeder to adaptively adjust the nip force between the follower roller and the driving roller in response to input and output of the paper sheet, there effectively preventing the paper sheet from getting jammed. The ejecting roller assembly includes a swing lever, a follower roller, a friction-generating element and a driving roller. The swing lever is coupled to the follower roller for adaptively adjusting the nip force. The friction-generating element is arranged between the swing lever and the follower roller for facilitating increasing the friction force between the swing lever and the follower roller. The driving roller is used for controlling input and output of the paper sheet.
