PROBLEM TO BE SOLVED: To provide an ejecting roller assembly for use in an automatic document feeder avoiding paper jam at the ejecting roller assembly by automatically adjusting clamping force by taking-in and taking-out paper. SOLUTION: The ejecting roller assembly for the automatic document feeder mainly comprises a joy stick, an ejecting play block, a friction device, and an driving roller. Of them, the joy stick is used for connecting it to the ejecting play block. The ejecting play block is appropriately used for changing the clamping force. The friction device is installed between the joy stick and the ejecting play block and is used for strengthening friction force between the joy stick and the ejecting play block. The driving roller is used for controlling input and output of the paper. COPYRIGHT: (C)2008,JPO&INPIT
