Abstract
A roller module is adapted for use with an automatic document feeder, and is adapted for feeding of a document sheet therethrough. The roller module comprises a first roller, a second roller disposed adjacent to and parallel to the first roller and cooperating with the first roller to define a nip, a driven component co-rotatable with the first roller, and a driving component rotatable for abutting against and driving the driven component to rotate, thereby permitting feeding of the document sheet through the nip. During rotation of the driving component, the document sheet is brought into contact with the first and second rollers for a predetermined time period to perform skew correction before the driving component rotates the driven component.
