ABSTRACT:
A document feed roller and registering rollers are driven through first and second one-way clutches so that the feed roller connected to the motor through the first one-way clutch is driven to forward a document to be processed only when the motor rotates in a positive direction, and the registering rollers connected to the motor through the second one-way clutch are driven to perform skew-correction and forward the document only when the motor rotates in a negative direction. The document is transported for a first part of a document feeding passage by the feed roller and for a second part of the passage by the registering rollers with efficiency merely by switching the rotational direction of the motor.
