摘要:
A paper feeder comprises a controllably drivable resilient body in frictional contact with a feed roller. A preliminary feeder is provided for supplying a sheet of paper towards an area of the frictional contact from a stack of paper. The roller is driven in a first sense of rotation to feed the supplied paper away from the preliminary feeder. The resilient body is usually driven in a second sense towards the preliminary feeder at the frictional contact area and selectively set free on feeding a thin or flexible sheet. The resilient body may further be driven in the first sense on feeding either a thin or flexible sheet or a ground sheet on which another sheet of paper is attached.
