Abstract:
A method of moving a document to be transported to a scan region of a document scanning device from a document stack comprising the steps of:a) picking a single sheet of document from a surface of a stack of sheets of documents by contacting opposite face sides of said sheet with opposed moveable members which apply differing amounts of frictional force to opposite face sides of said sheet;b) rotating a first one of said moveable members with a first torque to apply a first frictional force to the surface of said sheet facing outwardly of said stack; andc) rotating a second one of said moveable members with a second torque to apply a second frictional force to the surface of said sheet which faces said stack, said first torque and force being higher than said second torque and force.
