Patent ID: 8128083

Claim:
Apparatus comprising: a rotatable picking member adapted to pick sheets generally one at a time from a stack of sheets, wherein the picking member includes a disk portion, wherein the disk portion includes an axis, wherein the disk portion is rotatable about the axis, wherein the disk portion includes a high friction arcuate segment, wherein the high friction arcuate segment includes a high friction arcuate surface, wherein the high friction arcuate segment is adapted to act on an end sheet bounding a stack, wherein the disk portion includes an arcuate projecting portion, wherein the arcuate projecting portion includes a projecting surface, wherein along a same circumferential section, the projecting surface is axially adjacent to the high friction arcuate segment in a direction parallel to the axis, wherein the projecting surface extends circumferentially along only a portion of the high friction arcuate surface, wherein the projecting surface is disposed radially outward relative to the axis further than the high friction arcuate segment, wherein the projecting surface is adapted to act on a leading edge area of the end sheet to prevent deformation of the leading edge area as the end sheet is acted upon by the high friction arcuate segment.
