    Abstract: A multibin, cut-sheet xerographic copier capable of operating in a simplex or a duplex copy mode, wherein sheets are fed from a selected sheet stack one at a time, to the copier's transfer station, by a sheet feeding means which includes a combing wheel. The combing wheel shingles the leading edge of the stack's top sheet to an open feed roller nip, to be sensed there by a pneumatic sensor. Sensing of this leading edge causes the combing wheel to be lifted off the stack. Subsequently, at a time determined by the crpier's control logic, the drive nip closes to thereby feed the top sheet to the copier's paper registration gate, and then to its transfer station. As soon as this sheet's trailing edge has cleared the pneumatic sensor, and the drive nip has opened, the next sheet is staged at the shingled position, in the open drive nip. Side-one copied sheets, of intended duplex copies, are automatically stacked in a duplex bin. The bottom of the duplex bin includes a flat, resilient bottom-of-the-bin pad. This pad's position is adjustable in a plane parallel to the bottom of the duplex bin, to facilitate control of the direction in which sideone copied sheets are fed out to the copier's paper registration gate, for side-two copying.

    Abstract: A multibin, cut-sheet xerographic copier capable of operating in a simplex or a duplex copy mode, wherein sheets are fed from a selected sheet stack, one at a time, to the copier's transfer station, by a sheet feeding means which includes a coming wheel. The combing wheel shingles the leading edge of the stack's top sheet to an open feed roller nip, to be sensed thereat by a pneumatic sensor. Sensing of this leading edge causes the combing wheel to be lifted off the stack. Subsequently, at a time determined by the copier's control logic, the drive nip closes to thereby feed the top sheet to the copier's paper registration gate, and then to its transfer station. As soon as this sheet's trailing edge has cleared the pneumatic sensor, and the drive nip has opened, the next sheet is staged at the shingled position, in the open drive nip.

    Abstract: An improved apparatus for successively separating and feeding sheets from a stack of sheets is disclosed. A wave generator wheel, rotating in a plane generally parallel to the stack, and about a tiltable axis generally perpendicular to the stack, is tiltable in a first direction to contact the stack for shingling the stack, and in a second direction to the contact the stack for restoring the stack to its unshingled state. Sheets in a stack are driven forward or rearward by simply tilting the rotating wheel. The wave generator wheel is controlled by an open-loop or closed-loop control arrangement to first drive the stack's top sheet away from a feed nip, and to then drive the stack's top sheet into the feed nip. Instead of tilting the wheel, the wheel can be in the form of rollers connected to a disk via flexible spokes which are depressed to contact and drive the stack's top sheet.

    Abstract: A multibin, cut-sheet xerographic copier capable of operating in a simplex or a duplex mode, wherein sheets are fed from a selected sheet stack, one at a time, to the copier's transfer station, by a sheet feeding structure which includes a resilient combing wheel. The combing wheel is of a unique resilient construction, such that it exhibits a spring rate and damping factor which minimizes acoustical noise and enhances reliable, repeatable shingling of the top sheet of a stack to a closable sheet drive nip.
