ABSTRACT:
A sheet feeding device has suction cups carried by a linkage which is driven by a drive motor to sequentially press the suction cups onto a paper sheet, transfer the sheet held by the suction cups to another location, and release the sheet from the suction cups. The drive motor is connected to the linkage through a firction gearing mechanism which, through frictional slippage, prevents the suction cups from exerting excessive pressure on the sheets.
