Abstract
A paper feeder is able to properly separate and convey the uppermost sheet of paper from sheets stacked beneath it in a paper bin while effectively preventing multiple paper sheet feeds and other paper feed problems. The paper feeder includes a paper separator for lifting upper sheets, and separating the uppermost sheet from the sheet immediately beneath it by blowing air against an upper-forward end of a stack of paper loaded in a paper bin, and a vacuum paper carrier for holding the uppermost sheet by suction and carrying it. The paper separator has lifting nozzles for lifting side ends of the upper sheets, by blowing air toward side portions, excluding a central portion, of the stack of paper loaded in the paper bin.
