PURPOSE: A paper feeding apparatus for a printing machine is provided to solve a skew problem generated when a paper is picked up by preventing deviation of contact pressure applied between pickup rollers and papers. CONSTITUTION: A paper feeding apparatus for a printing machine includes a paper feeding cassette(10) for stacking a plurality of papers thereon. A driving shaft(21) is rotatively supported on a frame of a printer body. One end of a first link arm(22) is rotatively connected to the driving shaft(21). One end of a second link arm(25) is rotatively connected to the other end of the first link arm(22). A pickup shaft(24) is installed at the other end of the second link arm(25). The pickup shaft(24) is rotated by a power applied thereto from the driving shaft(21). A pair of pickup roller(26) are coupled to both ends of the pickup shaft(24) in order to pick up papers.
