PAPER FEEDING DEVICE FOR PRINTING MACHINE, AND PRINTING MACHINE HAVING THE SAME

摘要

PURPOSE: A paper feeding device for a printing machine, and a printing machine having the same are provided to make paper enter a paper feeding path in each mode by one feeding roller, thereby simplifying a structure of a printing machine and reducing the manufacturing costs. CONSTITUTION: A returning bracket(110) includes a main returning path(111) connected with a paper feeding path, and a plurality of auxiliary returning paths(112-115) branched from the main returning path. A first feeding roller(120) is rotatively installed at a branched position of the main returning path and the plurality of auxiliary returning paths. The first feeding roller has the size sufficient for covering the plurality of auxiliary returning paths to make paper enter the main returning path. A second feeding roller(130) is rotatively installed in the middle of the main returning path for controlling or arranging a position of paper passing the main returning path.
