<p>PURPOSE:To prevent a duplex paper feeding, by floating the upper papers on a paper feeding tray with an air jet stream from the first air nozzle group, and separating the uppermost paper with an air jet stream from the second nozzle group fed through an air jet collision wall. CONSTITUTION:Upperside papers of the papers 11 loaded on a paper feeding tray 10 are floated up by the air from the first nozzle group 19. Between the uppermost paper and the next upper paper of the floated papers, is blown in the air from the second air nozzle group 20 through an air jet collision wall 21. Thus, the uppermost paper and the next upper paper are separated, and only the uppermost paper is carried in the direction B by a carrier belt 2. Therefore, a duplex paper feeding can be prevented.</p> |
