PURPOSE:To achieve accurate feeding by supporting a paper receiving table through parallel arms and moving paper up and down while maintaining parallelness at anytime thereby maintaining the position where a semicircular paper feed roll will contact with the upper face of paper constant. CONSTITUTION:A paper receiving table 13 is supported through parallel arms 14, 14' fixed through fulcrums 4 provided with equi-interval to the sideboard 12 of tray 11 and the paper receiving table 13 to perform rhomboidal link operation through two arms 14, 14', sideboard 12 and paper receiving table 13. Through parallel motion of paper receiving table 13 while employing the sideboard 12 of tray 11 as a fixed member, the contacting position of the upper face of paper and a semicircular paper feed roll 8 when moving up and down on the paper receiving table 13 through a spring 5 is maintained constant thus to maintain the length of paper to be fed through paper feed roll 8 constant. |
