Stencil printer with controlled movement of paper rack and ink drum

Abstract

A stencil printer includes a hollow cylindrical, porous ink drum freely rotatable. A multistage paper feeding device includes a plurality of paper stacking portions and capable of feeding papers of particular size from each paper stacking portion. At least one pair of side fences are mounted on each paper stocking portion for positioning the papers in the widthwise direction of the papers. A rack is positioned to stack the papers or printings each carrying a printed image thereon. An ink drum shifting device shifts the ink drum in the widthwise direction of the papers perpendicular to the direction of conveyance of the papers. A rack shifting device shifts the rack in the widthwise direction of the papers. A storing device stores the position of a center line of a paper transport path for each of the paper stocking portions. A control section controls the operation of the ink drum shifting device and that of the rack shifting device in accordance with the position of the center line stored in the storing device.
