发明名称 Method and apparatus for uniformly stacking cut sheets of printed media.
摘要 <p>A method and apparatus for-stacking-cut-sheets-of-printed-media wherein the leading edge of sheets (20) received from a printer or plotter (10) are first passed vertically downward into a bin (40) and then rotated through an angle away from the printer or plotter. The front side member of the bin has a convex, upwardly facing and smoothly contoured section (60) thereof over which cut sheets are laid with a uniform weight distribution and then down into an adjacent sheet output collection tray (62). This method of sheet transport and stacking has the advantage of minimizing the crumpling and curling of the cut sheets during the sheet handling and accumulation process. In addition, this method rapidly and efficiently moves the cut sheets out of the way of upstream sheet feeding to thereby prevents paper jam and crushing of paper in the plotter or printer. The apparatus for carrying out this method is of economical and durable construction and may be readily retrofitted to existing large size plotters for handling and stacking relatively large size cut sheets of printed media. <IMAGE></p>
