<p>PURPOSE:To reduce a sorter for a copying machine or the like to a compact size by oscillating a plurality of trays at small pitch portions of a feed screw member and quickly oscillating a tray passing a sorting position at large pitch portions. CONSTITUTION:When a screw rod 8 is rotated forward by a motor 22, upper and lower nuts 9, 10 formed in small pitch are moved upward so that each tray 4 is moved upward through a lower spring 14. When a tongue piece 18 of an assigned tray 4''' is fitted in a spiral groove 17 of a guide nut 11, the tray is quickly moved in a large pitch to enlarge an interval with a low tray 41 at a position corresponding to a sorting position P, so that paper B is smoothly stored in the tray without jamming. In this arrangement, even if the interval between the trays is narrowed to reduce the sorter to a compact size, a paper jam can be prevented.</p> |
