Abstract

As shown in Figures 1 and 2, the sorting apparatus includes a plurality of trays in which tray 56 is one exemplary tray. A lead screw 60 is mounted in frame 58 and connected to motor 62. Frame 59 has a groove 64 for receiving tab 85 of tray 56 therein. A V-shaped yoke 66 extends downwardly from tray 56 and has a follower 68 extending horizontally therefrom Follower 68 is adapted to mesh with the threads of lead screw 60. Tray 56 is inclined and slopes downwardly toward lead screw 60. Frame 59 has a groove 65 on the side opposed to groove 64 for receiving tab 84 therein. Tray 56 has a generally planar surface which is inclined downwardly toward lead screw 60 so as to facilitate the holding of sheets therein. Motor 62 is a bi-directional motor and rotates in the direction of arrow 70 or 72 depending upon the desired direction of the movement of tray 56, i.e., upwardly or downwardly. As shown in Figure 2, lead screw 60 has a low pitch spiral camming surface 74 for positioning the trays closely adjacent to one another, i.e. nesting the trays. An intermediate pitch spiral camming surface 76 is provided to space adjacent trays apart from one another in the sheet entry region. A high pitch spiral camming surface is provided to space adjacent trays apart in a sheet securing region. This enable a portion of a stapler to be positioned between adjacent trays for securing the sets of sheets on the trays passing therethrough to one another. A medium pitch camming surface 80 is provided to space adjacent trays apart from one another a distance sufficient to enable the portion of the stapler to be located therebetween during the stapling operation. Low pitch spiral camming surfaces 74 are located on opposed sides of intermediate pitch spiral camming surface 76 and medium pitch spiral camming surface 80. High pitch spiral camming surface 78 is immediately adjacent intermediate spiral camming surface 76. Medium pitch spiral camming surface 80 is located immediately adjacent high pitch spiral camming surface 78 as well.
