ABSTRACT:
The vertical stack of trays in a movable tray sorter for sheets of paper enlarge the spacing between consecutive pairs of the trays to accept consecutive sheets of paper by moving the trays along a pair of helical coils, each of which has a turn of relatively coarse pitch. The turns of relatively coarse pitch are located at the copier paper chute and causes an increased separation of adjacent trays only at that position as the coils are turned. The coils support the trays approximately midway between the ends of the trays in a sheet feeding direction and the sorter has vertically extended guides at opposite sides of the trays adjacent one end in which side portions of said trays slide to maintain the trays substantially parallel.
