Abstract
The vertical stack of trays in a movable tray sorter for sheets of paper exiting a copies is moved in a manner to 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.
