| abstract |
This invention relates to a sorting apparatus for receiving sheets from a copying machine. A plurality of tray members receive the sheets as the tray members move past a sheet discharge zone. The drive rotates cam members to move the tray members vertically as sheets are moved along the sheet path towards the tray members. The cam members are formed with variable pitch camming surfaces such that the tray members are in close proximity to each other except when positioned adjacent to the sheet discharge zone, whereupon the camming surfaces affect a spreading movement of the trays upon passing the sheet discharge zone. |
