Abstract: A sorting apparatus for differentiating between generally identically shaped objects based upon code indicia provided on a predetermined, relatively small surface area portion on the sidewall of each object, including: a transfer assembly for moving the objects in single file relationship along a transfer path; a spinning assembly for engaging an object in the transfer path and for spinning the engaged object about its longitudinal axis during a relatively short duration spinning period without removing the object from the transfer path; a trigger assembly for sensing the passage of a trigger indicia, located at a predetermined circumferential position on the surface of the object relative to the code indicia; a code indicia reading assembly for reading the code indicia printed on the object; a reading actuation assembly responsive to the trigger signal for actuating the code indicia reading assembly at a time when the code indicia on the object is positioned in indexed, readable relationship with the reading
