Abstract: A sheet justifier provides a table having at least one rotational surface thereon that is substantially aligned with the table. A sheet is input to the table into contact with the rotational surface. A weighted ball is positioned over the rotating surface proximate an outer edge of the rotating surface. The sheet is grasped between the ball and the rotating surface and forced against a raised guide edge. Once the sheet is forced against the guide edge, all rotational driving force is translated in a downstream direction therealong so that the sheet is driven out of the guide edge with its edge aligned therewith in a justified orientation.

Abstract: An automatic fixturing system for printed circuit board testing including a magazine for temporarily storing probes, and a test head adapted to receive selected ones of the probes and position the probes in a pattern matching test points on the printed circuit board. The test head is supported adjacent to the magazine so that selected ones of the probes may be transferred. A base member is positioned adjacent the test head on one side thereof in a position to contact the base of each probe, and the printed circuit board is supported adjacent the test head with the head of each probe adapted to contact a test point on the printed circuit board. The test head includes a probe plate and a base plate positioned in parallel and separated by a spacing substantially the same as the probe length. Separate injector rods are provided for transferring individual probes to the test head.
