Abstract of the Disclosure Apparatus for locating and pressing circuit printed boards to be tested in a printed circuit board testing apparatus onto an array of test contacts positioned in accordance with the test points on the printed circuit board. The circuit boards to be tested are supported in a plane parallel with the test contact plane and for movement from an initial position to a test position. Positioning means are provided for properly aligning the circuit board to be tested with the test contacts. The circuit board supporting means is mounted for pivoting into a circuit board placement position turned away from the test contact plane. The positioning means comprises at least one light marker projector mounted to optically position a correspondingly marked circuit board to be tested on the up-turned support. Pneumatic, mechanical and/or electromechanical means are provided for fixing the printed circuit board in its aligned position on the circuit board supporting means. Page
