ABSTRACT:
A retractable registration apparatus aligns a printing screen with an image platform. The apparatus has a pair of arms. Each arm extends along a longitudinal axis and has at least two sections with a substantially square cross-section along the longitudinal axis and at least two other sections along the longitudinal axis having a circular cross-section inscribed within the square cross-section. A pair of mounting brackets are associated with each of the arms and each have a substantially square opening extending through the bracket for slideably receiving the substantially square cross-section of the arm. The pair of mounting brackets are mounted to the lower surface of an image platform so that the side walls of each bracket are in the same plane and are parallel to the center line. Each arm has a track formed within the arm, and one of the mounting brackets associated with the arm has a guide pin projecting into the arm for guiding the movement of the arm. The track has portions with a longitudinal component for movement of the arm in a translational movement and has portions having a radial component for rotation of the arm about the axis. A finger extends from the arm and has at least one registration pin for registration with the screen frame. The apparatus has a detent for retaining the arms and the registration pins in the retracted position and a second detent for retaining in the exact registration position the arms and the registration pins for aligning the screen frame.
