| description | Apparatus that supports and aligns a pair of glass image masters facilitates relative movements of the masters between separated positions to accommodate insertion of a circuit board, and proximate position in precision alignment of the images carried thereby on opposite sides of the circuit board. Various configurations of reference blocks and engaging followers mounted on one and the other masters assure precision alignment of the masters in proximate position, and resilient bias force exerted in relative orientation between the masters assures precision aligning engagement of followers and reference blocks. Precision positional alignment of one image master relative to the other image master is accomplished by a differential threaded assembly between relatively moveable members interposed between an image master and a follower that engages a reference block. |
