Abstract: A slide track, pin registration system for registering photosensitive media to light exposure equipment. The system includes one or more slide tracks and each of which contain media registration pins. The slide tracks are orthogonally mounted within grooves let into a resilient media support mat. Each pin is restrained in a spring biased retainer which retainer is loosely confined in a support base that slide mounts to the track. The number of pins and profile shapes are variable to match the media and registration requirements. In one vacuum system, the tracks are supported in a multi-chambered, foam backed bladder. In another the tracks are supported on a single chambered bladder. In still another system, the retainer slides within grooves formed in a rigid board.

Abstract: An imaging support assembly for precise and repeatable alignment and registration of plural, planar workpieces having a plurality of projecting registration pin assemblies. The workpieces contain holes where projecting pins of the registration pin assemblies are received. At least one of the registration pin assemblies contains a projecting pin of a non-circular shape when viewed end-on. A flanged barrel of the assembly is rigidly mounted to a planar support board. The projecting pin is spring biased within a sleeve that mounts in the barrel. The pin projects through a barrel aperture and is non-rotatively movable in the plane of the board within limits defined by the barrel aperture.
