Film registration gate assembly

A film registration assembly, for positioning at a positioning location longitudinally successive, uniform rectangular image frames on a strip film bounded between a pair of parallel rows of equidistant, uniform rectangular edge perforations of common cross sectional size, each perforation in one row being transversely aligned with a corresponding perforation in the other row, said assembly comprising:

• a focal positioning location member having a front face and a rear face with the positioning location being complemental to an image frame of the strip film and having longitudinally extending first and second transverse sides and transversely extending third and fourth longitudinal sides, and the front face having film perforation seating, and film frame focal positioning, first and second surfaces correspondingly extending longitudinally along the first and second transverse sides;
• registration means comprising first and second pins of smaller cross sectional size than the film perforations and disposed perpendicular to the surfaces in fixed alignment with a reference line extending transversely from a first point on the first surface to a second point on the second surface, and at a fixed longitudinal location adjacent one longitudinal side of the positioning location, and corresponding to the positioning of a pair of transversely aligned film perforations on the surfaces at the first and second points, the pins being arranged for entry into the perforations;
• and
• force applying means for engaging the film at a position corresponding to at least a third point on the second surface spaced longitudinally from the second point for moving the film under a force in a direction oblique to the reference line, upon entry of the pins into the perforations, to produce a resultant force on the perforation at the first point and on the perforation at the second point for registering precisely a film frame with the aperture by the pins.
