ABSTRACT:
Orientation of a removable film gate with a docking frame is accomplished by a releasable locator connector assembly in conjunction with a force-responsive clamp assembly. The locator connector assembly includes a male connector subassembly on the removable film gate and a female connector subassembly located on the docking frame. A spring-biased threaded screw in the male connector subassembly connects with a tapped end of a locator pin in the female connector subassembly. The threaded screw and tapped locator pin locate each other by a cone-shaped protrusion at the top of the locator pin in conjunction with a recessed area of a locator seat within the male connector subassembly. The force-responsive clamp assembly accepts a tab of the removable film gate when the film gate is pushed into the photographic film printer, and releases the tab when a pulling force is applied to the film gate. The releasable locator connector assembly prevents movement of the film gate relative to the docking frame along each of an X, Y and Z axes, as well as preventing rotation of the film gate about the X and Y axes. The force-responsive clamp assembly prevents rotation of the film gate about the Z axis.
