ABSTRACT:
Three registration pins align a mask or other superimposed image with a film strip in both the lateral and longitudinal axes. A compactly constructed shutter and support apparatus permits placement of the shutter in close proximity with a film strip to minimize weight and moment of inertia of the shutter to permit rapid repetitive starting and stopping of the shutter in response to control signals to a drive mechanism. Film boxes are keyed to and secured by thumb screws to the shutter housing to permit detachment and accurate reattachment; light restrictive devices negate transmission of light into each film box upon removal. A longitudinally displaceable film reel drive permits rapid disengagement and reengagement of the film boxes without careful alignment and a belt drive prevents, through slippage, film tearing forces.
