ABSTRACT:
Film boxes for attachment to and use with a camera are keyed and secured by thumb screws to a shutter housing of the camera to permit detachment and accurte reattachment. Light restrictive devices negate transmission of light into each film box upon removal of same. A longitudinally displaceable film reel drive permits rapid disengagement and reengagment of the film boxes without careful alignment and a belt drive prevents, through slippage, film tearing forces.
