ABSTRACT:
A camera comprises a cassette-receiving chamber for holding a film cassette provided with a light lock which is to be completely closed before removing the cassette from the chamber, closing apparatus movable to completely close the light lock, and a tear away strip for opening the camera to permit the cassette to be removed the chamber. The tear away strip has a pull tab which can be manually grasped to be moved to begin to open the camera. The closing apparatus has a shield at least partially covering the pull tab to prevent the pull tab from being manually grasped to be moved to begin to open the camera, but is moved to uncover the pull tab sufficiently to permit it to be manually grasped to be moved to begin to open the camera when the closing apparatus is moved to completely close the light lock.
