Abstract
A film cassette comprises light blocking means supported for rotation to a light blocking position for preventing ambient light from entering the cassette interior and to a non-blocking position. The light blocking means has a cavity configured for permitting a driver element to rotate in the cavity initially without rotating the light blocking means out of its light blocking position and then into driving engagement with the light blocking means to allow the driver element to rotate the light blocking means from its light blocking position to its non-blocking position. A locking pawl protrudes into the cavity to secure the light blocking means in its light blocking position and is adapted to be displaced from the cavity to release the light blocking means when the driver element is rotated initially in the cavity without rotating the light blocking means out of its light blocking position.
