filmpatrone with an integrated, lichtblockierenden and spuleblockierenden part

摘要

In a film cassette (1), a light blocking device (57) is supported for movement to a light blocking position for preventing ambient light from entering a cassette shell (3) and to a non-blocking position, and a separate cassette element such as a film spool (5) is supported for movement to use the film cassette. According to the invention, locking means (61) for normally engaging the cassette element (5) to prevent movement of the cassette element is coupled with the light blocking device (57) for movement, when the light blocking means is moved to its non-blocking position, to a non-locking position disengaged from the cassette element to allow movement of the cassette element. Thus, the film cassette (1) cannot be used unless the light blocking device (57) is in its non-blocking position. IMAGE
