摘要 |
The invention relates to a film cassette for a photosensitive film consisting of a light-proof, flat flexible case substantially equal in length to the strip of film and a cassette opening which extends perpendicularly of the length of the case and which is provided with light-sealing means whereby the top part and the bottom part of the cassette being fixedly interconnected solely in the vicinity of the cassette opening and the other three edges are displaceable relative to one another in light proof labyrinths, even if the case is bent, the strip of film retains its freedom of movement.
