To explain the invention in more detail, a Exemplary embodiment described in more detail with reference to the drawing

In Fig. 1 is a side view in section and in Fig. 2 is a perspective view of a cassette according to the invention. Two containers 1, 2 for holding a film 3 are connected by a guide part 4 which contains two transparent panes 5, 6. There is a slot in the disk 5 7 is provided through which a drive wheel 8 protrudes into the space between the disks 5, 6. The drive wheel 8 is mounted in one of the side walls 9 or 10 so that it is a safe drive «Wipe the panes 5, 6 pushed film 3 allows. The drive wheel 8 can be provided with before jumps that are in the Perforation of the film 3 intervene. In a tried and tested embodiment, the drive wheel 8 is compliant Friction layer 11 is provided, which the film 3 when the drive wheel 8 rotates. The bearing of the drive wheel 8 is so designed so that in the rest position it is pressed against the disk 6 · the drive wheel 18 continues in the direction of the disk 6 can be pushed, so that by deformation of the friction layer 11 41 · contact surface on the disk 6 is enlarged. the Cassette is made up of two parts, in / dea «in container part 2

forms a closed part except for a slot 12, Which!" can be connected to the component by latching o.a. rtt., which consists of the other container part 1 »the guide part 4, the side walls 9» 10 and the drive wheel 8 »the last mentioned Component v / e also has a tray 13 for receiving the film 3. Xn the containers 1, 2 »and lateral guides 14,15 attached for the film 3, which automatically roll up or unroll the moving film 3. To avoid that the film 3 with his sensitive layer is scratched during movement Lateral spacer bars 16 are arranged between the disks 5, 6, which, to facilitate the insertion of the film, auis the slot 13 protrude

The use of the cassette thus far described is as follows explained · The film 3 is pushed so far into the slot 13, until it reaches the area of the drive wheel 8. By rotation of the wheel 8, the film is transported into the container 1, where it is rolled up as a result of the action of the guides 14 * 15. There the drive wheel 8 protrudes beyond the cassette walls the film 3 is automatically rolled up when the cassette is rolled along a surface · Should the film 3 are rolled too far so that its end lies outside the area of the drive wheel 8, the contact surface of this drive wheel 8 can be enlarged by pressing »After attaching of the separate container part 2, the film can be transported back and forth between the two container parts 1, 2 by the drive wheel

The panes S, 6 of the Ruhiimgäfeei.löä 4 can be designed in such a way that the cassette can be inserted into a correspondingly designed projection device. In this case, an actuator is expediently provided in the projection device, which acts on the drive wheel 8. To protect the films 3 of the film circumferential foils can be arranged in the guide part 4 on each side, which move with d "tm FiZsm and thus prevent a relative movement of the film to other Kassetttenteilen · (t ~ fy>'

The side walls 9, 10 are designed in such a way that when several cassettes are stacked one side wall 9 engages in a side wall 10 of the adjacent cassette. By Vereprtinge at the same time an improved grip for sticking Cuü _e gives the contents of the film ©. · £ concern "

The cassette can also be used in conjunction with projection devices that take up the film strip 3 themselves «: Here the containers 1, 2 are separated and the film in between is in the projection device inserted
