Description

DEUTSCHESGERMAN

Es sind Rollfilmkameras bekannt, bei denen der vorher in eine doppelwandige Rollkassette eingelegte Film mit der lichtverschlossenen Rollkassette eingesetzt und durch Drehen der Rollkassette aufnahmebereit wird.Roll film cameras are known in which the previously inserted into a double-walled roll cassette The film is inserted with the light-sealed roll cassette and ready for exposure by turning the roll cassette will.

Dabei besteht die Rollkassette aus zwei koaxialen Zylindern, deren äußerer beim Drehen der Kassette durch einen Anschlag festgehalten wird. Durch das Drehen allein des inneren Zylinders werden zwei Schlitze in der äußeren und der inneren Schale miteinander in Deckung gebracht und geben dadurch den Austritt in einen Filmkanal frei. Um hierbei das Einführen des Films in den Filmkanal zu erleichtern, ist gemäß der Erfindung der Filmkanal mit einem Verschluß versehen, der beim Drehen der Rollkassette durch einen Anschlag an deren äußerer Wandung geöffnet wird und dabei eine Einlauföffnung in den Filmkanal bildet. Dabei kann der Filmkanalverschluß aus einer festen und einer beweglichen Platte gebildet sein.The roller cassette consists of two coaxial cylinders, the outer one when the cassette is rotated is held by a stop. Just turning the inner cylinder becomes two Slits in the outer and inner shell are brought into line with one another and thereby give the Exit into a film channel free. In order to facilitate the introduction of the film into the film channel According to the invention, the film channel is provided with a closure that when rotating the roll cassette is opened by a stop on the outer wall and thereby an inlet opening in the Film channel forms. The film channel closure can be formed from a fixed and a movable plate be.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in den Zeichnungen dargestellt. Darin ist 1 die Vorratskassette der fotografischen Kamera; 2 ist der lichtempfindliche Film, davon befindet sich ein Stück (etwa 20 mm) außerhalb der Kassette. 3 und 4 sind die zwei koaxialen Kassettenhülsen, die man beim Laden der Kassette voneinander abziehen kann.An exemplary embodiment of the subject matter of the invention is shown in the drawings. In it 1 is the Photographic camera supply cassette; 2 is the photosensitive film, there is a piece of it (about 20 mm) outside the cassette. 3 and 4 are the two coaxial cassette sleeves that you will find in the Loading the cassette can peel from each other.

Schiebt man die geladene Kassette in die fotografische Kamera, dann wird die Hülse 3 durch die Nase 5 festgehalten, wogegen die innere Hülse 4 mit dem Knopf 6 um etwa 90° entgegen dem Uhrzeigersinn gedreht werden kann. Dabei wird die lichtdicht geschlossene Kassette geöffnet, d. h., die beiden Schlitze der koaxial angeordneten Hülsen stehen dann übereinander, so daß der Film frei herausgezogen werden kann. Beim Drehen der Kassette wird gleichzeitig mit der Nase 7 der Filmkanal 8 abgehoben, so daß sich der Film dazwischenlegen kann. Dreht man den Transporthebel 9 in Pfeilrichtung bis zum Anschlag nach außen, dann wird der Film mit Hilfe der Rollfilmkamera mit doppelwandigen
Rollkassetten
If the loaded cassette is pushed into the photographic camera, the sleeve 3 is held in place by the nose 5, whereas the inner sleeve 4 can be rotated counterclockwise by about 90 ° with the knob 6. The light-tight closed cassette is opened, that is, the two slots of the coaxially arranged sleeves are then one above the other, so that the film can be pulled out freely. When the cassette is rotated, the film channel 8 is lifted off at the same time as the nose 7 so that the film can be placed in between. If the transport lever 9 is rotated outwards in the direction of the arrow as far as it will go, the film is then double-walled with the aid of the roll film camera
