Description
Bei einer Rollfilmkamera findet sich der Vorschlag, die für sich abschließbare Rückwand abklappbar einzurichten, um eine Mattscheibe einschieben zu können, die dann für Einzelaufnahmen etwa auf Platten durch die Kassette ausgewechselt wird; also nicht in der Kamera verbleibt. Weiterhin gibt es Rollfilmkameras, bei denen Einzelbilder durch Einschieben von Kassetten von oben aufgenommen werden können, wobei die Kassette jeweils dieAndrückplatte zurückdrückt. Solche Kameras arbeiten ohne Mattscheibe. Ferner ist eine Kamera bekannt, bei welcher der Mattscheibenrahmen entgegen Federwirkung beim Einführen der Kassette verdrängt wird. Er ist zu diesem Zweck mittels Federn an dem Rückteil angebracht und tritt beim Einschieben der Einzelbildkassette durch ,eine von außen zugängliche Schlitzöffnung zurück.In the case of a roll film camera, there is the suggestion that it is lockable To set up a foldable rear wall in order to be able to insert a ground glass is then exchanged for individual recordings, for example on plates, through the cassette; so does not remain in the camera. There are also roll film cameras where Single images can be recorded by inserting cassettes from above, the cassette pushing back the pressure plate at a time. Such cameras work without a screen. Furthermore, a camera is known in which the focusing screen frame is displaced against the spring action when inserting the cassette. He is to this Purpose attached to the back by means of springs and occurs when the frame is inserted through, an externally accessible slot opening back.
Demgegenüber besteht die Erfindung darin, daß das für Rollfilmkameras bestimmte Rückteil mit gemeinsam nur seitlich wirksamen Führungsschienen für den Mattscheibenrahmen und die Einzelbildkassette ausgestattet ist und daß die Kassettenlage nach dem Blendrahmnen hin nur durch den als Andrückplatte wirksamen Mattscheibenrahmen festgelegt ist. Die Mattscheibe ist somit sowohl als Andrückplatte für den Rollfilm wie ,auch für die Kassette wirksam.In contrast, the invention consists in that for roll film cameras certain back part with jointly only laterally effective guide rails for the Ground glass frame and the single image cassette is equipped and that the cassette position after the window frame only through the ground glass frame, which acts as a pressure plate is fixed. The ground glass is thus both a pressure plate for the roll film like, also effective for the cassette.
Wie aus Abb. i ersichtlich ist, besitzt das Kamerarückteil i den Deckel 2 und die zur Abhaltung des Seitenlichtes aufspringenden Seitenwände 3. An einer Seite befindet sich in der Vertiefung 4 der Schlitz 5 zum Einführen der Kassette. Zwei Schienen 6 an der Innenseite des Rückteils dienen der Kassette als Führung. In dem Ausschnitt 7 und von den Schienen 6 geführt befindet sich der Rahmen 8, in dem die Mattscheibe 9 liegt, die in einem Blechrahmen io befestigt ist. Zwei an der Rückwand befestigte B:attfedern drückenden Mattscheibenrahmen gegen den Blendrahmen. der Kamera..As can be seen from Fig. I, the camera back part i has the cover 2 and the side walls springing open to keep the sidelight 3. On one Side is in the recess 4 of the slot 5 for inserting the cassette. Two rails 6 on the inside of the rear part serve as guides for the cassette. In the cutout 7 and guided by the rails 6 is the frame 8, in which is the ground glass 9, which is fixed in a sheet metal frame io. Two on the rear wall attached to the spring-loaded ground glass frame against the frame. the camera..
Die in Abb. 2 bis 4 dargestellte Kassette besteht aus dem eigentlichen Gehäuse 12 und dem dieses umgreifenden Schieber 13, wie besonders aus Abb.4 in der zusammengeschobenen Lage ersichtlich ist. Der Schichtträger wird in dem Kassettengehäuse 12 von umgebogenen Rändern gehalten. Der Schieber 13 und auch das Gehäuse 12 besitzen Ansätze zum leichteren Zusammenfügen. Der Ansatz am Gehäuse 12 dient auch .als Anschlag und verhindert gleichzeitig das Herausfallen der Kassette in eingeschobener Lage.The cassette shown in Fig. 2 to 4 consists of the actual cassette Housing 12 and this encompassing slide 13, as particularly shown in Figure 4 in the pushed together position can be seen. The substrate is in the cassette case 12 held by bent edges. The slide 13 and also the housing 12 have Approaches to easier assembly. The approach on the housing 12 also serves as a stop and at the same time prevents the cassette from falling out in the pushed-in position.
