Description
Es ist bekannt, die den Film an die Transportrolle andrückenden Organe schwenkbar und gefedert auszubilden. . .It is known that the organs pressing the film against the transport roller can be pivoted and to train sprung. . .
TJm das Volumen kinematographischer Aufnahmeapparate auf das äußerste zubeschränken, ist entgegen den bisher bekannten Anordnungen der Andrückorgane, welche ein Abklappen von der Filmtransportrolle nur innerhalb des von den Wänden des Apparategehäuses eingeschlossenen Raumes gestatten, die Anordnung der Andrückorgane erfindungsgemäß so getroffen, daß ein Abschwenken derselben auch über das Apparategehäuse hinaus ermöglicht wird. Dieser Anordnung liegt ein Aufnahmeapparat zugrunde, bei dem die Filmtransportrollen aus dem Apparategehäuse herausragen. Um die Filmandrückorgane über die Gehäusewände hinausschwenken zu können, sind dieselben einseitig ausgebildet, so daß sie nur auf den äußeren Zahnkranz der Transportrollen drücken. Dies genügt, um dem Film eine gute Führung zu geben. Durch die vorbeschriebene Anordnung der Filmandrückorgane wird ein freier Raum zwischen Filmtransportrolle und Gehäusewand geschaffen, welcher ein leichtes Einlegen des Filmbandes in den Apparat ermöglicht. TJm to limit the volume of cinematographic recording apparatus to the utmost, is contrary to the previously known arrangements of the pressure elements, which fold down from the film transport roll only within the from the walls of the apparatus housing allow enclosed space, the arrangement of the pressing members according to the invention made so that it can be swiveled away even beyond the apparatus housing will. This arrangement is based on a recording device in which the film transport rollers protrude from the device housing. In order to be able to swivel the film pressure elements over the housing walls, the same are formed on one side, so that they only apply to the outer ring gear of the transport rollers to press. This is enough to give the film a good guide. The above-described arrangement of the film pressure elements is a free space created between the film transport roller and the housing wall, which is a light Insertion of the film tape in the apparatus allows.
In der Zeichnung ist in einem Ausführungsbeispiel in Abb. 1 in Seitenansicht, Abb. 2 in Draufsicht und Abb. 3 im Grundriß die Anordnung und Ausbildung des Filmandrückorganes dargestellt. Der Andrückschuh 1 ist in einer Buchse 2 drehbar gelagert und wird durch eine Feder 3, welche auf eine mit der Lagerbuchse des Andrückschuhes verbundene Nocke 4 drückt, dauernd gegen die Transportrolle 5 gepreßt. Im abgeschwenkten Zustand des Andrückschuhes 1 legt sich die Feder 3 auf die andere Seite der Nocke 4 und hält den Andrückschuh in seiner aufgeklappten Lage fest. Ein Stift 6 dient dem Andrückschuh ι in der Arbeitsstellung als Anschlag, In the drawing, in an exemplary embodiment in Fig. 1 in side view, Fig. 2 in Plan view and Fig. 3 in plan the arrangement and design of the film pressing member shown. The pressure shoe 1 is rotatably mounted in a socket 2 and is by a Spring 3, which presses on a cam 4 connected to the bearing bushing of the pressure shoe, pressed continuously against the transport roller 5. In the pivoted-away state of the pressure shoe 1 the spring 3 lies on the other side of the cam 4 and holds the pressure shoe in his opened position firmly. A pin 6 serves as a stop for the pressure shoe ι in the working position,
