Description
Kinematographischer Aufnahmeapparat mit optischem Ausgleich Die Erfindung bezieht sich auf einen kinematographischen Aufnahmeapparat mit optischem Ausgleich der Bildwanderung durch eine rotierende Spiegeltrommel. Bei solchen Apparaten erfolgte bisher die Anordnung der Filmrollen oder der Filmbandkassette außerhalb der Spiegeltrommel, wodurch naturgemäß die Ausmaße solcher Apparate besonders große Dimensionen annahmen.Cinematographic recording apparatus with optical compensation The invention refers to a cinematographic recording device with optical compensation the image wandering through a rotating mirror drum. With such apparatus took place previously the arrangement of the film rolls or the film tape cassette outside the mirror drum, whereby the dimensions of such apparatus naturally assumed particularly large dimensions.
Dieser Übelstand wird nach der Erfindung dadurch vermieden, daß der Hohlraum der Innenspiegeltrommel zur Aufnahme der Kassette für den Film dient. Durch diese Maßnahme wird ein besonders kleiner und handlicher Aufnahmeapparat mit optischem Ausgleich erzielt, der bei nicht allzu großem Filmfassungsvermögen leicht und bequem mitgeführt werden kann. Bei Vorführungsapparaten mit optischem Ausgleich ist es bekannt, innerhalb der Ausgleichstrommel die Filmspulen anzuordnen.This drawback is avoided according to the invention in that the The cavity of the inside mirror drum is used to hold the cassette for the film. By this measure is a particularly small and handy recording device with optical Achieved balance that is easy and convenient if the film capacity is not too large can be carried. In the case of demonstration equipment with optical compensation, it is known to arrange the film reels within the compensation drum.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in Abb. r im Aufriß und in Abb. a im Grundriß dargestellt; a ist die von einem Gehäuse b umgebene rotierende Spiegeltrommel, bei der in bekannter Weise die einzelnen 'Spiegel im Innern der Trommel angeordnet sind. In dem Hohlraum der Spiegeltrommel sind erfindungsgemäß die Filmrollen c und d bzw. die Filmkassette e untergebracht. Die zur Fortbewegung des Filmbandes dienende Apparatur befindet sich ebenfalls in dem Hohlraum der Spiegeltrommel. Der Antrieb der Filmrolle c sowie der Vor- und Nachwickelrollen f und g und der Filmtransportrolle 1a erfolgt durch einen in der Spiegeltrommel angebrachten Zahnkranz i mit Innenverzahnung, von dem aus durch Zahnradübertragung die Fortbewegung der einzelnen Elemente erfolgt.In the drawing, an exemplary embodiment of the subject matter of the invention is shown in elevation in Fig. R and in plan view in Fig. A; a is the rotating mirror drum surrounded by a housing b , in which the individual 'mirrors are arranged in the interior of the drum in a known manner. According to the invention, the film rolls c and d or the film cassette e are accommodated in the cavity of the mirror drum. The apparatus used to move the film tape is also located in the cavity of the mirror drum. The drive of the film roll c as well as the pre- and post-winding rollers f and g and the film transport roller 1a is carried out by a ring gear i with internal teeth which is attached to the mirror drum and from which the individual elements are moved by gear transmission.
