Description

Anordnung zum Synchronisieren von getrennt betriebenen Ton-und Bildaufzeichnungen für auf einem Filmstreifen befindliche Einzelbilder Die Erfindung betrifft eine Anordnung zum Synchronisieren eines Einzelbilder aufweisenden Filmstreifens mit einem getrennt betriebenen, die Tonaufzeichnungen enthaltenden Magnetband.Arrangement for synchronizing separately operated sound and image recordings for individual images located on a film strip The invention relates to a Arrangement for synchronizing a film strip having individual images with a separately operated magnetic tape containing the sound recordings.

Bekannt sind eine Reihe von Anordnungen, die mechanisch durch beispielsweise Perforation des Magnettonbandes betrieben werden. Die Nachteile sind ein rasches Verschmutzen der Kontakte, so daß die Funktionssicherheit nicht mehr gegeben ist.A number of arrangements are known which are mechanically carried out by, for example Perforation of the magnetic tape are operated. The drawbacks are a quick one Soiling of the contacts, so that the functional reliability is no longer given.

Auch sind Anordnungen bekannt, bei denen durch die Perforation des Magnettonbandes der Schaltvorgang mittels Foto- oder Selenzelle ausgelöst wird. Diese Anordnungen sind wohl betriebssicher, aber auf Grund der dazu notwendigen Bauteile viel zu aufwendig und unwirtschaftlich.Arrangements are also known in which the perforation of the Magnetic tape, the switching process is triggered by photo or selenium cells. These arrangements are safe to operate, but due to the necessary Components far too expensive and uneconomical.

Andere Anordnungen sehen die Kontaktgabe über eine auf das Magnettonband geklebte Kontaktfolie vor, welche im Augenblick des Schaltvorganges einen galvanischen Schalter berührt. Auch hier ist erfahrungsgemäß infolge häufiger Verschmutzung die Funktionssicherheit nicht gewährleistet.Other arrangements see the making of contact via a on the magnetic tape glued contact foil, which at the moment of the switching process a galvanic Switch touched. Here, too, experience has shown that, due to frequent contamination, the Functional reliability not guaranteed.

Durch die Erfindung werden diese Mängel dadurch beseitigt, daß die Steuerung zum Gleichlauf der Ton-und Bildaufzeichnungen durch kapazitive Einwirkung auf einen Oszillatorkreis bewirkt wird, den das mit metallischer Auflage versehene Magnettonband durchläuft. Zweckmäßig kann dieses zugleich als Dielektrikum wirken.The invention overcomes these deficiencies in that the Control for the synchronization of the sound and image recordings through capacitive action is effected on an oscillator circuit, which is provided with a metallic coating Magnetic tape goes through. This can expediently act as a dielectric at the same time.

Die Erfindung wird an Hand eines Ausführungsbeispielen erläutert.The invention is explained using an exemplary embodiment.

Das Magnettonband 1 (Abb. 1), welches stellenweise mit einer metallischen Auflage 2 versehen ist, wird über ein Kondensatorenplattenpaar 3, 4 geführt, das unter kapazitiver Einwirkung eines Oszillatorkreises 6 steht. Die während der Zeit des Durchlaufes gebildete Kreiskapazität des Oszillatorkreises 6 (Abb. 2) wird zum Schwingen angeregt, und die hierdurch auftretende Änderung des Anodenstromes setzt ein Relais 7 in Funktion, wodurch das Kontaktpaar 8 betätigt wird und dieses die Steuerautomatik in Tätigkeit setzt.The magnetic tape 1 (Fig. 1), which in places with a metallic Edition 2 is provided, is passed over a capacitor plate pair 3, 4, the is under the capacitive action of an oscillator circuit 6. The during the time of the cycle formed circular capacity of the oscillator circuit 6 (Fig. 2) is to Vibrations are excited, and the resulting change in the anode current sets a relay 7 in function, whereby the contact pair 8 is actuated and this the Automatic control puts into action.

Die erfindungsgemäße Anordnung bietet größte Funktionssicherheit, da eine Verschmutzung der kapazitiven Kontakte ohne Einfluß auf den Schaltvorgang ist.The arrangement according to the invention offers the greatest functional reliability, as contamination of the capacitive contacts has no effect on the switching process is.
