Description

Einrichtung zum Geben von Signalen bei der Neuaufzeichnung der vorhandenen Tonspur eines Bildtonfilmstreifens Es ist bereits bekannt, bei der Neuaufzeichnung der vorhandenen Tonspur eines Bildtonfilmstreifens Signale zu geben, die als Leit- und Anzeigemittel dienen.Device for giving signals when new recording of the existing ones Soundtrack of an image sound filmstrip It is already known when re-recording to give signals to the existing soundtrack of an image sound film strip, which serve as a guiding and display means are used.

Es ist weiterhin bereits bekannt, Filmstreifen, insbesondere auch Bildtonfilmstreifen, mit Marken geeigneter Art für die Steuerung von Signaleinrichtungen der verschiedensten Art zu versehen.It is also already known to use film strips, in particular Picture sound film strips, with marks of a suitable type for the control of signaling devices of various kinds to be provided.

Bei Bildtonfilmstreifen können diese Marken entweder außerhalb der Breite der Tonspur, etwa zwischen den Perforierungen und den Rändern, oder aber innerhalb der Tonspur angeordnet werden. Im zuletzt genannten Falle muß jedoch, wenn die ursprüngliche Tonspur bei der Neuaufzeichnung, etwa zu Vergleichs- oder aber zu Kontrollzwecken, zu Gehör bringbar sein soll, zum mindesten ein für eine brauchbare Wiedergabe tauglicher Teil derselben erhalten bleiben. Das heißt also, Signalmarken und restliche Tonspur müssen nebeneinander in der Breite einer normalen Tonspur liegen.In the case of image sound film strips, these marks can either be outside of the Width of the sound track, for example between the perforations and the edges, or else be arranged within the soundtrack. In the latter case, however, if the original soundtrack when re-recording, for example for comparison or but for control purposes, it should be able to be heard, at least one for one usable reproduction suitable part of the same are preserved. So that means, Signal marks and the rest of the soundtrack must be next to each other in the width of a normal Soundtrack.

Die Erfindung bezieht sich nun auf eine Einrichtung zum Geben von Signalen bei Neuaufzeichnung der vorhandenen Tonspur eines Bildtonfilmstreifens, auf dem die Signalsteuermarken und die Tonspur innerhalb der Breite einer normalen Tonspur nebeneinanderliegen, um dort abgetastet zu werden. Die Erfindung selbst besteht darin, daß das zu dem Projektor gehörige Lichttongerät Wahl- und wechselweise als solches und als Kontaktgebegerät für die Steuervorrichtung einer Signaleinrichtung verwendet wird, indem es, j e nach Erfordernis, um mindestens die Breite einer normalen Tonspur parallel zur Ebene des Filmstreifens verschoben oder der aus dem Lichttongerät austretende Lichtstrahl mittels optischer Umlenkmittel in entsprechender Weise abgelenkt wird; Maßnahmen, die an sich bekannt sind.The invention now relates to a device for giving Signals when re-recording the existing soundtrack of an image sound filmstrip, on which the signal control marks and the sound track within the width of a normal Audio tracks lie next to each other in order to be scanned there. The invention itself consists in the fact that the light sound device belonging to the projector is optional and alternating as such and as a contact device for the control device of a signaling device is used by adding it, as required, to at least the width of a normal Sound track shifted parallel to the plane of the film strip or that from the light sound device exiting light beam deflected in a corresponding manner by means of optical deflection means will; Measures that are known per se.

Diese Ausnutzung der an sich bekannten Mittel, das Lichttongerät zwecks Wechsels der Abtastlinie parallel zur Ebene des Filmstreifens zu verschieben oder aber den aus dem Lichttongerät austretenden Abtaststrahl mittels optischer Umlenkmittel auf eine andere Abtastlinie einzustellen, macht es möglich, den bei der Neuaufzeichnung der vorhandenen Tonspur oft erforderlichen schnellen Wechsel zwischen Tonwiedergabe und Signalgabe in besonders einfacher Weise vorzunehmen, und zwar, was von ganz besonderem Vorteil ist, unter gleichzeitiger Verwendung des Lichttongerätes als Kontaktgebe-gerät. Die Einrichtung gemäß der Erfindung erspart somit nicht allein ein besonderes Zusatzgerät zum Projektor, sondern ermöglicht auch ein besonders einfaches und sehr schnelles Arbeiten. Hinzu kommt, daß sich die erforderlichen Steuermarken in einem Streifen der Tonspur besonders leicht anbringen und der vorhandenen Tonspur mit Hinblick auf die neu aufzunehmende sehr einfach zuordnen lassen. Außerdem sind die Marken im Bereich der Tonspurbreite weinger gefährdet als etwa auf den äußersten r. Rändern.This use of the means known per se, the purpose of the light sound device Change the scan line parallel to the plane of the filmstrip or move but the scanning beam emerging from the optical sound device by means of optical deflection means setting to a different scan line makes it possible to re-record the existing soundtrack often required quick changes between sound reproduction and signaling to make in a particularly simple manner, and what of quite It is particularly advantageous when the light sound device is used at the same time as Contact device. The device according to the invention therefore does not save alone a special accessory to the projector, but also enables a special easy and very fast work. In addition, the necessary Particularly easy to apply tax stamps in a strip of the soundtrack and the existing ones Soundtrack with Very easy to assign with regard to the new to be included permit. In addition, the brands are less endangered in the area of the audio track width than about the extreme r. Margins.
