Description

Einrichtung zur gleichzeitigen Wiedergabe optischer und akustischer Ereignisse. Bei dem den Gegenstand des Hauptpatents 35o95o bildenden Verfahren zur gleichzeitigen Wiedergabe optischer und akustischer Vorgänge kann bei Verwendung nur eines Filmbandes die Voreilung des Tonfilmes in einfacher Weise dadurch erzielt werden, daß die Tonaufzeichnungen nicht direkt neben den zugehörigen Bildern., sondern vor diesen erfolgen. Bei der Wiedergabe hat dann der Tonstreifen, ununterbrochene und! im Zeitmaß gleichmäßige Aufnahme vorausgesetzt, immer gleiche Voreilung.Device for simultaneous visual and acoustic reproduction Events. In the process forming the subject of the main patent 35o95o for simultaneous reproduction of optical and acoustic processes can be used when using the lead of the sound film achieved in a simple manner by only one film tape that the sound recordings are not directly next to the associated images., but take place in front of these. During playback, the sound strip then has, uninterrupted and! Assuming a uniform recording in terms of time, always the same advance.

Aus insbesondere konstruktiven Gründen kann es vorteilhaft sein, die Voreilung des Tonstreifens auf diese Weise durchzuführen, da dann Bildproj ektionsstelle und Tonwiedergabestelle nicht unmittelbar nebeneinander, sondern räumlich hintereinander auf dem für beide Vorgänge gemeinsamen, Filmband liegen, so daß die voneinander verschiedenen Apparaturen für Bild- und Tonwiedergabe räumlich unabhängig und konstruktiv leicht übersichtlich und zugänglich ausführbar sind.For structural reasons in particular, it can be advantageous to use the Carry out advance of the sound strip in this way, since then Bildproj ektionsstelle and sound reproduction point not directly next to one another, but spatially one behind the other on the film tape common to both processes, so that the one another different devices for picture and sound reproduction spatially independent and constructive can be carried out easily, clearly and in an accessible manner.

Um auch bei Verwendung eines gewöhnlichen .genrein,samen'Filmbandes für Bild und Ton die Voreilung des letzteren unabhängig von der Aufzeichnung bei der Wiedergabe verändern zu können, wird erfindungsgemäß die Einrichtung derart getroffen, daß die Tonlichtquelle gegenüber der Tonschrift räumlich verstellbar angeordnet wird, so daß die Belichtungsstelle des Tonbades bei ablaufendem Film geändert werden kann. Diese Änderung und damit der Wechsel der Voreilung kann beispielsweise selbsttätig bewirkt werden, wie im Hauptpatent angegeben, läßt sich aber nach Bedarf auch von Hand ausführen, indem die Beleuchtungsquelle mit der zugehörigen Apparatur in der Ebene des Filmbandes zwecks Vergrößerung der Voreilung in; Richtung des abrollenden Bandes, zwecks Verkleinerung .der Voreilung entgegengesetzt verschoben wird.In order to avoid even when using an ordinary 'genre-pure, seed' film tape for picture and sound the advance of the latter regardless of the recording To be able to change the reproduction, the device is according to the invention in such a way taken that the sound light source is spatially adjustable with respect to the sound writing is arranged so that the exposure point of the clay bath when the film is running can be changed. This change and thus the change in the lead can, for example be effected automatically, as stated in the main patent, but can be as required also perform by hand by using the lighting source with the associated apparatus in the plane of the film strip for the purpose of increasing the lead in; Direction of the unwinding Band, for the purpose of reducing .the lead is shifted in the opposite direction.
