Description

Einrichtung zur Herstellung von Bildtonfilmen Die Erfindung bezieht sich auf eine Einrichtung zur Herstellung von Bildtonfilmen, bei denen neben der Bildreihe eine Tonaufzeichnung vorhanden ist, die aus mehreren nebeneinanderliegenden übereinstimmenden Zackentonspuren besteht.Apparatus for Making Picture Sound Films The invention relates to on a device for the production of picture sound films, in which in addition to the A series of images is a sound recording made up of several adjacent matching jagged tone traces exists.

Es ist bekannt, derartige Zackentonspuren dadurch herzustellen, daß man eine Vielzackenblende oder deren Bild gegenüber einem Spalt bewegt, der auf dem Film abgebildet wird. Es ist bei dieser Anordnung schwierig, die Blende herzustellen, insbesondere dann, wenn es sich um eine-grö ßere Zahl von Zacken handelt. Weiterhin ist es auch schwierig, die einzelnen Zacken genau übereinstimmend zu machen, um übereinstimmende Tonspuren zu bekommen.It is known to produce such jagged sound tracks that a multi-pointed aperture or its image is moved across from a gap that opens the film. With this arrangement it is difficult to manufacture the diaphragm, especially when it is a question of a larger number of spikes. Farther it is also difficult to make the individual prongs exactly match to get matching audio tracks.

Diese Schwierigkeiten werden gemäß der Erfindung dadurch beseitigt, daß unmittelbar vor dem Film eine der Anzahl der Aufzeichnungen entsprechende Anzahl von Linsen, vorzugsweise Zylinderlinsen, angeordnet sind, welche die Blendenöffnung der Projektionsoptik auf dem Film abbilden.According to the invention, these difficulties are eliminated by that immediately before the film a number corresponding to the number of recordings of lenses, preferably cylindrical lenses, are arranged, which the aperture the projection optics on the film.

Die Erfindung wird an Hand der Fig. i und 2 beispielsweise erläutert.The invention is explained with reference to FIGS. I and 2, for example.

In Fig. i sind unmittelbar vor dem Film i mit der Emulsion 2 drei Linsen 3, die vorteilhaft als ZylinderlinsEn ausgebildet sein können, angeordnet, von denen jede die Öffnung der Blende 4 auf den Film photographiert. Dabei ist zwischen der ruhenden Lichtquelle und den Zylinderlinsen eine Optik angeordnet, die die Lichtquelle auf dem Film abbildet. Die Blende 4 ist im oder am Aufnahmeobjektiv angeordnet, von dem ein Teil durch die Linse 5 dargestellt ist. Die Steuerung des zur Belichtung dienenden Lichtstrahles kann durch einen Oszillographenspiegel erfolgen, der die Zackenschrift erzeugt; hierbei ist es vorteilhaft, die Blende 4 so auszubilden, wie sie in Fig. 2 in Ansicht dargestellt ist. Die Blendenöffnung weist hier die Form eines Dreiecks auf, auf das ein Lichtspalt 6 von einem Oszillographenspiegel geworfen wird.In Fig. I, immediately before film i with emulsion 2, there are three Lenses 3, which can advantageously be designed as cylindrical lenses, are arranged, each of which photographs the opening of the diaphragm 4 on the film. It is between the stationary light source and the cylindrical lenses an optics arranged, which the light source depicted on the film. The diaphragm 4 is arranged in or on the taking lens, part of which is represented by lens 5. Control of the exposure serving light beam can be done through an oscilloscope mirror, which the Zigzag generated; here it is advantageous to design the diaphragm 4 in such a way that as shown in Fig. 2 in view. The aperture here shows the Shape of a triangle on which a light gap 6 from an oscilloscope mirror is thrown.
