Description

Wie bekannt, wird zur Zeit bei den Vorführungen von Musikfilmen, um die Gleichmäßigkeit zwischen Film und Musik herbeizuführen, der Film selbst als Spi'elhilfe benutzt, indem der mitphotographierte Kapellmeister ('Beck-Film) oder ein wandernder Notenstreifen (Noto-Fälm) auf der Leinewand erscheint, um so dem Orchesterleiter das "mit dem FilmbMe übereinstimmendeAs is known, is currently in the demonstrations of music films to bring about the equality between film and music, the film itself as a play aid used by the Kapellmeister who was also photographed ('Beck-Film) or a wandering Sheet music (Noto-Fälm) appears on the linen wall, so the orchestra leader the "consistent with the FilmbMe

ίο Musiktempo anzuzeigen. Diese auch vom Zuschauerraum zu beobachtende Spielhilfe ist ein großer Nachteil der bisher gezeigten . Musikfilme, zumal die sichtbare Spielhilfe die Handlungen sehr störend beeinflußt. Bei der Projektion von rückwärts auf einen durchscheinenden Schirm hat man das Bild der Spielhilfe dem Zuschauer schon durch Wände, Vorhänge o. dgl. entzogen.
Im folgenden ist nun eine Vorrichtung be-ίο display music tempo. This play aid, which can also be observed from the auditorium, is a major disadvantage of the one shown so far. Music films, especially since the visible game aid has a very disruptive effect on the actions. When projecting from backwards onto a translucent screen, the image of the play aid has already been withdrawn from the viewer through walls, curtains or the like.
In the following a device is now

ao schrieben, die es ermöglicht, diese Spielhilfe für den Orchesterleiter auch bei Projektion von vorn für das· Auge des Zuschauers unsichtbar zu machen, und zwar geschieht dies gemäß der Erfindung durch einen am unteren Rande des Bildschirmes angebrachten as Spiegel, der auf einen besonderen, nur dem Orchesterleiter und den Musikern sichtbaren Hilfsschirm das kinematographische Bild der Spielhilfen wirft.ao, which makes it possible to use this playing aid for the orchestra leader even when projecting invisible from the front to the eye of the spectator to make, and this is done according to the invention by one at the bottom Edge of the screen attached as a mirror, which is on a special, only that The orchestra conductor and the musicians can see the cinematographic image of the auxiliary screen Game aids throws.

An zwei Ständern a, deren Entfernung voneinander der Breite der Projektionsleinewand k bzw. 4er Spielhilfe entspricht, ruht in den vertikal verstellbaren Lagern b ein drehbarer Spiegel c. In den vertikal sowie horizontal verstellbaren Lagern d befindet sich ein zweiter, breiterer, drehbarer Spiegel e. In den in vertikaler Richtung verstellbaren Lagern/ ruht eine parallel zur Projektionsleinewand stehende weiße Fläche g, die gegen die Ansicht durch einen Schirm h abgeblendet ist und nur durch die öffnung» betrachtet werden kann.A rotatable mirror c rests in the vertically adjustable bearings b on two stands a whose distance from one another corresponds to the width of the projection canvas k or 4-way play aid. In the vertically and horizontally adjustable bearings d there is a second, wider, rotatable mirror e. In the bearings / adjustable in the vertical direction rests a white surface g which is parallel to the projection screen wall and which is shielded from the view by a screen h and can only be viewed through the opening ».

würden angenommen die Lichtstrahlen von m bis » die üblichen, am unteren Rande des Bildes sichtbaren Spielhilfen ausmachen. Die vorher beschriebene Vorrichtung ist so gegen den unteren Rand der Projektionsfläche gestellt, daß die Lichtstrahlen von m bis η auf den unter einem bestimmten Winkel stehenden Spiegele fallen. Dieser Spiegele reflektiert die aufgefangenen Lichtstrahlen auf denthe light rays from m to »would make up the usual play aids visible at the bottom of the picture. The device described above is placed against the lower edge of the projection surface in such a way that the light rays from m to η fall on the mirror at a certain angle. This mirror reflects the captured light rays onto the

ίο Spiegel e. Mit diesem nach allen Richtungen hin verstellbaren Spiegel e ist es möglich, die so aufgefangenen Lichtstrahlen auf die weiße Fläche g zu werfen, und es erscheint somit die durch den Spiegel c aufgefangene, gegenίο mirror e. With this mirror e, which is adjustable in all directions, it is possible to cast the light rays captured in this way onto the white surface g , and the light rays captured by the mirror c thus appear against it

Da diese Fläche nach allen Richtungen hin durch den Schirm ft abgeblendet ist, ist es jetzt nur noch dem Orchesterleiter möglich, diese für ihn ja so wichtige Spiel- ao hilfe durch die öffnung* zu beobachten.the auditorium but covered play aid in the desired depth on the white surface g. Since this area is screened in all directions by the screen ft, it is now only possible for the orchestra conductor to observe this play aid, which is so important to him, through the opening *.
