Description
Beim Einschneiden einer mechanischen Tonspur in einen Tonschriftträger stört häufig der anfallende Span, der sich vor den Schneidestift legt und dadurch Unregelmäßigkeiten der entstehenden Tonspur ergibt, die sich bei der Wiedergabe als Nebengeräusche und Tonverzerrungen auswirken. Bei Tonaufzeichnungsgeräten für plattenförmige Tonschriftträger hat man daher schon vorgeschlagen, den anfallenden Span auf der Achse des Plattentellers aufzuspulen. Auch bei Aufzeichriungsgeräten für bandförmige Tonschriftträger hat man schon Vorrichtungen vorgesehen, die den entstehenden Span beseitigen, indem dieser mittels Vakuums abgesaugt wird. Eine solche Vorrichtung ist natürlich umständlich und verteuert das Aufnahmegerät sehr. Außerdem stört diese Art der Spanbeseitigung dadurch, daß eine Absauge-When cutting a mechanical sound track into a sound writing medium it is often bothersome the resulting chip that lies in front of the cutting pin and thereby irregularities of the resulting soundtrack, which appears as background noise and sound distortion during playback impact. In the case of sound recording devices for disc-shaped sound text carriers, it has therefore already been proposed that the resulting chip on the axis of the turntable to rewind. Also with recording devices for tape-shaped sound writing carriers devices have already been provided to remove the resulting chip, by sucking it off by means of a vacuum. Such a device is natural cumbersome and makes the recording device very expensive. Also, this kind of bothers you Chip removal by the fact that a suction
ao vorrichtung niemals geräuschlos arbeitet und daher Nebengeräusche erzeugt, die unter Umständen mit aufgezeichnet werden.ao device never works silently and therefore generates background noises that may be recorded with.
Die Erfindung betrifft eine sehr einfache Vorrichtung zur Beseitigung des bei der Aufzeichnung von Tönen auf bandförmigen Tonschriftträgern entstehenden Spanes, die aus einer neben der Aufzeichnungstrommel angebrachten Spule besteht, auf der der Span fortlaufend aufgewickelt wird.The invention relates to a very simple device for eliminating the during recording Chips produced by tones on tape-shaped tone writing carriers, which are attached to a recording drum next to the recording drum There is a coil on which the chip is continuously wound.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung im Schnitt dargestellt.An embodiment of the invention is shown in section in the drawing.
In den über die Aufzeichnungstrommel ι geführten Film ifl wird von der in der Schalldose 2 befindlichen Nadel eine Tonspur eingeschnitten, wobei der Span 3 anfällt. Sobald dieser eine genügende Länge hat, wird er an der Spule 4 befestigt und nun fortlaufend von dieser aufgewickelt. Die Spule wird durch das Kegelradgetriebe 5 unmittelbar von der Aufzeichnungstrommel angetrieben und ist durch den Lagerarm 6 mit der Lagerung 7 der Aufzeichnungstrommel verbunden. Die Lagerachse 7" trägt gleichzeitig die Schwungmasse 8 und erhält durch Riemenübertragung vom Motor 9 ihren Antrieb. A sound track is cut into the film i fl guided over the recording drum ι by the needle located in the sound box 2, the chip 3 being produced. As soon as this has a sufficient length, it is attached to the spool 4 and is now continuously wound up by this. The reel is driven directly from the recording drum by the bevel gear 5 and is connected by the bearing arm 6 to the bearing 7 of the recording drum. The bearing axis 7 ″ at the same time carries the flywheel 8 and receives its drive from the motor 9 by belt transmission.
