Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Stillsetzen von Magnettongeräten bei Trägerbruch.The invention relates to a device for stopping Magnetic devices in the event of a carrier break.

Bei derartigen Vorricht n ist es bekannt, den stromleitenden Träger in eiragenen Stromkreis einzuschalten, so daß bei seinem Bruch eine Stromunterbrechung eintritt. Der Träger biegt zu diesem Zweck einem Kontakt an.In such devices, it is known to use the electrically conductive carrier to be switched on in an electric circuit, so that if it breaks, a power interruption entry. For this purpose, the carrier bends a contact.

Es hat sich nun herausgestellt, daß beim Ablaufen des Trägers ein ununterbrochenes straffes Anliegen des Kontaktes an dem Träger schwer erreichbar ist, so daß sich bei der Wiedergabe durch Mikrofunkenbildung akustische Störungen bemerkbar machen.It has now been found that when the carrier runs off a uninterrupted tight application of the contact to the wearer difficult to achieve so that during playback there is acoustic interference due to microsparks to make noticable.

Dieser Nachteil wird nun bei der Erfindung dadurch vermieden, daß beide Spulen, die aufwickelnde und die abwickelnde,- von den übrigen, den Träger auf seinem Weg berührenden Teilen elektrisch isoliert sind und durch leitende Verbindung miteinander über eine Stromquelle und eine Relaisanordnung, bei sonstiger Körperisolation voneinander, als Stromzuleitung zu dem Träger benutzt werden.This disadvantage is avoided in the invention in that both coils, the winding and the unwinding, - of the rest, the carrier Parts in contact on its way are electrically isolated and by a conductive connection with each other via a power source and a relay arrangement, with other body insulation from each other, can be used as a power supply line to the carrier.

Der Gedanke der Erfindung ist besonders einfach zu verwirklichen, wenn ein Trägerantrieb mit drei Motoren benutzt wird, von denen einer zur Erzielung des Trägergleichlaufs dient.The idea of the invention is particularly easy to implement, if a carrier drive with three motors is used, one of which is used to achieve the carrier synchronization is used.

Eine derartige Ausführungsform ist in der Zeidhming schematisch dargestellt.Such an embodiment is shown schematically in the Zeidhming.

In dieser Zeichnung ist 2 eine Grundplatte, an der von unten Isolierblöcke 3 befestigt sind. Auf diesen Isolierblöcken sitzen die Motoren 4 und 5, die die Spulen 6@und@ 7. antreiben. Zwischen den Spulen 6 und 7 ist der drahtförmige Träger 8 gespannt, der bei 9 den Sprech- und Abhörkopf durchläuft. Die Stromquelle-io bedient einen Stromkreis, der sich über die Relaiseinrichtung i i zur Ausschaltung der Motoren und- Einschaltung der Bremsen, den Motor 5, die Spule 6, den Draht 8, die Spule 7, den Motor 4 schließt. Bricht der Draht 8 oder ist er zu Ende, so wird der Stromkreis unterbrochen und die Relaiseinrichtung i i kommt zur Wirkung.In this drawing, 2 is a base plate to which insulating blocks are attached from below 3 are attached. The motors 4 and 5, which the Drive bobbins 6 @ and @ 7.. The wire-shaped carrier is located between the coils 6 and 7 8 excited, which goes through the speaking and listening head at 9. The power source-io served a circuit that is via the relay device i i to switch off the motors and- engaging the brakes, the motor 5, the coil 6, the wire 8, the coil 7, the motor 4 closes. If wire 8 breaks or if it comes to an end, the circuit becomes interrupted and the relay device i i comes into effect.
