Description
Bei Magnettongeräten -mit Magnettonträgern" welche als Folie ausgebildet sind, vor allem bei Bandspielern, hat sich die Schwierigkeit ergeben, daß durch Flattern des Bandes bzw. anders geformter. Magnettonträger vor den Magnetköpfen Störmadulätionen auftreten.In the case of magnetic sound devices - with magnetic sound carriers "which are designed as a film are, especially with tape players, the difficulty has arisen that through Flapping of the belt or other shaped. Magnetic sound carrier in front of the magnetic heads Disturbance adulations occur.
Erfindungsgemäß wird dieser Nachteil dadurch vermieden, daß der Magnettonträger in der Nähe des Luftspaltes eines Magnetkopfes einer pneumatischen Druck- oder Saugwirkung ausgesetzt ist, welche ein glattes Anliegen des Tonträgers auf dem Magnetkopf bzw: einer dem Magnetkopf benachbarten@ Führung bewirkt.According to the invention, this disadvantage is avoided in that the magnetic sound carrier near the air gap of a magnetic head of a pneumatic pressure or suction effect which is a smooth application of the sound carrier on the magnetic head or: a guide adjacent to the magnetic head.
Eine besonders zweckmäßige Ausbildung der Einrichtung nach der Erfindung besteht darin, daß der Magnetkopf bzw. sein Gehäuse selbst längs der Gleitfläche :des Magnettonträgers mit Öffnungen versehen ist und Mittel vorgesehen sind, welche in diesen Öffnungen eine pneumatische Saugwirkung hervorrufen.A particularly useful embodiment of the device according to the invention consists in that the magnetic head or its housing itself along the sliding surface : the magnetic sound carrier is provided with openings and means are provided which create a pneumatic suction effect in these openings.
In der Zeichnung -ist eine Ausführungsform der Einrichtung nach der Erfindung beispielsweise dargestellt.In the drawing -is an embodiment of the device according to the Invention shown for example.
U sind die Pole eines Magnetkopfes, der zum Aufsprechen; Wiedergeben oder Löschen dient. Erfindungsgemäß ist die Polanordnung des Magnetkopfes von einem mit Öffnungen L versehenen, im übrigen aber luftdichten Gehäuse G umgeben. Ein Pumpstutzen P führt vorn Gehäuse G zu einer Luftpumpe. Es sind Mittel vorgesehen, welche bewirken; daß sich die Pumpe automatisch dann einschaltet,- sobald das Bandlaufwerk in Tätigkeit tritt und/oder :der Magnetkopf elektrisch eingeschaltet wird.U are the poles of a magnetic head that is used for recording; Play back or delete. According to the invention, the pole arrangement of the magnetic head is one Enclosed with openings L, but otherwise airtight housing G. A pump nozzle P leads in front of housing G to an air pump. Means are provided which effect; that the pump turns on automatically - as soon as the tape drive is in operation occurs and / or: the magnetic head is switched on electrically.
Die Wirkungsweise der Einrichtung besteht darin, daß das. Magnettonband B durch Saug-Wirkung an die Öffnungen L und damit an die Führungsunterlage F des Magnetkopfgehäuses angepreßt wird, wodurch jegliches Flattern des Bandes vermieden wird.The mode of operation of the device is that the magnetic tape B by suction to the openings L and thus to the guide pad F des Magnetic head housing is pressed, thereby avoiding any flutter of the tape will.
Die Erfindung ist nicht auf das Ausführungsbeispiel beschränkt. Unter Umständen können die Pole des Magnetkopfes selbst ganz oder teilweise als Gehäusewände ausgebildet sein und dementsprechend mit Perforationslöchern versehen sein. An die Stelle der Saugwirkung kann auch eine pneumatische Druckwirkung treten, die von Düsen auf das Band ausgeübt wird, welche dem Magnetkopf gegenüber auf der anderen Seite des Bandes angeordnet sind.The invention is not restricted to the exemplary embodiment. Under Under certain circumstances, the poles of the magnetic head themselves can be used in whole or in part as housing walls be designed and accordingly be provided with perforation holes. To the Instead of the suction effect, a pneumatic pressure effect can also occur, which is generated by Nozzles exerted on the tape which face the magnetic head on the other Side of the tape are arranged.
