Description
Die Erfindung bezieht sich auf eine weitere Ausbildung der Vorrichtung zum Festklemmen einer in den von den beiden Spulenenden eines Tonkopfes für Magnettongeräte gebildeten Spalt eingelegten Folie nach Patent 872 658.The invention relates to a further embodiment of the device for clamping one of the two coil ends of a sound head for magnetic recorders formed gap inserted film according to patent 872 658.
Nach dem Patent 872 658 kennzeichnet sich diese Vorrichtung durch eine einen nach innen gerichteten Druck auf die Magnetschenkel ausübende Klammer, deren Ebene nach dem Ausführungsbeispiel. des Hauptpatentes senkrecht auf der Tonkopfebene steht.According to the patent 872 658, this device is characterized by a clamp that exerts an inward pressure on the magnet legs, their level according to the embodiment. of the main patent perpendicular to the head plane stands.
Diese Vorrichtung wird nun gemäß der Erfindung dadurch verbessert, daß, als Klammer ein gabelförmiges urimagnetisches, verhältnismäßig dickes Blech in. der Tonkopfebene Verwendung findet, dessen Schenkelköpfegleichzeitigzur Schallspeicherführung dienen.This device is now improved according to the invention by that, as a bracket, a fork-shaped urimagnetic, relatively thick sheet metal in. the sound head plane is used, whose thigh heads at the same time for the sound storage guide to serve.
Es. ist bekannt; zur Schonung der Tonkopfmagneten und des Schallspeichers am Tonkopf besonders harte Auflagen, z. B. aus Achat, zu verwenden.It. is known; to protect the tape head magnets and the sound storage particularly hard pads on the tape head, e.g. B. agate to use.
Demgegenüber wird gemäß der Erfindung der Klammerwerkstoff, der vorzugsweise Lagermetalleigenschaften hat, als Führung benutzt. Es hat sich gezeigt, daß dieser weiche Werkstoff einem insbesondere drahtförmigen Schallspeicher eine Schmierung gibt, durch die er unter Vermeidung von Abnutzung an den Tonkopfspalten vorbeigleiten kann.In contrast, according to the invention, the clip material, which is preferably Has bearing metal properties, used as a guide. It has been shown that this soft material a particular wire-shaped sound storage a lubrication through which it glides past the gaps in the sound head while avoiding wear and tear can.
Die Klammer gemäß der Erfindung gibt zugleich eine Betturig für den Tonkopf, mit der zusammen er in seinem Gehäuse eingelegt, vorzugsweise eingeklemmt werden kann.The clip according to the invention is also a Betturig for the Sound head, with which it is inserted into its housing, preferably clamped can be.
Die Zeichnung zeigt beispielsweise schematisch eine Ausführungsform der Erfindung im Aufblick. In dieser Zeichnung ist 2 der Tonkopf mit den Spalten. 3 und 4 und den Schenkeln $, 6 und 7, an deren Kopf der Schallspeicher r r vorbeigleitet. Anschließend an die Schenkelköpfe 5 und 7 finden sich die Schenkelköpfe 8 und 9 der Klammer io, welche die Schenkels und 7 nach innen drücken und dadurch in die Spalte 3 und 4 eingelegte Folien festklemmen. Bevor der Schallspeicher an den Spalten 3 und 4 vorbeigleitet, liegt er den verhältnismäßig breiten Schenkelköpfen 8 bzw. 9 auf und erhält dadurch eine Art Schmierung.The drawing shows, for example, schematically an embodiment of the invention at a glance. In this drawing, 2 is the tape head with the columns. 3 and 4 and the legs $, 6 and 7, at the head of which the sound storage r r slides past. Subsequent to the leg heads 5 and 7 are the leg heads 8 and 9 of the clamp io, which press the legs and 7 inwards and thereby into the Clamp the inserted foils in columns 3 and 4. Before the sound storage at the columns 3 and 4 slides past, it lies on the relatively wide leg heads 8 and 9 and thereby receives a kind of lubrication.
