"Bandkassette für Magnetophone"."Tape cassette for magnetophones".
Die Neuerung betrifft eine Bandkassette für Magnetophone.The innovation concerns a tape cassette for magnetophones.
In den Bandkassetten bekennten Typs ist zwischen ü^n beiden Gehäuseseiten und den Bandspulen eine Kunststoff-Folie angebracht, die gute Gleitfähigkeiten aufweist.In the tape cassettes known type is between ü ^ n both sides of the housing and attached to the tape reels a plastic film which has good sliding properties.
Jedoch wird diese Folie durch die Reibung der Bandspule während der Aufnahme und Wiedergabe des Bandes elektrisch aufgeladen, so daß di e Spulen vollständig oder fast daran hängen bleiben. Dadurch wird jede Spule blockiert und die Fortsetzung der Aufnahme oder Wiedergabe wird praktisch unmöglich.However, this film is caused by the friction of the tape reel during the Recording and playback of the tape electrically charged, so that the e Bobbins completely or almost caught on them. This will make each The bobbin is blocked and recording or playback is practically impossible.
Gegenstand der vorliegenden Neuerung ist deshalb eine Bandkassette des oben angegebenen Typs, die den Nachteil der Kassetten bekannter Art nicht aufweist. Der Gegenstand der Neuerung ist daher eine Bandkassette für Magnetophone, die dadurch gekennzeichnet ist, daß jede der beiden Seitenwände ihres Gehäuses, zwischen welchen die Bandspulen eingeschlossen sind, innen mit einer Hartmetallfolie ausgekleidet ist.The present innovation is therefore a tape cassette of the type indicated above, which does not suffer from the disadvantage of the cassettes of the known type. The object of the innovation is therefore a tape cassette for magnetophone, which is characterized in that each of the two side walls of its housing, between which the tape reels are enclosed, lined inside with a hard metal foil is.

in der Abbildung der beigefügten Zeichnung wird im Grundriß eine Seitenwand der neuerungsgemäßen Bandkassette dargestellt.in the figure of the attached drawing is a plan view Side wall of the tape cassette according to the invention shown.
Bei Betrachtung dieser Abbildung und unter Berücksichtigung der Tatsache, daß die andere Seite der dargestellten Seite spiegelbildlich ' gleich ist, ist zu sehen, daß die neuerungsgemäße Bandkassette eines Magnetophons auf jeder der beiden Seiten 1 ihres Gehäuses, zwischen welchen die Magnetbandspulen 2 und 3 eingeschlossen sind, innen mit einer Hartmetallfolie 4 ausgekleidet ist.Looking at this figure and taking into account the fact that the other side of the side shown is a mirror image ' is the same, it can be seen that the tape cassette according to the invention of a magnetophone on each of the two sides 1 of its housing, between which the magnetic tape reels 2 and 3 are enclosed inside is lined with a hard metal foil 4.
Jede Folie 4 ist in irgend einer V/eise, z.B. durch Anleimen, an derEach foil 4 is in some way, e.g. by gluing, to the
Vorzugsweise ist die Folie aus Beryllium-Kupfer oder aus rostfreiem Stahl oder aus Phosphorbronze.The foil is preferably made of beryllium copper or of stainless Steel or phosphor bronze.
Die Hartmetallfolien 4, auch wenn sie einen leicht höheren Reibungskoeffizient als die genannten Kunststoff-Folien aufweisen, werden während des Betriebs nicht elektrisch aufgeladen und vermeiden folglich den oben angeführten Nachteil der genannten Kunststoff-Folien. The hard metal foils 4, even if they have a slightly higher coefficient of friction than the plastic films mentioned are not electrically charged during operation and are avoided consequently the above-mentioned disadvantage of the plastic films mentioned.
