Description

Kassette mit zwei Magnetbandspulen Bei magnetischen Aufzeichnungs- und Wiedergabegeräten mit Bändern, bei denen Kassetten für die beiden Bandspulen benutzt werden, muß dafür gesorgt werden, daß die zentralen Löcher in den Spulentellerscheiben stets, d. h. auch bei abgenommener Kassette, den gleichen Abstand voneinander behalten, den sie bei aufgelegter Kassette haben. Dies ist darum schwer zu ermöglichen, weil aus den später erläuterten Gründen eine Bremsung der Tellerscheiben erfolgen muß, wenn die Kassette von den. Antriebszapfen abgenommen wird. Diese Bremsung hat bei den bisher bekannten Einrichtungen eine seitliche Verschiebung der Spulenteller aus ihrer Arbeitslage zur Folge gehabt.Cassette with two magnetic tape reels For magnetic recording and tape players using cartridges for the two tape reels care must be taken to ensure that the central holes in the reel platters always, d. H. keep the same distance from each other even with the cassette removed, that you have when the cassette is in place. This is difficult to achieve because for the reasons explained later, the disk washers must be braked, if the cartridge is from the. Drive pin is removed. This braking has at the previously known devices a lateral displacement of the reel plate resulting from their work situation.

Erfindungsgemäß wird eine wesentliche Verschiebung der Spulenteller bei Abnahme der Kassette von den Zapfen durch nach unten reichende koaxiale Ansätze der Spulenteller und entsprechende Öffnungen der Kassette vermieden.According to the invention, there is a substantial shift in the reel disc when removing the cassette from the pin by downwardly reaching coaxial lugs the spool plate and corresponding openings in the cassette avoided.

In Fig. 1 ist ein Querschnitt durch die Kassette im Arbeitszustand, d. h. aufgesetzt auf die Antriebszapfen 8, gezeichnet. Um bei Abnahme der Kassette von den Antriebszapfen 8 eine Beibehaltung der Lage der Spulenteller 1 zu gewährleisten, erhält der Spulenteller nach unten einen zentrierenden Ansatz, z. B. einen zylindrischen oder leicht konischen Rohrstutzen 12, der in eine entsprechende Ausgestaltung 11 der Kassette lose hineinpaßt. Wird die Kassette abgehoben (Fig. 2), so werden die Spulenteller in die dafür vorgesehenen Öffnungen der Kassette tiefer hineingesetzt und dadurch in ihrer zentralen Lage gehalten. Da nunmehr nur noch notwendig bleibt, die Spulenteller an einer Verdrehung zu hindern, genügen ganz leichte und einfache Bremseinrichtungen, die eine wesentliche Verschiebung der Spulenteller aus der zentrierten Lage nicht zur Folge haben.In Fig. 1 is a cross section through the cassette in the working state, d. H. placed on the drive pin 8, drawn. To when removing the cassette to ensure that the position of the reel disc 1 is maintained by the drive pin 8, receives the reel plate down a centering approach, z. B. a cylindrical or slightly conical pipe socket 12, which in a corresponding embodiment 11 the cassette fits loosely. If the cassette is lifted off (Fig. 2), the The reel plate is set deeper in the openings provided in the cassette and thus kept in their central position. Since now all that remains is To prevent the spool plates from twisting, very easy and simple ones are sufficient Braking devices that cause a substantial shift of the reel disc from the centered Location does not result.

Diese Zentrierung ist baulich einfacher als eine bekannte, bei der von oben wirkende aufwendige Zentrier- und Sperrmittel vorgesehen sind.This centering is structurally simpler than a known one in which Complex centering and locking means acting from above are provided.
