Description

Drahttongeräte enthalten eine Spule, von der der Draht abgewickelt wird und eine Spule, auf die der Draht nach dem Vorbeiführen an einem Magnetkopf wieder aufgewickelt wird. Solche Geräte sind z. B. als -Diktiermaschinen gebräuchlich. Die Spülen können aber auch in einer auswechselbaren Fassette angeordnet werden, z. B. für ein sogenanntes sprechendes Buch. In diesem Fall ist eine einfache Bedienung erwünscht, weil das Gerät von Laien benutzt wird.Wire tone machines contain a spool from which wire is unwound is and a spool on which the wire after passing a magnetic head is rewound. Such devices are e.g. B. commonly used as dictation machines. The sinks can also be arranged in an exchangeable facade, z. B. for a so-called speaking book. In this case, the operation is simple desirable because the device is used by laypeople.

Erfindungsgemäß enthält das Drahttongerät für diesen Zweck eine Vorrichtung, die beim Aufsetzen der Kassette den Magnetkopf; der mit einer aus zwei gegeneinander geneigten Flächen bestehenden Führungsvorrichtung für den Draht versehen ist, an den. zwischen den beiden Spulen verlaufenden: Draht heranführt und ihn beim Abnehmen der Kassette wieder entfernt. Auf diese Weise wird vermieden, daß ein besonderer Bedienungsgriff bedient werden muß. Da sich nämlich der Draht im Verlauf des Auf- bzw. Abwickelns in verschiedenen Höhenlagen bewegt, muß am Magnetkopf, wie bekannt, eine Führungsvorrichtung angeordnet werden, die den Draht unabhängig von seiner jeweiligen Lage vor den Luftspalt des Magnetkopfes führt. Diese Führungsvorrichtung muß vor dem Aufsetzen bzw. Abnehmen der Kassette zur Seite geschwenkt werden, was bei der Erfindung automatisch geschieht.According to the invention, the wire-tone device contains a device for this purpose, the magnetic head when the cassette is put on; the one with one of two against each other inclined surfaces existing guide device for the wire is provided on the. running between the two coils: bring wire up and take it off removed from the cassette. This way it is avoided that a special Operating handle must be operated. Since the wire moves in the course of the or unwinding moves at different heights, must on the magnetic head, as known, a guide device can be arranged, which the wire independently of its respective position in front of the air gap of the magnetic head. This guiding device must be swiveled to the side before mounting or removing the cassette, what happens automatically in the invention.

Die Abbildung zeigt ein Ausführungsbeispiel der Erfindung in schematischer Darstellung. Die Kassette K enthält zwei Spulen Sp und wird so auf das Drahttongerät aufgelegt, daß die Achse A des Motors Mo (einschließlich Zwischengetriebe) durch die eine Spule hindurchgeführt wird. Bei diesem Auflegen bewegt sich der Stift St nach unten und dreht den zweiarmigen Hebel H entgegen der Kraft der Feder F so, daß der Magnetkopf 111 in das Innere der Kassette hineinbewegt wird und dabei mit seiner Führungsvorrichtung, die aus zwei gegeneinander geneigten Flächen besteht, den Draht auffängt, so daß der Draht an dem Luftspalt anliegt. Um zu vermeiden, daß unter dem Einfluß der Feder F die Kassette K nach oben bewegt wird, empfiehlt sich die Anbringung von Rasten, in die die Kassette einschnappt.The figure shows an embodiment of the invention in a schematic representation. The cassette K contains two spools Sp and is placed on the wire clay device in such a way that the axis A of the motor M o (including the intermediate gear) is passed through the one spool. During this placement, the pin St moves down and rotates the two-armed lever H against the force of the spring F so that the magnetic head 111 is moved into the interior of the cassette and with its guide device, which consists of two mutually inclined surfaces, the Wire catches so that the wire rests against the air gap. In order to avoid that the cassette K is moved upwards under the influence of the spring F, it is advisable to attach notches into which the cassette snaps.

Beim Abheben der Kassette bewegt sich der Magnetkopf M zwangläufig wieder zurück.When the cassette is lifted off, the magnetic head M inevitably moves back again.

PATENTANSPRUCH: Drahttongerät mit einer aufsetzbaren Kassette, die je eine Spule zum Abwickeln und Aufwickeln des Drahtes enthält, zwischen denen ein _ Magnetkopf liegt, dadurch gekennzeichnet, daß es eine Vorrichtung enthält, die beim Aufsetzen der Kassette den Magnetkopf, der mit einer aus zwei gegeneinander geneigten Flächen bestehenden Führungsvorrichtung für den Draht versehen ist, an den zwischen den beiden Spulen verlaufenden Draht heranführt und ihn beim Abnehmen der Kassette wieder entfernt. Angezogene Druckschriften: USA.-Patentschriften 1Nr. 2 513 653, 2 513 617; schweizerische Patentschrift 17r. 262 323. Claim: Wire tone device with an attachable cassette, each containing a spool for unwinding and winding the wire, between which a _ magnetic head is located, characterized in that it contains a device that, when the cassette is placed, the magnetic head, which with one of two against each other inclined surfaces existing guiding device for the wire is provided, leads to the wire running between the two coils and removes it again when the cassette is removed.
