Description
Antriebsanordnung bei Magnettongeräten Im Patent 816907 ist eine Antriebsanordnung bei Magnettongeräten beschrieben, die mit bandförmigen Magnetogrammträgern arbeiten, welche beim Betrieb von einer Gummiandruckrolle an die Antriebs-ro#lle gedrückt werden, mit dem Kenn, zeichen, daß die Gummiandruckrolle um eine senkrecht zur Antriebsrollenachse liegende Achse so weit abklappbar angeordnet ist, daß ein leichtes Bandeinlegen ermöglicht wird, wobei gemäß einer zweckmäßigen Weiterbildung durch das Klappern die Schaltvorgänge ausgelöst werden,die das Gerät betriebsbereit machen.Drive arrangement in magnetic recorders In patent 816907 there is a drive arrangement described for magnetic recorders that work with tape-shaped magnetogram carriers, which is pressed against the drive roller by a rubber pressure roller during operation be, with the identifier, sign that the rubber pressure roller around a perpendicular to the drive roller axis lying axis is arranged so that it can be folded down so that the tape can be easily inserted is made possible, according to an expedient development by the rattling the switching processes are triggered that make the device ready for operation.
Bei Magnettongeräten, bei denen wahlweise aufgenommen und wiedergegeben werden kann, besteht bei unsachgemäßer Bedienung die Gefahr, daß bei der Wiedergabe der Aufnahmeschalter betätigt wird und durch den Vormagnetisierungsstromdie Aufzeichnung gelöscht oder zum mindesten in der Amplitude stark herabgesetzt wird. Bei einem Gerät mit einerAntriebsanordnung nach dem Hauptpatent läßt sich dieser Nachteil gemäß der Erfindung dadurch weitgehend vermeiden, daß dem klappbaren Träger für die Gummiandruckrolle eine Sperrvorrichtung für die Sechalterstellung Aufnahme zugeordnet ist"die bewirkt,daß,das Gerät bei jedem Einschalten durch das Anklappen der Andruckrolle an dieTrieb-rolle zunächst als Wiedergabegerät arbeitet und erst eine besondere Schaltmaßnahme getroffen werden muß, um auf den Aufnahinebetrieb übergehen zu können und den Schalter nach dieser Schaltmaßnahme inder Aufnahme-Stellung selbsttätig zu halten. Dadurch wird die Bedienungsperson gezwungen, sich vor dem Umlegendes Schalters zu überlegen, ob sie den Schalter auf Aufnahme umlegen darf, und es ist unmöglich, einfach durch Umklappen der Andruckrolle das Gerät in Aufnahme-Stellung einzuschalten.For magnetic recorders, where you can choose to record and play back there is a risk of improper use during playback the recording switch is actuated and the recording is made by the bias current deleted or at least greatly reduced in amplitude. At a Device with a drive arrangement according to the main patent eliminates this disadvantage according to the invention thereby largely avoid that the foldable carrier for the rubber pressure roller is assigned a locking device for the six-age recording is "which has the effect that the device is switched on by folding in the pressure roller an dieTtrieb roll initially works as a playback device and only a special one Switching action must be taken in order to be able to switch to recording mode and the switch after this Switching action in the recording position to hold automatically. This forces the operator to stand in front of the Throwing the switch to consider whether she may throw the switch to recording, and it is impossible to put the device in the recording position simply by folding down the pressure roller to turn on.
Die Fig. i veranschaulicht ein Ausführungsbeispiel -des Gegenstandes -der Erfindung. An dem Kopfträgergehäuse i,dasden sowohl als Sprech- als auch als Hbrkopf dienenden Magnetkopf 2 und die Antriebsrolle 3 enthält, ist mittels des Scharniers 4 eine Tragvorrichtung 5 für die Gummiandruckrolle 6 angebracht. Diese Tragvorrichtung ist in einem Züistand dargestellt, in dem sie um i8a0' abgeklappt ist. An der Tragvorrichtung 5 ist ein sich nach innen erstreckender Ansatz 7 angebracht, der beim Zuklappen den Stift 8 nach unten bewegt, und zwar gegen die, Wirkung der Feder 9, die sich einerseits gegenden Flansch i o, andererseits gegendas Widerlager i i, durch dessen# Loch 12 der Stift 8 frei hindurchtreten kann, abstätzt. Dieser Stift 8 tritt auch weiter durch ein Loch in der Sp(#rrfeder 13, die die Tendenz hat, sich etwas in Richtung Ales dargestellten Pfeiles zu bewegen. Bei abgeklappter Andruckrolle wird sie an dieser Bewegung durch den Flansch 16 am Stift 8 gehindert. WieJargestellt, ist die am Ende der Feder 13 befestigte Sperrklinke 14 außer Eingriff mitder Rastscheibe 15, da der Flansch 1.6 in der gezeichneten Lage des Stiftes 8 die Feder 13 nach oben abbiegt. Die Rastscheibe 15 ' ist mit dem Schalthebel ig starr verbunden. Dieser Hebel ig wird durch die Feder 17 in die mit W bezeichnete Wiedergabe-Stellung gezogen.Fig. I illustrates an embodiment of the subject matter of the invention. A support device 5 for the rubber pressure roller 6 is attached by means of the hinge 4 to the head support housing i, which contains the magnetic head 2 serving as both a speaking and a hearing head, and the drive roller 3. This carrying device is shown in a state in which it has been folded down by i8a0 '. An inwardly extending projection 7 is attached to the support device 5 , which moves the pin 8 downwards when it is closed, against the action of the spring 9, on the one hand against the flange io, on the other hand against the abutment ii, through its # hole 12 of the pin 8 can freely pass through, is removed. This pin 8 also passes through a hole in the spring 13, which has the tendency to move somewhat in the direction of the arrow shown. When the pressure roller is folded down, this movement is prevented by the flange 16 on pin 8. As shown , the pawl 14 attached to the end of the spring 13 is out of engagement with the locking disc 15, since the flange 1.6 bends the spring 13 upwards in the position shown of the pin 8. The locking disc 15 ' is rigidly connected to the switching lever ig is pulled by the spring 17 into the playback position marked W.
Die Fig. 2 zeigt die Stellung des Schalters bei geschlossener Klappe 5. Der Schalter ig, befindet sich noch in der Wiedergabe-Stellung. Die Klinke 14 liegt auf der Rastscheibe 15 auf. Es ist also nur Wiedergabebetrieb möglich, solange das Gerät-durch Umklappen der Tragvorrichtung für die Gummiandruckrolle eingeschaltet ist.2 shows the position of the switch when the flap 5 is closed. The switch ig is still in the playback position. The pawl 14 rests on the locking disk 15 . Playback mode is therefore only possible as long as the device is switched on by folding down the carrying device for the rubber pressure roller.
Wenn nun beabsichtigt ist, eine Aufnahme zu machen, muß der Schalter ig in die imit A bezeichnete Aufnahme-Stellung gegen die Wirkung der Feder 17 bewegt werden, wie dies die Fig. 3 veranschaulicht. Dabei -dreht sich die Rastscheibe 15 SO weit nach rechts, daß unter der Wirkung der Federspannun,g,der Feder 13,die Klinke 14 sich hinter den Ansatz iS der Rastscheibe 15 legen kann. Der Schalter ig wird dadurch in der Lage Aufnahme gehalten. Wenn jetzt !die Klappe 5 geöffnet wird, bewegt sich infolge der Wirkung der Feder 9 der Stift 8 nach- oben. Der Flan-sch 16 nimmt dann die Feder 13 mit. Die Klinke 14 rastet aus. Der Schalter ig springt aus der Stellung A in die Stellung W zurück.If it is now intended to make a recording, the switch ig must be moved into the recording position indicated by A against the action of the spring 17, as FIG. 3 illustrates. The locking disk rotates 1 5 SO far to the right that, under the action of the spring tension, g, the spring 13, the pawl 14 can lie behind the shoulder iS of the locking disk 15. The switch ig is held in the recording position. If the flap 5 is now opened, the pin 8 moves upwards as a result of the action of the spring 9. The flange 16 then takes the spring 13 with it. The pawl 14 disengages. The switch ig jumps back from position A to position W.
