Description
Für band- oder drahtförmige Aufzeichnungs-, insbesondere --\Iagnetogrammträger sind Laufwerke bekannt, mit denen der Aufzeichnungsträger zum Aufzeichnen und Wiedergeben mittels eines Rollenpaares von einem konstant laufenden Motor, vorzugsweise Synchronmotor, an dem Abtast- und/ oder Sprechkopf vorbeigezogen wird. Zum Zurückspulen oder für den Vorlauf mit erhöhter Geschwindigkeit wird der Einfluß des Rollenpaares aufgehoben und statt dessen die jeweiligeAufwickelspule irgendwie angetrieben. Es ist bekannt, bei diesen Leerläufen mit erhöhter Geschwindigkeit den Aufzeichnungsträger außer Kontakt mit den \lagnetisierungsköpfen zu bringen, um unnötigen Verschleiß des Kopfes oder der Köpfe und des Niagnetogrammträgers zu vermeiden. Hierzu ist bereits ein besonderer Bandabheber vorgeschlagen worden, der nach einem anderen Vorschlag durch eine den Magnetisierungsköpfen benachbarte Umlenkrolle gebildet werden kann. In beiden Fällen ist eine zusätzliche Bewegung eines besonderen oder bereits vorhandenen Bauteils erforderlich.For tape or wire-shaped recording, especially magnetogram carriers drives are known with which the recording medium for recording and reproducing by means of a pair of rollers from a constantly running motor, preferably a synchronous motor, is pulled past the scanning and / or speaking head. For rewinding or for the influence of the pair of rollers is canceled when the speed is increased and instead somehow driven the respective take-up reel. It is known, the recording medium except for these idle runs at increased speed Bring contact with the magnetizing heads to avoid unnecessary wear of the head or the heads and the niagnetogram carrier. There is already a special ribbon lifter has been proposed, which after another suggestion by a deflection roller adjacent to the magnetization heads can be formed. In both cases is an additional movement of a special or pre-existing one Component required.
Gemäß der Erfindung wird diese zusätzliche Bedienung und Bewegung bei einem mit Antriebs-und Andruckrolle versehenen Laufwerk für Schallaufzeichnungs-, insbesondere _Iagnetogrammträger, deren Berührung mit dem Sprech- und/oder Wiedergabekopf bei beschleunigtem Vor- oder Zurückspulen aufgehoben wird, dadurch erspart, daß in dem Betriebsfall, in dem die Andruckrolle von der Antriebsrolle abgeschwenkt ist, das Band von den Köpfen Lund der Tonrolle abgehoben ist und daß es in dem Betriebsfall, in dem es von der Andruckrolle gegen die Antriebsrolle gedrii,ckt wird, an den Köpfen anliegt.According to the invention, this additional operation and movement in the case of a drive with a drive and pressure roller for sound recording, in particular _Iagnetogrammträger, their contact with the speaking and / or playback head is canceled with accelerated forward or rewind, saved in that in the operating case in which the pressure roller is pivoted away from the drive roller is, the tape is lifted from the heads L and the tape roll and that in the case of operation, by pressing it against the drive roller by the pressure roller, on the heads is applied.
Dies ist am einfachsten erreichbar, wenn die treibende Motorrolle und der Kopf oder die Köpfe auf derselben Seite des Aufzeichnungsträgers angeordnet sind, die Andruckrolle aber auf der gegenüberliegenden oder, falls die treibende Rolle schwenkbar sein sollte, umgekehrt.This is most easily achieved when the driving motor roller and the head or heads are arranged on the same side of the recording medium are, but the pressure roller on the opposite or, if the driving one Role should be pivotable, vice versa.
Ein Ausführungsbeispiel für den Erfindungsgedanken ist in der Figur, zum Teil schematisch, dargestellt. Der Aufzeichnungsträger i läuft bei Sprechbetrieb von der nicht dargestellten Vorratsspule Tiber eine Umlenkrolle 2, an einem oder mehreren Magnetisierungsköpfen 3 vorbei und wird von dem Rollenpaar ,I. 5 gezogen, von dein ,I die glatte, treibende, 5 die Gutnniiandruckrolle sein möge. Nach Verlassen der letzteren, die um den Punkt 7 schwenkbar angeordnet ist, läuft der Träger i über die Unilenkrolle 6 auf die nicht dargestellte Aufwickelspule auf. Soll beschleunigt vor-oder zurückgespult werden, so wird die Gummiandruckrolle 5 in Pfeilrichtung von der treibenden Rolle 4 fort in die gestrichelt dargestellte Lage geschwenkt, in der sie nicht mehr an dein -Iagnetogrammträger anliegt. Dieser läuft jetzt geradenwegs von der Unilenkrolle 2 zur Leitrolle 6 oder umgekehrt, je nach Aufspulrichtung. Die beiden Stellungen der Andruckrolle 5 sind durch Anschläge fixiert. Die Schwenkung dieser Rolle wird üblicherweise selbsttätig gesteuert, so claß (las erstrebte Ziel des zweckentsprechenden Anlegens oder Abhebens des _Magnetograminträgers ohne besondere Handgriffe gew.-ilirleistet ist.An embodiment for the inventive idea is shown in the figure, partly shown schematically. The recording medium i runs during speech operation from the supply reel Tiber, not shown, a pulley 2, on one or several magnetization heads 3 over and is of the roller pair, I. 5 drawn, of yours, I may be the smooth, driving, 5 the good pressure roller. After leaving the latter, which is arranged pivotably about the point 7, the carrier runs i on the Unilenkrolle 6 on the take-up reel, not shown. Should accelerate are rewound forwards or backwards, the rubber pressure roller 5 is in the direction of the arrow pivoted away from the driving roller 4 into the position shown in dashed lines, in which it is no longer in contact with your magnetogram carrier. This is now running in a straight line from the Unilenkrolle 2 to the guide roller 6 or vice versa, depending on the winding direction. The two positions of the pressure roller 5 are fixed by stops. The panning this role is usually controlled automatically, so class (read goal the appropriate application or removal of the _Magnetogramin carrier without special Handgrips Gew.-ilirleistet is.
