Abstract

The simplified audio magnetic tape recording head position adjustment mechanism consists of a carrier plate mounted on two spring loaded adjustable pedestals. Three adjustable columns or pedestals are used to carry two carrier plates in this case. The simplified mechanism has only one head carrier or chassis plate (4) mounted by adjustable screws (5, 6) on two pedestal columns (2, 3). One of these carries an outer tube (7) with a spring mounted base (9) whilst the other is spring loaded (8) directly between the chassis (1) and carrier plate (4). The angular position of the head (10) and its displacement from the tape (12) can both easily be adjusted by means of arrangement.

Description

Tonkopf-Justiereinrichtung für Tonbandgeräte Bekanntlich wird in Magnettonbandgeräten der - ?- auf einer Justierplatte montiert, die meist in tnehr£rer @@eiheitsgraden verstellbar ist. Oft ist jedoch, um die Justierung zu erleichtern, nur eine Verstellbarkeit hinsichtlich der Höhenlage und der Winkellage des Kopfspaltes zur Banulâc-ricl.tung erwünscht, ohn daß der Kopfspalt aus der Ebene des Tonbandes bewegt wird. Tape head adjustment device for tape recorders is known in Magnetic tape recorders of the -? - mounted on an adjustment plate, which are usually in more is adjustable. Often, however, in order to facilitate the adjustment, only one adjustability with regard to the height and the angular position of the head gap for Banulâc-ricl.tung desired without the head gap from the plane of the tape is moved.

So ist z.B. eine Justiereinrichtung nach Fig. 1 bekannt. Der Tonkopf 10 ist auf den federnden Metallstreifen 13 und 14 befestigt und kann an den Schrauben 15 und 16 in der oben genannten Weise justiert werden. Die feste Lagerung des Metanistreifens 13 an der Säule 18 dient zur Fixierung des Kopfspaltes in der Ebene des Tonbandes. Diese bekannte Lösung ist aufwendig und hat den Nachteil, daß der Kopfspalt durch mangelnde Drehstabilität der Metallstreifen selbst und ihrer Lagerung an den Schrauben 15 und 16 seine Stellt zum Tonband ändern kann.For example, an adjusting device according to Fig. 1 is known. The tape head 10 is attached to the resilient metal strips 13 and 14 and can be attached to the screws 15 and 16 can be adjusted as described above. The fixed storage of the metani strip 13 on the column 18 is used to fix the head gap in the plane of the tape. This known solution is expensive and has the disadvantage that the head gap through Insufficient rotational stability of the metal strips themselves and their storage on the screws 15 and 16 its position can change to tape.

Der Erfindung liegt die Aufgabe zugrunde, eine einfachere Tonkopf-Justiereinrichtung der zuletzt beschriebenen Art zu schaffen, die eine exakt stabile Lage hinsichtlich des Tonkopfspaltes gewähtleistet.The invention is based on the object of a simpler audio head adjustment device to create the last-described type, which is an exactly stable position with regard to the sound head gap is guaranteed.

Diese Aufgabe wird durch die im Anspruch 1 enthaltene Erfindung gelöst.This object is achieved by the invention contained in claim 1.

Die Erfindung wird nachstehend anhand des Ausführungsbeispiels in Fig. 2 erläutert.The invention is illustrated below with reference to the exemplary embodiment in Fig. 2 explains.

In Fig. 2 sind auf der Grundplatte 1 zwei Säulen 2,3 angeordnet.In Fig. 2, two columns 2, 3 are arranged on the base plate 1.

Auf diesen ist, gehalten von den Schrauben 5 und 6, die Justierplatte 4 gelagert. An der Säule 2 drückt eine Wendelfeder 8 die Justierplatte 4 in an sich bei Justiereinrichtungen bekannter Weise gegen den Kopf der Schraube 6. An der Säule 3 liegt die Justierplatte 4 auf dem die Säule umschließenden Rohr 7 auf und kann mit ihm starr verbunden sein. Der Innendurchmesser des Rohres ist dem Säulendurchmesser so angepaßt, daß das Rohr spielfrei verschiebbar ist. Es wird mit der Justierplatte durch eine gespannte Federscheibe 9 gegen den Kopf der Schraube 5 gedrückt.The adjustment plate is held on this by screws 5 and 6 4 stored. On the column 2, a helical spring 8 presses the adjusting plate 4 in itself in the case of adjusting devices, in a known manner, against the head of the screw 6. On the column 3 the adjustment plate 4 rests on the tube 7 surrounding the column and can to be rigidly connected to him. The inside diameter of the pipe is the column diameter adapted so that the tube can be moved without play. It comes with the adjustment plate pressed against the head of the screw 5 by a tensioned spring washer 9.

So läßt sich an den Schrauben 5 und 6 bequem die Höhen- und Winkellage des auf der Platte 4 montierten Tonkopfes 10 mit der Bandführung 17 und dem Kopfspalt 11 justieren.So you can easily adjust the height and angle of the screws 5 and 6 of the tape head 10 mounted on the disk 4 with the tape guide 17 and the head gap 11 adjust.

Die Justierplatte muß so nachgiebig sein, daß sie bei der Justierung auf der gesamten Stirnfläche des Rohres liegen bleibt. Diese Forderung ist jedoch auch bei einer verhältnismäßig wenig nachgiebig ausgebildeten Justierplatte leicht zu erfüllen, denn ihre zur Grundplatte 1 parallele Lage ist im Wesentlichen durch das Rohr 7 auf der Säule 3 vorgegeben und braucht im Bedarfsfall nur geringfügig durch die Schraube 6 korrigiert zu werden. So behält der Tonkopf auch bei Erschütterungen oder Berührung seine stabile Lage. Insbesondere wird ein Kippen in einer zur Bandlaufrichtung senkrechten Ebene vermieden.The adjustment plate must be flexible enough to allow it to be adjusted during adjustment remains on the entire face of the pipe. However, this requirement is easy even with a comparatively less flexible adjustment plate to meet, because their position parallel to the base plate 1 is essentially through the pipe 7 is given on the column 3 and needs only slightly if necessary to be corrected by screw 6. So the tape head retains even in the event of vibrations or touch its stable position. In particular, there is a tilting in one direction to the tape travel direction vertical plane avoided.
