Description

DEUTSCHESGERMAN

Um einen synchronen Ablauf von Bild- und Tongeräten mit getrennten Antriebsmotoren zu erreichen, bedarf es besonderer Einrichtungen.In order to achieve a synchronous sequence of picture and sound devices with separate drive motors, special facilities are required.

Eine bekannte Anordnung für diesen Zweck ist in Form des sogenannten phonischen Rades bekannt, bei dem der Motor des zu synchronisierenden Gerätes durch Magnetfelder periodisch abgebremst wird. Eine solche Einrichtung erfordert erheblichen Energiebedarf und ist deshalb insbesondere bei transportablen batteriebetriebenen Einrichtungen — wie sie z. B. bei der Tonfilmaufnahmetechnik verwendet werden — ungeeignet. Auch andere bekannte Einrichtungen bedienen sich für die Tonbildsynchronisation sogenannter Regel-Bremseinrichtungen. Diese, gleichgültig, ob sie als elektromagnetische Wirbelstrombremse oder als elektromagnetische Backenbremse oder auf eine andere übliche Art wirksam sind, erfordern einen erhöhten Energiebedarf, wodurch entsprechend der hohen Reglerleistungen die Steuerkontakte übermäßig hoch beansprucht werden. Bei gleichzeitiger Magnetonaufnahme oder -wiedergabe treten infolge der relativ hohen Steuer- oder Reglerleistungen elektromagnetische und/oder hochfrequente Störungen in der Vertonung auf, indem die Streufelder der Bremsreglermagnete oder die Schaltfunken der Steuerelemente auf die Magnetköpfe bzw. auf das Tonband oder auf die Verstärkereinrichtung nachteilig einwirken. Zur Beseitigung dieser Störungen sind besondere Maßnahmen erforderlich.A known arrangement for this purpose is known in the form of the so-called phonic wheel at which the motor of the device to be synchronized is periodically slowed down by magnetic fields. One Such a device requires considerable energy and is therefore particularly portable, battery-operated Facilities - such as B. used in sound film recording technology - unsuitable. Other known devices also use what are known as audio image synchronization Control braking devices. These, regardless of whether they are used as an electromagnetic eddy current brake or as a electromagnetic shoe brake or are effective in any other usual way, require an increased Energy requirement, which puts excessive strain on the control contacts due to the high controller power will. With simultaneous recording or playback of Magneton occur as a result of the relative high control or regulator performance, electromagnetic and / or high-frequency interference in the soundtrack by the stray fields of the brake regulator magnets or the switching sparks of the control elements the magnetic heads or the tape or the amplifier device act disadvantageously. For elimination special measures are required for these disturbances.

Gemäß vorliegender Erfindung werden diese Nachteile und damit der erforderliche Mehraufwand dadurch vermieden, indem eine Einrichtung zum synchronen Ablauf von Bild- und Tongeräten mit getrennten Antrieben, bei der die Synchronität durch vom Tonträger ausgelöste Impulse hergestellt wird, die zur Steuerung des Antriebsmotors des Bildgerätes dienen, in der Weise arbeitet, daß die Synchronimpulse zur Erzeugung eines Magnetfeldes benutzt werden, in welchem sich ein über eine Feder mit dem Motor des Bildgerätes gekuppelter Anker befindet, der in Abhängigkeit von den Synchronimpulsen und von seiner Lage im Magnetfeld einen im Stromkreis des Antriebsmotors des zu synchronisierenden Gerätes liegenden Schalter steuert, wobei der eine Schaltkontakt dieses Schalters starr mit dem Anker und der andere Schaltkontakt starr mit der Welle des Antriebsmotors verbunden ist.According to the present invention, these disadvantages and thus the additional effort required are thereby eliminated avoided by a device for the synchronous operation of picture and sound devices with separate Drives in which the synchronicity is established by impulses triggered by the sound carrier, which are used to control the drive motor of the imaging device, works in such a way that the sync pulses can be used to generate a magnetic field in which a spring with the motor of the Image device coupled armature is located, which depends on the sync pulses and on his Position in the magnetic field is one in the circuit of the drive motor of the device to be synchronized Switch controls, one switching contact of this switch rigidly with the armature and the other Switching contact is rigidly connected to the shaft of the drive motor.

Der Erfindungsgegenstand wird nachstehend an Hand eines Ausführungsbeispiels näher beschrieben.The subject matter of the invention is described in more detail below using an exemplary embodiment.

nehmende oder tragende perforierte Tonband 1, dessen Antrieb in der Abbildung nicht dargestellt ist, läuft über eine Zahntrommel 2, die mit einem Kontaktgeber 3 starr verbunden ist. Der Kontaktgeber 3 steuert über die Stromabnehmer 4β und 4 b einen aus der Batterie 5 und einer Magnetspule 6 bestehenden Stromkreis. Die Magnetspule 6 ist auf einen Magnetkern 7 gewickelt, zwischen dessen beiden Polen 8 a und 8 b sich ein Anker 9 befindet. Letzterer ist frei drehbar auf der \'erlängerten Welle 10 des Motors 11 gelagert, der zum Antrieb eines nicht dargestellten Bildgerätes dient. Mit der verlängerten Welle 10 ist ein Arm 12 fest verbunden. An ihm ist isoliert ein Kontakt 13 angeordnet, der einem Kontakt 14 gegenüberliegt, welcher mit Hilfe eines Winkels 15 am Anker 9 befestigt ist. Der Anker 9 und die Welle 10 sind durch eine Feder 16, die im Ausführungsbeispiel am Arm 12 und am Winkel 15 befestigt ist, kraftschlüssig verbunden.The receiving or carrying perforated tape 1, the drive of which is not shown in the figure, runs over a toothed drum 2 which is rigidly connected to a contactor 3. The contactor 3 controls via the current collector 4β and 4 b a from the battery 5 and a coil 6 existing circuit. The magnetic coil 6 is wound onto a magnetic core 7, between the two poles 8 a and 8 b of which an armature 9 is located. The latter is freely rotatably mounted on the elongated shaft 10 of the motor 11, which is used to drive an imaging device, not shown. An arm 12 is firmly connected to the elongated shaft 10. A contact 13 is arranged on it in an insulated manner and faces a contact 14 which is fastened to the armature 9 with the aid of an angle 15. The armature 9 and the shaft 10 are non-positively connected by a spring 16 which, in the exemplary embodiment, is fastened to the arm 12 and to the bracket 15.

Auf der verlängerten Welle 10 sitzen zwei Schleifringe 17 ο und 17 b, die mit den Kontakten 13 und 14 verbunden sind. Diese liegen in einem Stromkreis, der aus der Batterie 5 und der Wicklung des Motors 11 gebildet wird.Two slip rings 17 o and 17 b, which are connected to the contacts 13 and 14, sit on the extended shaft 10. These lie in a circuit which is formed from the battery 5 and the winding of the motor 11.

Die Wirkungsweise der Einrichtung ist folgende: Im ungeregelten Zustand sind die Geschwindigkeiten von Ton- und Bildgerät so abgestimmt, daß die Drehzahl des Bildgerätes ein bis zwei Bilder pro Sekunde vorauseilt, d. h., es wird von einer sogenannten Abwärtsregelung Gebrauch gemacht.The mode of operation of the device is as follows: The speeds are in the unregulated state of the sound and video device so that the speed of the video device is one to two frames per second rushes ahead, d. That is, use is made of what is known as a down regulation.

Wenn die Stromabnehmer 4 a und 4& durch ein Kontaktsegment des Kontaktgebers 3 kurzgeschlossen werden, fließt ein Batteriestrom durch die Wicklung 6 des Magneten 7. Bei Synchronität beider Geräte wird dieser Impuls in dem Augenblick ausgelöst, wo der Anker 9 die in Abb. 2 gestrichelt dargestellte Lage einnimmt, d. h. wo er im magnetisch neutralen Bereich, dargestellt durch den Winkel a, liegt, so daßWhen the current collectors 4 a and 4 & are short-circuited by a contact segment of the contactor 3, a battery current flows through the winding 6 of the magnet 7. If both devices are synchronized, this pulse is triggered at the moment when the armature 9 is the one shown in Fig. 2 in dashed lines Position, ie where it is in the magnetically neutral area, represented by the angle a , so that

keinerlei Wirkung auf den Anker ausgeübt wird. Die Kontakte 13 und 14 bleiben geschlossen. Eilt dagegen der Kameramotor voraus, so ist der Anker 9 beispielsweise im Augenblick des Steuerimpulses um einen Winkel β aus dem magnetisch neutralen Feld herausgetreten. Durch die Wirkung des magnetischen Feldes wird er in Richtung der neutralen Zone zurückgezogen, wodurch nach Überwindung der Kraft der Feder 16 eine öffnung der Kontakte 13 und 14 bzw. eine Öffnung des Stromkreises des Motors 11 erfolgt. Die jeweilige Größe des Winkelbereiches β der Ankervorauseilung, die der Vorauseilung des Motors 11 proportional ist, steuert dabei die Zeitdauer der Kontaktöffnung bzw. der Motorabschaltung. Um die Ansprechempfindlichkeit der Regeleinrichtung zu erhöhen, hat es sich als zweckmäßig erwiesen, den Anker 9 als polarisierten Magneten auszubilden. Patentansprüche-zono effect is exerted on the anchor. Contacts 13 and 14 remain closed. If, on the other hand, the camera motor leads ahead, the armature 9 has stepped out of the magnetically neutral field by an angle β at the moment of the control pulse, for example. Due to the effect of the magnetic field, it is withdrawn in the direction of the neutral zone, as a result of which, after the force of the spring 16 has been overcome, the contacts 13 and 14 or the circuit of the motor 11 are opened. The respective size of the angular range β of the armature advance, which is proportional to the advance of the motor 11, controls the duration of the contact opening or the motor shutdown. In order to increase the responsiveness of the control device, it has proven to be expedient to design the armature 9 as a polarized magnet. Claims-zo 1.
