Description

Gegenstand der Erfindung ist eine Verbesserung an Lichttonsprechmaschinen mit endlosem bandförmigem Lautschriftträger, auf dem die Aufzeichnungen in Form einer Spirale aufgezeichnet sind.The subject of the invention is an improvement on phono speaking machines with an endless tape-shaped phonetic carrier on which the recordings are in the form of a spiral are recorded.

Hierbei müssen Belichtungslampe und Photozelle während des Spiels allmählich quer zur Laufrichtung des Bandes verschoben werden. Zu diesem Zweck hat man bereitsThe exposure lamp and the photocell must gradually increase during the game can be moved transversely to the direction of travel of the belt. For this purpose one already has

ίο Belichtungslampe und Photozelle auf eine gemeinsame Grundplatte gesetzt, die mittels Schraubenspindel und Wandermutter verschoben wird. Diese Ausbildung des Gerätes bedingt ein verhältnismäßig großes Gehäuse, da für die Verschiebung der Grundplatte neben dem Tonband ein zusätzlicher, der Breite des Tonbandes entsprechender Raum vorgesehen sein muß. Da man bei endlosen Tonbändern zweckmäßig mit solchen größererίο Exposure lamp and photocell placed on a common base plate, which by means of Screw spindle and traveling nut is moved. This design of the device requires a relatively large housing, there is an additional, the Width of the tape appropriate space must be provided. Since one at endless Tapes appropriate with larger ones

ao Breite arbeitet, um bei kurzen Bändern eine lange Spieldauer zu erhalten, ist der Raumbedarf unerwünscht groß.Ao width works, in order to get a long playing time with short tapes, the space requirement is undesirably large.

Erfindungsgemäß- werden Photozelle und Belichtungslampe durch gesonderte Wander-According to the invention, the photocell and the exposure lamp are

«5 muttern übereinstimmend fortbewegt, so daß sich diese beiden Abtastelemente stets gegenüber befinden, ohne die Baulänge der Einrichtung wesentlich über die Tonbandbreite erhöhen zu müssen,«5 nuts moved in unison, so that these two scanning elements are always opposite, without the overall length of the device having to significantly increase the audio bandwidth,

In der Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsform schematisch dargestellt. Abb. 1 zeigt eine Vorderansicht, Abb. 2 eine Seitenansicht und Abb. 3 eine Draufsicht (Schnitt A-B). In the drawing, the subject matter of the invention is shown schematically in an exemplary embodiment. Fig. 1 shows a front view, Fig. 2 shows a side view and Fig. 3 shows a plan view (section AB).

Über die Walzen 1 und 2 ist das endlose Film- oder Papierband 3 gelegt, in dessen Lochreihen 4 die Zähne 5 der Walzen eingreifen. Ein Schlitten 6 ist auf Stangen 7 und 8 geführt und wird durch eine Schraubenspindel 9 fortlaufend seitlich verschoben. Schlitten 6 trägt die Beleuchtungslampe 10. Ein zweiter Schlitten 11 ist in derselben Weise auf Stangen 12 und 13 geführt und trägt die Photozelle 14. Schlitten 11 wird durch eine Schraubenspindel 15 seitlich verschoben und genau so schnell wie Schlitten 6 bewegt. Eine Triebwelle 16, an der die Einrichtung angetrieben werden möge, steht über Zahnräder iy und 18 mit Spindel 9 in Verbindung, .ebenso über Zahnräder 19 und 20 mit Spindel 15.The endless film or paper tape 3 is placed over the rollers 1 and 2, the rows of holes 4 in which the teeth 5 of the rollers engage. A slide 6 is guided on rods 7 and 8 and is continuously shifted laterally by a screw spindle 9. Carriage 6 carries the lighting lamp 10. A second carriage 11 is guided in the same way on rods 12 and 13 and carries the photocell 14. Carriage 11 is shifted laterally by a screw spindle 15 and is moved just as fast as carriage 6. A drive shaft 16, on which the device may be driven, is connected to the spindle 9 via gears iy and 18, and also via gears 19 and 20 to the spindle 15.
