Description

Die Nachteile der handelsüblichen Schallplatte, ihre kurze Spieldauer infolge begrenzter Abmessung, das durch die mechanische Abtastung bedingte verhältnismäßig starke Nadelgeräusch und der schnelle Verschleiß können bei Verwendung von Tonfilmstreifen, auf denen die Töne photographisch aufgezeichnet sind, vermieden werden.The disadvantages of the commercially available record, its short playing time as a result of limited Dimensions, the relatively strong needle noise caused by the mechanical scanning and the rapid wear can be avoided when using sound film strips on which the sounds are recorded photographically will.

to Die Wiedergabe solcher Tonfilmstreifen erfolgt nicht durch mechanische Abtastung, sondern durch einen feinen Lichtstrahl mit Hilfe einer Photozelle, Verstärker und Lautsprecher. Hierzu waren bisher besondere Apparate nötig. Der Erfindungsgegenstand bietet demgegenüber die Möglichkeit, jede beliebige Plattensprechmasehine durch Aufsetzen eines Zusatzgerätes auch zur Wiedergabe von Tonfilmstreifen zu verwenden. so Die Gesamtanordnung der Apparatur ist durch die Zeichnung erläutert.to The reproduction of such sound film strips is not carried out by mechanical scanning, but by a fine beam of light with the help of a photocell, amplifier and loudspeaker. Up to now, this required special equipment. The subject of the invention In contrast, it offers the possibility of any record-breaking machine by putting it on an additional device can also be used to reproduce sound film strips. so the overall arrangement of the apparatus is explained by the drawing.

Von einer handelsüblichen Sprechmaschine wird der Plattenteller abgenommen und die Grundplatte α des Zusatzgerätes auf das Werkbrett aufgelegt. Diese trägt die Filmvorratsrolle b, die lichtempfindliche Zelle samt Lichtquelle und Optik c und die Filmaufwickelspule d. Die Filmtransportrolle e wird dabei auf die konische Achse f aufgesteckt, die sonst den Plattenteller trägt. Diese Filmtransportrolle e, über welche der Film g läuft, ist in bekannter Weise als Zackenrolle ausgebildet. Von der durch die Tonaufzeich-■ nungen beeinflußten lichtempfindlichen Zelle führen zwei Leitungen h unter Zwischenschaltung eines geeigneten Verstärkers zu einem Lautsprecher, Als solcher kann eine elektrische Wiedergabeschalldose an Stelle der mechanischen Schalldose an den beweglichen Arm der Sprechmaschine angesetzt werden.The turntable is removed from a commercially available speaking machine and the base plate α of the additional device is placed on the work board. This carries the film supply roll b, the photosensitive cell with light source and optics c and the film take-up spool d. The film transport roller e is attached to the conical axis f , which otherwise carries the turntable. This film transport roller e, over which the film g runs, is designed in a known manner as a tooth roller. From the light-sensitive cell influenced by the sound recordings, two lines h lead to a loudspeaker with the interposition of a suitable amplifier.

Durch zweckentsprechende Ausbildung des Lichttonzüsatzgerätes kanu also innerhalb weniger Minuten die Umwandlung einer normalen Plattensprechmasehine in einen Tonfilmsprechapparat erfolgen, andererseits besteht auch die Möglichkeit, den Apparat jederzeit wieder zur Wiedergabe von Schallplatten verwenden zu können.By appropriate training of the optical additional device canoe so within a few minutes the conversion of a normal record speaker into one Sound film intercom, on the other hand there is also the possibility of using the apparatus to be able to use it again at any time to play records.
