Beim Tonfilm werden die Lichtschwingungen auf das Filmband in Form von hellen oder dunklen Strichen oder sogenannten Zacken aufgezeichnet. Dieser Erfindung liegt der Gedanke zugrunde, diese Aufzeichnungen in eine Schrift zu übertragen.In the sound film, the light oscillations on the film tape in the form of bright or dark lines or so-called spikes. This invention lies in the Based on the idea of transcribing these notes into writing.
Die durch den Aufnahmeapparat a in bekannter Weise erzeugten Lichtschwingungeii sind anstatt auf den Filmstreifen in einemThe light oscillations ii generated in a known manner by the recording apparatus a are in one instead of on the filmstrip
ίο durch Linse c vergrößerten Maßstab auf eine präparierte Mattscheibe gerichtet. Durch diese Mattscheibe b hindurch treffen die nacheinander folgenden Schwingungen der einzelnen in den Aufnahmeapparat α gesprochenen Buchstaben die rotierende Scheibe d. Diese mit entsprechender Geschwindigkeit rotierende Scheibe d wird hinter der Mattscheibe b vorbeibewegt und besitzt ein Negativ e der gleichen Schwingungsaufzeichnungen der einzelnen Buchstaben in derselben Größe, so daß bei Zusammentreffen gleichgearteter Schwingungen der vom Aufnahmeapparat α ausgehende Lichtstrahl nach der Photozelle/ abgeschirmt wird, wohingegen bei andersgearteten Schwingungen immer noch ein Lichtstrahl die Photozelle f treffen kann. Das auf der Scheibe d angebrachte Negativ e ist in der Aussprache der die Apparatur benutzenden Person hergestellt, damit eine Übereinstimmung der Schwingungen gegeben ist.ίο Enlarged scale through lens c directed onto a prepared focusing screen. Through this ground glass b , the successive vibrations of the individual letters spoken in the recording apparatus α hit the rotating disk d. This disk d , rotating at a corresponding speed, is moved past the ground glass b and has a negative e of the same vibration recordings of the individual letters in the same size, so that when similar vibrations coincide, the light beam emanating from the recording device α is shielded after the photocell /, whereas with other types Vibrations still a light beam can hit the photocell f. The negative e affixed to the disk d is made in the pronunciation of the person using the apparatus, so that the vibrations match.
Der mit der Photozelle / in A^erbindung stehende Stromkreis wird also unterbrochen, sobald die Photozelle / durch Zusammentreffen gleichgearteter Schwingungen in positiver und negativer Atifzeichnung gegen den Lichtstrahl abgeschirmt ist. Bei Unterbrechung dieses Stromkreises wird der Anker g freigelassen und schließt durch Kontakt h einen zweiten Stromkreis, welcher den Anschlag des Typenhebels auf der elektrisch betriebenen Schreibmaschine zu bewirken hat.The electric circuit connected to the photocell / is interrupted as soon as the photocell / is shielded from the light beam by the coincidence of similar vibrations in positive and negative markings. When this circuit is interrupted, the armature g is released and, through contact h , closes a second circuit, which has to bring about the stop of the type lever on the electrically operated typewriter.
Die Scheibe i, welche mit der Scheibe d synchron rotiert, vermittelt durch in genügender Anzahl angeordnete Schleifkontakte k die den einzelnen Lauten entsprechende Verteilung der Stromstöße zur Betätigung der Drucktypen.The disk i, which rotates synchronously with the disk d , mediates, by means of sliding contacts k arranged in a sufficient number, the distribution of the current impulses corresponding to the individual sounds for actuating the printing types.
