Description
Es ist bei solchen Kopiereinrichtungen bekannt, sie mit einem besonderen Lichtdurchlaß zu versehen, der längs der beiden Ränder der Tonspur des Positivs eine lichtundurchlässige Einfassung erzeugt. Bei diesen bekannten Einrichtungen wird ein Tonbildpositiv durch einen photographischen Kopierprozeß von einem Negativ erhalten und die links und rechts der Tonspur liegenden lichtundurchlässigen Einfassungen durch eine Vorrichtung erzeugt, die den Positivfilm auf der Kopierlichtseite links und rechts der Tonspur in je einem Streifen belichten.It is known for such copiers to use a special one To provide light passage along the two edges of the sound track of the positive creates an opaque border. In these known facilities becomes an audio image positive by a photographic copying process from a negative and the opaque bezels left and right of the soundtrack generated by a device that left the positive film on the copy light side and to the right of the soundtrack in one strip each.
Diese bekannte Einrichtung mit Lichtdurchlaß für die Einfassung auf der Kopierlichtseite des Positivs hat den Nachteil, daß durch die Belichtung zur Erzeugung der Einfassung die Belichtung der Tonspur gestört werden kann.This known device with light passage for the enclosure the copy light side of the positive has the disadvantage that the exposure to Creation of the bezel can interfere with the exposure of the soundtrack.
Das Wesen der vorliegenden Erfindung liegt darin, dah der die Einfassung der Tonspur erzeugende Lichtdurchlaß auf der der Kopierseite des Positivs entgegengesetzten Seite angebracht, durchleuchtet und mittels eines Objektivs auf die Rückseite des Positivs projiziert wird.The essence of the present invention is that of the bezel the light transmission producing the soundtrack is on the opposite side of the positive to the copy side Side attached, X-rayed and with a lens on the back of the Is projected positively.
Dadurch wird erreicht, daß die Belichtung zur Erzeugung der Einfassung die Belichtung der Tonspur nicht stören kann.This ensures that the exposure to produce the border cannot interfere with the exposure of the soundtrack.
Fig. r stellt in Ansicht ein mit der Einrichtung nach der Erfindung hergestelltes Positiv dar, während Fig.2 die Einrichtung nach der Erfindung schematisch veranschaulicht.Fig. R shows a view with the device according to the invention produced positive, while Fig.2 shows the device according to the invention schematically illustrated.
Der Negativtonstreifen N wird durch Kopierlampe L1 auf das Positiv P kopiert. An dem Tonspurbelichtungsfenster F oder in seiner Nähe wird ein Doppelspalt Sp mit Hilfe einer Optik 0 auf die Rückseite eines Positivfilms abgebildet. Der Spalt Sp wird mit Hilfe einer Lichtquelle L2 und eines Kondensators beleuchtet und ist so ausgeführt, daß er auf die Tonspur des zu kopierenden Negativs, von geringer Kantenüberdeckung abgesehen, kein Licht von der Lampe L" hindurchläßt. Auch die Teile des Positivs, welche Bildteile tragen, werden durch diesen Spalt vor der Belichtung durch die Latnpe L= geschützt.The negative tone stripe N is applied to the positive by the copy lamp L1 P copied. A double slit appears at or near the audio track exposure window F Sp imaged on the back of a positive film with the aid of an optic 0. Of the Gap Sp is illuminated with the aid of a light source L2 and a capacitor is designed so that it is on the sound track of the negative to be copied, of less Apart from the edge overlap, no light from the lamp L "lets through. The Parts of the positive which carry image parts are passed through this gap before exposure protected by the Latnpe L =.
