Description
Seitlich federnde Filmführung für im Bipack zu belichtende Filme Die Erfindung geht aus von einer seitlich federnden Filmführung für im Bipack zu belichtende Filme für Mehrfarbenaufnahmen. Erfindungsgemäß ist in einer solchen Filmführung die seitliche Lage der Filme bei ihrem Durchgang durch das Bildfenster, in dem sie Fläche auf Fläche aufeinanderliegen, für beide Filme je durch feste und federnde Seitenanschläge festgelegt. Dadurch wird erreicht, daß auch bei Filmen mit Breitenunterschieden etwa infolger Schrumpfung die Lage der Teilbilder auf den Filmen eindeutig bestimmt ist, so daß diese ohne Schwierigkeiten wieder zur Deckung gebracht werden können. Bei einer bekannten federnden Führung mit gemeinsamen Führungsschienen für beide Filme lassen sich solche Breitenunterschiede nicht in dieser Weise beherrschen, da sich die Führung immer nur auf eine Filmbreite einstellen kann.Laterally springy film guide for films to be exposed in a bipack Die The invention is based on a laterally resilient film guide for those to be exposed in a bipack Films for multicolor recordings. According to the invention is in such a film guide the lateral position of the films as they pass through the picture window in which they are Surface on surface lie on top of one another, for both films by means of firm and springy Side stops set. This ensures that even with films with differences in width The position of the partial images on the films is clearly determined by shrinkage, for example is, so that they can be brought back into congruence without difficulty. In a known resilient guide with common guide rails for both Films cannot control such differences in width in this way, since the guide can only adjust to one film width.
Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch in Abb. i im Querschnitt, in Abb. 2 in Vorderansicht und in Abb.3 im Längsschnitt dargestellt.The drawing shows an embodiment of the subject matter of the invention schematically in Fig. i in cross section, in Fig. 2 in front view and in Fig. 3 in Longitudinal section shown.
Mit i und 2 sind die beiden Filme bezeichnet, auf denen, wie bekannt, z. B. verschieden licht- und farbempfindliche Schichten in der Weise verteilt sind, ' daß mit einer Aufnahme drei Teilbilder erhalten werden, indem auf dem einen Film eine Schicht und auf dem anderen Film zwei Schichten verteilt sind, wobei die dem Objektiv zugekehrte Schicht am durchsichtigsten ausgebildet ist.With i and 2 the two films are designated, on which, as is known, z. B. different light- and color-sensitive layers are distributed in such a way 'that with one recording three partial images are obtained by on the one film one layer and on the other film two layers are distributed, the dem Objectively facing layer is most transparent.
Wie aus den Abbildungen ersichtlich, läuft jeder Film auf einer Unterlage 3, welche übereinanderliegen und von denen jede auf der einen Längsseite mit festen Anschlägen q., versehen ist. Mittels beweglicher federnder Anschläge 5, 5' auf der gegenüberliegenden Längsseite werden die Filme ohne Spielraum gegen ihre festen Anschläge angedrückt, wodurch ihre Seitenlage festgelegt ist. Die Anschläge q', 5' der oberen Führung sind am Bildfenster .außerhalb desselben angeordnet, so daß die beiden Filme i, 2 während der Aufnahme durch die üblichen Mittel flach aufeinandergedrückt werden können.As can be seen from the images, each film runs on a base 3, which are superimposed and each of which is fixed on one long side Stops q., Is provided. By means of movable resilient stops 5, 5 'on the opposite long side, the films are fixed with no leeway against their Stops pressed, whereby their lateral position is determined. The attacks q ', 5 'of the upper guide are arranged outside the same on the picture window, so that the two films i, 2 pressed flat against one another by the usual means during the recording can be.
