Description
Die Erfindung betrifft eine besonders zweckmäßige und vorteilhafte Ausgestaltung des im Hauptpatent 555356 beschriebenen Kinoaufnahmeapparates, und zwar besteht die Erfindung darin, daß· die federnde Andruckplatte für das Filmband an' dem Aufnahmeapparat selbst befestigt ist und beim Einsetzen der Kassette in die Ausnehmung derselben hinter das Filmband faßt, ohne daß dieses seine Lage verändert. Dadurch wird eine Kassette einfachster Bauart geschaffen, die keine empfindlichen, der Filmführung dienenden Teile aufweist, die durch das Auswechseln des Films in der Dunkelkammer beschädigt werden könnten. Im besonderen besteht der Vorteil des Erfindungsgegenstandes darin, daß in der bisher üblichen Weise die Führungsteile des Fiknkanals im Apparat verbleiben können und trotzdem ein besonderes Einfädeln des Films beim Einlegen der Kassette nicht erforderlich ist.The invention relates to a particularly useful and advantageous embodiment of the im Main patent 555356 described cinema recording apparatus, the invention consists in that · the resilient pressure plate for the film tape is attached to 'the recording apparatus itself and when inserting the Cassette grips in the recess of the same behind the film tape without this his Changed situation. This creates a cassette of the simplest design that does not contain any sensitive, has parts that are used to guide the film and that will be damaged by changing the film in the darkroom could. In particular, the advantage of the subject matter of the invention is that in the The previously usual way the guide parts of the Fiknkanals can remain in the apparatus and Nevertheless, a special threading of the film when inserting the cassette is not necessary is.
Die Zeichnung veranschaulicht den Erfindungsgegenstand in einem Ausführungsbeispiel an einem Kinoapparat sonst bekannter Bauart, und zwar zeigt Fig. 1 einen Kinoapparat in Draufsicht mit geöffnetem Deckel und Fig. 2 einen Kinoapparat in Seitenansicht. Die in den Apparat einzulegende Kassette 1 hat an der Filmbelichtungsstelle, also dort, wo der Film aus der Kassette austritt, eine im wesentlichen rechteckige Ausnehmung 25, in welche beim Einlegen der Kassette in den Apparat die hinter dem Bildfenster 18 angeordnete Andruckplatte 4' .eingreift, so daß der aus dem Kanal 16 aus der Kassette austretende und in den Kanal 17 wieder in die Kassette eintretende Film zwischen die fest mit dem Apparat verbundene Führungsfläche 19 und die Andruckplatte 4' gelangt.The drawing illustrates the subject matter of the invention in an exemplary embodiment on a cinema apparatus of an otherwise known type, namely FIG. 1 shows a cinema apparatus in plan view with the lid open and FIG. 2 shows a cinema set in side view. The cassette 1 to be inserted into the apparatus has at the film exposure point, i.e. there, where the film emerges from the cassette, a substantially rectangular recess 25, in which when the cassette is inserted into the apparatus, the one arranged behind the picture window 18 Pressure plate 4 '. Engages, so that the emerging from the channel 16 from the cassette and in the channel 17 re-entering the cassette between the film with the apparatus connected guide surface 19 and the pressure plate 4 'arrives.
Die Andruckplatte 4' ist an der Gehäusezwischenwand 21 verschieblich befestigt.The pressure plate 4 'is on the partition between the housing 21 slidably attached.
Das Einlegen der Kassette erfordert also bei der beschriebenen Anordnung keine besonderen Handgriffe, und auch der Film behält infolge der für das Eingreifen der Andruckplatte vorgesehenen Ausnehmung unverändert seine Lage bei. Die Filmkassette selbst besteht aus einem einfachen Blechgehäuse und läßt sich in einfachster Weise herstellen, so daß sie keine empfindlichen mechanisehen Teile enthält.The insertion of the cassette does not require any special features in the described arrangement Handles, and also the film retains due to the engagement of the pressure plate provided recess unchanged its position. The film cassette itself consists of a simple sheet metal housing and can be manufactured in the simplest possible way, so that they do not see any sensitive mechanisms Contains parts.
