Description

Den Gegenstand der vorliegenden Erfindung bildet eine weitere Ausgestaltung photographischer Kameras, an denen Marken angeordnet sind, die bei der Aufnahme auf der lichtempfindlichen Schicht wiedergegeben werden, nach Patent 334215, durch die eine Vereinfachung der Markeneinrichtung solcher Kameras herbeigeführt wird.The subject of the present invention forms a further embodiment of the photographic Cameras on which marks are arranged which are reproduced on the light-sensitive layer during the recording are, according to patent 334215, by simplifying the branding of such Cameras is brought about.

Nach der vorliegenden Erfindung läßt sich das mit dem Gegenstand des Hauptpatentes angestrebte Ziel bereits dadurch erreichen, daß man ^für die gesamten in einer Kamera nach Patent 334215 befindlichen Hilfsobjektive, für deren jedes bei dem Gegenstand des Hauptpatentes eine besondere Marke vorgesehen wird, eine einzige Marke, und zwar am Ort des Kameraobjektivs anordnet. Diese Marke kann beispielsweise aus einem Strichkreuz o. dgl. bestehen, das man dannAccording to the present invention, this can be done with the subject matter of the main patent Achieve the desired goal already by having ^ for the whole in one camera according to patent 334215 located auxiliary lenses, for each of which in the subject of the Main patent a special trademark is provided, a single trademark, namely arranged at the location of the camera lens. This brand can for example consist of a Bar cross or the like exist, which one then

ao zweckmäßig auf einer der Blendenebene des Kameraobjektivs benachbarten Linsenfläche dieses Objektivs anbringt. Eine besonders einfache, in vielen Fällen genügende Einrichtung erhält man jedoch, wenn man die abzubildende Marke von der Öffnung des Kameraobjektivs selbst bilden läßt.ao expediently on a lens surface adjacent to the diaphragm plane of the camera objective attaching this lens. A particularly simple setup, which in many cases is sufficient you get, however, if you look at the mark to be imaged from the opening of the camera lens make yourself.

In der Zeichnung ist ein Ausführungsbeispiel einer der Erfindung entsprechend ausgestatteten Kamera in einem die optische Achse derselben enthaltenden Schnitt (Fig. 1) und in einem senkrecht zur optischen Achse durch das Kameraobjektiv geführten Schnitt (Fig. 2) dargestellt. Ein Gehäuse a, das, um auf einem Stativ befestigt werden zu können, am Boden mit einem Gewindestutzen b versehen ist, trägt an seinem vorderen Ende ein Objektive und an seinem hinteren Ende einen Rahmend, der zum Halten einer Kassette bestimmt ist. Die Ebene, in die die lichtempfindliche Schicht einer Platte, die sich in einer in den Rahmen eingeschobenen Kassette befindet, zu liegen kommt, ist mit X-X bezeichnet. Das Objektiv ist an dem Gehäuse fest angeordnet und sein Abstand von dem Kassettenrahmen ist nicht veränderbar. Im Innern des Gehäuses α sind vier (davon drei in der Zeichnung sichtbare) Linsensysteme, deren jedes aus einem einzigen Glied e besteht, so angeordnet, daß sie in gewissen Grenzen angenähert senkrecht zur optischen Achse der Kamera und angenähert senkrecht zur Ebene X-X verstellbar sind. Die von den Hilfsobjektiven e abzubildende Marke besteht hier aus einem auf der mit c1 bezeichneten, der Blende c2 des Kameraobjektivs c benachbarten Lmsenfläche dieses Objektivs angebrachten Strichkreuz c3. Die Bilder dieser Marke werden hierbei an solchen Stellen der Ebene X-X entworfen, daß der Schnittpunkt derjenigen beiden Geraden, deren jede zwei sich einander gegenüberliegende Bilder miteinander verbindet, denIn the drawing, an embodiment of a camera equipped according to the invention is shown in a section containing the optical axis thereof (FIG. 1) and in a section (FIG. 2) guided through the camera lens perpendicular to the optical axis. A housing a, which, in order to be able to be mounted on a tripod , is provided with a threaded connector b at the bottom, carries an objective at its front end and a frame end which is intended to hold a cassette at its rear end. The plane in which the light-sensitive layer of a plate, which is located in a cassette inserted into the frame, comes to lie is denoted by XX. The lens is fixedly arranged on the housing and its distance from the cassette frame cannot be changed. Inside the housing α four lens systems (three of which are visible in the drawing), each of which consists of a single member e , are arranged so that they can be adjusted within certain limits approximately perpendicular to the optical axis of the camera and approximately perpendicular to the plane XX. The mark to be imaged by the auxiliary lenses e here consists of a line cross c 3 attached to the lens surface of this lens labeled c 1 and adjacent to the diaphragm c 2 of the camera lens c . The images of this mark are designed in such places of the plane XX that the intersection of those two straight lines, each of which connects two opposing images with each other, the

Punkt bestimmt, in dem die optische Achse der Kamera die Ebene X-X trifft.Determines the point at which the optical axis of the camera meets the plane XX.
