Description

  

   <Desc/Clms Page number 1> 
 



  Photographische Kamera, an der Marken angeordnet sind, die bei der Aufnahme auf der lichtempfindlichen Schicht wieder gegeben werden, um den Punkt festzulegen, in dem diese Schicht von der optischen Achse getroffen wird.

 so einzustellen, dass ihr Bild auf   die gewünschte Stelle   der Platte fällt. Im unteren Teil der Kamera ist ebenfalls ein   Röhrchen e   angebracht, das jedoch starr an der Kamera befestigt ist. 



  Dieses Röhrchen trägt an seinem hinteren Ende eine kleine Sammellinse g, die exzentrisch ist, so dass ihre Achse nicht mit der des Röhrchens e zusammenfällt. Die Sammellinse ist in einer Fassung gl angebracht, die beweglich in dem Röhrchen e steckt ; eine Klemmschraube g2 dient zum Festklemmen der Sammellinse. Die am'vorderen Teil dieses Röhrchens sitzenden Teile h, i,   io   und j stimmen mit den entsprechend bezeichneten oben in der Kamera angeordneten Teilen überein. Ein   Beleuchtungsprisma   ist hier entbehrlich. Zum Einstellen des Markenbildes ist es hier nur nötig, den Hohlzylinder k und die Sammellinse g samt ihrer Fassung gl in dem Röhrchen   e   durch Drehen entsprechend einzustellen.

   Man wird bei dem gezeichneten Beispiel die beiden   Markenbilder   so einstellen, dass sie die Endpunkte einer Strecke bilden, in deren Mitte der Punkt 
 EMI2.1 
 Schicht von der optischen Achse getroffen wird, dadurch gekennzeichnet, dass in der Kamera für jede Marke ein Hilfsobjektiv angeordnet ist, das dazu dient, ein Bild der Marke auf der lichtempfindlichen Schicht zu entwerfen.

 set so that your image falls on the desired place on the plate. In the lower part of the camera there is also a tube e, which, however, is rigidly attached to the camera.



  At its rear end, this tube carries a small converging lens g which is eccentric so that its axis does not coincide with that of the tube e. The converging lens is mounted in a mount gl which is movably inserted in the tube e; a clamping screw g2 is used to clamp the converging lens. The parts h, i, io and j located on the front part of this tube correspond to the correspondingly designated parts arranged at the top of the camera. A lighting prism is not necessary here. To set the brand image, it is only necessary here to adjust the hollow cylinder k and the converging lens g together with their mount gl in the tube e accordingly by turning.

   In the example shown, you will set the two mark images in such a way that they form the end points of a line with the point in the middle
 EMI2.1
 Layer is hit by the optical axis, characterized in that an auxiliary lens is arranged in the camera for each mark, which is used to design an image of the mark on the light-sensitive layer.

 

Claims (1)

2. Kamera nach Anspruch i, dadurch gekennzeichnet, dass jede Marke um die optische Achse des zugehörigen Hilfsobjektivs und um eine zur optischen Achse dieses Hilfsobjektivs nicht parallele Achse drehbar ist. 2. Camera according to claim i, characterized in that each mark can be rotated about the optical axis of the associated auxiliary lens and about an axis which is not parallel to the optical axis of this auxiliary lens. 3. Kamera nach Anspruch i, dadurch gekennzeichnet, dass eine Marke und das zugehörige Hilfsobjektiv je um eine von zwei einander parallelen Achsen drehbar sind, die gegen die Verbindungslinie der Marke und des optischen Mittelpunktes des Hilfsobjektives geneigt sind. 3. A camera according to claim i, characterized in that a mark and the associated auxiliary lens are each rotatable about one of two mutually parallel axes which are inclined against the connecting line of the mark and the optical center of the auxiliary lens.
