Description

  

  Basisentfernungsmesser für photographische Kameras.    Die Erfindung betrifft einen Basisentfer  nungsmesser für photographische Kameras.  



  Für den Sucher bei photographischen  Kameras wird eine bildverkleinernde Wir  kung angestrebt, um das Gesichtsfeld gut  überblicken zu können, dagegen wird beim  Entfernungsmesser von einer bildverkleinern  den Wirkung abgesehen, um die Einstell  genauigkeit nicht zu verringern.  



  Gegenstand der     Erfindung    ist ein Basis  entfernungsmesser für photographische Ka  meras, der sich dadurch auszeichnet, dass un  abhängig vom Strahlengang des Entfernungs  messers zwischen den beiden Spiegeln dessel  ben ein Sucher angeordnet ist, dessen Strah  lengang den Strahlengang des Entfernungs  messers schneidet.  



  In der Zeichnung ist. der Erfindungs  gegenstand in einem Ausführungsbeispiel, in       Fig.    1 in einem Vertikalschnitt und in     Fig.    2  im Grundriss veranschaulicht, wobei dieselbe  auf einer Filmkamera angeordnet ist.  



  Der Entfernungsmesser besteht aus einem  Gehäuse 1, in welchem die beiden Spiegel 2  und<B>3</B> angeordnet sind. Der halbdurchlässige  Spiegel 2 wird durch einen Stellknopf 4 he-    tätigt. Zwischen den beiden Spiegeln 2 und  3 ist ,der Bildsucher 5 angeordnet. Der Strah  lengang desselben schneidet. den Strahlen  gang des Entfernungsmessers und     wird    ge  genüber den beiden Spiegeln 2 und 3 des  Entfernungsmessers. durch Blenden 6 und 7,  welche Aussparungen besitzen, die den  Strahlengang des Entfernungsmessers frei  geben, begrenzt.



  Basic rangefinder for photographic cameras. The invention relates to a basic rangefinder for photographic cameras.



  For the viewfinder in photographic cameras, an image-reducing effect is sought in order to be able to see the field of view well, on the other hand, in the rangefinder, the effect is disregarded in order not to reduce the setting accuracy.



  The invention relates to a basic rangefinder for photographic cameras, which is characterized in that, regardless of the beam path of the rangefinder, a viewfinder is arranged between the two mirrors, whose beam path intersects the beam path of the range finder.



  In the drawing is. the subject of the invention in one embodiment, illustrated in Fig. 1 in a vertical section and in Fig. 2 in plan, the same being arranged on a film camera.



  The range finder consists of a housing 1 in which the two mirrors 2 and 3 are arranged. The semi-permeable mirror 2 is actuated by an adjusting button 4. The viewfinder 5 is arranged between the two mirrors 2 and 3. Its beam path intersects. the beam path of the rangefinder and is ge compared to the two mirrors 2 and 3 of the rangefinder. limited by diaphragms 6 and 7, which have recesses that release the beam path of the rangefinder.
