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.
