Die Erfindung bezieht sich auf einen Entfernungsmesser, bestehend aus einem Objektiv und einer relativ dazu in Richtung der optischen Achse des Objektivs verstellbar angeordneten Einstellscheibe. Derartige Entfernungsmesser haben vorzugsweise als Sucherentfernungsmesser für photographische und Mnematographische Aufnahmekameras Verwendung gefunden. Als Einstellplatte diente bisher regelmäßig eine Anordnung von zwei längs einer Trennkante zusammenstoßenden Glaskeilen mit entgegengesetzter ablenkender Wirkung. Der Benutzer hatte den Abstand zwischen Objektiv und Einstellplatte so lange zu verändern, bis die Konturen des einzustellenden Gegenstandes oberhalb der Trennlinie keine seitliche Versetzung gegenüber den Konturen unterhalb der Trennlinie zeigten. Diese Entfernungsmesser sind wie alle Schnittbildentfernungsmesser anwendbar, solange eine zur Einstellung geeignete Kontur, also eine solche genügender Schärfe vorhanden ist, die die Trennlinie im wesentlichen senkrecht schnei- ao det. In der Praxis führt das Aufsuchen einer derartigen Kontur, was insbesondere bei der Anwendung in kinematographischen Aufnahmekameras stört, zu einer lästigen Zeitverzögerung.The invention relates to a range finder consisting of an objective and a relative to this in the direction of the optical axis of the lens adjustable adjustment disk. Such rangefinder have preferably as a finder rangefinder for photographic and Mnematographic recording cameras found use. Up to now it has been used regularly as an adjustment plate an arrangement of two glass wedges colliding along a separating edge with opposite one another distracting effect. The user had the distance between the lens and the setting plate like this to change for a long time until the contours of the object to be set do not exist above the dividing line showed lateral displacement with respect to the contours below the dividing line. These rangefinders can be used like all cross-sectional rangefinders as long as a contour suitable for setting, that is, there is sufficient sharpness that the dividing line essentially intersects vertically det. In practice, the search for such a contour leads, especially when used in cinematographic recording cameras bothers, leading to an annoying time delay.
Deshalb wurden für photographische Zwecke vielfach die von diesen Nachteilen freien Mischbildentfernungsmesser bevorzugt. Die bekannten Entfernungsmesser dieser letztgenannten Art waren vorgesehen, wenn ein besonderer, von dem Aufnahmeobjektiv unabhängiger, meist mit einem Sucher verbundener Entfernungsmesser vorhanden war. Zum Einbau in einäugige Spiegelreflexkameras waren sie nicht geeignet.Therefore, the mixed image rangefinders free from these disadvantages have been widely used for photographic purposes preferred. The known range finders of this latter type were intended if a special one, independent of the taking lens, usually with a viewfinder connected rangefinder was present. They were for installation in single-lens reflex cameras not suitable.
Durch die im Anspruch gekennzeichnete Erfindung wird erstmals ein Mischbildentfernungsmesser der eingangs genannten Gattung geschaffen, der insbesondere für einäugige Spiegelreflexkameras und für nach dem gleichen Prinzip arbeitende kinematographische Aufnahmekameras geeignet ist.The invention characterized in the claim for the first time provides a mixed image rangefinder of the type mentioned above, which is particularly suitable for single-lens reflex cameras and is suitable for cinematographic recording cameras working on the same principle.

gewählt, daß die beiden Strahlenbüschel 3 und 4 symmetrisch zur optischen Achse 5 verlaufen. Sie durchsetzen die Randpartien der wirksamen Öffnung des Objektivs 6. Ist letzteres auf die Aufnahmeentfernung eingestellt, so decken sich die den Strahlenbüscheln 3 und 4 zugeordneten Halbbilder. Die Beobachtung dieses Mischbildes kann über die Lupe 7 erfolgen.chosen so that the two bundles of rays 3 and 4 extend symmetrically to the optical axis 5. she penetrate the edge portions of the effective opening of the lens 6. Is the latter on the shooting distance is set, the fields assigned to the bundles of rays 3 and 4 coincide. The observation this mixed image can take place via the magnifying glass 7.
