Description

Den Gegenstand vorliegender Erfindung bildet eine Einrichtung, welche ein leichtes Justieren des in einem Basisentfernungsmesser mit zwei Spiegeln fest angeordneten Spiegels gestattet. Diese Arbeit war insbesondere bei Entfernungsmessern, welche -im Gehäuse photographischer Apparate eingebaut waren, mit großen Schwierigkeiten verbunden, da der Spiegel dort schwer zugäng- »o Hch war..The subject of the present invention is a device which is lightweight Adjusting the fixed in a base rangefinder with two mirrors Mirror permitted. This work was particularly important with rangefinders, which -im Housings of photographic apparatus were built in, associated with great difficulties, since the mirror was difficult to access there- »Oh dear ..

Diesen Nachteil behebt die Erfindung dadurch, daß man die Lagerung der Spiegelfassung kugelförmig ausbildet. Dadurch wird eine leichte Justierung des im Ent- «5 fernmtgsmessef vorgesehenen Spiegels mittels der hierzu vorgesehenen Schrauben ermöglicht. The invention overcomes this disadvantage by changing the mounting of the mirror mount spherical. This enables easy adjustment of the «5 Fernmtgsmessef provided mirror means the screws provided for this purpose.

In der Zeichnung ist die Erfindung inIn the drawing, the invention is shown in

einem Ausführungsbeispiel in Abb. 1 im Aufriß, in Abb. 2 im Grundriß dargestellt, bei dem der Entfernungsmesser im Gehäuse der photographischen Kamera eingebaut ist.an embodiment in Fig. 1 in elevation, shown in Fig. 2 in plan where the rangefinder is built into the housing of the photographic camera.

ι ist die Spiegelfassung, welche mit einer kugelförmigen Fläche 2 versehen ist, die in »5 einer gleichgeformten kugligen Fläche des Kameragehäuses gleitet. 3 ist der feste Spiegel des Entfernungsmessers, welcher beim Gebrauch desselben unbeweglich bleibt. Durch die Schrauben 4 und 5 wird der Pyramidalfehler korrigiert und vermittels der Schrauben 6 und 7 der Höhenfehler. Die Korrektion der Entfernung erfolgt durch axiale Drehung der Spiegelfassung in horizontaler Richtung.ι is the mirror mount, which is provided with a spherical surface 2, which is shown in »5 slides on a spherical surface of the same shape on the camera housing. 3 is the fixed one The rangefinder's mirror, which remains immobile when it is used. The pyramidal error is corrected by the screws 4 and 5 and by means of the Screws 6 and 7 of the height error. The distance is corrected by rotating the mirror mount axially horizontally Direction.

Um einen Anhalt darüber zu haben, ob der Film in der Kamera vorschriftsmäßig abläuft, ist die Achse der Filmspule durch die Achse des kugelförmigen Lagers der Spiegelfassung geführt und mit einer Scheibe verbunden die sich beim Filmtransport mit dreht. Diese Scheibe dient gleichzeitig als Deckscheibe für das kugelförmige Lager und für die Justierschrauben, der Spiegelfassung.In order to have an indication of whether the film is running properly in the camera, is the axis of the film spool through the axis of the spherical bearing of the mirror mount guided and connected to a disk that rotates with the film transport. This disc also serves as a Cover disk for the spherical bearing and for the adjusting screws, the mirror mount.
