 häuses 16 verbunden. Durch Auf- oder Abbewegen des Stellschiebers 22 wird der Sucher um die horizontale Achse 30 (Fig. 1) verschwenkt, die nahe der vertikalen Welle 14 des Galvanometers an der Stirnwand der Kamera gelagert ist. Der Stellschieber 22 gleitet in einem Schlitz 31a eines Schildes 32, das an der Rückwand 31 der Kamera angebracht und mit zwei Skalen 32 versehen ist, die in Metern und   z. B.   in englischen Fuss, nach Scharfeinstellung der Kamera die Entfernung des Objektes angeben, auf welches der Sucher eingestellt wird, um die Bildparallaxe zu beseitigen. Das Schild ist durch zwei Schrauben 33 an der Kamera und durch die Schraube 34 am Tragriemen festgehalten.

   Eine auf den Sperrbolzen 23 wirkende Flachfeder   37   arretiert den Schieber 22 beim Verschwenken in den einzelnen Stellungen dadurch, dass der Sperrbolzen in entsprechende Ausnehmungen 22a des Schiebers einrastet. Zum Justieren des Suchers dienen zwei Schrauben 24, die den Stellschieber 22 mit der   Ruckleiste   25 des Schiebers verbinden, u. zw. so, dass nach dem Justieren des Suchers auf eine hyperfokale Entfernung die Schrauben 24 festgezogen werden, damit der Stellschieber 22 und die Rückleiste 25 des Schiebers ein Ganzes bilden. Die Marke 36 wird auf dem Stellschieber erst nach   der Justierung angezeichnet. Zugleich   mit dem Verschwenken des Suchers wird auch das Galvanometer so verschwenkt, dass die Leiter eine Parallelbewegung zum Galvanometer ausführen. Das Verkürzen bzw.

   Verlängern derselben erfolgt auf der freien Länge der Leiter zwischen der elastischen Einlage 35 und der Photozelle 10. 



    PATENTANSPRÜCHE :    
1. Photographische oder kinematographische Kamera mit zum Ausgleich der Parallaxe zwischen Sucher und Aufnahmeobjektiv auf der Oberseite des Kameragehäuse schwenkbar gelagerten Fernrohrsucher und Belichtungsmesser, dessen Zeiger im Sucher mit einem Zeiger zum Einstellen von Belichtungsfaktoren zur Deckung gebracht wird, dadurch gekennzeichnet, dass der Fernrohrsucher (16) und das Messinstrument (13) des Belichtungsmessers eine Baueinheit bilden, die auf der Oberseite des Kameragehäuse um eine horizontale, zur optischen Achse des Fernrohrsuchers (16) senkrechte Achse (30) schwenkbar ist, wobei das Messinstrument (13) nahe der Drehachse (30) angeordnet ist.

 housing 16 connected. By moving the adjusting slide 22 up or down, the viewfinder is pivoted about the horizontal axis 30 (FIG. 1), which is mounted on the front wall of the camera near the vertical shaft 14 of the galvanometer. The adjusting slide 22 slides in a slot 31a of a shield 32 which is attached to the rear wall 31 of the camera and is provided with two scales 32, which are in meters and z. B. in English feet, after focusing the camera, specify the distance of the object to which the viewfinder is set to eliminate the image parallax. The shield is held in place by two screws 33 on the camera and by screw 34 on the carrying strap.

   A flat spring 37 acting on the locking pin 23 locks the slide 22 when it is pivoted in the individual positions in that the locking pin engages in corresponding recesses 22a of the slide. To adjust the viewfinder, two screws 24 are used which connect the adjusting slide 22 to the jerk strip 25 of the slide, u. so that after adjusting the viewfinder to a hyperfocal distance, the screws 24 are tightened so that the adjusting slide 22 and the rear strip 25 of the slide form a whole. The mark 36 is only marked on the setting slide after the adjustment. At the same time as the viewfinder is swiveled, the galvanometer is swiveled so that the conductors move parallel to the galvanometer. The shortening or

   Lengthening of the same takes place on the free length of the conductor between the elastic insert 35 and the photocell 10.



    PATENT CLAIMS:
1. A photographic or cinematographic camera with a telescopic viewfinder and exposure meter pivotably mounted on the top of the camera housing to compensate for the parallax between the viewfinder and the taking lens, the pointer of which is brought into congruence in the viewfinder with a pointer for setting exposure factors, characterized in that the telescopic viewfinder (16 ) and the measuring instrument (13) of the exposure meter form a structural unit which can be pivoted on the top of the camera housing about a horizontal axis (30) perpendicular to the optical axis of the telescopic viewfinder (16), the measuring instrument (13) being close to the axis of rotation (30 ) is arranged.

 

Claims (1)

2. Photographische oder kinematographische Kamera nach Anspruch 1, dadurch gekennzeichnet, dass zum Verschwenken der Baueinheit (13, 16) ein Hebelsystem (25, 26, 27) vorgesehen ist, und zur Betätigung des Hebelsystems ein Stellschieber (22) längs einer die Entfernung des eingestellten Objektes angebenden Skala (32) verschiebbar und in der jeweiligen Einstellung durch einen federnden Sperrbolzen (23, 37) arretierbar ist, der in entsprechende Ausnehmungen (22a) des Schiebers (22) einrastet. 2. Photographic or cinematographic camera according to claim 1, characterized in that a lever system (25, 26, 27) is provided for pivoting the structural unit (13, 16), and for actuating the lever system, an adjusting slide (22) along a distance of the The set object indicating scale (32) is displaceable and can be locked in the respective setting by a resilient locking pin (23, 37) which engages in corresponding recesses (22a) of the slide (22).
