Description
<Desc/Clms Page number 1>
Photographische Kamera mit eingebautem photoelektrischen Belichtungsmesser.
Die Erfindung betrifft einerseits die Anordnung eines photoelektrischen Belichtungsmessers in der Sucherkammer und anderseits die Kupplung desselben mit der Zeit-und Blendeneinstellung des photographischen Verschlusses des Aufnahmeobjektives.
Erfindungsgemäss erfolgt die Anordnung der Photozelle beiderseits des Sucherobjektivs, u. zw. an der Vorderwand der Kamera. Oberhalb des Sucherobjektivs befindet sich die Skala für die Scheinergrade. Die Blenden-und Zeiteinstellung erfolgt durch Hebel von oben her. Zweckmässig sind hiebei auch die Skalen für die Zeiteinstellung sowie für die Blendeneinstellung auf der oberen Seite der Kamera angeordnet und von oben her ablesbar. Innerhalb der Kamera befindet sich das Messinstrument mit einem Zeiger, welcher auf eine feste Marke einspielen muss.
In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel in den Fig. 1 bis 3 an einer Kamera dargestellt, bei der sich oberhalb der Aufnahmekammer eine Spiegelsucherkammer befindetr Fig. 4 stellt ein Schaltschema des photoelektrischen Belichtungsmessers dar. 1 und 2 sind die photoelektrischen Zellen, welche vorliegenden Falles beiderseits des Objektives der Sucherkammer angeordnet sind. 3 ist die Einstellskala für die Scheinergrade. Diese befindet sich oberhalb des Sucherobjektivs. Die Einstellung der Scheinergrade erfolgt mittels eines Knopfes 4 über den Kontakt 5 auf dem Widerstand 6. 7 ist die Skala für die Belichtungszeiteinstellung und 8 für die Blendeneinstellung. Die Einstellung der Belichtungszeiten erfolgt durch einen Hebel 9 und die Blendeneinstellung durch einen Hebel 10.
Der Einstellhebel 9 reguliert den Widerstand 11 durch einen Kontakt 12, während mit dem Blendeneinstellhebel M der gesamte Widerstand 11 verdreht wird. Den Instrumentenzeiger 13 des in der Kamera befindlichen Messinstrumentes lässt man auf eine feste Marke 14 einspielen. Die abgelesenen Daten werden sodann am Objektivverschluss und der Blende eingestellt.

Photographic camera with built-in photoelectric light meter.
The invention relates, on the one hand, to the arrangement of a photoelectric exposure meter in the viewfinder chamber and, on the other hand, to the coupling of the same with the time and aperture setting of the photographic shutter of the taking lens.
According to the invention, the arrangement of the photocell takes place on both sides of the viewfinder lens, u. between the front wall of the camera. Above the viewfinder lens is the scale for the apparent degrees. The aperture and time are set using levers from above. The scales for the time setting and for the aperture setting are expediently arranged on the upper side of the camera and can be read from above. Inside the camera there is the measuring instrument with a pointer, which has to read a fixed mark.
In the drawing, the invention is shown in an exemplary embodiment in FIGS. 1 to 3 on a camera in which a mirror finder chamber is located above the receiving chamber. FIG. 4 shows a circuit diagram of the photoelectric exposure meter. 1 and 2 are the photoelectric cells which The present case are arranged on both sides of the objective of the viewfinder chamber. 3 is the setting scale for the apparent degrees. This is located above the viewfinder lens. The shimmer degrees are set by means of a button 4 via the contact 5 on the resistor 6. 7 is the scale for the exposure time setting and 8 for the aperture setting. The exposure times are set using a lever 9 and the aperture setting is made using a lever 10.
The adjustment lever 9 regulates the resistor 11 through a contact 12, while the entire resistor 11 is rotated with the diaphragm adjustment lever M. The instrument pointer 13 of the measuring instrument located in the camera can be imported onto a fixed mark 14. The data read is then set on the lens shutter and the diaphragm.
PATENT CLAIMS:
1. Photographic camera with built-in exposure meter, characterized in that the photocells (1 and 2) are arranged on both sides of the recording or viewfinder lens on the front wall of the camera.
