Description
<Desc/Clms Page number 1>
Photographische Kamera mit eingebautem photoelektrischen Belichtungsmesser.
Gegenstand der Erfindung ist ein mit einer Kamera verbundener photoelektrischer Belichtungmesser, dessen photoelektrische Zelle zweckmässig an der Vorderwand der Kamera angebracht ist. Um die empfindliche Zelle einerseits gegen Beschädigung zu schützen und anderseits den Lichteinfall entsprechend zu begrenzen, wird erfindungsgemäss die Photozelle durch Lichtschutzkappen, welche einen Kanal bilden, umgeben und durch diesen verschlossen.
Durch einen solchen Lichtschacht soll es ermöglicht werden, dass nur das von der Aufnahmeszene kommende Licht zur lichtempfindlichen Zelle gelangt, während das von oben kommende Licht durch die obere Wand des Lichtschachtes abgehalten wird.
In der Zeichnung ist der Erfindungsgegenstand beispielsweise in den Fig. 1-3 dargestellt. 1 ist die Kamera, 2 die photoelektrische Zelle des in die Kamera eingebauten photoelektrischen Belichtungsmessers. 3, 4, 5 und 6 sind die den Lichtkanal bildenden Abschlusskappenfür die Photozelle. Diese können unter dem Einfluss von Federn in die Gebrauchsstellung gebracht werden. Bei Nichtgebrauch der Kamera kommen die Wände des Lichtschutzschachtes auf die Photozelle zu liegen.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Photographic camera with built-in photoelectric light meter.
The invention relates to a photoelectric exposure meter connected to a camera, the photoelectric cell of which is expediently attached to the front wall of the camera. In order to protect the sensitive cell on the one hand against damage and on the other hand to limit the incidence of light accordingly, according to the invention the photocell is surrounded by light protection caps which form a channel and closed by this.
Such a light shaft should make it possible that only the light coming from the recording scene reaches the light-sensitive cell, while the light coming from above is kept away by the upper wall of the light shaft.
In the drawing, the subject matter of the invention is shown, for example, in FIGS. 1-3. 1 is the camera, 2 is the photoelectric cell of the photoelectric exposure meter built into the camera. 3, 4, 5 and 6 are the end caps for the photocell that form the light channel. These can be brought into the position of use under the influence of springs. When the camera is not in use, the walls of the light protection shaft come to rest on the photocell.
