PHOTOGRAPHIC CAMERA WITH COUPLED EXPOSURE METER Filed Aug. 21, 1959 5 Sheets-Sheet 1 May 15, 1962 E. SAUER 3,034,411
The invention relates to photographic cameras and particularly to single lens reflex cameras.
The photographic camera of the invention is provided with a built-in photoelectric exposure meter having an electrical measuring instrument of which the deiiection of its pointer is influenced by an element, for instance, a resistance in the photo cell circuit or a diaphragm placed in front of the photo cell, which element is con nected'with one of the two exposure adjusting members, for instance the diaphragm adjusting device of the photographic objective, while the nal adjustment of the camera is accomplished by a coupling connection of the other exposure adjusting member, for instance the shutter speed adjusting member, with the measuring instrument.
It is an object of the invention to arrange the exposure adjusting members in a camera of the above mentioned type and also the exposure meter on or at the upper wall =of the camera casing and to make these members and the meter readable from above. Furthemore, the invention provides that one of the two exposure adjusting members, preferably the shutter speed adjusting member, is connected by a coupling element which extends along the top wall of the camera casing with the measuring instrument `of the exposure meter.
The coupling element may consist of any substantially straight and continuous transmission member such as a link, a push rod, a rack bar or combinations of these elements, but preferably a cable transmission is used and when such a cable transmission is used, it is possibleto employ a deiinite length of a piece of cable with its ends attached to the members to be connected with each other by means of the interposition or a power source, such as a spring in a spring casing, or such a power-source may be eliminated entirely by employing an endless cable which is led over guide rollers.
