Description
Gegenstand der Erfindung ist eine weitereThe subject of the invention is another
Ausbildung und Verbesserung der nach Patent 514 946 geschützten Vorrichtung zur Einstellung der Belichtungszeit an photographischen Apparaten. Beim Hauptpatent ist direkt an der Zeiteinstellskala ein Graukeil (Verdunklüngsstreifen) vorgesehen, welcher innen einen Bildsucher trägt und vorn zum Drehen mit einer eine Öffnung aufweisenden, geriffelten Schabe versehen ist.Training and improvement of the device protected by patent 514 946 for Setting the exposure time on photographic equipment. The main patent is A gray wedge (darkening strip) is provided directly on the time setting scale, which inside carries a viewfinder and front to rotate with an opening having, corrugated cockroach is provided.
Bei dieser Anordnung besteht jedoch der Nachteil, daß der Graukeil derart ausgebildet ist, daß derselbe bei Einstellung die das Bild wiedergebende Linse vollkommen verdunkelt, wodurch insbesondere bei Aufnahmen von Hand aus nicht mehr festgestellt werden kann, ob sich das gewünschte Bild noch im Sucher befindet.With this arrangement, however, there is the disadvantage that the gray wedge is designed in this way is that the same, when adjusted, completely darkens the lens reproducing the image, This means that it is no longer possible to determine whether the desired image is still in the image, especially when taking pictures by hand Viewfinder is located.
Durch die vorliegende Erfindung wird dieser Nachteil beseitigt. Die Neuerung besteht darin, daß der Graukeil die das Bild wiedergebende Linse bei Einstellung nur zum Teil verdunkelt. Zu diesem Zweck erhält der Graukeil nur die halbe Breite der das Bild wiedergebenden Linse.The present invention overcomes this disadvantage. The innovation is there in that the gray wedge only partially blocks the lens reproducing the image when it is adjusted darkened. For this purpose, the gray wedge is only given half the width of the image reproducing lens.
Die Vorteile dieser Erfindung bestehen darin, daß bei Aufnahmen auch nach der Zeiteinstellung, also nach der Verdunklung des Bildes, dieses noch in der Sucherlinse zu sehen ist, so daß Fehlaufnahmen mit Sicherheit vermieden werden.The advantages of this invention are that when shooting even after Time setting, i.e. after the image has been darkened, it is still in the viewfinder lens can be seen, so that incorrect recordings can be avoided with certainty.

An der Zeiteinstellskala b ist wiederum der Graukeil c angeordnet, welcher innen den Sucher g, k, i trägt und vorn zum Drehen eine geriffelte, mit einer Öffnung d versehene Scheiben erhält. Hierbei ist der Graukeile so ausgebildet, daß derselbe die das Bild wiedergebende Linse ί nur bis zur Hälfte verdunkelt, so daß auch nach der Zeiteinstellung das Bild im Sucher zu sehen ist.The gray wedge c is again arranged on the time setting scale b , which carries the viewfinder g, k, i on the inside and is provided with a corrugated disk with an opening d at the front for turning. The gray wedge is designed in such a way that it only darkens the lens ί reproducing the image by half, so that the image can be seen in the viewfinder even after the time has been set.
