Description
Bei Reflexkameras muß der Spiegel gegen die Beobachtungsmattscheibe nach dem Zusammenbau der Kamera nachträglich justiert werden, da schon ganz geringe Fehler bei der Herstellung die Spiegellage und somit das Beobachtungsmattscheibenbild beeinflussen. With reflex cameras, the mirror must be against the observation screen after assembly the camera can be adjusted afterwards, as there are very minor errors in influence the mirror position and thus the observation target image during manufacture.
Bisher sind bei diesen Kameras sowohl die Mattscheibe als auch die Spiegel gegeneinander einstellbar angebracht worden. Durch die doppelte Einstellvorrichtung ist es schwer, das Spiegelbild auf den richtigen Platz gegenüber der Mattscheibe zu bringen, da man mit der einen Einstellung die andere wieder verderben kann. Um diese doppelte Einstellung zu vermeiden, ist nach der Erfindung der Spiegel innerhalb einer Spiegelklappe an drei Punkten vertikal verstellbar angebracht. Hierdurch ist es möglich, den Spiegel parallelSo far, both the focusing screen and the mirrors are against each other in these cameras adjustable. The double adjustment device makes it difficult to to bring the reflection in the right place across from the screen, as you are with one attitude can spoil the other. To this double attitude According to the invention, the mirror within a mirror flap is to be avoided at three Vertically adjustable points. This makes it possible to keep the mirror parallel
ao zu verschieben sowie auch seine Neigung gegenüber der Mattscheibe zu ändern. Ein weiterer Vorteil besteht darin, daß die Mattscheibe fest eingebaut werden kann, und ein besonderer Rahmen nicht erforderlich ist.ao to move as well as to change its inclination towards the screen. Another The advantage is that the ground glass can be installed permanently, and a special one Frame is not required.
Abb. ι zeigt den Gegenstand der Erfindung im Schnitt, während Abb. 2 den Grundriß darstellt. An einer Spiegelklappe a, die durch Streben b gehalten wird, befindet sich ein durch Schrauben c verstellbarer Spiegelträger d mit einem Spiegele. Die Schraubenc, die an drei Punkten des Spiegels angreifen, sind mit Gegenmuttern/ versehen, um die gewünschte Justierung des Spiegels festzuhalten.Fig. Ι shows the subject of the invention in section, while Fig. 2 shows the plan. On a mirror flap a, which is held by struts b , there is a mirror support d adjustable by screws c with a mirror. The screws c, which engage at three points on the mirror, are provided with lock nuts / to hold the desired adjustment of the mirror.
