Description
Die Erfindung bezieht sich auf eine automatische Blendensteuervorrichtung für eine einäugige Spiegelreflexkamera, in welcher beim Fotografieren mit Belichtungsautomatik ein mit der Blende betriebsmäßig gekuppelter Hebel automatisch eine bestimmte Blendenöffnung einstellen kann.The invention relates to an automatic aperture control device for a single lens reflex camera, in which when photographing with automatic exposure an operationally coupled with the aperture Lever can automatically set a specific aperture.
Bei bekannten einäugigen Spiegelreflexkameras mit Belichtungsautomatik, wie sie etwa aus der japanischen Patentschrift 15 727/1964 bekannt sind, liefert das Niederdrücken eines Verschlußauslöseknopfes die Kraft, die zum Verschieben einer verzahnten Blendensperrplatte in eine vom Ausschlagwinkel des Zeigers eines Belichtungsmessers abhängige Stellung erforderlich ist. Wenn der Verschlußauslöseknopf weiter niedergedrückt wird, wird ein mit einer Blende betriebsmäßig gekuppeltes Teil mit der verzahnten Blendensperrplatte in Eingriff gebracht, und anschließend wird der Spiegel hochgeschwenkt und der Verschlußmechanismus betätigt. Die herkömmliche Blendensteuervorrichtung hat deshalb einen sehr kompliziertenIn known single-lens reflex cameras with automatic exposure, such as those from the Japanese Patent 15 727/1964 are known, the depression of a shutter release button provides the Force required to move a toothed diaphragm locking plate into one of the deflection angle of the pointer a light meter dependent position is required. When the shutter release button continues is depressed, a member operatively coupled to a diaphragm becomes with the interlocking diaphragm lock plate is brought into engagement, and then the mirror is pivoted up and the locking mechanism actuated. The conventional diaphragm control device therefore has a very complicated one
Aufbau, und die Kraft zum Niederdrücken des Verschlußauslöseknopfes und der Weg desselben sind bei einer einäugigen Spiegelreflexkamera mit einem nach der Zeigerabtastmethode arbeitenden Belichtungssteuei system sehr groß.Structure, and the force to depress the shutter release button and the way of the same are with a single-lens reflex camera with one after the exposure control system working with the pointer scanning method is very large.
ίο Der Erfindung liegt die Aufgabe zugrunde, eine einäugige Spiegelreflexkamera mit Belichtungsautomatik zu schaffen, in welcher die Bewegung bzw. der Hub eines Verschlußauslöseknopfes ebenso kurz oder kürzer ist wie bei einer einäugigen Spiegelreflexkameraίο The invention is based on the object of a one-eyed To create single-lens reflex camera with automatic exposure, in which the movement or the stroke of a shutter release button is just as short or shorter as that of a single-lens reflex camera

Diese Aufgabe wird durch die im Anspruch 1 gekennzeichneten Mittel gelöst.This object is achieved by the means characterized in claim 1.
Die Erfindung schafft also eine Vorrichtung zumThe invention thus creates a device for

Dadurch kann der Hub bzw. die Bewegung des Verschlußauslöseteils verringert und der Aufbau einer Blendensteuervorrichtung beträchtlich vereinfacht werden. iS aperture control elements actuated. When the start lever is actuated, a toothed diaphragm locking plate is moved into a position that corresponds to the angular position of the pointer of a light meter in order to control the angle of rotation of a ratchet lever, which in turn controls the angle of rotation of an iris control lever which is operatively coupled to a pin that is operatively coupled to the lens diaphragm is engaged, whereby the optimal aperture is set. As a result, the stroke or the movement of the shutter release part can be reduced and the structure of a diaphragm control device can be considerably simplified.
Ein Ausführungsbeispiel der Erfindung ist in der Figur dargestellt.An embodiment of the invention is shown in the figure.
Diese Figur zeigt eine auseinandergezogene perspektivische Ansicht — von der Unterseite einer Kamera her gesehen — einer automatischen Blendensteuervorrichtung nach der Erfindung, deren Einzelteile sich in gespanntem Zustand befinden. Die Kamera ist dabei auf Betrieb mit automatischer Belichtung eingestellt. This figure shows an exploded perspective view - from the bottom of a camera seen here - an automatic diaphragm control device according to the invention, its individual parts are in a tensioned state. The camera is set to operate with automatic exposure.
Ein Auslösehebel 1, der mit einem nicht dargestellten Verschlußauslöseknopf gekuppelt ist, wird in der durch den Pfeil A angezeigten Richtung verschoben, wenn der Auslöseknopf niedergedrückt wird. Ein erster Ausrückhebel 3. der mit einem Drehzapfen 5 an der Unterseite eines .Spiegelkastens bzw. -gehäuses 4 drehbar gelagert ist, hat ein mit einem Stift 2 an dem Auslösehebel 1 gekuppeltes Ende und ein mit einem Starthebel 6 in Eingriff befindliches anderes Ende. Der Starthebel 6 ist mit einem Drehzapfen 7 an einer Seitenwand des Spiegelkastens 4 drehbar gelagert und ist in geladenem bzw. gespanntem Zustand dargestellt. Ein Spannhebel 8, der an der Unterseite des Spiegelkastens 4 mit einem Drehzapfen 9 drehbar gelagert ist, hat eine Feder 10, die zwischen den Starthebel 6 und den Spannhebel 8 eingehängt ist, und eine weitere Feder 11, die zwischen den Spannhebel 8 und ein feststehendes Teil der Kamera eingehängt ist, so daß der Starthebel 8 normalerweise im Uhrzeigersinn vorgespannt ist. Wenn der Film weitertransportiert wird, wird der Spannhebel 8 in der durch den Pfeil B angezeigten Richtung gedreht.A release lever 1, which is coupled to an unillustrated shutter release button, is displaced in the direction indicated by arrow A when the release button is depressed. A first release lever 3, which is rotatably mounted with a pivot 5 on the underside of a .Spiegelkastens or -gehäuses 4, has one end coupled to a pin 2 on the release lever 1 and another end engaged with a starter lever 6. The start lever 6 is rotatably supported by a pivot 7 on a side wall of the mirror box 4 and is shown in the loaded or tensioned state. A tensioning lever 8, which is rotatably mounted on the underside of the mirror box 4 with a pivot 9, has a spring 10 which is suspended between the starting lever 6 and the tensioning lever 8, and another spring 11, which is between the tensioning lever 8 and a fixed Part of the camera is hooked so that the start lever 8 is normally biased clockwise. When the film is advanced, the tension lever 8 is rotated in the direction indicated by arrow B.
