Im Bereich der Stellkurve 12 ist der Stellarm 16 so wird zunächst die Marke 32 an Hand der Skala 33 des Stellhebels 17 angeordnet, der mittels einer Kupp- für die Belichtungszeiten eingestellt.

Im Hubbereich der Schließtaste 19 ist nach rückwärts gezogen, wobei der Raststift 14 außer der Spannhebel 20 angeordnet, dessen Spannfeder 21 io Eingriff mit den Rastkerben 15 gelangt. Dabei schließt am Aufzugshebel 22 der Kamera eingehängt ist. Der der Blendenvorwählring 8 den Schalter 29 und drückt Spannhebel 25 hält den Aufzugshebel 22 entgegen die Schließtaste 19 gegen den Spannhebel 20, der der ebenfalls am Aufzugshebel 22 angehängten An- sich entgegen der Spannfeder 21 entgegen dem Uhrtriebsfeder 23 für den Schwenkspiegel 24.

After that, the Lungsfeder 18 with the closing button 19 non-positive, aperture pre-selection 8 in the direction of the optical axis connected is. In the stroke area of the lock button 19 is pulled backwards, the locking pin 14 except the tensioning lever 20 is arranged, the tensioning spring 21 of which engages the locking notches 15. It closes is suspended on the elevator lever 22 of the camera. The aperture preselection ring 8 presses the switch 29 and Tensioning lever 25 holds the winding lever 22 against the closing button 19 against the tensioning lever 20, the that is also attached to the winding lever 22 against the tension spring 21 against the clock drive spring 23 for the oscillating mirror 24. The tension indicator turns. The clutch spring 18 pulls the lever 25 can be actuated by the camera release 26. 15 adjusting lever 17 until the adjusting arm 16
Der Schwenkspiegel 24 trägt die photoelektrische gegen die Stellkurve 12 legt. Infolgedessen kann die Schicht 27, die in Reihe mit dem Meßwerk 28 und Stellfeder 6 die Blendensektoren 3 auf den vorgedem Schalter 29 an der Batterie 30 liegt. Der Zeiger wählten Blendenwert schließen, so daß eine der vor-31 des Meßwerkes 28 schwingt gegenüber einer gewählten Blende entsprechende Lichtstärke die Marke 32, die nach Maßgabe weiterer Belichtungs- 20 photoelektrische Schicht 27 erreicht. Der Blendenfaktoren, beispielsweise einer Skala 33 mit Werten vorwählring 8 wird nun so lange gedreht, bis der Zeifür Belichtungszeiten, einstellbar ist. Der Schalter 29 ger 31 der Marke 32 gegenübersteht. Dann wird der liegt zusammen mit der Schließtaste 19 im axialen Blendenvorwählring 8 losgelassen und kann infolge Hubbereich des Blendenvorwählringes 8. seiner Rastfedern 13 und der Spannfeder 21 wiederThe swivel mirror 24 carries the photoelectric which places against the adjusting cam 12. As a result, the Layer 27, in series with the measuring mechanism 28 and adjusting spring 6, the diaphragm sectors 3 on the vorgedem Switch 29 is on the battery 30. The pointer selected the aperture value close so that one of the before-31 of the measuring mechanism 28 oscillates with respect to a selected aperture corresponding light intensity Mark 32, which reaches photoelectric layer 27 according to further exposure 20. The aperture factors, for example a scale 33 with values preselection ring 8 is now rotated until the Zeifür Exposure times, is adjustable. The switch 29 ger 31 of the mark 32 is opposite. Then the is released together with the closing button 19 in the axial aperture preselection ring 8 and can as a result Stroke range of the aperture preselection ring 8, its detent springs 13 and the tension spring 21 again
Die Wirkungsweise der Vorrichtung ist folgende: 25 mit seinem Raststift 14 in eine der Rastkerben 15The method of operation of the device is as follows: 25 with its locking pin 14 into one of the locking notches 15

Gleichzeitig ist die Aufnähmestrahlengang schwenkt und die Spannfeder Spannfeder 21 aufgezogen und dabei der Spannhebel 21 sich entspannt. Deshalb kann die Stellfeder 6 den 20 im Uhrzeigersinn gedreht worden, welcher über Stellhebel 17 zurückführen, bis der Stellarm 16 an die Schließtaste 19 den Stellhebel 17 nach vorn der Stellkurve 12 anschlägt. Dann ist die der herrdrückt. Dabei hebt sich der Stellarm 16 von der 35 sehenden Helligkeit entsprechende Blendenöffnung Stellkurve 12 ab, und der Stellhebel 17 dreht den ■ eingestellt, und der eigentliche Belichtungsvorgang Winkelhebel 5 entgegen der Stellfeder 6, also entgegen kann sich anschließen. ,that the film is expediently transported and the pressure when the camera release button 26 is pressed down Finally tensioned and the pivoting mirror 24 in the locking lever 25, the elevator lever 22 free, wherein Clockwise counter to the drive spring 23 in Su- 30, the drive spring 23 removes the swivel mirror 24 from the representation is panned. At the same time the pick-up beam path pivots and the tension spring Tension spring 21 is pulled up and the tension lever 21 is relaxed. Therefore, the adjusting spring 6 can the 20 has been turned clockwise, which lead back via adjusting lever 17 until the adjusting arm 16 is on the closing button 19 strikes the adjusting lever 17 towards the front of the adjusting cam 12. Then the one who dominates. The actuating arm 16 is lifted from the aperture corresponding to the brightness seen Adjustment curve 12 from, and the adjusting lever 17 rotates the ■ set, and the actual exposure process Angle lever 5 against the adjusting spring 6, so against can connect. ,
