 ten weggebrochen gezeichnet sind, um die Einzelheiten der   erfindungsgemäss   ausgebildeten Schlitzverschlussblende anschaulicher darstellen zu können. 



   In der Zeichnung sind mit 1 und 2 die beiden Teile einer Filmführungsbahn bezeichnet. Der Teil 1 der Filmführungsbahn dient zur Führung des im Querschnitt als Winkelstück ausgebildeten   Spiegelträgers   3, dessen senkrecht verlaufender Schenkel das Bildfenster 4 aufweist. Geführt in dem Teil 1 der Filmführungsbahn ist weiter die Platinenplatte 5, deren dem Beschauer zugewandte Vorderfläche 5'die vom Beschauer abgewandte Begrenzungsfläche des senkrechten Schenkels des Spiegelträgers 3 bei vereinigten Teilen 1 und 2 berührt. Die Spiegel sind strichpunktiert bei 25,26 angedeutet. Zur Verdeutlichung ist der Spiegelträger 3 über den Bereich, innerhalb dessen er schwingend angeordnet ist, aus seiner Führung herausgezogen gezeichnet. 



   In einem Ausschnitt 6 der Platinenplatte 5 ist der Schieber 7   geführt.   Dieser Schieber weist zwei schräge Schlitze 8 und 9 mit zueinander entgegengesetzter Neigung auf. Der senkrechte Schenkel des   Spiegelträgers   3 trägt einen stiftförmigen Vorsprung 10, der im zusammengebauten Zustand der Vorrichtung seine Aufnahme in dem Schlitz 8 des Platinenschiebers 7 findet.

 th are drawn broken away in order to show the details of the inventive focal plane shutter more clearly.



   In the drawing, 1 and 2 denote the two parts of a film guide track. The part 1 of the film guideway serves to guide the mirror carrier 3, which is designed as an angle piece in cross section and whose vertically extending leg has the image window 4. Also guided in part 1 of the film guide track is the circuit board 5 whose front surface 5 ′ facing the viewer touches the boundary surface of the vertical leg of the mirror carrier 3 facing away from the viewer when parts 1 and 2 are combined. The mirrors are indicated by dash-dotted lines at 25.26. For the sake of clarity, the mirror carrier 3 is drawn out of its guide over the area within which it is arranged to oscillate.



   The slide 7 is guided in a cutout 6 of the circuit board 5. This slide has two inclined slots 8 and 9 with mutually opposite inclinations. The vertical leg of the mirror support 3 carries a pin-shaped projection 10 which, in the assembled state of the device, is received in the slot 8 of the sinker slide 7.

Claims

<Desc / Clms Page number 3> The carrier (3) is followed by a shutter that vibrates synchronously with this carrier and consists of two plates (7, 12) which are adjustable in relation to each other and symmetrically to the optical axis of the camera lens and thus releasing a light passage of variable cross-section.

2. SLR camera according to claim 1, characterized in that the shutter is made of EMI3.1 There are boards, the first onen snow part (7) and this slide in the direction of movement of the carrier (3) leading, perpendicular to this adjustable plate plate (5), while the second plate (J2) is designed as a slide member also movable in the direction of movement of the mirror support , pin-like projections (10,13) on EMI3.2 (transverse and oppositely inclined slots (8, 9) of the circuit board slide (7) engage and the two circuit board sliders (7, 12) overlap in the one limit position of the circuit board plate (5), closing the light passage cross-section of the shutter screen, while in the change the position of the circuit board (5)

release a light passage cross-section which corresponds in size to the position of the recess (4) in the carrier (3).

3. SLR camera according to claims 1 and 2, characterized in that the circuit board (20) of the mirror support (3) abut on one, the second circuit board (12) on the other boundary surface of the circuit board (5).

4. SLR camera according to one of claims l to 3, characterized in that the circuit board of the mirror carrier (3) and the Platinenschiebcr (7,12) are arranged between the parts (l, 2) of a multi-part film guide track.
