    摘要： The invention relates to a device for controlling a central shutter, in which a plurality of shutter blades (3) are pivotally mounted at a pivot arm (4) on a circular ring-shaped blade carrier (1), and in which as an actuating device for the pivoting movement of the shutter blades (3) an annular cam disc (5) is mounted on the blade carrier (1) concentrically with respect to the shutter aperture (2) and so as to be continuously rotatable in one direction. The rotation of the cam disc (5) can be blocked by mechanical engagement in a cam trough (8) in front of an actuating edge (6) of a cam. The device is characterised in that a lifting magnet push rod (9, 10) movable perpendicularly with respect to the plane of the cam disc (5) is provided for mechanical blocking.
