Abstract
A camera shutter device including an optical opening and an electromagnetic drive mounted fixedly relative to the opening, and having a linearly guided, movable part which is fixedly connected to a first shutter blade to form one unit. The unit is connected to a drive end of a two-armed lever which is rotatable about an axis of rotation. A counterweight is provided at an output end of the lever. A second weight force acting on the counterweight causes a second torque about the axis of rotation of the lever, which counteracts a first torque which is caused by a first weight force acting on the unit.
