ABSTRACT:
The shutter mechanism includes a blade pivotally mounted intermediate its ends. Nearer one end of the blade is an opening through which the subject is viewed when focusing the camera and through which the picture itself is later taken as the blade swings from one side of the optical axis to the other. Nearer the other end of the blade is a permanent magnet which is cooperable with three electromagnets. Appropriate energization of the electromagnets effects the various blade movements.
