Abstract
A cocking mechanism for electric focal plane shutters arranged so that, in order to simplify the cocking mechanism, while a shutter opening controlling armature lever is brought to the cocked position from the uncocked position, a shutter closing controlling armature lever may be brought to the cocked position from the uncocked position by the shutter opening controlling armature lever and, when the shutter opening controlling lever is locked in the cocked position, the shutter closing controlling armature lever may be held in the cocked position.
