摘要： When a hold member rotates on a shaft counterclockwise in the set operation, pressing parts of a pressing member which is fitted on top end of the hold member press pressed parts of iron piece members to rotate a lock-releasing member for a first blade and a lock-releasing member for a rear blade so that the iron piece members are made to come into contact with iron-core members of electromagnets, while an engagement pin presses an arm of a connection spring to rotate a restraining member clockwise so that a restraining part of the restraining member moves into the trajectory of the movement of a restrained part of the lock-releasing member for the rear blade. When the coils of the electromagnets are not electrified and the hold member rotates clockwise, the lock-releasing member for the front blade presses a front blade locking member to make it possible to perform an open operation of the front blade, while the lock-releasing member for the rear blade cannot press a rear blade locking member because the lock-releasing member for the rear blade is restrained by the restraining member. As a result, an exposure aperture is fully opened, and it becomes possible to perform observation with electronic finder.
摘要翻译：当保持构件在设定操作中在逆时针方向上在轴上旋转时，装配在保持构件的顶端的按压构件的按压部按压铁构件的按压部，以旋转用于第一叶片的锁定解除构件和用于后刀片的锁定释放构件，使得铁件构件与电磁铁的铁芯构件接触，而接合销按压连接弹簧的臂以顺时针方向旋转限制构件，使得限制部分限制部件移动到用于后叶片的锁定释放构件的限制部分的运动的轨迹中。当电磁铁的线圈未通电并且保持构件顺时针旋转时，前刀片的锁定释放构件按压前刀片锁定构件，使得可以执行前刀片的打开操作，同时锁定释放用于后刀片的构件不能按下后刀片锁定构件，因为用于后刀片的锁定释放构件被限制构件约束。结果，曝光孔完全打开，并且可以用电子取景器进行观察。
