摘要： A shutter blade is actuatable by a driver which can be locked in a shutter setting position by a locking lever assembly comprising a first lever having a bent end engageable with the driver and a second lever having an iron member attractable by an electromagnet which, when energized, causes the first and second levers to be angularly moved in unison in a direction to release the driver for actuating the shutter blade. The second lever is lockable against movement to actuate the driver by a reciprocable follower movable in response to operation of a quick return mirror mechanism. When a shutter button is depressed to move the mirror upwardly for starting an exposure operation, the second lever is disengaged from the follower, and attracted by the electromagnet as energized to release the driver. When the exposure operation is finished, the mirror is lowered to enable the follower to lock the second lever against movement. The first lever is then in a position capable of locking the driver in the shutter setting position.
摘要翻译：快门叶片可由驾驶员致动，驾驶员可以通过锁定杆组件锁定在快门设置位置，锁定杆组件包括具有可与驾驶员接合的弯曲端的第一杆和具有可被电磁体吸引的铁构件的第二杆，使得第一和第二杠杆沿着一个方向成角度地移动，以释放用于致动快门叶片的驱动器。第二杆可锁定以防止运动，以通过能够响应于快速返回镜机构的操作而可移动的可往复运动的跟随器来致动驾驶员。当按下快门按钮以向上移动镜子以开始曝光操作时，第二杆从跟随器脱离，并被电磁体吸引而被驱动以释放驾驶员。当曝光操作完成时，镜子被降低以使跟随者能够锁定第二杆以防止移动。然后，第一杆处于能够将驾驶员锁定在快门设定位置的位置。
