    • A focal plane shutter having a front film and a back film which expose a charge-coupled device to light as they move back and forth between a cover plate and a base plate, between a charging position and a discharging position at a certain time interval. The focal plane shutter includes at least one lever member which is connected to the front film and/or back film, and which amplifies an impact force generated during a charging and a discharging movement of the front film and/or back film using a lever action. An elevating member slides in a direction parallel with the movement of the front film and/or back film by the impact force amplified in the lever member. An impact absorbing unit regulates the sliding movement of the elevating member to absorb impact energy generated by the movement and stop of the front film and/or back film.
    • 具有前膜和背膜的焦平面快门,当电荷耦合器件在盖板和基板之间来回移动时,以一定的时间间隔在充电位置和放电位置之间曝光。 焦平面快门包括至少一个杠杆构件,其连接到前膜和/或后膜,并且利用杠杆动作放大在前膜和/或后膜的充电和排出运动期间产生的冲击力 。 升降构件通过在杆构件中放大的冲击力沿与前膜和/或后膜的移动平行的方向滑动。 冲击吸收单元调节升降构件的滑动运动,以吸收由前膜和/或后膜的运动和停止产生的冲击能。
