Claim:
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 comprising: at least one lever member which is connected to the front film and/or the back film, and which amplifies an impact force generated during a charging and a discharging movement of the front film and/or the back film using a lever action; an elevating member which slides in a direction parallel with the movement of the front film and/or the back film by the impact force amplified in the lever member; and an impact absorbing unit which constantly pressured the elevating member to regulate the sliding movement of the elevating member to absorb the impact energy generated by the movement and stop the front film and/or the back film.
