摘要：
A focal-plane shutter for a camera includes two shutter blades each of which comprises two opaque plates. At least one of the two plates has a slit and is held at two points by two arms such that the plates move like a pantograph. The arms are pivotally mounted by eccentric pins to provide for adjusting the parallelism of the blades.
