ABSTRACT:
A buffer comprises a specially designed bearing for supporting the rotation axis of a rotatable mirror. The bearing structure is so designed that when the rotation of the mirror is stopped by a stopper, the bearing can shift the rotation axis in the direction in which force is applied to the rotation axis. This shift takes place at the moment of mirror stop. Immediately after the shift, the rotation axis is returned to its original position by a biasing force.
