Abstract
A device driving a corrector ring of a corrector ring mounting objective lens mounted to an objective mounting and dismounting section of a revolver includes a rotation driving mechanism having a motor and a turning effort transmitting section which transmits a turning effort of the motor to the corrector ring of the corrector ring mounting objective lens mounted to the revolver to drive the corrector ring; and a connection unit for connecting the turning effort transmitting section to the corrector ring of the corrector ring mounting objective lens introduced into an observation optical path in association with a switching operation performed by the revolver and disconnecting the turning effort transmitting section from the corrector ring of the corrector ring mounting objective lens removed from the observation optical path.
