Patent ID: 7593173

Claim:
A corrector ring driving device of a microscopic objective lens provided with a corrector ring which drives the corrector ring of a corrector ring mounting objective lens mounted to an objective switching device having a plurality of mounting and dismounting sections for mounting and dismounting a plurality of kinds of objective lenses, to each of which is mounted the corrector ring mounting objective lens, and allowing a desired objective lens to be introduced into an observation optical path by rotating on a shaft fixed to a microscope body, the corrector ring driving device comprising: 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 objective switching device to drive the corrector ring; and connection means for connecting the turning effort transmitting section to the corrector ring of the corrector ring mounting objective lens introduced into the observation optical path in association with a switching operation performed by the objective switching device and disconnecting the turning effort transmitting section from the corrector ring of the corrector ring mounting objective lens removed from the observation optical path.
