Patent ID: 7729048

Claim:
A unit-type microscope system, comprising: a stand unit that comprises a nosepiece that holds a plurality of objective lenses achieving different magnifying powers, a first drive device equipped with a first drive mechanism for moving the nosepiece up/down along an optical axis of the objective lens and a first operation device that adjusts focus on a specimen by operating the first drive device; and a base unit that comprises a stage device on which the specimen is placed, a second drive device equipped with a second drive mechanism for moving the stage device up/down along the optical axis of the objective lens, a second operation device that adjusts the focus on the specimen by operating the second drive device and a lamp used to illuminate the specimen through transmitted illumination, wherein: the stand unit further comprises a first connecting surface configured for connecting the stand unit to the base unit and a second connecting surface configured for connecting the stand unit to a device other than the base unit when the stand unit is removed from the base unit; wherein in a first configuration achieved by connecting the stand unit to the base unit via the first connecting surface of the stand unit, a displacement range over which the objective lens is capable of moving up/down by the first drive device and a displacement range over which the stage device is capable of moving up/down by the second drive device are different from each other; and, in the first configuration, the focus can be adjusted on the specimen via either one of the first operation device and the second operation device alone; and wherein, in a second configuration achieved by connecting the stand unit to the device other than the base unit via the second connecting surface of the stand unit, the focus is adjusted on the specimen via the first operation device.
