ABSTRACT:
A moving base is provided relative to a stage base fixed to a microscope's body and is movable in a linear direction with a specimen placed thereon. A drive wheel coaxial with an operation handle is mounted on the stage base such that it is rotatable. A rail is mounted relative to a mount face of a moving base with an elastic member therebetween such that it is fixed at both ends. The rail is placed in pressure contact with a V groove of the drive wheel by an elastic force of the elastic member. Even if there occur warping of the rail and eccentric state of the drive wheel, the elastic member is correspondingly deformed elastically so that the state of contact of the rail with the drive wheel is uniformly controlled by an elastic force of the drive wheel.
