- the cam follower 45 moves in the vertical direction (Z direction) by being pushed by the peripheral surface of the cam 43 as the cam 43 rotates. Since the cam follower 45 is provided integrally with the link rod 44, the cam follower 45 moves in the vertical direction, whereby the link rod 44 rotates around the Y axis about the shaft portion 44a.
- the center C2 of the cam follower 45 is arranged so as to be shifted in the X direction with respect to the rotation center C1 of the cam 43.

Further, since the contact portion 46 is disposed on the tip side of the cam follower 45, the amount of movement of the contact portion 46 in the vertical direction is larger than that of the cam follower 45.

Further, for example, a configuration may be applied in which the rotation amount or rotation position of the cam 43 is detected by a sensor or the like, and the drive of the drive source 41 is stopped when the cam follower 45 reaches the maximum diameter portion 43b.
- a contact-type limit switch that operates at a position where the tip end portion of the link bar 44 is most raised is arranged, and when the limit switch is operated (that is, when the cam follower 45 reaches the maximum diameter portion 43b), the drive source 41 is provided.
- a configuration for stopping the driving may be applied.
- the above-described sensor or limit switch either a contact type or a non-contact type may be used.
- the revolver unit 200 described above can move the revolver support portion 30 (that is, the selected objective lens 32) in the vertical direction by operating the operation portion 14 provided on the base 11.
