る微動装置。 In a fine movement device consisting of a rotating cam, a cam follower, a means for pressing the cam follower against the rotating cam, a motor, and a reduction gear device that decelerates the rotation of the motor and transmits it to the rotating cam, the means for pressing the cam follower against the rotating cam is used. The rotational torque of the rotating cam is smaller than the torque required to rotate the motor with the current cut off, and the rotational torque of the rotating cam is transmitted through a reduction gear device to rotate the shaft of the gear that directly meshes with the gear fixed to the motor shaft. A fine movement device characterized in that the magnitude of the force for pressing the cam follower against the rotating cam is selected so as to be greater than the torque required to cause the cam follower to move.
