As shown in fig. 3, if the actual position of the Y-stage 2 is located at one side of the standard position, all micrometers 3 are mounted to the same side of the standard position, the knob of the micrometer 3 is rotated, and the micrometer 3 pushes the Y-stage 2 to move to the standard position.

If the micrometer 3 is provided with three or more, the intervals between the micrometer 3 are equal to more accurately adjust the position of the Y displacement table 2. The number of micrometers 3 depends on the length of the Y-stage 2, and the longer the length, the greater the number.
