Acting on the mechanism component), the drive mechanism component is displaced downward by X amount. Next, when the motor is stopped, the frictional forces F1 and F2 are eliminated, so that the amount X of the drive mechanism component displaced by the frictional forces F1 and F2 gradually recovers upward. The same applies to the case where the detector feed device 46 is fed downward.

きないという問題がある。The vertical position of the detector feeder 46 is a reference for the measured surface roughness. If the vertical position fluctuates during the measurement, accurate measurement cannot be performed. Therefore, as shown in the flow chart of FIG. 9, after the detector feeding device 46 has been sent upward or downward (steps 71, 72, 73), the driving mechanism components have frictional forces F1 and F
Wait until the amount X displaced by 2 is restored (Step 7
The measurement must be performed from step 4) (step 75), which causes a problem that the efficiency of the measurement is reduced. Further, after the detector feeding device 46 is sent upward or downward (steps 71, 72, 7).
3) When measuring immediately, it is necessary to use a magnification that does not affect the displacement X, and there is a problem that high-magnification measurement cannot be performed.

When the feed screw 37 rotates and the slider 41 is fed in the target direction (forward direction), the displacement of the drive mechanism component is input from the detection unit 17 to the calculation unit 16 (step 63). Is greater than or equal to a predetermined amount, the feed amount and the feed direction (a direction opposite to the previous direction) are output to the drive control unit 15 so that the displacement amount becomes equal to or less than a predetermined value. Thus, the drive control unit 15 controls the drive mechanism of the vertical feed device, rotates the feed screw 37, and feeds the slider 41 in the opposite direction to the front (step 64). The calculating section 16 calculates the signal of the sent amount (including the direction) always output from the drive control section 15 (step 65). If the fed amount does not reach the target, the shortage of the fed amount and the feeding direction are drive-controlled. Part 15
Output to By repeating this, the slider 41 is fed by a target feed amount while tracking the displacement amount of the drive mechanism component to be equal to or less than a predetermined value. Therefore, measurement can be started (step 67) immediately after the slider 41 is stopped (step 66). .
