  • Levelling device of roughness measuring machine
    Patent number: 4888984
    Abstract: The present invention is concerned with a levelling device of a roughness measuring machine and includes a device for searching a tilt angle of the center locus of a measured value of the roughness to a base line, a device for setting a tolerable tilt angle of the center locus, a comparator for determining whether the tilt angle is included in the tolerable tilt angle or not, and a device for changing the position of an object to be measured in accordance with the result of comparison by this comparator. When the tilt angle is determined to be not included in the tolerable tilt angle, a position change device is operated to change the position of the object, so that scale-out can be avoided.
