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.

Levelling device of roughness measuring machine

A measuring device for measuring the contour of an object is disclosed. The device comprises a measuring arm having a first center of gravity adjacent at one end thereof, a second center of gravity adjacent the other end thereof and a fulcrum thereinbetween. The arm is configured such that the first and second centers of gravity and the fulcrum lie in a common line.
