摘要： 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.

摘要： A surface roughness measuring instrument is provided with a rotary drive mechanism configured such that two rollers support a sphere at three points, yet the driving torque applied to the sphere at those three points all give an equal tangential velocity. A detector arm is provided between the mounting section for mounting to the surface roughness measuring instrument itself and a tip section which holds skids which make contact with the object to be measured, so that these two sections are able to rock relative to each other about an axis in the direction in which the detector arm extends. Surface roughness in the circumferential direction of a body of rotation can be measured accurately and stably.

摘要： A levelling apparatus utilizes a control system for obtaining the average plane of an object placed on a mounting member from the coordinates of at least three points in a specified area of the object including points which are not on the same straight line and for instructing supporting system for supporting the mounting member to control the average plane so as to have the desired attitude. In this way, three-dimensional attitude control of the object is enabled.
