Surface roughness and/ or contour shape measuring apparatus

摘要

A surface roughness and/or contour shape measuring apparatus for measuring the surface shape of a work measurement surface by moving a probe supported on a cantilever and kept in contact with the work measurement surface and by detecting the displacement amount of the probe is disclosed. The surface roughness and the contour shape of a stepped work bottom portion having bank portions and the bottom portion can be easily measured. The surface roughness and/or contour shape measuring apparatus (1) includes a moving unit (8) for moving the work and the probe (9) relatively to each other in the direction (X) perpendicular to both the longitudinal direction (Z) of the probe (9) and the longitudinal direction (Y) of the cantilever (7).
