摘要： The disclosure of this invention pertains to an inspection machine for comparing different profiles of a workpiece with profiles of corresponding masters. A probe is supported for movement relative to the workpiece and an image of a pointer connected to the probe is projected by an enlarging optical system on to a viewing screen on which the master profiles are delineated in spaced apart relationship. The screen is movable relative to the optical system to bring the respective masters into register with the image as required.
