Abstract: A positioning unit includes two or more the laser light sources disposed around a point sensor. Laser light beams from the two or more the laser light sources intersect at an adjustment point separated from a detection point, which is away from the point sensor, by a predetermined distance. The adjustment point is positioned on a desired measurement start point on a work, the point sensor is moved close to the work by the predetermined distance, and a measurement scan of the work is started.

Abstract: A profile measuring instrument usable to perform a rotary scanning measurement and a linear scanning measurement on a workpiece in the form of a revolution solid, includes: a turntable on which the workpiece is mounted, the turntable being rotatable around a predetermined rotation axis; a rotary scanning measurement unit being adapted to measure a displacement of a surface of the workpiece mounted on the turntable; a linear scanning measurement unit being adapted to measure a profile of the surface of the workpiece mounted on the turntable along a predetermined measurement axis; and an aligning mechanism being adapted to relatively move the linear scanning measurement unit and the turntable in a direction intersecting with the measurement axis. The linear scanning measurement unit and the turntable are adjusted to relative positions at which the measurement axis passes through the rotation axis.

Abstract: A traction nut has twist rollers pivotally supported so as to be rotatable in a state of defining an inclination angle with respect to an axis of a drive shaft, the inclination angle being equivalent to a lead angle; an open/close lever provided to switch between a friction-contact state and a disengaged state of the traction nut relative to the drive shaft; and a spring generating a biasing force such that the traction nut is brought into friction-contact with the drive shaft. In response to user operation, the open/close lever puts the traction nut in the disengaged state against the biasing force of the spring. When the user releases the open/close lever, the traction nut returns to the friction-contact state due to the biasing force of the spring.
