Abstract: A measuring probe includes a stylus having a contact part to be in contact with an object to be measured, an axial motion mechanism having a moving member that allows the contact part to move in an axial direction, and a rotary motion mechanism having a rotating member that allows the contact part to move along a plane perpendicular to the axial direction by means of rotary motion. The measuring probe includes a main body housing that supports the axial motion mechanism, a module housing that supports the rotary motion mechanism, and a displacement detector supported by the main body housing for detecting displacement of the moving member. The measuring probe with this configuration ensures high measurement accuracy while keeping a low cost.

Abstract: A contact probe includes a stylus, a spring, a magnetic body, and a permanent magnet. The stylus is displaceable in an X direction and a tip of the stylus makes contact with a measured object. A first end of the spring is fixated and a second end provides spring force along the X direction. A position of the magnetic body is fixated with respect to the stylus. The permanent magnet is arranged separated from the magnetic body so as to generate a magnetic force along the X direction between the magnetic body and the permanent magnet.

Abstract: A measuring force includes a stem, an arm, a detector, a rotation fulcrum, and a measuring force adjuster. A probe which makes contact with a workpiece is provided on the stem. An end portion of the arm is joined to the stem. The rotation fulcrum acts as a fulcrum for a rotating motion of the stem and the arm. The detector detects a displacement amount of the rotating motion of the arm. A crossed spring of the rotation fulcrum imparts on the stem and the arm a torque around an axis of the rotating motion in accordance with the displacement amount of the rotating motion. The measuring force adjuster imparts on the arm and the stem a torque, in a reverse direction of the torque generated by the crossed spring, by an attraction force generated by a magnetic force between at least two magnetic members mutually arranged at opposite ends.
