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 probe main body that incorporates the axial motion mechanism, and a probe module that is supported by the probe main body, incorporates the rotary motion mechanism, and supports the stylus. The probe main body and the probe module are detachably coupled to each other with a pair of rollers and a ball capable of positioning to each other. This allows adequate detection sensitivity and a restoring force suitable for the stylus to be obtained at a low cost.

Abstract: A measuring probe includes a stylus, an axial motion mechanism, and a rotary motion mechanism. The axial motion mechanism includes a pair of first diaphragm structures that allows a moving member to be displaced, and the rotary motion mechanism includes a second diaphragm structure that allows a rotating member to be displaced. The second diaphragm structure is disposed between the pair of first diaphragm structures in an axial direction. The respective first diaphragm structures are disposed at a symmetric distance with respect to the second diaphragm structure. This can reduce the length in the axial direction and weight thereof and also reduce shape errors and improve measurement accuracy.

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.
