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.

Abstract: A double cone stylus includes a shank and a double cone-shaped tip attached to the tip end of the shank, the double cone-shaped tip being a rotationally symmetric body obtained by rotating a triangle having a base extending along the shank around the shank as the symmetric rotation axis. The double cone stylus allows the shape of an inner wall surface of a measurement object with the inner wall surface retracted from an upper reference plane to be measured from above.

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 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.
