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 sensor, and two parallel substantially planar plates. The stylus has a contact. The sensor has a substantially planar shape and includes a fixed portion, at least three thin-walled portions each formed of a planar plate and having a strain sensor vapor-deposited thereon, and a movable portion to which the stylus is mounted and linked to the fixed portion via the thin-walled portions in at least three locations. The two parallel substantially planar plates are connected to the fixed portion on opposing sides and sandwich the movable portion so as to maintain a predetermined distance between the movable portion and the two parallel substantially planar plates and limit movement of the movable portion to a movable range. The sensor outputs a contact signal due to the strain sensors deforming in response to a measurement force from the stylus.

Abstract: A lever-type measuring machine swinging around a supporting point includes a stylus measuring a shape of a measured object, an arm having a first end connected to the stylus and a second end connected to the supporting point, and a balancer having a first end connected to the supporting point. The balancer is formed of a material having high specific flexural rigidity. The lever-type measuring machine enables more accurate measurement.

Abstract: A stylus support member extends in a first direction. A first and second elastic body attaching members are spaced aside from each other in a second direction are arranged spaced aside from the stylus support member in the first direction, and are connected to each other by first and second members. A first elastic body is arranged between a holder and the first elastic body attaching member. A second elastic body is arranged between a first member and the first elastic body attaching member. A third elastic body is arranged between a second member and the second elastic body attaching member. A fourth elastic body is arranged between the holder and the second elastic body attaching member. A detector detects displacement in the second direction of the stylus support member. The first to fourth elastic members perform lever motion of a single degree of freedom.
