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: The present invention provides a lens substrate stacking position calculating apparatus capable of calculating a stacking position at which the number of lens sets whose optical axis deviation falls within an allowable range is maximized, when a plurality of wafer lens arrays are bonded together even if the position of each lens formed on a wafer substrate is deviated between wafer lens arrays to be stacked. The lens substrate stacking position calculating apparatus calculates the positional relationship of two or more transparent substrates to be stacked when the two or more transparent substrates on which a plurality of lenses are two-dimensionally arranged are stacked to form a plurality of lens sets each including two or more lenses. A position of each lens is specified in advance in a common coordinate system.

Abstract: A measuring probe for measuring a screw groove of a relatively rotatable ball screw includes a stylus having a tip end portion configured to contact the screw groove, a radial-direction displacement mechanism configured to support the stylus so as for the stylus to be displaceable in an X direction toward an axial center of the ball screw, an axial-direction displacement mechanism configured to support the stylus so as for the stylus to be displaceable in an axial direction (Z direction) of the axial center, and sensors configured to detect displacement of the stylus produced by the radial-direction displacement mechanism and the axial-direction displacement mechanism. This enables high-accuracy measurement of a predetermined position of a side surface of a relatively rotatable work.

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 contact probe includes a stylus and an optical detector configured to detect a posture of the stylus optically. An illumination subject portion is formed on the stylus and has three or more reflection surfaces. The optical detector includes three or more fibers, a light source, a condenser lens group, and a wavelength detector. The wavelength detector calculates posture information of the stylus on the basis of wavelength variations of reflection light beams that are caused by variations of intervals between the condenser lens group and the three or more reflection surfaces, respectively. The contact probe acquires coordinates of a position of the contact to the object to be measured on the basis of posture information obtained by the optical detector.
