Abstract

A stylus has a detection element support part 1E for supporting and fixing piezoelectric elements 21 to 24 and a rod 1D placed on the detection element support part 1E. The detection element support part 1E has a plurality of flange parts 1F each being regular polygonal in cross section orthogonal to the axis of the rod 1D. The displacement detection elements are attached to the sides of the flange parts 1F in a state in which they are inclined at a predetermined angle α relative to the axis of the rod 1D. If a measured force in a torsion direction Q or in a bend direction P occurs on the rod 1D through a contact ball 1A, the measured force is transmitted along substantially the length direction of the piezoelectric elements 21 to 24.

Claims9

Dependent claims

A touch signal probe comprising:

a stylus having a contact element for coming in contact with a measured object at a tip;
and
a plurality of displacement detection elements attached to the stylus, for detecting the contact element coming in contact with the measured object so that a contact sense signal is generated based on a signal output from the displacement detection elements,
wherein the stylus has a detection element support part for supporting and fixing the displacement detection elements and a rod disposed on the detection element support part, the detection element support part having a plurality of flange parts each being regular polygonal in cross section orthogonal to an axis of the rod, and wherein the displacement detection elements are attached to at least two of sides of the flange parts in a state in which they are inclined at a predetermined angle α relative to the axis of the rod.
