MEASURING DEVICE OF PENPOINT MOVEMENT PARAMETERS Russian patent published in 2013 - IPC G01B7/00 

FIELD: measurement equipment.

SUBSTANCE: measuring device of penpoint movement parameters includes housing, sensitive element with piezoelectric detectors connected to electric diagram. Force receiving element is made of two longitudinally connected elastic bars connected at their end faces by means of a ball hinge, on which the arrangement is made for force transfer element in the form of a ball bearing installed with its inner race on force receiving element in maximum deflection zone; sensitive element is made in the form of deformed outer race of the above bearing, which is located concentrically to inner race. On inner surface of deformed race there are openings for arrangement of piezoelectric elements, and bearing cage is fixed against annular displacement relative to support ring so that each bearing ball contacts the working surface of piezoelectric element so that centres of balls coincide with direction of radial displacements of sensitive element of the sensor.

EFFECT: enlarging functional capabilities of the device owing to continuous measurement of movement components of penpoint when writing a penscript, and providing the accuracy of facsimile detection.
