摘要

Metrology instrument, essentially characterized by the provision, inside an advantageously cylindrical box, of a rotary device coaxial with it and constituted by a shaft supported between bearings housed in tubular formations belonging to the internal faces of the bases of the box, carrier of a pinion of precision conjugate with a zipper also of precision, coincident with a generatrix of a cylindrical shank capable of sliding in a direction perpendicular to that of the axle-shaft, guided by two tubular formations coaxial and diametrically opposed on the cylindrical surface of the box, with emergency, on the one hand, the operating end of the rod, constituting a functional foot in order to the measurements to be made, and emergency, on the other hand, the head of the stem, housed in a protective cap, solidary of the box, the shaft-shaft of a photoelectric transducer device being a carrier conventional cog of the revolutions of the shaft, corresponding to the displacement of the transverse shank.
