摘要

Speed indicating device on a rectilinear scale for tacheometers in general, particularly for motor vehicles, characterized by the fact that a flexible tape provided with an indicator mark and arranged so that it is set in motion by the sensitive tachymeter element, when turning it is combined on the one hand with suitable means to enable it to move, in its movement, along a graduated scale rectilinear in one direction or the other, according to the direction of rotation of the sensitive element itself, and on the other hand with means intended to maintain it at the desired tension during the displacement that it carries out.
