Abstract
A linear measuring device comprising a scale fixed on a supporting structure along which a slide can slide. A transducer connected to the slide permits, in cooperation with the scale, determination of at least one coordinate of a point connected to the slide in a system of coordinates connected to the supporting structure. The transducer is fixed to the slide at three points by a mounting device having at each point a screw engaged in a partially threaded opening of a column and a spring. In acting on one of the screws at each of the said points, the spacing can be changed between the detection device and the slide. The spring keeps the spacing as large as the engagement of the screw in the said opening permits. The detection device is of the capacitive or electro-optical type and is mounted on a transducer support. The slide slides by means of rollers, part of the rollers rolling on guide surfaces belonging to the same plane as the surface of the supporting structure to which the scale is fixed.
