ABSTRACT:
Force detector (5) fitted with a blade carrying a strain gauge (12) and with a fixed support (10) and a mobile support (11) in which are respectively accommodated a first and second end of the said blade, the relative displacements of the two supports enabling the forces applied to the mobile support to be detected. In order to accommodate at least one of the said ends in its own support, the said support comprises a U-shaped member (13), between the two branches of which is inserted the said end bearing on slightly elastic contacts. A tactile screen is formed with the help of a plurality of such force detectors accommodated in a mobile plate (22) and a fixed frame (21). By coupling the two latter elements by means of suspensions (24.sub.1, 24.sub.2) and elastic fasteners (25.sub.1, 25.sub.2), the pressure forces acting on the mobile plate are, in a vertical position, decoupled from the intrinsic weight of the latter.
