FEELER DEVICE, PARTICULARLY FOR COPYING MACHINES

摘要

The device comprises a support structure movable along at least a first reference axis, a feeler member carried by the structure so as to be able to effect limited relative displacements along the axis relative to a predetermined rest position, and detector means for providing electrical signals indicative of the magnitude and direction of the movements of the feeler member relative to the structure. According to the invention, the feeler device comprises at least a first intermediate structure supported by the structure by means of first blades which can bend in a plane parallel to the reference axis; the feeler member is also supported by this intermediate structure by means of second blades having bending characteristics substantially the same as those of the first blades in a plane parallel to the reference axis. The feeler device may be made so as to be able to detect movements of the feeler member relative to the support structure along two or three independent axes as well. Figure 1.
