Abstract
A device for guiding and controlling displacement of a mobile member relative to a fixed member parallel to a translation axis comprises at least one pair of parallel flexible flat plates. These plates are transverse to and spaced along the axis, one end of each plate being rigidly attached to the mobile member and the other end of each plate being rigidly attached to the fixed member. The rigidly attached parts of each plate are at the same distance from the axis. A transverse extension on the mobile member extends approximately parallel to the plates towards the fixed member, over at least half the transverse distance between the respective parts of the plates rigidly fixed to the mobile member and the fixed member. An actuator applies a force to this extension parallel to the axis at a point substantially equidistant transversely from the respective parts of the plates rigidly fixed to the mobile member and the fixed member.
