Date Dec. 5, 1985.Tactile reading device presenting a reading surface (3) provided with openings (4) for tactile pins (5) mounted with an axial and reciprocating sliding motion between a projected position and a retracted position with respect to the surface (3) and which are each displaceable between the two positions by one end of an actuating element (9) of which the other end is fixed. The element is capable of a certain displacement by curvature deformation perpendicularly to its axis between two extreme positions by applying a control force. The actuating element (9) is so arranged that its curvature direction is substantially perpendicular to the displacement direction of the tactile pin (5). Displacement emitter means (14) provided between the actuation element (9) and the pin (5) present a neutral point at the vicinity of that of extreme positions of said element (2) wherein the pin (5) is projecting, and a stop (7) prevents the element (9) from assuming a curvature beyond the extreme position.
