<p>The electromechanical writing pen actuator comprises a carriage (4) slideable and oscillating on a guiding bar (5). The carriage (4) supports, orthogonally to the bar (5), rods (17) on which a pen-holder arm (24) is slideable. A movement system composed of step motors (2,3), pulleys (19,22,40,41,46,49,50) and flexible cables (12,20) causes movement of the pen on a cartesian plane. An electromagnet (45) is adapted to cause oscillation of the carriage and therefore the engagement and disengagement of the pen with and from the workplane.</p> |
