Device for coupling and releasing a daisy wheel type member

摘要

A typewriter (not illustrated) using a daisy wheel as the type carrying member and having a unit which drives the daisy wheel element to rotate about its axis and a device for coupling the daisy wheel element onto the drive unit. The coupling device substantially comprises a pin which engages a hole in the daisy wheel element; first resilient means carried by the unit and operable to transmit to the daisy wheel element an axial thrust in a first direction; second resilient means operable to transmit to the daisy wheel element an axial thrust in a direction opposite the thrust generated by the first mentioned means; and manual control means which act on the said second resilient means in such a way as to compensate, if actuated, the thrust generated by such second resilient means.
