ABSTRACT:
Printer device in which a striking movement is imparted to a striking member (6) for transmitting a print (5) via an ink ribbon (3) to a paper (2) or the like bearing against an abutment (1). The striking movement of the striking member (6) is effected by means of a motion generator unit (8, 8A, 8B) of a giant magnetostrictive material consisting of an alloy between heavy earth metals and iron, cobalt or nickel, particularly an alloy between one of several of the substances terbium, dysprosium, samarium and iron. One end of the motion generator unit (8, 8A, 8B) is fixed to a supporting structure (9) and the opposite end thereof is fixed to said striking member (6). The motion generator unit (8, 8A, 8B) is surrounded by a magnetic coil (10, 10A, 10B) for applying a variable magnetic field to the motion generator unit, said magnetic field being variable in dependence of current supply to the coil. The current supply is controlled by using control means for controlling the supply of current to the coil in accordance with a predetermined programme in order to achieve a desired striking movement.
