摘要： Each actuator comprises a stator part formed with at least one pole piece and a second stator part formed with at least one pole piece and positioned relative to the first stator part so that the pole pieces are spaced apart so as to form a gap. A single coil is associated with one of the stator parts. Each actuator includes an armature member formed with a body of nonmagnetisable material, at least one armature element of magnetisable material and a hammer head. The armature member is supported between the stator parts so that the armature element is located adjacent to the gap. Energisation of the coil causes the generation of a flux which passes across the gap and through the armature element tending to move the armature element into the gap and to cause the hammer head to move into a print position.
