ABSTRACT:
An electromagnetic striker apparatus. The apparatus includes a core member, a coil associated with the core member and an armature member. The apparatus also includes means for guiding the armature member in movement relative to the core member. In response to actuation of the coil, the armature moves from a rest position to a strike position, whereby a character key is driven against a print support. Under the influence of the guiding means, the armature moves substantially parallel to the magnetic flux lines within the armature.
