Abstract (en)
The print wires (16) are operably supported in one-piece bearing and guide passage block member (10) in an elongated wire housing with wire actuating armature members (18) arranged in a circular array between radially innermost (45) and outermost (48) poles of electromagnetic armature actuating devices (23, 24) and an armature retaining cover member (29) centrally adjustably connected to the wire housing and having armature confining slots (40, 41) holding the armatures in pivotally displaceable operable association with the poles, the armatures being pivotally supported on the radially outermost edge surfaces of the outermost poles with or without resilient biasing devices continuously holding the armatures in engagement with the pole pivot surfaces without applying a moment of force and peripheral portions of the cover member being mounted in rigid abutting engagement with end surfaces of the outermost poles.
