Abstract

PURPOSE: To avoid the application of great mechanical impact on an armature lever by inserting a cushion material made of a nonmagnetic material between a yoke generating a magnetism and the armature lever in a high speed printer.
CONSTITUTION: A 50W100μm thick nonmagnetic plating 52, e.g., copper plating, etc., is formed on the top of a yoke 42 attached to a base 46. When electrically energizing a coil 44 wound around the yoke 42, the yoke 42 is magnetized, an armature lever 48 is attracted by the yoke 42 and turned, and then a hammer is driven and printing is made. In this case, when the aperture g1 between the yoke 42 and the armature lever 48 is zeroed, the nonmagntic plating 52 becomes a cushion to absorb impaction applied to the armature lever 48. The nonmagnetic plating 52 may be provided on the armature lever 48 side, and also nonmagnetic material such as Mylar, etc., may be laid in place.
