Abstract

PURPOSE:To obtain a print head capable of fine regulation of the stop position of a free end of an armature by providing a cover member having a stopper in contact with a free end of an energized armature and anoter cover member supporting said cover member detachably. CONSTITUTION:A stopper 22 provided on a cover member 23 is inserted into a through hole made on a rear cover 24 and said member 23 is fixed to the rear cover 24 through a skim 25 of a desired thickness between said member 23 and the rear cover 24. The stop position of the free end of an armature 18 brought into contact with the stopper 22 can be adjusted finely, easily and correctly, and working and assembly of parts can be improved in efficiency.
