ABSTRACT:
An improved daisy-wheel printer of the type in which a hammer contacts a daisy-wheel to print characters is designed so as to facilitate the position setting of the hammer and other movable parts for actuating the type head. According to the design, it is possible to shift the type head with a reduced force and to eliminate the necessity for the adjustment of same during assembly. The stability and tilting operation of the carriage is enhanced. The carriage is stably secured, eliminating lateral oscillation of the same without the necessity of manufacturing the carriage using highly precise machining. The ribbon cartridge is held in such a manner as to be able to move rapidly, with reduced generation of vibration and with high durability. The design facilitates the determination of relative positions of constituents of the magnet device which drives the hammer, and facilitates fine adjustment of the same. The magnet assembly includes a substrate and an arm extending from the substrate. A pivotally-mounted armature for impacting the hammer is mounted on the magnet assembly and swings between plural stopper means disposed at the limits of pivoting travel of the armature. The stopper means may advantageously be eccentric shafts that may be rotated and fixed in position so as to make fine adjustments to the limits of pivoting travel of the armature.
