PRINT TRAIN PERMITTING ACCELERATED PRINTING SPEEDS IN A LINE PRINTER

摘要

A print train of predetermined length and comprised of a plurality of type carrying blocks is provided with an increased number of hammer impactable type characters to thereby enable the realization of significantly accelerated printing speeds, the type blocks being individually and alternately driven to advance a toothed belt to which the blocks are separately coupled around a pair of rotatable sprockets, said accelerated printing speeds being realized without an accompanying degradation of printing quality resulting from the closer spacing of the adjacent characters, means being provided to shield the characters adjacent to an impacted character against the striking force of the hammer associated with such impacted character.
