Shuttle type line printer
 The present invention relates to a shuttle type line printer which is characterized in that among members constituting printing elements of the shuttle type line printer, such as a permanent magnet, an electromagnet, a yoke and a printing hammer, the permanent magnet occupying a considerable proportion of the total weight of the printing elements is separated from the shuttle to reduce the weight loaded on the shuttle, and the permanent magnet separated from the shuttle is used as a part or all of a balancer indispensable for removing lateral vibrations having fatal influences on the shuttle type line printer. In a conventional shuttle type line printer, all of printing elements such as a permanent magnet, an electromagnet, a yoke and a printing hammer are loaded on one shuttle and a balancer having a weight corresponding to a heavy total weight of the shuttle should be disposed to remove undesirable lateral vibrations. The shuttle type line printer of the present invention is advantageous over this conventional shuttle type line printer in that the permanent magnet alone or with a slight auxiliary weight is sufficient as the balancer and the weight and space required for the balancer in the conventional printer can be removed completely or partially, with the result that the size and weight of the printer as a whole can be reduced, the printing speed can be increased and the energy consumption can be decreased.
