Title: Wire printing device

Abstract: A wire printing device comprises a frame removably mounted on a carriage which can move parallely to a platen. On the frame is removably mounted a guide block of resin material which guides a plurality of printing wires individually actuatable by a plurality of electromagnets, mounted on the frame. For an easy assembly of the printing device, a terminal guide is removably mounted on the frame for guiding the printing wires in proximity of the platen. Moreover, between the terminal guide and the guide block, a lubricating pad is disposed at contact with the printing wires and an oil container, mounted on the guide block, is connected through a wick to the pad for holding it constantly impregnated.
