PURPOSE:To enable stabilization and rationalization of dot density, and to obtain a high-printing quality by specifying an extent of gapping between a wire guide runner and a wire which goes through the runner. CONSTITUTION:A wire guide 13 is incorporated in a circumferential groove of an ink supply guide 12, and a wire 11 goes through a runner 13a of the wire guide 13, and a gap of 5-50mum is formed as an ink supply passage between the wire and the runner. Additionally, the length of the gap in its axial direction is made to be 10mm or under. By the above, if the wire 11 hits a platen 31 through a recording paper 30 to cause transferring on the recording paper, an almost same amount of the ink as consumed by the above is supplied from an ink tank to the vicinity A of the front end surface of the wire. Therefore, a fixed dot density is maintained. And, the shape of the dot becomes a regular circle, and a precision of positioning is satisfactory. |
