PURPOSE:To prevent the lowering in printing quality due to magnetic interference by lowering possibility of the simultaneous firing of one row, by inserting the printing wires corresponding to adjacent armatures in the pinholes of different rows. CONSTITUTION:Both of two printing wires wherein armatures are adjacent to each other are inserted in the pinholes of different rows in a head leading end part 33. For example, the first printing wire 1 belongs to a row L1 and the second printing wire operated by the armature adjacent to the armature of the first printing wire 1 belongs to a row L2. The first printing wire 1 belongs to the row L1, whereas the third printing wire 3 belongs to the row L2. The second printing wire 2 belongs to the row L2, whereas the fourth printing wire 4 belongs to the row L1, and so forth. Therefore, for example, even when two or more of the printing wires 1, 4, 5, 8, 9, 12, 13, 16, 17, 20, 21, 24 belonging to the row L1 or the whole of one row simultaneously fire, the simultaneous firing of the adjacent armatures is not generated and magnetic interference is reduced. |
