The printing head has a core block (1) having a projection (2) for restricting oscillations of printing levers (30), said projection being provided at the inside central portion of said core block (1), and a printing lever driving coil provided on the peripheral edge portion of the core block (1). A nose block (50) provided with a nose (51) for guiding the printing wires (31) and a disk part (52) opposite to the core block (1) is placed on the core block and the printing levers (30) are pivotally supported therebetween.</p> |
