PURPOSE:To make it possible to easily perform the pin exchange of a divided unit, by constituting the titled unit so that printing magnet lines are divided into several units and movable magnets are not inserted into permanent magnets provided to the divided end surfaces. CONSTITUTION:In a printing magnet coil constituted so that movable coils 11, 11' having printing pins 14 mounted to the leading ends thereof and permanent magnets 16 each for generating magnetic flux to a direction crossing said movable coils 11, 11' are arranged in a line form and a magnet line formed by inserting two movable coils 11, 11' between the permanent magnets 16 are arranged in two upper and lower lines, the printing part of the printing magnet coil is divided to form divided parts each of which has 2(N+1) numbers of the permanent magnets 16 and 4N numbers of the printing pins 14 and movable coils 11 are not inserted into the permanent magnets 16 provided to the divided end surfaces. |
