An armature (4) is coordinated to each print pin (1) with a pin guide case (9) and in a coil support case (14) an electromagnetic coil (3) and magnet yokes (3a, 3b) in a matrix pin print head. In order to improve the system of the individual armatures (4) and their support, all armatures (4) are maintained in operations with a shaped sheet metal (19, 19a) and are connected thereby to each other and thereby form a unit (4, 19). Thus unit (4, 19) is centered via in the pin guide case (9) via several cogs (25), distributed over the circumference, and cogs are provided, which center this unit (4, 19) also in a coil support case (14).
