ABSTRACT:
A dot matrix pin print head is formed of a rear electromagnet drive assembly (1) and a front pin-guide assembly (2) located opposite a print support (3), the electromagnet drive assembly (1) consisting of a plurality of identical electromagnet/flap-armature systems corresponding to the number of print pins (9) and each of the electromagnet/flap-armature systems having a U-shaped magnet yoke (10) with an oppositely-disposed, pivotably mounted flap armature (12). With this arrangement, the mass of the flap armature (12) is reduced, its operative guidance is improved and the magnetic flux is optimized by further providing the flap armature (12) with at least one projection (21) which extends transverse to the longitudinal extension of the armature and which is received in a recess (22), and by pivotably supporting the flap armature (12) at a location substantially opposite the projection (21).
