摘要： The printing device comprises a printing head having a row of printing elements, e.g. 18 wires 31 actuated by corresponding electro-magnets for printing symbols and characters in conformity with dot matrices. The inclination of the row relative to the direction of movement of the printing is variable. With the row vertically aligned, the height 1 of the 18 wires is equal to that (h + b + h) of the two lines of printing as a result of which it is possible to print two rows of characters simultaneously. By inclining the head and suitably selecting the speed of movement it is possible to print one line at a time with high definition dot matrices.

摘要： Each needle (5) of the printer has an associated electromagnet (9) with a generally elongate movable armature (8) having a first end (12) and a second end (13) which can selectively push the needle during printing as a result of a pivoting movement about a step formation (16) facing the electromagnet (9). The step formation (16) divides the armature into first and second portions (14, 15) facing the first and second ends (12, 13) respectively, and faces the respective electromagnet (9) in such a position that the second portion (15) of the armature (8) at least partially faces the electromagnet (9).

摘要： A ballistic type wire printing head comprises a metal front support (11) for guiding the printing wires (23) and supporting a group of actuating electromagnetic units (37, 39, 41) associated with the wires. The armatures (41) of the electromagnetic units are pre-assembled on a disc (40) of plastics material. A rear cover (59) which is also of metal encloses the electromagnetic units and in its interior supports spring spider (58) which co-operates with all the armatures of the electromagnetic units. The electromagnetic units have a common internal, ferromagnetic support (35) from which heat is conducted to the front support (11) and cooling fins (25). In a second embodiment, the printing head also comprises a second group of electromagnetic units associated with another series of printing wires. In that case, an intermediate metal member acts as a cover member for the first group of electromagnetic units and as a support for the second group of electromagnetic units.

摘要： A wire printing head (10) for a high resolution printing machine is provided together with a method for its manufacture. The printer is of the type comprising a printing platen (12) for a recording medium (17) and a carriage (11) transversely movable with respect to the printing platen and mounting the printing head. The head comprises a guide matrix (29) adjacent the platen and a plurality of wires or needles (28) guided by the matrix. The wires are capable of longitudinal movement and define on the recording medium printing dots having an area less than the nominal section Sn of the wires. Each wire comprises a front portion (72) of constant section (Sr) which is reduced with respect to the nominal section (Sn) and extends for a minimised length of between 0.5 and 4 times inclusive the diameter (Dr) of the reduced section. The guide matrix supports slidably a terminal portion of the wires comprising the nominal section and lodges with play the frontal portion having the reduced section.

摘要： The needle printing head comprises a plurality of electromagnets having fixed cores (18), each with two limbs (27, 28) which are mounted in a ring within a containment body (21). Movable armatures (19) are disposed in a radiating array in front of coplanar terminal surfaces (41, 42) of the fixed cores (18). The movable armatures (19) each have a step configuration (46) for oscillating on the terminal surface (41) of the more outward limb (27), a surface (44) for closing the magnetic flux which, with the terminal surface (42) of the more inward limb (28) constitutes a main air gap, and an end (47) capable in printing of engaging a needle (16) by means of a corresponding connecting limb (48). In order to improve the level of magnetic efficiency, there is provided a magnetically conducting disc (66) of ferro-magnetic material and comprising a plurality of spokes (62) projecting radially inwardly from a peripheral annular portion (65) and disposed in juxtaposed alternating relationship with the movable armatures (19) so as to constitute auxiliary air gaps and for closure of the magnetic flux which is common to the armatures (19) and the cores (18).
