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

摘要： A needle or wire printing head comprises a plurality of electromagnets with fixed cores, each with two limbs, which are mounted in a ring within a containment body. Movable armatures are disposed in a radiating array in front of coplanar terminal surfaces of said cores. The movable armatures each have a step configuration for oscillating on the terminal surface of the more outward limb, a surface for closing the magnetic flux which, with the terminal surface of the more inward limb constitutes a main air gap "G" and an end capable in printing of engaging a needle by means of a corresponding limb. A unitary return group accomodates a plurality of coil springs in a prestressed state for restoring the movable armatures. There is also provided a magnetically conductive conveying disc of ferro-magnetic material and comprising a plurality of spokes for closure of the magnetic flux which is common to the armatures and the cores.

摘要： A wire printing head 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 for a recording medium and a carriage transversely movable with respect to the printing platen and mounting the printing head. The head comprises a guide matrix adjacent the platen and a plurality of printing wires or needles 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 of constant section (Sr) which is reduced with respect to the nominal section (Sn) and extends for a minimized 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： A printing device comprising a printing head having 18 wires actuated by a corresponding number of control electro-magnets for writing on a recording support symbols and characters in conformity with dot matrices. The writing ends of the wires are aligned along a single line, the slanting of which relative to the direction of movement of the carriage is variable. With the writing ends vertically aligned the height of the 18 wires is equal to that of two lines of writing, 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 a line at a time with high definition dot matrices.

摘要： A wire printing head of ballistic type comprises a front guide fixed to a carriage and in which the printing wires are mounted in an axially slidable manner. The electromagnets for actuating the wires have their respective cores mounted inside a tube of non-magnetic material. In order to obtain high heat dissipation, the electromagnet cores and windings are embedded in a resin block which fills the interior of the tube. The exterior of the tube is also provided with a set of cooling fins.The electromagnet armatures are mounted on a rear cover which is connected by a screw to a part of the front guide, which in its turn is housed in a compartment in the resin block. Shims are disposed between the front guide and group of electromagnets, and their number can be varied in order to modify the distance of the ends of the printing wires from the platen.

摘要： A wire printing device comprises a frame removably mounted on a carriage which can move parallely to a platen. On the frame is removably mounted a guide block of resin material which guides a plurality of printing wires individually actuatable by a plurality of electromagnets, mounted on the frame. For an easy assembly of the printing device, a terminal guide is removably mounted on the frame for guiding the printing wires in proximity of the platen. Moreover, between the terminal guide and the guide block, a lubricating pad is disposed at contact with the printing wires and an oil container, mounted on the guide block, is connected through a wick to the pad for holding it constantly impregnated.

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 cartridge for an inked ribbon for printing machines, in particular wire printers, comprises a container and a pair of rollers for the feeding of the ribbon. The container comprises a storage zone, in which an inked ribbon is disposed in loops and is distributed at random, and a guide zone which surrounds the printing head of the machine. The guide zone comprises a series of ribs which twists a section of the inked ribbon through 180.degree. to form a Mobius loop. The rollers are free to move radially in corresponding seats of the container and are able to engage a pair of pins of the machine. One pin is a motor pin and rotates one of the rollers, and the other pin is a pressure pin which engages the other roller and is urged by a spring against the motor pin. The pressure pin causes the ribbon to be nipped between the two rollers to be fed by the motor pin.
