摘要： An impact printer with a hammerbank having print hammers retained by a permanent magnet (82) for impacting a print ribbon, and a mechanical driver for moving the hammerbank across print media. First and second coils (98, 100) for each hammer are wrapped around first and second pole pieces (84, 86), one of which is asymmetrical to the other pole piece. One of the pole pieces (84) can have a generally elongated longitudinal form with the coil (98) wound around the longitudinal form. The other (86) can have a generally arcuate form, with the coil (100) wrapped on a portion between the ends thereof. The coil (100) wrapped around the arcuately formed pole piece (86) is thicker than the coil (98) wrapped along the longitudinal pole piece (84). The result is to provide pole pieces and coils for an impact printer having differing spatial relationships that can be staggered, or formed asymmetrically for more compact coil and pole piece placement to improve printer efficiency.

摘要： A printing system prints an image on a printing surface of a printing medium with a print head array having multiple columns of print heads, such as electro-mechanical actuator impact or non-impact print heads, ink-jet print heads, or bubble jet print heads, having varying positions in a vertical dimension in the print head array for printing in a corresponding printable column area of the image. The printing medium is moved relative to the print head array in the vertical dimension to cause selected non-contiguous portions of a defined printable segment along a horizontal dimension to be printed in each printable column area by the print heads having varying positions in the vertical dimension. Further movement in the vertical dimension causes selected non-contiguous portions of multiple defined printable segments to be printed. By combining the movement in the vertical dimension with movements of the print head array relative to the printing medium in the horizontal dimension of not more than the widest distance between any two consecutive non-contiguous portions, all defined printable segments contained in the image are printed.

摘要： The specification describes a low reluctance magnetic circuit for a dot matrix line printer for retaining hammersprings (16) by the magnetic circuit having pairs of pole pieces (44) formed of magnetically conductive sheets having a space for receipt of a permanent magnet (52). A coil (94,96) is wrapped around a portion of each of the pole pieces (44) between the magnet and the ends to provide a reverse magnetic field to the magnetic field provided by the permanent magnet (52). A magnetic shunt (54) is established between the pole pieces (44) to provide a greater magnetic effect. The pole pieces (44) are sized and plated at the ends, with a spaced wear bar (70) between them to provide improved performance and longer wear.

摘要： An impact dot printer with a print head having a ring-like arrangement of electromagnets (3, 3a, 10) in cooperation with a leaf spring (7) and a ring-shaped permanent magnet (4), a substantially ring-shaped magnetic member (13) is provided radially inside of the arrangement of electromagnets. If an electromagnet is energized, a leakage flux along a closed magnetic path including said magnetic member is established and substantially decreases a leakage flux through the cores of adjacent electromagnets, thus, avoiding the problem of magnetic interference between adjacent electromagents. The magnetic member is preferably provided with a gap giving it a C-shape, in order to avoid eddy currents to flow in the circumferential direction of said magnetic member.

摘要： Needle printing head of the permanent magnet type where the armatures (8, 15) of a plurality of printing actuators are attracted, in rest position, against the poles of a permanent magnet (1) and released in printing position by the "cancellation" of the magnetic flux caused by control windings (5) and where the impact of the armatures against the permanent magnet poles, when they return to the rest position is damped by a multilayer element interposed between armatures and magnetic poles and consisting in two thin sheets of magnetic steel (18, 19) between which a thin film (20) of resilient material, such as polyester is interposed.
