Abstract: A printer for digital printing in which ink is deposited in metered amounts on a substrate. The printer includes a wheel rotatable by a shaft of a motor, an idler disposed in a paint reservoir, and a segment of wire disposed around the wheel and the idler. A computer controls movement of the wire by controlling the rotation of the wheel. As the motor rotates the wheel, ink contained within the paint reservoir coats the wire and is drawn by the wire in front of an air stream, which pulls the ink from the wire and carries it toward the substrate. The wire has features to increase a solution volume of the ink on the wire. The ink is applied to the substrate in vector mode to form well defined fine lines an image and a raster mode to form wider lines less well defined than the fine lines.

Abstract: In order to obtain joining force endurable for high-speed printing and realize an enhancement in magnetic characteristic, a plate-like arm for supporting a printing wire is laminated with a magnetic circuit forming member that is composed by laminating plural plates for forming a magnetic circuit, wherein a weld zone is formed on the laminated surface of the arm and plates with laser beam irradiation for fixing the arm and the magnetic circuit forming member with the weld zone.

Abstract: A wire dot printer head of the present invention has an armature that has an arm supporting a printing wire and pivotably provided at the position opposite to the core, and a coil spring that one end comes in contact with the arm for urging the armature in the direction away from the core, wherein the one end of the coil spring supported by the supporting member is brought into contact with the armature to apply return force to the armature. In order to prevent the breakdown of the armature due to a contact of the coil spring and to realize a stabilized urging operation of the coil spring, a winding end of the coil spring at the one end is located at the position inside of the coil spring and nearer to the supporting member from the contact position where the coil spring comes in contact with the armature.

Abstract: A system for depositing a material is described. The system uses at least one cantilever, and more typically a plurality of cantilever to transfer small amounts of material from a source of material to a substrate surface. One application for the system is a printing system in which the material is an ink and the substrate is a sheet of paper. By repeating this process, the cantilever places many units of ink to form the pixels in an image.

Abstract: An impact printer with a hammerbank having print hammers retained by a permanent magnet for impacting a print ribbon, and a mechanical driver for moving the hammerbank across print media. First and second coils for each hammer are wrapped around first and second pole pieces, one of which is asymmetrical to the other pole piece. One of the pole pieces can have a generally elongated longitudinal form with the coil wound around the longitudinal form and the other can have a generally arcuate form, with the coil wrapped on a portion between the ends thereof. The coil wrapped around the arcuately formed pole piece is thicker than the coil wrapped around the longitudinal pole piece. 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.

Abstract: A wire dot printer head of the present invention is provided with an abrasion preventive member in a yoke. The abrasion preventive member encloses the outer periphery of the armature support shafts. The yoke, together with an armature spacer having a plurality of cutouts for holding the armature support shafts, holds the armature support shafts. The armature support shafts do not directly contact the yoke because of the use of the abrasion preventive member. It is therefore possible to restrain abrasion of the yoke surface and accordingly to prevent deterioration in printing quality.

Abstract: A pin holder for a microarraying apparatus comprising at least one group of bodies of circular cross-section packed together to form a network of pathways in gaps between the bodies; and an array of pins slidably arranged in the pathways. The pins are held in parallel to each other automatically as a result of the self organized packing of the circular cross-section bodies, which may be spheres, for example ball bearings, or cylindrical, for example needle roller bearings. The pin holder provides for very accurate parallel alignment of the pins, low pin friction, as well as low cost and complexity of manufacture.

The printing head 3 is a dot impact type printing head having a plurality of printing wires caused to project selectively to form letters, and a recording medium 6 is conveyed between the platen 2 and the printing head 3 to have printing made thereon by the printing head 3. A protective film 8 is employed between the printing head 3 and the recording medium 6.

Abstract: In a wire dot printer head of the present invention, an armature is formed by coupling a magnetic circuit formation member having a supported piece with one end inserted into a cavity formed on a surface of a yoke to an arm coupled to a wire. The supported piece of the armature is rotatably supported by a support point, thereby a side surface of the cavity and a side surface of the supported piece, and a bottom surface of the cavity and an end surface of the supported piece can be set in the proximity. Accordingly, magnetic resistance between the magnetic circuit formation member and the yoke can be reduced.
