109	Impact dot print head and printer including same	US760429	1991-09-16	US5322379A	1994-06-21	Takashi Takeuchi; Toshio Kuriyama
A printer including an impact dot print head for driving a plurality of print wires mounted on the cantilevered end of print levers is provided. The print head includes a stopper positioned to be impacted by a print lever returning from a print position to an at rest position before a plunger on the lever impacts the magnetic core. A spring mounted on the lever biases it towards the print position. Magnetic flux of a permanent magnet attracts the plunger to the non-print position. An electromagnetic coil is energized to cancel the magnetic attraction of the plunger to the core to drive the wire towards the print position.
110	Impact dot printer	US809894	1991-12-18	US5156469A	1992-10-20	Minoru Tanaka; Takashi Asada

The printing pins are positioned offset from one another in the shuttling direction to thus perform multiple dot line printings in the single shuttling motion. Each of the printing pins has a printing pin surface in abutment with the printing sheet through the ink ribbon. The printing pin surface has a polygonal shape defined by a combination of ridge lines. All ridge lines extend obliquely with respect to the shuttling direction for facilitating grinding of the printing pins.
112	Tandem station dot matrix printer	US385333	1989-07-24	US5013168A	1991-05-07	Katsuyoshi Yokota; Toshihiro Jingu; Kazunori Matsumoto
A dot matrix printer has two print head carriages, supported in parallel, and two print heads for printing a receipt and a journal in a tandem printing station arrangement. A drive cam with a rail on the periphery thereof is coupled to both carriages to drive the carriages in opposite directions upon rotation of the drive cam. The movement of one carriage acts as a balance to movement of the other carriage and thereby eliminates or substantially reduces vibration during printing operation.
113	Armature guide for wire dot print head	US405099	1989-09-08	US5002412A	1991-03-26	Isao Ohwada
A print head for use in a wire dot printer has a plurality of wires, an armature connected to each of the wires, a core of a magnetic circuit which is disposed in opposing relation to the armature, a resilient member for biasing the armature in a direction in which it is separated from the core, and a rear case disposed so as to cover the upper side of the armature. Each of the wires is driven by the action of the armature which is attracted toward the core when a coil wound on the core is energized. The print head is provided with an armature guide having a resilient stopper disposed between each armature and the rear case to support the armature against the biasing force from the resilient member. Thus, it is possible to support each armature inserted into the armature guide by means of the stopper even more stably during an assembling step carried out before the rear case is mounted. Accordingly, the assembling operation is simplified and facilitated.
114	Matrix pin print head of the hinged-clapper-armature construction	US387343	1989-07-28	US5000593A	1991-03-19	Bernd Gugel; Johann Stempfle
A clapper armature (3) is coordinated to each print pin (1) in a matrix pin print head of the clapper armature construction. A magnet yoke (10) is disposed opposite to each clapper armature (3), where one of the two magnet yoke arms (10a, 10b) is surrounded by an electromagnetic coil (2). The clapper armature (3) is supported between the magnet yoke (10) and an oppositely disposed support bearing (14) for tilting positions, which tilting positions correspond to the withdrawn and, respectively, front position of the print pin (1). The clapper armature (3) or the print pin (1) can be maintained in the withdrawn position in each case with a leg spring (16), where a first spring leg (16a) is supported against a print pin head or at the clapper armature (3), and where a second spring leg (16b) is supported on a print head case side (4). In order to furnish the clapper armature (3) or the print pin (1), respectively, with a more advantageous guide, the structure of the leg spring (16) has been improved in that all leg springs (16) are connected to each other and form a single-piece leg spring basket (17).
115	Arrangement of printing pins in a serial type dot printer	US240477	1988-09-06	US4936210A	1990-06-26	Makoto Ukai
In the present invention there is disclosed an improved serial type dot printer. According to the printer, the mutual magnetic interference between the magnetic circuits that are provided for each of the printing hammers to act as their respective driving sources, can be avoided by an appropriate choice of the distance between the printing pins, and at the same time, the power supply capacity can be reduced.
116	Shuttle for matrix printers	US777538	1985-09-18	US4727805A	1988-03-01	Josef Pichler; Karl Puchegger
A matrix line printer has an L-shaped shuttle for a series of electromagnetic actuators. Wires are provided running in an arc from the printer frame to the shuttle. Peojections on the shuttle engage eccentrically mounted rollers on the frame.
117	Dot printer	US686899	1984-12-27	US4643597A	1987-02-17	Tsutomu Matsui; Shinichiro Fujii; Mitsutoshi Kakishima
A dot printer wherein a bearing member is movably attached to each of two shafts disposed in parallel with a platen, and a plurality of electromagnets are secured to the bearing members together with a head which houses therein a plurality of needles driven by the electromagnets. In this arrangement, the necessity of employing a carrier can be eliminated to simplify the structure as well as to reduce both the dimensions and the weight of the whole while ensuring a high-speed printing operation with another advantage of facilitating the assembling process.
118	Adjustment of print position	US253875	1981-04-13	US4609294A	1986-09-02	Gunter Gomoll; Wolfgang Hendrischk
The platen roller in a matrix printer is mounted to the printer case so that stop plates of the mount define a representation of the disposition of the roller. A frame is provided to hold a guide rod on which rides a carriage, and the print head is secured to that carriage. Adjustable cams on the rod abut the stop plates when the frame is slid into the case to, thereby, establish the distance between head and platen. The frame carries also the head drive, its motor and the paper-feed motor, there being a key connection to the platen, maintaining a driving connection even for different cam adjustments and frame positions in the case.
119	Dot printer head with alternate magnetic flux paths	US654022	1984-09-25	US4597680A	1986-07-01	Takashi Norigoe; Kuniaki Ochiai
The printhead is constructed such that opposed surfaces of armatures are formed between the armatures adjacent to each other with small gap being left therebetween and cores opposed to each of the armatures are provided with alternative opposed magnetic fluxes. The armatures are supported in such a way that the guide holes formed in the middle of each armature are engaged with the fixed armature guides without interfering with their side surfaces, and thereby side magnetic paths of sufficient cross sectional area can be formed, and further their equivalent mass can be decreased and a high speed printing is enabled, and the armatures can be moved smoothly.
120	Matrix printer with magnetic head adjustment	US467574	1983-02-17	US4475826A	1984-10-09	Heinrich Durr; Lothar Haubrich; Wendelin Weber; Hermann Richter
A matrix printer comprising a printing head which is pivotable, under the influence of the braking effect of a magnetic field, about an axis which is perpendicular to the line direction and to the surface of the paper to be printed. The different printing positions of the printing head realized by said pivoting motion are utilized for printing characters with a comparatively good recognizability at a comparatively low printing speed or, as desired, for printing characters which are less rapidly recognizable at a comparatively high printing speed.Matrix printers of this kind are used, for example, in text editing systems.
