摘要： Disclosed is an impact dot head and an impact dot printer provided as not causing wire breakage by supporting a wire (8) performing a printing operation so as to be resiliently oscillatable in a printing digit direction even if the impact dot head starts printing from a position outside a printing sheet (19) due to erroneous setting of a printing area and therefore passes an end of the printing sheet while performing the printing operation.
The wires (8) are guided by a front end guide (6) disposed in a nose guide (18) in a nose (1). There are a number of ways disclosed of supporting the wires (8) in a resiliently oscillatable manner including a resiliently oscillatable nose guide, nose and a front end guide.

摘要： The present invention provides an impact dot printer free from the missing of dots. An impact dot printer for recording dots on a recording medium (21) comprises a printer wire (7) having a printer end, a guide member (8) for supporting the printing wire (7), an ink ribbon (20) which contains an ink composition comprising a dye and a solvent and is positioned between the printing end of the printing wire (7) and the recording medium (21). The printer also has a lubricant containg an oil component in the guide member (8) for permitting the printing wire (7) to be easily moved. The solubility of the solvent for the dye in the oil component of the lubricant is more than 400 g/100 g of oil.

摘要： An impact dot printer that includes: a plurality of print wires (15); a front end guide (17) having guide holes (21,23) for guiding the print wires to predetermined print positions; and a guide holding member (16) for holding the front end guide. Such impact dot printers receive lubricant (18) in a portion behind the front end guide (17) and performs the printing operation by biasing an ink ribbon (3) located between the front end guide and a print sheet (4) while projecting the print wires (15) onto the print sheet (4) at appropriate timings.
In such an impact dot printer, projections (20) are provided on a surface (17a) of the front end guide (17), the surface being on the print wire projecting side, and these projections form clearances between the surface of the front end guide (17a) and the ink ribbon (3), so that even if the lubricant (18) seeps from the guide holes (21,23), the lubricant does not come in direct contact with the ink ribbon, thus not ruining the ink ribbon to impair printing quality. A means (17b,22; 24,25; 26,27,31; 33-35; 36,37-42; 44) for preventing seepage of the lubricant through clearances between the front end guide and the guide holding member is also provided to further improve printing performance.

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： Bei einem Matrixnadeldruckkopf (1) mit verstellbarer Drucknadelführung (2) ist eine Drucknadelantriebsbaugruppe (3) und eine einem Druckwiderlager (4) zugewandte Drucknadelführungsbaugruppe (5) mit einem die Drucknadeln (7) führenden Gehäuse (8) vorgesehen. Im Bereich der Drucknadelführungsbaugruppe (5) befindet sich ein Elektrohubmagnet (9) mit Einstellschraube (12) für den Magnetkern (13), der zusammen mit einem Nadelführungsträger (15) einen einstellbaren Arbeitsluftspalt (14) bildet. Damit ist der Nadelführungsträger (15) zwischen zwei fest einstellbaren Positionen hin- und herbewegbar.
Um eine genau arbeitende Drucknadelführung zu schaffen, die auch für kürzere, biegunssteifere Drucknadeln geeignet ist, wird vorgeschlagen, daß der Elektrohubmagnet (9) mit seiner Spulenmittelachse (16) senkrecht zur in Druckrichtung der Drucknadeln (7) verlaufenden Mittelachse (17) des Matrixnadeldruckkopfes (1) angeordnet ist und daß der in einer Führung bewegbare Magnetkern (13) mit einem parallel verstellbaren Nadelführungsträger (15) verbunden ist.

摘要： A wire dot print head having long thin print wires (9) capable of axially advancing and withdrawing with respect to a print surface (7), and a wire driving device (10) connected to the proximal end of each of the print wires so as to drive the print wire to advance and withdraw axially. The wire dot print head includes a distal end guide (3) for guiding the distal end portions of the print wires so as to prevent them from shifting diametrically, and an intermediate guide (20) for guiding portions of the print wires which are in the vicinity of an antinode in the secondary natural vibration mode of the print wires so as to prevent the print wires from oscillating diametrically.
