    摘要： An impact printhead includes impact wires (2) loosely held in a guide and driven to print. The printhead includes individual holes through which corresponding wires extend, and elongated holes (23a, 23b) formed in the guide for guiding the wires. The elongated hole includes a concave wall (24b) and a convex wall (24a) opposing each other. The wires are slidable on the convex wall. When the wires are not driven to print, the wires are at rest in pressure contact with the convex wall. Grooves (35) may be formed in place of the elongated holes, and have second walls (33a) . The second wall lies substantially in a curved plane in which a first wall lies to define the individual hole. The wire is guided by the hole and groove. When the wire is not driven to print, the wire is at rest in pressure contact with the first and second walls.

    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： The printing head is of the type in which the tips of the needles are guided in two parallel rows by a pair of matrices (7, 8) disposed side by side and carried, a first by a support fixed to the printing body and a second by a support movable on the printing body so as to move the second matrix parallel to the first from a position in which the tips of the needles in the two rows are at the same heights (high-speed printing) to one in which the tips of the needles in one row are located at the heights of the spaces between the tips of the needles in the other row (high-definition printing); the movable support is fixed to the printing body by a parallelogram structure in which two parallel sides are constituted by the support (12) and the body (2) and the other two sides by resiliently-deformable members (20, 21); pre-loaded, resilient biasing means (200) keep the movable support against a first abutment (22) and an electromagnetic actuator (23), when operated, moves the movable support into contact with a second abutment (24).
