    摘要： A drive circuit for driving a wire dot print head including a driving coil (5), a lever (6) for causing a print wire (7) to strike a platen (16) under the action of the driving coil, a spring member (12) for urging the lever (6) to an initial position, and a damper member (13) for absorbing kinetic energy of the lever when it returns to the initial position, comprises a circuit (30, 32, 40, 50) for causing current to flow through the driving coil (5) when the lever (6) is returning to the initial position after having struck the platen (16) in the case where the temperature of the print head is outside a set temperature range. Thus, in operation, a braking force is applied to the lever (6) as it returns to the initial position.

    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.
