    • A printer device having a detachable thermal head, the thermal head being precisely positioned relative to a platen, whereby the printer device is capable of printing characters or the like, of a stable quality, on printing paper having different thickness'. A head module of the printer an attachment member detachably attached to a main frame; a movable support member movable relative to the attachment member; and a thermal head fixedly supported by the movable support member. The movable support member is connected to the attachment member via a plurality of head springs, and has a head positioning protruding portion configured to engage with a head positioning recess portion of the attachment member. The recess portion is formed as a groove which is generally straight, whereby the movable support member and the thermal head 44 may be straightly displaced relative to the attachment member only in the extending direction of the groove.
    • 一种具有可拆卸热敏头的打印机装置,热敏打印头相对于压板精确地定位,由此打印机装置能够在具有不同厚度的打印纸上打印质量稳定的字符等。 打印机的头模块,其可拆卸地附接到主框架上的附接构件; 相对于附接构件可移动的可移动支撑构件; 以及由所述可移动支撑构件固定地支撑的热敏头。 可移动支撑构件通过多个头弹簧连接到附接构件,并且具有构造成与附接构件的头部定位凹部接合的头部定位突出部分。 凹部形成为大致直的槽,由此,可移动支撑构件和热敏头44可以仅在凹槽的延伸方向上相对于附接构件直线移位。

    • A thermal printer including a thermal head; a platen cooperating with the thermal head to nip a printing sheet between the platen and the thermal head; an elastic member applying a biasing force to the thermal head in a direction to make contact with the platen; a frame supporting the thermal head in a shiftable manner and the platen in a detachable manner; and a biasing-force control mechanism controlling the biasing force of the elastic member. The biasing-force control mechanism operates to ensure, when the platen is mounted to the frame, a required contact pressure between the thermal head and the platen under the biasing force, and to prevent, when the platen is removed from the frame, the thermal head from being deformed due to the biasing force.
    • 一种热敏打印机,包括热敏头; 与所述热敏头组合的压板,以将压印板和所述热敏头之间的印刷纸张夹持; 弹性构件,在与所述压板接触的方向上向所述热敏头施加偏置力; 以可移动的方式支撑热敏头的框架和压板以可拆卸的方式支撑; 以及控制弹性构件的偏置力的偏置力控制机构。 偏置力控制机构的作用是确保当压板安装到框架上时,在偏压力下热敏头和压板之间所需的接触压力,并且当压板从框架移除时,防止热 头部由于偏置力而变形。

    • A disclosed printer includes a frame; a thermal head attached to the frame; a platen roller drive motor attached to the frame; a reduction gear train attached to the frame and configured to reduce the speed of rotation generated by the platen roller drive motor; and a platen roller detachably attached to the frame and configured to be driven by the platen roller drive motor via the reduction gear train and to feed paper while pressing the paper against the thermal head. The frame is produced by press-forming sheet metal and includes a horizontal plate part, a backboard part rising vertically from a back edge of the horizontal plate part, sideboard parts rising vertically from corresponding side edges of the horizontal plate part, and a projecting part protruding outward from an edge of one of the sideboard parts and forming a surrounding part of a gearbox.
