    • 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。
