    • A print head assembly and a printer using the same are disclosed. The print head assembly includes: a bracket, a print head and an elastic element. The bracket includes a first bracket body having a cavity and a lid covered on the opening of the cavity. A window is opened on the first bracket body. The print head is accommodated in the cavity of the first bracket body and hinged to the first bracket body via a first rotary shaft. The surface of a heating element of the print head is matched with the window and faces an outside paper pressing roller. The elastic element biases towards the print head so as to make the surface of the heating element of the print head have a tendency to extend outside the window. The print head assembly is capable of being detached as a whole, thus the requirements of performing single-sided printing and duplex printing in the same printer is achieved.
    • 公开了一种打印头组件和使用该打印头组件的打印机。 打印头组件包括:支架,打印头和弹性元件。 支架包括具有空腔的盖的第一支架体和覆盖在空腔的开口上的盖子。 在第一支架主体上打开一个窗口。 打印头容纳在第一托架体的空腔中,并通过第一旋转轴铰接到第一托架体上。 打印头的加热元件的表面与窗口匹配,并面向外部的压纸辊。 弹性元件朝向打印头偏压,使得打印头的加热元件的表面具有延伸到窗外的趋势。 打印头组件能够整体脱离,从而实现了在同一台打印机中执行单面打印和双面打印的要求。
