    • A thermal printer includes a body detachably including a platen roller unit having a platen roller, and a cover element movable relative to the body between an open position and a closed position, detachably including a thermal printhead unit. The cover element further includes a claw protruding backward, a stepped pin extending downward, including a step portion at a bottom end, and a stepped pin adjuster element. The thermal printhead unit includes an exothermic element array, a supported portion to be hooked on the claw, and a notch portion to be hooked on the step portion. The platen roller unit and the thermal printhead unit include respective positioning elements which engage with each other to restrict a relative movement of the exothermic element array and the platen roller while the cover element is in a closed position.
    • 热敏打印机包括可拆卸地包括具有压纸辊的压纸辊单元的主体,以及可拆卸地包括热打印头单元的能够相对于主体在打开位置和关闭位置之间移动的盖元件。 盖元件还包括向后突出的爪,向下延伸的阶梯销,在底端包括台阶部分和阶梯销调节元件。 热敏打印头单元包括放热元件阵列,待钩在爪上的支撑部分和钩在台阶部分上的切口部分。 压纸辊单元和热敏打印头单元包括各自的定位元件,它们彼此接合以限制放热元件阵列和压印辊在盖元件处于关闭位置时的相对运动。
