    • A media centering spindle assembly (10) with a spindle body (13) and a clutch drive assembly (60). The spindle body (13) includes a centering mechanism (39) such as a rack (40, 41) and pinion (42) or centering slat (115). The centering mechanism (39) is configured to center and retain a media roll (11), ribbon supply or the like along the spindle body (13) and includes at least one spring tab (47b). The spring tab (47b) is deflectable from an initial position to a second position below a surface of the spindle body (13) to allow the mounting of the media roll (11) or the like. The assembly may be further configured as rotatable about a longitudinal axis of the spindle body (13) with the clutch drive assembly (60) having a friction level adjustable by rotation of a clutch adjuster (85) about the longitudinal axis of the spindle body (13).
    • 一种具有主轴主体(13)和离合器驱动组件(60)的介质定心心轴组件(10)。 主轴体(13)包括定心机构(39),例如齿条(40,41)和小齿轮(42)或定中心板条(115)。 定心机构(39)构造成沿着主轴主体(13)中心并保持介质辊(11),色带供给等,并且包括至少一个弹簧片(47b)。 弹簧片(47b)可从主轴主体(13)的表面下方的初始位置偏转到第二位置,以允许安装介质辊(11)等。 该组件可以进一步构造为围绕主轴本体(13)的纵向轴线旋转,离合器驱动组件(60)具有可通过离合器调节器(85)围绕心轴主体的纵向轴线旋转而调节的摩擦级( 13)。
