    • For compensating for the lateral displacement of the ribbon (4) during the print operation in impact printers with revolving type carriers (9), an inclined pivotable roller (1) is used which is taken along by contacting the moving ribbon. This roller has a pivot (10) with a free end pivotable between two stops (11,12). If there is no lateral ribbon displacement to be compensated for, the pivotable roller is arrested in its respective current position and thus prevented from rotating. In the event of a ribbon displacement (LS), the pivotable roller rotating about its axis exerts a force component (LO) on the ribbon, counteracting the lateral displacement (LS).
    • 为了补偿在具有旋转式载体(9)的冲击式打印机中打印操作期间色带(4)的横向位移,使用倾斜的可旋转辊(1),该倾斜的可旋转辊(1)通过接触移动的色带而被吸收。 该辊具有枢轴(10),其具有可在两个止挡(11,12)之间枢转的自由端。 如果没有要补偿的侧向带位移,则可枢转辊被阻止在其相应的当前位置,从而防止其旋转。 在色带位移(LS)的情况下,围绕其轴线旋转的可枢转辊在带上施加力分量(LO),抵消横向位移(LS)。
