    • A spool for a reversible-type correction tape assembly, in which an improved fastening means is provided between the cap and the spool shaft. The spool shaft is designed to hold a ribbon-winding core so that the winding core is slideable in an axial direction of the spool shaft but is not rotatable relative to the shaft. The cap is detachably mounted on the top portion of the spool shaft so that the winding core does not slip off of the spool shaft. The spool shaft is provided with a male thread on a peripheral portion which is an extension above the winding core when the latter is engaged on the spool shaft. The cap is provided with a cylindrical bore having a seat portion and an inner peripheral surface provided with a female thread capable of engaging the male thread of the shaft, and the spool shaft has a transverse projection on the head surface thereof designed to press into the seat portion of the cap when the cap is screwed onto the shaft extension, to provide an improved fastening means, the material of the seat portion being softer than the material of the projection. The cap can be easily detached and can be securely fastened against loosening during use.
    • 一种用于可逆型校正带组件的卷轴,其中在盖和卷轴之间提供改进的紧固装置。 卷筒轴被设计成夹持色带卷芯,使得卷芯在卷筒轴的轴向方向上可滑动,但不能相对于轴旋转。 盖可拆卸地安装在卷轴的顶部,使得卷芯不会从卷筒轴滑落。 卷筒轴在周边部分上设置有阳螺纹,外周部分是卷绕芯上方的延伸部,当卷绕轴接合在卷轴上时。 盖具有圆柱形孔,其具有座部和内周表面,内周表面设置有能够接合轴的阳螺纹的内螺纹,并且卷轴在其头表面上具有横向突出部,其设计成压入 当帽被旋拧到轴延伸部上时,帽的座部分,以提供改进的紧固装置,座部的材料比突起的材料更软。 盖可以容易地分离,并且在使用过程中可以牢固地固定在松动状态。
