Apparatus for winding up ribbon tape

Abstract

Abstract PURPOSE:To enable the accurate feed of an ink ribbon, by a method wherein a capstan is fabricated from a low hardness material while a pinch roller is excluded and a pass roller for regulating the wind-around amount of the ink ribbon to the capstan is provided. CONSTITUTION:A capstan 6 for positively feeding an ink ribbon 2 is fabricated from a low hardness material (pref., polyurethane rubber with Shore hardness A of about 20-30 deg.) and the ink ribbon 2 is wound-around the capstan 6 while a pinch roller is not used. The wound-around amount thereof is regulated so as to be sufficiently taken by the positional alteration of a pass roller 7 provided in the vicinity of the capstan 6. By this mechanism, the ink ribbon 2 is closely contacted with the outer periphery of the drive capstan 6 only by the tension of the ink ribbon 2 wound up by a spool 1 and transferred to a direction shown by an arrow A at a predetermined speed in a non-slip state by the drive capstan 6 to be wound up by the spool 1.
