Tape transporting apparatus including a tape guide with variable restricting force regions, each used depending upon the amount of tape tension

摘要

A tape transporting apparatus comprising a detecting device for detecting the winding diameter of a reel or the travelling state of tape, and a height variable device for varying the tape restricting height of a tape guide depending on the output of the detecting device, in which the tape restricting height is varied when the tape is deformed when the winding diameter becomes small and the tape tension becomes large, thereby preventing tape damage.
