PURPOSE:To fix the forward end of a tape tightly by arranging two pins in the inside space of a tape reel hub, and fixing the tape forward end to the two pins and then winding it around the tape wind surface of the hub through the slit of the hub. CONSTITUTION:In cylindrical space formed in the hub 2, two pins 3 and 4 projecting from the internal surface of a flange part 1 are formed. In this case, the pins are so arranged that the line connecting the slit 2a of the hub 2 and pin 3 and the line connecting the pins 3 and 4 cross each other at an acute angle. The forward end of the tape 5 is wound around the pins 3 and 4 in an 8 shape and led out of the slit 2a surrounding the outer circumferences of the pins 3 and 4 to be wound around the tape wind surface of the hub 2. Consequently, the friction of the tape is increased without requiring a tape retaining piece, and the tape never comes out. |
