  The tape cutter (50) is used by widening the angle between the cutter body (52) and the tape support arm (53) of the tape cutter (50), and opening the left support arm (59) and the right support arm (60). Attach the adhesive tape (49) to the paper tube hook (62), bring the end of the adhesive tape (49) to the front of the cutter blade (51), and the angle between the cutter body (52) and the tape support arm (53) The tape cutter (50) attached to the adhesive tape (49) becomes ready for use by narrowing.

  Pull out the end of the adhesive tape (49), insert a finger through the finger insertion slot (54), hold the adhesive tape (49) with the fingertip, and attach the adhesive surface of the adhesive tape (49) to the adhesive surface adhesion bar (57). The adhesive tape (49) is cut with the cutter blade (51).

  Since the mold of the present invention is inexpensive and has many functions, the industrial applicability seems to be high.
