When the slide groove 72 is shifted, the lock is released.

  Next, a procedure for using the handy tape cutter having the above-described configuration will be described.

  First, as shown in FIG. 3, the lock member 7 is set at a position straddling between the tape holder 1 and the cutter holder 2 so that the tape holder 1 cannot be rotated with respect to the cutter holder 2. Keep it locked.

  Further, the front end of the adhesive tape M drawn out from the tape winding N passes through the space 21 of the cutter holder 2 and is drawn out from the front surface side of the roller 25 to the sliding contact surface portion 24 side. .

  In this state, when the tip of the adhesive tape M is attached to the adherend surface P, the tape holder 1 is gripped and moved backward while lightly pressing the adhesive tape M with the sliding contact surface portion 24 on the cutter holder 2 side. The adhesive tape M is pulled out from the tape roll N and attached to the adherend surface P.

  After sticking the adhesive tape M of a predetermined length, if the lock member 7 is slid to the slide groove 72 side in the cutter holder 2 and the lock is released as shown in FIG. The rotation shift with respect to the cutter holder 2 of the tape holder 1 made into the fulcrum is attained.

  When the tape holder 1 is pivoted upward with the pivot pin 22 as a fulcrum, the cutter 4 is pressed downward by the cutter pressing portion 17 according to the lever principle, so that the cutter 3 is moved to the return spring member 4. The adhesive tape M is cut along a predetermined cutting line.

  When the upward rotation operation of the tape holder 1 is returned and the pressing operation by the cutter pressing portion 17 is released, the cutter 3 is raised by the spring force of the return spring 4 and returned to the original position. .

  Since the blade section 30 of the cutter 3 has a substantially U-shaped cross-sectional shape, the unused portion side cut end m in the cut adhesive tape M is a triangle protruding forward as shown in FIG. The pressed surface portion Ma remains.

  The blade 30 of the cutter 3 may have any cross-sectional shape as long as the pressed surface portion Ma protruding forward from the unused portion-side cut end m of the adhesive tape M can be formed. In addition, since it has a substantially square shape, it can be easily formed with a relatively simple structure, and the pressed surface portion Ma can be easily formed.

  Then, when the adhesive tape M drawn out from the tape wound body N is pasted on the new adherend surface P next time, the unused portion side cut end m of the adhesive tape M is already in the roller 25. It exists near the front side.

  At this time, if the tape pressing member 5 is pushed down, the tape pressing member 5 descends against the spring force of the return spring 6 and the pressed surface portion Ma of the adhesive tape M is covered as shown in FIG. Since it is pressed against the sticking surface P, when the tape holder 1 is gripped and retracted, the pull-out start on the unused MB side of the adhesive tape M is smoothly performed.

  Even if the cutter tool body 100 is not configured separately from the tape holder 1 and the cutter holder 2, the cutter 3 can perform operations such as cutting the adhesive tape M. However, as in this embodiment, the tape holder By connecting 1 to the cutter holder 2 so as to be rotatable, the cutter 3 can be easily moved down and moved by the turning operation of the tape holder 1 without having to manually move the cutter 3 downward. it can.
