DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive tape cutter, such as a cellophane tape cutter, which can easily cut an adhesive tape, such as a cellophane tape.

[0002]

2. Description of the Related Art Adhesive tapes such as cellophane tapes used for attaching paper pieces or the like to office machines include, for example, an adhesive material on one or both sides of a band-shaped flexible sheet such as a band-shaped cellophane or a band-shaped nonwoven fabric. It is sold in a wound state in which the coated material is wound around a cylinder. Then, when using this adhesive tape, a desired length is peeled off from the wound state and cut. Various cutting methods, such as using scissors, are used as a means for cutting the adhesive tape. In general, a dedicated adhesive tape cutter is used.

As shown in FIG. 7, a conventional adhesive tape cutter 1 such as a cellophane tape cutter is provided with a pulley 4 rotatably supported on a shaft support 3 erected from a base surface 2.
An adhesive tape wound body 5 formed in a cylindrical wound state is attached to the pulley 4, and the adhesive tape 6 peeled off and pulled out from this is adhered to a tape receiving stand 7 fixed to the base surface 2. And temporarily fixed. The surface of the tape receiver 7 is horizontal like the surface of the adhesive tape 6 pulled out. 8 is a blade for cutting the adhesive tape 6,
The adhesive tape 6 is arranged parallel to the width direction.
When cutting the adhesive tape 6 from this conventional adhesive tape cutter 1, first remove the adhesive tape 6 from the tape receiving base 7, peel it off, draw it out, and temporarily determine the cutting length,
The adhesive tape 6 is temporarily fixed and stabilized by attaching the vicinity of the cutting position to the tape receiving base 7.
Is pulled down in the direction of the arrow, and the adhesive tape 6 is cut by applying the adhesive tape 6 to the blade 8.

The blade 8 of the conventional adhesive tape cutter 1
Are arranged parallel to the width direction of the adhesive tape 6 as described above, so that the adhesive tape 6 comes into contact with the entire width of the blade 8 when cutting. If the entire width of the tape is to be cut at a stretch, the entire width of the adhesive tape is cut by the blade 8 of the tape cutter at a time, requiring a relatively large force. When the adhesive tape 6 is not stuck to the tape receiving base 6 properly, when the adhesive tape 6 is forcibly applied to cut the adhesive tape 6, the adhesive slips on the tape receiving base 7 and the blade 8, and the adhesive tape 6 Not only will not be cut,
This causes a disadvantage that a stripe pattern is formed along the blade 8. Further, when the adhesive tape 6 slides on the tape receiving base 7 and the blade 8, the adhesive of the adhesive tape 6 adheres to the tape receiving base 7 and the blade 8, and dust and the like further adhere to the adhesive. There is a disadvantage that the dust adheres to the adhesive surface of the adhesive tape 6 to be cut thereafter. Further, as a result, there are also disadvantages such as filthiness and weakening of the adhesive force of the adhesive tape 6.

[0005] In order to cut the adhesive tape successfully,
At the time of cutting, the adhesive tape 6 may be slightly twisted. In this case, since the adhesive tape 6 is cut while being inclined with respect to the blade, there is a problem that the cut adhesive tape is twisted and the adhesive surfaces of the adhesive tape are bonded to each other. When such inconvenience occurs, it is necessary to pull out the adhesive tape again and cut it, so that there is much waste in time and economy, especially when the length of the cut tape is long, this inconvenience is remarkable. is there.

When the adhesive force of the adhesive tape 6 is strong,
When this is peeled off, the adhesive tape 6 is not necessarily pulled out in parallel as shown in FIG. 7, but is drawn out at an angle α with respect to the horizontal plane as shown in FIG. Also, the state shown in FIG. 8 occurs when the amount of winding of the adhesive tape 6 decreases. In such a case, since the adhesive tape 6 comes into contact only with the corner of the tape holder 7, the temporary fixing state with the tape holder 7 becomes more unstable.

[0007]
