Is curved so as to circulate around, and its tip is positioned near the outer peripheral surface of the fitting shaft 4.

When the operation amplification crank 5 is arranged in the internal space formed in the base portion 2, a part of the handle arm 8, the operation lever 9 and the upper part of the starting spring 10 are located above the base portion 2. It may be formed so as to protrude.

An outer peripheral piece 11 is formed inside the peripheral edge of the collar body 3, and a base is fixed to the outer peripheral piece 11.
The claw body 12 is formed, and the claw body 12 extends in parallel to the circumferential direction of the collar body 3 and has a protrusion 13 bulging outward in the circumferential direction at an intermediate portion thereof. A peeling blade 14 is formed which extends in the circumferential direction and has a tip portion appropriately approaching in the central axis direction of the circumference, and a finger hook portion is formed on the protruding portion 13, and the entire nail body or preferably the protruding portion 13 is formed. The base 14 is provided with elasticity substantially in the radial direction, and the blade 14 is always biased in the central axis direction when the adhesive tape winding body 23 is attached.

Reference numeral 15 denotes a tape mounting cylinder, in which the adhesive tape winding body 23 is formed as a tube width that can be fitted to the outside and the adhesive tape winding body 23 can be housed inside the outer peripheral piece 11 in the radial direction. Having an outer cylindrical portion 16 having a different outer diameter,
The outer peripheral surface of 6 is formed as a surface state capable of engaging with the inner peripheral surface of the core of the adhesive tape winding body 23 or press-contacting so as to increase the friction resistance, and is fitted inside the outer cylindrical portion 16 in the radial direction. Joint axis 4

Reference numeral 19 denotes a locking lid, which is formed with a flange for preventing slipping-off on one side of the protrusion fitted in the fitting shaft 4.

Reference numeral 20 denotes a tape holding lid, which is formed by integrally forming a collar body 22 facing the collar body 3 on one side of a cylindrical locking portion 21 fitted inside the outer cylindrical portion 16. ing.

The adhesive tape cutter of the present invention comprises a bearing 1
While the 7 is fitted onto the fitting shaft 4, the starter spring 10 is located on the outer peripheral portion of the ratchet 18, and the tip end of the starter spring 10 is engaged with the ratchet 18, so that the tape mounting cylinder 15 is attached to the main body portion. 1 and the locking lid 19 is fitted to the fitting shaft 4 to prevent the tape mounting cylinder 15 from slipping off by its collar, and further, the locking portion 21 is fitted to the outer cylindrical portion 16. In this way, the tape holding cylinder 20 is fitted into the tape mounting cylinder 15 to be configured,

When the operating lever 9 is moved so as to be pulled down to the front, the handle arm 8, the induction crank 7, the operation amplification crank 5, and the starting spring 10 move in conjunction with each other, and the starting spring 10
The tip end of the tape engages with the ratchet 18 and the tape mounting cylinder 15
When the operation lever 9 is returned in the opposite direction, the starter spring 10 slides on the ratchet 18 and the tape mounting cylinder 15 does not rotate, and the blade 14 of the claw body 12 interlocks with the operation lever 9 in the opposite direction. The direction, that is, the extending direction of the claw body 12 is set to be the anti-rotational direction of the tape mounting cylinder 15.

The claws 12 and especially the blades 14 are preferably formed as a body slightly narrower than the width of the adhesive-uncoated surface of the adhesive tape winding body 23 described later.

In addition, the adhesive tape winding body 23 is detached from the tape holding lid 20 and the claw body 12 is appropriately raised against its elasticity, and is tightly attached to the outside of the outer cylinder portion 16 of the tape mounting cylinder 15. Then, for example, it may be attached as shown in FIGS. 4 and 5, and then the claw body 12 may be returned to the original state and the tape holding lid 20 may be locked.

According to the above structure, the adhesive tape cutter of the present invention operates as follows. That is, by rotating the operation lever 9 by an appropriate angle and rotating the adhesive tape winding body 23,
Since the blade 14 portion at the tip of the claw body 12 is pressed against the surface of the adhesive tape winding body 23 and constantly presses in the axial direction, the blade 14
Is caught on the tape end of the adhesive tape winding body 23, and the tape end is raised. To use the adhesive tape, you just need to pick up the raised adhesive tape part with your fingers and peel it off.

An example of a structure particularly suitable as the adhesive tape winding body 23 is as follows. The adhesive tape roll 23 is
As shown in FIG. 3, an elongated adhesive tape 25 made of synthetic resin made of OPP or other appropriate material is wound around the core tube 24. The pressure-sensitive adhesive tape 25 is formed as a pressure-sensitive adhesive coated surface 26 to which a pressure-sensitive adhesive is applied except for a slight width portion on one end side of the roll width, and a slight portion of the pressure-sensitive adhesive uncoated surface 27 to a release surface having a release layer. The boundary 28 of both parts is continuous in the longitudinal direction. Slits (cuts) 29, which are parallel to each other in the winding direction at a desired interval and are cut in the winding direction in the radial direction, leave the end of the pressure-sensitive adhesive-uncoated surface 27 slightly and leave the wound body substantially. It is formed over the entire width. Note that the slit 29 may be formed to have the full width, and in that case, it is preferable that the end surface of the adhesive-uncoated surface 27 is adhered.

The adhesive tape roll 23 is composed of the adhesive tape 2
Since 5 is adhered by the adhesive in the wound state and the end of the adhesive-uncoated surface 27 is continuous in the longitudinal direction, even if the slit 29 is formed, it is in the wound state. Is maintained as it is, it does not lose its shape and part does not flicker. At the time of use, the adhesive-uncoated surface 27 portion between the adjacent slits 29, 29 is peeled off,
If this is picked up and peeled off, it is possible to obtain the unit adhesive tape 30 with the space between the adjacent slits 29, 29 as one unit.

When the adhesive tape winding body 23 is used by being attached to an adhesive tape cutter, the rotation of the adhesive tape winding body 23 causes the blade 14 at the tip of the claw body 12 as shown in FIGS.
However, since the surface of the pressure-sensitive adhesive tape 25 is always in contact with the surface of the pressure-sensitive adhesive-uncoated surface 27 with an appropriate elastic pressure P, the blade 1 moves as the blade rotates.
4 is caught in the slit 29 of the adhesive tape 25, and the layers are separated because the adhesive has not been applied.
7 easily penetrates into the back side of the adhesive 7 and, as a result, the adhesive-uncoated surface 2
7 is lifted above the claw body 12, and at the same time, the connection or adhesive portion of the end 27 of the non-adhesive coated surface is easily cut, and as shown in the figure, one unit adhesive tape is separated by each slit 29. The adhesive-uncoated surface 27 of 30 is easy to pick and stands up independently.

In this way, simply by pulling the operating lever 9,
Since the adhesive tape winding body 23 rotates and the adhesive-uncoated surfaces 27 of the plurality of unit adhesive tapes 30 are separated and automatically stand up in a row, the adhesive-coated surface 26 can be pulled by sequentially pulling them. By peeling, a plurality of unit adhesive tapes 30 can be sequentially obtained.

The adhesive tape cutter having the above structure is most preferably used by mounting the adhesive tape roll 23 having the above structure, but an adhesive tape roll having perforations is used instead of the slit 29. can do. In addition, a long adhesive tape winding body having no slits or perforations, or an adhesive tape winding body obtained by imparting tearing directionality to the width direction of the winding body, and further a long length having no adhesive-uncoated surface 27. Even when using a lengthy adhesive tape roll, the tape tip portion can be peeled off by the blade 14 of the claw body 12.

Although not shown in the drawing, the above-described configuration may be modified such that the tape holding lid 20 is locked to the fitting shaft 4. The base portion 2 and the collar body 3 can be integrally molded, but may be separately molded and fixedly fitted.

Further, in the case where the tape holding lid 20 is locked to the main body 1 side, the claw body 12 can be disposed close to the inside of the collar body 22. In any case, it is possible to directly fix the base portion of the pawl body 12 to the collar bodies 3 to 22. In addition, the nail body 12 is attached to the collar body 3,
It is also possible to form two pieces in the vicinity of each of 22 and to raise both end portions of the adhesive tape winding body 23.

Further, if the claw body 12 is formed so that the blade 14 portion is elastically approached in the axial direction,
The configuration is arbitrary. For example, the base of an independent pawl is pivotally attached to the collar body, and a spring attachment portion is formed between the pawl body and the collar body portion to interpose a spring, and the tip of the pawl body is always springed in the axial direction. It is also possible to adopt a structure in which the claw body is biased and the knob portion that can be pulled up against the spring is formed.

Further, the form of the base 2 is arbitrary,
It may be configured such that a pencil stand is continuously provided, or a storage portion such as a stapler is continuously provided. It is also effective to attach a weight in order to have stability in placement. Furthermore, each unit is not limited to the above configuration. It goes without saying that the wall thickness varies depending on the material, and if the wall thickness is thick, the form is thinned.

[0032]

According to the present invention, a plurality of desired unit adhesive tapes can be conveniently and plurally attached from the adhesive tape winding body by the attached nail body by only one-touch lever rotation operation of the attached adhesive tape winding body. It is possible to provide a pressure-sensitive adhesive tape cutter that can be continuously peeled while separating each of them. Since the cutter has an extremely simple structure, the mechanism has stability and is easy to operate.
