A cylindrical locking portion 29 that can be locked to is projectingly provided.

The adhesive tape cutter of the present invention comprises a starting shaft 11, a starting spring 13 and a rotation guide tube 12 of the main body 1.
Is inserted into the starting cylinder portion 21 of the tape mounting cylinder 18, the intermediate cylinder portion 5 and the groove cylinder portion 20 are fitted together, and then the shaft screw rotatable from the outside into the bearing hole 25 of the tape mounting cylinder 14. 30 is inserted, and the shaft screw 30 is fixed to the tip of the starting shaft 11 to combine the main body 1 and the tape mounting cylinder 18, and the tape holding lid 27 is fitted on the main body 1. At the same time

When the operating lever 14 is appropriately rotated in only one direction, the tip of the starting spring 13 is locked to the ratchet 22 to integrally rotate the tape mounting cylinder 18, and the operating lever 14 is rotated in the opposite direction. When you make it, the starting spring 13
Does not rotate the tape mounting cylinder 18 by sliding on the ratchet 22, and the direction of the blade 10 of the pawl 8, that is, the extending direction of the pawl 8 is
The tape mounting cylinder 18 is set so as to be in the opposite rotation direction.

The claws 8 and especially the blades 10 are preferably formed to be slightly narrower than the width of the adhesive-uncoated surface of the adhesive tape winding body 31 described later.

Further, the adhesive tape winding body 31 is temporarily mounted on the outside of the outer cylinder portion 19 of the tape mounting cylinder 18 by removing the tape holding lid 23 and appropriately raising the claw body 8 against its elasticity. Then, for example, it may be mounted as shown in FIG. 4, and then the claw body 8 may be returned to the original state and the tape holding lid 27 may be locked.

According to the above construction, the adhesive tape cutter of the present invention operates as follows. That is, when the operation lever 14 is rotated by an appropriate angle to rotate the adhesive tape winding body 31, the blade 10 at the tip of the claw body 8 is attached to the surface of the adhesive tape winding body 31.
Since the part is pressed against and constantly elastically pressed in the axial direction, blade 1
0 is caught on the tape end of the adhesive tape winding body 31, 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 31 is as follows. The adhesive tape roll 31 is
As shown in FIGS. 4 to 6, the synthetic resin long adhesive tape 33 made of OPP or other appropriate material is wound around the core tube 32. The pressure-sensitive adhesive tape 33 is formed as a pressure-sensitive adhesive-coated surface 34 on which a pressure-sensitive adhesive is applied except for a slight width portion on one end side of the roll and a pressure-sensitive adhesive-uncoated surface 35 or a release surface having a release layer on the above-mentioned slight portion. The boundary 36 of both parts is continuous in the longitudinal direction. A slit (cut) 37, which is parallel to the winding direction at a desired interval and is cut in the winding state in the radial direction, leaves the end of the pressure-sensitive adhesive-uncoated surface 35 slightly, and the slit 37 is substantially formed. It is formed over the entire width. In addition, the slit 37 may be formed in the full width, and in that case, it is preferable that the end surface of the adhesive-uncoated surface 35 is adhered.

The adhesive tape roll 31 is made up of the adhesive tape 3
Since 3 is adhered by the adhesive in the wound state and the end of the adhesive-uncoated surface 35 is continuous in the lengthwise direction, even if the slit 37 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 non-coated surface 35 portion between the adjacent slits 37, 37 is peeled off,
If this is picked up and peeled off, the unit adhesive tape 38 with one unit between the adjacent slits 37 can be obtained.

When the adhesive tape winding body 31 is used by being attached to the adhesive tape cutter, the blade 10 at the tip of the claw body 8 is rotated by the rotation of the adhesive tape winding body 31 as shown in FIGS.
However, since the surface of the adhesive tape 33 is always in contact with the surface of the adhesive tape 33 on which the adhesive is not applied with an appropriate elastic pressure P, the blade 1 is rotated as the blade 1 rotates.
0 is caught in the slit 37 of the adhesive tape 33, and the layers are separated because the adhesive is not applied.
5 easily enters the back side of the adhesive sheet 5, and as a result, the adhesive-uncoated surface 3
5 is lifted above the nail body 8, and at the same time, the connection or adhesive portion of the end of the non-adhesive surface 35 is easily cut off,
As shown in the figure, the adhesive-uncoated surface 35 of each unit adhesive tape 38 separated by each slit 37 is easy to pick and stands up independently.

In this way, simply by turning the operation lever 14, the adhesive tape winding body 31 rotates, and the adhesive-uncoated surfaces 35 of the plurality of unit adhesive tapes 38 are automatically separated in a row. Since the adhesive coating surface 34 is peeled off by pulling these in sequence, a plurality of unit adhesive tapes 3
8 can be obtained sequentially.

It is most preferable to use the pressure-sensitive adhesive tape cutter having the above-mentioned structure with the pressure-sensitive adhesive tape roll 31 having the above-mentioned structure, but use the pressure-sensitive adhesive tape roll having perforations instead of the slits 37. 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 35. Even when using a lengthy adhesive tape roll, the tape tip portion can be peeled off by the blade 10 of the claw body 8.

Although not shown in the drawing, the above-described structure may be modified such that the tape holding lid 27 is locked to the outer peripheral piece 6. The base portion 2 and the collar body 3 can be integrally molded, but may be separately molded and fixedly fitted.

Further, the claw body 8 can be arranged close to the inside of the collar body 3, and in this case, the base portion of the claw body 8 can be directly fixed to the collar body 3. It is also possible to form two claw bodies 8 in the vicinity of each of the collar bodies 3 and 28 so that both end portions of the adhesive tape winding body 31 are raised.

Further, the structure of the pawl 8 is also arbitrary as long as the blade 10 is formed so as to elastically approach in the axial direction. 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.

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.

[0036]

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.
