It is rotatably mounted at an appropriate position below the tape pull-out portion 6. Further, a columnar or cylindrical pressing tool 7 is provided at an appropriate position at the upper end of the arm 5 so that the upper wall of the tape drawing portion 6 moves in an arc so that the peripheral wall comes into contact with or separates from the adhesive band 4, and the lower portion of the tape drawing portion 6 moves in an arc. A columnar or cylindrical guide 8 is rotatably mounted at an appropriate position above the arm 5 so that the peripheral wall is in contact with the tape at the center of the tape drawer 6. The arm 5 is set at a position inclined to the tape winding 12 side, and moves the arm 5 in the direction of the cutting blade 3. At that time, the guide 8 sticks to the tape, sends out the tape in the direction of the cutting blade 3, and the pressing tool 7 presses the resulting flexure 13 against the sticking band 4 to turn the end of the adhesive tape back. An adhesive part is created.

[0005]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 to FIG. 5 show a first embodiment of the present invention, and the structure is as follows. Body 1
In addition, the rod-shaped arm 5 makes a fan-shaped motion parallel to the tape withdrawing direction with respect to the horizontal plane on the tape cutter for the adhesive tape including the tape winding fixture 2, the cutting blade 3, and the adhesive band 4 provided near the cutting blade 3. The arm support shaft 9 provided by bending the lower end of the arm 5 is rotatably inserted into a perforated hole which is appropriately drilled at a position below the tape pull-out portion 6 of the main body 1 so as to be rotatable.
The arm 5 is constrained to the tape winding 12 side by a spring 10 of an appropriate strength which is fitted and attached. Further, a cylindrical pressing tool 7 is rotatably inserted into a shaft provided by appropriately bending the upper end of the arm 5 so that the upper portion of the arm 5 is bent so that the upper wall of the arm 5 is bent so as to make a circular motion above the tape pull-out portion 6 so that the peripheral wall comes into contact with and separates from the adhesive band 4. At the same time, a cylindrical guide 8 is rotatably mounted on a shaft protruding at an appropriate position above the arm 5 so that the tape moves in an arc below the tape pull-out portion 6 and the peripheral wall contacts the tape at the center of the tape pull-out portion 6. Things. The arm 5, the pressing tool 7, and the guide tool 8 are made of a strong material such as metal or plastic, and the arm 5 is provided with a lever 11.

Further, in practicing the present invention,
It is necessary to satisfy that the pressing tool 7 and the guide tool 8 do not directly contact the tape winding 12 and that the guide tool 8 does not hinder the contact of the pressing tool 7 with the adhesive band 4 by adjusting the shape and mounting position of the parts. There is.

Next, the tape winding 12 is mounted on the tape winding fixing device 2 so that the adhesive surface faces downward when the tape is pulled out in the direction of the cutting blade 3, and the pulled out tape is fixed to the pressing device 7 and the guide device 8. Then, the tape end is attached to the adhesive band 4.

When a non-adhesive portion is formed at the end of the tape by using the tape cutter with a folding mechanism, the lever 11 provided on the arm 5 is pressed down, and the pressing tool 7 and the guide 8 is moved in the direction of the cutting blade 3. At that time, the guide 8 comes in contact with the tape pull-out portion 6 and sticks it, and sends out the tape in the direction of the cutting blade 3 to form a tape bending 13 upward as shown in FIG. Further, the pressing tool 7 presses the flexure 13 against the adhesive band 4 to form a fold 14 at the end of the tape, resulting in a state as shown in FIG. When the hand is released from the lever 11, the arm 5 returns to the tape winding 12 side by the spring force as shown in FIG.
And is peeled off from the adhesive band 4.

When the tape is pulled out to an arbitrary length and cut, the tape is pulled out with the fold 14 sandwiched between fingers.
The rest is used in the same manner as a normal tape cutter, but the fold 14 at the end of the tape is completely folded when sandwiched between fingers to complete the non-adhesive portion.

In the above process, when the arm is released from the lever 11 and the arm 5 returns to the tape winding 12 side, the area of the adhesive band 4 has its function so that the tape is smoothly separated from the adhesive band 4. It has been reduced to the extent that there is no problem.

In the present invention, when the tape is sent out in the direction of the cutting blade 3 by the guide 8 and the tape bends downward, the non-adhesive portion cannot be formed. And by adjusting the tape withdrawal angle with the height of the cutting blade 3 mounting position. Further, the pressing tool 7 not only plays a role of pressing the tape bending 13 against the adhesive band 4, but also suppresses a position where the tape pull-out portion 6 branches off in the tape winding 12 when the tape is pulled out from being displaced upward. It also serves to keep the drawer angle constant, which also prevents the tape from sagging downward.

Further, in the embodiment shown in FIGS. 1 to 5, the pressing member 7 is rotatably fixed to the upper end of the arm 5. When acting to keep the withdrawal angle constant,
This has the effect of minimizing the hindrance to tape withdrawal.

According to the present invention, a non-adhesive portion cannot be formed unless the length of the flexure 13 formed by feeding the tape by the guide tool 8 is also appropriate. Also in this case, it is necessary to determine the contact position of the guide 8 in the tape pull-out portion 6 at an appropriate position by adjusting the shape of the component and the mounting position.

In the embodiment shown in FIGS. 1 to 5, the arm 5 is moved to the cutting blade 3 in the direction of the cutting edge 3 by the lever 11 at a mounting angle at which the lever 11 can be pushed down.
It is connected to and provided. By installing the arm 5 in this manner, when the tape cutter is a tabletop type, the non-adhesive portion can be created without falling over without holding the main body 1.

FIG. 6 shows a second embodiment of the present invention. In addition to the method of inserting and attaching the arm support shaft 9 for the spring 10, one end of the main body 1 as shown in FIG. The other end of the spring 10 fixed to the arm 5 may be provided by a method of fixing it to the upper part of the arm 5 or the like. It is also conceivable to use a plate-shaped arm or the like as shown in FIG. In the embodiment shown in the figure, two plate-shaped arms 5 are fixedly attached to both ends of an arm support shaft 9 which is rotatably inserted into a perforated hole which is appropriately drilled below the tape pull-out portion 6 of the main body 1. . Further, as the pressing tool 7 and the guide tool 8, a cylindrical body having a shaft protruding at both ends is used, and the shaft is rotatably inserted into a perforated hole continuously drilled at an appropriate position of the arm 5.

The tape cutter with a folding mechanism according to the present invention can be used as a normal tape cutter unless the arm 5 is used.

[0018]

Since the present invention has the above-described configuration,
The end of the adhesive tape can be efficiently folded back to create a non-adhesive portion by a simple operation without any trouble, and if the arm 5 is not used, it can be used as a normal tape cutter, so that it is convenient. is there.
