2. Description of the Related Art An adhesive tape sticking device represented by cellophane tape is generally of a stationary type. For example, as shown in FIG. 11, the main body 101 has a twisted portion 105 between the tape holding portion 102 and the blade portion 103 that stretches the tape 104, and a finger is inserted into the twisted portion 105. ,
By pulling the picked tape 104, the tape 104 with the main body 101 placed on a desk or the like can be pulled out. On the other hand, there are some that are small in size and can be held and used by hand. For example, as shown in FIG. 12, which is called a portable type in contrast to the above, the main body 101 is held by one hand and the tape 10 is held by the other hand.
4 is pulled out, and the tip of the pulled-out tape 104 is stuck to a paper or the like to gradually lengthen the sticking area, and if necessary, be careful not to peel it off, and move the gripped main body 101 to further pull out the tape 104. , The operation of cutting the tape 104 after attaching most of it.

[0003]

In the former case of the above-mentioned prior art, fingerprint-like dirt remains on the adhesive surface of the tape 104, and the adhesive strength is apt to be insufficient due to hand marks. In addition, the tape 4 itself, which has been severely cut before being attached to paper or film, may self-adhere by a slight wind or something. Many of us will have many times experience that the adhesive surfaces stick to each other and feel frustrating to peel them off, and eventually have to throw away the cut tape 104. Further, there is a problem that after the tape 104 is attached to a paper or the like, the tape 104 becomes dirty or the paper or the like is twisted to cause wrinkles. Further, in the latter case, the continuity of the operation of pulling out the tape 104 and the operation of adhering the tape 104 is higher than that in the case of using the above-mentioned stationary type, so that the drawback of the self-adhesion of the tape 104 itself is particularly sufficient. Can be suppressed. But with your fingers tape 10
Although the necessity of picking 4 is reduced, it remains, so that the contamination of the adhesive surface of the tape 104 and the reduction of the adhesive force cannot be sufficiently suppressed. Further, there is a problem in that wrinkles are not a little generated after being attached to paper or the like.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems and not only can sufficiently eliminate the self-adhesion of the cutting tape before sticking it on paper or the like, but also it is necessary to pick it with a finger to pull out the tape. To prevent the tape from sticking to the surface of the tape and to prevent the tape from sticking to the desired length. A tape capable of holding a wound adhesive tape for the purpose of providing an adhesive tape adhering / cutting device capable of adhering a tape to a tape and easily cutting the tape without necessarily changing the gripping angle of the main body. In an adhesive tape sticking and cutting device having a main body having a holding portion and a blade portion capable of cutting the pulled-out tape, the main body having a size that can be held in a hand, a tape is drawn at the tip side of the tape. Has a cutting portion at the tip provided with a tape pressing portion capable of pressing the tape from the back side to be bonded kimono flop, it said tape pressing portion, tape within the body
The tape holder is constructed so as to be pulled out by twisting it by 90 °, and further provided with a rotation support portion capable of contacting the adherend with the tape pressing portion elastically displaced. The first gist is that the elastic displacement of the blade portion and the tape pressing portion can be released by rotating the main body by a predetermined angle from the state where the tape is in contact with the adhered object, and Behind the rotation support part, a contact support part capable of contacting the adherend with the rotation support part in a state where the blade part and the tape pressing part are elastically displaced is provided. The second gist is that both of the contact supporting portions come into contact with the adherend.

EXAMPLE The main body 1 is in the shape of a flat container as a whole. It is composed of an upper lid body 12 and a lower lid body 13 and contains a tape 4 therein. However, it may have the tape holding portion 2 that exposes the winding portion of the tape 4. Tape pressing part 6
Is provided on the tape pressing member 7 which is separate from the main body 1.
The tape pressing member 7 is a fitting fixing portion 14, 1 for the main body 1.
5 is provided on both sides (see FIGS. 1 and 6), and it does not serve as a sliding member, but has some oscillating property due to material elasticity. In particular, in order to suppress the variation in the pressing force when the tape 4 is attached, the tape pressing portion 6 is provided with a thinness capable of exhibiting an appropriate elasticity together with the pressing force. Further, the tape pressing member 7 is adapted to pull out the tape 4 by twisting the tape 4 in the main body 1 by 90 °. Furthermore,
A blade portion 3 for cutting the tape 4 is also provided on a blade member 17 which is separate from the main body 1, and the blade member 17 is a tape pressing member 7.
Has slidability with respect to. Further, the blade member 17 has a shaft support 35.
The tape 33 is connected to the tape pressing member 7 by the spring 33 attached to. Then, the tape pressing member 7 is fixed to the main body 1 at the fitting fixing portions 14 and 15. Therefore, when the tape protection portion 10 is brought into contact with an adherend such as paper, the blade member 17 elastically swings and slides due to the reaction of the force, and the tape pressing portion 6 also swings. . This swingability is larger than the swingability of the tape pressing member 7 described above. Although the blade portion 3 of the blade member 17 is inclined (FIG. 7), it shows one means for reducing the tape cutting force.

The winding portion of the tape 4 is fitted on the shaft member 28, and the shaft member 28 is provided with the shaft support portion 29 provided on the upper lid 12.
It is rotatably supported on. The shaft member 28 is attached to the main body 1 (shaft support 29) at a portion different from the central portion. In addition, the arm 1 extending behind the blade member 17
9 is connected by a connecting pin 37 at a position (connecting portion 28a) offset from the peripheral edge of the shaft member 28. By connecting the arm 19 to the shaft member 28 which is rotatably and oscillatably arranged at an eccentric position, the swing of the arm 19 which is interlocked with the sliding movement of the blade member 17 is further interlocked with the rotation of the shaft member 28. It has become. Reference numeral 40 denotes a wall thickness changing portion provided so that the swingability of the blade member 17 is not transmitted to the arm 19. Reference numeral 41 denotes a holding portion of the tape 4 provided on the tape pressing member 7. It shows an example in which the movement guide of the tape 4 is appropriately provided on the tape pressing member 7.

That is, when the blade member 17 is moved upward in the drawing, the shaft member 28 is rotated clockwise by a predetermined angle to loosen the tape 4 to finish pulling out the tape 4, and then the blade member 17 is moved downward in the drawing. At this time, since the holding piece portion 26 and the holding piece receiving portion 27 are holding the tape 4 again, the tape 4 is held.
The shaft member 28 rotates counterclockwise without retracting the tip of the shaft. It feels like you try it out,
It seems that at the initial stage of pulling out the tape 4, it is necessary to pull the tape 4 with a stronger force than in the subsequent pulling process.
Moreover, the area of the tape 4 that can be first applied to the adherend is by no means large. Therefore, in some cases, even if a force is applied to pull out the tape 4, only the portion of the tape 4 that is first attached may be pulled and peeled off. However, in the case of this example, since the tape 4 can be loosened at the initial stage of pulling out the tape 4, such a concern can be sufficiently reduced.

As described above, the elastic action of the spring 33 will be described in detail. The blade member 17 and the tape pressing member 7 are urged by the spring 33 so as to stick them to each other. Due to this urging force, the tape pressing member 7 and the lower lid 13 of the main body 1 come into contact with each other on a part of the wall surface. Are added together. A holding piece portion 26 located behind the tape pressing portion 6 and a holding piece receiving portion 27 at a position corresponding to the holding piece portion 26. The holding piece portion 26 and the holding piece receiving portion 2
Reference numeral 7 forms a chuck body that holds the tape 4 from both sides. By this holding, the tip position of the tape 4 can be stabilized until the attachment of the tape 4 is started. The present invention can be used as a sticking / cutting device for a non-adhesive tape, but it is also suitable for use as a sticking / cutting device for an adhesive tape, where a holding piece receiving portion located on the sticky surface side of the tape 4 is used. Reference numeral 27 is provided as a plurality of protrusions in the figure so that the tape 4 can be easily moved when the tape 4 is attached. The idea is to bring the tape 4 into contact with the tape 4 in a wide area and a narrow area, but it may be possible to use a surface treatment to facilitate peeling. Needless to say, such a concept may be applied to the holding piece portion 26, since a tape having adhesive surfaces on both sides is used. Further, above the blade portion 3, the upper lid 1
An angular rotation support portion 49 is provided above the tip end portion of 2, and a contact support portion 50 is provided below the rotation support portion 49 of the upper lid 12 (see FIG. 4).

Next, a usage example and operation will be described. FIG. 8 shows a state in which the tape protector 10 has begun to contact the adherend. The tape pressing portion 6 is the tape 4 not shown.
Has already been pressed against the adherend. When a pressing force is further applied from this state, the contact support part 50 also comes into contact with the adherend. After that, even if the pressing force changes during the sticking operation of the tape 4, the contact support part 50 absorbs the change in the force applied to the tape protection part 10 and the tape pressing part 6. The tape 4 can be stuck with a sufficiently stable sticking force.
In addition, the tape 4 may be attached with the rotation supporting portion 49 floating from the adherend, but the tape 4 may be attached with the rotation supporting portion 49 also in contact with the adherend. You can also This means that it is possible to give the user the preferred gripping angle of the main body 1 when sticking the tape 4 without being aware of it.

After the tape 4 has been attached over the desired length in this manner, the tape 4 is cut. It is in the state shown in FIG. The body 1 does not have to be purposely floated. The main body 1 may be rotated while the rotation support portion 49 is in contact with the adherend. First, the tape pressing portion 6 floats to release the force for pressing the tape 4 against the adherend, and eventually the tape protection portion 10 also separates from the adherend. Regardless of the case where the main body 1 is rotated very slowly, when the tape protection portion 10 separates from the adherend, it moves with some momentum. The tape 4 can be quickly cut and the state shown in FIG. 10 is obtained. Therefore, the tape 4 can be cut more smoothly. It should be noted that in the illustrated example, the rotation support portion 49
The contact support portion 50 and the contact support portion 50 are provided at both corners of one straight side, but it is appropriate. Further, the rotation support portion 49 and the contact support portion 5
At least one of 0 may be provided on the lower lid 13. Although illustration is omitted, in addition to the above, various modifications can be made without departing from the gist of the present invention. For example, a peripheral wall portion of a rotatable roller may be used as the tape pressing portion 6, the holding piece receiving portion 27 may be displaced, or a cap structure for covering the blade portion 3 when not in use may be added.

In this embodiment, in order to simplify the assembly of the main body, the upper lid 12 and the lower lid 13 are fixed to each other by a pair of elastic members provided in the upper lid 12 with respect to the through hole 46 of the lower lid 13. The engaging protrusion 48 of the protrusion 47 is engaged (see FIG. 5). The upper lid 12 and the lower lid 13 can be separated by deforming the elastic protrusions 47 so that they approach each other with a fingertip or the like. Further, since the width of the projecting end portion of the elastic projection 47 is narrow, it is only necessary to press the elastic projection 47 in alignment with the through hole 46 when fixing. Further, in order to make it easy to check the remaining amount of the tape 4, the main body 1 is appropriately molded from a transparent material, and the internal transparency may be adjusted by, for example, making the surface satin or slightly coloring. . As an example, in this example, small rib forming regions 44 and 45 are provided to prevent slipping when gripped (see FIGS. 3 and 4), but this is also useful for adjusting transparency.
