2. Description of the Related Art An adhesive tape sticking and cutting apparatus having a main body having a tape holding portion capable of holding a wound adhesive tape and a blade portion capable of cutting a drawn tape, and having a size which can be held by a hand. As an example,
The device described in Japanese Patent No. 42263 is known. FIG. 3 of the publication describes an embodiment in which the pressing portion 36 is made of a semi-circular elastic body. This is to ensure that the kraft tape adheres to the sticking surface even if the sticking surface has elasticity or unevenness. Because of the presence of the pressing portion 36, the kraft tape has the outlet outer edge 3
It is pulled out from the vicinity of 4 and attached in a curved state.

[0003]

However, in the above-mentioned prior art, the kraft tape has the outlet outer edge 3 as described above.
It is pulled out from the vicinity of 4 and attached in a curved state. Therefore, when the kraft tape is cut by the blade 37 and the case 32 is lifted after the attachment is completed, the kraft tape is changed from a curved state to a linear shape. In other words, it is in a state of hanging from the outlet outer edge 34 substantially right below. And if you try to attach it again in this state, the tip of the craft tape will be
It was hidden by 2 and the pressing portion 36, and its positioning was difficult. Occasionally, it started to be applied from an extra point or in an insufficient state. In addition,
At the time of sticking, it is possible to confirm the tip of the kraft tape by seeing it from the lateral direction of the case 32 and to start sticking. However, although it can be sticked almost exactly, it had to perform a troublesome operation.

EXAMPLES The main body 1 of the adhesive tape sticking and cutting device D 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. The tape pressing portion 6 is provided on the tape pressing member 7 which is separate from the main body 1. The tape pressing member 7 is the main body 1
The fitting fixing portions 14 and 15 for the fitting fixing portions 14 and 15 are provided on both sides (see FIG. 6) and are not sliding members.
With 15 as a fulcrum, it 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. The tape pressing portion 6 is curved upward with respect to the pressing surface. The tape pressing portion 6 may be formed of a semicircular rubber-like elastic body or the like and fixed to the tip of the tape pressing member 7 (see FIG. 7).

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 °. In addition,
The twisted tape 4 is linearly guided and pulled out by the U-shaped restraining portion 41 formed in the lead-out path 7 a of the tape pressing member 7. Further, the blade portion 3 for cutting the tape 4 is also provided on the blade member 17 which is separate from the main body 1.
Reference numeral 7 has slidability with respect to the tape pressing member 7. Also,
The blade member 17 is connected to the tape pressing member 7 by a torsion coil spring 33 attached to the shaft supporting portion 35.
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 protector 10 is brought into contact with an adherend such as paper, the blade member 17 elastically swings and slides due to the reaction of force.
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 oblique (see FIG. 3), it represents 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 has a 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. The arm 19 extending to the rear of the blade member 17 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 and the shaft member 28 which is arranged to be rotatable and swingable at an eccentric position, the sliding of the arm 19 which is interlocked with the sliding 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. Also,
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, and after the tape 4 is pulled out, the blade member 17 is moved downward in the drawing. Sometimes
Since the holding piece portion 26 and the holding piece receiving portion 27 hold the tape 4 again, the shaft member 28 rotates counterclockwise without retracting the leading end of the tape 4. It seems that you try it, but it seems that you need to pull the tape 4 with a stronger force in the initial stage of pulling out the tape 4 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 initially attached may be pulled and peeled off. However, in the present example, since the tape 4 can be loosened in the initial stage of drawing the tape 4, such a concern can be sufficiently reduced. Further, an angular rotation supporting portion 49 is provided upward at the tip of the lower lid body 13 above the blade portion 3, and the lower lid body 1 is provided.
A contact support portion 50 is provided below the rotation support portion 49 of No. 3.

By forming the tape pressing portion 6 into a thin-walled shape that is elastically deformable, even if the main body 1 is tilted at a right angle to the tape sticking direction, there is some unevenness on the sticking surface. Even if there is, it can be reliably attached. The tape pressing member 7 swings around the fitting fixing portions 14 and 15 as a fulcrum, and the tape pressing portion 6 is curved, so that the tape 1 is not restricted by various inclinations of the main body 1 depending on the usage state of the user. It can be attached reliably within a certain range of inclination. By the way, FIG. 8 shows a state of use when the inclination of the main body 1 is increased, and FIG. 10 shows a state of use when the inclination of the main body 1 is decreased. In any case, the tape 4 is surely attached to the surface to be attached. Further, since the tape 4 is linearly pulled out by the flat-plate-shaped tape pressing member 7, the sticking position (the tip of the tape) can be easily and accurately determined in a normal gripping state without any special operation. .

Next, a usage example 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 has already pressed the tape 4 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 as shown in FIG.
Further, when a pressing force is applied, the tape pressing member 7 elastically swings around the fitting fixing portion 14 (15) fixed to the main body 1 as a fulcrum. By this swinging motion, the holding piece 26
Then, the tape 4 held by the holding piece receiving portion 27 is released. The released tape 4 is linearly guided by the U-shaped restraining portion 41 formed in the lead-out path 7a of the tape pressing member 7, and is sequentially pressed from the main body 1 while being pressed by the tape pressing portion 6 by moving the main body 1. Be withdrawn. 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.

FIG. 10 shows a state in which the main body 1 is made to have a small inclination and the attachment is started. Thus, even if the inclination of the main body 1 changes each time it is used, or by the person who uses it, or when it changes during use, the pressing surface of the tape pressing portion 6 is further pressed by pressing as shown in FIG. Even if the contact portion with respect to changes, the tape 4 is stably pressed against the adherend (pressing surface) by the tape pressing portion 6 that curves and projects with respect to the pressing surface.

After the tape 4 has been attached over the desired length in this way, the tape 4 is cut. The body 1 does not have to be purposely floated. It suffices to rotate the main body 1 while keeping the rotation support portion 49 in contact with the adherend. First, the tape pressing portion 6 is lifted to release the force for pressing the tape 4 against the adherend, and then the tape. The protection part 10 also comes to separate from the adherend. Regardless of when the main body 1 is rotated very slowly, when the tape protection portion 10 separates from the adherend, the tape protection portion 10 moves with some momentum. This action causes tape 4
Is cut.
