[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following, the same reference numerals in different drawings indicate parts with the same function, and duplicated explanations in each drawing will be omitted as appropriate.

[0010] In the present invention, "double-sided tape" refers to a tape having adhesive surfaces on both sides, one of which has a release paper attached.

[0011] Fig. 1 is an external view of the tape cutter for double-sided tape as seen from the right side of the tape cutting section 1b, and Fig. 2 is an external view as seen from the left side of the tape cutting section 1b. The tape cutter for double-sided tape is made up of the parts and structure shown in Figs. 1 to 7.

[0012] FIG. 1 shows an external view of a tape cutter for double-sided tape according to an embodiment of the present invention. The cutter base main body 1 is broadly divided into a tape placement section 1a at the rear and a tape cutting section 1b at the front. The tape cutting section 1b is provided with a guide support section 3b and a guide receiving section 3c for attaching a guide member 3a for slidably supporting the cutter section 2. A groove for clamping one end of the guide member 3a is provided at the top of the guide support section 3b, and the guide member 3a is rotatably supported by a bolt 1d and a nut 1e. In addition, a groove for clamping and holding the other end of the guide member 3a is provided at the top of the guide receiving section 3c, which holds the guide member when cutting the tape. The opening of this groove may be slightly larger than the bottom to facilitate insertion of the guide member 3a.

[0013] Figure 4 shows a view from below of the cutter unit 2. Inside the cutter unit 2, there is a perforated rotary blade 6 for cutting only the tape portion, and a rotary blade 7 for cutting the entire double-sided tape including the tape portion and the release paper, with a spacer 8 sandwiched between the two blades to separate them, and the two blades 6, 7 and the spacer 8 are rotatably fixed by bolts 2a and nuts 2b.

[0014] The tape shaft 4 is fixed to the cutter base main body 1 through the core of the cylindrically wound double-sided tape body 11. Figure 5B is a cross-sectional view of Figure 5A taken along line AA, as seen from the back of the double-sided tape tape cutter. A tape shaft fixing groove 1c is provided on the inside of the cutter base 1 to allow the tape shaft 4 to pass through. Figure 6 is an overall view of the tape shaft 4. Fixing protrusions 4a are provided on both ends of the tape shaft 4, and these protrusions are fitted into the tape shaft fixing groove 1c to fix the tape shaft 4. The tape shaft 4 is inserted from the top of the cutter base main body 1, and then moved toward the tape cutting section 1b and fixed to the cutter base 1. The tape shaft fixing groove 1c may be inclined from the top to the bottom so as to approach the tape cutting section 1b.

[0015] The tension rod 5 is a part that prevents the double-sided tape from sagging. The tape pulled out from the tape shaft passes under the first tension rod on the side closer to the tape mounting section 1a, and then passes over the second tension rod on the side closer to the tape cutting section 1b. This prevents the tape from sagging until it reaches the cutting section.

[0016] It is advisable to use a tension rod 5 that is Teflon-coated to prevent the tape from sticking to it. The rod itself may also be designed to be rotatable so that the tape can be pulled out smoothly.

[0017] FIG. 7 is a top view of the tape cutting section 1b. The perforation rotary blade groove 9 and the cutter blade groove 10 are provided on the top surface of the tape cutting section 1b so that the double-sided tape can be cut in a straight line when the cutter section 2 is moved and so that the blade can firmly bite into the tape. The perforation rotary blade groove 9 is located further from the tape placement section 1a than the cutter blade groove 10. The perforation rotary blade 6 is fitted into the perforation rotary blade groove 9, and the cutter blade 7 is fitted into the rotary blade groove 10 to form perforations in the double-sided tape and cut the double-sided tape, respectively. The cutter blade does not necessarily have to rotate, and may be a knife-like blade.

[0018] The tape portion of the double-sided tape that was cut off by the two blades remains on the surface of the tape cutting section 1b between the perforated rotary blade groove 9 and the cutter blade groove 10. This area must therefore be made rough so that the tape can easily stick to it and be peeled off.

[0019] How to use this tape cutter is shown in Figures 8A to 8D. First, a cylindrically wound double-sided tape body 11 threaded through a tape shaft 4 is set on the cutter base body 1, and the double-sided tape peeled off from the double-sided tape body 11 is passed up and down the tension rod 5 and carried to the tape cutting section 1b. When pulling out the double-sided tape, the guide member is lifted up so that the cutter section 2 does not get in the way (Figure 8A).

[0020] After the double-sided tape is pulled out and attached to the tape cutting section 1b, the cutter section 2 is lowered to a position where it comes into contact with the cutting section 1b, and the double-sided tape is fitted into the gap between the cutter section 2 and the tape cutting section 1b (Fig. 8B).Then, the cutter section is moved along the guide member to form a cutting line and perforations in the pulled-out double-sided tape.

[0021] After forming a cutting line and perforations in the double-sided tape, cutter part 2 is lifted (Fig. 8C). At the end of the double-sided tape above tape cutting part 1b, perforations and a cutting line are formed to form a mark for peeling the tape (the part of the cut end surface of the double-sided tape where there is no double-sided tape with an adhesive surface and only the release paper is exposed).

[0022] The double-sided tape of the portion to be cut is peeled from the cutting portion 1b from the cutting side up to the marked portion (perforated portion), and the tape is pulled toward you. Only the tape portion cuts at the marked portion and remains attached to the cut portion 1b (FIG. 8D). The double-sided tape thus separated is as shown in FIG. 9A, which is a top view, and FIG. 9B, which is a side view. At the end surface of the separated double-sided tape, tape portion 11b remains at the cutting portion 1b from the end surface of the double-sided tape to the marked portion (perforated portion). Therefore, this portion of the tape portion is cut off from the separated double-sided tape. Then, a claw portion 11c, without tape portion 11b, is formed on the release paper 11a from the end of the release paper 11a of the separated double-sided tape to the marked portion. When this separated double-sided tape is applied to a desired location, the remaining portion of the release paper is not attached, so this portion becomes the claw portion 11c, allowing the release paper to be peeled off.

[0023] By adjusting the diameter of the tape shaft, the present invention can be applied to double-sided tapes of various sizes, and because it has a certain width, it is also possible to store multiple rolls of double-sided tape in one tape cutter. [Industrial Applicability]

[0024] This invention makes it easier to remove double-sided tape by creating a claw on the release paper. It is also possible to store various sizes and numbers of double-sided tapes, which is expected to save storage space. Furthermore, the blade that cuts the tape is mostly enclosed within the cutter case, and is inserted into a groove when cutting, making the process safer. [Explanation of symbols]
