DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape cutter capable of forming a curled portion (non-adhesive portion) at one end of a winding tape.

[0002]

2. Description of the Related Art A tape cutter as shown in FIG. 9 is well known. The tape cutter includes a cutter base 31 that rotatably supports the winding tape 30, and a cutter blade 32 that is provided so as to project from the cutter base 31. On the other hand, in the manufacture of electronic devices, for example, electronic parts (for example, circuit boards) may be temporarily adhered to each other with a tape.

[0003]

In such a case, as shown in FIG.
If you cut the tape with a tape cutter like this and attach it to the circuit board, both ends of the tape will completely adhere to the circuit board, so when you peel off the tape later, raise one end of the tape with your nails etc. Need to be peeled off. For this reason, not only the tape peeling work is troublesome, but the circuit board is scratched by the nail, and the circuit pattern is short-circuited due to scratches, especially on a circuit board having a fine circuit pattern. Will cause a problem.

Such a problem is that there is a short time in daily life. For example, when using tape for packing nylon bags, plastic bags, etc., it is difficult to remove the tape when it is necessary to remove it later, because the adhesion between the tape and the nylon bag or vinyl bag is easy to get used to. Then, the nylon bag and the plastic bag will be torn. The same applies when the papers are adhered to each other with a tape.

Therefore, the present invention has been made in view of such problems, and an object of the present invention is to provide a tape cutter which is convenient for applications where it is necessary to remove the tape later.

[0006]

In order to achieve the above object, a tape cutter according to claim 1 of the present invention is provided with a cutter stand for rotatably supporting a winding tape, and the cutter stand is provided on the cutter stand. The tape positioning tool that positions the tape, the movable cutter blade whose blade edge projects from the tape positioning tool in the state of being adjacent to the tape positioning tool, and the cutter base that supports the cutter blade, and the cutter blade can move forward and backward with respect to the tape positioning tool. And a biasing member that is attached to the guide member and biases the cutter blade toward the tape positioning tool.

This tape cutter is used in the same manner as a normal tape cutter as shown in FIG. That is, when the tape is pulled out from the winding tape, the blade edge of the cutter blade is pulled as the tape is pulled out, and the blade (especially the blade edge) is displaced in the direction away from the tape positioning tool against the biasing force of the biasing member. To do. When the tape is pulled to some extent, the tape is cut by the cutter blade due to the force of the cutter blade that tries to return to the original position (position adjacent to the tape positioning tool) due to the restoring force of the biasing member. Then, since the cut end of the tape adheres to the cutting edge of the cutter blade and the tape adheres to the tape positioning tool, the tape portion from the tape positioning tool to the cutting edge loosens as the cutter blade returns to its original position. It will curl as it comes out. When the cutter blade completely returns to the original position, the tape portion becomes curled (folded in two).

Therefore, the next time the tape is cut, the tape may be pulled out in the same manner while holding the curled portion. Since the cut tape always has a curled portion (non-adhesive portion) formed at one end, it can be easily peeled off from the curled portion when it is necessary to peel off after adhering. The tape cutter according to claim 6 further comprises a cutter stand for rotatably supporting the winding tape, a tape positioning tool provided on the cutter stand for positioning the tape from the winding tape, and in a state of being adjacent to the tape positioning tool. A swingable tape drawer having a tip protruding from the tape positioning tool, a guide member supported by a cutter stand and capable of advancing and retracting the tape drawer with respect to the tape positioning tool, and a tape drawer attached to the guide member. A biasing member for biasing the tool toward the tape positioning tool and a cutter blade fixed to the cutter stand so that the tape pulling tool is positioned between the tape positioning tool and the tape positioning tool.

This tape cutter differs from the tape cutter according to claim 1 in that the cutter blade is fixed.
The action of forming a curled portion at the same time as cutting the tape is the same as described above. That is, when the tape is pulled out and cut by the cutter blade, the tape pulling tool returns to the tape positioning tool side by the biasing member, and the tape portion from the tip of the tape pulling tool to the tape positioning tool becomes a curled portion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments. FIG. 1 shows a perspective view of a main part of a tape cutter according to an embodiment. However, the cutter base for rotatably supporting the winding tape may be the conventional one shown in FIG.
It is convenient to use the cutter table described below. Here, only the main part will be described. The cutter unit 10 shown in FIG. 1 is an element other than a winding tape, and is provided at a portion where a cutter blade (not shown) is attached to a cutter blade. In this cutter unit 10, a tape positioning tool 11 having a U-shaped cross section for positioning the tape from the winding tape
A rotation shaft (guide member) 13 rotatably supported by the cutter base and supporting the cutter blade 12 so as to be capable of advancing and retracting with respect to the tape positioning tool 11 is arranged on the lower side surface of the. The tape positioning tool 11 may be arranged adjacent to the rotation shaft 13 in a state of being separated from the rotation shaft 13, or both sides of the tape positioning tool 11 (portions protruding from the cutter blade 12) may be extended and The extended portion may be wound around the rotary shaft 13. However, in terms of cost, it is advantageous to dispose the tape positioning tool 11 separately.

On the rotary shaft 13, one end portion 1 of the cutter blade 12 is provided.
2b is wound and the cutter blade 12 is rotated along with the rotation of the rotary shaft 13.
Swings around the rotary shaft 13 as a fulcrum. The blade tip (the other end) 12a of the cutter blade 12 is set so as to project from the tape positioning tool 11 by about 1 to 2 mm when the cutter blade 12 is adjacent to the tape positioning tool 11. A cutter blade 12 is provided at both ends of the rotary shaft 13 to provide a tape positioning tool 1
A pair of springs (biasing members) 14 that biases the first side is wound. The L-shaped one end 14a of the spring 14 is the cutter blade 1
2, and the other end 14b is locked to the cutter base. Therefore, the cutter blade 12 is constantly pressed by the spring 14 toward the tape positioning tool 11 side. Further, the cutter blade 12 has a leaf spring 15 whose tip is positioned at the same level as the blade tip 12a of the cutter blade 12 on the side facing the tape positioning tool 11 (see FIG. 2B).

The operation of the cutter unit 10 thus constructed will be described with reference to FIG. However, in FIG.
Is schematically shown, and the spring 14 is omitted. First, in FIG. 2 (a), when the tape 40 from the winding tape is pulled out in the direction of the arrow, the tape 40 becomes
Since the tape is pulled while being attached to a, the cutter blade 12 is displaced diagonally with the rotating shaft 13 as a fulcrum against the urging force of the spring 14 as the tape 40 is pulled out.

Subsequently, in FIG. 2B, when the tape 40 is pulled out to a certain extent, the tape 40 is cut by the force of the cutter blade 12 due to the restoring force of the spring 14. Then, the cutter blade 12 returns to the original position by the urging force of the spring 14. At this time, the tape 40 is attached to the tape positioning tool 11, and the cut end of the tape 40 is the cutting edge 1 of the cutter blade 12.
Since it is attached to 2a, the tape portion 41 'from the tape positioning tool 11 to the cutting edge 12a becomes loose and curls. Here, since the cutter blade 12 is provided with the leaf spring 15, when the tape portion 41 ′ is loosened, the tape portion 41 ′ is always slackened so as to project outward, and is not slackened inward as shown by a dotted line.

Then, in FIG. 2 (c), when the cutter blade 12 is completely returned to its original position, a neat curl-shaped (folded into two) tape portion 41 is formed.
Therefore, when the tape 40 is cut next time, the curl-shaped portion 41 is held and the tape 40 is pulled out as described above. Since the cut tape always has a curled portion (non-adhesive portion) at one end, it is easy to peel off after adhering, and it is not necessary to raise the end of the tape with a nail or the like.

FIG. 3 shows a cutter unit 20 of another embodiment.
Is shown. In this cutter unit 20, a cutter blade 22 is arranged adjacent to a tape positioning tool 21 having a U-shaped cross section, and the cutter blade 22 is movably guided together with the tape positioning tool 21 to a portion near the lower part of the cutter blade 22. Two guide shafts (guide members) 23 are inserted (see FIG. 4). As can be seen from FIG. 4, the two guide shafts 23 extend obliquely downward with respect to the side surface of the tape positioning tool 21, one end of which is fixed to the cutter base and the other end of which is the cutter blade 22 and the tape. It penetrates the positioning tool 21. Coil springs 24 are inserted into the two guide shafts 23, respectively. The cutter blade 22 is constantly pressed toward the tape positioning tool 21 by the coil spring 24, is guided by the guide shaft 23 and moves diagonally downward against the biasing force of the coil spring 24, or is moved to the original position by the biasing force of the coil spring 24. You can return to.

The operation of the cutter unit 20 shown in FIG. 3 will be described with reference to FIG. In FIG. 4A, as the tape 40 of the winding tape is pulled out in the arrow direction, the cutter blade 2
2 is guided by the guide shaft 23 and moves diagonally downward against the biasing force of the coil spring 24. When the tape 40 is pulled out to a certain extent, the cutter blade 22 stops moving due to the restoring force of the coil spring 24, and the tape 40 is cut [see (b) of FIG. 4]. Then, the cutter blade 22 returns to its original position by the coil spring 24, but at that time, the tape 40
Is attached to the tape positioning tool 21 and the cutting edge 22a of the cutter blade 22, so that the tape positioning tool 21 moves to the cutting edge 22a.
The tape portion 41 'up to a is loosened by the return of the cutter blade 22, and when the cutter blade 22 returns to the original position,
It becomes a curled portion (non-adhesive portion) 41 [(c) of FIG. 4]
reference〕.

Next, when the tape 40 is to be cut, if the curled portion 41 is held and pulled as described above, the tape having the curled portion 41 is cut, and at the same time, a new curled portion is formed at one end of the tape. Is formed. In addition,
In FIG. 4, the cutter blade 22 is not provided with the leaf spring 15 described above, but a leaf spring may be provided in the same manner to surely form the curled portion.

FIG. 5 schematically shows a cutter unit according to another embodiment. This cutter unit uses a roller 16 instead of the tape positioning tool 11 having a U-shaped cross section in the cutter unit shown in FIG. The roller 16 is rotatably supported on the cutter table. In this case, FIG.
Although the same effect as the above is obtained, the roller 16 is rotatable and the adhesive area with the tape 40 is smaller than that of the immovable tape positioning tool 11, so that the tape 40
It becomes easier to pull out.

Further, FIG. 6 schematically shows a cutter unit of another embodiment. In this cutter unit, a cutter blade 18 is fixed separately from the tape drawing tool 17. That is, the tape pull-out tool 17 is biased toward the tape positioning tool 11 side by a biasing member (for example, a spring), and the cutter blade 18 is fixed to the cutter stand so that the tape pull-out tool 17 is positioned between the tape positioning tool 11. Has been done.

In FIG. 6A, when the tape 40 is pulled out, the tape pulling tool 17 tilts toward the cutter blade 18 with the tape 40 attached to the tip. FIG. 6B
Then, when the tape 40 is cut by the cutter blade 18, the tape pull-out tool 17 returns to the tape positioning tool 11 side by the spring. Since the tape 40 is attached to the tip of the tape pull-out tool 17, the tape portion 41 ′ from the tape positioning tool 11 to the tip of the tape pull-out tool 17 becomes a curled portion 41 (see FIG. 6C).

The various cutter units as described above are shown in FIG.
Although it may be attached to a conventional cutter table as shown in Fig. 6, since such a cutter table is usually placed on a desk, it has a certain weight (about 1 kg depending on the size). In addition, not only is it a considerable weight when they are collectively transported, but it is also inconvenient to carry them individually. Therefore, it is convenient to use the cutter base 1 as shown in FIG. 7 in order to solve such a problem. FIG.
8 is a front view of the cutter stand with the winding tape attached, FIG.
8A is a top view of the cutter table, and FIG. 8B is a right side view of FIG. 8A.

The cutter base 1 in FIG. 7 is made of metal, for example, iron plated with nickel. The cutter base 1 includes a rectangular bottom plate 2, a pair of rear plates 3 erected face-to-face with a rear end of the bottom plate 2 with a space therebetween, and rotatably supporting a winding tape 44, and a front end of the bottom plate 2. And a pair of front plates 4 to which the elements (cutter unit) other than the winding tape 44 are mounted and which face each other in a parallel direction with the rear plate 3 at intervals. The rear plate 3 and the front plate 4 have the same height, and in fact, the rear plate 3 is slightly inclined inward (see FIG. 8B). The bottom plate 2, the rear plate 3, and the front plate 4 may be integrally molded, or separately manufactured may be joined by welding, screws, or the like.

A reinforcing plate 5 is installed between the pair of front plates 4. Further, the pair of rear plates 3 are each formed with a notch 6 into which the rotary shaft 46 of the rotary frame 45 fitted inside the winding tape 44 is fitted, and the pair of front plates 4 are provided with the cutters shown in FIG. The holes 7 through which the rotary shafts 13 of the units are inserted are respectively formed. Further, magnets 8 and 9 are attached to the rear end and the front end of the bottom plate 2, respectively. Magnet 8,
9 is for fixing the cutter base 1 to a desk or a wall,
Depending on the case, it may be possible to fix with a screw or the like instead of the magnet.

In the cutter base 1 thus constructed, the rotary frame 45 is fitted inside the winding tape 44, the rotary shaft 46 is fitted in the notch 6 of the rear plate 3, and the cutter unit is mounted on the front plate 4. To use. The action associated with the tape cutting is as described above. The cutter base 1 can be reduced in weight from its structure to about 150 g. For this reason, it is convenient to carry individual items or to carry them all together. Moreover,
Since the bottom plate 2 is provided with the magnets 8 and 9, it can be fixed not only on the desk but also on the side or the wall of the desk, and the degree of freedom of the mounting place is great.

Although the cutter base 1 is constructed so that the cutter unit shown in FIG. 1 is mounted, it may be appropriately changed in the case of other cutter units. For example, in the case of the cutter unit shown in FIG. 5, a hole for rotatably supporting the rotary shaft of the roller 16 may be formed in the front plate 4, and in the case of the cutter unit shown in FIG. You can fix it to.

[0026]

Since the tape cutters according to the first and sixth aspects of the present invention are constructed as described above, when the tape is cut, a curled portion is always formed at one end of the tape. . Therefore, when cutting the tape next time, if you pull out the tape by holding the curled portion, the cut tape has a curled portion (non-adhesive portion) at one end, so that electronic components and papers are bonded together. The tape can be easily peeled from the curled portion when it is necessary to peel it off after bonding, such as packing in a nylon bag or a vinyl bag.

Accordingly, the tape peeling work is facilitated, and there is no problem that the adherend is scratched by a nail or the like to be scratched, or is forcibly peeled off to damage the adherend. Further, according to the tape cutter of the seventh aspect, the weight of the cutter table can be reduced, and it becomes very easy to carry the cutter as a unit or carry a single item. Furthermore, by attaching a magnet to the bottom plate of the cutter stand (claim 8), the tape cutter can be used not only on the desk,
It can be fixed to the side of a desk or a wall, increasing the degree of freedom of mounting location.
