Description

Label roll

The present invention relates to a label roll, and, for example, relates to a label roll formed by winding a plurality of no-separator labels into a belt shape.

¡No-separator labels that do not use release paper (separator) are widely used as labels to be attached to adherends such as products because they contribute to reducing environmental impact with little waste. There are various types of no-separator labels. For example, Patent Document 1 discloses a label roll W (see FIG. 4) in which a strip-shaped label group (label body) 8 formed in a strip shape by connecting a plurality of no-separator labels 1 is wound around a tubular core 7 in a roll shape. Proposed.

Specifically, as shown in FIG. 4 (a), the label roll W is a strip-shaped label group 8 formed by shifting and connecting no-separator labels (hereinafter simply referred to as “labels”) 1 one by one. Is rolled into a roll. The label 1 is formed on a label base 2 having a product name or the like printed on the surface (upper surface), an overcoat layer (peeling layer) 3 formed on the surface of the label base 2, and a back surface of the label base 2. And an adhesive layer (adhesive layer) 4 (see FIG. 4B).

Also, it has been proposed to attach the label roll W to a labeling machine (label application device) and automatically apply a label to an adherend. For example, Patent Document 2 proposes a label sticking device that attaches the label roll W as described above, peels off the label 1 from the label roll W, and automatically sticks it to an adherend. This label sticking apparatus is a belt conveyor that moves an adherend, a label support part that rotatably supports a label roll W, and a label 1 that is drawn from the label roll W supported by the label support part in a belt state. A label attaching mechanism for peeling the labels 1 one by one from the belt state and attaching the labels to the adherend is provided.

Japanese Patent No. 3205804 WO 2010/101101 A1

However, as shown in FIG. 5, the above-described prior-art label roll W pulls its tip and pulls the label 1 in the form of a band (band-shaped label group 8), while the band-shaped label group 8. Has the technical problem of being interrupted. That is, the label roll W may not be able to pull out the label 1 continuously. Therefore, when the label roll W is mounted on the label sticking apparatus as described above, the label 1 is frequently interrupted, and the automatic sticking process is frequently interrupted.

Then, when this inventor investigated the cause of the said subject, the joining force of the label which comprises a label roll, and the succeeding label adhere | attached adjacent to the label adheres to the back surface of the said label 1 It has been found that the fact that the bonding force with the band-shaped label group arranged in the lower layer is smaller than the label roll cannot be pulled out continuously from the label roll. Hereinafter, the cause will be described in detail with reference to FIGS. 6 and 7.

Here, FIG. 6 and FIG. 7 are schematic diagrams for explaining the adhesive relationship between the labels of the label roll constituted by the conventional no-separator label, and FIG. 6 is a state in which the labels are shifted between the upper and lower layers. 7 shows a state where the labels overlap each other at the same position in the upper and lower layers. In addition, the code | symbol 8A in a figure has shown the strip | belt-shaped label group of the upper layer side, and the code | symbol 8B has shown the strip | belt-shaped label group of the lower layer side. Reference numerals 1A _n, 1A _{n + 1,} 1A _{n + 2} (n is an integer equal to or greater than 1) indicate labels constituting the upper-layer strip label group 8A, and reference numerals 1B _n, 1B _{n + 1,} 1B _{n + 2} (n is an integer equal to or greater than 1) ) Shows labels constituting the lower band side band-like label group 8B. Further, in the figure, the area indicated by horizontal line hatching indicates “adhesion area S1 (adhesion area S1 of label 1A _n and label 1A _{n + 1} )” between adjacent labels, and the area indicated by hatching is between the upper and lower layers. The label shows the “adhesion area S2 (adhesion area S2 between the label 1A _{n + 1} and the lower belt-like label group 8B)”.

Then, as shown in FIGS. 6 and 7, the label roll W of the prior art, regardless of the position of the label between the upper and lower layers, both a label 1A _n constituting the "upper layer of the strip the labels 8A, subsequent label "Adhesion area S1 with 1A _{n + 1} " is from "Adhesion area S2 between subsequent label 1A _{n + 1} and strip-shaped label group 8B (label 1B _n and subsequent label 1B _{n + 1} ) one level lower than subsequent label 1A _{n + 1} " It is getting smaller. In this label roll W, the “bonding force F1 between the label 1A _n constituting the upper strip-shaped label group 8A and the subsequent label 1A _{n + 1} ” is determined by the “bonding area S1”. Further, “the bonding force F2 between the succeeding label 1A _{n + 1} and the strip-shaped label group 8B one level lower than the succeeding label 1A _{n + 1} ” is determined by the “adhesion area S2”.

That is, the label roll W of the prior art has “adhesion area S1 <adhesion area S2”, and as a result, “the bonding force between the label 1A _n constituting the upper strip-shaped label group 8A and the subsequent label 1A _{n + 1”.} “F1” was smaller than “joining force F2 between the succeeding label 1A _{n + 1} and the belt-like label group 8B (label 1B _n and succeeding label 1B _{n + 1} ) one level lower than the succeeding label 1A _{n + 1} ”. Therefore, in the prior art, when pulled label 1A _n, succeeding label _{1A n + 1} coupled to a label 1A _n is remained without peeling from the underlying strip the labels 8B (labeled 1B _n, succeeding label _{1B n + 1)} behavior that apart from the label 1A _n has occurred (a phenomenon that can not be drawn label 1 continuously from the label roll W had occurred).

Furthermore, the inventor of the present application has examined the relationship between the “bonding area S1” and the “bonding area S2”. As a result, in the label roll W, adjacent labels 1 are connected so that the “adhesion area S1” is constant (predetermined value), but the “adhesion area S2” is determined by the strip-shaped label group 8 in the label roll W. It was found that the position was different depending on the position. Specifically, as the strip-shaped label group 8 constituting the label roll W is directed from the inner peripheral side to the outer peripheral side of the label roll W, the circumferential length thereof increases. Therefore, the overlapping state of the strip-shaped label group 8 and the strip-shaped label group 8 disposed in a layer lower than itself varies depending on the position where the strip-shaped label group 8 is disposed (the adhesive area S2 varies accordingly). That is, the band-like label group 8 has a different bonding force F2 with the band-like label group 8 below itself depending on the position of the band-like label group 8.

For example, in FIG. 6, the ends of the labels 1A _n, 1A _{n + 1,} 1A _{n + 2} arranged on the upper layer side, and the ends of the labels 1B _n, 1B _{n + 1,} 1B _{n + 2} arranged one layer lower than the label 1A _n, 1A _{n + 1,} 1A _{n + 2} It overlaps in a state shifted by “predetermined length dimension X1 (X1> 0)”. In this case, the “adhesion area S2” is smaller than the area obtained by subtracting the “adhesion area S1” from the total area SA of the back surface of the label 1A _{n + 1} (S2 <(SA−S1). When the labels 1 are overlapped with each other in the state where the labels 1A _and 1B are deviated from each other, even if the label 1A _{n + 1} on the upper layer side is an area other than the adhesive portion with the subsequent label 1A _{n + 2} , the labels 1B _n, 1B _{n + 1,} 1B _{n + 2} In this case, even if the “length dimension X1 (X1> 0)” changes, the “adhesion area S2” is always determined from the total area SA on the back surface of the label 1A _{n + 1.} It is smaller than the area minus S1.

On the other hand, as shown in FIG. 7, the labels 1A _n, 1A _{n + 1,} 1A _{n + 2} arranged on the upper layer side overlap with the labels 1B _n, 1B _{n + 1,} 1B _{n + 2} arranged one layer lower than that. (The case where the upper and lower layer labels 1 are completely coincident and overlap), the “adhesion area S2” of the label 1A is an area obtained by subtracting the adhesion area S1 from the total area SA of the back surface of the label 1A. (S2 = SA-S1).

That is, the bonding force F2 of the label 1 between the upper and lower layers becomes maximum when the upper layer side label 8A and the lower layer side label 8B are completely coincident and overlapped (in the case shown in FIG. 7). Therefore, if the “adhesive area S1 between adjacently connected labels 1” that can be designed as a fixed value is set so as to be larger than the maximum joining force F2, the label 1 is continued from the label roll W. Can be pulled out. Specifically, in each of the labels 1 constituting the label roll W, a strip-shaped label in which the adhesive area S1 between adjacent labels 1 is arranged in a lower layer bonded to the back surface of the label. If adjacent labels are connected so as to be larger than the adhesion area S2 with the group 8, a label roll W that can continuously pull out the label 1 is realized.

However, at present, there is no known label roll configured in consideration of the relationship between the adhesive area between adjacently connected labels and the adhesive area between labels between upper and lower layers.

The present invention has been made in view of the above technical problem, and an object of the present invention is to enable continuous drawing of labels in a label roll formed by connecting a plurality of no-separator type labels. It is in.

The present invention for solving the above technical problem is to roll a strip-like label group formed by repeatedly connecting a stack of no-separator-type labels that do not use a release paper, shifted one by one. The label has an overcoat layer formed on the surface thereof, an adhesive layer formed on the back surface thereof, and each label constituting the strip-shaped label group has the adhesive layer formed thereon. The surface of the subsequent label connected adjacent to the label is overlapped and bonded to the back surface, and each label has an adhesive area with the subsequent label bonded to the back surface bonded to the back surface. It is characterized by being larger than the adhesion area with the strip-shaped label group arranged in the lower layer.

As described above, in the present invention, each label constituting the label roll has an adhesive area with a subsequent label bonded to the back surface, and an adhesive with a band-shaped label group arranged in a lower layer bonded to the back surface. It is larger than the area. Therefore, in this invention, the joining force of each label which comprises a label roll, and the subsequent label adjacent to the label becomes larger than the joining force with the strip | belt-shaped label group of one step lower layer rather than the label. Therefore, according to the present invention, it is possible to prevent the label from being interrupted in the middle while the tip of the label roll is pulled and the label is pulled in a band shape. That is, according to the present invention, there is provided a “label roll composed of no-separator labels” capable of continuously drawing out labels. Therefore, when the label roll of the present invention is used by being attached to a label sticking device, the label will not be interrupted while the label is being drawn out in a belt-like form. It can be done efficiently.

In addition, it is desirable that adjacent labels are connected so that the adhesion area with the subsequent label adhered to the back surface is 50% to 95% of the total area of the back surface.

This configuration makes it possible to pull out the label continuously from the label roll more reliably. In addition, when a label roll is attached to the label sticking apparatus and the label is automatically stuck on the adherend, the label sticking apparatus performs an operation of peeling the labels one by one from the label roll. For this reason, the label and the succeeding label connected to the label need to be overlapped with a predetermined region (predetermined area) shifted. The “predetermined area” is the size and shape of the label itself. Is set as appropriate. Then, if the adhesive area with the subsequent label adhered to the back surface is configured to be 50% to 95% of the total area of the back surface, the label sticking device can peel the labels one by one from the label roll. A “predetermined area” is secured. That is, with this configuration, both the continuous pulling of the label from the label roll and the peeling of the label from the label roll one by one are realized.

Each label has a stepped portion formed by a label superimposed on the back surface thereof, and the back surface of the label is divided into a plurality of horizontal regions by the stepped portion. It is desirable that it is less than 50% of the total area of the back surface.

The reason for this configuration is as follows. Specifically, the belt-like label group constituting the label roll is wound in a roll shape with a predetermined tension. Therefore, the belt-like label group receives a pressing force from the belt-like label group arranged in an upper layer than itself and receives a reaction force (a reaction force against the pressing force) from the belt-like label group arranged in its lower layer. ing. That is, each label constituting the label roll is sandwiched with a predetermined pressure from the labels arranged in the upper and lower layers of the label roll. As a result, in each label constituting the label roll, the adhesive paste forming the adhesive layer on the back surface thereof changes over time due to the influence of the predetermined pressure, and a phenomenon occurs that the label protrudes from the back surface of the label to the outer peripheral edge. Adhesive glue that protrudes from the back of the label may cause the adjacent labels to adhere to each other, which makes it difficult to remove the labels one by one from the label roll.

In the present invention, “a plurality of horizontal regions formed on the back surface of the label are less than 50% of the total area of the back surface, and thus protrude from the back surface of the label to the outer peripheral edge of the label. Therefore, according to the present invention, adhering between adjacent labels due to the adhesive paste protruding from the back side of the label is prevented, and as a result, the phenomenon that the label is difficult to peel off from the label roll is prevented. The

According to the present invention, it is possible to continuously draw out a label in a label roll formed by connecting a plurality of no-separator labels.

Hereinafter, a label roll according to an embodiment of the present invention will be described with reference to the drawings. First, the label roll of 1st Embodiment of this invention is demonstrated using FIG. In the following description, the same reference numerals are assigned to the same configurations as those of the above-described conventional technology and the corresponding configurations. Moreover, the code | symbol 8A in a figure has shown the strip | belt-shaped label group of the upper layer side, and the code | symbol 8B has shown the strip | belt-shaped label group of the lower layer side.

As shown in FIG. 1, the label roll L of the first embodiment is a strip-shaped label group formed by laminating and connecting no-separator labels (hereinafter referred to as “labels”) 1 that do not use release paper one by one. It is formed by winding 8 around the core 7 in a roll shape.

Further, the label 1 constituting the label roll L includes a label base portion 2 on which a printing surface on which a product name or the like is printed is formed on the surface, as in the conventional technology described above. Further, an overcoat layer 3 coated with an overcoat agent is formed on the surface (printing surface) of the label base 2. The overcoat layer 3 protects the printing surface and facilitates peeling of the superimposed label 1. The label 1 has an adhesive layer 4 formed on the entire back surface (lower surface) of the base 2. Moreover, in 1st Embodiment, although the example in which the label 1 is formed in the circular shape is shown as an example, the shape of the label 1 is only an example.

The label base 2 is, for example, a polyester film (PET (polyethylene terephthalate)) having a thickness dimension of “30 to 80 μm”, a polypropylene film having a thickness dimension of “50 to 90 μm”, and a thickness dimension of “40 to 80 μm ”synthetic paper or the like. For the overcoat agent, for example, UV varnish or aqueous varnish can be used. The adhesive layer 4 is formed by applying, for example, rubber hot melt, UV curable acrylic hot melt, or the like. The thickness dimension of the overcoat layer 3 is, for example, “1 to 2 μm”, and the thickness dimension of the adhesive layer 4 is, for example, “15 to 20 μm”.

The illustrated strip-shaped label group 8 is formed on the surface of the second label 1b (subsequent label of the first label 1a) on the rear end side of the adhesive layer 4 formed on the back surface of the first label 1a. The surface of the third label 1c (subsequent label of the second label 1b) is attached to the rear end side of the adhesive layer 4 formed on the back surface of the second label 1b. The overcoat layer 3 is formed by sequentially attaching the tip side of the overcoat layer 3.

And in 1st Embodiment, as shown in FIG.1 (b), each label 1 which comprises the strip | belt-shaped label group 8A of the upper layer side is connected with the subsequent label 1 adhere | attached and connected to the back surface. Adhering labels 1 adjacent to each other are bonded so that the bonding area S1 of the sheet is larger than the bonding area S2 with the strip-shaped label group 8B arranged in one lower layer than itself bonded to the back surface thereof. . In addition, when each label 1 which comprises the strip | belt-shaped label group 8A satisfy | fills "adhesion area S1> adhesion area S2," the adhesion area S1 with the subsequent label 1 adhere | attached on the back surface of the label 1 at least is this The requirement is that it is larger than 50% of the adhesive surface (total area of the back surface of the label 1) formed on the back surface.

Specifically, in the first embodiment, even in a case where the “bonding force F2” between the label 1 and the strip-shaped label group 8 on the lower layer of the label 1 is maximum (the case of FIG. 7), The bonding area S1 between the adjacent labels 1 is defined so that the “bonding force F1 between the labels 1 to be performed” is larger than the “bonding force F2”. That is, even when the labels 1 are completely overlapped at the same position between the upper and lower layers (adhesion area S1 + adhesion area S2 = SA (total area on the back side of the label 1)), “adhesion area S1> adhesion area S2”. The bonding area S1 is calculated so as to satisfy the above expression, so that “bonding area S1> SA × 0.5”.

A label roll is formed by connecting the adjacent labels 1 to each other such that the adhesion area S1 with the subsequent label 1 adhered to the back surface of the label 1 is larger than 50% of the total area SA of the back surface. In each of the labels 1 constituting L, the adhesion area S1 with the subsequent label 1 is larger than the adhesion area S2 with the strip-shaped label group 8 arranged in the lower layer bonded to the back surface. That is, in the label roll L, “joining force F1 between adjacent labels 1” is larger than “joining force F2”. Therefore, according to the first embodiment, it is possible to prevent the label 1 from being interrupted in the middle while the front end of the label roll L is pulled and the label 1 is pulled in a strip shape.

Further, according to the first embodiment, the amount of adhesive paste (adhesive adhesive forming the adhesive layer 4) that protrudes from the back surface of the label 1 to the outer peripheral edge portion of the label 1 as compared with the prior art shown in FIG. Can be reduced. That is, according to the first embodiment, the amount of the adhesive paste that protrudes from the outer peripheral edge of the label 1 is reduced, so that adjacent labels due to the adhesive paste are prevented from sticking together. As a result, according to the first embodiment, a phenomenon that the label 1 is difficult to be peeled off from the label roll L as compared with the above-described conventional technology is prevented.

Hereinafter, with reference to FIG. 2, the influence of the adhesive paste protruding from the outer peripheral edge of the label 1 will be described. FIG. 2 is a schematic diagram for explaining the state of the adhesive paste protruding from the back side of the label according to the first embodiment of the present invention, (a) is a schematic diagram showing a cross section of the label, and (b). Is a schematic diagram showing a state where the adhesive paste protrudes from the back side of the label of the label roll of the prior art, and (c) is a schematic diagram showing a cross section of a strip-shaped label group constituted by the labels of the first embodiment. It is.

The strip-shaped label group 8 constituting the label roll L is wound in a roll shape with a predetermined tension. Therefore, the belt-like label group 8 receives a pressing force from the belt-like label group 8 arranged in an upper layer than itself, and a reaction force from the belt-like label group 8 arranged in its lower layer (reaction force against the pressure force). )Is receiving. That is, each label 1 constituting the label roll L is sandwiched with a predetermined pressure from the labels 1 arranged in the upper and lower layers of the label roll L. As a result, in each label 1 constituting the label roll L, the adhesive glue forming the adhesive layer 4 on the back surface thereof changes with time due to the influence of the predetermined pressure, and the phenomenon that the label 1 protrudes from the back surface to the outer peripheral edge portion. It occurs (changes from FIG. 2A to FIG. 2B).

In the example of the first embodiment (example shown in FIG. 2C), two labels 1a2 and 1a3 are superimposed on the back surface of the label 1a1, and each label 1 has two steps. Is formed. Further, the back surface of each label 1 is divided into a plurality of horizontal regions (three horizontal regions E1, E2, E3) by a step portion. When the adjacent labels 1 are bonded so that the bonding area S1 is larger than “50% of the total area SA of the back surface of the label 1”, the horizontal regions E1, E2, and E3 formed on the back surface of the label 1a1 are , Both are smaller than 50% of the total area SA on the back surface of the label 1.

On the other hand, in the above-described prior art (FIG. 4), each label 1 is partitioned into “two horizontal regions E1, E3” partitioned by a stepped portion, but among the “two horizontal regions E1, E3” The horizontal area E1 (the horizontal area E1 on the front end side of the label 1) that is the maximum area is 50% or more of the total area SA on the back surface of the label 1.

The adhesive glue that is to be projected from the back surface of each label 1 to the outer peripheral edge is an adhesive paste that is applied (or applied) to the horizontal regions E1 and E3 that form the same horizontal plane as the outer peripheral edge of the label 1a. In the first embodiment, since the area of the horizontal region E1 can be reduced as compared with the above-described prior art, the amount of adhesive paste that protrudes from the back surface of the label 1 to the outer peripheral edge of the label 1 is reduced (see reference numeral B1). . Therefore, according to 1st Embodiment, the adhesion of the adjacent labels 1 by the adhesive paste which protruded from the label 1 back surface is prevented. As a result, according to the first embodiment, the phenomenon that the label 1 is difficult to peel from the label roll L is prevented.

It should be noted that as the adhesive area S1 becomes larger than “50% of the total area SA of the back surface of the label 1”, the number of labels 1 stacked on the back surface of each label 1 increases. Therefore, the number of step portions formed in each label 1 increases, and as a result, the number of horizontal regions E divided by the step portions also increases. That is, as the adhesion area S1 becomes larger than “50% of the total area SA on the back surface of the label 1”, the area of each horizontal region E also becomes smaller.

Therefore, by making the adhesive area S1 larger than “50% of the total area SA of the back surface of the label 1”, not only the adhesive paste protruding from the outer peripheral edge of the front end side of the label 1 but also the rear end side of the label 1 The amount of adhesive paste that protrudes from the outer peripheral edge is also reduced. As a result, in the first embodiment, in addition to preventing the adhering labels 1 from adhering to each other by the adhesive paste (see reference numeral B1), further, the adhering of the labels 1 between the upper and lower layers by the adhesive adhesive is prevented. (See symbol B2). Therefore, in the first embodiment, the phenomenon that the label 1 is difficult to peel off from the label roll L is prevented. Further, according to the first embodiment, the label 1 generated due to the adhesive paste protruding from the back surface of the label 1 is prevented from being interrupted in the middle.

As described above, according to the first embodiment, it is possible to provide the label roll L that can continuously draw out the no-separator label.

Next, the label roll according to the second embodiment of the present embodiment will be described with reference to FIG. FIG. 3 is a schematic diagram of a label roll according to the second embodiment of the present invention, in which (a) is a schematic diagram showing a plane of a strip-shaped label group constituting the label roll, and (b) is (a FIG. 6 is a schematic diagram showing a cross section taken along the line AA of the strip-shaped label group shown in FIG. In the second embodiment, the same reference numerals are given to the same configurations as those in the first embodiment and the corresponding configurations.

In the second embodiment shown in the figure, each label 10 constituting the label roll L is formed in a rounded rectangle. Further, the label 10 is a no-separator label, as in the first embodiment, and includes a label base 2, an overcoat layer 3 formed on the surface of the label base 2, and an adhesive layer formed on the back of the label base 2. 4. In the second embodiment as well, as in the first embodiment, the label roll L is configured by winding a strip-shaped label group 8 formed by shifting and overlapping the labels 10 one by one in a roll shape. ing.

And in 2nd Embodiment, each label 10 which comprises the strip | belt-shaped label group 8 to show in figure is the adhesive area S1 with the adjacent succeeding label 10 adhere | attached and connected to the back surface, The total area SA of the said back surface Adjacent labels 10 are connected so as to be 75% to 95%. In addition, this adhesion area S1 is appropriately set according to the thickness dimension of the adhesive layer 4 (coating thickness of the adhesive paste) of the label 10. For example, when the thickness dimension of the adhesive layer 4 of the label 10 is “15 μm”, the adhesive area S1 is desirably 75% or more and less than 95% of the total area SA of the back surface. For example, when the thickness dimension of the adhesive layer 4 of the label 10 is “20 μm”, the adhesive area S1 is desirably 80% or more and less than 95% of the total area SA of the back surface.

The reason for this configuration is to enable the label 10 to be continuously pulled out from the label roll L more reliably. In addition, when attaching the label roll L to a label sticking apparatus and sticking the label 10 to a to-be-adhered body, in order to peel off the label 10 one by one from the label roll L, the one label 10 and the label 10 are adhere | attached. The adjacent succeeding labels 10 connected to each other need to be overlapped in a state shifted by “predetermined area S3”. The “predetermined area S3” is set according to the size and shape of the label 10 itself. For example, when the shape of the label 10 is rectangular and the size (area) is “28 mm × 28 mm size”, the “predetermined area S3” is “11 to 25%” of the total area SA on the back side of the label 10. If it is a grade, the peeling error of the label 10 in the process in which the label sticking apparatus peels the label 10 from the label roll L one by one is prevented. Further, for example, when the shape of the label 10 is rectangular and the size (area) is “size of 50 mm × 50 mm”, the “predetermined area S3” is “8 to 14” of the total area SA of the back surface of the label 10. % ”, The peeling error of the label 10 is prevented. Further, for example, when the shape of the label 10 is rectangular and the size (area) is “75 mm × 75 mm”, the “predetermined area S3” is “7 to 11” of the total area SA on the back surface of the label 10. % ”, The peeling error of the label 10 is prevented. Further, when the shape of the label 10 is rectangular and the size (area) thereof is “100 mm × 100 mm”, the “predetermined area S3” is “4 to 10%” of the total area SA on the back surface of the label 10. If it is, the peeling error of the label 10 is prevented.

Thus, also in the second embodiment of the present invention, as in the first embodiment described above, the label roll L that can continuously pull out the label 10 is realized. Moreover, according to 2nd Embodiment, both pulling out the label 10 from the label roll L continuously and peeling the label 10 from the label roll L one by one are implement | achieved.

The present invention is not limited to the above-described embodiments (first and second embodiments), and various modifications can be made within the scope of the gist.
