Description

Technical Field

[0001] The present disclosure relates to a clamp, and more particularly, to a label laminating apparatus. Background Art

[0002] As described in Japanese Patent Application Laid-Open No. 2009-066835, a label laminating device is known that is configured to adhere a second label in the form of a strip to a first label in the form of a strip in a stacked manner. Each of the first label and the second label includes a base tape, an adhesive layer formed on the lower surface of the base tape, and a release tape bonded to the lower surface via the adhesive layer.

[0003] The label stacking device includes a guide portion and a fixing portion. The guide portion is configured to guide the respective end surfaces of a first label and a second label along a guide surface to fix the relative positions thereof. The fixing portion is configured to fix the first label and the second label stacked above the first label against the guide portion.

[0004] In the conventional label stacking device, the first label and the second label can be positioned perpendicular to the guide surface. However, the first label and the second label need to be positioned parallel to the guide surface manually by the user.

[0005] Furthermore, to adhere the two labels to each other, with the second label superimposed on the first label, the user partially peels the peeling tape off the second label while the first and second labels are fixed in place relative to each other, and rolls up the peeled portion of the peeling tape; and then adheres the exposed adhesive layer of the second tape to the first tape. Here, since the size of the base tape of the second label is equal to the size of the peeling tape of the second label, the labor of adhering the first and second tapes to each other requires the user's skill, and therefore, poor adhesion is likely to occur. Summary of the Invention

[0065] <First embodiment>

[0066] Will refer to Figures 1 to 11B A clamp 1 according to a first embodiment of the present disclosure is described.

[0067] In the following description, directions such as front, back, top, bottom, left, and right will be referred to based on those directions indicated in the drawings. The orientation or posture of the clamp 1 will be described based on the directions indicated in the drawings. Figures 8 to 11B The directions indicated in refer to the orientation of the lower and upper tags 11 and 12 to be used in the clamp 1 .

[0068] Will refer to Figures 1 to 6 The structure of the jig 1 will be described.

[0069] like Figures 1 to 3 As shown in FIG, the clamp 1 includes a base plate 2 and a pressure plate 3. The base plate 2 and the pressure plate 3 are both made of resin. The pressure plate 3 is in the closed position ( Figures 1 to 3 ) and open position ( Figures 4 to 6 ) are pivotally connected to the base plate 2.

[0070] like Figure 4 and Figure 5As shown in , in a plan view, the base plate 2 is a generally rectangular plate member elongated in the left-right direction. The base plate 2 has four tapered corners, each of which has a generally arcuate shape in a plan view. The base plate 2 has an upper surface 21, on which hinges 22 and 23, an engaging protrusion 24, five first ribs 25 (251, 252, 253, 254, 255), a second rib 26, and four magnets 271, 272, 273, and 274 are provided. Three rectangular recesses 291, 292, and 293 are also formed on the upper surface 21.

[0071] Hinges 22 and 23 are located at the rear end of the upper surface 21 of the base plate 2, such that the hinges 22 and 23 are spaced apart from each other in the left-right direction. Each of the hinges 22 and 23 has a generally rectangular parallelepiped shape that protrudes upward from the upper surface 21 and extends in the left-right direction. Each of the hinges 22 and 23 is formed with an axial hole (not shown) that is located at the center of the hinge in a side view and extends throughout the entire length of the hinge in the left-right direction.

[0072] The engaging protrusion 24 is located between the hinges 22 and 23 in the left-right direction. The engaging protrusion 24 has a generally rectangular parallelepiped shape that protrudes upward from the upper surface 21. Five first ribs 251 to 255 are arranged in a straight line on the upper surface 21 at intervals in the left-right direction. Specifically, in a plan view, the five first ribs 251 to 255 are arranged in a straight line on an imaginary straight line that extends in the left-right direction and is located in front of the approximate center of the upper surface 21 in the front-to-back direction in the plan view. Each first rib 25 (251 to 255) protrudes upward from the upper surface 21 and extends in the left-right direction. The length of the rightmost first rib 251 in the left-right direction is shorter than the length of each of the remaining first ribs 252 to 255 in the left-right direction.

[0073] The second rib 26 protrudes upward from the upper surface 21. The second rib 26 extends in a straight line toward the front end of the upper surface 21 from a position adjacent to the right end of the rightmost first rib 251. That is, the second rib 26 extends in a direction perpendicular to the extension direction of each first rib 25 (251 to 255) (i.e., in the front-to-back direction). The second rib 26 has a generally rectangular shape in a plan view. The height of the second rib 26 from the upper surface 21 is equal to the height of each first rib 25 (251 to 255). Incidentally, the protruding length of the second rib 26 from the upper surface 21 and the protruding length of the first ribs 251 to 255 are greater than the sum of the thickness of the lower label 11 and the thickness of the upper label 12.

[0074] The upper surface 21 has a label placement area 211 divided by the first ribs 251 to 255 and the second rib 26. Specifically, the front surfaces of the first ribs 251 to 255 define the rear edge of the label placement area 211, and the left surface of the second rib 26 defines the right edge of the label placement area 211. As will be described later, the lower label 11 and one side portion (rear end portion) of the upper label 12 superimposed thereon are as shown in FIG. Figure 8 is placed on the label placement area 211 as shown in FIG.

[0075] Each of the four magnets 271 to 274 has a disk shape and is embedded in a circular recess (not shown) formed in the upper surface 21 of the base plate 2. The upper surface of the respective magnets 271 to 274 is flush with the upper surface 21.

[0076] Three rectangular recesses 291 to 293 are located in the label placement area 211. The rectangular recesses 291 to 293 are arranged in the left-right direction at intervals. Each of the rectangular recesses 291 to 293 has a rectangular shape elongated in the left-right direction in a plan view and is recessed downward from the upper surface 21.

[0077] Next, the structure of the pressure plate 3 will be described.

[0078] like Figures 1 to 3 As shown in , the pressure plate 3 is a plate-like member having a generally rectangular shape elongated in the left-right direction in a plan view. The length of the pressure plate 3 in the left-right direction is approximately equal to the length of the base plate 2 in the left-right direction. The length of the pressure plate 3 in the front-to-back direction is shorter than the length of the base plate 2 in the front-to-back direction. For example, the front-to-back length of the pressure plate 3 is approximately two-thirds of the front-to-back length of the base plate 2. The pressure plate 3 has a rear end portion positioned to be aligned with the rear end portion of the upper surface 21 of the base plate. The rear end portion of the pressure plate 3 is pivotally movably connected to the base plate 2 by hinges 22 and 23, so that the pressure plate 3 can be in the open position ( Figures 4 to 6 ) and closed position ( Figures 1 to 3 ) to move between.

[0079] The pressure plate 3 has a front end portion provided with an operating portion 31. The operating portion 31 has a rib-like shape extending along the front end portion of the pressure plate 3 and protruding upward therefrom. The rear end portion of the pressure plate 3 is formed with three rectangular grooves 32, 33 and 34. When the pressure plate 3 is placed in the open position (see FIG. Figure 4 and Figure 5 ), each of the rectangular grooves 32 to 34 has a generally U-shape that opens downward when viewed from the front side of the clamp 1.

[0080] The rectangular groove 32 is the rightmost groove among the grooves 32 to 34 and is located at a position corresponding to the position of the hinge 22 of the base plate 2 in the left-right direction. The length of the rectangular groove 32 in the left-right direction is long enough to receive the hinge 22 therein. The rectangular groove 33 is the leftmost groove among the grooves 32 to 34 and is located at a position corresponding to the position of the hinge 23 of the base plate 2 in the left-right direction. The length of the rectangular groove 33 in the left-right direction is long enough to receive the hinge 23 therein.

[0081] The rectangular groove 34 is located midway between the rectangular groove 32 and the rectangular groove 33 in the left-right direction. A mating engagement plate 341 is provided in the rectangular groove 34. The mating engagement plate 341 is located at the upper inner portion of the rectangular groove 34 and is used to close the rectangular groove 34 when the pressure plate 3 is in the closed position. The mating engagement plate 341 is configured to engage with the engagement protrusion 24 when the pressure plate 3 is in the open position. The rectangular groove 34 is long enough in the left-right direction to receive the engagement protrusion 24 therein.

[0082] A shaft hole (not shown) is formed in the rear end portion of the pressure plate 3. The shaft hole extends in the left-right direction to penetrate the rear end portion of the pressure plate 3 in the left-right direction. The shaft hole communicates with the rectangular grooves 32 to 34.

[0083] The pressure plate 3 has a lower surface 35 configured to face the upper surface 21 of the base plate 2 when the pressure plate 3 is in the closed position. The lower surface 35 is provided with a raised portion 36, pressure ribs 37, and four magnetic bodies 381, 382, 383, and 384. In a bottom view of the pressure plate 3, the raised portion 36 has a generally rectangular shape that is elongated in the left-right direction. The raised portion 36 is positioned closer to the rear end of the lower surface 35 than to the front end. When the pressure plate 3 is in the closed position, the raised portion 36 protrudes downward from the lower surface 35.

[0084] The pressure rib 37 extends along the front end of the lower surface 35. When the pressure plate 3 is in the closed position, the pressure rib 37 protrudes downward. The pressure rib 37 protrudes from the lower surface 35 by a slightly larger amount than the protrusion of the convex portion 36.

[0085] The four magnetic bodies 381 to 384 are located between the convex portion 36 and the pressure rib 37 in the front-rear direction. Each of the magnetic bodies 381 to 384 has a disk shape and is arranged at a position corresponding to the position of each of the magnets 271 to 274 provided on the upper surface 21 of the substrate 2.

[0086] To assemble the pressure plate 3 to the base plate 2, the hinges 22 and 23 of the base plate 2 are inserted into the rectangular grooves 32 and 33, respectively, so that the axial holes of the pressure plate 3 are aligned with the axial holes of the hinges 22 and 23. Pivot 5A is inserted into the axial hole of the pressure plate 3 from the right end thereof, extending into the axial hole of the hinge 22. Another pivot 5B is inserted into the axial hole of the pressure plate 3 from the left end thereof, extending into the axial hole of the hinge 23. In this way, the rear end of the pressure plate 3 is connected to the rear end of the base plate 2 via the pivots 5A and 5B, allowing the pressure plate 3 to pivotally move relative to the base plate 2 about the axes of the pivots 5A and 5B.

[0087] Next, the opening and closing operations performed in the clamp 1 will be described.

[0088] like Figures 1 to 3 As shown in , when the pressure plate 3 is in the closed position relative to the base plate 2, the convex portion 36 of the pressure plate 3 is located directly above the area of the upper surface 21 of the base plate 2, which is behind the first ribs 251 to 255; and the lower end surface of the pressure rib 37 is in contact with the upper surface 21 of the base plate 2. Figure 3 and Figure 9 As shown in FIG, the lower end of the pressure rib 37 is located slightly forward of each rear end of each of the rectangular recesses 291 to 293.

[0089] When the pressure plate 3 at the closed position is pivoted rearward relative to the base plate 2 about the axis of the pivot shafts 5A, 5B, the pressure plate 3 is moved to the open position. Figures 4 to 6 . At this time, the pressure plate 3 is tilted rearward relative to the base plate 2. As the pressure plate 3 pivots rearward from the closed position to the open position, the lower end of the mating engagement plate 341 engages with the rear surface of the engagement protrusion 24. Thus, the pressure plate 3 can maintain its tilted position at an oblique angle relative to the base plate 2.

[0090] Next, we will refer to Figure 7 The structure of the stack label 10 will be described.

[0091] The stacked label 10 is produced by combining multiple labels in a stacked relationship. In this embodiment, the stacked label 10 is constructed from a lower label 11 and an upper label 12. The printed image that appears on the stacked label 10 is based on a base image desired by the user. The base image is divided into two printed images, and each printed image is printed on a tape for each label 11, 12 by a label printer (not shown).

[0092] Incidentally, the tape used for each label 11, 12 is an adhesive tape comprising a peeling sheet. The peeling sheet has a straight cutting line P (see FIG. Figure 8), the straight cut line P extending along the widthwise centerline of the release sheet. The release sheet can be divided into two sections along the straight cut line P relative to the width of the release sheet. In this embodiment, the lower label 11 is the base label, and the upper label 12 is superimposed on top of the lower label 11 and adhered thereto. The clamp 1 according to this embodiment is configured to provide accurate and easy positioning of the upper label 12 on top of the lower label 11, and to adhere the accurately positioned upper label 12 to the lower label 11.

[0093] Next, we will refer to Figures 8 to 12 A method for creating the stacked label 10 using the jig 1 according to the present embodiment is described.

[0094] First, the user prints on each of the lower label 11 and the upper label 12 using a label printer (not shown) to prepare a printed lower label 11 and a printed upper label 12. The user opens the jig 1 and places the lower label 11 and the upper label 12 on the label placement area 211 of the upper surface 21 of the substrate 2 so that Figure 8 As shown in FIG, the upper label 12 is laid over the lower label 11. Then, the user brings the respective rear edges of the lower label 11 and the upper label 12 into abutment with the first ribs 251 to 255. The respective right edges of the lower label 11 and the upper label 12 superimposed on the lower label 11 (more specifically, the right edge 11B of the lower label 11) Figures 10 to 11B ) and the right edge 12B of the upper label 12 ( Figures 9 to 11B )) then comes into abutment with the second rib 26 on the upper surface 21 of the base plate 2. Therefore, the positions of the right rear corners of the lower label 11 and the upper label 12 are aligned with each other, and therefore, the outline of the lower label 11 can be easily aligned with the outline of the upper label 12.

[0095] Then, in a state where the outlines of the lower label 11 and the upper label 12 are aligned with each other on the label placement area 211, the user pivotally moves the pressure plate 3 toward the upper surface 21 of the base plate 2 to close the clamp 1 (see FIG. Figure 9 As a result, on the label placement area 211 of the upper surface 21 of the base plate 2, the lower label 11 and the upper label 12 are pressed from above by the pressure ribs 37 of the pressure plate 3.

[0096] At this time, the four magnetic bodies 381 to 384 on the lower surface 35 of the pressure plate 3 are magnetically attracted to the four magnets 271 to 274 on the upper surface 21 of the base plate 2. Therefore, since the magnets 271 to 274 are positioned along the rear end portion of the label placement area 211, the rear end portions of the lower label 11 and the upper label 12 are tightly clamped between the magnetic bodies 381 to 384 and the magnets 271 to 274. In this state, a portion of the peripheral portion of the upper label 12 (specifically, the portion includes: the front end portion including the front edge 12A; and the right front corner portion including the right edge 12B but not including the right rear corner portion of the upper label 12) is exposed to the outside of the clamp 1, as shown in FIG. Figure 9 As shown in .

[0097] Here, the peripheral portion of the upper label 12 means the entire peripheral edge portion of the upper label 12. That is, the peripheral portion means the outer edge (outline) of the upper label 12 and the surface of the upper label 12 that can be seen in a plan view (that is, when viewed in a direction perpendicular to the surface of the upper label 12). The front edge 12A and the right edge 12B are part of the outline of the upper label 12.

[0098] like Figure 8 As shown in FIG, the length L1 of the label placement area 211 in the front-to-back direction is shorter than the length L2 of the lower label 11 and the upper label 12 in the front-to-back direction (i.e., the width). Preferably, the length L1 of the label placement area 211 is shorter than half the length L2 of the lower label 11 and the upper label 12 (in the width). Figure 8 Therefore, the cutting line P formed on the peeling sheet of each of the upper label 12 and the lower label 11 is located in front of the front edge of the upper surface 21 of the substrate 2 (see FIG. Figure 8 and Figure 9 ).

[0099] That is, the area of the upper label 12 between the front edge 12A and the cut line P in the front-to-back direction is located in front of the base plate 2 and therefore protrudes forward from the base plate 2. This area of the upper label 12 is included in the exposed portion of the peripheral portion of the upper label 12, which includes: the front end portion of the upper label 12 (front edge 12A); and the right front corner of the upper label 12, excluding the right rear corner thereof. Therefore, the user can easily flip this exposed area of the upper label 12 upward relative to the lower label 11.

[0100] Here, preferably, the exposed portion of the peripheral portion of the upper label 12 includes: a front end portion including the front edge 12A; and a portion including the right edge 12B and excluding the right rear corner portion, so that the front end portion of the upper label 12 (the front end portion is opposite to the rear end portion clamped between the base plate 2 and the pressure plate 3) becomes the free end portion of the upper label 12. With this configuration, since the right front corner portion of the upper label 12 defined by the front edge 12A and the right edge 12B is included in the exposed portion, the user can flip upward the exposed free end portion (free end portion) of the upper label 12 including the right front corner portion.

[0101] like Figure 11B As shown in , the user flips upward only the front end of the upper label 12 relative to the lower label 11. Since the area of the upper label 12 from the front edge 12A to the cut line P is exposed and protrudes relative to the base plate 2, the release sheet of the upper label 12 is divided into a front half section and a rear half section at the cut line P due to the tension (or linearity) of the release sheet itself. As a result, the corresponding cut edges 121 and 122 of the front half section and the rear half section are separated from the adhesive sheet of the upper label 12. The user then peels the front half section of the release sheet from the adhesive sheet and secures the front half of the adhesive sheet of the upper label 12 (from which the front half section of the release sheet was peeled) to the upper surface of the lower label 11.

[0102] Then, with the front end portion of the upper label 12 bonded to the lower label 11, the user removes the lower label 11 and the upper label 12 together from the clamp 1. At this time, since the front end portion of the upper label 12 is bonded to the lower label 11, the positional relationship between the lower label 11 and the upper label 12 is maintained. Then, the user peels off the rear half section of the peeling sheet from the adhesive sheet of the upper label 12, and bonds the rear half section (peeling section) of the adhesive sheet of the upper label 12 to the upper surface of the lower label 11. In this way, by adopting the clamp 1, the lower label 11 and the upper label 12 are adhered to each other with their contours aligned with each other. Therefore, the user can easily create the stacked label 10 using the clamp 1 according to the present embodiment.

[0103] As described above, the lower label 11 and the upper label 12 of the present embodiment have such a width that the front end portions of the labels 11 and 12 protrude forward relative to the label placement area 211 of the substrate 2. Here, it is assumed that the upper label and the lower label, whose width is smaller than the width (front-to-back length) of the label placement area 211, are clamped by the clamp 1. In this case, the front edges of the upper label and the lower label are located behind the front edge of the label placement area 211. However, at this time, the front end portions (front edges) of the upper label and the lower label are located directly above the rectangular recesses 291 to 293 on the upper surface 21 of the substrate 2.

[0104] Therefore, a gap is formed between the front end of the upper and lower labels and the bottom surface of each rectangular recess 291 to 293, so that the user can insert his fingers into the gap to hook the front end of the upper and lower labels. Through the gap, the user can insert his fingers to hook the front end of the upper label and the front end of the lower label, respectively, so that the user can easily flip the front end of the upper label 12 upward from the lower label 11.

[0105] As described above, the clamp 1 according to the first embodiment is used to adhere the upper label 12 to the lower label 11 after the upper label 12 is stacked on top of the lower label 11 in the thickness direction of the labels 11 and 12. Each of the lower label 11 and the upper label 12 includes an adhesive sheet and a peeling sheet adhered to the adhesive sheet. The clamp 1 includes a substrate 2 and a pressure plate 3. On the upper surface 21 of the substrate 2, there are provided a first rib 25 (251 to 255) and a second rib 26. The first rib 25 (251 to 255) is configured to be contacted by the rear edges of the lower label 11 and the upper label 12 stacked on each other, thereby serving to limit the corresponding positions of the rear edges of the upper label 12 and the lower label 11. The second rib 26 is configured to be contacted by the right edge 12B of the upper label 12 and the right edge 11B of the lower label 11, thereby serving to limit the corresponding positions of the right edges 12B, 11B of the upper label 12 and the lower label 11. The base plate 2 and the pressure plate 3 are configured to sandwich rear end portions of the upper label 12 and the lower label 11 stacked on each other in their thickness directions to fix their positions.

[0106] In this way, since the rear edge and right edge of the upper label 12 can be actually aligned with the rear edge and right edge of the lower label 11 in an overlapping relationship, the clamp 1 can accurately and easily make the edges of the upper label 12 and the lower label 11 flush in two directions perpendicular to each other. The clamp 1 is configured to clamp the rear end portions of the upper label 12 and the lower label 11 aligned with each other from both sides of the labels 12, 11 in the thickness direction to fix the positions of the upper label 12 and the lower label 11. Therefore, even if the user flips the front end portion of the upper label 12 upward from the lower label 11, positional shift of the upper label 12 relative to the lower label 11 does not occur. The user flips the front end portion of the upper label 12 upward, peels off the front half section of the peel-off sheet, and bonds the front half area of the adhesive sheet of the upper label 12 to the lower label 11. Then, the user removes the upper label 12 and the lower label 11 from the clamp 1. After removing the upper and lower labels 12 and 11 from the jig 1 , the user can peel off the rear half section of the release sheet and bond the rear half area (peel area) of the adhesive sheet of the upper label 12 to the lower label 11 to create the stacked label 10 .

[0107] In the clamp 1 according to the first embodiment, the upper surface 21 of the base plate 2 is provided with four magnets 271 to 274, and the lower surface 35 of the pressure plate 3 is provided with four magnetic bodies 381 to 384. Therefore, the clamp 1 can firmly clamp the rear end portions of the stacked upper and lower labels 12 and 11 in the thickness direction of the labels 11, 12 by the magnetic force of the magnets 271 to 274.

[0108] In the clamp 1, the base plate 2 and the pressure plate 3 are pivotally connected to each other by hinges 22 and 23, allowing the clamp 1 to be opened and closed. Thus, the base plate 2 and the pressure plate 3 can provide a uniform clamping force along the length of the clamp 1. Furthermore, since the hinges 22 and 23 prevent separation between the base plate 2 and the pressure plate 3, the clamp 1 can be provided with enhanced portability.

[0109] The upper surface 21 of the base plate 2 provides a label placement area 211. When the pressure plate 3 is closed relative to the base plate 2, only the rear ends of the upper label 12 and the lower label 11, which are stacked and placed on the label placement area 211, are clamped between the base plate 2 and the pressure plate 3. That is, when the pressure plate 3 is closed relative to the base plate 2, the base plate 2 faces a limited area (including the rear end) of the lower label 11 placed on the label placement area 211, and the pressure plate 3 faces a limited area (including the rear end) of the upper label 12 placed on the label placement area 211. This structure allows the user to easily attach the upper label 12 to the lower label 11, since they can simply flip the upper label 12 upward to peel off the front half of the peel-off sheet.

[0110] In the above embodiment, the upper label 12 and the lower label 11 have the same shape and size as each other. However, only a portion of the upper label 12 may have the same shape and size as the corresponding portion of the lower label 11. Alternatively, the size of the upper label 12 can be determined to be within the area of the lower label 11 (that is, the size of the upper label 12 as a whole can be smaller than the lower label 11). Still alternatively, the portions of the upper label 12 and the lower label 11 whose shapes and sizes are consistent with each other can abut against the first ribs 251 to 255 and the second rib 26, thereby limiting the corresponding positions of the upper label 12 and the lower label 11. Therefore, the upper label 12 and the lower label 11 can be stacked on each other with accurate position alignment therebetween.

[0111] Regarding the first embodiment, the upper label 12 is an example of the "first sheet" of the present disclosure. The lower label 11 is an example of the "second sheet". The rear edges of the upper label 12 and the lower label 11 stacked on each other are examples of the "first edge" and the "second edge", respectively. The right edges 12B and 11B of the upper label 12 and the lower label 11 stacked on each other are examples of the "third edge" and the "fourth end area", respectively. The first ribs 25 (251 to 255) and the second ribs 26 provided on the upper surface 21 of the substrate 2 are examples of the "first limiting portion" and the "second limiting portion", respectively. The substrate 2 and the pressure plate 3 are examples of a "clamp" and a "pair of adjacent portions". The substrate 2 is also an example of a "second adjacent portion". The pressure plate 3 is also an example of a first adjacent portion. The label placement area 211 on the upper surface 21 of the substrate 2 is an example of a "placement area". The hinges 22 and 23 are examples of a "hinge portion". The cutting line P is an example of a "cutting line". The magnets 271 to 274 and the magnetic bodies 381 to 384 are examples of a “pressing force applying portion”.

[0112] <Second embodiment>

[0113] Next, we will refer to Figures 12 to 15 A second embodiment of a jig 200 is described in which the same parts and components as those of the second embodiment are replaced by the same parts and components as those of the second embodiment. Figures 1 to 11B The same reference numerals as those of the first embodiment shown in FIG. 1 are used to avoid repeated description.

[0114] In the jig 1 according to the first embodiment, the pressure plate 3 is pressed against the base plate 2 by the magnetic force of the magnets 271 to 274 for closing the pressure plate 3. In contrast, the jig 200 according to the second embodiment does not include the magnets 271 to 274 nor the magnetic bodies 381 to 384 ( Figure 4 ). Instead, the clamp 200 of the second embodiment includes a helical torsion spring 260, and the clamp 200 is closed by the urging force of the helical torsion spring 260.

[0115] like Figure 12 As shown in , the clamp 200 includes a base plate 220 and a pressure plate 230. The base plate 220 has substantially the same construction as the base plate 2 of the first embodiment. However, the magnets 271 to 274 are not provided on the upper surface 21 of the base plate 220. The pressure plate 230 has at least partially a structure in common with the pressure plate 3 of the first embodiment. However, the magnetic bodies 381 to 384 are not provided on the lower surface 235 of the pressure plate 230. As in the first embodiment, the pressure plate 230 is pivotally movably connected to the base plate 220 by the hinges 22 and 23 of the base plate 220. However, the pivotally movable stroke of the pressure plate 230 around the axis of the pivot 5A is limited within a predetermined range and is smaller than the stroke of the pressure plate 3 of the first embodiment. As Figure 15As shown in FIG, even at the open position of the pressure plate 230, the lower end surface of the pressure rib 37 of the pressure plate 230 is located below the upper end of the first rib 25 provided on the upper surface 21 of the base plate 220.

[0116] Specifically, the pressure plate 230 includes a rod 240 having a generally U-shape. Figure 13 As shown in FIG, the lever 240 has a base end portion located below the front end portion of the pressure plate 230 and is rotatably supported by a pivot 242 provided on the base plate 220. Thus, the lever 240 is pivotally movable about the axis of the pivot 242. The pivot 242 extends in the left-right direction and is supported by the base plate 220 at a position above the upper surface 21. The pivot 242 is located forward of the pivot 5A.

[0117] The base end portion of the rod 240 includes a sleeve portion 241 extending along a pivot 242. The sleeve portion 241 has an outer peripheral surface, and a cam 245 is provided at an upper portion of the outer peripheral surface. The cam 245 protrudes radially outward from the outer peripheral surface. A protrusion 231 is provided on the front end portion of the lower surface 235 of the pressure plate 230 so as to protrude downward from the front end portion of the lower surface 235 at a position corresponding to the position of the sleeve portion 241. Figure 12 and Figure 13 As shown in FIG, in a state where the lever 240 is pressed downward, the cam 245 is located behind the protrusion 231.

[0118] A coiled torsion spring 260 is positioned above the support shaft 5A. The coiled torsion spring 260 has one end positioned on the upper surface 21 of the base plate 220 and the other end positioned on the lower surface 235 of the pressure plate 230. Thus, the coiled torsion spring 260 normally pushes the rear portion of the pressure plate 230 upward, causing the pressure ribs 37 at the front portion of the pressure plate 230 to be pressed against the upper surface 21 of the base plate 220. That is, when no external force is applied thereto, the pressure plate 230 is normally in the closed position.

[0119] like Figure 14 and Figure 15As shown in , in the right side view, pulling the rod 240 upward causes the sleeve portion 241 to rotate angularly in the counterclockwise direction, so that the cam 245 pushes the protrusion 231 upward and moves in front of the protrusion 231. Therefore, the pressure plate 230 overcomes the urging force of the spiral torsion spring 260 and pivotally moves around the axis of the pivot 5A in the clockwise direction (in the right side view). As a result, the front end portion of the pressure plate 230 is moved upward, and the pressure rib 37 is lifted upward to separate from the upper surface 21 of the base plate 220. At this time, the length of the gap between the upper surface 21 and the lower surface of the pressure rib 37 is adjusted to be greater than the sum of the thicknesses of the lower label 11 and the upper label 12. In this state, the lower surface of the pressure rib 37 is positioned lower than the upper end surface (top surface) of the first rib 25.

[0120] While the user pulls up the lever 240 to maintain the front end of the pressure plate 230 in the raised position (to maintain the pressure plate 230 in the open position), the user places the upper label 12 and the lower label 11 on the label placement area 211 of the upper surface 21 of the base plate 220, positioning them so that the upper label 12 and the lower label 11 abut against the first ribs 25 (251 to 255) and the second ribs 26. The user then pushes the lever 240 downward, thereby moving the cam 245 to a position behind the protrusion 231, causing the front end of the pressure plate 230 to move downward due to the urging force of the helical torsion spring 260. Consequently, the pressure ribs 37 press the rear ends of the stacked upper and lower labels 12, 11 against the upper surface 21. Thus, similar to the first embodiment, the clamp 200 according to the second embodiment is capable of clamping the lower label 11 and the upper label 12 between the base plate 220 and the pressure plate 230.

[0121] In the clamp 200 according to the second embodiment, even when the pressure plate 230 is in the open position, that is, even when the front end portion of the pressure plate 230 is raised in response to the user pulling the lever 240 upward, the lower surface of the pressure rib 37 is positioned lower than the upper end surface of the first rib 25. With this structure, the rear edges of the lower label 11 and the upper label 12 cannot move on the first rib 25. Therefore, accurate abutment of the rear edges of the lower label 11 and the upper label 12 on the first rib 25 can be achieved.

[0122] With respect to the second embodiment, the coil torsion spring 260 is an example of a “pressing force applying portion”.

[0123] <Third embodiment>

[0124] Will refer to Figure 16 A clamp 300 according to a third embodiment is described, wherein the same parts and components are used as in the Figures 1 to 11B The same reference numerals as those of the first embodiment shown in FIG. 1 are used to avoid repeated description.

[0125] In the jig 1 according to the first embodiment, the base plate 2 and the pressure plate 3 are pivotally connected to each other by hinges 22 and 23. In contrast, the jig 300 according to the third embodiment has an elastic clamping structure constructed of a base plate 320 and a pressure plate 330 integral with each other.

[0126] The base plate 320 of the third embodiment differs from the base plate 2 of the first embodiment in that neither the magnets 271 to 274 nor the hinges 23 and 22 are provided on the upper surface 21 of the base plate 320. Consequently, the magnetic bodies 381 to 384 of the first embodiment are not provided on the lower surface of the pressure plate 330. The rear end of the pressure plate 330 is directly connected to the rear end of the base plate 320, forming a generally U-shaped shape in side view. The base plate 320 and the pressure plate 330 are integrally molded from resin. Due to the elasticity of the integral resin product, the pressure ribs 37 of the pressure plate 330 are normally pressed against the upper surface 21 of the base plate 320.

[0127] The user holds the base plate 320 with one hand and uses the other hand to pull upward on the operating portion 31, located at the front end of the pressure plate 330, against the elastic force. Consequently, the pressure ribs 37 separate from the upper surface 21 of the base plate 320 and move upward. The user then places the lower label 11 and the upper label 12 on the label placement area 211 of the upper surface 21 of the base plate 320, securing the positions of the two labels 11 and 12 along the first and second ribs 25 and 26. As the user gradually releases the upward pulling force applied to the operating portion 31, the clamp 300 returns to its original shape due to the elasticity of the resin. The pressure ribs 37 press the rear ends of the lower label 11 and the upper label 12 against the upper surface 21. Thus, similar to the first and second embodiments, the clamp 300 according to the third embodiment is able to clamp the lower label 11 and the upper label 12 between the base plate 320 and the pressure plate 330.

[0128] <Fourth embodiment>

[0129] Will refer to Figures 17A to 21B A clamp 400 according to a fourth embodiment is described, wherein the same parts and components are used as in the Figures 1 to 11B The same reference numerals as those of the first embodiment shown in FIG. 1 are used to avoid repeated description.

[0130] In the jig 1 according to the first embodiment, the pressure plate 3 is urged toward the base plate 2 in a direction for closing the pressure plate 3 by utilizing the magnetic force of the magnets 271 to 274. In contrast, the jig 400 according to the fourth embodiment adopts a toggle mechanism to urge the pressure plate 430 toward the base plate 420 to close the pressure plate 430.

[0131] like Figure 17AAs shown in FIG, the base plate 420 has a structure similar to that of the base plate 2 of the first embodiment, but the base plate 420 differs from the base plate 2 in that the upper surface 21 of the base plate 420 is not provided with the magnets 271 to 274. The pressure plate 430 has a structure similar to that of the pressure plate 3 at least in part. However, the magnetic bodies 381 to 384 of the first embodiment are not provided on the lower surface of the pressure plate 430. In addition, the pressure plate 430 is pivotally connected to the base plate 420 by the hinges 22 and 23 of the base plate 420. However, the pivotable travel of the pressure plate 430 about the axis of the pivot 5A (the axis of the pivot 5B) is limited to a predetermined range and is smaller than the travel of the pressure plate 3.

[0132] The jig 400 of the fourth embodiment includes a lever 440 for pivotally moving the pressure plate 430 relative to the base plate 320 .

[0133] Specifically, in the jig 400 according to the fourth embodiment, as shown in FIG. Figure 17A As shown in FIG, the boss 421 stands from the upper surface 21 of the base plate 420 at the central portion of the upper surface 21 in the left-right direction. The rotation shaft 441 extending in the left-right direction is supported by the upper portion of the boss 421 (see FIG. Figure 17B ). The rotation axis 441 is located in front of the corresponding pivot shafts 5A and 5B.

[0134] The rod 440 has a generally rectangular plate-like shape. Figure 17B The rod 440 has a base end portion located below the front end portion of the pressure plate 430 and is rotatably supported by a rotation shaft 441. In addition, a link member 450 having an elongated elliptical shape in a side view is connected to the base end portion of the rod 440 and the pressure plate 430.

[0135] Specifically, the first connecting pin 452 extends outward in the left-right direction from the base end portion of the rod 440. The first connecting pin 452 is located below the rotation shaft 441. One longitudinal end portion of the link member 450 is rotatably connected to the first connecting pin 452.

[0136] The connecting plate 460 extends rearward from the front end portion of the lower surface of the pressure plate 430. The connecting plate 460 is located behind the pressure rib 37. The second connecting pin 451 extends outward in the left-right direction from the rear end portion of the connecting plate 460. The other longitudinal end portion of the link member 450 is rotatably connected to the second connecting pin 451. That is, the pressure plate 430 is connected to the rod 440 through the link member 450. The rotation shaft 441, the link member 450, the first connecting pin 452, and the second connecting pin 451 in combination constitute a toggle mechanism that is configured to allow the pressure rib 37 of the pressure plate 430 to be pressed against the upper surface 21 of the base plate 420 according to the user's operation of the rod 440.

[0137] like Figure 17A As shown in FIG, when the rod 440 is in the upwardly pulled position, the first connecting pin 452 is located behind the rotating shaft 441 and the second connecting pin 451. That is, the combination of the first line segment connecting the rotating shaft 441 to the first connecting pin 452 and the second line segment connecting the first connecting pin 452 to the second connecting pin 451 forms an L-shaped shape that bends at the first connecting pin 452. At this time, the combination of the link member 450 and the connecting plate 460 forms a generally V-shaped shape that bends at the second connecting pin 451. As a result, the front end of the pressure plate 430 is lifted by the connecting plate 460. As a result, the pressure ribs 37 of the pressure plate 430 move upward away from the upper surface 21 of the base plate 420. As a result, the compressive force from the pressure ribs 37 on the upper surface 21 of the base plate 420 is released.

[0138] In this state, the user places the lower label 11 and the upper label 12 in an overlapping relationship on the label placement area 211 of the upper surface 21 of the base plate 420, and positions the lower label 11 and the upper label 12 relative to the first rib 25 and the second rib 26. Then, the user pushes the lever 440 downward, as shown in FIG. Figure 18B and Figure 19B As shown in FIG, this allows the lever 440 to pivotally move in the clockwise direction about the rotation axis 441 in the right side view, so that the first connecting pin 452 is moved forward.

[0139] At this time, in the right side view, the link member 450 pivotally moves counterclockwise about the first connecting pin 452. As a result, the second connecting pin 451 is displaced rearward and diagonally downward. As a result, the angle defined between the link member 450 and the connecting plate 460 gradually decreases, moving the pressure plate 430 downward toward its closed position.

[0140] Then, if Figure 20A and Figure 20B As shown in , when the pressure plate 430 is at its bottom dead center, the rotation axis 441 connecting the rod 440 to the boss 421, the first connecting pin 452 connecting the rod 440 to the link member 450, and the second connecting pin 451 of the connecting plate 460 connecting the link member 450 to the pressure plate 430 are arranged in a straight line. That is, the first line segment (the first line segment connecting the rotation axis 441 to the first connecting pin 452) and the second line segment (the second line segment connecting the first connecting pin 452 to the second connecting pin 451) are arranged in a straight line. At this time, a sufficiently large pressing force is applied to the pressure plate 430, and therefore, the pressure ribs 37 are able to cooperate with the upper surface 21 of the base plate 420 to clamp the rear ends of the lower label 11 and the upper label 12.

[0141] In addition, if Figure 21A and Figure 21BAs shown in , even after the pressure plate 430 reaches the bottom dead center, the rod 440 is able to move slightly further downward. Therefore, when the rod 440 is pushed downward to its lowest position, even if a reaction force is generated from the pressure plate 430 (the reaction force is in the direction for opening the pressure plate 430), the lowest position of the rod 440 can still be maintained because a force that pushes the rod 440 downward is applied to the rod 440 by the link member 450. Therefore, the pressure rib 37 presses the rear end portions of the lower label 11 and the upper label 12 against the upper surface 21. Therefore, similar to the first to third embodiments, the clamp 400 according to the fourth embodiment is able to clamp the lower label 11 and the upper label 12 between the base plate 420 and the pressure plate 430.

[0142] Regarding the fourth embodiment, the rotating shaft 441 , the link member 450 , the second connecting pin 451 , and the first connecting pin 452 constituting the toggle mechanism are examples of a “pressing force applying portion.” The lever 440 is an example of an “operating portion.”

[0143] <Fifth embodiment>

[0144] Will refer to Figures 22 to 27 A clamp 500 according to a fifth embodiment is described, wherein the same parts and components are used as in the Figures 1 to 11B The same reference numerals as those of the first embodiment shown in FIG. 1 are used to avoid repeated description.

[0145] In the jig 1 according to the first embodiment, the magnetic force of the magnets 271 to 274 is used to push the pressure plate 3 toward the base plate 2 to close the pressure plate 3. In contrast, the jig 500 according to the fifth embodiment adopts a cam mechanism for pushing the pressure plate 530 toward the base plate 520 to close the pressure plate 530.

[0146] like Figure 23 As shown in FIG, the substrate 520 has a structure similar to that of the substrate 3 of the first embodiment. However, the magnets 271 to 274 are not provided on the upper surface 21 of the substrate 520. Specifically, similarly to the first embodiment, the hinges 22 and 23, the rectangular recesses 291 to 293, the first rib 25 and the second rib 26 are provided on the upper surface 21 of the substrate 520. Here, as Figure 23 As shown in FIG, the first rib 25 of the fifth embodiment is a single straight elongated rib extending in the left-right direction, rather than the plurality of ribs 251 to 255 of the first embodiment.

[0147] Furthermore, in the front-rear direction, a coil spring 525 is interposed between the hinge 22 and the first rib 25, and another coil spring 526 is interposed between the hinge 23 and the first rib 25. A boss 521 stands upright from the base plate 520 at a position between the coil springs 525 and 526 in the left-right direction. The boss 521 supports a rotation shaft 542 extending in the left-right direction (see FIG. Figure 26 ).

[0148] like Figure 22 and Figure 24 As shown in FIG, pressure plate 530 has a structure similar to base plate 3 of the first embodiment, but the lower surface of base plate 530 is not provided with magnetic bodies 381 to 384 of the first embodiment. Furthermore, pressure plate 530 is pivotally connected to base plate 520 via hinges 22 and 23 of base plate 520, thereby being movable between an open position and a closed position. However, the pivotal travel of pressure plate 530 about the axis of pivot 5A (the axis of pivot 5B) is limited to a predetermined range and is smaller than the travel of pressure plate 3. Therefore, even in the open position of pressure plate 530, at least a portion of first rib 25 and second rib 26 provided on upper surface 21 of base plate 520 is normally covered by pressure plate 530.

[0149] The pressure plate 530 is usually pushed upward by the coil springs 525 and 526 located on the upper surface 21 of the base plate 520. Therefore, the front end of the pressure plate 530 is usually lifted upward. The pressure plate 530 has a groove 531 (see FIG. Figure 26 ) on the front end portion.

[0150] The clamp 500 further includes a rod 540 having a generally rectangular plate-like shape. Figure 23 and Figure 26 As shown in FIG, a pair of acting portions 541 are provided, one at each of the left and right ends of the base end portion of the rod 540. Each of the left and right acting portions 541 has a generally cylindrical shape extending in the left-right direction and is rotatably supported by a rotating shaft 542 supported by the boss 521. A cam portion 545 protrudes radially outward from the outer peripheral surface of each acting portion 541 (see FIG. Figure 26 and Figure 27 The acting portion 541 is located inside a groove 531 formed in the pressure plate 530. Each cam portion 545 has an arcuate surface centered on the axis of the rotating shaft 542 and projecting radially outward.

[0151] like Figure 25 and Figure 26 As shown in FIG, when the lever 540 is pulled upward, each cam portion 545 located in the groove 531 faces rearward (protrudes rearward). At this time, the pressure plate 530 is urged upward by the coil springs 525 and 526 located on the upper surface 21 of the base plate 520. As a result, the pressure ribs 37 of the pressure plate 530 are lifted away from the upper surface 21 of the base plate 520. Thus, the clamp 500 can maintain a released state in which the upper surface 21 of the base plate 520 is not affected by the pressure from the pressure ribs 37.

[0152] The user places the lower label 11 and the upper label 12 on the label placement area 211 of the upper surface 21 of the substrate 520 so that the lower label 11 and the upper label 12 are positioned relative to the first rib 25 and the second rib 26 .

[0153] The user then pushes lever 540 downward, overcoming the urging force of coil springs 525 and 526. At this time, each acting portion 541 is angularly rotated to pivotally move cam portion 545 downward. As a result, the corresponding cam portion 545 pushes the bottom of groove 531 downward. Thus, pressure plate 530 pivotally moves downward about pivots 5A and 5B, overcoming the urging force of coil springs 525 and 526. This causes pressure ribs 37 provided at the front end of pressure plate 530 to press the rear ends of upper label 12 and lower label 11 against upper surface 21. The static friction force generated by the contact between the arcuate surface of each cam portion 545 and the bottom of groove 531 maintains the pressure from pressure ribs 37 against upper surface 21.

[0154] The amount of downward movement of the pressure rib 37 depends on the amount of downward movement of the cam portion 545 (how much the cam portion 545 pushes the groove 531 downward), which in turn depends on the amount of downward pivotal movement of the lever 540. With this structure, the clamp 500 of the fifth embodiment can appropriately adjust the clamping force relative to the lower label 11 and the upper label 12. Therefore, similar to the first to fourth embodiments, the clamp 500 according to the fifth embodiment can clamp the lower label 11 and the upper label 12 between the base plate 520 and the pressure plate 530.

[0155] Similar to the second to fourth embodiments, according to the clamp 500 of the fifth embodiment, even when the front end portion of the pressure plate 530 is lifted upward due to the user pulling the lever 540 upward (even when the pressure plate 530 is at the open position), the lower end surface of the pressure rib 37 of the pressure plate 530 is positioned lower than the upper end surface of the first rib 25 on the upper surface 21 of the base plate 520 (see FIG. Figure 26 ). Therefore, when the lower label 11 and the upper label 12 are stacked and placed on the label placement area 211, the rear edges of the lower label 11 and the upper label 12 cannot move on the first rib 25. Therefore, it is possible to achieve accurate abutment of the rear edges of the lower label 11 and the upper label 12 against the first rib 25.

[0156] Regarding the fifth embodiment, the acting portion 541 , the cam portion 545 , and the groove 531 constituting the cam mechanism are examples of a “pressing force applying portion.” The lever 540 is an example of an “operating portion.”

[0157] <Variants and variants>

[0158] The clamp according to the present disclosure is not limited to the above-described first to fifth embodiments, but various changes and modifications may be made without departing from the scope of the present disclosure.

[0159] For example, the entire pressure plate 3 of the first embodiment may be made of a transparent resin. 28A to 28D A jig 600 is shown, which includes a transparent pressure plate 630 and the substrate 2 of the first embodiment. Alternatively, a portion of the pressure plate 3 may be made of a transparent resin, the portion corresponding to at least the first ribs 251 to 255 and the second rib 26. Similar modifications can be made with respect to the pressure plates 230, 330, 430, and 530 of the second to fifth embodiments.

[0160] In the first embodiment, instead of providing five first ribs 251 to 255 on the upper surface 21 of the substrate 2, a plurality of strip-shaped pins may be arranged in a straight line at intervals on the upper surface 21. In the latter case, the protruding length of each pin from the upper surface 21 should be greater than the total thickness of the lower label 11 and the upper label 12. In addition, instead of a plurality of first ribs, an elongated single first rib (such as Figure 23 ). In addition, the number of the first ribs 25 does not need to be five as in the first embodiment. The number and shape of the second ribs 26 can also be changed in the same manner as the variation in which the five first ribs 251 to 255 are available.

[0161] In the first embodiment, the label placement area 211 is defined by five first ribs 251 to 255 and the second rib 26. Alternatively, the label placement area 211 may be provided on the upper surface 21 of the substrate 2 in the form of a downward step. In the latter case, the height difference between the upper surface 21 and the downward step (label placement area 211) may form a "first limiting portion" (serving as the first ribs 251 to 255) and a "second limiting portion" (instead of the second rib 26). The height (length) of the height difference should be greater than the total thickness of the lower label 11 and the upper label 12. The same modifications may be made with respect to the substrates 220, 320, 420, and 520 of the second to fifth embodiments.

[0162] In the first embodiment, the first ribs 251 to 255 are used to provide positioning for the rear edges of the lower label 11 and the upper label 12 that are stacked on each other, and the second rib 26 is used to provide positioning for the right edges of the lower label 11 and the upper label 12. However, the lower label 11 and the upper label 12 may not have a strip-like shape, but may have a shape other than a strip-like shape, such as, for example, a triangular shape, a circular shape, or a diamond shape. If this is the case, a point on the edge (contour) of the lower label 11 and the upper label 12 may be adjacent to the first rib, and another point on the edge of the lower label 11 and the upper label 12 may be adjacent to the second rib. Here, the other point is at a position where it can contact a tangent that intersects the tangent that contacts the first point.

[0163] For example, Figure 29A An example is shown in which the lower label 110 and the upper label 120 have an elliptical shape. In this way, a first point A1 on the edge E of the lower label 110 and the upper label 120 can abut on a first rib providing a tangent line L1, and a second point A2 on the edge E of the lower label 110 and the upper label 120 can abut on a second rib providing a tangent line L2 perpendicular to the tangent line L1.

[0164] Alternatively, as Figure 29B As shown in FIG, the orientation of the lower label 110 and the upper label 120 is Figure 29A In different cases, a first point A3 on the edge E of the lower label 110 and the upper label 120 can be adjacent to a first rib providing a tangent line L3, and a second point A4 on the edge E of the lower label 110 and the upper label 120 can be adjacent to a second rib providing a tangent line L4 perpendicular to the tangent line L3.

[0165] Furthermore, alternatively, the first and second ribs may not be oriented perpendicular to each other, and the orientation of the lower label 110 and the upper label 120 may be different from the orientation of the first and second ribs. Figure 29A and 29B For example, Figure 29C As shown in , a first point A5 on the edge E of the lower label 110 and the upper label 120 can be set to be adjacent to a first rib providing a tangent line L5, and a second point A6 on the edge E of the lower label 110 and the upper label 120 can be set to be adjacent to a second rib providing a tangent line L6 intersecting the tangent line L5. In this way, the two points on the edge E of the lower label 110 and the upper label 120 can be positioned relative to the first rib and the second rib. Figures 29A to 29C The modifications shown in can be applied to the base plates 2 , 220 , 320 , 420 , and 520 , the first ribs 25 , and the second ribs 26 in the first to fifth embodiments.

[0166] In the first embodiment, four magnets 271 to 274 are provided on the upper surface 21 of the base plate 2. However, the number of magnets need not be four and can be arbitrarily varied. Furthermore, the number of magnetic bodies 381 to 384 provided on the lower surface 35 of the pressure plate 3 can also be arbitrarily varied. Furthermore, the magnetic bodies 381 to 384 on the pressure plate 3 can be magnets. In the latter case, the magnets 271 to 274 provided on the base plate 2 can be magnetic bodies.

[0167] In the first to fifth embodiments, the peeling sheet of the upper label 12 has a cutting line P extending in its longitudinal direction and passing through the center in its width direction. However, the position of the cutting line P is not restrictive. For example, the cutting line P may extend in a direction perpendicular to the longitudinal direction of the peeling sheet. Alternatively, as FIG. 30A to FIG. 30B As shown in , the release sheet may be a transparent sheet on which a pattern is printed. FIG. 30A to FIG. 30B In the example of FIG, due to the transparency of the peeling sheet, it is possible to facilitate position adjustment between the upper label 712 and the lower label 711 to create the stacked label 710, and the user is less likely to forget to peel off the peeling sheet because the peeling sheet can be easily visually identified due to the pattern (text “label”) on the transparent peeling sheet. In addition, even if Figure 30C As shown in FIG, the upper label 712 is incorrectly set on the lower label 711 placed on the jig 10 , and due to the incorrect orientation of the pattern on the upper label 712 , the user can also easily recognize the incorrect arrangement of the upper label 712 .

[0168] Furthermore, in the first embodiment, the pressure plate 3 may have a thin plate-like shape. In the latter case, while the lower label 11 and the upper label 12 are sandwiched between the base plate 2 and the pressure plate 3, only the upper label 12 may be folded upward along the front edge of the pressure plate 3. By this folding, the peeling sheet can be quickly separated at the cutting line P. At this time, the cutting edge portions 121, 122 (see FIG. 1 ) are cut. Figure 11B ) is lifted from the adhesive sheet, thereby facilitating removal of the release sheet from the adhesive sheet.

[0169] While the embodiments have been described in detail with reference to the embodiments thereof, it will be apparent to those skilled in the art that many modifications and variations therein may be made.
