Description

  The present invention relates to a roll tape used in a tape printer and a tape unit using the roll tape, and more specifically, a long tape wound around a core in a roll shape is prevented from being scattered during storage. The present invention relates to a rolled tape and a tape unit using the same.

  2. Description of the Related Art Various types of tape printing apparatuses that print characters and the like on a roll tape, which is a long sheet in which a release sheet is bonded to an adhesive sheet, have been proposed. Usually, this roll tape is wound around a cylindrical core and mounted as a tape unit which is a cartridge for attaching to and detaching from a tape printer. In the tape printer, the roll core of the tape unit is rotatably attached to the roll tape holder, and the roll tape is pulled out from the roll tape holder that is detachably supported by the tape printer.

  By the way, if the tape unit is stored without stopping the tip of the roll tape wound around the winding core with a stop tape or the like, the roll tape depends on the difference between the curvature of the outer release paper and the curvature of the inner adhesive sheet. Stress was generated inside, and the roll tape was sometimes scattered by this internal stress. As a result, problems such as wrinkles and slack in the roll tape in the tape unit, and the winding core falling off from the roll tape have occurred.

Therefore, conventionally, a tape unit that can prevent the roll tape from being scattered has been proposed. For example, by attaching a substantially flat sliding member slidable in the axial direction of the core to the end surface of the roll tape wound around the core with an adhesive sheet or the like, There is known a tape unit that can hold a side end face of a roll tape while being wound while absorbing a dimensional change in the tape width direction and prevent the roll tape from being scattered (for example, Patent Document 1). reference).

  Next, details of each embodiment of the tape unit 100, which is the main part of the present invention, will be described with reference to the drawings.

  (First Embodiment) First, a tape unit 200 will be described as a first embodiment of the tape unit 100. FIG. FIG. 16 is an external perspective view of the tape unit 200. FIG. 17 is a plan view showing a state in which the leading end side of the roll tape 210 is developed. FIG. 18 is a rear view of the state in which the leading end side of the roll tape 210 is developed. FIG. 19 is a cross-sectional view in the direction of the arrow along line AA in a state where the leading end side of the roll tape 210 is developed. FIG. 20 is an external perspective view of the winding core 220. Of the roll tape 210, one end wound around the core 220 is the rear end side of the roll tape 210, and the other end inserted into the insertion port 18 is the front end side of the roll tape 210. Further, the upward direction in FIGS. 17 and 18 and the right direction in FIG. 19 correspond to the leading end side of the roll tape 210.

  As shown in FIG. 16, the tape unit 200 according to this embodiment is a tape cartridge configured by tightly winding a roll tape 210 around a core 220. The tape unit 200 does not use a conventional stopper tape for preventing scatter when stored, but has the configuration described in detail below, so that the roll tape 210 can be scattered even when stored for a long time. There is no. When the tape unit 200 is used in the tape printer 1, the tape unit 200 is attached to the roll tape holder 3 as described above, and the leading end side of the roll tape 210 is pulled out and attached to the roll tape holder storage portion 4. That's fine. In this tape unit 200, the rear end side of the roll tape 210 is wound without being bonded and fixed to the core 220 so that the roll tape 210 can be used up to the end. Further, FIG. 16 shows the tape unit 200 in a state where the front end side of the roll tape 210 is slightly pulled out.

  As shown in FIGS. 17 and 19, in the roll tape 210 according to this embodiment, a recording medium 211 (corresponding to a printing medium) made of thermal paper is continuously provided on the surface of the roll tape 210 in a tape shape. An adhesive layer 217 is provided on the back surface of 211, and a release paper 212 (corresponding to a release layer) is detachably attached to the adhesive layer 217. As an example of the pressure-sensitive adhesive layer 217, an acrylic emulsion-type pressure-sensitive adhesive can be used. Therefore, the roll tape 210 has a three-layer structure. The roll tape 210 is wound in a roll shape with the release paper 212 on the outside and the recording medium 211 on the inside, and the same applies to the other embodiments described below.

  In the roll tape 210, a plurality of identical circular cuts are made at equal intervals on the recording medium 211 so that each circular label 211A can be peeled off. The roll tape 210 is cut by the cutter unit 8 in the tape width direction at the cutting portion 219 located approximately in the middle between the adjacent circular labels 211A so that one label piece is created. ing. That is, the roll tape 210 according to the present embodiment is subjected to die cutting processing in which a plurality of label pieces previously formed in a label shape are continuously arranged at a constant interval. Note that the roll tape 210 of this embodiment has a tape width of 32 mm, and each circular label 211A has a diameter of 12 mm.

  Further, as shown in FIGS. 18 and 19, a sensor mark 215, which is painted black in a rectangular shape, is provided on the back surface of the release paper 212 on one end side in the tape width direction of the roll tape 210 (left side in FIG. 18). Printing is continuously performed at regular intervals in the longitudinal direction of the roll tape 210 at a distance. As an example, the sensor mark 215 is a rectangle having a long side of 13 mm and a short side of 5 mm, and each sensor mark 215 is printed at a pitch of 12 mm. This sensor mark 215 is printed approximately in the middle of each adjacent circular label 211A so as to be equidistant from each adjacent circular label 211A. Further, characters (not shown) which are identification information apart from the sensor mark 215 are also printed.

  Furthermore, in the roll tape 210 of the present embodiment, the slit portions 218 cut into a U-shape that opens toward the tape front end direction (that is, the downstream side in the tape transport direction) in the release paper 212 are adjacent to each other. A plurality of circular labels 211A are continuously formed between each of them. The slit portion 218 communicates with a cut portion 218a in which the release paper 212 is cut in parallel with the tape width direction and both ends of the cut portion 218a, and the release paper 212 is cut in parallel with the tape longitudinal direction. It is comprised by the cut | notch parts 218b and 218c.

  In the roll tape 210 wound around the winding core 220, external moisture can enter both the release paper 212 and the pressure-sensitive adhesive layer 217 through the slit portion 218 (the cut portions 218 a to 218 c). That is, the cut portions 218a to 218c function as moisture absorption slits for the roll tape 210 (particularly, the release paper 212 and the adhesive layer 217) to promote moisture absorption. Further, the cut portion 218a formed in the tape width direction functions as a slit for reducing elasticity that reduces the elasticity of the roll tape 210 (particularly, the release paper 212). In this embodiment, the cut portion 218a is 10 mm, and the cut portions 218b and 218c are 8 mm each. Further, in order to allow the adhesive layer 217 to absorb moisture, the slit portion 218 has a depth of cut that is at least enough to reach the pressure-sensitive adhesive layer 217.

  Here, in this embodiment, the slit portion 218 is formed as a U-shaped slit including the cut portions 218a to 218c, so that the slit portion 218 is configured as an integrated slit that functions as a moisture absorption slit and an elastic reduction slit. ing. Further, by opening the U-shaped slit portion 218 toward the downstream side in the tape transport direction, various members (for example, guides) of the tape printer 1 can be used even when the roll tape 210 is pulled out and transported during tape printing. This prevents a problem that the slits 218 are caught on the members 97 and 98) and the release paper 212 is peeled off.

  As shown in FIG. 20, the core 220 according to the present embodiment includes a cylindrical body 221 in which a through-hole into which the holder shaft member 40 is inserted and an outer peripheral surface (cylindrical body) of the cylindrical body 221. 221 cylindrical side surfaces) and a plurality of rail-shaped protrusions 222 protruding in the entire circumferential direction. In the present embodiment, the five rail-shaped protrusions 222 are formed on the outer peripheral surface of the cylindrical body 221 so as to be parallel to the tape longitudinal direction of the roll tape 210 wound around the cylindrical body 221 at substantially equal intervals. Each is formed. The innermost surface of the roll tape 210 wound around the winding core 220 is fixed and supported on the upper end surfaces of the five rail-shaped protrusions 222. That is, since the roll tape 210 wound around the winding core 220 does not come into contact with the cylindrical body 221, the innermost surface of the roll tape 210 has a gap formed between the cylindrical body 221 and the opening 223. Can contact external moisture. Therefore, the roll tape 210 (particularly, the recording medium 211) can absorb moisture from the inner surface side through the opening 223. That is, the winding core 220 promotes moisture absorption from the inner surface side of the roll tape 210.

  By the way, in this embodiment, since the roll tape 210 before being wound around the core 220 is not bent, there is no difference in curvature between the release paper 212 and the recording medium 211 in the roll tape 210 before winding. . On the other hand, in the tape unit 200 in which the roll tape 210 is tightly wound around the winding core 220, the curvature of the inner recording medium 211 is larger than the curvature of the outer release paper 212. Therefore, stress is generated in the roll tape 210 due to the difference in curvature between the release paper 212 and the recording medium 211.

  However, the roll tape 210 wound around the core 220 can absorb moisture from the slit portion 218 (the cut portions 218a to 218c) which is a moisture absorption slit, so that the release paper 212 is easily bent and extended, and an adhesive. The layer 217 is easy to flow and deform in the gap between the release paper 212 and the recording medium 211. Furthermore, the elasticity of the release paper 212 is reduced by the slit portion 218 (the cut portion 218a) which is a slit for lowering elasticity, so that the release paper 212 is more easily bent and extended. On the other hand, the innermost surface of the roll tape 210 wound around the winding core 220 can absorb moisture from the opening 223, so that the recording medium 211 fixed to the winding core 220 is easily bent and extended.

  In the tape unit 200 having such a configuration, when the roll tape 210 is wound around the core 220, the release paper 212 positioned on the outer side is bent while extending in the tape longitudinal direction, while the recording medium 211 positioned on the inner side is peeled off. It bends with a larger curvature than paper 212. Further, the adhesive layer 217 is fluidly deformed according to the internal stress of the roll tape 210 so as to buffer the difference in curvature between the release paper 212 and the recording medium 211. As the time elapses, the roll tape 210 gradually adapts to the shape wound around the core 220, and the shape of the roll tape 210 is stabilized while being wound around the core 220. . Therefore, even if the tape unit 200 does not use a stop tape after its manufacture, the roll tape 210 does not come apart during storage.

  As described above, according to the tape unit 200 according to the present embodiment, the slit portion 218 is formed on the release paper 212 in the roll tape 210 that is composed of the recording medium 211, the adhesive layer 217, and the release paper 212 and is wound around the winding core 220. Formed. Therefore, at least the adhesive layer 217 can absorb moisture by the slit portion 218 (the cut portions 218a to 218c) which is a moisture absorption slit, and the roll tape 210 is bent according to the internal stress and the shape is stabilized. Furthermore, since the elasticity of the release paper 212 is reduced by the slit portion 218 (the cut portion 218a) which is a slit for lowering elasticity, it is easy to bend according to the internal stress of the roll tape 210. Therefore, it is possible to easily and effectively prevent the roll tape 210 from being scattered when the tape unit 200 is stored, and to improve user convenience.

  In addition, the slit portion 218 is an integrated slit in which a moisture absorption slit and an elasticity reducing slit communicate with each other, forming a U-shape that opens toward the downstream side in the conveyance direction of the roll tape 210. Therefore, it is possible to more effectively prevent the roll tape 210 from being scattered with a simple configuration in which a U-shaped integrated slit is formed.

  Further, in the core 220 around which the roll tape 210 is wound, by providing a plurality of protrusions 222 on the cylindrical side surface of the cylindrical body 221, an opening 223 for allowing moisture absorption on the innermost surface of the roll tape 210 is provided. Formed. Therefore, in the roll tape 210 wound around the core 220, moisture can be absorbed from the opening 223 even on the innermost surface having a high curvature, so that the roll tape 210 can be more effectively prevented from being scattered.

  (Second Embodiment) Next, a tape unit 300 will be described as a second embodiment of the tape unit 100. FIG. FIG. 21 is an external perspective view of the tape unit 300. FIG. 22 is a plan view showing a state in which the leading end side of the roll tape 310 is developed. FIG. 23 is a rear view of the state in which the leading end side of the roll tape 310 is developed. FIG. 24 is a cross-sectional view in the direction of the arrows along line BB in a state where the leading end side of the roll tape 310 is developed. FIG. 25 is an external perspective view of the core 320. Of the roll tape 310, one end wound around the core 320 is the rear end side of the roll tape 310, and the other end inserted into the insertion port 18 is the front end side of the roll tape 310. Further, the upward direction in FIGS. 22 and 23 and the right direction in FIG. 24 correspond to the leading end side of the roll tape 310.

  As shown in FIG. 21, the tape unit 300 according to the present embodiment has the same basic configuration as the tape unit 200 of the first embodiment, and the roll tape 310 is tightly wound around the winding core 320. The tape cartridge is configured as described above. The tape unit 300 is also wound without being bonded and fixed to the core 320 so that the roll tape 310 can be used up to the end. FIG. 21 shows the tape unit 300 in a state in which the front end side of the roll tape 310 is slightly pulled out. Below, it demonstrates centering on a different point from the tape unit 200 of 1st Example.

  22 and 24, the roll tape 310 according to the present embodiment has a three-layer structure of a recording medium 311, an adhesive layer 317, and a release paper 312 as in the roll tape 210 of the first embodiment. It has become. On the other hand, the roll tape 310 is a normal tape that has not been die-cut, and can be cut at an arbitrary position to create a label piece of an arbitrary size.

  Further, as shown in FIG. 23 and FIG. 24, sensor marks 315 that are painted black in a rectangular shape are separated from the back surface of the release paper 312 by a predetermined interval at both end edges in the tape width direction of the roll tape 310. 310 is continuously printed at regular intervals in the longitudinal direction. As an example, the sensor mark 315 is a rectangle having a long side of 5 mm and a short side of 1 mm, and each sensor mark 315 is printed at a pitch of 2 mm.

  Further, in the roll tape 310 of the present embodiment, the slit portions 318 cut into a T-shape with the tape leading direction (that is, the downstream side in the tape transport direction) downward in the release paper 312 are formed at predetermined intervals. A plurality are formed continuously. The slit portion 318 communicates with a cut portion 318a in which the release paper 312 is cut in parallel to the tape width direction and a central portion of the cut portion 318a, and the release paper 312 is cut in parallel with the tape longitudinal direction. It is comprised by the notch part 318b.

  In the roll tape 310 wound around the winding core 220, external moisture can enter both the release paper 312 and the adhesive layer 317 through the slit portions 318 (cut portions 318 a and 318 b). That is, the notches 318a and 318b function as moisture absorption slits for the roll tape 310 (particularly, the release paper 312 and the adhesive layer 317) to promote moisture absorption. Further, the cut portion 318a formed in the tape width direction functions as a slit for reducing elasticity that reduces the elasticity of the roll tape 310 (particularly, the release paper 312). In this embodiment, the cut portion 318a is 10 mm, and the cut portion 318b is 8 mm. In order to allow the pressure-sensitive adhesive layer 317 to absorb moisture, the slit portion 318 has a cut depth that at least cuts the pressure-sensitive adhesive layer 317.

  Here, in this embodiment, the slit portion 318 is formed as a T-shaped slit including the cut portions 318a and 318b, so that the slit portion 318 is configured as an integrated slit that functions as a moisture absorption slit and an elastic reduction slit. ing. Further, by setting the T-shaped slit portion 318 downward on the downstream side in the tape conveyance direction, various members (for example, guides) of the tape printer 1 can be used even when the roll tape 310 is pulled out and conveyed during tape printing. This prevents a problem that the slits 318 are caught on the members 97 and 98) and the release paper 312 is peeled off.

  Further, as shown in FIG. 25, the core 320 according to the present embodiment includes a cylindrical body 321 in which a through hole into which the holder shaft member 40 is inserted is formed, and an outer peripheral surface (cylindrical body) of the cylindrical body 321. 321 cylindrical side surface) and a plurality of rail-like protrusions 322 protruding in parallel with the axial direction. In the present embodiment, the four rail-shaped protrusions 322 are formed on the outer peripheral surface of the cylindrical body 321 so as to be parallel to the tape width direction of the roll tape 310 wound around the cylindrical body 321 at substantially equal intervals. Each is formed. The innermost surface of the roll tape 310 wound around the core 320 is fixed and supported on the upper end surfaces of the four rail-shaped protrusions 322. That is, since the roll tape 310 wound around the winding core 320 does not come into contact with the cylindrical body 321, the innermost surface of the roll tape 310 has an opening 323 that is a gap formed between the cylindrical body 321. Can contact external moisture. Therefore, the roll tape 310 (particularly the recording medium 311) can absorb moisture from the inner surface side through the opening 323. That is, the winding core 320 promotes moisture absorption from the inner surface side of the roll tape 310.

  By the way, in this embodiment, since the roll tape 310 before being wound around the core 320 is not bent, there is no difference in curvature between the release paper 312 and the recording medium 311 in the roll tape 310 before being wound. . On the other hand, in the tape unit 300 in which the roll tape 310 is tightly wound around the core 320, the curvature of the inner recording medium 311 is larger than the curvature of the outer release paper 312. Therefore, stress is generated in the roll tape 310 due to the difference in curvature between the release paper 312 and the recording medium 311.

  However, the roll tape 310 wound around the winding core 320 can absorb moisture from the slit portions 318 (notches 318a and 318b) that are moisture absorption slits, so that the release paper 312 is easily bent and extended, and an adhesive. The layer 317 is easy to flow and deform in the gap between the release paper 312 and the recording medium 311. Furthermore, since the elasticity of the release paper 312 is reduced by the slit portion 318 (cut portion 318a) that is a slit for lowering elasticity, the release paper 312 is more easily bent and extended. On the other hand, the innermost surface of the roll tape 310 wound around the core 320 can absorb moisture from the opening 323, so that the recording medium 311 fixed to the core 320 is easily bent and extended.

  In the tape unit 300 having such a configuration, when the roll tape 310 is wound around the core 320, the release paper 312 positioned on the outer side is bent while extending in the tape longitudinal direction, while the recording medium 311 positioned on the inner side is peeled off. Bends with a larger curvature than paper 312. Further, the adhesive layer 317 is fluidly deformed according to the internal stress of the roll tape 310 so as to buffer the difference in curvature between the release paper 312 and the recording medium 311. As the time elapses, the roll tape 310 gradually adapts to the shape wound around the core 320, and the shape of the roll tape 310 is stabilized while being wound around the core 320. . Therefore, even if the tape unit 300 does not use a stop tape after its manufacture, the roll tape 310 does not come apart during storage.

  As described above, according to the tape unit 300 according to the present embodiment, the slit portion 318 is formed on the roll tape 310 including the recording medium 311, the adhesive layer 317, and the release paper 312 and wound around the core 320. 312 formed. Therefore, at least the pressure-sensitive adhesive layer 317 can absorb moisture by the slit portions 318 (notches 318a and 318b) which are moisture absorption slits, and the roll tape 310 is bent according to the internal stress and the shape is stabilized. Furthermore, the elasticity of the release paper 312 is reduced by the slit portion 318 (the cut portion 318 a) that is a slit for lowering elasticity, so that it is easily bent according to the internal stress of the roll tape 310. Therefore, it is possible to easily and effectively prevent the roll tape 310 from being scattered when the tape unit 300 is stored, thereby improving user convenience.

  In addition, the slit portion 318 is an integrated slit in which a moisture absorption slit and an elastic reduction slit communicate with each other and form a T shape with the downstream in the transport direction of the roll tape 310 as a downward direction. Therefore, it is possible to more effectively prevent the roll tape 310 from being scattered with a simple configuration in which a T-shaped integrated slit is formed.

  Further, in the core 320 around which the roll tape 310 is wound, by providing a plurality of protrusions 322 on the cylindrical side surface of the cylindrical body 321, an opening 323 for allowing moisture absorption on the innermost surface of the roll tape 310 is provided. Formed. Therefore, in the roll tape 310 wound around the core 320, moisture can be absorbed from the opening 323 even on the innermost surface having a high curvature, so that the roll tape 310 can be more effectively prevented from being scattered.

  In addition, this invention is not limited to the said embodiment, Of course, various improvement and deformation | transformation are possible within the range which does not deviate from the summary of this invention. For example, the “roll tape” of the present invention is not limited to the above-described embodiment, and the present invention can be applied to roll tapes of various shapes. For example, in the first embodiment, a tape for creating a label piece from which a circular label is peeled has been illustrated, but it can be any shape such as a label shape, a rectangular shape, a star shape, etc. The size, the formation position, and the like can be arbitrary.

  Further, in the roll tapes 210 and 310 according to the above-described embodiments, the integrated slits (slit portions 218 and 318) that serve as both the “moisture absorption slit” and the “elasticity reduction slit” are formed. ”And“ elasticity-reducing slit ”may be formed separately. Further, the position, quantity, shape, size, and the like of the “moisture absorption slit” and the “elasticity reduction slit” may be arbitrary.

  Furthermore, in the cores 220 and 320 according to the above-described embodiments, the projecting portions 222 and 322 are provided on the cylindrical bodies 221 and 321 to form the openings 223 and 323, respectively. However, if it is possible to effectively absorb moisture on the innermost surface of the roll tape, an “opening” may be formed in the “core” by another configuration. For example, in the “winding core”, a plurality of hole portions penetrating the cylindrical side surface may be formed, and this may be an “opening portion” that can absorb moisture on the innermost surface of the roll tape. Further, the positions, sizes, shapes, and the like of the protrusions 222 and 322 can be arbitrarily set. For example, a plurality of protrusions protruding in a bar shape may be formed.

  The roll tape of the present invention and a tape unit using the roll tape are obtained by rolling a long tape on which characters, symbols, images, etc. are printed on the surface by a printing means of a tape printing apparatus, and using the roll tape. It can be used for tape units.
