Description

  The present invention relates to an ink ribbon cassette including an ink ribbon having a base material layer and an ink layer, a delivery unit for feeding out the ink ribbon, and a winding unit for winding up the ink ribbon.

  2. Description of the Related Art Printing devices that use ink ribbons to print images such as characters on printed materials such as cards are widely used. The ink ribbon includes a ribbon (base material layer) extending in a strip shape and an ink layer formed on the ribbon and containing a dye or the like. In printing using an ink ribbon, ink is transferred to the receiver in a pattern corresponding to the desired image to be printed. In this case, in the ink ribbon that has been subjected to ink transfer, a portion where ink has been removed due to transfer to the image receiving member is present in a pattern corresponding to the printed image. For this reason, it is possible to specify the printed image from the ink ribbon after the ink transfer. Therefore, when information to be concealed such as ID information is printed on an object to be printed using an ink ribbon, care must be taken in handling the ink ribbon that has been subjected to ink transfer.

  In order to cope with such a problem, for example, in Patent Document 1, an ink ribbon in which a heat-sensitive adhesive is applied to a portion of the base material layer where the ink layer is not formed is provided, and the ink ribbon after the ink transfer is heated. An ink ribbon cassette provided with a heating roller is proposed. In the ink ribbon cassette described in Patent Document 1, before the ink ribbon after ink transfer is taken up by the take-up unit, the heat-sensitive adhesive is heated by a heating roller, and thereby the heat-sensitive adhesive is activated. . For this reason, when the ink ribbon to which ink has been transferred is wound up by the winding unit, the newly wound up ink ribbon is bonded to the already wound inner ink ribbon by the heat-sensitive adhesive. Thereby, a wound body of the ink ribbon solidified by the heat-sensitive adhesive is formed. In the ink ribbon cassette described in Patent Document 1, the ink missing portion of the ink ribbon after the ink transfer is thus prevented from being visually recognized from the outside.

JP 7-156489 A

  In the ink ribbon cassette described in Patent Document 1, a heat-sensitive adhesive is applied to a portion of the ink ribbon base layer where the ink layer is not formed. For this reason, when the wound body of the ink ribbon is cut in the radial direction, and the portion to which the heat-sensitive adhesive is applied is removed, it is considered that the ink missing portion of the ink layer can be taken out from the wound body. . In this case, the ink missing portion of the ink layer remains in a pattern corresponding to the printed image, and therefore, it is considered that the printed image is specified from the ink missing portion of the ink ribbon.

  An object of the present invention is to provide an ink ribbon cassette that can effectively solve such problems.

The ink ribbon cassette is characterized in that the adhesive layer has the same color as the ink layer of the ink ribbon and has a predetermined geometric pattern.

  In the second ink ribbon cassette according to the present invention, the adhesive layer of the tape may be provided with a plurality of openings arranged in a predetermined pattern.

  A third ink ribbon cassette according to the present invention includes an ink ribbon having a base material layer and an ink layer, a delivery unit for feeding out the ink ribbon, a winding unit for winding up the ink ribbon, and a vicinity of the winding unit. And a tape supply unit that supplies a tape to be bonded to the ink layer side of the ink ribbon, and the tape has a tape base and adhesive layers provided on both sides of the tape base. In the ink ribbon cassette, the adhesive layer on the side of the adhesive layer that contacts the ink layer of the ink ribbon has a predetermined geometric pattern.

  In the third ink ribbon cassette according to the present invention, a plurality of openings arranged in a predetermined pattern may be provided in the adhesive layer on the side of the adhesive layer that contacts the ink layer of the ink ribbon.

  A fourth ink ribbon cassette according to the present invention includes an ink ribbon having a base material layer and an ink layer, a delivery unit for feeding out the ink ribbon, a winding unit for winding up the ink ribbon, and a vicinity of the winding unit. And a tape supply unit that supplies a tape to be bonded to the ink layer side of the ink ribbon, and the tape is on the side of the tape base material that contacts the ink layer of the ink ribbon. An ink ribbon cassette, wherein the tape base material includes a light shielding layer that shields light, and the adhesive layer has the same color as the ink layer of the ink ribbon. is there.

  In the first to fourth ink ribbon cassettes according to the present invention, preferably, the adhesion force between the ink layer of the ink ribbon and the tape is greater than the adhesion force between the ink layer of the ink ribbon and the base material layer. The adhesive layer of the tape is configured so as to be larger.

  According to the first ink ribbon cassette of the present invention, the tape bonded to the ink layer side of the ink ribbon includes a tape base material and an adhesive provided on the side of the tape base material that contacts the ink layer of the ink ribbon. And have a layer. Among these, the tape base material has the same color as the ink layer of the ink ribbon and has a predetermined geometric pattern, and the adhesive layer is formed of a transparent adhesive material. For this reason, when the ink ribbon after ink transfer is observed, the region of the ink layer where the ink is missing overlaps with the tape base material of the tape as the region having the same color as the ink remaining portion of the ink layer. The For this reason, it is impossible to distinguish an area where the tape base material of the tape overlaps the ink missing part of the ink layer and the ink remaining part of the ink layer. This can prevent the printed image from being identified from the ink missing portion of the ink ribbon.

  According to the second ink ribbon cassette of the present invention, the tape bonded to the ink layer side of the ink ribbon includes a tape base material and an adhesive provided on the side of the tape base material that contacts the ink layer of the ink ribbon.

For this reason, when the ink ribbon after the ink transfer is observed, an area of the ink layer that overlaps with the adhesive layer of the tape is visually recognized as an area having the same color as the ink remaining part of the ink layer. . For this reason, it is impossible to distinguish an area where the ink layer of the ink layer overlaps the adhesive layer of the tape and an ink remaining part of the ink layer. This can prevent the printed image from being identified from the ink missing portion of the ink ribbon.

  According to the third ink ribbon cassette of the present invention, the tape bonded to the ink layer side of the ink ribbon has a tape base material and adhesive layers provided on both sides of the tape base material. For this reason, when the ink ribbon to which ink has been transferred is taken up by the take-up unit, the newly-taken ink ribbon is already taken up by the adhesive layers provided on both sides of the tape base material. Bonded to the ribbon. As a result, a wound body of the ink ribbon solidified by the adhesive layer of the tape is formed. According to the invention, the adhesive layer on the side in contact with the ink layer of the ink ribbon in the adhesive layer of the tape has a predetermined geometric pattern. For this reason, even when the wound body of the ink ribbon solidified by the tape is disassembled, the pattern of the ink missing portion of the ink layer is destroyed according to the geometric pattern of the adhesive layer along with the disassembly. The This can prevent the printed image from being identified from the ink missing portion of the ink ribbon.

  According to the fourth ink ribbon cassette of the present invention, the tape bonded to the ink layer side of the ink ribbon includes a tape base material and an adhesive provided on the side of the tape base material that contacts the ink layer of the ink ribbon. And have a layer. Among these, the tape base material includes a light shielding layer that shields light, and the adhesive layer has the same color as the ink layer of the ink ribbon.

First Embodiment Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. First, the entire ink ribbon cassette 20 will be described with reference to FIG.

Ink Ribbon Cassette As shown in FIG. 1, an ink ribbon cassette 20 used by being incorporated in a predetermined printing device (not shown) is an ink ribbon configured corresponding to the type of the printing device to be incorporated, such as a tape-like ink. A ribbon 30, a delivery unit 23 that sends out the ink ribbon 30 in the direction indicated by the arrow R ₁ , a winding unit 24 that winds the ink ribbon 30 in the direction indicated by the arrow R ₂ , and the sending unit 23 and the winding unit 24. Guide rolls 25 a and 25 b that are provided therebetween and demarcate the delivery path of the ink ribbon 30. As will be described later, the ink ribbon 30 has a base material layer and an ink layer formed by applying ink on the base material layer.
As shown in FIG. 1, the ink ribbon 30 is guided by the guide rolls 25a and 25b and passes through the printing unit 12 of the printing apparatus.

  As shown in FIG. 1, the printing unit 12 of the printing apparatus includes a print head 13 and a platen roll 14 that is provided to face the print head 13 with the card 15 interposed therebetween and supports the card 15. . Of these, the print head 13 is a so-called thermal transfer type print head. The ink in the ink layer of the ink ribbon 30 is heated by the print head 13 in a predetermined pattern corresponding to the ID information, and thereby the ink melted in the predetermined pattern corresponding to the ID information is transferred onto the card 15. . In this way, ID information is printed on the card 15, and an ink missing portion corresponding to the ID information is formed in the ink layer of the ink ribbon 30.

  The ink ribbon 30 in which the ink missing portion corresponding to the ID information is formed is wound up by the winding unit 24. Here, as illustrated in FIG. 1, the ink ribbon cassette 20 further includes a tape supply unit 41 that is provided in the vicinity of the winding unit 24 and supplies a tape 42 that is bonded to the ink ribbon 30. Hereinafter, the ink ribbon 30 and the tape 42 will be described in detail with reference to FIGS.

  FIG. 2A is an enlarged view showing the vicinity of the winding portion 24 of the ink cassette 20 shown in FIG. 1, and FIG. 2B is a diagram in which the tape 42 is bonded to the ink ribbon 30 in the winding portion 24. FIG. As shown in FIG. 2A, when the tape 42 is bonded to the ink ribbon 30, the ink ribbon 30 and the tape 42 are curved along the roll surface of the winding unit 24. However, in FIG. 2B and the drawings after FIG. 2B, for convenience, the ink ribbon 30 and the tape 42 are drawn ignoring the curved state.

  As shown in FIGS. 2 (a) and 2 (b), the ink ribbon 30 that has been subjected to ink transfer includes a base material layer 35 and an ink layer 36. 2B, the ink layer 36 includes an ink remaining portion 36a made of ink remaining without being transferred to the card 15, and an ink drop corresponding to the ID information printed on the card 15. It consists of the part 36b. In this case, for example, a character “AZ” is printed on the card 15 as the ID information. Therefore, as shown in FIG. 2B, the ink missing portion 36b has a pattern corresponding to “AZ”. Yes.

As shown in FIG. 2A, the tape 42 supplied from the tape supply unit 41 is wound around the winding unit 24 together with the ink ribbon 30 that has undergone ink transfer. Therefore, as shown in FIG. 2 (a), the winding section 24 when rotated in the R ₂ direction, the ink layer 36 side of the ink ribbon 30, the tape 42 from the tape supply portion 41 is bonded. At this time, the tape 42 is preferably bonded to the ink ribbon 30 so that the tape 42 is symmetric with respect to the center line 31 of the ink ribbon 30 (see FIG. 2B).
2A and 2B and FIG. 2A and FIG. 2B and subsequent drawings, of the surfaces on both sides of the tape 42, the surface bonded to the ink layer 36 of the ink ribbon 30 to which ink has been transferred. Is represented by reference numeral 42a, and the surface opposite to the surface 42a is represented by reference numeral 42b.

As shown in FIG. 2B, the width L _{2 of the} tape 42 is determined to be substantially the same as the width L ₁ of the ink ribbon 30. However, it is not limited thereto, the width L ₂ of the tape 42 has only to have a width enough to be able to cover the ink omission portion 36b of the ink layer 36 of at least the ink ribbon 30. As a result, the ID information printed on the card 15 can be prevented from being specified from the ink missing portion 36b of the ink layer 36, as will be described later.

  Next, the structure of the tape 42 will be described in detail with reference to FIGS. FIG. 3A is a cross-sectional view showing the tape 42, and FIG. 3B is a perspective view showing the tape 42. As shown in FIG. 3A, the tape 42 includes a tape base material 52 and an adhesive layer 53 provided on the side of the tape base material 52 that contacts the ink layer 36 of the ink ribbon 30. Among these, as shown in FIGS. 3 (a) and 3 (b), the tape base material 52 is composed of a base material portion 52a and a plurality of openings 52b arranged in a predetermined pattern between the base material portions 52a. For this reason, the tape base material 52 has a predetermined geometric pattern. The opening 52b of the tape base material 52 is formed, for example, by punching the base material portion 52a with a mold having a predetermined shape.

In the present embodiment, as shown in FIG. 2A, the ink ribbon 30 that has undergone ink transfer is wound around the winding unit 24 so that the ink layer 36 is positioned outside the base material layer 35. Therefore, the “adhesive layer provided on the side of the tape substrate that contacts the ink layer of the ink ribbon” refers to the both sides (outside and inside) of the tape substrate that is wound around the winding unit 24. It means that an adhesive layer is provided on the inner side (center side of the winding part 24).
Although not shown, it is also conceivable that the ink ribbon 30 that has been subjected to the ink transfer is wound around the winding unit 24 so that the ink layer 36 is positioned inside the base material layer 35. In this case, “the adhesive layer provided on the side of the tape substrate that contacts the ink layer of the ink ribbon” means that the adhesive layer is provided on the outer side of the tape substrate wound around the winding unit 24. Means.

  Further, the base material portion 52 a of the tape base material 52 has the same color as the ink remaining portion 36 a of the ink layer 36 of the ink ribbon 30. Here, “the base material portion 52 a of the tape base material 52 has the same color as the ink residual portion 36 a of the ink layer 36” means that the ink residue of the base material portion 52 a of the tape base material 52 and the ink layer 36 is retained. When the portions 36a are adjacent to each other without a gap and these are observed, the boundary line between the base material portion 52a of the tape base material 52 and the ink remaining portion 36a of the ink layer 36 is indistinguishable with the naked eye, This means that the color of the base material portion 52a is similar to the color of the ink remaining portion 36a.

  The adhesive layer 53 of the tape 42 is formed from a transparent adhesive material. Here, “transparent” means that the tape base material 52 of the tape 42 is directly visually recognized and the tape base material 52 of the tape 42 is visually recognized through the adhesive layer 53. It means that the colors are almost the same.

Next, the adhesion force realized by the adhesive layer 53 will be described. Preferably, the adhesive layer of the tape 42 is such that the adhesive force between the ink layer 36 of the ink ribbon 30 and the tape 42 is greater than the adhesive force between the ink layer 36 of the ink ribbon 30 and the substrate layer 35. 53 is configured. That is, an adhesive material for forming the adhesive layer 53 is selected so as to realize such adhesion.
Although not shown, release paper may be provided on the adhesive layer 53 of the tape 42 in order to prevent the tapes 42 wound around the tape supply unit 41 from being bonded to each other. Such release paper is removed by a release paper take-up shaft (not shown) before the tape 42 is wound around the take-up unit 24.

  Next, the operation of the present embodiment having such a configuration will be described. Here, first, ID information is printed on the card 15 using the ink ribbon 30, and then the operation of adhering the tape 42 to the ink ribbon 30 to which ink has been transferred will be described.

  First, the card 15 is prepared, and then the card 15 is conveyed toward the printing unit 12. On the other hand, in the ink ribbon cassette 20, as shown in FIG. 1, the ink ribbon 30 is fed from the sending unit 23 toward the winding unit 24 in a state where an appropriate tension is applied.

  When the card 15 reaches between the print head 13 of the printing unit 12 and the platen roll 14, the print head 13 presses the ink ribbon 30 against the card 15 while heating it with a predetermined pattern corresponding to the ID information. As a result, the ink on the ink ribbon 30 is transferred onto the card 15 in a predetermined pattern. As a result, the ID information is printed on the card 15 and the ink removal portion 36 b corresponding to the ID information is formed in the ink layer 36 of the ink ribbon 30.

  The ink ribbon 30 that has undergone ink transfer after passing through the printing unit 12 is wound up by the winding unit 24. On the other hand, the tape 42 supplied from the tape supply unit 41 is also taken up by the winding unit 24. Therefore, as shown in FIGS. 2A and 2B, the tape 42 from the tape supply unit 41 is bonded to the ink layer 36 side of the ink ribbon 30. Hereinafter, the ink ribbon 30 to which the tape 42 is bonded will be described with reference to FIGS. 4 (a), 4 (b), and 4 (c).

  FIG. 4A is a plan view showing the case where the ink ribbon 30 to which the tape 42 is bonded is viewed from the surface 42b side of the tape 42, and FIG. 4B is the tape 42 shown in FIG. FIG. 4 is a view showing a cross section taken along line IV-IV of the ink ribbon 30 to which is adhered. FIG. 4C is a cross-sectional view showing a state where the base material layer 35 is peeled from the ink ribbon 30 to which the tape 42 shown in FIG.

  As described above, the base material portion 52 a of the tape base material 52 has the same color as the ink remaining portion 36 a of the ink layer 36 of the ink ribbon 30. The adhesive layer 53 is formed from a transparent adhesive material. For this reason, when the ink ribbon 30 to which the ink has been transferred is observed, the region of the ink missing portion 36b of the ink layer 36 that overlaps the base material portion 52a of the tape base material 52 of the tape 42 (reference numeral in FIG. 4A). A region indicated by a dotted line in the region indicated by 36b) is visually recognized as a region having the same color as the ink remaining portion 36a of the ink layer 36. For this reason, it is not possible to distinguish the region of the ink missing portion 36b of the ink layer 36 that overlaps the base portion 52a of the tape base 52 and the ink remaining portion 36a of the ink layer 36.

  Therefore, the region that can be visually recognized from the outside of the ink missing portion 36b of the ink layer 36 is a region that overlaps with the opening 52b of the tape base material 52 (inside the solid line in the region indicated by reference numeral 36b in FIG. 4A). Area). As apparent from FIG. 4A, the entire ink missing portion 36b of the ink layer 36 is based only on the information regarding the region of the ink missing portion 36b of the ink layer 36 that overlaps the opening 52b of the tape base material 52. It is difficult to guess the shape. That is, according to the present embodiment, it is possible to prevent the entire shape of the ink missing portion 36b of the ink layer 36 from being visually recognized when the ink ribbon 30 to which ink has been transferred is observed from the outside. The identification of the ID information printed on the card 15 can be prevented.

  Next, consider the case where the tape 42 is peeled from the ink ribbon 30 that has been subjected to ink transfer. As described above, the adhesive force between the ink layer 36 of the ink ribbon 30 and the tape 42 is greater than the adhesive force between the ink layer 36 of the ink ribbon 30 and the base material layer 35. An adhesive layer 53 is configured. For this reason, as shown in FIG. 4C, when the tape 42 is peeled from the ink ribbon 30 after the ink transfer, the ink remaining portion 36a of the ink layer 36 remains on the tape 42 side.

  When light is transmitted through the tape 42 with the ink layer 36 shown in FIG. 4C, the light transmission patterns are classified into the following four types. That is, a pattern that transmits through the first region 55a composed of the base material portion 52a and the adhesive layer 53, a pattern that transmits through the second region 55b composed of the adhesive layer 53, the base material portion 52a, the adhesive layer 53, and the ink remaining portion 36a. There are four patterns: a pattern that transmits through the third region 55c, and a pattern that transmits through the fourth region 55d, which includes the adhesive layer 53 and the ink remaining portion 36a.

  When light is transmitted through the tape 42 with the ink layer 36 shown in FIG. 4C, the pattern of light passing through the ink missing portion 36b is the pattern that transmits the first region 55a among the above four patterns. There are two patterns that pass through the second region 55b. On the other hand, there are two patterns through which the light passes through the ink remaining portion 36a: the pattern that transmits through the third region 55c and the pattern that transmits through the fourth region 55d among the four patterns described above. As described above, according to the present embodiment, the pattern in which light passes through the ink missing portion 36b and the pattern in which light passes through the ink remaining portion 36a are classified into two types. For this reason, it is possible to prevent the shape of the ink missing portion 36b of the ink layer 36 from being recognized based on the transmitted light.

Comparison Mode Next, the effects of the first embodiment will be described in comparison with the comparison mode with reference to FIGS. FIGS. 5A to 5C are diagrams showing comparative forms, and correspond to FIGS. 4A to 4C in the first embodiment.

  4 (a) to 4 (c) is different only in that no opening is provided in the tape base material 52, and other configurations are the same as those in FIGS. 1 to 4 (a) to (a). This is substantially the same as the first embodiment shown in c). In the comparison form shown in FIGS. 5A to 5C, the same parts as those in the first embodiment shown in FIGS. Is omitted.

  As described above, in the comparative form, the tape base material 52 of the tape 100 is not provided with an opening. Therefore, all the tape base materials 52 consist of the base material part 52a. For this reason, as shown in FIG. 5B, all of the ink missing portions 36 b of the ink layer 36 overlap with the base material portion 52 a of the tape base material 52. For this reason, all of the ink missing part 36b is visually recognized as an area having the same color as the ink remaining part 36a. This prevents the shape of the ink missing portion 36b of the ink layer 36 from being visually recognized.

  Next, consider a case where the tape 100 is peeled from the ink ribbon 30 after ink transfer in the comparative embodiment.

  When light is transmitted through the tape 100 with the ink layer 36 shown in FIG. 5C, the light transmission patterns are classified into the following two types. On the other hand, a pattern that transmits through the first region 55a composed of the base material portion 52a and the adhesive layer 53, and a pattern that transmits through the third region 55c composed of the base material portion 52a, the adhesive layer 53, and the ink remaining portion 36a. There are two ways.

When light is transmitted through the tape 100 with the ink layer 36 shown in FIG. 5C, the light passes through only the first pattern 55a through the first region 55a. . On the other hand, the pattern through which the light passes through the ink remaining portion 36a is only one of the patterns that pass through the third region 55c.
As described above, the base material portion 52a has the same color as the ink remaining portion 36a, and the adhesive layer 53 is formed of a transparent adhesive material. For this reason, the color of the light transmitted through the first region 55a is the same as the color of the light transmitted through the third region 55c.
However, as is apparent from FIG. 5C, the first region 55a is thinner than the third region 55c by the ink remaining portion 36a. For this reason, the light transmittance in the first region 55a differs from the light transmittance in the third region 55c by the ink remaining portion 36a. For this reason, when the light transmitted through the first region 55a and the light transmitted through the third region 55c are compared, it is conceivable that a slight difference in density appears due to the difference in transmittance. Therefore, light transmitted through the first region 55a and light transmitted through the third region 55c can be distinguished.

  In the comparative form, as described above, the pattern in which light passes through the ink missing portion 36b is only one pattern that transmits through the first region 55a. For this reason, the shape of the ink missing portion 36b can be recognized based on the difference in density of the transmitted light. In the comparative form, it is conceivable that the ID information printed on the card 15 is specified from the ink ribbon 30 after the ink transfer in this way.

  On the other hand, according to the first embodiment of the present invention, as described above, when light is transmitted through the tape 42 with the ink layer 36, the pattern of light passing through the ink missing portion 36b is The pattern includes two patterns that pass through the first region 55a or the second region 55b. Also, there are two patterns of light passing through the ink remaining portion 36a, that is, patterns that transmit through the third region 55c or the fourth region 55d. For this reason, the shape of the ink missing portion 36b is not recognized due to the difference in light transmittance. As a result, it is possible to more firmly prevent the ID information printed on the card 15 from being specified from the ink ribbon 30 to which ink has been transferred.

Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 6A is a cross-sectional view showing a tape according to the second embodiment of the present invention, and FIG. 6B is a perspective view showing the tape according to the second embodiment of the present invention. FIG. 7A is a plan view showing an ink ribbon to which a tape is adhered in the second embodiment of the present invention, and FIG. 7B is a diagram in which the tape shown in FIG. 7A is adhered. It is sectional drawing along the VII-VII line of the ink ribbon. FIG. 8A is a cross-sectional view showing the tape peeled from the ink ribbon in the second embodiment of the present invention, and FIG. 8B is a cross-sectional view showing the ink ribbon peeled from the tape. FIG. 8C is a plan view showing the ink ribbon peeled from the tape.

  The second embodiment shown in FIGS. 6 to 8 is that the adhesive layer of the tape supplied from the tape supply unit has the same color as the ink layer of the ink ribbon and has a predetermined geometric pattern. The only difference is the other configuration, which is substantially the same as that of the first embodiment shown in FIGS. In the second embodiment shown in FIG. 6 to FIG. 8, the same parts as those in the first embodiment shown in FIG. 1 to FIG.

  First, the structure of the tape 42 in this embodiment will be described with reference to FIGS. As shown in FIG. 6A, the tape 42 includes a tape base material 62 and an adhesive layer 63 provided on the side of the tape base material 62 that contacts the ink layer 36 of the ink ribbon 30. Among them, the adhesive layer 63 is composed of an adhesive 63a and a plurality of openings 63b arranged in a predetermined pattern between the adhesives 63a, as shown in FIGS. 6 (a) and 6 (b). The adhesive layer 63 has a predetermined geometric pattern.

  Further, the adhesive 63 a of the adhesive layer 63 has the same color as the ink remaining portion 36 a of the ink layer 36 of the ink ribbon 30. Here, the “same color” means that the adhesive 63a and the remaining ink portion 36a are adjacent to each other without any gap as in the case of the base material portion 52a in the first embodiment, and the adhesion is observed when these are observed. This means that the color of the adhesive 63a and the color of the ink remaining portion 36a are similar to the extent that the boundary line between the agent 63a and the ink remaining portion 36a is indistinguishable with the naked eye.

  Further, as in the case of the first embodiment described above, the adhesion between the ink layer 36 of the ink ribbon 30 and the tape 42 is such that the adhesion between the ink layer 36 of the ink ribbon 30 and the base material layer 35. The adhesive 63a of the adhesive layer 63 of the tape 42 is configured to be greater than the force.

  The material for forming the tape base material 62 of the tape 42 is not particularly limited, and a well-known material used for holding an adhesive in a general tape is used. In the present embodiment, for example, a transparent material is used as a material for forming the tape base material 62.

  Next, the operation of the present embodiment having such a configuration will be described. The operation of printing the ID information on the card 15 using the ink ribbon 30 is the same as in the case of the first embodiment, and a description thereof will be omitted. Here, an operation by adhering the tape 42 to the ink ribbon 30 to which ink has been transferred will be described.

  As described above, the adhesive 63 a of the adhesive layer 63 has the same color as the ink remaining portion 36 a of the ink layer 36 of the ink ribbon 30. For this reason, when the ink ribbon 30 to which the ink has been transferred is observed from the surface 42b side, the region overlapping the adhesive 63a of the adhesive layer 63 of the tape 42 in the ink removal portion 36b of the ink layer 36 (FIG. 7A). The region indicated by the reference numeral 36 b in FIG. 6B is visually recognized as a region having the same color as the ink remaining portion 36 a of the ink layer 36. For this reason, it is impossible to distinguish the region of the ink missing portion 36 b of the ink layer 36 that overlaps the adhesive 63 a of the adhesive layer 63 and the ink remaining portion 36 a of the ink layer 36.

  Accordingly, as in the case of the first embodiment shown in FIGS. 1 to 4, the region that can be visually recognized from the outside of the ink removal portion 36 b of the ink layer 36 overlaps with the opening 63 b of the adhesive layer 63. Only the region (region located within the solid line among the regions indicated by reference numeral 36b in FIG. 7A). For this reason, when the ink ribbon 30 to which the ink has been transferred is observed from the outside, it is possible to prevent the entire shape of the ink missing portion 36b of the ink layer 36 from being visually recognized. ID information can be prevented from being specified.

  Next, consider the case where the tape 42 is peeled from the ink ribbon 30 that has been subjected to ink transfer. As described above, the adhesive force between the ink layer 36 of the ink ribbon 30 and the tape 42 is greater than the adhesive force between the ink layer 36 of the ink ribbon 30 and the base material layer 35. An adhesive layer 63 is configured. For this reason, when the tape 42 is peeled from the ink ribbon 30 after the ink transfer, as shown in FIG. 8A, the ink remaining portion 36a of the ink layer 36 corresponds to the adhesive 63a of the adhesive layer 63. The portion (the portion bonded to the adhesive 63a) remains on the tape 42 side. On the other hand, as shown in FIG. 8B, the portion of the ink remaining portion 36 a of the ink layer 36 corresponding to the opening 63 b of the adhesive layer 63 (the portion not bonded to the adhesive 63 a) is the base material layer 35. Remain on the side.

  FIG. 8C is a diagram illustrating a case where the ink remaining portion 36a remaining on the base material layer 35 side is viewed from above. As shown in FIG. 8C, in this case, the remaining ink portion 36 a of the ink layer 36 is removed according to the geometric pattern of the adhesive layer 63 of the tape 42. For this reason, the pattern of the ink missing portion 36 b formed corresponding to the ID information is destroyed according to the geometric pattern of the adhesive layer 63 of the tape 42. As a result, it is possible to prevent the ID information printed on the card 15 from being specified from the ink missing portion 36b of the ink layer 36.

  In addition, as for the ink remaining portion 36a remaining on the tape 42 side, the pattern of the ink missing portion 36b formed corresponding to the ID information is the same as in the case of the ink remaining portion 36a remaining on the base layer 35 side. The tape 42 is broken according to the geometric pattern of the adhesive layer 63. In the remaining ink portion 36a remaining on the tape 42 side, the adhesive 63a and the remaining ink portion 36a are of the same color. For this reason, when the tape 42 is viewed from the surface 42 a side, only the geometric pattern of the adhesive layer 63 is visible. That is, the pattern of the broken ink removal portion 36b is not visually recognized. This can further prevent the ID information printed on the card 15 from being specified more firmly.

  In the present embodiment, an example in which the tape base material 62 is formed from a transparent material is shown. However, the present invention is not limited to this, and the tape base material 62 may be formed of a light-shielding material. As a result, it is possible to more firmly prevent the ID information printed on the card 15 from being specified from the ink missing portion 36b of the ink layer 36.

  In the first and second embodiments of the present invention, an example in which only one of the tape base material and the adhesive layer of the tape has a predetermined geometric pattern is shown. However, the present invention is not limited to this, and both the tape base material and the adhesive layer of the tape may have a predetermined geometric pattern. In this case, the tape base material and the adhesive layer may have the same geometric pattern, or the tape base material and the adhesive layer may have different geometric patterns. When the tape base material and the adhesive layer have the same geometric pattern, such a geometric pattern is formed, for example, by punching the tape base material and the adhesive layer together with a mold having a predetermined shape.

Third Embodiment Next, with reference to FIGS. 9 and 10, a third embodiment of the present invention will be described. FIG. 9A is a cross-sectional view showing a tape according to the third embodiment of the present invention, and FIG. 9B is a perspective view showing the tape according to the third embodiment of the present invention. FIG. 10A is a cross-sectional view showing the ink ribbon to which the tape is bonded in the third embodiment of the present invention, and FIG. 10B is a cross-sectional view showing the ink ribbon peeled from the tape. FIG. 10C is a plan view showing the ink ribbon peeled from the tape.

  In the third embodiment shown in FIGS. 9 and 10, the tape supplied from the tape supply unit has a tape base material and adhesive layers provided on both sides of the tape base material. Among them, the adhesive layer on the side of the ink ribbon in contact with the ink layer is different only in that it has a predetermined geometric pattern, and other configurations are substantially the same as those of the first embodiment shown in FIGS. is there. In the third embodiment shown in FIG. 9 and FIG. 10, the same parts as those in the first embodiment shown in FIG. 1 to FIG.

  First, the structure of the tape 42 in this embodiment will be described with reference to FIGS. As shown in FIG. 9A, the tape 42 includes a tape base material 72, and a first adhesive layer 73 and a second adhesive layer 74 provided on both sides of the tape base material 72. Of these, the first adhesive layer 73 is provided on the side of the tape substrate 72 that contacts the ink layer 36 of the ink ribbon 30. Specifically, as shown in FIG. 2, when the ink ribbon 30 is wound around the take-up portion 24 so that the ink layer 36 is positioned outside the base material layer 35, the first adhesive layer 73 becomes the tape base material 72. On the other hand, the second adhesive layer 74 is located outside the tape base material 72 (see FIG. 9A).

  As in the case of the adhesive layer 63 in the second embodiment shown in FIGS. 6 to 8, the first adhesive layer 73 provided on the inner side of the tape base material 72 is between the adhesive 73a and the adhesive 73a. The first adhesive layer 73 has a predetermined geometric pattern (see FIGS. 9A and 9B).

  Further, as in the case of the first and second embodiments described above, the adhesion between the ink layer 36 of the ink ribbon 30 and the tape 42 causes the ink layer 36 of the ink ribbon 30 and the base material layer 35 to adhere to each other. The adhesive 73a of the first adhesive layer 73 of the tape 42 is configured so as to be larger than the adhesive force between them.

  The material for forming the tape base material 72 of the tape 42 is not particularly limited, and a well-known material used for holding an adhesive in a general tape is used. In the present embodiment, for example, a transparent material is used as a material for forming the tape base material 72.

  Next, the operation of the present embodiment having such a configuration will be described. The operation of printing the ID information on the card 15 using the ink ribbon 30 is the same as in the case of the first embodiment, and a description thereof will be omitted. Here, an operation by adhering the tape 42 to the ink ribbon 30 to which ink has been transferred will be described.

  First, the ink ribbon 30 to which ink has been transferred is wound around the winding unit 24. The ink ribbon 30 is located on the inner side (the center side of the winding unit 24) than the ink ribbon that is wound around the winding unit 24 thereafter. Accordingly, in the following description, the ink ribbon that is previously wound around the winding portion 24 is referred to as an inner ink ribbon 30A (see FIG. 10A).

Next, the tape 42 from the tape supply unit 41 is taken up by the take-up unit 24, whereby the tape 42 is wound on the inner ink ribbon 30A as shown in FIG. The tape is located on the inner side of the tape that is subsequently wound around the winding portion 24. Therefore, in the following description, the tape wound on the inner ink ribbon 30A is referred to as the inner tape 42A.
A first adhesive layer 73 is provided on the inner surface of the tape base 72 of the inner tape 42 </ b> A. For this reason, the inner tape 42 </ b> A and the inner ink ribbon 30 </ b> A are bonded by the first adhesive layer 73. .

Thereafter, the ink ribbon 30 is further wound on the inner tape 42A. In the following description, the ink ribbon wound on the inner tape 42A is referred to as the outer ink ribbon 30B.
The second adhesive layer 74 is provided on the outer side of the tape base 72 of the inner tape 42 </ b> A. For this reason, the inner tape 42 </ b> A and the outer ink ribbon 30 </ b> B are bonded by the second adhesive layer 74.

  In the present embodiment, preferably, the adhesion between the inner tape 42A and the base layer 35 of the outer ink ribbon 30B is between the ink layer 36 and the base layer 35 of the inner ink ribbon 30A. The second adhesive layer 74 of the inner tape 42 </ b> A is configured so as to be larger than the adhesive strength of the inner tape 42 </ b> A. That is, an adhesive material for forming the second adhesive layer 74 is selected so as to realize such adhesion. For this reason, as will be described later, when the wound body of the ink ribbon 30 solidified by the adhesive layers 73 and 74 of the tape 42 is disassembled, the outer ink ribbon 30B is separated from the inner tape 42A. Further, the ink layer 36 of the inner ink ribbon 30 </ b> A is peeled off from the base material layer 35.

Next, the tape 42 is further wound on the outer ink ribbon 30B. In the following description, the tape wound around the outer ink ribbon 30B is referred to as the outer tape 42B.
The first adhesive layer 73 is provided on the inner side of the tape base 72 of the outer tape 42B. For this reason, the outer tape 42B and the outer ink ribbon 30B are bonded by the first adhesive layer 73.

  Thereafter, the ink ribbon 30 and the tape 42 are sequentially wound around the winding unit 24. In this case, the tape base material 72 of the tape 42 is provided with the first adhesive layer 73 and the second adhesive layer 74 on both sides thereof. Therefore, the ink ribbon 30 wound up by the winding unit 24 is It is adhered to the tape 42 on both the inside and outside. Therefore, a wound body of the ink ribbon 30 that is solidified by the adhesive layers 73 and 74 of the tape 42 is formed in the winding portion 24. As a result, it is possible to prevent the ink missing portion 36b of the ink layer 36 of the ink ribbon 30 to which the ink has been transferred from being visually recognized, thereby preventing identification of the ID information printed on the card 15. Can do.

Next, consider a case where the wound body of the ink ribbon 30 solidified by the adhesive layers 73 and 74 of the tape 42 is disassembled by some means.
In the present embodiment, the adhesion force between the ink layer 36 of the inner ink ribbon 30A and the inner tape 42A is greater than the adhesion force between the ink layer 36 of the inner ink ribbon 30A and the base material layer 35. The first adhesive layer 73 of the inner tape 42A is configured so as to be larger. Further, the adhesive force between the inner tape 42A and the base layer 35 of the outer ink ribbon 30B is larger than the adhesive force between the ink layer 36 and the base layer 35 of the inner ink ribbon 30A. The second adhesive layer 74 of the inner tape 42A is configured. For this reason, when the wound body of the ink ribbon 30 is disassembled, a portion of the ink remaining portion 36a of the ink layer 36 of the inner ink ribbon 30A corresponding to the adhesive 73a of the first adhesive layer 73 (adhesive 63a The portion adhered to the inner tape 42A remains on the inner tape 42A side. On the other hand, of the ink remaining portion 36a of the ink layer 36 of the inner ink ribbon 30A, the portion corresponding to the opening 73b of the first adhesive layer 73 (the portion not bonded to the adhesive 73a) is on the substrate layer 35 side. It remains (see FIG. 10B).

  FIG. 10C is a diagram showing a case where the ink remaining portion 36a remaining on the base material layer 35 side of the inner ink ribbon 30A is viewed from above. As shown in FIG. 10C, in this case, the ink remaining portion 36a of the ink layer 36 is removed according to the geometric pattern of the first adhesive layer 73 of the inner tape 42A. For this reason, the pattern of the ink missing portion 36 b formed corresponding to the ID information is destroyed according to the geometric pattern of the first adhesive layer 73. As a result, it is possible to prevent the ID information printed on the card 15 from being specified from the ink missing portion 36b of the ink layer 36.

  Further, the remaining ink portion 36a remaining on the inner tape 42A side is also formed corresponding to the ID information as in the case of the remaining ink portion 36a remaining on the base material layer 35 side of the inner ink ribbon 30A. Further, the pattern of the ink missing portion 36 b is destroyed according to the geometric pattern of the first adhesive layer 73. As a result, it is possible to prevent the ID information printed on the card 15 from being specified from the ink missing portion 36b of the ink layer 36.

  In the present embodiment, an example in which the tape base material 72 is formed from a transparent material is shown. However, the present invention is not limited to this, and the tape base material 72 may be formed of a light-shielding material. As a result, it is possible to more firmly prevent the ID information printed on the card 15 from being specified from the ink missing portion 36b of the ink layer 36.

  Moreover, in this Embodiment, the example in which only the 1st contact bonding layer 73 provided inside the tape base material 72 has a predetermined geometric pattern was shown. However, the present invention is not limited to this, and any of the tape base material 72 and the second adhesive layer 74 provided outside the tape base material may have a predetermined geometric pattern. In this case, the tape base material 72 and the adhesive layers 73 and 74 may have the same geometric pattern, or the tape base material 72 and the adhesive layers 73 and 74 have different geometric patterns. Also good. When the tape base material 72 and the adhesive layers 73 and 74 have the same geometric pattern, such a geometric pattern is, for example, the tape base material 72 and the adhesive layer 73, It is formed by punching 74 together.

  In the first to third embodiments of the present invention, the tape base material or the adhesive layer of the tape 42 is provided with a plurality of openings arranged in a predetermined pattern. An example is shown in which the layers have a predetermined geometric pattern. In this case, the shape of the opening is not limited to an ellipse as shown in the figure, and openings having various shapes such as a polygon and a cloud can be provided. Moreover, the pattern which arrange | positions a several opening part is not restricted to the regular arrangement | positioning pattern as shown in a figure, A some opening part may be arrange | positioned by the irregular pattern.

Fourth Embodiment Next, a fourth embodiment of the present invention will be described with reference to FIGS. FIG. 11 is a cross-sectional view showing a tape according to the fourth embodiment of the present invention. FIG. 12A is a plan view showing an ink ribbon to which a tape is adhered in the fourth embodiment of the present invention, and FIG. 12B is a diagram in which the tape shown in FIG. 12A is adhered. 12C is a cross-sectional view of the ink ribbon taken along line XII-XII, and FIG. 12C shows a case where the base layer of the ink ribbon is peeled from the ink ribbon to which the tape shown in FIG. It is sectional drawing.

  In the fourth embodiment shown in FIGS. 11 and 12, the tape supplied from the tape supply unit is bonded to the tape base material and the side of the tape base material that contacts the ink layer of the ink ribbon. 1 except that the tape base material includes a light shielding layer that shields light, and the adhesive layer has the same color as the ink layer of the ink ribbon. This is substantially the same as the first embodiment shown in FIG. In the fourth embodiment shown in FIGS. 11 and 12, the same parts as those in the first embodiment shown in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

  First, the structure of the tape 42 in the present embodiment will be described with reference to FIG. As shown in FIG. 11, the tape 42 includes a tape base material 82 and an adhesive layer 83 provided on the side of the tape base material 82 that contacts the ink layer 36 of the ink ribbon 30. Among these, the tape base material 82 includes a light shielding layer 82a that shields light. The method for forming the light shielding layer 82 a in the tape base material 82 is not particularly limited. For example, the light shielding layer 82 a can be formed by dispersing light shielding particles in the tape base material 82. For example, as in the case of a so-called silver tape, silver or silver alloy particles can be dispersed in the tape base material 82 to make the tape base material 82 light-shielding.

  The adhesive layer 83 has the same color as the ink remaining portion 36 a of the ink layer 36 of the ink ribbon 30. Here, the “same color” means that the adhesive layer 83 and the ink remaining portion 36a are adjacent to each other and observed as in the case of the base material portion 52a in the first embodiment. This means that the color of the adhesive layer 83 and the color of the ink remaining portion 36a are similar to the extent that the boundary line between the ink remaining portion 36a and the ink remaining portion 36a is indistinguishable with the naked eye.

  Further, as in the case of the first embodiment described above, the adhesion between the ink layer 36 of the ink ribbon 30 and the tape 42 is such that the adhesion between the ink layer 36 of the ink ribbon 30 and the base material layer 35. The adhesive of the adhesive layer 83 of the tape 42 is configured to be greater than the force.

  Next, the operation of the present embodiment having such a configuration will be described. The operation of printing the ID information on the card 15 using the ink ribbon 30 is the same as in the case of the first embodiment, and a description thereof will be omitted. Here, an operation by adhering the tape 42 to the ink ribbon 30 to which ink has been transferred will be described.

  As described above, the tape base material 82 includes the light shielding layer 82a that shields light. For this reason, when the ink ribbon 30 to which ink has been transferred is observed from the tape surface 42b side, the ink missing portion 36b of the ink layer 36 is not visually recognized (see FIGS. 12A and 12B). As a result, it is possible to prevent the ID information printed on the card 15 from being specified from the ink missing portion 36b of the ink layer 36.

  Next, consider the case where the tape 42 is peeled from the ink ribbon 30 that has been subjected to ink transfer. As described above, the adhesive force between the ink layer 36 of the ink ribbon 30 and the tape 42 is greater than the adhesive force between the ink layer 36 of the ink ribbon 30 and the base material layer 35. An adhesive layer 83 is configured. For this reason, when the tape 42 is peeled from the ink ribbon 30 after the ink transfer, as shown in FIG. 12C, the ink remaining portion 36a of the ink layer 36 remains on the tape 42 side.

  As described above, the adhesive layer 83 has the same color as the ink remaining portion 36 a of the ink layer 36 of the ink ribbon 30. For this reason, when the ink ribbon 30 to which the ink has been transferred is observed from the surface 42a side of the tape 42, the ink missing portion 36b of the ink layer 36 is visually recognized as a region having the same color as the ink remaining portion 36a of the ink layer 36. The For this reason, it can prevent that the shape of the ink omission part 36b of the ink layer 36 is visually recognized, and it can prevent that ID information printed on the card | curd 15 is specified by this.

  Further, unlike the case of the above-described comparative embodiment shown in FIG. 5, the tape base material 82 includes a light shielding layer 82a that shields light. For this reason, the shape of the ink missing portion 36b is not recognized based on a slight difference in the density of transmitted light. As a result, it is possible to more firmly prevent the ID information printed on the card 15 from being specified from the ink ribbon 30 to which ink has been transferred.

  In the first, second, and fourth embodiments of the present invention, the example in which the adhesive layer is provided only on one side of the tape base material is shown. However, the present invention is not limited to this, and in the first, second, and fourth embodiments of the present invention, as in the case of the third embodiment of the present invention, bonding is performed on both sides of the tape substrate. A layer may be provided. As a result, it is possible to form a wound body of the ink ribbon that has been hardened by the adhesive layer of the tape, thereby more firmly preventing the shape of the ink missing portion of the ink ribbon from being visually recognized. For this reason, it can prevent more firmly that ID information printed on the card | curd 15 from the ink ribbon 30 after ink transfer is specified.
