Description

  The present invention relates to a print medium that is wound in advance in a roll shape, and a printing method and a printing apparatus that print on the print medium.

  Conventionally, a tape piece (printed matter) is cut by cutting a long tape after printing a desired drawing pattern including arbitrary characters, pictures, etc. on a long tape (print medium) which is wound in advance in a roll shape. A printing device such as a label printer that can be easily created is used. Further, the above long tape wound in a roll shape for use in a label printer is manufactured and sold.

  The long tape described above is wound in a roll shape (for example, a spiral shape) as roll paper and stored in a tape cartridge so that the long tape can be cut to an arbitrary length after printing. When printing is started, a portion of the ink ribbons stacked on the long tape heated by the thermal head is thermally transferred to the surface of the long tape as a drawing pattern. After the printing is completed, the long tape wound with the ink ribbon is cut by a cutter, so that a tape piece is cut out from the long tape.

  There are various types of long tapes, but there are many tapes that have a release paper overlaid on the tape body to prevent dust from adhering to the adhesive layer applied to the back surface of the tape body. After peeling the release paper from the tape piece created after printing and cutting the tape, the tape body is attached to the object as a seal.

  For example, as shown in FIG. 1, the long tape 30 includes a tape body 31, an adhesive layer 32, and a release paper 33. The ink ribbon 40 is overlaid on the printing surface 31a, which is the surface of the tape body 31 opposite to the adhesive layer 32 side.

  An adhesive layer 32 is applied to the tape body 31, and the tape body 31 and the adhesive layer 32 are sandwiched between the release paper 33 and the ink ribbon 40. Note that the ink ribbon 40 is omitted when printing is performed on the tape body 31 without using an ink ribbon such as an inkjet.

  Since the long tape described above is wound in a roll and stored in the tape cartridge, a curl occurs after it is unwound from the tape cartridge. The curl of the long tape remains as a curl on a tape piece created by printing and cutting the long tape. Due to this curl, the tape piece naturally curls. For this reason, when the user actually peels off the release paper from the tape piece and then tries to attach the tape body to the object as a seal, there is a problem that the work of peeling off the release paper from the tape piece is troublesome.

It is a figure which shows the tape piece and discarding part produced from the elongate tape in one embodiment of this invention.

Hereinafter, a print medium, a printing method, and a printing apparatus according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a laminated state of a long tape 30 and an ink ribbon 40, which are examples of a print medium which is wound in advance in a roll shape.

  As shown in FIG. 1, the long tape 30 includes a tape body 31, an adhesive layer 32, and a release paper 33. The tape body 31 is an example of the first layer, and the release paper 33 is an example of the second layer.

  An adhesive layer 32 is applied to the back surface of the tape body 31 opposite to the front surface, which is the printing surface 31a. The release paper 33 covers the adhesive layer 32 and is releasably attached to the tape body 31. Thus, the tape body 31 and the release paper 33 are attached to each other.

  The ink ribbon 40 is superposed on the printing surface 31 a of the tape body 31. When printing is performed on the tape body 31 without using the ink ribbon 40 such as an inkjet, the ink ribbon 40 is omitted.

  The material of the tape body 31 is, for example, plastic or paper, but is not particularly limited. Further, the adhesive layer 32 is not particularly limited as long as it has a considerable adhesiveness.

  The release paper 33 contains therein a heat-deformable material that generates a stress that deforms the print medium by being deformed by heat treatment (heating). The heat-deformable material may be one that is temporarily deformed during the heat treatment (heating step described later) and returns to its original shape as the temperature of the heat-deformable material decreases after the heat treatment, For example, plastic deformation may be performed so that the deformation is maintained even when the temperature returns to the temperature before the heat treatment such as normal temperature.

  The heat deformable material may be the material itself of the release paper 33. Further, when the heat-deformable material is located inside the tape body 31, inside the adhesive layer 32, between the tape body 31 and the adhesive layer 32, between the adhesive layer 32 and the release paper 33, etc. It can be said that it is located inside the long tape 30 as in the case where it is contained inside 33.

  The heat-deformable material may be provided so as to be located on the outer surface of the long tape 30, for example, the back surface of the release paper 33 (the surface opposite to the adhesive layer 32 side). In that case, the heat-deformable material may be provided on the entire back surface of the release paper 33, but as in the first modification shown in FIG. 6, the heat-deformable material 33a located on the back surface of the release paper 33 has a long length. The long tape 30 is conveyed in the short direction (the width direction of the long tape 30 and intermittently at intervals in the longitudinal direction (the conveyance direction in which the long tape 30 is conveyed) D1. It may be formed over the whole (or a part) of the direction D2 that intersects the direction. Further, as in the second modified example shown in FIG. 7, the heat-deformable material 33b located on the back surface of the release paper 33 intermittently extends in the longitudinal direction D1 at intervals in the lateral direction D2 of the long tape 30. It may be formed entirely (or partially).

  The heat deformable materials 33a and 33b may be formed to extend obliquely so as to intersect the longitudinal direction D1 and the lateral direction D2 of the long tape 30. Alternatively, the dot-shaped or island-shaped heat-deformable material may be dispersedly formed on the back surface of the release paper 33. In these cases, it can be said that the heat-deformable material is intermittently formed in both the longitudinal direction D1 and the lateral direction D2 of the long tape 30. The heat-deformable material is included in the release paper 33, is the material of the release paper 33 itself, or is in the release paper 33 when it contacts the outer surface of the release paper 33. Further, the heat-deformable material is included in the tape body 31, is a material of the tape body 31 itself, or is in the tape body 31 when it contacts the outer surface of the tape body 31.

  When the release paper 33 is wound on the outer side of the tape body 31 (the side farther from the center of the roll in the rolled state), the long tape 30 is fed out from the rolled state. After that, a curl is formed so that the tape body 31 is on the inside and the release paper 33 is on the outside. Therefore, in such a case, as the heat-deformable material, a material such as polyethylene, which shrinks by heating, is used, so that the release paper 33 shrinks by the heat treatment, which causes the curl of the long tape 30. Will be resolved.

  On the other hand, when the release paper 33 is wound inside the tape body 31 (on the side closer to the center of the roll when wound in a roll), the long tape 30 is unwound from the roll. After being twisted, the tape body 31 has a curl so that the tape body 31 is on the outer side and the release paper 33 is on the inner side. Therefore, in such a case, the heat-deformable material uses a heat-expandable resin, such as polyvinyl chloride, which expands by heating, as a material, so that the release paper 33 expands due to the heat treatment, whereby The winding habit of the measuring tape 30 is eliminated.

FIG. 2 is a plan view showing the printing apparatus 1 according to this embodiment.
As shown in FIG. 2, the printing apparatus 1 is, for example, a label printer including an apparatus body 2, an input unit 3, a display unit 4, an opening/closing lid 5, and a cartridge storage unit 6.

A tape cartridge 17 shown in FIG. 4, which will be described later, is detachably accommodated in the cartridge accommodating portion 6.
FIG. 3 is a control block diagram of the printing apparatus 1 according to this embodiment.

  As shown in FIG. 3, the printing device 1 includes the input unit 3 and the display unit 4, the control unit 5, the ROM (Read Only Memory) 6, the RAM (Random Access Memory) 7, the display unit driving circuit 8, and the printing unit described above. A head drive circuit 9 and a thermal head 10, a conveyance motor drive circuit 11, a conveyance motor 12, a conveyance roller 13, a cutter motor drive circuit 14, a cutter motor 15, and a cutting mechanism 16 which is an example of a cutting unit. Prepare

  The printer 1 prints a desired drawing pattern on the printing surface 31a of the long tape 30 based on the print data, and then cuts the long tape 30 to form an example of a printed matter on which the desired drawing pattern is printed. The tape piece 50 shown in FIG. 4 is prepared. Here, when the deformation process of the long tape 30 by heating described below is performed after printing and cutting, even after the printing and cutting, before the deformation process, the long tape 30 is not the tape piece 50. And The order of printing, transforming, and cutting is not particularly limited.

  The control unit 5 is, for example, a CPU (Central Processing Unit), and responds to a key operation signal from the input unit 3, or a system program stored in advance in the ROM 6, a control program stored in a memory card, or an external device. A control program read from the device is automatically started, and the operation of each circuit unit is controlled by using the RAM 7 as a work memory.

  The control unit 5 includes an input unit 3, a ROM 6, a RAM 7, a display unit drive circuit 8 that drives the display unit 4, a head drive circuit 9 that drives the thermal head 10, and a transport roller 13. The transport motor drive circuit 11 that drives the transport motor 12 and the cutter motor drive circuit 14 that drives the cutter motor 15 that operates the cutting mechanism 16 are connected.

  The ROM 6 is a program for causing the thermal head 10 to print a desired drawing pattern on the long tape 30 by the head drive circuit 9, original data and size information of characters, symbols, pictograms, etc. included in the drawing pattern to be printed, Store print fonts. The ROM 6 also functions as a storage medium that stores a program readable by the control unit 5.

  The RAM 7 is input data that stores print information such as characters, symbols, pictograms included in a desired drawing pattern to be printed, their size, and character spacing, and the size of the tape piece 50 to be created. Functions as a memory. In addition, the RAM 7 functions as a print data memory that stores print pattern data that is generated based on the input print information and that represents a desired drawing pattern, and is displayed on the display unit 4 to display the desired drawing pattern. It also functions as a display data memory or the like that stores the display pattern data indicating The RAM 7 also includes a register, a counter, and the like that temporarily store data necessary for print processing and the like.

  The head drive circuit 9 controls the thermal head 10 based on the printing pattern data stored in the RAM 7, and causes the thermal head 10 to print a desired drawing pattern on the printing surface 31 a of the long tape 30.

  The conveyance motor drive circuit 11 controls the stepper motor based on the printing pattern data stored in the RAM 7 to control the rotation of the conveyance roller 13 and the ribbon winding shaft 19 shown in FIG. During printing on the long tape 30 by, the long tape 30 is conveyed at a desired speed.

  The cutter motor drive circuit 14 controls the operation of the cutting mechanism 16. The cutting mechanism 16 separates the formed tape piece 50 from the long tape 30 by cutting the tape body 31 together with the release paper 33 in the width direction. The cutting mechanism 16 cuts only the tape body 31 of the tape body 31 and the release paper 33 in the width direction so that the tape piece 50 is not separated from the long tape 30 while cutting the tape body 31. Good.

FIG. 4 is a diagram for explaining the printing method according to the present embodiment.
FIG. 5 is an enlarged view in which the vicinity of the thermal head 10 of FIG. 4 is enlarged.
As shown in FIG. 4, inside the tape cartridge 17, a long tape 30 and an ink ribbon 40 are wound around the tape core 18 in a roll shape so as to overlap each other. The state in which the long tape 30 is wound in a roll shape includes not only a state in which it is wound in a circle but also a state in which it is wound in other shapes such as an elliptical shape and a polygonal shape.

  The ink ribbon 40 may be wound around a shaft different from that of the tape core 18, and may be fed together with the long tape 30 that is fed along with printing from the state of being wound on the tape core 18.

  The long tape 30 and the ink ribbon 40 are fed out from the tape cartridge 17 by a conveyance roller 13 (see FIG. 3) not shown in FIG. 4, and a desired drawing pattern is lengthened via the ink ribbon 40 by the thermal head 10 described above. It is transferred to the measuring tape 30 (printing process).

  After that, the long tape 30 that has undergone the printing process is separated into the ink ribbon 40 by the ribbon separating unit roller 20 and then cut by the cutting mechanism 16 (cutting process) to be cut out as a tape piece 50. The ink ribbon 40 separated from the long tape 30 is wound in the tape cartridge 17 by the ribbon winding shaft 19.

  In the printing process, the thermal head 10 prints as described above by heating the ink ribbon 40 (long tape 30) as indicated by the four arcs in FIG. Conducts heat to the release paper 33 through the tape body 31 and the adhesive layer 32. As a result, the release paper 33 contracts as described above. In the comparative example in which the release paper 33 (long tape 30) does not shrink (deform), the tape piece 50 created after printing and cutting is the release paper 33 wound outside the tape body 31 as it is. The tape is curled as shown by a chain double-dashed line 50-0 in FIG. On the other hand, in the present embodiment, the release paper 33 contracts so as to eliminate the curl of the long tape 30, so that the tape piece 50 shown by the solid line in FIG. 4 does not curl or the curl amount decreases. As described above, in the present embodiment, the printing step includes a step (deformation step) of deforming the long tape 30 by heating so as to eliminate the curl of the long tape 30 in a rolled state. Also serves as.

  Here, if the release paper 33 is peeled from the tape body 31 when the release paper 33 contracts, the entire long tape 30 cannot be deformed. Therefore, the tape body 31 and the release paper 33 are heated by heating. It is adhered by an adhesive layer 32 so as not to come off.

  Further, the long tape 30 is wound around the tape core 18 so that the portion near the tape core 18 at the center of the roll has a smaller curvature than the portion far from the tape core 18. As a result, regarding the winding habit of the long tape 30, the curl amount in the portion close to the tape core 18 is larger than that in the portion far from the tape core 18 (curling is performed so that the radius of curvature becomes smaller).

  Therefore, in the long tape 30, for example, the release paper 33 has a larger amount of deformation due to heating than a portion far from the tape core 18 than a portion far from the tape core 18 than a portion far from the tape core 18. It is preferable to increase the amount of the heat-deformable material contained per unit area of. The amount of the heat deformable material may be increased stepwise or may be increased gradually (continuously).

  Further, in the deforming step, for example, the heating amount of the thermal head 10 is set so that the heating amount of the thermal head 10 becomes larger than the portion of the long tape 30 that is closer to the tape core 18 than the far portion. It is advisable to increase stepwise or gradually from the time of heating a portion far from the heating point to the heating of a portion near it. Alternatively, the transport speed of the long tape 30 may be gradually or gradually decreased from the time of heating a portion far from the tape core 18 to the time of heating a near portion thereof.

  In the above description, an example in which the printing process of the long tape 30 by the thermal head 10 also serves as the deforming process has been described, but the deforming process is performed using a heating unit such as a heater independent of the thermal head 10. Good. In that case, in the deforming step, it is advisable to heat the long tape 30 from the opposite side with the long tape 30 sandwiched between the long tape 30 and the printing. When the deforming process is performed using a heating unit such as a heater that is independent of the thermal head 10, a printing unit that does not heat the long tape 30 such as an inkjet may be used as the printing unit.

  As in the third modified example shown in FIG. 8, for example, on the downstream side of the cutting mechanism 16 in the transport direction (on the right side of FIG. 8), the lower roller 13a and the lower roller 13a that face each other with the long tape 30 (tape piece 50) interposed therebetween, When the transport roller 13 having the upper roller 13b is disposed, the lower roller 13a can be caused to function as the above-described heating unit that heats the long tape 30 by providing the lower roller 13a with a heat source.

  As shown in FIG. 9, when, for example, a discarded portion 60 that is not used as the tape piece 50 is created between the created tape pieces 50, two second tape pieces 50 that are used as the tape piece 50 of the long tape 30. One part (first part that is used without being discarded after printing) 30-1 and 30-1 and a second part surrounded by these that is not used as the tape piece 50 (is discarded without being used after printing). The second part) 30-2 and the second part) are cut off. When the long tape 30 is cut, both the tape body 31 and the release paper 33 may be cut, or only the tape body 31 of the tape body 31 and the release paper 33 may be cut. Good.

  When cutting between the two first portions 30-1 and 30-1 and the second portion 30-2, when the deformation step is performed independently of the printing step, in the printing step, the long tape 30 is cut. Printing is performed by heating, for example, a print area corresponding to a desired drawing pattern in the first portion 30-1, but in the transforming step, a non-print area (for example, ABCDE) in the first portion 30-1 is used. Alternatively, the long tape 30 is deformed so that printing is not performed on a portion where FGHIJ is not printed (for example, an unintended printing portion does not occur on the tape body 31 or the color of the tape body 31 does not change color). As described above, the long tape 30 may be heated. In the deforming step, the long tape 30 may be deformed by heating only the second portion 30-2 of the long tape 30, or the first portion 30-1 and the second portion 30-2. The long tape 30 may be deformed by heating both of them.

  The long tape 30 which is an example of the print medium wound in advance in the roll shape according to the present embodiment described above is deformed by heating so as to eliminate the curl. Further, in the printing method according to the present embodiment, printing is performed on the long tape 30 (printing step), and the long tape 30 is deformed by heating (deformation) so as to eliminate the curl of the long tape 30. Process). Further, the printing apparatus 1 according to the present embodiment includes a head drive circuit 9 and a thermal head 10, which are examples of a printing unit that prints on the long tape 30 wound in advance in a roll shape, and the long tape 30. The head drive circuit 9 and the thermal head 10, which are an example of a heating unit that deforms the long tape 30 by heating so as to eliminate the habit, are provided. By eliminating the curl of the long tape 30 as described above, the curl of the long tape 30 which is fed out from a rolled state is an example of a printed matter created from the long tape 30. It is possible to prevent the tape piece 50 from remaining as a curl. Therefore, according to the present embodiment, it is possible to prevent the tape piece 50 from winding.

  Further, in the long tape 30 according to the present embodiment, a portion that is closer to the center of the roll (tape core 18) in a state of being wound in a roll has a larger amount of deformation due to heating than a far portion. Is formed in. Further, in the printing method according to the present embodiment, in the deforming step, the heating amount of the long tape 30 is larger in a rolled portion than in a distant portion from the roll center. Heat to. By the way, the long tape 30 wound in a roll shape is wound around the tape core 18 so that a portion closer to the center of the roll has a smaller curvature than a portion farther from the center. As a result, the curl of the long tape 30 has a greater amount of curl in a portion closer to the tape core 18 than in a portion farther from the tape core 18 (curls with a smaller radius of curvature). However, as described above, the long tape 30 is formed such that the amount of deformation due to heating is larger in a portion closer to the center of the roll in a rolled state than in a portion farther from the center of the roll or the amount of heating. By increasing the value, it is possible to prevent the tape piece 50 formed from the portion of the long tape 30 that is close to the center of the roll from having a large curl.

  Further, in the present embodiment, the long tape 30 contains a heat-deformable material that is deformed by heating. Further, the heat-deformable material 33a of the long tape 30 according to the first modified example (FIG. 6) of the present embodiment is intermittently formed at intervals in the longitudinal direction D1 of the long tape 30. Further, the heat-deformable material 33b of the long tape 30 according to the second modified example (FIG. 7) of the present embodiment is intermittently formed at intervals in the lateral direction D2 of the long tape 30. Therefore, it is possible to suppress the winding tendency of the tape piece 50 while suppressing the consumption of the heat deformable materials 33a and 33b.

  Further, the long tape 30 according to the present embodiment includes a tape body 31 that is an example of the first layer and a release paper 33 that is an example of the second layer, which are attached to each other. The release surface 33 is a printing surface 31a on which printing is performed, and the release paper 33 includes a heat deformable material that is deformed by heating. In this way, by deforming the long tape 30 by deforming the release paper 33, as compared with the case of deforming the long tape 30 by deforming the tape body 31 having the printing surface 31a, the printing surface 31a is deformed. It is possible to prevent the printing accuracy from deteriorating due to the deformation of the printing area. Further, since the release paper 33 is deformed more than the tape body 31, a gap is likely to be formed between the tape body 31 and the release paper 33, so that the release paper 33 can be easily peeled from the tape body 31 and the adhesive layer 32. You can also

  Further, in the long tape 30 according to the present embodiment, the tape body 31 and the release paper 33 are attached so as not to come off due to deformation due to heating. Therefore, along with the deformation of the release paper 33, the tape body 31 can be deformed so as to eliminate the curl, and the adhesive layer 32 is exposed by peeling the adhesive bond between the tape body 31 and the release paper 33. Can be prevented.

  Further, in the printing method according to the present embodiment, in the deforming step, the long tape 30 is heated so that the tape body 31 and the release paper 33 are not separated by the deformation and the release paper 33 is deformed. Therefore, compared with the case where the long tape 30 is deformed by deforming the tape body 31 having the printing surface 31a, it is possible to prevent the printing accuracy from being deteriorated due to the deformation of the printing area of the printing surface 31a. .. Further, the tape body 31 can be deformed so as to eliminate the curl due to the deformation of the release paper 33, and the adhesive layer 32 is exposed by the peeling of the bonding between the tape body 31 and the release paper 33. Can be prevented.

  Further, in the printing method according to the present embodiment, when printing is performed on the long tape 30, the long tape 30 is deformed by heating the long tape 30 for printing. In addition, in the printing apparatus 1 according to the present embodiment, the printing unit including the head drive circuit 9 and the thermal head 10 also serves as the heating unit. Therefore, since the long tape 30 can be deformed by using the configuration of the thermal head 10 or the like used for printing, it is possible to prevent the configuration of the printing apparatus 1 from becoming complicated.

  Further, in the printing method according to the present embodiment, in the deforming step, the long tape 30 is heated from the opposite side with the long tape 30 sandwiched between the long tape 30 and the printing. Therefore, by deforming the long tape 30 by deforming the heat-deformable material arranged on the opposite side of the long tape 30 from the printing surface 31a, the printing area of the printing surface 31a is deformed. It can prevent the printing system from deteriorating. Further, since the heat-deformable material is likely to receive heat, the amount of heat generated during heating can be suppressed. Further, by performing the deforming step independently of the printing step, it is possible to uniformly heat the long tape 30 in the deforming step as compared with the case where only the printing area of the long tape 30 is heated by the thermal head 10. It will be possible.

  Moreover, when the long tape 30 is deformed, the printing method according to the present embodiment prevents printing in a non-printing area of the first portion 30-1 that is used without being discarded after printing. The long tape 30 is heated so that the long tape 30 is deformed. Therefore, it is possible to deform the long tape 30 while preventing the printing accuracy from deteriorating due to printing in the printing area of the printing surface 31a.

  Further, in the printing method according to the present embodiment, when the long tape 30 is deformed, the second portion 30-2 that is discarded after being used and not used is deformed by heating. Therefore, since the deformation of the second portion 30-2 contributes to the deformation of the long tape 30, compared with the case where only the first portion 30-1 of the first portion 30-1 and the second portion 30-2 is heated. Then, the heating of the first portion 30-1 is omitted, the heating amount of the first portion 30-1 is made smaller than that of the second portion 30-2, or the first portion 30-1 and the second portion 30-2. It becomes possible to reduce or reduce the common heating amount in 30-2. Therefore, it is possible to prevent the printing accuracy from deteriorating due to the printing performed on the printing target area of the printing surface 31a.

  Further, in the printing method according to the present embodiment, in the printing process, printing is performed on the first portion 30-1 of the tape body 31 of the long tape 30, and in the deforming process, the release paper 33 is deformed to change the length. The tape measure 30 is deformed, and in the cutting step, at least the tape body 31 of the tape body 31 and the release paper 33 is cut between the second portion 30-1 and the first portion 30-1.
