Description

The present invention relates to a tape unit that is affixed to a discharge port forming surface during distribution or the like, and a liquid ejection head to which the tape unit is affixed.

  In some inkjet recording apparatuses, a recording head is provided with an ejection port, and ink is ejected from the ejection port for recording. In such a recording head, the wall surface of the portion where the discharge port is formed may be thin. Further, when the recording head is distributed, a protective tape may be attached around the discharge port in order to suppress the occurrence of ink leakage from the discharge port during the distribution.

  At this time, if the adhesive force is excessively strong in the portion of the protective tape that is attached to the portion where the strength of the recording head is low, the strength of the recording head may be affected when the protective tape is peeled off. For example, due to the strong adhesive force of the protective tape, the coating of the electrical wiring tape may be peeled off when the protective tape is peeled off. However, if the adhesive force of the protective tape is excessively weak, the protective tape may be peeled off from the recording head during the distribution of the recording head, and ink may leak from the ejection port.

  Therefore, Patent Document 1 discloses a protective tape that can partially weaken the adhesive force. Patent Document 1 discloses a protective tape partially dimpled. Dimple processing is partially applied to the protective tape, so that unevenness is partially formed on the surface of the protective tape to be attached, and protection is achieved by reducing the contact area between the protective tape and the recording head. The adhesive strength by the tape can be partially weakened.

JP 2007-313890 A

  However, like the protective tape disclosed in Patent Document 1, when the protective tape is dimpled to form irregularities, the protective tape bends unexpectedly at the distribution stage, and thereby A fold or the like may be formed. If the protective tape is circulated with folds or the like formed, the protective tape may be peeled off. If the protective tape is peeled off from the recording head during the distribution, the ink may leak from the ejection port.

The present invention has been made in view of the above circumstances, while suppressing that the bending or creases occur, and an object thereof is to provide a pasted liquid discharge head of the tape unit and the tape unit adhesive is weakened partially.

The tape unit of the present invention is a tape unit that is attached to a discharge port forming surface on which the discharge port is formed in a liquid discharge head that discharges liquid from the discharge port, and is capable of closing the discharge port. An adhesive material and a non-adhesive member on one surface side of the material and the base material, the adhesive material is attached to the discharge port forming surface, and the base material is attached to the discharge port forming surface. The tag member extends in one direction from the portion to be pasted, and a tag member is attached to the end in the one direction, and the non-adhesive member is the region of the base material between the portion and the tag member , It arrange | positions in the several position in one surface of a base material, It is characterized by the above-mentioned.

  According to the present invention, when the adhesion by the tape unit is adjusted, it can be performed without changing the shape of the tape unit, so that the attached tape unit can be prevented from being unexpectedly peeled off.

  Hereinafter, a protective tape according to an embodiment of the present invention and a recording head to which the protective tape is attached will be described.

(First embodiment)
FIG. 1A is a perspective view of the recording head 101 in a state in which the protective tape (tape unit) 120a according to the first embodiment of the present invention is not attached, and FIG. 1B is a protective tape 120a. FIG. 3 is a perspective view of the recording head 101 in a state where is attached.

  The recording head (liquid ejection head) 101 includes an ink storage container 102 that stores ink, and a recording element substrate (element substrate) 103 that performs recording by discharging ink stored in the ink storage container 102. .

  FIG. 2 is a perspective view of the recording element substrate 103 in the recording head 101 to which the protective tape 120a according to the first embodiment is attached. In FIG. 2, in order to explain the internal configuration of the recording element substrate 103, a part of the recording element substrate 103 is shown broken away. The recording element substrate 103 is formed by attaching a flow path forming member 111 to a silicon substrate 110. A liquid chamber 30 is defined in the silicon substrate 110 of the recording element substrate 103. In the liquid chamber 30, ink as a liquid ejected from the recording head 101 is stored. Further, inside the liquid chamber 30, a recording element (element) 31 is provided that imparts energy to the ink in order to discharge the ink stored in the liquid chamber 30 from the discharge port 112. In addition, the recording element substrate 103 is formed with electrode pads 106 that are formed at end portions of wiring extending from the recording element 31 to transmit electric energy to the recording element 31 and through which current is transferred.

  In this embodiment, the recording element substrate 103 uses an electrothermal conversion element as the recording element 31 that generates energy for ejecting ink. By supplying power to each electrothermal conversion element, film boiling occurs in the ink stored in the liquid chamber 30. In addition, electrical wiring for transmitting a current to the recording element 31 is disposed on the recording element substrate 103. Electric wiring is formed on the recording element substrate 103 by a film forming technique. In addition, an ink supply port 107 for supplying ink to a plurality of ink flow paths is formed in the recording element substrate 103 so as to penetrate the recording element substrate 103.

  On the surface side of the recording element substrate 103, a flow path forming member 111 in which a plurality of ink flow paths corresponding to the electrothermal conversion elements and a plurality of discharge ports 112 are formed is attached. The flow path forming member 111 is formed with a discharge port 112 that communicates with the liquid chamber 30 and discharges ink stored in the liquid chamber 30. An ejection port 112 for ejecting ink is formed at a position corresponding to the recording element 31 disposed in the liquid chamber 30. A plurality of discharge ports 112 are formed in the flow path forming member 111, and the plurality of discharge ports 112 are arranged in the X direction (first direction) in FIG. 2 to form a discharge port array. The ink to which thermal energy is given by driving the recording element 31 causes film boiling inside the liquid chamber 30, and thereby the ink is ejected from the ejection port 112 toward the recording medium.

  Around the recording element substrate 103, an electric wiring tape 105 for transmitting a drive signal or the like from the main body side of the ink jet recording apparatus to the recording element substrate 103 is disposed. The recording element substrate 103 and the electrical wiring tape 105 are electrically connected, and an electrical connection portion between them is provided with a sealing portion 104 for protecting the wiring.

  As shown in FIG. 1B, a protective tape 120a is affixed around the ejection port 112 in the recording element substrate 103. That is, the protective tape 120a is affixed to the discharge port forming surface 160 on which the discharge port 112 is formed in the recording element substrate 103.

  FIG. 3 shows a perspective view of an ink jet recording apparatus 1000 on which the recording head 101 shown in FIG. 2 is mounted. In the ink jet recording apparatus 1000 of the present embodiment, recording is performed by mounting the recording head 101 shown in FIG. The carriage 211 is guided so as to be movable in the main scanning direction indicated by an arrow A along the guide shaft 206. The guide shaft 206 is disposed so as to extend along the width direction of the recording medium. The ink jet recording head cartridge 100 mounted on the carriage 211 performs recording while scanning in the direction intersecting the transport direction in which the recording medium is transported. As described above, the ink jet recording apparatus 1000 is a so-called serial scan type ink jet recording apparatus that records an image with the movement of the ink jet recording head cartridge 100 in the main scanning direction and the conveyance of the recording medium in the sub scanning direction. . A plurality of recording heads 101 corresponding to the types of ink that can be ejected from the ink jet recording apparatus are mounted on the carriage 211. After the recording medium is stacked on the paper feeding unit 215, the recording medium is transported in the sub-scanning direction indicated by the arrow B by the transport roller.

  The ink jet recording apparatus 1000 alternately repeats a recording operation for ejecting ink while moving the recording head 101 mounted on the carriage 211 in the main scanning direction and a conveying operation for conveying the recording medium in the sub scanning direction. . As a result, images are sequentially recorded on the recording medium. When ink is ejected, a current is supplied from the inner lead 122 to the electrode pad 106 at a predetermined timing according to the recording data. When a current is supplied to the electrode pad 106, a current is supplied from the electrode pad 106 to the recording element 31 through the wiring. Thus, the recording element 31 is driven by supplying the current to the recording element 31. The recording element 31 is driven to cause film boiling of the ink to which thermal energy is applied inside the liquid chamber 30. As a result, ink is ejected from the ejection port 112 toward the recording medium, and recording is performed on the recording medium.

  In the above embodiment, the ink cartridge type in which the recording unit including the recording element substrate 103 and the ink storage container 102 are integrally formed is described, but the present invention is not limited to this. A system in which the recording unit and the ink storage container are detachable may be employed.

  The above-described recording apparatus is a so-called serial scan type recording apparatus that records an image with movement of the recording head in the main scanning direction and conveyance of the recording medium in the sub-scanning direction. However, the present invention is also applicable to a full-line type recording apparatus that uses a recording head that extends over the entire width of the recording medium.

  Further, although the recording head 101 of the present embodiment employs a system in which film boiling is generated by the recording element 31 as an electrothermal conversion element and foamed to eject ink droplets, the present invention is not limited to this. A recording head of a type that deforms the piezoelectric element and thereby discharges the liquid inside the recording head may be applied to the recording apparatus, or a recording head of another type may be applied to the recording apparatus of the present invention. good.

  Next, the configuration of the protective tape 120a will be described.

  FIG. 4 is a plan view of the periphery of the protective tape 120a in a state where the protective tape 120a is attached to the recording element substrate 103. FIG. The protective tape 120a includes a tag tape (tag member) 121 that does not have adhesive strength, a protective tape main body portion 130 that has adhesive strength on the surface to be attached, and a separator (non- And a covering portion covered with an adhesive member 13. The tag tape 121 is a portion that does not have adhesive force, and is a portion that a user grips with a finger when the protective tape 120 a is peeled off from the recording head 101.

  The protective tape 120a is affixed without the separator 13 being disposed around the discharge port 112 so as to exhibit adhesive strength around the discharge port 112. The protective tape 120a is formed to extend in only one direction from the portion where the ejection port 112 is formed, to the outside of the recording element substrate 103 in the direction intersecting the direction in which the ejection port array is arranged. A separator 13 is disposed on the outer side of the recording element substrate 103 in the protective tape 120a. Moreover, the adhesion part which the adhesive force is exhibited is formed in the part further outside the part in which the separator 13 is arrange | positioned in the protective tape 120a, without the separator 13 being arrange | positioned. Further, a tag tape 121 is attached to the outer side of the adhesive portion outside the portion where the separator 13 is disposed in the protective tape 120a. In the present embodiment, the tag tape 121 is affixed to the position of the end portion outside the recording element substrate 103 in the protective tape 120a in the direction intersecting the direction in which the ejection port arrays are arranged.

  FIG. 5 is a cross-sectional view schematically showing a cross section along the thickness direction of the protective tape 120a at a portion where the separator 13 is formed. The protective tape 120 a includes a base material 12 and is configured by applying the adhesive material 11 to one surface of the base material 12. Moreover, the separator 13 is arrange | positioned so that the adhesive material may be covered on the one surface of the base material 12, and the base material 12 and the adhesive material 11 are covered with the separator 13 in part by the protective tape 120a. That is, the separator 13 is disposed on the adhesive material 11 in a part of the protective tape 120a. The portion of the protective tape 120 a that adheres to the surface of the recording head 101 on which the ejection opening is formed is formed by applying the adhesive material 11 to the base material 12. Moreover, the separator 13 is arrange | positioned on the adhesive material 11 about the part which does not exhibit the adhesive force of the adhesive material 11 in a protective tape.

  In the protective tape 120a of this embodiment, a polyethylene terephthalate film having a thickness of 30 μm is used as the substrate 12. Further, 50 μm of the acrylic adhesive 11 is applied on the base 12 using a bar coater. After the adhesive material 11 is applied on the base material 12, the base material 12 and the adhesive material 11 are dried, and a 50 μm thick polyethylene terephthalate film is pasted thereon as the separator 13. The separator 13 is a film-like member and has flexibility.

  In the present embodiment, the protective tape 120a is affixed to the surface of the black recording element substrate on which the ejection ports are formed so as to cover the ejection ports of the recording head that ejects black ink. However, the protective tape of the present invention is not limited to this, and may be attached to a recording element substrate that discharges color ink.

  In order to prevent ink leakage from the ejection port 112 and evaporation of the ink from the ejection port 112 when the recording head 101 is distributed in the market, a protective tape 120a is attached to the portion where the ejection port 112 is formed. Attached. Since the protective tape 120a is affixed to the ejection port forming surface 160 so as to cover the ejection port 112 of the recording head 101 when the recording head 101 is in circulation, when the recording head 101 is in the market, Ink leakage from the ejection port 112 can be suppressed.

  In particular, the recording head 101 of this embodiment is an ink cartridge type in which a recording element substrate 103 that ejects ink and an ink storage container 102 are integrally configured. For this reason, when all the ink in the ink storage container 102 is used up, the ink storage container 102 is replaced with a new one together with the recording head 101 in the ink cartridge format. Therefore, in some cases, only the recording head 101 is distributed alone in the market, separately from the ink jet recording apparatus 1000. When only the recording head 101 is distributed in the market alone, it is necessary to protect the ink from impact during transportation and from drying. In particular, the recording element substrate 103 has a portion constituted by a thin wall surface, which may have low durability against impact. In addition, since the ejection opening having a small diameter is formed in the recording element substrate 103, the dust adheres to the portion where the ejection opening is formed or the ink adheres around the ejection opening. Target clogging is likely to occur. For this reason, the recording element substrate 103 is sensitive to impacts and dust adhesion. In order to protect the recording element substrate from these influences, when the recording head 101 is circulated in a state in which a film-like protective tape 120a is attached around the discharge port and a portion around the discharge port is protected There is.

  The protective tape main body 130 of the protective tape 120 a protects the discharge port by bringing the adhesive 11 into close contact with the surface of the recording element substrate 103 so as to close the discharge port of the recording element substrate 103. When replacing the recording head 101 with a new one, the user peels off the protective tape 120 a attached to the recording element substrate 103 of the recording head 101 and attaches it to the ink jet recording apparatus 1000. A protective tape may be affixed to the surface of the recording element substrate in which the recording element substrate and the ink storage container are separately formed, on which the ejection openings are formed.

  The manufacturing process of the protective tape 120a of this embodiment is demonstrated. The perspective view about the protective tape 120a of each manufacturing process is shown to Fig.6 (a)-(d). When manufacturing the protective tape 120 a, first, the adhesive material 11 is applied on the substrate 12. Then, the separator 13 is disposed on the adhesive material 11 so as to cover the entire base material 12 and the adhesive material 11. As a result, as shown in FIG. 6 (a), the adhesive material 11 is applied in layers on the substrate 12, and the separator 13 is disposed thereon, so that the protective tape 120a having three layers is formed. A tape member 140 is formed.

  Next, as shown in FIG. 6B, two layers of the base material 12 and the adhesive material 11 among the three layers constituting the tape member 140 are cut. Here, based on the length of each protective tape 120a when used, the base material 12 and the adhesive material 11 are cut so that the tape member 140 is formed to a predetermined length. The layer of the base material 12 and the adhesive material 11 is cut so as to cross along the width direction. At this time, since the separator 13 is not cut, the tape member 140 is connected by the separator 13. The tape member 140 is supplied to the next step in a state where the base material 12 is adhered to the separator 13 by the adhesive material 11.

  Next, as shown in FIG. 6C, the separator 13 is cut. Here, the separator 13 disposed at the position corresponding to the portion that exerts the adhesive force is removed while the separator 13 disposed at the position corresponding to the portion that does not exhibit the adhesive force in the protective tape 120a is left. Only the separator 13 of the three layers of the tape member is cut at this time. The cutting is performed so as to cross the separator 13 along the width direction of the separator 13.

  When the separator 13 is cut, as shown in FIG. 6D, the separator 13 is removed from the portion of the protective tape 120a that exerts the adhesive force. As a result, the tape member 140 is formed on the base material 12 and the adhesive material 11 in which the separator 13 is disposed only in a portion where the adhesive force by the adhesive material 11 is not desired to be exhibited.

  Tag tape 121 is affixed to the surface to which tape member 140 adheres, and protective tape 120a is formed. Thereby, the manufacturing process of the protective tape 120a is completed.

  When the manufacturing process of the protective tape 120a is completed, the protective tape 120a is attached to the periphery of the discharge port in the recording element substrate 103. By repeating the same procedure, the protective tape 120a can be continuously applied to the plurality of recording heads 101.

  In the above-described embodiment, the embodiment in which the separator 13 is formed over the entire width of the protective tape main body 130 in the protective tape 120a has been described. However, the present invention is not limited to this, and the protective tape 120a may be formed by leaving a portion along the width direction of the protective tape main body 130 where the separator 13 is not formed.

  FIG. 7 is a plan view of the protective tape 120b that is a part along the width direction of the protective tape main body 130 and in which a portion where the separator 13 is not formed is left. As shown in FIG. 7, since a portion where the separator 13 is not arranged is left in a part along the width direction, a plurality of protective tapes are continuously formed in a single peeling process of the separator 13 at the time of manufacturing. In contrast, the separator 13 can be peeled off. Since the separation process of the separator 13 at the time of manufacture can be collectively performed with respect to a some protective tape, the number of processes of the separation process of the separator 13 can be decreased. Thereby, the productivity of the protective tape 120b can be improved.

  Thus, in this embodiment, the separator 13 is arrange | positioned on the adhesive material 11 about the position which does not need to exhibit the adhesive force by the adhesive material 11 in the protective tape 120a, 120b. Therefore, the adhesive material 11 of the protective tapes 120a and 120b can be prevented from coming into direct contact with the recording head 101 in the recording head 101. The protective tape 120a, 120b and the recording head 101 are in contact with each other with the separator 13 sandwiched between the adhesive material 11 and the recording head 101 without being in direct contact with each other. Therefore, at that portion, the adhesive material 11 on the protective tapes 120a and 120b is suppressed from sticking to the recording head 101, and the strong adhesive force by the adhesive material 11 on the protective tapes 120a and 120b acts directly on the recording head 101. Can be suppressed. Accordingly, it is possible to prevent the protective tapes 120a and 120b from sticking to the recording head 101 at that portion.

  When the protective tapes 120a and 120b are peeled off from the recording head 101, the tag tape 121 is pulled upward. When the tag tape 121 is pulled upward, the portion of the protective tape 120a, 120b that is adhered to the recording head 101 without being disposed with the separator 13 is pulled upward. As a result, the protective tapes 120 a and 120 b are peeled from the recording head 101. Since the adhesive material 11 does not adhere to the recording head 101 at the portion where the separator 13 is disposed, the protective tapes 120a and 120b are easily pulled upward without using a large force. Therefore, the protective tapes 120a and 120b can be peeled from the recording head 101 with a relatively small force. That is, since the protective tape 120a, 120b is only partially adhered to the recording head 101, the force required to peel the protective tape 120a, 120b from the recording head 101 can be weakened. Thereby, it is possible to suppress the influence on the durability of the recording head 101 when the protective tapes 120a and 120b are peeled off. For example, when the protective tapes 120a and 120b are peeled off, it is possible to prevent the coating of the electric wiring tape 105 from being peeled off together with the protective tapes 120a and 120b due to an excessively strong adhesive force.

  Moreover, when adjusting the adhesive force by the adhesive material of the protective tapes 120a and 120b by preventing the adhesive force from the protective tapes 120a and 120b from being exhibited, the adhesive force is not formed on the protective tapes 120a and 120b. Adjustments can be made. Therefore, it is possible to prevent the protective tapes 120a and 120b from being bent and the creases associated therewith during distribution, and thereby the protective tapes 120a and 120b from being peeled off from the recording head 101. Accordingly, it is possible to suppress the impact on the discharge port forming surface 160 of the recording head 101 during distribution, and more reliably suppress ink leakage from the discharge port, and the recording with the protective tapes 120a and 120b attached thereto. The reliability of the head 101 can be further improved.

  Further, the adhesive force can be adjusted by the protective tapes 120a and 120b and the force required for peeling can be adjusted only by disposing the separator 13 in a part of the protective tapes 120a and 120b. Therefore, it is possible to easily manufacture the protective tapes 120a and 120b capable of adjusting the adhesive force and the peeling force.

  In this embodiment, an acrylic adhesive is used as the adhesive for the protective tape. However, the present invention is not limited to this, and other adhesive materials may be used as long as they have an adhesive strength that does not destroy the discharge port when the user peels off the protective tape 120a, 120b. Silicon-based or hot-melt adhesive materials may be used. Various materials can be used as the base material of the protective tape to be used as long as the purpose that the discharge port portion is not destroyed when the protective tapes 120a and 120b are peeled off can be achieved. Of course, the same applies to the separator, and various materials can be used as long as the purpose of covering the adhesive material of the protective tape and preventing the protective tape from sticking to the recording head portion other than the recording element substrate 103 can be achieved. is there.

  Moreover, in this embodiment, although the film-like polyethylene terephthalate film is used as the separator 13, this invention is not limited to this. A separator made of another material may be used as long as the adhesive force by the adhesive material can be prevented from being exhibited. The separator may be formed by applying a liquid material to the substrate 12.

  In the present embodiment, the separator 13 is attached to a region outside the recording element substrate 103 in the protective tapes 120a and 120b. However, the present invention is not limited to the above embodiment. The separator 13 may be affixed to a region inside the recording element substrate 103 in the protective tapes 120a and 120b.

  FIG. 8 is a plan view of the protective tape 120 c in a state where the separator 13 is attached to the inner region of the recording element substrate 103. FIG. 8 is a plan view showing the protective tape 120 c when the arrangement position of the separator 13 is expanded to the area inside the recording element substrate 103 in the embodiment shown in FIG. 4.

  FIG. 9 is a plan view of the protective tape 120d when the arrangement position of the separator 13 is expanded to the area inside the recording element substrate 103 in the embodiment shown in FIG.

  The recording element substrate 103 is formed with many liquid chambers and flow paths, and the strength of the recording element substrate 103 is often lower than the strength of other portions. Therefore, as shown in FIGS. 8 and 9, the separator 13 may be disposed so as to be located even on a portion on the recording element substrate 103. By disposing the separator 13 so as to extend to the area inside the recording element substrate 103 in the protective tapes 120c and 120d, the adhesive force of the protective tapes 120c and 120d on the recording element substrate 103 can be reduced. Thereby, the force required for peeling off the protective tapes 120c and 120d from the recording element substrate 103 can be reduced. Therefore, when the protective tapes 120c and 120d are peeled from the recording element substrate 103, it is possible to prevent an excessive load from being applied to the recording element substrate 103 due to an excessively strong adhesive force. That is, when the protective tapes 120 c and 120 d are peeled from the recording head 101, the force for peeling the protective tapes 120 c and 120 d on the recording element substrate 103 having a relatively low strength affects the durability of the recording element substrate 103. Giving up can be suppressed.

(Second Embodiment)
Next, the protective tape 120e which concerns on 2nd Embodiment of this invention is demonstrated. In addition, about the part comprised similarly to the said 1st Embodiment, the same code | symbol is attached | subjected in a figure, description is abbreviate | omitted, and only a different part is demonstrated.

  In FIG. 10, the top view of the protective tape 120e which concerns on 2nd Embodiment of this invention is shown. In the protective tape 120e of the second embodiment, the separator 13 is divided into a plurality along the X direction in FIG. 10 (arrangement direction of the ejection port arrays in the recording element substrate 103) and formed on the protective tape main body 130. . In the present embodiment, a plurality of separators 13 extending along a direction intersecting the direction in which the ejection port arrays are arranged on the recording element substrate 103 are formed on the protective tape main body 130. As described above, a plurality of separators 13 extending along the direction (Y direction) intersecting the direction in which the ejection port arrays are arranged on the recording element substrate 103 are formed in the protective tape main body 130 at intervals. A gap is formed between the separators 13. The plurality of gaps formed between the plurality of separators 13 extending along the direction intersecting the direction in which the discharge port arrays are arranged are formed to extend along the direction intersecting the direction in which the discharge port arrays are arranged. ing. Therefore, in the protective tape main body part 130 in the protective tape 120, the part which exhibits the adhesive force by the adhesive material 11 is formed so that it may extend along the direction which cross | intersects the direction where the discharge port row | line | column was arranged.

  In addition, a plurality of portions extending along the direction intersecting the direction in which the discharge port arrays are arranged and exhibiting the adhesive force by the adhesive material 11 are formed along the direction in which the discharge port arrays are arranged. Therefore, the part which does not exhibit the adhesive force by the adhesive material 11 by forming the separator 13 is sandwiched on both sides along the arrangement direction of the discharge port arrays by the portion which exhibits the adhesive force by the adhesive material 11. By forming the separator 13 partially along the arrangement direction of the discharge port array and forming a portion that does not exert the adhesive force, the adhesive force by the protective tape 120e can be weakened as a whole. At the same time, since the adhesive force is continuously exerted along the direction intersecting the arrangement direction of the discharge port arrays, the protective tape 120e is stably attached to the discharge port forming surface 160 of the recording head 101. Therefore, it is possible to prevent the protective tape 120e from being peeled off from the recording head 101 at the stage of distribution of the recording head 101.

  In particular, when there is a large step between the recording element substrate 103 and the electric wiring tape 105 or when the surface of the electric wiring tape 105 is wavy, there is a relatively large gap between the protective tape 120e and the recording head 101. May occur. In that case, a stress that causes deformation may act on the protective tape 120e.

  When such stress acts on the protective tape 120e, the protective tape 120e may be peeled off from the recording element substrate 103. Even in such a case, in the present embodiment, since the separator 13 is divided into a plurality along the arrangement direction of the discharge port arrays, it is possible to suppress the stress from spreading over the entire protective tape 120e.

(Third embodiment)
Next, a protective tape 120f according to a third embodiment of the present invention will be described. In addition, about the part comprised similarly to the said 1st Embodiment and 2nd Embodiment, the same code | symbol is attached | subjected in a figure, description is abbreviate | omitted, and only a different part is demonstrated.

  In the protective tape 120f of the third embodiment, the separator 13 is further finely divided. FIG. 11 is a plan view of the protective tape 120f according to the third embodiment.

  In the protective tape 120f shown in FIG. 11, the separator 13 is not only divided into a plurality along the arrangement direction of the discharge port arrays (X direction in FIG. 11), but also in the direction intersecting the arrangement direction of the discharge port arrays. It is divided into a plurality along (Y direction in FIG. 11). Therefore, a plurality of separators 13 are formed on the protective tape main body 130 at intervals in the direction in which the ejection port arrays are arranged in the recording element substrate 103, but also intersect the direction in which the ejection port arrays are arranged. A plurality are arranged at intervals in the direction (second direction). Accordingly, not only a gap is formed between the separators 13 adjacent in the direction in which the discharge port arrays are arranged, but also between the separators 13 adjacent in the direction intersecting with the direction in which the discharge port arrays are arranged. A gap is formed.

  As described above, since the gap is formed between the separators 13 adjacent to each other in the direction in which the discharge port arrays are arranged and the direction intersecting the direction in which the discharge port arrays are arranged, the separators divided in both directions are formed. A plurality of 13 are formed. Therefore, the part that exerts the adhesive force by the adhesive material 11 extends along both the direction in which the discharge port arrays are arranged and the direction that intersects the direction in which the discharge port arrays are arranged. Moreover, the part which exhibits the adhesive force by the adhesive material 11 is formed in multiple numbers along both the direction where the discharge port row is arranged and the direction which intersects the direction where the discharge port row is arranged.

  Therefore, when the separator 13 is formed, the portion that does not exert the adhesive force by the adhesive material 11 intersects the arrangement direction of the discharge port array and the arrangement direction of the discharge port row by the portion that exhibits the adhesive force by the adhesive material 11. Both sides are sandwiched in both directions. Accordingly, the adhesive force is continuously exerted along both the arrangement direction of the ejection port arrays and the direction intersecting the arrangement direction of the ejection port arrays, so that the protective tape 120f can form the ejection ports in the recording head 101 more stably. Affixed to the surface 160. Therefore, it is possible to further reliably prevent the protective tape 120f from peeling from the recording head 101 at the stage of distribution of the recording head 101.

  Further, by partially forming the separator 13, the adhesive force of the protective tape 120f to the recording head 101 can be weakened as a whole. Thereby, the adhesive force of each part in the protective tape 120f can be adjusted.

(Other embodiments)
In the second embodiment, the protective tape 120e in which a plurality of the separators 13 are arranged in the arrangement direction of the discharge port arrays has been described. In the third embodiment, the protective tape 120f in which a plurality of the separators 13 are arranged in the direction intersecting the arrangement direction of the discharge port arrays and the arrangement direction of the discharge port arrays has been described. However, the present invention is not limited to this, and a plurality of separators 13 are arranged in a direction (second direction) intersecting the arrangement direction of the discharge port arrays as in the protective tape 120g shown in FIG. There may be.

  Further, when a plurality of separators 13 such as the protective tape 120e shown in FIG. 10 are arranged in the arrangement direction of the ejection port arrays, a part of the separators 13 may be arranged inside the recording element substrate 103. Similarly, when a plurality of separators 13 such as the protective tape 120f shown in FIG. 11 are arranged in the direction in which the discharge port arrays are arranged and in a direction intersecting with the arrangement direction, a part of the separators 13 is formed on the recording element substrate. It may be arranged inside 103. In addition, when a plurality of separators 13 as shown in FIG. 12 are arranged in a direction crossing the arrangement direction of the ejection port arrays, a part of the separators 13 may be arranged inside the recording element substrate 103. By disposing the separator 13 in this manner, it is possible to prevent an excessive load from being applied to the recording element substrate 103 when the protective tape is peeled from the recording head 101.

  Moreover, the separator 13 may be arrange | positioned in positions other than the position demonstrated above. If the adhesive force can be adjusted so that the adhesive force by the protective tape does not become excessively strong, the separator 13 may be arranged in another form.

  Further, in this specification, “recording” is used not only for forming significant information such as characters and figures but also regardless of significance.
