Description

  The present invention relates to a protective member for a liquid jet recording head capable of protecting the liquid jet port surface of a liquid jet recording head having a liquid jet port surface, a liquid jet recording head having the protective member, and a liquid jet recording head therefor The present invention relates to a liquid jet recording apparatus provided.

  In a liquid jet recording apparatus, a liquid jet recording head that can be attached to and detached from a recording system such as a carriage that scans toward a recording medium has been put into practical use. The liquid jet recording head may be individually sealed in a packaging container in consideration of handling as a single unit for the convenience of transactions in productivity or serviceability. At that time, the liquid discharge port surface and the like in the liquid jet recording head to be packaged are generally protected in order to prevent damage or contamination. The protection includes a configuration in which an adhesive tape or the like is attached to and covered with the liquid discharge port surface, and a configuration in which the protective member is engaged and held around the liquid discharge port surface of the liquid jet recording head to surround the liquid discharge port surface. Etc.

  Hereinafter, an example of a conventional configuration disclosed in Patent Document 1 in which the protective member surrounds the liquid discharge port surface of the liquid jet recording head will be described.

  20 is an external side view showing the liquid jet recording head and the protection member, and FIGS. 21 and 22 are cross-sectional views showing the liquid jet recording head and the protection member. FIG. 22 is a diagram showing a state in the middle of removing the protective member, and FIG. 22 is a diagram showing a state in which the protective member is disengaged.

In the figure, the operator engages the clue unit 104 and moves the first wall surface 101 in a direction away from the liquid jet recording head 121, thereby disengaging the first engagement unit 102. Subsequently, the protection member 122 is rotated so that the first engagement portion 102 moves downward (in the direction of arrow G) with the engagement position of the second engagement portion 103 as a fulcrum, and the uppermost portion of the clue portion 104. When 104a moves to the vicinity of the region below the bottom 121a of the liquid jet recording head 121, the engagement of the second engagement portion 103 becomes shallow, the engagement of the second engagement portion is released, and the protective member 122 is removed from the liquid jet recording head 121.

  However, when the liquid jet recording head packaged as described above is attached to the liquid jet recording apparatus, there are the following problems.

  First, the problem of the configuration in which an adhesive tape or the like is affixed to the liquid ejection port surface will be described. The adhesive tape affixed to the ejection port surface of the liquid jet recording head is peeled off from the liquid ejection port surface in advance. However, the adhesive component of the adhesive tape may remain on the liquid discharge port surface of the liquid jet recording head depending on the storage period, the storage period, and in such a case, some of the plurality of liquid discharge ports The liquid ejection operation may not be performed normally due to clogging with the adhesive component. For this reason, there are many functions required for the adhesive performance of adhesive tapes, and this has led to an increase in development load and an increase in the unit cost of adhesive tape parts.

  Next, the problem of the configuration in which the protective member surrounds the liquid discharge port surface will be described.

  In recent years, the liquid jet recording apparatus 121 has been remarkably improved in the performance of high-quality and high-speed printing, and the printing speed will be further increased in the future. Increasing the length by increasing the array length of the discharge ports is an effective means for high-speed printing. However, when the liquid jet recording head 121 is elongated, the relative distance between the first engaging portion 102 and the second engaging portion 103 facing each other in the protective member 122 increases, and the engaging position of the second engaging portion 103 is increased. The radius of rotation of the first engaging portion 102 with fulcrum as the fulcrum is increased. Therefore, when removing the protection member 122 from the liquid jet recording head 121, the rotation angle of the protection member 122 until the engagement of the second engagement portion 103 is increased. As a result, the operator cannot easily remove the protective member 122 or troublesome removal work, and the operator may be confused.

  In addition, as described above, when the removal work of the protection member 122 is troublesome or the method of removal becomes unclear, the operator may apply an excessive load toward the liquid jet recording head 121 or the protection member 122 in a direction different from the desired direction. There is a risk that the protective member 122 may be twisted or deformed due to the action such as adding, and the liquid jet recording head 121 may be damaged or soiled.

  In particular, in the case of the protective member 122 having the liquid storage unit 105 that collects the liquid leaking from the liquid ejection unit of the liquid jet recording head 121, the liquid storage unit 105 is in the liquid jet recording head 121 in the engaged state of the protective member. Therefore, if an excessive load is applied to the protective member 122, the liquid storage unit 105 may be brought close to the liquid discharge unit of the liquid jet recording head 121. It was done.

  In addition, the liquid jet recording head sealed in the packaging container is exposed to a high temperature and low humidity environment, for example, at a temperature of 70 ° C. and a humidity of 0% for a long time, or packaging due to variations in mass production. When a completely sealed state cannot be realized due to a slight gap in an incompletely sealed part of the container, or when a completely sealed state cannot be achieved due to a slight pinhole in the sealing part of the packaging container material itself, etc. Thus, the humidity in the packaging container decreases, the liquid such as ink filled in the liquid jet recording head (eg, storage-only ink) gradually evaporates and the liquid near the discharge port solidifies, and the recording ink is discharged. There is a possibility that a thickened material such as ink disappears or remains in the vicinity of the ejection port, and the ejected liquid droplet does not land at an accurate position.

  In view of the above problems, the present invention is a protection member for a liquid jet recording head capable of protecting the liquid ejection port surface of a liquid jet recording head having a liquid ejection portion, and a liquid jet recording head having the protection member And a recording apparatus provided with the liquid jet recording head, the liquid ejection port surface of the liquid jet recording head being maintained in a clean state without being affected by the storage state and storage period, and Protective member that can be easily removed from the liquid jet recording head even if the discharge port is a liquid jet recording head having an elongated discharge port, and a liquid jet recording head having the protective member An object of the present invention is to provide a recording apparatus provided with the liquid jet recording head.

  It is another object of the present invention to provide a storage method for a liquid jet recording head that does not deteriorate the recording performance while the sealed liquid jet recording head is stored in a packaging container.

  In order to achieve the above object, the present invention takes the following measures.

The first means is engaged with an engaged portion provided around a liquid discharge portion of a liquid jet recording head that performs recording by ejecting liquid droplets onto a recording medium, and is applied to the liquid jet recording head. An engaging portion to be held;

In the liquid jet recording head protecting member, wherein the wall surface surrounds and protects the liquid discharge portion of the liquid jet recording head, the third to fourth wall surfaces are in the vicinity of the first to second support portions and the first to second support portions. A protective member for a liquid jet recording head, a liquid jet recording head having the protective member, or the liquid jet recording head, characterized in that a guide portion that protrudes and extends beyond the second support portion is provided. Recording device .

  A second means is a plurality of the first means, wherein the liquid leaking from the liquid discharge portion of the liquid jet recording head is formed to face the discharge port surface of the liquid discharge portion with a predetermined gap. A liquid jet recording head having a liquid storage section for storing in a partition wall having a predetermined height divided into small chambers of the liquid jet recording head or the liquid jet recording head having the protective member Is a recording apparatus.

  The third means is the first to second means described above, wherein the guide portion has a higher relative height to the first to second support portions as it is separated from the first to second support. A liquid jet recording head having the protective member, a liquid jet recording head having the protecting member, or a recording apparatus provided with the liquid jet recording head.

  The fourth means is characterized in that, in the first to third means described above, the extending direction of the guide portion of the third to fourth wall surfaces and the extending direction of the receiving portion of the liquid jet recording head are obliquely intersected. And a recording apparatus provided with the liquid jet recording head having the protective member or the liquid jet recording head.

  A fifth means is the first to fourth means described above, wherein the protection member is engaged with and held by the liquid jet recording head in the state where the protection member is engaged with the liquid jet recording head. A protective member for a liquid jet recording head or a liquid jet recording head having the protective member, wherein the guide portion and a restricting portion that contacts or approaches in a direction perpendicular to the extending direction of the guide portion are formed, or A recording apparatus includes a liquid jet recording head.

  A sixth means is a member for protecting a liquid jet recording head according to any one of the first to fifth means, wherein the guide portion forms a smooth surface by a shape such as a slope, an arc, or a curve. Alternatively, the present invention is a liquid jet recording head having the protective member or a recording apparatus provided with the liquid jet recording head.

  The seventh means is a rib, bead, block, etc., in the first to seventh means described above, so that the bottom surface intersecting the first to fourth wall surfaces is substantially parallel to the extending direction of the guide portion. A liquid jet recording head having a protective member for a liquid jet recording head, or a liquid jet recording head having the protecting member, or a recording apparatus provided with the liquid jet recording head.

  The eighth means has a packaging container for sealing the liquid jet recording head described in the first to sixth means, and is provided on the bottom surface of the protective member and is an ejection port of the liquid jet recording head. A groove-like accommodation room in which a liquid-absorbable absorber is accommodated on the surface side is arranged so as to be substantially parallel to the extending direction of the guide portion, and an outer wall covering the circumference of the accommodation room is used for the protection A liquid jet recording head having a protective member for a liquid jet recording head, or a liquid jet recording head having the protection member, or a recording apparatus provided with the liquid jet recording head, which protrudes from a bottom surface of the member.

  According to the protection member for the liquid jet recording head, the liquid jet recording head including the protection member, and the recording apparatus including the protection member according to the present invention, the operator places a hand on the clue portion of the protection member and first By rotating the protection member downward with the engagement position of the second engagement portion as a fulcrum while releasing the engagement of the engagement portion, the guide portion of the protection member is driven by the turning force of the protection member. Since the contact portion slides in contact with the receiving portion on the lower surface of the liquid jet recording head, the guide portion further promotes the rotation of the protective member, and the operator does not have to be aware of rotating the protective member himself. It moves easily until it reaches the state where the engagement of the second engagement portion is released, and the operator can easily remove the protective member without hesitation.

  Further, in a state where the protective member is engaged with and held by the liquid jet recording head, a restriction portion that is in contact with or close to the guide portion of the protective member is provided on the liquid jet recording head. When the rotation angle is small, the guide portion and the restricting portion are close to each other, so that the movement of the protective member in the lateral direction (the opposite direction of the third wall surface and the fourth wall surface) is restricted, and the protective member is It does not shake in the direction, and is guided to turn straight.

  In addition, the configuration in which the bottom surface protrusion is disposed on the bottom surface side of the protective member and the guide portions H2021c and H2022c are formed in a protruding shape, and the region other than the first wall surface that is elastically deformed has high rigidity. Even when a force is applied in a direction other than the direction, the protective member can be guided to the disengagement stage of the second engaging portion without being twisted. Therefore, the operation of removing the protection member does not damage or damage the liquid jet recording head or the protection member. Further, the protective member can be easily detached from the liquid jet recording head by a small angle of rotation.

  In addition, by causing the extending direction of the guide portion of the protective member and the extending direction of the receiving portion of the liquid jet recording head to intersect obliquely, the rotation angle of the protective member increases at the contact position between the guide portion and the receiving portion. Therefore, since it approaches the 2nd engagement part (rotation center), it becomes possible to make the protrusion height of a guide member small, and a protection member can be made small.

  Further, since the guide portion and the receiving portion slide obliquely crossing each other, the protective member is guided in the lateral direction orthogonal to the rotation direction and the protective member is shaken in the lateral direction. It will help to release the engagement of the second engaging portion which has been in a shallow engagement state due to the rotation of the member. Therefore, the protective member can be easily removed from the liquid jet recording head even if it moves at a small rotation angle.

  When the rotation of the protective member proceeds until the guide portion of the protective member and the receiving portion of the liquid jet recording head come into contact with each other, the extending direction of the guide portion and the extending direction of the receiving portion obliquely intersect with each other. As a result, a force that is guided laterally acts on the protective member, and the protective member is shaken laterally. On the other hand, since the rotation of the protective member has already progressed and the second engagement portion is in a shallow engagement state, the above-described shaking facilitates the disengagement of the second engagement portion. Therefore, even if the protective member is not rotated until the engagement depth of the second engaging portion becomes sufficiently shallow, the protective member can be easily detached from the liquid jet recording head by movement with a small rotation angle.

  Further, in a state in which the protection member is engaged and held by the liquid jet recording head, the liquid storage portion that collects the liquid leaking from the liquid discharge portion of the liquid jet recording head is provided near the liquid discharge portion as the protection portion. With the arrangement, the liquid discharge port surface of the liquid jet recording head can be maintained in a clean state without being affected by the storage state and storage period of the liquid jet recording head. Further, even if an excessive load is applied during the rotation of the protective member, the liquid ejection unit and the liquid storage unit do not come into contact with each other due to the contact between the guide member and the receiving unit. Damage and fouling can be avoided.

  In addition, a protective chamber is provided in the protective member to store the liquid-containing absorber, thereby preventing the humidity in the packaging container from decreasing even in a high-temperature and low-humidity environment, and filling the liquid jet recording head. The liquid (for example, storage-specific ink) gradually evaporates and the thickened ink or the like is solidified near the ejection port, so that the recording ink can no longer be ejected, or the thickened ink remains near the ejection port. It is possible to avoid the occurrence of problems such as drops not landing at normal positions.

  Note that the above-described effects in the present invention are particularly effective in the elongated liquid jet recording head.

  Support portions H2021a, H2021b, H2022a, and H2022b are formed on the upper surfaces of the third wall surface H2021 and the fourth wall surface H2022, and contact the receiving portions H1501, H1502, H1503, and H1504 formed on the lower surface of the flow path forming member H1500. It comes to be touched. That is, the support portion H2021a of the third wall surface H2021 is supported by the receiving portion H1501, the support portion H2021b of the third wall surface H2021 is supported by the receiving portion H1503, the support portion H2022a of the fourth wall surface H2022 is supported by the receiving portion H1502, and the fourth wall surface H2022 is supported. The first claws H2001a and H2001b and the second claws H2002a and H2002b are engaged with each other by bringing the portion H2022b into contact with the receiving portion H1504.

  Therefore, even when the protective member H2000 is engaged with and held by the liquid jet recording head H1001, the protective port H2003 is protected even if the discharge port surface cover portion H2003 is pressed in the direction approaching the recording element substrate H1100 of the liquid jet recording head H1001. Since the movement is limited by the contact between the support portion of the member and the receiving portion of the flow path forming member H1500, the engagement between the first claws H2001a and H2001b and the second claws H2002a and H2002b cannot be easily released.

  Further, guide portions H2021c and H2022c are provided on the upper surfaces of the third wall surface H2021 and the fourth wall surface H2022. The guide portions H2021c and H2022c protrude in a direction closer to the recording element substrate H1100 than the support portions H2021a, H2021b, H2022a, and H2022b, and are formed in a smooth curved shape.

  In a state where the protective member H2000 is engaged and held with the liquid jet recording head H1001, the inner side surface H2021d of the third wall surface H2021 and the inner side surface H2022d of the fourth wall surface H2022 are close to the protrusions H1200a and H1200b of the first plate H1200. To be arranged.

  A plurality of back protrusions H2001p are formed in parallel with each other at a predetermined interval on the surface of the first wall surface H2001 opposite to the arrangement surface of the first claws H2001a and H2001b.

  The discharge port surface cover portion H2003 is provided with bottom surface projections H2003a and H2003b that protrude toward the bottom surface in a direction substantially parallel to the extending direction of the guide portions H2021c and H2022c, and the guide portions H2021c and H2022c extend. Increased direction rigidity. Further, an anti-slip H2003e integrally formed in a concavo-convex shape is provided on the external surface of the discharge port surface cover portion H2003.

  The above-described bottom protrusions H2003a and H2003b and the back protrusion H2001p prevent the liquid jet recording head H1001 to which the protection member H2000 is attached from being erroneously attached in the carriage M4001, and the protection member H2000. Is inserted into the carriage M4001, the bottom projections H2003a, H2003b and the back projection H2001p interfere with the outer peripheral edge of the carriage M4001, and as a result, are mounted in the carriage M4001. It becomes impossible to do.

  On the other hand, a liquid receiving part H2004 as a liquid storage part is provided at substantially the center of a flat portion sandwiched between the first wall surface H2001, the second wall surface H2002, the third wall surface H2021, and the fourth wall surface H2022 in the discharge port surface cover portion H2003. Protrusively formed. The outer wall of the liquid receiving part H2004 is formed in a substantially rectangular shape by a wall having a predetermined thickness raised toward the recording element substrate H1100 in the discharge port surface cover part H2003. As shown in FIG. 7, the inner side of the liquid receiving part H2004 is divided into a plurality of small rooms by lattice-like ribs H2004a having the same height as the outer wall. The size of each small room is, for example, about 0.5 to 1.0 (mm) × about 0.5 to 2.0 (mm). The size of each small room may be set as appropriate as long as it can hold ink or the like.

  Further, when the protective member H2000 is mounted, as shown in FIG. 9, the contact between the support portions H2021a, H2021b, H2022a, H2022b and the receiving portions H1501, H1502, H1503, H1504 of the flow path forming member H1500. A predetermined gap CL of, for example, about 0.5 to 1.0 (mm) is formed between the tip of the rib H2004a and the recording element substrate H1100.

  Therefore, for example, as shown in FIG. 8, when the liquid receiving portion is not provided in the discharge port surface cover portion H2003 ′ of the protection member H2000 ′, the ink IK leaked from the recording element substrate H1100 for some reason is Then, the ink is accumulated in the discharge port surface cover portion H2003 ′ to form the ink reservoir IK ′. As a result, the ink in the ink reservoir IK ′ may flow into the terminal cover portion H2001 ′.

  On the other hand, in the protective member H2000, the ink IK leaked from the recording element substrate H1100 for some reason is relatively contained in each small chamber in the liquid receiving portion H2004 of the discharge port surface cover portion H2003 as shown in FIG. There is no possibility that the ink is stored as a small amount of ink IK ′ and flows out by the capillary force.

  For example, as shown in FIG. 10, the liquid jet recording head cartridge H1000 mounted with such a protective member H2000 is maintained in the position where the recording element substrate H1100 is at the lowest position, and is individually placed in the packaging container H2010. It is transported in a packaged state.

[Protection member removal operation]
11 to 14 are schematic views for explaining the removing operation of the protective member.

  From the state where the protective member H2000 as shown in FIG. 11 is engaged and held by the liquid jet recording head H1001, the operator hands on the operation portion H2001e of the protective member H2000 against the elastic force of the first wall surface H2001. After releasing the engagement of the first claws H2001a and H2001b by pressing in the direction of the arrow A, the protective member H2000 is rotated in the direction of the arrow B with the engaging portion of the second claws H2002a and H2002b as a fulcrum. Let

  At a stage where the rotation angle is small, such as immediately after the start of the removal operation of the protective member H2000, the inner surface H2021d of the third wall surface H2021 and the inner surface H2022d of the fourth wall surface H2022 are close to the protrusions H1200a and H1200b of the first plate H1200. When the protective member H2000 is moved in the lateral direction (opposite direction of the third wall surface H2021 and the fourth wall surface H2022), the inner surface H2021d of the third wall surface H2021 and the protrusion H1200a or the inner surface of the fourth wall surface H2022 Since H2022d and the protrusion H1200b interfere with each other, the protective member H2000 does not shake in the lateral direction and rotates straight in the arrow B direction.

  The means for restricting the lateral movement of the protective member is not limited to the protrusions H1200a and H1200b of the first plate H1200 as described above, and protrusions and the like are formed from the flow path forming member H1500 and the flow path member H1600. The same effect can be obtained even with the structure to be formed.

  By arranging the bottom projections H2003a and H2003b on the bottom side of the discharge port cover H2003 and by projecting the guides H2021c and H2022c, regions other than the first wall H2001 that is elastically deformed have high rigidity. Therefore, even if the operator applies a force in a direction other than the desired direction, the protective member H2000 can be guided to the disengagement stage of the second claws H2002a and H2002b without being twisted. Therefore, the operation of removing the protective member H2000 does not damage or damage the liquid jet recording head or the protective member. Further, the protective member H2000 can be easily detached from the liquid jet recording head H1001 by a small angle of rotation.

  Thus, the protective member H2000 is vigorously rotated and pushed forward (in the direction of arrow C) by a series of operations such as rotating the protective member H2000 while releasing the engagement of the first claws H2001a and H2001b. It is. When the protective member H2000 is pushed forward, the guide portions H2021c and H2022c of the protective member H2000 come into contact with the receiving portions H1501 and H1502 of the liquid jet recording head H1001, and the inner ridgelines H1501a and H1502a of the receiving portions H1501 and H1502 are obtained. And the curved surfaces of the guide portions H2021c and H2022c slide, and this sliding facilitates the rotation of the protective member H2000 in the direction of the arrow B, and the operator himself rotates the protective member H2000. The protective member H2000 continues to rotate without being consciously operated. And it will reach | attain easily until it will be in the state where engagement of 2nd nail | claws H2002a and H2002b becomes shallow, and the protection member H2000 can be easily removed from the liquid jet recording head H1001.

  Further, as described above, when the rotation of the protection member H2000 proceeds until the guide portions H2021c and H2022c of the protection member H2000 come into contact with the receiving portions H1501 and H1502 of the liquid jet recording head H1001 (see FIG. 12). Since the extending direction of the portions H2021c and H2022c and the extending direction of the receiving portions H1501 and H1502 obliquely intersect each other (the inner ridgelines H1501a and H1502a of the receiving portions H1501 and H1502 and the curved ridgelines of the guide portions H2021c and H2022c intersect each other obliquely. ), A force that induces the protection member H2000 in the lateral direction (opposite direction of the third wall surface H2021 and the fourth wall surface H2022) acts, and the protection member H2000 is shaken in the lateral direction. On the other hand, since the rotation of the protective member H2000 has already progressed and the engagement of the second claws H2002a and H2002b has become shallow, the disengagement of the second claws H2002a and H2002b is released by the shaking described above. Will be encouraged. Therefore, the engagement of the second claws H2002a and H2002b is released by the movement of the protective member H2000 with a small rotation angle, and the protective member H2000 can be easily detached from the liquid jet recording head H1001.

  Further, since the contact position between the guide portions H2021c and H2022c and the receiving portions H1501 and H1502 approaches the engaging portion (rotation center) of the second claw as the rotation angle of the protective member H2000 increases, the guide portions H2021c and H2022c It is possible to reduce the protruding height of the protective member, and the protective member can be reduced.

  As described above, the operator places a hand on the operation portion H2001e of the protective member H2000 and rotates the protective member H2000 in the arrow B direction while releasing the engagement of the first claws H2001a and H2001b. The protection member rotates straightly in the direction of arrow B, and the guide portions H2021c and H2022c and the receiving portions H1501 and H1502 slide by the force of rotation to promote the rotation of the protection member. Further, from this stage, the protection member H2000 is swayed in the lateral direction to prompt disengagement of the second claws H2002a and H2002b, and the protection member H2000 can be easily removed. That is, when the operator intuitively touches the operation unit H2001e, the protective member H2000 rotates and reaches the second claw H2002a, H2002b disengagement stage with a small rotation angle by the rotational force. it can.

  Therefore, the operator can easily remove the protective member H2000 without taking any action such as losing operation or applying an excessive load.

  Even if an excessive load is applied during the rotation operation of the protective member H2000, the recording liquid element substrate of the liquid receiving part H2004 and the liquid jet recording head H1001 is brought into contact with the guide parts H2021c, H2022c and the receiving parts H1501, H1502. The H1100 does not approach, and damage and contamination of the liquid ejection unit can be avoided.

(Example 2)
FIG. 19 is an external perspective view showing a protective member according to Embodiment 2 of the present invention.

  The second embodiment of the present invention will be described below with the same reference numerals assigned to the same parts as the first embodiment, based on FIG.

  H3001 and H3002 are liquid absorbers, and the liquid absorbers H3001 and H3002 are made of a foam molding material, a fiber lump, paper, or the like.

  Storage chambers H2003c and H2003d are disposed in the vicinity of the liquid receiving portion H2004 of the discharge port surface cover portion H2003, and the liquid absorbers H3001 and H3002 are compressed and inserted into the storage chambers H2003c and H2003d. As described above, since the liquid absorbers H3001 and H3002 are held by the protective member H2000 by compression and insertion, they do not come off even if they are subjected to vibration, drop, etc. that may occur during physical distribution.

  By injecting liquids such as distilled water and distribution dedicated ink into the absorbers H3001 and H3002, the humidity inside the packaging container H2010 is maintained. Accordingly, it is possible to prevent the humidity inside the packaging container from decreasing even under a high temperature and low humidity environment, and to suppress the thickened ink and the like from stagnating near the discharge port due to evaporation or the like.

  Further, since the bottom projection H2003b also serves as an outer wall covering the accommodation room H2003d, the bottom projections H2003a and H2003b provide the mechanical strength of the accommodation rooms H2003c and H2003d and the protective member H2000 that accommodate the absorbers H3001 and H3002. It comes to have two functions, such as improving, and unlike the configuration in which each function is individually provided, an increase in the size of the protective member H2000 can be suppressed.
