記録ヘッドと傾斜部材の間に溝があると、記録ヘッドが払拭により掻き集めたインクがその溝に入ることにより、記録ヘッドに残るインクを少なくすることができる。しかし、その溝にワイピング部材が引っかかると、インクが周囲に飛散してしまう、という課題がある。   If there is a groove between the recording head and the inclined member, the ink collected by wiping by the recording head enters the groove, so that the ink remaining in the recording head can be reduced. However, when the wiping member is caught in the groove, there is a problem that ink is scattered around.

このような課題は、インクを噴射する記録ヘッドをワイピング部材で払拭する場合に限らず、液体を噴射する液体噴射ヘッドを払拭部材で払拭する液体噴射装置においては、概ね共通したものとなっている。   Such a problem is not limited to the case of wiping the recording head that ejects ink with the wiping member, but is generally common in the liquid ejecting apparatus that wipes the liquid ejecting head that ejects the liquid with the wiping member. .

本発明は、こうした実情に鑑みてなされたものであり、その目的は、払拭に伴う液体の飛散を抑制することができる液体噴射装置を提供することにある。   The present invention has been made in view of such circumstances, and an object thereof is to provide a liquid ejecting apparatus capable of suppressing scattering of liquid accompanying wiping.

以下、液体噴射装置の実施形態について、図を参照して説明する。液体噴射装置は、例えば、用紙などの媒体に液体の一例であるインクを噴射することによって記録（印刷）を行うインクジェット式のプリンターである。   Hereinafter, an embodiment of a liquid ejecting apparatus will be described with reference to the drawings. The liquid ejecting apparatus is an ink jet printer that performs recording (printing) by ejecting ink, which is an example of liquid, on a medium such as paper.

図１に示すように、液体噴射装置１１は、液体を噴射するノズル１２を有する液体噴射ヘッド１３と、液体噴射ヘッド１３を保持する保持部１４と、液体収容体１５に収容された液体を液体噴射ヘッド１３に向けて供給する供給流路１６と、を備える。本実施形態の液体噴射ヘッド１３は、印刷範囲が媒体Ｓの幅全体に亘るラインヘッドであり、液体噴射ヘッド１３が液体を噴射する位置を記録位置という。   As illustrated in FIG. 1, the liquid ejecting apparatus 11 includes a liquid ejecting head 13 having a nozzle 12 that ejects liquid, a holding unit 14 that holds the liquid ejecting head 13, and liquid stored in a liquid container 15. And a supply flow path 16 for supplying the ejection head 13. The liquid ejecting head 13 of the present embodiment is a line head whose printing range extends over the entire width of the medium S, and a position where the liquid ejecting head 13 ejects liquid is referred to as a recording position.

液体噴射装置１１は、印刷前の媒体Ｓを複数収容可能な収容カセット１９と、印刷済みの媒体Ｓを保持する保持トレイ２０と、液体噴射ヘッド１３のメンテナンスを行うメンテナンス装置２１と、各構成要素を制御する制御部１００と、を備える。   The liquid ejecting apparatus 11 includes a storage cassette 19 that can store a plurality of media S before printing, a holding tray 20 that holds the printed medium S, a maintenance device 21 that performs maintenance of the liquid ejecting head 13, and each component. The control part 100 which controls this is provided.

液体噴射装置１１は、収容カセット１９から保持トレイ２０に向けて湾曲しつつ延びる媒体Ｓの搬送経路上に配置された複数の搬送ローラー１７と、記録位置において媒体Ｓを支持する搬送ベルト１８と、を備える。搬送ベルト１８は、メンテナンス装置２１が液体噴射ヘッド１３のメンテナンスを行うときには、図１に実線で示す支持位置から、図１に二点鎖線で示す退避位置に退避する。   The liquid ejecting apparatus 11 includes a plurality of transport rollers 17 disposed on a transport path of the medium S that extends while curving from the storage cassette 19 toward the holding tray 20, a transport belt 18 that supports the medium S at a recording position, Is provided. When the maintenance device 21 performs maintenance of the liquid ejecting head 13, the transport belt 18 is retracted from the support position indicated by the solid line in FIG. 1 to the retract position indicated by the two-dot chain line in FIG.

支持位置にある搬送ベルト１８上において媒体Ｓが進む方向を搬送方向Ｙとし、搬送ベルト１８に支持された媒体Ｓに対して液体噴射ヘッド１３が液体を噴射する方向を噴射方向Ｚとする。また、図１で紙面と直交する方向を媒体Ｓの幅方向Ｘとする。   A direction in which the medium S travels on the transport belt 18 at the support position is defined as a transport direction Y, and a direction in which the liquid ejecting head 13 ejects liquid onto the medium S supported by the transport belt 18 is defined as an ejection direction Z. In FIG. 1, the direction orthogonal to the paper surface is defined as the width direction X of the medium S.

メンテナンス装置２１は、キャップ２２と、キャップ２２に接続された廃液流路２３と、廃液流路２３の途中に設けられた吸引ポンプ２４と、キャップ２２を移動させる移動機構２５と、液体噴射ヘッド１３のワイピングを行うワイピング装置４０と、を備える。そして、液体噴射装置１１では、メンテナンス装置２１により、液体噴射ヘッド１３で生じる噴射不良の予防または解消のために、キャッピング、吸引クリーニング及びワイピングなどのメンテナンス動作を行う。   The maintenance device 21 includes a cap 22, a waste liquid passage 23 connected to the cap 22, a suction pump 24 provided in the middle of the waste liquid passage 23, a moving mechanism 25 that moves the cap 22, and the liquid ejecting head 13. And a wiping device 40 that performs In the liquid ejecting apparatus 11, maintenance operations such as capping, suction cleaning, and wiping are performed by the maintenance apparatus 21 in order to prevent or eliminate ejection defects that occur in the liquid ejecting head 13.

移動機構２５は、キャップ２２を図１に実線で示す退避位置と液体噴射ヘッド１３に接するキャッピング位置（図１に二点鎖線で示す）との間で移動させる。キャップ２２は、キャッピング位置に移動したときに、ノズル１２が開口する閉空間を形成する。このように、ノズル１２が開口する閉空間を形成することを、「キャッピング」という。液体噴射ヘッド１３が液体の噴射を行わない時には、キャッピングを行ってノズル１２の乾燥を抑制することによって、噴射不良の発生を予防する。   The moving mechanism 25 moves the cap 22 between a retracted position indicated by a solid line in FIG. 1 and a capping position (shown by a two-dot chain line in FIG. 1) in contact with the liquid ejecting head 13. The cap 22 forms a closed space in which the nozzle 12 opens when moved to the capping position. Forming a closed space in which the nozzle 12 is opened in this way is called “capping”. When the liquid ejecting head 13 does not eject the liquid, capping is performed to prevent the nozzle 12 from drying, thereby preventing ejection failure.

キャップ２２をキャッピング位置に配置した状態で吸引ポンプ２４を駆動し、ノズル１２に負圧を作用させると、その負圧によって液体噴射ヘッド１３から液体が吸引排出される吸引クリーニングが実行される。吸引クリーニングによって排出された液体は、廃液として廃液流路２３を通じて廃液収容体２６に収容される。   When the suction pump 24 is driven in a state where the cap 22 is located at the capping position and a negative pressure is applied to the nozzle 12, suction cleaning is performed in which liquid is sucked and discharged from the liquid jet head 13 by the negative pressure. The liquid discharged by the suction cleaning is stored as a waste liquid in the waste liquid container 26 through the waste liquid channel 23.

図２及び図３に示すように、液体噴射ヘッド１３は、ノズル１２が開口する開口面１３ａと、開口面１３ａに重なる枠体３０と、を有する。
図２に示すように、本実施形態の液体噴射ヘッド１３においては、複数のノズル１２が搬送方向Ｙ及び幅方向Ｘに対して斜めに交差する方向に並んでノズル列Ｎを形成する。また、液体噴射ヘッド１３には幅方向Ｘに所定の間隔をあけて複数のノズル列Ｎが配置される。 As shown in FIGS. 2 and 3, the liquid ejecting head 13 includes an opening surface 13 a in which the nozzle 12 opens and a frame body 30 that overlaps the opening surface 13 a.
As shown in FIG. 2, in the liquid jet head 13 of the present embodiment, a plurality of nozzles 12 are aligned in a direction that obliquely intersects the transport direction Y and the width direction X to form a nozzle row N. A plurality of nozzle rows N are arranged in the liquid jet head 13 with a predetermined interval in the width direction X.

枠体３０は、縁の一部がノズル列Ｎに沿って延びる開口３１を有しており、この開口３１を通じて、開口面１３ａのノズル１２が開口する領域を露出させる。なお、ノズル列Ｎが延びる方向を「延設方向」といい、開口３１の延設方向に延びる縁の部分を傾斜縁部３２という。   The frame 30 has an opening 31 with a part of the edge extending along the nozzle row N, and an area of the opening surface 13 a where the nozzle 12 is opened is exposed through the opening 31. A direction in which the nozzle row N extends is referred to as an “extension direction”, and an edge portion extending in the extension direction of the opening 31 is referred to as an inclined edge portion 32.

液体噴射装置１１は、開口面１３ａと幅方向Ｘに並ぶ位置に配置される受圧部３５ａを有する受圧部材３５と、弾性変形可能な払拭部材４１と、払拭部材４１の基端側を支持する支持部材４２と、を備える。払拭部材４１及び支持部材４２はワイピング装置４０（図１参照）を構成する。噴射動作や吸引クリーニングの後などに、支持部材４２に支持された払拭部材４１は、先端部分で開口面１３ａを払拭するワイピングを行う。   The liquid ejecting apparatus 11 supports a pressure receiving member 35 having a pressure receiving portion 35 a arranged at a position aligned with the opening surface 13 a and the width direction X, an elastically deformable wiping member 41, and a base end side of the wiping member 41. Member 42. The wiping member 41 and the support member 42 constitute a wiping device 40 (see FIG. 1). The wiping member 41 supported by the support member 42 performs wiping for wiping the opening surface 13a at the tip portion after the jetting operation or the suction cleaning.

払拭部材４１は、例えばエラストマーから構成される板状の部材であって、ノズル列Ｎと同じ延設方向に延びる。そして、払拭部材４１は、受圧部材３５に向けて幅方向Ｘに沿う払拭方向（図２，図３及び図５〜図８において白抜き矢印で示す方向）に移動することによって、ワイピングを行う。払拭部材４１は、搬送方向Ｙの長さを液体噴射ヘッド１３より長くすると、開口面１３ａとともに枠体３０の下面３０ａも払拭できる。   The wiping member 41 is a plate-like member made of, for example, an elastomer, and extends in the same extending direction as the nozzle row N. The wiping member 41 performs wiping by moving toward the pressure receiving member 35 in the wiping direction along the width direction X (the direction indicated by the white arrow in FIGS. 2, 3, and 5 to 8). The wiping member 41 can wipe the lower surface 30a of the frame 30 together with the opening surface 13a when the length in the transport direction Y is longer than that of the liquid jet head 13.

受圧部材３５は、例えば液体を吸収可能な多孔質部材からなり、幅方向Ｘ及び搬送方向Ｙにおける長さが払拭部材４１より長いことが好ましい。また、受圧部３５ａを平面とし、枠体３０の下面３０ａと面一となるように配置すると、受圧部３５ａと下面３０ａの間の段差が小さくなる。   The pressure receiving member 35 is made of, for example, a porous member that can absorb liquid, and the length in the width direction X and the conveyance direction Y is preferably longer than the wiping member 41. Further, when the pressure receiving portion 35a is a flat surface and is disposed so as to be flush with the lower surface 30a of the frame 30, the step between the pressure receiving portion 35a and the lower surface 30a is reduced.

液体噴射ヘッド１３と受圧部３５ａとの間には液体を保持可能な溝３６が設けられる。溝３６は、液体噴射ヘッド１３と受圧部材３５の互いに対向する外縁に沿う態様で搬送方向Ｙに沿って延びる。溝３６は、例えば、液体噴射ヘッド１３と受圧部材３５の間の段差であるが、その段差にエラストマーなどの部材を挟んだり接着剤で埋めたりして形成した隙間材３７を設けて、枠体３０の下面３０ａと開口面１３ａの間の段差を小さくしたものを溝３６としてもよい。   A groove 36 capable of holding liquid is provided between the liquid jet head 13 and the pressure receiving portion 35a. The groove 36 extends along the transport direction Y in a manner along outer edges of the liquid ejecting head 13 and the pressure receiving member 35 facing each other. The groove 36 is, for example, a step between the liquid jet head 13 and the pressure receiving member 35, and a gap member 37 formed by sandwiching a member such as an elastomer or filling with an adhesive in the step is provided, and the frame body The groove 36 may be formed by reducing the level difference between the lower surface 30a and the opening surface 13a.

払拭部材４１は溝３６と斜めに交差する延設方向に延設される。そして、払拭部材４１は、搬送方向Ｙに延びる溝３６と交差しながら溝３６を通過する。払拭部材４１の全体が溝３６を通過すると、払拭部材４１は液体噴射ヘッド１３から離れる。   The wiping member 41 extends in the extending direction that obliquely intersects the groove 36. The wiping member 41 passes through the groove 36 while intersecting the groove 36 extending in the transport direction Y. When the entire wiping member 41 passes through the groove 36, the wiping member 41 moves away from the liquid ejecting head 13.

図３に示すように、払拭部材４１は開口面１３ａに弾性変形した状態で接触し、受圧部材３５に向けて液体噴射ヘッド１３と相対移動することによって開口面１３ａの払拭を行う。そして、溝３６を通過した払拭部材４１が受圧部３５ａに接触すると、受圧部材３５は弾性変形した払拭部材４１の弾性力を受ける。   As shown in FIG. 3, the wiping member 41 contacts the opening surface 13 a in an elastically deformed state, and wipes the opening surface 13 a by moving relative to the liquid jet head 13 toward the pressure receiving member 35. And if the wiping member 41 which passed the groove | channel 36 contacts the pressure receiving part 35a, the pressure receiving member 35 will receive the elastic force of the wiping member 41 which elastically deformed.

払拭部材４１の全体が液体噴射ヘッド１３から離れると、溝３６を通過して受圧部材３５に接触する払拭部材４１及び払拭部材４１の弾性力を受ける受圧部材３５のうち少なくとも一方が、払拭部材４１の弾性変形を小さくする方向に移動する。例えば、払拭部材４１が、払拭部材４１を支持する支持部材４２とともに噴射方向Ｚに移動する。これにより、弾性変形していた払拭部材４１が復元変形する。その後、払拭部材４１は支持部材４２とともに払拭方向の反対方向に移動して、ワイピング開始時の位置まで戻る。   When the entire wiping member 41 is separated from the liquid jet head 13, at least one of the wiping member 41 that passes through the groove 36 and contacts the pressure receiving member 35 and the pressure receiving member 35 that receives the elastic force of the wiping member 41 is the wiping member 41. It moves in the direction to reduce the elastic deformation of. For example, the wiping member 41 moves in the ejection direction Z together with the support member 42 that supports the wiping member 41. Thereby, the wiping member 41 which has been elastically deformed is restored and deformed. Thereafter, the wiping member 41 moves in the direction opposite to the wiping direction together with the support member 42 and returns to the position at the start of wiping.

図４に示すように、液体噴射装置１１は、例えばキャップ２２と幅方向Ｘ（払拭方向）に並ぶ位置に、吸収部材４３を備えてもよい。吸収部材４３は、受圧部材３５に接触したときに、受圧部材３５に付着した液体及び溝３６に保持された液体を吸収する。この構成によれば、キャップ２２がキャッピング位置に移動するときに、吸収部材４３が受圧部材３５に接触して、受圧部材３５に付着した液体及び溝３６に保持された液体を除去する。この場合、受圧部材３５は液体を吸収可能な部材で構成しなくてもよい。また、受圧部材３５が液体を吸収可能な部材である場合、吸収部材４３が溝３６に保持された液体のみを吸収してもよい。   As illustrated in FIG. 4, the liquid ejecting apparatus 11 may include an absorbing member 43 at a position aligned with the cap 22 in the width direction X (wiping direction), for example. When the absorbing member 43 comes into contact with the pressure receiving member 35, the absorbing member 43 absorbs the liquid attached to the pressure receiving member 35 and the liquid held in the groove 36. According to this configuration, when the cap 22 moves to the capping position, the absorbing member 43 comes into contact with the pressure receiving member 35 and removes the liquid attached to the pressure receiving member 35 and the liquid held in the groove 36. In this case, the pressure receiving member 35 may not be formed of a member that can absorb liquid. When the pressure receiving member 35 is a member that can absorb liquid, the absorbing member 43 may absorb only the liquid held in the groove 36.

さらに、吸収部材４３及びキャップ２２を支持する支持部４４の下に、液体を吸収可能なシート４６と、シート４６を収容する収容部４５と、を配置すると、吸収部材４３及びキャップ２２から溢れた液体をシート４６及び収容部４５で受容することができる。また、液体を伝達可能な伝達部４７を吸収部材４３及びシート４６に接触させておくと、吸収部材４３が吸収した液体を伝達部４７に伝わせてシート４６の方に移動させることができる。   Furthermore, when a sheet 46 capable of absorbing liquid and a storage unit 45 for storing the sheet 46 are disposed under the support part 44 that supports the absorption member 43 and the cap 22, the liquid overflows from the absorption member 43 and the cap 22. The liquid can be received by the sheet 46 and the container 45. In addition, when the transmission unit 47 capable of transmitting the liquid is brought into contact with the absorbing member 43 and the sheet 46, the liquid absorbed by the absorbing member 43 can be transmitted to the transmitting unit 47 and moved toward the sheet 46.

次に、液体噴射装置１１の作用について説明する。
ワイピングを終了した払拭部材４１が液体を吸収可能な受圧部材３５と接触することにより、開口面１３ａから掻き取った液体を受圧部材３５に吸収させて、払拭部材４１から除去することができる。また、液体噴射ヘッド１３と受圧部材３５の間に溝３６を設けると、溝３６に液体が入り込んで保持されるので、液体噴射ヘッド１３に残る液体が少なくなる。なお、受圧部材３５と溝３６を隣接させておくと、溝３６に保持された液体が受圧部材３５に吸収される。 Next, the operation of the liquid ejecting apparatus 11 will be described.
When the wiping member 41 that has finished wiping comes into contact with the pressure receiving member 35 that can absorb the liquid, the pressure receiving member 35 can absorb the liquid scraped off from the opening surface 13 a and remove it from the wiping member 41. Further, when the groove 36 is provided between the liquid ejecting head 13 and the pressure receiving member 35, the liquid enters and is retained in the groove 36, so that the liquid remaining in the liquid ejecting head 13 is reduced. If the pressure receiving member 35 and the groove 36 are adjacent to each other, the liquid held in the groove 36 is absorbed by the pressure receiving member 35.

ただし、液体噴射ヘッド１３と受圧部３５ａの間にある溝３６が払拭部材４１と平行をなしていると、払拭部材４１が溝３６に引っかかって弾性変形し、その反動で撓み変位したときに、液体を飛散させてしまうおそれがある。その点、本実施形態では、払拭部材４１が溝３６と交差する方向に延びるので、払拭部材４１が溝３６に引っかかりにくい。そのため、液体噴射ヘッド１３から離れた払拭部材４１が払拭方向に液体を飛散させる、という問題が発生しにくい。   However, if the groove 36 between the liquid ejecting head 13 and the pressure receiving portion 35a is parallel to the wiping member 41, the wiping member 41 is caught in the groove 36 and elastically deformed, and when it is deflected and displaced by the reaction, There is a risk of liquid splashing. In this respect, in the present embodiment, the wiping member 41 extends in a direction intersecting with the groove 36, so that the wiping member 41 is not easily caught by the groove 36. Therefore, the problem that the wiping member 41 separated from the liquid ejecting head 13 scatters the liquid in the wiping direction hardly occurs.

上記実施形態によれば、以下のような効果を得ることができる。
（１）払拭部材４１が払拭の終端で溝３６を通過すると、払拭により掻き集めた液体が溝３６に入るので、液体噴射ヘッド１３に残る液体を少なくすることができる。そして、払拭部材４１は、延設方向の端部が溝３６と交差しながら液体噴射ヘッド１３から離れるので、払拭の終了時に溝３６に引っかかりにくい。また、払拭部材４１は液体噴射ヘッド１３から離れて受圧部３５ａに接触した状態から噴射方向Ｚに移動するので、払拭部材４１が復元変形しながら受圧部３５ａから離れることになる。そのため、払拭部材４１が受圧部３５ａから離れるときに液体が飛散しにくい。したがって、払拭に伴う液体の飛散を抑制することができる。 According to the above embodiment, the following effects can be obtained.
(1) When the wiping member 41 passes through the groove 36 at the end of wiping, the liquid scraped by wiping enters the groove 36, so that the liquid remaining in the liquid ejecting head 13 can be reduced. And since the wiping member 41 leaves | separates from the liquid ejecting head 13 while the edge part of the extending direction cross | intersects the groove | channel 36, it is hard to be caught in the groove | channel 36 at the time of completion | finish of wiping. Further, since the wiping member 41 moves away from the liquid ejecting head 13 and contacts the pressure receiving portion 35a in the ejection direction Z, the wiping member 41 is separated from the pressure receiving portion 35a while being deformed and deformed. Therefore, it is difficult for the liquid to scatter when the wiping member 41 moves away from the pressure receiving portion 35a.

上記実施形態は以下に示す変更例のように変更してもよい。また、上記実施形態に含まれる構成と下記変更例に含まれる構成とを任意に組み合わせてもよいし、下記変更例に含まれる構成同士を任意に組み合わせてもよい。   You may change the said embodiment like the example of a change shown below. Further, the configuration included in the above embodiment and the configuration included in the following modification example may be arbitrarily combined, and the configurations included in the following modification example may be arbitrarily combined.

・液体噴射ヘッド１３が枠体３０を有さず、開口面１３ａと受圧部３５ａの間に溝３６があってもよい。この場合、開口面１３ａと平面からなる受圧部３５ａ（受圧面）が面一をなすと、開口面１３ａと受圧部３５ａの間の段差が小さくなる。   The liquid jet head 13 may not have the frame body 30, and the groove 36 may be provided between the opening surface 13a and the pressure receiving portion 35a. In this case, when the pressure receiving portion 35a (pressure receiving surface) composed of a flat surface with the opening surface 13a is flush, the step between the opening surface 13a and the pressure receiving portion 35a is reduced.

・図５に示す第１変更例及び図６に示す第２変更例の液体噴射ヘッド１３のように、ノズル列Ｎの延設方向が幅方向Ｘに沿う方向であってもよい。この場合、枠体３０の開口３１は傾斜縁部３２を有さない。   The extending direction of the nozzle row N may be a direction along the width direction X as in the liquid jet head 13 of the first modified example shown in FIG. 5 and the second modified example shown in FIG. In this case, the opening 31 of the frame 30 does not have the inclined edge 32.

・図５に示す第１変更例のように、液体噴射ヘッド１３の幅方向Ｘの端部、溝３６及び受圧部３５ａの幅方向Ｘの端部が、幅方向Ｘ及び搬送方向Ｙと斜めに交差する方向に延びてもよい。この場合、払拭部材４１は、搬送方向Ｙに延びる態様で設けると、溝３６と斜めに交差する。   As in the first modification shown in FIG. 5, the end in the width direction X of the liquid jet head 13, the end in the width direction X of the groove 36 and the pressure receiving portion 35 a are inclined with respect to the width direction X and the transport direction Y. You may extend in the direction which crosses. In this case, when the wiping member 41 is provided so as to extend in the transport direction Y, it crosses the groove 36 obliquely.

・図５に示す第１変更例のように、受圧部材３５の搬送方向Ｙにおける長さが払拭部材４１より短くてもよい。
・図６に示す第２変更例のように、液体噴射ヘッド１３の幅方向Ｘの端部及び溝３６は直線状でなくてもよい。例えば、第２変更例では、液体噴射ヘッド１３の幅方向Ｘの端部が、ノズル列Ｎの配置に併せて搬送方向Ｙ及び幅方向Ｘに延びる階段状になっている。この場合、払拭部材４１は、少なくとも搬送方向Ｙにおける両端から中央に向けて延びる部分が溝３６と交差しながら溝３６を通過するように、搬送方向Ｙにおける両端側の部分が搬送方向Ｙ及び幅方向Ｘに対して斜めに延びるように屈曲させるとよい。その他、溝３６が曲線状に湾曲していてもよいし、払拭部材４１が曲線状に湾曲していてもよい。 -Like the 1st modification shown in FIG. 5, the length in the conveyance direction Y of the pressure receiving member 35 may be shorter than the wiping member 41. FIG.
As in the second modification example illustrated in FIG. 6, the end portion of the liquid jet head 13 in the width direction X and the groove 36 may not be linear. For example, in the second modified example, the end portion in the width direction X of the liquid jet head 13 has a step shape extending in the transport direction Y and the width direction X in accordance with the arrangement of the nozzle rows N. In this case, the wiping member 41 is configured so that at least the portions extending from both ends in the transport direction Y toward the center pass through the groove 36 while intersecting the groove 36, and the portions on both ends in the transport direction Y are in the transport direction Y and width. It may be bent so as to extend obliquely with respect to the direction X. In addition, the groove 36 may be curved and the wiping member 41 may be curved.

・図７に示す第３変更例及び図８に示す第４変更例のように、受圧部材３５を付勢する付勢部材３８を設け、受圧部材３５が払拭部材４１の弾性力を受圧部３５ａに受けた場合に、付勢部材３８の付勢力に抗して払拭部材４１の弾性変形を小さくする方向に移動するようにしてもよい。この場合、払拭部材４１が払拭方向に移動して、その全体が溝３６を通過して受圧部材３５の方に移行すると、受圧部材３５が上方（噴射方向Ｚの反対方向）に移動して払拭部材４１が復元変形するので、払拭部材４１は引き続き払拭方向に移動して受圧部材３５から離れてもよい。この構成によれば、払拭部材４１の弾性力と付勢部材の付勢力のバランスによって受圧部材３５が移動するので、受圧部材３５を移動させるための制御を行う必要がない。   As in the third modified example shown in FIG. 7 and the fourth modified example shown in FIG. 8, a biasing member 38 that biases the pressure receiving member 35 is provided, and the pressure receiving member 35 applies the elastic force of the wiping member 41 to the pressure receiving portion 35a. If it is received, the wiping member 41 may move in a direction to reduce the elastic deformation against the urging force of the urging member 38. In this case, when the wiping member 41 moves in the wiping direction and the whole passes through the groove 36 and moves toward the pressure receiving member 35, the pressure receiving member 35 moves upward (in the direction opposite to the injection direction Z) and is wiped. Since the member 41 is restored and deformed, the wiping member 41 may continue to move in the wiping direction and leave the pressure receiving member 35. According to this configuration, since the pressure receiving member 35 moves due to the balance between the elastic force of the wiping member 41 and the biasing force of the biasing member, it is not necessary to perform control for moving the pressure receiving member 35.

付勢部材３８は、図７に示す第３変更例のような円筒状のコイルばねであってもよいし、図８に示す第４変更例のようなねじりコイルばねであってもよい。
なお、図８に示す第４変更例のように、受圧部材３５がねじりコイルばねである付勢部材３８の付勢力を受けている場合、払拭部材４１が払拭方向（図８では左方向）に移動すると、払拭部材４１の弾性力が付勢部材３８の付勢力を上回ったときに、受圧部材３５が回動により移動する。そのため、払拭部材４１の全体が溝３６を通過して受圧部材３５に接触した後、引き続き払拭方向に移動することにより、受圧部材３５が付勢部材３８の付勢力に抗して回動して、払拭部材４１の弾性変形が小さくなる。その後、払拭部材４１は引き続き払拭方向に移動して受圧部材３５から離れるとよい。 The urging member 38 may be a cylindrical coil spring as in the third modification shown in FIG. 7, or may be a torsion coil spring as in the fourth modification shown in FIG.
In addition, when the pressure receiving member 35 receives the urging force of the urging member 38 that is a torsion coil spring as in the fourth modified example shown in FIG. 8, the wiping member 41 is in the wiping direction (leftward in FIG. 8). When moved, when the elastic force of the wiping member 41 exceeds the urging force of the urging member 38, the pressure receiving member 35 is moved by rotation. Therefore, after the entire wiping member 41 passes through the groove 36 and contacts the pressure receiving member 35, the pressure receiving member 35 rotates against the urging force of the urging member 38 by continuously moving in the wiping direction. The elastic deformation of the wiping member 41 is reduced. Thereafter, the wiping member 41 may continue to move in the wiping direction and leave the pressure receiving member 35.

・図９に示す第５変更例のように、液体噴射装置１１は、幅方向Ｘに延びるガイド軸５１と、ガイド軸５１に案内されて幅方向Ｘに沿って往復移動するキャリッジ５２とを備え、このキャリッジ５２が液体噴射ヘッド１３を保持するシリアルタイプのものであってもよい。この場合、液体噴射ヘッド１３に供給される液体を収容した液体収容体１５をキャリッジ５２が保持するオンキャリッジタイプでもよいし、液体収容体１５を固定した位置に配置するオフキャリッジタイプでもよい。   As in the fifth modification shown in FIG. 9, the liquid ejecting apparatus 11 includes a guide shaft 51 extending in the width direction X, and a carriage 52 that is guided by the guide shaft 51 and reciprocates along the width direction X. The carriage 52 may be of a serial type that holds the liquid jet head 13. In this case, an on-carriage type in which the carriage 52 holds the liquid container 15 containing the liquid supplied to the liquid ejecting head 13 or an off-carriage type in which the liquid container 15 is disposed at a fixed position may be used.

第５変更例の液体噴射装置１１においては、媒体Ｓを支持する支持台５３と、ワイピング装置４０と、キャップ２２とが幅方向Ｘに並ぶよう配置される。また、キャリッジ５２は、液体噴射ヘッド１３と幅方向Ｘに並ぶ位置に受圧部材３５を保持し、液体噴射ヘッド１３と受圧部材３５の間には溝３６が設けられる。そして、液体噴射ヘッド１３を幅方向Ｘに沿って移動させて払拭部材４１で開口面１３ａを払拭することにより、ワイピングを行う。この場合、液体噴射ヘッド１３の移動方向（図９では右方向）の反対方向が払拭方向（図９では白抜き矢印で示す左方向）となる。このように、液体噴射ヘッド１３が移動してワイピングを行ってもよい。そして、液体噴射ヘッド１３を払拭した払拭部材４１は、溝３６と交差した後、キャリッジ５２に保持された受圧部材３５に接触する。   In the liquid ejecting apparatus 11 according to the fifth modification, the support base 53 that supports the medium S, the wiping apparatus 40, and the cap 22 are arranged in the width direction X. The carriage 52 holds the pressure receiving member 35 at a position aligned with the liquid ejecting head 13 in the width direction X, and a groove 36 is provided between the liquid ejecting head 13 and the pressure receiving member 35. Then, wiping is performed by moving the liquid ejecting head 13 along the width direction X and wiping the opening surface 13 a with the wiping member 41. In this case, the direction opposite to the moving direction of the liquid jet head 13 (the right direction in FIG. 9) is the wiping direction (the left direction indicated by the white arrow in FIG. 9). In this way, the liquid ejecting head 13 may move to perform wiping. The wiping member 41 that has wiped the liquid ejecting head 13 contacts the pressure receiving member 35 held by the carriage 52 after intersecting the groove 36.

・液体噴射ヘッド１３が噴射する液体はインクに限らず、例えば機能材料の粒子が液体に分散又は混合されてなる液状体などであってもよい。例えば、液晶ディスプレイ、ＥＬ（エレクトロルミネッセンス）ディスプレイ及び面発光ディスプレイの製造などに用いられる電極材や色材（画素材料）などの材料を分散または溶解のかたちで含む液状体を噴射して記録を行う構成にしてもよい。   The liquid ejected by the liquid ejecting head 13 is not limited to ink, and may be, for example, a liquid material in which functional material particles are dispersed or mixed in the liquid. For example, recording is performed by ejecting a liquid material in which a material such as an electrode material or a color material (pixel material) used for manufacturing a liquid crystal display, an EL (electroluminescence) display, and a surface emitting display is dispersed or dissolved. It may be configured.

・媒体Ｓは用紙に限らず、プラスチックフィルムや薄い板材などでもよいし、捺染装置などに用いられる布帛であってもよい。また、媒体Ｓは所定のサイズに切断された単票でなくてもよく、例えば円筒状に巻かれたロール状の媒体であってもよいし、Ｔシャツなど、任意の形状の衣類等であってもよいし、食器または文具のような任意の形状の立体物であってもよい。   The medium S is not limited to paper, but may be a plastic film, a thin plate, or the like, or may be a fabric used in a printing apparatus. Further, the medium S does not have to be a single sheet cut to a predetermined size. For example, the medium S may be a roll-shaped medium wound in a cylindrical shape, or a garment having an arbitrary shape such as a T-shirt. It may be a three-dimensional object of any shape such as tableware or stationery.
