The upper lid 13 and the front lid 14 are respectively rotated to a predetermined angle so that the upper lid 13 and the front lid 14 are arranged in a closed position overlapping the housing 12 and an open position shown in FIG.
上蓋１３を開位置に配置すると、筐体１２内に媒体Ｓを挿入するための挿入口１５が露出する。開位置に配置された上蓋１３は、挿入口１５に挿入される媒体Ｓを支持する支持部材として機能する。 When the upper lid 13 is placed in the open position, the insertion port 15 for inserting the medium S into the housing 12 is exposed. The upper lid 13 arranged at the open position functions as a support member that supports the medium S inserted into the insertion port 15.
前蓋１４を開位置に配置すると、筐体１２内から媒体Ｓを排出するための排出口１６が露出する。開位置に配置された前蓋１４は、排出口１６から排出される媒体Ｓを受容する支持部材として機能する。 When the front lid 14 is placed in the open position, the ejection port 16 for ejecting the medium S from the inside of the housing 12 is exposed. The front lid 14 arranged in the open position functions as a support member that receives the medium S discharged from the discharge port 16.
筐体１２において、挿入口１５が開口する外壁を上壁部２１、上壁部２１と実質的に平行をなして配置される外壁を底壁部２２、排出口１６が開口する外壁を前壁部２３、前壁部２３と実質的に平行をなして配置される外壁を後壁部２４という。また、筐体１２において、上壁部２１、底壁部２２、前壁部２３及び後壁部２４と交差する一対の外壁を側壁部２５，２６という。そして、筐体１２において、上壁部２１側を天面側、底壁部２２側を底面側ということがある。 In the housing 12, the outer wall where the insertion port 15 is opened is the upper wall portion 21, the outer wall which is arranged substantially parallel to the upper wall portion 21 is the bottom wall portion 22, and the outer wall where the discharge port 16 is opened is the front wall. The outer wall arranged substantially parallel to the portion 23 and the front wall portion 23 is referred to as a rear wall portion 24. Further, in the housing 12, a pair of outer walls intersecting the upper wall portion 21, the bottom wall portion 22, the front wall portion 23, and the rear wall portion 24 are referred to as side wall portions 25 and 26. In the case 12, the upper wall portion 21 side may be referred to as the top surface side, and the bottom wall portion 22 side may be referred to as the bottom surface side.
上壁部２１の表面側（天面側）には、液体噴射装置１１の操作を行うための操作部１７と、操作部１７の操作結果や液体噴射装置１１の動作状況等を表示するための表示部１８とが配置されている。上壁部２１の裏面側には、例えば前壁部２３及び側壁部２５に近い位置に、液体噴射装置１１が備える各種機構の制御を行う制御部１００が設けられている。 On the front surface side (top surface side) of the upper wall portion 21, an operation section 17 for operating the liquid ejecting apparatus 11 and an operation result of the operation section 17 and an operation status of the liquid ejecting apparatus 11 are displayed. The display unit 18 is arranged. On the back surface side of the upper wall portion 21, for example, a control unit 100 that controls various mechanisms included in the liquid ejecting apparatus 11 is provided near the front wall portion 23 and the side wall portion 25.
図２に示すように、筐体１２内には、媒体支持部２７ａを有する支持部材２７と、媒体支持部２７ａに支持された媒体Ｓに対して液体を噴射する液体噴射ヘッド３１と、液体噴射ヘッド３１を保持して往復移動するキャリッジ３３と、が収容されている。媒体支持部２７ａは、挿入口１５から排出口１６に向けて延びる搬送路（図２に二点鎖線で示す）に沿って搬送される媒体Ｓを支持する複数の突部からなる。また、筐体１２内には、キャリッジ３３の移動を案内するためのガイド軸３４が架設されている。 As shown in FIG. 2, in the housing 12, a supporting member 27 having a medium supporting portion 27a, a liquid ejecting head 31 for ejecting a liquid to the medium S supported by the medium supporting portion 27a, and a liquid ejecting head. A carriage 33 that holds the head 31 and reciprocates is housed. The medium support portion 27a is composed of a plurality of protrusions that support the medium S that is transported along the transport path (indicated by the chain double-dashed line in FIG. 2) extending from the insertion port 15 toward the discharge port 16. Further, a guide shaft 34 for guiding the movement of the carriage 33 is installed inside the housing 12.
液体噴射ヘッド３１は、液体を液滴として噴射する複数のノズル３２を有する。液体噴射ヘッド３１は、筐体１２の長手方向（図２では左右方向）における第１端側（図２では右端側）をホーム位置として、ホーム位置から長手方向における第２端側（図２では左端側）に向かう往路移動と、第２端側からホーム位置に向かう復路移動とを交互に行う。 The liquid ejecting head 31 has a plurality of nozzles 32 that eject liquid as droplets. The liquid ejecting head 31 has a first end side (right end side in FIG. 2) in the longitudinal direction (left and right direction in FIG. 2) of the housing 12 as a home position, and a second end side in the longitudinal direction from the home position (in FIG. 2). The forward movement toward the left end side) and the backward movement toward the home position from the second end side are alternately performed.
本実施形態において、液体噴射ヘッド３１が液体を噴射する方向を噴射方向、媒体支持部２７ａ上において挿入口１５から排出口１６に向けて媒体Ｓが搬送される方向を搬送方向、液体噴射ヘッド３１の往路移動方向を走査方向という。本実施形態において、噴射方向は鉛直下方である。 In the present embodiment, the direction in which the liquid ejecting head 31 ejects the liquid is the ejecting direction, the direction in which the medium S is conveyed from the insertion port 15 to the ejecting port 16 on the medium supporting portion 27 a is the conveying direction, and the liquid ejecting head 31. The forward movement direction of is called the scanning direction. In this embodiment, the injection direction is vertically downward.
支持部材２７は、媒体支持部２７ａの周囲に凹設された受容凹部２７ｂを有する。受容凹部２７ｂには、液体を吸収可能なシート２９を収容することが好ましい。シート２９は、不織布または多孔質体などから構成され、媒体Ｓの縁まで余白無く印刷を施す縁なし印刷を行う場合に、液体噴射ヘッド３１から媒体Ｓの端部に向けて噴射されて、媒体Ｓに受容されずにはみ出た液滴を受容する。このように、受容凹部２７ｂ及びシート２９は、液体噴射ヘッド３１が噴射した液体を廃液として受容する廃液受容部３０として機能する。なお、廃液受容部３０が受容する廃液を「噴射廃液」という。 The support member 27 has a receiving recess 27b that is recessed around the medium support 27a. A sheet 29 capable of absorbing liquid is preferably housed in the receiving recess 27b. The sheet 29 is made of a non-woven fabric or a porous body, and is ejected from the liquid ejecting head 31 toward the end of the medium S when performing marginless printing in which printing is performed with no margin up to the edge of the medium S. It receives the droplets that have not been received by S and have overflowed. Thus, the receiving recess 27b and the sheet 29 function as the waste liquid receiving portion 30 that receives the liquid ejected by the liquid ejecting head 31 as the waste liquid. The waste liquid received by the waste liquid receiving section 30 is referred to as “jet waste liquid”.
筐体１２内において、ホーム位置付近には、液体噴射ヘッド３１のメンテナンスを行うためのメンテナンス機構３５が配置されている。メンテナンス機構３５は、ホーム位置と対応する位置に配置されるキャップ３６と、キャップ３６に吸引チューブ３７を介して接続される吸引機構３８と、キャップ３６を昇降移動させる昇降機構３９と、液体噴射ヘッド３１を払拭する払拭部材４０と、を備える。 A maintenance mechanism 35 for performing maintenance of the liquid ejecting head 31 is arranged in the housing 12 near the home position. The maintenance mechanism 35 includes a cap 36 arranged at a position corresponding to the home position, a suction mechanism 38 connected to the cap 36 via a suction tube 37, an elevating mechanism 39 for moving the cap 36 up and down, and a liquid ejecting head. And a wiping member 40 for wiping 31.
昇降機構３９は、キャップ３６をキャッピング位置と、キャッピング位置よりも底壁部２２に近い退避位置との間で移動させる。液体噴射ヘッド３１がホーム位置にあるときにキャップ３６がキャッピング位置に移動すると、キャップ３６はノズル３２が開口する閉空間を形成する状態（図１２に示す状態）となり、ノズル３２の乾燥を抑制する。このように、キャップ３６によってノズル３２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。液体を噴射しない電源オフ時などに、液体噴射ヘッド３１はホーム位置に移動して、キャップ３６がキャッピング位置に移動してキャッピングする。キャップ３６がキャッピング位置から退避位置に移動すると、キャッピングは解除される。 The elevating mechanism 39 moves the cap 36 between a capping position and a retracted position closer to the bottom wall portion 22 than the capping position. When the cap 36 moves to the capping position while the liquid ejecting head 31 is at the home position, the cap 36 enters a state of forming a closed space in which the nozzle 32 opens (the state shown in FIG. 12) and suppresses the drying of the nozzle 32. .. Thus, forming a closed space in which the nozzle 32 is opened by the cap 36 is called “capping”. The liquid ejecting head 31 moves to the home position and the cap 36 moves to the capping position to cap when the power is turned off without ejecting the liquid. When the cap 36 moves from the capping position to the retracted position, capping is released.
吸引機構３８は、例えば、弾性変形可能なチューブをコロなどの押圧部材が押し潰しつつ移動することで吸引力を発生させるチューブポンプ等からなる吸引ポンプである。キャッピング時に吸引機構３８が駆動すると、閉空間が減圧されて負圧になる。これにより、ノズル３２を通じて液体噴射ヘッド３１から液体が排出される吸引クリーニングが実行される。吸引クリーニングは、例えば気泡が混入するなどして液体の噴射不良が生じた場合などに、噴射不良を解消するためのメンテナンス動作として行われる。 The suction mechanism 38 is, for example, a suction pump such as a tube pump that generates a suction force by moving an elastically deformable tube while a pressing member such as a roller crushes the tube. When the suction mechanism 38 is driven during capping, the closed space is depressurized to a negative pressure. As a result, suction cleaning is performed in which the liquid is ejected from the liquid ejecting head 31 through the nozzle 32. The suction cleaning is performed as a maintenance operation for eliminating the ejection failure, for example, when the ejection failure of the liquid occurs due to the inclusion of bubbles.
払拭部材４０は、液体噴射ヘッド３１が液体を噴射した後や、吸引クリーニングの後などに、液体噴射ヘッド３１に付着した液体などの異物を払拭する。このように払拭部材４０が液体噴射ヘッド３１を払拭するメンテナンス動作をワイピングという。 The wiping member 40 wipes foreign matter such as liquid adhered to the liquid ejecting head 31 after the liquid ejecting head 31 ejects liquid or after suction cleaning. The maintenance operation in which the wiping member 40 wipes the liquid ejecting head 31 in this manner is called wiping.
その他、噴射不良を解消するためのメンテナンス動作として、液体噴射ヘッド３１が退避位置にあるキャップ３６または廃液受容部３０に向けて液滴を吐き捨てるフラッシングを行うこともある。なお、吸引クリーニングやフラッシングなどに伴って液体噴射ヘッド３１から廃液として排出され、キャップ３６に受容された後に吸引機構３８の駆動により排出される廃液を「吸引廃液」という。 In addition, as a maintenance operation for eliminating the ejection failure, the liquid ejection head 31 may perform flushing in which the liquid droplets are ejected toward the cap 36 or the waste liquid receiving section 30 in the retracted position. It should be noted that the waste liquid discharged from the liquid jet head 31 as a result of suction cleaning, flushing, and the like, discharged by the drive of the suction mechanism 38 after being received by the cap 36, is called “suction waste liquid”.
図３に示すように、液体噴射装置１１は、筐体１２の底面側に、廃液収容体６０が着脱可能に装着される装着室４１と、装着室４１を覆う蓋１９と、を備える。廃液収容体６０は、噴射廃液と吸引廃液の両方を収容する廃液収容容器６１を有する。装着室４１の内部には、吸引廃液を排出する排出部４２と、制御部１００と図示しない信号線で接続された基板接続部４３と、が設けられる。 As shown in FIG. 3, the liquid ejecting apparatus 11 includes, on the bottom surface side of the housing 12, a mounting chamber 41 in which the waste liquid container 60 is removably mounted, and a lid 19 that covers the mounting chamber 41.

装着室４１内には、廃液受容部３０（図２参照）から延びる１または複数の廃液伝達部４８を突出させることが好ましい。廃液伝達部４８を複数（本実施形態では４つ）設ける場合、装着室４１の長手方向（本実施形態では接続方向Ｍ）に沿って並ぶように配置するとよい。 It is preferable that one or a plurality of waste liquid transfer portions 48 extending from the waste liquid receiving portion 30 (see FIG. 2) project into the mounting chamber 41. When a plurality of (four in this embodiment) waste liquid transfer units 48 are provided, they may be arranged side by side along the longitudinal direction of the mounting chamber 41 (connection direction M in this embodiment).
図４に示すように、装着室４１内には、廃液収容容器６１を係止する係止部４９を設けることが好ましい。係止部４９は、例えば装着室４１内に突出する板ばねとすることができる。この場合、装着室４１内に入った廃液収容容器６１が接続方向Ｍに移動したときに、係止部４９が廃液収容容器６１を係止する構成にするとよい。 As shown in FIG. 4, it is preferable that a lock portion 49 that locks the waste liquid storage container 61 is provided in the mounting chamber 41. The locking portion 49 may be, for example, a leaf spring protruding into the mounting chamber 41. In this case, when the waste liquid storage container 61 that has entered the mounting chamber 41 moves in the connection direction M, the locking portion 49 may lock the waste liquid storage container 61.
図５に示すように、装着室４１は、支持部材２７より底面側に配置されて、底面側が開口する箱状の収容部材２８により形成される。また、支持部材２７と収容部材２８の間には、接続方向Ｍに沿ってスライド移動可能なスライダー５０が配置される。スライダー５０は、底面側に向けて突出する伝達突部５１を有する。伝達突部５１は、液体を吸収可能な吸収シート５３で覆うとよい。 As shown in FIG. 5, the mounting chamber 41 is formed on the bottom surface side of the support member 27 and is formed by a box-shaped housing member 28 having an opening on the bottom surface side.

Will be extended to.
シート２９が受容した噴射廃液は、延設部２９ａ及び吸収シート５３（吸収シート５３がない場合は伝達突部５１）を伝って流下する。これにより、シート２９の延設部２９ａ、吸収シート５３及び伝達突部５１は、廃液伝達部４８を構成する。なお、スライダー５０の移動に伴って延設部２９ａが吸収シート５３から離れないように、延設部２９ａを伝達突部５１の方に押し付ける補助部材５４を設けるとよい（図１１を併せて参照）。 The jetted waste liquid received by the sheet 29 flows down along the extending portion 29a and the absorbing sheet 53 (the transmitting projection 51 when the absorbing sheet 53 is not provided). As a result, the extended portion 29a of the sheet 29, the absorbent sheet 53, and the transmission protrusion 51 form the waste liquid transmission portion 48. An auxiliary member 54 that pushes the extension portion 29a toward the transmission protrusion 51 may be provided so that the extension portion 29a does not separate from the absorbent sheet 53 as the slider 50 moves (see also FIG. 11). ).

Further, it is preferable to provide a guide protrusion 83a extending in the connecting direction M in the recess 83. The inner wall extending in the connection direction M of the recess 83 to which the circuit board 82 is attached constitutes a part of the side wall 63.
廃液導入部８１は、廃液収容容器６１の側壁６３，６４及び底壁６２と交差する壁部６５に設けられる。廃液導入部８１は、例えば、壁部６５に設けられた貫通孔６５ａと、貫通孔６５ａを囲む環状のシール部材８１ａと、シール部材８１ａを押さえる環状部材８１ｂと、によって構成される。 The waste liquid introducing portion 81 is provided on a wall portion 65 that intersects the side walls 63, 64 and the bottom wall 62 of the waste liquid storage container 61. The waste liquid introducing portion 81 is configured by, for example, a through hole 65a provided in the wall portion 65, an annular seal member 81a surrounding the through hole 65a, and an annular member 81b that presses the seal member 81a.
廃液収容体６０は、廃液収容室６１ａに収容される廃液を吸収可能な吸収部材７０を備えることが好ましい。吸収部材７０として、噴射廃液を吸収する第１吸収部材７０Ｆと、吸引廃液を吸収する第２吸収部材７０Ｓとを設けることが好ましい。さらに、第１吸収部材７０Ｆと第２吸収部材７０Ｓの間には、液体の流動を抑制する遮蔽シート７１を配置することが好ましい。吸収部材７０（７０Ｆ，７０Ｓ）の大きさ及び数は、吸収する廃液の排出量に応じて変更することができる。例えば、本実施形態では、第２吸収部材７０Ｓは板状のものを４つ設けて、底壁６２側から順に層をなすように重ねている。 The waste liquid container 60 preferably includes an absorbing member 70 capable of absorbing the waste liquid stored in the waste liquid storage chamber 61a. As the absorbing member 70, it is preferable to provide a first absorbing member 70F that absorbs the injection waste liquid and a second absorbing member 70S that absorbs the suction waste liquid. Furthermore, it is preferable to arrange a shielding sheet 71 that suppresses the flow of the liquid between the first absorbing member 70F and the second absorbing member 70S. The size and number of the absorbing members 70 (70F, 70S) can be changed according to the amount of discharged waste liquid to be absorbed. For example, in the present embodiment, the second absorbing member 70S is provided with four plate-shaped members, which are layered in order from the bottom wall 62 side.
廃液収容容器６１には、底壁６２から廃液収容室６１ａ内に突出する係止突部６１ｂと側壁６３，６４及び壁部６６から廃液収容室６１ａ内に突出する係止突部６１ｃとを設けるとよい。この場合、第２吸収部材７０Ｓに係止突部６１ｂ，６１ｃとそれぞれ係合する切込み７０ｂ，７０ｃを入れて、切込み７０ｂ，７０ｃに係止突部６１ｂ，６１ｃをそれぞれ挿入する態様で第２吸収部材７０Ｓを廃液収容室６１ａに収容すると、廃液収容室６１ａ内における第２吸収部材７０Ｓの移動が抑制される。また、遮蔽シート７１に切り込みを入れて切片７１ｄを立ち上げるとともに、第１吸収部材７０Ｆに切片７１ｄと係合する切込み７０ｄを入れて、切込み７０ｄに切片７１ｄを挿入した状態で第１吸収部材７０Ｆと遮蔽シート７１を廃液収容室６１ａに収容するとよい。 The waste liquid storage container 61 is provided with a locking projection 61b projecting from the bottom wall 62 into the waste liquid storage chamber 61a and a locking projection 61c projecting from the side walls 63 and 64 and the wall 66 into the waste liquid storage chamber 61a. Good. In this case, the second absorbing member 70S is provided with the cutouts 70b and 70c engaging with the locking projections 61b and 61c, respectively, and the locking projections 61b and 61c are inserted into the cutouts 70b and 70c, respectively. When the member 70S is stored in the waste liquid storage chamber 61a, the movement of the second absorbing member 70S in the waste liquid storage chamber 61a is suppressed. In addition, a cut is made in the shielding sheet 71 to raise the piece 71d, a cut 70d that engages with the piece 71d is made in the first absorbent member 70F, and the piece 71d is inserted in the cut 70d. The shielding sheet 71 may be stored in the waste liquid storage chamber 61a.
第１吸収部材７０Ｆ及び遮蔽シート７１を廃液収容室６１ａに収容するときに、遮蔽シート７１を係止突部６１ｂ，６１ｃで支持するように配置すると、廃液を吸収した第１吸収部材７０Ｆが自重で下方に沈まないように、係止突部６１ｂ，６１ｃで支えることができる。本実施形態では、廃液収容容器６１の壁部６５に段差部６５ｄを設けて、段差部６５ｄでも遮蔽シート７１を支持するようにしている（図１２を併せて参照）。 When the first absorbing member 70F and the shielding sheet 71 are accommodated in the waste liquid storage chamber 61a, if the shielding sheet 71 is arranged so as to be supported by the locking projections 61b and 61c, the first absorbing member 70F that has absorbed the waste liquid has its own weight. It can be supported by the locking protrusions 61b and 61c so as not to sink below. In the present embodiment, the step portion 65d is provided on the wall portion 65 of the waste liquid storage container 61, and the shielding sheet 71 is also supported by the step portion 65d (see also FIG. 12).
廃液収容室６１ａの天井部分を形成する蓋体６７には、挿入方向Ｎへの移動に伴って装着室４１（図３参照）に入るときに、廃液受容部３０（図６参照）が受容した噴射廃液を導入可能な態様で挿入方向Ｎに向けて開口する廃液導入口６７ａが設けられる（図１２を併せて参照）。 The lid 67, which forms the ceiling of the waste liquid storage chamber 61a, is received by the waste liquid receiving portion 30 (see FIG. 6) when entering the mounting chamber 41 (see FIG. 3) along with the movement in the insertion direction N. A waste liquid introduction port 67a is provided which opens in the insertion direction N in a manner that the jetted waste liquid can be introduced (see also FIG. 12).
本実施形態の廃液収容容器６１には、接続方向Ｍに並ぶ複数（４つ）の廃液導入口６７ａを設けている。また、第１吸収部材７０Ｆには、４つの廃液導入口６７ａのうちの３つと対応する位置に、貫通孔７０ａが形成されている。４つの廃液導入口６７ａのうちの残る１つの廃液導入口６７ａは、第１吸収部材７０Ｆの端部（接続方向Ｍにおける先端側）と対応する位置に配置される。 The waste liquid storage container 61 of the present embodiment is provided with a plurality (four) of waste liquid introduction ports 67a arranged in the connection direction M. Further, through holes 70a are formed in the first absorbing member 70F at positions corresponding to three of the four waste liquid introducing ports 67a. The remaining one waste liquid introduction port 67a among the four waste liquid introduction ports 67a is arranged at a position corresponding to the end portion (the front end side in the connection direction M) of the first absorbing member 70F.
図１１に示すように、第１吸収部材７０Ｆの切込み７０ｄに挿入可能な挿入突部６７ｄを蓋体６７に突設し、切込み７０ｄに挿入突部６７ｄを挿入する態様で蓋体６７を取り付けるようにすると、遮蔽シート７１及び第１吸収部材７０Ｆの移動を抑制することができる。さらに、蓋体６７に第１吸収部材７０Ｆの貫通孔７０ａに入るように箱状をなすとともに解除方向に向けて開口する突出部６７ｂを凹設すると、第１吸収部材７０Ｆの移動をより抑制することができる。なお、図１１においては、シート２９の本体部分、支持部材２７及び収容部材２８の図示を省略している。 As shown in FIG. 11, the insertion protrusion 67d that can be inserted into the notch 70d of the first absorbent member 70F is provided on the lid 67 so that the lid 67 is attached in such a manner that the insertion protrusion 67d is inserted into the notch 70d. With this, the movement of the shielding sheet 71 and the first absorbing member 70F can be suppressed. Further, if a protrusion 67b having a box shape and opening in the releasing direction is formed in the lid 67 so as to enter the through hole 70a of the first absorbing member 70F, the movement of the first absorbing member 70F is further suppressed. be able to. Note that, in FIG. 11, the main body portion of the seat 29, the support member 27, and the housing member 28 are not shown.
図１２に二点鎖線で示すように、廃液収容体６０が挿入方向Ｎに移動して装着室４１に入ると、装着室４１に突出する廃液伝達部４８は、廃液収容体６０に設けられた箱状の突出部６７ｂの中（凹部の中）に入る。そして、廃液収容体６０が装着室４１内で接続方向Ｍに移動して図１２に実線で示す位置に至ると、廃液伝達部４８が突出部６７ｂの開口から出て廃液導入口６７ａに入り、第１吸収部材７０Ｆに接触する。 As shown by the chain double-dashed line in FIG. 12, when the waste liquid container 60 moves in the insertion direction N and enters the mounting chamber 41, the waste liquid transfer portion 48 protruding into the mounting chamber 41 is provided in the waste liquid container 60. It enters into the box-shaped protrusion 67b (in the recess). Then, when the waste liquid container 60 moves in the connection direction M in the mounting chamber 41 to reach the position shown by the solid line in FIG. 12, the waste liquid transfer portion 48 comes out of the opening of the projecting portion 67b and enters the waste liquid inlet 67a, It contacts the first absorbing member 70F.
すなわち、第１吸収部材７０Ｆは、装着室４１内における接続方向Ｍへの移動に伴って廃液伝達部４８と接触する。これにより、液体噴射ヘッド３１が噴射した液体を廃液受容部３０が廃液として受容した場合には、その噴射廃液が廃液伝達部４８を伝って廃液収容体６０に収容される。 That is, the first absorbing member 70F comes into contact with the waste liquid transmitting portion 48 as the first absorbing member 70F moves in the connecting direction M in the mounting chamber 41. As a result, when the liquid ejected by the liquid ejecting head 31 is received by the waste liquid receiving unit 30 as the waste liquid, the ejected waste liquid is stored in the waste liquid container 60 along the waste liquid transmitting unit 48.
また、廃液収容体６０が装着室４１内で接続方向Ｍに移動すると、廃液導入部８１が排出部４２と接続される。すなわち、廃液導入部８１は、装着室４１内における接続方向Ｍへの移動に伴って、排出部４２と接続される。なお、廃液収容容器６１の内部に排出部４２が挿入された場合に、排出部４２の周囲及びその下方に廃液が流れる空間を空けておくために、下層に位置する第２吸収部材７０Ｓに切り欠き７０ｆを設けておくとよい。 When the waste liquid container 60 moves in the connecting direction M in the mounting chamber 41, the waste liquid introducing portion 81 is connected to the discharging portion 42. That is, the waste liquid introduction part 81 is connected to the discharge part 42 as the waste liquid introduction part 81 moves in the connection direction M in the mounting chamber 41. When the discharge part 42 is inserted into the waste liquid storage container 61, in order to leave a space for the waste liquid to flow around and below the discharge part 42, the second absorption member 70S located in the lower layer is cut. It is advisable to provide the notch 70f.
図１３に示すように、接続端子８２ａを有する回路基板８２は、廃液収容容器６１の接続方向Ｍに延びる側壁６３に形成された凹部８３内に設けられ、装着室４１内における接続方向Ｍへの移動に伴って基板接続部４３と電気的に接続される。これにより、回路基板８２と制御部１００（図３参照）との間で、廃液等に関する情報が授受される。 As shown in FIG. 13, the circuit board 82 having the connection terminals 82 a is provided in the recess 83 formed in the side wall 63 extending in the connection direction M of the waste liquid storage container 61, and is connected to the connection direction M in the mounting chamber 41. It is electrically connected to the board connecting portion 43 as it moves. As a result, information regarding waste liquid and the like is exchanged between the circuit board 82 and the control unit 100 (see FIG. 3).
廃液収容容器６１は、装着室４１内で接続方向Ｍに移動したときに係止部４９と係合する係合部８９を有することが好ましい。係合部８９は、例えば、廃液収容室６１ａの天井部分を構成する蓋体６７に形成される凹凸形状からなる（図１４を併せて参照）。 The waste liquid storage container 61 preferably has an engagement portion 89 that engages with the locking portion 49 when the waste liquid storage container 61 moves in the connection direction M in the mounting chamber 41. The engagement portion 89 has, for example, an uneven shape formed on the lid 67 that forms the ceiling portion of the waste liquid storage chamber 61a (see also FIG. 14).
廃液収容容器６１には、接続方向Ｍへの移動時に案内突部４７に案内される案内部８７を設けることが好ましい（図１４を併せて参照）。本実施形態の案内部８７は、壁部６５に設けた凹部であるが、底壁６２、側壁６３，６４または蓋体６７に設けた凹部、凸部または平面を案内部８７としてもよい。 It is preferable to provide the waste liquid container 61 with a guide portion 87 that is guided by the guide protrusion 47 when moving in the connection direction M (see also FIG. 14). Although the guide portion 87 of the present embodiment is a concave portion provided in the wall portion 65, the concave portion, the convex portion or the flat surface provided in the bottom wall 62, the side walls 63, 64 or the lid 67 may be used as the guide portion 87.
廃液収容容器６１において、底壁６２及び壁部６５が延びる方向を幅方向Ｗとすると、廃液導入部８１は、幅方向Ｗにおいて案内部８７と係合部８９の間に配置することが好ましい。 In the waste liquid container 61, when the direction in which the bottom wall 62 and the wall portion 65 extend is the width direction W, the waste liquid introducing portion 81 is preferably arranged between the guide portion 87 and the engaging portion 89 in the width direction W.
図１４及び図１５に示すように、廃液収容容器６１において、廃液導入部８１、接続端子８２ａ及び案内部８７は、底壁６２に沿って延びる仮想平面Ｐと重なる位置に配置することが好ましい。すなわち、底壁６２から蓋体６７に向かう方向の長さを高さとすると、廃液導入部８１、接続端子８２ａ及び案内部８７は同程度の高さに設定し、図１５に示す正面視において、廃液導入部８１、接続端子８２ａ及び案内部８７が幅方向Ｗに並ぶようにするとよい。 As shown in FIGS. 14 and 15, in the waste liquid storage container 61, it is preferable that the waste liquid introducing portion 81, the connection terminal 82a, and the guide portion 87 are arranged at positions overlapping the virtual plane P extending along the bottom wall 62. That is, when the length in the direction from the bottom wall 62 to the lid 67 is height, the waste liquid introducing portion 81, the connection terminal 82a, and the guide portion 87 are set to the same height, and in the front view shown in FIG. The waste liquid introducing portion 81, the connection terminal 82a, and the guide portion 87 may be arranged side by side in the width direction W.
特に、案内突部４７（図１３参照）が凹部からなる案内部８７の上端と対応する位置で係合する場合、案内突部４７に案内部８７が係合することによって、廃液収容体６０の高さ方向の位置決めがなされるので、装着時における廃液導入部８１及び接続端子８２ａの位置を正しく設定することができる。 Particularly, when the guide protrusion 47 (see FIG. 13) engages with the upper end of the guide portion 87 formed of a recess at a position corresponding to the guide protrusion 87, the guide portion 87 engages with the guide protrusion 47, whereby the waste liquid container 60 Since the positioning in the height direction is performed, the positions of the waste liquid introducing portion 81 and the connection terminal 82a at the time of mounting can be set correctly.
また、図１５に示すように、廃液収容容器６１において、接続端子８２ａを底壁６２と係合部８９の間に配置すると、接続端子８２ａの高さ方向の位置決めをより正確にすることができるので、好ましい。 Further, as shown in FIG. 15, when the connection terminal 82a is arranged between the bottom wall 62 and the engaging portion 89 in the waste liquid container 61, the connection terminal 82a can be positioned more accurately in the height direction. Therefore, it is preferable.
図１６に示すように、手掛部６６ａは、底壁６２から解除方向に延設する態様で、壁部６６に突設することが好ましい。このようにすると、底壁６２を下にして載置する場合に廃液収容体６０の姿勢を安定させることができるので、廃液を収容した状態で取り出した場合に、蓋体６７に開口する廃液導入口６７ａや壁部６５に開口する廃液導入部８１からの廃液の漏出を抑制することができる。また、底壁６２に近い位置に手掛部６６ａを設けることによって、手掛部６６ａがない天側（蓋体６７側）と手掛部６６ａがある底側（底壁６２）側とを容易に区別することができる。 As shown in FIG. 16, it is preferable that the handle portion 66 a be provided so as to project from the wall portion 66 in a manner extending from the bottom wall 62 in the releasing direction. By doing so, the posture of the waste liquid container 60 can be stabilized when the waste liquid container 60 is placed with the bottom wall 62 facing down, and therefore, when the waste liquid is taken out in the housed state, the waste liquid introduction opening to the lid 67 is introduced. It is possible to suppress the leakage of the waste liquid from the waste liquid introducing portion 81 that opens to the opening 67a and the wall portion 65. Further, by providing the handle 66a at a position close to the bottom wall 62, the top side (lid 67 side) without the handle 66a and the bottom side (bottom wall 62) side with the handle 66a are easily provided. Can be distinguished.
さらに、図３、図４及び図１２に示すように、装着室４１に段部４１ａを設けておくと、廃液収容体６０の天側と底側とを逆にした状態では、手掛部６６ａが段部４１ａに引っかかるので、装着室４１への入れ間違いを防ぐことができる。 Further, as shown in FIGS. 3, 4 and 12, when the mounting chamber 41 is provided with the stepped portion 41a, when the waste liquid container 60 is turned upside down and the bottom side is turned upside down, the handle portion 66a is turned on. Is caught on the stepped portion 41a, so that it is possible to prevent the mistaken insertion into the mounting chamber 41.
次に、以上のように構成された廃液収容体６０及び液体噴射装置１１の作用について説明する。
廃液収容体６０においては、遮蔽シート７１で廃液収容室６１ａ内を仕切ることにより、吸引廃液が上層の第１吸収部材７０Ｆに吸収されるのを抑制して、吸引廃液を下層の第２吸収部材７０Ｓに優先的に吸収させることができる。また、第１吸収部材７０Ｆの自重による沈下を遮蔽シート７１が抑制することにより、廃液伝達部４８の第１吸収部材７０Ｆに対する接触面積を安定して確保することができる。
Next, the operation of the waste liquid container 60 and the liquid ejecting apparatus 11 configured as described above will be described.
In the waste liquid container 60, by partitioning the inside of the waste liquid storage chamber 61a with the shielding sheet 71, the suction waste liquid is suppressed from being absorbed by the upper first absorbing member 70F, and the suction waste liquid is absorbed by the lower second absorbing member. 70S can be absorbed preferentially. Further, since the shielding sheet 71 suppresses the subsidence of the first absorbent member 70F due to its own weight, the contact area of the waste liquid transfer part 48 with the first absorbent member 70F can be stably ensured.
ここで、液体噴射装置１１において廃液収容体６０を収容する装着室４１は、筐体１２の底面側に向けて開口するので、筐体１２をひっくり返して廃液収容体６０を着脱することになる。そして、廃液収容体６０には、廃液導入口６７ａ及び廃液導入部８１が開口するので、廃液収容体６０を装着した状態で筐体１２をひっくり返すと、廃液導入口６７ａまたは廃液導入部８１が下（または斜め下）を向いてしまうおそれがある。その点、廃液収容体６０に収容した廃液を吸収部材７０に吸収しておくことによって、廃液導入口６７ａ及び廃液導入部８１からの廃液の漏出が抑制される。 Here, since the mounting chamber 41 that accommodates the waste liquid container 60 in the liquid ejecting apparatus 11 opens toward the bottom surface side of the housing 12, the housing 12 is turned over and the waste liquid container 60 is attached and detached. .. Since the waste liquid container 60 has the waste liquid inlet 67a and the waste liquid introducing portion 81, when the housing 12 is turned over with the waste liquid container 60 attached, the waste liquid inlet 67a or the waste liquid introducing portion 81 is lowered. There is a risk of facing (or diagonally below). In this regard, by absorbing the waste liquid stored in the waste liquid storage body 60 by the absorbing member 70, leakage of the waste liquid from the waste liquid introduction port 67a and the waste liquid introduction portion 81 is suppressed.
なお、廃液導入口６７ａは複数有り、また、廃液導入部８１を出入りさせるために開口面積をある程度広く確保する必要があるため、特に廃液が漏出しやすい。その点、本実施形態では、廃液導入部８１が出入りする凹部（貫通孔７０ａ）を箱状の突出部６７ｂで覆っているので、廃液導入口６７ａの開口面積が小さくなり、廃液の漏出が抑制される。 Since there are a plurality of waste liquid introducing ports 67a and it is necessary to secure a large opening area to allow the waste liquid introducing portion 81 to move in and out, the waste liquid is particularly likely to leak. In this respect, in the present embodiment, since the concave portion (through hole 70a) through which the waste liquid introducing portion 81 enters and exits is covered with the box-shaped protruding portion 67b, the opening area of the waste liquid introducing port 67a becomes small, and the leakage of the waste liquid is suppressed. To be done.
また、廃液収容体６０においては、廃液受容部３０が受容した噴射廃液を廃液伝達部４８に伝わせて、廃液伝達部４８に接触する第１吸収部材７０Ｆに吸収させるので、装着室４１内における廃液の飛散が抑制される。そのため、接続端子８２ａや装着室４１の内壁等に廃液が付着しにくい。また、回路基板８２は凹部８３内に収容されているので、仮に漏出した廃液が側壁６３を伝い落ちたとしても、接続端子８２ａに廃液が付着しにくい。 Further, in the waste liquid container 60, the ejected waste liquid received by the waste liquid receiving portion 30 is transmitted to the waste liquid transmitting portion 48 and is absorbed by the first absorbing member 70F which is in contact with the waste liquid transmitting portion 48, so that in the mounting chamber 41. The scattering of waste liquid is suppressed. Therefore, the waste liquid is unlikely to adhere to the connection terminal 82a, the inner wall of the mounting chamber 41, or the like. Further, since the circuit board 82 is housed in the recess 83, even if the leaked waste liquid travels down the side wall 63, the waste liquid is unlikely to adhere to the connection terminals 82a.
なお、スライダー５０を付勢部材５２によって解除方向に付勢しておくと、装着室４１内で接続方向Ｍに移動する廃液収容体６０内の第１吸収部材７０Ｆに廃液伝達部４８が押し付けられる。そのため、廃液伝達部４８と第１吸収部材７０Ｆを確実に接触させることができる。 When the slider 50 is urged in the releasing direction by the urging member 52, the waste liquid transfer portion 48 is pressed against the first absorbing member 70F in the waste liquid container 60 moving in the connecting direction M in the mounting chamber 41. .. Therefore, the waste liquid transfer part 48 and the first absorbing member 70F can be surely brought into contact with each other.
装着室４１内で接続方向Ｍに移動した廃液収容体６０は、係止部４９が係合部８９に引っかかることによって、液体噴射装置１１に装着された状態が維持される。
ここで、装着室４１において幅方向Ｗにスペースの余裕があると、廃液収容体６０が係合部８９を中心に傾いてしまうおそれがあるが、案内部８７を案内突部４７と係合させておくことにより、廃液収容体６０の傾きを抑制することができる。
The waste liquid container 60 that has moved in the connection direction M in the mounting chamber 41 is maintained in the state of being mounted on the liquid ejecting apparatus 11 by the locking portion 49 being caught by the engaging portion 89.
Here, if there is a space in the mounting chamber 41 in the width direction W, the waste liquid container 60 may tilt around the engaging portion 89, but the guide portion 87 is engaged with the guide protrusion 47. The inclination of the waste liquid container 60 can be suppressed by keeping it.
そして、幅方向Ｗにおいて案内部８７と係合部８９の間に廃液導入部８１を配置しておくことによって、廃液収容体６０の傾き等に起因する廃液導入部８１の変位が抑制される。これにより、廃液導入部８１の排出部４２に対する接続を維持して、廃液の漏出を抑制することができる。また、接続端子８２ａを底壁６２と係合部８９の間に配置しておくことによって、廃液収容体６０の傾き等に起因する接続端子８２ａの変位が抑制されるので、接続端子８２ａの基板接続部４３に対する接続を維持することができる。 By disposing the waste liquid introducing portion 81 between the guide portion 87 and the engaging portion 89 in the width direction W, the displacement of the waste liquid introducing portion 81 due to the inclination of the waste liquid container 60 and the like is suppressed. Thereby, the connection of the waste liquid introduction part 81 to the discharge part 42 can be maintained, and the leakage of the waste liquid can be suppressed. Further, by disposing the connection terminal 82a between the bottom wall 62 and the engagement portion 89, displacement of the connection terminal 82a due to the inclination of the waste liquid container 60 or the like is suppressed, and thus the substrate of the connection terminal 82a. The connection to the connecting portion 43 can be maintained.
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。
廃液収容体６０を液体噴射装置１１に対して着脱可能に装着することにより、筐体１２内に交換できない固定式の廃液収容部を設けるよりも、廃液を収容するためのスペース（装着室４１）を小さくすることが可能になる。これにより、液体噴射装置１１を小型化することができる。
According to the above embodiment, the following effects can be obtained.
