Description

本願は、インクジェット印刷の技術分野に関し、特に、インクカートリッジに関するものである。 The present application relates to the technical field of inkjet printing, and more particularly to an ink cartridge.

図１及び図２に示すように、関連技術においては、プリンタには、インクカートリッジ３を装着するための装着部２が設けられており、装着部２は、貫通孔２１７及び底面２１等を有する。底面２１には、インクカートリッジ３のインク供給口に接続するインク供給管が設けられており、インクカートリッジ３の最も下側の端部は底面２１に当接する。貫通孔２１７は、底面２１に設けられている。インクカートリッジ３は、ケース３１と、チップ３２と、弾性部材３３と、回転レバー３４とを有する。回転レバー３４は、操作部３１５と、回転軸３１６と、係合部３１７とを備える。インクカートリッジ２を装着部２から離脱させようとする際に、操作者は、操作部３１５を押圧することにより、回転レバー３４の上部を方向ｆに沿って回転させ、係合部３１７を貫通孔２１７から離脱させ、これにより、インクカートリッジ３を取り出す動作が完了する。 As shown in FIGS. 1 and 2, in the related art, the printer is provided with a mounting portion 2 for mounting the ink cartridge 3, and the mounting portion 2 has a through hole 217, a bottom surface 21 and the like. . An ink supply pipe connected to the ink supply port of the ink cartridge 3 is provided on the bottom surface 21, and the lowermost end portion of the ink cartridge 3 abuts on the bottom surface 21. The through hole 217 is provided in the bottom surface 21. The ink cartridge 3 includes a case 31, a chip 32, an elastic member 33, and a rotation lever 34. The rotation lever 34 includes an operation unit 315, a rotation shaft 316, and an engagement unit 317. When trying to detach the ink cartridge 2 from the mounting portion 2, the operator presses the operation portion 315 to rotate the upper portion of the rotation lever 34 along the direction f, thereby causing the engagement portion 317 to pass through the through hole. Thus, the operation of removing the ink cartridge 3 is completed.

然しながら、図２は、インクカートリッジ３と装着部２が係合された模式図であり、底面２１の底辺２１１と貫通孔２１７の第１の側面２１７１とが交差する領域は、領域Ｑである。第１の側面２１７１に対向する表面は、第２の側面２１７２である。インクカートリッジ３が装着部２に維持される必要がある場合、底辺２１１、第１の側面２１７１及び領域Ｑにより被係合部βが形成されている。インクカートリッジ３が装着部２に維持される必要があり、インクカートリッジ３が装着部２に密着して固定される必要があるため、係合部３１７は、インクカートリッジ３と装着部２との間の分離力に対抗する必要がある。従って、インクカートリッジ３が装着部２に装着されている場合、係合部３１７と被係合部βとの間には、互いに圧縮される状態にある。インクカートリッジ３を装着部２から取り出す中、操作部３１５が押圧されると、操作部３１５は、方向ｆに沿って回転し、係合部３１７は、方向−ｆに沿って回転し、この場合、係合部３１７は、１つの−Ｐ方向の変位量及び１つの＋Ｗ方向の変位量を同時に発生する。その＋Ｗ方向の変位量により、実際に、係合部３１７を被係合部βにさらに接近させることで、係合部３１７と被係合部βとの間の互いに圧縮される状態を増加させる。この場合、係合部３１７がさらに−Ｐ方向に沿って移動すると、係合部３１７と領域Ｑとの間の摩擦力を増加させる。この被係合部β接近する変位量が存在しているため、係合部３１７と被係合部βとの間の相互摩擦を増加させる。装着部２は、一定の使用期間の後、被係合部βが摩損され、特に、領域Ｑが摩損されることで、インクカートリッジ３と装着部２との間の固定に影響を与える。 However, FIG. 2 is a schematic diagram in which the ink cartridge 3 and the mounting portion 2 are engaged, and a region where the bottom side 211 of the bottom surface 21 intersects the first side surface 2171 of the through hole 217 is a region Q. The surface facing the first side surface 2171 is the second side surface 2172. When the ink cartridge 3 needs to be maintained in the mounting portion 2, the engaged portion β is formed by the base 211, the first side surface 2171, and the region Q. Since the ink cartridge 3 needs to be maintained in the mounting portion 2 and the ink cartridge 3 needs to be fixed in close contact with the mounting portion 2, the engaging portion 317 is provided between the ink cartridge 3 and the mounting portion 2. It is necessary to counter the separation power. Therefore, when the ink cartridge 3 is mounted on the mounting portion 2, the engaging portion 317 and the engaged portion β are in a state of being compressed with each other. When the operation unit 315 is pressed while taking out the ink cartridge 3 from the mounting unit 2, the operation unit 315 rotates along the direction f, and the engagement unit 317 rotates along the direction -f. The engaging portion 317 simultaneously generates one displacement amount in the −P direction and one displacement amount in the + W direction. Due to the amount of displacement in the + W direction, the engagement portion 317 is actually brought closer to the engaged portion β, thereby increasing the compressed state between the engagement portion 317 and the engaged portion β. . In this case, when the engaging portion 317 further moves along the −P direction, the frictional force between the engaging portion 317 and the region Q is increased. Since there is a displacement amount that approaches the engaged portion β, the mutual friction between the engaging portion 317 and the engaged portion β is increased. The mounting portion 2 affects the fixation between the ink cartridge 3 and the mounting portion 2 because the engaged portion β is worn away after a certain period of use, and particularly the region Q is worn away.

本願の実施例は、従来のインクカートリッジにおいて係合部と被係合部との間の摩損によりインクカートリッジと装着部との間の固定に影響を与えるという課題を解決するために、以下のインクカートリッジを提供している。 In order to solve the problem that the fixing between the ink cartridge and the mounting portion is affected by the wear between the engaging portion and the engaged portion in the conventional ink cartridge, the embodiment of the present application is designed to solve the following ink.

図５に示すように、インクカートリッジ４は、装着部２と嵌合されており、装着部２は、底面２１と、底辺２１１と、貫通孔２１７と、インク供給管２５とを備える。貫通孔２１７は、第１の側面２１７１と、第２の側面２１７２とを備え、第１の側面２１７１と第２の側面２１７２とは対向している。 As shown in FIG. 5, the ink cartridge 4 is fitted to the mounting portion 2, and the mounting portion 2 includes a bottom surface 21, a bottom side 211, a through hole 217, and an ink supply pipe 25. The through-hole 217 includes a first side surface 2171 and a second side surface 2172, and the first side surface 2171 and the second side surface 2172 are opposed to each other.

可動部材４２は、収容空間に取り付けられており、可動部材４２は、係止解除方向に平行する方向に沿って移動することができる。係止解除方向は、係合部４２３が被係合部βから離れる方向である。本実施例においては、係止解除方向は、Ｐ軸に平行し、具体的に、係止解除方向は、−Ｐ方向である。 The movable member 42 is attached to the accommodation space, and the movable member 42 can move along a direction parallel to the locking release direction. The locking release direction is a direction in which the engaging portion 423 is separated from the engaged portion β. In this embodiment, the unlocking direction is parallel to the P axis, and specifically, the unlocking direction is the -P direction.

インクカートリッジ４は、装着部２に維持される必要があり、インクカートリッジ４は装着部２と密着して固定される必要がある。インクカートリッジ４が装着部２に装着された時、液体流出口４５は、インク供給管２５と連結され、係合部４２３は、貫通孔２１７と嵌合される。被係合部βは、底辺２１１及び第１の側面２１７１とされる。係合部４２３は、前記被係合部βと係合可能にされる。インクカートリッジを取り出す必要がある時に、操作者は、受力部４２１（受力部４２１が上端面４１a又はケース４１から突出している）に付勢することにより、可動部材４２は、操作者により付勢された力を受けると、移動制限部４２２は、弾性部材４３を圧縮し、可動部材４２は、−Ｐ方向へ移動し（即ち、可動部材４２は、収容空間において係止解除方向に沿って移動する）、係合部４２３は、−Ｐ方向に沿って移動し、係合部４２３が被係合部βから離脱され、係合部４２３と被係合部βとが係合解除され、インクカートリッジ４がポップアップされ、これにより、インクカートリッジ４を取り出す動作が完了する。 The ink cartridge 4 needs to be maintained in the mounting portion 2, and the ink cartridge 4 needs to be fixed in close contact with the mounting portion 2. When the ink cartridge 4 is attached to the attachment portion 2, the liquid outlet 45 is connected to the ink supply pipe 25, and the engagement portion 423 is fitted to the through hole 217. The engaged portion β is a bottom side 211 and a first side surface 2171. The engaging portion 423 can be engaged with the engaged portion β. When it is necessary to take out the ink cartridge, the operator urges the force receiving portion 421 (the force receiving portion 421 protrudes from the upper end surface 41a or the case 41), so that the movable member 42 is attached by the operator. When the urging force is received, the movement restricting unit 422 compresses the elastic member 43 and the movable member 42 moves in the −P direction (that is, the movable member 42 moves along the unlocking direction in the accommodation space. The engagement portion 423 moves along the −P direction, the engagement portion 423 is disengaged from the engaged portion β, the engagement portion 423 and the engaged portion β are disengaged, The ink cartridge 4 is popped up, whereby the operation for taking out the ink cartridge 4 is completed.

インクカートリッジ４が装着部２に装着された場合、弾性部材４３は、可動部材４２に係止解除方向と逆方向の力を付勢することができる。これにより、係合部４２３と被係合部βとが安定して係止されている。 When the ink cartridge 4 is mounted on the mounting portion 2, the elastic member 43 can urge the movable member 42 with a force in the direction opposite to the unlocking direction. As a result, the engaging portion 423 and the engaged portion β are stably locked.

インクカートリッジが取り出され、即ち、インクカートリッジ４が装着部２から離脱される中、係合部４２３は、−Ｐ方向に沿って移動して変位し、即ち、第１の面４１２１及び第２の面４１２２は、下端面４６に平行し、Ｐ軸は、下端面に平行し、係合部４２３は、移動制限部４２２の制限により−Ｐ方向（−Ｐ方向は、本実施例における係止解除方向であり、係合部４２３が被係合部βから離れる方向でもある）のみに移動できるため、インクカートリッジ４が装着部２から離脱される中、係合部４２３は、係止解除方向（本実施例において、−Ｐ方向である）に平行する方向に沿って変位し、当該変位は、被係合部βに向かう変位量を発生することがなく、当該変位は、Ｐ軸及びＷ軸において被係合部βに向かう投影変位量を発生することがないことで、係合部４２３の移動により係合部４２３と被係合部βとの間の摩擦力が増加することがなく、係合部４２３が移動した後、被係合部βに向かう変位量を発生することがなく、−Ｐ方向において被係合部βの変位量を発生することができる。従って、背景技術において回転レバーの回転による技術問題を解決することができ（即ち、インクカートリッジが取り出される中、被係合部βの摩損を回避した）、インクカートリッジ４と装着部２が安定して固定されることができる。 While the ink cartridge is taken out, that is, when the ink cartridge 4 is detached from the mounting portion 2, the engaging portion 423 moves and displaces along the −P direction, that is, the first surface 4121 and the second surface The surface 4122 is parallel to the lower end surface 46, the P-axis is parallel to the lower end surface, and the engaging portion 423 is in the −P direction (the −P direction is unlocked in this embodiment) due to the restriction of the movement restricting portion 422. The engaging portion 423 can move only in the direction away from the engaged portion β), so that the engaging portion 423 is released from the locking release direction (when the ink cartridge 4 is detached from the mounting portion 2). In this embodiment, it is displaced along a direction parallel to the −P direction), and the displacement does not generate a displacement amount toward the engaged portion β. Generating a projected displacement amount toward the engaged portion β in FIG. Therefore, the frictional force between the engaging portion 423 and the engaged portion β is not increased by the movement of the engaging portion 423, and after the engaging portion 423 moves, the engaged portion β is moved to the engaged portion β. The amount of displacement of the engaged portion β can be generated in the −P direction without generating the amount of displacement toward it. Therefore, the technical problem due to the rotation of the rotary lever can be solved in the background art (that is, the worn portion β is prevented from being worn while the ink cartridge is taken out), and the ink cartridge 4 and the mounting portion 2 are stabilized. Can be fixed.

係合部４２３は、被係合部βから離れる−Ｐ方向において、可動部材４２を液体流出口４５へ移動させる方向の変位量を発生することができる。 The engaging portion 423 can generate a displacement amount in the direction of moving the movable member 42 to the liquid outlet 45 in the −P direction away from the engaged portion β.

変形例
図６a及び図６ｃは何れも実施例１の変形例であり、これらの３つの変形例において、チップ４４は、傾けて設置されることなく、垂直に設置されても良く（図６aに示すように）、水平に設置されても良く（図６ｂに示すように）、又は、図６cのように、傾斜面に垂直に設置されてもよい。 Modifications FIGS. 6a and 6c are all modifications of the first embodiment. In these three modifications, the chip 44 may be installed vertically without being inclined (see FIG. 6a). As shown), may be installed horizontally (as shown in FIG. 6b), or may be installed perpendicular to the ramp, as in FIG. 6c.

図６ｄは、実施例１のもう1つの変形例であり、当該変形例において、第１の面４１２１、第２の面４１２２は、装着部２の底面２１に平行しない又は下端面４６に平行しない。より好ましくは、図６ｄに示すように、第２の収容空間４１２は、第１の面４１２１と、第２の面４１２２と、第３の面４１２３とを備える。第１の面４１２１及び第３の面４１２３により、移動制限部４２２の移動が制限される。移動制限部４２２は、＋Ｔ方向（＋Ｔ方向はＰ軸及びＷ軸に交差し、且つＰ軸及びＷ軸からなる平面に平行し、−Ｐ方向及び−Ｗ方向へ斜めに延在する）に沿って移動することができる。本変形例における係止解除方向（係合部４２３が被係合部βから離れる方向でもある）は、＋Ｔ方向であり、Ｐ軸及びＷ軸に交差し、さらに、係止解除方向は、−Ｐ方向、−Ｗ方向に延在する方向である。インクカートリッジ４が取り出され、即ち、インクカートリッジ４が装着部２から離脱される中、係合部４２３は、斜め下方（＋Ｔ方向）へ移動するものであり、移動制限部４２２は、第１の面４１２１及び第３の面４１２３に平行する＋Ｔ方向に沿って移動するものである。即ち、可動部材４２は、係止解除中、−Ｐ方向と−Ｐ方向に垂直な−Ｗ方向との両方向において一定の変位量を有する。インクカートリッジ４が装着部２から離脱される中、係合部４２３は、係止解除方向（本実施例において、＋Ｔ方向）に平行する方向において、変位を発生する。当該変位は、被係合部βに向かう変位量を発生することがなく、当該変位は、Ｐ軸及びＷ軸において被係合部βに向かう投影変位量を発生することがなく、且つ−Ｐ方向及び−Ｗ方向において被係合部βの変位量を発生することができる。従って、係合部４２３が被係合部βから即座に離脱されることができるため、尚更、背景技術における技術問題が生じない。係合部４２３は、被係合部βから離れる−Ｐ方向及び−Ｗ方向において、可動部材４２を液体流出口４５に向かう−Ｐ方向の変位量及び−Ｗ方向の変位量を発生することができる。 FIG. 6 d is another modification of the first embodiment, and in this modification, the first surface 4121 and the second surface 4122 are not parallel to the bottom surface 21 of the mounting portion 2 or parallel to the lower end surface 46. . More preferably, as shown in FIG. 6 d, the second accommodation space 412 includes a first surface 4121, a second surface 4122, and a third surface 4123. The movement of the movement restriction unit 422 is restricted by the first surface 4121 and the third surface 4123. The movement restriction unit 422 is along the + T direction (the + T direction intersects the P axis and the W axis, is parallel to the plane formed by the P axis and the W axis, and extends obliquely in the −P direction and the −W direction). Can move. The unlocking direction (which is also the direction in which the engaging portion 423 is separated from the engaged portion β) in the present modification is the + T direction, intersects the P axis and the W axis, and the unlocking direction is − This is a direction extending in the P direction and the −W direction. While the ink cartridge 4 is taken out, that is, while the ink cartridge 4 is detached from the mounting portion 2, the engaging portion 423 moves obliquely downward (+ T direction), and the movement restricting portion 422 It moves along the + T direction parallel to the surface 4121 and the third surface 4123. In other words, the movable member 42 has a certain amount of displacement in both the −P direction and the −W direction perpendicular to the −P direction during unlocking. While the ink cartridge 4 is detached from the mounting portion 2, the engaging portion 423 generates displacement in a direction parallel to the unlocking direction (in the present embodiment, the + T direction). The displacement does not generate a displacement amount toward the engaged portion β, the displacement does not generate a projected displacement amount toward the engaged portion β on the P axis and the W axis, and −P The amount of displacement of the engaged portion β can be generated in the direction and the −W direction. Therefore, since the engaging portion 423 can be immediately detached from the engaged portion β, a technical problem in the background art does not occur. The engaging portion 423 generates a displacement amount in the −P direction and a displacement amount in the −W direction toward the liquid outlet 45 in the −P direction and the −W direction away from the engaged portion β. it can.

本変形例においては、第１の面４１２１及び第２の面４１２２は、互いに平行する湾曲面であっても良く、移動制限部４２２は、第１の面４１２１と第２の面４１２２との間に取り付けられている。 In the present modification, the first surface 4121 and the second surface 4122 may be curved surfaces that are parallel to each other, and the movement restricting portion 422 is between the first surface 4121 and the second surface 4122. Is attached.

図６ｅは、実施例１のもう１つの変形例であり、当該変形例において、受力部４２１は、可動部材４２の上側に位置し、操作者がＰ軸に平行する力を付勢すると、可動部材４２は、−Ｐ方向に沿って移動し、インクカートリッジ４が取り出された。 FIG. 6e is another modification of the first embodiment. In this modification, the force receiving portion 421 is positioned on the upper side of the movable member 42, and when the operator urges a force parallel to the P axis, The movable member 42 moved along the −P direction, and the ink cartridge 4 was taken out.

図７は、実施例２に関わる模式図である。実施例２と実施例１との相違は、
１．移動制限部４２２は、可動部材４２のほぼ中央位置に設けられており、この構造により、可動部材４２がより均一に受力されて、より安定して移動することができること、
２．受力部４２１は、インクカートリッジの第３の表面４１ｃから突出するように配置されていること、にある。 Example 2
FIG. 7 is a schematic diagram related to the second embodiment. The difference between Example 2 and Example 1 is
1. The movement restricting portion 422 is provided at a substantially central position of the movable member 42. With this structure, the movable member 42 is more uniformly received and can move more stably.
2. The force receiving portion 421 is disposed so as to protrude from the third surface 41c of the ink cartridge.

実施例３
図８は、実施例３に関連する模式図である。実施例３と実施例２との相違は、インクカートリッジは、固定部４１３を更に有し、可動部材４２は、溝部４２５（収容溝部４２５とも称する）を有することにある。固定部４１３は、収容空間に固定されて溝部４２５に挿し込まれて、可動部材４２は、係止解除方向に沿って相対移動することができる。溝部４２５は、ケース４１における固定部４１３を収容するために用いられる。可動部材４２とケース４１とが組立てられる際に、固定部４１３は、溝部４２５に取り付けられる。固定部４１３と溝部４２５の壁部との間には、弾性部材４３が配置されており、即ち、弾性部材４３が溝部４２５に設けられており、弾性部材４３は、一端部が固定部４１３に当接し、他端部が溝部４２５に当接し、受力部４２１が受力されると、固定部４１３と溝部４２５は、係止解除方向に平行する方向に沿って相対移動することができ（本実施例において、係止解除方向は、−Ｐ方向である）、溝部４２５の壁部は、固定部４１３に沿って移動する。これにより、係合部４２３は、装着部２における被係合部βから離脱される。 Example 3
FIG. 8 is a schematic diagram related to the third embodiment. The difference between the third embodiment and the second embodiment is that the ink cartridge further includes a fixed portion 413, and the movable member 42 has a groove portion 425 (also referred to as an accommodation groove portion 425). The fixed portion 413 is fixed in the accommodation space and inserted into the groove portion 425, and the movable member 42 can relatively move along the locking release direction. The groove portion 425 is used for accommodating the fixing portion 413 in the case 41. When the movable member 42 and the case 41 are assembled, the fixed portion 413 is attached to the groove portion 425. The elastic member 43 is disposed between the fixing portion 413 and the wall portion of the groove portion 425. That is, the elastic member 43 is provided in the groove portion 425, and one end portion of the elastic member 43 is connected to the fixing portion 413. When the other end is in contact with the groove 425 and the force receiving portion 421 is received, the fixing portion 413 and the groove 425 can move relative to each other in a direction parallel to the unlocking direction ( In this embodiment, the unlocking direction is the −P direction), and the wall portion of the groove portion 425 moves along the fixing portion 413. Thereby, the engaging part 423 is disengaged from the engaged part β in the mounting part 2.

溝部４２５の壁部と固定部４１３との形状は、可動部材４２の移動軌跡を決めた。溝部４２５の壁部は、Ｐ軸に平行して設けられてもよく、Ｐ軸に対して傾斜して設けられても良い（即ち、溝部４２５の壁部は、−Ｐ方向及び−Ｗ方向に沿って傾斜して設けられてもよい）。溝部４２５の壁部が傾斜して設けられる場合、可動部材４２は、溝部４２５により固定部４１３に沿って−Ｐ方向及び−Ｗ方向へ変位量を発生し、係合部４２３は、被係合部βから即座に離脱されることができる。溝部４２５は、可動部材４２全体を貫通する貫通溝部であっても良く、可動部材４２を貫通しなくても良い。 The shape of the wall portion of the groove portion 425 and the fixed portion 413 determined the movement locus of the movable member 42. The wall portion of the groove portion 425 may be provided in parallel to the P axis, or may be provided inclined with respect to the P axis (that is, the wall portion of the groove portion 425 is in the −P direction and the −W direction). May be provided along an inclination). When the wall portion of the groove portion 425 is provided to be inclined, the movable member 42 generates a displacement amount in the −P direction and the −W direction along the fixed portion 413 by the groove portion 425, and the engaging portion 423 is engaged. It is possible to leave the part β immediately. The groove portion 425 may be a through groove portion penetrating the entire movable member 42 or may not penetrate the movable member 42.

このように、インクカートリッジが取り出され、即ち、インクカートリッジ４が装着部２から離脱される中、操作者が受力部４２１に＋Ｐ方向の力を付勢すると、可動部材４２が弾性部材４３を圧縮し、可動部材４２が＋Ｐ方向に移動し、係合部４２３が被係合部βから離脱される。 In this manner, when the ink cartridge is removed, that is, while the ink cartridge 4 is detached from the mounting portion 2, when the operator urges the force receiving portion 421 in the + P direction, the movable member 42 moves the elastic member 43. Compressed, the movable member 42 moves in the + P direction, and the engaging portion 423 is disengaged from the engaged portion β.

本変形例では、＋Ｐ方向は、本実施例における係止解除方向であり、係合部４２３が被係合部βから離れる方向でもある。 In the present modification, the + P direction is a locking release direction in the present embodiment, and is also a direction in which the engaging portion 423 is separated from the engaged portion β.

係合部４２３は、被係合部βから離れる＋Ｐ方向において、可動部材４２を液体流出口４５から離れる方向へ移動させる変位量を発生することができる。 The engaging portion 423 can generate a displacement amount that moves the movable member 42 in the direction away from the liquid outlet 45 in the + P direction away from the engaged portion β.
