Specifically, the mounting surface 39 is gradually inclined upward in the + X and + Z axis directions, and the ends of the mounting surface 39 in the −X and −Z axis directions are the near ends 393, and the + X and + Z of the mounting surface 39 are The end in the axial direction is the far end 394. After the ink cartridge is attached to the mounting portion, the near end 393 is close to the ink cartridge, the far end 394 is far from the ink cartridge, and the far end 394 is higher than the near end 393 in the + Z-axis direction, that is, the far end 394 is located in the + Z-axis direction of the near end 393.

更に、図７にインクカートリッジが装着部に取付けらた構成の模式図を示す。図１を参照して見えるように、水平方向においてインクカートリッジが取付面３９にポインティングする方向が＋Ｘ軸方向であり、鉛直方向において上向きの方向が＋Ｚ軸方向であり、＋Ｘ軸方向と＋Ｚ軸方向との両方に直交する方向がＹ軸方向である。インクカートリッジは、ケース２を含み、図５〜９に示すように、ケース２が略直方体状を呈し、具体的には、実際のニーズによって、ケース２が楕円形や円形などの形状を呈してもようい。より具体的には、図５〜７に示すケース２は、６つの面により構成され、そのうち、第１面２ａと第２面２ｂとが相互に対向し、第３面２ｃと第４面２ｄとが相互に対向するとともに、第１面２ａに対して略垂直となる。より具体的には、ケース２がキャビティとカバーと（図示しない）を含むことは一般であり、キャビティにインクを貯留可能なインク室２５が設けられ、カバーがキャビティに溶接されることにより、インク室２５が密閉状態になることが可能である。   Further, FIG. 7 shows a schematic diagram of a configuration in which the ink cartridge is attached to the mounting portion. As can be seen with reference to FIG. 1, the direction in which the ink cartridge points to the mounting surface 39 in the horizontal direction is the + X-axis direction, the upward direction in the vertical direction is the + Z-axis direction, and the + X-axis direction and the + Z-axis direction The direction perpendicular to both of them is the Y-axis direction. The ink cartridge includes a case 2, and as shown in FIGS. 5 to 9, the case 2 has a substantially rectangular parallelepiped shape. Specifically, the case 2 has an elliptical shape or a circular shape depending on actual needs. Good morning. More specifically, the case 2 shown in FIGS. 5 to 7 is composed of six surfaces, of which the first surface 2a and the second surface 2b face each other, and the third surface 2c and the fourth surface 2d. Are opposed to each other and substantially perpendicular to the first surface 2a. More specifically, the case 2 generally includes a cavity and a cover (not shown). An ink chamber 25 capable of storing ink is provided in the cavity, and the cover is welded to the cavity. The chamber 25 can be sealed.

更に、第１面２ａにはインク供給口２１が設けられ、インク供給口２１とインク管３６とが密封に接続され、係合溝３７に対向するケース２の第４面２ｄに、係合部２２が設けられ、係合部２２が係合溝３７に係合する。ケース２の接触ピン３１に対向する位置にチップ２６がさらに設けられている。具体的には、図７に示すように、取付面３９が第２斜面３９２であり、チップ２６が、第１面２ａと第３面２ｃとの間に傾斜して設けられた斜面に設けられ、且つチップホルダに固定されており、チップ２６には、インク量情報や、インクのタイプ、製造メーカーなどの情報を記憶する記憶手段及び端子が設けられ、端子が装着部における接触ピン３１と電気的に連続されることが可能である。具体的には、第２斜面３９２と装着部との間に取付空間３９５が形成され、取付空間３９５の輪郭形状が、第２斜面３９２と装着部における第２斜面３９２に対向する対向面により形成されている。より具体的には、図７、９に示す対向面も傾斜する斜面であり、これに応じて、取付空間３９５が全体として傾斜する空間を呈す。取付空間３９５の上面は取付面３９である、即ち、取付空間３９５の上面の遠端３９４が近端３９３の＋Ｚ軸方向に位置する。いくつかの変化例では、取付面３９の傾斜角度が変化し、または対向面の形状が変化したことに伴って、取付空間３９５の輪郭形状も変化する。   Further, the first surface 2 a is provided with an ink supply port 21, the ink supply port 21 and the ink tube 36 are hermetically connected, and an engagement portion is formed on the fourth surface 2 d of the case 2 facing the engagement groove 37. 22 is provided, and the engaging portion 22 engages with the engaging groove 37. A chip 26 is further provided at a position facing the contact pin 31 of the case 2. Specifically, as shown in FIG. 7, the mounting surface 39 is a second inclined surface 392, and the chip 26 is provided on an inclined surface provided between the first surface 2a and the third surface 2c. The chip 26 is provided with storage means and terminals for storing information such as ink amount information, ink type, and manufacturer, and the terminals are electrically connected to the contact pins 31 in the mounting portion. Can be continuous. Specifically, a mounting space 395 is formed between the second inclined surface 392 and the mounting portion, and the contour shape of the mounting space 395 is formed by a facing surface that faces the second inclined surface 392 and the second inclined surface 392 in the mounting portion. Has been. More specifically, the opposing surfaces shown in FIGS. 7 and 9 are also inclined surfaces, and accordingly, the attachment space 395 exhibits a space that is inclined as a whole. The upper surface of the mounting space 395 is the mounting surface 39, that is, the far end 394 of the upper surface of the mounting space 395 is located in the + Z-axis direction of the near end 393. In some examples of change, the contour shape of the attachment space 395 also changes as the inclination angle of the attachment surface 39 changes or the shape of the facing surface changes.

１つの変化例では、取付ホルダー３２は、中実の形状を呈し、即ち、図３に示す第１斜面３９１と第２斜面３９２との間の空間がなくなり、これに応じて、取付ホルダー３２の−Ｚ軸方向の傾斜端面（第２斜面３９２の位置に相当）が取付面３９とされ、傾斜端面と装着部との間の空間が取付空間３９５とされる。   In one variation, the mounting holder 32 has a solid shape, that is, there is no space between the first slope 391 and the second slope 392 shown in FIG. The inclined end surface in the −Z-axis direction (corresponding to the position of the second inclined surface 392) is the mounting surface 39, and the space between the inclined end surface and the mounting portion is the mounting space 395.

更に、図７、９に示すように、ケース２の取付面３９に対向する側には、可動部材２３が設けられ、可動部材２３は、弾性支持部２３１と、回転部２３２と、接合部２３３とを含み、具体的には、弾性支持部２３１とケース２との間に弾性部材２４が設けられ、好ましくは、弾性部材２４はばねであり、接合部２３３が＋Ｘ軸方向へ延び取付空間３９５に進入して係合する。インクカートリッジの取り出しが必要である時、弾性支持部２３１に外力Ｆを与え、弾性支持部２３１が外力を受けたことに伴って、弾性部材２４が圧縮されることにより、可動部材２３が回転部２３２回りに回転する。可動部材２３の回転に伴って、接合部２３３が取付空間３９５から取り出される。好ましくは、図６に示すように、弾性支持部２３１が操作部２３４にも接続され、外力Ｆが操作部２３４に与えられてから、操作部２３４が外力Ｆを弾性支持部２３１に伝達することにより、同様の目的を達する。   Further, as shown in FIGS. 7 and 9, the movable member 23 is provided on the side facing the mounting surface 39 of the case 2, and the movable member 23 includes the elastic support portion 231, the rotating portion 232, and the joint portion 233. Specifically, the elastic member 24 is provided between the elastic support portion 231 and the case 2. Preferably, the elastic member 24 is a spring, and the joint portion 233 extends in the + X-axis direction and is attached to a mounting space 395. Enter and engage. When it is necessary to take out the ink cartridge, an external force F is applied to the elastic support portion 231, and the elastic member 24 is compressed as the elastic support portion 231 receives the external force. Rotate around 232 As the movable member 23 rotates, the joint portion 233 is taken out from the mounting space 395. Preferably, as shown in FIG. 6, after the elastic support portion 231 is also connected to the operation portion 234 and the external force F is applied to the operation portion 234, the operation portion 234 transmits the external force F to the elastic support portion 231. To achieve a similar purpose.

具体的には、図５、６、９に示すように、弾性支持部２３１は、力受け部２３１１を含み、本実施例における力受け部２３１１は、傾斜する面であり、以下、力受け面と称し、力受け面は、インクカートリッジが取り出される際に接合部２３３が動作する方向（図６に示す動作方向Ｓ）に垂直となり、力受け面のケースから離間する端が−Ｚ軸及び＋Ｘ軸の方向へ傾斜する。インクカートリッジの取り出しが必要である時、外力Ｆが力受け部２３１１に与えられ、回転部２３２が可動部材２３の回転軸心であり、Ｚ軸方向において弾性部材２４が弾性支持部２３１と接合部２３３との間に位置し、即ち、力受け部２３１１と接合部２３３との間に位置して、この場合、外力Ｆの方向が動作方向Ｓと一致することにより、接合部２３３と取付面３９とが相対的に抜き出すことに寄与する。そのうち、Ｘ軸方向において弾性支持部２３１と接合部２３３とが回転部２３２の＋Ｘ軸方向に位置し、力受け部２３１１は、傾斜方向が−Ｚ軸及び＋Ｘ軸方向へ傾斜する面であり、接合部２３３の動作方向Ｓは−Ｚ軸と−Ｘ軸方向に沿い、即ち、動作方向Ｓは、接合部２３３が回転部２３２を軸心として回転してなる円において接合部２３３での接線方向であることにより、接合部２３３と取付面３９との分離がさらに容易である。   Specifically, as shown in FIGS. 5, 6, and 9, the elastic support portion 231 includes a force receiving portion 2311, and the force receiving portion 2311 in the present embodiment is an inclined surface. The force receiving surface is perpendicular to the direction in which the joint portion 233 operates when the ink cartridge is taken out (operation direction S shown in FIG. 6), and the ends of the force receiving surface that are separated from the case are −Z axis and + X. Tilt in the direction of the axis. When the ink cartridge needs to be taken out, an external force F is applied to the force receiving portion 2311, the rotating portion 232 is the rotation axis of the movable member 23, and the elastic member 24 is joined to the elastic supporting portion 231 in the Z-axis direction. 223, that is, between the force receiving portion 2311 and the joint portion 233. In this case, the direction of the external force F coincides with the operation direction S, so that the joint portion 233 and the mounting surface 39 are located. Contributes to relative extraction. Among them, the elastic support portion 231 and the joint portion 233 are positioned in the + X-axis direction of the rotating portion 232 in the X-axis direction, and the force receiving portion 2311 is a surface whose inclination direction is inclined in the −Z axis and the + X-axis direction, The operation direction S of the joint portion 233 is along the −Z axis and −X axis directions, that is, the operation direction S is a tangential direction at the joint portion 233 in a circle formed by the joint portion 233 rotating around the rotation portion 232. Therefore, the separation between the joint portion 233 and the attachment surface 39 is further facilitated.

加工誤差及び組立誤差があるので、接合部２３３と取付面３９との接合時の接合位置の誤差が大きいと、チップ２６が元の位置からずれ、チップ２６と接触ピン３１とが接触不良になるおそれがあるため、接合部２３３の方が回転部２３２よりもチップ２６に近くなることにより、チップ２６の位置誤差をできるだけ小さくする。   Since there are processing errors and assembly errors, if the error in the joining position when joining the joint portion 233 and the mounting surface 39 is large, the tip 26 is displaced from the original position, and the tip 26 and the contact pin 31 are in poor contact. Since there is a possibility that the joining portion 233 is closer to the chip 26 than the rotating portion 232, the position error of the chip 26 is made as small as possible.

更に、Ｘ軸方向においてチップ２６がインク供給口２１と接合部２３３との間に位置し、即ち、インク供給口２１よりもチップ２６の方が接合部２３３に近い。インク供給口２１とチップ２６との間にある程度の距離を設けることにより、インク供給口２１からインクが漏れる場合にチップ２６に影響を与えることを防止し、チップ２６と接触ピン３１との接触不良が避けられる。同様に、Ｚ軸方向において、チップ２６がインク供給口２１と接合部２３３との間に位置し、即ち、インク供給口２１とチップ２６とが面一ではない。   Further, the chip 26 is positioned between the ink supply port 21 and the joint portion 233 in the X-axis direction, that is, the chip 26 is closer to the joint portion 233 than the ink supply port 21. By providing a certain distance between the ink supply port 21 and the chip 26, it is possible to prevent the chip 26 from being affected when ink leaks from the ink supply port 21, and poor contact between the chip 26 and the contact pin 31. Can be avoided. Similarly, in the Z-axis direction, the chip 26 is positioned between the ink supply port 21 and the joint portion 233, that is, the ink supply port 21 and the chip 26 are not flush with each other.

上記実施例では、Ｘ軸の方向において、図８〜９の実施例におけるインク供給口２１と接合部２３３との距離が、図５〜７の実施例におけるインク供給口２１と接合部２３３との距離よりも小さく、Ｚ軸方向において、図８〜９の実施例における力受け部２３１１と回転部２３２との距離Ｄ１が、図５〜７の実施例中における力受け部２３１１と回転部２３２との距離Ｄ１よりも大きく、図８〜９の実施例における接合部２３３と回転部２３２との距離Ｄ２が、図５〜７の実施例における接合部２３３と回転部２３２との距離Ｄ２よりも大きい。オプションとして、図５〜７において、Ｄ１＝９．２６ｍｍ、Ｄ２＝１９．４１ｍｍとされ、図８〜９において、Ｄ１＝１１．４１ｍｍ、Ｄ２＝２２．２３ｍｍとされる。図８〜９実施例におけるアームが比較的に長いので、小さい外力Ｆでもインクカートリッジを取り出すことが可能あり、インクカートリッジの取り出しが容易になる。   In the above embodiment, in the X axis direction, the distance between the ink supply port 21 and the joint portion 233 in the embodiment of FIGS. 8 to 9 is the distance between the ink supply port 21 and the joint portion 233 in the embodiment of FIGS. The distance D1 between the force receiving portion 2311 and the rotating portion 232 in the embodiment of FIGS. 8 to 9 in the Z-axis direction is smaller than the distance, and the force receiving portion 2311 and the rotating portion 232 in the embodiment of FIGS. The distance D2 between the joint portion 233 and the rotating portion 232 in the embodiment of FIGS. 8 to 9 is larger than the distance D2 between the joint portion 233 and the rotating portion 232 in the embodiment of FIGS. . As an option, in FIGS. 5 to 7, D1 = 9.26 mm and D2 = 19.41 mm, and in FIGS. 8 to 9, D1 = 11.41 mm and D2 = 22.23 mm. 8-9, since the arm is relatively long, the ink cartridge can be taken out even with a small external force F, and the ink cartridge can be easily taken out.

１つの変化例では、回転部２３２が省略されてもよい。これに応じて、インクカートリッジの取り出しが必要である時、依然として弾性支持部２３１に外力Ｆを与え、弾性支持部２３１が外力を受けて弾性部材２４の圧縮を駆動することにより、可動部材２３全体が−Ｚ軸方向へ移動して、インクカートリッジに−Ｘ軸方向の作用力を与えて、インクカートリッジ全体が−Ｘ軸方向へ移動する。この場合、接触ピン３１がインクカートリッジに＋Ｚ軸方向への弾性力を与えることにより、インクカートリッジが上方に跳ね上げ、接合部２３３が取付空間３９５から抜け出す。このようにしても、インクカートリッジの取り出しが完了することができる。   In one variation, the rotating unit 232 may be omitted. Accordingly, when the ink cartridge needs to be taken out, the external force F is still applied to the elastic support portion 231, and the elastic support portion 231 receives the external force to drive the compression of the elastic member 24. Moves in the −Z-axis direction and applies an acting force in the −X-axis direction to the ink cartridge, so that the entire ink cartridge moves in the −X-axis direction. In this case, the contact pin 31 applies an elastic force in the + Z-axis direction to the ink cartridge, so that the ink cartridge jumps upward and the joint portion 233 comes out of the mounting space 395. Even in this way, the removal of the ink cartridge can be completed.

第１実施例として、取付ホルダー３２が省略し、これに応じて、取付面は、装着部に設けられる斜面である。具体的には、図３を参照して説明すると、第１斜面３９１のみを残り、これに応じて、第２斜面３９２は、装着部の一部であり、即ち、第２斜面３９２は、装着部における取付面に対向する対向面であり、第１斜面３９１と対向面との間の空間が取付空間３９５とされる。   As a first embodiment, the mounting holder 32 is omitted, and the mounting surface is a slope provided on the mounting portion accordingly. Specifically, referring to FIG. 3, only the first slope 391 remains, and accordingly, the second slope 392 is a part of the mounting portion, that is, the second slope 392 is mounted. The space between the first inclined surface 391 and the facing surface is a mounting surface 395 that is a facing surface that faces the mounting surface in the section.

第２実施例として、図４に示すように、取付ホルダー３２が省略し、取付面３９は、Ｙ軸方向に延在するとともに、装着部におけるＹ軸方向に対して垂直となる２つの側面を連結し、即ち、取付面３９は、Ｙ軸方向に装着部全体に亘る斜面であり、これに応じて、取付面３９の−Ｚ軸方向の端面（図示しない）と装着部との間の空間が取付空間３９５とされる。１種の変化として、図４に示す装着部全体に亘る取付面３９が複数段の斜面（図示しない）に分割されてもよく、これに応じて、複数段の斜面と装着部とにより複数個の取付空間３９５が形成される。   As a second embodiment, as shown in FIG. 4, the mounting holder 32 is omitted, and the mounting surface 39 extends in the Y-axis direction and has two side surfaces perpendicular to the Y-axis direction in the mounting portion. In other words, the attachment surface 39 is a slope extending over the entire mounting portion in the Y-axis direction, and accordingly, a space between the end surface (not shown) in the −Z-axis direction of the mounting surface 39 and the mounting portion. Is a mounting space 395. As one type of change, the mounting surface 39 over the entire mounting portion shown in FIG. 4 may be divided into a plurality of slopes (not shown), and a plurality of slopes and mounting portions are provided accordingly. A mounting space 395 is formed.

更に、上述した実施例にかかる取付面３９のいずれも装着部とともに取付空間３９５を形成することができ、当業者は、図７、９に示す構成の模式図を参照して上述した実施例における接合部２３３と取付空間３９５との係合態様を理解することができる。具体的には、上述した実施例では、インクカートリッジの装着部からの取り出しの態様は、図７、９に示す実施例と類似するので、ここで重複しない。   Furthermore, any of the mounting surfaces 39 according to the above-described embodiments can form the mounting space 395 together with the mounting portion, and those skilled in the art can refer to the schematic diagrams of the configurations shown in FIGS. The manner of engagement between the joint 233 and the mounting space 395 can be understood. Specifically, in the above-described embodiment, the mode of taking out the ink cartridge from the mounting portion is similar to the embodiment shown in FIGS.

第３実施例として、図１１、図１６に示すように、可動部材２３は、被付勢部２３５と、弾性支持部２３１と、接合部２３３と、摺動部２３６とを備え、被付勢部２３５が回転レバー３４に対向して設けられ、被付勢部２３５が回転レバー３４による押動で動くすることができ、弾性支持部２３１とケース２との間に弾性部材２４が設けられている。具体的には、図３に示すものと類似し、図１１から見えるように、取付ホルダー（図１１において番号が付けられない）は、第１斜面３９１と、第２斜面３９２とを備え、ただし、本実施例では、第１斜面３９１そのものは取付面３９であり、第１斜面３９１と第２斜面３９２との間に取付空間３９５が形成され、第１斜面３９１の−Ｘ軸側が近端３９３であり、＋Ｘ軸側が遠端３９４であり、インクカートリッジが装着部に取り付けられた後、近端３９３がインクカートリッジに近く、遠端３９４がインクカートリッジから遠いとともに、＋Ｚ軸方向において遠端３９４が近端３９３よりも高く、即ち、遠端３９４が近端３９３の＋Ｚ軸方向に位置する。より具体的には、取付空間３９５の上面は、第１斜面３９１であり、即ち、取付空間３９５の上面の遠端３９４が近端３９３の＋Ｚ軸方向に位置する。   As a third embodiment, as shown in FIGS. 11 and 16, the movable member 23 includes a biased portion 235, an elastic support portion 231, a joint portion 233, and a sliding portion 236. The portion 235 is provided to face the rotation lever 34, the biased portion 235 can move by being pushed by the rotation lever 34, and the elastic member 24 is provided between the elastic support portion 231 and the case 2. Yes. Specifically, similar to that shown in FIG. 3, as can be seen from FIG. 11, the mounting holder (not numbered in FIG. 11) comprises a first slope 391 and a second slope 392, provided that In the present embodiment, the first slope 391 itself is the attachment surface 39, an attachment space 395 is formed between the first slope 391 and the second slope 392, and the −X axis side of the first slope 391 is the near end 393. The + X axis side is the far end 394, and after the ink cartridge is attached to the mounting portion, the near end 393 is close to the ink cartridge, the far end 394 is far from the ink cartridge, and the far end 394 in the + Z axis direction is It is higher than the near end 393, that is, the far end 394 is located in the + Z-axis direction of the near end 393. More specifically, the upper surface of the attachment space 395 is the first inclined surface 391, that is, the far end 394 of the upper surface of the attachment space 395 is located in the + Z-axis direction of the near end 393.

具体的には、回転レバー３４は、押付部３４２と手押部３４３とを含み、押付部３４２が被付勢部２３５に対向して設けられ、押付部３４２は、インクカートリッジが取り出される際、可動部材２３における被付勢部２３５に外力を与える部分であり、手押部３４３は、装着部からインクカートリッジを取り出す際に、使用者に操作される部分である。外力が回転レバー３４に与えられるにより、より良好に被付勢部２３５に伝達されることができ、インクカートリッジの取り出しが容易になる。   Specifically, the rotation lever 34 includes a pressing portion 342 and a hand pressing portion 343, and the pressing portion 342 is provided to face the urged portion 235. When the ink cartridge is taken out, the pressing portion 342 is provided. The movable member 23 is a portion that applies an external force to the biased portion 235, and the hand pressing portion 343 is a portion that is operated by the user when the ink cartridge is taken out from the mounting portion. When the external force is applied to the rotation lever 34, it can be transmitted to the biased portion 235 better, and the ink cartridge can be easily taken out.

図１２、１５に示すように、インクカートリッジの取り出し中、使用者が回転レバー３４の手押部３４３に外力Ｇを与え、回転レバー３４の回転作用により、押付部３４２が被付勢部２３５に接触して被付勢部２３５に作用力Ｈを与え、被付勢部２３５が可動部材２３の上半部に位置すると、Ａ点（可動部材２３の下方とケース２との接触部位）を回転中心とするモーメントが発生する。発生したモーメントは、Ａ点を回転中心とする反時計回りのモーメントＭ１であり、そのモーメントによって可動部材２３が抜け出す恐れがあり、または、Ａ点がひどく磨耗することにより接合部２３３の位置が変化してしまう。この場合、接合部２３３が第１斜面３９１に接合され、接合部２３３が第１斜面３９１からの作用力Ｊを受け、作用力ＪによってＡ点を回転中心とする時計回りのモーメントＭ２が発生し、Ｍ２とＭ１とが相殺する作用を有する。   As shown in FIGS. 12 and 15, during the removal of the ink cartridge, the user applies an external force G to the hand pressing portion 343 of the rotating lever 34, and the pressing portion 342 is applied to the biased portion 235 by the rotating action of the rotating lever 34. When contacted, an acting force H is applied to the urged portion 235 and the urged portion 235 is positioned in the upper half of the movable member 23, the point A (the contact portion between the lower portion of the movable member 23 and the case 2) is rotated. A center moment is generated. The generated moment is a counterclockwise moment M1 with the point A as the center of rotation, and the movable member 23 may come off due to the moment, or the position of the joint 233 changes due to the point A being worn excessively. Resulting in. In this case, the joint portion 233 is joined to the first slope 391, the joint portion 233 receives the acting force J from the first slope 391, and a clockwise moment M2 around the point A is generated by the acting force J. , M2 and M1 cancel each other.

上記の分析に基づいて、外力Ｇ及び被付勢部２３５が受けた作用力Ｈを小さくするために、被付勢部２３５が回転レバー３４による押動で回転支点（Ａ点）回りに回転可能であり、接合部２３３が被付勢部２３５よりも回転支点（Ａ点）に近く、即ち、被付勢部２３５が接合部２３３よりも回転支点から遠い。図１２、１５において、被付勢部２３５からＡ点までの距離Ｄ２が接合部２３３からＡ点までの距離Ｄ１よりも長い。インクカートリッジの取り出し中、接合部２３３と第１斜面３９１との間の摩擦力及び可動部材２３とケース２との間の摩擦力に抗する必要があるので、接合部２３３と第１斜面３９１との間の摩擦力、可動部材２３とケース２との間の摩擦力が一定である場合に、Ｄ２＞Ｄ１とすると、作用力Ｈの低減に寄与し、インクカートリッジの取り出しが更に容易である。そのうち、Ｚ軸方向において、Ｈの外力と接合部２３３との距離がＤ３とされ、作用力Ｈと回転支点との距離がＤ４とされ、Ｘ軸の方向において、接合部２３３と回転支点との距離がＤ５とされる。図１１〜１３において、Ｄ１＝６．８２ｍｍ、Ｄ２＝１３．４８ｍｍ、Ｄ３＝５．１ｍｍ、Ｄ４＝６．２２ｍｍ、Ｄ１のＤ２に対する比が０．６よりも小さいことが好ましい。図１４〜１５において、Ｄ１＝１３．６３ｍｍ、Ｄ２＝１４．２３ｍｍ、Ｄ３＝６．２７ｍｍ、Ｄ４＝１７．８９ｍｍ、Ｄ５＝７．１２ｍｍ、Ｄ１のＤ２に対する比が１よりも小さいことが好ましい。   Based on the above analysis, in order to reduce the external force G and the acting force H received by the urged portion 235, the urged portion 235 can be rotated around the rotation fulcrum (point A) by being pushed by the rotating lever 34. The joint portion 233 is closer to the rotation fulcrum (point A) than the biased portion 235, that is, the biased portion 235 is farther from the rotation fulcrum than the joint portion 233. 12 and 15, the distance D2 from the biased portion 235 to the point A is longer than the distance D1 from the joint portion 233 to the point A. Since it is necessary to resist the frictional force between the joint 233 and the first slope 391 and the frictional force between the movable member 23 and the case 2 while the ink cartridge is being taken out, the joint 233 and the first slope 391 When the frictional force between the two and the frictional force between the movable member 23 and the case 2 is constant, if D2> D1, it contributes to the reduction of the acting force H, and the ink cartridge can be taken out more easily. Among them, the distance between the external force of H and the joint 233 in the Z-axis direction is D3, the distance between the acting force H and the rotation fulcrum is D4, and the distance between the joint 233 and the rotation fulcrum in the X-axis direction. The distance is D5. 11 to 13, D1 = 6.82 mm, D2 = 13.48 mm, D3 = 5.1 mm, D4 = 6.22 mm, and the ratio of D1 to D2 is preferably smaller than 0.6. 14 to 15, D1 = 13.63 mm, D2 = 14.23 mm, D3 = 6.27 mm, D4 = 17.89 mm, D5 = 7.12 mm, and the ratio of D1 to D2 is preferably smaller than 1.

図１１〜１３において、接合部２３３が第１斜面３９１に接合される一方、図１４〜１５において、接合部２３３が第２斜面３９２に接合されるので、図１４〜１５において、接合部２３３がチップ２６により近い。   11 to 13, the joint portion 233 is joined to the first slope 391, while in FIGS. 14 to 15, the joint portion 233 is joined to the second slope 392. It is closer to the chip 26.

第３実施例のいくつかの変化として、取付面３９が装着部に直接設けられ、即ち、図１１における第１斜面３９１が取付面３９とされるとともに、第２斜面３９２が装着部の一部（即ち、装着部における取付面に対応する対向面）であり、これに応じて、取付面３９と対向面との間に取付空間３９５が形成され、接合部２３３が取付空間３９５内に係合する。より具体的には、図１１は、可動部材２３がケース２内に取り付けられた状態を示し、図１６を参照して、可動部材２３がケース２内に取り付けられ、摺動部２３６がケース２（図１１では視線の原因で見えられない）に密着し、これに対して、図７、図１１と比較して見えるに、図７における弾性部材２４と図１１における弾性部材２４の設置態様が異なり、図７における弾性部材２４の軸線方向がＺ軸方向に設けられる一方、図１１における弾性部材２４の軸線方向がＸ軸方向に設けられる。図１１に示す実施例における弾性部材２４の設置態様を参照して、インクカートリッジの取り出しが必要である時、外力Ｇが回転レバー３４に与えられ、回転レバー３４が受けた外力を弾性支持部２３１に伝達して、弾性支持部２３１によって弾性部材２４が圧縮されることにより、摺動部２３６がケース２に対して摺動し、弾性部材２４全体が−Ｘ軸方向へ動いてから、接合部２３３が取付空間３９５から抜き出し、インクカートリッジが接触ピン３１の弾性力で跳ね上げ、その後、インクカートリッジが装着部から取り出される。   As some changes of the third embodiment, the mounting surface 39 is provided directly on the mounting portion, that is, the first slope 391 in FIG. 11 is used as the mounting surface 39 and the second slope 392 is a part of the mounting portion. (That is, a facing surface corresponding to the mounting surface in the mounting portion). Accordingly, a mounting space 395 is formed between the mounting surface 39 and the facing surface, and the joint portion 233 is engaged in the mounting space 395. To do. More specifically, FIG. 11 shows a state in which the movable member 23 is attached in the case 2, and referring to FIG. 16, the movable member 23 is attached in the case 2, and the sliding portion 236 is in the case 2. (It is not visible in FIG. 11 because of the line of sight), and compared with FIGS. 7 and 11, the installation mode of the elastic member 24 in FIG. 7 and the elastic member 24 in FIG. Unlike the axial direction of the elastic member 24 in FIG. 7 is provided in the Z-axis direction, the axial direction of the elastic member 24 in FIG. 11 is provided in the X-axis direction. Referring to the installation mode of the elastic member 24 in the embodiment shown in FIG. 11, when the ink cartridge needs to be taken out, the external force G is applied to the rotation lever 34, and the external force received by the rotation lever 34 is used as the elastic support portion 231. , The elastic member 24 is compressed by the elastic support portion 231, so that the sliding portion 236 slides with respect to the case 2, and the entire elastic member 24 moves in the −X axis direction. 233 is extracted from the mounting space 395, the ink cartridge is flipped up by the elastic force of the contact pin 31, and then the ink cartridge is removed from the mounting portion.

１種の変化として、図１７は、他の種類の可動部材２３の構成の模式図を示す。図１６と図１７とを比較して見えるように、２種類の可動部材２３は、接合部２３３が異なる点で相違し、図１６における接合部２３３は、可動部材２３の＋Ｘ軸方向の端部に設けられる塊状の凸部のみである一方、図１７における接合部２３３は、＋Ｘ軸方向に延在する棒状物であり、且つ棒状物の＋Ｘ軸方向の端部に塊状の凸部が形成される。当業者は、以下のことを理解することができる。即ち、図１７に示す可動部材２３と取付空間３９５との係合方式が、図１６における可動部材２３と取付空間３９５との係合方式に類似し、ただし、図１７に示す可動部材２３の強度が図１６における可動部材２３よりも高く、これに応じて、図１７における可動部材２３が取り付けられたインクカートリッジの取付及び取り出しの方式が第３実施例に類似するので、ここで重複しない。   As one type of change, FIG. 17 shows a schematic diagram of the configuration of another type of movable member 23. As can be seen by comparing FIG. 16 and FIG. 17, the two types of movable member 23 are different in that the joint portion 233 is different, and the joint portion 233 in FIG. 16 is the end portion of the movable member 23 in the + X-axis direction. 17 is a bar-like object extending in the + X-axis direction, and a bar-like protrusion is formed at the end of the bar-like object in the + X-axis direction. The A person skilled in the art can understand the following. That is, the engagement method between the movable member 23 and the attachment space 395 shown in FIG. 17 is similar to the engagement method between the movable member 23 and the attachment space 395 in FIG. 16, except that the strength of the movable member 23 shown in FIG. 16 is higher than the movable member 23 in FIG. 16, and accordingly, the method of attaching and taking out the ink cartridge to which the movable member 23 in FIG. 17 is attached is similar to that of the third embodiment, so that it does not overlap here.

第４実施例として、図１８に示すように、可動部材２３は、操作部２３４と、回転部２３２と、接合部２３３とを含み、可動部材２３が回転部２３２を介してケース２に接続され、操作部２３４は、外力を受けて可動部材２３が回転部２３２回りに回転するように駆動する。具体的には、図１８に示す可動部材２３には、Ｙ軸方向に２つの接合部２３３が設けられている。当業者は、１つの接合部２３３でも、または複数の接合部２３３でも、本発明の目的を達成できることが、理解できる。より具体的には、図１８における可動部材２３が取り付けられたインクカートリッジが同様に装着部に取り付けられ、且つ、可動部材２３が前記いずれの実施例における取付面３９にかみ合うことが可能であり、これに応じて、インクカートリッジの取り出しが必要である時、操作部２３４に−Ｘ軸方向への作用力を与え、可動部材２３が−Ｘ軸方向に回転してから、可動部材２３と取付面３９とが離れ、インクカートリッジが接触ピン３１の弾性力で跳ね上げ、その後、インクカートリッジが装着部から取り出される。   As a fourth embodiment, as shown in FIG. 18, the movable member 23 includes an operation unit 234, a rotation unit 232, and a joint unit 233, and the movable member 23 is connected to the case 2 via the rotation unit 232. The operation unit 234 receives an external force and drives the movable member 23 to rotate around the rotation unit 232. Specifically, the movable member 23 shown in FIG. 18 is provided with two joint portions 233 in the Y-axis direction. One skilled in the art can appreciate that the object of the present invention can be achieved with a single joint 233 or multiple joints 233. More specifically, the ink cartridge to which the movable member 23 in FIG. 18 is attached is similarly attached to the mounting portion, and the movable member 23 can be engaged with the attachment surface 39 in any of the above embodiments. Accordingly, when it is necessary to take out the ink cartridge, an operating force in the −X-axis direction is applied to the operation unit 234 and the movable member 23 rotates in the −X-axis direction. 39, the ink cartridge is flipped up by the elastic force of the contact pin 31, and then the ink cartridge is taken out from the mounting portion.

図１９〜２１に示すように、Ｘ軸方向において接合部２３３が操作部２３４と回転部２３２との間に位置し、Ｚ軸方向において接合部２３３が操作部２３４と回転部２３２との間に位置することにより、可動部材２３の可動空間を小さくさせる。   As shown in FIGS. 19 to 21, the joint portion 233 is located between the operation portion 234 and the rotation portion 232 in the X-axis direction, and the joint portion 233 is located between the operation portion 234 and the rotation portion 232 in the Z-axis direction. By positioning, the movable space of the movable member 23 is made small.

この実施例では、Ｘ軸方向においてチップ２６がインク供給口２１と接合部２３３との間に位置し、即ち、インク供給口２１よりも、チップ２６の方が接合部２３３に近い。Ｚ軸方向においてチップ２６がインク供給口２１と接合部２３３との間に位置する。   In this embodiment, the chip 26 is located between the ink supply port 21 and the bonding portion 233 in the X-axis direction, that is, the chip 26 is closer to the bonding portion 233 than the ink supply port 21. The chip 26 is located between the ink supply port 21 and the joint portion 233 in the Z-axis direction.

そのうち、Ｘ軸の方向において、図２１の実施例におけるインク供給口２１と接合部２３３との距離が、図１９の実施例におけるインク供給口２１と接合部２３３との距離よりも小さく、Ｚ軸方向において、操作部２３４と接合部２３３との距離がＤ１とされ、操作部２３４と回転部２３２との距離がＤ２とされ、操作部２３４とチップ２６との距離がＤ３とされる。図１９において、Ｄ１＝９．１９ｍｍ、Ｄ２＝１６．７６ｍｍ、Ｄ３＝２３．０７ｍｍとされ、図２１において、Ｄ１＝２０．７５ｍｍ、Ｄ２＝２３．１６ｍｍ、Ｄ３＝２８．４６ｍｍとされることが好ましい。   Among these, in the X-axis direction, the distance between the ink supply port 21 and the joint portion 233 in the embodiment of FIG. 21 is smaller than the distance between the ink supply port 21 and the joint portion 233 in the embodiment of FIG. In the direction, the distance between the operation part 234 and the joint part 233 is D1, the distance between the operation part 234 and the rotation part 232 is D2, and the distance between the operation part 234 and the chip 26 is D3. In FIG. 19, D1 = 9.19 mm, D2 = 16.76 mm, and D3 = 23.07 mm. In FIG. 21, D1 = 20.75 mm, D2 = 23.16 mm, and D3 = 28.46 mm. preferable.

明らかに、上述した各実施例では、取付面３９が回転レバー３４に設けられないことにより、回転レバー３４の作動による接合部２３３への影響が低減される。   Obviously, in each of the above-described embodiments, since the attachment surface 39 is not provided on the rotating lever 34, the influence on the joint portion 233 due to the operation of the rotating lever 34 is reduced.

図２２及び図２３は、従来技術の１種のインクカートリッジ（詳細は中国出願ＣＮ２００７１０１４６６２４．４の記載を参照）を示す。従来技術のインクカートリッジは、負圧室１０２とインク室１０３とを備え、負圧室１０２では、負圧スポンジを負圧機構として、インクカートリッジ内部の負圧が制御される。しかし、使用者のインクカートリッジのインク量に対する要求が高くなることに伴って、負圧スポンジの新材質に対する研究開発により、負圧室１０２の体積を低減するとともにインク室１０３の体積を増加することができる。インクカートリッジ内部の負圧を更に安定させるように、インクカートリッジの吸気口１０４から気体を導入することにより、インクカートリッジ内部の気体を均一にさせるようにする。具体的には、図２２に示すように、従来技術のインクカートリッジは、＋Ｘ軸方向に空気室１０１と、負圧室１０２と、インク室１０３とに順次に分割され、図面から見えるように、インクカートリッジの内部空間の大半が空気室１０１及び負圧室１０２とされるので、インク室１０３の空間が低減される。実際の使用中、インク供給口がインクカートリッジのＸ軸の側辺に位置せず、且つ、インクカートリッジの技術の発展に伴って、製造メーカーがインク供給口をインクカートリッジの底部の中央に近い位置に設置して行くので、負圧室とインク供給口との連通を確保するため、インクカートリッジにおけるインク供給口の−Ｘ軸側にある領域がインク貯留のために利用されない。この技術課題から見れば、インクカートリッジのインク量にまだ広がる空間がある。   22 and 23 show one kind of ink cartridge of the prior art (for details, see the description of Chinese application CN200710114624.4). The ink cartridge of the prior art includes a negative pressure chamber 102 and an ink chamber 103. In the negative pressure chamber 102, the negative pressure inside the ink cartridge is controlled using a negative pressure sponge as a negative pressure mechanism. However, as the user's demand for the ink amount of the ink cartridge becomes higher, the volume of the negative pressure chamber 102 and the volume of the ink chamber 103 are increased by research and development on a new material of the negative pressure sponge. Can do. In order to further stabilize the negative pressure inside the ink cartridge, the gas inside the ink cartridge is made uniform by introducing the gas from the air inlet 104 of the ink cartridge. Specifically, as shown in FIG. 22, the prior art ink cartridge is sequentially divided into an air chamber 101, a negative pressure chamber 102, and an ink chamber 103 in the + X-axis direction, as can be seen from the drawing. Since most of the internal space of the ink cartridge is the air chamber 101 and the negative pressure chamber 102, the space of the ink chamber 103 is reduced. During actual use, the ink supply port is not located on the side of the X axis of the ink cartridge, and with the development of the ink cartridge technology, the manufacturer places the ink supply port closer to the center of the bottom of the ink cartridge. In order to ensure communication between the negative pressure chamber and the ink supply port, the region on the −X-axis side of the ink supply port in the ink cartridge is not used for ink storage. In view of this technical problem, there is still a space that extends to the ink amount of the ink cartridge.

更に、図２４は、第５実施例を示す。本実施例のＸ軸、Ｙ軸、Ｚ軸が第１実施例のＸ軸、Ｙ軸、Ｚ軸と一致する。インクカートリッジのケース２内には、空気室２５１と、負圧室２５２と、第１インク室２５３と、第２インク室２５４とが設けられている。第１インク室２５３と第２インク室２５４とが、上述した各実施例におけるインクカートリッジのインク室を構成している。空気室２５１と、負圧室２５２と、第２インク室２５４とが、この順で＋Ｘ軸方向に設けられる。第１インク室２５３がＹ軸方向に空気室２５１と負圧室２５２とに隣接して設けられる。具体的には、負圧室２５２内に負圧スポンジが充填され、インク供給口２１内にインク供給口スポンジが充填されている。好ましくは、インク供給口スポンジと負圧スポンジとの密度が一致し、これにより、両方の密度の相違によりプリンタが無駄にプリントすること、または待機際にインクが落下することを防止することができる。図２２と図２４とを比較して見えるように、図２２に示す従来技術と比べ、図２４におけるケース２のＹ軸方向の一部に空気室２５１と、負圧室２５２と、第１インク室２５３とが設けられることにより、空気室２５１の体積が低減されるとともに、インク室の体積が増加され、インクカートリッジのインク貯留量が増加される。そして、Ｘ軸方向に、インク室がインクカートリッジのケース２全体に亘る。   FIG. 24 shows a fifth embodiment. The X-axis, Y-axis, and Z-axis of the present embodiment coincide with the X-axis, Y-axis, and Z-axis of the first embodiment. In the case 2 of the ink cartridge, an air chamber 251, a negative pressure chamber 252, a first ink chamber 253, and a second ink chamber 254 are provided. The first ink chamber 253 and the second ink chamber 254 constitute the ink chamber of the ink cartridge in each of the embodiments described above. An air chamber 251, a negative pressure chamber 252, and a second ink chamber 254 are provided in this order in the + X-axis direction. A first ink chamber 253 is provided adjacent to the air chamber 251 and the negative pressure chamber 252 in the Y-axis direction. Specifically, the negative pressure chamber 252 is filled with a negative pressure sponge, and the ink supply port 21 is filled with an ink supply port sponge. Preferably, the densities of the ink supply port sponge and the negative pressure sponge match, thereby preventing the printer from printing wastefully due to the difference in density between the two, or the ink falling off during standby. . As can be seen by comparing FIG. 22 and FIG. 24, compared with the prior art shown in FIG. 22, the air chamber 251, the negative pressure chamber 252, and the first ink are partially in the Y-axis direction of the case 2 in FIG. 24. By providing the chamber 253, the volume of the air chamber 251 is reduced, the volume of the ink chamber is increased, and the ink storage amount of the ink cartridge is increased. Then, the ink chamber extends over the entire case 2 of the ink cartridge in the X-axis direction.

更に、Ｙ軸方向にいて、第１インク室２５３が広すぎると、負圧室２５２が狭すぎになる。すると、インクカートリッジの内部の負圧が足りなくなってします。１つの好適な案として、インクカートリッジのＹ軸方向の幅をＤ、第１インク室２５３の少なくとも一部のＹ軸方向の幅をＤ１、負圧室２５２のＹ軸方向の幅をＤ２とする場合に、Ｄ１≦Ｄ／３、Ｄ２≧２Ｄ／３である。具体的には、第１インク室２５３の＋Ｘ軸方向の幅が均等ではないと、Ｄ１が第１インク室２５３のＹ軸方向の幅の最も狭い部分であり、第１インク室２５３の＋Ｘ軸方向の幅が均等であると、第１インク室２５３のＹ軸方向の幅がＤ１そのものであることが好ましい。 Furthermore, if the first ink chamber 253 is too wide in the Y-axis direction, the negative pressure chamber 252 becomes too narrow. Then, the negative pressure inside the ink cartridge will be insufficient. As one preferable proposal, the width in the Y-axis direction of the ink cartridge is D, the width in the Y-axis direction of at least a part of the first ink chamber 253 is D 1 , and the width in the Y-axis direction of the negative pressure chamber 252 is D2. In this case, D 1 ≦ D / 3 and D 2 ≧ 2D / 3. Specifically, when the width of the + X-axis direction of the first ink chamber 253 is not uniform, D 1 is the narrowest part of the Y-axis direction of the width of the first ink chamber 253, the first ink chamber 253 + X If the axial width is uniform, the width of the first ink chamber 253 in the Y-axis direction is preferably D 1 itself.

更に、第１インク室２５３は、＋Ｘ軸方向に順次に分布される第１部分２５３１と第２部分２５３２とを備え、図２４に示すように、Ｙ軸方向において第１部分２５３１の幅が第２部分２５３２の幅よりも大きく、第１部分２５３１がＹ軸方向に負圧室２５２に隣接して設けられ、第２部分２５３２がＹ軸方向に空気室２５１に隣接して設けられる。具体的には、第２部分２５３２は、一本の通路であり、図２６に示すように、第２部分２５３２と第２インク室２５４との間に連通口２５６が設けられることにより、第２部分２５３２が第１部分２５３１と第２インク室２５４とを連通することができ、そのような設計により、第１インク室２５３の空間を充分に利用するという目的が達成することができる。より具体的には、図２５に示すように、第５実施例におけるインクカートリッジにも吸気口２５５が設けられ、その作用が図２２に示す従来技術のインクカートリッジに類似するので、ここで重複しない。   Furthermore, the first ink chamber 253 includes a first portion 2531 and a second portion 2532 that are sequentially distributed in the + X-axis direction. As shown in FIG. 24, the width of the first portion 2531 is the first in the Y-axis direction. The first portion 2531 is provided adjacent to the negative pressure chamber 252 in the Y-axis direction, and the second portion 2532 is provided adjacent to the air chamber 251 in the Y-axis direction. Specifically, the second portion 2532 is a single passage, and as shown in FIG. 26, the communication port 256 is provided between the second portion 2532 and the second ink chamber 254, so that the second portion 2532 The portion 2532 can communicate the first portion 2531 and the second ink chamber 254. With such a design, the purpose of fully utilizing the space of the first ink chamber 253 can be achieved. More specifically, as shown in FIG. 25, the ink cartridge in the fifth embodiment is also provided with an air inlet 255, and its operation is similar to that of the prior art ink cartridge shown in FIG. .

更に、図２７及び図２８を参照すると、第１インク室２５３が第１連通路２５７を介してインク供給口２１に連通され、第２インク室２５４が第２連通路２５８を介してインク供給口２１に連通され、負圧室２５２が第３連通路２５９を介してインク供給口２１に連通される。具体的には、図２４を参照して見えるように、前記Ｄ１は第２部分２５３２の幅であり、これに応じて、第１連通路２５７の形状は長細いスリットである。第１連通路２５７により、第１インク室２５３がインク供給口２１に直接連通することができ、これにより、インクをインク供給口スポンジに供給することができる。すると、プリンタが連続してプリントする場合に、負圧スポンジの吸収能力不足によるインク供給不良を防止することができる。そして、第１連通路２５７が長細いものであるので、インクカートリッジが待機する場合にインクが落下することを防止することができる。 27 and 28, the first ink chamber 253 communicates with the ink supply port 21 via the first communication path 257, and the second ink chamber 254 communicates with the ink supply port via the second communication path 258. 21, and the negative pressure chamber 252 communicates with the ink supply port 21 via the third communication path 259. Specifically, as can be seen with reference to FIG. 24, the D 1 is the width of the second portion 2532, and the shape of the first communication path 257 is a long and narrow slit accordingly. The first communication passage 257 allows the first ink chamber 253 to communicate directly with the ink supply port 21, thereby supplying ink to the ink supply port sponge. Then, when the printer continuously prints, it is possible to prevent ink supply failure due to insufficient absorption capacity of the negative pressure sponge. And since the 1st communicating path 257 is long and thin, when an ink cartridge stands by, it can prevent that an ink falls.
