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 the second slope 392, and the chip 26 is provided on the slope provided between the first surface 2a and the third surface 2c. In addition, the chip 26 is fixed to the chip holder, and the chip 26 is provided with a storage means and a terminal for storing information such as ink amount information, ink type, and manufacturer, and the terminal is electrically connected to the contact pin 31 in the mounting portion. It is possible to be continuous. Specifically, a mounting space 395 is formed between the second slope 392 and the mounting portion, and the contour shape of the mounting space 395 is formed by the second slope 392 and the facing surface facing the second slope 392 in the mounting portion. Has been done. More specifically, the facing surfaces shown in FIGS. 7 and 9 are also inclined slopes, and accordingly, the mounting space 395 presents 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 variation examples, the contour shape of the mounting space 395 also changes as the tilt angle of the mounting 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, i.e., there is no space between the first slope 391 and the second slope 392 shown in FIG. 3, and the mounting holder 32 accordingly. The inclined end surface in the −Z axis direction (corresponding to the position of the second inclined surface 392) is defined as the mounting surface 39, and the space between the inclined end surface and the mounting portion is defined as 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, a movable member 23 is provided on the side of the case 2 facing the mounting surface 39, and the movable member 23 includes an elastic support portion 231, a rotating portion 232, and a joint portion 233. Specifically, an 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 the 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, so that the movable member 23 is rotated. It rotates 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, the elastic support portion 231 is also connected to the operation portion 234, the external force F is applied to the operation portion 234, and then the operation portion 234 transmits the external force F to the elastic support portion 231. 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 the force receiving portion 2311, and the force receiving portion 2311 in the present embodiment is an inclined surface, and hereinafter, the force receiving surface. The force receiving surface is perpendicular to the direction in which the joint portion 233 operates when the ink cartridge is taken out (operating direction S shown in FIG. 6), and the ends of the force receiving surface separated from the case are the −Z axis and + X. Tilt in the direction of the axis. When it is necessary to take out the ink cartridge, 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 the joint portion with the elastic support portion 231 in the Z-axis direction. It is located between the 233, that is, between the force receiving portion 2311 and the joint portion 233, and in this case, the direction of the external force F coincides with the operating direction S, so that the joint portion 233 and the mounting surface 39 And contribute to the relative extraction. Among them, the elastic support portion 231 and the joint portion 233 are located 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 directions. The operating direction S of the joint portion 233 is along the −Z axis and the −X axis direction, that is, the operating direction S is the tangential direction at the joint portion 233 in a circle formed by the joint portion 233 rotating about the rotating portion 232. Therefore, the joint portion 233 and the mounting surface 39 can be more easily separated.

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 machining errors and assembly errors, if the error in the joining position at the time of joining the joint portion 233 and the mounting surface 39 is large, the tip 26 deviates from the original position and the tip 26 and the contact pin 31 have poor contact. Since there is a risk, the joint portion 233 is closer to the chip 26 than the rotating portion 232, so that the positional error of the chip 26 is minimized.

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 located 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 the contact between the chip 26 and the contact pin 31 is poor. Can be avoided. Similarly, in the Z-axis direction, the chip 26 is located 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, the distance between the ink supply port 21 and the joint portion 233 in the examples of FIGS. 8 to 9 is the distance between the ink supply port 21 and the joint portion 233 in the examples of FIGS. The distance D1 between the force receiving portion 2311 and the rotating portion 232 in the examples of FIGS. 8 to 9 is smaller than the distance, and the distance D1 between the force receiving portion 2311 and the rotating portion 232 in the examples of FIGS. The distance D2 between the joint portion 233 and the rotating portion 232 in the examples of FIGS. 8 to 9 is larger than the distance D2 between the joint portion 233 and the rotating portion 232 in the examples 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. Since the arm in FIGS. 8 to 9 is relatively long, the ink cartridge can be taken out even with a small external force F, and the ink cartridge can be taken out easily.

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 example, the rotating portion 232 may be omitted. In response to this, when it is necessary to take out the ink cartridge, the elastic support portion 231 is still subjected to the external force F, and the elastic support portion 231 receives the external force to drive the compression of the elastic member 24, thereby driving the compression of the elastic member 24 as a whole. Moves in the −Z axis direction to give an acting force in the −X axis direction to the ink cartridge, and the entire ink cartridge moves in the −X axis direction. In this case, the contact pin 31 gives the ink cartridge an elastic force in the + Z-axis direction, so that the ink cartridge flips up 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.

It is a facing surface facing the mounting surface in the portion, and the space between the first slope 391 and the facing surface is defined as the mounting space 395.

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. Connected, that is, the mounting surface 39 is a slope extending over the entire mounting portion in the Y-axis direction, and accordingly, the space between the end surface (not shown) of the mounting surface 39 in the −Z axis direction and the mounting portion. Is the 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 stages of slopes (not shown), and accordingly, a plurality of mounting surfaces may be formed by the plurality of stages of slopes and the mounting portion. The 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。 Further, any of the mounting surfaces 39 according to the above-described embodiment can form a mounting space 395 together with the mounting portion, and those skilled in the art can refer to the schematic views of the configurations shown in FIGS. It is possible to understand how the joint portion 233 and the mounting space 395 are engaged with each other. Specifically, in the above-described embodiment, the mode of taking out the ink cartridge from the mounting portion is similar to that of the examples shown in FIGS. 7 and 9, and thus does not overlap here.

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 an applied portion 235, an elastic support portion 231, a joint portion 233, and a sliding portion 236, and is subjected to an applied force. The portion 235 is provided so as to face the rotary lever 34, the urged portion 235 can be moved by pushing force by the rotary lever 34, and the elastic member 24 is provided between the elastic support portion 231 and the case 2. There is. 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 the mounting holder is provided with a first slope 391 and a second slope 392. In this embodiment, the first slope 391 itself is the mounting surface 39, a mounting 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 closer to the ink cartridge, the far end 394 is farther from the ink cartridge, and the far end 394 is in the + Z axis direction. 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 mounting space 395 is the first slope 391, 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.

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 rotary lever 34 includes a pressing portion 342 and a hand pushing portion 343, and the pressing portion 342 is provided so as to face the applied portion 235, and the pressing portion 342 is used when the ink cartridge is taken out. The portion of the movable member 23 that applies an external force to the applied portion 235, and the hand push portion 343 is a portion that is operated by the user when the ink cartridge is taken out from the mounting portion. Since the external force is applied to the rotary lever 34, it can be better transmitted to the applied portion 235, 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, while the ink cartridge is being taken out, the user applies an external force G to the hand pushing portion 343 of the rotary lever 34, and the pressing portion 342 acts on the urged portion 235 by the rotational action of the rotary lever 34. When the applied force H is applied to the urged portion 235 in contact and the urged portion 235 is located in the upper half of the movable member 23, the point A (the contact portion between the lower part of the movable member 23 and the case 2) is rotated. A central moment is generated. The generated moment is a counterclockwise moment M1 centered on point A, and the moment may cause the movable member 23 to come off, or the position of the joint 233 may change due to severe wear of point A. 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 the acting force J generates a clockwise moment M2 centered on the point A. , M2 and M1 have an canceling action.

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 applied portion 235, the applied portion 235 can rotate around the rotation fulcrum (point A) by being pushed by the rotary lever 34. The joint portion 233 is closer to the rotation fulcrum (point A) than the applied portion 235, that is, the applied portion 235 is farther from the rotation fulcrum than the joint portion 233. In FIGS. 12 and 15, the distance D2 from the urged portion 235 to the point A is longer than the distance D1 from the joint portion 233 to the point A. During the removal of the ink cartridge, it is necessary to resist the frictional force between the joint portion 233 and the first slope 391 and the frictional force between the movable member 23 and the case 2, so that the joint portion 233 and the first slope 391 When the frictional force between the movable members 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 is D3 in the Z-axis direction, the distance between the acting force H and the rotation fulcrum is D4, and the distance between the joint 233 and the rotation fulcrum is D4 in the X-axis direction. The distance is D5. In FIGS. 11 to 13, it is preferable that D1 = 6.82 mm, D2 = 13.48 mm, D3 = 5.1 mm, D4 = 6.22 mm, and the ratio of D1 to D2 is smaller than 0.6. In FIGS. 14 to 15, it is preferable that 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 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。 In FIGS. 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. Therefore, in FIGS. 14 to 15, the joint portion 233 is joined. Closer to 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 variations 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 the mounting surface 39, and the second slope 392 is a part of the mounting portion. (That is, the facing surface corresponding to the mounting surface in the mounting portion), and correspondingly, 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 mounted in the case 2, and with reference to FIG. 16, the movable member 23 is mounted in the case 2 and the sliding portion 236 is mounted in the case 2. (It cannot be seen in FIG. 11 due to the line of sight), whereas the elastic member 24 in FIG. 7 and the elastic member 24 in FIG. 11 can be seen in comparison with FIGS. 7 and 11. Unlike this, the elastic member 24 in FIG. 7 is provided in the Z-axis direction, while the elastic member 24 in FIG. 11 is provided in the X-axis direction. With reference to the installation mode of the elastic member 24 in the embodiment shown in FIG. 11, when it is necessary to take out the ink cartridge, an external force G is applied to the rotary lever 34, and the external force received by the rotary lever 34 is applied to 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, and then the joint portion. The 233 is pulled out 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 taken out 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 variation, 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 members 23 differ 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. The joint portion 233 in FIG. 17 is a rod-shaped object extending in the + X-axis direction, and a massive convex portion is formed at the end of the rod-shaped object in the + X-axis direction. To. Those skilled in the art can understand the following. That is, the engagement method between the movable member 23 and the mounting space 395 shown in FIG. 17 is similar to the engagement method between the movable member 23 and the mounting space 395 in FIG. 16, except that the strength of the movable member 23 shown in FIG. Is higher than the movable member 23 in FIG. 16, and correspondingly, the method of attaching and removing the ink cartridge to which the movable member 23 is attached in FIG. 17 is similar to that of the third embodiment, and thus 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 portion 234, a rotating portion 232, and a joint portion 233, and the movable member 23 is connected to the case 2 via the rotating portion 232. The operation unit 234 is driven by receiving an external force so that the movable member 23 rotates around the rotating unit 232. Specifically, the movable member 23 shown in FIG. 18 is provided with two joints 233 in the Y-axis direction. Those skilled in the art can understand that the object of the present invention can be achieved with one joint 233 or a plurality of joints 233. More specifically, the ink cartridge to which the movable member 23 in FIG. 18 is attached can be similarly attached to the mounting portion, and the movable member 23 can engage with the mounting surface 39 in any of the above embodiments. In response to this, when it is necessary to take out the ink cartridge, an acting force is applied to the operation unit 234 in the -X-axis direction, and after the movable member 23 rotates in the -X-axis direction, the movable member 23 and the mounting surface are applied. The ink cartridge is separated from the 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 rotating portion 232 in the X-axis direction, and the joint portion 233 is located between the operation portion 234 and the rotating portion 232 in the Z-axis direction. By locating, the movable space of the movable member 23 is reduced.

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 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. The chip 26 is located between the ink supply port 21 and the joint 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 them, in the direction of the X-axis, 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 unit 234 and the joint portion 233 is D1, the distance between the operation unit 234 and the rotating unit 232 is D2, and the distance between the operation unit 234 and the chip 26 is D3. In FIG. 19, D1 = 9.19 mm, D2 = 16.76 mm, D3 = 23.07 mm, and in FIG. 21, D1 = 20.75 mm, D2 = 23.16 mm, 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 mounting surface 39 is not provided on the rotary lever 34, the influence of the operation of the rotary lever 34 on the joint portion 233 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 type of prior art ink cartridge (see description in Chinese application CN200710146624.4 for details). The ink cartridge of the prior art includes a negative pressure chamber 102 and an ink chamber 103, and in the negative pressure chamber 102, the negative pressure inside the ink cartridge is controlled by using the negative pressure sponge as a negative pressure mechanism. However, as the demand for the amount of ink in the ink cartridge of the user increases, the volume of the negative pressure chamber 102 is reduced and the volume of the ink chamber 103 is increased by research and development on a new material of the negative pressure sponge. Can be done. By introducing gas from the intake port 104 of the ink cartridge so as to further stabilize the negative pressure inside the ink cartridge, the gas inside the ink cartridge is made uniform. Specifically, as shown in FIG. 22, the ink cartridge of the prior art is sequentially divided into an air chamber 101, a negative pressure chamber 102, and an ink chamber 103 in the + X axis direction, and 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 ink cartridge technology, the manufacturer positions the ink supply port near 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 area of the ink cartridge on the −X axis side of the ink supply port is not used for ink storage. From this technical issue, there is still space for the amount of ink in the ink cartridge to expand.

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。 Further, FIG. 24 shows a fifth embodiment. The X-axis, Y-axis, and Z-axis of this embodiment coincide with the X-axis, Y-axis, and Z-axis of the first embodiment. An air chamber 251, a negative pressure chamber 252, a first ink chamber 253, and a second ink chamber 254 are provided in the case 2 of the ink cartridge. The first ink chamber 253 and the second ink chamber 254 constitute the ink chamber of the ink cartridge in each of the above-described embodiments. 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. The 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 the negative pressure sponge, and the ink supply port 21 is filled with the ink supply port sponge. Preferably, the densities of the ink supply sponge and the negative pressure sponge match, which prevents the printer from printing wastefully or dropping ink during standby due to the difference in both densities. .. As can be seen by comparing FIG. 22 and FIG. 24, the air chamber 251 and the negative pressure chamber 252 and the first ink are partially formed in the Y-axis direction of the case 2 in FIG. 24 as compared with the conventional technique shown in FIG. 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, in the X-axis direction, the ink chamber extends over the entire case 2 of the ink cartridge.

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。 Further, 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 becomes insufficient. As one suitable idea, the width of the ink cartridge in the Y-axis direction is D, the width of at least a part of the first ink chamber 253 in the Y-axis direction is D 1 , and the width of the negative pressure chamber 252 in the Y-axis direction is D 2. When this is done, D 1 ≤ D / 3 and D 2 ≥ 2 D / 3. Specifically, if the widths of the first ink chamber 253 in the + X-axis direction are not uniform, D 1 is the narrowest portion of the first ink chamber 253 in the Y-axis direction, and the + X of the first ink chamber 253. When the width in the axial direction is uniform, it is preferable that the width in the Y-axis direction of the first ink chamber 253 is 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。 Further, the first ink chamber 253 includes a first portion 2531 and a second portion 2532 that are sequentially distributed in the + X-axis direction, and as shown in FIG. 24, the width of the first portion 2531 is the first in the Y-axis direction. Larger than the width of the two portions 2532, 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 second portion 2532 is provided with a communication port 256 between the second portion 2532 and the second ink chamber 254. The portion 2532 can communicate the first portion 2531 and the second ink chamber 254, and such a design can achieve the object of fully utilizing the space of the first ink chamber 253. More specifically, as shown in FIG. 25, the ink cartridge in the fifth embodiment is also provided with the intake port 255, and its operation is similar to that of the conventional ink cartridge shown in FIG. 22, so that there is no overlap here. ..

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。 Further, referring to FIGS. 27 and 28, the first ink chamber 253 is communicated with the ink supply port 21 via the first passage 257, and the second ink chamber 254 is communicated with the ink supply port 258 via the second passage 258. It is communicated with 21 and the negative pressure chamber 252 is communicated with the ink supply port 21 via the third communication passage 259. Specifically, as can be seen with reference to FIG. 24, the D 1 is the width of the second portion 2532, and accordingly, the shape of the first passage 257 is an elongated slit. The first communication passage 257 allows the first ink chamber 253 to directly communicate with the ink supply port 21, whereby ink can be supplied to the ink supply port sponge. Then, when the printer prints continuously, it is possible to prevent an ink supply failure due to insufficient absorption capacity of the negative pressure sponge. Since the first passage 257 is long and thin, it is possible to prevent the ink from dropping when the ink cartridge is on standby.

以上、本発明の具体的な実施例について記述しました。理解すべきことは、本発明が上述した特定の実施形態に限られず、当業者であれば特許請求の範囲でさまざまの変形や変更を実施可能であり、本発明の実質内容に影響を与えない。 The specific examples of the present invention have been described above. It should be understood that the present invention is not limited to the specific embodiments described above, and a person skilled in the art can make various modifications and changes within the scope of the claims and does not affect the substance of the present invention. ..
