Description
本考案は、インクカートリッジを記録装置のホルダに安定的に収容し且つインクカートリッジに備えられる情報記憶媒体の接点と記録装置のインクカートリッジを収容するホルダに備えられたコネクタとを確実に接触できる第2係止部材を備えたインクカートリッジに関する。 According to the present invention, the ink cartridge can be stably accommodated in the holder of the recording apparatus, and the contact of the information storage medium provided in the ink cartridge and the connector provided in the holder accommodating the ink cartridge of the recording apparatus can be reliably contacted. The present invention relates to an ink cartridge having two locking members.
インクジェット記録ヘッドを備えた記録装置のホルダに着脱可能にインクカートリッジを搭載した記録装置においては、印刷時のホルダの移動によるインクカートリッジのホルダからの抜け出しの防止及びインクカートリッジに備えられた情報記憶媒体の接点と記録装置のインクカートリッジを収容するホルダに備えられたコネクタとの確実な接触が必須であるとともに、外部操作により記録装置とインクカートリッジとの着脱を容易に行えるような係止機構が備えられている。 In a recording apparatus in which an ink cartridge is detachably mounted on a holder of a recording apparatus provided with an ink jet recording head, the ink cartridge is prevented from coming out of the holder due to movement of the holder during printing, and an information storage medium provided in the ink cartridge In addition, a reliable contact between the contact of the recording device and the connector provided in the holder for accommodating the ink cartridge of the recording apparatus is essential, and a locking mechanism is provided so that the recording apparatus and the ink cartridge can be easily attached and detached by an external operation. It has been.
このような係止機構は、特許文献1において、インクジェット記録装置の走査キャリッジに搭載されたホルダに備えられたコネクタと、インク収納容器の底面と正面の稜部に形成された傾斜面に配置された接点とを、インク収納容器の回転動作を利用して接続させるための第2係合部6,306を備えた支持部材3、303を設けたインク収納容器に関して開示されている。該文献の図3及び図4には、正面下方に形成されて上方に湾曲して伸びる支持部材3突部が、図12には正面と上面の稜部に形成されて下方に湾曲して伸びる支持部材303突部が開示されている。 In Patent Document 1, such a locking mechanism is disposed on a connector provided on a holder mounted on a scanning carriage of an ink jet recording apparatus, and an inclined surface formed on a bottom surface and a front ridge portion of an ink storage container. The ink storage container is provided with support members 3 and 303 having second engaging portions 6 and 306 for connecting the contact points to each other using the rotation operation of the ink storage container. 3 and 4 of the document, the protrusion of the support member 3 that is formed in the lower part of the front and curved upwards, and in FIG. 12, the protrusion of the support member 3 that is formed in the ridges on the front and upper surfaces and curved and extends downwards. A support member 303 protrusion is disclosed.
特許文献2には、特許文献1の支持部材をラッチレバーとして開示している。即ち、インクジェット用のインクタンクにおいて、インクタンクの使用状態で底となる部分に配されたインクを供給するためのインク供給口と、前記インクタンクの一側面の一部に設けられた、前記ホルダに形成された第1係止部と係合する第1係合部と、前記第1係合部が設けられた側面に対する他側面に対して弾性的に設けられた、前記ホルダに形成された第2係止部に係合する第2係合部を備えたラッチレバーと、を備えたことを特徴とするインクタンクが開示されている。また、特許文献2の〔0108〕には、「インクタンク30の他端側(ラッチレバー32aが設けられている側)の底壁をモノカラーホルダ60の開口に向けて付勢する付勢手段として、図18に示すようなポップアップバネ68を設け、そのバネ力を利用して、インクタンク30のラッチレバー32a側の端部を持ち上げてもよい。」と記載されている。 Patent Document 2 discloses the support member of Patent Document 1 as a latch lever. That is, in an ink jet ink tank, an ink supply port for supplying ink disposed in a bottom portion when the ink tank is in use, and the holder provided on a part of one side surface of the ink tank A first engagement portion that engages with the first locking portion formed on the first engagement portion; and the holder that is elastically provided with respect to the other side surface with respect to the side surface on which the first engagement portion is provided. An ink tank comprising: a latch lever having a second engaging portion that engages with the second locking portion is disclosed. Also, in [0108] of Patent Document 2, “a biasing means for biasing the bottom wall of the other end side (the side where the latch lever 32 a is provided) of the ink tank 30 toward the opening of the monochromatic holder 60 is disclosed. As shown in FIG. 18, a pop-up spring 68 as shown in FIG. 18 may be provided, and the end of the ink tank 30 on the latch lever 32a side may be lifted using the spring force.
しかし、上記特許文献1の図4に見られるように、係止部材は記録装置への装着時に、図4bのようにインクカートリッジの内側へ、脱着時には図4cのように外側に屈曲し、その応力が係止部材の基部(壁との溶着部)にかかり、曲げ応力に弱い材料の場合は折損してしまうことがあった。その対策として、部材の厚みを厚くしたり剛性の大きい材料を使ったりした場合には、係止部材の反発力が強過ぎることによって、キャリッジとインク収納容器との間に拡開する方向の力がかかり、走査キャリッジに搭載されたホルダに備えられたコネクタとインク収納容器の底面と正面の稜部に形成された傾斜面に配置された接点とが接触不良を起こす可能性があった。図12のように突部が上方から下方に湾曲して伸びる場合も係止部材の付け根で折損したり、またキャリッジとインク収納容器との間に拡開する方向の力がかかる点で上記と同様である。 However, as shown in FIG. 4 of Patent Document 1, the locking member bends to the inside of the ink cartridge as shown in FIG. 4b when attached to the recording apparatus, and to the outside as shown in FIG. Stress is applied to the base portion (welded portion with the wall) of the locking member, and in the case of a material that is weak against bending stress, it may break. As a countermeasure, when the thickness of the member is increased or a material with high rigidity is used, the repulsive force of the locking member is too strong, causing the force to expand between the carriage and the ink container. Therefore, there is a possibility that a contact failure is caused between the connector provided on the holder mounted on the scanning carriage and the contact disposed on the inclined surface formed on the bottom surface of the ink storage container and the front ridge. As shown in FIG. 12, even when the protrusion curves and extends downward from above, it breaks at the base of the locking member, and the above point is that a force in the expanding direction is applied between the carriage and the ink storage container. It is the same.
また、特許文献2の(0100)段には、「抜け止め爪32dとは反対側の外壁である他端面に、下端部を弾性的に支持されたラッチレバー32aが一体的に設けられている。ラッチレバー32aは、インクタンク30の外側上方に向かって傾斜し、……インクタンク30がモノカラーホルダ60に装着された状態では、ラッチレバーガイド溝60hに押圧されて図14に示した矢印C方向にたわみ、ラッチレバー32aに形成されたラッチ爪32eが、ラッチレバーガイド溝60hに形成されたラッチ爪係合穴60jに係合される。」と記載されている。即ち、図23のように本インクカートリッジの記録装置への装着時あるいは脱着時には、ラッチレバーに応力がかかった状態であり、これを繰り返すことによって、ラッチレバーの基部(ラッチレバーと側壁との溶着部:以下同様)の折損の可能性があること及びカラーホルダ160とカラーインクタンク140のラッチレバーが形成された壁との間にラッチレバーのたわみ応力による拡開方向の力が働くことは上記文献1と同様である。更に特許文献2の(0108)段の記載から、インクタンクの装着状態においてはラッチ爪32eにポップアップバネ68の下方からの押圧力がかかり、その押圧力がラッチレバー32aの基部に集中してラッチレバー基部の折損の要因になること及び該インクタンク底壁とホルダーとの間にポップアップバネによる拡開方向の力が働くことになり、コネクタを備えたホルダとインク収納容器の底面と正面の稜部に形成された傾斜面に配置された接点を有するインクカートリッジの場合は、接点とコネクタとが接触不良を起こす可能性がある。 Further, in the (0100) stage of Patent Document 2, “a latch lever 32a having an elastically supported lower end portion is integrally provided on the other end surface which is the outer wall opposite to the retaining claws 32d. The latch lever 32a is inclined upward and outward from the ink tank 30. When the ink tank 30 is mounted on the monocolor holder 60, the latch lever 32a is pressed by the latch lever guide groove 60h and the arrow shown in FIG. The latch pawl 32e formed in the latch lever 32a and deflected in the C direction is engaged with the latch pawl engaging hole 60j formed in the latch lever guide groove 60h. " That is, as shown in FIG. 23, when the ink cartridge is attached to or detached from the recording apparatus, the latch lever is under stress. By repeating this, the base of the latch lever (welding between the latch lever and the side wall is performed). Part: the same shall apply hereinafter) and that the force in the expanding direction due to the bending stress of the latch lever acts between the color holder 160 and the wall of the color ink tank 140 where the latch lever is formed. This is the same as Document 1. Further, from the description of stage (0108) of Patent Document 2, when the ink tank is mounted, the latch claw 32e is pressed from below the pop-up spring 68, and the pressing force is concentrated on the base of the latch lever 32a and latched. This may cause breakage of the lever base, and a force in the expanding direction by a pop-up spring acts between the bottom wall of the ink tank and the holder, and the bottom and front edges of the holder provided with the connector and the ink storage container In the case of an ink cartridge having a contact disposed on an inclined surface formed in the portion, there is a possibility that a contact failure occurs between the contact and the connector.
別の観点から検討すると、特許文献1のラッチレバーの構成は、成形品の精度に左右されるため、特許文献2のようにヘッドのインク供給管にインクカートリッジの供給部を当接せしめる程度は出来ても、特許文献1の場合のように複数の電気的接続を行う場合は、接点の製造精度がばらついたりするとコネクタを備えたホルダに対して、接点とコネクタとが接触不良を起こす場合が見られた。 Considering from another viewpoint, since the configuration of the latch lever in Patent Document 1 depends on the accuracy of the molded product, the degree to which the ink cartridge supply portion is brought into contact with the ink supply pipe of the head as in Patent Document 2 is limited. Even if it is possible, when a plurality of electrical connections are made as in Patent Document 1, if the manufacturing accuracy of the contacts varies, the contact and the connector may cause poor contact with the holder provided with the connector. It was seen.
本考案の主たる課題は、インクカートリッジ自体に新たな位置決め能力をもたらすことで、インクカートリッジを記録装置のホルダに安定的に収容し且つインクカートリッジを記録装置のホルダに装着するに際して、インクカートリッジに形成された情報記録装置の接点と記録装置のホルダに形成されたコネクタとを確実に接触させることができるアーム型ラッチレバー付(もしくは取り付け可能)インクカートリッジを提供することである。本考案の別の課題は、主たる課題に加えて、強度や弾性力あるいは押圧力をより効果的に実用化するための構造などを備えた新しきインクカートリッジを提供することである。また、さらに本考案の更なる課題は、ラッチレバーの強度を向上できる構成であり、その強度をさらに向上できる部分を備えた新しいインクカートリッジを提供することである。 The main problem of the present invention is to provide a new positioning capability for the ink cartridge itself, so that the ink cartridge can be stably accommodated in the holder of the recording apparatus and formed in the ink cartridge when the ink cartridge is attached to the holder of the recording apparatus. It is an object of the present invention to provide an ink cartridge with an arm type latch lever (or attachable) that can reliably contact a contact of an information recording apparatus and a connector formed on a holder of the recording apparatus. Another object of the present invention is to provide a new ink cartridge having a structure for practically and effectively using strength, elastic force or pressing force in addition to the main problem.

Here, the ridge region is not a slope but may be the front surface, the bottom surface, or the side surface, but the vicinity of the ridge portion between the bottom surface 3b and the front surface 3c.
第2係止部材10は、図2に示す位置関係を満足し、図に示したように、後面に第2係止部材の支持部10aを、上面側には上面側アーム部10bを、前面側にはラッチ爪10cとその上方に操作部10dとさらにこれらの上方に戻り防止突起10eが前面側アーム部10fに設けられていて、図に示されるように、これらは箱型容器の外形に沿って一部の接触を除いては小型容器から離間している。ここで、2つの屈曲部を、後面側屈曲部10g、前面側屈曲部10hとする。従って、この第2係止部材10は後面の上部10aに基点(本考案の支持部の一例)と、後面3dの一部から上面3aの全体及び前面3cの一部に沿って延在するアーム部を有し、その先端は前面3cの下部の傾斜面3gより手前で且つホルダ第2係止部104と係合できる位置まで伸びている構成をもつ。このホルダ第2係止部104は本例では突起であるが周知の開口や凹部でも良く、上記第2係止部材の係止は周知のラッチ爪としたが、ホルダ第2係止部104の構成に対応して、係合できるものであればどのような構成でも良い。尚、後面3dの下方にはホルダに形成されたホルダ第1係止部材101と係合する第1係止部材9が設けられている。このホルダ第1係止部101は本例では突起であるが周知の開口や凹部でも良く、上記第1係止部材は周知の突起としたが、ホルダ第1係止部101の構成に対応して、係合できるものであればどのような構成(たとえば後面に位置する第2係止部材の支持部10aを上面の中央部分に移動し、この第2係止部材の逆の構成にするか、特許文献1,2のラッチレバー構成そのもの等)でも良く、前記アーム部を下方まで延長して、ここに設けても良い。 The second locking member 10 satisfies the positional relationship shown in FIG. 2, and as shown in the figure, the second locking member support portion 10a is provided on the rear surface, the upper surface side arm portion 10b is provided on the upper surface side, and the front surface side. On the side, a latch claw 10c, an operation portion 10d above the latch claw 10c, and a return prevention projection 10e above the operation portion 10d are provided on the front arm portion 10f. It is spaced apart from the small container except for some contact along. Here, the two bent portions are referred to as a rear side bent portion 10g and a front side bent portion 10h. Accordingly, the second locking member 10 has a base point (an example of the support portion of the present invention) on the rear surface upper portion 10a, and an arm extending from a part of the rear surface 3d along the entire upper surface 3a and a part of the front surface 3c. And has a configuration in which the front end extends to a position in front of the inclined surface 3g of the lower portion of the front surface 3c and a position where it can engage with the holder second locking portion 104. Although the holder second locking portion 104 is a protrusion in this example, it may be a well-known opening or recess. The second locking member is locked by a well-known latch claw. Any configuration may be used as long as it can be engaged in accordance with the configuration. A first locking member 9 that engages with a holder first locking member 101 formed on the holder is provided below the rear surface 3d. Although the holder first locking portion 101 is a protrusion in this example, it may be a well-known opening or recess, and the first locking member is a well-known protrusion, but corresponds to the configuration of the holder first locking portion 101. As long as it can be engaged, what kind of configuration (for example, the support portion 10a of the second locking member located on the rear surface is moved to the center portion of the upper surface, and the configuration opposite to that of the second locking member is set) The latch lever structure itself of Patent Documents 1 and 2 may be used, and the arm portion may be extended downward and provided here.
さらに、上壁3aの中央部には上面アーム部10bを下方から支持する突部11が、前面10cの上方には移動阻止部材13が、第2係止部材10の先端部近傍には記録装置のホルダ第2係止部材104と係合する外向き(箱型容器から見て)のラッチ爪10cが、第2係止部材10のラッチ爪10c近傍の上部には本インクカートリッジ1の着脱のための操作部材10dが強度を高めることと操作面を確保するために前面略直方体状の形状に形成されている。ここで、突起11は箱型容器の上面に設けたが、上面アーム部自体が持っていても良く、これら両者がそれぞれ持っていても良い。無論突起形状でなく、厚みを変化させた滑らかな形状でも良い。 Furthermore, a protrusion 11 that supports the upper arm portion 10b from below is provided at the center of the upper wall 3a, a movement preventing member 13 is provided above the front surface 10c, and a recording device is provided near the tip of the second locking member 10. An outwardly-facing latch claw 10c (as viewed from the box-shaped container) that engages with the holder second locking member 104 is attached to the upper portion of the second locking member 10 near the latch claw 10c. The operation member 10d is formed in a substantially rectangular parallelepiped shape in order to increase the strength and secure the operation surface. Here, the protrusion 11 is provided on the upper surface of the box-shaped container, but the upper arm portion itself may be provided, or both of them may be provided. Of course, it is not limited to the protruding shape, but may be a smooth shape having a changed thickness.
インクカートリッジ1を記録装置のホルダ100に挿入する手順は、まず第1係止部材9をホルダ第1係止部材101に係止させ、続いて上面側アーム部10bの前面3c側を下方へ押し込み、情報記憶媒体の接点8とホルダ100のコネクタ103を接触させた状態でラッチ爪10cとホルダ第2係止部材104を係止させる。 In order to insert the ink cartridge 1 into the holder 100 of the recording apparatus, the first locking member 9 is first locked to the holder first locking member 101, and then the front surface 3c side of the upper surface side arm portion 10b is pushed downward. Then, the latch claw 10c and the holder second locking member 104 are locked while the contact 8 of the information storage medium and the connector 103 of the holder 100 are in contact with each other.
記録装置での走査時のインクカートリッジ1の激しい動きやインクカートリッジ装着時における正常位置からのわずかな傾きやずれなどによって、コネクタ104と情報記憶媒体8の接点との接続は、接触不良となることがある。この振動があっても本実施例においては、上記アーム部の構成があるので、情報記憶媒体の接点8は傾斜面3gに配置することによって、接点8は縦及び横の両方向からコネクタ103に対して押圧力を受けることが可能となり、コネクタ103と情報記憶媒体の接点8との接続がより一層確実となる。情報記憶媒体の接点8を前面3cに配置した場合は、横方向からの押圧力を受けるが、本実施例においては、上記アーム部の構成があるので、縦方向の移動をより確実に阻止できる。従って、本考案の上記載置面としては、縦及び横の両方向からの押圧力を受けやすくするため傾斜面が好ましく、複数の接点8を備える情報記憶媒体は傾斜面3gに配置されることが好ましい。 The connection between the connector 104 and the contact point of the information storage medium 8 becomes poor contact due to the intense movement of the ink cartridge 1 at the time of scanning in the recording apparatus or slight inclination or deviation from the normal position when the ink cartridge is mounted. There is. Even in the case of this vibration, in the present embodiment, since there is the structure of the arm portion, the contact 8 of the information storage medium is arranged on the inclined surface 3g, so that the contact 8 can be connected to the connector 103 from both the vertical and horizontal directions. Thus, it is possible to receive a pressing force, and the connection between the connector 103 and the contact 8 of the information storage medium is further ensured. When the contact 8 of the information storage medium is arranged on the front surface 3c, it receives a pressing force from the lateral direction. However, in this embodiment, since there is the configuration of the arm portion, the vertical movement can be more reliably prevented. . Therefore, the mounting surface described above of the present invention is preferably an inclined surface in order to easily receive a pressing force from both the vertical and horizontal directions, and the information storage medium including the plurality of contacts 8 is disposed on the inclined surface 3g. preferable.
第2係止部材10は後面の上部10aに支持部を有し後面3dと上面3aの稜部近傍で屈曲して上面に沿って延在し、上面3aと前面3cの稜部近傍で再度屈曲し前面3cに沿って延在し、その先端は前面下部の傾斜面3gより手前で且つホルダ第2係止部材104と係合できる位置まで伸びている。第2係止部材10は、インクカートリッジの稜部で上面3a、後面3cに沿って屈曲することによって、概ね箱型のインクカートリッジの形状を保持でき、これを製品化する際に嵩張らない簡潔な包装形態に仕上げることができるので好ましい。 The second locking member 10 has a support portion on the upper portion 10a of the rear surface, bends in the vicinity of the ridge portion of the rear surface 3d and the upper surface 3a, extends along the upper surface, and bends again in the vicinity of the ridge portion of the upper surface 3a and the front surface 3c. It extends along the front surface 3c, and its tip extends to a position where it can be engaged with the holder second locking member 104 before the inclined surface 3g at the lower front surface. The second locking member 10 is bent along the upper surface 3a and the rear surface 3c at the ridge portion of the ink cartridge, so that the shape of the substantially box-shaped ink cartridge can be maintained. Since it can finish in a packaging form, it is preferable.
前面の頂部近傍には移動阻止部材13が容器の全幅に渡って板状突起として形成されている。この移動阻止部材13は容器の幅の少なくとも中央に存在することが好ましいが、後述する戻り防止突起10eの構成次第ではあるが、全幅でなくともよい。また前面アーム部10fの前面10c側の上部には、戻り防止突起10eが移動阻止部材13より下方に位置するように形成されている。このように形成することによって、インクカートリッジの脱着に際し、ホルダ第2係止係止部材104とラッチ爪10cの係止を外すと、前面アーム部10fは上面アーム部10bの板バネ的な復元力によって上方に引き上げられるが、移動阻止部材13に戻り防止爪10cが係合されて、上面アーム部10bと上面3aとは、それ以上離れることはなく、第2係止部材10を摘んでインクカートリッジ1全体をホルダ100から引き出すことができるという効果がある。同時に、これらの構成によって、過度の負荷が上向きにかかってもこれらの係合関係は外れることが無いので、ラッチ爪が損傷することが無い。本実施例の場合、移動阻止部材13が容器の全幅に渡って板状突起として形成されているので、第2係止部材10(後面の上部10aに基点(本考案の支持部の一例)と、後面3dの一部から上面3aの全体及び前面3cの一部に沿って延在するアーム部を有し、その先端は前面3cの下部の傾斜面3gより手前で且つホルダ第2係止部104と係合できる位置まで伸びている構成をもつ)は、側面からスライドして装着される部材であることが好ましい。 Near the top of the front surface, a movement preventing member 13 is formed as a plate-like protrusion over the entire width of the container. The movement preventing member 13 is preferably present at least in the center of the width of the container. However, the movement preventing member 13 may not be the full width depending on the configuration of the return preventing protrusion 10e described later. Further, a return prevention protrusion 10e is formed on the upper portion of the front arm portion 10f on the front surface 10c side so as to be positioned below the movement blocking member 13. By forming in this way, when the ink cartridge is detached, the front arm portion 10f is restored to the plate spring-like restoring force of the upper arm portion 10b when the second holder locking member 104 and the latch claw 10c are unlocked. The return preventing claw 10c is engaged with the movement preventing member 13, and the upper surface arm portion 10b and the upper surface 3a are not further separated from each other. There is an effect that one whole can be pulled out from the holder 100. At the same time, because of these configurations, even if an excessive load is applied upward, these engagement relations are not released, so that the latch claws are not damaged. In the case of the present embodiment, since the movement preventing member 13 is formed as a plate-like projection over the entire width of the container, the second locking member 10 (the base point (an example of the support portion of the present invention) on the rear surface upper portion 10a) And an arm portion extending from a part of the rear surface 3d along the entire upper surface 3a and a part of the front surface 3c, the tip of which is in front of the lower inclined surface 3g of the front surface 3c and the holder second locking portion. 104 having a configuration extending to a position where it can engage with 104 is preferably a member that is slid from the side surface.
上壁3aには第2係止部材10を下方で支持する突部11が形成されている。インクカートリッジ1は記録装置のホルダへ装着時に第2係止部材10の上面側アーム部10bを下方に押しながら装着される。その際、突部11の頂部を支点として、上面側アーム部10bの前面側は下方への押圧力を受け、図3に示すように側面側アーム部10fが下方へ移動して、ラッチ爪10cがホルダの第2係止部材104に係止される。インクカートリッジ1の着脱時において、突部11の位置は、後面3d側に近づくほど上面側アーム部10の縦方向に移動する部分が長くなるために、ラッチ爪10cとホルダ第2係止部材104との係止力(弾性復帰力)は小さくなり、また前面側アーム部10fの横方向への移動距離は小さくなる。逆に突部11の位置が前面3c側に近づくほど上面側アーム部10の縦方向に移動する部分が短くなるために、ラッチ爪10cとホルダ第2係止部材104との係止力(弾性復帰力)は大きくなり、また前面側アーム部10fの前面側への移動距離は大きくなる。突部11の上面3b上の位置はどこであってもよく、また突部11は複数あってもよい。支持部の位置や数は上述を考慮して決定する設計事項である。 A protrusion 11 is formed on the upper wall 3a to support the second locking member 10 below. The ink cartridge 1 is attached to the holder of the recording apparatus while pressing the upper arm portion 10b of the second locking member 10 downward. At that time, with the top portion of the protrusion 11 as a fulcrum, the front side of the upper surface side arm portion 10b receives a downward pressing force, and the side arm portion 10f moves downward as shown in FIG. Is locked to the second locking member 104 of the holder. When the ink cartridge 1 is attached / detached, the position of the protrusion 11 is such that the portion of the upper arm portion 10 that moves in the vertical direction becomes longer as it approaches the rear surface 3d side. And the moving distance in the lateral direction of the front arm portion 10f is reduced. Conversely, as the position of the protrusion 11 approaches the front surface 3c side, the portion of the upper arm portion 10 that moves in the vertical direction becomes shorter, so that the locking force (elasticity) between the latch claw 10c and the holder second locking member 104 is reduced. Return force) is increased, and the distance of movement of the front arm portion 10f to the front surface is increased. The position of the protrusion 11 on the upper surface 3b may be anywhere, and there may be a plurality of protrusions 11. The position and number of the support portions are design matters that are determined in consideration of the above.
また突部11は無くてもよい。突部11がない場合は、インクカートリッジ1がホルダ100に装着された状態においては上面アーム部10bとインクカートリッジ1の移動阻止部材13の上部とが接触しその接触部が突部の役割を果たすが、設計段階で突部の位置を調整することが好ましいので、突部11を設けることが好ましい。 Further, the protrusion 11 may not be provided. When the protrusion 11 is not present, the upper arm portion 10b and the upper portion of the movement preventing member 13 of the ink cartridge 1 are in contact with each other and the contact portion serves as a protrusion when the ink cartridge 1 is mounted on the holder 100. However, since it is preferable to adjust the position of the protrusion at the design stage, it is preferable to provide the protrusion 11.
本インクカートリッジ1を記録装置のホルダ100へ装着した状態において、記録装置のホルダ100のホルダ第2係止部材側にインクカートリッジ1の前面3c側の底面3bを押し上げるようにポップアップバネが設けられている場合には、このポップアップバネによる下方からの押圧力を、ラッチ爪10cから上面アーム部10bおよび支持部10aに伝達され第2係止部材全体に分散されて受けることになり、ポップアップバネによる応力が一点に集中しないため第2係止部材の折損などの不具合が起こり難く、それによって安定的にインクカートリッジ1をホルダ100に保持できる。 In a state where the ink cartridge 1 is mounted on the holder 100 of the recording apparatus, a pop-up spring is provided on the holder second locking member side of the holder 100 of the recording apparatus so as to push up the bottom surface 3 b on the front surface 3 c side of the ink cartridge 1. In this case, the pressing force from below by the pop-up spring is transmitted from the latch claw 10c to the upper arm portion 10b and the support portion 10a and is distributed and received by the entire second locking member. Since the ink does not concentrate on one point, problems such as breakage of the second locking member hardly occur, so that the ink cartridge 1 can be stably held in the holder 100.
剛性を有する材料(プラスチックや板材金属でも良い)からなる上面アーム部10bは板バネ的な性質を有する。図3に示すように、インクカートリッジ1が記録装置のホルダ100に装着されラッチ爪10cとホルダ第2係止部材104が係止された状態において、上面アーム部10bの板バネ的な性質により、ラッチ爪10cには上向き(図3のA)の係止力(弾性復帰力)が作用している。そのため、傾斜面3gにおいてホルダ100のコネクタ104には接点8に対して上向きの押圧力が働くことになる。 The upper arm portion 10b made of a rigid material (which may be plastic or plate metal) has a leaf spring property. As shown in FIG. 3, in a state where the ink cartridge 1 is mounted on the holder 100 of the recording apparatus and the latch claw 10c and the holder second locking member 104 are locked, due to the leaf spring nature of the upper surface arm portion 10b, An upward locking force (elastic return force) acts on the latch claw 10c. Therefore, an upward pressing force acts on the contact 104 on the connector 104 of the holder 100 on the inclined surface 3g.
突部11の高さhは、高いほど前面アーム部10fの上下の移動距離が長くなるのでラッチ爪10cとホルダ第2係止部材104を係止させ易いが、上面アーム部10bが上壁3aから離れるので、第2係止部材10がインクカートリッジに固定し難くなる。また、高さhが低いほど前面アーム部10fの上下の移動距離が短くなるのでラッチ爪10cとホルダ第2係止部材104を係止できる範囲が狭くなり操作し難くなるが、上面アーム部10bが上壁3aと近接しているので、第2係止部材10はインクカートリッジに固定し易い。従って、高さhは0.2mm〜10mmであるが、より好ましくは1〜5mmである。 The higher the height h of the protrusion 11 is, the longer the vertical movement distance of the front arm portion 10f is. Therefore, the latch claw 10c and the holder second locking member 104 can be easily locked, but the upper arm portion 10b is formed on the upper wall 3a. Therefore, it is difficult to fix the second locking member 10 to the ink cartridge. Further, since the vertical movement distance of the front arm portion 10f becomes shorter as the height h is lower, the range in which the latch claw 10c and the holder second locking member 104 can be locked becomes narrow and difficult to operate, but the upper arm portion 10b. Is close to the upper wall 3a, the second locking member 10 is easily fixed to the ink cartridge. Accordingly, the height h is 0.2 mm to 10 mm, and more preferably 1 to 5 mm.
図4は、ホルダに装着前において上面側アーム部10bが、前面側の方が後面側より高い場合の、上面アーム部10bと前面アーム部10cの装着前後の状態を示している。装着前が図4の(10b−10e)であり装着後が(10b’―10e’)である。突部11は後面近傍に形成されており、図4のO点は突部11の位置を示す。係止前後における第2係止部材10の移動距離は、下方にL4、左方にL3である。第2係止部材は弾性復帰力のある部材なので、係止後(10b’―10e’)の状態においては上方にL4、右方にL3の力が働いている。即ち、傾斜面3gにおける接点8とコネクタ103は、第2係止部材によって、少なくとも上方にL4、右方にL3の力で押圧される。ホルダに装着前において上面側アーム部10bが上面3aと平行の状態にある場合、装着前後において図4の(10b’―10e’)から(10b’’―10e’’)に移動する。即ち、係止前後における第2係止部材の移動距離は、下方にL4、右方にL3であって、第2係止部材は係止後(10b’’―10e’’)の状態においては第2係止部材の弾性復帰力によって上方(接点8とコネクタの接触圧を強める方向)にL4、左方(接点8とコネクタの接触圧を弱める方向)にL3の力が働く。従って、本インクカートリッジ1においては、上面アーム部10bと上面3aとの間隔が、前面3a近傍の方が後面3d近傍よりも大きいことが好ましい。 FIG. 4 shows a state before and after mounting of the upper surface arm portion 10b and the front arm portion 10c when the upper surface side arm portion 10b is higher on the front surface side than the rear surface side before mounting on the holder. FIG. 4 shows (10b-10e) before mounting and (10b′-10e ′) after mounting. The protrusion 11 is formed near the rear surface, and the point O in FIG. 4 indicates the position of the protrusion 11. The moving distance of the second locking member 10 before and after locking is L4 downward and L3 to the left. Since the second locking member is a member having an elastic restoring force, in the state after locking (10b'-10e '), a force of L4 is applied upward and L3 is applied to the right. In other words, the contact 8 and the connector 103 on the inclined surface 3g are pressed by the second locking member at least with a force of L4 upward and L3 to the right. When the upper surface side arm portion 10b is in parallel with the upper surface 3a before being mounted on the holder, the arm moves from (10b′-10e ′) to (10b ″ -10e ″) in FIG. 4 before and after mounting. That is, the moving distance of the second locking member before and after locking is L4 downward and L3 rightward, and the second locking member is in the state after locking (10b ″ -10e ″). Due to the elastic restoring force of the second locking member, the force L4 is exerted upward (in the direction in which the contact pressure between the contact 8 and the connector is increased), and the force L3 is exerted in the left (in the direction in which the contact pressure between the contact 8 and the connector is weakened). Therefore, in the present ink cartridge 1, it is preferable that the distance between the upper surface arm portion 10b and the upper surface 3a is larger in the vicinity of the front surface 3a than in the vicinity of the rear surface 3d.
前面アーム部10fのラッチ爪10cの上方にインクカートリッジの着脱のための操作部10dが形成されている。操作部10dは、前面アーム部10fの外側向きに形成された面状体であって、外側へ突起した直方体形状の方が指で操作し易いので好ましい。 An operation portion 10d for attaching and detaching the ink cartridge is formed above the latch claw 10c of the front arm portion 10f. The operation portion 10d is a planar body formed outwardly from the front arm portion 10f, and a rectangular parallelepiped shape protruding outward is preferable because it can be easily operated with a finger.
第2係止部材基部10aにおいて、第2係止部材10と後面10dとが、インクカートリッジ1から取り外し可能に勘合して形成されている。本インクカートリッジ1を製品として包装する際、第2係止部材10をインクカートリッジ1から分離することによって、より自由な形状に包装できるという利点がある。 In the second locking member base portion 10 a, the second locking member 10 and the rear surface 10 d are formed so as to be detachable from the ink cartridge 1. When packaging the ink cartridge 1 as a product, the second locking member 10 is separated from the ink cartridge 1 so that there is an advantage that it can be packaged in a more free shape.
(その他の実施例)
上記本考案の最良の形態を用いながら、本考案の他の実施形態について説明する。本考案のアーム部を備えた第2係止部材は、インクカートリッジである箱型容器と別体にした装着部材とすることで、装着部にわずかな「ずれ」を発生させることができる。これは「カートリッジと一体成形したラッチレバーの付け根に集中して折れ曲がりを引き起こす応力」を分散或は拡散出来るので、好ましいものである。
(Other examples)
Another embodiment of the present invention will be described using the best mode of the present invention. The second locking member provided with the arm portion of the present invention is a mounting member that is separate from the box-shaped container that is an ink cartridge, so that a slight “displacement” can be generated in the mounting portion. This is preferable because it can disperse or diffuse the “stress that causes bending by concentrating on the base of the latch lever integrally formed with the cartridge”.
図5及び図6に示すインクカートリッジ1aは本考案の他の実施形態によるインクカートリッジである。この実施例は、本考案のアーム部を備えた第2係止部材の支持部が、箱型容器の側面にした部分と、これを達成するためのアーム部の構成を開示したものである。図5でわかるように、上記第2係止部材10は、上面3a近傍の一対の側面3e及び3fの夫々に凹部として形成された支持部10aと、上面に沿っていると共に側面3e及び3fに沿って水平に伸び前面3c側で一体化する上面側アーム部10bと、前面3cに沿って下方に屈曲する前面側アーム部10fと、前面側アーム部10fの先端に形成され記録装置のホルダと係止するラッチ爪10cと、ラッチ爪10cの上方に形成された操作部10dとを備え、上記移動阻止部材としてはアームの水平部分を移動阻止部材10eとして備えている。この実施例は、箱型容器の上面に対しては、係合しない構成であるので、箱型容器の側面に上面側アーム10bの下方への移動を阻止する下方阻止部材32を上記突部(上面に設けたもの)の機能を持つもので、上記押圧力を得るために上記アーム部の変形をもたらすものである。無論上面に沿うと共に上面を覆うカバー部分をこの第2係止部材に付加した構成も本考案の実施例になることは言うまでも無い。他の部分変更した構成は、本考案の技術的範囲内の変更であれば可能であり、本考案に含まれるものである。 The ink cartridge 1a shown in FIGS. 5 and 6 is an ink cartridge according to another embodiment of the present invention. In this embodiment, the support portion of the second locking member provided with the arm portion of the present invention is a portion formed on the side surface of the box-type container, and the configuration of the arm portion for achieving this is disclosed. As can be seen in FIG. 5, the second locking member 10 includes a support portion 10a formed as a recess in each of the pair of side surfaces 3e and 3f in the vicinity of the upper surface 3a, and the side surfaces 3e and 3f along the upper surface. A front surface side arm portion 10b extending horizontally along the front surface 3c side, a front surface side arm portion 10f bent downward along the front surface 3c, and a holder of the recording apparatus formed at the front end of the front surface side arm portion 10f, A latch claw 10c to be locked and an operation portion 10d formed above the latch claw 10c are provided, and the horizontal portion of the arm is provided as a movement blocking member 10e as the movement blocking member. In this embodiment, the upper surface of the box-shaped container is not engaged with the upper surface of the box-shaped container, and therefore the lower blocking member 32 that prevents the upper surface side arm 10b from moving downward is provided on the side surface of the box-shaped container. Provided on the upper surface), and the arm portion is deformed in order to obtain the pressing force. Of course, it is needless to say that a configuration in which a cover portion along the upper surface and covering the upper surface is added to the second locking member is also an embodiment of the present invention. Other partially modified configurations are possible within the technical scope of the present invention, and are included in the present invention.
