〔産業上の利用分野〕
本発明は、インクジェット記録装置にインクを供給する
為のインク供給容器の構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of an ink supply container for supplying ink to an ink jet recording apparatus.
（従来の技術〕 第３図に従来のインク供給容器の一例を示す。(Conventional technology) FIG. 3 shows an example of a conventional ink supply container.
図で８１が容器外壁で３２が、インク袋とインク吸収体

ている。In the figure, 81 is the outer wall of the container, and 32 is a partition wall that separates the ink bag from the ink absorber. This partition wall is completely fixed to the outer wall of the container by adhesive, and has sufficient airtightness. 34 is an ink absorber, which is generally made of a felt-like material with good liquid absorbency. This absorber is
It is provided for the purpose of absorbing ink other than that used for printing, for example, surplus ink when filling the head with ink at the start, and the ink is discharged from the recovery pipe 37. 33 is an ink bag, and ink is generally stored in a bag made of a laminated sheet having a structure of several layers. Ink is supplied to the head side from the outlet 36. Reference numeral 35 denotes an ink end detection plate. Due to the weight of this plate, the position of the ink decrease is lowered, and electrical contact is made at 38 via a detection lever 38 to detect the end of ink.
しかしながら、かかる方法では、以下にのべるような構
造的、価格的な幾つかの欠点を育していた。However, this method has several structural and cost disadvantages as described below.
′！Ｊ１に、何らかの衝撃によりインク袋が破損した場
合、流出したインクは、取出口や、検出器部分の貫通穴
を通して外部へ流れでる。インクによっては、アルカリ
性等、人体に有害なものもある為、単に周囲を汚すとい
う問題に留まらず、非常に重大な問題となる。′! If the ink bag is damaged by some kind of impact in J1, the leaked ink will flow out through the outlet and the through hole in the detector part. Some inks are alkaline and can be harmful to the human body, so this is not just a problem of staining the surrounding area, but a very serious problem.
第２に、 レバ一式でインクエンド検出を行ない、隔壁
を設けている為、供給できるインクの量に比較して、特
に高さ方向に大きなスペースを必要として〜）る。これ
は、プリンタ本体の設計上、支障になり、かつ価格上昇
ももたらす原因であった。Second, since ink end detection is performed using a set of levers and a partition wall is provided, a large space is required, especially in the height direction, compared to the amount of ink that can be supplied. This was a problem in the design of the printer body, and also caused an increase in price.
第３にインクエンド検出が、検出板の自重に頼っている
為、インク袋のつぶれ方が一定でない場合、十分に残量
があるのに検出してしまったり、逆にインクがなくなっ
ても、検出できない場合があった。Thirdly, ink end detection relies on the weight of the detection plate, so if the ink bag collapses unevenly, it may be detected even though there is enough remaining ink, or conversely, even if the ink runs out, There were cases where it could not be detected.
第４に、インク袋は、容器にしっかり固定させないと耐
衝撃性に問題があり、上部のインクエンド検出板もまた
、インク袋にしっかり接着する必要があった。インク袋
そのものには十分な剛性がない為、接廿力を安定化させ
るのは、技術的に難しかった。Fourth, the ink bag has a problem with impact resistance unless it is securely fixed to the container, and the upper ink end detection plate also needs to be firmly adhered to the ink bag. Since the ink bag itself does not have sufficient rigidity, it was technically difficult to stabilize the contact force.
第５に、以上のべた幾つかの理由−隔壁の存在とその接
着、インク袋の接着、スペースが広くなる等の問題はす
べて価格上昇につながっていた。Fifth, the several reasons mentioned above - the presence of partition walls and their adhesion, the adhesion of ink bags, the increased space, etc. all led to an increase in price.
本発明はかかる問題点を一気に解決するものであり、イ
ンク袋をフェルト状のインク吸収体により挟持し、容器
中に収容する。また、インク袋は、常に一定のバネ圧に
よってインクエンド検出板に押圧されている構造とする
。The present invention solves these problems at once, and the ink bag is sandwiched between felt-like ink absorbers and housed in a container. Further, the ink bag is always pressed against the ink end detection plate by a constant spring pressure.
つまり、本発明のインク供給容器は、インフジエラ（記
録装置にインクを供給するインク供給容器において、該
容器はインクを収納するインク袋と、 インクを回収す
るインク吸収体と、インク終了を検出するインクエンド
検出装置により構成され、前記インク吸収体は前記イン
ク袋を上下より挟持して成ることを特徴とする。In other words, the ink supply container of the present invention is an ink supply container that supplies ink to a recording device, and the container includes an ink bag for storing ink, an ink absorber for collecting ink, and an ink supply container for detecting the end of ink. The ink absorber includes an end detection device, and is characterized in that the ink absorber is configured to sandwich the ink bag from above and below.
なおインク袋は常時一定のバネ圧により、インクエンド
検出板を介して押圧されていてもよい。Note that the ink bag may be constantly pressed by a constant spring pressure via the ink end detection plate.
このようにインク袋をインク吸収体で挟持することによ
り、万一、袋からインク漏れがあっても吸収体で吸収す
ることができ、容器外への流出は発生しない、また、隔
壁がな（なることで構造が簡略化でき、信頼性も向上す
る。インク吸収体がインクを吸収する為、密封性も従来
技術はど要求されなくなる。By holding the ink bag between the ink absorbers in this way, even if ink leaks from the bag, it can be absorbed by the absorbers, and no leakage outside the container occurs.Also, there are no partition walls ( This simplifies the structure and improves reliability.Since the ink absorber absorbs ink, the conventional technology no longer requires sealing performance.
さらに、インク吸収体はフェルト状で弾性があり衝撃を
吸収する為、落下等によりインク袋へ衝撃が加わり、ダ
メージを受けるのを防止できる。Furthermore, since the ink absorber is felt-like and elastic and absorbs shock, it is possible to prevent the ink bag from being damaged by shocks caused by drops or the like.
さらに、インクエンド検出板がバネ圧でインク袋を押す
ことによって、インク袋つぶれ量検出の信頼性が上がり
、また、正確にエンド検出するととができる。Furthermore, since the ink end detection plate pushes the ink bag with spring pressure, the reliability of detecting the amount of ink bag collapse is increased, and the end can be detected accurately.
以下に具体的実施例を示す。 Specific examples are shown below.
第１図は本発明の一興体例で１１が容器外壁、１２がイ
ンク吸収体で、該吸収体に挾み込まれるかたちでインク
袋１３が収納されている。１５はインクエンド検出板で
、インク吸収体を上部から全面でバネ１６により押しつ
けている。FIG. 1 shows an example of the present invention, where 11 is the outer wall of the container, 12 is an ink absorber, and an ink bag 13 is housed in the absorber. Reference numeral 15 denotes an ink end detection plate, and the ink absorber is pressed against the entire surface from above by a spring 16.
第２図はインクが使用され、インクエンド検出が作動し
た状態を示す図で、インクエンド検出板１５の末端にあ
る端子が検出器１９に接触し電気的に検出するようにな
っている。検出器１９は、主としてマイクロスイッチタ
イプのものが、使用される場合が多い。この様な構造を
をすることで前述した問題点は総て解決することができ
た。FIG. 2 shows a state in which ink is used and ink end detection is activated, and the terminal at the end of the ink end detection plate 15 contacts the detector 19 for electrical detection. The detector 19 is often of the microswitch type. By having such a structure, all of the problems mentioned above could be solved.
すなわち、第１に何らかの原因でインク袋が破損し流出
しても、周囲を包んでいるインク吸収体により、直ちに
吸収されて外部への流出はない。That is, first, even if the ink bag is damaged for some reason and leaks out, the surrounding ink absorber absorbs the ink immediately and there is no leakage to the outside.
ｔＪ２に、インクエンド検出板がインク袋及びインク吸
収体を全面で押し、かつバネ荷重で強制的に均一に押し
ている為、インクエンド検出の信頼性は向上し、スペー
スメリットも出せる。At tJ2, the ink end detection plate pushes the ink bag and the ink absorber with its entire surface and is forced and evenly pressed by the spring load, so the reliability of ink end detection is improved and space benefits can be achieved.
第３に、インク袋はフェルト状インク吸収体に挾み込ま
れて保持されている為、耐衝撃性が著しく向上する。Thirdly, since the ink bag is held between the felt ink absorbers, the impact resistance is significantly improved.
第４に、バネ荷重で全体を押さえている為、接着等の問
題は一切発生しなくなり、低コスト化につながる。Fourth, since the entire structure is held down by a spring load, problems such as adhesion do not occur at all, leading to lower costs.
第５に、製造工程が簡略化され、かつ構造がシンプルに
なったことにより、コストダウンが促進される。Fifth, the manufacturing process is simplified and the structure is simplified, which promotes cost reduction.
この構造は、いうまでもなく図示した形聾のみがを効な
わけでなく、幾つかのバリエージ５ンとして、検出方法
の変更や、吸収体の配置の変更などを考えることができ
る。Needless to say, this structure is not only effective for the type of deafness shown in the figure, but several variations can be considered, such as changing the detection method and changing the arrangement of the absorber.
