Description
【発明の詳細な説明】 （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
インク供給容器に関し、特に、インクのニアエンド検知
機構を備えたインク供給容器に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink supply container for supplying ink to an inkjet recording apparatus, and more particularly, to an ink supply container equipped with an ink near end detection mechanism.
（従来技術） インクの供給が断たれるのを事前に予告して、インク
供給容器の交換を促すようにした装置についてはこれま
でに多くの提案がなされている。(Prior Art) Many proposals have been made so far for a device that gives advance notice of interruption of ink supply and prompts replacement of the ink supply container.
特開昭59−194855号公報に開示された装置もこの１つ

ンクの終端直前に検出領域内に入り込むよう位置させ
て、インク収納袋内のインクが枯渇するのを事前に予告
するようにしたものである。The device disclosed in Japanese Patent Laid-Open No. 59-194855 is also one of the devices. The ink is placed by locating a part of the sheet member placed on the ink storage bag so as to enter the detection area immediately before the end of the ink. This is to give advance notice that the ink in the storage bag will run out.
ところがこの種のインク収納袋では、インクの消費量

もたらす。However, in this kind of ink storage bag, the ink inside does not always decrease in proportion to the amount of ink consumed, and the sheet plate above it may not descend horizontally. Despite the fact that there is enough ink left in the box, it will indicate that it is in the near-end state and cause the ink storage bag to be replaced in vain, or even if the ink is completely exhausted This causes an inconvenience such that printing is not possible without displaying.

ある。(Means for Solving the Problems) That is, according to the present invention, as an ink supply container for achieving the above-mentioned problems, a detection member carrying an ink absorber for containing recovered ink is placed on an ink storage bag and The other end of the detection member is an ink near-end detection section with respect to the introduction section for guiding the recovered ink to the ink absorber, and this section is located above the detection means.
（実施例） そこで以下に本発明の実施例について説明する。(Example) Then, the Example of this invention is described below.
第１図は本発明の一実施例を示したものである。 FIG. 1 shows an embodiment of the present invention.

載されている。On the other hand, reference numeral 2 in the figure is a near-end detection plate that holds the ink absorber 6 that contains the recovered ink and that detects the near-end of the ink 3. The near-end detection plate 2 has the recovered ink on the upper surface. It is described on the ink storage bag 1 in a state of carrying the ink absorber 6 that stores the ink.

ではリミットスイッチ10の直上部に位置させている。A plate 8 to be detected is integrally provided on the lower end of the near-end detecting plate 2 on the opposite lower surface to the inlet 7 for collecting the ink provided on the upper side of one side of the cassette case 4. The case 4 is made to project below an opening 9 provided on the lower surface, and is located just above the limit switch 10 in this embodiment, that is, a detector arranged below the opening 9.

ようにして位置している。In the embodiment configured as described above, when the new cassette case 4 is loaded in the ink jet recording apparatus, sufficient ink is stored in the ink storage bag 1. As shown in FIG. 1A, the near-end detection plate 2 placed on the position 2 is positioned so that the plate 8 to be detected provided on the lower surface of the other side is separated from the limit switch 10.

させてゆく。In this state, while supplying ink to the print head (not shown), the required recording / writing is performed, and at the same time, the suction pump (not shown) is operated at the time of writing to record to suck the ink in the print head to clean the inside. When this is done, the volume of the ink storage bag 1 decreases in proportion to the amount of ink consumed, while the ink absorber 6 gradually increases its weight from one side by the recovered ink that has flowed in from the inlet 7. go.
このようにしてインクの消費がさらに進み、インクの
残量がある設定値以下になってくると、インク収納袋１

てゆくようになる。In this way, when the ink consumption further progresses and the remaining amount of ink falls below a set value, the ink storage bag 1
Is further reduced, while the ink collected from one side to the other side is gradually spread inside the ink absorber 6.
このため、インク収納袋１は、ニアエンド検知板２を

４の交換を促す。Therefore, the ink storage bag 1 receives the entire load of the ink absorber 6 acting via the near end detection plate 2,
As shown in FIG. 1 (b), the near-end detection plate 2 is horizontally contracted and the detection plate 8 projecting on the lower surface of the other side is brought into contact with the limit switch 10 so that the display lamp (not shown) is displayed. Is lit or a buzzer is sounded to notify the user of the near end of ink and prompt the replacement of the cassette case 4.

２そのものを被検出部材として兼用させることにより、
この種の機構をより簡素化させたものである。In FIG. 2, an opening 9 is provided on the opposite side of the ink introduction port 7 of the cassette case 4, while a part of the near-end detection plate 2 placed on the ink storage bag 1 is projected outside from the opening 9. In this embodiment, the near end detection plate 2 itself is also used as a member to be detected.
This type of mechanism is more simplified.

ことができる。(Effect) As described above, according to the present invention, the detection member carrying the ink absorber is placed on the ink storage bag to detect the near end of the ink. By using the weight of the recovered ink that increases in proportion to the above, it is possible to perform more reliable near-end detection by using a simple detection member, and use the detection member on the side opposite to the ink introduction part as the near-end detection part. As a result, the recovered ink, which increases with the consumption of the ink, is spread over the entire ink absorber, and the ink storage bag is uniformly pushed down, whereby the near-end state of the ink can be accurately detected.
