本発明はインクジェット記録装置の構造に関し、具体的
には、インク吐出口の目づまり防止やインクの吐出状態
確認のためインク吐出口からインクを噴射する場合のた
めに設けられるインク受容手段の構造に係る。[Detailed Description of the Invention] [Technical Field] The present invention relates to the structure of an inkjet recording device, and specifically relates to the structure of an inkjet recording device, and specifically, when ink is ejected from the inkjet orifice to prevent clogging of the inkjet orifice or to check the ink ejection status. This relates to the structure of the ink receiving means provided for.
インクジェット記録装置は印字ヘッド（インク噴射ヘッ
ド）に設けた複数（例えば２４個）のインク吐出口から
印字データに応じてインクを吐出し、インク液滴を用紙
に付着させて記録を行うものである。An inkjet recording device performs recording by ejecting ink according to print data from a plurality (for example, 24) of ink ejection ports provided in a print head (ink ejection head), and depositing ink droplets on paper. .
第１図はインクジェット記録装置の要部構成を示し、装
置本体ｌ側（通常紙送りローラ）にセントされた用紙２
に沿って印字へソド３を矢印方向に往復動させながら上
記記録が行われる。Figure 1 shows the configuration of the main parts of an inkjet recording device, in which a sheet of paper 2 is placed on the l side of the device main body (normal paper feed roller).
The above recording is performed while reciprocating the print head 3 in the direction of the arrow.
ここで、前記インク吐出口は例えば直径が６０μｍ程度
と小さいので、空気中の塵埃やインク溶剤の蒸発などに
よる目づまりが問題になる。この目づまりは装置を長時
間使用せずに放置していた場合などに生じやすい。Here, since the diameter of the ink ejection port is small, for example, about 60 μm, clogging due to dust in the air, evaporation of ink solvent, etc. becomes a problem. This clogging is likely to occur when the device is left unused for a long period of time.
その対策として、電源を投入して記録を始める際印字へ
ラド３がホームポジションにあるとき、インク吐出口の
清掃あるいは吐出のＲＦ２．などのためインクをテスト
噴射することが行われる。As a countermeasure for this, when the printing head 3 is at the home position when the power is turned on and recording is started, cleaning the ink ejection opening or RF2. For example, ink is test-jetted.
このため、ホームポジションすなわち用紙２から外れた

できるようになっている。FIG. 2 shows a conventional ink receiving means 4, in which an ink receiver positioned at a predetermined position opposite the print head 3 is constituted by a member 5. In this ink receiver, the member 5 is made of an ink absorber such as a porous material such as sponge or a fibrous material such as felt, and the back surface (rear surface) of this ink absorber is usually provided with rigidity so that it can be handled easily when attached and detached. Thin Mylar film etc. to make it easier! Fi6 is fixed with adhesive. This ink absorber 5 is removably held in a storage section 7 of one example of the apparatus main body, so that an operator can replace it as appropriate when the absorption capacity of the ink absorber decreases or disappears.

インクのテスト噴射を繰返し、印字ヘッドに設けたイン
ク容器内のインクがなくなり該印字ヘッドを交換すると
きに同時にインク吸収体を交換するものであった。By the way, as shown in FIG. 2, the conventional ink receiving means 4 has a plate-shaped ink absorber 5 facing the print head 3. In order to prevent this (which tends to occur when the ink droplets become difficult to eject due to high levels of ink droplets) and to confirm ejection, test ejection of ink is repeated until the ink in the ink container installed in the print head runs out and the print head is removed. When replacing the ink absorber, the ink absorber was also replaced at the same time.

収能力が早期に失われ、吐出されたインクが吸収されず
に装置内に洩出し、装置内部や用紙２を汚しやすいとい
う問題があった。However, in such conventional jetting ink receiving means, one sheet of the absorber 5 is used, so when test jetting is performed when the print head 3 is positioned at the home position, the same sheet of the absorber 5 is always used. Sometimes ink is ejected at a certain point, and ink droplets adhere only to that point and get dirty quickly.When the ink dries and hardens, the ink absorption ability in that point is quickly lost, and the ejected ink There is a problem in that the liquid is not absorbed and leaks into the device, easily staining the inside of the device and the paper 2.
このため１．インクのテスト噴射の頻度によっては、イ
ンク吸収体５を早期に交換する必要がある。For this reason, 1. Depending on the frequency of test jetting of ink, it is necessary to replace the ink absorber 5 early.
しかし、従来構造では、前述のごとく、印字ヘッド３の

Since both the ink absorber 5 and the ink absorber 5 are to be replaced at the same time, only the ink absorber 5 cannot be replaced quickly.
また、インク吸収体５を複数枚用意したとしても、装置

。Furthermore, even if multiple ink absorbers 5 are prepared, only one ink absorber can be attached to the device, and the remaining ink absorbers must be stored separately, so they may be lost or forgotten to be replaced. There was a problem that there was a large possibility that
