本発明はインクジェット記録装置の構造に関し、特に、
インク容器と記録ヘッドとの間を結ぶインク供給管の改
良構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to the structure of an inkjet recording device, and in particular,
The present invention relates to an improved structure of an ink supply pipe connecting an ink container and a recording head.
インクジェット記録装置は、インク容器内のインクを記
録ヘッドへ導き、該記録ヘッドに設けた複数のノズルを
印字データ信号に基いて駆動することにより用紙に向っ
てインクを噴出して記録していくよう構成され、プリン
タやファクシミリに採用されている。An inkjet recording device guides ink in an ink container to a recording head, and drives multiple nozzles provided in the recording head based on print data signals to eject ink toward paper for recording. It is used in printers and facsimile machines.
シリアル記録装置では、記録ヘッドは用紙に沿って移動
するキャリジ上に搭載され、インク容器は該キャリジ（
可動側）または装置本体（固定側）に装着される。また
、カラー印字の場合は、複数組（例えば黒、赤、青、黄
の４組）の記録ヘッドおよびインク容器が使用される。In a serial recording device, the recording head is mounted on a carriage that moves along the paper, and the ink container is mounted on the carriage (
(movable side) or the device body (fixed side). Furthermore, in the case of color printing, multiple sets (for example, four sets of black, red, blue, and yellow) of recording heads and ink containers are used.
ところで、この種のインクジェット記録装置における記
録ヘッドへのインク供給管としては、インク容器と記録
ヘッド、とを直接結ぶチューブ（ビニールチューブなど
）、あるいは記録ヘッド支持部材に設けたコネクタを介
して記録ヘッド側およびインク容器側のインク供給管を
接続する構造が考えられ、前者は皐扱い性がわるく記録
ヘッド交換時の再接続に手間を要するという難点がある
。By the way, the ink supply tube to the recording head in this type of inkjet recording apparatus is a tube (such as a vinyl tube) that directly connects the ink container and the recording head, or a tube that connects the recording head through a connector provided on the recording head support member. A structure in which the ink supply tubes on the side and the ink container side are connected is considered, but the former has the disadvantage that it is difficult to handle and requires time and effort to reconnect when replacing the recording head.
一方、後者の中間コネクタを使用するものは、取扱い性
にすぐれインク供給管の脱着が容易であるという利用が
あるが、従来の中間コネクタは金属製のバイブを記録ヘ

供給管との間に位置ずれに対する吸収能がなく、記録ヘ
ッド装着時にコネクタおよびインク供給管に無理な力が
作用し、耐久性が低下したりインク洩れが生じやすいと
いう問題がある。On the other hand, the latter type of intermediate connector is used because it is easy to handle and the ink supply tube can be easily attached and detached, but the conventional intermediate connector fixes the metal vibrator directly to the recording head support member. Therefore, when positioning and fixing the recording head, there is no ability to absorb misalignment between the connector and the ink supply tube on the recording head side, and when the recording head is installed, excessive force is applied to the connector and ink supply tube, resulting in poor durability. There are problems in that the properties are reduced and ink leaks easily.
本発明の目的は、このような従来技術の問題を解決し、
記録ヘッド交換時のインク供給管の脱着が容易であり、
接続時においても無理な力が作用せず耐久性および信頼
性にすぐれたインク供給管およびその取付は構造を提供
することでおる。The purpose of the present invention is to solve the problems of the prior art,
Easy to attach and detach the ink supply tube when replacing the recording head.
The ink supply tube and its mounting structure provide excellent durability and reliability without applying excessive force even when connected.
不発明は、キャリジヒにヘッド取付は台を固定するとと

達成するものである。The non-invention is that the head mounting unit fixes a stand to the carriage, and the head unit fixes the recording head to the stand, and further,
The head is mounted by attaching a hollow pin to the stand via a rubber-like elastic body, and connecting ink supply pipes on the recording head side and the ink container side to both ends of the hollow pin, thereby achieving the above object. .

無によりインク供給を検知するものである。In FIG. 4, the head is mounted by fitting a hollow pin 15 into a stepped hole 14 formed in the base 6 via a rubber-like elastic body 16. In the illustrated example, retaining rings 17, 17 are engaged with circumferential grooves formed at two locations on the hollow pin 15, and these retaining rings clamp the rubber-like elastic body 16, 16, and one (h side) ) By engaging the rubber-like elastic body 16 with the stepped portion of the hole 14, the hollow pin 15 is securely attached to the head mounting table 6 so that it can be elastically displaced. In the illustrated example, an electrode plate 18 for detecting the presence or absence of ink supply is held between the lower retaining ring 17 and the rubber-like elastic body 16. This electrode plate 18 detects the ink supply based on the presence or absence of conductivity of the ink supply pipe portion by utilizing the conductivity of the ink.
中空ピン１５は通常金属パイプで作られ、その下端には
