【発明の詳細な説明】
本発明は、インクジェット記録装置に用いられるインク
供給装置に関し、特に、カートリッジタイプのインク供
給装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ink supply device used in an inkjet recording apparatus, and particularly to a cartridge type ink supply device.
従来のインク供給装置においては、インク受渡し装置に
細い管状針を設け、この針でインク貯蔵部のゴムパツキ
ンを突きさすようにしていた。In a conventional ink supply device, an ink delivery device is provided with a thin tubular needle, and the needle is used to pierce a rubber gasket in an ink reservoir.
このため、パツキンと針との位置関係を正確なものにし
なければならず、又突きさした部分からインク洩れの心
配があった。For this reason, the positional relationship between the seal and the needle must be accurate, and there is also the risk of ink leaking from the pierced portion.
更に、針を複数本設けた場合、インク貯蔵部を受渡し装
置にセットする際は、押し込むだけで回転はできず、イ
ンク貯蔵部のセット動作、形状等制約が多く繁雑であっ
た。Furthermore, when a plurality of needles are provided, when setting the ink storage section in the delivery device, the ink storage section cannot be rotated by simply pushing it in, and there are many restrictions on the setting operation of the ink storage section, the shape, etc., and it is complicated.
本発明は、以上のような従来のインク供給装置の欠点を
解消し、容易にインク貯蔵部を着脱できインク洩れ等が
生じない様継手部（受渡し部）の信頼性を陶土させ、構
造簡単なインク供給装置を提供しようとするもので、以
下図面とともに本発明の詳細な説明する。The present invention solves the above-mentioned drawbacks of the conventional ink supply device, improves the reliability of the joint part (delivery part) so that the ink storage part can be easily attached and detached, and prevents ink leakage, and has a simple structure. The present invention is intended to provide an ink supply device, and the present invention will be described in detail below with reference to the drawings.

１はスリットである。FIG. 3 is a diagram showing how the double pipe connecting joint 7 and the ink cartridge are connected, and 10 is a double pipe for drawing out ink from the ink cartridge and introducing air;
1 is a slit.
第４図は、インクカートリッジ１を、二重管連結継手７
に装着した図で１２は気泡である。FIG. 4 shows the ink cartridge 1 connected to the double pipe connection joint 7.
In the figure attached to the camera, 12 is a bubble.
第２図にも示した様に、インクカートリッジは、中空部
分を有するゴム栓９（こよってインクが封入されており
、その前の位置にＯリング８を配置して二重管１０の外
径と対応するようＧこなっている。As shown in FIG. 2, the ink cartridge has a rubber stopper 9 having a hollow part (thus, ink is sealed in it), an O-ring 8 is placed in front of the rubber stopper 9, and the outer diameter of the double tube 10 is G is adjusted to correspond to this.
第４図において、カートリッジ１を押し込んで装着する
と、ゴム栓９は二重管端面で押し込まれて栓があけられ
る。In FIG. 4, when the cartridge 1 is pushed in and installed, the rubber stopper 9 is pushed in with the end face of the double tube and the stopper is opened.
この時、ゴム栓９は、中空のため、インク液面部に浮い
てしまい、出入口部で、インクの導出を妨げるようなこ
とはない。At this time, since the rubber stopper 9 is hollow, it floats on the ink liquid level and does not obstruct the ink from being drawn out at the inlet/outlet.
空気は、空気取入口４、二重管を通して入り、インク゛
は、二重管の端部開口とスリット１１から導出される。Air enters through the air intake 4, the double tube, and ink is led out through the end opening of the double tube and the slit 11.
第５図は、二重管連結継手７の、空気取入部とインク供
