本発明は、記録液を吐出する記録ヘツドと該記
録ヘツドに供給する為の記録液を貯蔵する記録液
の貯蔵部を一体化した記録ヘツドカートリツジに
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording head cartridge that integrates a recording head for discharging recording liquid and a recording liquid storage section for storing recording liquid to be supplied to the recording head.
従来、記録液を吐出する記録ヘツドを用いる記
録装置においては、記録に必要な記録液は、記録
ヘツドとは別個の場所に設けられた記録液貯蔵部
（タンク）より、可撓性パイプの如き供給管によ
り供給するものである。かかる記録装置において
は記録液の不足時には、供給管をタンクより取り
外した後、古いタンクを記録液が充分格納されて
いるタンクと交換することによつて記録液の補充
を行なうのが通常である。 Conventionally, in a recording device that uses a recording head that ejects recording liquid, the recording liquid necessary for recording is stored in a flexible pipe or the like from a recording liquid storage section (tank) provided in a location separate from the recording head. It is supplied through a supply pipe. In such a recording device, when there is a shortage of recording liquid, it is usual to replenish the recording liquid by removing the supply pipe from the tank and then replacing the old tank with a tank that contains enough recording liquid. .
ところで、前記記録ヘツドにおいて記録液を吐

記録液中に混入したゴミがノズル内に入ることに
より、或いは長時間記録を行なわないで放置して
記録液中に生じた沈澱がノズル内に入ることによ
り、ノズル中を流れる記録液の流量が減少し、記
録液の吐出効率や信号応答性を低下させる。更に
はノズルが目詰りを起したりして、吐出不能を招
来したりする。前述の様に、記録液の補充の為に
タンクを交換する場合には殊に記録液中に空気中
又は周囲に散在するゴミが混入する可能性が大と
なるので前述の如き事態が発生してしまう可能性
が大きくなるものである。 By the way, since the inner diameter of the nozzle having the ejection orifice for ejecting the recording liquid in the recording head is generally several tens of microns,
The flow rate of the recording liquid flowing through the nozzle may be reduced due to dust mixed in the recording liquid entering the nozzle, or due to sedimentation formed in the recording liquid entering the nozzle after being left without recording for a long time. This decreases recording liquid ejection efficiency and signal response. Furthermore, the nozzle may become clogged, resulting in inability to eject. As mentioned above, when replacing the tank to replenish the recording liquid, there is a high possibility that the recording liquid will be contaminated with dust that is in the air or scattered around, so the situation described above will not occur. This increases the possibility that this will happen.
又、長時間吐出オリフイスよりの記録液の吐出
を停止していると、記録液が乾燥して吐出オリフ
イス囲りに、付着して、再び記録を開始した場合
に吐出方向の安定性が得られないばかりか、吐出
不能を来たす場合もある。この場合には、新しい
記録ヘツドと交換する必要があるが、該交換時に
も、先に述べたタンクの交換時に起る様な不都合
が生ずる。 Also, if the ejection of recording liquid from the ejection orifice is stopped for a long time, the recording liquid will dry and adhere to the area around the ejection orifice, making it difficult to maintain stability in the ejection direction when recording is started again. In some cases, it may not be possible to eject the liquid. In this case, it is necessary to replace the recording head with a new one, but the same inconveniences that occur when replacing the tank as described above occur during this replacement as well.
又、前述の様に、タンクや記録ヘツドの交換の
際に、タンク内や記録ヘツドのノズル内、更には
記録液の流通路内に空気が混入する場合があり、
斯かる場合には吐出効率、液滴形成の安定性、応
答性或いは径路中の流通性等が低下してしまうも
のである。 Furthermore, as mentioned above, when replacing the tank or recording head, air may get mixed into the tank, the recording head nozzle, or even the recording liquid flow path.
In such a case, the ejection efficiency, stability of droplet formation, responsiveness, flowability in the path, etc. are reduced.

気泡の混入を生じさせ、吐出不良を招へいする。
また装置本体を持ちはこびするような場合にも上
記のような現象が生じる。 The amount of recording liquid used for recording is small, and if the stability of the recording liquid is taken into consideration, it is conceivable to fill the tank with the minimum required amount and form such a head and tank as one unit. However, if they are integrally formed in this way, the following problems will occur. In other words, cartridge-shaped recording heads can be used in mini printers such as hand-held calculators and typewriters; The recording head cartridge may be scanned at this time, and the vibration and impact at this time cause the recording liquid to ripple, causing air bubbles to enter the nozzle, leading to ejection failure.
The above-mentioned phenomenon also occurs when the user holds the main body of the device.
本発明は上述の如き欠点を除去した記録ヘツド

It extends to the bottom of the reservoir 3. At this time, the space between the supply pipe 5 and the partition wall 6 is hermetically sealed, and the tip of the nozzle 4 is slightly (distance) from the tip of the head storage section 2.
4d only) It is stored so that it recedes. By retracting the nozzle tip in this way, it is possible to prevent the nozzle from being damaged when the recording head is transported or when recording paper is attached or detached. The recording liquid storage section 3 is constructed by removing the head storage section 2 from the casing 1, and its bottom section 7 is configured so that even when the recording liquid becomes low, the recording liquid can be effectively supplied to the supply pipe 5. It is slanted so that it can be supplied. A film 8 having micropores is provided on the partition wall 6 between the recording liquid storage section 3 and the head storage section 2 to make the pressure inside the recording liquid storage section 3 equal to atmospheric pressure.

Even if the recording head cartridge is overturned, it has a function that prevents the recording liquid inside from flowing out for a short period of time.

Electrodes 10-1 and 10-2 are provided on the back surface of the housing 1, and these electrodes are terminals for applying a recording signal to the recording head from outside the recording head, and are connected to the piezo element 5 by a signal line (not shown). It is something that is connected.
Therefore, when such a recording head is mounted on a head carriage of a computer, typewriter, facsimile, word processor, or other recording device, the recording head can be used by connecting the electrodes to a connector provided on the head carriage. A drive signal can be applied to the inkjet head from the head carriage.

There is. The pores of the porous body are adjacent to each other and each pore has a penetrating portion to form a continuous liquid flow path. However, from a microscopic perspective, the recording liquid is confined in each hole, so there is no movement of the liquid in response to sudden vibration shocks.
Therefore, it is possible to substantially prevent the mixing of rippled air bubbles and the like.

The inside of the bag 11 is filled with recording liquid, and the connection portion with the supply pipe 5 is hermetically sealed. Therefore, even if the recording liquid gradually decreases due to being discharged to the outside, the volume of the bag 11 also decreases as the recording liquid decreases, so that no space is created. Therefore, even if a vibration shock is applied, the recording liquid does not bubble, and abnormalities in the ejection state of the recording head can be prevented. Incidentally, one of the features is that when the bag 11 is used, there is no particular need to use the film 8 shown in FIG. 1.
