本発明はノズル内の液体をオリフィスから吐出させて紙
などの記録媒体に記録を行う液体噴射記録ヘッド（イン

止期間に液体の組成を変化させない液体噴射記録ヘッド
に関する。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a liquid jet recording head (including an inkjet recording head) that discharges liquid in a nozzle from an orifice to record on a recording medium such as paper, and in particular to a recording medium such as an inkjet recording head. The present invention relates to a liquid jet recording head that does not change the composition of liquid during a rest period when no storage is performed.

おいては、記録液が吐出される液流路先端に設けられた
オリフィスは、ヘッドの駆動の有無にかかわらず絶えず
ヘッド外部の外気に向けて開放されていることが多い。The recording liquid used when recording with an inkjet recording head generally consists of a recording agent such as a pigment or dye, and
It is formed mainly from water or a solvent component consisting of water and a water-soluble organic solvent or a non-aqueous solvent for dissolving or dispersing it. In an inkjet recording head, an orifice provided at the tip of a liquid flow path through which recording liquid is ejected is often constantly open to the outside air of the head, regardless of whether or not the head is driven.

画像の初期印字部等に欠陥を生じるという問題があった
。Therefore, if recording is not performed for a long time, some of the solvent will evaporate from the orifice into the outside air.
When the recording agent component and the solvent component that is difficult to volatilize remain in the recording liquid, the composition of the recording liquid staying in this area changes and the viscosity increases, resulting in an increase in viscous resistance in the liquid flow path area. Therefore, even though the ejection signal is applied, immediately after restarting recording after the printing material has stopped,
There has been a problem in that droplets are not ejected and droplet ejection failures tend to occur, resulting in defects in the initial printed portion of the recorded image.

33, JP-A-55-121074, JP-A-59-12
3672, JP-A No. 61-100461, etc., by using a type of head in which a sub-channel is connected to the liquid channel and circulating the recording liquid, an increase in viscosity in the liquid channel can be suppressed. Can be done. However, the head configured as described above has a problem in that the ejection energy escapes to the sub-channel and the droplets are not ejected at a sufficient speed. In order to prevent the discharge energy from escaping into the sub-channel, the communication port between the sub-channel and the liquid channel should be separated from the discharge energy generating means.
It may be placed at a more distant position. However, if the communication port is too far away from the ejection energy generating means, the recording liquid in the vicinity of the ejection orifice in the liquid flow path cannot be circulated, making it difficult to suppress an increase in the viscosity of the recording liquid.

It is an object of the present invention to provide a high-performance liquid jet recording device that does not cause any problems.

This is achieved by a liquid jet recording device that communicates with the communication port and is characterized in that a wall having a notch is provided in the liquid flow path so as to surround the communication port.

記録ヘッドにおいては該記録ヘッド中全体の記録液の水
分比率はほぼ一様に保たれ、吐出圧発生部とオリフィス
間のみの局所的な水分比率の低下を防ぐことができる。During recording, the ejection pressure generating section applies ejection pressure to the recording liquid in the liquid flow path to eject the recording liquid and perform continuous recording, similar to recording using a conventional inkjet recording head. . When this recording is stopped, the operation of the pump 6 is started and the recording liquid is supplied from the recording liquid storage section 7 to the pump 6 to the recording liquid passage 5 to the liquid flow path 1 to the liquid chamber 3 to the supply pipe 4 to the recording liquid storage section 7. cycle in this order. As mentioned above, the recording liquid flows through orifice 2.
If the recording liquid remains stationary in the liquid flow path because it is in contact with the atmosphere at
The increase in the viscosity of the recording liquid causes the initial ejection failure problem. However, in a recording head that circulates the recording liquid as in the present invention, the moisture ratio of the recording liquid throughout the recording head is kept almost uniform, and the moisture ratio decreases locally only between the ejection pressure generating part and the orifice. can be prevented.

れしやすくなるからである。At this time, since there is a wall surrounding the communication port, almost no energy is blown into the recording liquid path, which is a sub-flow path, during ejection, making it possible to perform good printing. Furthermore, since the amount of recording liquid in the entire recording head, including the liquid chamber and recording liquid storage section, is very large compared to the liquid flow path, the decrease in the moisture ratio of the recording liquid is negligible even after the print is stopped for a long time. be. The reason why the recording liquid is circulated in the above-mentioned direction is because if the recording liquid is circulated in the opposite direction, the pressure applied to the recording liquid in the direction of the orifice will increase, causing the meniscus of the recording liquid at the orifice to break and cause liquid leakage. It is from.
以下に本発明の液体噴射記録ヘッドについて、具体的実

るが、その向きは液流路長手方向と垂直になっている。FIG. 2(a) is a cross-sectional view of the head, and FIG. 2(b) is a cross-sectional view of the head.
2 is a diagram in which two liquid flow paths are extracted from an exploded schematic enlarged view of the head tip viewed from an angle. In the figure, 5b is a recording liquid passage leading to the pump, 8 is a heating resistor which is a discharge pressure generating part, 11 is a top plate, 12 is a substrate, 13a is a recording liquid supply path, +3b is a container for the recording liquid passage, 14 (second Figure (b)) is a partition that separates each liquid flow path, 15 is a wall surrounding the communication port 5a,
It has a notch 16. The notch is located on the rear side of the wall, and its orientation is perpendicular to the longitudinal direction of the liquid flow path.
これは、もし切欠きの向きが液流路方向に向いていると
吐出エネルギーが連絡口を通し記録液供給路に飛げてし
まうからである。また切欠きが壁の後方側に位置してい
るのは、もし前方側にあると循環している液体がメニス
カスを破りオリフィスから外部に漏れるからである。This is because if the notch is oriented in the direction of the liquid flow path, the ejection energy will pass through the communication port and into the recording liquid supply path. The notch is located at the rear of the wall because if it were at the front, the circulating liquid would break the meniscus and leak out through the orifice.
壁１５は、図かられかるように液流路長手方向に対し３
０°程度の傾斜をもっていてオリフィス面積をしぼる役
割もある。これはオリフィス１５が壁の役割りを果たす
とともに良好な印字を得るのに充分な吐出速度を得る目
的も果たしている。As can be seen from the figure, the wall 15 has a width of 3 in the longitudinal direction of the liquid flow path.
It has an inclination of about 0° and also has the role of narrowing down the orifice area. This allows the orifice 15 to act as a wall and also to obtain a sufficient ejection speed to obtain good printing.

As for the formation method, first, a surface resin is laminated onto a substrate. Next, a mask is attached so as to block light except for the partition wall 14 and the wall 15 and exposed, followed by solvent development to form a channel system. This is further laminated with the resin, and only the communication port 5a is masked and exposed, followed by solvent development to form the top plate 11. A head is created by gluing a glass container on top of this.

／ｓｅＣ程度が好ましい。In this recording head, the recording liquid sent from the pump passes through the recording liquid passage and flows into the liquid passage from the recording liquid passage communication port 5a, but since there is a notch 16 on the rear side of the wall 15, The liquid changes direction to the rear of the nozzle, passes through the liquid chamber and the supply pipe, and returns to the recording liquid storage section. Therefore, the meniscus at the orifice is broken. On the other hand, during printing, the flow of recording liquid goes from the communication port to the orifice in the opposite direction to that described above, but as described above, the wall 15 surrounding the communication port acts as a fluid diode, and the discharge pressure is controlled by the recording liquid path. I almost never run away. Note that if the speed of the recording liquid circulation is too fast, the meniscus in the orifice will break, and if it is too slow, the effect of the recording liquid circulation will not be obtained and the viscosity of the recording liquid near the orifice will increase. For example, in the case of a head having the structure of the following example, the liquid circulation speed is 1 to 2 fIlffl.
/seC is preferable.
