Abstract

PURPOSE:To enable the subject product to be fabricated with a simple structure easily by providing a distance of 10-40mum to the opposed arrangement positions of a substrate having a thermal resistor and an orifice plate having a perforated orifice. CONSTITUTION:Plural pieces of resistor 2 which becomes hot by the application of a pulse current are arranged on a substrate at equal intervals. Then an orifice plate 3 is bonded air- and water-tight with its external edge on the substrate 1 so that an ink chamber 5 may be formd with a fixed distance from the substrate 1. An orifice 4 having a diameter of 20-100mum is perforated corresponding to each resistor 2 on the orifice plate 3. A single or plural pieces of orifice 4 should be provided corresponding to resistors 2 with no barrier between orifices 4. The distance between the substrate 1 and the orifice plate 3 is strictly limited to 10-40mum. Thus the unnecessary flying of ink droplets due to pressure leak into the adjoining orifice 4 is prevented. As a result, the subject product is provided with a simple structure, a fast continuous printing capability and a high recording characteristic free from unnecessary record generation by the interference of an adjacent resistor 2.

ンクジェット方式のヘッドに関するものである。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an inkjet print head, which is an inkjet head that ejects ink in the form of small droplets and attaches it to recording paper. .

チ化が容易である等の有利な点が多い。Conventionally, this inkjet recording method has two methods: a continuous method in which ink droplets are continuously generated and are controlled by an electric field, etc., and a continuous method in which ink droplets are ejected from an orifice only when recording is necessary. There is a demand method. On-demand methods include a method that generates droplets using the mechanical vibration of a piezo vibrating element and a method that generates droplets using heat from a heating element, but methods that use a heating element have a faster recording speed. It has many advantages, such as the ease of multi-head design, which is important for achieving high performance.

力室を形成する技術手段が提案されている。An inkjet recording means using this heating element is disclosed in Japanese Patent Laid-Open No. 54-59936 as a recording method and apparatus thereof. That is, when a pulse is applied as a recording signal to a heat generating resistor installed in an ink chamber, the ink is vaporized due to heat generation and a bubble is generated, and the pressure of the bubble causes the ink to be ejected from an orifice and adheres to the recording paper, etc. The system is designed to allow recording. However, in such recording means, a problem arises in that the pressure of bubbles formed in adjacent heads spreads to other orifices, causing ink to be ejected from the orifices corresponding to heating element elements to which no recording signals are input. In order to prevent this, there is a technology in which a barrier is provided between each orifice to form a pressure chamber, as in the print head shown in Japanese Utility Model Application Publication No. 59-174245 and Japanese Patent Application Publication No. 59-207261. Measures have been proposed.

ッドを提供することを目的とする。[Problems to be solved by the invention] With the conventional technical means of forming a pressure chamber by providing a barrier between each orifice, the shape of the head becomes very complicated, so when manufacturing the head, etching of the pressure chamber is necessary. Extremely sophisticated microfabrication technology is required for bonding to the substrate, etc. Therefore, it has the disadvantage of high manufacturing cost. The present invention has been made with attention to these points,
An object of the present invention is to provide an inkjet printing head that has a simple structure and is easy to manufacture.

The opposing arrangement distance between the plate and the orifice plate having the orifice formed therein is set to 10 to 40 μm.

ンクがインク滴７としてオリフィス４から吐出される。[Example] First, before explaining the present invention in detail, the basic structure and operation of the inkjet printing head of the present invention will be explained.As shown in FIG.
The orifice plate 3 is joined to form the ink chamber 5, but the shape of the orifice plate 3 restricts the gap between the heating resistor 2 and the orifice 4 bored at the corresponding position. . When a pulse current is applied to the resistor 2, the resistor 2 generates heat, which vaporizes the ink and forms a bubble 6 as shown in FIG. The pressure of the bubble 6 causes the ink in the ink chamber 5 to be ejected from the orifice 4 as ink droplets 7.

インク室５内にインクを流し込む必要がある。When the application of the pulse current is removed, the temperature of the resistor 2 decreases and the bubble 6 disappears as shown in FIG. In order to supply ink again onto the resistor 2 where the bubbles have disappeared, it is necessary to flow ink into the ink chamber 5 from the outside through the gap between the substrate 1 and the orifice plate 3.

すれば、ヘッドとして充分な機能を有することになる。In this case, experiments have shown that if the gap between the substrate 1 and the orifice plate 3 is less than lOt1m, the ink inflow speed is slow and it becomes difficult to make the ink fly continuously; When the diameter exceeds 40 μm, the pressure of the bubble spreads to the adjacent orifice, and as shown in FIG. 4, ink is ejected from the orifice 4 corresponding to the resistor 2 to which no pulse current is applied, resulting in unnecessary recording. It turned out that this was done. Therefore,
If the gap between the substrate 1 and the orifice plate 3 is 10 to 40 μm, it will have sufficient functionality as a head.

An orifice 4 with a diameter of 20 to 100 μm is bored. Therefore, when a pulse current is applied to the resistor 2, the ink is vaporized by the heat generated and bubbles are generated, and the pressure of the bubble causes the ink in the ink chamber 5 to fly out from the orifice 4 as small droplets to perform recording. . The ink consumed by this recording is transferred to an ink supply port 8 formed in the substrate 1.
The ink chamber 5 is replenished through the ink chamber 5.

This second embodiment differs from the first embodiment in that a large number of orifices 4 are provided corresponding to the heating resistors 2. The rest of the structure is exactly the same as the first embodiment shown in FIGS. 5(A) and 5(B).

In order to examine the effect on the printing chamber, etc., we varied the interval from 0 to 100 μm and the stability of recording when the interval of applied pulses was varied from 30 to 1 m5ec. The results of an experiment on the effect on adjacent orifices are shown. Table 1 shows the results of the first example, and Table 2 shows the results of the second example.

- Orifice that does not record at all, interference between ○... Orifice corresponding to adjacent dots'' As shown in Tables 1 and 2 above, pulses are applied continuously at pulse intervals of 30 to 1 m5ec, The stability of recording was evaluated in three levels: 0, where recording was performed continuously according to the applied pulse; △, where incomplete recording occurred in some areas; Δ, where ink did not fly If the distance between the orifice plate 3 and the substrate 1 is 10 μm or more, there is no problem with the stability of recording, but at 0 μm, the printing stability decreases as the pulse interval is shortened. This is because the ink supplied from between the orifice plate 3 and the substrate 1 becomes difficult to flow when the gap between the orifice plate 3 and the substrate 1 becomes narrow, and cannot keep up with the recording speed.

が見られ、特にパルス間隔の短い範囲で多く発生した。On the other hand, a pulse was applied to the head with no buffer applied to the adjacent orifice, and it was observed whether ink was ejected from the orifice corresponding to the resistor to which no pulse was applied. A case where the ink did not fly from the adjacent orifice was marked as 0, and a case where the ink did fly was marked as ×. As a result, interference with adjacent orifices of 50 μm or less was observed, and this occurred particularly frequently in the short pulse interval range.

ブルの圧力が横方向に広がり隣接するヘッドからのイン
クの飛翔が起るものと考えらる。This is thought to be due to the fact that as the distance between the substrate and the orifice plate increases, the pressure of the bubble spreads laterally, causing ink to fly from adjacent heads.

Strictly keep the distance from the orifice plate to 10~
It is necessary to regulate the thickness to 40 μm.

。[Effects of the Invention] As described above, according to the present invention, there is no need to provide barriers or partitions between each orifice, so the configuration is extremely simple, high-speed continuous printing is possible, and interference between adjacent resistors is avoided. It is possible to provide an inkjet printing head that has excellent recording characteristics that do not cause unnecessary recording.
