【実施例】 【Example】

実施例1 図1は、実施例1の記録ヘッドの断面図である。 Example 1 Figure 1 is a cross-sectional view of a recording head of Example 1. 記録ヘッド:11は、プレスや成型加工や電鋳等によりつくられた母材:42と、ノズル:2のあるノズルプレート: Recording head: 11, preform made by pressing or molding or electroforming, etc.: 42, nozzle: 2 of a certain nozzle plate:

圧電素子:4、とは、接着等の結合手段により、一体化される。 Piezoelectric elements: 4, and by binding means such as adhesion, are integrated. 実施例1では、導電性の接着剤で結合されている。 In Example 1, they are joined by a conductive adhesive. 圧電素子:4の形状は図1で左側となる正面側から見ればドーナツ状をしており、一方の電極はノズルプレートに導電性接着剤で接着され取り出され、もう一方の電極はリード線により外部に取り出される。 Piezoelectric elements: 4 shape has a donut shape when viewed from the front side to the left side in FIG. 1, one electrode is removed is bonded with a conductive adhesive to the nozzle plate, the other electrode by a lead wire It is taken out to the outside. ノズルプレート:7は、プレスや成型加工や電鋳等により、高精度に加工されたノズル:2を有している。 The nozzle plate 7 is, by pressing or molding or electroforming, etc., processed nozzle with high accuracy: has two. ノズルの口径は、50μmであり、加工の公差は、2μm以下に収められている。 Diameter of the nozzle is 50 [mu] m, the tolerance of processing are housed in 2μm or less.

【0021】図1では、1個のノズルと1個の圧電素子の記録ヘッドを示しているが、これらは、それぞれ複数個あってもよい。 [0021] FIG. 1 shows one nozzle and the recording head of one of the piezoelectric elements, it may be in plural, respectively. ここで、圧電素子:4にパルス状の電気信号を与えると、圧電室:1内の圧力が高まり、インク液滴:6がノズル:2から噴射する。 Here, the piezoelectric element: Given a pulsed electrical signal to 4, the piezoelectric chamber: increased pressure in 1, the ink droplet: 6 nozzles: injected from 2. 母材:42は、 The base material: 42,
インク供給路:3も形成し、噴射した量のインクはインク供給路:3の後部から圧電室:1へと供給される。 Ink supply channel: 3 also forms, ink ejection amounts of the ink supply channel: piezoelectric chamber from the rear of the 3: is supplied to the 1. 従来の記録ヘッドとの構成の違いは、高精度に加工されたノズルプレートが振動する構造となっている点である。 The difference of the configuration of the conventional recording head is that the nozzle plate which is processed with high accuracy and has a structure that vibrates.
図1で、記録ヘッドの圧電室:1を形成する母材:42 In Figure 1, a piezoelectric chamber of the recording head: base material to form a 1:42
の形状は、概略、ノズル:2のノズル口を焦点としたパラボラ曲線とするのが良い。 The shape of the outline, the nozzle: amount may be parabolic curve the second nozzle opening and the focus. これは、ノズルプレート: This is, nozzle plate:
7が振動して圧力室:1内に圧力を発生させた時、母材:42側で反射した圧力波が、ノズルに向かって集中し進行するようにさせるためである。 7 vibration to the pressure chamber: when caused the pressure in one, matrix: pressure wave reflected by the 42 side, in order to to proceed concentrated toward the nozzle. この構造の記録ヘッドは、構造が簡単であり、また、生産コストが安いため、特に、ノズル数の多い記録ヘッドに対して効果的である。 Recording head of this structure, the structure is simple, and since the low production costs, in particular, is effective against the nozzle having a large number of recording heads.

【0022】実施例2 実施例1では、ノズルプレートと圧電素子とが別部材である例を示したが、図2に示すように、ノズルプレートが圧電素子と同一部材であっても良い。 [0022] In Example 1, but the nozzle plate and the piezoelectric element is an example, another member, as shown in FIG. 2, the nozzle plate may be the same member and the piezoelectric element. この場合、構造がより簡単になるメリットがある。 In this case, there is a merit that the structure is simpler. 図2は、2層構造の圧電素子:8がノズルプレートと同一部材である例を示す。 Figure 2 is a piezoelectric element having a two-layer structure: 8 shows an example of the same member and the nozzle plate. 2層の圧電素子は中間層の埋め込み電極に対し、両側が同一方向に分極処理されている。 The piezoelectric element of the two layers relative to the buried electrode of the intermediate layer, both sides are polarized in the same direction. このため、両端の電極に電圧を印加させると、バイモルフの動きをして圧電素子が振動する。 Therefore, when applying a voltage to the electrodes at both ends, the piezoelectric element vibrates with the movement of the bimorph. 圧電素子の形や電極の構造はこの限りではなく、圧電素子とノズルを形成する部材とが同一部材である点がポイントである。 Structure shapes and electrodes of the piezoelectric element is not limited to this, point the member forming the piezoelectric element and the nozzle is the same member is a point.

【0023】実施例3 さらに、ノズルプレートがフィルム状の圧電素子であっても良い。 [0023] Example 3 In addition, the nozzle plate may be a film-shaped piezoelectric elements. 図3は通称PVDFと呼ばれる圧電性のあるフィルムを使用した例を示す。 Figure 3 shows an example of using a film of piezoelectric called aka PVDF. 以前から、例えば、特公昭60−34469のように、フィルムの収縮力が圧力室に間接的に作用するものは知られているが、直接的に、しかも、ノズルを形成する部材と圧電体であるフィルムとが同一である構造の記録ヘッドはなかった。 Previously, for example, as JP 60-34469, although it is known that shrinkage force of the film to act indirectly on the pressure chamber, directly, moreover, a member and the piezoelectric body forming the nozzle and there the film was not a recording head of the structure is the same. 図3 Figure 3
において、圧電フィルムの圧力室側には、薄く、インクに侵食されにくく、圧電フィルムに電圧を印加しても収縮しにくい部材がコートされている。 In, the pressure chamber side of the piezoelectric film is thinner, less likely to be eroded in the ink, the shrinkage hardly member even if a voltage is applied is coated on the piezoelectric film. このため、圧電フィルムに電圧を印加すると、圧電フィルムの収縮力でノズルを形成しているフィルムが振動する。 Therefore, when a voltage is applied to the piezoelectric film, the film forming nozzle in contractile force of the piezoelectric film vibrates.

【0024】フィルムの振動は、圧力室内の圧力を高めるとともに、圧力室内に圧力波を発生させる。 The vibration of the film, to increase the pressure in the pressure chamber to generate a pressure wave in the pressure chamber. 圧力波は、圧力室後部の曲面で反射してノズル方向に向い、ノズル付近で圧力波が集中して、インク液滴が噴射する。 The pressure wave is directed to the nozzle direction is reflected in the pressure chamber rear curved, concentrated pressure wave in the vicinity of the nozzle, ink droplets are injected.
ノズルの穴の加工精度は、厚さが約50μmのフィルムをプレス加工や、レーザー光線の照射で加工して、直径50μm±2μmの円形となり、十分な加工精度となっている。 Machining accuracy of the hole in the nozzle pressing or a film of about 50 [mu] m thick, processed by irradiation of the laser beam becomes a circle having a diameter of 50 [mu] m ± 2 [mu] m, and has a sufficient processing accuracy.

【0025】実施例4 図4は、実施例4のインクジェット記録ヘッドの断面を示す。 [0025] Example 4 FIG. 4 shows a cross section of the ink jet recording head of Example 4. 記録ヘッドの母材は、電気的に、母材1と母材2 Base material of the recording head, electrically, the base material 1 and the base material 2
