【発明の詳細な説明】
［産業上の利用分野コ
本発明はインクジェットプリンタの印字ヘッドの構造に
関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of a print head of an inkjet printer.
［従来の技術］
従来のインクジェットプリンタでは、液状インクが用紙
面において、内部に浸透した後、自然乾燥することを利
用した方式が生湯であり、一部には熱によって溶融し、
常温で再び硬化する性質を利用したものも見受けられた
。[Prior Art] In conventional inkjet printers, the method of using raw hot water is that liquid ink permeates inside the paper surface and then dries naturally.
There were also some products that took advantage of the property of curing again at room temperature.
［発明が解決しようとする課題］
しかしながら、前述の従来技術では、自然現象を利用す
る方式であるため、意図せざるときにインクが硬化して
しまい、結果、ノズルの目詰まりが発生しやすかった。[Problem to be solved by the invention] However, since the above-mentioned conventional technology utilizes a natural phenomenon, the ink hardens unintentionally, and as a result, nozzles are likely to become clogged. .

発明はこの様な問題点を解決するために、インクの硬化

る。In addition, since the curing of the ink cannot be directly controlled, stains may occur due to droplets. Therefore, in order to solve these problems, it is an object of the present invention to provide a means for directly controlling the curing of ink.
［課題を解決するための手段］
本発明では、紫外線を照射されると硬化する特性を有す

御しようとすることが特長である。[Means for Solving the Problems] In the present invention, a liquid ink having a property of curing when irradiated with ultraviolet rays is used, and an ultraviolet ray irradiation mechanism is provided near the ejection nozzle to directly ink the ink. The feature is that it attempts to control curing.

い。[Function] According to the present invention, the liquid ink is cured only when irradiated with ultraviolet rays.
For example, there is no fear that the ink will harden and cause clogging in the ejection nozzle or in the middle of the ink supply path. Moreover, since the ink that adheres to the paper surface is immediately irradiated with ultraviolet rays and cured, it not only prevents smudges and stains, but also continues to be exposed to natural ultraviolet rays, so even if some amount of ultraviolet rays are exposed, There is no inconvenience even if there is a shortage.

ズル１を通して、用紙面８に噴射する。FIG. 1 is a configuration diagram of a print head in an embodiment of the present invention. 1 is an injection nozzle, and 2 is an injection mechanism using a piezoelectric element such as a piezo. 3 is an ink supply path, and 4 is an ink chamber. 5 and 6 are ultraviolet irradiation mechanisms, which are attached to the left and right sides of the spray nozzle in addition to the bidirectional printing. Items 1 to 6 above are attached to a carriage stand 7, and have a structure in which they can be moved left and right by a carriage mechanism. The liquid ink stored in the ink chamber 4 passes through a supply path 6 and is supplied to the ejection mechanism 2. The ejection mechanism 2 is a small chamber made of a piezo element, and when a voltage is applied, it deforms and ejects the liquid ink inside through the ejection nozzle 1 onto the paper surface 8.

間となる。The ink that adheres to the paper surface remains in that position for a while due to surface tension, and some of it penetrates into the paper due to capillary action.After a short period of time, it is irradiated with ultraviolet light and the ink sticks to the paper surface. The ink cured. Figure 2 shows this situation in chronological order. That is, ejection from all nozzles is completed within the time from t to t2, and then from t2 to t3. The time from t3 to t4 is spent for the ink to penetrate into the inside of the paper, and the time from t3 to t4 is the time for the ink on the paper surface to harden by irradiation with ultraviolet rays.

ある。The carriage stand 7 is moved left and right by the carriage mechanism, and at that time, it is irradiated with ultraviolet rays by an ultraviolet ray irradiation mechanism located at the rear with respect to the traveling direction of the carriage. The UV irradiation mechanism has a certain degree of directionality, and while it is sufficient to cure the liquid ink in the area irradiated from the front, the irradiation takes place for quite a long time with a small amount of scattered light from the paper surface. The ink will not harden unless Therefore, the ink will not harden unintentionally near the ejection nozzle. Further, even in the ink chamber, the ink will not harden unless it is intentionally irradiated with ultraviolet rays, so there is no need to be so careful when handling it. The same applies to ink storage and replacement.

In addition to handling the printer, we also provide maintenance,
It is expected that ink replacement will become easier.
