Abstract

PURPOSE:To prevent a jet port from being clogged, by disposing a perforated mesh film with a feeding mechanism in contact with the jet port, and jetting an ink through a hole of the mesh film. CONSTITUTION:An ink 2 is supplied from an ink-reserving part 1 into a groove 3 by a pressurizing mechanism. The ink 2 supplied into the groove 3 is heated by a heat generating resistor 5, whereby a bubble 7 is generated in the ink 2, and under the action of the bubble 7, a droplet 8 of the ink is allowed to pass through a jet port 4 and a hole 9 of a mesh film 11 and to fly to a recording medium 6, thereby forming an image. When the hole 9 of the mesh film 11 is clogged due to drying of the ink 2 or the like, a feeding mechanism 10 is rotated to feed the film 11 in the direction of the arrow so that a new hole 9 comes into contact with the jet port 4. Accordingly, the clogging problem can be easily solved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording device that forms an image on a recording medium by jetting ink droplets from an ink jetting port.

[Conventional technology]

FIG. 4 shows a recording apparatus equipped with a conventional inkjet nozzle, as disclosed in, for example, Japanese Patent Application Laid-Open No. 60-71260. In the figure, (11 is an ink storage part that supplies the ejected ink f27, (32 is this ink storage part +11
This is a groove that guides the ink (2) from the ink (2) to the ejection port 14). (6) is a heating resistor as an ink droplet ejecting means provided in a part of this groove (31). A plurality of inkjet nozzles having such a configuration are lined up, and the ink +21 ejected from each is covered. An image is formed on the recording medium (6).

Is this Isomizo's behavior? Figure 5 (4), (shown in B1. In Figure 5 (AI), ink (2) is 77
The entire 4ta+ is filled. By energizing the heating resistor (6), the ink (
A puzzle ( ) is generated during 21, and the pressure causes the jet nozzle (4
) from which a droplet (8) of ink is ejected.

[Problem that the invention seeks to solve]

Since the conventional inkjet nozzle (F) is configured as described above, the ejection port (41) for ejecting ink (2) may become clogged, and when clogging occurs, There was a problem in that the entire inkjet nozzle had to be replaced.

The present invention was made to solve the above problems, and an object of the present invention is to provide a recording device that prevents clogging of the jet nozzle.

[Means for solving problems]

The recording device according to the present invention has a porous mesh film equipped with a feeding mechanism in contact with an ejection port, and ink is ejected from the pores of the mesh film.

[Effect]

In this invention, the mesh film can be used by the feeding mechanism even if the holes that eject ink become clogged.

By feeding the mesh, new unclogged holes can be easily obtained, and the inkjet nozzle can be operated normally without replacing the entire inkjet nozzle.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 4
In Figure 1, +11 is an ink reservoir that supplies ink (21) to the pressurizing mechanism, and (3) is a groove connected to this ink reservoir and having sufficient space to guide and hold the ink. , (41 is the ink+21 ejection port provided on one side of this groove (31). (II) I/j is a porous mesh film in contact with the surface of this ejection port (4), (9 ) is the hole on the mesh film (II). (IO) is a feeding mechanism provided at both ends of this mesh film (1) to feed the mesh film (II) in the direction of the arrow shown in the figure. (5) is the above A +
31 is a heating resistor provided on the opposite side of the spout (4). One of the holes (9) of the mesh film (11) is in contact with the spout +41.

In the recording apparatus configured as described above, ink (2
1 is supplied from the ink storage section +11 to the groove (31) by the pressurizing mechanism.The ink (2) supplied to this groove (31) is heated by the heating resistor (6), and the ink (2) A puzzle (7) is generated, and this puzzle (7) causes the ink droplet (8) to pass through the jet nozzle (4) and the mesh film (1 hole (9)) toward the recording medium (6). This state is shown in Figure 2, where the left side is a sectional view in the front direction and (B) is a lateral sectional view.

If the holes (9) of the mesh film (11) become clogged due to drying of the ink (2), etc., the feed mechanism (10)
Rotate and feed the mesh film (flit) in the direction of the arrow in Figure 2 so that the new hole (9) comes into contact with the spout (4).By doing this, clogging can be easily prevented. It can be resolved.

In addition, in the above embodiment, the number of holes (9) in the mesh film (11) that comes into contact with the jet nozzle (41) is one;
A plurality of these holes (9) may be in contact with one jet port (41) at the same time.

In addition, in the above embodiment, the mesh film (river feeding mechanism +
Although the case where the mesh film (II) is wound up with IO+ and a new mesh film is taken out and used is shown, the mesh film (II) can be configured to be endless and used in the same way. The implementation eAJ is shown in the cross-sectional view of FIG. In this diagram (!
1) is an endless mesh film, 101 is its feeding mechanism, and θ''4 is a solvent for dissolving the dried ink contained in the container.Others are the same as shown in FIG.

The holes (9) of the mesh film (+1) with M holes are fed by the feeding mechanism (10) in the direction of the arrow shown in the figure, and the lower half of the mesh film (11) is soaked in the solvent (12) K.
Since the ink (21) clogged in the holes (9) is cleaned with the solvent (12), the clogging can be eliminated and it becomes possible to use a plurality of mesh films (12) continuously.

As described above, this embodiment not only provides the same effects as the above embodiment, but also has the advantage that there is no need to replace the mesh film.

In addition, although the above two embodiments are based on a method in which ink is ejected by generating bubbles due to heating, a recording device that does not use bubbles and ejects all of the ink may also be equipped with the above-described feeding mechanism as an ejection port. If the holes of the mesh film are used, clogging of the holes can be easily solved.

Furthermore, although the mesh film is shown as having one hole per heating resistor, a porous mesh having multiple holes corresponding to one heating element may be used in order to eliminate the need for alignment.

〔Effect of the invention〕

As described above, according to the present invention, since a porous mesh film having a feeding mechanism is provided in contact with the ink ejection port of the recording device, if clogging occurs due to drying of ink, etc. This problem can be easily resolved by moving the mesh film.
