Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention scans a recording head while contacting a film in which fine pores are formed and filling the pores with ink while simultaneously heating a thermal head and ejecting ink. The present invention relates to a recording device that performs serial recording.

[Conventional technology]

Many inkjet recording devices have been announced in the past, but they have not been put into full-scale practical use because they have not been able to completely solve the problem of nozzle clogging.

Therefore, the applicant proposed a recording device that uses a method that prevents nozzle clogging, in which a large number of fine holes are formed in the film, and the fine holes are used as nozzles to eject ink from the nozzles by heating a thermal head to perform recording. was first proposed (patent application 1982-
No. 178201). As shown in the drawings of the application, the applicant is currently researching and developing a recording device that prints by rotating a film with many microscopic holes endlessly and impregnating the circulating film with ink. They worked hard day and night to manufacture a cassette that had an endless film and an ink reservoir.

However, a cassette that is equipped with an endless film and an ink reservoir is expensive because it uses a large number of precision parts, and in addition, the circumferential length must be set small in order to store the film in the cassette. An unexpected problem occurred. In other words, if the film's circulating length is reduced, the film's circulating speed must necessarily be increased, and when the film's circulating speed is increased, the impregnation (supply) of ink to the film will be increased.
It was believed that this would cause a problem in which the process could not be performed smoothly. The applicant has focused on the above-mentioned conventional problems, and aims to smoothly supply ink to the film and record to the recording paper using a simple structure.

[Means for solving problems]

A recording device according to the present invention includes a longitudinal recording paper;
A long film with a large number of holes is arranged along the recording paper with one side facing the recording paper, and a long film is arranged on the other side of the film and parallel to the recording paper in sliding contact with the film. The moving body is composed of an ink supply body that supplies ink to each hole of the film while slidingly touching and moving against the film, and a large number of ink supplying bodies that are slidingly touching and moving against the film. The heating dot element selectively generates heat,
It is integrated into a cassette-like structure and includes a thermal head that selectively ejects ink supplied to the holes in the film toward the recording paper.

[Effect]

According to the present invention, a film is disposed in a longitudinal manner facing a longitudinal recording paper, and an ink supply body and a thermal head integrated in a cassette shape are placed in sliding contact with the recording paper. Since it is moved in parallel, the supply of ink to the film and the jetting (printing) of ink to the recording paper can be smoothly performed in one operation. That is, since ink is supplied more stably than in the conventional endless film that rotates at high speed, it is possible to reliably record on recording paper with a simple structure.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a perspective view illustrating the basic structure of the present invention;
FIG. 2 is a plan view of the same. 1 is a film;
A large number of holes 2 are formed in a thin metal film such as A or an organic film such as polyimide. This film 1 has an appropriate width and is formed into a long elongate shape. Although both ends of this film are not shown, it is wound into a roll, and when the used part deteriorates, a new part can be taken out and replaced with a new part wound on the roll, and it is extremely resistant to clogging. strong. On one side of the film 1, a recording paper 8 also having a longitudinal shape is placed facing the film 1. 3 is a thermal head portion in which a plurality of thermal dot elements 6 are formed. 4 is an ink supply section that supplies ink. This ink supply section 4 has a box-like cassette shape, and has an ink injection port through which ink can be injected, recording ink is contained in the ink supply port, and the ink is further supplied to the holes 2 of the film 1. In order to fill the holes with ink, an ink supply section 4a such as a sponge is in contact with one side of the film. The thermal head section 3 and the ink supply section 4 are integrated into a cassette shape to constitute a moving body. The moving object is film 1 at the time of recording.
It moves parallel to the recording paper 8 along the longitudinal direction of the film 1 while slidingly contacting the other surface. Then, ink 5 is sequentially supplied to the holes 2 of the film 1 from the ink supply section 4, and the supplied ink 5
The ink 5 is ejected onto the recording paper 8 by selectively generating heat from the thermal dot element 6 of the thermal head 3, using the hole 2 of the opposing film 1 as a nozzle to eject valve pressure in the direction of the recording paper 8. becomes possible. The ink 5 is newly supplied from the ink supply section 4 to the holes 2 of the film 1 from which the ink 5 has been ejected due to the movement of the moving body. Note that 7 is a flexible cable for transmitting signals from a drive circuit (not shown) to the thermal head 3. According to this embodiment, the ink supply section 4 is integrated into a cassette-like state facing the longitudinal recording paper 8.
Since the thermal head 3 is moved parallel to the recording paper 8, the supply of the ink 5 to the film 1 and the jetting (printing) of the ink 5 to the recording paper 8 are smoothly performed in one operation. It can be done.

That is, since the ink 5 is supplied more stably than the conventional endless film 1 which rotates at high speed, it is possible to reliably record on the recording paper 8 with a simple structure. .

FIG. 3 is a perspective view showing an embodiment in which color recording is performed. 8 is recording paper wrapped around the drum. Of course, it is also possible to use a method of running in one pass without winding it around the drum. 1a, 1b, 1c,
1d is a film corresponding to Y color, M color, C color, and B color. These are provided with a thermal head 3a and an ink supply section 4a as recording heads. Reference numeral 10 denotes a stand for supporting the recording head, through which a rod 9 for supporting the traveling of the recording head is connected. As the recording paper is scanned, a recording head for recording each color moves to record each color in the line direction.

〔Effect of the invention〕

As described above, the present invention has a very simple mechanism and is highly resistant to clogging of the nozzle.Even if the nozzle becomes clogged, recording can be performed immediately by winding and moving the film. Application to electronic typewriters and the like is extremely easy.
