BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording device and its manufacturing method.

[0002]

2. Description of the Related Art In recent years, in image recording of video cameras, televisions, computer graphics and the like, there is an increasing need for colorization of hard copy as well as recording of mono color. In response to this, various types of printers have been developed and deployed in various fields.

Among these recording methods, an ink sheet coated with an ink layer in which a high-concentration transfer dye is dispersed in a suitable binder resin, and a dyeing resin that receives the transferred dye are coated. The heat-sensitive recording head located on the ink sheet applies heat according to the image information, and the heat-sensitive recording head located on the ink sheet applies heat according to the image information. There is a method of thermal transfer.

The so-called thermal transfer system, which obtains a full-color image by repeating the above-mentioned operation for each of the image signals decomposed into yellow, magenta, and cyan, which are the three primary colors of subtractive color mixture, is compact and easy to maintain. Therefore, it is attracting attention as an excellent technology that has an immediacy and obtains a high-quality image comparable to a silver salt color photograph.

FIG. 31 is a schematic front view of the main part of such a thermal transfer type printer. According to this printer, a thermal recording head (hereinafter referred to as a thermal head) 1 and a platen roller 3 face each other, and an ink sheet 4 having an ink layer 4a provided on a base film 4b between them,
The recording paper (transferred material) 5 having the dyeing resin layer (dye receiving layer) 5a provided on the paper 5b is sandwiched and pressed against the thermal head 1 by the platen roller 3.

Then, the ink (transfer dye) in the ink layer 4a selectively heated by the thermal head 1 is transferred to the dyeing resin layer 5a of the transfer-receiving member 5 in a dot shape, and thermal transfer recording is performed. In such thermal transfer recording, generally, a line system in which a long thermal head is arranged orthogonally to the recording paper traveling direction and fixed and a serial system in which the thermal head reciprocates in a direction orthogonal to the recording paper traveling direction. Has been adopted.

By the way, the applicant of the present invention has been able to reduce the waste and the transfer energy, and to make the printer small and lightweight while taking advantage of the above-mentioned thermal transfer recording system.
We have already proposed a non-contact type dye vaporization type laser beam printer as shown in 32.

According to this recording method, a heat-fusible dye layer
A recording head (printing paper) 50 having a recording head (for example, a serial type printer head) 40 having 22 in the vaporizing section 17 and a receiving layer 50a for receiving the vaporized (or sublimated) dye 32.
A minute gap 17a in the range of 1 μm to 1 mm is provided between and.

Then, by irradiating the laser beam L, the liquefied dye stored in the dye storing portion 37 of the vaporizing portion 17 of the recording head 40.
22 is selectively heated to near its boiling point to be vaporized, the vaporized dye 32 is caused to fly in the void 17a, and transferred from the vaporization hole 23 onto the photographic printing paper 50 which is a recording medium to obtain continuous gradation. Get the image you have. This operation is the three primary colors of subtractive color, yellow,
Full colorization can be achieved by repeating each of the image signals decomposed into magenta and cyan.

In this recording method, the photographic printing paper 50 is opposed to the recording head 40, for example, on the upper side, and the laser light emitted from the laser 18 and condensed by the lens 19 is near the upper surface of the vaporizing section 17. It is advisable to irradiate L to cause the vaporized dye 32 to fly or move upward.

In this case, the transfer dye is emptied by the heating means.
In order to move 17a, in addition to the vaporization phenomenon, it is often seen when irradiated with a high-power laser, and the bonds of dye molecules are efficiently cut and the energy is used to etch at a very high rate. Phenomena and the phenomenon that gas energy generated by boiling or explosion is used to etch at a very high rate can also be used (a transfer mechanism other than such a vaporization mechanism is referred to as ablation: hereinafter the same).

Further, a head base having a laser beam transmitting property.
The dye reservoir 15 is provided on the head 14, and the liquefied dye 22 is housed between the head 13 and the lid 13 fixed on the head base 14.
The liquefied dye 22 is supplied to the vaporizer 17 via 27. in this case,
In order to improve the efficiency of supplying the dye to the vaporizing section 17 and the vaporizing efficiency, to prevent the dye from escaping due to a decrease in the surface tension of the dye caused by heat generation, and to continuously supply and hold the dye by utilizing the capillary phenomenon. Further, a bead aggregate 20 composed of small beads 21 is provided in the vaporization section 17.

A protective plate (not shown) is fixed on the lid 13 in order to hold the gap 17a and guide the photographic printing paper 50 moving in the X direction (the direction perpendicular to the paper surface). A heater for maintaining the liquefied state of the dye may be embedded in the protective plate. Here, the heater 26 is arranged in the dye containing portion (the passage 27).

The solid powder heat-meltable dye 42 in the solid dye storage tank 41 is supplied from a supply port 43 by a check valve 44,
It is heated to the melting point by the heater 26 and melted (liquefied). The liquefied dye 22 is supplied at a constant rate to the upper surface of the bead aggregate 20 of the vaporization section 17 at a high rate by the capillary phenomenon of the bead aggregate 20.

Further, the entire printer including this printer head is, for example, for full color as shown in FIG.
Yellow, magenta, and cyan dye reservoirs 15Y, 15M,
15C is provided on each common base 14 to form each dye supply section or supply head section 37Y, 37M, 37C, and from there, 12 to 24 dots of each color dye are formed in rows to form a vaporization section 17Y. , 17M, 17C.

For each vaporizing part, a large number of condenser lenses 19 are provided for each laser beam emitted from a multi-laser array 30 in which 12 to 24 corresponding lasers (particularly semiconductor laser chips) 18 are arranged in an array. The light is condensed by the microlens array 31 in which is arranged (36 is a mirror for guiding the laser light L in the perpendicular direction).

As the condenser lens, the illustrated lens system may be used, but a single large-diameter condenser lens 38 indicated by an imaginary line may be used. The lens 38 is formed so that the refraction path changes so that the light emission position corresponds to the vaporization parts 17C, 17M, and 17Y described above according to the light incident position.
The multi-laser array 30 is driven and controlled by the control IC 34 provided on the substrate 33, and the heat sink 35 is also provided.
Is designed to allow sufficient heat dissipation.

In the case of mono-color printing, as shown in FIG. 34, a one-dimensional laser array 30 is produced, and each laser element can be operated independently and in parallel. Printing speeds of more than one time can be obtained (for example, 24 times speed is obtained by using a laser array with 24 beams).

Each of the printer heads described above accommodates as many liquefied dyes 22 as the number of recording dots corresponding to the number of recording dots in the dye accommodating portion 37, and the laser 18 also has an array having light emitting points corresponding to the number of recording dots. It is arranged in a shape.
Even with the above thermal transfer printer that does not rely on the laser 18,
The heating units of the thermal head 1 are also arranged in a dot pattern.

As described above, according to this dye vaporization type laser beam printer, regarding the dye consumed for recording, only the lost portion is voluntarily or forcibly in the molten state from the dye reservoir to the vaporization part. By pouring, or
It can be continuously applied onto an appropriate substrate, and the substrate can be continuously supplied to the vaporizing unit by moving to the transfer unit. This is possible because the dye contains little binder resin. Therefore, since the vaporizing section involved in recording can be repeatedly used many times, the ink sheet is disposable only once in the above-mentioned thermal transfer method, which is advantageous in terms of resource saving and environmental protection.

Further, since it is a vaporization type or an ablation type, recording can be carried out without contact between the dye layer and the recording medium (printing paper), so that it can be seen in the above-mentioned thermal transfer system at the time of the second and subsequent printing. The reverse transfer of the dyes and the color mixture do not occur, and the heating portion is only the head including the vaporizing portion, and the power consumption is remarkably reduced as compared with the above-mentioned thermal transfer method. At the same time, the printer can be made smaller and lighter because a small volume dye reservoir is used for supplying the dye instead of the above-described ink sheet.

Further, since this recording system utilizes vaporization or sublimation of the dye, it is not necessary to heat the dye receiving layer of the recording medium as in the above-mentioned thermal transfer system, and the ink sheet and the recording medium are not recorded. It is not necessary to press the body against the body with high pressure, and this is also advantageous in reducing the size and weight of the printer. Since the dye layer in the vaporized portion and the recording medium do not come into contact with each other, heat fusion cannot occur between them, and recording is possible even if the compatibility between the dye and the receiving layer resin is small. Therefore, the range of design and selection of the dye and the resin for the receiving layer is remarkably expanded.

Further, the semiconductor laser 18 is basically used as a light source as a heat energy supply source for vaporizing (or sublimating) the dye, but the semiconductor laser has a high conversion efficiency from electric power to light. Since the dye has excellent directivity and light collecting property, the heat energy transfer efficiency of the dye is also very high. Therefore, the total energy utilization efficiency is markedly higher than that of the conventional method (thermal transfer by the above-mentioned thermal head or ink jet), which is advantageous in downsizing and power saving.

Further, in the conventional ink jet type color printer, it is difficult to express gradation, but since the semiconductor laser can easily control the output power, the pulse width and the like, the above recording method can easily express multi gradation. realizable. That is,
An electric image created by a color video camera or the like can be converted into a dye transfer corresponding to an image signal by a semiconductor laser to form a full-color image having at least 128 gradations per color, which is comparable to silver halide photography. it can.

The head 40, which is a transfer member suitable for the dye vaporization type recording method, has the property of sufficiently withstanding the amount of heat instantaneously applied at the time of transfer, and spontaneously due to the capillary phenomenon to the vaporization part (transfer part). It is preferable to have a structure (20 in FIG. 32) having a large surface area for supplying a liquid dye and capable of firmly holding the dye even during transfer.
Further, by providing an appropriate heat retaining device, it becomes possible to use a dye or a dye mixture having a melting point of room temperature or higher.

A transfer dye suitable for this recording method is
It has an appropriate vaporization rate or ablation rate, and shows a fluid state at 200 ° C or lower in a single or mixed state,
Any dye may be used as long as it has necessary and sufficient heat resistance. Specific examples thereof include disperse dyes, oil-soluble dyes, basic dyes and acid dyes. In particular, when the ablation mechanism is superior to the vaporization mechanism, a dye having a large molecular weight and a low vaporization rate, such as a direct dye,
Even carbon black and pigments can be transferred. Even for a dye having a melting point of room temperature or higher, the melting point is lowered by mixing the dyes with each other or by mixing the dye and a volatile low molecular weight substance.

Further, the photographic printing paper suitable for this recording method has a proper compatibility with the transfer dye, easily accepts the transfer dye, accelerates the original color development of the dye, and fixes the dye. Any photographic paper can be used. For example, for the disperse dye, a paper having a surface coated with a polyester resin, a polyvinyl chloride resin, an acetate resin, or the like, which has good compatibility with the disperse dye, is preferable. The fixing of the dye transferred onto the printing paper may be performed by heating the transferred image so that the transferred dye on the surface penetrates into the image receiving layer.

The heating means of the dye transfer system is roughly classified into a method using a thermal head, a material that absorbs laser light and a wavelength range including the wavelength range of the laser light, and converts light energy into heat energy (photothermal conversion). A method of combining a body (not shown) and laser light can be mentioned.

When a laser beam is used, the resolution is remarkably improved, and by increasing the laser beam density in the optical system, it becomes possible to perform intensive heating, and the ultimate temperature is increased. As a result, the thermal efficiency is improved. There is a feature called.
Particularly, by using the multi-laser, the time for transferring one screen is significantly shortened.

However, the photothermal converter must be sufficiently heat resistant in order to continuously absorb the laser light of light energy. Therefore, as the photothermal converter used in this system, a thin film type light absorber such as a metal thin film that exhibits absorption matching the emission wavelength of a laser, or a two-layer film of a metal thin film and a ceramic thin film having a high dielectric constant is directly transferred. In addition to being provided on the part, heat resistance such as fine particle type light absorbers such as carbon black and metal fine particles, organic dyes such as phthalocyanine dyes, naphthalocyanine dyes, cyanine dyes, anthraquinone dyes or organometallic dyes A dye or pigment having excellent properties may be used by uniformly dispersing it in a transfer dye.

It has a function of adjusting the temperature of the dye receiving layer 50a of the photographic printing paper 50 by the heat transfer of.

The photographic printing paper 50 is actually composed of a cellulosic resin or the like, and comprises a dye receiving layer 50a which absorbs disperse dyes, and a base material 50b. The base material 50b is formed by laminating a polypropylene layer having high heat resistance and good non-hygroscopicity, a base paper, and another polypropylene layer for balancing the polypropylene layer and preventing the photographic printing paper 50 from warping. The structure may be different, and a light absorption layer (which can be omitted) may be provided.

As shown in FIGS. 35, 36, and 38, the spacer 62 is provided with a plurality of square columnar holes 62a each of which is a part of the vaporizing hole 23 of each vaporizing section 17, and the dye Storage tank 41 (41Y for yellow, 41M for magenta, 41 for cyan

The above printer head shown in FIGS. 35 to 39.
According to 60, in addition to having the features described with respect to the printer head 40 shown in FIGS. 32 to 34, it has the following advantages when compared with this printer head 40.

First, since the heating of the dye for vaporization in each vaporization section 17 is performed not by using the laser light L but by the heat generation of the heating element 65 provided in each vaporization section, an expensive semiconductor laser ( In particular, it is possible to use a low-cost heating element instead of multiple laser arrays that are provided in parallel), and the vaporization efficiency directly uses the heat generated by the heater without depending on the electro-optical conversion efficiency of the laser. , The efficiency as a whole is improved.

In the printer head 60 shown in FIGS. 35 and 36, a heat insulating material block forming a part of the vaporization structure 81.
Since the 66 is fixed on the heater 68 in the hole 62a with an adhesive and separated from the spacer 62, the mechanical strength of the vaporization structure cannot be said to be sufficient.

Therefore, as shown in FIG. 40, a spacer 751
The vaporization structure 781 is integrally provided with the through hole 753 as a dye introduction path connecting to the vaporization structure 781 in the spacer 751 to eliminate the above-mentioned lack of mechanical strength.

However, as a result of the inventor's examination of the printer head of FIG. 40, it was found that the following points to be improved remain.

Each of the above-mentioned parts is a minute size part. For example, in the printer head 700 shown in FIG. 40, the diameter of the dye introduction path 727 is as small as 0.1 μm. Since there is no simple method to do so, it is complicated to form a groove as the dye supply passage 727 on the back side, reduce the plate thickness of this part, and then provide a through hole 753 by a special processing method such as powder beam etching. Various steps are required. Moreover, since it is a thin plate, it is easily broken and has poor workability. Further, when the dye introduction path 727 is processed by wet etching, it is very difficult to mask the dye supply path 727 that has been processed in advance.

When a large step is provided between the vaporizing portion and the wiring terminal, it is necessary to cut a large amount of spacers by fine processing. Therefore, the poor workability as described above is a factor of high cost.

As a porous structure. The void 92 holds the liquefied dye 22 in the housing portion 87 by its capillary action, and
It serves to supply a sufficient amount of the liquefied dye 22 necessary for the time-series operation of one dot of the printer to the upper side (vaporization surface or liquid surface).

A heating element 65 having a thickness of, for example, 1 μm or less is provided in the center of the width of the small pillar body group so as to be in contact with the lower surface of the small pillar body 80.

The heating element 65 is made of a silicon compound such as carbon or polysilicon, is formed on the bottom surface of the dye containing portion 87, and has a pair of aluminum electrodes 69 on both sides thereof.
A and 69B are provided.

A signal voltage based on an image signal is applied between the electrodes 69A and 69B by matrix driving, and the energization generates heat at 50 to 500 ° C. in the heating element 65, and this heat efficiently heats the liquefied dye 22. To vaporize. Then, under the insulating plate 56, a second glass made of high melting point glass is used.
Since the material layer 51 and the first material layer 62 made of ceramics are integrally provided, they act as a heat insulating material, and the heat generated by the heating element 65 is hardly dissipated.

The first material layer 62 and the second material layer 51 include
An introduction passage 53 for the liquefied dye 22 is formed by branching from the common dye passage 27, and the introduction passage 53 opens at the side surface of the dye containing portion 87.
Therefore, the liquefied dye 22 is continuously introduced into the dye containing portion 87 via the dye introduction path 53 and is supplied to the vaporization structure 101.

It should be noted here that layers are formed in order from the material farther from the printing paper 50 in order of higher heat treatment temperature,
The second material layer 51 is partially provided on the first material layer 62 made of ceramics to form a step, the vaporizing portion 17 is provided on the projecting portion, and the connecting terminal 69a of the heating element 65 is provided on the concave portion. That is, the space between the vaporizing portion and the printing paper is narrowed by securing a space for connection.

Therefore, it is possible to construct an efficient process when processing the dye containing portion 87, the columnar body 80, the dye introducing path 53, etc., without causing cracks or breakage, and handling and reliability. Moreover, the yield and cost performance can be improved.

Further, since the columnar body 80 and the dye accommodating portion 87 are formed by etching the insulating plate 56 on the second material layer 51 to form the vaporization structure 101, this is formed by an adhesive. Unlike the method of fixing individually, only the alignment at the time of masking is required, so the columnar body 80 and the dye accommodating part
87, and the dye introduction path 53 can be easily and accurately processed by using a separate resist, and the recording characteristics can be improved.

The first material layer 62 further includes a dye channel.
Since it is bonded and fixed to the base material 63 made of a quartz glass plate having 27, the base material 63 acts as a reinforcing material, and the mechanical strength of the head is further sufficient.

A small columnar body is formed on a part of the protrusion having the step.
A group of 80 is arranged at a predetermined interval, and a liquid stop band 55 is provided so as to surround each group of the small pillars 80 to form each vaporization part region. The liquid retaining band 55 is made of a fluorine-based or silicon-based material and prevents the liquefied dye 22 from flowing out. Further, a spacer 52 made of low-melting glass is provided so as to sandwich the region of the vaporizing section 17 to maintain a gap between the vaporizing section 17 and the printing paper.

The vaporizing section 17 in which the main part is formed is
The printer heads 70 are arranged as shown in FIG. The solid powdery heat-meltable dye 42 in the solid dye tank 41 shown in FIG. 3 is heated to a melting point or higher by the heater 68 and liquefied, passes through the dye passage 27, communicates with the dye passage 27, and vaporizes 17 respectively. It is supplied to the dye accommodating portion 87 of each group of the small pillars 80 via the dye introducing path 53 provided for each.

The vaporizing section 17 configured as described above is shown in FIG.
-In FIG. 3, one or two dots are shown, but the head 70
In practice, a plurality of dots are arranged for each color (yellow Y, magenta M, cyan C) for full color, as shown in FIGS. 33 and 37 to 39. Therefore,
In this case, the structures of FIGS. 1 to 3 are arranged in a line.

When color printing the photographic printing paper 50,
Heat is generated by the heating element 65 according to the image signal. Due to this heat, the dye in each vaporization portion is vaporized, fly through the gap 92 between the vaporization structure 101 and the printing paper 50, and are transferred to the receiving layer 50a of the printing paper 50 in the order of Y, M, and C.

The printer head 70 according to this embodiment is shown in FIG.
Similar to the head 60 shown in (4), it is of a thermal transfer system that heats the dye 22 to fly to the printing paper 50 through the gap,
It has the features of miniaturization, ease of maintenance, immediacy, high-quality images, and high gradation described above.

Although the small columns 80 are made of SiO ₂ , they can be made of other materials. For example, a polymer material such as polyimide, a ceramic material, a silicon material, a metal material, or a combination thereof can be used. The polymer material can be formed because it does not press the printer head 70 against the printing paper 50, and therefore it does not receive a large pressure, and the heat dissipation during the operation of the heating element 65 is small. , Thermal insulation becomes good.

Next, an example of a method of manufacturing the head 70 according to this embodiment will be described with reference to FIGS.

First, as shown in FIG. 4, solid powdery raw material ceramics is compression molded into a powder compact 62A of 0.8 to 1.0 mmt (thickness), and a through hole 53 to be a dye introduction path is provided. Sintering forms the first material layer 62. Ceramic green compact shrinks when sintered, so holes of about 0.1 mmφ can be easily drilled.

Next, as shown in FIG. 5, the through holes 53 provided in the first material layer 62 are filled with a resist 57 to fill the through holes 53, and the upper surface thereof is sputtered to form a heat-resistant material and SiO 2 for closing the through holes. _Two layers 54 are formed to a thickness of about 2 μm, and through holes 53
The resist 57 filled in is removed.

Next, as shown in FIG. 6, a partial band-shaped high-melting-point glass glaze is printed on the upper part of the through hole 53 by a printing method.
The raw second material layer 51A is formed by stacking the layers to a thickness of about 100 μm. This width is preferably about 2 to 4 mm.

Then, as shown in FIG. 7, the stacked raw second
This material layer 51 is baked at about 900 ° C. to form the second material layer 51, and the surface thereof is polished to make the surface. Second like this
The material layer 51 is partially raised in order to secure a space for wiring terminal connection and to improve the image quality by making the gap between the vaporizing part and the printing paper small and transferring before the vaporized dye diffuses. This is because

Then, as shown in FIG. 8, the material P-Si (polysilicon) 65A for forming the heating element is plasma C.
A film is formed by VD and annealed at about 600 ° C.

Next, as shown in FIG. 9, the P-Si layer 65A is patterned to form the heating element 65.

Next, as shown in FIG. 10, aluminum (Al) 69, which is a material for electrodes and wiring, is vapor-deposited to form a film.

Then, as shown in FIG. 11, the excess aluminum film portion is removed by patterning, and electrodes 69A and 69B are removed.
And terminal portions 69a and 69b are formed.

Then, as shown in FIG. 12, a heating element 65 and an electrode 69 are provided.
An insulating film 58A made of SiO ₂ is formed on the entire surface including A, 69B and the terminals 69a, 69b by sputtering for insulation to a thickness of 0.1 μm or less.

Then, as shown in FIG. 13, a layer 58B of an etching control material made of chromium or nickel is formed on the insulating film 58A.
Is formed by sputtering. This layer is for forming a step between the post-shaped body and the heating element 65, which will be described later, and is made of a metal whose etching rate is slower than that of the SiO ₂ layer 56 provided next on this layer.

Then, as shown in FIG. 14, a material layer 56 made of SiO ₂ for forming the vaporizing structure for flying dye 101 is laminated. This thickness is preferably 3 to 6 μm.

Next, as shown in FIG. 15, first, FIG.
As shown in the plan view, metal masks 85 and 83 for forming the group of small pillars 80 and the liquid stop groove 55a are formed by vapor deposition, and Si of 1 μm or less is formed on the metal masks 85 and 83 to protect them.
O _{2 is formed} into a film. In FIG. 15 (b), reference numeral 85 is a small pillar body.
A mask for forming 80, and liquid stopper grooves 55a for 84a and 84b as well.
It is a mask for formation. FIG. 15A shows a state in which the mask 83 thus manufactured covers the surface of the uppermost layer 56. Although not shown, the mask 83 is provided with a cutout portion for a spacer, which will be described later.

Then, as shown in FIG. 16, a hole 71a for forming the dye introducing path 53 is formed on the metal mask 83 provided in the previous step.
Forming a resist 71 having

Then, as shown by the arrow in FIG. 17, the second material layer 51 in contact with the first material layer 62 made of ceramics is wet-etched by using the first material layer 62 as a resist. , Resist for other parts
By performing wet etching from the 71 side, the penetrating dye introducing path 53 is easily formed. At the time of this wet etching, the etching control material layer 58B has a slower etching rate from the up and down direction, which prevents the inner diameter from significantly expanding when penetrating the dye introduction path 53.

Then, the resist 71 is removed as shown in FIG. 18, and thereafter, as shown in FIG. 19, a low melting point glass (450 ° C.) is laminated on the upper surface after the dye introducing path 53 is formed by a printing method. By firing, the glaze spacers 52 are formed on the cutout portions of the mask described above with reference to FIG.

Then, as shown in FIG. 20, the columnar body 80 and the liquid stop groove 55a are formed by reactive ion etching (RIE) using the metal mask 83 previously provided as a mask, and the connection terminals 69a and 69b are formed. To form. At the time of forming the small pillars, as described above, the etching control material layer 58B having a low etching rate is present below the small pillar-constituting material layer 56, including on the heating element 65. The etching can be stopped when the control material layer 58B is completely etched.

Therefore, as shown in the enlarged view of the portion A in FIG. 1, the etching control material layer 58B remains below the small pillar 80,
The etching control material layer on the heating element 65 is removed, and the pillar body 80 is removed.
The height difference between the surfaces of the heating element 65 and the heating element 65 is promoted by the thickness of the etching control material layer. As a result, the level difference between the two becomes large, and the amount of liquefied dye on the heating element increases, so that the recording is efficiently performed by the vaporization. The liquid stop groove 55 is filled with a fluorine-based or silicon-based material to form the liquid stop band 55.

Next, since the aggregate of head members is formed by the above steps, this is divided into individual parts as shown in FIG. 21 to complete the manufacturing process of a single head member. Then, this is joined to a separately manufactured base material 63 having the dye passage 27, and integrated to complete a printer head.

By the manufacturing process as described above, a step is formed between the columnar body 80 and the heating element 65 because the etching control material layer is provided on the heating element 65 and the like. The second material layer 51 and the spacer 52 may be made of a heat-resistant polymer material or a metal material instead of the glass material.

As described above, by providing the through-holes before sintering the ceramics, this hole processing can be performed easily and the number of steps can be greatly reduced. Further, by using constituent materials having different heat treatment temperatures, it becomes possible to sequentially stack each layer. Furthermore, since the second material layer is formed by glaze printing, it is possible to easily form a step between the vaporization portion and the wiring terminal. Therefore, the bulge of the wire connection portion in the terminal portion is also absorbed by this step, so that the distance between the vaporizing portion and the printing paper is shortened accordingly, the image quality is improved, and a highly reliable vaporizing portion structure is obtained.

FIG. 22 is a schematic sectional view of the essential parts showing a modification of the first embodiment. As shown in the figure, the printer head 90 according to the present embodiment uses a heating beam (laser beam) L as the heating means for vaporizing the liquefied dye 22 in place of the heating element 65 in the first embodiment. Unlike the first embodiment, the other parts have the same structure.

In this recording method, the above-described FIG. 32 and FIG. 33 are used.
Similarly, the laser light L emitted from the laser 18 and condensed by the lens 19 is irradiated to vaporize the liquefied dye 22. After that, the method in which the vaporized dye flies upward and is transferred to the photographic printing paper 50 is the same as that by the heating element.

Therefore, in this system as well, the same effects as those of the first embodiment can be obtained, and the number of man-hours required for producing the heating element for each vaporization section is significantly reduced although the laser-related equipment is additionally provided. It

23 to 25 show a second embodiment of the present invention, FIG. 23 is a plan view of the main part of the printer head 100, FIG. 24 is a sectional view taken along the line XXIV-XXIV of FIG. 23, and FIG. It is the XXV-XXV sectional view taken on the line.

The feature of this embodiment is that a common dye reservoir 93 is provided at a position adjacent to a plurality of vaporizing parts 17. The liquefied dye 22 is replenished to the dye reservoir 93 from the dye passage 27 through the dye introducing passage 95 common to each vaporizing section, and each vaporizing section 17 is supplied.
The liquefied dye 22 is supplied from the dye reservoir 93 through the dedicated dye supply port 94 at the shortest distance. That is, in this example, the dye introducing path 95 and the dye reservoir 93 constitute the recording material introducing path.

As shown in the figure, the head 110 has the same structure as that of the first embodiment except for the dye reservoir 93, the dye supply port 94 and the dye introduction path 95 described above. That is, since the common dye reservoir 93 is provided at a position adjacent to each vaporizing section 17, the dye introducing passages 95 are provided at, for example, two locations on both ends, thereby reducing the number of manufacturing steps and shortening the dye supply port 94. As a result, the supply efficiency of the liquefied dye 22 can be increased.

Therefore, according to this example, as described above, as compared with the first embodiment, the number of dye introduction paths is reduced and the manufacturing man-hours are reduced, thereby reducing the manufacturing cost and liquefying. By efficiently supplying the dye 22,
Good recording can be realized and reliability can be further improved. Also in this example, as shown in FIG. 22, it is possible to adopt a heating beam system, and the same effect as in the example of FIG. 22 can be obtained.

26 to 28 show a modification of the second embodiment. FIG. 26 is a plan view of the main part of the printer head 110, FIG. 27 is a sectional view taken along line XXVII-XXVII of FIG. 26, and FIG. Same as XXVIII-XXVI
It is a II sectional view.

The difference of this embodiment from the second embodiment is that
That is, the dye supply port 94 in the second embodiment is not provided. That is, in this example, the dye reservoir 96 is expanded to the area of the dye supply port 94 in the second embodiment, and the dye reservoir 96 is expanded.
A communication port 97 is provided at the boundary between the vaporization structure 110 and the direct vaporization structure 110 for communication.

Therefore, according to this example, the dye supply efficiency is further improved because the resistance due to the liquefied dye passing through the narrow dye supply port is reduced, and the dye supply port is compared with the second embodiment. The effect of reducing the number of man-hours for providing 94 will be added. Also in this example, the heating beam system can be adopted similarly to the second embodiment, and in such a case, the same effect as the above can be obtained.

Each of the printer heads according to the above-described examples has the same function. For example, a color video printer 200 having the printer head 70 can feed paper in the vertical direction (X direction) as shown in FIG. , The X direction and the horizontal direction (Y direction) scan of the head in the orthogonal direction perform printing, and the vertical paper feed and the horizontal head scan are alternately performed.

In the printer 200, the printer head 70 including the head portions Y, M, and C of each color is a serial type head, and the head feed shaft 201 including a feed screw mechanism.
The head support shaft 202 allows the print paper 50 to reciprocate in the head feed direction Y which is orthogonal to the paper feed direction X.

A head receiving roller (platen roller) 203 that supports the printing paper 50 so as to sandwich the printing paper 50 is rotatably provided above the printer head 70. The photographic printing paper 50 is sandwiched between the paper feed drive roller 204 and the driven roller 205 and moved in the paper feed direction X.

When the printing of one line is completed, the printing paper 50 is fed by one line by the paper feed drive roller 203 which also serves as a head support. Printing is started sequentially for each color, but after 3 dots, printing is performed simultaneously. If there are multiple heating elements 65, they are operated alternately, and the selected heating element 65 is used for printing, while the non-printing heating element 65 uses residual heat to liquefy and retain heat of the dye. However, the temperature can be controlled.

FIG. 30 shows a color video printer 200 having a head 70 of a line type, in which head portions Y, M and C of respective colors are arranged side by side in the width direction of the photographic printing paper 50. .

Although the embodiments of the present invention have been described above, the above embodiments can be further modified based on the technical idea of the present invention.

For example, when laminating each layer of the laminated body constituting the recording apparatus, the treatment temperature of the layers is lowered in the order of laminating, part of the layers is treated at the same temperature, or part of the layers is laminated. It is also possible to process at a temperature slightly higher than the layer immediately below.

Further, the second material layer and the spacer may be made of a heat-resistant polymer material or a metallic material instead of the glass material, and the heating element 65 may be made of any other material. It can also be formed by a combination of.

Further, the porous structure formed in the vaporization part is not limited to the above-mentioned ones. For example, in the case of a columnar body, the height, cross-sectional shape and density may be changed. It can also be formed of a body or a fibrous body.

Further, the number of dye containing parts and the number of dots containing dyes, and the corresponding number of heating elements and vaporizing parts can be changed, and the shape and size of the array are also limited to the above. Instead, a transfer method or a transfer method by ablation is also possible.

Further, the dye passage may be provided not in the base material but in the first material layer, and the structure and shape of the head and the printer may be appropriate structures and shapes other than the above. Further, with respect to the dye, it is also possible to perform recording in full color in which black is added in addition to the above-described three primary colors, as well as in two colors, one color of mono color or black and white.

Further, as the heating means for vaporizing the dye, a combination of the above heating element and a laser can be used. In this case, good vaporization can be obtained even if the power of the heating means is lowered.

In addition to the above dyes, solid dyes can be heated by laser light to be vaporized directly for recording, and laser light can be irradiated from above the head to position the printing paper on the lower side. It is also possible to record.

The present invention also supplies a recording liquid containing a recording material and a substance which dissolves or disperses the recording material and expands in volume by heating, and the state of the recording liquid is changed by heating to form droplets. It is also applicable to an ink jet system in which the liquid droplets are generated and the droplets are transferred to a recording medium arranged opposite to the recording head.
