Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer device having a print head which mixes and ejects a first recording liquid and a second recording liquid. Specifically, by forming these nozzles for ejecting the recording liquid on the pair of main surfaces of the base member having a pair of main surfaces intersecting each other at a predetermined angle, it is possible to suppress printing defects and improve reliability. The present invention relates to a printer device which can be easily manufactured and has high productivity.

2. Description of the Related Art In recent years, especially in offices and the like, document creation using a computer called desktop publishing has become popular, and recently, not only letters and figures but also a natural color like a photograph is displayed. There is also an increasing demand for outputting images together with characters and figures. Along with this, it is required to print a high-quality natural image, and reproducing halftones is becoming important.

Further, a so-called on-demand type printer device, in which ink droplets are ejected from nozzles to print on a print medium such as paper or film only when necessary in accordance with a print signal, is small in size and low in cost. Since it can be made into a new material, it is rapidly spreading in recent years.

Various methods have been proposed for discharging ink droplets as described above, and a method using a piezo element or a method using a heating element is generally used.
The former is a method in which pressure is applied to ink to discharge it by deformation of a piezo element. The latter is a method in which the ink is ejected at a pressure of bubbles generated by heating and boiling the ink by the heating element.

Various methods have been proposed as a method for reproducing the above-mentioned halftone with the above-mentioned on-demand type printer device for ejecting ink droplets. That is, the first method is to control the size of a droplet to be ejected by changing the voltage or the pulse width of the voltage pulse applied to the piezo element or the heating element, and to express the gradation by changing the diameter of the print dot. To be

However, according to this method, if the voltage or pulse width applied to the piezo element or the heating element is too low, ink cannot be ejected, so that the minimum droplet diameter is limited, and the number of gradation stages that can be expressed is small. Expression of low density is difficult, and it is not enough to print out a natural image.

As a second method, one pixel is constituted by a matrix of, for example, 4 × 4 dots without changing the dot diameter, and gradation expression is performed in a unit of this matrix using a so-called dither method. Method. In this case, expression of 17 gradations is possible.

However, in this method, for example, when printing is performed at the same dot density as in the first method, the resolution becomes the first.
And the roughness is conspicuous, which is insufficient for printing out a natural image.

[0009]

Therefore, the inventors of the present invention control the density of printed dots by changing the density of the discharged ink droplets by discharging the diluted liquid and the ink while mixing them. It has been proposed to provide a printer device of a system that enables to achieve the above, expresses gradation without causing deterioration of resolution, and prints out a natural image.

An example of such a printer device is a printer device which mixes ink and a diluting liquid to form a mixed liquid having a predetermined concentration and then ejects the mixed liquid. An example of a print head of such a printer device is shown in FIG.

As shown schematically in FIG. 26, this print head is connected to a liquid chamber 102 in which a diluting liquid 104 is introduced into the main body 101, and is connected to the liquid chamber 102 to form one main surface 1 of the main body 101.
The nozzle 103 is formed so as to open toward 01a.
A supply port 107 for supplying the ink 105 from the liquid chamber 106 filled with is connected. In addition,
As shown in FIG. 26, a supply groove 108 is formed on the opposite side of the nozzle 103 of the liquid chamber 102, which serves as a connection port for an external diluent supply unit.

That is, in this print head, the ink 105 is quantitatively added from the supply port 107 to the diluting liquid 104 inside the nozzle 103 to form a mixed liquid having a predetermined concentration, and the above-mentioned mixed liquid is discharged from the nozzle 103. Printing is performed by ejecting the mixed droplets 109.

However, in a printer having a print head which mixes the ink 105 and the diluting liquid 104 in the nozzle 103 to form a liquid mixture having a predetermined concentration, the ink 105 and the diluting liquid 104 naturally stand by during printing. It is likely to mix. When such natural mixing occurs, the density control accuracy at the time of printing is deteriorated, which causes a print defect, and the reliability is greatly impaired.

Therefore, there has been proposed a printer device having a print head in which a valve is provided at the opening of the supply port so as to prevent natural mixing of the ink and the diluting liquid during printing standby. Such a print head is shown in FIG.
And the like.

This print head has substantially the same structure as the print head shown in FIG.
As schematically shown in FIG. 27, the pressure chamber 113 into which the diluting liquid 112 is introduced into the main body 111 and the nozzle 1 communicating with the pressure chamber 113 and opening toward the one main surface 111 a of the main body 111.
14 is formed, and in the middle of this nozzle 114,
A supply port 117 for supplying the ink 115 from the liquid chamber 116 filled with the ink 115 is connected to the inside. In this print head, the valve 1 that can be opened and closed is provided at the connection portion of the supply port 117 with the nozzle 114.
18 are provided.

That is, in this print head, the valve 118 is closed during the print standby,
The diluting liquid 112 in the nozzle 114 and the ink 115 in the supply port 117 are completely isolated by the valve 118, and natural mixing is prevented.

However, in the print head having such a structure, the structure is complicated and the manufacturing is complicated, so that the productivity is not so good. Further, the operation of the valve is also regulated as necessary, the operation as the printer device is increased, and the operation mechanism and the control device are also complicated correspondingly, and the manufacturing is complicated, so the productivity is not very good. .

In order to eliminate such inconvenience, FIG.
8 and a printer device having a print head as schematically shown in FIG. 29 have also been proposed. Here, an example of a printer device having a so-called carrier-jet type print head in which the ink is used as a fixed amount side and the discharge side is used as a diluting liquid will be described.

That is, as shown in FIG. 28, the first pressure chamber 142 into which the diluting liquid is introduced, the first nozzle 143 communicating with the first pressure chamber 142, and the ink are provided on the side of the one main surface 141a of the base member 141. The first and second recesses 146 and 147 forming the second pressure chamber 144 to be introduced and the second nozzle 145 communicating with the second pressure chamber 144 are respectively the first and second recesses 146.
The formation direction of the second recess 147 is oblique with respect to the formation direction of the first nozzle 143 and the second nozzle 145.
Are formed so that their opening tips are close to each other.

Then, as shown in FIG. 29, a vibration plate 149 is disposed on one main surface 141a, which is a recess forming surface of the base member 141, with an adhesive layer 148 interposed therebetween. Therefore, the first and second recesses 146, 147 and the diaphragm 149
The space surrounded by the first pressure chamber 142 and the first pressure chamber 142
Nozzle 143, second pressure chamber 144 and second nozzle 1
45 will be formed respectively.

Further, in this print head,
First and second pressure chambers 146, 147 on the diaphragm 149
A piezoelectric element (not shown) such as a piezo element is provided at a position corresponding to, and the deformation of the piezoelectric element enables pressurization to the first and second pressure chambers 142 and 144.

That is, in order to perform printing by the printer device having such a print head, first, the second pressure chamber 144 is pressurized by a piezoelectric element (not shown) so that a mixed liquid having a predetermined concentration can be formed. A predetermined amount of ink is oozing out from the second nozzle 145 toward the first nozzle 143, and then the first pressure chamber 142 is pressurized by a piezoelectric element (not shown),
The diluting liquid coming out of 3 is mixed with ink to form a mixed liquid, which is discharged toward a printing medium such as paper and adhered to perform printing.

Although such a print head has a simple structure and is easy to manufacture, the pressure applied to the ejection side may be propagated to the adjacent fixed amount side, and the ejection side nozzle and the fixed amount side nozzle are opened. There is the inconvenience that it is not possible to easily change the angle formed by the parts, the so-called mixing angle.

Therefore, the present invention has been proposed in view of the conventional circumstances, and an object of the present invention is to provide a printer device which is less likely to cause printing defects, has high reliability, is easy to manufacture, and has good productivity. To do.

[0025]

In order to solve the above-mentioned problems, a printer apparatus according to the present invention has a print head, one main surface of a base member having a pair of main surfaces intersecting at a predetermined angle. At least one first nozzle into which the first recording liquid is introduced is formed so as to face the end portion in the cross direction, and the second recording liquid is introduced into the other main surface side. It is characterized in that at least one second nozzle is formed so as to face the end portion in the intersecting direction.

In the printer of the present invention,
At least one of the first nozzle and the second nozzle may be formed on the base substrate bonded to the main surface of the base member.

Further, in the printer device of the present invention, it is preferable that the first pressure chamber and the second pressure chamber are connected to the opposite sides of the opening faces of the first nozzle and the second nozzle, respectively. .

Furthermore, in the printer apparatus of the present invention, the ejection ports are provided at the end portions of the print head facing the first nozzles and the second nozzles, and at positions corresponding to the first nozzles and the second nozzles. It is preferred that an orifice plate having a is arranged.

Further, in the printer device of the present invention,
The first nozzle and the second nozzle may be configured by a space formed by forming a recess of a predetermined shape on the pair of main surfaces of the base member and disposing a lid member thereon. , A resin material layer having a through hole of a predetermined shape is laminated on each of the pair of main surfaces of the base member, and a lid member is arranged on the resin material layer to form a space formed by blocking the upper and lower sides of the through hole. May be.

Further, in the printer device of the present invention, it is preferable that the first recording liquid and the second recording liquid are ink and diluent.

In the printer device of the present invention, the first recording liquid is introduced into the print head on one main surface side of the base member having a pair of main surfaces intersecting at a predetermined angle. At least one nozzle is formed so as to face the end portion in the cross direction, and the second nozzle is formed on the other main surface side.
It is assumed that at least one second nozzle into which the recording liquid is introduced is formed so as to face the end portion in the intersecting direction.

Therefore, at the time of printing, for example, the second recording liquid is ejected from the second nozzle toward the first nozzle, adhered to the vicinity of the first nozzle and quantified, and then the first nozzle The first recording liquid is discharged together with the second recording liquid adhering to the vicinity of the first nozzle to adhere to the recording material.

That is, since the first and second recording liquids are mixed outside the nozzle, the first recording liquid is kept in standby during printing.
The natural mixing of the second recording liquid and the second recording liquid hardly occurs.

Further, since the first nozzle and the second nozzle are respectively formed on the pair of main surface sides of the base member which intersect at a predetermined angle, the openings of the first nozzle and the second nozzle are formed. It is not necessary to make these shapes different in order to bring them close to each other, and the manufacturing is easy. By changing the angle of the base member, the angle formed by the openings of the first nozzle and the second nozzle, that is, the so-called mixing angle, can be easily changed.

Further, since the first and second nozzles are formed on the different surface sides of the base member respectively, a plurality of nozzles of the same type may be formed on one main surface side even in the case of multi-heading. Easy to manufacture.

Furthermore, in the printer device of the present invention, at least one of the first nozzle and the second nozzle may be formed on the base substrate bonded on the main surface of the base member. In this case, the first nozzle and the second nozzle can be manufactured separately, which facilitates the manufacturing. Further, since the nozzles manufactured separately are combined, if one of the nozzles is defective, it may be replaced, and the manufacturing yield as a whole is improved.

In the printer of the present invention,
Even if the first pressure chamber and the second pressure chamber are respectively connected to the opposite sides of the opening surfaces of the first nozzle and the second nozzle,
Since it is formed on the same main surface side of the base member as the first and second nozzles, it is manufactured without increasing the number of steps. In this case, since the first pressure chamber and the second pressure chamber are formed on different main surfaces, the pressure applied to the discharge side pressure chamber is propagated to the pressure applied to the fixed amount side pressure chamber. Nor.

Further, in the printer device of the present invention, ejection ports are provided at positions corresponding to the first nozzle and the second nozzle on the end side of the print head facing the first nozzle and the second nozzle. If the orifice plate is provided, the discharge port is made of the same material.
The ejection stability of the first and second recording liquids from the second and second nozzles is improved.

Further, by disposing the orifice plate as described above, it becomes easy to align each print head when disposing a plurality of print heads so that each color can be ejected.

At this time, the print paper 1 is placed on the drum 2
The paper is pressed and held on the drum 2 by a paper pressure roller 4 provided in parallel to the axial direction. A feed screw 5 is provided near the outer periphery of the drum 2 in parallel with the axial direction of the drum 2. The print head 3 is held by the feed screw 5. That is, the print head 3 is configured to move in the axial direction of the drum 2 as indicated by an arrow M in the figure by the rotation of the feed screw 5.

On the other hand, the drum 2 includes a pulley 6, a belt 7,
It is rotationally driven by a motor 9 via a pulley 8 as indicated by an arrow m in the figure. Further, the rotation of the feed screw 5 and the motor 9 and the print head 3 are driven and controlled by the head drive, head feed control, and drum rotation control 10 based on the print data and the control signal 11.

In the above arrangement, the print head 3
When is moved to print one line, the drum 2 is rotated by one line to print the next line. When the print head 3 moves and prints, it may be unidirectional or reciprocal.

As a liquid jet recording apparatus equipped with the printer apparatus of the present invention, there is also a so-called line type apparatus having a structure as shown in FIG. As shown in FIG. 2, this liquid jet recording apparatus has substantially the same configuration as the liquid jet recording apparatus shown in FIG. 1, is held by a feed screw 5, and the drum 2 is rotated by the feed screw 5. Instead of the print head 3 which is movable in the axial direction, a print head 12 in which a plurality of print heads are fixed and arranged in the axial direction of the drum 2 is arranged. That is, in the print head 12, printing for one line is performed simultaneously, and when printing for one line is performed, the drum 2 is rotated by one line to perform the next printing. Further, in this case, it is possible to print one line at a time, divide one line into a plurality of blocks, or alternately print every other line.

A block diagram of a printing and control system in such a liquid jet recording apparatus is shown in FIG. The signal input 21 such as print data is input to the signal processing control circuit 22,
The signal processing control circuit 22 arranges them in the printing order and sends them to the head 24 (print head) via the driver 23. The printing order differs depending on the configuration of the head 24 and the printing unit, and also has a relationship with the input order of the printing data. If necessary, the printing order is temporarily recorded in a memory 25 such as a line buffer memory or a one-screen memory and then taken out. To the head 24, a gradation signal and an ejection signal are input.

When the number of nozzles is very large in a multi-head, an IC is mounted on the head 24 to reduce the number of wirings connected to the head 24. Further, a correction 26 is connected to the signal processing control circuit 22 so that γ correction,
Color correction in the case of color, variation correction of each head, and the like are performed. In the correction 26, the predetermined correction data is
It is generally stored in the M map format and taken out in accordance with external conditions such as nozzle number, temperature, and input signal.

The signal processing control circuit 22 includes a CPU and a DSP.
Generally, the processing is performed by software, and the processed signal is sent to various control motor drives and the like 27. In various control motor drive and others 27, control such as drive of a motor for rotatingly driving a drum and a feed screw, synchronization, cleaning of a head, supply and discharge of print paper, and the like are performed. Further, it goes without saying that the signals include an operation unit signal other than print data and an external control signal.

Next, the printer device of this example will be described. As shown in FIG. 4, the print head used in the printer device of this example has a plurality of piezoelectric elements 33 such as piezoelectric elements arranged on one main surface 31a, which is an upper surface, via a vibration plate 32, and is not shown. A first base substrate 31 in which the nozzle faces the one main surface 31b serving as the front surface and an opening, and a plurality of piezoelectric elements 43 such as piezo elements are arranged on the one main surface 41a serving as the upper surface via a vibration plate 42. The second base substrate 41, which is open so that the nozzle (not shown) faces the one main surface 41b serving as the front surface, is provided with the base member 34 so that the nozzle openings are close to each other.
It is pasted together via. In addition, the first
Between the base substrate 31 and the diaphragm 32 and between the second base substrate 41 and the diaphragm 42 by adhesive layers 38 and 48, respectively.
1 and the base member 34 are also bonded by an adhesive layer (not shown).

One main surface 31a of the first base substrate 31
On the side, as shown in FIG.
Pressure chamber 35 and one main surface 31b which is in front of and communicates with this pressure chamber 35
A concave portion 39 is formed to form a first nozzle 36 facing the opening and a supply groove 37 on the opposite side of the first pressure chamber 35 from the first nozzle 36. This is the same on the one main surface 41a side of the second base substrate 41, and the second pressure chamber, the second nozzle, and the concave portion for forming the supply groove are formed.

Then, the first and second base members 3
The vibrating plate 3 is provided on the base plate 1, 41 with the adhesive layers 38, 48 interposed therebetween.
By disposing 2, 42, the space surrounded by the recess 39 and the diaphragm 32 and the recess and the diaphragm 42 is the supply groove, the first pressure chamber, the first nozzle, or the supply groove, the second pressure chamber, Second
The nozzle will be configured.

Further, as shown in FIG. 5, the above-mentioned plurality of piezoelectric elements 33 shown by broken lines in the figure correspond to the plurality of first pressure chambers 35 via a vibration plate (not shown). It is located in. In this case, the first pressure chamber 35
Is substantially rectangular in a plane, the piezoelectric element 33 disposed thereon is also substantially rectangular in a plane.

That is, when the print head is viewed from the piezoelectric element 33 side, the diaphragms 33 having a substantially rectangular plane are arranged side by side on the diaphragm 32 as shown in FIG. 6, and from one side surface side. Looking at it, as shown in FIG.
In the figure, only the first base substrate 31 side is shown. ), The strip-shaped piezoelectric element 33 is arranged on the vibration plate 32 on the one main surface 31a of the first base substrate 31.

In the print head of this example,
As shown in FIG. 8, the base member 34 is assumed to have a pair of main surfaces 34a, 34b intersecting each other at a predetermined angle θ ₁ , and _one main surface 34a of the pair of main surfaces 34a, 34b. To the first side from the supply groove 37 as shown in FIG.
The first base chamber 31 in which the first pressure chamber 35 into which the recording liquid is introduced and the first nozzle 36 communicating with the first pressure chamber 35 is formed is arranged, and on the other main surface 34b side, in FIG. A second pressure chamber 45 into which the second recording liquid is introduced from a supply groove 47 as shown, and a second base substrate 41 in which a second nozzle 46 communicating with the second pressure chamber 45 is formed are arranged between them. Are bonded by an adhesive layer (not shown).

As described above, the first nozzle 36 and the second nozzle 36
Of the nozzle 46 of the first and second base substrates 31 and 41 are opened so as to face the main surfaces 31b and 41b which are the front faces of the first and second base substrates 31 and 41.
A pair of main surfaces 34a intersecting with a predetermined angle theta ₁ of the base member 34, if distribution respectively on 34b, as shown in FIG. 9, the angle theta ₁ by the first and second base members 34 The openings of the nozzles 36, 46 of the first main surface 34a, 34b
As described above, they are close to each other as they face the end portion in the crossing direction. However, in order to make the first principal surfaces 31b and 41b facing and opening the first and second nozzles 36 and 46 into a single continuous plane, the first principal surface 31b is a vertical surface and the first principal surface 41b is the above-mentioned first principal surface. It is an inclined surface that can form a plane with the surface 31b.

In the print head of this example,
The angle θ ₁ of the base member 34 was 62 °, the sizes of the first nozzle 36 and the second nozzle 46 were the same, and the distance between the centers of the first nozzle 36 and the second nozzle 46 was 50 μm.

The angle θ ₁ of the base member 34 may be any angle that allows the openings of the first nozzle 36 and the second nozzle 46 to be close to each other, and is preferably 5 ° to 90 °, preferably 10 °.
It may be in the range of ° to 75 °.

The above-mentioned first nozzle 36 and second nozzle 46
Does not necessarily have to be the same size. For example, the nozzle for fixed quantity may be 1.5 times as large as the other nozzle, and the size of the discharge nozzle may be 50 μm × 25 μm (width × width).
Depth), the size of the metering nozzle is 75 μm ×
An example is 25 μm (width × depth).

The size of the first and second nozzles 36 and 46 is such that the width is 5 to 200 μm, preferably 20 to 80.
μm, depth 5-100 μm, preferably 15-50 μm
It may be in the range of m.

However, as the width and depth of the nozzle increase, the size of the discharged droplet also naturally increases, so the width and depth can be set so that a droplet of a desired size can be formed. preferable. In addition, since the discharged droplets try to form a spherical shape due to the surface tension,
The shapes of the second nozzles 35 and 46 may be rectangular or circular in cross section.

When manufacturing the print head of this embodiment, the recesses 37, 37 are formed in the first and second base substrates 31, 41.
Examples of means for forming 47 include machining by an end mill and the like, processing by half etching, and the like. In addition, here, the first and second base substrates 3 are
A glass substrate having a thickness of 500 μm is used as 1, 41, and the first and second base substrates 31, 41 are provided with recording liquid supply paths from the outside (not shown), and serve as a reinforcing member for the print head. I tried to make it stupid.

The first and second base substrates 31, 41
Adhesive layers 38, 4 for bonding the diaphragms 32, 42 on top
Examples of the constituent material of No. 8 include ordinary liquid adhesives and the like, and it is preferable that the constituent material is formed as thin as possible within the range where the necessary adhesive strength is obtained. Here, the thickness is set to about 1 μm. The adhesive layers 38 and 48 can also be formed by a dry film resist, but if they are too thick, deformation of the piezoelectric element may be hindered, so it is better to be thin, for example, about 15 μm. In this case, as the vibrating plates 32 and 42, nickel plates having a thickness of 10 μm are used, but it is preferable that the plates are as thin as possible, and it may be about 8 μm.

The above first and second base substrates 31, 41
As the constituent material of the diaphragms 32 and 42, a material having good water resistance may be used if the recording liquid used is water-soluble, and a material having good oil resistance may be used if the recording liquid used is oily. , Stainless steel, nickel and the like.

Further, as the piezoelectric elements 33 and 43, the above-mentioned piezoelectric elements and the like can be cited. An example of such a piezo element is a laminated piezo element in which a piezoelectric material and a conductive material are alternately laminated, and one in which the laminating direction is parallel to the in-plane direction of the diaphragms 32 and 42 and the other in the laminating direction are The first and second base substrates 31 and 41 may have a direction perpendicular to the in-plane directions of the vibrating plates 32 and 42, and any of these may be used. It should be noted that both of them expand in the stacking direction when a voltage is applied.

Therefore, the former laminated piezo element extends in the laminating direction when a voltage is applied, so that it extends in the in-plane direction of the first and second base substrates 31 and 41, but in the direction orthogonal thereto. It will shrink. Therefore, this laminated piezo element does not apply pressure to the pressure chamber. Such a piezo element is called a d ₃₁ mode.

On the other hand, in the latter laminated piezoelectric element,
When a voltage is applied, it extends in a direction orthogonal to the in-plane direction of the first and second base substrates 31 and 41 and applies pressure to the pressure chambers. Such a piezo element is called a d ₃₃ mode.

In such piezoelectric elements 33 and 43, it is preferable that the width thereof is narrower than the width of the first and second pressure chambers 35 and 45 because the vibration plates 32 and 42 are easily deformed. . For example, when the pitch between the plurality of pressure chambers is 300 μm, one piezoelectric element has a width of 200 μm.
If the pitch is divided into 300 μm with a blade of m, a plurality of piezoelectric elements with a width of 100 μm will be formed.

Next, the operation when printing is performed by the printer device of this example and the timing of applying the drive voltage to the piezoelectric element will be described together. In addition, here, the first nozzle 3
An example in which 6 is used as a discharge nozzle, the second nozzle 46 is used as a metering nozzle, and d ₃₃ mode laminated piezoelectric elements are used as the piezoelectric elements 33 and 43 will be described. An example of a carrier jet method in which a diluent is used as the recording liquid on the ejection side and ink is used as the recording liquid on the fixed amount side will be described.

That is, FIG. 10 (a) and FIG. 10 (b)
As shown in (1), no voltage pulse is applied to the first and second piezoelectric elements 33 and 43 at the time of standby before printing, at the time shown by (A) in the figure.

At the time of printing, based on the signals from the head drive, head feed control, and drum rotation control 10, the ink is first pushed out from the second nozzle 46 as shown in FIG. 10B. In order to output the driving voltage V ₂ to the second piezoelectric element 43 at the time shown by (B) in the figure,
Is added at time t ₂ , the second piezoelectric element 43 is expanded to pressurize the second pressure chamber 45, and the ink is pushed out to the second nozzle 46 side. As a result, as shown in FIG.
9 bleeds from the outside of the second nozzle 46 to the vicinity of the opening of the first nozzle 36, and quantitative determination is performed. At this time, the diluent 50 forms the first meniscus D ₁ on the opening side of the first nozzle 36.

The drive voltage V ₂ is variable and is, for example, 2 at maximum.
It may be about 0 [V], and the time t ₂ is, for example, 0.
It may be set to 1 ms, and as a drive voltage application pattern, the pressure is gradually raised so that the ink gradually bleeds onto the first and second base substrates 31 and 41, and then held in that state, and then the first voltage is applied. And a pattern in which the pressure is gradually lowered so that the ink remains on the second base substrates 31 and 41.

At the time point indicated by (C) in FIG. 10B, since the drive voltage to the second piezoelectric element 43 is zero, the pressurization to the second pressure chamber 45 is also zero, Ink is drawn into the second nozzle 46. As a result, FIG.
As shown in FIG. 2, the ink 49 discharged on the one main surface 41 b of the second base substrate 41 and the one main surface 31 b of the first base substrate 31 and in the vicinity of the opening of the first nozzle 36 is left,
The second meniscus D ₂ is newly formed in the nozzle 46.

Further, in this state, in order to discharge the diluting liquid 50 from the first nozzle 36, the first piezoelectric element 33 is driven from the time point shown in (D) to the time point shown in (E) of FIG. The voltage V ₁ is applied at time t ₁ to extend the first piezoelectric element 33 and pressurize the first pressure chamber 35 to press the first nozzle 36.
Push the diluent to the side. As a result, as shown in FIG. 13, the diluting liquid 50 is extruded from the first nozzle 36, and the droplet 51 of the mixed liquid with the ink 49 remaining in the vicinity thereof is formed.
Is ejected, and this is deposited on the above-mentioned printing paper 1 and printing is performed.

The drive voltage V ₁ is, for example, 15 [V] at maximum.
The time t ₁ is, for example, 0.05 ms.
The driving voltage is preferably applied as a rectangular wave in order to expel the diluting liquid vigorously.

At the time point indicated by (E) in FIG. 10A, since the drive voltage to the first piezoelectric element 33 is zero, the pressurization to the first pressure chamber 35 is also zero, The diluent 50 is drawn into the first nozzle 36. After this, the first
The internal pressures of the pressure chamber 35 and the first nozzle 36 return to their original values before long, and at the time point indicated by (F) in FIG. 10A, the diluent 50 is refilled in the first nozzle 36 due to the capillary phenomenon. As shown in FIG. 13, a first meniscus D ₁ is newly formed.

Then, as shown in FIGS. 10A and 10B, printing is performed by repeating the above operation. In this case, the difference between the start of applying the drive voltage to the second piezoelectric element 43 and the start of applying the drive voltage to the first piezoelectric element 33, that is, the time indicated by t ₃ in FIG.
3 ms, and the operation frequency indicated by f in the figure is 30
It is set to 0 hertz.

As the ink used in the printer device of this example, the following compounds may be used, and the diluting liquid may be water.

(Ink Formulation) Dye (CI Direct Yellow 87) 3 parts by weight Isopropyl alcohol 5 parts by weight Glycerin 2 parts by weight Diethylene glycol 6 parts by weight Water 84 parts by weight As described above, in the printer device of this example. is a print head, a pair of main surfaces 34a intersecting with a predetermined angle theta _1, on one main surface 34a side of the base member 34 having a 34b, a first recording liquid is introduced 1
First base substrate 31 in which at least one nozzle 36 is opened so as to face one main surface 31b in the intersecting direction.
And a second nozzle 46 into which the second recording liquid is introduced is formed on the other main surface 34b side so that at least one second nozzle 46 is formed so as to face the one main surface 41b in the intersecting direction. The base substrate 41 is arranged.

Therefore, at the time of printing, as described above, for example, the second recording liquid is supplied from the second nozzle 46 to the first nozzle 36.
Second recording in which the first recording liquid is adhered to the vicinity of the first nozzle 36, and then the first recording liquid is adhered to the vicinity of the first nozzle 36 for quantitative determination. It is discharged together with the liquid and adhered to the recording material.

That is, since the first and second recording liquids are mixed outside the nozzle, the first recording liquid is kept in standby during printing.
The recording liquid of No. 2 and the second recording liquid are less likely to be naturally mixed with each other, print defects are less likely to occur, and reliability is good.

In addition, the first nozzle 36 and the second nozzle 4
6 are formed on the side of the pair of main surfaces 34a, 34b that intersect each other at a predetermined angle of the base member 34.
It is not necessary to make these shapes different in order to bring the openings of the nozzle 36 and the second nozzle 46 close to each other, and the manufacturing is easy and the productivity is good. By changing the angle of the base member, the angle formed by the openings of the first nozzle and the second nozzle, that is, the so-called mixing angle, can be easily changed.

Further, the first surface is formed on the different surface of the base member 34.
Since the first and second base substrates 31 and 41 on which the first and second nozzles 36 and 46 are respectively formed are arranged, it is sufficient to form a plurality of nozzles of the same type on one base substrate in the case of multi-heading. , Easy to manufacture and good in productivity.

Furthermore, in the printer apparatus of this example, since the print head is constructed by bonding the first and second base substrates 31 and 41 to the base member 34 as described above, Since each base substrate to be formed can be manufactured separately, manufacturing is facilitated and productivity is improved.

Furthermore, since the products manufactured separately are combined, if the base substrate on which one nozzle is formed is defective, it may be replaced and combined with another product. The manufacturing yield is improved and the productivity is improved.

Further, in the printer apparatus of this embodiment, the first pressure chamber 35 and the second pressure chamber 45 are connected to the opposite sides of the opening faces of the first nozzle 36 and the second nozzle 46, respectively. Although formed, the first and second nozzles 3
It is formed in the same manner as Nos. 6 and 46, is manufactured without increasing the number of steps, and has good productivity. In this case, since the first pressure chamber and the second pressure chamber are formed on different main surfaces, the pressure applied to the discharge side pressure chamber is propagated to the pressure applied to the fixed amount side pressure chamber. Nor.

In the print head of the printer of this example, a resin material layer having through holes for forming nozzles, pressure chambers and supply grooves is arranged on a base member or base substrate, and a diaphragm is arranged thereon. It is also possible to use a print head in which the space formed by closing the through hole from the up and down direction is used as a nozzle, a pressure chamber and a supply groove.

As described above, the dry film resists 68 and 78 have through holes (not shown) for forming the supply groove, the pressure chamber and the nozzle, which are formed by closing the through holes in the vertical direction. The space is used as a supply groove, a pressure chamber and a nozzle.

In the print head of this example, the ejection port 63 (only a part of which is shown in FIG. 14) is provided at a position corresponding to the first and second nozzle opening positions (not shown). The orifice plate 73 is arranged on the side of the one main surface 68a, 78a facing the openings of the first and second nozzles (not shown) as shown by the arrow A in the figure.

In the print head of this example as well,

Also in the print head of this example, the size of the angle θ _{2 and} the size of the nozzle may be in the same range as those of the print head described above, and the shape of the nozzle is also the same.

In the print head of this example,
A glass substrate having a thickness of 500 μm was used as a base substrate, a dry film resist for a permanent mask having a thickness of 25 μm was used as a dry film resist, and a nickel plate having a thickness of 10 μm was used as a vibrating plate. Also in the print head of this example, as the constituent material of the base substrate and the diaphragm, the same materials as those of the above-mentioned print head can be mentioned.

Further, also in the print head of this example,
A piezoelectric element is used in the same manner as the print head described above, and the piezoelectric element described above can be used as this piezoelectric element. And here, according to the pitch of the pressure chamber,
The pitch of one piezoelectric element is 300μ with a blade of 180μm width
What was cut so that it might become m was used. Therefore, the operation and the application timing of the drive voltage when printing are the same.

Such a print head is manufactured as follows. First, as shown in FIG. 15, a first base substrate 61 having a predetermined size is prepared and, for example, 50 ° C.

By heating and pressurizing under the condition of J / cm ² for 60 minutes, the first base substrate 61 and the vibration plate 62 are bonded by the dry film resist 68 as shown in FIG. At this time, the through-hole portion 69 of the dry film resist 68 is blocked by the base substrate 61 and the vibration plate 62 from above and below, and the space surrounded by these allows the supply groove, the first pressure chamber, and the first nozzle to be separated. It is formed. The heating and pressurizing conditions should be determined in consideration of the curing conditions of the dry film resist used, the nozzle width, the combination of the recording liquid and the dry film resist used, and the like.

It is also possible to use one in which the vibration plate 92 is laminated on one main surface 84b via the dry film resist 98 having a through hole portion.

In this print head, a first nozzle (not shown) facing one main surface 88a is formed by closing the through hole of the dry film resist 88 from above and below with the first base substrate 81 and the diaphragm 82. By closing the through-hole portion of the dry film resist 98 with the base member 84 and the diaphragm 92 from above and below, the main surface 9
A second nozzle (not shown) that faces 8a is formed. The base member 84 may have a tapered shape formed by the pair of main surfaces 84a and 84b.

Even in the print head in which the space formed by closing the through hole of the dry film resist from above and below is used as the supply groove, the pressure chamber, and the nozzle, the concave portion of the base member or the base substrate described above is formed. Similar to a print head that is closed by a diaphragm to form nozzles and the like, during printing, for example, from the second nozzle to the second
Recording liquid is exuded toward the first nozzle and adhered to the vicinity of the first nozzle for quantification, and then the first recording liquid is adhered to the vicinity of the first nozzle from the first nozzle. The second recording liquid is discharged together with the second recording liquid to adhere to the recording material.

That is, since the first and second recording liquids are mixed outside the nozzles, the first recording liquid is kept in standby during printing.
The recording liquid of No. 2 and the second recording liquid are less likely to be naturally mixed with each other, print defects are less likely to occur, and reliability is good.

Further, since the first nozzle and the second nozzle are respectively formed on the pair of main surface sides of the base member which intersect at a predetermined angle, the openings of the first nozzle and the second nozzle are formed. It is not necessary to make these shapes different from each other in order to bring them closer to each other, and the manufacturing is easy and the productivity is good. By changing the angle of the base member, the angle formed by the openings of the first nozzle and the second nozzle, that is, the so-called mixing angle, can be easily changed.

Further, since the first and second nozzles are arranged on the different surface sides of the base member respectively, when the multi-head is formed, nozzles of the same kind are formed on one main surface side of one base substrate or base member. It suffices if a plurality of them are formed, the manufacturing is easy, and the productivity is good.

Furthermore, among these printer devices,
When the print head is configured by bonding a base substrate to a base member, the base substrate or the base member on which each nozzle is formed can be manufactured separately, which facilitates manufacturing and improves productivity. Will be good.

Furthermore, since the products manufactured separately are combined, if the base substrate or the base member on which one nozzle is formed is defective, it may be replaced and combined with another product. The manufacturing yield as a whole is improved and the productivity is improved.

In the printer of this example, the first nozzle and the second nozzle are provided with the first nozzle on the side opposite to the opening surface side.
The pressure chamber and the second pressure chamber are connected to each other, but they are formed in the same manner as the first and second nozzles, are manufactured without increasing the number of steps, and have good productivity. . In this case, since the first pressure chamber and the second pressure chamber are formed on different main surfaces, the pressure applied to the discharge side pressure chamber is propagated to the pressure applied to the fixed amount side pressure chamber. Nor.

Further, in these print heads, since the orifice plates having the ejection openings are arranged at the positions corresponding to the first and second nozzles, the ejection openings are made of the same material, and therefore the first ejection head is formed. And the ejection stability of the first and second recording liquids from the second nozzle is improved,
Printing defects are less likely to occur and reliability is increased.

When the orifice plates as described above are arranged, even when a plurality of print heads are arranged so that each color can be ejected, a plurality of print heads are formed in advance on one orifice plate. This makes it easier to align the print heads and improves productivity.

In the above example, the example of the print head in which the nozzles and the like are formed by closing the through holes of the dry film resist from above and below is described.
A base substrate having nozzles is arranged only on one main surface side of the base member as described above, and nozzles are directly formed on the other main surface side, or nozzles are directly formed on both main surface sides of the base member. It goes without saying that such a shape can also be applied to a print head in which a concave portion is formed in a base member or a base substrate, and this is closed by a diaphragm to form nozzles and the like. Further, also in the print head which forms the nozzles and the like by closing the concave portion in this way, the effect as described above can be obtained by disposing the orifice plate.

As is apparent from the above description, in the printer apparatus of the present invention, the print head has one main surface side of the base member having a pair of main surfaces intersecting at a predetermined angle. , At least one first nozzle into which the first recording liquid is introduced is formed so as to face the end portion in the intersecting direction, and the second recording liquid is introduced into the other main surface side. It is assumed that at least one second nozzle is formed so as to open so as to face the end portion in the intersecting direction.

Therefore, at the time of printing, for example, the second recording liquid is ejected from the second nozzle toward the first nozzle, adhered to the vicinity of the first nozzle and quantified, and then the first nozzle ejects the second recording liquid. The first recording liquid is discharged together with the second recording liquid adhering to the vicinity of the first nozzle to adhere to the recording material.

That is, since the first and second recording liquids are mixed outside the nozzle, the first and second recording liquids are mixed with each other during printing standby.
The natural mixing of the second recording liquid and the second recording liquid is unlikely to occur, and printing defects and the like are less likely to occur, and the reliability is high.

Further, since the first nozzle and the second nozzle are respectively formed on the pair of main surface sides of the base member which intersect at a predetermined angle, the openings of the first nozzle and the second nozzle are formed. It is not necessary to make these shapes different from each other in order to bring them close to each other, which facilitates the manufacture and improves the productivity. By changing the angle of the base member, the angle formed by the openings of the first nozzle and the second nozzle, that is, the so-called mixing angle, can be easily changed.

Further, since the first and second nozzles are formed on the different surface sides of the base member respectively, in the case of multi-heading, it is sufficient to form a plurality of nozzles of the same type on the one main surface side. It is easy and the productivity is good.

Furthermore, in the printer apparatus of the present invention, at least one of the first nozzle and the second nozzle may be formed on the base substrate bonded on the main surface of the base member. In this case, the first nozzle and the second nozzle can be manufactured separately, which facilitates manufacturing and improves productivity.

Further, since the nozzles manufactured separately are combined, if one of the nozzles is defective, it may be replaced, and the manufacturing yield as a whole is improved and the productivity is improved.

Further, in the printer device of the present invention,
Even if the first pressure chamber and the second pressure chamber are respectively connected to the opposite sides of the opening surfaces of the first nozzle and the second nozzle,
Since it is formed on the same main surface side of the base member in the same manner as the first and second nozzles, it is manufactured without increasing the number of steps, and the productivity is good. In this case, the first
Since the pressure chamber and the second pressure chamber are formed on different main surfaces, the pressure applied to the discharge side pressure chamber does not propagate to the pressure applied to the fixed amount side pressure chamber.

Further, in the printer apparatus of the present invention, ejection ports are provided at positions corresponding to the first nozzles and the second nozzles on the end side of the print head facing the first nozzles and the second nozzles. If the orifice plate is provided, the discharge port is made of the same material.
The ejection stability of the first and second recording liquids from the second and second nozzles is improved, printing defects are less likely to occur, and reliability is increased.

Further, by disposing the orifice plate as described above, it becomes easy to align each print head when disposing a plurality of print heads so as to eject each color.
