BACKGROUND of INVENTION

The technical field to which the invention relates

This invention relates to a head, throwing the liquid to eject the liquid, such as ink, which is filled with the discharge chamber, producing holes through the use of the power-generating element, such as electrothermal converting element or a piezoelectric element.

Description of the prior art

In a conventional recording device, release the liquid, the ink fed to the cylinder, expelling the liquid from the ink tank. The cylinder, expelling the fluid ejects ink toward the recording medium. In the cylinder, expelling ink, the pressure chamber is filled with ink through the feed hole. The ink, which is filled with the pressure chamber, are emitted from the emitting holes using a power-generating element, a typical example of which is the electrothermal converting element or a piezoelectric element. Then refill the ink in the pressure chamber through the feed hole, that is the so-called replenishment.

As a way to prevent the ingress of foreign substances in the pressure chamber to above the head, throwing the liquid is, there is a method involving the formation of two feed holes for ink associated with one release hole, both the feed holes of the ink is less than said one-emitting hole (see Japanese laid patent application No. 2001-71502).

With regard to the phenomenon of having a negative impact on the ejection of ink in the head, release the liquid, then there is the phenomenon of so-called cross-liability - in which the pressure wave generated by the power generating element extends into the other pressure chamber, in addition to the phenomenon in which a foreign substance gets into the pressure chamber. When the ink flow passage is narrowed, the flow of ink is suppressed by viscous resistance of the surface, and therefore cross-interference is attenuated. However, when the flow resistance of the ink increases, decreases rate of replenishment, and therefore it is impossible to increase the frequency of ejection of ink. More specifically, when the attempt to weaken the cross-interference, it is impossible to improve performance.

The INVENTION

The cylinder, expelling the liquid, includes: a substrate that includes a power generating element for generating energy used to eject liquid, and serves the her hole which is a through hole for supplying the liquid to energogeneriruyuschimi element; and a plate with holes, including throwing out the hole to eject the liquid, with a lot of energy generating elements located in the first direction, and the feed hole is formed between the multiple energy generating elements in the first direction, and that the feed hole is formed so that it is located next to the power generating element in a second direction perpendicular to the first direction.

DETAILED description of the INVENTION

Before describing embodiments of the present invention below with reference to Fig.12-14, describes the configuration of the recording device, releasing the fluid applies the cylinder, expelling the liquid, according to this invention.

The configuration of the recording device producing liquid

In Fig.12 presents a perspective representation illustrating the basic internal configuration of the recording device 100, throwing liquid on which you installed the cylinder, expelling the liquid, according to this invention. In Fig.13 shows a perspective image in question on the underside of the head 19, releasing the fluid installed at the recording device 100, releasing the fluid, is illustrated in Fig.12. In Fig.14 shows a perspective image with a spatial separation of the components discussed above head 19 which emit fluid, is illustrated in Fig.13.

In the recording device 100, releasing the fluid, is illustrated in Fig.12, the printed material is placed on the tray 11, and the cylinder 19, expelling the liquid, mounted on the carriage 22. The recording medium is transported through zapisywa the developing device 100, expelling the fluid in the direction of transport (see Fig.12). The carriage 22 performs reciprocating motion in the direction of a main scan is perpendicular to the direction In transportation. Thus, the head 19, releasing the fluid also makes the reciprocating movement in the direction of a main scan. As is illustrated in Fig.14, the cylinder 19 which emit fluid, installed with the possibility of removing some of the tanks 24 ink.

The first option exercise

In Fig.1 shows a view in plan, illustrating the main part of the head, throwing the liquid according to the first embodiment of this invention. As is illustrated in Fig.1, the cylinder 19, expelling the liquid, according to this variant implementation of the formed groups C1, M1, Y, M2 and C2 matrices nozzles. Groups C1 and C2 matrices nozzles are used to eject the cyan ink. Group C1 matrices nozzles includes two matrices La and Lb nozzles. Group C2 matrices nozzles includes two matrices Li and Lj nozzles. Group M1 and M2 matrices nozzles are used to eject Magenta ink. Group M1 matrix of nozzles includes two matrices Lc and Ld nozzles. Group M2 matrix of nozzles includes two matrix Lg and Lh nozzles. Group Y matrix of nozzles used to eject yellow ink and VK is uchet two matrix Le and Lf nozzles.

In Fig.2 shows in enlarged scale a view in plan of a matrix Ld nozzles, which is one of the above matrices nozzles. In Fig.3 shows a view in section, taken along the line 3-3 shown in Fig.2. In Fig.4 shows a view in section, taken along the line 4-4 shown in Fig.2. As is illustrated in Fig.3 and 4, the head 19, expelling the liquid, according to this variant implementation includes a supporting element 1, the substrate 2 and the plate 3 with the holes. The supporting element 1, the substrate 2 and the plate 3 with holes can share all matrices of nozzles in the head 19, releasing the fluid. In Fig.1 and 2 shows in plan without plate with 3 holes.

Between the support element 1 and the substrate 2 are formed a few General chambers 4 of the liquid corresponding to the respective groups of matrices. In every common fluid chamber 4 serves ink from the reservoir 24 of the ink. Ink supplied to the common fluid chamber 4, fill the chamber 5 of the liquid through several feed openings 2A passing through the substrate 2. Camera 5 fluid is formed between the substrate 2 and the plate 3 with the holes. In this embodiment, multiple feed holes 2A are arranged in the Y-direction matrix nozzles (see Fig.2). The substrate 2 has several energy-generating elements 6 formed therein for generating system is of energy, used to eject the liquid, which are located in the Y-direction matrix nozzles. In this embodiment, energy-generating elements 6 are electrothermal converting elements (heaters) to generate heat when they are by posting 10 (see Fig.2) is powered on. In the plate with 3 holes formed emitting holes 7 that are in positions where they are converted to the respective energy generating elements 6.

In the group of matrices M1 nozzles several energy-generating elements 6 and emitting holes 7 are located in the matrices Lc and Ld nozzles with a specified step P (see Fig.1). In addition, the energy-generating elements 6 and emitting holes 7 in the matrix Lc nozzles are shifted from energy-generating elements 6 and emitting holes 7 in the matrix Ld nozzles on the half-step (P/2) (see Fig.1). Thus, images can be recorded with a resolution that is twice the resolution per step P-emitting holes 7 in the matrices Lc and Ld nozzles. In this embodiment, the matrices Lc and Ld nozzles several feed openings 2A are arranged with a pitch P is the same as the step energy-generating elements 6 and emitting holes 7, and are arranged in an alternating, side by side with the energy generating elements 6. The same can be KazATO other groups C1, Y, M2 and C2 matrices nozzles.

In the head 19, expelling the liquid, the group C1 matrices nozzles and group C2 matrices nozzles are arranged such that they are symmetric with respect to the group Y matrices nozzles, and groups M1 and M2 are matrices of nozzles are arranged such that they are symmetric with respect to the group Y matrices nozzles, and this ensures the implementation of the so-called records in two directions. Thus, when the cylinder 19, expelling the liquid, makes a reciprocating motion (see arrows A1 and A2, shown in Fig.1), the head 19 which emit a liquid can throw ink of yellow, cyan, and Magenta colors in order to record high-quality images with reduced color unevenness. Energy-generating elements 6 and emitting holes 7 in group C1 matrices nozzles are shifted from energy-generating elements 6 and emitting holes 7 in the matrix C2 nozzles 1/4 step P (P/4). Similarly, the energy-generating elements 6 and emitting holes 7 in the group M1 matrix of nozzles are shifted from energy-generating elements 6 and emitting holes 7 in the matrix M2 nozzles 1/4 step P (P/4).

In the chamber 5 of the liquid area in front of the power-generating element 6 and emitting holes 7 functions as a pressure chamber R. More specifically, the camera 5 fluid includes several pressure Cham is R, communicating with each other. Each pressure chamber R is filled with ink through the feed hole 2A of the common fluid chamber 4. In this embodiment, each pressure chamber R in the chamber 5 of the liquid has several nozzle filter 8. Each nozzle filter 8 is columnar element. The gap S between the columnar elements (see Fig.2) corresponding to the width of the opening of nozzle filter 8, is smaller than the aperture D of each release hole 7 (see Fig.3). This can prevent in the pressure chamber R of foreign substance particles which are larger than throwing out the hole 7.

In this embodiment, both ends of the feed holes 2A in the X direction perpendicular to the direction Y matrices nozzles, are in the direction of the Y matrices nozzles, leaving the width d needed for installation wiring 10. In the head 19, releasing the liquid and having such a configuration, the energy-generating elements 6 are forced to generate heat based on the data records for the formation of bubbles in the ink in the pressure chamber R. Then the ink in the pressure chamber R is emitted from the emitting holes 7 through which the energy of the formation of bubbles. The pressure chamber R after throwing ink refill ink, located in the common fluid chamber 4 through the feed hole at back is their 2A. When the head 19 which emit fluid, installed on a specific recording device 100, releasing the fluid, is illustrated in Fig.12, the sequential scanning system, the image can be written as follows. The image can be recorded on the recording medium by repeating an operation of the ejection of ink from the release holes 7 and the operation of transporting the recording medium in the direction of transport with simultaneous movement of the head 19, releasing the fluid in the direction of a main scan. Near each power generating element 6 in the direction of the Y matrices nozzles are two feed holes 2A. Therefore, through these two feed holes 2A can quickly refill the pressure chamber R ink. When each group of matrices of nozzles includes at least two matrices nozzles, as in this embodiment, the pressure chamber R can be refilled with ink through two feed holes 2A, adjacent to the power generating element 6 in the direction X, and two feed holes 2A, adjacent to the power generating element 6 in the direction of the Y matrix of nozzles. Consequently, it is possible to increase the rate of replenishment. Accordingly, in addition you can further improve performance by increasing cha is Tautou ejection of ink.

The length of the feed holes 2A in the X direction is greater than the length of the power-generating element 6 in the direction X. Thus, the pressure generated upon excitation of the power-generating element 6 is sufficiently absorbed by the wide feed opening, and therefore it is possible to weaken the influence of the pressure in the pressure chamber adjacent in the Y-direction matrix nozzles.

In particular, in this embodiment, two feed holes 2A surround four sides of the power-generating element 6 with the exception of the site that hosts the wiring 10, and therefore the pressure chamber R can be quickly refilled with ink. More specifically, after the ejection of ink in the pressure chamber R, due to bubbles in the ink on energogeneriruyuschey element 6, the pressure chamber R is faster to refill ink through two feed holes 2A, intermittently surrounding four sides of the power-generating element 6. In addition, these two feed holes 2A effectively absorb the pressure of bubbles generated at energogeneriruyuschey element 6. Thus, it is possible to weaken the cross-interference. In the case where the matrix group of nozzles includes two matrices nozzles, as in this embodiment, both ends of both of the feed holes 2A, adjacent to the power generating element 6 in the direction Y Mat is CI nozzles, and both feed holes 2A, adjacent to the power generating element 6 in the direction of the X matrix nozzles will be able to absorb the pressure of the bubbles in the pressure chamber R. Thus, it is possible to weaken the cross-interference, acting in the direction X of the matrix nozzles, as well as cross-interference, acting in the direction of the Y matrix of nozzles. The head 19, expelling the liquid, according to this variant implementation can satisfy both requirements - increase recharge rates and attenuation crosstalk, which usually contradict each other.

In addition, in the head 19, expelling the liquid, according to this variant implementation, through nozzle filter 8 can be prevented from entering into the pressure chamber R foreign substances such as dust, already got through the feed hole 2A. Therefore, proper state of ejection of ink can be maintained stably. In addition, the feed hole 2A is located between the two pressure chambers R adjacent to each other in the Y-direction matrix of nozzles, and therefore the feed hole 2A is shared between these two pressure chambers R. Thus, the size of the substrate 2 can be reduced compared with a configuration in which multiple feed holes 2A are performed separately for each pressure chamber R. In rez is ltate can also reduce the size of the head 19, throwing out the liquid.

As described above, the high-quality image can be recorded with a high speed by increasing the frequency of ejection of ink, while increasing productivity and giving feed hole 2A can effectively absorb the pressure generated in the pressure chamber R, to reduce crosstalk. In addition, the high-resolution image can be recorded in two directions through a group of matrices nozzles, formed by two matrices nozzles, as illustrated in Fig.1.

The second option exercise

In Fig.5 shows a view in plan, illustrating the main part of the head, throwing the liquid, according to the second variant implementation of the invention. In Fig.6 shows a view in section, taken along the line 6-6 shown in Fig.5. Constituent elements similar to the constituent elements of the head, throwing the liquid according to the above variant implementation, denoted by the same reference position, as used previously, and their detailed descriptions are omitted. View in plan, according to Fig.5 illustrates a state in which the plate 3 with the holes depicted in Fig.6, is removed.

In this embodiment, the height mh of the camera 5 fluid pressure chamber R), is formed between the substrate 2 and the plate 3 to open the s, smaller than the aperture of the D-emitting holes 7 and the nozzle filter 8 is not provided. The height mh of the camera 5 fluid pressure chamber R) is smaller than the aperture of the D-emitting holes 7, and therefore, the foreign substance particles which are larger than throwing out the hole 7, misses the chamber 5 of the liquid and prevents the ingress of foreign matter into the pressure chamber R. Although in the cylinder, expelling the liquid, according to this variant implementation, the height mh of the pressure chamber R is less than the height of the pressure chamber according to the first variant implementation, the nozzle filter 8 is not provided. Therefore, the flow resistance of the ink becomes higher in comparison with the first embodiment, and the ink can be disposed with high frequency in the same manner as in the first embodiment.

A third option exercise

In Fig.7 shows a view in plan, illustrating the main part of the head, throwing the liquid according to the third variant of implementation of the present invention. In Fig.8 shows a view in section, taken along the line 8-8 shown in Fig.7. In the following text elements, similar constituent elements of the head, throwing the liquid according to the first variant implementation, denoted by the same reference position as the use is developed earlier, and their detailed descriptions are omitted. View in plan of Fig.7 illustrates the state in which the plate 3 with the holes depicted in Fig.8, is removed.

In the cylinder, expelling the liquid, according to this variant implementation in the chamber 5 of the liquid is provided by a pair of walls 9 of the flow channel. A pair of walls 9 of the flow channel enters between the pressure chamber R on the outside of the feed holes 2A in the X direction, and supports the plate with 3 holes. Each wall 9 of the flow channel runs essentially parallel to the direction Y matrices nozzles. The gap G between the walls 9 of the flow channel in the X direction is approximately Wx+100 μm or less, where Wx is the width of the feed holes 2A in the X direction (see Fig.7). Wall 9 of the flow channel are located outside of the feed holes 2A, and therefore can reduce cross-interference, not preventing the refilling of the pressure chamber R through the feed hole 2A. In the same way as in the above described embodiments implemented, it is possible to reduce cross-interference between the pressure chambers R while maintaining high-frequency ejection of ink. In addition, you can increase the strength of the plate with 3 holes.

In this embodiment, the wall 9 of the flow channel intermittently goes in the direction of the Y matrix of nozzles. However, sales is when the wall 9 of the flow channel is embedded throughout the matrix of nozzles, get similar effects.

The fourth option exercise

In Fig.9A, 9B and 9C shows in plan, illustrating the main part of the head, throwing the liquid according to the fourth variant of implementation of the present invention. Constituent elements similar to the constituent elements of the head, throwing the liquid according to the above-mentioned variants of implementation indicated by the same reference position, as used previously, and their detailed descriptions are omitted.

In the cylinder, expelling the fluid, is illustrated in Fig. 9A, the wiring 10 passes from the site, not in the center of the power-generating element 6, and the wiring 10 is changed alternately in the Y-direction matrix nozzles. Feed holes 2A are T-shaped and located so that their directions are changed to reverse in alternate order in the Y-direction matrix nozzles, adapting to the wiring diagram 10.

In the cylinder, expelling the fluid, is illustrated in Fig.9B, the wiring 10 passes from the site, not in the center of the power-generating element 6, and the wiring 10 are the same. Feed holes 2A, adapted to the wiring diagram, have the shape in which both ends in the X direction are in mutually opposite directions in the Y-direction matrix Zopa is.

In the cylinder, expelling the fluid, is illustrated in Fig.9C, posting 10 passes from the power-generating element 6 in the direction of the Y matrix of nozzles, and then bent in the direction X. the Feed holes 2A, adapted to the wiring diagram, have the shape in which the Central area is thinner than the Central section of the feed holes 2A, illustrated in Fig.9B.

Head, expelling the fluid, is illustrated in Fig.9A-9C, does not have a nozzle filter 8. However, even if the heads that release liquid, have a nozzle filter 8, then we obtain the same effects.

The fifth option exercise

In Fig.10A, 10B and 10C shows in plan, illustrating the main part of the head, throwing the liquid according to the fifth variant of implementation of the present invention. Constituent elements similar to the constituent elements of the head, throwing the liquid according to the above-mentioned variants of implementation indicated by the same reference position, as used previously, and their detailed descriptions are omitted.

In heads that release liquid, illustrated in Fig.10A and 10B, the input hole 2A formed in the shape of a comb, continuously surrounds three sides of each of the power-generating element 6. In the cylinder, expelling the liquid, proillyustriroval is authorized in Fig.10C, one feed hole 2A continuously surrounds three sides of each of the power-generating element 6 and intermittently surrounds the remaining one side. In heads that release liquid, illustrated in Fig.10A-10C, posting 10 (not shown) passes from the area surrounded by the opening 2A for the transaction, the circumferential surface of each of the power-generating element 6.

In heads that release liquid, illustrated in Fig.10A-10C, the area in the plane of the cutting opening 2A is larger than this size in other embodiments, implementation, and therefore the flow resistance of the ink is less. Thus, the frequency of ejection of ink can be increased through increased recharge rates.

Head, expelling the fluid, is illustrated in Fig.10A-10C, does not have a nozzle filter 8. However, even if the heads that release liquid, have a nozzle filter 8, then we obtain the same effects.

The sixth option exercise

In Fig.11A and 11B shows in plan, illustrating the main part of the head, throwing the liquid, according to the sixth variant of implementation of the present invention. Constituent elements similar to the constituent elements of the head, throwing the liquid according to the above-mentioned variants of implementation indicated by the same reference position as potrebscine earlier, and their detailed descriptions are omitted.

In heads that release liquid, illustrated in Fig.11A and 11B, the four sides of one of the power-generating element 6 is intermittently surrounded by four feed holes 2A. This increases the plots, which can be post 10, and increases the degree of freedom of wiring compared with other options implementation.

Although in the above embodiments, the implementation of the power generating element 6 is an electrothermal converting element (heater), power generating element 6 may be a piezoelectric element. In particular, when the power generating element 6 is a thin-film resistive element, it is possible to realize high-speed agitation, close to the high-speed initiation of the electrothermal converting element.

In addition, although in the above embodiments, the implementation of the emitted substance is ink emitted by the substance may be other liquid. In particular, the emissions of substances used for industrial purposes, have a higher viscosity than the ink for inkjet printing, in most cases, and the frequency of their recruitment tends to decrease. Thus, the problem of low frequency of replenishment for such a high-viscosity liquid can be solved by OSU head, throwing liquid, according to this invention.

In addition, the cylinder, expelling the liquid, according to this invention needs only to configure the following way. In the Y-direction matrix nozzles have several pressure chambers R, which serves ink through the feed holes 2A, and each pressure chamber R ejects ink, which this pressure chamber R is filled, from the release holes 7 through the use of the power-generating element 6. Thus, the invention may find wide application for heads that release liquid and having such a configuration. For example, this invention is applicable to a recording head used in the cylinder, expelling the fluid and related to the so-called Palestrina type, and also to a recording head used in the recording device, releasing the fluid related to the type of serial scan described above.

Although this invention is described with reference to possible embodiments of, it should be understood that the invention is not limited to the disclosed among the possible ways of implementation.
