The technical field to which the invention relates.

The present invention relates to head to eject the liquid, for example the print head to eject ink to jet the printer, and, in particular, to the configuration of the channels through which the liquid is supplied in a separate chamber, where the elements of the formation energy of ejection, as well as to the conductors used to excite the elements.

The level of technology

In the known printhead heaters, acting as elements of the formation energy, are placed on the substrate in the two matrices. One supply port is formed between matrices heaters so that it penetrates through the substrate. Thus, the ink serves, through the supply port, a pressure chamber in which are located respective heaters.

Figa is a view in perspective in partial section showing the main part of a conventional printhead. FIGU is a form that is similar figa, but on which the jet plate 502, shown in figa, is omitted. As shown in figa, the substrate 503 contains many heaters 509, excitatory circuits 509b for excitation heaters 509 and logic circuits 509c made with the ability to control the exciting schemes for including the Deposit or disable push. In addition, the jet plate 502 is located on top of the substrate 503 to form holes 506 to eject, Plenum 508 (pigv) and channels 507 (pigv), which correspond to the individual heaters 509. Thus, two matrices heaters (matrix of pressure chambers and channels) are provided on the substrate, and port 505 ink is formed as a hole located between matrices heaters and passing along matrices heaters and through the substrate. Thus, the ink supplied from the reservoir with ink port 505 submission, served in separate channels 507 and the pressure chamber 508, placed on both sides of the supply port, in conjunction with the operation of the ejection of ink.

Figure 2 is a top view showing a substrate on which is provided six modules matrices heaters (and holes to eject); one module matrices heaters shown on figa and 1B. One module of the matrix corresponds to one type of ink. Thus, figure 2 shows a basic configuration of a printhead made with the possibility to push six types of ink, such as cyan, Magenta, yellow, light blue and purple flowers, with lower concentrations of pigments, as well as black color. As shown in figure 2, two electrodes 510 power supply feature that is, what port 505 submission is placed between the electrodes 510, while the matrix heaters are placed on both sides of the port 505 submission. I.e. each of the two electrodes 510 power supply, which is designed with the ability to accept external power through the electrodes 511, provides power to initiate matrix heaters on the side that is the same side of the electrode power supply relative to the port 505 submission. In addition, exciting scheme 509b stimulates matrix heaters on the side of the identical side of the driving circuit 509b regarding port 505 submission.

Figa is a top view showing an example of the configuration of the above-described printhead, in particular, holes for pushing (heater), pressure chambers and channels. FIGU is a view in cross section along the line IIIB-IIIB in figa. In addition, figs is a top view of the configuration shown in figa, to which is added excitatory circuits, conductors and power the heaters. Fig.3D is integrated view of the field on pigs, which is shown by dotted lines. In the printhead is performed as shown in these drawings, a portion of the space formed between the substrate 503 and allow plate 502 acts as a common chamber 504 for liquids. Port 505 fluid supply is connected with a common chamber 504 for jdcostino, separate channels 507 are connected to a common chamber 504 for liquids. Pressure chamber 508 is formed at the end of each of the channels 507, which is the total opposite chamber 504 for liquids. Each of the holes 506 to eject formed to allow the plate 502 so that it connects with the corresponding pressure chamber 508. Heater 509 is in position in the pressure chamber, which corresponds to the hole 506 to eject. Ink, served in a communal cell 504 for fluid through the port 505 of the fluid, served in the pressure chamber 508 through the appropriate channels 507. In each of the pressure chambers 508, the heater 509 delivers thermal energy to the ink. Based on the supply of thermal energy, the ink pushed out through the opening 506 to eject.

As shown in figs and 3D, for each of the matrices heaters on both sides of the port 505 of the feed conductor 510A model power/heater connecting conductor 510 power supply and the heater 509, and the conductor 510b heater/exciting circuit connecting the heater 509 and exciting scheme 509b, are provided for each heater.

Figa-4D are views showing another conventional example of the printhead described in PTL1. This printhead is different from the printhead shown in figa-3D, the fact that it has an increased density komponovki the holes for the push. More specifically, the holes for pushing (and the corresponding heaters, pressure chambers and the like) are arranged with a shift and thereby firmly placed. This has the advantage of being possible to prevent the increase of the size of the printhead, in particular, of the substrate, thereby reducing the cost of manufacturing the printhead.

As shown in figa-4D, the substrate 503, two matrices, each of which contains many modules, each of which includes a heater 509, the pressure chamber channel 508 and 507, are provided on respective both sides of the port 505 submission. The modules in each of the two matrices are alternately placed at a considerable distance and short distance from the port 505 submission. Thus, compared with the configuration in which the same number of modules are simply placed in line along the longitudinal direction of the port 505 submission, the configuration shown in figa-4D, it is possible to increase the density of the layout. This provides an increase in the number of modules arranged on a substrate identical size. In this case, the magnitude of the driving circuit 509 and logic circuits (not shown in the drawings) shall be increased by the value corresponding to the increased number of holes to eject. However, the area occupied by the circuits can be reduced compared with the square is the area in case if you feature two matrices, each of which includes a supply port, heaters, excitatory circuits and logic circuits (not shown in the drawings), as shown in figure 3. I.e. the size of the layout required for the two ports of the feed in a separate module arrangement, can be reduced almost by half, thereby providing a reduction of the area of the substrate. In addition, compared with the configuration in which the modules are simply inserted along the longitudinal direction of the port 505 of the feed composition with a shift of modules that includes holes for ejection, provides sufficient thickness for each partition 512, intended to separate the channels. This prevents reduction of the reliability of the printhead.

In the above configuration of the holes to eject (heater), pressure chambers and channels, each wire 510A model power/heater and the conductor 510b heater/exciting scheme has two types of the length of the layout.

The invention

Technical problem

As described above, the layout with offset holes to eject it is possible to increase the density of the layout of the modules, which includes holes for ejection. However, in the beam layout with shift, in the matrix of holes 506a to push closer to port 505 feed, channel 507b for Plenum 508b, which is far from the port 505 submission, is located between the pressure chamber 508a for holes 506a for removing and connecting the pressure chamber 508a for connecting hole 506a to eject. Thus, the volume and the area near the pressure chamber 508a and holes 506a to eject limited, resulting in limited characteristics, for example, the estimated volume of the buoyancy. For example, as shown in figs and 4D, heaters and pressure chamber in which are located respective heaters, can be smaller in area than the heaters that are far from the port of submission.

On the contrary, the channel 507b for far Plenum 508b are formed between neighboring pressure chambers 508a. Thus, the provision of channel 507b with a large width is difficult. In addition, the length of the channel 507b should increase depending on the size of the pressure chamber 508b. Restrictions on the width and length of the channel often increase the time required to refill the ink after ejection through the far hole 506b to eject. Thus, the decrease of the ejection cycle (increased frequency pushing) becomes difficult.

The above-described various restrictions partly caused p is a layout tool, in which identical type of ink holes for pushing (and associated heaters and the like) are divided into two groups through a single port 505 submission. More specifically, the port 505 feeder is used for feeding ink to many holes to eject placed on both sides of the port 505 submission. Port 505 submission thereby passes a relatively large distance along the matrix of holes to eject and has a relatively large area, to enable feeding of a large volume of ink for a variety of holes to eject. As a result, in particular, the increase in density of the layout of the holes to push limits the installation location or area heaters, pressure chambers and channels. This leads to the above-described various limitations. In this case, in addition to the above pressure chambers and channels, layout guides, constructed on a substrate, can similarly be limited.

The purpose of the present invention is to provide a head to eject the liquid in which the pressure chambers, channels, etc. can be tightly placed on the substrate without the above restrictions, thereby providing the possibility of increasing the frequency of replenishment, as well as associated inkjet printing device.

The decision problem is we

In the first aspect of the present invention provides a head to eject the liquid, comprising: multiple supply ports through which the identical kind of liquid is supplied to the pressure chambers, each of which connects with an opening for the ejection and each of which is an element formation energy push part of the jumper is made with the possibility to separate the multiple supply ports from each other; and a conductor provided in part of the saddle, and the conductor is used for the excitation of the element formation energy push.

In the second aspect of the present invention provides a head to eject the liquid, comprising: a lot of pressure chambers provided correspondingly to many holes to eject liquid, and a lot of pressure chambers include elements of the formation energy for the formation of the energy used to eject liquid; and a substrate containing the matrix port of the feed, which is ordered multiple supply ports, each of which is formed as a hole passing through the substrate, and is configured to apply the liquid in the pressure chamber, and the matrix elements of the formation energy, which connects to the matrix port of the feed and which is ordered sets the elements of the formation energy, while the conductors used for the excitation of the elements of the formation energy, are formed in parts of the jumpers, each of which is formed between many ports submission to the matrix port of the feed.

In the third aspect of the present invention provides an inkjet printing device that performs printing by using the printhead to eject ink when the printhead contains: multiple supply ports through which the identical type of ink is supplied to the pressure chambers, each of which connects with an opening for the ejection and each of which is an element formation energy push part of the jumper is made with the possibility to separate the multiple supply ports from each other; and a conductor provided in part of the saddle, and the conductor is used for the excitation of the element formation energy push.

Advantages of the invention

According to the above configuration, in the head to eject the liquid, a pressure chamber, channel, etc. can be tightly placed on the substrate, as well as increased frequency of replenishment. In addition, for example, the conductors used to excite the elements of the formation energy of ejection can be placed in parts of the jumpers, acting as the dividing partitions on the I port of the feed. This provides an opportunity to shape the scheme of conductors through effective use of layout multiple ports filing.

In addition, Fig.7 is a view showing the appearance of the printhead. The frame 110 of the inkjet printing device according to the present variant implementation contains a number plate of metal elements with a predetermined rigidity. The frame 110 forms a frame structure of an inkjet printing device. The frame 110 includes section 111 of the feed carrier made with the possibility to submit the print medium in the form of sheets (not shown in the drawings) in the print section, and section 113 of the transportation carrier, made with the ability to send a print medium fed from section 111 of the filing of the medium in the desired position for printing, and from the position for printing in section 112 of the issuing carrier. The frame 111 additionally includes a printing section configured to perform a predefined operation p the parts on the print medium, transported into position for printing, and section 114 of the recovery head is made with the possibility to perform the recovery process to the print section.

The print section includes the carriage 116 supported so that it moves along the carriage shaft 115 for scanning, and the cartridge 118 head mounted in the carriage 116 so that it can be removed by operation of the lever 117 installation head.

The carriage 116 is installed in the cartridge head 118 includes a cover 120 of the cradle is configured to allow placement of the print head 119 in the cartridge 118 head in a predetermined position for mounting on the carriage 116. In addition, the carriage 116 includes a lever 117 installation heads made with the possibility to engage with the holder 121 of the reservoir of the print head 119 to clamp and position the print head 119 in a predetermined position for installation.

One end of a contact flexible print cable (hereinafter also referred to as the contact FPC) 122 is connected with the other part of the carriage 116, performed with the opportunity to engage with the print head 119. The contact part (not shown in the drawings)formed on the end of the contact FPC 122 electrically contact with the contact part 123 provided in the print head 19. This enables transmission of various pieces of information for printing, supply power to the print head 119, etc.

The cartridge 118 head according to the resubmitted version of the implementation includes a reservoir 124 ink stored in the ink, and the print head 119 which has a capability to eject ink supplied from the reservoir 124 ink through holes for ejection in accordance with print data. The print head 119 contains a matrix of heaters corresponding to the holes and push the wires for the heaters; heaters and conductors provided on the substrate. The print head 119 is of the type of cartridge where the print head 119 is installed in the carriage 116 with the possibility of retrieval.

In addition, this version of the implementation allows the use of six independent tanks 124 ink for black (Bk), light cyan (c), light red (m), cyan (C), Magenta (M) and yellow (Y) colors for the device to provide photographic quality color printing. Each of the reservoirs 124 ink includes an elastically deformable lever 126 to extract, which can separitist on the cartridge head 118. The operation of the lever 125 to extract provides the ability to extract p is servoir 124 ink from the print head 119, as shown in Fig.7.

The first option exercise

Printhead according to the first variant implementation of the present invention relates to a configuration in which multiple ink supply ports are provided for each of the Bk, c, m, C, M and Y ink. Two heaters and two pressure chambers are provided in Association with each of the supply ports.

Figa is a view in perspective showing the substrate 2, on which are formed of jet plate 3, in which are formed holes 7 to eject, excitatory circuit 9b for excitation of the heaters 9 and logic circuits 9c to select the appropriate excitatory circuits, and these elements form a printhead according to the present variant implementation. The configuration shown in figa, is provided for each of the Bk, c, m, C, M and Y ink. Ie, as shown in figure 2, the configuration applies to one of the six modules matrices heaters (and holes to eject), and these modules correspond to the appropriate color ink. FIGU is a view in perspective showing the inner part of the printhead down the top part to allow the plate 3, shown in figa. Figv shows the structure made with the possibility to introduce the ink from the supply port 24 to the pressure chamber 14 through the channel 17. As shown in the drawings, the spoon 2 and jet plate 3 are combined, in order to form the channels 7 and the pressure chamber 14, which are connected with the respective ports 24 of the ink supply in part of the space between the substrate 2 and to allow the plate 3.

Figa is a top view showing the layout of holes for ejection, pressure chambers, channels and ports of the ink in the printhead shown in figa and 8B. FIGU is a view in cross section along the line IXB-IXB in figa. Holes 7 to eject shown by circles on figa, in fact, are formed to allow the plate 3, and not on the substrate 2. However, the holes 7 to eject shown to illustrate the mutual location of the pressure chambers, etc. This also applies to other drawings described below. In addition, figs is a top view showing a layout in which excitatory circuits, the conductors of the power supply and the heaters are added to the layout shown on figa. Fig.9D is the integrated form of the composition area on pigs, which is shown by the dotted line.

As shown in figa and 9B, the print head according to the present variant implementation includes many ports 24 of the ink supply. Many ports 24 submission form two matrices ports feed. Connecting ports 24 filing in each of the matrices are separated from each other by parts 20 plumage is of ICEC. In addition, the pressure chambers 14 are provided on respective both sides of each of the ports 24 of the feed. So, basically, the ink is fed from a single supply port 24 to the pressure chamber 14 located on respective both sides of the supply port 24, i.e. only two of the pressure chambers 14. Each of the pressure chambers 14 includes a heater 9, acting as an element formation energy push. Hole 7 to eject is in position to allow the plate which corresponds to the heater. Many ports 24 of the feeder is formed so that they penetrate through the substrate 2 in the thickness direction. Ports 24 supply is not connected, at least in the substrate 2 to each other and run as an independent holes. Each of the ports 24 of the feeder is connected with a common chamber 5 for the liquid. In addition, the channels 7 are on respective both sides of the common chamber 5 to the liquid so that they are connected with a common chamber 5 for the liquid. Pressure chamber 14 is connected with an end of each of the channels 17, which is the total opposite chamber 5 for the liquid.

Matrix of holes 7 for the buoyancy is such that each of the ports 24 submission to the left of the two matrices holes 7 for pushing on the respective both sides of the supply port 24 are placed in the identical position in which upravlenii along the matrix ports filing as shown in figa. In addition, for each of the ports 24 of the feed in the right matrix ports feed holes 7 for pushing on the respective both sides of the supply port 24 are placed in identical positions in the above direction. Posted thus the matrix of holes for ejection, corresponding to the left and right matrices supply ports are shifted from each other by a half pitch layout of holes for ejection. Thus, the printhead according to the present variant implementation, the four matrix of holes to eject feature for the same color ink, and the print head performs scanning in the direction orthogonal to the direction along a matrix of holes for ejection. Thus, since the two sets of matrices holes for ejection are shifted from each other by half a step, the print resolution in the direction orthogonal to the scanning direction may be set so that it is twice the step layout of holes for ejection. In addition, for example, ink can be pushed in the same pixel through the holes to eject located in identical positions in the direction of the layout of holes for ejection so that the point of the pixel can be formed of two drops of ink. Alternatively, left, figa, and the two matrices of holes to eject, the respective left matrix ports supply, can be used for scanning in one direction, while the two matrices holes for ejection, corresponding to the right matrices ports supply, can be used to scan in the opposite direction.

On figs and 9D, each of the heaters 9 connects the conductor 10a power/heater connecting the heater 9 with the guide 10 power, and the conductor 10b heater/exciting circuit connecting the heater 9 to the driving circuit 11. For each of the ports 24 of the feed part of the conductor 10a power/heater and a conductor 10b heater/exciting circuit for the heater 9, located to the right of the supply port 24 provided in part 20 of the lintel below the supply port 24. Thus, the wires for the heater right hand placed using part 20 jumpers, which separates the ports 24 submission from each other.

As described above, according to this variant implementation, the multiple supply ports are provided, to supply the ink in the channels and pressure chambers, and are separated from each other by parts of the jumpers. Thus, the structure of the ejection, each of which includes a channel, a pressure chamber, a heater, an aperture for ejection, can be placed on the respective both side of the each port feed. Therefore, even if the structure of the ejection relatively densely placed, channel, pressure chamber, a heater, etc. can be a necessary and sufficient size and location without limitation, associated with the layout. In particular, the arrangement in the conventional example shown in figs, and layout in the present embodiment, shown in figs are identical to the area. As apparent from these drawings, is almost identical to the number of heaters can be placed in identical area, i.e. heaters can be placed in an identical density layout. In this case, compared with the latest technology, this version of the implementation provides many small ports of the feed, thereby providing the possibility of efficient use of channels, pressure chambers, heaters, etc. As a result, channels, Plenum heaters, etc. should now be sufficiently square, not Pets limitation each other through the pages of the channels, the pressure chambers, heaters, etc. may Thus be provided to the print head, which has the possibility of increasing the frequency of replenishment.

In addition, the conductors connecting the heater to a power source and connecting the heater with stimulating the scheme, can be placed without the above limitations associated with layout. The conductors are placed in parts of the jumpers, acting as cubicles for ports feed. This provides the possibility of forming a circuit conductors through effective use of layout multiple ports filing.

When heaters and vents for removing tightly placed, the magnitude of the driving circuit 9b and logic circuits 9c should accordingly be increased. However, the area occupied by circuits can be reduced compared with the area of the separate layout of matrices, each of which includes a supply port, heaters, excitatory circuits and logic circuits. More specifically, in comparison with a case in which two module layout is shown in figure 3, are provided so that the number of holes to eject the module layout is comparable to the number in one module layout is shown in figure 9, the arrangement according to the present variant implementation allows reducing the area of the substrate. Size of the layout required for the two ports of the feed in a separate layout of the two matrices can be reduced by half, thereby providing a reduction of the area of the substrate. In addition, the layout of the driving circuit and the logic is some schemes in the matrix gives the possibility of reducing the area of layout versus layout in which excitatory circuits and logic circuits are placed in different matrices. This is because an efficient layout can be obtained by placing components of the driving circuit and logic circuits in the matrix. Describes a specific example in which the MOS transistors are used as excitatory circuits. The drain electrode of each MOS transistor is connected with the potential of the power source through the heater. The source electrode of the MOS transistor is connected to ground potential. The drain electrodes of the MOS transistors must be independently allocated to the respective heaters. On the other hand, the source electrode may be shared by adjacent MOS transistors. Sharing the source electrode through the adjacent MOSFETs provides a reduction of the area of the layout compared to the separate arrangement of the electrodes of the source. Additionally, when the feature logic circuit, the source electrode may be shared by adjacent logic circuits or conductors of the power can be shared, to supply potential of the power source in the logical schema. Thus, this arrangement provides the possibility of preventing increase in size of the substrate in comparison with the components is vcoi logic circuits in various matrices.

The second option exercise

The second variant implementation of the present invention relates to a layout in which one matrix ports supply is additionally located in the Central part between the two matrices ports supply, shown in figure 9, so that each pressure chamber adjacent to the Central matrix port to supply ink serves as adjacent supply port in the Central matrix port of the feed, and from the opposite adjacent supply port in one of the original two matrices ports filing.

Figa is a top view showing the layout of holes for ejection, pressure chambers, channels and ports feed into the printhead according to the second variant of implementation of the present invention. FIGU is a view in cross section along the line XB-XB in Fig. 10A. In addition, figs is a top view of the configuration in which the excitatory circuit, the conductors of the power supply and the heaters are added to the configuration shown in figa. Fig.10D is the integrated form of a partial area of the configuration shown in figs.

In the above-described first embodiment, four matrix of holes for ejection are two matrices port support. On the other hand, four of the matrix of holes for ejection are for the three matrices port support. In addition, in vnutrennikh of the four matrices holes for ejection, pressure chamber 14 corresponding to each hole 7 to eject, connected with two channels 17, posted on the respective both sides of the pressure chambers 14. I.e. in each hole to push in the inner two matrices of holes to eject the ink is fed from the opposite adjacent ports flow through the appropriate channels 17.

In the present embodiment, the pressure chamber 14 and the opposite channels 17 are symmetrical shape. This gives the possibility of improving the ejection characteristics of the two Central matrix of holes to eject. More specifically, the heaters 9 are placed opposite each of the openings 7 to eject two matrices holes for ejection under this option implementation. Adjacent and opposite the ports 24 of the feeder is formed so that the distance from the edge of each of the ports 24 of the ink to the edge of the hole 7 to eject nearest to the port 24 of the ink is the same between the ports 24 of the feed. I.e. routes flowing fluid from the hole 7 to the respective ejection ports 24 filing symmetrically formed relative to the holes 7 to eject.

Printhead according to the above-described second variant implementation can not only provide benefits identical to the benefits which the EU ETS the above-described first variant implementation, but also to form the following specific benefits.

The layout of the ports 24 of the feeder allows the ink supply through two channels 17, posted on the respective both sides of each pressure chamber 14, and allows symmetric extension and contacting bubbles formed as a result of heat by the heater 7, a relatively holes for ejection. In particular, when the heaters 9 are included, electricity is converted into heat to enable the heaters 9 to generate heat. Thus, in the pressure chamber 14, which is provided by the heater 9, the ink is placed above the heater 9, the exposed film boiling, thereby forming a bubble. When bubbles are formed in the pressure chamber 14, pressure is applied to push the ink in the direction of the hole 7 to eject, to be placed above the heater 9. The ink is then pushed through the hole to eject. In combination with popping, served ink in the pressure chamber 14 through the port 24 flows through the common chamber 5 for the liquid. Here, the supply port 24, through which ink is served in the pressure chamber 14 through the common chamber 5 for the liquid is provided on each of both sides of the hole 7 to eject. Therefore, in the hole 7 to eject the Ernie served through the ports 24 of the feed, posted on respective both sides of the hole 7 for pushing in the pressure chamber 14. This allows the ink supply hole 7 to eject balanced instead of restricting the flow of ink supplied into the hole 7 to eject, one direction. In addition, in the present embodiment, each of the ports 24 of the feeder is formed so that the distance from the edge of the supply port 24 to the edge of the hole 7 to eject (the lower part of the pressure chamber, in which the hole 7 to eject projected)nearest to the port 24 of the ink is almost the same between adjacent ports 24 filing. In addition, for each hole 7 to eject, the channels in the ports 24 of the feed are symmetric with respect to the holes 7 to eject.

In the above configuration, mainly because the ink is served in the hole 7 for pushing through the TV mounted on the respective both sides of the hole 7 to eject the frequency of replenishment for holes to eject may increase.

In addition, since the bubbles can expand and contract symmetrically with respect to the holes 7 to eject, ejection can stably be maintained in the same direction. I.e. conditions such as loss of feed from the supply port 24 to the pressure chamber 14, I which are identical for all holes to eject. Thus, conditions such as flow rate and the flow rate of ink supplied into the hole 7 to eject during ejection, and the flow resistance of the ink is pushed back when the bubble expands, are practically the same for the holes to eject, avoiding the limitation of the expansion of a bubble in a certain direction. Do not allow the limitation of the compression of a bubble in a certain direction, and he balanced is directed toward the center of the heater 9. As a result, mark pushed the ink is thick and straight, providing the opportunity to increase the size of the satellites in the separation of a trace. Thus, the satellites are also distributed along the direction of ejection. In this case, many of the satellites are distributed in an identical direction. Thus, the satellites are combined into an even larger satellite. In addition, the main part of the drops also extends along the direction of ejection.

As described above, the increased size of the satellites makes it unlikely that the effect on the position of the collision of satellites by means of air flow. No Pets varying density even during high speed printing or printing with small drops. This, in turn, makes it unlikely that the occurrence of density inhomogeneity in the image is the situation. In addition, the increased size of satellites increases the speed at which the satellite successfully reaches the print medium. As a result, the volume of ink dust, extending between the printhead and the print medium is reduced.

A third option exercise

Third alternative implementation of the present invention corresponds to the arrangement in which the matrix of supply ports provided outside and adjacent to the other extreme external matrix of holes for ejection in the layout matrix ports filing, etc. according to the above-described second variant implementation.

Figa-11D are views similar to figa-10D illustrate a second variant implementation. In particular, as shown in figa, matrix ports 24 submission are provided on respective both lateral sides of the set of four matrices of holes 7 to eject. This leads to the structure of the channel, symmetric with respect to the nozzles to eject.

Because the channels are symmetric with respect to the nozzles to eject, as described above, the frequency of replenishment is supposed to rise for the entire printhead. In addition, satellites can be reduced by reducing the above-described cross section of the channel.

The fourth option exercise

The fourth is the first variant implementation of the present invention corresponds to the layout of the ports filing, etc. according to the above third variant of implementation, in which the conductor 10a power/heater is shared by the two heaters 9.

Figa-12D are views similar to figa-11D illustrate a third option implementation. In particular, as shown in fig.12D, conductor 10a power/heater is shared by heaters 9, corresponding to the two holes to eject placed in the transverse direction in figa and belonging to the first and second of the four matrices of holes to eject to the left of them. Conductor 10a power/heater is also shared by heaters 9, corresponding to the two holes to eject placed in the transverse direction in figa and belonging to the third and fourth of the four matrices of holes to eject to the left of them.

Thus, sharing of the conductor provides a reduction in the width of the space part 20 of the lintel, which is a conductor. As a result, if the conductor is provided in part 20 of the lintel, the degree of freedom when designing the width of the part of the saddle increases. For example, the width of the part of the jumper can be minimized to reduce the size of the substrate.

The fifth option exercise

The fifth option domestic the present invention corresponds to the layout of the ports filing, etc. according to the above fourth variant implementation, in which the conductors for the heater are provided in multiple layers.

Figa-13D are views similar to figa-12D illustrate a fourth option implementation. In particular, as shown in fig.13D, conductor 10a power/heater is provided on the upper level of the substrate, as in the case of the above embodiments. On the contrary, for the two heaters provided on respective both sides of the supply port 24, the conductor 10c heater/exciting circuit connecting the heater 9, far from the exciting circuit 9b, exciting scheme 9b, is provided in the substrate. Conductor 10b heater/exciting circuit connecting the middle heater 9 exciting scheme 9b, is provided on the upper level of the substrate, as in the case of the above embodiments. I.e. in the present embodiment, the conductor connecting the guide 10 power heater 9, and (part) of the conductor connecting the heater 9 to the driving circuit 9b made with the possibility to form multiple layers in the substrate. In other words, the conductor 10a power/heater etc. need not be located on the upper level of the substrate, but at least two types of conductors can be made with the possibility of formation shall be several layers.

In the present embodiment, to allow placement of the conductors so that they form several layers, the conductor 10c heater/exciting circuit and a through hole 11 are provided around the far heater 9; conductor 10c heater/exciting circuit is provided in the substrate, and a through hole 11 is electrically connected with the conductor of the heater 9. Partition 12 is provided above the position on the substrate in which is formed a through hole 11. Thus, relatively steep step portion on the substrate due to the formation of through holes can be covered by a dividing partition. Therefore, it is possible openness stepped portion for exposure of the ink can be excluded. I.e. this steep part often has a surface protective film with inferior pokryvailo and presumably cannot ensure long-term reliability, if it is open to the influence of ink. To prevent this, an additional manufacturing process, for example, additional smoothing process to prevent the formation of steep parts or coatings with a more stable protective film. This increases costs. However, the configuration shown in the present embodiment, network enabled the industry to prevent such negative effects.

Similarly to the fourth variant implementation, the above-described fifth variant implementation provides a reduction in the width of the space part 20 of the lintel, which is a conductor. As a result, if the conductor is provided in part 20 of the lintel, the degree of freedom when designing the width of the part of the saddle increases. For example, the width of the part of the jumper can be minimized to reduce the size of the substrate.

The sixth option exercise

Sixth variant of implementation of the present invention corresponds to the configuration in which the conductors for the heater are provided in multiple layers, as in the above fifth embodiment, and in which a through hole through which the conductors are connected, is formed in each part of the jumper is made with the possibility to separate ports of filing in the Central matrix port feed from each other, in this case, the jumper is covered with a wall covering.

Figa-14D are views similar to figa-13D illustrate a fifth variant implementation. As shown in fig.14D, a through hole 11, through which the conductor 10c heater/exciting circuit provided in the substrate, and the conductor of the heater 9 is electrically connected, is provided in each part of the saddle, made with the ability to separate on who you 24 filing in the Central of the five matrices ports filing (figa) from each other. Covering wall 13 is formed in part of the jumper so that it covers the through hole 11. This configuration gives the possibility of providing advantages similar to the advantages described above fifth variant of the implementation, and, in particular, makes it possible to determine the location and size of the heater, etc. without influence by forming through holes. For example, relatively large heaters and pressure chambers can be provided.

The seventh option exercise

Seventh variant of implementation of the present invention corresponds to the arrangement of the heaters and the like according to the above fifth variant implementation, in which on each side of the pressure chambers is provided with one port of delivery, which corresponds to two pressure chambers.

Figa-15D are views similar to figa-13D illustrate a fifth variant implementation. In the present embodiment, in particular, one port 24 of the feed corresponds to two pressure chambers 14 (and the hole 7 to eject)provided on each of both sides of the supply port 24, so that the two pressure chambers, the ink fed through the supply port.

In addition, if each port of the supply is shared through the pressure chambers, as described above, in some partition walls plenarnih cameras, path Explorer is blocked through the supply port 24 to prevent the placement of the conductor. Thus, in particular, as shown in figs and 15D, the conductor is provided in each of the second part 20 of the lintel and the wires for the two heaters are provided in one part 20 of the lintel.

The above-described seventh variant of the implementation not only provides the advantages of the above-described fifth variant of the implementation, but also provides the capability of providing a relatively large supply ports. Thus, the performance of the ink can be increased. It should be noted that, although the above-described variant of the implementation shows an example of providing guides for the two heaters in one part of the jumper, the number of heaters is not limited to two. Conductors for more than two heaters may be provided in one part of the jumper, and thus the required size of supply port may be provided.

The eighth option exercise

Eighth variant of implementation of the present invention corresponds to the arrangement of the heaters and the like according to the above sixth variant implementation, in which each supply port is provided in Association with two pressure chambers.

Figa-16D are views similar to figa-14D illustrate a sixth option on the westline. In the present embodiment, in particular, as shown in figa, one port 24 of the feed corresponds to two pressure chambers 14 (and the hole 7 to eject)provided on each of both sides of the supply port 24, so that the two pressure chambers, the ink fed through the supply port. In addition, when each port filing jointly used with the pressure chambers, as described above, in some partition walls for pressure chambers, the path Explorer is blocked through the supply port 24 to prevent the placement of the conductor. Thus, in particular, as shown in figs and 16D, the conductor is provided in each of the second part 20 of the lintel and the wires for the two heaters are provided in one part of 20 jumpers. Therefore, two sets of through holes 11 corresponding to the two heaters 9 are formed in the identical part of the jumper to the corresponding supply port in the Central matrix port of the feed.

The above-described eighth variant of the implementation not only provides the advantages of the above-described sixth variant implementation, but also provides the capability of providing a relatively large supply ports. Thus, the performance of the ink may be increased.

As shown in Fig, hole 7A to eject the external is atrice holes for ejection and the separation wall 12A in the Central matrix of holes for ejection are almost on a straight line. In addition, the hole 7B for popping in the external matrix of holes for ejection and the separation wall 12B of the Central matrix of holes for ejection are almost on a straight line. Then, each of the conductors may be provided below the heater corresponding to the outer hole to eject. I.e. conductors are provided along respective paths, shown by lines 15A and 15B with the alternate long and short dash, with a part of each conductor is located below the heater. This provides an increase in the degree of freedom of the position and size of the heater.
