The technical field to which the invention relates

The present invention relates to a recording head, releasing liquid such as ink.

Description of the prior art

Inkjet recording device using the contactless scheme records and differ in that they can record data on various recording media and high speed, and little noise during recording. Thus, such an inkjet recording device have been widely used as such a recording mechanisms, such as a printer, a word processor, Fax and copy machine.

Such an inkjet recording device using the methods of ejection of ink, including a typical way in which heaters are used as recording elements. In a typical method uses an inkjet recording head (hereinafter also referred to as recording head), which has a recording liquid chamber with a heater, and in which electric pulses are applied to the heaters as signals recording. Further, the heaters generate energy emission (thermal energy), which is supplied to the recording liquid to cause it phase transition. During the phase transition of the writing fluid bubbles (boiling), so that the pressure generated by bubbles of use which is to eject droplets of writing fluid.

In Japanese laid patent application No. 2002-19146 discussed example of such a recording head. On Fig shows a diagram in perspective illustrating the recording head.

The recording head 1 on Fig has a substrate 2, and 3 of the recording elements, each of which has many recording elements arranged on it. All recording elements provided with ejection ports to eject ink. Logical signals and the supply voltage are supplied to the substrates 2 and 3, the recording elements of the main unit of an inkjet recording device (hereinafter also referred to as the main unit of the recording device) through the substrate 5 electrical contacts and electrical element 4. As a result, the control circuit (logic circuit and the voltage conversion) in the substrates 2 and 3, the recording elements employed to actuate the predetermined recording elements within a predetermined period of time, resulting in the ink are ejected from the ejection ports corresponding to the recording elements.

Each of the logical signal includes synchronizing pulses as a reference for the operation of logic circuits, "write data" to determine the recording elements that must operate, "Zap the rising signal to temporarily store the recording data in the trigger locking scheme, which is one of the elements of the logic circuit, and the heat enable signal to determine a time interval for actuating the recording elements.

In recent years, to further increase the print speed was discussed recording head of full-length type, in which a large number of substrates of recording elements are arranged zigzag, and their width is greater than the width of the recordable media. On the recording head on Fig printing involves scanning a recordable medium, the recording head. In contrast, the recording head of the full-length type allows you to print at high speed through a single pass of the recording head, without scanning a recording head, which has led to the widespread use of recording devices of this type in business and industry.

For such recording heads, full-length type require a large number of substrates recording elements, as well as a large number of ejection ports to allow printing through one pass of the head without deterioration of image quality due to avibras ink. Accordingly, it requires the formation of a large number of terminals of the logical signals for input/output logic signals, and a large number of logical lines C the signals are conducted through the electrical element for forwarding logic signals. This structure may cause noise in the scheme logic signals.

For example, the parallel lines of the logical signals may affect each other, causing capacitance, which induces noise. As a rule, longer and more dense wiring causes capacitance and, consequently, in the recording heads of larger size, such as the head of the full-length type, more likely to lead to more noise.

In addition, the transaction logic signals located close to the wiring of the power supply, in which the flow of large currents may be affected by induced noise. In the recording head of the full-length type, having a higher number of ejection ports in comparison with a recording head of a smaller type, a greater number of recording elements simultaneously driven, and large currents flowing through the power wiring, which drives the recording elements, which leads to the excitation noise.

Logical signal susceptible to noise may cause malfunction of the logic circuits controlled by a logical signal, and, therefore, the recording elements may operate in an unexpected position and at unexpected times, which will lead to undesirable ejection of ink and poor print quality. In addition, high-sensitivity circuit for high frequency logical the ski signals are responsive to noise, and therefore, it is necessary to protect high frequency logic signals from noise.

To reduce the influence of noise wiring high frequency logic signals should be located not adjacent to other transactions high frequency logic signals and transactions of power, in which the flow of large currents. As described above, however, the recording head of the full-length type has a greater number of transactions of logic signals, not all transactions a high-frequency signal can be located in accordance with the wishes. Therefore, to reduce the influence of noise the space between the lines of the high-frequency signal must be increased, which increases the electrical element and, ultimately, the recording head.

The recording head includes a substrate, a recording element having a recording element and a logic circuit, configured to control actuation of the recording elements; and electrical element configured to provide a wiring layer that has a first group of multiple terminals and a second group of the multiple terminals, and a lot of lines with which gralow, made with the possibility of connection of the first group of terminals with the second terminal group; wherein a set of signal lines includes many lines of logic signals, including logical line of the power source, the logical grounding line, and at least first and second lines of logic signals, and in which the wiring layer structure lines connected to one of the logical wires of the power source or ground, is located along the first and second wires of the logical signals.

In the structure of the N heaters 13, N switching elements 503 and N circuits 515 choice of heater belonging to the same group, and such groups exist from 1 to M. the Main unit of the recording device delivers clock pulses (CLK) terminal 509. In synchronization with the synchronizing pulses of the recording data received serially at M bits inputted through the terminals 510 and serially stored in the shift register 506. Recording data of size M bits are held in trigger locking scheme 505 in accordance with the locking signal (LT)coming through the locking terminal 508. Recording the data is transferred to the decoder 504 together with the signals serially received from the trigger locking circuit 505. The decoder 504 and converts the data signals into N signals 518 selection unit, which is received by the group from 1 to M. Then, M recording signals 517 data from the heating circuits 516 and N signals 518 selection unit from the decoder 504 ORed in the matrix circuit 515 selection of the heater, so that M×N heaters 13 uniquely selected as desired. Selected heaters 13 receives current from the circuit 516 heater within a predetermined period of time in accordance with recording signals 517 data which is obtained by the AND operation to switch signals of heat (heat enable, HE) from Clem is s 511 inclusion of heat (HE) and signals from the trigger locking circuit 505, which leads to the actuation of the heaters 13. The term "logical signal" hereinafter refers to the combination of clock pulses (CLK), the recording data (DATA), the locking signal (LT) and heat enable signal (HE).

Figure 4 shows that the silicon substrate 11 additionally has: a terminal 503 power (VH) of the actuation of the recording element, the supply voltage (about 24-30 In), which is supplied to the heater 13, the speakers of the recording elements; VH wiring 540 power supply connecting the VH terminal 530 with heaters 13; GND (GNDH) terminal 531 of the recording element and the GNDH wiring 541, and a discharge current from the heater 13. The silicon substrate 11 additionally has: a circuit 513 generation voltage actuation (VHT buffer) as the power source for the circuit 507 conversion voltage; terminal 532 of the power source of the triggering device actuation (VHT), supply voltage (about 12-14) scheme 513 generating the control voltage (VHT buffer); terminal 533 power source logic (VDD), supply voltage (about 3-5) to activate the logic circuits; and a terminal 534 logic GND (VSS)associated with the terminal 533 power source logic (VDD).

In other words, the terminal 530 of the power of the recording element is a power terminal for actuation. Vysokovolt what I post 540 power is the power wire for actuation. GND (GNDH) terminal 531 of the recording element is a ground terminal for actuation. Posted 541 GNDH is the ground wire for actuation. Terminal 533 of the power supply (VDD) logic circuit is a terminal of a power source for logic. Logic GND (VSS) terminal 534 is a ground terminal for logic.

Each of the substrates 10 recording elements provided from 30 to 60 terminals 14 (15 to 30 terminals on each side), including from 6 to 20 terminals for logic signals.

Again referring to figures 1 and 2, we see that the bearing element 20 supports and fixes the substrate 10, the recording elements are made of aluminum (A1203) and its thickness is from 0.5 to 10 mm Bearing element 20 can be made of other materials, for example, having a linear coefficient of expansion close to the coefficient of linear expansion of the substrate 10 of the recording elements, and having a high rigidity. Examples of such materials include silicon (Si), aluminum nitride (AlN), Zirconia, silicon nitride (Si3N4), silicon carbide (SiC), molybdenum (Mo) and tungsten (W).

Bearing element 20 has ports 21 of the ink supply ports formed in areas corresponding to the ports 12 of the ink substrate 10 of the recording elements. The substrate 10 of the recording elements attached to the bearing element 20 in the exact progenies by using the first adhesive.

Electrical element 30 is used to enter and feed the electrical signals b supply voltage to the substrates 10 recording elements for ink ejection. Electrical element 30 has one or multiple layers of wiring. For example, the electrical element 30 may be a two-layer flexible circuit Board, is made on the basis of material having a wiring layer on each of its sides, the top layer is covered with a protective film.

Electrical element 30 has, as illustrated in figure 2, the holes 31, which are mounted substrate 10 of the recording elements. Electrical element 30 has an additional terminals (second terminals) 32, electrically connected with the corresponding terminals 14 of the substrate 10 of the recording elements, and terminal 33 for external connection (first terminal)electrically connected to the main unit of the recording device.

Electrical element 30 is from 160 to 480 terminals 32, comprising from 40 to 160 terminals of the logical signals for input/output logic signals. The General structure of the integrated wiring inside electrical element 30. The number of external terminals 33 of the connection is changed from 100 to 200.

Electrical element 30 is glued using a second adhesive surface is attached to the substrate 10 of the recording elements, the bearing member 20. There is a gap m is waiting for holes 31 and the substrate 10 of the recording elements, which is hermetically filled in the first molding mass. Terminals 32 electrical element 30 is electrically connected to the terminals 14 of the substrate 10, the recording elements through a wired connection using metal wires. The connection between the terminals 32 and 14 is hermetically closed by the second casting mass 70. Electrical element 30 is bent to fit the shape of the two sides of the bearing member 20, and is fixed with sides for an easy electrical connection to the main unit of the recording device.

The element 40 of the ink supply system supplies ink from the cartridge to the substrate 10 of the recording elements, it is made of, for example, by a method of injection molding using synthetic materials. The element 40 of the ink supply system includes a tank 41 for ink for ink supply to many substrates 10 of the recording elements. The tank 41 for ink has a hole 42 which is connected to the cartridge via a tube for supplying ink so that the ink flows into the reservoir 41. The element 40 of the ink attached to the supporting element 20.

The wiring topology of electrical element 30, which are characteristic of the present invention is described using the first example.

The wiring topology of electrical element 30, in accordance with the first example of its implementation is I, described in relation to Figure 5-9. Figure 5-8 shows a schematic perspective view illustrating the electrical element 30 from the front side electrical element 30.

Electrical element 30 has wiring layers on each side of the base material as the upper and lower layers. Figure 5 presents a simplified schematic diagram illustrating the topology of the wiring of the upper layer. Figure 6 presents a simplified schematic diagram illustrating the topology of the wiring of the lower layer. Figure 5 and 6 shows that the group Postings 34 logical signals separately connected to terminals 32 and the terminal 33 for external connection. Groups 35a and 35b logical wiring ground (VSS line) from the power source logic are connected to each other via a through hole. In other words, groups 35a and 35b consist of a posting ground for logic. Group 35b are connected to terminals 32, and the group 35a is connected to the external connection terminals 33. Group 36b and 36c consist of transactions for transfer of non-Boolean signals, which differ from the logical signals, the transaction includes, for example, the wiring of the power source of the recording elements, the wiring of the power supply device control actuation of the recording elements and the wiring of the power source logical schema. Wiring for transmission illogical signals connected to terminals of the mi 32 and the external connection terminals 33.

Figure 7 presents an increased circuit area B of figure 5, detail illustrating the wiring topology near the terminals 32. On Fig presents an enlarged diagram of the region C in Figure 5, detail illustrating the wiring topology near the terminals 33 for external connection. 7 and 8 shows that the electrical element 30 has a material 37 of the base and the protective layer 38 transactions with a boundary 38a. Terminal 32 and the terminal 33 for external connection receive signals, as illustrated in Fig.7 and 8, and all are in contact with air. Terminals terminals 32A and 32B are connected to terminals 33 for external connection with the use of lines 36b (Figure 5) and 36c (6) signals to actuate, respectively.

CLK line (wiring clock) 34E to transmit CLK and DATA lines (post recording data) 34F to transmit DATA intended for operation at a relatively high frequency of several MHz. In the present exemplary embodiment, as illustrated in Fig.7 and 8, CLK lines 34E and DATA lines 34F are parallel to each other and parallel to the VSS lines 35b in the field wiring, close to the terminals 32 and the terminal 33 for external connection. CLK lines 34E and DATA lines 34F have a wiring width of 25 to 100 μm, and VSS lines have a minimum width of wiring from 25 to 100 μm, lines are separated from each other with a gap width of 25 to 50 μm. More specifically, figure 7 and 8 VSS line 35b is connected with the adjacent VSS lines 35b by moving through the DATA line 34F. Accordingly, the structure of the grounding lines are located between the DATA lines 34F.

As described above, high-frequency CLK line and high frequency DATA line as the posting of the first logical signal is not adjacent to each other, but are located on the VSS lines inserted between them in the electric element 30 from the terminals 33 of the external connection up to the terminals 32. This structure prevents capacitive coupling between the wiring of the logical signals and the generation of noise.

Of VSS lines 35b only one (for example) VSS line connected to the terminal 32 and the terminal 33 for external connection. The rest of the VSS lines are not connected to the terminal 32 and the terminal 33 for external connection and end at the position near these terminals 32 and 33. This structure avoids increasing the number of VSS terminals in the terminals 32 and the terminals 14 on the substrate 10 of the recording elements corresponding to the terminals 32, preventing an increase in size of the recording head and suppressing the generation of noise.

As illustrated in Figure 9, the bottom layer of the wiring layers of logic signals includes a solid area VSS 35c, also have a VSS line 35b located across it. In this structure, the VSS line 35b is connected to the VSS region 35 through the through hole. VSS line 35b can be connected to VSS lines 35b by the offset.

In the first example implementation of the VSS line 35b located ogeny along CLK lines 34E and DATA lines 34F. The present invention, however, is not limited to such a structure, and, as illustrated in Figure 10, the line power source logic (VDD wiring) 36Cb can be located along the CLK lines 34E and DATA lines 34F. VDD wiring 36Cb provides a constant supply voltage logic circuits and has a relatively low current density. In the latter case also there is likely to generate noise that affect CLK lines 34E and DATA lines 34F.

Alternatively, CLK lines 34E and DATA lines 34F may be located adjacent to the LT lines (wiring locking signals) and HE lines (wiring heat enable signal as the second logical transaction. LE line and HE lines transmit signals LT (locking signals for temporarily storing recording data) and the signals HE (signals include heat, determine the period of time within which to give effect to the recording elements), which are second logic signals having components of lower frequency than the DATA components. In this case, it is also unlikely to generate noise affecting CLK lines 34E and DATA lines 34F.

In the first example implementation of the VSS line 35b are attached only to the DATA lines 34F outside wiring logic signals. The present invention, however, is not limited to such a structure, and VSS lines 35b can be located adjacent to prospect the vodka logic signals, which transmits logic signals having components with a frequency equal to the clock frequency, or half this frequency. Alternatively, the VSS line 35b can be located adjacent to all lines of logic signals. In the latter case, in particular, prevents the effects of noise, providing a more reliable recording head.

When electrical element 30 is provided with a wiring different from the wiring of the logical signals, which must be protected from noise, for example, posting a temperature measurement of the substrate 10 of the recording elements, then the transaction can be located adjacent to the VSS lines, as described above. This structure allows to accurately determine the temperature without the influence of noise.

On 11 and 12 illustrates another electrical wiring topology element 30 in accordance with the first exemplary embodiment. On Fig the scheme in the future. In this topology, the transaction terminal 33 for external connection are located on the lower layer due to the connection type of the recording head, and transaction logic signals and wiring system power supply connected to the terminals 33 for external connection on the lower layer to facilitate routing of wiring in the main unit of the recording device. Figure 11 and 12 shows that electromet iny element 30 has a wiring 34 logic signals, as in topology posting above, and wiring for the system 36b and 36c power sources. Between groups Postings inserted VSS line 35a, which must be connected to terminals 33 for external connection.

Line 34b of the logical signals in the upper layer are connected with lines 34c logical signals in the lower layer through a through hole in the area E, and, as in Fig.7-9, CLK lines and DATA lines are located adjacent to the VSS lines. VSS lines 35 on the lower layer are connected to VSS lines 35d on the top layer through the through hole, and a VSS line 35d are connected through a through hole with VSS lines 35a on the lower layer to be connected to terminals 33 for external connection, which leads to a continuous connection VSS lines 35.

In topology wiring, position Postings signal approximately corresponds to the positions of the VSS lines 35 through the adjacent wiring layers in the stack direction of the layers, but the wiring for the system power source is provided as part (area F on 11 and 12) topology. However, such parts are minimized in the above topology wiring. In addition, in this part of the topology, as illustrated in Fig, line 34b logic signals are perpendicular to the wiring systems 36A and 36B of the power source and have the magnetic field direction different from the direction of the magnetic field wiring systems 36A and 36B source Pete the tion, what prevents over noise. Therefore, this wiring topology also suppresses disturbances logic circuits due to noise and provides a highly reliable recording head.

In this topology also posting VSS line can be located adjacent to the wiring of the logical low frequency signals and other transactions that need to be saved from the noise.

On Fig illustrated a modified example topology wiring electrical element 30 in accordance with the first exemplary embodiment. Modified example includes the wiring of the logical signals on the upper and lower layers to further increase the number of substrates recording elements and reduce the size of the recording head.

In the wiring topology, illustrated in Fig, CLK lines 34E and DATA lines 34F adjacent to the VSS lines 35b on the same wiring layer, and also adjacent to the VSS lines 35b formed on another wiring layer in the stacking direction of the layers. This structure prevents the over noise, even when CLK lines 34E and DATA lines 34F pass through many layers.

In the wiring topology, illustrated in Fig, VSS line 35b have a wiring width greater than the width of the wiring CLK lines 34E and DATA lines 34F. This structure of the transaction weakens the capacitance between the wiring of the logical C the signals on different wiring layers, that also prevents the over the noise.

Also, in a modified example of the CLK lines 34E and DATA lines 34F may be located adjacent to the VDD wiring and the wiring of the logical low frequency signals. Alternatively, the VSS line can join other Postings logic signals.

As a modified example of the first embodiment, the electrical element 30 may have posted at the same level. In this case, the VSS line 35b are connected to one another via the through hole. Posting logic signals may be differential system.

In the exemplary embodiment, the electrical element has a two-layer structure, but may be adapted to three - or multi-layer structure. Alternatively, the electrical element may have a single layer structure.
