The technical field to which the invention relates

The present invention relates to an element substrate, which is resistant to operational errors caused by noise, which is generated due to fluctuations of current, capable of printing and is suitable, in particular, to an inkjet printhead, and the printhead, the cartridge head and the printer that uses this element substrate.

The level of technology

Known ink-jet printhead, which produces ink from a variety of outlets using thermal energy. To obtain stable characteristics of the issue in the printhead to the heaters is necessary to apply a stable voltage. Element substrate, printhead has many matrices heaters. When all the heaters are one matrix heaters are excited simultaneously, through the grounding circuit and supply circuit excitation, designed to power the heaters, flows a large current due to the resistance of the above-mentioned circuits is a significant voltage drop. If the voltage applied to the heaters varies due to voltage drop, it also varies the quantity of ink, and to obtain a stable characteristic of a difficult issue. To prevent voltage drop and get Tabellini characteristics of production in modern element substrates printhead is limited to the number of heaters, that fire simultaneously. In particular, the heaters are divided into a predefined number of blocks and are excited sequentially, using the so-called excitation with time division, thereby applying to the heaters stable voltage (Publication No. 07-68761 Japanese patent).

As described above, when multiple heaters are excited simultaneously, through the food chain excitation and the grounding circuit flows a large current. In this case, the noise generated due to fluctuations of the current, which is generated by inductive coupling in chains TAB (Tape Automated Bonding, Automated Assembly tape) printhead causing the problem. Chain TAB provided on one side of the substrate to reduce costs and facilitate the manufacture of the printhead. Therefore, the power supply circuit excitation designed for the application of the excitation voltage to the heaters on the element substrate, the grounding circuit and circuit logic signals intended for transmission of a signal in a logic circuit on the element substrate, are formed in parallel. Therefore, the noise generated by inductive coupling, is superimposed on the gate signal. This can cause operating error logic circuit provided on the element substrate. To prevent this phenomenon, the element p is dajka, in which the applied excitation with time division, delay timings of excitatory impulses, which must be filed with the heaters in the selected block, in the order of nanoseconds. Thus, decreases the current flowing per unit of time, whereby preventing noise generation and operational errors logic circuit on the element substrate.

For a high-quality image in modern inkjet printing devices manufactured ink droplets are becoming more and more small. Together with the improvement of image quality required increase printing speed. However, it is difficult to realize high-speed printing, if the manufactured ink droplets are small. For example, if the quantity of ink is reduced to 1/2, the number of editions of ink should be increased in two times. Therefore, the printing speed is reduced to 1/2.

To prevent the reduction of the printing speed, caused by small drops of ink to a print medium you make the same amount of ink per unit of time as before. The decrease in printing speed can be prevented by increasing the number of heaters arranged on the element substrate. However, if you simply increase the number of heaters without changing the intervals between them, the element substrate becomes large, and the printhead, comprising the elemental substrate becomes cumbersome. In the printing process, the print head moves to the ink jet printing device at high speed. Hence, bulky printhead generates vibration and noise. Bulky printhead also increases the cost. To increase the number of heaters without changing the size of the element substrate has been proposed a method of increasing the density of the heaters.

When the density of the heaters increases, also increases the number of heaters, which must be actuated at the same time. Also when increasing the number of heaters, which must be actuated at the same time, additionally increases the current flowing through the power supply circuit excitation. For this reason, the traditional way delay using excitation with a time separation is unlikely to prevent the noise generated due to fluctuations of the current, which is generated by inductive coupling in chains TAB printhead.

The aim of the present invention is the elemental substrate and the printhead, the cartridge head and a printing device that uses this element substrate.

predstavljaetsja possible to provide the element substrate, in which the printing elements are arranged with high density and which prevents operating errors logic circuit by suppressing noise generated due to fluctuations of the current, which is generated due to the increase in current at the initiation of printing elements. Also it is possible to provide the printhead, the cartridge head and a printing device that uses this element substrate.

The first option exercise

Figure 1 illustrates a circuit portion formed on the second element substrate H1101 this option implementation. Figure 1 is a schematic diagram illustrating heaters (printing elements) and excitatory circuits. Referring to Figure 1, input terminal HE enters an activation signal to the heating circuit 101 delay circuit 101 delays delays the activation signal to the heating. Group 102-1 and 102-2 heaters are used as the printing elements to heat and release the ink. Transistor group 103-1 and 103-2 excite groups 102-1 and 102-2 heaters. The group 104 of the valve control transistor groups 103-1 and 103-2. Scheme-latch 105 latches the data that must be transferred to transistor group 103-1 and 103-2 through gr is PPI 104 of valve control. Logic circuit 106 selection unit activates each control valve from the group 104 of the control valves in accordance with the block, activated with time division.

Logic circuit 106 selecting unit that includes a decoder that can consistently assign multiple blocks. For convenience of illustration shown here is only one circuit for selecting one of the block through a decoder.

When there are many blocks, input terminals VH1 and VH2 for input voltage and input terminal for HE input signal for activating the heating is usually connected with many blocks.

The signal HE1 activates a specific control valve from the group 104 of the control valves to a predetermined period. The signal HE2 is obtained by delaying the signal HE1, using circuit 101 delays. The HE3 signal obtained by delaying the signal HE2 using circuit 101 delays. The signal HE4 is obtained by delaying the signal HE3 using circuit 101 delays. Input terminal VH1 is a combination of circuit excitation to supply the excitation voltage on the group 102-1 heaters. Input terminal VH2 is a combination of circuit excitation to supply the excitation voltage on the group 102-2 heaters. Electrode terminal GNDH1 is a combination of circuits grounding groups 102-1 heaters. Electrode terminal GNDH2 presented yet a bunch of chains ground group 102-2 heaters.

Referring to Figure 1, excited all the heaters in groups 102-1 and 102-2 heaters, selected logic 106 unit selection. In this case, first, the input terminal HE enters the signal HE1, to control valves 104-1A and 104-1b, so that the exciting pulse signal is supplied to the heaters 102-1A and 102-1b. Further, the signal HE2 obtained by delaying signal HE1 to a predetermined time interval by using the circuit 101 delays introduced in the valves 104-2A and 104-2b control, so that a stimulating pulse signal delayed for the predetermined time is supplied to the heaters 102-2A and 102-2b. The HE3 signal obtained by delaying the signal HE2 at the predetermined interval by using the circuit 101 delays introduced in the valves 104-1C and 104-1d control, so that a stimulating pulse signal delayed for the predetermined time is supplied to the heaters 102-1C and 102-1d. And, finally, the signal HE4 obtained by delaying the signal of HE3 to a predetermined time interval by using the circuit 101 delays introduced in the valves 104-2C and 104-2d control, so that a stimulating pulse signal delayed for the predetermined time is supplied to the heaters 102-2C and 102-2d. Thus, the heaters are initiated in the following order: 102-1a and 102-1b, 102-2a and 102-2b, 102-1c and 102-1d, and 102-2c and 102-2d.

According to this variant implementation heaters groups 102-1 heaters, which is alucam the excitation voltage from the input terminals VH1, and heaters group 102-2 heaters, which receives the excitation voltage from the input terminal VH2, excited alternately in the order of time intervals of the signal delay activation of the heating. That is, in this embodiment, the current which flows in the excitation heaters, never occurs to one input terminal continuously; he alternately flows to the input terminals VH1 and VH2.

Fig.7 represents a timing diagram illustrating the delay of the current flowing to the heaters according to the first variant implementation. First, the current IH_102-1a/1b heater flows to the heaters 102-1a and 102-1b, which receive the excitation voltage from the input terminals VH1. Further, in 1/3 × tDL seconds, the current IH_102-2a/2b heater flows to the heaters 102-2a and 102-2b, which receives the excitation voltage from the input terminal VH2. Another 1/3 × tDL seconds current IH_102-1c/1d heater flows to the heaters 102-1c and 102-1d, which receive the excitation voltage from the input terminals VH1. And another 1/3 × tDL seconds current IH_102-2c/2d heater flows to the heaters 102-2c and 102-2d, which receive the excitation voltage from the input terminal VH2. All heaters are excited during the time tDL.

The second option exercise

Fig.9 illustrates a circuit portion formed on the element substrate H1101 this option to implement the Oia. Fig.9 is a schematic diagram illustrating heaters (printing elements) and their exciting scheme. Signal line signal activating the heating, which enables the group 104 of the valve to a predetermined period of time, bursts into a node 109 in the direction of the input terminals VH1 and side input terminal VH2. In this embodiment, as in the first embodiment, illustrated only scheme for the excitation of a single block.

Signal activation heating, allocated to input terminals VH1 and VH2 in the node 109, the activation of heating, branching toward the input terminal VH2 delay circuit 107 delay. Signal 1 HE activates specific valve from the group 104 of the valve to a predetermined period. The signal HE2 is obtained by delaying the signal HE1, using the scheme 107 delay. The HE3 signal obtained by delaying the signal HE1, using circuit 101 delays. The signal HE4 is obtained by delaying the signal HE2 using circuit 101 delays.

Referring to Fig.9, excited all the heaters in groups 102-1 and 102-2 heaters. In this case, first, the input terminal HE enters the signal HE1 in the valves 104-1c and 104-1d, so that the exciting pulse signal is supplied to the heaters 102-1c and 102-1d. Further, the signal HE2 obtained by delaying signal HE1 to a predetermined time interval by using the schema are, entered the gates 104-2A and 104-2b, so that the exciting pulse signal delayed for the predetermined time is supplied to the heaters 102-2A and 102-2b. The delay time of signal activation of the heat generated by the circuit 107 delay shorter than the time delay produced by the circuit 101 delays. The HE3 signal obtained by delaying the signal HE1 at the predetermined time using the circuit 101 delays introduced in the valves 104-1a and 104-1b, so that the exciting pulse signal delayed for the predetermined time is supplied to the heaters 102-1a and 102-1b. And finally the signal HE4 obtained by delaying signal HE2 at the predetermined interval by using the circuit 101 delays introduced in the valves 104-2C and 104-2d, so that the exciting pulse signal delayed for the predetermined time is supplied to the heaters 102-2C and 102-2d. Thus, the heaters are an activation signal to the heating in order of decreasing distances to node 109. When the time delay circuit 107, the delay is 1/2 the time delay circuit 101 delays, heaters signals activation of the heating detained at equal time intervals. The heaters are initiated in the following order: 102-1c and 102-1d, 102-2a and 102-2b, 102-1a and 102-1b, and 102-2c and 102-2d.

According to this variant implementation heaters groups 102-1 heaters, which receives the excitation voltage from the input Clem is s VH1, and heaters group 102-2 heaters, which receives the excitation voltage from the input terminal VH2, excited alternately in the order of time intervals of the delay. That is, in this embodiment, the current which flows in the excitation heaters, never occurs to one input terminal continuously; he alternately flows to the input terminals VH1 and VH2. In this embodiment, the number of heaters on the side of the input terminals VH1 equal to the number of heaters on the side of the input terminal VH2. Therefore, the signal line signal activating the heating branches in the node 109, so that the divided line are equal or nearly equal length sides of the input terminals VH1 and VH2. This allows you to initiate heaters consistently at predefined intervals of time without any impact on the difference in the lengths of the chains.

Comparative example

6 is a schematic diagram illustrating a comparative example of the above-described embodiments. Referring to Fig.6, excited all the heaters in groups 102-1 and 102-2 heaters, selected logic 106 unit selection. In this case, first, the input terminal HE enters the signal HE1 in the valves 104-1A and 104-1b control, so that a stimulating pulse signal is supplied to the heaters 102-1A and 102-1b. Further, the signal HE2 obtained by delaying signal HE1 to a predetermined time interval by using the circuit 101 delays, entered the gates 104-1C and 104-1d control, so that a stimulating pulse signal delayed for the predetermined time is supplied to the heaters 102-1C and 102-1d. The HE3 signal obtained by delaying the signal HE2 at the predetermined interval by using the circuit 101 delays introduced in the valves 104-2A and 104-2b control, so that a stimulating pulse signal delayed for the predetermined time is supplied to the heaters 102-2A and 102-2b. And finally the signal HE4 obtained by delaying the signal of HE3 to a predetermined time interval by using the circuit 101 delays introduced in the valves 104-2C and 104-2d control, so that a stimulating pulse signal delayed for the predetermined time is supplied to the heaters 102-2C and 102-2d. Thus, the heaters are initiated in the following order: 102-1a and 102-1b, 102-1c and 102-1d, 102-2a and 102-2b, and 102-2c and 102-2d.

Figa and 8B are diagrams illustrating the ascending currents flowing to the circuit excitation. On Figa and 8B, as follows: Δi is the current flowing to the input terminals VH1 and VH2 in the excitation of one set of heaters, Δt1 is the time delay tDL is the total time delay from the moment of initiation of the first heater before the initiation of the last of the heater.

Figa is a graph illustrating the ascending currents when using heaters and excite them what their circuit of the comparative example. First, excitatory heaters that receive excitation voltage from the input terminals VH1. Through time Δt1 excited heaters, which also receive the excitation voltage from the input terminals VH1. That is, all excited heaters that receive excitation voltage from the input terminals VH1. In another time Δt1 in the same way excited heaters that receive excitation voltage from the input terminal VH2.

FIGU is a graph illustrating the ascending currents when using heaters and their excitatory circuit according to the first and second variants of implementation. First, excitatory heaters that receive excitation voltage from the input terminals VH1. Through the time delay Δt1 excited heaters that receive excitation voltage from the input terminal VH2. After another time delay Δt1 excited heaters that receive excitation voltage from the input terminals VH1. And finally, after another time delay Δt1 excited heaters that receive excitation voltage from the input terminal VH2.

In the first and second embodiments, the implementation of heaters that receive excitation voltage from the input terminals VH1, and heaters that receive excitation voltage from the input terminal VH2, alternately excited. The investigator is about, the time delay Δt2 for each of the input terminals of the VH1 and VH2 twice the time delay Δt1.

According to the first and second variants of the implementation it is possible to halve the increase in the current flowing to the power supply circuit of the excitation in the circuit TAB without changing the total time delay.

In both cases, the implementation of the element substrate has two input terminals to supply the excitation voltage to the heater. Elemental substrate can have multiple input terminals (three or more terminals).

In both cases, the implementation of each group of heaters, which receives the excitation signals delayed by the delay circuit to a predetermined number of stages includes two heater. However, the number of heaters that are included with each group of heaters can be set to 1 or 3 or more.

In both cases, the implementation of the element substrate uses heaters as the printing elements. The element substrate may be used, for example, piezoelectric elements as printing elements.

In the present invention, the number of heaters that must be raised in one block is not limited. Therefore, it is possible to obtain the optimum conditions by combining the delay time, the number of blocks, the number of the ETS heaters, which shall be made in one unit, etc. in the element substrate heaters, which are arranged with high density.

As described above, even when the number of heaters that must be initiated increases, the present invention provides the ability to suppress the increase in the current flowing to the input terminal to supply the heaters of the excitation voltage. Therefore, it is possible to prevent the generation of noise in electrical circuits TAB which occur as a result of increasing the current flowing to the circuit excitation, and to prevent operating errors logical schema.
