Description of the invention: [Technical field to which the invention pertains] The present invention relates to an ink jet head structure, and more particularly to an ink jet head structure suitable for an ink cartridge. [Prior Art] In addition to the laser printers commonly used in the market, the inkjet printer is another widely used model, which has the advantages of low price, easy operation and low noise. Printed on a variety of inkjet media such as paper and photo paper. The printing quality of the inkjet printer mainly depends on factors such as the design of the ink cartridge, especially the ink jet head mechanism for controlling the printing of the ink droplets to the inkjet medium to design an ink cartridge design. In general, an inkjet printer mainly combines and produces a printed image by printing a pattern of independent dots at specific positions of an array, respectively, and the position of the independent dot is determined by the image to be printed. It is determined and can be seen as a small point in a linear array. The conventional inkjet head structure may include a printing chip, a heater, and a orifice plate, wherein the inkjet head structure is assembled on the body of an ink cartridge, and the heater is controlled by the printing wafer, and the ink cartridge provides ink. To the heater, the heater heats the ink according to the trigger of the printing of the wafer, so that the ink stored inside the ink cartridge is heated and ejected onto the inkjet medium through the corresponding orifice of the orifice plate, as for the ink droplet spraying The control of the ink time corresponds to the pixel point of the pattern to be printed. Usually, the ink system is set inside the inkjet printer, and is supported by a bearing 5 200840720. The carrier is two:: case: == position • The drawing axis produces relative motion, and the ink media is swept along the -. In the width direction, and the single field of the drive assembly is parallel to the f of the inkjet medium, the approximate load of the inkjet media, • %: front:, = two scan axis bars, and all the interleaving will result in intermittent media. The greater the depletion on the 5 axes, the printing resolution along the axis is known by increasing the number of heaters of the inkjet head by two. The density of the intermittent line along the advancement axis of the inkjet media is increased to increase the speed of printing. Although the heater of the inkjet head is increased: the thermal shock of the rate is increased to speed up the printing speed, but many heaters are produced. ^ Big interest points may cause the temperature of the ink jet head to rise rapidly, not only affecting = can cause damage to the entire ink jet head. One of the solutions developed by the industry at present is to avoid the rapid rise of the temperature of the inkjet head by the size of the _+ ink head, but in the inkjet printing market where the competition is fierce, inkjet The price of the printer has dropped rapidly. Increasing the size of the inkjet head will increase the cost of producing inkjet printers, while reducing market competitiveness. Moreover, when the number of nozzle holes of the nozzle head is set to be large, the inkjet head design 6 200840720 wheel is used to save the number of nozzle wafer wheel input/output (ι/〇), and the driving heat required for the ink head wafer is required. The control method of the device is still required to print the data signal, but the number of the conventional inkjet head wafer is designed to control the position of the inkjet head heated to the address A1. When the number of addresses of the ink-jet driving electric power for connecting the n-th cable to the main wish is 2 ,, when controlling the ink-jet head heating wire, the 时 时 解码 decoder needs to be set correspondingly 20 The increase in the area of the row, the conventional design will increase the wafer mode: save =: 4: To: - Head structure, each of which improves the inkjet of the above-mentioned conventional technology is only an urgent problem to be solved. SUMMARY OF THE INVENTION The main purpose of the increase 2 is to provide an ink jet head structure, which increases the number of heat generations and increases the size of the ink jet head, which will increase the cost of the wafer.

As for the density of the heater 35 on the above-mentioned calculation wafer 31, the area of the ink supply path 37 is added together for calculation. In addition to reducing the cost and increasing the printing speed by providing more heaters on the wafer to effectively utilize the head space, the ink jet head of the present invention can reduce the internal wafer of the ink jet head by reducing the cost of the ink jet head space.

The position signal of 42 is used to drive a heating circuit that needs to perform inkjet printing. The strobe signal is a signal for controlling the inkjet head wafer 42 to latch the signal transmitted from the inkjet control circuit 41, and the heating signal is The heating circuit of the inkjet head is printed with the signal of the ink droplet, and the preheating signal is a signal for preheating the inkjet head. Please refer to the fifth figure (a) and (b). The fifth figure (a) is the circuit structure diagram of the inkjet head wafer shown in the fourth figure, and the fifth figure (b) is the fifth figure (a). A schematic diagram of the circuit amplification structure of the C portion, as shown in the fifth diagram (a), because the inkjet control circuit 41 divides the data signal into odd address data in order to prevent the loss of the data signal transmitted to the inkjet head wafer 42. The signal and the even address data signal are respectively transmitted to the inkjet head wafer 42, so that the internal circuit of the inkjet head wafer 42 is divided into two parts to respectively receive the odd address data signal and the even address data signal and take the 16 200840720 with other The corresponding circuit is used for inkjet operation. The first part is to receive the odd address data signal (such as the left half of the fifth figure (a)) and the first serial data signal converter (ser 2 par_odd) 4211, a first serial address signal converter (ser 2 par-address) 4221, a first primary address decoder (MA) 4231, a first address decoder (SA) 4241, a first buffer (FireBuffer) , FB) 4251 and the circuit blocks constituting a plurality of groups (Ban The inkjet driving circuit 426 of k) is composed of. _ As for the second part, it is used to receive the even-numbered address data signal (such as the right half of the fifth picture (a)) and by the second serial data signal converter (ser 2 par-even) 4212, Second serial address signal converter (ser 2 par-address) 4222, second main address decoder (ma) 4232, second address decoder (SA) 4242, second buffer (卩11 ^ 丑11£^1%叩) 4252 and the ink jet driving circuit 426 constituting a plurality of groups of circuit blocks, since the circuit structure of the first part and the second part are substantially similar, the difference is only The data signals received by the first serial data signal converter 42Π' and the second #$ and the data signal converter 4212 are respectively an odd address or an even address, so the following will only receive the odd bit in the first part. The circuit of the left half of the address data signal is taken as an example, and the circuit of the right half of the even address data signal is no longer used. Referring to FIG. 5(b), the 'synchronous data signal converter 42ΐ is a clock signal (cl〇ck), an odd address data signal (Data-odd), and an output selected by the inkjet control circuit 41. Pass signal (str〇be), and convert the odd-numbered address data signal originally input into the serial port into a parallel signal output of 15 bits through the 〇d0~odl4 cable, and the first 17 200840720 The address number converter 4221 receives the clock signal (clock), the address signal (address) and the strobe k (strobe) which are rotated by the inkjet control circuit 41, and is originally in the position of the serial number. The address signal is converted into a parallel signal output of a total of 5 bits via the ~W and SO~S2 cables, wherein the signals output by m0~m2 are transmitted to the first primary address decoder 4231 and decoded. The parallel signal of the 5-bit output from the cable 〇~MA4 is transmitted to the first address decoder 4241 and decoded and outputted by the wires SA0 to SA3. The parallel signal of the bit. The first buffer 4251 receives the output of the inkjet control circuit 41. The thermal signal (MF) and the preheating signal (PF) are mainly used to remove the noise of the heating signal and the preheating signal and enhance the signal strength to increase the signal stability, and transmit the processed heating signal and the preheating signal to The inkjet driving circuit 426. Each of the inkjet driving circuits 426 mainly includes a gate 4261, a potential conversion circuit, a driving transistor 4263, and a heater R, and the gate 4261 has three pins - X, SA-Y And Data_Z, ΜΑ-X is connected to one of the wires MA〇~MA4, SA-Y is connected to one of the wires SA0~SA3, and Data_Z is connected to one of the wires 〇d〇~〇di4 And the gate 4261 will receive the address signals rotated by the first primary address decoder 4231 and the first address decoder 4241, and the countable address signals transmitted by the first serial data signal converter 4211. And performing a multiplication logic operation to output a different result 'that is, a high potential signal (high) or a low potential signal (1 〇 w). As for the potential conversion circuit, it can be a boost circuit (L-> Hcircuit) 18 200840720 4262, the system and the gate 4261 and the first slow The 425i is connected to receive the operation result of the switch 4261 and the heating signal (MF) and the preheating signal (pF) output by the first buffer 4251, and the operation result outputted by the gate is a low potential signal.

A column of printed voltage (Hv) is applied to the heater r such that the temperature of the heater #R will rise to preheat some of the ink and ink jet head to a specific temperature. ±Conversely, the result of the operation of the gate 4261 is that the high-potential signal boosting circuit 4262 will select the receiving heating signal (MF) and convert the heating m low potential into the high-powering ##, which is mainly used to trigger the driving power. The crystal 4263 is turned on while a printing voltage (HV) is delivered to the heater r. For example, the temperature of the heater R will rise to heat the ink to generate a bubble, which causes the ink to be ejected onto the inkjet medium. The inkjet driver circuit 426 included in the circuit block of each group corresponds to only one data line, that is, one of the wires 〇d〇 to 〇dl4, and the inkjet driving circuit 426 The number is equivalent to the number of address signals. In the inkjet head wafer 42 of the present invention, the address signals are mainly divided into a primary address signal and a secondary address signal, that is, the conventional technique uses a single address de-emphasis device.

The bits, M and N are natural numbers, causing the first primary address decoder 4231 and the first address decoding 4241 to form a MxN row parallel signal to be delivered to the inkjet drive having the gates 4261 and 19 200840720 heater R. Circuit 426 acts as an inkjet control signal. In this embodiment, the main address signal is responsible for 5 bits, the secondary address signal is responsible for 4 bits, and the main address signal is the 5 bits rotated by the first main address decoder 4231 via the lines MA0 to MA4. The meta-parallel signal, that is, m=5, the secondary address signal is the 4-bit parallel signal output by the first address decoder 4241 via the lines SA0 to SA3, that is, n=4, the main address signal and the sub-bit After the address signal is multiplied by the gate 4261, it can be generated to be the same as the original address number, ie, MxN=5x4=20, which can solve the problem that the conventional technology needs to set 2 lines and increase the wafer layout (lay〇ut). The size of the problem, in turn, to achieve the reduction of the area of the inkjet head wafer occupied by the emission reduction line to reduce the wafer area 'to make the size of the inkjet head relatively narrow, thereby reducing the cost of producing inkjet printers. Please refer to the following list 1. It is the parallel address signal of the m〇~m2棑 line to the first main position=decoder 4231, and the s〇~S2 line input to the first address decoder 4241.

Adjustment may be required. For example, when the number of control addresses is 16, the number of lines of the first primary address decoder 4231 may be M=4, and the first address decoder 4241 is also maintained at N=4. After multiplying the two, MxN = 4x4 = 16. 21 200840720 In summary, the ink jet head structure of the present invention mainly uses a staggered arrangement to place more heaters on the wafer to effectively utilize the head space to reduce cost and increase printing speed, and more Replacing the conventional single address decoder with the primary address decoder and the secondary address decoder, reducing the layout area of the wafer inside the inkjet head to reduce the wafer area, and the size of the inkjet head is relatively reduced. , thereby reducing the cost of producing inkjet printers.
