目前市面上常見的印表機除雷射印表機外，喷墨印表 機是另一種被廣泛使用的機種，其具有價格低廉、操作容 易以及低噪音等優點，且可列印於如紙張、相片紙等多種 喷墨媒體。而喷墨印表機之列印品質主要取決於墨水匣的 設計等因素，尤其以控制列印晶片釋出墨滴至喷墨媒體之 喷墨頭機構設計為墨水匣設計的重要考量因素。 一般而言，喷墨印表機主要藉由喷墨頭分別在一個陣 列的特定位置列印獨立點的圖案來組合產生列印的圖 像，而獨立點的位置是由所要列印的圖像所決定且可被看 做是一個直線陣列中的一個小點。 習知喷墨頭結構可包含列印晶片、加熱器以及喷孔 板，其中喷墨頭結構係组裝於一墨水匣之本體上，且加熱 器係受控於列印晶片，墨水匣將提供墨水至加熱器，使得 加熱器因應列印晶片的觸發對墨水進行加熱，使得墨水匣 内部所儲存之墨水加熱並經由所對應之喷孔板之噴孔喷 射至喷墨媒體上，至於，墨滴喷墨時間的控制對應於所要 列印圖案的像素點。 通常墨水匣係設置於喷墨印表機之内部，並藉由一承 1327529In addition to the laser printer, the inkjet printer is another widely used model. It has the advantages of low price, easy operation and low noise, and can be printed on paper. , photo paper and other inkjet media. 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 ink jet head structure may include a print wafer, a heater, and a orifice plate, wherein the ink jet head structure is assembled on the body of an ink cartridge, and the heater is controlled by the printing wafer, and the ink cartridge is provided. The ink is heated to the heater, so that 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 The control of the ink ejection time corresponds to the pixel point of the pattern to be printed. Usually the ink system is set inside the inkjet printer, and by one bearing 1327529

A phase play is generated along a woman's axis, wherein the scan axis refers to the direction of visibility parallel to the inkjet medium, and a single scan of the tilting assembly means that the carrier system drives the spray, head: approximately the entire inkjet medium Moving across the width once, however, between each single-human scan 'the inkjet media will advance relative to the inkjet head along a feed axis perpendicular to the axis of the woman, i.e., along the length of the inkjet media. When the inkjet moves along the scanning axis, a line of intermittent lines will be produced, and all the intermittent lines will be combined to form the printed pattern or the 'IV image as for the column along the feed axis of the inkjet medium. The print resolution is referred to as the density of the intermittent line d inkjet media feed axis, so the greater the density of the discontinuous lines on the inkjet media U, the higher the print resolution along that axis. The prior art improves the discontinuity by increasing the number of heaters of the inkjet head, the density of the inkjet hybrid (four), the resolution of the smear, and the speed of the lifting, although the heater of the inkjet head is increased. The number can be = printing speed, but many heaters generate a lot of heat, and the temperature of the head rises rapidly, which not only affects the printing quality, but also makes the entire inkjet head damaged. The solution developed by the ink head - By increasing the sneeze size to avoid a rapid rise in the temperature of the inkjet head, however, in the I inkjet printing market, the price reduction of the inkjet printer increases the cost of producing an inkjet printer. Moreover, when the number of nozzles of the inkjet head is large, the inkjet head design 6 1327529 is used for serial transmission to save the number of input/output (I/O) on the nozzle wafer, but because of the inkjet head wafer The control method for driving the heater is still required to combine the address control and print the data signal, but the design of the address control in the conventional inkjet head wafer is such that the number of addresses for controlling the inkjet head heating is η, position The decoder needs to set n rows of wires for connection to the corresponding inkjet driving circuit. For example, when the number of addresses for controlling the inkjet head heating is 20, the position decoder needs to set 20 cable lines correspondingly. However, as the number of heaters increases, the conventional design will increase the area of the wafer and increase the size of the ink jet head, so how to reduce the address control method is an important problem to save the wafer area. Therefore, how to develop a kind The invention can improve the above-mentioned monochrome inkjet head structure which is lacking in the prior art, and it is an urgent problem to be solved at present. SUMMARY OF THE INVENTION The main object of the present invention is to provide a monochrome inkjet head structure, which can solve the conventional problem of increasing the inkjet head. Increasing the size of the ink jet head by the number of heaters will increase the cost of producing an ink jet printer, and the conventional method of address control will increase the area of the wafer and increase the size of the ink jet head. Provided an ink jet head capable of high-resolution high-speed printing, and at the same time reducing costs by effectively utilizing the head space, providing a lightweight and inexpensive group To achieve high-performance printing. The inkjet head structure of the present invention is used to achieve high-resolution and high-speed printing by increasing the number of heaters and staggering different sets of heaters to make the heaters high. Frequency work. In order to achieve the above objectives, one of the cases in this case provides a kind of 7
