Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to an ink jet head structure, and more particularly to an ink jet head structure suitable for ink jet printing of single or multi-color ink. [Prior Art] _] Currently in the development of inkjet printing technology, the best and most effective way to improve the printing resolution and printing speed is to directly increase the number of heating elements on the inkjet wafer, that is, increase The number of orifices, while in the control of conventional heating elements, a single control element is controlled primarily by a single control contact. [0003] A circuit diagram for heating a heating element is shown. As shown in Fig. 1, the heating element 1G is connected between the drive control terminal i and the switch τ, and is connected to the (four) contact 13 and the ground by the drive control terminal < 4 door ^ Control contact 13 receiving - address 峨, used to control the switching elements such as pass and stop. For example, when the address signal of the control ship point __ is relatively high (High), the second signal is turned on, and the voltage signal P supplies power to the heating set 1Q to (4) the ink on the heating element i. (4) The nozzle hole (not _) should be sprayed to it. When the address signal A received by the control contact 13 is relatively logically low (Low), the switching element 12 is turned off. At this time, the heating element (4) supplies power, so that Add medium = method to perform inkjet work. τ止加热' thus no 100109990 However 'using the above method of controlling heating element heating, the number of heat elements to improve the resolution and printing of the surface ^ Form number A0101 To increase the overtime, the necessary page 4 / 6 Title [0004] 201238777 [0005] Ο [0006]

(4) and A(5)' to generate heating, and vice versa, when the apostrophe c(1) is disabled, for example, a state of relatively logic low (L〇w), the second ink jet unit 4d2 In response to the voltage ceremony p (丨) and a plurality of address signals A (3), A (4) and A (5), to generate heating. [0059] Similarly, the inkjet unit group of FIG. 8C is also one of a plurality of inkjet unit groups 4a-4m of the inkjet array 4, for example, when the timing 〇=13, it is the thirteenth jet. Ink unit set 4m. The thirteenth ink-ejection unit group 4m includes a first ink-jet unit 4ml and a second ink-ejection unit 4m2, and the first ink-ejection unit 4ml includes a fifteenth switch τ° M1 5 to twentieth-switching element M2丨And the third heating element H3, and the second inkjet unit 4m2 includes the twenty-second switching element 100109990 Form No. A0101 Page 30 / Total 6 100 Page 1002016866-0 201238777 Μ 22 ~ Twenty-sixth switching element Μ 26 and fourth heating The component Η4, and its connection mode and operation system are the same as the figure 7 and will not be described here. However, in the present embodiment, 'timing η = ΐ3, the first inkjet unit 4ml corresponds to the received voltage signal P(1), the plurality of address signals A(nl), A(n), and A(n+1). [0060] 006 [0061] Here, respectively, the twelfth address signal A (12), the thirteenth address signal A (13) and the first address signal a (1), and the selection signal c (1). The second ink jet unit 4m2 receives the voltage signal ρ(ι), the plurality of address signals A(12), A(13) and A(1). Wherein 'when the selection signal c(l) is enabled', the first inkjet unit 4ml generates a heating in response to the voltage signal ρ(ι) and the plurality of address signals A(12), A(13) and A(l)' Actuation, conversely, when the selection signal C(l) is disabled, the second inkjet unit 4m2 is responsive to the voltage signal P(l) and the plurality of address signals A(12), A(13) and Α(Γ), In order to generate heating action. In some embodiments, the inkjet array 4 can receive a single address signal a, where N is an integer, such as but not limited to n = 16, that is, the inkjet array 4 can receive 16 address jg numbers' And the timing ^ is = ι ~ 16. Therefore, when η = ι, the complex address signals are A(n-1)=16, A(n) = l and A(n+1) = 2, and when n = 16, multiple addresses The signal is 4 (11_1) = 15, A(n) = 16 and A(n + l) = l, whereby each of the ink jet unit groups of the ink jet array 4 is separately controlled to generate a heating operation. Please refer to FIG. 9A and FIG. 9B, wherein FIG. 9A is a timing chart of the first printing direction address signal of the embodiment of the present invention; the first drawing is a timing chart of the second printing direction address signal of the embodiment of the present invention. As shown in Figures 9A and 9B, the first printing direction, for example, the printing direction in the forward direction, that is, the plurality of address signals are sequentially outputted in a state of relatively high logic, and 100109990 Form No. A0101, page 31 / Total 60 pages 1002016866-0 201238777 The thirteenth address signal A (13) is output and then the first address signal A(l) is transmitted. Conversely, the second printing direction, for example, the reverse printing direction, that is, the state in which the plurality of address signals are relatively logic high is sequentially outputted by A(13)~A(1), and the first address signal is After the A(l) is rotated, the thirteenth address signal A(13) is connected, and the signal is transmitted repeatedly in a repeated manner to further enable the inkjet head (not shown) to perform bidirectional printing. [0063] Furthermore, according to the concept of the present invention, the bidirectional printing mechanism uses the previous address 彳§ person (11-1) and the latter address signal Α(η+ι) to achieve effective discharge. The purpose is to return the driven switching element to the initial state of no action. 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 address control method is used to reduce the size and area of the inkjet chip, and the wiring area of the inkjet chip of the inkjet head can be only about 75% to 63% of the total area of the inkjet wafer. For example, an inkjet wafer applied to a multi-color or monochrome inkjet head of a multi-ink supply tank, or a double ink supply tank respectively guides ink to a two-color or monochrome inkjet wafer via an ink supply passage, and a two-color inkjet wafer The wiring area is only about 75%~61% of the total area of the inkjet wafer. In the preferred embodiment, the three ink supply channels respectively guide the ink to the three-color or monochrome ink-jet wafer via the ink supply channel, and the one-color inkjet b The wiring area of the cymbal is only about π% to 62% of the total area of the inkjet wafer is a preferred embodiment; the inkjet wafer of the monochrome inkjet head of the single ink supply tank is taken as an example. The wiring area of the ink chip is only 80% to 63% of the total area of the ink-jet wafer as a preferred embodiment.
