Description
本案係關於一種噴墨單元組，尤指一種適用於噴墨頭控制電路之噴墨單元組。The present invention relates to an ink jet unit group, and more particularly to an ink jet unit group suitable for an ink jet head control circuit.
目前於噴墨列印的技術發展中，能夠提高列印解析度及列印速度之最佳及最有效的方法，即是直接增加加熱元件的數量，而在傳統加熱元件的控制上，主要是透過單一個控制接點來控制單一個對應的加熱元件。At present, in the development of inkjet printing technology, the best and most effective method for improving the resolution and printing speed of printing is to directly increase the number of heating elements, and in the control of conventional heating elements, mainly A single corresponding heating element is controlled by a single control contact.
請參閱第一圖，其係為傳統控制加熱元件加熱之電路架構示意圖。如第一圖所示，加熱元件10連接於驅動控制端11及開關元件12之間，並由驅動控制端11接收一電壓信號P，而開關元件12連接於控制接點13及接地端14之間，且由控制接點13接收一位址信號A，用以控制開關元件12之導通與截止。舉例而言，當控制接點13所接收之位址信號A為相對邏輯高電位(High)時，開關元件12導通，此時，電壓信號P提供電能予加熱元件10，以使流經加熱元件10上之墨水由對應的噴孔(未圖示)噴塗至列印載體上。反之，當控制接點13所接收之位址信號A為相對邏輯低電位(Low)時，開關元件12截止，此時，電壓信號P中斷對加熱元件10提供電能，使加熱元件10停止加熱，因而無法進行噴墨的工作。Please refer to the first figure, which is a schematic diagram of the circuit structure of the traditional control heating element heating. As shown in the first figure, the heating element 10 is connected between the driving control terminal 11 and the switching element 12, and receives a voltage signal P from the driving control terminal 11, and the switching element 12 is connected to the control contact 13 and the grounding terminal 14. The address signal A is received by the control contact 13 to control the on and off of the switching element 12. For example, when the address signal A received by the control contact 13 is relatively high (High), the switching element 12 is turned on. At this time, the voltage signal P supplies power to the heating element 10 to flow through the heating element. The ink on the 10 is sprayed onto the print carrier by a corresponding orifice (not shown). On the contrary, when the address signal A received by the control contact 13 is relatively low logic (Low), the switching element 12 is turned off. At this time, the voltage signal P interrupts the supply of electric energy to the heating element 10, so that the heating element 10 stops heating. Therefore, the operation of the ink jet cannot be performed.
然而，使用上述控制加熱元件的方法，若要增加加熱元件以提高列印解析度及列印速度時，勢必需要增加控制接點的數目，以分別控制各個加熱元件，因此會使得噴墨晶片(未圖示)的整體面積增大且其生產成本也必須提高。However, with the above method of controlling the heating element, if the heating element is to be increased to improve the printing resolution and the printing speed, it is necessary to increase the number of control contacts to separately control the respective heating elements, thus making the ink-jet wafer ( The overall area of the unillustrated) is increased and the production cost thereof must also be increased.
另外，為了達到減少控制接點的目的，利用N-MOS元件來設計加熱元件運作之控制方法便因應而生，但若要再進一步增加加熱元件時，仍須增加對應的控制接點。故，目前更提出使用C-MOS元件的控制方式，來解決當控制接點增加時噴墨晶片面積增大的問題，但C-MOS元件的製造成本較N-MOS元件的製造成本高出許多，因此仍無法廣為應用。In addition, in order to achieve the purpose of reducing the control contact, the control method of designing the operation of the heating element by using the N-MOS element is made, but if the heating element is further increased, the corresponding control contact must be added. Therefore, the control method of the C-MOS device is proposed to solve the problem of an increase in the area of the ink-jet wafer when the control contact is increased, but the manufacturing cost of the C-MOS device is much higher than the manufacturing cost of the N-MOS device. Therefore, it is still not widely used.
本案之目的為提供一種噴墨單元組，其可於需要增加加熱元件以提高列印解析度及列印速度時，減少位址信號(即控制接點)的數目，以達到縮小噴墨晶片的整體面積以及降低噴墨晶片之生產成本的目的。另外，本案係利用N-MOS開關元件之電路設計，以選擇性地控制噴墨之作動，亦可達到降低製造N-MOS開關元件成本的目的。The purpose of the present invention is to provide an ink jet unit set which can reduce the number of address signals (ie, control contacts) when the heating element needs to be increased to improve the printing resolution and printing speed, so as to reduce the size of the inkjet wafer. The overall area and the purpose of reducing the production cost of the inkjet wafer. In addition, the present invention utilizes the circuit design of the N-MOS switching element to selectively control the operation of the ink jet, and also achieves the purpose of reducing the cost of manufacturing the N-MOS switching element.

請參閱第三圖B並配合第三圖A，其中第三圖B係為第三圖A所示之噴墨單元組之電路作動信號順向時序示意圖。如第三圖A及B所示，根據本案之構想，當第一選擇信號C(1)與第二位址信號A(2)同時為相對邏輯高電位之情況下，即V(C(1))=1、V(A(2))=1，第四開關元件M4 將導通，於此同時，第二位址信號A(2)通過第四開關元件M4 亦使第五開關元件M5 導通，且第五開關元件M5 與接地端23連接，因此選擇性地使電壓信號P(1)提供電能至第一加熱元件H1 。舉例而言，電壓信號P(1)為相對邏輯高電位之情況下，即V(P(1))=1，電壓信號P(1)會驅動第一加熱元件H1 加熱，並使流經第一加熱元件H1 之墨水經由對應之噴孔(未圖示)噴塗至列印載體，例如紙張，以順利完成噴墨的動作。另一方面，由於第二選擇信號C(2)，例如用以驅動N-MOS開關元件之控制信號，為相對邏輯低電位，即V(C(2))=0，第九開關元件M9 係-為截止，進而使第十開關元件M10 亦為-截止，因此電壓信號P(1)無法提供電能至第二加熱元件H2 ，而使第二加熱元件H2 無法被驅動加熱。Please refer to the third figure B and cooperate with the third figure A, wherein the third figure B is a schematic diagram of the sequence of the circuit actuation signals of the inkjet unit group shown in the third figure A. As shown in the third figure A and B, according to the concept of the present case, when the first selection signal C(1) and the second address signal A(2) are relatively logic high, that is, V(C(1) )) = 1, V (A (2)) = 1, the fourth switching element M 4 will be turned on, at the same time, the second address signal A (2) through the fourth switching element M 4 also makes the fifth switching element M 5 is turned on, and the fifth switching element M 5 is connected to the ground terminal 23, so that the voltage signal is selectively P (1) providing a first electrical energy to the heating element H 1. For example, the voltage signal P (1) is at a high logic potential of the opposite, i.e., V (P (1)) = 1, the voltage signal P (1) drives the heating element H 1 a first heating, and flows through a first heating element H 1 of the ink through the spray orifice (not shown) to correspond to the print carrier, such as a paper, to the successful completion of the operation of the ink jet. On the other hand, since the second selection signal C (2), for example, a control signal for driving the switching elements of the N-MOS, relatively logic low, i.e., V (C (2)) = 0, the ninth switching element M 9 The system is turned off, and the tenth switching element M 10 is also turned off. Therefore, the voltage signal P(1) cannot supply electric power to the second heating element H 2 , and the second heating element H 2 cannot be driven and heated.
此外，當第一選擇信號C(1)轉變為一相對邏輯低電位，即V(C(1))=0時，第四開關元件M4 及第五開關元件M5 將截止，此時，由於電壓信號P(1)提供至第一加熱元件H1 之電能無法接地，使得第一加熱元件H1 將停止進行該加熱之作動。Further, when the first selection signal C (1) into a relatively low logic level, i.e., V (C (1)) = 0 , the fourth switching element and the fifth switching element M 4 M 5 will be turned off at this time, Since the voltage signal P (1) supplied to the first power of the heating element H 1 can not be grounded, so that the first heating element H 1 will stop the heating of the actuator.
再者，當第二位址信號A(2)持續為相對邏輯高電位且第二選擇信號C(2)亦為相對邏輯高電位，即V(A(2))=1、V(C(2))=1之情況下，第九開關元件M9 將導通，使得第二位址信號A(2)可通過第九開關元件M9 控制第十開關元件M10 導通，進而選擇性地使電壓信號P(1)提供電能至第二加熱元件H2 。同理，驅動第二加熱元件H2 加熱，並使流經第二加熱元件H2 之墨水經由對應之噴孔噴塗至列印載體上，以順利完成噴墨的動作。在此同時，由於第二共接點221上之電能V(Kb )係為一相對邏輯高電位，即V(Kb )=1，或者，第一位址信號A(1)或第三位址信號A(3)其中之一位址信號為相對邏輯高電位時，即V(A(1))=1或V(A(3))=1，將分別使得第一噴墨單元21之第三開關元件M3 、第一開關元件M1 或第二開關元件M2 導通，因此殘留於第一共接點211上之電能V(Ka )將經由第三開關元件M3 、第一開關元件M1 或第二開關元件M2 其中之一開關元件被導引至接地端23，進而使第一共接點211上之電能V(Ka )降至0V，且使第五開關元件M5 回復到未動作之初始狀態。Furthermore, when the second address signal A(2) continues to be relatively logic high and the second selection signal C(2) is also relatively logic high, ie V(A(2))=1, V(C( 2)) = 1 in the case of the ninth switching element M 9 will be turned on, so that the second address signal A (2) through the ninth switching element M 9 M 10 control tenth switching element is turned on, and thus selectively voltage signal P (1) supplying power to the second heating element H 2. Similarly, the second heating element H 2 is driven to heat, and the ink flowing through the second heating element H 2 is sprayed onto the printing carrier via the corresponding orifice to smoothly complete the inkjet operation. At the same time, since the electric energy V(K b ) on the second common contact 221 is a relatively logic high potential, that is, V(K b )=1, or the first address signal A(1) or the third When one of the address signals A(3) is relatively logic high, that is, V(A(1))=1 or V(A(3))=1, the first ink-ejection unit 21 will be caused, respectively. The third switching element M 3 , the first switching element M 1 or the second switching element M 2 are turned on, so the electric energy V(K a ) remaining on the first common contact 211 will pass through the third switching element M 3 , One of the switching elements M 1 or the second switching element M 2 is guided to the ground terminal 23, thereby reducing the electric energy V(K a ) on the first common contact 211 to 0V, and making the fifth switch Element M 5 returns to the initial state of no action.
於本實施例中，由於複數個位址信號A(1)、A(2)及A(3)具有週期性輸出之特性，使得電路將週期性地重複上述之運作，並進行噴墨的工作。因此，當第二位址信號A(2)及第一選擇信號C(1)再度轉變為相對邏輯高電位且第二選擇信號C(2)轉變為相對邏輯低電位時，第一共接點211上之電能V(Ka )係為相對邏輯高電位，即V(Ka )=1，將使得第二噴墨單元22之第八開關元件M8 導通，或者，第一位址信號A(1)或第三位址信號A(3)其中之一位址信號為相對邏輯高電位時，第六開關元件M6 或第七開關元件M7 導通，此時，殘留於第二共接點221上之電能V(Kb )將經由第八開關元件M8 、第六開關元件M6 或第七開關元件M7 其中之一開關元件被導引至接地端23，使得第二共接點221上之電能V(Kb )降至0V，並使第十開關元件M10 截止，且第二加熱元件H2 無法被驅動加熱，藉此達到確保同一時間內僅有第一噴墨單元21或第二噴墨單元22之任單一個噴墨單元，進行加熱之作動。In this embodiment, since the plurality of address signals A(1), A(2), and A(3) have periodic output characteristics, the circuit will periodically repeat the above operations and perform inkjet work. . Therefore, when the second address signal A(2) and the first selection signal C(1) are again converted to a relatively logic high potential and the second selection signal C(2) is converted to a relatively logic low level, the first common contact The electric energy V(K a ) on 211 is a relatively logic high potential, that is, V(K a )=1, which will cause the eighth switching element M 8 of the second ink ejection unit 22 to be turned on, or the first address signal A (1) or the third address signal A (3), wherein one of the address signals is relatively logic high, the sixth switching element M 6 or the seventh switching element M 7 is turned on, and at this time, remains in the second common connection The electric energy V(K b ) at the point 221 will be guided to the ground terminal 23 via one of the eighth switching element M 8 , the sixth switching element M 6 or the seventh switching element M 7 so that the second common connection The electric energy V(K b ) at point 221 drops to 0V, and the tenth switching element M 10 is turned off, and the second heating element H 2 cannot be driven and heated, thereby ensuring that only the first ink ejection unit is in the same time. 21 or a single ink jet unit of the second ink jet unit 22 performs heating operation.
由上述可知，本實施例之噴墨單元組2之第一噴墨單元21係由第一開關元件M1 、第二開關元件M2 或第三開關元件M3 其中之一開關元件來達到放電的目的，以及第二噴墨單元22係由第六開關元件M6 、第七開關元件M7 或第八開關元件M8 其中之一開關元件來達到放電的目的。另外，本案之噴墨單元組2僅需使用一電壓信號P(1)、複數個位址信號A(1)、A(2)與A(3)以及第一選擇信號C(1)與第二選擇信號C(1)，即可選擇性地控制第一加熱元件H1 及第二加熱元件H2 加熱，進而達到噴墨的目的。It can be seen from the above that the first ink-ejection unit 21 of the ink-jet unit group 2 of the present embodiment is discharged by one of the first switching element M 1 , the second switching element M 2 or the third switching element M 3 . The purpose of the second ink-jet unit 22 is to discharge by one of the sixth switching element M 6 , the seventh switching element M 7 or the eighth switching element M 8 . In addition, the inkjet unit group 2 of the present invention only needs to use a voltage signal P(1), a plurality of address signals A(1), A(2) and A(3), and a first selection signal C(1) and two selection signals C (1), to selectively control the first heating element and the second heating element H 1 H 2 heat, thus achieving the purpose of the ink jet.
請參閱第三圖C並配合第三圖A，其中第三圖C係為第三圖A所示之噴墨單元組之電路作動信號逆向時序示意圖。如第三圖A及C所示，根據本案之構想，當第二選擇信號C(2)與第二位址信號A(2)同時為相對邏輯高電位之情況下，即V(C(2))=1、V(A(2))=1，第九開關元件M9 將導通，於此同時，第二位址信號A(2)通過第九開關元件M9 亦使第十開關元件M10 導通，且第十開關元件M10 與接地端23連接，因此選擇性地使電壓信號P(1)提供電能至第二加熱元件H2 ，藉此驅動第二加熱元件H2 加熱，並使流經第二加熱元件H2 之墨水經由對應之噴孔噴塗至列印載體，以順利完成噴墨的動作。另一方面，由於第一選擇信號C(1)為相對邏輯低電位，即V(C(1))=0，第四開關元件M4 係-為截止，並使第五開關元件M5 -截止，因此電壓信號P(1)無法提供電能至第一加熱元件H1 ，而使第一加熱元件H1 無法被驅動加熱。Please refer to the third figure C and cooperate with the third figure A, wherein the third figure C is a reverse timing diagram of the circuit actuation signal of the ink jet unit group shown in the third figure A. As shown in the third diagrams A and C, according to the concept of the present case, when the second selection signal C(2) and the second address signal A(2) are simultaneously at a relatively high logic level, that is, V(C(2) )) = 1, V (A (2)) = 1, the ninth switching element M 9 will be turned on, at the same time, the second address signal A (2) through the ninth switching element M 9 also makes the tenth switching element M 10 is turned on, and the tenth switching element M 10 is connected to the ground terminal 23, so that the voltage signal is selectively P (1) supplying power to the second heating element H 2, thereby driving the second heating element is heated H 2, and The ink flowing through the second heating element H 2 is sprayed onto the print carrier via the corresponding orifice to smoothly complete the ink jetting operation. On the other hand, since the first selection signal C (1) relative logic low, i.e., V (C (1)) = 0, the fourth switching element M 4 lines - is turned off, and the fifth switching element M 5 - turned off, the voltage signal P (1) can not provide power to the first heating element H 1, the first heating element H 1 can not be driven heating.
此外，當第二選擇信號C(2)轉變為一相對邏輯低電位，即V(C(2))=0時，第九開關元件M9 及第十開關元件M10 將截止，使得第二加熱元件H2 將停止進行加熱之作動。Further, when the second selection signal C (2) into a relatively low logic level, i.e., V (C (2)) = 0 , the ninth switching element M 9 and M 10 the tenth switching element is turned off, so that the second The heating element H 2 will stop the heating operation.
再者，當第二位址信號A(2)持續為相對邏輯高電位且第一選擇信號C(1)亦為相對邏輯高電位，即V(A(2))=1、V(C(1))=1之情況下，第四開關元件M4 將導通，使得第二位址信號A(2)可通過第四開關元件M4 控制第五開關元件M5 導通，進而選擇性地使電壓信號P(1)提供電能至第一加熱元件H1 。同理，驅動第一加熱元件H1 加熱，並使流經第一加熱元件H1 之墨水經由對應之噴孔噴塗至列印載體上，以順利完成噴墨的動作。在此同時，由於第一共接點211上之電能V(Ka )係為一相對邏輯高電位，即V(Ka )=1，或者，第一位址信號A(1)或第三位址信號A(3)其中之一位址信號為相對邏輯高電位時，即V(A(1))=1或V(A(3))=1，將分別使得第二噴墨單元22之第八開關元件M8 、第六開關元件M6 或第七開關元件M7 導通，因此殘留於第二共接點221上之電能V(Kb )可經由第八開關元件M8 、第六開關元件M6 或第七開關元件M7 其中之一開關元件被導引至接地端23，進而使第二共接點221上之電能V(Kb )降至0V，且使第十開關元件M10 回復到未動作之初始狀態。Furthermore, when the second address signal A(2) continues to be relatively logic high and the first selection signal C(1) is also relatively logic high, ie V(A(2))=1, V(C( 1)) = 1 in the case of the fourth switching element M 4 will be turned, so that the second address signal A (2) through the fourth switching element M 4 M 5 controls the fifth switching element is turned on, and thus selectively voltage signal P (1) providing a first electrical energy to the heating element H 1. Similarly, the first heating element H 1 is driven to heat, and the ink flowing through the first heating element H 1 is sprayed onto the printing carrier via the corresponding orifice to smoothly complete the inkjet operation. At the same time, since the electric energy V(K a ) on the first common contact 211 is a relatively logic high potential, that is, V(K a )=1, or the first address signal A(1) or the third When one of the address signals A(3) is relatively logic high, that is, V(A(1))=1 or V(A(3))=1, the second inkjet unit 22 will be caused, respectively. The eighth switching element M 8 , the sixth switching element M 6 or the seventh switching element M 7 are turned on, so that the electric energy V(K b ) remaining on the second common contact 221 can be via the eighth switching element M 8 , One of the six switching elements M 6 or the seventh switching element M 7 is guided to the ground terminal 23, thereby reducing the electric energy V(K b ) on the second common contact 221 to 0V, and making the tenth switch Element M 10 returns to the initial state of no action.
同理，當第二位址信號A(2)及第二選擇信號C(2)再度轉變為相對邏輯高電位且第一選擇信號C(1)轉變為相對邏輯低電位時，第二共接點221上之電能V(Kb )係為相對邏輯高電位，即V(Kb )=1，將使得第一噴墨單元21之第三開關元件M3 導通，或者，第一位址信號A(1)或第三位址信號A(3)其中之一位址信號為相對邏輯高電位時，第一開關元件M1 或第二開關元件M2 導通，此時，殘留於第一共接點211上之電能V(Ka )可經由第三開關元件M3 、第一開關元件M1 或第二開關元件M2 其中之一開關元件被導引至接地端23，使得第一共接點211上之電能V(Ka )降至0V，並使第五開關元件M5 截止，且第一加熱元件H1 無法被驅動加熱，藉此達到確保同一時間內僅有第二噴墨單元22或第一噴墨單元21之任單一個噴墨單元，進行加熱之作動。Similarly, when the second address signal A(2) and the second selection signal C(2) are again converted to a relatively logic high level and the first selection signal C(1) is converted to a relatively logic low level, the second common connection The electric energy V(K b ) at the point 221 is a relatively logic high potential, that is, V(K b )=1, which will cause the third switching element M 3 of the first ink ejection unit 21 to be turned on, or the first address signal. when A (1) or the third address signal A (3) wherein one of the address signal is relatively logic high, the first switching element or the second switching element M 1 M 2 is turned on, at this time, remaining in the first co The electric energy V(K a ) on the contact 211 can be guided to the ground end 23 via one of the third switching element M 3 , the first switching element M 1 or the second switching element M 2 , so that the first total The electric energy V(K a ) at the contact 211 is lowered to 0V, and the fifth switching element M 5 is turned off, and the first heating element H 1 cannot be driven and heated, thereby ensuring that only the second ink ejection is performed at the same time. The unit 22 or the single ink jet unit of the first ink jet unit 21 performs heating operation.
由上述可知，根據本案之構想，當噴墨單元組2於順向列印之狀態時，第一噴墨單元21將先進行噴墨之作動，而後第二噴墨單元22再進行噴墨之作動。反之，當噴墨單元組2於逆向列印之狀態時，第二噴墨單元22將先進行噴墨之作動，而後第一噴墨單元21再進行噴墨之作動。As can be seen from the above, according to the concept of the present invention, when the ink jet unit group 2 is in the state of being printed in the forward direction, the first ink ejecting unit 21 will perform the ink ejecting operation first, and then the second ink ejecting unit 22 will perform the ink ejecting. Actuate. On the other hand, when the ink jet unit group 2 is in the reverse printing state, the second ink jet unit 22 will perform the ink jet operation first, and then the first ink jet unit 21 performs the ink jet operation.

於一些實施例中，噴墨陣列3可接收N個位址信號A，其中N為整數，例如但不限於N=16，也就是說，噴墨陣列3可接收16個位址信號，且時序n=1~16。因此當n=1時，複數個位址信號即為A(n-1)=16、A(n)=1與A(n+1)=2，而當n=16時，複數個位址信號即為A(n-1)=15、A(n)=16與A(n+1)=1，藉此分別控制噴墨陣列3之每一噴墨單元組，以產生加熱之作動 。In some embodiments, the inkjet array 3 can receive N address signals A, where N is an integer, such as but not limited to N = 16, that is, the inkjet array 3 can receive 16 address signals, and timing n=1~16.
