Description
Technical field
The present invention refers to a kind of ink jet unit group of control circuit of ink-ejecting head and ink jet array that is made up of a plurality of these ink jet unit groups of being applicable to especially about a kind of ink jet unit group and ink jet array.
Background technology
At present in the technical development of inkjet printing; Can improve the best of printing resolution and print speed and effective method; Promptly be the quantity that directly increases heating element heater; And in the control of traditional heating element, mainly be to control single corresponding heating element heater through single control contact.
See also Fig. 1, it is the circuit framework sketch map of tradition control heating element heater heating.As shown in Figure 1; Heating element heater 10 is connected between drive controlling end 11 and the switch element 12; And by drive controlling end 11 receptions one voltage signal P; And switch element 12 is connected between control contact 13 and the earth terminal 14, and receives an address signal A by control contact 13, in order to the conducting of gauge tap element 12 with end.For example; When the address signal A that received of control contact 13 is relative logic high potential (High), switch element 12 conductings, at this moment; Voltage signal P provides electric energy to give heating element heater 10, so that the ink on the heating element heater 10 of flowing through is sprayed on the print carrier by the spray orifice (not shown) of correspondence.Otherwise when the address signal A that received of control contact 13 was relative logic low potential (Low), switch element 12 ended, and at this moment, voltage signal P interrupts to heating element heater 10 electric energy being provided, and makes heating element heater 10 stop heating, thereby can't carry out the work of ink-jet.
Yet; Use the method for above-mentioned control heating element heater; If in the time of will increasing heating element heater with raising printing resolution and print speed; Certainly will need to increase the number of control contact,, therefore can make the entire area increase of ink jet crystal plate (not shown) and its production cost also must improve to control each heating element heater respectively.
In addition, in order to reach the purpose that reduces the control contact, utilize control method that the N-MOS element designs the heating element heater running just in response to and gives birth to, but, still must increase the control contact of correspondence if will further increase heating element heater again the time.So the control mode of C-MOS element is used in present more proposition, solve the problem of ink jet crystal plate area increase when the control contact increases, but the manufacturing cost of C-MOS element is high than the manufacturing cost of N-MOS element, so still can't widely uses.
