The specific embodiment
The circuit framework of prior art is to utilize address signal to drive heating resistor, so address signal needs bigger driving force could drive radiating circuit; In addition, between the heating resistor of address signal and radiating circuit, added a field-effect transistor as gauge tap, transistor has substrate effect (body effect), makes that the accurate position of driving that radiating circuit received is lower, and causes bigger ink-jet to postpone.Therefore the present invention proposes ink injection print-head control circuit, postpones in order to reduce ink-jet, promotes driving accurate position, and can promote inkjet performance.Below just the present invention is described with embodiment.
What must illustrate is that the explanation of following each embodiment is graphic with reference to what add, can be in order to the specific embodiment of implementing in order to illustration the present invention.The direction term that the present invention mentioned, for example " on ", D score, " preceding ", " back " etc., only be direction with reference to annexed drawings.Therefore the direction term that uses is to be used for explanation, but not is used for limiting the present invention.
Fig. 3 A illustrates the circuit box schematic diagram into the ink injection print-head control circuit of the embodiment of the invention, and can contain many group ink injection print-head control circuits in an ink-jet printing head ink output unit (for example print cartridge) usually.Please refer to Fig. 3 A, this circuit comprises at least one nozzle radiating circuit 301 and nozzle countdown circuit 302.Nozzle radiating circuit 301 comprises switch SW 301 and heating resistor R301 at least, wherein switch SW 301 and heating resistor R301 are serially connected with between power supply potential P and the preset potential VSS, in this embodiment, for example heating resistor couples power supply potential P, switch SW 301 couples between heating resistor and the preset potential VSS, and preset potential for example is an earthing potential.Nozzle countdown circuit 302 electric property couplings (" electric property coupling " is called for short in the present invention: " coupling ") are in nozzle radiating circuit 301, and signal SEL and address signal ADD are selected in reception.When address signal ADD activation (enable) and when selecting signal SEL activation, control nozzle radiating circuit 301 carries out ink-jet with power supply potential P when high potential (power supply potential) actuating switch SW301 to drive heating resistor R301.
Fig. 3 B～3D is several examples with power supply potential P actuating switch SW301, in following examples, all switches all with the N transistor npn npn as an example, knowing this operator should know, switch is except the N transistor npn npn, still can the P type, the mode equivalence of multiplexer, transmission lock, relay (Relay) or the like implements, so the invention is not restricted to this.Fig. 3 B, for example between power supply potential P and switch SW 301 with electric property coupling switch SW 302, when address signal ADD activation and selection signal SEL activation, actuating switch SW302, make the control end (gate pole of N transistor npn npn just) of switch SW 301 receive power supply potential P, therefore the effect that can accomplish quick conducting.
The difference of Fig. 3 C and Fig. 3 B is that Fig. 3 C has been connected in series an impedor R302 to preset potential VSS more under switch SW 302.Fig. 3 D has disclosed another kind of embodiment with power supply potential P actuating switch SW301.In Fig. 3 D, power supply potential P sees through the control end (gate pole of N transistor npn npn just) that impedor R302 is couple to switch SW 301, switch SW 302 have been connected in series impedor R302 beneath in addition more, when address signal ADD not activation or select signal SEL as yet not during activation as yet, switch SW 302 is to be in conducting state; When address signal ADD activation and selection signal SEL activation, gauge tap SW302 makes the control end of switch SW 301 by (not conducting), and just the gate pole of N transistor npn npn receives power supply potential P, therefore the effect that can accomplish quick conducting.
What deserves to be explained is, though ink injection print-head control circuit has been depicted some possible kenels in the foregoing description, but knowing this operator should know, each manufacturer is all different for the design of nozzle radiating circuit 301 and nozzle countdown circuit 302, and therefore application of the present invention is when being not restricted to the possible kenel of this kind.In other words, so long as the switch SW 301 of nozzle radiating circuit 301 and heating resistor R301 are serially connected with between power supply potential P and the preset potential VSS, and when address signal ADD activation and selection signal SEL activation, nozzle countdown circuit 302 control nozzle radiating circuits 301 are with power supply potential P when high potential (power supply potential) actuating switch SW301, carrying out the ink-jet action to drive heating resistor R301, has been to have met spiritual place of the present invention just.
Next will enumerate several embodiment so that present technique field person can implement the present invention easily.
Fig. 4 A and Fig. 4 B illustrate the circuit diagram for the ink injection print-head control circuit of being implemented according to embodiment of the invention Fig. 3 A.Please refer to Fig. 4 A, the nozzle radiating circuit 301 of this circuit be with transistor Q401 as switch SW 301, and resistance H41 is as heating resistor R301; The nozzle countdown circuit 302 of this circuit is with transistor Q402, Q403, Q404 and Q405 and resistance R 401, R402, R403, R404 and R405 as an example, and its relation of coupling is as Fig. 4 A.
When selecting signal SEL and all not activations of address signal ADD (supposing that in this embodiment enabled status is a logical one), transistor Q402 is by (not conducting), so also not conducting of transistor Q401, does not pass through so heating resistor H41 does not have electric current.When selecting signal SEL activation, but address signal ADD is not as yet during activation, just represent that printer side chooses the print cartridge that comprises this embodiment ink injection print-head control circuit this moment, but be not to choose specific ink injection print-head control circuit (because may contain many group ink injection print-head control circuits in the print cartridge, be coupled to corresponding address signal ADD respectively), this moment, transistor 0403 ended with Q405, made Q402 end; Because select signal SEL activation to make the Q404 conducting, the gate pole of Q401 is pulled to electronegative potential and ends, nozzle radiating circuit thereby can ink-jet.When selecting not activation of signal SEL, but during address signal ADD activation, represent that printer side do not choose the print cartridge that comprises this embodiment ink injection print-head control circuit this moment, and this moment, transistor Q402 and Q404 ended, therefore yet not conducting of transistor Q401 is not passed through so heating resistor H41 does not have electric current.When selecting signal SEL and address signal ADD all during activation, this moment transistor Q403 and Q405 conducting, transistor Q402 receives selection signal SEL that transistor Q403 passed and conducting; Transistor Q404 is because selection signal dividing point is dragged down current potential by transistor Q405 and ends; Because the Q402 conducting makes power supply potential P pour into the gate pole of transistor Q401 (as power supply potential P during at high potential), thereby the quick conducting of transistor Q401, make electric current flow through heating resistor H41, and then heating ink is to carry out ink-jet.What must illustrate is, when selecting signal SEL and address signal ADD all during activation, as power supply potential P electronegative potential (not providing enough power supplys or voltage) to this nozzle radiating circuit, the gate pole of transistor Q401 can conducting, so electric current can not flow through heating resistor H41 and comes heating ink to carry out ink-jet.
