In addition, when control signal S1 is low, when PS1 activation and fuse equipment Fuse1 when melting down, PS1 sees through resistance R 1 and produces an electric current and flow to transistor Q
f1, when this moment, electric current and control signal S1 were high, Q
b1 electric current that flows through when being switched on is by contrast little a lot, therefore just can reduce Q on circuit design
f1 size is saved circuit area.
Please refer to Fig. 3.Fig. 3 is for driving the signal waveforms of Fig. 2 ink gun.31 is write state, its action for recorded information to tape deck, this moment, control signal S1 was high, the signal of PS1～PS4 is " 0,1,0,1 " in regular turn.33 expressions are write state at this moment on the oscillogram, and the state on the DOL Data Output Line S2 is high, but at this moment the phase is not considered.The signal of PS1～PS4 is " 0,1,0,1 ", so the recorded information on Fuse1～Fuse4 is " 1,0,1,0 " in regular turn.32 for reading state, and this moment, control signal S1 was low, and activation PS1～PS4 then can read the information of " 1,0,1,0 " at DOL Data Output Line S2 in regular turn, conforms to the recorded information of Fuse1～Fuse4.
Please refer to Fig. 4.Fig. 4 is for using a printer system of ink gun of the present invention.Controller 42 on the printer is when receiving print data, see through data wire 47 and send print data to driver of ink-jet head 43, this moment, driver of ink-jet head 43 was decoded into address signal and pel selection signal with print data, see through address wire 48A and pel respectively and select line 48B to be sent to ink gun nozzle array circuit 44, carry out one and print action.
When ink gun 41 just and during printer 40 (not comprising ink gun) successful connection, controller 42 on the printer sees through a control line 46 and requires the writing circuit 45 on the ink gun to see through the recognition data that a DOL Data Output Line 49 is passed ink gun back, then controller 42 can distinguish whether this ink gun 41 is compatible with printer 40 according to the ink gun recognition data of passing back, but if compatibility then printer normal operation, if incompatible then send the error message notification user, and stop action.When printer prints, for grasping the surplus of ink cartridges ink inside, therefore need the accurate position of ink record and can offer the user, the user can be changed where necessary.The method of the accurate position of ink record is as follows: when the controller on the printer 42 when the quantity of ink of detecting ink gun ejection reaches certain value, this moment, controller 42 required write activity through 46 pairs of writing circuits 45 of control line, the data that will write down are sent to driver of ink-jet head 43, being decoded into pel selects signal to be sent to writing circuit 45 (at this moment for avoiding causing the mistake of ink gun generation printing action, address signal can be made as 0 entirely), data are write.
