The specific embodiment
Consumable container of the present invention both can be mounted in the print cartridge on the ink-jet printer, also can be mounted in cartridge or carbon dust tube on laser printer or duplicator, facsimile machine, the all-in-one, below in conjunction with each embodiment the present invention was elaborated.
Consumable chip and method of work first embodiment thereof:
The consumable chip of present embodiment is the ink box chip that is installed in cartridge of ink-jet printer, and it has a substrate, and the one side of substrate is provided with a plurality of electric contacts as communication unit, is used for being connected with the electric contact of ink-jet printer.Certainly, if be wireless telecommunications between ink-jet printer and the consumable chip, then communication unit is the antenna that is used for wireless telecommunications.Another side at substrate is provided with the electronic module that is connected with electric contact, and the electrical schematic diagram of electronic module is as shown in Figure 5.
Electronic module is provided with control module 41, interface unit 42, memory and clock signal detection circuit, and wherein memory comprises nonvolatile memory 43 and volatile memory 44.
Interface unit 42 is connected with electric contact, receives the signal of telecommunication from electric contact.Interface unit 42 is provided with filter circuit, delay circuit etc., and the signal of telecommunication that is received is carried out processing such as filtering, time-delay.
Control module 41 is used for the signal that reception interface unit 42 receives; And what judge that ink-jet printer sends according to the signal that receives is any order; Command execution according to ink-jet printer is operated accordingly, as writing data to nonvolatile memory 43 or volatile memory 44, reading data that are stored in nonvolatile memory 43 or the volatile memory 44 etc.Certainly, control module 41 needs to receive the clock signal that ink-jet printer sends, and under this clock signal, carries out work, guarantees the communication synchronization with ink-jet printer.
Nonvolatile memory 43 is EEPROM (electrically erasable read-only memory) or FLASH (flash memory) etc.; The relevant data of its storage print cartridge and ink comprise and hold in ink color, the print cartridge ink surplus etc. in print cartridge model, suitable ink-jet printer model, the print cartridge.
Volatile memory 44 is memories such as SRAM, and its reading and writing data data are very fast, but the data of storing after the power down will lose, and is used for storing the data that ink-jet printer writes to chip temporarily.Because ink-jet printer writes the rapid speed of data; In the nonvolatile memory 43 that writes direct after the control module 42 reception data; May cause data to write fully too slowly because of write data speed to nonvolatile memory 43; Therefore after control module 42 receptions need be written to the data of nonvolatile memory 43; The data that earlier needs write are written in the volatile memory 44, treat that the ink-jet printer stops after chip carries out read-write operation, and the data that control module 42 will be stored in volatile memory 44 write back in the nonvolatile memory 43.
Clock signal detection circuit is formed by resistance R 1, FET Q1, capacitor C 1, Schmidt trigger G1 and with door F1, and an end of capacitor C 1 is connected with power supply VCC through resistance R 1, and the power supply that provides of reception power supply VCC.In the present embodiment, power supply VCC is the dc source that is provided by ink-jet printer, and ink-jet printer provides dc source through the power contact in a plurality of electric contacts of consumable chip, and to power supplies such as interface unit 42, control module 41, nonvolatile memories 43.The end that capacitor C 1 is connected with resistance R 1 is the high level end, and its voltage is higher, the other end ground connection of capacitor C 1.
FET Q1 is the switching device of present embodiment, and its grid is a control end, receives the clock signal SCK of ink-jet printer output, and by clock signal SCK control break-make.The drain electrode of FET Q1 and source electrode are connected to the high level end and ground of capacitor C 1 respectively.Because FET Q1 is a N type FET, conducting when clock signal SCK is high level, the electric current of power supply VCC output directly flows to ground through FET Q1, and capacitor C 1 can not charged, and is in discharge condition.When clock signal SCK was low level, FET Q1 ended, and power supply VCC is to capacitor C 1 charging.
Capacitor C 1 is the energy-storage travelling wave tube of present embodiment, and whether present embodiment utilizes the charging interval of capacitor C 1 to calculate clock signal SCK does not have pulse signal to occur in the given time.
The high level end of capacitor C 1 is connected to the input of Schmidt trigger G1; The output of Schmidt trigger G1 is connected to an input with door F1; Receive the chip operation enabling signal CL that control module 41 is exported with another input of door F1, export signals to control module 41 with the output of door F1.
Referring to Fig. 6, when ink-jet printer and chip communication, at first power supply VCC is provided to chip, pulse clock signal is provided then, therefore before clock signal SCK was pulse signal, power supply VCC had been a high level.And; Ink-jet printer stops after chip sends order; At first clock signal SCK being changed to low level signal, is single level signal within a certain period of time promptly, pass through the short time then after; Power supply VCC just becomes low level signal, is changed to low level from clock signal SCK and becomes the summation that the low level time is T1 and T2 to power supply VCC.
The chip operation enabling signal CL of control module 41 outputs is the order output that control module 41 sends according to ink-jet printer; When ink-jet printer when chip sends code and is the order of 0x6FC0; Circuit in the chip will be activated and start working, like input/output port startup, internal counter, counter startup work etc.Therefore; Control module 41 receives the order of the expression chip circuit work startup of ink-jet printer transmission; Promptly send the chip operation enabling signal, just chip operation enabling signal CL is changed to high level, and high level signal is maintained to power supply VCC and becomes till the low level.
Ink-jet printer is behind chip power supply, and power supply VCC is a high level, and this moment, clock signal SCK was a low level signal, and FET Q1 ends, capacitor C 1 charging, and the voltage that capacitor C 1 high level end A is ordered is upgraded to high level from low level.Meanwhile, ink-jet printer does not send the order that starts chip operation, and chip operation enabling signal CL is a low level.
When ink-jet printer was pulse signal to chip clock signal SCK, FET Q1 replaced break-make: when clock signal SCK is high level, and FET Q1 conducting, the electric current of power supply VCC directly flows to ground, capacitor C 1 discharge, the A point voltage descends; When clock signal SCK was low level, FET Q1 ended, and capacitor C 1 is charged once more, and the A point voltage rises.Therefore, when the clock signal SCK of ink-jet printer output pulse, capacitor C 1 is charge and discharge repeatedly, and is visible from Fig. 6, and this moment, the A point voltage was lower all the time.
After the clock signal SCK of ink-jet printer output remained low level signal, capacitor C 1 was able to long-time charging, and the A point voltage slowly rises, and passing through the A point voltage from last pulse signal of clock signal SCK, to rise to the time that peak consumes be T1.
The voltage that forms behind the voltage process Schmidt trigger G1 that A is ordered is shown in the voltage waveform that B is ordered; Have only when the A point voltage is higher than certain value; The B point voltage is a high level signal; Other times B point voltage is a low level signal, guarantee like this to import with the door F1 signal have only high level signal and low level signal two states.
Voltage that chip operation enabling signal CL and B are ordered through with door F1 computing after, with the waveform of door F1 output shown in C point waveform, its high level lasting time be the A point voltage reach behind the peak become low level to power supply VCC before, the duration is T2.With the high level signal of door F1 output data conversion storage signal just, control module 41 is when receiving the data conversion storage signal, in data conversion storage to the nonvolatile memory 43 that is stored in the volatile memory 44.
Like this, chip utilizes ink-jet printer to stop to carry out read-write operation to chip, and just clock signal SCK is behind the single low level signal; And power supply VCC still remains in time period of high level signal data conversion storage; Can avoid like this power supply unit is set on chip, and the power supply VCC voltage that ink-jet printer provides can remain high level signal, the situation that voltage slowly descends can not occur; Guarantee intactly unloading of data, avoid loss of data.
It is thus clear that ink-jet printer is after chip sends data, chip at first is temporarily stored in the data that receive in the volatile memory 44; And detect in the given time by clock signal detection circuit whether clock signal is single level signal; In the present embodiment, the scheduled time is T1, and is definite by the charging interval of capacitor C 1; And single level signal is a low level signal, representes that promptly ink-jet printer stops to carry out read-write operation to chip.After clock signal detection circuit judges to be always single level signal in the given time, export the data conversion storage signal, control module will be stored in the data conversion storage of volatile memory to nonvolatile memory.
Consumable chip and method of work second embodiment thereof:
Present embodiment has substrate; Substrate is provided with electric contact and electronic module; The electrical schematic diagram of electronic module is as shown in Figure 7; Have control module 51, interface unit 52, memory etc., and be provided with the clock signal detecting unit, wherein memory comprises nonvolatile memory 53 and volatile memory 44.
In the present embodiment; The clock signal detecting unit constitutes by resistance R 2, capacitor C 2, FET Q2, Schmidt trigger G2 and with door F2; FET Q2 is a P type FET, and its grid receives the clock signal SCK that ink-jet printer provides, and source electrode connects power supply VCC through resistance R 2; Drain electrode is connected to the high level end of capacitor C 2, the other end ground connection of capacitor C 2.
The high level end of capacitor C 2 is connected to the input of Schmidt trigger G2; The output of Schmidt trigger G2 is connected to an input with door F2; Receive the chip operation enabling signal that control module 51 is exported with another input of door F2, export signals to control module 51 with the output of door F2.
FET Q2 is as the switching device of present embodiment, conducting when clock signal SCK is low level, and power supply VCC is to capacitor C 2 chargings as the energy storage source electrode; When clock signal SCK was high level, FET Q2 ended, capacitor C 2 discharges; Its high level terminal voltage descends; Therefore when clock signal SCK was pulse signal, capacitor C 2 constantly discharged and recharged, and the input terminal voltage of Schmidt trigger G2 is lower.
When clock signal SCK was low level for a long time, FET Q2 kept conducting state, and capacitor C 2 is in charged state, and the high level terminal voltage slowly rises, so the high level terminal voltage oscillogram of capacitor C 2 is identical with A point oscillogram shown in Figure 6.The voltage oscillogram of Schmidt trigger G2 output is also identical with B point oscillogram shown in Figure 6.In addition; The application's chip operation enabling signal CL also is a control module 51 according to receiving code that ink-jet printer sends is that the order of 0x6FC0 becomes high level signal; Therefore with the voltage waveform of door F2 output and first embodiment in voltage waveform with door F1 output identical, promptly remain in the scheduled time in clock signal and export the data conversion storage signal low level the time with door.
Like this; After chip receives the data of ink-jet printer output; The data that receive are temporarily stored in the volatile memory 54, after control module 51 receives the data conversion storage signal, in the data conversion storage that is stored in volatile memory 54 to nonvolatile memory 53.
Consumable chip and method of work the 3rd embodiment thereof:
Present embodiment also is provided with substrate; Substrate is provided with electric contact and electronic module; The electrical schematic diagram of electronic module is as shown in Figure 8, and it has control module 61, interface unit 62, memory etc., and wherein memory comprises nonvolatile memory 63 and volatile memory 64; Electronic module also is provided with clock signal detection circuit, is produced circuit 66 and is constituted with door F3 by counter 65, reference clock signal.
Reference clock signal produces circuit 66 and is used to produce reference clock signal, and this reference clock signal is a pulse signal, and frequency is higher than the frequency of the clock signal SCK that ink-jet printer provides.Receive reference clock signal with the input of door F3, another input receives the chip operation enabling signal CL that control module 61 sends, and output is to counter 65 output signals.
Store preset count value in the counter 65, this count value is predetermined value.Simultaneously, can set counter 65 and promptly reset after clock signal SCK is pulse signal receiving, just carry out clear operation.And counter 65 whenever receives a pulse signal of reference clock signal and promptly counts once.
Like this, when clock signal SCK is pulse signal, counter 65 will constantly be carried out clear operation, and the count value of counter 65 can be very not big.In case clock signal SCK is single level signal for a long time; Low level signal for example; The count value of counter 65 can't be by zero clearing, and the count value of count value 65 is bigger, when count value during greater than predetermined value; Represent that promptly the clock signal SCK that ink-jet printer sends does not comprise pulse signal for a long time, promptly sends the data conversion storage signal to control module 61.
Through suitable count value is set, can guarantee that counter 65 judges in the given time accurately whether clock signal SCK is always single level signal.
It is thus clear that; Ink-jet printer is after the data that the chip transmission need write; Chip at first with storage in volatile memory 64, and clock signal is detected, after having only the clock signal of judgement clock signal being always single level signal in the given time by clock signal detection circuit; Send the data conversion storage signal, control module 61 will be stored in data conversion storage to the nonvolatile memory 63 of volatile memory 64.
Because the counting of counter 65 is accurate, the scheme of present embodiment can guarantee that clock signal detection circuit work is more accurate, sensitive.
Certainly, the 3rd embodiment can also do following change: clock signal detection circuit is provided with timer, timer receive clock signal SCK, and storing predetermined timing time in the timer, the just scheduled time.Timer receives pulse signal and promptly resets, and timing time recomputates, and timing always when not receiving pulse signal is longer than the scheduled time when timing time and is promptly sent the data conversion storage signal.Like this, having only clock signal SCK is pulse signal, and the actual timing time of timer is no longer than the scheduled time, and when clock signal SCK is single level signal, timing time will be longer than the scheduled time, and control module is promptly carried out the data conversion storage operation.
