See Fig. 1, existing a kind of color inkjet printer has the supporting plate that the ink-jet printer shown in casing 11, Fig. 1 eliminates casing 11.Be provided with the movement 12 of ink-jet printer in casing 11, and be provided with a slide bar, print word car 14 and move back and forth along slide bar under the drive of motor (invisible in Fig. 1).Print in word car 14 and be provided with keyset (invisible in Fig. 1), keyset is communicated with movement 12 by winding displacement 13.
Print on word car 14 and multiple print cartridge 15 is removably installed, in different print cartridge 15, accommodate the ink of different colours.The structure of print cartridge 15 as shown in Figure 2.Print cartridge 15 has housing 16, and housing 16 surrounds the cavity holding ink, and the lower end of cavity is provided with ink outlet port 17, and the ink in cavity is flowed out by ink outlet port 17, and to printing the confession tattooing needle ink supply of word car 14.
The outer wall of print cartridge 15 housing 16 is provided with chip piece 18, and chip 18 has substrate, and the side of substrate is provided with multiple electric contact 19, for being electrically connected with keyset.The opposite side of substrate is provided with the electronic module (invisible in Fig. 2) be electrically connected with electric contact 19.
See Fig. 3, electronic module is provided with control unit 21, memory 22, interface unit 25 and power supply unit 27, wherein interface unit 25 is for being electrically connected with electric contact 19, control unit 21 receives the information from ink-jet printer by interface unit 25, and sends to the information of ink-jet printer to be sent by interface unit 25 by needing.Control unit 21 comprises analog circuit and digital circuit, and analog circuit comprises clock circuit, drive circuit etc. for generation of clock signal, and digital circuit comprises single-chip microcomputer or logic circuit etc.
Memory 22 comprises nonvolatile memory 23 and volatile memory 24, nonvolatile memory 23 is generally EEPROM or FLASH, it stores the information relevant to print cartridge, comprise variable information and fixed information, variable information is the information that can constantly change with printing, as ink surplus, print the information such as duration, print paper quantity, fixed information is the information that can not change with printing, as cartridge model, applicable ink-jet printer model, ink color etc.Volatile memory 24 is the memories such as SRAM, and its read or write speed is very fast, for storing the data that ink-jet printer writes to consumable chip temporarily.After volatile memory 24 power down, its data stored will be lost, and therefore need the data conversion storage stored in time in nonvolatile memory 23 during power down.
Power supply unit 27 is that electric capacity or rechargeable battery etc. are chargeable and have the device of energy storage function, when ink-jet printer is to chip power supply, power supply unit 27 store electrical energy, ink-jet printer stops after chip power supply, power supply unit 27 discharges and powers to control unit 21, memory 22, now, the data conversion storage that volatile memory 24 temporarily stored of control unit 21 is in nonvolatile memory 23.
After print cartridge 15 is installed to the printing word car 14 of ink-jet printer, ink-jet printer powers on to chip 18, and reads the data that are stored in chip 18 memory, judges whether print cartridge 15 model is suitable, residual ink amount whether abundance etc. in print cartridge 15.Only have and judge that print cartridge 15 model is suitable and after having sufficient ink in print cartridge 15, ink-jet printer could perform print job.
Because existing chip needs when power down the electric energy using power supply unit 27 to provide to carry out the unloading of data, and data conversion storage needs certain hour, in data conversion storage process, the voltage that power supply unit 27 exports will constantly reduce, once brownout, just cannot ensure the work of volatile memory 24, have influence on the integrality of unloading data, the situation of loss of data may occur.
But, existing part ink-jet printer is with ink box chip communication process, there will be and repeatedly stop after ink box chip 18 power supply, through the situation of powering to ink box chip can be continued again after a period of time, if there is the of short duration power down of repeatedly different interval, as only having 1 millisecond of even shorter time, control unit 21 all needs by the data conversion storage of volatile memory 24 in nonvolatile memory 23, then the possibility write time is inadequate.In addition because twice power down time interval also has and longly have short, the voltage of power supply unit 27 also can be made all to be not fully filled at every turn and to affect the reliability of write back operations.
In order to judge that ink-jet printer stops the time span of powering to ink box chip 18, existing a part of ink box chip arranges power-fail detection circuit and detects or arrange counter to calculate the time span of stopping power supply by selection RC delays.That a kind of counter that utilizes is to detect the chip of power down time as shown in Figure 4, the electronic module of this chip has control unit 31, interface unit 32, memory etc., wherein memory comprises nonvolatile memory 33 and volatile memory 34, electronic module be also provided with counter 35, reference clock signal produce circuit 36 and with door F3 etc.
Reference clock signal produces circuit 36 for generation of reference clock signal, this reference clock signal is pulse signal, it selects chip internal master clock signal, this clock signal is for carrying out the data that export ink-jet printer and clock signal SCK samples, therefore the frequency of clock signal SCK that frequency provides far above ink-jet printer.Receive reference clock signal with an input of door F3, the chip operation enabling signal CL that another input reception control unit 31 sends, output outputs signal to counter 35.
Store default count value in counter 35, and namely setting counter 35 resets, and namely performs clear operation receiving after clock signal SCK is pulse signal.Further, namely the pulse signal that counter 35 often receives reference clock signal counts once.
Like this, when the time that ink-jet printer to be powered to ink box chip or stopped power supply is shorter, clock signal SCK is respectively pulse signal or the shorter signal of single level duration, and counter 35 constantly will perform clear operation, and the count value of counter 35 can not be very large.Once ink-jet printer stops powering to ink box chip for a long time, clock signal SCK is single level signal, such as low level signal for a long time, and the count value of counter 35 cannot be cleared, and the count value of count value 35 is larger.When count value is greater than default count value, counter 33 sends data conversion storage signal to control unit 31.
But, reference clock signal produces circuit 36 to be needed to produce the clock signal of very high frequency and exports counter 35 to, generation due to clock signal is realized by the speed-sensitive switch of switching device and discharge and recharge, the higher then current loss of frequency is larger, and clock signal also wants actuation counter and other circuit, the current loss of this respect is larger, needs like this to consume a large amount of electric energy.Because counter 35 stops still will working when powering to ink box chip at ink-jet printer, therefore reference clock signal produces the electric energy that circuit 36 uses electric capacity etc. to provide.If preset long by the detection of power loss time, like this, reference clock signal produces a large amount of electric energy of the consumption in operation electric capacity of circuit 36, causes the brownout that in data conversion storage process, electric capacity exports, affects the work of data conversion storage.If the detection of power loss time is preset too little, then power down all must need write-back at every turn, for the situation that power-on time is too short, the voltage of power supply unit 27 can be made to be not fully filled, when ink-jet printer stops powering to ink box chip, control unit 21 needs by the data conversion storage of volatile memory 24 to nonvolatile memory 23, because power supply unit 27 brownout, and makes unloading error in operation.
But, the clock signal provided due to the clock circuit of control unit 31 is for data acquisition and communication, the frequency of this clock signal is generally between 4MHZ to 10MHZ, because this clock signal also will be supplied to the high voltage electricity pump booster circuit of nonvolatile memory 33 as switching pulse signal, do not allow too low.Therefore, existing ink box chip is after ink-jet printer is stopped power supply, and power consumption is very big, is unfavorable for the unloading of data.
See Fig. 5, existing cartridge has housing 41, and housing 41 surrounds the cavity holding carbon dust, and the outer wall of housing is provided with a chip installation position 42, and chip 43 is installed on chip installation position 42.Similar with the chip of print cartridge, the chip 43 of cartridge also has substrate, and substrate is provided with the electric contact 44 as communication unit, for carrying out exchanges data with laser printer.And, the opposite side of substrate is provided with the electronic module be electrically connected with electric contact 44, electronic module also arranges interface unit, control unit and nonvolatile memory, volatile memory, power supply unit etc., for the same reason, chip 43 also can exist laser printer stop power supply after data conversion storage to cross Cheng Qian power consumption excessive, affect the integrality of data conversion storage.
In addition, the imaging devices such as existing most of duplicator, facsimile machine or all-in-one are all removably provided with cartridge or carbon starch cylinder as consumable container, consumable container has the cavity holding carbon dust, and chip is set on the outer wall of consumable container, also there is the problem identical with the chip of print cartridge in these chips, namely in volatile memory before nonvolatile memory unloading data, chip consume electric energy too much.

Detailed description of the invention
Consumable container of the present utility model both can be mounted in the print cartridge on ink-jet printer, also can be mounted in the cartridge on laser printer or duplicator, facsimile machine, all-in-one or carbon starch cylinder, below in conjunction with each embodiment, the utility model is described in detail.
Consumable chip embodiment:
The consumable chip of the present embodiment is the ink box chip being arranged on cartridge of ink-jet printer, and it has one piece of substrate, and the one side of substrate is provided with the multiple electric contacts as communication unit, for being connected with the electric contact of ink-jet printer.Certainly, if between ink-jet printer and consumable chip be radio communication, then communication unit is the antenna for radio communication.Be provided with the electronic module be connected with electric contact at the another side of substrate, the electrical schematic diagram of electronic module as shown in Figure 6.
Electronic module is provided with digital circuit 60, analog circuit and memory, and memory comprises nonvolatile memory 61 and volatile memory 62.Digital circuit 60 comprises the control chips such as single-chip microcomputer, for communicating with ink-jet printer 70, and the data-signal SDA exported as reception ink-jet printer 70 and clock signal SCL etc.Further, what control chip also judged that ink-jet printer 70 sends according to the signal received is any order, performs operate accordingly according to the order of ink-jet printer 70.Digital circuit 60 also can be made up of logic circuit, namely forms special IC.
Memory comprises nonvolatile memory 61 and volatile memory 62, and nonvolatile memory 61 and volatile memory 62 are all electrically connected with digital circuit 60, and by digital circuit 60 access control.Nonvolatile memory 61 is EEPROM(electrically erasable read-only memory) or FLASH(flash memory) etc., it stores the relevant data of print cartridge and ink, to comprise in cartridge model, applicable ink-jet printer model, print cartridge containing ink color, print cartridge ink surplus etc.Digital circuit 60 can export order such as order DIN/DOUT and read write command WR/RD etc. to nonvolatile memory 61 OPADD ADDRESS, numeral write.
Volatile memory 62 is the memories such as SRAM, and its reading and writing data data are very fast, but the data stored after power down will be lost, for storing the data that ink-jet printer 70 writes to chip temporarily.Because ink-jet printer 70 writes the speed of data, if digital circuit 60 is write direct after receiving data in nonvolatile memory 61, may because causing data to write completely too slowly to nonvolatile memory 61 write data speed, therefore after digital circuit 60 receives the data needing to be written to nonvolatile memory 61, first will the data of write be needed to be written in volatile memory 62, after ink-jet printer 70 stops carrying out read-write operation to chip, the data being stored in volatile memory 62 write back in nonvolatile memory 61 by digital circuit 60.
Analog circuit comprises the first analog circuit 64 and the second analog circuit 65, the voltage that ink-jet printer 70 exports is after diode D1, charge to electric capacity C1, and form supply voltage VCC, supply voltage VCC powers to the first analog circuit 64 after FET Q1.In addition, the voltage that ink-jet printer 70 exports is powered directly to the second analog circuit 65.In the present embodiment, electric capacity C1 is power supply unit, charges, and discharge after ink box chip power down when ink-jet printer 70 pairs of ink box chips are powered.
First analog circuit 64 has electrify restoration circuit, voltage and current reference circuit, the first clock circuit, after electrify restoration circuit powers on for ink-jet printer 70 pairs of ink box chips, first analog circuit is resetted, voltage and current reference circuit for generation of reference voltage signal and reference current signal, for other circuit modules.First clock circuit for generation of high frequency clock signal clk and export digital circuit 60 to, for digital circuit 60 as operating clock signals.The clock signal clk exported due to the first clock circuit needs to work for digital circuit 60, and therefore this clock signal is high frequency clock signal, and usually between 4M hertz to 10M hertz, the electric energy that the first analog circuit 64 consumes is higher.
See Fig. 7, be provided with in the second analog circuit 65 power down and power on detection circuit, second clock circuit 71, trigger 72, counter 73 and with or door U3, power down and power on detection circuit are made up of electric capacity C2, delayer U1 and phase inverter U2.When ink-jet printer 70 is powered to ink box chip, its electric current exported after electric capacity C2 filtering, delayer U1 time delay, by POW_ON hold to or door U3 exports high level signal, POW_OFF end output low level signal.Once ink-jet printer 70 stops powering to ink box chip, POW_ON end to or door U3 output low level signal, POW_OFF end export high level signal.
In the application, ink box chip " powers on " and refers to that ink-jet printer 70 exports direct current to ink box chip, and ink box chip " power down " refers to that ink-jet printer 70 stops exporting direct current to ink box chip.
The POW_OFF end of power down and power on detection circuit outputs signal to second clock circuit 71, and when the POW_OFF end of power down and power on detection circuit exports high level signal, second clock circuit 71 starts work, and to counter 73 output pulse signal, counter 73 starts counting.In the present embodiment, the frequency of the clock signal that the frequency of clock signal that second clock circuit 71 exports exports lower than the first clock circuit.Preferably, the frequency of the clock signal that second clock circuit 71 exports is about 50 KHzs, and the electric energy consumed when therefore second clock circuit 71 works is less.
Counter 73 be one can the counter of pre-set count values, and counter 73 will overflow arrive the count value preset at counting after, and export spill over OV to trigger 72, after trigger 72 receives spill over OV, to with or door U3 export data conversion storage signal POD_FLG, with or door U3 export control signal CTL to FET Q1.
In the present embodiment, FET Q1 is switching device, and for controlling the power supply of the first analog circuit 64, as seen from Figure 6, when control signal CTL is high level, FET Q1 turns off, and the first analog circuit 64 power down, therefore the first clock circuit is also stopped power supply immediately.Once control signal CTL is low level signal, FET Q1 conducting, supply voltage VCC is powered to the first analog circuit 64 by FET Q1, and the first clock circuit restarts work.
In second analog circuit, as power down and power on detection circuit detect ink box chip power down after and second clock circuit 71 start, after counter 73 starts counting, before counter 73 count value arrives the count value preset, print cartridge signal re-powers, when namely the print cartridge chip power-down time is shorter, the POW_OFF of power down and power on detection circuit holds output low level signal, second clock circuit 71 quits work, and exports reset signal RSTN to counter 73, and the count value of counter 73 returns to initial value.
The method for writing data embodiment of consumable chip:
When ink-jet printer 70 normally works, direct current is exported to ink box chip, namely dc source is exported to ink box chip by power end, this dc source will directly export power down and the power on detection circuit of the second analog circuit 64 to, now POW_ON end to or door U3 export high level signal, POW_OFF holds output low level signal, with or the control signal CTL that exports of door U3 be low level signal.
Further, the direct current that ink-jet printer exports is powered to electric capacity C1 through diode D1, and forms supply voltage VCC for digital circuit 60.Due to FET Q1 conducting, supply voltage VCC powers to the first analog circuit 64, the first clock circuit work of the first analog circuit 64, produces high frequency clock signal and exports digital circuit 60 to.Digital circuit 60 receives data from ink-jet printer 70, and data is stored in volatile memory 62 temporarily.
Meanwhile, the count value preset of counter 73 is written in counter 73 by digital circuit 60, and counter 73 inverted order counting or positive sequence of starting from scratch from this count value preset count up to this count value preset.
After ink-jet printer 70 stops powering to ink box chip, the POW_ON end of the power down of the second analog circuit 65 and power on detection circuit to or door U3 output low level signal, POW_OFF end exports high level signal to second clock circuit 71, second clock circuit 71 is started working, and to the clock signal of counter 73 output low frequency.After counter 73 receives the low-frequency clock signal of second clock circuit 71 output, often receive a pulse signal and namely count once.
Now, with or door U3 export high level signal, FET Q 1 turns off, and electric capacity C1 cannot power to the first analog circuit 64, therefore the first analog circuit 64 power down, and the first clock circuit also quits work immediately, ink box chip consume electric energy less.
As ink-jet printer 70 stops powering to ink box chip for a long time, then counter 73 overflows after counting up to default count value, spill over is sent to trigger 72, trigger 72 to or the data conversion storage signal POD_FLG that exports of door U3 be high level signal, with or the control signal CTL of door U3 output low level immediately to FET Q1, FET Q1 conducting, the electric current that electric capacity C1 discharges flows to the first analog circuit 64 through FET Q1, first clock circuit restarts work, and exports the clock signal of high frequency to digital circuit 60.Because digital circuit 60 also receives the data conversion storage signal POD_FLG from trigger 72, be therefore written in non-volatile storage 61 with being about to the data be stored in volatile memory 62.
Because the first analog circuit 64 quits work within the time that ink-jet printer 70 stops one after powering to ink box chip, therefore the electric energy of the first analog circuit 64 consumption is less, guarantee that electric capacity C1 has sufficient electric energy to be supplied to digital circuit 60, non-volatile storage 61 and volatile memory 62, meet the need of work of data conversion storage.
If the stopping of ink-jet printer 70 short time is powered to ink box chip, then before the count value of counter 73 does not arrive default count value, power down and power on detection circuit detect that ink box chip restores electricity, then POW_OFF holds output low level signal, second clock circuit 71 quits work, and POW_OFF end exports reset signal to counter 73, and count value is reset to initial count value by counter 73.
Meanwhile, due to POW_ON end to or door U3 export high level signal, with or the control signal CTL that exports of door U3 be low level signal, FET Q1 conducting again, the first analog circuit 64 re-powers, and the first clock circuit restarts work.Like this, stop in the process of powering to ink box chip in ink-jet printer 70 short time, digital circuit 60 can not will be stored in the data conversion storage of volatile memory 62 to nonvolatile memory 61.
At the data conversion storage of volatile memory 62 to nonvolatile memory 61, as electric energy does not still discharge complete by electric capacity C1, then electric capacity C1 can continue release electric energy by nonvolatile memory 61 or second clock circuit 71, until electric energy release is complete, to avoid the charging work affected next time.
