Description
Technical field
The utility model relates to the printing consumables field, especially relates to a kind of print cartridge and chip of this print cartridge that is installed on the ink-jet printer.
Background technology
Ink-jet printer is common printer, for modern office provides great convenience.Ink-jet printer uses the print cartridge that accommodates ink to spray ink as consumable container to paper, needs literal or the pattern printed with formation on paper.
Referring to Fig. 1, existing a kind of color inkjet printer has casing 11, and ink-jet printer shown in Figure 1 has omitted the supporting plate of casing 11.Be provided with the movement 12 of ink-jet printer in the casing 11, and be provided with a slide bar, print word car 14 and under the drive of motor (invisible among Fig. 1), move back and forth along slide bar.Print in the word car 14 and be provided with keyset (invisible among Fig. 1), keyset communicates through winding displacement 13 and movement 12.
Print on the word car 14 a plurality of print cartridges 15 removably are installed, accommodate the ink of different colours in the different print cartridges 15.The structure of print cartridge 15 is as shown in Figure 2.Print cartridge 15 has housing 16, and housing 16 surrounds the cavity that holds ink, and the lower end of cavity is provided with ink outlet port 17, and the ink in the cavity flows out through ink outlet port 17, and to the ink supply pin ink supply of printing word car 14.
On the outer wall of print cartridge 15 housings 16 chip piece 18 is installed, chip 18 has substrate, and a side of substrate is provided with a plurality of electric contacts 19, is used for being electrically connected with keyset.The opposite side of substrate is provided with the electronic module (invisible among Fig. 2) that is electrically connected with electric contact 19.
The quantity of electric contact 19 is generally 7 or 9 on the chip 18, and wherein 2 electric contacts 19 are for detecting the contact, and remaining electric contact 19 is a communication contact, and communication contact is used for being electrically connected with electronic module.The cavity of print cartridge 15 is provided with piezoelectric transducer (invisible among Fig. 2) near ink outlet port 17 places, detects the contact and is electrically connected with piezoelectric transducer, and to the piezoelectric transducer output signal of telecommunication, receive the signal of telecommunication that piezoelectric transducer returns simultaneously.
After print cartridge 15 is installed to ink-jet printer; Ink-jet printer at first applies the alternating current about 40 volts through detecting electric contact to piezoelectric transducer; Piezoelectric transducer receives and encourages the back that the vibrations and the generation signal of telecommunication take place, and the signal of telecommunication of generation returns ink-jet printer through detecting the contact.
Because the signal of telecommunication vibration frequency that piezoelectric transducer produces when ink being arranged and do not have ink is inequality, therefore the signal of telecommunication vibration frequency through judging that piezoelectric transducer returns can judge whether ink is sufficient in the print cartridge 15.
Referring to Fig. 3, electronic module is provided with controller 21 and memory 22, and memory 22 comprises nonvolatile memory 23 and volatile memory 24.Controller 21 receives the signal that ink-jet printer sends through electric contact, and judges the order of these signal representatives, operate accordingly according to command execution simultaneously, as read and write data etc.
Nonvolatile memory 23 can be EEPROM (Electrically Erasable Programmable Read-Only Memory; EEPROM) memory such as; It stores the information relevant with print cartridge; Comprise variable information and fixed information, variable information is the information that constantly changes with the printing meeting, like information such as ink surplus, printing durations; Fixed information is the information that can not change with printing, like print cartridge model, suitable ink-jet printer model, ink color etc.
Volatile memory 24 is RAM (Random Access Memory, a random access memory), and it is used for storing the data in the write non-volatile memory 23 that need of ink-jet printer transmission temporarily.
After print cartridge 15 is installed to the printing word car 14 of ink-jet printer; Ink-jet printer powers on for chip 18; Just send signal to electronic module through communication contact; And read the data that are stored in chip 18 memories 22, judge whether print cartridge 15 models are suitable, print cartridge 15 interior residual ink amount abundance etc. whether.Certainly, the signal of telecommunication that returns according to piezoelectric transducer simultaneously of ink-jet printer is judged in the print cartridge 15 whether abundance of ink surpluses.Have only judge in the suitable and print cartridge 15 of print cartridge 15 models sufficient ink is arranged after, ink-jet printer could be carried out print job.
Ink-jet printer will calculate print cartridge 15 amount of ink remaining after carrying out a printing, and the ink surplus data of upgrading are written in the memory 22.But because ink-jet printer writes the rapid speed of data to chip 18, and ink-jet printer has been after chip 18 has sent data, the power down of general's horse back.Because the writing speed of nonvolatile memory 23 is slower; Can not satisfy the job requirement of ink-jet printer, therefore, chip 18 at first with the storage that receives in volatile memory 24; After treating that ink-jet printer transmission data finish, write data into again in the nonvolatile memory 23.
Because volatile memory 24 data after power down will be lost, so also be provided with the capacitor C 1 as energy storage device in the electronic module, be used for the short time storage of electrical energy, after chip 18 power down, supply power to volatile memory 24.Therefore, ink-jet printer is when chip 18 power supplies, and capacitor C 1 charging stops after chip 18 power supplies capacitor C 1 discharge at ink-jet printer.
Yet; Because the capacitor C 1 of existing chip 18 is charged through communication contact; And the signal of telecommunication that ink-jet printer loads to communication contact is the lower direct current of voltage normally, and the charging interval is shorter, and through communication contact direct current being charged is difficult to the capacitor C that capacitance is bigger 1 and is full of; The electric weight that causes capacitor C 1 to store is limited; Can not after chip 18 power down, provide sufficient electric weight to volatile memory 24 at ink-jet printer, cause being stored in data in the volatile memory 24 fully in unloading to the nonvolatile memory 23, influence the work of chip 18.
