Description
Technical field
The present invention relates to the printing field, especially relate to a kind of chip that is arranged on print cartridge on ink-jet printer and this print cartridge, the ink-jet printer of this print cartridge is installed.
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, to form word or the pattern that needs printing 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 casing 11, and be provided with a slide bar 20, print word car 14 and move back and forth along slide bar 20 under the drive of motor (invisible in Fig. 1).Print in word car 14 and be provided with keyset (invisible in Fig. 1), keyset communicates by winding displacement 13 and movement 12.
Referring to Fig. 2, print word car 14 and have cavity 21, a plurality of print cartridges 15 removably are installed in cavity 21, accommodate the ink of different colours in different print cartridges 15.The hull outside of printing word car 14 is provided with a plurality of installing plates 22, offers installing hole 23 on each installing plate 22, and slide bar 20 passes installing hole 23.
Referring to Fig. 3, 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 cavity flows out by ink outlet port 17, and to print word car 14 for the tattooing needle ink supply.
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 to keyset.The opposite side of substrate is provided with the electronic module (invisible in Fig. 3) that is electrically connected to electric contact 19.
Referring to Fig. 4, electronic module is provided with controller 31 and memory 32, and memory 32 comprises nonvolatile memory 33 and volatile memory 34.Controller 31 receives by electric contact the signal that ink-jet printer sends, and judges the order of these signal representatives, and the while operates accordingly according to command execution, as read and write data etc.
Nonvolatile memory 33 can be EEPROM(Electrically Erasable Programmable Read-Only Memory, EEPROM) memory such as, it stores the information relevant to print cartridge, comprise variable information and fixed information, variable information is the information that constantly changes with the printing meeting, as information such as ink surplus, printing durations, fixed information is the information that can not change with printing, as print cartridge model, applicable ink-jet printer model, ink color etc.
Volatile memory 34 is RAM(Random Access Memory, random access storage device), it is used for that interim storage ink-jet printer sends needs data in write non-volatile memory 33.
After print cartridge 15 is installed to the printing word car 14 of ink-jet printer, ink-jet printer powers on to chip 18, namely by electric contact to the electronic module transmitted signal, and read the data that are stored in chip 18 memories 32, judge whether print cartridge 15 models are suitable, the interior residual ink amount of print cartridge 15 abundance etc. whether.Only have in the suitable and print cartridge 15 of judgement print cartridge 15 models, sufficient ink is arranged after, ink-jet printer could be carried out print job.In ink-jet printer when work, prints word car 14 and move back and forth along slide bar 20, so print cartridge 15 is also reciprocating along slide bar 20, i.e. during ink-jet printer work, print cartridge 15 is relative motions with casing 11.
Ink-jet printer will calculate the remaining quantity of ink of print cartridge 15 after carrying out a printing, and the ink surplus data of upgrading are written in memory 32.But, due to the speed of ink-jet printer to chip 18 data writings, and after ink-jet printer sends data to chip 18, power down at once.Because the writing speed of non-volatile memories 33 is slower, can not satisfy the job requirement of ink-jet printer, therefore, at first chip 18 is stored in the data that receive in volatile memory 34, after ink-jet printer transmission data are complete, then write data in nonvolatile memory 33.
Because volatile memory 34 data after power down will be lost, so also be provided with the capacitor C 1 as energy storage device in electronic module, be used for the short time storage of electrical energy, power to volatile memory 34 after chip 18 power down.Therefore, when ink-jet printer is powered to chip 18, to capacitor C 1 charging, stop after chip 18 power supplies capacitor C 1 discharge by electric contact at ink-jet printer.
Yet, because the capacitor C 1 of existing chip 18 is charged by electric contact, and the signal of telecommunication that ink-jet printer loads to electric contact is the lower direct current of voltage normally, charging interval is shorter, by electric contact, direct current is charged and be difficult to the capacitor C that capacitance is larger 1 and be full of, the electric weight that causes capacitor C 1 to store is limited, can not provide the electric weight of abundance to volatile memory 34 after chip 18 power down at ink-jet printer, cause being stored in volatile memory 34 data fully unloading to nonvolatile memory 33, affect the work of chip 18.
