In practical application, this memory element can using common nonvolatile memory, such as EPROM, EEPROM, FLASH, ferroelectric memory and phase transition storage etc., it would however also be possible to employ volatile memory adds that power supply is realized, such as SRAM+ Battery or electric capacity, DRAM+ battery or electric capacity etc..The way of realization of specific memory element is unrestricted.
In practical application, when meeting the condition of triggering state labelling change, in memory element, status indication will change, That is, the change of status indication can represent ink box chip from current state change to another one state.For example, Status indication can be represented with the mark flag of 1 bit that takes up space, and as flag=0, represents that the current state of ink box chip is Executable state, contrary, as flag=1, represent that the current state of ink box chip is not executable state.If current flag =1, and when meeting the condition of triggering state labelling change, status indication flag will change into flag=0 from flag=1, instead Then flag=1 keep constant.
In addition, the initial default value of status indication can be in executable state for indicating the state of current ink box chip, Or not executable state can be in for current instruction ink box chip, specifically, can be examined according to the light of different imaging devices Survey characteristic to be configured in advance.For example, when imaging device print cartridge is first carried out just to position detect, after carry out adjacent position detection When, the initial default value that can arrange status indication is to indicate that current ink box chip is in executable state；And work as imaging device First adjacent position detection is carried out to print cartridge, after when carrying out just position being detected, the initial default value that can arrange status indication is Indicate that current ink box chip is in not executable state.
It should be noted that in the present embodiment, the initial default value of status indication can be for indicating described ink box chip The value that state is in executable state or is in not executable state for instruction ink box chip, specifically can set according to different imagings Standby light inspection characteristic is configured, when imaging device first carries out to print cartridge just position being detected, after when carrying out adjacent position detection, The initial default value that status indication can be arranged is to represent that ink box chip is in the value of executable state；When imaging device is to print cartridge First carry out adjacent position detection, after when carrying out just position being detected, the initial default value that can arrange status indication is to represent ink Box chip is in the value of not executable state.The value of status indication, in ink box chip power-up initializing, (imaging device leaves Begin to power to ink box chip, control unit detects power supply for seasonable), or stop powering to ink box chip in imaging device When, or when receiving the light control instruction comprising specific print cartridge identification information, recover its default value.
Described luminescence unit 24 is connected with described control unit 22, for executing described light control instruction, described light The type of control instruction includes light and lights instruction or light extinguishing instruction；
In each embodiment of the present invention, luminescence unit can be arranged on ink box chip it is also possible to be not arranged in print cartridge On chip, but control unit is connected to by connection member, specifically, connection member can be wire or electrical pickoff, Or can also wirelessly realize connecting.
In addition, luminescence unit can be electroluminescent part, can be specifically light emitting diode (LED), laser two Pole pipe, fluorescent lamp and tengsten lamp etc., here is not any limitation as.Meanwhile, the light that luminescence unit is sent can be visible ray, also may be used To be black light.
It will appreciated by the skilled person that the luminescence unit in the present embodiment both may be provided at straight with optical receiver Connect relative position, may also be arranged on the position deviating, and utilize optical guidance part to guide light to optical receiver.
Described control unit 22 is connected with described interface unit 21 and described memory element 23, in described interface unit The status indication in type and described memory element when receiving described light control instruction, according to described light control instruction Described luminescence unit is controlled to execute described light control instruction；After described luminescence unit executes described light control instruction, root According to the incidence relation of described print cartridge identification information and described its own identification information, redefine status indication.
In the present embodiment, control unit is used for the light control instruction received by Processing Interface unit, and according to light The status indication of the type of control instruction and ink box chip controls to be lighted luminescence unit or extinguishes luminescence unit.That is, When described ink box chip is executable state, control unit can be lighted instruction according to described light and light luminescence unit, and When described ink box chip is not executable state, does not execute described light and light instruction, be equivalent to locking luminescence unit and be in Current state (keeps extinguishing or being remain on).It can be seen that, the status indication in the present embodiment is only used for guidance light and lights Whether instruction can execute.
Specifically, when interface unit receives light and lights instruction, control unit judges whether ink box chip is to hold Row state, if so, then control light luminescence unit, if having been changed to not executable state, control do not execute light luminous The operation of unit；And further it is contemplated that the difference of different control units response speed, control unit judges that ink box chip is During executable state, can control and directly light luminescence unit, or can also carry out after the time delay of some clock cycle (for example 300 milliseconds), then control and light luminescence unit.
Additionally, control unit is after judging whether to execute light lighting instruction, it is also possible that according to described print cartridge identification information With the incidence relation of described its own identification information, redefine status indication, that is, control the state updating ink box chip.Specifically Ground, when the light that interface unit receives lights the print cartridge identification information comprising in instruction or light extinguishing instruction and memory element When its own identification information being stored is associated, control unit rewrites the status indication in memory element, thus changing print cartridge Current state.Wherein, print cartridge identification information is associated with its own identification information and refers to match or identical, or has spy Fixed relation, for example same numerical value carries out recording with hexadecimal and octal system respectively and can be expressed as being associated.
It should be noted that the ink box chip that the present embodiment provides can be connected to imaging device by communication bus, when Multiple as the ink box chip in above-described embodiments be required to be connected with imaging device when, then these ink box chips can pass through same Bar communication bus is connected to imaging device, receives the light control instruction of this imaging device transmission.
With reference to Fig. 3, the workflow diagram of the ink box chip that Fig. 3 provides for the present embodiment, specifically can include：
Step S01：Receive the light control instruction that imaging device sends, described light control instruction includes print cartridge identification letter Breath.
Step S02：Whether the type judging light control instruction is that light lights instruction, if so, then execution step S04, Otherwise execution step S03.
Wherein, judge light control instruction, that is, judge that this instruction is that light lights instruction, or light extinguishes instruction.
Step S03：Extinguish luminescence unit.
Step S04：Judge whether the current status indication of ink box chip is executable state, if so, then execution step S05, otherwise, execution step S08；
Wherein, the judged result of the state according to ink box chip, to decide whether to light luminescence unit, if print cartridge core Piece is in not executable state, then do not light luminescence unit；If ink box chip is in executable state, light luminescence unit.
Step S05：Light luminescence unit.
Step S06：Judge whether print cartridge identification information is associated with its own identification information, if it is, execution step S07, if it is not, then execution step S08.
Step S07：Change the current status indication of ink box chip；
If current state is executable state, change into not executable state, if current state is can not Execution state, then change into executable state.
Step S08：Maintain the current state of ink box chip.
Wherein, step S02 and SO4 relate separately to judge the type of light control instruction and the status indication of ink box chip, In practical application, this two steps can also be carried out simultaneously, or first judges the state of ink box chip, judges light line traffic control afterwards The type of instruction, the execution sequence of this two steps does not affect the enforcement of the present embodiment.
In above-mentioned steps S06, can select to compare according to the characteristic of imaging device is that light lights instruction or light Extinguish instruction, instruction is lighted due to light and extinguishes instruction always successively appearance in pairs with light, its corresponding print cartridge identification simultaneously Information is also identical, then can only select one of which instruction to carry out the identification of comparison print cartridge therein in the way of using selecting one Information；When only light is lighted instruction and be there is corresponding print cartridge identification information, then light can only be selected to light instruction corresponding Print cartridge identification information is compared with ink box chip storage its own identification information.
In addition, the ink box chip that the present embodiment provides can also be on ink box chip during electricity, control unit detects print cartridge Chip is in the power-up initializing stage, just lights luminescence unit in advance, without the light when receiving imaging device Light instruction and just light luminescence unit.This makes the print cartridge of the ink box chip providing with the present embodiment be installed to imaging device In, if now imaging device is powered to ink box chip, luminescence unit just can directly light, and user then can pass through This phenomenon knows that ink box chip is normal with the electrical contact of imaging device in advance.Should be noted this advantage not only luminescence unit Transmitting visible ray just has, even if luminescence unit transmitting is black light, such as ultraviolet, when on print cartridge or imaging device When being provided with fluorescent material at the position that luminescence unit can be irradiated to, ultraviolet can force fluorescent material to light, and equally plays The effect of prompting user.
With reference to Fig. 4 and Fig. 5, Fig. 4 is the flow chart carrying out the detection of print cartridge position using existing ink box chip, and Fig. 5 is use The flow chart that the ink box chip that the present embodiment provides carries out the detection of print cartridge position.Comparing by Fig. 4 and Fig. 5, further The advantage that the ink box chip that the present embodiment provides is described.
Wherein, step S11 in Fig. 4 is corresponded to step S27 to step S17 with step S21 in Fig. 5, Fig. 4 and Tu In 5, (B) is partly the control method of print cartridge position detection, and (A) is all partly the luminescence phenomenon of luminescence unit it is assumed that imaging sets Standby print cartridge is first carried out once just position is detected, after carry out an adjacent position detection.
In Fig. 4, step S11 and S13 are steps print cartridge C being carried out respectively just to position detection and adjacent position detection, Wherein, because this four print cartridges are connected to imaging device by same communication bus, each print cartridge can receive imaging Equipment is sent to the light control instruction of any one print cartridge, carries print cartridge C identification information when imaging device all sends identical Light light instruction, due to only having the identification information of the print cartridge C that is stored with the chip of print cartridge C, therefore only print cartridge C is by point Bright, after continuing for some time, the light that print cartridge C is sent by imaging device extinguishes instruction extinguishing (not to be embodied light to extinguish in Fig. 4 The effect of instruction).
Step S12 and S15 are stages print cartridge M being carried out respectively just to position detection and adjacent position detection, this two In stage, imaging device all sends the light with print cartridge M identification information for the identical and lights instruction, in the same manner, therefore only black Box M is lit, and after continuing for some time, the light that print cartridge M is sent by imaging device extinguishes instruction and extinguishes.
Step S14 and S17 are stages print cartridge Y being carried out respectively just to position detection and adjacent position detection, this two In stage, imaging device all sends the light with print cartridge Y identification information for the identical and lights instruction, and therefore only print cartridge Y is by point Bright, after continuing for some time, the light that print cartridge Y is sent by imaging device extinguishes instruction and extinguishes.
Step S16 is stage print cartridge BK being carried out just to position detection, because BK is last print cartridge to be detected, In the case that print cartridge above is all arranged on tram, print cartridge BK is also installed into correct position certainly, therefore to ink Box BK often only carries out just position being detected.In this stage, imaging device sends the light point with print cartridge BK identification information Bright instruction, therefore only print cartridge BK are lit, and after continuing for some time, the light that print cartridge BK is sent by imaging device extinguishes instruction Extinguish.
In Fig. 5, the initial default value of the status indication of print cartridge C, M, Y and BK is all to represent that ink box chip is in executable shape State, because this four print cartridges are connected to imaging device by same communication bus, each print cartridge can receive imaging and set Preparation gives the light control instruction of any one print cartridge, and therefore in step S21, the luminescence unit of all print cartridges is all lit. Sent due to imaging device in step S11 is that light with print cartridge C identification information lights instruction again, therefore only print cartridge C Ink box chip state need update, change into not executable state from executable state.
Step S22, except print cartridge C is in not executable state, remaining, all in executable state, is therefore receiving into When lighting instruction as the light with print cartridge M identification information that equipment sends, print cartridge M, Y and BK light, and print cartridge C can not be by Light.With above-mentioned steps similarly, then the ink box chip state of print cartridge M changes into not executable state from executable state.
Step S23, the ink box chip of print cartridge C and print cartridge M all in not executable state, is therefore sent out receiving imaging device When the light of the identification information with print cartridge C sent lights instruction, the luminescence unit of print cartridge C and print cartridge M all can not be lighted, print cartridge The luminescence unit of Y and print cartridge BK is all lighted, and then the ink box chip of print cartridge C changes into executable state.
Step S24, similar with above-mentioned steps, print cartridge C, Y and BK that ink box chip is in executable state can light, Print cartridge M can not light, and then the ink box chip of print cartridge Y changes into not executable state.
Step S25, print cartridge C and BK lights, and print cartridge M and Y can not light.The ink box chip of print cartridge M changes into executable shape State.
Step S26, print cartridge C, M and BK light, and print cartridge Y can not light.The ink box chip of print cartridge BK is changed into and not can perform State.
Step S27, print cartridge C and M lights, and print cartridge Y and BK can not light.The ink box chip of print cartridge Y changes into executable shape State.
From above-mentioned contrast, just in step S21, S22 of stage position detection, S24 and S26 in Fig. 5, at least two The luminescence unit of individual print cartridge lights simultaneously, can increase the light quantity received by optical receiver when just position being detected.And in phase In step S23, S25 and S27 of adjacent stage position detection, compare corresponding step S13, S15 and S17 in Fig. 4, originally should point Bright luminescence unit is all no longer lighted, it is possible to reduce during the detection of adjacent position, the luminous quantity received by optical receiver is (if entered In the structure of print cartridge, setting stops luminescence unit to some direction scattered light to one step, then can reduce more receiving Luminous quantity).Therefore, the present invention provide ink box chip and light-emitting control method it is thus only necessary to existing ink box chip basis On, increase status indication it is possible to reduce the rate of false alarm of the imaging device leading to because of the foozle of luminescence unit or print cartridge, Even if in addition, it also avoid the position that multiple print cartridges that multiple chips are lighted or extinguishing scheme exists are installed into mistake simultaneously Put, the defect of imaging device also None- identified.
Embodiment two
Existing some imaging devices before carrying out light detection in addition it is also necessary to carry out revolving horse lantern detection to print cartridge.With in Fig. 4 As a example print cartridge arrangement mode, so-called revolving horse lantern detection, refer to make optical receiver just right with one of print cartridge, then from a side To the luminescence unit lighting print cartridge successively to another direction once, for example, from the beginning of the left side, print cartridge C, M, Y and BK are lighted successively On luminescence unit each once, judge whether optical receiver receives light always.The ink box chip of above-described embodiment possibly cannot be expired The revolving horse lantern detection of sufficient imaging device requires, and leads to imaging device to think that print cartridge is unqualified or illegal.Therefore, this enforcement The ink box chip that example provides, it can meet the light of imaging device and detect moreover it is possible to meet the revolving horse lantern of imaging device Detection.
The ink box chip that the present embodiment provides has the structure similar with the ink box chip of embodiment one offer, also includes connecing Mouth unit, control unit, memory element, wherein, control unit can also be connected with any one luminescence unit, luminous single to this Unit is controlled.The annexation of the unit of ink box chip that the present embodiment provides and existence form are provided with embodiment one Ink box chip also identical, will not be described here, only introduce different places.
Wherein, the memory element that the ink box chip that the present embodiment provides includes, at least stores its own identification information and lights Set information.Meanwhile, with reference to Fig. 6, the structure chart of the control unit of the ink box chip that Fig. 6 provides for the present embodiment, wherein, control Unit 22 includes instruction identification module 221, print cartridge identification module 222, match counter 223 and illuminated switch module 224.
In practical application, instruction identification module, for identifying the class of light control instruction that described interface unit receives Type；Instruction identification module is used for identifying that the light control instruction receiving is that light extinguishes instruction or light lights instruction；Institute State illuminated switch module, when the light control instruction for identifying in described instruction identification module lights instruction for light, obtain Current count result, obtains control corresponding with described current count result in the light setting information in described memory element Information, described control information includes forbidding lighting and enable is lighted, and controls described luminescence unit to execute described control information；Institute State print cartridge identification module, for judging described its own identification information that described print cartridge identification information and memory element stored whether Associated；Described match counter, in the case of being associated with described its own identification information in described print cartridge identification information, Current count result increases by 1.
Wherein, match counter is used for the light control instruction that statistics is associated with the print cartridge identification information in memory element Reception number of times.Illuminated switch module is used for being referred to according to light setting information, the count results of match counter and light line traffic control The type of order, controls and lights or extinguish the luminescence unit being connected to control unit.
In memory element, the light setting information of storage and current count results are used for representing the state mark of ink box chip Note, wherein, light setting information can include the corresponding relation of count results and control information, and described control information includes forbidding Light and enable is lighted, described control information can also include discharging illuminated switch module simultaneously.Can also deposit in memory element Storage command reception labelling, described command reception labelling is used for the functional statuses of illuminated switch module described in labelling, described function shape State is upstate or down state.Described command reception labelling can be used to indicate that ink box chip init state, I.e.：Command reception labelling is used for recording ink box chip and whether have received all types of light in revolving horse lantern detection process and light Instruction or light extinguish instruction, for example, when print cartridge needs to carry out revolving horse lantern detection, if this ink box chip receives revolving horse lantern In detection process, all types of light light instruction or light extinguishes instruction, then this command reception labelling records above-mentioned mistake Journey.When ink box chip initializes, the initial value of this command reception labelling represents that ink box chip is also not received by lamp inspection of galloping along on horseback In survey, all types of light light instruction or light extinguishes instruction.Print cartridge identification module can be also used in command reception mark When being designated as initial value, judge ink box chip whether have received all types of light in revolving horse lantern detection process light instruction or Person's light extinguishes instruction, accordingly, also needs to store the print cartridge identification letter of other each print cartridges in the memory element of ink box chip Breath.Have been received that in revolving horse lantern detection process, all types of light are lighted when print cartridge identification module determines ink box chip When instruction or light extinguish instruction, the initial value of command reception labelling is revised as representing all received value.And, When command reception is labeled as initial value, illuminated switch module can not light luminescence unit.
It is essentially all in pairs because light corresponding with print cartridge identification information light instruction to extinguish instruction with light successively Occur, print cartridge identification module only can be lighted instruction to light and be identified, and correspondingly match counter is also only to light Light instruction to be counted；Likewise, print cartridge identification module only can also extinguish instruction to light be identified, correspondingly Join enumerator also only light extinguishing instruction to be counted.Similarly command reception labelling can only record ink box chip is No have received all types of light in revolving horse lantern detection process and light instruction, or only whether record ink box chip receives Arrive all types of light in revolving horse lantern detection process and extinguish instruction.
As follows, citing son explanation carries out the process of print cartridge position detection using the ink box chip that this enforcement provides.Assume As equipment walking advanced to print cartridge barn lantern detection, then carry out the light detection of the step S11 to S17 as Fig. 4, meanwhile, imaging sets The toner cartridge type of standby upper installation is identical with print cartridge C, M, the Y and BK arrangement shown in Fig. 4 with print cartridge position ordering, and with table 1 light control instruction transmission order carries out revolving horse lantern detection to this four print cartridges.Finally, imaging device completes print cartridge is walked After barn lantern detection and light detection, by certain or some break down or the circulation of ink box chip that the life-span will terminate is sent out Send light to light instruction and light extinguishing instruction, inform the print cartridge that user is broken down in a flashing manner.Obviously informing use It is necessary to be shown in accurately mode during the print cartridge breaking down in family.
Sequence number Instruction type Sequence number Instruction type Sequence number Instruction type
1 Light print cartridge C 4 Extinguish print cartridge M 7 Light print cartridge BK
2 Extinguish print cartridge C 5 Light print cartridge Y 8 Extinguish print cartridge BK
3 Light print cartridge M 6 Extinguish print cartridge Y
Table 1
Assume that match counter is incremented by counting, and count from zero, the ink receiving when the judgement of print cartridge identification module When box identification information its own identification information stored with memory element is associated, match counter increases counting once, only to light Line is lighted instruction and is counted.Meanwhile, the light according to this imaging device detects characteristic, can be in advance in the storage of print cartridge C, M and Y In unit, setting light setting information is：
When match counter is counted as 0, control information is to forbid that illuminated switch module lights luminescence unit；
When match counter is counted as 1, control information is to enable illuminated switch module to light luminescence unit；
When match counter is counted as 2, control information is to forbid that illuminated switch module lights luminescence unit；
Match counter be counted as 3 and more than 3 several when, control information be release illuminated switch module function, print cartridge Identification module judges that the light receiving lights its own identification information that the print cartridge identification information of instruction and memory element are stored When associated, illuminated switch module lights luminescence unit；
The initial value of command reception labelling represents that ink box chip is also not received by all types in revolving horse lantern detection process Light light instruction.
Due to only carrying out to print cartridge BK just position being detected in step S16 in the diagram, do not carry out adjacent position detection, because This compares the light setting information of other ink box chips, the light setting information of print cartridge BK match counter be counted as 2 and 2 with On several when, control information be discharge illuminated switch module function.
In the sequence number 1 of above-mentioned table 1 is to the sequence number 8 instruction period, optical receiver is just right with print cartridge C, to print cartridge C, M, Y and BK Carry out revolving horse lantern detection.Light and extinguish the luminescence unit on this four print cartridges successively.
Sequence number 1 to 2 instructs the period, and what each ink box chip determined sequence number 1 by instruction identification module is that light is lighted During instruction, it is all zero because now the match counter of all ink box chips counts, according to the light setting information of memory element, This period does not have luminescence unit to be lighted by illuminated switch module, and then print cartridge identification module determines the light of sequence number 1 and lights Instruction contains print cartridge C identification information, and the therefore only match counter increase of print cartridge C once counts, and count value is changed into 1.Refer to Make that identification module determines sequence number 2 be that light extinguishes instruction when, illuminated switch module is not affected by light setting information, will Luminescence unit extinguishes.Print cartridge identification module and match counter do not extinguish instruction to the light of sequence number 2 and process.
Sequence number 3 to 4 instructs the period, and what each ink box chip determined sequence number 3 by instruction identification module is that light is lighted During instruction, it is all zero that the match counter of print cartridge M, Y and BK counts, according to the light setting information of memory element, this period The luminescence unit of print cartridge M, Y and BK all can not be lighted by illuminated switch module；The match counter of print cartridge C is counted as 1, according to depositing Control information in the light setting information of storage unit, the luminous development module of print cartridge C is enabled, but due to command reception mark Note is still initial value, and the luminescence unit of print cartridge C still can not be lit.Then print cartridge identification module determines the light point of sequence number 3 Bright instruction contains print cartridge M identification information, and the therefore only match counter increase of print cartridge M once counts, and count value is changed into 1. When what instruction identification module determined sequence number 4 is that light extinguishes instruction, illuminated switch module is not affected by light setting information, Luminescence unit is extinguished.Print cartridge identification module and match counter do not extinguish instruction to the light of sequence number 4 and process.
Sequence number 5 to 6 instructs the period, in the same manner, does not still have the luminescence unit of print cartridge to be lit.Print cartridge identification module judges Light to sequence number 5 is lighted instruction and is contained print cartridge Y identification information, and the match counter increase of print cartridge Y once counts, count value It is changed into 1.
Sequence number 7 to 8 instructs the period, in the same manner, does not still have the luminescence unit of print cartridge to be lit.Print cartridge identification module judges Light to sequence number 7 is lighted instruction and is contained print cartridge BK identification information, and the match counter increase of print cartridge BK once counts, and counts Value is changed into 1.To now, the match counter of each ink box chip has all had been counted by 1, and the print cartridge of each chip identifies Module all it is determined that have received all types of light in revolving horse lantern detection process to light instruction, therefore each ink box chip Command reception labelling all by initial value be revised as represent revolving horse lantern detection process in all types light light instruction connect The value received.When what instruction identification module determined sequence number 8 is that light extinguishes instruction, illuminated switch module is not subject to light setting information Impact, luminescence unit is extinguished.Print cartridge identification module and match counter do not extinguish at instruction to the light of sequence number 8 Reason.
Therefore, in whole revolving horse lantern detection process, the luminescence unit of each ink box chip is not all lit.Complete away After barn lantern detection, imaging device starts to carry out light detection to print cartridge, and in this light detection process, imaging device sends to ink box chip Light control instruction with order as the step S11 to S17 in Fig. 4.
When the light receiving the identification information that step S11 comprises print cartridge C lights instruction, due to each ink box chip Match counter has all had been counted by 1, and initial value is all revised as expression by the command reception labelling of each ink box chip gallops along on horseback During lamp inspection is surveyed, all types light lights the received value of instruction, and control unit is connected by therefore all ink box chips Luminescence unit is lighted.Again because this light lights the identification information that instruction comprises print cartridge C, the therefore match counter of print cartridge C increases Plus once count, count value is changed into 2.When receiving light extinguishing instruction, luminescence unit is all extinguished by all print cartridges.
When the light receiving the identification information that step S12 comprises print cartridge M lights instruction, the match counter of print cartridge C Have been counted by 2, the therefore luminescence unit of print cartridge C can not be lit, and remaining is all lighted.Again because this light lights instruction Comprise the identification information of print cartridge M, the therefore match counter increase of print cartridge M once counts, and count value is changed into 2.Receive light When extinguishing instruction, luminescence unit is all extinguished by all print cartridges.
When the light receiving the identification information that step S13 comprises print cartridge C lights instruction, the coupling of print cartridge C and M counts Device has all had been counted by 2, and the therefore luminescence unit of print cartridge C and M can not be lit, and remaining is all lighted.Again due to this light Light the identification information that instruction comprises print cartridge C, the therefore match counter increase of print cartridge C once counts, and count value is changed into 3.Connect When receiving light extinguishing instruction, luminescence unit is all extinguished by all print cartridges.
When the light comprising print cartridge Y identification information receiving step S14 lights instruction, the coupling of print cartridge C and M counts Device has count down to 3 and 2 respectively, according to the setting of aforementioned light setting information, discharges luminous opening when match counter count down to 3 Close module, the therefore luminescence unit of print cartridge C and M can not be lit, and remaining is all lighted.Light instruction due to this light to comprise again The match counter increase of the identification information of print cartridge Y, therefore print cartridge Y once counts, and count value is changed into 2.Receive light to extinguish During instruction, luminescence unit is all extinguished by all print cartridges.
When the light comprising print cartridge M identification information receiving step S15 lights instruction, the coupling meter of print cartridge C, M and Y Number device has count down to 3,2 and 2 respectively, and according to the setting of aforementioned light setting information, the release when match counter count down to 3 is sent out Optical switch module, the therefore luminescence unit of print cartridge C, M and Y can not be lit, and the luminescence unit of only print cartridge BK is lit.And by Light the identification information that instruction comprises print cartridge M in this light, the therefore match counter increase of print cartridge M once counts, count value It is changed into 3.When receiving light extinguishing instruction, luminescence unit is all extinguished by all print cartridges.
When the light comprising print cartridge BK identification information receiving step S16 lights instruction, the coupling of print cartridge C, M and Y Enumerator has count down to 3,3 and 2 respectively, according to the setting of aforementioned light setting information, discharges when match counter count down to 3 The function of illuminated switch module, the therefore luminescence unit of print cartridge C, M and Y can not be lit, only the luminescence unit quilt of print cartridge BK Light.Again because this light lights the identification information that instruction comprises print cartridge BK, therefore the match counter increase of print cartridge BK once Count, count value is changed into 2.When receiving light extinguishing instruction, luminescence unit is all extinguished by all print cartridges.
When the light comprising print cartridge Y identification information receiving step S17 lights instruction, print cartridge C, M, Y and BK Join enumerator and count down to 3,3,2 and 2 respectively, according to the setting of aforementioned light setting information, count in the coupling of print cartridge C and M Device count down to the function of discharging illuminated switch module when 3, discharges illuminated switch mould when the match counter of print cartridge BK count down to 2 The function of block, the therefore luminescence unit of print cartridge C, M, Y and BK all can not be lit.Lighting instruction due to this light comprises print cartridge again The match counter increase of the identification information of Y, therefore print cartridge Y once counts, and count value is changed into 3.Receive light and extinguish instruction When, luminescence unit is all extinguished by all print cartridges.It can be seen that, the luminescence unit luminescence phenomenon of the present embodiment is similar to left side in Fig. 9 to be shown Luminescence phenomenon.
So far, the match counter of all ink box chips has all count down to the number of each self-defining release illuminated switch print cartridge Value, imaging device can carry out accurately light emitting control to certain specific ink box chip.Therefore, in imaging device, print cartridge is entered After walking barn lantern detection and light detection, if it find that the installation of certain print cartridge is wrong or certain ink box chip will terminate the life-span (usually finding that ink soon runs out of after testing) is it is possible to be referred to by the light line traffic control sending with this print cartridge identification information Order, controls the light-emitting unit on this print cartridge to light, to reach the effect of prompting user.It can be seen that the print cartridge of employing the present embodiment Chip and its control method, do not interfere with the function of this accurate prompting.
It is pointed out that some imaging devices are sent to the light of ink box chip in revolving horse lantern detection and light detection process Line lights instruction and the light sending after these two phases, and to light instruction different, for example same comprise print cartridge C identification and believe The light of breath lights instruction, and when this two stages, instruction can be a kind of form, and after this two stages, instruction is but Another form.Because ink box chip is when the light receiving both different-formats lights instruction, to luminescence unit Control different, that is, when this two stages, if ink box chip receives light and lights instruction, luminescence unit will be by constant electricity Pressure drives, and keeps length bright it is possible to this is called that long bright light rays light instruction；And after these two phases, if print cartridge core Piece receives light when lighting instruction, and luminescence unit will be by pulsewidth modulation (Pulse-WidthModulation, PWM) voltage Drive, glisteningly bright it is possible to this is called that scintillation light lights instruction.Because long bright light rays light instruction and glittering light Lighting instruction has obvious difference, therefore, can light instruction configuration light setting letter just for long bright light rays in the present embodiment , it is not required that lighting function to the release of illuminated switch module, ink box chip lights instruction to glittering light can be using release for breath The mode lighting function is processed, and that is, print cartridge identification module judges that the glittering light receiving lights the print cartridge identification letter of instruction When breath is associated with its own identification information that memory element is stored, illuminated switch module lights luminescence unit.
Match counter in the present embodiment and command reception labelling, in ink box chip power-up initializing, or are becoming As equipment stop to ink box chip power when, be zeroed out or recover default value.In addition, in the present embodiment, in ink box chip During upper electricity, control unit detects ink box chip and is in the power-up initializing stage, just lights luminescence unit in advance, without Light when receiving imaging device lights instruction.Such advantage is：Print cartridge when the ink box chip with the present embodiment When being installed in imaging device, if now imaging device is powered to ink box chip, luminescence unit just can light, and uses By this phenomenon, family can know that ink box chip is normal with the electrical contact of imaging device in advance.
Embodiment three
The ink box chip that the present embodiment provides has the structure similar with embodiment one, also includes interface unit, controls single Unit, memory element and luminescence unit.The annexation of the unit of the ink box chip of the present embodiment and existence form and enforcement The ink box chip of example one is identical, will not be described here, and only introduces different places.
The memory element of the ink box chip that the present embodiment provides, at least stores its own identification information.It should be noted that this The control unit of the ink box chip that embodiment provides can only carry out light and extinguish instruction, when meeting default extinguishing condition, will Luminescence unit extinguishes.
Specifically, on ink box chip during electricity, control unit detects ink box chip and is in the power-up initializing stage, just carries Front luminescence unit is lighted, light instruction without the light when receiving imaging device.Such advantage is：When carrying When the print cartridge of the ink box chip that the present embodiment provides is installed in imaging device, if now imaging device is to ink box chip Power supply, then luminescence unit just can light, and user can know the electricity of ink box chip and imaging device in advance by this phenomenon Contact is normal.
Hereafter, control unit receives the light of imaging device transmission when lighting instruction, because luminescence unit is already on, No longer execute this instruction.After a period of time, imaging device sends light and extinguishes instruction, and control unit is received by interface unit After this light extinguishes instruction, judge whether to meet default extinguishing condition, that is, judge the print cartridge identification information that receives whether with storage In unit, its own identification information of storage is associated, if association, controls and extinguishes luminescence unit.
With reference to Fig. 7, the workflow diagram of the ink box chip that Fig. 7 provides for the present embodiment, specifically can include：
Step S31, starts to power to ink box chip in imaging device, during ink box chip power-up initializing, will be connected to control The luminescence unit of unit processed is lighted.
Step S32, control unit receives the light control instruction that imaging device sends, described smooth line traffic control by interface unit System instruction includes print cartridge identification information.
Step S33, control unit judges whether the type of light control instruction is that light extinguishes instruction, if it is, going to Step S35；If not, going to step S34；
Step S34, does not execute light control instruction, maintains the present situation of luminescence unit；
If current state luminescence unit is lighted, it is remain on；If current state luminescence unit is to extinguish, Then maintain and extinguish.
Step S35, control unit judges its own identification information phase whether with storage in memory element for the print cartridge identification information Association, if it is, go to step S36.If not, going to step S34；
Step S36, control unit controls extinguishes luminescence unit.
Obviously, the work process of above-mentioned ink box chip requires the light control instruction that imaging device sends must include print cartridge Identification information, but the light control instruction that not all types of imaging device sends all necessarily includes print cartridge identification information, Therefore, the present embodiment can also make following change to ink box chip：
The memory element of ink box chip except storing its own identification information, also at least storage state labelling, use by status indication It is in executable state or non-executable state in the state indicating described ink box chip, its definition and default value set-up mode are Through being described in embodiment one, here is omitted.Different from embodiment one, the status indication of the present embodiment, be for Guidance light extinguishes whether instruction can execute.
Additionally, control unit is after light lights instruction judging light control instruction, can also be according to default triggering bar Part, controls the state updating ink box chip.Specifically, light, when interface unit receives light, the print cartridge identification comprising in instruction When information is associated with its own identification information that memory element is stored, control unit rewrites the status indication in memory element, Thus changing the current state of print cartridge.
Reference Fig. 8, the workflow diagram of the ink box chip that Fig. 8 provides for the present embodiment, wherein, the storage of this ink box chip Unit storage state labelling, this flow chart specifically can include：
Step S41, starts to power to ink box chip in imaging device, during ink box chip power-up initializing, will be connected to control The luminescence unit of unit processed is lighted.
Step S42, control unit receives the light control instruction that imaging device sends, described smooth line traffic control by interface unit System instruction includes print cartridge identification information.
Step S43, control unit judges whether the type of light control instruction is that light extinguishes instruction, if it is, going to Step S44；If not, going to step S45.
Step S44, judges whether the current status indication of ink box chip is in executable state, if it is, going to step Rapid S46；If not, going to step S47.
Judge whether to meet default extinguishing condition, that is, judge the state of ink box chip, to decide whether that extinguishing is luminous Unit.
Step S45, control unit judges that the light that interface module receives is lighted the print cartridge identification information comprising in instruction and is The no its own identification information with storage in memory element is associated, if not, going to step S47；If it is, going to step S48.
Step S46, control unit controls extinguishes luminescence unit.
Step S47, does not execute light control instruction, maintains the present situation of luminescence unit.
Step S48, changes the current state of ink box chip.
If current state is executable state, change into not executable state, if current state is can not Execution state, then change into executable state.
It can be seen that, due to increasing status indication in the memory unit, using light light print cartridge identification information in instruction Lai Precisely extinguish the luminescence unit of the ink box chip being suitable for, even if the light receiving extinguishes in instruction does not include print cartridge identification information, This avoid and other luminescence units that can't extinguish are extinguished.
Below, taking the light control instruction that imaging device sends as a example, this light control instruction comprises print cartridge identification simultaneously Information, with reference to Fig. 9, Fig. 9 is the flow chart carrying out the detection of print cartridge position using the ink box chip that the present embodiment provides, by Fig. 9 Shown (A) partly and (B) part, illustrate the present embodiment advantage it is assumed that the default value of the status indication of memory element represents black Box chip is in not executable state：
Step S51, starts to power to ink box chip in imaging device, during ink box chip power-up initializing, will be connected to control The luminescence unit of unit processed is lighted.
Step S52, successively receives light corresponding with print cartridge C identification information and lights instruction and light extinguishing instruction.
The light comprising print cartridge C identification information that ink box chip first receives imaging device transmission lights instruction, Suo Youmo The luminescence unit of box all maintains original luminance, memory element is stored to the ink box chip of status indication, print cartridge C's Ink box chip can change status indication, will ink box chip never executable state changes into executable state.A period of time mistake Afterwards, ink box chip receives the light extinguishing instruction comprising print cartridge C identification information of imaging device transmission again.Due to print cartridge C's The current state of ink box chip is executable state, meets default extinguishing condition, therefore can execute this light and extinguish instruction, will Luminescence unit on print cartridge C extinguishes (not embodying the effect that light extinguishes instruction in Fig. 9)；Believe at least storing itself identification The ink box chip of breath is because its own identification information that this print cartridge identification information is stored with the memory element of print cartridge C is associated, full The default extinguishing condition of foot, so the luminescence unit of print cartridge C is off.Although other ink box chips also receive light extinguishes instruction, But all it is unsatisfactory for the default extinguishing condition that can extinguish, therefore all continue to keep luminous.
Step S53, successively receives light corresponding with print cartridge M identification information and lights instruction and light extinguishing instruction.
Instruction is lighted for light, the luminescence unit of print cartridge C keeps extinguishing, and the luminescence unit of print cartridge M, Y and BK all keeps Luminous.For the ink box chip of storage state labelling, the ink box chip of print cartridge M can change current status indication, will print cartridge Never executable state changes into executable state to chip.Instruction is extinguished for light later, the ink box chip of print cartridge M meets Default extinguishing condition, the luminescence unit of print cartridge M is off, and the luminescence unit of print cartridge Y and BK continues to keep luminous.
Step S54, successively receives light corresponding with print cartridge C identification information and lights instruction and light extinguishing instruction.
Instruction is lighted for light, the luminescence unit of print cartridge C and M all keeps extinguishing, and the luminescence unit of print cartridge Y and BK is all protected Hold luminous.Now the ink box chip of print cartridge C is which kind of state is nonsensical, now can also change status indication and then change Become the state of ink box chip it is also possible to setting status indication can only be modified once and (therefore specifically can not change status indication again ).Instruction is extinguished for light later, print cartridge Y and BK is unsatisfactory for default extinguishing condition, its luminescence unit continues to keep sending out Light.
Step S55, successively receives light corresponding with print cartridge Y identification information and lights instruction and light extinguishing instruction.
Instruction is lighted for light, the luminescence unit of print cartridge C and M all keeps extinguishing, and the luminescence unit of print cartridge Y and BK is all protected Hold luminous.For the ink box chip of storage state labelling, the ink box chip of print cartridge Y can change current status indication, by print cartridge Never executable state changes into executable state to chip.Instruction is extinguished for light later, the ink box chip of print cartridge Y meets Default extinguishing condition, the luminescence unit of print cartridge Y is off, and the luminescence unit of print cartridge BK continues to keep luminous.
Step S56, successively receives light corresponding with print cartridge M identification information and lights instruction and light extinguishing instruction.
Instruction is lighted for light, the luminescence unit of print cartridge C, M and Y all keeps extinguishing, and the luminescence unit of print cartridge BK keeps Luminous.Now the ink box chip of print cartridge M is which kind of state is nonsensical, now can also change current status indication and enter And change the state of ink box chip it is also possible to setting status indication can only be modified once and (therefore specifically can not change state again Marked).Instruction is extinguished for light later, print cartridge BK is unsatisfactory for default extinguishing condition, its luminescence unit continues to keep sending out Light.
Step S57, successively receives light corresponding with print cartridge BK identification information and lights instruction and light extinguishing instruction.
Instruction is lighted for light, the luminescence unit of print cartridge C, M and Y all keeps extinguishing, and the luminescence unit of print cartridge BK keeps Luminous.For the ink box chip of storage state labelling, the ink box chip of print cartridge BK can change current status indication by print cartridge core Never executable state changes into executable state to piece.Instruction is extinguished for light later, the ink box chip of print cartridge BK meets Default extinguishing condition, the luminescence unit of print cartridge BK is off, and to herein, the luminescence unit of all print cartridges is all off.
Step S58, successively receives light corresponding with print cartridge Y identification information and lights instruction and light extinguishing instruction.
Instruction is lighted for light, the luminescence unit of print cartridge C, M, Y and BK all keeps extinguishing.The now print cartridge core of print cartridge Y Piece is which kind of state is nonsensical, now can also change current status indication and then change the state of ink box chip, Status indication can also be set and can only be modified once (therefore specifically can not change status indication again).For light later Extinguish instruction, the luminescence unit of all print cartridges all keeps extinguishing.
It can be seen that, the ink box chip of two schemes of the present embodiment and its light-emitting control method, do not execute light and light instruction, and According to pre-conditioned whether meet be selectively carrying out light extinguish instruction, all serve the technique effect of embodiment one：Reduce Because of the rate of false alarm of the imaging device that the foozle of luminescence unit or print cartridge leads to, it also avoid multiple chips light simultaneously or Even if person extinguishes the position that multiple print cartridges that scheme exists are installed into mistake, the defect of imaging device also None- identified.
Example IV
The ink box chip that the present embodiment provides has the structure similar with embodiment one, also includes interface unit, controls single Unit, memory element and luminescence unit.The present embodiment provide the annexation of the unit of ink box chip and existence form with The ink box chip of embodiment one is identical, will not be described here, and only introduces different places.
The memory element of the present embodiment, at least stores its own identification information.Meanwhile, control unit execution light lights instruction Extinguish instruction with light, when ink box chip receives light and extinguishes instruction and meet default extinguishing condition, luminescence unit is put out Go out.
Control unit receives the light of imaging device transmission when lighting instruction, without consider to send with this instruction Print cartridge identification information, that is, without considering which control object is, can directly control the luminous list being connected to control unit Unit is luminous, or controls luminescence unit to be lighted after time delay certain time.After a period of time, imaging device sends light and extinguishes Instruction, control unit, after interface unit receives the extinguishing instruction of this light, judges whether to meet default extinguishing condition, that is, sentences The disconnected print cartridge identification information sending together with the light control instruction whether its own identification information phase with storage in memory element Association, if association, controls and extinguishes luminescence unit.
With reference to Figure 10, the workflow diagram of the ink box chip that Figure 10 provides for the present embodiment, specifically can include：
Step S61, control unit receives, by interface unit, light control instruction and the print cartridge identification that imaging device is sent Information.
Step S62, judges whether light control instruction is that light lights instruction, if it is not, then jumping to step S63, if so, Jump to step S66.
Step S63, control unit judges itself identification whether with storage in memory element for the print cartridge identification information receiving Information is associated, if not, jumping to step S64；If it is, going to step S65.
Step S64, does not execute light control instruction, maintains the present situation of luminescence unit；
If current state luminescence unit is lighted, it is remain on；If current state luminescence unit is to extinguish, Then maintain and extinguish.
Step S65, control unit controls extinguishes luminescence unit.
Step S66, control unit starts timing, and judges whether timing receives new light control instruction before terminating, If it is, jumping to step S62；Otherwise jump to step S67.
Hypothesis timer expiration value is T, arrives timing arrival T during this starting timing, control unit judges whether to connect Have received new light control instruction, if having received new light control instruction, jumping to step S62；On the contrary, if In this process, it is not received by new light control instruction, just jump to step S67.

Step S71, control unit receives the light control instruction that imaging device is sent, described smooth line traffic control by interface unit System instruction includes print cartridge identification information.
Step S72, judges whether light control instruction is that light lights instruction, if so, then jumps to step S73 and S75, Otherwise, jump to step S77.
Step S73, control unit starts timing, and judges whether timing receives new light control instruction before terminating, If it is, jumping to step S72；Otherwise jump to step S74.
Control unit determines light control instruction when being that light lights instruction, and control unit starts timing it is assumed that timing Stop value is T, arrives timing arrival T during this starting timing, control unit judges whether to have received new light line traffic control System instruction, if having received new light control instruction, jumps to step S72；On the contrary, if in this process, do not have Have and receive new light control instruction, just jump to step S74.
Step 74, at the end of timing, lights luminescence unit.
When timing reaches T, namely at the end of timing, control unit controls lights luminescence unit.This is equivalent to time delay Control again after timing T and light luminescence unit.
Step S75, when it is that light lights instruction that control unit determines light control instruction, control unit judges to receive Print cartridge identification information whether be associated with its own identification information of storage in memory element, if not, jumping to step S76； If it is, jumping to step S80.
Step S76, maintains the current state of ink box chip；
If current state is executable state, maintain executable state；If current state is not can perform State, then maintain not executable state.
Step S77, control unit determine light control instruction be light extinguish instruction when, judge that ink box chip is current Whether status indication is in executable state, if it is, jumping to step S78, otherwise, jumps to step S79；
Step S78, control unit controls extinguishes luminescence unit, and jumps to step S80.
Step S79, does not execute light and extinguishes instruction, maintain the present situation of luminescence unit；
If current state luminescence unit is lighted, it is remain on；If current state luminescence unit is to extinguish, Then maintain and extinguish.
Step S80, changes ink box chip status indication；
If current state is executable state, change into not executable state；If current state is can not Execution state, then change into executable state.
It can be seen that, due to increasing status indication in the memory unit, using light light print cartridge identification information in instruction Lai Precisely extinguish the luminescence unit of the ink box chip being suitable for, even if light extinguishes in instruction does not include print cartridge identification information, so Avoid to extinguish other luminescence units that can't extinguish.
