The utility model embodiment can be used for having in the imaging device of print cartridge position detecting function.Take ink-jet printer as example, wherein typical position probing scheme is as follows.
In order to guarantee the normal printing of ink-jet printer, prevent because print cartridge is arranged on wrong position and deviation occurs printing, usually need to detect print cartridge and whether correctly be arranged on appropriate location in ink-jet printer after print cartridge is packed printer into.Fig. 3 a and 3b are the print cartridge position probing principle schematic that the utility model embodiment is suitable for, as shown in Fig. 3 a, suppose that ink-jet printer is provided with four print cartridges, clear for distinguishing, distinguish print cartridge with color mark, be designated as black print cartridge BK, yellow print cartridge Y, Indigo print cartridge C and carmetta print cartridge M.Each print cartridge is arranged on respectively on corresponding print cartridge installation site, and its tram separately is respectively position A, position B, position C and position D as shown in Fig. 3 a.Be provided with optical receiver on ink-jet printer, its position is fixed, and comes mobile print cartridge position by mobile word car, thereby changes the relative position between optical receiver on luminescence unit on print cartridge and printer.
Position probing comprises that mainly the adjacent light over against position probing and adjacent print cartridge to current print cartridge to be detected detects two parts, need to detect each print cartridge in imaging device one by one as print cartridge to be detected.Wherein, the luminescence unit that refers to the print cartridge to be detected that printer driver is relative with optical receiver over against position probing is luminous, and detect light quantity that optical receiver receives whether greater than the process of preset value, and the adjacent light detection is to instigate above-mentioned print cartridge to be detected to maintain on the position relative with optical receiver, the luminescence unit of arbitrary print cartridge that printer driver is adjacent with above-mentioned print cartridge to be detected is luminous, and detects light quantity that optical receiver receives at this moment whether less than the process of the above-mentioned light quantity that receives during for position probing.As shown in Fig. 3 a, for print cartridge Y to be detected, can itself and optical receiver be in over against the position mobile print cartridge Y, the luminescence unit of controlling print cartridge Y to be detected is luminous, optical receiver receives light, obtains the first light quantity S1, judges that whether described the first light quantity is greater than predetermined threshold value, if this print cartridge to be detected is correct over against position probing.As shown in Fig. 3 b, keep print cartridge Y invariant position to be detected, the luminescence unit of adjacent print cartridge BK of controlling print cartridge Y to be detected is luminous, optical receiver receives light, obtains the second light quantity S2, judges that whether the first light quantity is greater than the second light quantity, if the adjacent light of this print cartridge Y to be detected detects correct.Otherwise, determine to detect mistake over against position probing or adjacent light.Only have by above-mentioned two kinds of detections and just can be considered as the correct position of this print cartridge.Wherein, in foregoing description, print cartridge to be detected is interpreted as carrying out the print cartridge over against position probing, and adjacent print cartridge is interpreted as the arbitrary print cartridge adjacent with above-mentioned print cartridge to be detected.
In order to be applicable to above-mentioned imaging device to the requirement of print cartridge position probing, do not change the setting of imaging device, site error or light quantity error that again can compatible print cartridge, the False Rate that dips and detect, the utility model embodiment provides following solution.
Fig. 4 is the flow chart of the light-emitting control method of the performed print cartridge of the control module of the utility model embodiment, this control method is applicable in following print cartridge, shown in figure 1a-1c and Fig. 2 a-2b, this print cartridge is removably mounted on imaging equipment body, and described print cartridge comprises be used to the interface unit that receives the signal that described imaging equipment body sends, store the memory cell of described print cartridge relevant information, towards being arranged on the luminous luminescence unit of optical receiver on described imaging equipment body and controlling the luminous control module of described luminescence unit, and described imaging equipment body is provided with at least two described print cartridges.Above-mentioned control method can be carried out by the control module on print cartridge, if a plurality of print cartridges are arranged in imaging device, the control module in any print cartridge can be carried out this method.The method specifically comprises the steps:
In this step, the delay timing that starts light can be to start first, or restarts after resetting for the timer that had started.
Wherein, imaging equipment body is the first period T1 for the time interval over against position probing of carrying out print cartridge to be detected, being used for carrying out the time interval that the adjacent light of print cartridge to be detected detects is the second period T2, and described delay gate limit value t is greater than the second period T2, and less than the first period T1.
The light emitting control instruction of imaging equipment body mainly is divided into two kinds, and namely light is lighted instruction and light extinguishes instruction.In the location detecting technology of imaging device, carry out all can successively sending corresponding print cartridge that light is lighted instruction and light extinguishes instruction when position probing and adjacent light detect, control the luminous regular hour of this print cartridge luminescence unit, to detect.
In practical application, the light emitting control instruction is to coordinate with mobile control to print cartridge.For example, a kind of situation is, aligns the period that position probing and adjacent light are detected independently to send paired light and light instruction and light and extinguish instruction and control, and the control print cartridge moves to over against the position in the light emitting control process.In technique scheme, above-mentioned the first period T1 be print cartridge to be detected over against position probing the time, the light that printer sends is lighted instruction and light and is extinguished time interval between instruction; The second period T2 is the adjacent light of above-mentioned print cartridge to be detected when detecting, and the light that printer sends is lighted instruction and light and extinguished time interval between instruction.Usually, the first period T1 is greater than the second period T2.
Another kind of situation, if certain print cartridge need to be as the adjacent print cartridge of other print cartridges and is luminous, again as print cartridge to be detected over against position probing and luminous, and above-mentioned twice light emitting control is continuously, can only send that one group of light is lighted instruction and light extinguishes instruction, make this print cartridge luminous all the time, namely be equivalent to over against the light emitting control instruction folding of stage position detection and adjacent light detection-phase.This period duration is at least the first period T1 and the second period T2 sum.For this situation, above-mentioned the first period T1 refers to that lighting instruction from light begins to receive till the light quantity of position probing to optical receiver, till the second period T2 refers to receive light quantity that adjacent light detects and begin to extinguish instruction to light from optical receiver.Perhaps, above-mentioned the second period T2 refers to that lighting instruction from light begins to receive till the light quantity of position probing to optical receiver, till the first period T1 refers to receive light quantity that adjacent light detects and begin to extinguish instruction to light from optical receiver.
If imaging equipment body is independent for the light emitting control instruction over against position probing and adjacent light detection that print cartridge to be detected sends, the sequencing over against position probing and adjacent light detection of each print cartridge to be detected is not limit.If as mentioned above, print cartridge to be detected luminous light emitting control instruction can merge over against position probing with as adjacent light, this scheme be applicable to that adjacent light detects position probing after or before the situation of execution.Each print cartridge is not distinguished light and is lighted instruction and light to extinguish instruction be used to carrying out over against position probing or adjacent light detects.
In this scheme, print cartridge to received light light time that instruction all postpones to set just control luminous, if do not arrive time delay, just receive light and extinguish instruction, directly control is not luminous, if arrive time delay, all do not receive light and extinguish instruction, just control luminous.Due to time delay t greater than the second period T2, be equivalent within the period of carrying out the adjacent light detection, luminescence unit is not luminous due to delay, and within the period of position probing, postpone also to have at least the fluorescent lifetime of T1-t duration after certain hour, for detection.
Optical receiver testing result in the imaging equipment body side is, in the period, still can receive light at T1, has the first light quantity, detects over against position probing accordingly correct.In period, can not receive light at T2, light quantity is zero, and is inevitable less than the first light quantity, also can judge accordingly adjacent light and detect correct.
Owing in an imaging device, a plurality of print cartridges can being installed, when different print cartridges are as print cartridge to be detected, corresponding the first period may be identical or differ from one another, and the second corresponding period also may be identical or differ from one another.If different situations, the delay gate limit value that configures of each print cartridge control module is preferably greater than the second period maximum in described imaging device, and less than the first period of minimum.If in identical situation, the delay gate limit value that configures of each print cartridge control module satisfies the regulation of above-mentioned " greater than the second period, less than the first period " and gets final product.Further, the delay gate limit value that configures of different print cartridge control modules also can be same to each other or different to each other.That is to say, can preset a plurality of delay gate limit values in memory cell, adopt at random different delay gate limit values.
The duration of the delay gate limit value t that each print cartridge control module configures is preferably set according to self making the first period T1 corresponding to print cartridge to be detected and the second period T2, preferred span is, be 300ms to 2s when the first period, and the second period, when being 1ms to 100ms, the delay gate limit value was preferably 200ms.
For after receiving light and lighting instruction, what the next one received is again that light is lighted instruction, and postpone that timing does not also stop or when resetting by previous light lighting of lighting that instruction starts, control module is restarted after can resetting for the timer that had started, light for the second time the delay timing after restarting, light for the second time delay gate limit value t2 corresponding to time-delay timing, can be identical or different with delay gate limit value t.That is to say, can preset a plurality of delay gate limit values in memory cell, adopt at random different delay gate limit values, or add up the light that receives and light the instruction number of times, call different delay gate limit values.
Extinguish for light the shorter situation of time interval T3 that instruction and next light are lighted instruction, the timing threshold value t that namely lights time-delay is during greater than the second period T2 and interval T 3 sum, can be after receiving light and extinguishing instruction, do not process lighting the time-delay timing, light after instruction zero clearing again or reset and light delay timer to carry out reclocking until receive next light.Preferably, be light when extinguishing instruction when control module recognizes described light emitting control instruction, stop the described delay timing of lighting, or described lighting postponed timing and reset, to guarantee that luminescence unit can be not luminous because of delay arrival time.
In addition, when control module recognize described light emitting control instruction be light extinguish instruction stop lighting postpone timing after, described light postpone that timing can carry out directly that zero clearing resets or after receiving next light to light instruction again zero clearing or reset also can.In like manner, when control module monitors described when lighting the clocking value that postpones timing and reaching the delay gate limit value, it stops timing, and it is luminous to control described luminescence unit, and describedly light the zero clearing that postpones timing or reset and to carry out together with stopping the timing action, also can carry out again when receiving next light and light instruction.
Hence one can see that, and the technical scheme that the utility model embodiment provides can either satisfy the specific position probing requirement of imaging device, can overcome again the False Rate defective that the foozle of print cartridge luminescence unit causes.Imaging equipment body may be sold and be in use, and this scheme need not existing a large amount of imaging equipment bodies are changed, and only needs the easily-consumed products print cartridge is improved to get final product, thereby is easy to promote realization.
Fig. 5 is the flow chart of the light-emitting control method of the performed print cartridge of the control module of the utility model embodiment.This programme can take such scheme as the basis, further be optimized the operation that light is lighted.Interface unit between each print cartridge and imaging equipment body, normally conllinear connects, be that the imaging equipment body will be issued all print cartridge control modules to the light emitting control order bloc of certain particular cartridge, whether the control object that needs the print cartridge control module to identify this light emitting control instruction is the print cartridge of self controlling.The print cartridge control module generally depends on print cartridge identifying information in the light emitting control instruction and the print cartridge identifying information in local memory cell is determined.This is also the mode of the intrinsic employing of existing a large amount of imaging equipment bodies.In aforementioned schemes, can continue to use this technical scheme, the print cartridge control module only when the light emitting control instruction that receives to local print cartridge, the operation of just lighting, delaying time or extinguishing.
This programme provides another preferred solution, specifically the print cartridge control module also can be carried out corresponding actions for the light emitting control instruction of other print cartridges, namely a print cartridge can send at least two print cartridges according to imaging equipment body, and even all the light emitting control instruction of print cartridge is carried out and lighted, delays time or extinguish operation.
Specifically, control module receives and comprises the steps: from the light emitting control instruction of described imaging equipment body and the operation of identifying
For imaging equipment body, the print cartridge identifying information be used for to be distinguished control object, i.e. print cartridge, and the light control information is used for distinguishing Control the content, and namely light is lighted instruction or light extinguishes instruction.
As previously mentioned, by technique scheme, a print cartridge can send at least two print cartridges according to imaging equipment body, and even all the light emitting control instruction of print cartridge is carried out and lighted, delays time or extinguish operation.Also namely, over against stage position detection, not only print cartridge to be detected can be luminous, in addition at least one the or all luminescence unit of print cartridges all can be luminous.Thus, the light quantity that optical receiver receives will inevitably be greater than the light quantity of a print cartridge, and namely certainty is greater than predetermined threshold value.This scheme efficiently solves the defective that causes luminescence unit luminous quantity deficiency due to foozle or electric weight deficiency, can effectively reduce False Rate.
The light-emitting control method of following print cartridge provides the preferred embodiment of an identification print cartridge take aforementioned schemes as the basis.Following table 1 is the print cartridge identifying information that is suitable for:
