Detailed description of the invention
For fully disclosing and embodying the advantage of various aspects of the present invention, below in conjunction with accompanying drawing, each exemplary embodiment of the present invention is described.
Embodiment one
The invention provides the detachable disjunctor chip for imaging cartridge of a kind of appendage, multiple such disjunctor chip is connected to printing imaging device by serial common bus, as shown in Figure 2, this disjunctor chip includes appendage and major part, appendage is connected, possibly in an attachable fashion, to major part, in Fig. 2 with disjunctor chip 100 and disjunctor chip 200 for be illustrated disjunctor chip composition and with the connected mode printing imaging device.Wherein, the address of devices of disjunctor chip 100 is for " 010 " and be stored in major part, its appendage can distribution devices address also can not distribution devices address.Major part and appendage are all provided with interface circuit separately, can be connected on serial common bus.Similarly, disjunctor chip 200 also comprises major part and appendage, and its address of devices " 110 " is also stored in major part.Disjunctor chip of the present invention, possesses the function of the OEM box chip of original-pack manufacturers produce, when attaching it to imaging cartridge, can coordinate and print imaging device work as OEM box chip.
Fig. 3 shows the structure composition of the appendage of disjunctor chip, and it comprises:
Interface unit 10, is connected to printing imaging device by serial common bus, and it is for receiving the instruction printing imaging device and send;
Memory cell 12, which stores the information of the different imaging cartridges being common to same printing imaging device, and these information both may be used for certain specific imaging cartridge, also may be used for other the imaging cartridge being applicable to same printing imaging device.This general information can be fix information, also can be variable information.This memory cell can adopt common nonvolatile memory, such as EPROM, EEPROM, FLASH memory, ferroelectric memory, phase transition storage etc., also volatile memory can be adopted to add the scheme of power supply, such as SRAM+ battery or electric capacity, DRAM+ battery or electric capacity;
Response recognition unit 14, it for identifying, whether serial common bus exists response;
Priority level dispensing unit 13, it has preset priority level; With
Control unit 11, when receiving the instruction printing imaging device transmission, in the moment corresponding according to the priority level preset, control response recognition unit 14 identifies the response on serial common bus, and the instruction of response printing imaging device.
Respond recognition unit 14 recognize serial common bus do not exist response time, the general information that memory cell 12 stores is sent to printing imaging device by interface unit 10 by control unit 11.
The appendage of different disjunctor chips, the default priority level of its priority level dispensing unit is different, priority level is higher, then identify and whether serial common bus exist other box chips that the moment of moment of response of (general designation being above-mentioned disjunctor chip, compatibility box chip and the OEM box chip of original-pack manufacturers produce) and the instruction of response printing imaging device is relative forward; On the contrary, priority level is lower, then identify and whether serial common bus exist other box chips that the moment of moment of response of (general designation being above-mentioned disjunctor chip, compatibility box chip and the OEM box chip of original-pack manufacturers produce) and the instruction of response printing imaging device is relative rearward.This moment is that the trailing edge sending last clock information of instruction with printing imaging device compares.Therefore, also can be understood as the priority level dispensing unit of default priority level, this priority level specifically identifies that moment of the response whether serial common bus existing other box chips and response print moment of instruction of imaging device, and the identification moment that different priority levels is corresponding is different with response moment difference.Such as, having preset the priority level dispensing unit that priority level is higher, its identification moment stored trailing edge of last clock information near print imaging device send instruction relative to the response moment, is also above-mentioned relatively forward; Preset the priority level dispensing unit that priority level is lower, its identification moment stored trailing edge of last clock information away from print imaging device send instruction relative to the response moment, also namely above-mentioned relative rearward.
The information stored due to the memory cell of appendage is a part for all information of whole disjunctor chip, and therefore, the addressing of the addressing of the memory cell of appendage and the memory of major part is continuous print.For the addressing mapping graph of the disjunctor chip 100 in Fig. 4, the fix information of three bytes of appendage, be addressed to first three reference address, be respectively " 01 ", " 02 " and " 03 ", the fix information of these three bytes is the general informations being common to other imaging cartridges, the i.e. appendage of disjunctor chip 200, also stores the general information of these three bytes.And the addressing of major part is from reference address " 04 ", major part stores fix information and variable information.Therefore, when appendage or major part receive the instruction printing imaging device, according to the reference address in instruction, can judge self whether to store information corresponding to this reference address, thus feed back to printing imaging device.Below, two imaging cartridges (namely only disjunctor chip 100 and disjunctor chip 200 are connected to serial common bus as shown in Figure 2) have only been installed and composition graphs 2 to Fig. 6 illustrates the function and efficacy of above-mentioned appendage unit module to print in imaging device.
When the instruction printing imaging device transmission contains address of devices " 010 " and reference address " 04 ", the major part of disjunctor chip 100 is by judging these address of devices and reference address, this instruction can be confirmed and be calling self and the fix information being addressed to " 04 " for access, the falling edge of last clock signal then after instruction, feeds back to printing imaging device by the fix information of reference address " 04 ".Because the appendage of disjunctor chip 100 does not comprise the fix information being addressed to " 04 ", thus this appendage recognizes this instruction and non-call self, ignores this instruction and enters holding state.And the address of devices of disjunctor chip 200 is " 110 ", therefore the major part of disjunctor chip and appendage can confirm this instruction and non-call self by address of devices or reference address, and ignore this instruction and enter holding state.
And just to start print imaging device time, print imaging device and often need the build-in attribute first obtaining imaging cartridge, therefore the instruction of access fix information can first be sent, such as pass through serial common bus after box chip or disjunctor chip power supply, first send the instruction comprising reference address " 01 ".Below, how the appendage of disjunctor chips 100 and disjunctor chip 200 responds this instruction respectively to divide three kinds of situations to illustrate, suppose that the default priority level of the priority level dispensing unit of the adjunct unit of disjunctor chip 100 is higher, and the default priority level of the priority level dispensing unit of the adjunct unit of disjunctor chip 200 is lower.
The first situation: when disjunctor chip 100 and disjunctor chip 200 are normally connected on serial common bus simultaneously.The appendage of disjunctor chip 100 and disjunctor chip 200 all have received the instruction comprising reference address " 01 " by its interface unit, see Fig. 5, locate in the trailing edge A moment of last clock signal printing imaging device transmission instruction, the OEM box chip of compatibility box chip and original-pack manufacturers produce is generally in this instruction of this time of day response, whether first the response recognition unit of the disjunctor chip 100 that priority level is higher starts to detect on serial common bus has other box chips (may be above-mentioned disjunctor chip, one of OEM box chip of compatibility box chip and original-pack manufacturers produce) respond this instruction, if do not had, then postpone the B moment of a period of time in the A moment to locate, the fix information of the reference address " 01 " that memory cell is stored by its interface unit by the appendage of disjunctor chip 100 first place of the information of addressing " 01 " (represent in Fig. 5 be low level signal) is sent to serial common bus, now print imaging device and can receive this information, if there are other this instructions of box die response, then the control of interface unit release to serial common bus of the appendage of disjunctor chip 100, enters holding state.And the disjunctor chip 200 that priority level is lower, the C moment of response recognition unit after the B moment of its appendage is located, check and whether universal serial bus has other box chips (may be one of OEM box chip of above-mentioned disjunctor chip, compatibility box chip and original-pack manufacturers produce) to respond this instruction, if had (being expressed as low level signal in Fig. 5), then the control of interface unit release to serial common bus of the appendage of disjunctor chip 200, enters holding state; If do not had, then postpone the D moment of a period of time in the C moment to locate, the fix information of the reference address " 01 " that memory cell is stored by its interface unit by the appendage of disjunctor chip 200 first place of the information of addressing " 01 " (represent in Fig. 6 be low level signal) is sent to serial common bus, now print imaging device and can receive this information, as shown in Figure 6.Obviously, because the appendage of the higher disjunctor chip 100 of priority level has responded this instruction, in this case, the appendage of disjunctor chip 200 no longer responds this instruction, and the response condition of disjunctor chip 100 and disjunctor chip 200 as shown in Figure 5.In this process, owing to printing the rising edge of imaging device in next clock signal, the E moment namely in Fig. 5 is located to detect and receives the response signal of disjunctor chip, print the Signal reception of imaging device and the information interaction of subsequent clock period so can not have influence on, the time difference of the present invention's utilization printing imaging device between transmission instruction and reception instruction respond realizes the detection to whether serial common bus there being other these instructions of box die response.
The second situation: when disjunctor chip 200 is normally connected on serial common bus, and the appendage of disjunctor chip 100 is damaged or when being removed.Damaged or when cannot work at appendage, in order to ensure the steady operation of circuit, appendage can be removed from disjunctor chip.Therefore the appendage of disjunctor chip 200 is only had to be have received the instruction comprising reference address " 01 " by its interface unit, the C moment of response recognition unit after the B moment of its appendage is located, check whether serial common bus has this instruction of other box die response, because the appendage of disjunctor chip 100 is damaged or be removed, the C moment remains high level (expression does not have other this instructions of box die response), then postpone the D moment of a period of time in the C moment to locate, the fix information of the reference address " 01 " that memory cell is stored by its interface unit by the appendage of disjunctor chip 200 first place of the information of addressing " 01 " (represent in Fig. 6 be low level signal) is sent to serial common bus, now print imaging device and can receive this information, in this case, the sequential chart that the output signal of the appendage of disjunctor chip 200 is similar to Figure 6.
The third situation: when disjunctor chip 100 is normally connected on serial common bus, and the appendage of disjunctor chip 200 is damaged or when being removed.Similar with the first situation, the appendage of disjunctor chip 100 have received the instruction comprising reference address " 01 " by its interface unit, then locate in the trailing edge A moment of last clock signal printing imaging device transmission instruction, the response recognition unit of its appendage detects on serial common bus whether have other this instructions of box die response, due to the TP top priority that the priority level dispensing unit of the appendage of disjunctor chip 100 is preset, the disjunctor die response not having other herein prints the instruction of imaging device, then postpone the B moment of a period of time in the A moment to locate, the fix information of the reference address " 01 " that memory cell is stored by its interface unit by the appendage of disjunctor chip 100 first place of the information of addressing " 01 " (represent in Fig. 5 be low level signal) is sent to serial common bus, now print imaging device and can receive this information.Locate in C moment and D moment, because the appendage of disjunctor chip 200 is damaged or be removed, these two moment can not change, in this case, and the sequential chart that the output signal of the appendage of disjunctor chip 100 is similar to Figure 5.
The appendage of above-mentioned disjunctor chip, not to be assigned with address of devices to be described.The information of what the memory cell due to appendage stored is different imaging cartridges being common to same printing imaging device, therefore, the address of devices of different imaging cartridge can also be stored in the memory unit, then when receiving the instruction containing address of devices and reference address, can also simultaneously according to address of devices and reference address, identifying whether is the instruction of calling out self, to determine whether to need to send by interface unit the general information self stored.If same information, such as about the information of recording material capacity, addressing in disjunctor chip 100 is " 01 ", and the addressing in disjunctor chip 200 is " 02 ", then must give appendage distribution devices address, and determine to need to send to the information printing imaging device according to address of devices and reference address simultaneously.
In order to remove the appendage of disjunctor chip when needed easily, the method of multiple fixing appendage can be adopted, one method is that appendage or its internal module are made plug-in unit pattern, when encapsulating, be inserted on disjunctor chip, when removing, can extract from disjunctor chip easily.Another kind method as shown in figures 7 a and 7b, the major part of disjunctor chip and appendage are all arranged on two ends on same circuit board (front view see Fig. 7 A disjunctor chip), circuit board between major part and appendage forms a V-arrangement elongated slot (side view see Fig. 7 B disjunctor chip) by machining, then can break deenergizing plate easily when needed, appendage is removed from disjunctor chip.By cutting into groove or the punching of other shapes in the position of V-arrangement elongated slot, also can play similar effect, do not limited at this.
Embodiment two
