Abstract
A process cartridge removably insertable in a body of an image-forming apparatus. The process cartridge has at least one constituent element executing an image formation process, and a non-volatile memory. In the non-volatile memory, data having an identical content are stored at a plurality of mutually spaced locations, the number of which depends on a kind of the data. With respect the locations for the data of an identical content, an address shift amount from one location to another is set according to the kind of the data.
Description
The application is dividing an application of No. 200510076496.1 Chinese invention patent application that is entitled as " handle box that is used for imaging device " submitted to July 24 calendar year 2001.
Technical field
The present invention relates to removably be inserted in the imaging device main body, and have the handle box of the nonvolatile memory that can carry out the imaging process assembly given information relevant with the address with storage.
Background technology
Recent years, to reclaim the natural resources syllabus of deciding, the handle box that removably is inserted in the imaging device main body has begun general.Except for finishing the necessary building block of known electric photograph process, also comprise photosensitive drum, charhing unit, exposing unit, developing cell, clearer and toner reservoir, some these class handle boxes also have a nonvolatile memory, storage is about the information of each handle box.
Publication number is that Fig. 6 of the Japanese patent application of No.2000-19929 has shown the storage map for the EEPROM of nonvolatile memory (electricity can be wiped programmed read-only memory) that is included in the handle box.Find out that obviously the data of identical content are stored in a plurality of addresses from the storage map, each address is spaced from each other to strengthen the reliability of data recording.In addition, because the shift amount (" address shift amount ") between the consecutive storage unit of storage identical data is constant (32 in the above-mentioned storage map), storage and reading of data can be reduced to access program.
But above-mentioned constant address shift amount brings the unhelpful increase of address applications, causes storage efficiency low.Because be difficult to the high capacity internal memory of packing into thereon, and considering cost, is inconvenient to handle box.
Summary of the invention
Therefore, an object of the present invention is to provide a kind of to removably being inserted in the imaging device main body, and has an improvement of the handle box of the nonvolatile memory that can carry out imaging process assembly (as toner reservoir) and contain various information, this improvement makes data be stored in the nonvolatile memory with preferable DATA DISTRIBUTION, and does not have above shortcoming.
In the treatment in accordance with the present invention box, nonvolatile memory a plurality of apart from one another by cell stores have the data of identical content, the number of storage unit depends on the kind of data, a storage unit corresponding to one or more continuation addresses, and for a plurality of storage unit that are used for same data content, according to the address shift amount between a data type storage unit of setting and another storage unit.Allow another data of storage between storage unit in data of a plurality of cell stores that separate.Thereby be stored in that identical data in the different storage unit is unlikely to be damaged simultaneously.And the storage efficiency of nonvolatile memory has also increased.
In one embodiment, the address shift amount of distributing to a plurality of data of different number storage unit in the nonvolatile memory is different.On the other hand, the address shift amount of distributing to a plurality of data of similar number storage unit in the nonvolatile memory is identical.
In nonvolatile memory, the data that are assigned to single storage unit can be stored in and be used for storing second memory unit address address before with same data content.Therefore, even handle box is inserted in the test machine of data ordering rule of the nonvolatile memory that relevant handle box is not installed, before second storage unit that reaches any data of distributing to a plurality of storage unit, this machine only is stored in data the nonvolatile memory by also can read all from first address sequential access.Therefore, just can visit nonvolatile memory with simpler control.
Rewritable data are vulnerable to the influence of the mistake that write operation follows, and risk of errors is low and read-only data is not only owing to can be subjected to the influence of write operation, and its importance or validity degree are also low.Given this, in one embodiment, but the storage unit places that nonvolatile memory separates a plurality of storage has the overwriting data of identical content, but and at number identical or number is less than and is used for storing read-only data (for example indicating a kind of data of handle box) in but all overwriting datas are assigned to the storage unit of storage unit of overwriting data of minimal number storage unit.Therefore, the frequency or the ratio that can take place according to mistake, and importance degree to data map or arrangement effectively, make the data ordering of nonvolatile memory more reliable.
But overwriting data can comprise when the counter data that carries out imaging process interval scale count value with handle box.But overwriting data also can comprise the insertion whether the indication handle box is inserted in the main body of imaging device and detect data, and/or whether the indication handle box is that new new product detects data.The Number of Storage Units that is used to insert the nonvolatile memory that detects data and new product detection data can be less than the Number of Storage Units that is used for counter data, because read the data that insert to detect and new product detect data frequency will be less than the frequency that reads counter data, therefore compare and be difficult for being affected with counter data.
In one embodiment, nonvolatile memory is stored the insertion whether the indication handle box be inserted into the main body of imaging device in turn and is detected data from address at first, indicate the target data of handle box target, indicate the color code data of the image color that forms by handle box.
Handle box with nonvolatile memory of this data ordering makes the control system of imaging device main body side can visit nonvolatile memory, in the following manner the reading of data in turn from first address.At first, control system reads to insert and detects data, to determine whether handle box is present in the main body of imaging device.Whether if exist, control system reads next target data, consistent with the target data of imaging device itself with the intended target of determining handle box.Whether last result indicates handle box to mate with the main body of imaging device.If handle box is determined and the main body of imaging device coupling, then control system reads the color code data to determine whether handle box is placed in the position of imaging device main body (for example, with the position of handle box color-match in).Only after definite handle box is arranged in the position of imaging device main body, determine that just handle box correctly is inserted in the imaging device.After this, the control system of imaging device just allows to start the various handle box Imaging for Control operations that utilize.
Need not have the data form of memory access non-volatile memory addresses order from the control system that above is appreciated that the imaging device side, but allow from sequential access non-volatile memory addresses at first.Therefore, by the control system of imaging device, the data ordering in this nonvolatile memory can be simplified about the control to its visit.This also is true when handle box is inserted in the test machine before the transportation handle box or after recovery or returning handle box.
Be the handle box target that obtains carefully being detected, by the address order, target data can comprise that indication is by the transportation target data of the destination of geographic classification and the OEM code data of indicating the original equipment manufacturing producer (OEM) that makes handle box.
Generally need be prior to other controls, to obtain color balance with other handle boxes that are placed in the imaging device main body to imaging operation to the Auto-regulating System of Density of Heavy Medium of handle box.In one embodiment, in order to satisfy this needs, whether the indication handle box is contained at the place, an address after the address of nonvolatile memory stores color code data is that new new product detects data.The control system of imaging device but read the color code data only after having determined that nonvolatile memory has correctly been inserted before starting the imaging operation control that utilizes handle box.When having determined that handle box is new, starting before utilizing the handle box Imaging for Control, allow handle box is carried out Auto-regulating System of Density of Heavy Medium.
For ease of making handle box, at least one element of handle box can comprise photosensitive unit, charging equipment, the clearer that comprises photosensitive drum and comprise developing apparatus and the developing cell of toner reservoir.
From following description, can understand other purposes, performance and advantage of the present invention.

Fig. 8 has shown the example of the storage map of the EEPROM20 that adds in each handle box 9.In table shown in Figure 8, field name is called " address " and refers to the address that the sign indicating number that wherein forms with two bytes is stored data, " data name " refers to the data name that will store (or having stored), " initial value " refers to the value of being stored when factory transports, and " data type " refers to the data that will store (or having stored) and whether only be read-only data or overwriting data.
Can find out obviously that from the storage map data of storage are divided into read-only data, be called the data of " color code " and " lot number ", and overwriting data, be called the data of " developer roll counter " and " photosensitive drum counter " as name as name.
Whether " insert and detect " data refers to handle box 9 and has been inserted in the printer main body 5." new product detection " data refer to whether handle box 9 is new." transportation target " data refer to the area, destination that handle box 9 is transported, as Japan, and North America etc." OEM code " data refer to the OEM (original paper equipment manufacturers) that makes handle box 9.That is, " OEM code " data refer to the buyer who sells handle box 9 under the trade mark at handle box 9." color code " data refer to the color of image (Huang, product, green grass or young crops, black) that is formed by handle box 9." lot number " data refer to the lot number of handle box 9.Each " recovery number " data refers to the reservation number of recycling box 9." TC history " data refer to the ratio history of toner and carrier in the developing cell 103 of handle box 9." ADTC sensor shift value " data refer to the controlled quentity controlled variable that the developing cell 103 of handle box 9 is exported about the ADTC sensor." developer roll counter " data refer to the number of the developing cell 103 that uses handle box 9." photosensitive drum counter " data refer to the number of the photosensitive drum 111 that uses handle box 9.
Read-only data with identical content is not stored in a plurality of addresses of storer, but is stored in the address.On the other hand, according to access times and significance level, the overwriting data with identical content is stored in a plurality of addresses of spaced-apart storer.When data are stored in the continuation address, think that data storage is in a storage unit.According to following rale store data.
(a) identical data that will have big access times and high level importance is stored in 3 spaced-apart storage unit.For example, the value of " developer roll counter " is stored in address 23-24, in 3 storage unit of address 48-49 and address 59-60.Similarly, the value of " photosensitive drum counter " is stored in address 25-26, in 3 storage unit of address 50-51 and address 61-62.
(b) identical data that will have Average visits and average degree importance is stored in 2 spaced-apart storage unit.For example, the result who " inserts and detect " is stored in 2 storage unit of address 0 and address 40.Similarly, the result of " new product detection " is stored in 2 storage unit of address 1 and address 41.
(c) identical data that will have low access times and low degree importance is stored in 1 storage unit.For example, " TC history " only is stored in 1 storage unit of address 21.Similarly, " ADTC sensor shift value " data only are stored in 1 storage unit of address 22.
Tabular shown in Figure 9 has gone out rule-based (a)-(c), according to each memory of data Number of Storage Units of access times and importance degree.
According to rule (a)-(c), according to producing wrong frequency and significance level array data effectively in EEPROM20.Therefore, EEPROM20 has a preferred data ordering.
(d) in a plurality of different pieces of informations that are stored in spaced-apart similar number storage unit respectively, its address shift amount is identical.For example, for " developer roll counter " data that are stored in 3 storage unit respectively and " photosensitive counter " data, second storage unit (address 48-49, address 50-51) to (the address 23-24 of first storage unit, address 25-26) the address shift amount is both 25, the 3rd storage unit (address 59-60, address 61-62) is both 11 to (address 48-49, address 50-51) address shift amount of second storage unit.For " insert and detect " data and " new product detection " data that are stored in 2 Memory Storage Units respectively, second storage unit (address 40, address 41) is both 40 to (address 0, address 1) address shift amount of first storage unit.
(e) in the different data of Number of Storage Units, its address shift amount is different mutually.For example, for " developer roll counter " data that are stored in 3 storage unit respectively and " photosensitive counter " data, the address shift amount of first and second storage unit is that the address shift amount of the 25, the second and the 3rd storage unit is 11.These address shift amounts are different with " insert and detect " data that are stored in 2 storage unit respectively and the address shift amount 40 of " new product detection " data.
(f) be stored in the data in the storage unit, promptly, read-only data, as " purpose " data and " OEM " data, and some overwriting datas, be stored in prior in the address that is stored in second address in a plurality of storage unit as " TC history " data and " ADTC sensor shift value " data with identical content.For example, " purpose " data, " OEM " data, " TC history " data and " ADTC sensor shift value " data are stored in respectively in the address 2,3,21,22.The sequence number of these addresses 2,3,21,22 is less than second address 40 that is stored in the sequence number minimum with identical content in a plurality of addresses (second addresses of " insert and detect " data).
(g) the address sum that exists between the consecutive storage unit of storage data is bigger than the address number that is used to store given number of memory cells purpose other data different with the first mentioned data.Its objective is other data are placed between the first adjacent data storage cell.
Figure 10 example according to the rule (d)-(g) the data ordering example.The cubic frame of Figure 10 homeotropic alignment refers to the data of placing by sequence of addresses, and the numeral before each cubic frame hyphen refers to the number of the storage unit of storage identical data.Numeral after each cubic frame hyphen refers to the sequence number of identical data.For example, the indication of topmost " 2-1 " has referred to two storage unit to data allocations, and data storage is among first of two storage unit." 2-1 " " 1-1 " afterwards referred to a storage unit to data allocations, and data storage is among single storage unit." 1-1 " " 3-1 " afterwards referred to three storage unit to data allocations, and data storage is among first of three storage unit.
According to rule (d)-(g), be stored in and placed other between the identical data of a plurality of storage unit and have certain number of memory cells purpose data.With reference to data ordering shown in Figure 10, data " 1-1 " and " 3-1 " are placed between identical content data " 2-1 " and " 2-2 ", and data " 2-2 " place between the data " 3-1 " and " 3-2 " of identical content.Therefore, the data " 3-1 " of the data of identical content " 2-1 " and " 2-2 " and identical content and possibility that " 3-2 " damaged simultaneously are very little.
In addition, strengthen the storage efficiency of EEPROM and to place data in EEPROM 20 effectively be possible.For example, in storage map shown in Figure 8, only need 63 sign indicating numbers, and in traditional storage map, need 127 yards.
And, because set up the rule of array data among the EEPROM 20, can simplify the access program of storage and reading of data.Particularly, according to rule (f), even handle box 9 (for example is positioned in machine that EEPROM20 do not import the array data rule, used detection machine after transporting handle box 9 or reclaiming it) in, can pass through from the first address reference address, be stored in visit before the data of identical content of many places, need not to repeat to read identical data and just can read all data that are stored among the EEPROM 20.Therefore, can simplify visiting the control of EEPROM 20.
Figure 11 A-11D example the data exchange mode between printer main body 5 (more specifically, control panel 26) and the handle box 9.Figure 11 A has shown the exchanges data as " the developer roll counter " of the example that is stored in 3 overwriting datas in the storage unit.Figure 11 B has shown the exchanges data as " the new product detection " of the example that is stored in 2 overwriting datas in the storage unit.Figure 11 C has shown the exchanges data as " the TC history " of the example that is stored in 1 overwriting data in the storage unit.Figure 11 D has shown the exchanges data as " the transportation target " of the example that only is stored in 1 read-only data in the storage unit.Under arbitrary above-mentioned situation, printer main body 5 sends control (request) signal by serial transmission bus Tx and gives handle box 9, receives the back-signalling of request signal from handle box 9 by serial received bus Rx.
Hereinafter will describe the controlled step of exchanges data (shown in Figure 11 A-11D) in detail, the storage map of supposing EEPROM 20 as shown in Figure 8.
With reference to Figure 12, in the control for " developer roll counter " exchanges data, determine in step 101 whether the request of being accepted is " writing " request or " reading " request.If the request of accepting is " writing " request, in step S102, set be used for storage " developer roll counter " data write address 23, in step S103, to carry out write operation.In step S104, obtain address 48 by increasing address shift amount 25 for address 23, set it and in S105, carry out write operation for writing the address.After this, in step S106, obtain address 59, set it and in S107, carry out write operation for writing the address by increasing address shift amount 11 for address 48.On the other hand, be " reading " request if determine the request of accepting in step S101, setting one is specified and is read the address in step S111.In step S112, carry out the read operation of a continuous read operation or a sign indicating number, read address reading data in appointment.In step S113, reading of data is set in the transmission buffer (not shown), and reading of data is sent in the printer main body 5.Then, by serial transmission bus Tx reading of data is sent to printer main body 5 from handle box 9.
With reference to Figure 13, in the control to " new product detection " exchanges data, differentiating the content that accepts request in step 121 is " writing " request or " reading " request.If the request of accepting is " writing " request, in step S122, set be used for storage " new product detection " data write address 1, in step S123, to carry out write operation.In step S124, obtain address 41 by increasing address shift amount 40 for address 1, set it for writing the address in S125, to carry out write operation.On the other hand, be " reading " request if determine the request of accepting in step S121, setting one is specified and is read the address in step S131.In step S132, carry out the read operation of a continuous read operation or a sign indicating number, read address reading data in appointment.In step S133, reading of data is set in the transmission buffer (not shown), is used for reading of data is sent to printer main body 5.Then, by serial transmission bus Tx reading of data is sent to printer main body 5 from handle box 9.
With reference to Figure 14, in the control to " TC history " exchanges data, differentiating the request content of accepting in step 141 is " writing " request or " reading " request.If the request of accepting is " writing " request, in step S142, set be used for storage " TC history " data write address 21, in step S143, to carry out write operation.On the other hand, be " reading " request if determine the request of accepting in step S141, setting one is specified and is read address (being 21 in this case) in step S151.In step S152, carry out the read operation of a continuous read operation or a sign indicating number, read address reading data in appointment.In step S153, reading of data is set in the transmission buffer (not shown), is used for reading of data is sent to printer main body 5.Then, by serial transmission bus Tx reading of data is sent to printer main body 5 from handle box 9.
With reference to Figure 15, in control,, need not determine that the content that accepts request is " writing " request or " reading " request because " transportation target " data are read-only datas to " transportation target " exchanges data.In a single day therefore accepted to write request, in step S161, set an appointment and read address 2.In step S162, carry out the read operation of a continuous read operation or a sign indicating number, read address reading data in appointment.In step S163, reading of data is set in the transmission buffer (not shown), is used for reading of data is sent to printer main body 5.Tx sends to printer main body 5 with reading of data from handle box 9 by the serial transmission bus.
Figure 16 has shown the example of another storage map among the EEPROM20 that joins each handle box 9.Be similar to storage map shown in Figure 8, read-only data is not stored in a plurality of storage unit, but only is stored in the storage unit.On the other hand, according to its access times and significance level, the overwriting data with identical content is stored in spaced-apart a plurality of storage unit.And, be similar to the storage map of Fig. 8, if data are stored in the continuation address, this continuation address is considered to a storage unit.
To be " insert detect " data, " transportation target " data, " OEM code " data, " color code " data and " new product detection " data be stored at first address 0 in address 4 according to this order to the feature of storage map shown in Figure 16.
Whether Figure 17 has shown the master routine of the process of coming out that CPU27 (being included in the control panel 26 of printer main body 5) will carry out, correctly be arranged on or be inserted in the printer main body 5 to detect handle box 9Y, 9M, 9C and 9K.
When opening power, in step S201, whether the EEPROM of the program jump processing procedure of CPU27 detection of stored CPU27 (a kind of nonvolatile memories that not show different with EEPROM20) is present in the printer main body 5.If EEPROM does not exist, can determine to have taken place problem.Therefore do not carry out processing procedure subsequently.
Sensor SE16 as shown in figure 13 detects when EEPROM is present in the printer main body 5, and the protecgulum of printer main body 5 is a closed condition from its open mode process, at step S202- S205 handle box 9Y, 9M, 9C and 9K is handled.
Figure 18 and 19 has shown each handle box 9Y, 9M, the detailed process flow process (step S202-S205) of 9C and 9K.Processing procedure shown in the general execution flow process is used for the EEPROM20 of each handle box 9Y, 9M, 9C and 9K, and parallel mutually, and the program of Chong Fuing turns back in the master routine shown in Figure 17 and (after this only is called " returning ") simultaneously.In S221, the processing procedure of carrying out the EEPROM of printer modes 5 walks abreast with the EEPROM20 that carries out each handle box 9Y, 9M, 9C and 9K at step S211.But for convenience, the processing procedure of the EEPROM20 of performed each handle box 9Y, 9M, 9C and 9K will be in following description.
With reference to Figure 18, open when the protecgulum of in step S210, determining printer modes 5, setting variable " state (state) " in step S240 is 1, program is returned.
Closing in case determine the protecgulum of printer modes 5, is first address of visit EEPROM20, distributes to " adr (address) " that variable is indicated the address with 0 in step S211.Program is returned then.
In next process, in step S212, data Aah is write to address " adr " and address " adr+40 ", setting variable " state (state) " at step S213 then is 2, program is returned.
In next process,, determine whether reading of data is Aah in the data that step S214 reads address " adr " and address " adr+40 ".If the data that " adr " and address " adr+40 " reads from the address are not Aah, just can determine in printer main body 5, not exist EEPROM20.Then in step S215, CPU27 notification controller 25, EEPROM20 in printer main body 5 (that is, handle box 9) does not exist, or is not inserted into.Setting variable " state " at step S216 is that program is returned after 0.When not having EEPROM20 in definite printer main body 5, can not be further processed, as read primary data and write data EEPROM20.If determine that in step S214 at least one data that " adr " and address " adr+40 " reads from the address are Aah, just can determine in printer main body 5, to exist or inserted EEPROM20.Then in step S217, the processing procedure that is stored in all data among the EEPROM20 is read in the CPU27 startup continuously.All reading of data are stored among the RAM29 of control panel 26.Then, setting variable " state " at step S218 is that program is returned after 3.
If determining to read all data in step S219 does not finish, variable in step S221 " adr " increases by 1 (being designated as " adr++ " in the drawings), program is returned on the other hand then, finish if determine to read all data at step S219, setting variable " state " at step S220 is 4.Increase variable " adr " afterwards at step S221, program is returned.All data of storing among the EEPROM20 in the method, are stored among the RAM29 of control panel 26.
At this moment, in RAM29, carry out the address mapping identical with EEPROM20.Therefore, below mention " in the address * * * data " equal from EEPROM20 identical address * * * data that read.
With reference to Figure 19, in next process, " transportation target " data consistent whether " transportation target " data of determining in the address " adr " at step S222 read with EEPROM from printer main body itself.Thus, but judgment processing box 9 whether with printer main body 5 couplings.For example, if the transportation target of handle box 9 is Europe, and the transportation target of printer main body 5 is a Japan, can determine that handle box 9 and printer main body 5 do not match.In this case, at step S223CPU27 notification controller 25, handle box 9 is inserted in the printer main body 5 mistakenly.Then, after step S224 was set at 0 with variable " state ", program was returned.When having determined that handle box 9 has been inserted by mistake, that is, handle box 9 is wrong handle boxes, can not become closed condition until the protecgulum of finding printer main body 5 from open mode to the EEPROM20 visit of this handle box 9.On the other hand, if determine that at step S222 " transportation target " data of address " adr " and " transportation target " data of printer modes 5 are consistent mutually, variable " state " is set at 5 at step S225.Then, increase variable " adr " in step S226, program is returned.
In next process, " OEM code " data consistent whether " OEM code " data of determining in the address " adr " in step S227 read with EEPROM from printer main body itself.Thus, but judgment processing box 9 whether with printer main body 5 couplings.If determine that at step S227 " OEM code " data of " OEM code " data of address " adr " and printer main body 5 are inconsistent mutually, promptly, if determining handle box 9 and printer main body 5 does not match, at step S223CPU27 notification controller 25, handle box 9 is inserted into mistakenly or is placed in the printer main body 5, and is the same with the processing of carrying out in the last process.Then, after step S224 was set at 0 with variable " state ", program was returned.When having determined that handle box 9 has been inserted into by mistake in the printer main body 5, can the EEPROM20 of this handle box 9 not conducted interviews, become closed condition until the protecgulum of finding printer main body 5 from open mode.If determine that at step S227 " OEM code " data that " OEM code " data of address " adr " and EEPROM from printer main body itself read are mutually consistent, variable " state " be set at 6 at step S228.Then, increase variable " adr " in step S229, program is returned.
In next process, determine at step S230 whether " color code " data of address " adr " are consistent mutually with " color code " data of inserting handle box position (Huang, product, green grass or young crops and black position) from printer 5.Color code 1 is corresponding to blue or green (C), and 2 corresponding to product (M), and 4 corresponding to yellow (Y), and 8 corresponding to black (K).If for example " color code " data of address " adr " are 1 of indication cyans (C), and " color code " data that printer 5 inserts the handle box position are 2 of indication product looks (M), can determine that handle box 9 is not placed in the tram of printer main body 5.Promptly, if determine that " color code " data of address " adr " are inconsistent mutually with " color code " data of inserting the handle box position from printer 5, then handle box 9 is not placed in the tram of printer main body 5, at step S223 CPU 27 notification controllers 25, handle box 9 is inserted in the printer main body 5 mistakenly then.Then, after step S224 was set at 0 with variable " state ", program was returned.When having determined that handle box 9 has been inserted into by mistake in the printer main body 5, can the EEPROM20 of this handle box 9 not conducted interviews, become closed condition until the protecgulum of finding printer main body 5 from open mode.On the other hand, if determine that at step S230 " color code " data of address " adr " are consistent mutually with " color code " data of inserting the handle box position from printer 5, promptly, determined that handle box 9 is placed in proper position, can determine for the first time that then handle box 9 is correctly inserted and settles.Therefore, at step S231 variable " state " is set at 7, increases variable " adr " at step S232, at step S232 CPU27 notification controller 25, handle box is correctly inserted.Program is returned then.When having determined that handle box 9 is correctly settled, allow 9 visits of this handle box are opened until printer main body 5.Therefore, the controller 25 of printer main body 5 can start using handle box 9 Imaging for Control now.
For example in next process, whether whether reading indication handle box 9 at step S234 is new " new product detections " data, be new with definite handle box 9.If the value of " new product detection " is neither 4Bh neither FFFFh, and then handle box 9 is not new, and if the value of " new product detection " is 4Bh or FFFFh, then handle box 9 is new.If handle box 9 is not new, setting variable " state " at step S236 is 0.Program is returned then.If handle box 9 is new, CPU27 notification controller 25 handle box handle boxes 9 are new.After this, after step S236 setting variable " state " was 0, program was returned.This allows to finish the Auto-regulating System of Density of Heavy Medium of handle box 9 before carrying out other imaging control.Therefore, the color of handle box 9 can with the color balance of other handle box 9.
From above understanding, by carrying out simple control, CPU27 can determine that whether handle box 9 is by correct being inserted in the printer main body.This is because according to the present invention, the EEPROM20 of handle box 9 contains " insert and the detect " data at 0 place, address at first in turn, at next address 1 place as " the transportation target " of destination data, next address 2 places also as " the OEM code " of destination data with in the data " color code " at next address 3 places.Promptly, because the storage map of the EEPROM20 of handle box 9 shown in Figure 16, even do not use the tabulation of the address order information that contains the EEPROM20 that will visit, increase variable adr by first address, can obtain detecting handle box 9 and whether be set correctly information required in printer main body 5 from the EEPROM20 of handle box 9.Therefore, do not need to prepare such tabulation.
In addition, when before transportation handle box 9 and/or after regaining or reclaiming it, when handle box 9 was installed on the used detection machine, the control system of detection machine allowed the EEPROM20 from the first address sequential access handle box 9.That is, detection machine can detect handle box 9, and need not to use the tabulation of the address order information that contains the EEPROM20 that will visit.Therefore, do not need to prepare such tabulation.
Figure 20 has shown an alternative flow process of the detailed process of processing handle box 9Y, 9M, 9C and 9K shown in Figure 19 (will carry out) in step S202-S205 in Figure 17.In this example, also to carry out the processing procedure of step S210 shown in Figure 180 to step S221.That is, still to combine execution to the used data of storage EEPROM among the RAM29 of control panel 26 with the step among Figure 20 from the state procedure of protecgulum from the open mode to the closed condition that detects printer main body 5.
With reference now to Figure 20,, after reading used data, determines at step S322 whether " transportation target " data that " transportation target " data of address " adr " and EEPROM from printer main body 5 read are consistent mutually.Find thus whether handle box 9 and printer main body 5 mate.If determine that at step S322 " transportation target " data that " transportation target " data of address " adr " and EEPROM from printer main body 5 read are consistent mutually, in step S323, increase variable " adr ".
Subsequently, determine in step S324 whether " OEM code " data that " OEM code " data of address " adr " and EEPROM from printer main body 5 read are mutual consistent.Find thus whether handle box 9 and printer main body 5 mate.If determine that at step S324 address " adr " is consistent mutually with " OEM code " data from printer main body 5, can determine handle box 9 and printer main body 5 couplings.In step S325, increase variable " adr " then.
Whether " color code " data of determining address " adr " then in step S326 are mutual consistent with " color code " data from the insertion handle box position (that is, Huang, product, blue or green and black position) of printer main body 5.Find thus whether handle box 9 and printer main body 5 mate.If it is consistent mutually that " color code " data of address " adr " and printer 5 inserts " color code " data of handle box positions, thereby handle box 9 is placed in proper position, can determine that then handle box 9 is correctly inserted.Therefore, increase variable " adr " at step S327, at step S238 CPU27 notification controller 25, handle box 9 is correctly inserted then.Program is returned then.Correctly inserted in case determined handle box 9, allowed EEPROM 20 visits, opened until the protecgulum of printer main body 5 to this handle box 9.Therefore, the controller 25 of printer main body 5 can start using the various control operations of handle box 9 imagings.
For example, whether are new " new product detections " data, to determine indicating whether handle box 9 is new if reading indication handle box 9 at step S329.If handle box 9 is not new, setting variable " state " at step S331 is 0.Program is returned then.On the other hand, if handle box 9 is new, at step S330CPU27 notification controller 25, handle box 9 is new.This allows to finish the Auto-regulating System of Density of Heavy Medium to handle box 9 before imaging being carried out other control.Therefore, the color of handle box 9 can with the color balance of other handle box 9Y, 9M, 9C and 9K.
On the other hand, if " transportation target " data of determining address " adr " at step S322 are with inconsistent mutually from " transportation target " data of printer main body 5, then correspondingly handle box 9 does not match with printer main body 5, CPU 27 notification controllers 25 in step S332, handle box 9 is inserted in the printer main body 5 mistakenly.Similarly, if step S324 determines that " OEM code " data of address " adr " " OEM code " data and printer main body 5 are inconsistent mutually, then correspondingly handle box 9 does not match with printer main body 5, CPU 27 notification controllers 25 in step S332, handle box 9 is inserted in the printer main body 5 mistakenly.Similarly, if it is inconsistent mutually that step S326 determines that " color code " data of address " adr " and printer main body 5 insert " color code " data of handle box positions, then correspondingly handle box 9 is not placed on correct position, CPU 27 notification controllers 25 in step S332, handle box 9 is inserted in the printer main body 5 mistakenly.When CPU 27 notification controllers 25, when handle box 9 was inserted in the printer main body 5 mistakenly, setting variable " state " at step S331 was 0, and program is returned.When having determined that handle box 9 is inserted by wrong, can the EEPROM20 of this handle box 9 further not visited, become closed condition until the protecgulum of finding printer main body 5 from open mode.
In having this example of Figure 26 flow process, the same with the example of front, by carrying out simple control, CPU27 can determine also whether handle box 9 is correctly inserted or be arranged in the printer main body 5.In addition, the example of Figure 20 flow process needed step still less than Figure 19 flow process example before determining handle box 9 correct insertions.Therefore, this deterministic process can be carried out sooner.
In described example, handle box 9 has photosensitive drum 111, charhing unit 101, exposing unit 102, developing cell 103, clearer 116 and toner storer also have the EEPROM 20 as nonvolatile memory in addition as the element that forms illustration method.But handle box of the present invention is not restricted to this pattern.Be to be understood that any handle box includes in scope of the present invention, as long as it has any as the element that forms illustration method.For example, the exposing unit to the photosensitive drum face exposure can be fixedly installed on the shell of printer main body.In this case, photosensitive drum, charhing unit and clearer can be integrated into together as photosensitive unit, and developing cell and toner reservoir can be integrated into together as developing cell.The blocking of this element makes the manufacturing handle box simple.
Equally, should be appreciated that the handle box that only has nonvolatile memory and toner storer is included in the scope of the present invention.When using such handle box, other assembly, promptly photosensitive drum, charhing unit, exposing unit, developing cell and clearer can be fixed on the printer main body.In addition, above-mentioned other assembly can make the box that removably is placed in the printer main body.
In addition, in described example, the EEPROM20 that handle box 9 contains is the example as nonvolatile memory.But handle box of the present invention can have the nonvolatile memory that is different from EEPROM.And nonvolatile memory does not need must be included in the shell of handle box, but can be connected in the outside surface of handle box shell by the sleeve pipe that is arranged on its outside surface yet.
The present invention describes like this, but apparent, this invention can have the variation of multiple mode.As long as this variation is considered to not depart from the spirit and scope of the invention, then to those skilled in the art, all these change thinks apparently and is included in the scope of following claim.
