When image processing system 10 was used as printer, image processing system 10 formed image based on the data of view data that is provided by main frame HC and setting in image processing system 10 on printing paper.
As shown in Figure 1, image processing system 10 has and is arranged in three paper feeding disks 111,112 and 113 of three layers, wherein is respectively arranged with printing paper 121,122 and 123.For example, printing paper 121 and 122 can be a common paper, and printing paper 123 can be the printing paper with electronic tag 33.Corresponding to paper feeding disk 111,112 and 113, be provided with feed roll 131,132 and 133 respectively, and, be provided with conveying roller 141,142 and 143 respectively corresponding to feed roll 131,132 and 133.By this structure, printing paper 121,122 and 123 can pass through feed roll 131,132 and 133 respectively, is transported to printing element 20 by conveying roller 141,142 and 143 then.
In printing element 20 (that is, the print engine in the present embodiment), the surface of photosensitive drums 21 is recharged roller 22 uniform charging.Electric charge on the photosensitive drums 21 is optionally eliminated to form electrostatic latent image by laser beam LB, afterwards by developer 23 transmit toners to the live part of photosensitive drums 21 with developing electrostatic latent image.
After photographic fixing was handled, printing paper was discharged on the paper disc 15 by exit roller 145 and after-treatment device 16.Be provided for detecting the grate paper-arranaging sensor 17 of discharging printing paper near the exit roller 145.
The scanner 32 that is arranged on document board 31 belows is used to scan the image on the original copy that is placed on the document board 31.
As shown in Figure 2, printing paper 123 has the electronic tag 33 that is attached to its edge.
In addition, as shown in Figure 1, label reader 34 is arranged near the document board 31, and it need not contact the content that just can read in the electronic tag 33 that is stored in printing paper 123.Label register 35 is arranged on the paper transportation path before the printing element 20, and when forming coding pattern on printing paper 123, it can be written to unique code 50 and the corresponding code 51 of coded key (referring to Fig. 2) in the electronic tag 33.Here, size and the effective coverage that is used for reading or writing the radio wave of electronic tag 33 according to image processing system 10 from electronic tag 33, label reader/register can also be arranged on same position, rather than make label reader 34 be separately positioned on different positions with label register 35.
The corresponding code 51 of unique code 50 and coded key uses in decoding schema.Unique code 50 is used for determining whether image processing system 10 is suitable for being formed at the coding pattern decoding on the original copy 12 that is placed on the document board 31.The corresponding code 51 of coded key is used for determining whether the decoding key from 44 inputs of operation input unit is suitable.The corresponding code 51 of coded key is consistent with coded key, and comprises the coded data of encoding and generating by to coded key.
In order to control the internal element of image processing system 10, image processing system 10 has system controller 40.System controller 40 and scanner 32, label reader 34, label register 35, image data memory 41 (comprising the service area), data storage 42, unique data memory 43, operation input unit 44, conveying roller controller 45 and printing element controller 46 are set are connected.
Before using the document protection function of image processing system 10, the user should operating operation input unit 44, and the printing paper that will have an electronic tag is set in paper feeding disk 111,112 and 113.Fig. 3 and Fig. 4 show the function screen that is used for this setting.These function screens are presented on the touch panel of image processing system 10.
In Fig. 3, drawing reference numeral 1,2 and 3 is identiflication numbers of paper feeding disk, is equivalent to the paper feeding disk 111,112 and 113 shown in Fig. 1 respectively.In the label of representing paper feeding disk 111,112 and 113 respectively was each coffin of 1,2 and 3, the size of printing paper, direction and type were based on being stored in the data representation that is provided with in the data storage 42.This specific embodiment shows such situation, the setting that changes paper feeding disk makes paper feeding disk 3 load the vertical printing paper of A4 of having electronic tag, and in initial setting up, paper feeding disk 1 and 3 dresses be the vertical common paper of A4, and paper feeding disk 2 dress be the A3 size laterally utilize paper again.
When selecting the coffin 3 of expression paper feeding disk 113 by touch, selected part will be highlighted demonstration (in Fig. 3, this part is with the box-shaped pattern displaying), and demonstrate the drop-down menu that comprises size, direction and the type that will be placed to the printing paper on the paper feeding disk 113.When the coffin 3 that touches once more corresponding to paper feeding disk 113, drop-down menu will disappear, and show and will turn back to initial condition (this order is identical with other selection operations).When selecting the type of printing paper in the screen shown in Fig. 3, selected part will be highlighted demonstration, and as shown in Figure 4, will show the more drop-down menu of next stage.In fact, the type of printing paper has how possible selection, and still for the description of simplified embodiment, Fig. 4 only shows three kinds of options.In Fig. 4,, will become " tape label common paper " corresponding to " common paper " in the coffin 3 of paper feeding disk 113 expression so if selection is the tape label common paper.Data are set will temporarily store in the service area of memory by what this operation was set up.When " OK " in for example touch screen upper right corner button, data are set will be transferred to from the service area data storage 42 is set, thereby upgrade data are set.
Main frame HC shown in Fig. 1 is equipped with the printer driver PD that is used for image processing system 10.When printer driver PD moves, will show the print setting dialog frame, when selecting one of them label, with show as shown in Figure 5 be used to be provided with document protection function operations screen.
Under the situation that text code is printed then, the document protection function can be opened by using pointing device sensing and click radio button " ON ", or in other cases, can the document protection function be closed by pointing to and click radio button " OFF ".
When " printing " button shown in touch Fig. 5, comprise that the view data of setting of printing data will be transferred to system controller 40 from main frame HC.After system controller 40 receives image, will temporarily store data in the image data memory 41.
Fig. 6 shows when as mentioned above after image data storage is in the image data memory 41, the flow chart of the processing of being implemented by system controller 40.
In step S0, the content of system controller 40 check image data storages 41 is opened or is closed to determine the document protection function.When confirming that the system protection function is closed (among the step S0 not), system controller 40 enters step S1, perhaps, when confirming that the document protection function is opened (being among the step S0), enters step S2.
In step S1, system controller 40 is carried out and the irrelevant conventional print procedure of document protection function, termination then.
In step S2, system controller 40 uses random digit systematic function etc., generates the corresponding code 51 of coded key and coded key automatically.And system controller 40 generates decoding key based on the coded key that generates in this step.
In step S3, system controller 40 by for example triple des (data encryption standard) system to being stored in the digital coding in the image data memory 41, then, system controller 40 is transferred to printing element controller 46 as code string together with the pattern transfer instruction with view data.
In step S4, in response to code string and pattern transfer instruction from system controller 40 transmission, printing element controller 46 converts each code in the code string (for example, each 4 code) to predetermined little pattern.For example, as shown in Figure 7,4 hexadecimal codes " 0 "～" F " is converted into little pattern 520～52F respectively.Dotted line in the little pattern of shown in Fig. 7 each is convenient to understand little pattern, and has shown non-printing.Each little pattern all is 5 * 5 dot patterns, and wherein the point around outermost is used to distinguish the border between each adjacent little pattern, and does not comprise stain.In 5 * 5 matrixes, 126 kinds of modes of arranging any four points are arranged, wherein the pattern of 16 kinds of very difficult misclassifications is used as these little patterns.
In step S5, system controller 40 uses conveying roller controller 45 to begin to transmit the printing paper of selecting in the paper feeding disk 113 123, and, on electronic tag 33, be written in unique code 50 and the corresponding code 51 of coded key that generates among the step S2 by label register 35 in the predetermined moment.
In step S6 and S7, printing element controller 46 makes laser beam LB scanning photosensitive drums 21 simultaneously by the Kai Heguan based on little pattern array view data control laser beam LB, forms the electrostatic latent image of little pattern array image on photosensitive drums 21.On the other hand, based on state information that receives from printing element controller 46 and the information that receives from the printing paper transducer, system controller 40 makes supply unit pass through conveying roller controller 45 and drives.To second page and afterwards page or leaf, provide not the printing paper of tape label to be used for printing.When being completed for printing of all pages (being among the step S7), system controller 40 will enter step S8.
By processing described above, can produce document through coding.
In step S8, the decoding key that system controller 40 will generate in step S2 is sent to main frame HC.In response to the transmission of decoding key, the Email that printer driver PD will comprise the text of decoding key sends to predetermined address.
Fig. 8 is the pattern diagrammatic sketch that is illustrated in the image of the original copy 12 that prints out in the coding mode.
Fig. 9 shows the flow chart of the processing of being implemented by system controller 40.These processing will begin by the duplicating start button in the push input unit 44.
In step S10, system controller 40 control is read content in the electronic tag 33 that is stored in the original copy 12 that is placed on the document board 31 by label reader 34.If be included in the unique code 50 in the content of reading be stored in unique code in the unique data memory 43 inconsistent (among the step S10 not), then system controller 40 enters step S11, perhaps, if unique code 50 consistent with the unique code in being stored in unique data memory 43 (being among the step S10), system controller 40 will enter step S12.
In step S11, system controller 40 is controlled at and shows on the display screen of operation input unit 44 and show that this original copy is unsuitable for the information with image processing system 10 decodings, and sends electronics buzz, termination then.
In step S12, system controller 40 prompting users are by operation input unit 44 input decoding keys.In response, the user imports decoding key, and touches " affirmation " button (not shown).
In step S13, system controller 40 response users' input is encoded to decoding key, and determines whether their corresponding codes 51 with coded key mate.When finding not match (among the step S13 not), system controller 40 enters step S14, and maybe when finding to mate (being among the step S13), system controller 40 enters step S15.
In step S14, system controller 40 controls show that the information that input error is arranged is presented on the display screen of operation input unit 44, returns step S12 then.
In step S15, system controller 40 gated sweep devices 32 are read the image on the original copy 12.
In step S16, based on the corresponding relation between little pattern and the hexadecimal code, system controller 40 converts each the little pattern (referring to Fig. 7) in the little pattern string of the view data of reading to hexadecimal code.In addition, the correspondence between little pattern and the hexadecimal code is controlled in advance by system controller 40.
In step S17, system controller 40 controls will be through the code decoding of conversion by the use decoding key, thereby recover the view data with the PDL description, system controller 40 control image restored data temporarily are stored in the presumptive area in the image data memory 41 then.
In step S18, based on the view data and the content that is provided with in the data storage 42 that are stored in the image data memory 41, system controller 40 control conveying roller controllers 45 and printing element controller 46 are carried printing paper, form image then on printing paper.
As mentioned above, according to embodiments of the invention, because original copy is converted into coding pattern, even original copy is forgotten on the document board of image processing system or other place unfortunately, the secret that also can prevent to be documented on the original copy is leaked.And according to this embodiment, in decoding schema, image form to be handled and will can not carried out, unless the corresponding code of the decoding key of user's input and the coded key of reading from the electronic tag 33 that is attached to coded document 12 51 is consistent.Therefore, can prevent from owing to the decoding key of input error on printing paper, to carry out unwanted picture and form, and therefore can prevent to infer coded document owing to misplacing printed original.
And, according to embodiments of the invention, in decoding schema, before the user imports decoding key, unique code 50 is read from the electronic tag 33 that is attached to coded document 12, and determining this unique code 50 and be stored in unique data in the unique data memory 43 when inconsistent that the notice user's set does not match.Therefore, the user can determine promptly whether image processing system is suitable for decoding, and therefore can save unnecessary time and effort in attempting decode procedure.
In addition, consider that image processing system 10 comprises that hard disk and the corresponding code 51 of coded key are stored in the situation in this hard disk, if coded document 12 is (promptly in a plurality of image processing systems) decoding in a plurality of places that separate, need the connection between these image processing systems of coordination, and the stores synchronized content, this causes complex system.Yet, in the present embodiment, owing to the corresponding code 51 of coded key is written to attached on the electronic tag on the coded document 12 33, thereby might prevent that locking system becomes complicated, and can use the document protection function with low cost.
In addition, according to this embodiment of the invention,, thereby can prevent to use simple coded key to infer out decoding key because decoding key and coded key generate automatically by image processing system 10.
The present invention can have other variant.
In the above embodiment of the present invention, described all images data that are used to print have been encoded and to the printing image situation of decoding.Yet, the invention is not restricted to this formation, might use following structure, in this structure, as shown in figure 10, by the secret content in the entire document is specified by the application program of main frame HC, 40 of system controllers are to secret content encoding, and write the information of this secret content of expression in electronic tag 33.In decoding schema, read this information, above-mentioned then decode procedure is only implemented at secret content, implements common processing for other guide.
In addition, have a kind of like this structure, wherein, by header (header) and footer (footer) being set to the beginning and the end of little pattern string respectively, not with the information stores of presentation code content in electronic tag 33.
In addition, might have a kind of like this structure, wherein the public keys of asymmetric key cipher system is used as the coded key of the corresponding code 51 of coded key, and the corresponding code 51 of coded key itself is used as public keys, and the private cipher key of asymmetric key cipher system is used as decoding key.
And, in the image processing system that uses two or more coded systems selectively, might have two or more unique data, in this case, in the step S10 of Fig. 9, if store in the electronic tag 33 with two or more unique data in a corresponding unique data, then confirm as coupling.
And, though in the embodiment of the invention described above, described example, also can adopt the structure that data bitmap or corresponding image compression data are encoded to the coded image data of describing with PDL.
And, use the example of electronic tag 33 though in the above-mentioned embodiment of the invention, described as the decoded data tape deck, but also can adopt such structure, as shown in figure 11, the code of the corresponding code 51 of unique code 50 and coded key is converted into aforesaid little pattern, in the header 53 on original copy 12 tops, form pattern image, rather than use electronic tag 33.In this structure,, thereby can reduce operating cost because electronic tag 33 is optional.And, because scanner 32 can replace label reader 34 to use and printing element 20 can replace label register 35 to use, so image processing system 10 needn't comprise label reader 34 and label register 35, therefore, might make image processing system 10 with low relatively cost.
Also may have electronic tag 33 or header and be attached to or be formed into structure on each page of original copy 12.
And, because the display screen on the miniprinter is less relatively, so the type that the setting device among the present invention is not limited to have GUI (graphical user interface) can be that for example comprise can character display and the setting device of the device of the key shelf of symbol.
And, are examples of printer or photocopier though in above-mentioned embodiments of the invention, described image processing system 10, image processing system 10 also can be a facsimile machine etc.
