Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer device for inspecting whether or not the print contents printed on both sides of a print product are appropriate and removing defective print products, and a print product printed by the printer device. The present invention relates to a printed matter processing apparatus that performs proper inspection and removes defective printed matter to create an appropriate sent article.

2. Description of the Related Art A method of recording predetermined information on a medium such as paper in a visually recognizable manner is to record the same information on a large amount of medium at high speed by a printing machine using a printing plate. Also, a method of printing arbitrary data on a relatively small number of media at a low speed by a printer used as a terminal device of a computer is well known.
However, there is also a demand for printing a large amount of variable data, that is, different data for each sheet at high speed, and a high-speed printer device for that purpose has been put into practical use.

Such a printer device for printing variable data at a high speed has a conveying means for conveying a print medium at a high speed, a printing means for recording an image on a sheet conveyed by the conveying means at a high speed, and a sequentially input printing. It is composed of a control unit or the like that appropriately controls data so that it is appropriately printed on paper. As the printing means, for example, a method of printing by an inkjet method with an inkjet head is applied. As such a high-speed printer apparatus for performing printing by the inkjet method, for example, an apparatus for performing printing at a speed of 5 m / sec and 15 or more sheets / second for A4 size printing paper has been put into practical use. More practically, there are many cases where double-sided printing in which printing is performed on both sides of the paper is desired. Therefore, for example, by arranging such high-speed printer devices in series, it is possible to perform double-sided printing at a high speed in a batch. A printing system that can be used is also provided.

An application target for effectively using such a high-speed printer is printing of a document having a large amount of printing and having to print different numbers and contents respectively. For example, shipping documents such as invoices for each customer, stock certificates and various cash vouchers to which different numbers are attached respectively. However, when printing such important documents, it is necessary to completely prevent defects such as overlapping and dropping of print contents, defective printing such as scraping and crushing, and variations in line width and shading. It is not allowed to print in low quality, and accurate data must be printed in high quality.

[0005]

By the way, in such a printer device, particularly in a device that performs double-sided printing, the contents printed on the front and back of one printing sheet are not appropriate, that is, the contents on the front and back. There is a case where defective printing such as misalignment occurs. Possible causes include cue mark and page mark detection errors, and signal processing synchronization deviations, but in any case, printed matter with only one side printed causes data on different pages to be printed on the front and back. If one document is printed, the page configuration cannot be properly performed, for example, when one document is spread over a plurality of pages, and if it is continuous paper, defective printing occurs such that front and back page boundaries are displaced. As for printed matter, this means that data of different customers can be printed on a single sheet of paper, or a sent article in which the customer's data different from the destination is written can be created. There is a problem of creating securities.

Therefore, in order to remove such defective printed matter, there is a demand to inspect each printed matter, but it is not possible to visually inspect in real time a printed matter printed at high speed at a speed of 10 sheets or more per second. Obviously, it is impossible, and even if the individual printed matter is inspected after it is printed, it requires a huge amount of workers and a great amount of time, which is practically impossible. Therefore, such a defective printed matter may be output.

Therefore, it is an object of the present invention to inspect the printed contents of the front and back sides and each page of each printed matter that has undergone double-sided printing, thereby eliminating defective printed matters and providing accurate and high-quality printed matters. It is to provide a highly reliable printer device that can output. Further, another object of the present invention is to provide a delivery product in which a defective print product is appropriately excluded from a print product having delivery destination address information printed by such a printer device, and is properly delivered to the delivery destination. It is to provide a printed matter processing device for generating.

[0008]

In order to solve the above-mentioned problems, immediately after the completion of printing, data indicating the print contents of the front and back surfaces of the printed matter is read, and the appropriateness of the print contents is inspected based on the data. However, if the printing is inappropriate, the printed matter is invalidated.

Therefore, the printer device of the present invention includes a printing means for sequentially performing double-sided printing for each predetermined printing unit on a printing paper and the like, and reading the images printed on both sides, and printing one data on the front and back sides. Print result inspecting means for inspecting whether or not it is appropriate as data to be printed on the printing paper of, and a mark indicating that the printed matter is a defective printed matter for the printed matter determined not to be properly printed. And an inspection result printing means for printing. The printing unit corresponds to, for example, a series of delivery data to be delivered to one destination or a series of print data for forming one printed matter. As for this printing unit, if the medium is printing paper, a plurality of printing papers may constitute one printing unit, or one printing paper may constitute one printing paper.

Preferably, the printer device of the present invention further comprises a printed matter selection means for detecting a printed mark of the printed matter and removing a defective printed matter on which the mark is printed.
Further, specifically, the printer device of the present invention further includes a delivery product forming means and a delivery product inspection means. Then, the printer unit prints the data for each print destination including the delivery data and the destination address information as print data of a predetermined unit, and the inspection result printing unit determines that the printing is not properly performed. The printed matter is printed with a mark that substantially invalidates the destination address information of the printed matter, and the sent matter forming means uses the normal printed matter that has not been removed by the printed matter selecting means to send the destination. A deliverable item that can be delivered is formed based on the address information, and the delivery item inspection means inspects the delivery destination address information of the formed delivery item and inspects whether or not the delivery item is appropriately formed.

Specifically, the print result inspecting means identifies the print unit such as a code of the print unit or destination data from the image of the print data printed on the front and back surfaces of the print medium. Each image of possible data is read, and based on the data, it is checked whether or not the print data on both the front and back sides is appropriate. More specifically, the printing means further prints identification data such as a bar code or an OCR character at a predetermined position on each surface of the print medium to identify a printing unit of print data to be printed on the surface. Then, the print result inspection means inspects whether or not the print data on both front and back sides is appropriate based on the identification data printed on each side of the print medium.

Further, the printed matter processing apparatus of the present invention is a printed matter processing apparatus for processing the output printed matter of the printer device for double-sided printing of the data for each destination, reading the images on both the front and back sides of the printed matter, and sending the same. A print result inspection unit that inspects whether or not the data for the destination is properly printed, and a defective print product for a print product that is determined not to be properly printed on the front and back of the print product as a result of the inspection. It has an inspection result printing means for printing a mark indicating that, and a printed matter selection means for removing a defective printed matter on which the mark is printed.

The inspection section 500 includes a print image storage section 24.
0 based on the print image data stored in the inspection image storage unit 460 and the inspection image data read from the printed matter stored in the inspection image storage unit 460, the control unit determines the determination result. Output to 600.
The structure of the inspection unit 500 will be described with reference to FIG. The inspection unit 500 includes a first address counter 501,
A second address counter 502, a first compressor 503,
It has a second compressor 504, a matching circuit 505, an error number counter 506, a format information storage unit 507, and a CPU 508.

The first address counter 501 is a counter that controls the address of the print image data stored in the print image storage unit 240 that is read out to the inspection unit 500. In addition, the second address counter 50
2 is an inspection image storage unit 46 to be read out to the inspection unit 500.
It is a counter that controls the address of the inspection image data stored in 0. The image data of the addresses designated by these address counters 501 and 502 is read from the print image storage unit 240 and the inspection image storage unit 460 and input to the inspection unit 500. Note that these address counters 501, 50
2 is controlled by signals such as initial value setting and count up / down input from the CPU 508.

First compressor 503 and second compressor 5
Reference numeral 04 compresses the print image data read from the print image storage unit 240 and the inspection image data read from the inspection image storage unit 460 when collating the image data with compressed image data. . This compression can be, for example, 2x2 or 3x3.
The image is divided into pixels, and when the total pixel value of each element is equal to or more than a predetermined value, the corresponding pixel is set to 1, and the original image is compressed to 1/4 or 1/9. Further, when performing collation using the original image data without compression, the first compressor 503 and the second compressor 504 output the input image data as they are. It should be noted that the first compressor 503 and the second compressor 504 are enabled and collation is performed with a compressed image, or the image is collated with the original magnification. The setting of the magnification in the case of performing is input from the outside by a control signal (not shown) via the control unit 600.

The matching circuit 505 includes the first compressor 5
Pixels corresponding to the print image data input from 03 and the inspection image data input from the second compressor 504 are sequentially compared and collated, and the result is output to the error number counter 506. In this matching, the difference between the pixel values of the corresponding pixels is obtained, and if the difference is less than a predetermined value, it is determined that both pixels match, and if the difference is more than the predetermined value, it is determined that the pixels are different. . Error counter 506
Accumulates the number of pixels determined as different pixels in the matching result for each pixel performed by the matching circuit 505, and outputs the accumulated result to the CPU 508 as the number of error pixels.

In the CPU 508, the number of error pixels input from the error number counter 506 is compared with a predetermined threshold value THL, and when the number is larger than the threshold value, the original image data stored in the print image storage unit 240 is compared with the original image data. It is determined that the desired printing cannot be performed because the difference between the print image data stored in the inspection image storage unit 460 is large. Further, when matching is completed for all pixels of the image data in a state where the number of error pixels accumulated in the error number counter 506 does not exceed the threshold value THL, it is determined that the print result is normal in matching. .

The format information storage unit 507 stores common format information of print image data input via the control unit 600. This common format information is, for example, data such as a print area of address information, a table position, a mark position, a character position, and other ruled line positions. The information stored in the format information storage unit 507 is read by the CPU 508,
It is used to check the read image data stored in the inspection image storage unit 460.

The CPU 508 collates the print image data and the inspection image data to determine whether or not the printing is properly performed. The CPU 508 first aligns the print image data with the inspection image data, then checks the inspection image data by a structural analysis method described later, and finally, by the first compressor 503 to the error number counter 506. Control the matching process. Also, during these processes, the print image storage unit 240 is always
Also, the first address counter 50 is provided so that desired image data is input from the inspection image storage unit 460.
It controls the first and second address counters 502.

The alignment of the print image data and the inspection image data is a process of detecting the corresponding positions of the image data on the image memories of the print image storage unit 240 and the inspection image storage unit 460. The cue mark is detected based on the pixel on the upper side of the cue mark, or the center of gravity of both black pixels is detected, and the corresponding pixel is determined based on that point.

The check of the inspection image data by the structural analysis method is to extract the structural features of the print image data based on the format information of the print image data stored in the format information storage unit 507. However, it is a process of checking whether or not the print image data is appropriately printed by checking whether or not the inspection image data has the same characteristics. For example, the information of the position of the blank area having a certain area in the print image data is acquired from the information stored in the format information storage unit 507, and the inspection image data stored in the inspection image storage unit 460 corresponds to the information. Check if the location is also a blank area. If the area is properly a blank area, move to the next check, and if black pixels above noise are detected in that area, end the check and control the inspection result indicating that the print result is defective. It is output to the unit 600.

Further, for example, the format information storage unit 5
The ruled line information stored in 07 is acquired, the vertical or horizontal black pixel histogram of the corresponding area is obtained from the inspection image data stored in the inspection image storage unit 460, and whether there is a ruled line at that position. Check whether or not. In addition, when a region where a character is printed is scanned in the direction of the character string, black pixels and white pixels frequently change, so it is possible to detect that a character is printed there. Thus, it is checked whether the character is printed in the area where the character should be printed. In addition, check whether the table is in the proper position on the table and whether the mark is appropriate. At the stage of checking the inspection image data by such a structural analysis method, the control unit 60 immediately gives an inspection result indicating that the print result is defective when a contradiction is detected by the inspection.
It is output to 0 and the subsequent processing is ended.

When all the checks by such a structural analysis method are completed, the CPU 508 controls the first address counter 501, the second address counter 502, and the first compressor 503 to the error number counter 506. Then, the matching process described above is performed. Then, in the CPU 508, the error pixel number input from the error number counter 506 is compared with the threshold value THL, and if the error pixel number becomes larger than the threshold value THL, defective printing is performed,
When the matching is completed without exceeding the threshold value THL, it is determined that the printing is normal. By such an operation, the inspection unit 500
Inspects the print image data stored in the inspection image storage unit 460. The inspection result is output to the control unit 600.

The control section 600 is a control section for controlling each section constituting the printer section 10 to perform a desired operation. Printing conditions and control conditions are input to the control unit 600 from the control unit 50 via the Ethernet I / F in the control unit 600. Based on the input data, the control unit 600 sets operating conditions of the paper conveyance unit 110, the printing unit 200, the image reading unit 400, and the like, conveys the printing paper, prints on the printing paper, and the printed image. Control so that loading of can be done properly in synchronization. Further, the control unit 600 is in the process of printing, and the inspection unit 50
When a signal indicating defective printing is input from 0, the defective printing marking unit 630 is controlled so that the defective printing marking unit 630 performs printing that invalidates the printed matter.

The defective printing marking section 630 is the inspection section 5.
When it is determined in 00 that the print result is a defective print, a mark that invalidates the print content is printed on the print. The defective printing marking portion 630 is
As shown in FIG. 3, it has a fill print head 631 that is a first print head, a defective print mark print head 632 that is a second print head, and a print control unit (not shown). Based on the input signal, the print control unit controls each head to print a desired image at a desired position.

The fill print head 631 is a head for printing a predetermined fill pattern in a predetermined area of the printed matter, whereby the content already printed in the area is made unidentifiable. At first glance, it turns out to be a defective product, so that it can no longer be used as the original product. Specifically, for example, when the printing target is an invoice with an address, the address portion is filled in so that the defectively printed invoice is not actually sent. Further, in the case of printing various securities or cash vouchers, for example, the amount portion and the number portion of the ticket are painted out so that it is apparently unusable. The defective print mark print head 632 prints a predetermined mark on a predetermined area of the defective print by passing it through an inspection device and by a printing operator or the like so that the printed matter can be recognized as a defective print. To do. In the present embodiment, an error code consisting of alphanumeric characters indicating the detected defect type is printed in the blank area at the lower right of the printed matter.

The fill print head 631 and the defective print mark print head 632 have the same configuration and printing method as the head 220 of the printing unit 200, and have a print width of 1 each.
It is an inch inkjet head. Further, these heads can be moved to arbitrary positions in the main scanning direction (direction perpendicular to the paper feeding direction). Therefore, based on the printing paper and the printing format, by moving these heads in advance to the area where the fill pattern or the defective print mark is to be printed, it is possible to print those patterns at any position on the printing paper. it can. In addition,
The exact print position in the print area of each head is controlled by the print control unit in the defective print marking unit 630. In addition, the print control unit detects the position of each printed material based on the output of a cue mark detection sensor (not shown) and an encoder, which are provided in the vicinity of each of the heads, and detects the position of each printed material. Determine the exact print position in the paper feed direction).

The operation unit 610 is an operation terminal for performing relatively simple operations such as setting work conditions and print parameters on the printing unit 200 and notifying the operator of the data notified from the printing unit 200. is there. In the present embodiment, a general-purpose personal computer is RS232C.
It is used by connecting through an interface. Operation unit 6
Further, a log file of the inspection result of the printing state and the like are also output to 10.

The back printing section 12 carries out desired printing on the printing paper 800, which has already been printed on one side by the front printing section 11, on the non-printed side. Since the configuration of the back printing unit 12 is substantially the same as that of the front printing unit 11, description thereof will be omitted.

Regarding the configuration of the double-sided printing inspection unit 13 FIG.
This will be described with reference to FIG. The double-sided printing inspection unit 13 determines whether the print contents printed on the front and back sides of the printing paper 800 by the front printing unit 11 and the back printing unit 12 are appropriately printed as one printed matter, for example, page by page. Check that the contents to be printed on the front and back of the are properly printed. As shown in FIG. 13, the double-sided printing inspection unit 13 includes a front camera 131, a front image memory 132, a front code identifying unit 133, a rear camera 134, and a rear image memory 13.
5, a back code identifying section 136, a collating section 137, and a defective print marking section 138. Further, the double-sided printing inspection unit 13 has a paper conveyance unit (not shown), which conveys the printing paper 800 for which printing has finished and passes through the inside of the double-sided printing inspection unit 13.

Front camera 131 and rear camera 134
Is a printing paper 800 conveyed in the double-sided printing inspection unit 13.
From the front surface and the back surface of each page, the image of the code which is printed at a predetermined position on the surface and which identifies the print content is read. A specific reading position, reading timing, and the like are controlled by a control unit (not shown) in the double-sided printing inspection unit 13. In the present embodiment, the bar code printed on the lower right side of each page is read in the printing units of the front printing unit 11 and the back printing unit 12. As described above, this bar code is data indicating the destination code of the print data and the page of the printed matter for the destination. Front image memory 132 and back image memory 1
Reference numeral 35 is a pattern memory for temporarily storing the image data of the barcode read by the front camera 131 and the rear camera 134.

The front code identifying section 133 and the back code identifying section 136 recognize the bar codes stored in the front image memory 132 and the back image memory 135, and detect their contents. The collating unit 137 is the table code identifying unit 1
The data indicating the printing content on the front surface of the printing paper 800 detected by 33 and the data indicating the printing content on the back surface of the printing paper 800 detected by the back code identifying unit 136 are collated to determine whether or not they are appropriate. judge.

In the data recorded as the bar code, the data of the destination code of the print data is checked whether or not the respective data match. In addition, the data indicating the page of the printed matter is checked whether or not they are printed on the front and back of one sheet and the contradiction is the inner page number. The page number is checked based on a predetermined rule, such as the total number of pages of the printed matter and how to fold the printed matter.
As a result of the inspection, when it is determined that the printing state is not appropriate, a signal to mark the defective printing mark is output to the defective printing marking unit 138.

The defective print marking unit 138 is the collation unit 1.
When it is determined in 37 that the data on the front and back of the printed matter is inappropriate, a mark that invalidates the printed content is printed on the printed matter. The configuration of the defective printing marking unit 138 is almost the same as the configuration of the defective printing marking unit 630 provided on the front printing unit 11 and the back printing unit 12, and the filling print head and the defective printing mark print head make A predetermined position of the defective printed material is filled in and an error code is printed at the predetermined position. The filling position is, for example, the address position that invalidates the printed matter like the defective printing marking portion 630 of the front printing portion 11. The position where the error code is printed is a position slightly shifted so as not to overlap with the error code printed by the front printing unit 11.

The printing paper 8 that has passed through the double-sided printing inspection unit 13
00b is sequentially wound by the roll paper winding unit 15.

Next, the operation of the printer unit 10 will be described with reference to FIG.
4 and FIG. 15. Figure 14 is a pudding
The printing data is printed on the printing paper 800, which is continuous paper, by the printing unit 10.
FIG. 3A is a diagram showing a state in which a printer is printed, and FIG.
The figure which shows the front surface of 800, (B) is the back surface of printing paper 800
FIG. In Figure 15, the mark is on the first page.
It is a figure which shows the printed state. Printing paper 800
For example, it is an invoice for telephone charges, and the billing address is 80.

Specification 803_-1~ 803 _-FiveAnd the advertisement 804 is printed
You. Also, in the upper right of the front and back of the first page of each invoice
804 is printed. According to this cue mark
You can check the position of each invoice separated from the continuous paper.
Can be.

Hereinafter, such a bill will be sent to the printer unit 10.
The operation of the printer unit 10 will be described for the case of printing with. First, the operation unit 610 and the control unit 50 input print contents, print conditions, and the like to the front printing unit 11, back printing unit 12, and double-sided printing inspection unit 13 to initialize each unit. At this time, the type of fill pattern, the filled area, the type of defective print mark, the printing position of the defective print mark, and the like performed by each defective print marking unit are also set.

When the initial setting is completed, the bitmap image data is input to the front printing unit 11 via the interface unit 250, stored in the print image storage unit 240, and then printed on the printing paper 800 by the printing unit 200. . At this time, each page has a billing address 801, billing information 802, and billing details 803 ₋₁ to 80
_3-5 , each print data such as the advertisement 804, and the barcode 806 including the destination code and the page number are collectively printed. The image printed on the printing paper 800 is read by the image reading unit 400 and stored in the inspection image storage unit 460.
The original image data stored in the inspection unit 500
Are compared and collated, and it is determined whether the two images match. If the two images match, it is determined that the printing has been properly performed, and the printed matter is sequentially conveyed as it is.

If a black line 810 as shown in FIG. 15 is generated in the image printed by the printing unit 200 during the sequential execution of the printing process, the image reading unit 400 reads the inspection image. The image stored in the storage unit 460 and the print image storage unit 2
The original image data stored in 40 does not match because of this black line 810. As a result, the inspection unit 500 detects that the print state is bad.

The control unit 600, to which the signal indicating that the printing state is defective is input from the inspection unit 500, immediately fills the defective printing marking unit 630 with a predetermined area of the invoice and the detected defective state. A signal for printing an error code indicating is output. As a result, the fill print head 631 fills the area 821 black so that the contents below cannot be seen. Further, the defective print mark print head 632 of the defective print marking unit 630 records an error code 822 in the lower right area of the printing paper.

Printing paper 800 on which these printings have been performed
Are sequentially conveyed to the back printing unit 12 regardless of whether the printing is appropriate or not. The back printing unit 12 also performs substantially the same processing on the printing paper 800 as the front printing unit 11. That is, the bitmap image data for back side printing is sequentially input, and is printed on the printing paper 800 from the printing unit via the print image storage unit. The printed image is immediately read and collated with the original image data to determine if printing was done properly. If the printing is not performed properly, the error code is printed at the lower right position on the back surface. It should be noted that in the present embodiment, since there is no appropriate item for invalidating the printed matter corresponding to the address on the front side in the printed content on the back side, the back printing section 12 does not fill the defective printed matter. The printing paper 8 that has been processed in this way, and as a result, printed on the front and back
00 is conveyed to the double-sided printing inspection unit 13.

In the double-sided printing inspection section 13, the bar code printed on the right side of both sides of the conveyed printing paper 800 is used as the front camera 131 and the rear camera 134.
To read from both sides simultaneously. Then, the front code identifying section 133 and the back code identifying section 136 recognize the data, and the collating section 137 collates the data. The collating unit 137 first collates the destination codes to determine whether or not they match. Also, the page numbers are collated to check whether the back surface has a value that is three more than the front surface.

As a result of the inspection, when the data printed on both sides of the printing paper 800 are inconsistent, the defective print marking portion 138 fills a predetermined area of the bill and the detected defective state. Is printed. These prints are printed on paper 8
The area to be filled on the surface of No. 00 is the same as the area to be filled when the defective printing is detected in the front printing unit 11, and the position to print the error code is the error code printed by the front printing unit 11. It is a position lined up in.
Therefore, when both the front printing unit 11 and the double-sided printing inspection unit 13 are defectively printed, the area 821 in FIG. 15 is doubly filled. The printing paper 800 that has passed through the double-sided printing inspection unit 13 is sequentially wound by the roll paper winding unit 15.

The results of the inspection of each bill in the front printing unit 11, back printing unit 12 and double-sided printing inspection unit 13 are output to the control unit 50 and managed collectively. In this way, in the printer unit 10, the bill is printed continuously on the continuous paper.

Next, the structure and operation of the enclosing section 20 will be described with reference to FIG. FIG. 16 is a block diagram showing the configuration of the enclosing unit 20. The enclosing unit 20 includes a printed matter supply unit 900, a burster 910, a printed matter selection unit 920,
It has an inserter 930, a delivery inspection unit 940, and a stacker 950. A print sheet 800b printed by the printer unit 10 is set in the print product supply unit 900, and the print products printed on the continuous paper are sequentially enclosed in the enclosing unit 20.
To supply. The printing paper 800b, which is printed by the printer unit 10 and sequentially wound up, is automatically set in the enclosing unit 20 for each roll by an unillustrated automatic transport device. The printed printing paper 800b set in the printed material supply unit 900 is sequentially unwound by a paper conveyance unit (not shown), passes under the camera 921 of the printed material selection unit 920, and is supplied to the burster 910. It

The bar star 910 cuts the printed matter supplied in the form of the printing paper 800b into each printed matter. The burster 910 detects a cue mark printed on the print sheet 800b by a cue mark detection sensor (not shown), and sequentially cuts the print sheet 800b at the cue mark. For example, in the case of the printing paper shown in FIG. 12, cue mark 804 _-1, respectively the printing paper is cut at a point 804 _-2. As a result, the printed matter printed by the printer unit 10 is divided for each bill. The separated printed matter is conveyed in the enclosing unit 20 in the same manner as the cut paper.

The print selection unit 920 distinguishes between prints that are properly printed and prints that are improperly printed, and removes prints that are improperly printed, from the sequentially supplied prints.
Select only prints that are suitable for printing. Printed matter selection unit 92
0 is a camera 921, a pattern memory 922, an identification unit 92.
3, a control unit 924 and a printed matter selection unit 925.
The camera 921 is an image reading device for detecting a defective print mark marked by the defective print marking unit 630 of the printer unit 10. Camera 92
Under the control of the control unit 924, No. 1 fetches the image data of the area where the above-mentioned defective print mark is printed from the printed matter sequentially conveyed in the field of view, and outputs it to the pattern memory 922. The camera 921 has the same configuration as the CCD camera 440 used in the image reading unit 400 of the printer unit 10. The positioning of the area where the defective print mark is printed in the sub-scanning direction (paper feed direction) is performed by a cue mark detection sensor and an encoder (not shown) provided near the camera 921.

The pattern memory 922 stores the image of the defective print mark print area of each print input from the camera 921. The identification unit 923 identifies the content printed in the defective print mark print area of each print stored in the pattern memory 922. In the present embodiment, the same pattern as the pattern of the defective print mark printed by the defective print marking unit 630 of the printer unit 10 is stored in the memory in the discriminating unit 923, and the memory of the identifying unit 923 stores this pattern. The contents of the pattern memory 922 are identified by performing template matching between the pattern and the pattern stored in the pattern memory 922. Therefore, the identification unit 923 detects whether or not the defective print mark is printed on each printed matter and, if printed, the type of the defective print mark, and outputs the detected print mark to the control unit 924.

Based on the identification result from the identification section 923, the control section 924 instructs the printed matter selection section 925 to recognize the printed matter conveyed as a normal printed matter by the inserter 930.
A signal for selecting whether to output as a defective printed matter or to remove the defective printed matter. The control unit 924 also controls the camera 921.
And the output of the identification result to the control unit 50. The printed matter selection unit 925 switches the conveyance path of the printed matter based on the selection signal from the control unit 924, and selects the printed matter that is divided and conveyed in the burster 910 as the printed matter to be directly output to the inserter 930 and the printed matter to be removed. To select. The removed printed matter is stored in the removed paper stacker in the printed matter selecting unit 925.

The inserter 930 appropriately folds the sequentially conveyed printed matter, inserts it into each envelope, and seals it. In the present embodiment, the envelope into which the printed matter is inserted has a window formed of transparent vinyl, and the destination is visible from the outside through the window. Therefore, each printed matter is inserted into the envelope so that the column where the printed matter is printed can be confirmed from this window. In other words, each printed matter has a destination and a management number printed in an area visible through a window provided in the envelope when the envelope is inserted.

The sent item inspection unit 940 uses the inserter 930.
For each envelope conveyed further, it is checked whether or not the printed matter is properly inserted, and which printed matter is properly inserted. The sent item inspection unit 940 performs the above-described inspection by reading the address information and the management number that can be confirmed through the window provided in the envelope. That is, when the management number is read properly through the window, if the management number is properly read, it is determined that the printed matter is properly inserted, and the printed matter is specified based on the management number. If the control number cannot be read, it is determined that the insertion state of the printed matter is not appropriate,
Further, when the area where the management number should be printed is filled, it is determined that the printed matter of defective printing is mixed in the first place.

The sent item inspection section 940 has a camera 941, a pattern memory 942, an identification section 943 and a control section 944. Each of these components has substantially the same function as the corresponding component of the printed matter selection unit 920. Camera 941
Is an image of a predetermined area of the envelope in which the printed matter to be conveyed is enclosed, specifically, an area corresponding to the transparent window of the envelope, including the area in which the control number is printed. Read the image of the area. Camera 92
1 controls the control unit 944 to fetch image data of a desired area from each envelope sequentially transported in the field of view, and outputs the image data to the pattern memory 942. This camera 941 is also the image reading unit 4 of the printer unit 10.
The configuration is the same as that of the CCD camera 440 used in No. 00.
Positioning of the reading area in the sub-scanning direction (paper feed direction) is performed based on signals from an edge detection sensor and an encoder (not shown) provided near the camera 941.

The pattern memory 942 stores the image input from the camera 941. The identification unit 943 identifies the management number from the image stored in the pattern memory 942. In the present embodiment, the same pattern as the pattern of the management number printed in the printer unit 10 is stored in the memory in the identification unit 924, and the stored pattern and the pattern stored in the pattern memory 942 are stored. By matching and, the pattern memory 942
Identify the contents of. Therefore, the identification unit 943 outputs information indicating the management number if it can be identified, and if it cannot be identified, information indicating whether or not the paint pattern is printed in the area.

The control unit 944 outputs the identification result from the identification unit 943 to the control unit 50. It is basically rare for an abnormal printed matter to be found in the sent item inspection unit 940, and the main function is to check a normal control number. Therefore, here, even when an abnormality is found, the handling of the envelope is not particularly changed, and only the information is output to the control unit 50. The control unit 944 also controls the camera 921.

The stacker 950 stores and stores each printed matter that is inserted into the envelope in the enclosing section 20 and is ready to be sent.

Next, the reprint printer section 40 will be described. The reprint printer unit 40 is a printer for reprinting a printed matter that has become defective in the printer unit 10. Therefore, a printer device is used that can reliably print even if the printing speed is somewhat slow. In this embodiment, an electrophotographic laser beam printer using a laser is used. The printed matter printed by the reprint printer section 40 is also put into the enclosing section 20 in the same manner as the printed matter printed by the printer section 10.

Finally, the control unit 50 will be described. The control unit 50 is a host computer that controls the entire printing system 1. First, the control unit 50 is externally input with information indicating the print content to be printed on each printed matter, generates a print image printable in the printer unit 10 based on the information, and outputs the print image to the printer unit 10. Further, the control unit 50 manages the print state, the inspection result, and the like of the printed matter inspected by the front printing unit 11, the back printing unit 12, the double-sided printing inspection unit 13, and the enclosing device 20 of the printer device 10. That is, inspection and management are performed so that a properly printed printed matter is properly inserted into an envelope and a sent article is created without duplication and omission.

For this purpose, the control unit 50 always stores a list of printed materials to be printed with the management numbers of the printed materials to be printed, and manages each printed material. Then, when printing is performed by the front printing unit 11 and the back printing unit 12, the inspection result of each printing is input to the control unit 50, and whether the printing state is appropriate or not, and when it is not appropriate, the error A code or the like is stored in association with the management number. Further, the result of the consistency check of the print contents on both sides of the printed matter in the double-sided print inspection unit 13 is also input to the control unit 50 and stored for each management number.

Further, when insertion into the envelope is started in the enclosing unit 20, two check results performed by the printed matter selecting unit 920 and the sent item inspecting unit 940 of the enclosing unit 20 are input to the control unit 50. From the printed matter selection unit 920,
Information indicating the detection of a defective print mark for each print target and whether the print is removed or sent to a subsequent process based on the detection is input. The control unit 50 records the information in association with the management number and compares it with the inspection result already input from the printer unit 10,
It is confirmed that the properly printed printed matter is surely sent to the inserter 930, and the defective printed matter is surely removed. When these two inspection results are inconsistent with each other or when the inconsistencies are continuous, a cause investigation and printing stop processing are performed.

From the sent product inspection unit 940, the inspection result in the state where the final printed matter is inserted in the envelope is input, and normally, as the inspection result, the processing is properly finished. Since the control number of the printed matter is entered,
The control unit 50 terminates the processing of the printed matter of that management number, and substantially removes it from the management target. But,
When the detection of the defective printed matter is input from the sent product inspection unit 940, the presence of the defective printed matter is notified and the stacker 950 outputs information that allows the defective printed matter to be taken out.

When a series of printing such as a printing process for one roll of paper is completed, the control unit 50 still remains as a management target, that is, the final print is not produced due to defective printing. Extract printed material. Then, the control unit 50 causes the reprint printer unit 40 to reprint the printed matter. The control unit 50
The printed matter obtained as a result of the reprinting is put into the enclosing section 20 to be subjected to the encapsulation processing, and a signal indicating that the processing has been appropriately completed is input to the reprinted matter from the sent item inspection section 940, and management is performed. When the target printed matter is exhausted, the series of processes is ended.

To summarize the operation of the printing system 1 described above, first, in the front printing unit 11 and the back printing unit 12 of the printer unit 10, different data for each printed matter are sequentially printed at high speed, and the printing is performed. The image is taken with a camera and the print status is checked. When defective printing is found as a result of the printing, a mark is printed on the printed matter. This mark is classified into two types: a mark indicating a normal defective print and a mark that fills an important item of the printed matter. Further, the printed matter on which the double-sided printing is completed is put into the double-sided printing inspection section 13, and the consistency of the printed contents on the front and back sides is inspected for each printed matter (each page). A mark indicating defective printing similar to the above is printed.

When the printing is completed by these processes, the printed matter is set in the enclosing section 20, where the continuous paper is sequentially cut and separated into one printed matter. Then, the defective print mark printed by the printer unit 10 is checked, and the printed matter on which the mark is printed is immediately discarded. The printed matter without the mark printed is enclosed in an envelope so that it can be sent, and at that time, a final check is performed. That is, it is checked whether the address and management number of the printed matter can be seen in the transparent window of the envelope. During these processes, the control unit 5
The inspection results at each stage are sequentially input to 0, and they are associated with each other to ensure that the defective printed matter is discarded.
It is always checked that a normal printed matter is properly inserted into the envelope and output, and that there is no abnormal state or inconsistency during the processing. Further, the printed matter discarded as the defective printed matter is printed in the reprint printer unit 40, and is inserted into the envelope again in the enclosing unit 20.

As described above, in the printing system 1 of the present embodiment, a large amount of printed matter can be printed at high speed. The printed matter is automatically inserted into the envelope and is ready to be sent. Therefore, when there is a large amount of printed matter such as a bill that needs to print different data, the printed matter can be efficiently created and shipped. At that time, the printing condition of the printed matter and the consistency of the data on the front and back of each page are checked immediately after printing, and the state of the printed matter at all times (whether it is discarded or is it proceeding to the subsequent process as a valid printed matter)
Is known and has undergone a final check after being inserted into the envelope. Therefore, it is possible to almost completely prevent erroneous processing such as poor printing, missing or misaligned pages, missing or overlapping printed matter, and even sending printed matter with different contents. .

The present invention is not limited to this embodiment, and various modifications can be made. For example, the configuration of the printer unit 10 is not limited to the configuration shown in FIGS. 1 and 2. In the present embodiment, the front side and the back side of the printed matter are printed by the front printing section 11 and the back printing section 12, which are separate printing sections, but the front side is first printed by one printing section. Then
Then, the back side may be printed.

Further, the method of checking the consistency of the printed contents on the front and back sides in the double-sided printing inspection unit 13 is not limited to the method of comparing and collating the bar code indicating the printed contents as in the present embodiment, and any method can be used. Good. For example, as shown in FIG. 17, when the data for identifying the destination such as the telephone number 807 is printed in the print image for each page, the portion of the data is read and the identification result is obtained. May be collated.

The defective print marking portion 630 does not have to include both the fill print head 631 and the defective print mark print head 632, and may be configured to have only one of them.
Further, the mark indicating the defective print printed by the defective print mark print head 632 is not limited to the error code as shown in FIG. For example, in FIG.
It is possible to clearly indicate that the printed matter is a defective printed matter by an arbitrary figure as shown in FIG.
As shown in FIG. 8 (B), it may be possible to mark whether or not the explanatory note is valid with respect to the explanatory note clearly indicating that the printed matter is not effective. Alternatively, a barcode or the like may be used.

The print medium is shown in this embodiment.
It is not limited to continuous paper such as
Yes. In that case, the roll paper supply unit 1 of the paper transport unit 110
10 _-1As a hopper unit to supply cut paper

For this, an edge detector is provided for positioning in the sub-scanning direction.
What should I do? Of course, the printing medium is paper
The print medium may be an external material, and the print medium
The printing mechanism is optional depending on the printing medium.
It may be configured.

Further, the filling print head 631 and the defective print mark print head 632 of the defective print marking portion 630 are not limited to the ink jet type heads, and may be any type of heads. Further, the printer unit 10 is not limited to a printer device that prints in black and white two colors, but is also applicable to a printer device that performs multi-value printing, multi-color printing, full-color printing, or the like. In addition, the detailed configurations of the printer unit 10 and the enclosing unit 20, the inspection method in each inspection unit, and the like are not limited to the present embodiment, and may have any configurations.

[0090]
