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 print contents performed on both sides of a printed material are appropriate and for removing a defective printed material, and for a printed material printed by the printer device. The present invention relates to a printed matter processing apparatus that performs an appropriate inspection and removes a defective printed matter to create an appropriate sent matter.

2. Description of the Related Art As a method of recording predetermined information on a medium such as paper so as to be visually recognizable, a method of recording the same information on a large amount of medium at high speed by a printing machine using a printing plate is known. 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 or the like is well known.
However, there is also a demand for printing a large amount of variable data, that is, different data, for example, one by one at a high speed, and high-speed printers have been put to practical use.

[0003] Such a printer apparatus for printing variable data at a high speed includes a conveying means for conveying a print medium at a high speed, a printing means for recording an image at high speed on a sheet conveyed by the conveying means, and a printing means for sequentially inputting. It is composed of control means for appropriately controlling data so that the data is appropriately printed on paper. As the printing means, for example, a method of performing printing by an inkjet method using an inkjet head is applied. As such a high-speed printer device that performs printing by the ink jet method, for example, a device that performs printing at a speed of 15 sheets per second or more for A4 size printing paper at 5 m / s has been put to practical use. Further, practically, it is often desired to perform double-sided printing in which printing is performed on both sides of a sheet. For example, such a high-speed printer is arranged in series to perform double-sided printing at a high speed. There is also provided a printing system capable of performing the printing.

[0004] An application to which such a high-speed printer device is effectively used is printing of a document in which a large amount of printing is required and different numbers and contents must be printed respectively. For example, shipping documents for each customer such as invoices, stock certificates and various cash vouchers each having a different number, and the like. However, when printing such important documents, it is necessary to completely prevent defects such as duplication or omission of print contents, as well as defective printing such as blurring or crushing, line width and shading variation. However, low-quality printing is not allowed, and accurate data must be printed with high quality.

[0005]

By the way, in such a printer device, particularly in a device that performs double-sided printing, the content printed on the front and back of one print sheet is not appropriate, that is, the content of the front and back is In some cases, defective printing in which the image is shifted may occur. Possible causes include misdetection of cue marks and page marks, and out-of-synchronization in signal processing.In any case, printed matter with only one side printed may occur. When a single document is printed on a plurality of pages, the page configuration cannot be properly performed. Further, in the case of continuous paper, defective printing such as a shift between front and back page boundaries occurs. This means that, in terms of printed materials, data of different customers can be printed on one sheet of paper, a sentence containing data of customers different from the destination can be created, and cash vouchers with different front and back numbers can be used. There is a problem of creating securities and the like.

In order to remove such defective prints, there is a demand to inspect individual prints. However, it is not possible to visually inspect prints printed at a high speed of 10 sheets or more per second in real time. Naturally, it is impossible, and even if each printed matter is inspected after being printed, it requires a huge number of workers and a huge amount of time, which is practically impossible. Therefore, there is a possibility that such a defective printed matter is output.

Accordingly, an object of the present invention is to inspect the printed contents of each side and each page of each printed material subjected to double-sided printing, thereby eliminating defective printed materials and producing accurate and high quality printed materials. It is an object of the present invention to provide a highly reliable printer capable of outputting. Further, another object of the present invention is to appropriately remove defective printed materials from printed matter having destination address information printed by such a printer device, and to reduce a printed matter that is appropriately sent to the destination. An object of the present invention is to provide a print processing apparatus that generates the print data.

[0008]

In order to solve the above-mentioned problems, data indicating the print contents of the front and back sides of a printed matter are read immediately after printing, and the appropriateness of the print contents and the front and back sides are determined based on the data. The printed contents on both sides were checked for consistency, and if the printing was inappropriate, the printed matter was invalidated.

0, based on the print image data stored in the storage unit 460 and the inspection image data read from the printed matter stored in the inspection image storage unit 460, and determines whether the printing state is appropriate. Output to 600.
The configuration 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 for controlling an address of print image data stored in the print image storage unit 240 to be read out to the inspection unit 500. Also, the second address counter 50
2 is an inspection image storage unit 46 to be read out to the inspection unit 500
This is a counter for controlling the address of the inspection image data stored in 0. The image data at the addresses designated by the address counters 501 and 502 are read out from the print image storage unit 240 and the inspection image storage unit 460 and input to the inspection unit 500. 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
A step 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 the collation of the image data is performed using the compressed image data. . This compression is, for example, 2 × 2 or 3 × 3
The original image is compressed to 1/4 or 1/9 by dividing the image into pixels of the original image, and when the total pixel value of each element is equal to or larger than a predetermined value, setting the corresponding pixel to 1. When collation is performed using original image data without performing compression, the first compressor 503 and the second compressor 504 each output the input image data as it is. It should be noted that the first compressor 503 and the second compressor 504 are enabled and the mode is set so that the comparison is performed with the compressed image or the image is compared with the original magnification, and the comparison is performed with the compressed image. The setting of the magnification in the case of performing is performed by a control signal (not shown) via the control unit 600 from the outside.

The matching circuit 505 includes the first compressor 5
Corresponding pixels of the print image data input from the input unit 03 and the inspection image data input from the second compressor 504 are sequentially compared and collated, and the result is output to an error counter 506. In this comparison, the difference between the pixel values of the corresponding pixels is determined. If the difference is less than a predetermined value, the pixels are determined to be the same, and if the difference is equal to or greater than the predetermined value, the pixels are determined to be different. . Error counter 506
Accumulates the number of pixels determined as different pixels in the result of the matching performed for each pixel by the matching circuit 505, and outputs the accumulated result to the CPU 508 as the number of error pixels.

The CPU 508 compares the number of error pixels input from the error number counter 506 with a predetermined threshold value THL. When the number of error pixels exceeds the threshold value, the original image data stored in the print image storage section 240 is compared with the threshold value THL. It is determined that there is a large difference between the print image data stored in the inspection image storage unit 460 and the desired printing cannot be performed. When matching has been 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 in the matching that the printing result is normal. .

The format information storage unit 507 stores common format information of print image data input via the control unit 600. The 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. Information stored in the format information storage unit 507 is read by the CPU 508,
It is used for checking the read image data stored in the inspection image storage unit 460.

The CPU 508 compares the print image data with the inspection image data to determine whether the printing has been 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, checks the first compressor 503 to the error number counter 506. Controls the matching process. Also, during these processes, the print image storage unit 240
And the first address counter 50 so that desired image data is input from the inspection image storage unit 460.
The first and second address counters 502 are controlled.

The alignment between the print image data and the inspection image data is processing for detecting the corresponding position of the image data on each image memory of the print image storage unit 240 and the inspection image storage unit 460. For example, processing is performed based on the pixel on the upper side where the cue mark is detected, or the center of gravity of both black pixels is detected, and the corresponding pixel is determined based on the point.

The check of the inspection image data by the structural analysis method means that the structural features of the print image data are extracted based on the format information of the print image data stored in the format information storage unit 507. Then, by checking whether or not the inspection image data has the same characteristics, it is a process of checking whether or not the print image data is appropriately printed. For example, information on the position of a blank area having a certain area in the print image data is obtained from the information stored in the format information storage unit 507, and corresponding to the inspection image data stored in the inspection image storage unit 460. Check if the location is also a blank area. If the area is properly a blank area, proceed to the next check, and if a black pixel with noise or more is detected from that area, end the check and control the inspection result that the printing result is bad Output to the unit 600.

For example, the format information storage unit 5
07 is obtained, a vertical or horizontal black pixel histogram of a corresponding area is obtained from the inspection image data stored in the inspection image storage unit 460, and whether a ruled line exists at that position. Checking whether or not. In addition, when a region where characters are printed is scanned in the character string direction, black and white pixels frequently change, so that it is possible to detect that characters are printed there. To check whether the character is printed in the area where the character should be printed. In addition, a check is made to see if the table is properly located where the table should be, and if the mark is properly located. At the stage of checking the inspection image data by these structural analysis methods, the control unit 60 immediately outputs the inspection result indicating that the printing result is defective when inconsistency is detected by the inspection.
0 is output, and the subsequent processing ends.

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, the CPU 508 compares the number of error pixels input from the error number counter 506 with the threshold value THL.
If 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 from the control unit 50 to the control unit 600 via the Ethernet I / F in the control unit 600. The control unit 600 sets the operating conditions of the paper transport unit 110, the printing unit 200, the image reading unit 400, and the like based on the input data, transports the print paper, prints on the print paper, and prints the printed image. Is controlled so that it can be read properly in synchronization. Further, the control unit 600 is in the printing operation,
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 connected to the inspection section 5
If it is determined that the print result is a defective print in 00, a mark is printed on the print to invalidate the print content. The defective printing marking section 630 includes:
As shown in FIG. 3, the control unit 600 includes a print head 631 for filling, which is a first print head, a defective print mark print head 632, which 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 print head for filling 631 is a head for printing a predetermined fill pattern in a predetermined area of a printed material, and thereby, the contents already printed in the area are filled to make it indistinguishable. , At first glance it turns out to be defective, so that the print can no longer be used as the original print. Specifically, for example, when the printing target is an invoice with an address, the address portion is painted out so that the invoice with the defective printing is not actually sent. Further, when the printing target is various kinds of securities or cash vouchers, for example, the money portion or the number portion of the voucher is painted out so as to be apparently unusable. The defective print mark print head 632 prints a predetermined mark on a predetermined area of the defective printed material by passing the inspection device, and when a printing operator or the like sees the printed material as a defective printed material. I do. In the present embodiment, an error code consisting of alphanumeric characters indicating the type of detected defect is printed in a blank area at the lower right of the printed matter.

The filling print head 631 and the defective print mark print head 632 have the same configuration and printing system as the head 220 of the printing unit 200, and each has a printing width of 1 unit.
Inch inkjet head. Further, these heads can be moved to an arbitrary position in the main scanning direction (a direction perpendicular to the sheet feeding direction). Therefore, based on the paper to be printed and the print 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 an arbitrary position on the print paper. it can. In addition,
The exact printing position in the printing area of each head is controlled by the printing control unit in the defective printing marking unit 630. The print control unit detects the position of each printed material one by one based on an output of a cue mark detection sensor (not shown) and an encoder (not shown) provided in the vicinity of each of the heads. Determine the correct printing position (paper feed direction).

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

The back printing unit 12 performs desired printing on the printing paper 800 on which printing has already been performed on one side by the front printing unit 11, on the surface on which printing has not been performed. The configuration of the back printing unit 12 is substantially the same as that of the front printing unit 11, and a description thereof will be omitted.

FIG. 13 shows the configuration of the double-sided printing inspection unit 13.
This will be described with reference to FIG. The double-sided printing inspection unit 13 checks whether the print content printed on the front and back sides of the printing paper 800 by the front printing unit 11 and the back printing unit 12 is appropriately printed as one printed matter, for example, Check that the contents to be printed on the front and back 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 identification unit 133, a back camera 134, and a back image memory 13.
5, a back code identification unit 136, a collation unit 137, and a defective print marking unit 138. Further, the double-sided printing inspection unit 13 has a sheet transport unit (not shown), and conveys the printing paper 800 on which printing has been completed, and passes the inside of the double-sided printing inspection unit 13.

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

The front code identification section 133 and the back code identification section 136 recognize the barcodes stored in the front image memory 132 and the back image memory 135 and detect the contents. The collation unit 137 includes the table code identification unit 1
The data indicating the print content on the front surface of the printing paper 800 detected at 33 is compared with the data indicating the print content on the back surface of the printing paper 800 detected by the back code identification unit 136, and whether or not they are appropriate is determined. judge.

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

The defective print marking section 138 is provided by the collation section 1
If it is determined in step 37 that the data on the front and back of the printed matter is inappropriate, a mark that invalidates the print content is printed on the printed matter. The configuration of the defective print marking section 138 is almost the same as the configuration of the defective print marking section 630 provided in the front print section 11 and the back print section 12, and includes a solid print head and a defective print mark print head. A predetermined position of the defective print is painted out, and an error code is printed at the predetermined position. The fill-in position is, for example, a position of an address where the printed matter is invalidated similarly to the defective print marking unit 630 of the front print unit 11. The position where the error code is printed is a position shifted slightly so as not to overlap with the error code printed by the table printing unit 11.

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

Next, the operation of the printer unit 10 will be described with reference to FIG.
4 and FIG. Figure 14 shows the pudding

FIG. 7A is a diagram illustrating a state in which the data is printed, and FIG.
FIG. 8B illustrates a front surface of the printing paper 800, and FIG.
FIG. FIG. 15 shows the mark on the first page.
FIG. 7 is a diagram illustrating a printed state. The printing paper 800 is
For example, it is a bill such as telephone charges, and the billing address 80
1. Billing information 802, billing content over 5 pages
Details 803 of_-1~ 803 _-FiveAnd the advertisement 804 is printed
You. Also, on the first page of each bill,
Mark 804 is printed. This cue mark
To find the break position of each invoice from the continuous paper.
Can be.

Hereinafter, such an invoice is sent to the printer unit 10.
The operation of the printer unit 10 will be described for the case of printing with. First, printing contents, printing conditions, and the like are input from the operation unit 610 and the control unit 50 to the front printing unit 11, the back printing unit 12, and the double-sided printing inspection unit 13, and each unit is initialized. At this time, the type of fill pattern, the fill area, the type of defective print mark, the print 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 table 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 includes a billing address 801, billing information 802, and billing details 803 _-1 to 803-80.
3 _-5 , print data such as advertisement 804, and a bar code 806 including a destination code and a page number thereof are printed collectively. 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, and the print image storage unit 240
The original image data stored in the inspection unit 500
Are compared and it is determined whether or not both images match. If the two images match, it is determined that printing has been properly performed, and the printed matter is sequentially conveyed as it is.

Assuming that 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 such a printing process, the image reading unit 400 reads out the inspection image. The image stored in the storage unit 460 and the print image storage unit 2
Due to this black line 810, the original image data stored in 40 does not match. As a result, the inspection unit 500 detects that the printing state is defective.

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

The printing paper 800 on which these printings have been performed
Are sequentially conveyed to the back printing unit 12 irrespective of printing suitability. In the back printing unit 12, substantially the same processing as that in the front printing unit 11 is performed on the printing paper 800. That is, bitmap image data for backside printing is sequentially input, and is printed on printing paper 800 by the printing unit via the printing image storage unit. The printed image is immediately read and compared with the original image data to determine whether the printing has been properly performed. If printing has not been performed properly, an error code is printed at the lower right position on the back surface. 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 unit 12 does not paint the defective printed matter. The printing paper 8 that has been processed in this way and as a result has been printed on the front and back sides
00 is conveyed to the double-sided printing inspection unit 13.

In the double-sided printing inspection section 13, the barcodes printed on the right side of both sides of the printing paper 800 conveyed are scanned by the front camera 131 and the rear camera 134.
To read from both sides simultaneously. Then, the data is recognized by the front code identification unit 133 and the back code identification unit 136, and collation is performed by the collation unit 137. The collation unit 137 first collates the destination codes and determines whether they match. In addition, the page numbers are collated, and it is checked whether or not the back side has a value larger by three than the front side.

As a result of the inspection, if there is inconsistency in the data printed on both sides of the printing paper 800, the defective print marking unit 138 fills a predetermined area of the bill with the detected defective state. Is printed. These printings are performed on printing paper 8
The area to be painted and painted over is the same as the area to be painted out when defective printing is detected in the front printing unit 11, and the error code printing position is the error code printed by the front printing unit 11. It is a position aligned with.
Therefore, when both the front printing unit 11 and the double-sided printing inspection unit 13 perform defective printing, the area 821 in FIG. 15 is double-painted. 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 sequentially.

The inspection results for each bill in the front printing unit 11, the back printing unit 12, and the 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 and continuously on the continuous paper.

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

The bar star 910 cuts the printed material supplied in the form of the printing paper 800b for each printed material. The burster 910 detects a cue mark printed on the printing paper 800b by a cue mark detection sensor (not shown), and sequentially cuts the printing paper 800b at the position of 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 cut printed material is conveyed in the enclosing section 20 in the same manner as cut paper.

The printed material selection unit 920 distinguishes between printed materials that have been properly printed and printed materials that are inappropriately printed from sequentially supplied printed materials, and removes printed materials that are inappropriately printed.
Select only prints that are appropriate for printing. Print sorting section 92
0 is the camera 921, the pattern memory 922, the identification unit 92
3. It has a control unit 924 and a printed material sorting unit 925.
The camera 921 is an image reading device for detecting a defective print mark marked in the defective print marking unit 630 of the printer unit 10. Camera 92
1 is controlled by the control unit 924 to capture image data of an area where the above-described defective print mark is printed from a printed material sequentially conveyed in the field of view, and output the image data to the pattern memory 922. This 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 printing area of each printed material input from the camera 921. The identification unit 923 identifies the content printed in the defective print mark printing area of each printed material stored in the pattern memory 922. In the present embodiment, the same pattern as the pattern of the defective print mark printed in the defective print marking unit 630 of the printer unit 10 is stored in the memory in the identification unit 923. 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 a defective print mark is printed on each printed material, and if so, the type of the print mark, and outputs it to the control unit 924.

Based on the identification result from the identification unit 923, the control unit 924 sends the conveyed prints as normal prints to the inserter 930 to the print selection unit 925.
Or a signal for selecting whether the output is to be removed as a defective print. Also, the control unit 924 controls the camera 921
And outputs the identification result to the control unit 50. The printed material selection unit 925 switches the transport path of the printed material based on the selection signal from the control unit 924, and outputs the printed material that is divided and transported by the bar star 910 to the inserter 930 as it is and the printed material to be removed. To be sorted out. The removed printed matter is stored in a removed paper stacker in the printed matter sorting unit 925.

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

The delivery inspection unit 940 includes an inserter 930.
It is checked whether or not the printed matter is properly inserted into each of the envelopes to be transported, and which printed matter is properly inserted. The delivery inspection unit 940 performs the inspection by reading the address information and the control number that can be confirmed from the window through the window provided on the envelope. In other words, when the management number is properly read when trying to read the management number through the window, it is assumed 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 inserted state of the printed matter is not appropriate,
If the area where the management number is to be printed is filled, it is determined that a defective printed matter is mingled in the first place.

The delivery inspection unit 940 includes a camera 941, a pattern memory 942, an identification unit 943, and a control unit 944. These components have substantially the same functions as the corresponding components of the printed material sorting 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 an area where the control number is printed. Read the image of the area. Camera 92
1 is controlled by the control unit 944 to fetch image data of a desired area from each envelope sequentially conveyed in the field of view and output it to the pattern memory 942. The camera 941 is also connected to the image reading unit 4 of the printer unit 10.
The configuration is the same as that of the CCD camera 440 used in 00.
The positioning of the reading area in the sub-scanning direction (paper feed direction) is performed based on signals from an edge detection sensor (not shown) and an encoder (not shown) provided near the camera 941.

The pattern memory 942 stores an 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 management number pattern printed by 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. And the pattern memory 942
Identify the contents of Therefore, from the identification unit 943, if the management number can be identified, the number is output. If the management number cannot be identified, information indicating whether or not a fill pattern is printed in the area is output.

Control unit 944 outputs the identification result from identification unit 943 to control unit 50. It is basically rare that an abnormal printed matter is found in the sentence inspection unit 940, and the main function is to check a normal management 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 accumulates and stores each printed matter inserted into an envelope in the enclosing section 20 and made ready for sending.

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 that can surely perform printing even if the printing speed is somewhat slow is used. In this embodiment mode, an electrophotographic laser beam printer using a laser is used. The printed matter printed by the reprint printer unit 40 is also put into the enclosing unit 20 in the same manner as the printed matter printed by the printer unit 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 receives information indicating the print content to be printed on each printed material from outside, generates a print image printable by 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 printing state / inspection result of the printed material 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 matter is appropriately inserted into an envelope, and a sent matter is created without duplication or omission.

For this purpose, the control unit 50 always stores a list of the prints to be printed under the management number of the prints to be printed and manages each print. 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 if the printing state is appropriate or inappropriate, and if the printing state is inappropriate, an error A code or the like is stored in association with the management number. Further, the result of the consistency inspection of the printed contents of both sides of the printed material in the double-sided printing inspection unit 13 is also input to the control unit 50 and stored for each management number.

Further, when the insertion into the envelope in the enclosing section 20 is started, two check results performed by the printed material selecting section 920 and the sent matter inspection section 940 of the enclosing section 20 are input to the control section 50. From the printed matter sorting unit 920,
For each print object, information indicating whether a defective print mark has been detected and whether the print has been removed or sent to a subsequent process based on the detection is input. In the control unit 50, the information is recorded in association with the management number, and is compared with the inspection result already input from the printer unit 10,
Appropriately printed matter is surely sent to the inserter 930, and it is confirmed that the defective printed matter is surely removed. When the two inspection results are different from each other or when the differences are continuous, processing such as cause investigation and printing stop is performed.

The inspection result in the state where the individual printed materials are inserted into the envelope, which is the final purpose, is input from the sent material inspection unit 940. Normally, the inspection result indicates that the processing is properly completed. Since the management number of the printed matter is entered,
The control unit 50 terminates the process for the printed matter of the management number and substantially removes the printed matter from the management target. But,
When the detection of a defective print is input from the transmission inspection unit 940, the presence of the defective print is notified, and information is output from the stacker 950 so that the defective print can 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, is removed by defective printing or the like, and a final printed matter is not generated. Extract printed matter. Then, the control unit 50 causes the reprint printer unit 40 to reprint those prints. The control unit 50
The printed matter resulting from the reprinting is put into the enclosing section 20 to perform the enclosing process, and a signal indicating that the reprinted matter has been properly processed is input from the sent matter inspection section 940, and the management is performed. A series of processes is ended when the target printed matter is exhausted.

To summarize the operation of the printing system 1 described above, first, the front printing unit 11 and the back printing unit 12 of the printer unit 10 sequentially print different data for each printed material at high speed, and print the data. The photographed image is photographed by the camera and the printing state is checked. As a result of the printing, if a defective print is found, a mark is printed on the printed matter. As this mark, two types of marks are performed: a mark indicating normal defective printing and a mark that fills important items of the printed matter. Further, the printed material on which double-sided printing has been completed is input to the double-sided printing inspection unit 13, where the consistency of the printed contents on the front and back sides is checked for each printed material (each page). A mark indicating defective printing similar to the above is printed.

When 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 individual printed matters. Then, the printer unit 10 checks for a defective print mark printed, and the printed matter on which the mark is printed is immediately discarded. The printed matter without the mark is enclosed in an envelope to be ready for sending, and at that time, undergoes a final check. That is, it is checked whether the address and control number of the printed matter are visible on the transparent window of the envelope. During these processes, the control unit 5
0, the inspection results at each stage are sequentially input and associated with them, and the defective printed matter is surely discarded;
It is always checked that the 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 a defective printed matter is printed in the reprint printer unit 40 and inserted again into the envelope 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 a high speed. These prints are automatically inserted into the envelope and made ready for sending. Therefore, when there are a large number of printed materials, such as bills, for which different data must be printed, the printed materials can be efficiently created and sent. At that time, the printing condition of the printed material and the consistency of the data on the front and back of each page are checked immediately after printing, and the condition of the printed material (whether discarded or advanced to a later process as a valid printed material)
Has been confirmed, and has undergone a final check after being inserted into the envelope. Therefore, it is possible to almost completely prevent erroneous processing such as a poor printing state, a missing or shifted page, a missing or duplicated printed matter, and a transmission of a printed matter having a different content. .

The present invention is not limited to the present embodiment, and various modifications are possible. For example, the configuration of the printer unit 10 is not limited to the configuration shown in FIGS. In the present embodiment, printing is performed on the front side and the back side of the printed material by the front printing unit 11 and the back printing unit 12, which are separate printing units, respectively. And
Next, a configuration in which the back surface is printed may be adopted.

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 barcodes indicating the printed contents as in the present embodiment, but may be any method. Good. For example, as shown in FIG. 17, when data that can specify the destination such as a telephone number 807 is printed in the print image of each page, the data part is read, and the identification result is obtained. May be collated.

The defective printing marking section 630 does not have to include both the printing head 631 for filling and the printing head 632 for the defective printing mark, and may have a configuration having only one of them.
In addition, the mark indicating the defective print to be printed by the defective print mark print head 632 is not limited to the error code shown in FIG. For example, FIG.
As shown in FIG. 1A, an arbitrary figure may clearly indicate that the printed matter is a defective printed matter, or FIG.
As shown in FIG. 8 (B), it may be possible to mark whether or not the explanation is valid for the explanation which clearly indicates that the printed matter has no effect. In addition, a barcode or the like may be used.

The medium to be printed is shown in this embodiment.
It is not limited to continuous paper such as
No. At that time, the roll paper supply unit 1 of the paper transport unit 110
10 _-1As a hopper unit to supply cut paper
And the roll paper supply unit 110_-1In each part of
An edge detector for positioning in the sub-scanning direction.
What should I do? Of course, the medium to be printed
It may be a print medium of an external material,
Handling mechanism etc. according to the printing medium
It may be configured.

Further, the print head 631 for filling and the print head 632 for the defective print mark of the defective print marking section 630 are not limited to the ink jet type head, but may be any type of head. Further, the printer unit 10 is not limited to a printer device that performs printing in two black and white colors, but is also applicable to a printer device that performs multi-value printing, multi-color printing, or full-color printing. 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 configuration.

[0090]
