Abstract

PROBLEM TO BE SOLVED: To remove imperfect printed matter by scrutinizing the printed results when printing large quantities of individually different print contents at a high speed. SOLUTION: Printed matter is printed at a high speed by a printer part 10, then its printed state is checked and imperfect printed matter is marked. The marking method is to print a character, a character string, a figure or a bar code on the blank space of the printed matter so that causes for an error or the imperfectness of the printed matter can be recognized or the smear the important contents of the printed matter so that it is substantially nullified, and these two alternatives are combined. The printed matter coming out of a printer has its mark checked by a sealing part 20, and the imperfect printed matter is immediately discarded. Normal printed matter is sealed into an envelope and is finally checked to determine whether the sealed printed matter is properly viewed through the transparent window of the envelope. The discarded imperfect printed matter is reprinted by an almost error-free reprinting part 40.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer apparatus capable of inspecting printed matter and removing defective printed matter, and to such printed matter printed on the printer and performing such inspection and removal of defective printed matter. The present invention relates to a printed matter processing apparatus that creates an appropriate delivery.

[0002]

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.

Further, as one of the objects to which such a high speed printer is applied, for example, stock certificates, various cash vouchers, or a large number of bills to a large number of customers, the printing amount is large and different numbers are used. There is printing of documents that must be printed or the contents. When printing such important documents, it is necessary to completely prevent defects such as duplication and dropout of printed contents, defective printing such as scraping and crushing, and low variations such as line width and shading variations. Quality printing is not allowed, and accurate data must be printed in high quality.

[0005]

However, in such a high-speed printer, it is difficult to prevent the generation of defective printed matter almost completely, and the quality of the printed matter is kept at a high level such as the above-mentioned important documents. It's hard to guarantee. Moreover, in order to completely eliminate such defective printing, there is a demand for inspecting each printed matter, but 10
Obviously, it is impossible to visually inspect a printed matter that is printed at a speed of more than one sheet in real time, and even if inspecting each printed matter after printing, it requires a huge amount of workers and a huge amount of time. Become. Therefore, the printed matter cannot be sufficiently inspected, and the possibility of shipping defective printed matter cannot be eliminated.
Further, when printing such an important document, duplication or omission of printed matter is not allowed, and one printed matter in which desired print contents are appropriately printed must be created.
However, when defective printing occurs and the printing process is stopped midway, it is easily conceivable that a mistake may occur, such as discarding or duplicate printing or missing of the printed material that was being processed.

Therefore, an object of the present invention is to provide a highly reliable printer device capable of finely inspecting print results of individual printed matters, thereby eliminating defective printed matters and performing accurate and high-quality printing. It is in. 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.

[0007]

In order to solve the above-mentioned problems, an inspection means capable of accurately inspecting a print result is provided, and when a defect is detected, a mark is immediately placed on a printed matter,
The printed matter was excluded based on the mark.

Therefore, the printing system of the present invention reads the printed image from the printed means and the printer means for sequentially printing the print data of a predetermined unit such as one destination on the printing paper. Inspecting means for determining whether or not printing is properly performed, and printing a mark indicating that the printed matter is determined to be defective printing at least as a result of the inspection. It has an inspection result printing means and a sorting means for detecting the mark from each printed matter and removing the defective printed matter.

Preferably, the inspection means matches the image data input to the printer means for printing with the image data read from the printed matter to detect a difference, and whether the printing is properly performed. Determine whether or not.
At the time of this matching, the image data may be compressed for matching, or only the partial areas may be matched. Further preferably, the inspecting means determines whether or not the printing is properly performed based on the format information of the input print data. That is,
Based on the format information, by the method of structure analysis, for example, the position of the ruled line, the area where the characters are printed,
A blank area or the like is detected, and it is checked whether or not they are consistent in the read image data or whether the read image data has a similar structure. Of course, both the matching and structural analysis methods may be used together.

Further, specifically, the inspection result printing means has a character, a character string, or a graphic at a predetermined position of the printed matter which is determined not to be properly printed, which indicates that the printed matter is a defective printed matter. , Any one of the bar code or a mark combining them, the selecting means,
The mark is detected from the printed matter, and the printed matter in which the mark is detected is removed. Further, specifically, when the printed matter is a printed matter on which print data having sending data and destination address information is printed for each printed matter sending destination, the inspection result printing means performs printing appropriately. The printed matter determined not to be printed is painted so as to substantially invalidate the destination address information of the printed matter. Of course, for the printed matter determined to be improperly printed, both the printing of the mark and the filling of the destination address information may be performed.

More specifically, in the printer device of the present invention, the printed matter which is not removed by the selecting means is enclosed in an envelope so that the area where the destination address information is printed can be visually observed from the outside. Inspect the addressing information from the outside of the enclosing means and the envelope in which the printed matter is enclosed,
It further has a sent article inspection means for inspecting whether or not the printed matter is inserted in a state in which it can be sent appropriately.

Further, the printed matter processing apparatus of the present invention is a printed matter on which the destination address information and the sending data output from the printer device are printed. If the printing is not properly performed, at least the destination is sent. A shipment that can be properly sent to the destination by enclosing the printed matter further including a mark indicating that the printed matter is a defective printed matter including a mark that substantially invalidates the address information in an envelope. In the printed matter processing apparatus for producing a printed matter, a sorting unit that detects a mark from the printed matter and removes a defective printed matter, and a printed matter that has not been removed by the sorting unit has an area where the destination address information is printed. A printed matter enclosing means that encloses the envelope in a more visible manner, and inspects the destination address information of the printed matter from the outside of the envelope enclosing the printed matter,
It has a sent material inspection means for inspecting whether or not the printed material can be sent based on the destination address information.

This is performed both in the main scanning direction that is the direction of the print head (X direction in FIG. 5) and in the sub scanning direction (Y direction in FIG. 5) that is the same as the transport direction of the printing paper 800. However, with respect to the adjustment in the Y direction, the adjustment of the position of the head 220 and the adjustment of the print timing in the head 220 are performed together so that appropriate printing can be finally performed.

The print image storage unit 240 includes the print unit 20.
This is a memory for storing image data printed on the printing paper 800 by 0, and a dual port RAM is used in the present embodiment. Image data transferred from the control unit 50 via the interface unit 250 is stored in the print image storage unit 240 in a bitmap format.

The interface section 250 includes a control section 50.
This is an interface for transferring print image data transferred from the print image storage unit 240, and is a dedicated serial interface in the present embodiment. The print image data is stored in this interface 2
By 50, the data is transferred at high speed according to the printing speed.

The image reading unit 400 reads the image printed on the printing paper 800 by the printing unit 200 in order to check the print content and print quality, and the inspection image storage unit 4 reads it as bit map image data.
Output to 60. Regarding the image reading unit 400,
This will be described in detail with reference to FIGS. FIG. 8 is a block diagram showing the configuration of the image reading unit 400.

And a control unit 450 _-i . The cue mark detection sensor 410 is provided in the vicinity of the CCD camera 440 of each image reading unit 400, and detects the cue mark recorded at each delimiter of the printed matter of the printing paper 800 that is continuously conveyed. When the cue mark is detected, a signal to that effect is output to the control unit 450.

The encoder section 420 is also provided in the vicinity of the CCD camera 440 of the image reading section 400, and detects the conveyance speed of the printing paper 800 detected by the cue mark detection sensor 410. Encoder unit 42
The configuration of 0 will be described with reference to FIG. The encoder section 420 has an encoder 421, a counter 422, and a speed calculation section 423. The encoder 421 rotates integrally with, for example, the printing paper conveyance roller of the paper conveyance unit 110 and outputs a predetermined pulse corresponding to the rotation angle.
The pulse is counted by the counter 422, and the speed calculation unit 42
In 3, the transport speed of the printing paper 800 is calculated based on the count value within a predetermined time.

The light irradiating section 430 is means for giving an appropriate amount of light to the area of the printing paper 800 for capturing an image with the CCD camera 440 described later. In the present embodiment, the light of the halogen lamp provided in the housing is guided by the fiber cable to irradiate the imaging range of the CCD camera 440. When the CCD camera 440 captures an image, the amount of light required increases as the conveyance speed of the printing paper 800 increases. That is, the printing paper 8
The transport speed of 00 and the required light amount have a substantially proportional relationship. Therefore, the amount of light emitted by the light irradiation unit 430 is controlled based on the transport speed of the printing paper 800 detected by the encoder 421.

The CCD camera 440 reads the printed image and outputs it to the inspection image storage unit 460.

As a whole, the entire range of the print width Wp of the head 220 can be read. A 15 MHz clock is applied to the TDI-CCD sensor 441. Therefore, one line scan time is about 17 μs.

FIG. 1 shows the TDI-CCD sensor 441.
This will be described with reference to FIG. In the TDI-CCD sensor 441, the optical image detected by the element (ROW1) in the first column is imaged on the front surface of the array, and the charges generated by photons are accumulated during the accumulation time corresponding to the scanning of one line.
Collected in the Potential Well. Then, by the clock in the vertical direction (TDI stage direction), the charges are vertically shifted to the next column (ROW2). In the next row, if the same image as before is imaged, the charge generated in ROW2 will be added to the charge from the previous row, and the sensitivity or exposure time will be doubled. Become.

Therefore, if the vertical clock and the TDI transfer direction are synchronized with the motion of the image, TD
It will be integrated by the number of I stages. TD of this embodiment
The I-CCD sensor 441 has 96 TDI stages.
Since it is a step, the detected image is integrated 96 times.
Finally, the integrated data is serially output from the horizontal shift register of the TDI-CCD sensor 441. Also, the TDI-CCD sensor 441 is 2048

The inspection unit 500 includes a print image storage unit 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.

The first compressor 503 and the 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 it exceeds 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 with 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 position of the image data on each image memory 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 feature 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 such as the paper transport unit 110, the printing unit 200, the image reading unit 400, and a heater 620 described later, transports the printing paper, and transfers the printing paper to the printing paper. Controls printing and reading of the printed image so that they can be synchronized properly. In addition, the control unit 600
During the printing operation, when a signal indicating defective printing is input from the inspection unit 500, the defective printing marking unit 630.
Controls the defective print marking unit 630 so that the printing is performed such that the printed matter is invalidated.

The defective print 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 predetermined on a predetermined area of the printed matter, whereby the content already printed on 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 structure 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 printer unit 10 and notifying the operator of the data notified from the printer unit 10. is there. In this embodiment, a general-purpose personal computer is a RS23.
It is used by connecting with a 2C interface. The operation unit 610 also outputs a log file of the inspection result of the printing state and the like. The heater 620 is used in the printer unit 10.
Is a blower of warm air for drying the ink of the printed printing paper 800, which is provided in the subsequent stage of the defective printing marking unit 630.

Next, the operation of the printer unit 10 will be described with reference to FIG.
3 and FIG. FIG. 13 is a diagram showing a state in which print data is printed on the printing paper 800 which is continuous paper in the printer unit 10, and FIG.
FIG. 6 is a diagram showing a state in which a mark is printed on the first page. 13 and 14, the printing paper 800 is
For example, an invoice for telephone charges and the billing address 8
01, various billing information 802, and bill details 803 _{-1 to} 803 _-3 over three pages are printed. Also, the cue mark 804 is displayed at the upper right of the first page of each invoice.
Is printed. With this cue mark, it is possible to know the delimiter position of each invoice from the continuous paper.
Hereinafter, the operation of the printer unit 10 when printing such a bill with the printer unit 10 will be described.

First, print contents, print conditions, and the like are input via the operation unit 610 and a host computer, and each unit of the printer unit 10 is initialized based on the input information. At this time, for example, 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 the defective print marking unit 630 are also set. When the initial setting is completed, the bitmap image data to be sequentially printed is input through the interface unit 250, and the print image storage unit 240
Then, the printing unit 200 prints it on the printing paper 800. 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. When the two images match, it is determined that the printing has been properly performed, and the printed matter is sequentially conveyed as it is and wound up by the winding unit _110-6 .

When a black line 810 as shown in FIG. 14 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 line and 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 print state is defective is input from the inspection unit 500, immediately fills the defective print marking unit 630 in a predetermined area of the invoice and an error indicating the detected defective state. Output the signal to print the code.

As a result, the filling print head 631
Fills the area 821 with 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. The invoice with these patterns and error codes printed thereon is also sequentially wound into the winding unit 110 _{-6 in the} same manner as the invoice normally printed.
It is wound up. Further, the result of the inspection of each bill in the inspection unit 500 is the control unit 600 and the I / F unit
It is output to the control unit 50 via 50. 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. 15 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. 13, 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 unit 923, the control unit 924 tells the printed matter selection unit 925 that the conveyed printed matter is a normal printed matter and 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-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 has been inserted into the envelope and ready to be sent in the enclosing section 20.

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. For example, information indicating the print content to be printed on each printed matter is externally input to the control unit 50, and a print image that can be printed by the printer unit 10 is generated based on the information and output to the printer unit 10. In addition, the control unit 50 manages the print state, inspection result, and the like of the printed matter inspected by the printer unit 10 and the enclosing unit 20,
For example, when the generation of defective printed materials is significant or continuous, a process such as stopping the entire printing system 1 is performed.

Further, based on the data relating to the printed matter inputted from the printer unit 10 and the enclosing unit 20, the properly printed printed matter is properly inserted into the envelope so that the sent matter can be created without duplication and omission. First, inspect and manage. Therefore, the control unit 50 always stores the list of print objects to be printed with the management numbers of the print objects to be printed, and manages each print object. That is, when the printing target is printed by the printer unit 10, the inspection result of the printed matter is input to the control unit 50, and whether the printing is appropriate or inappropriate,
If it is inappropriate, the error code or the like is stored in association with the management number.

When the enclosing section 20 starts to insert the printed matter that has been printed by the printer section 10 into the envelope, two checks are performed by the printed matter selecting section 920 and the sent item inspecting section 940 of the enclosing section 20. The result is input to the control unit 50. Information indicating whether a defective print mark is detected for each print target and whether the print is removed or sent to a subsequent process is input from the print selection unit 920. The control unit 50 records such information in association with the management number and collates it with the inspection result already input from the printer unit 10 to ensure that the properly printed printed matter is sent to the inserter 930. ,
Make sure that the prints that were bad prints have been reliably 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.

Further, from the sent item inspection section 940, the inspection result in the state where the individual printed matter which is the final purpose is inserted into the envelope is inputted. Normally, as the inspection result, the management number of the printed matter that has been appropriately processed is input, so that the control section 50 terminates the processing of the printed matter of that management number and substantially removes it from the management target. Further, when the detection of a 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. Further, based on the inspection result for each printed matter stored in the control unit 50, processing such as identification of the printed matter and investigation of the cause of defective printing is performed, and if such defective printed matter is detected continuously, printing is performed. Stop processing is also performed.

When a series of printings such as a printing process on one roll of paper is completed, the control unit 50 still remains as a management target, that is, it is removed by defective printing and the final printed matter is not generated. Extract printed material. Then, the control unit 50 causes the reprint printer unit 40 to reprint the printed matter. At this time, since the print image data and the like necessary for printing are stored in the control unit 50, this is read out and the reprint printer unit 4 is read.
Output to 0. The control unit 50 causes the encapsulation unit 20 to output the printed matter to be managed when the printed matter to be managed has been exhausted or the printed matter as a result of the reprinting has been received in response to a signal input from the sent-goods inspection section 940 that the processing has been appropriately completed. The process is terminated when the series of processes are completed by throwing in.

To summarize the operation of the printing system 1 described above, first, in the printer unit 10, different data for each printed matter is sequentially printed at high speed, and the printed image is photographed by the camera to determine the printing state. Check the print contents. 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. When the printing is completed, the printed matter is stored in the enclosing unit 20.
The continuous paper is sequentially cut and separated into one printed matter. Then, the defective print mark printed on the printer unit 10 is checked,
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 50 is provided with the inspection result for the printing performed by the printer unit 10, the enclosing unit 2
The result of the first sorting performed at 0, the result of checking the final printed matter, and the like are sequentially input. By associating these with each other, defective prints can be reliably discarded, normal prints can be properly inserted into the envelope for output, and there is no abnormal state or contradiction between these processes. Are always checked. And further, regarding the printed materials discarded as defective printed materials,
Printing is performed in the reprint printer unit 40, and again inserted into the envelope in the enclosing unit 20 to generate an appropriate delivery item.

As described above, in the printing system 1 of this 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. In addition, the printed matter is immediately inspected and the printing state is checked, and the state of the printed matter (whether it has been discarded or has proceeded to a subsequent process as a valid printed matter) is always grasped during the processing, and the printed matter is further printed on the envelope. Has undergone a final check after being inserted. Therefore, it is possible to almost completely prevent the defective printing from being output to the outside and the printed matter from being missing or overlapping.

Further, in the unlikely event that a defective printed matter is mixed with a normal printed matter and goes out, in the printing system 1 of the present embodiment, such a defective printed matter is not dealt with. , The important matter column of the printed matter is filled. Therefore, the defective printed matter can no longer be used for its original purpose, and accidents such as misdelivery of a bill can be completely prevented. Further, since the printed matter that cannot be properly processed and remains is separately printed by the second printer device that has a low speed and few defective prints, it is possible to appropriately and efficiently deal with such defective printed matter. In the end, a large amount of printed matter can be efficiently and accurately created.

That is, it is possible to perform high-speed printing while inspecting the print content and the print state, it is possible to almost completely avoid troubles such as duplication and dropout of print content, and high reliability of important documents. Can be printed with. Also, if defective printing occurs,
Since the printing process can be stopped immediately, defective printed matter can be minimized. Furthermore, not only the print head itself is defective, but also the print content and print quality can be comprehensively inspected, such as the conveyance status of the print paper and stains due to a defective gap adjustment between the print paper and print head. Can print.

The present invention is not limited to this embodiment, and various modifications can be made. For example, the print medium is not limited to the continuous paper as shown in the present embodiment, but may be cut paper. In that case, the roll paper supply unit 110 _-1 of the paper transport unit 110 may be used as a hopper unit to supply the cut paper. In each unit of the roll paper supply unit 110 _-1 , an edge detector may be provided. It may be provided and positioned in the sub-scanning direction. Of course, the print medium may be a print medium made of a material other than paper, and the handling mechanism of the print medium may have an arbitrary configuration according to the print medium.

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 for 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, 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. 6 (B), it may be possible to mark whether or not the explanatory text is valid with respect to the explanatory text that clearly indicates that the printed matter is not effective. Alternatively, a barcode or the like may be used.

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, but may be any type of heads. Further, the printer unit 10 is not limited to a printer unit that prints in black and white two colors, but is also applicable to a printer unit 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 for defective printing in the inspection unit 500, and the like,
The present invention is not limited to this embodiment, and may have any configuration.
