Description

The present invention relates to an image processing apparatus that generates a coded image.

Image data generated by a computer may be printed using a printing device that is not connected to a network. In such a case, image data is stored in a storage medium such as a USB (Universal Serial Bus) memory, the storage medium is connected to a printing device, and then printing is performed based on the image data stored in the storage medium.

Here, from the viewpoint of security, data transfer in the storage medium may be prohibited. In such a usage environment, an image (encoded image) in which data to be printed by a printing apparatus is encoded may be printed on paper and carried.

For example, in Patent Document 1, image data is two-dimensionally coded (encoded), the two-dimensional code is printed on a paper medium, and the printed two-dimensional code is read by a scanner and decoded (decoded). A two-dimensional code reader for printing image data is disclosed.

Japanese Unexamined Patent Publication No. 2009-6447

FIG. 1 is an explanatory diagram showing a schematic configuration of a printing system having an image processing apparatus according to the first embodiment of the present invention.

(Overall configuration of printing system)
As shown in FIG. 1, the printing system of the present embodiment includes an image processing device 1, an inkjet printing device 5, and a stencil printing device 9. Here, the image processing device 1 is a device that generates image data for reading by the scanner unit described below. The image processing device 1 and the inkjet printing device 5 are installed in the data generation room 801, and the stencil printing device 9 is installed in the printing room 803 that is physically separated from the data generation room 801. In 801 and 803 in each room, each device is connected, but not connected across the rooms. That is, the image processing device 1 and the inkjet printing device 5 are connected to each other so that data can be transferred by a printer cable or the like, but the image processing device 1 and the stencil printing device 9 are physically and electrically connected by a printer cable or a network cable or the like. Not connected to.

In such a configuration, when printing is performed by the stencil printing device 9 using the image original image created by the image processing device 1, the user does not leak the contents of the original image between the chambers 801 and 803. Causes the image processing device 1 installed in the data generation room 801 to generate encoded image data in which all of the original images are encoded. Then, based on the coded image data, the inkjet printing device 5 is made to print the coded image on the paper. As a result, a coded manuscript is obtained. The user can obtain the decoded printed matter by having the scanner unit (reading device) 3 of the stencil printing device 9 installed in the printing chamber 803 read the coded document and decoding the scanned coded document. ..

The stencil printing apparatus 9 sandwiches a master made on a rotating drum with a clamp and winds it, then feeds the paper to the drum, and press-contacts the supplied paper to the drum by a press roll while rotating the drum. Print.

In the present embodiment, the stencil printing device 9 has a control unit 90, and the control unit 90 has a scanner unit 3 that reads a coded document on which a coded image is printed and outputs coded document data, and a scanner. A printer unit 96 that prints (records) a printed image on a paper (single-sided or double-sided) based on the decoded original image of the encoded original data output from the unit 3 is provided.

The control unit 90 of the stencil printing apparatus 9 has a CPU 95. The CPU 95 decodes the coded original data read by the scanner unit 3 to generate an original image, and prints the original image on paper in the printer unit 96 under the specified conditions.

Further, the control unit 90 is connected to an operation panel 97 composed of an operation screen and a touch panel covering the operation screen.

The control unit 90 is provided with a RAM 92, and the RAM 92 temporarily outputs the encoded original data read by the scanner unit 3 and the decoded original image until it is output to the printer unit 96. It will be remembered.

Further, the control unit 90 is provided with an external storage device 93, and the external storage device 93 is connected to the CPU 95. The external storage device 93 is provided with a plurality of areas for storing the original image and setting information transferred from the RAM 92 described above. Other programs, data, etc. are stored in the ROM 17.

FIG. 2 is a diagram showing a configuration of a scanner unit 3 included in the stencil printing apparatus 9.

As shown in FIG. 2, the scanner unit 3 includes a lower unit 31 and an upper unit 32 installed on the lower unit 31.

The lower unit 31 has a platen 33 and an image reading unit that reciprocates along a plurality of axes 33a (only one axis is shown in FIG. 2) arranged parallel to the platen 33 in a direction orthogonal to FIG. 34 is provided. The image reading unit 34 is stretched in a direction orthogonal to the paper surface. The reading unit 34 has a carriage 34a that slides along the axis. In the embodiment described later, the carriage 34a is movably supported by the guide rail 33a along the platen 33 so as to scan the coded document S set (fixed) on the platen 33.

The image reading unit 34 includes a light source lamp 34b, an optical system 34c such as a condenser lens and a mirror that forms an image, and a photoelectric conversion unit 34d such as a CCD. Like the image reading unit 34, the light source lamp 34b, the optical system 34c such as a condensing lens and a mirror that forms an image, and the photoelectric conversion unit 34d such as a CCD are extended in a direction orthogonal to the paper surface and are orthogonal to the paper surface. Read the image on the document S in the direction of More specifically, the optical system 34c deflects the reflected light of the light emitted from the light source on the coded document S conveyed through the upper unit 32 with a mirror, and forms an image on the photoelectric conversion unit 34d with a condenser lens. To do. The photoelectric conversion unit 34d reads the imaged image as an electrical signal.

The upper unit 32 is formed with a substantially U-shaped transport path P (P1, P2) that guides the coded document S from the document tray 35 to the output tray 36. The transport path P guides the encoded document S from the document tray 35 to the reading position by the image reading unit 34 to the paper feed path P1 and the encoded document S from the reading position by the image reading unit 34 to the output tray 36. It is composed of a paper feed path P2 and a circulation path P4 that switches back the encoded document S whose tip is carried out onto the paper output tray 36 to reverse the transport direction and then guides the encoded document S to the paper feed path P1 again. ..

A pickup roller 37 is arranged on the document tray 35 so as to be vertically movable and supported by a swing arm 38. A paper feed roller 49a is axially supported on the other side of the swing arm 38. A separation roller 49b is pressure-welded to the paper feed roller 49a, and the coded documents S conveyed by the pickup roller 37 are separated from the document tray 35 one by one and carried out to the downstream side by the paper feed roller 49a.

The paper feed path P1 is provided with a resist roller 39 composed of a drive roller 39a and a driven roller 39b, and a first lead roller 41 is arranged on the downstream side of the resist roller 39. The encoded document S conveyed through the paper feed path P1 is skew-corrected by abutting against the resist roller 39 and sent to the first lead roller 41 on the downstream side.

An edge sensor 42 is arranged near the upstream side of the first lead roller 41 on the paper feed path P1, and the edge sensor 42 is the tip or rear of the coded document S conveyed on the paper feed path P1. Detect the edge.

A second lead roller 43 and a third lead roller 44 are arranged further downstream on the paper feed path P1 to convey the encoded document S on the paper feed path P2 at a predetermined speed and timing.

A paper ejection roller 45 is provided at the paper ejection port which is the most downstream of the paper feeding path P2, and a path switching flapper 46 is provided near the upstream side of the paper ejection roller 45. The path switching flapper 46 sets whether to guide the coded document S from the paper feed path P2 to the paper output tray 36 or to the circulation path P4 by an operating solenoid (not shown).

Further, by reversing the paper ejection roller 45 in the nip state immediately before ejecting the encoded document S to the paper ejection tray 36 and switching the path switching flapper 46, the encoded document S is guided to the circulation path P4 and fed. The roller 47 can guide the paper feed path P1 to the resist roller 39.

In this way, when the paper ejection roller 45 is reversed in the document nip state, the encoded document S is conveyed with its front end and rear end inverted with respect to the conveying direction.

3 and 4 are explanatory views illustrating the operation of the scanner unit 3 included in the stencil printing apparatus 9.

As described above, in the case of single-sided reading, the coded original S is conveyed from the original tray 35 through the paper feed paths P1 and P2, and is discharged onto the output tray 36.

In such an apparatus configuration, when the coded document S reaches the positions shown in FIGS. 3 (a), 3 (b), 4 (a), and 4 (b) (states 1 to 1 below). In the state of 4), the transport speed of the coded document S may change, and the image may not be properly read by the photoelectric conversion unit 34d.

State 1: When the tip of the coded document S is abutted against the second reed roller 43 by the transfer between the resist roller 39 and the first reed roller 41 (see FIG. 3A).

State 2: When the tip of the coded document S is abutted against the path switching flapper 46 by the transfer between the resist roller 39, the first lead roller 41, and the second lead roller 43 (see FIG. 3B).

State 3: When the rear end of the encoded document S passes through the resist roller 39 (see FIG. 4A).

State 4: When the rear end of the encoded document S passes through the first lead roller 41 (see FIG. 4B).

As described above, depending on the device configuration of the scanner unit 3, there is a possibility that the conveyed state may change when the coded document S is in the states 1 to 4. At this time, the position on the document on which the photoelectric conversion unit 34d reads the coded document S is called the change position (that is, the “change position” means that when the document is in any of the above states 1 to 4, the image reading unit 34 It means the position on the coded document S to be read.) The "position on the coded document S" means, for example, the distance from the tip of the document S in the document transport direction. ).

By the way, as described above, the states 1 to 4 are states in which the coded document S exists at a position on the transport path where the transport state may change. Therefore, the "change position" is defined as "a position on the coded document S read by the image reading unit 34 when the coded document S is present at a position on the transport path where the transport state may change". Can be expressed.

As can be understood from FIGS. 3 and 4, the change position is the distance between the reading position of the image reading unit 34 and the rollers 43, 46, 39, 41 when the scale is shaken along the transport path. It is determined by (scale).

If the coded image is read while the coded document S is in the changing position, the read coded image may be distorted and may not be acquired as an appropriate image.

Therefore, the image processing device 1 generates coded image data that can be appropriately decoded even when the transport state of the scanner unit 3 to be read changes.

Returning to FIG. 1, the image processing device 1 is composed of a general-purpose computer such as a PC (personal computer). The image processing device 1 includes a CPU 16 that executes various processes based on a control program. Further, the CPU 16 is connected to a RAM 18 that functions as a working area, a ROM 17 that stores data, and the like, and is connected to various devices via various interfaces. Specifically, the CPU 16 includes an input unit 19 composed of a keyboard, a mouse, and the like, an output unit 20 composed of a liquid crystal display, and an external storage device 21 such as a large-capacity storage device via various interfaces. It is connected.

The external storage device 21 contains an application program for generating a manuscript image including a printed image such as a document or an image, a printer driver program of the inkjet printing device 5, and a paper transport state for each scanner unit of the stencil printing device 9. A change position table that stores changing positions (on the document) is stored. Further, the external storage device 21 also secures a database area for storing a manuscript image generated by using an application program, coded image data obtained by encoding the manuscript image, and print setting information. There is. Here, the print setting information includes information necessary for normal printing, such as a print mode, a size of a coded image, a resolution, a thickness of a print paper, a size of a print paper, and a print direction.

The CPU 16 is an arithmetic unit composed of a processor, a memory, and other peripheral devices. The acquisition means 161, the coding means 162, and the image processing means 163 are mounted on the CPU 16.

When the coded print request for the original image is input from the input unit 19, the acquisition means 161 acquires the thickness of the paper from the print setting information. Here, the coded printing request is a request for encoding a manuscript image to generate coded image data and causing the inkjet printing apparatus 5 to print the coded image on paper based on the coded image data. Is. The user selects this coded printing when he / she wants to print a highly confidential manuscript image with high security so that the content cannot be determined even if a third party sees it and the third party does not print it. To do.

When the user performs an operation requesting coded printing, the coding means 162 acquires the manuscript image generated by the manuscript application or the like and encodes the manuscript image into a two-dimensional code or a three-dimensional code.

FIG. 5 is a diagram illustrating coding of the original image and decoding of the coded image.

When the manuscript image 101 as shown in FIG. 5 (a) is generated by the manuscript application, the coding means 162 encodes the manuscript image 101 to encode the pre-processed coded image data 103 shown in FIG. 5 (b). To generate. The pre-processed coded image data 103 includes a coded image 401 and a marker 402 indicating a position to read the coded image 401.

In order to prevent the scanner unit 3 from reading the coded image at the change position, the image processing means 163 displays the coded image 401 of the pre-processed coded image data 103 encoded by the coding means 162 for each predetermined area. The coded image data 105 is generated by dividing into. Specifically, the image processing means 163 divides the coded image 401 based on the change position table stored in the external storage device 21 so that the coded image does not overlap the change position, and FIG. 5 (c). ), The coded image data 105 including the coded images 401a to 401d is generated. The coded image data 105 includes markers 402a to 402d indicating positions for reading the coded images 401a to 401d, respectively.

For the sake of explanation, FIG. 5 (c) shows the change positions 201 to 207. The change position 201 is a position where the image is read by the image reading unit 34 in the above-mentioned state 1, and the change position 203 is a position where the image is read by the image reading unit 34 in the above-mentioned state 2. The change position 205 is a position where the image is read by the image reading unit 34 in the above-mentioned state 3, and the change position 207 is a position where the image is read by the image reading unit 34 in the above-mentioned state 4.

As shown in FIG. 5C, by dividing the coded image 401 into the coded images 401a to 401d, blank areas 301 are formed before and after the transport direction of the coded document S around the change position 201. It is provided. Similarly, for the change positions 203 to 207, blank areas 303 to 307 are provided before and after the transport direction of the coded document S.

The inkjet printing apparatus 5 prints based on the coded image data 105 shown in FIG. 5C to obtain a coded original S.

As described above, when the user causes the scanner unit 3 of the stencil printing device 9 installed in the printing chamber 803 to read the coded document S, the stencil printing device 9 decodes the scanned coded document S and shows the figure. The printed matter 107 shown in 5 (d) is obtained.

In this way, since the image processing means 163 processes the coded image so that the coded image does not overlap with the changed position, it is possible to prevent the scanner unit 3 from reading the coded image at the changed position. As a result, the stencil printing apparatus 9 can appropriately decode the printed matter, so that the printed matter 107 on which the original image 101 is printed can be obtained.

<Embodiment 2>
In the first embodiment, the image processing means 163 generates the coded image data 105 in which the coded images 401a to 401d obtained by dividing the coded image 401 of the pre-processed coded image data 103 are arranged by providing blank areas 301 to 307. To do.

In the second embodiment, the image processing means 163 divides the coded image so that the blank area becomes wider as the degree of influence on the reading of the coded image increases.

Since the printing system of the second embodiment has the same configuration as the printing system of the first embodiment shown in FIGS. 1 to 3, the description thereof will be omitted.

FIG. 6 shows an example of the influence degree table stored in the external storage device 21 of the image processing device 1.

As shown in FIG. 6, the external storage device 21 stores an influence degree table in association with the degree of influence on the reading of the coded image corresponding to the paper thickness and the change positions 201 to 207. Here, the degree of influence is divided into three stages, "high degree of influence", "medium influence", and "small degree of influence", but the degree of influence is not limited to three. Further, as for the degree of influence, appropriate coefficients are set according to "large degree of influence", "medium influence degree", and "small degree of influence" so that the blank area becomes wider as the degree of influence increases.

As the paper thickness becomes thicker, the impact in the states 1 to 4 becomes larger, so that the degree of influence becomes larger. Further, the closer the source of the impact in the states 1 to 4 is to the photoelectric conversion unit 34d, the greater the degree of influence. For example, since the second reed roller 43, which is the source of the state 1, is closer to the photoelectric conversion unit 34d than the path switching flapper 46, which is the source of the state 2, the degree of influence is set to be large.

The image processing means 163 extracts from the influence degree table the degree of influence corresponding to the paper thickness and the change position acquired by the acquisition means 161. Then, the image processing means 163 divides the coded image so that the larger the degree of influence, the wider the blank areas provided before and after the paper transport direction around the change position.

FIG. 7 shows an example of coded image data generated when the paper thickness is “thin”.

In the influence degree table shown in FIG. 6, when the paper thickness is "thin", the influence degree of the change position 201 is "large influence", the influence degree of the change position 203 is "influenced", and the change position is changed. The degree of influence of 205 is “small influence”, and the degree of influence of the change position 207 is “under influence”.

Therefore, in the example shown in FIG. 7, since the degree of influence of the change position 201 is “large influence”, the blank areas 501 provided before and after the change position 201 in the paper transport direction are widely provided. .. Since the degree of influence of the change positions 203 and 207 is “under influence”, the blank areas 503 and 507 provided before and after the paper transport direction around the change positions 203 and 207 are provided as a medium size. ing. Since the degree of influence of the change position 205 is "small influence", the blank areas 505 provided before and after the change position 205 in the paper transport direction are narrowly provided.

In this way, the image processing means 163 divides the coded image so that the blank areas 501 to 507 provided before and after the paper transport direction become wider around the change positions 201 to 207 as the degree of influence increases. The influence at the change position can be further reduced. As a result, the stencil printing apparatus 9 can appropriately decode the printed matter, so that a printed matter on which the original image is printed can be obtained.

Here, the image processing means 163 divides the coded image so that the blank areas 501 to 507 provided before and after the paper transport direction become wider around the change positions 201 to 207 as the degree of influence increases. , Not limited to this. For example, the image processing means 163 divides the coded image so that the thicker the paper thickness acquired by the acquisition means 161 is, the wider the blank areas provided before and after the paper transport direction around the change position. May be good.

<Embodiment 3>
In the first embodiment, the image processing means 163 generates the coded image data 105 in which the coded images 401a to 401d obtained by dividing the coded image 401 of the pre-processed coded image data 103 are arranged by providing blank areas 301 to 307. did.

In the third embodiment, the image processing means 163 may generate the coded image data in which the position of the coded image of the pre-processed coded image data is moved.

FIG. 8 is a diagram showing an example of pre-processed coded image data and coded image data processed by the image processing means 163 in the third embodiment.

The coding means 162 encodes the original image to generate the pre-processed coded image data 601 shown in FIG. 8A. The pre-processed coded image data 601 includes a coded image 602 and a marker 603 indicating a position to read the coded image 602.

Then, as shown in FIG. 8B, the image processing means 163 moves to the coded image 602a so that the coded image 602 does not overlap the change positions 201 to 203, so that the scanner unit 3 moves to the coded image 602a at the change position. It is possible to avoid reading the coded image 602a. As a result, the stencil printing apparatus 9 can appropriately decode the printed matter, so that a printed matter on which the original image is printed can be obtained.

In the first to third embodiments, the image processing means 163 does not overlap the coded image at the change position where the transport state of the paper (coded document S) on which the coded image is printed changes. Was processed, but it is not limited to this.

For example, when the scanner unit 3 and the printer unit 96 operate in conjunction with each other, when the scanner unit 3 reads the coded document S, there may be a change position where an impact is always generated at the same position. For example, as described above, the printer unit 96 of the stencil printing apparatus 9 sandwiches the master plate-making on the rotating drum with a clamp and winds it, then feeds the paper to the drum and supplies the paper while rotating the drum. Printing is performed by pressing the paper against the drum.

When the operation of sandwiching and winding the master with a clamp is executed in conjunction with the operation of scanning the coded document S by the scanner unit 3, the change positions are always the same.

Therefore, the external storage device 21 further stores the position on the paper read by the scanner unit 3 as the change position when the reading state of the coded image changes according to the device linked with the scanner unit 3.

Then, when the image processing means 163 reads the paper on which the coded image is printed while the stencil printing device 9 is interlocked with the scanner unit 3, the coded image does not overlap with the change position stored in the external storage device 21. As described above, the coded image is processed to generate the coded manuscript S.

As a result, the stencil printing apparatus 9 can appropriately decode the printed matter, so that a printed matter on which the original image is printed can be obtained.
