Description

[Technical field]

[0001] The present invention relates to an image inspection apparatus, an image forming apparatus, an image forming system, an image inspection method, and a program. [Background technology]

[0002] Conventionally, an image formed on a sheet by an image forming device is read, and the read image is compared with a reference image to inspect the image. For example, in Patent Document 1, the first read image is used as the reference image, and the second and subsequent read images are used as inspection images to inspect the image.

[0003] In addition, in some cases, instead of just the first page, all images in a proof-printed copy of a job consisting of multiple pages per copy are used as the reference image, and the images scanned at the time of actual printing after the reference image has been registered are used as the inspection target. Specifically, the proof image for all copies is output, and the user checks the proof image. If there are no problems, the image is registered as the reference image. If necessary, the area to be inspected is set. After that, the job to be inspected is executed, and the reference image is used to inspect the number of copies set for the job. That is, each time an inspection is performed, the user first checks whether the proof image can be officially adopted as a reference image for the inspection, and then starts the inspection. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings, however, the scope of the present invention is not limited to the illustrated examples.

[0015] [First embodiment: Overview of image forming system] First, the configuration of an image forming system 100 will be described with reference to FIGS. Fig. 1 is a configuration diagram of an image forming system 100 according to an embodiment of the present invention. Fig. 2 is a block diagram showing the functional configuration of the image forming system 100. The image forming system 100 includes an image forming apparatus 10 that performs an image forming process on a sheet P, and an image inspection apparatus 20 that inspects the sheet P on which an image has been formed by the image forming apparatus 10.

[0016] [Image forming equipment] The image forming apparatus 10 forms an image on a sheet P in accordance with an image formation instruction received from a PC (Personal Computer) or the like via a communication network. The image forming apparatus 10 conveys the sheet P on which the image has been formed to an image inspection apparatus 20. The image forming apparatus 10 includes a CPU 11, a ROM (Read Only Memory) 12, a RAM (Random Access Unit) 13, a memory unit 14, a paper feeding unit 15, an image reading unit 16, an image forming unit 17, a paper inversion unit 18, an operation display unit 19, a communication I / F (InterFace) 110, etc.

[0017] The CPU 11 reads out a program stored in the ROM 12, loads it into the RAM 13, and controls the operation of each part of the image forming apparatus 10 in cooperation with the loaded program. The ROM 12 is configured from a non-volatile semiconductor memory or the like, and stores the system program, various processing programs that can be executed on the system program, various data, and the like. The RAM 13 is configured from a volatile semiconductor memory or the like, and forms a work area for temporarily storing programs read from the ROM 12, input or output data, parameters, and the like during various processes executed by the CPU 11.

[0018] The storage unit 14 is configured with a HDD (Hard Disk Drive), a non-volatile semiconductor memory, etc., and stores various data.

[0019] The paper feed unit 15 has multiple paper feed trays T1 to T3 that can store paper P of different sizes, types (paper grades), basis weights, etc., and supplies the paper P stored in the specified paper feed tray T1 to T3 to the image forming unit 17.

[0020] The image reading unit 16 reads an original document and generates image data. Specifically, the image reading unit 16 reads light that is irradiated from a light source and reflected by the original document using a CCD (Charge Coupled Device) image sensor or the like.

[0021] The image forming unit 17 forms an image on the paper P. The image forming unit 17 charges a photoconductor in a charging unit, exposes and scans the photoconductor with a laser beam emitted from an exposure unit based on image data to form an electrostatic latent image, develops the electrostatic latent image with toner in a developing unit, transfers the toner image to the paper P in a transfer unit, and fixes the toner image to the paper P in a fixing unit (fixing device).

[0022] The paper inverting section 18 inverts the paper that has passed through the image forming section 17, and conveys it to the image forming section 17 again.

[0023] The operation display unit 19 includes a display unit configured with an LCD (Liquid Crystal Display) that displays various screens, and an operation unit configured with a touch panel and various keys stacked on the display unit. The operation display unit 19 outputs operation signals input by touch operations or key operations to the CPU (Central Processing Unit) 11.

[0024] The communication I / F 110 is composed of a NIC (Network Interface Card), a modem, etc., and transmits and receives data to and from the image inspection device 20 and a PC (Personal Computer).

[0025] [Image inspection equipment] The image inspection device 20 reads and inspects the image on the paper P conveyed from the image forming device 10. The image inspection device 20 includes a CPU 21, a ROM 22, a RAM 23, a storage unit 24, a paper transport unit 25, an operation display unit 26, an image reading unit 27, a communication I / F 28, and the like.

[0026] The CPU 21, the ROM 22, and the RAM 23 are similar to the CPU 11, the ROM 12, and the RAM 13, except that the object controlled by the CPU 21 is the image inspection device 20. The CPU 21 cooperates with the image reading unit 27 to function as an inspection unit that inspects the image formed on the recording medium based on a reference image used for inspecting the image formed on the recording medium. The CPU 21 functions as a control unit that executes a proof output mode for forming a proof image based on a job on the recording medium. The CPU 21, as a control unit, determines whether or not execution of the proof output mode has been completed, and when it is determined that execution of the proof output mode has been completed, executes an automatic inspection mode in which the inspection unit starts image inspection.

[0027] The storage unit 24 is configured with a HDD, a non-volatile semiconductor memory, or the like, and stores various data.

[0028] The paper transport section 25 is composed of a plurality of transport rollers provided along a transport path, and transports the paper P carried in from the image forming apparatus 10.

[0029] The operation display unit 26 includes a display unit configured with an LCD for displaying various screens, and an operation unit configured with a touch panel and various keys stacked on the display unit. The operation display unit 26 outputs operation signals input by touch operations or key operations to the CPU 21. The operation display unit 26 functions as a setting unit for setting the automatic inspection mode on / off.

[0030] The communication I / F 28 is composed of a NIC, a modem, and the like, and transmits and receives data to and from the image forming apparatus 10 .

[0031] The image reading unit 27 reads the paper P conveyed from the image forming apparatus 10 and generates image data. Specifically, the image reading unit 27 reads light irradiated from a light source and reflected by a document using a CCD (Charge Coupled Device) image sensor or the like. The image reading unit 27 functions as a reading unit that reads the proof image. The image reading unit 27 is capable of not only reading the paper P, but also detecting abnormalities such as stains, streaks, glowing spots, and alignment errors with a reference image.

[0032] [Inspection process flow] The flow of the inspection process executed by the CPU 21 will be described with reference to Fig. 3. The inspection process is started, for example, when the CPU 21 acquires job information. The job information includes inspection information, which will be described later, and information such as the number of pages and the number of copies. In the inspection process, two jobs are executed: a proof output job and an inspection job. In a proof output job, the image forming device 10 forms a proof image on one copy of paper P, and the image inspection device 20 reads the proof image on the paper P and stores the proof image as a reference image in the storage unit 24 (reference image registration) (proof output mode). The proof output mode may be completed when the reference image is registered, or when the proof image is formed on the paper. In the inspection job, an image to be inspected is formed on paper P for the number of copies set by the user in the job information, and the image inspection device 20 reads the paper P and inspects it by comparing the read image with a reference image. When the image inspection device 20 is set to the automatic inspection mode, the image inspection device 20 transitions to the automatic inspection mode in which an inspection job is automatically started as soon as the execution of the proof output mode is completed. In the case of variable printing, one unit of repeated image formation is imaged in the proof output job. For example, suppose that two copies of 10 pages are imaged, and the repeated portion of the 10 pages is repeated in units of two pages. In this case, the proof output job forms images for two pages as proof images.

[0033] Here, the job information setting, particularly the examination information setting, will be described with reference to the job setting screen 26A shown in FIG. Area A1 is an area for setting inspection information, which includes automatic inspection mode information, reference image information, deletion information at the end, inspection level information, automatic image quality correction information, inspection area setting information, and the like. The automatic inspection mode information is information that indicates whether or not an inspection job is to be started automatically (ON / OFF) after a proof output job is completed. The reference image information is image information to be formed on the paper P as a reference image. The deletion information at the end is information indicating whether or not (ON / OFF) the reference image data is to be deleted from the storage unit 24 after the inspection process. The inspection level information is information that indicates the accuracy of the inspection process. For example, the inspection level information is "strict", "normal", "lenient", etc. The automatic image quality correction information is information indicating whether or not the image read by the image reading unit 27 is to be automatically corrected (ON / OFF). The inspection area setting information is information indicating whether or not to set an inspection area on the paper P (ON / OFF), and position information of the inspection area on the paper P. The former is set in the area A1. The latter is set in the area A2, which will be described later. Area A2 is an area where position information of the inspection area on the paper P is set. Area A3 is an area for setting job information other than the examination information. Job information other than the inspection information includes, for example, not only the number of pages and number of copies mentioned above, but also paper size, paper type, image forming surface, paper output tray, whether or not stapling is performed, whether or not punching is performed, tone, and cutting settings. The button B1 is a button for deciding on the set job information.

[0034] Returning to the description of the inspection process. It is assumed that the job settings have already been made by the user. First, when the CPU 21 of the image inspection device 20 receives a proof output job start instruction input by the user from the operation display unit 26, the CPU 21 causes the image forming device 10 to start a proof output job (step S1). Then, the CPU 11 of the image forming apparatus 10 causes the image forming unit 17 to form one copy of a proof image on the paper P based on the proof image information received from the image inspection device 20. In the case of variable printing, the image is formed for one unit. During image formation, the CPU 21 displays the execution screen 26B shown in Fig. 5 on the operation display unit 26. In the area A4 on the execution screen 26B, the user can change the automatic inspection mode information in the job information. When the information is changed, the CPU 21 changes the automatic inspection mode information and registers it in the storage unit 24.

[0035] Next, the CPU 21 causes the image reading unit 27 to read the proof image formed on the paper P conveyed from the image forming apparatus 10 (step S2). Next, the CPU 21 stores the read proof image as a reference image in the storage unit 24 (registers the reference image) (step S3).

[0036] Next, the CPU 21 determines whether to automatically start an inspection job after registering the reference image (steps S4 to S7). If the user always wants to start an inspection job automatically, the inspection process can be simplified by omitting steps S4 to S7. In step S4, the CPU 21 determines whether the automatic inspection mode information is ON in the job information. If the automatic inspection mode information is ON (step S4; YES), the CPU 21 advances the inspection process to step S5. If the automatic inspection mode information is OFF (step S4; NO), the CPU 21 advances the inspection process to step S8. In step S5, the CPU 21 judges whether the inspection area setting information is ON in the job information. If the inspection area setting information is ON (step S5; YES), the CPU 21 advances the inspection process to step S6. If the inspection area setting information is OFF (step S5; NO), the CPU 21 advances the inspection process to step S8. In step S6, CPU 21 determines whether the number of pages used to create the reference image matches the number of pages per copy to be output in the inspection job (step S9). If they match (step S6; YES), CPU 21 advances the inspection process to step S7. If they do not match (step S6; NO), CPU 21 advances the inspection process to step S8. If they do not match (step S6; NO), there is a high possibility of variable printing, and it becomes necessary to set an inspection area for the variable area of ​​the reference image. Therefore, CPU 21 advances the inspection process to step S8 and does not automatically start the inspection job. In step S7, the CPU 21 determines whether or not an abnormality such as dirt was detected during the previous inspection job. If no abnormality was detected (step S7; NO), the CPU 21 advances the inspection process to step S9. If an abnormality was detected (step S7; YES), the CPU 21 advances the inspection process to step S8. If an abnormality such as dirt was detected during the previous inspection job, there is a high possibility that an abnormality such as dirt will be detected again in the inspection job, so the CPU 21 advances the inspection process to step S8 and does not automatically start the inspection job.

[0037] In step S8, the CPU 21 suspends the job. Thereafter, the user checks the sheet P on which the reference image has been formed (reference image check), and sets an inspection area on the job setting screen 26A shown in FIG. 4, and the CPU 21 acquires the setting contents. When the user issues an instruction to resume the job, the CPU 21 advances the inspection process to step S9.

[0038] In step S9, the CPU 21 causes the image forming apparatus 10 to start an inspection job. Specifically, the CPU 11 of the image forming apparatus 10 causes the image forming section 17 to form the inspection image on the paper P for the number of copies set by the user in the job information. During image formation, CPU 21 causes operation display unit 26 to display execution screen 26C shown in Fig. 6. In the case of automatic inspection (steps S4 to S7; YES), CPU 21 causes area A5 to display "automatic inspection in progress." CPU 21 may also cause area A5 to display the inspection level.

[0039] Next, the CPU 21 causes the image reading unit 27 to read the inspection image formed on the paper P conveyed from the image forming apparatus 10 (step S10).

[0040] Next, the CPU 21 compares the reference image data registered in the storage unit 24 in step S3 with the read inspection image data (step S11). When an inspection area has been set, the CPU 21 compares the images of the area of ​​the paper P that corresponds to the inspection area between the reference image data and the inspection image data.

[0041] Next, the CPU 21 judges whether the comparison result in step S11 is good (step S12). If the comparison result is good (step S12; YES), the CPU 21 ends the inspection process. If the comparison result is not good (step S12; NO), the CPU 21 advances the inspection process to step S13.

[0042] Next, the CPU 21 causes the operation display unit 26 to display an error (step S13), and ends the inspection process.

[0043] [Second embodiment: Overview of image forming apparatus] The configuration of the image forming apparatus 30 will be described with reference to FIGS. Fig. 7 is a configuration diagram of an image forming apparatus 30 according to an embodiment of the present invention, and Fig. 8 is a block diagram showing a functional configuration of the image forming apparatus 30. The image forming apparatus 30 is obtained by adding a configuration corresponding to the image reading unit 27 of the image inspection device 20 to the configuration of the image forming apparatus 10 of the first embodiment. In the image forming device 30, the configuration corresponding to the image reading unit 16 of the image forming device 10 of the first embodiment is designated as a first image reading unit 36, and the configuration corresponding to the image reading unit 27 of the image inspection device 20 of the first embodiment is designated as a second image reading unit 311. The other components of the image forming apparatus 30, such as the CPU 31, are assumed to have the functions of the components of the image forming apparatus 10 and the image inspection apparatus 20 corresponding to each component. The inspection process may be interpreted in terms of each component of the image forming apparatus 30, for example, with the CPU 31 as the subject.

[0044] [effect] As described above, the image inspection device 20 has an inspection unit (CPU 21, image reading unit 27) that inspects an image formed on a recording medium based on a reference image used for inspecting the image formed on the recording medium, and a control unit (CPU 21) that executes a proof output mode in which a proof image corresponding to the reference image is formed on the recording medium, and the control unit determines whether or not execution of the proof output mode has been completed, and when it determines that execution of the proof output mode has been completed, executes an automatic inspection mode in which the inspection unit starts image inspection. This improves the productivity of image inspection.

[0045] In addition, the image inspection device 20 is equipped with a reading unit (image reading unit 27) that reads the proof image, and the control unit (CPU 21) determines that the execution of the proof output mode is completed when the reading unit registers the image read from the proof image as a reference image. This improves the productivity of image inspection.

[0046] Furthermore, the image inspection device 20 includes a setting section (operation display section 26) for setting the automatic inspection mode on / off, and the control section (CPU 21) executes the automatic inspection mode when the automatic inspection mode is set to on. Therefore, the setting can be made according to the user's request.

[0047] Furthermore, if the inspection unit detects an abnormality during image inspection, the control unit (CPU 21) does not execute the automatic inspection mode thereafter, and stops the job when it is determined that execution of the proof output mode has been completed. This makes it possible to prevent a test from being carried out despite the presence of an abnormality.

[0048] Furthermore, when the control unit (CPU 21) needs to set an inspection area, it does not execute the automatic inspection mode, and stops the job when it determines that execution of the proof output mode has been completed. Therefore, even if the automatic inspection mode is ON, if the inspection area needs to be set, it is possible to prevent the inspection area from not being set.

[0049] Furthermore, when the number of pages output for creating a reference image per copy in a job does not match the number of pages of the inspection output, the control unit (CPU 21) does not execute the automatic inspection mode and stops the job. Therefore, even if the automatic inspection mode is ON, if the inspection area setting is required, it is possible to prevent the inspection area from not being set.

[0050] In addition, the image forming device 30 has an image forming unit 37 that forms an image on a recording medium, an inspection unit (CPU 31, second image reading unit 311) that inspects the image formed on the recording medium based on a reference image used for inspecting the image formed on the recording medium, and a control unit (CPU 31) that executes a proof output mode in which the image forming unit forms a proof image corresponding to the reference image on the recording medium, and the control unit determines whether or not execution of the proof output mode has been completed, and when it determines that execution of the proof output mode has been completed, executes an automatic inspection mode in which the inspection unit starts image inspection. This improves the productivity of image inspection.

[0051] In addition, the image forming system 100 includes an image forming device 10 having an image forming unit 17 that forms an image on a recording medium, and an image inspection device 20 having an inspection unit (CPU 21, image reading unit 27) that inspects an image formed on the recording medium based on a reference image used for inspecting the image formed on the recording medium, and has a control unit (CPU 21) that executes a proof output mode for image formation in which a proof image corresponding to the reference image is formed on the recording medium, and the control unit determines whether execution of the proof output mode has been completed, and when it determines that execution of the proof output mode has been completed, executes an automatic inspection mode in which the inspection unit starts image inspection. This improves the productivity of image inspection.

[0052] In addition, the image inspection method is an image inspection method (inspection process) performed by an image forming system having an inspection unit that inspects an image formed on a recording medium based on a reference image used for inspecting the image formed on the recording medium, and a control unit that executes a proof output mode in which a proof image corresponding to the reference image is formed on the recording medium, and the control unit determines whether or not execution of the proof output mode has been completed, and when it determines that execution of the proof output mode has been completed, executes an automatic inspection mode in which the inspection unit starts image inspection. This improves the productivity of image inspection.

[0053] The program also causes a computer of an image inspection device having an inspection unit that inspects an image formed on a recording medium based on a reference image used for inspecting the image formed on the recording medium to function as a control unit that executes a proof output mode in which a proof image corresponding to the reference image is formed on the recording medium, and the control unit determines whether execution of the proof output mode has been completed, and when it determines that execution of the proof output mode has been completed, executes an automatic inspection mode in which the inspection unit starts image inspection. This improves the productivity of image inspection.

[0054] [others] The above-described embodiments are merely examples of the inspection device and image forming system according to the present invention, and the present invention is not limited to these. The detailed configurations and operations of the components constituting the device may be modified as appropriate without departing from the spirit of the present invention.

[0055] In addition, the CPU 21, ROM 22, RAM 23, memory unit 24, and operation display unit 26 of the above-mentioned image inspection device 20 may be shared with the CPU 11, ROM 12, RAM 13, memory unit 14, and operation display unit 19 of the image forming device 10, and the inspection processing may be performed using these shared configurations.

[0056] An information processing terminal such as an external personal computer may be connected to the image forming apparatus 10 or the image inspection apparatus 20, and the information processing terminal may perform the processing performed by the CPU 21 of the image inspection apparatus 20. Also, various cutting parameters may be inputted through an input interface such as a keyboard and a mouse provided on the information processing terminal such as a personal computer. In this case, a configuration including an information processing terminal such as a personal computer may be regarded as an image forming system.

[0057] Furthermore, in each of the above embodiments, a paper sheet P is used as the sheet, but the material of the sheet is not limited to paper, and may be sheet-shaped resin or the like. [Explanation of symbols]
