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, first, an image of a character string is formed on a sheet of paper by an image forming apparatus. Next, the character string is read for each page by an image inspection device connected to the image forming apparatus. Then, a real-time collation job is executed to compare (collate) the character string with collation information in a collation information management table (Patent Document 1). Here, the collation information management table is a table that manages collation information in page order.

[0003] In such real-time collation, first, the collation information corresponding to the first page of the collation information management table is compared with the character string read from the paper on which the image is formed, and then the comparison is performed in page order.

[0004] [Patent Document 1] JP 2009-157869 A Summary of the Invention [Problem to be solved by the invention]

[0005] At a site where an image forming apparatus is used, a job may be temporarily cancelled due to a mechanical trouble during image formation, and image formation may resume from the Nth page of the real-time collation job that was forming images when the trouble occurred. Also, for example, in a real-time collation job of 100,000 pages, it may be desired to divide the job into jobs for forming images of 10,000 pages each. In the above case, the image inspection device recognizes the first page of the job as page 1, so there are cases where the page number in the matching information management table does not match the page number of the paper on which the image is formed, resulting in a matching error. For example, consider the case where images are formed for 10,000 pages each (JOB1=pages 1 to 10,000, JOB2=pages 10,001 to 20,000) as shown in Fig. 14 using the verification information management table for 20,000 pages in Fig. 13. In this case, since the page number of the paper on which the image is formed matches the page number in the verification information management table in JOB1, "00001" is verified against "00001" and verification is successful. However, since the page number of the paper on which the image is formed does not match the page number in the verification information management table in JOB2, "10001" is verified against "00001", and a verification error occurs in JOB2.

[0006] An object of the present invention is to enable matching to be performed from any page. [Means for solving the problem]

[0007] In order to solve the above problems, the image inspection device according to the present invention comprises: A reading unit that reads management information formed on the paper; a determination unit that determines whether the management information and the collation information match by using a collation information management table that manages the page number and the collation information for each page number of a sheet; A setting unit that sets a start page number for starting the determination; having The determination unit starts the determination from the starting page number.

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 an external information processing terminal such as a PC (Personal Computer) 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 storage unit 14, a paper feed unit 15, an image reading unit 16, an image forming unit 17, 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 set paper feed trays 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 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.

[0023] The communication I / F 110 is composed of a NIC (Network Interface Card), a modem, and the like, and transmits and receives data to and from the image inspection device 20, a PC (Personal Computer), and the like.

[0024] [Image inspection equipment] The image inspection device 20 reads the management information imaged within a specified area on the paper P for each page, obtains the matching information corresponding to that page number in real time from a matching information management table that manages matching information for each page number, and inspects the paper P by comparing (matching) the management information with the matching information (real-time matching processing). The management information and the collation information are, for example, numbers, character strings, symbols, and the like. 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.

[0025] 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 functions as a determination unit that determines whether the management information and the collation information match, using a collation information management table that manages the page number and the collation information for each page number of a sheet. The CPU 21 functions as a setting unit that sets the start page number at which the determination starts. The CPU 21 may set start management information or start collation information at which the determination starts.

[0026] The storage unit 24 is configured with a HDD, a non-volatile semiconductor memory, or the like, and stores various data such as a collation information management table.

[0027] 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.

[0028] 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.

[0029] The communication I / F 28 is composed of a NIC, a modem, and the like, and transmits and receives data between the image forming apparatus 10 and a PC, and the like.

[0030] The image reading unit 27 reads the paper P carried in from the image forming apparatus 10 and generates image data. The image reading unit 27 can read both sides of the paper P. Specifically, the image reading unit 27 reads light that is irradiated from a light source and reflected by the document using a CCD (Charge Coupled Device) image sensor or the like. The image reading section 27 functions as a reading section that reads the management information formed on the paper. 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.

[0031] [Case 1: Real-time matching process] The flow of the real-time collation process executed by the CPU 21 will be described with reference to Fig. 3. The real-time collation process is started, for example, when the CPU 21 acquires job information. In parallel, the image forming apparatus 10 forms an image of management information in a predetermined area on the paper P for each page. It is assumed that the collation information management table (FIGS. 5 and 6) used in the real-time collation process has already been transmitted to image inspection device 20 from an information processing terminal such as an external PC.

[0032] First, when the CPU 21 receives job information, it determines whether the job information is information about a real-time collation job (step S1). If the job information is information related to a real-time collation job (step S1; YES), the CPU 21 advances the real-time collation process to step S2. If the job information is not information related to a real-time collation job (step S1; NO), the CPU 21 ends the real-time collation process.

[0033] Next, the CPU 21 determines whether or not a start page number for real-time verification processing has been set (step S2). If the start page number of the real-time verification process is set (step S2; YES), the CPU 21 obtains the start page number and advances the real-time verification process to step S3. If the start page number of the real-time verification process is not set (step S2; NO), the CPU 21 advances the real-time verification process to step S5.

[0034] Here, a method for setting the start page number will be described. The start page number may be set from an external information processing terminal such as a PC, from the image inspection device 20, or added to the collation information management table. When real-time collation is performed, the start page number is set before the real-time collation job (at the latest before step S2).

[0035] The cases where the start page number is set from an external information processing terminal such as a PC, and where it is set from image inspection device 20 will be described. The user inputs a start page number (N) from a start page number setting screen D1 shown in Fig. 4, which is displayed on the display unit of an external information processing terminal such as a PC or on the operation display unit 26 of the image inspection device 20. The CPU 21 acquires the input start page number. The start page number setting screen D1 shown in FIG. 4 provides an interface for directly inputting the start page number, but various interfaces are possible, such as allowing the user to select the page number from a pull-down menu.

[0036] A case where the verification information is added to the management table will be described. 6, the verification information management table itself is accompanied by a start page number (N) and transmitted from an external information processing terminal such as a PC to image inspection device 20. CPU 21 obtains the start page number from the verification information management table.

[0037] Returning to the explanation of the real-time matching process. Next, the CPU 21 searches for the start page number (N) from the page numbers in the collation information management table (FIGS. 5 and 6) (step S3). Next, CPU 21 acquires the collation information (M) corresponding to the page number that matches the start page number (N) from the collation information management table (FIGS. 5 and 6) (step S4).

[0038] The image inspection device 20 acquires the collation information (1001) corresponding to the page number (1) in the collation information management table (FIGS. 5 and 6) (step S5).

[0039] Next, the CPU 21 causes the image reading unit 27 to read the conveyed paper P, and reads the management information from a predetermined area on the paper P (step S6). The CPU 21 obtains the management information from the image reading unit 27.

[0040] Next, the CPU 21 determines whether the collation information acquired in step S4 or step S5 matches the management information acquired in step S6 (step S7). If they match (step S7; YES), the CPU 21 advances the real-time collation process to step S9. If they do not match (step S7; NO), the CPU 21 advances the real-time collation process to step S8. If there is an abnormality in the reading by the image reading unit 27 in step S6 and the CPU 21 cannot acquire the management information, it determines that there is no match (step S7; NO). For example, there may be a problem with the management information imaged in a predetermined area on the paper P by the image forming apparatus 10. Possible problems include when there is a gap or smudge in the management information, when the management information has been imaged outside the predetermined area on the paper P, and so on.

[0041] Next, the CPU 21 displays an error on the operation display unit 26 (step S8).

[0042] Next, the CPU 21 determines whether or not it is the last sheet (step S9). If it is not the last sheet (step S9; NO), the CPU 21 advances the real-time collation process to step S10. If it is the last sheet (step S9; YES), the CPU 21 ends the real-time collation process.

[0043] Next, the CPU 21 obtains the collation information corresponding to the next page number in the collation information management table (step S10). After obtaining the information, the CPU 21 advances the real-time collation process to step S6, and reads the management information of the next sheet of paper that has been conveyed after image formation.

[0044] In this way, when a job is interrupted, deleted, and restarted from the middle of the job, or when a job is divided and executed as multiple jobs, the start page number can be set before the start of each job as the page number at which real-time matching is restarted, thereby reducing the work of recreating and resending the matching information management table. Specifically, this will be explained using the image diagram of the real-time collation job shown in Figure 7. JOB1 is the first job to be executed. JOB2 is the job to be executed when restarting. Before the start of JOB2, the starting page number (N) is set, so the page number of the first page of JOB2 becomes N.

[0045] In case 1, since the next page number is searched for in step S10, the paper P needs to be transported in the correct order.

[0046] In addition, since the matching information management table is searched using the page number as a key, the sets of page numbers and matching information do not need to be arranged in the order of page numbers. For example, the sets of page numbers and matching information may be arranged in descending order of page numbers as shown in FIG. 8, or may be arranged in a random order.

[0047] In the above, the start page number is set in step S2, but management information (start management information) or collation information (start collation information) at which the determination starts may be set. When the start management information or start collation information is set, the page number corresponding to the start management information or start collation information is searched for in the collation information management table and obtained as the start page number.

[0048] [Case 2: Real-time matching process] In case 1, the starting page number is set based on a user operation, but in case 2, the original page number included in the job information is used as the starting page number. 9, a flow of the real-time verification process executed by the CPU 21 will be described. The processes other than step S22 and step S27 described below are the same as those in case 1, except that the start page number is replaced with the document page number.

[0049] The CPU 21 obtains the document page number included in the job information, and searches for the document page number (N) from the page numbers in the verification information management table (step S22).

[0050] The CPU 21 determines whether it is the last sheet (step S27). If it is not the last sheet (step S27; NO), the CPU 21 advances the real-time collation process to step S22. If it is the last sheet (step S27; YES), the CPU 21 ends the real-time collation process.

[0051] In this way, when a job is interrupted, deleted, and then restarted from the middle of the job, or when a job is divided and executed as multiple jobs, the original page number included in the job information at the time of restarting automatically becomes the starting page number, thereby reducing the work of recreating and resending the collation information management table.

[0052] Furthermore, the sheets P do not need to be transported in the correct order, and there is no need to be aware of the order in which the sheets P are transported.

[0053] [Case 3: Real-time matching process] In case 3, if the management information read from the first sheet P conveyed is included in the collation information on the collation information management table, the page number corresponding to the collation information is used as the starting page number. 10, a flow of the real-time collation process executed by the CPU 21 will be described. The processes other than steps S32 to S37 described below are the same as those in case 1.

[0054] The CPU 21 causes the image reading unit 27 to read the conveyed paper P, and to read the management information from a predetermined area on the paper P (step S32). The CPU 21 obtains the management information (M) from the image reading unit 27.

[0055] Next, the CPU 21 searches for management information (M) from the collation information in the collation information management table (FIGS. 5 and 6) (step S33).

[0056] Next, when the CPU 21 finds in step S33 that there is collation information that matches the management information (M), the CPU 21 advances the real-time collation process to step S35 (step S34; YES). When it is found in step S33 that there is no matching collation information that matches the management information (M), the CPU 21 advances the real-time collation process to step S42 (step S34; NO).

[0057] Next, the CPU 21 acquires the page number (N) corresponding to the collation information that matches the management information (M) from the collation information management table (FIGS. 5 and 6) (step S35).

[0058] Next, the CPU 21 causes a display unit such as the operation display unit 26 to display a warning of the page number (N) and the verification information (M), and advances the real-time verification process to step S37 (step S36). In addition to the above, the CPU 21 may temporarily suspend the real-time matching process and display a pop-up for confirming with the user whether to continue the real-time matching process on the operation display unit 26. In this case, when the user inputs an instruction to continue the process in the pop-up, the CPU 21 continues the real-time matching process. Furthermore, when a job is interrupted and then resumed without being deleted, step S36 does not need to be executed because the job is restarted from the page of paper P next to the page of paper P for which collation has already been completed. An example of a case where a job is interrupted and then resumed without being deleted is when the job is interrupted due to a paper outage or a paper jam.

[0059] Next, the CPU 21 determines whether or not it is the last sheet (step S37). If it is not the last sheet (step S37; NO), the CPU 21 advances the real-time collation process to step S38. If it is the last sheet (step S37; YES), the CPU 21 ends the real-time collation process.

[0060] In this way, when a job is interrupted, deleted, and then restarted from the middle of the job, or when a job is divided and executed as multiple jobs, the page number searched based on the management information read from the first sheet P conveyed at the time of restarting becomes the starting page number automatically, thereby reducing the work of recreating and retransmitting the collation information management table.
