[0047] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0048] Figure 1 This is a diagram illustrating the image forming system 1 of this embodiment.

[0049] In the image forming system 1, an image forming apparatus 100 is provided, which performs image forming on paper, which is an example of a recording medium. Furthermore, the image forming system 1 includes a paper processing apparatus 200, which processes the paper on which the image has been formed by the image forming apparatus 100.

[0050] In this embodiment, the image forming system 1 outputs image data from the terminal device 2 containing a computer.

[0051] Furthermore, in this embodiment, the image forming system 1 performs image formation on paper based on the image data, and processes the paper on which the image is formed.

[0052] The image forming apparatus 100 includes an image forming unit 101 and an image forming control unit 103.

[0053] The image forming unit 101 can form a toner image corresponding to image data on paper, for example, using an electrophotographic method. Alternatively, the image forming unit 101 can also use other methods such as an inkjet head to form the image.

[0054] The image forming control unit 103 controls each part of the image forming apparatus 100.

[0055] Figure 2 This is a diagram showing the structure of the image forming control unit 103.

[0056] The image forming control unit 103 includes a central processing unit (CPU) 103A, a read-only memory (ROM) 103B, and a random access memory (RAM) 103C.

[0057] ROM 103B stores the program executed by CPU 103A. As an example of a processor, CPU 103A reads the program stored in ROM 103B and sets RAM 103C as the working area to execute the program.

[0058] Here, the program executed by the CPU 103A can be provided to the image forming control unit 103 in a state stored in a computer-readable recording medium such as a magnetic recording medium (magnetic tape, magnetic disk, etc.), an optical recording medium (optical disc, etc.), a magnetic-optical recording medium, or a semiconductor memory.

[0059] Furthermore, the program executed by the CPU 103A can also be downloaded to the image forming control unit 103 via communication methods such as the Internet.

[0060] In the example of a paper handling apparatus 200 (see reference 200), which is a recording medium handling apparatus, Figure 1 Inside the device, there are multiple paper handling units (not shown), a paper handling control unit 210, and an inspection device 220.

[0061] Each paper handling unit performs tasks such as perforation, binding, and folding of the paper. The paper handling control unit 210 controls each part of the paper handling apparatus 200. The inspection device 220 inspects the paper after it has been processed by the paper handling units.

[0062] Alternatively, the paper handling device 200 may not perform processes such as hole making, binding, or folding, but may only perform inspection using the inspection device 220.

[0063] In other words, in the paper handling apparatus 200, only the inspection device 220 can be used to inspect the paper transported from the image forming apparatus 100.

[0064] Figure 3 This is a diagram illustrating an example of the hardware structure of the paper handling control unit 210.

[0065] The paper handling control unit 210 includes a central processing unit (CPU) 210A, a read-only memory (ROM) 210B, and a random access memory (RAM) 210C.

[0066] ROM 210B stores the program executed by CPU 210A. As an example of a processor, CPU 210A reads the program stored in ROM 210B and executes the program using RAM 210C as the working area. The paper handling control unit 210 is a so-called computer.

[0067] In this embodiment, the CPU 210A executes the program stored in the ROM 210B, etc., thereby performing the processing described later.

[0068] Here, the program executed by the CPU 210A can be provided to the paper handling control unit 210 in a state stored in a computer-readable recording medium such as a magnetic recording medium (magnetic tape, disk, etc.), an optical recording medium (optical disc, etc.), a magnetic-optical recording medium, or a semiconductor memory.

[0069] Furthermore, the program executed by the CPU 210A can also be provided to the paper handling control unit 210 via communication methods such as the Internet.

[0070] In addition, in this embodiment, the term "processor" refers to a processor in a broad sense, including general-purpose processors (such as central processing units (CPUs)) or special-purpose processors (such as graphics processing units (GPUs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), programmable logic devices, etc.).

[0071] Furthermore, the actions of the processor can be performed not only by a single processor, but also collaboratively by multiple processors located in physically separate locations. Moreover, the order of the processor's actions is not limited to the order described in this embodiment and can be changed.

[0072] Figure 4 This diagram illustrates the functional units implemented by the CPU 210A of the paper handling control unit 210. Furthermore, the aforementioned... Figure 4 The text shows functional sections related to paper handling or inspection.

[0073] like Figure 4 As shown, the paper handling control unit 210 functions as the inspection result acquisition unit 221, the paper conveying control unit 222, and the information output unit 223.

[0074] As an example of an inspection result acquisition component, the inspection result acquisition unit 221 acquires the inspection device 220 (see reference). Figure 1 The result of each paper being inspected is the inspection result. In other words, the inspection result acquisition unit 221 acquires the information output from the inspection device 220.

[0075] The paper transport control unit 222 controls the driving of the transport member (described later) provided in the paper handling apparatus 200 to transport the paper. Thus, in this embodiment, the paper transported from the image forming apparatus 100 is transported within the paper handling apparatus 200.

[0076] In this embodiment, a conveying component for conveying paper, which is an example of a recording medium, is constituted by a paper conveying control unit 222 and a conveying member provided in the paper handling device 200.

[0077] If the inspection results for a specific type of paper (described later) do not meet the second condition, which is more lenient than the pre-defined conditions, the information output unit 223 outputs pre-defined information.

[0078] Here, the inspection result acquisition unit 221, the paper transport control unit 222, and the information output unit 223 are implemented by the CPU 210A of the paper handling control unit 210 executing the program stored in the ROM 210B, etc.

[0079] In this embodiment, the processes described below are performed by CPU 210A, which is an example of a processor. In other words, in this embodiment, CPU 210A, which is an example of a processor, executes a program stored in ROM 210B or the like, thereby performing the processes described below.

[0080] In other words, in this embodiment, the CPU 210A, as an example of a processor, executes a program stored in the ROM 210B, etc., thereby achieving... Figure 4 The functional units of the inspection result acquisition unit 221, paper transport control unit 222, and information output unit 223 shown are described below. Furthermore, in this embodiment, these functional units perform the processes described below.

[0081] Figure 5 This is a diagram illustrating the paper handling device 200.

[0082] In the paper handling apparatus 200 of this embodiment, a transport unit 231 is provided, which delivers paper from the image forming apparatus 100 to the downstream side. At the upper part of the transport unit 231, a paper feeding device 232 is provided for feeding paper into the transport unit 231.

[0083] Furthermore, the paper handling device 200 is provided with a folding unit 233, which folds the paper delivered from the transport unit 231 as needed.

[0084] Furthermore, on the downstream side of the folding unit 233, there is an inspection unit 234 for inspecting the paper.

[0085] Furthermore, although the illustration is omitted, the paper handling apparatus 200 is further equipped with a paper handling unit for performing hole-making, binding, and other processes.

[0086] Furthermore, the paper handling apparatus 200 is provided with a first paper path R1 through which paper from the image forming apparatus 100 passes. The first paper path R1 extends from the transport unit 231 to the first paper loading section 235 provided in the inspection unit 234.

[0087] In this embodiment, the first paper loading unit 235 loads the paper that has been transported through the first paper path R1.

[0088] Furthermore, in this embodiment, an inspection device 220 is provided in the inspection unit 234, which inspects the paper passing through the first paper path R1.

[0089] The inspection device 220 includes an image reading unit 226 and a determination unit 227 for reading images on paper passing through the inspection device 220, and performs inspections on the paper passing through the inspection device 220.

[0090] Here, the image reading unit 226 includes, for example, a so-called scanner device, which includes an imaging element such as a charge-coupled device (CCD). The determination unit 227 includes a computer device, which includes a CPU, for example, a processor.

[0091] Furthermore, in this embodiment, in the paper conveying direction of the first paper path R1, a second paper path R2 is provided downstream of the inspection device 220, branching off from the first paper path R1.

[0092] The second paper path R2 branches off from the first paper path R1 at branch 236 and extends to the second paper loading section 237. In this embodiment, the paper transported via the second paper path R2 is loaded at the second paper loading section 237.

[0093] Furthermore, in this embodiment, a confluence path R3 is provided, which extends from the paper feeding device 232 toward the first paper path R1 and converges at the confluence section 238 to the first paper path R1.

[0094] In this embodiment, in the paper conveying direction of the first paper path R1, the confluence unit 238 is located upstream of the inspection device 220. Paper supplied from the paper supply device 232 is supplied to the first paper path R1 via the confluence path R3, and then proceeds toward the first paper loading unit 235 or the second paper loading unit 237.

[0095] Furthermore, in this embodiment, a conveying roller 239 is provided as an example of a conveying component. The conveying roller 239 is respectively provided on the first paper path R1, the second paper path R2, and the confluence path R3, and conveys the paper located on these paths to the downstream side.

[0096] Furthermore, in the branch section 236, a switching member 241 is provided, which sets the destination of the paper that arrives at the branch section 236 through the first paper path R1 to either the first paper loading section 235 or the second paper loading section 237.

[0097] In this embodiment, the paper transport control unit 222 (see reference) Figure 4 The switching member 241 is driven to transport the paper that has reached the branch 236 via the first paper path R1 to either the first paper loading section 235 or the second paper loading section 237.

[0098] Here, refer to Figure 6 (A diagram illustrating the processing performed by the image forming system 1) will be used to explain the basic processing performed by the image forming system 1 of this embodiment.

[0099] In this embodiment, firstly, the image forming apparatus 100, as shown by symbol 6A, sequentially performs image forming on the paper. Furthermore, in this embodiment, the paper with the image formed by the image forming apparatus 100 is sequentially supplied to the paper processing apparatus 200, as shown by symbol 6B.

[0100] After being processed by the paper handling device 200, or after simply passing through the paper handling device 200, the paper is conveyed to the inspection device 220 located in the inspection unit 234.

[0101] Furthermore, the inspection device 220 performs checks for the presence or absence of dirt. The check for the presence or absence of dirt can be performed using known methods.

[0102] Specifically, in this embodiment, the determination unit 227 of the inspection device 220 (refer to...) Figure 5 For example, a pre-registered reference image, and an image reading unit 226 passing through the inspection device 220 (see reference). Figure 5 The images obtained by reading the actual paper are compared. Furthermore, the presence or absence of dirt is determined based on the comparison results.

[0103] In this embodiment, whenever the inspection device 220 inspects the paper, the inspection result (the determination result obtained by the determination unit 227) of each paper is output from the inspection device 220 to the inspection result acquisition unit 221, which is an example of an inspection result acquisition unit (see reference 221). Figure 4 Furthermore, the inspection result acquisition unit 221 acquires the inspection result.

[0104] Furthermore, the paper transport control unit 222 (see reference) Figure 4 Based on the inspection results obtained by the inspection result acquisition unit 221, the paper (the paper that has passed through the inspection device 220) is transported to a predetermined transport destination.

[0105] Specifically, when the inspection result of the paper to be inspected, obtained by the inspection result acquisition unit 221, meets the predetermined conditions, the paper transport control unit 222 transports the paper to the first paper loading unit 235 (see reference 221), which is an example of a transport destination. Figure 6 The symbol 6X).

[0106] Furthermore, if the inspection result of the paper to be transported does not meet the predetermined conditions, the paper transport control unit 222 will transport the paper to the second paper loading unit 237 (see reference 237), which is another transport destination. Figure 6 The symbol 6Y).

[0107] Therefore, in this embodiment, when the processing of a printing job is completed, such as Figure 6 As indicated by symbol 6D, paper is loaded in either the first paper loading section 235 or the second paper loading section 237.

[0108] Subsequently, in this embodiment, if the second paper loading section 237 is loaded with paper, the paper loaded in the second paper loading section 237 is discarded.

[0109] Moreover, at this time, the paper loaded in the first paper loading section 235, which meets the predetermined conditions, is placed in the paper feeding device 232 by the operator as shown by symbol 6E.

[0110] In this embodiment, if a portion of the paper has dirt or other contaminants and that portion of the paper is loaded into the second paper loading section 237 (refer to symbol 6Y), that portion of the paper is discarded.

[0111] Furthermore, the paper (refer to symbol 6X) loaded in the first paper loading section 235 and meeting the predetermined conditions is placed in the paper feeding device 232 by the operator as shown by symbol 6E.

[0112] Specifically, this example illustrates the following situation: as indicated by symbol 6Y, dirt exists on the third and sixth sheets of paper, and the inspection results of the third and sixth sheets do not meet the predetermined conditions. In this case, the third and sixth sheets of paper are transferred to the second paper loading unit 237. Furthermore, the third and sixth sheets of paper are discarded at this time.

[0113] On the other hand, the first, second, fourth, and fifth sheets of paper (the sheets indicated by symbol 6X) that meet the predetermined conditions and are loaded in the first paper loading section 235 are placed in the paper feeding device 232 by the operator as indicated by symbol 6E.

[0114] Then, it was reprinted.

[0115] During reprinting, the image forming apparatus 100 is used to print images formed on the aforementioned portions of paper (the third and sixth sheets) onto new paper, and the printed new paper is fed into the first paper path R1 (refer to...). Figure 5 ).

[0116] Furthermore, the paper (first sheet, second sheet, fourth sheet, and fifth sheet) that meet the predetermined conditions are fed from the paper feeding device 232 into the first paper path R1.

[0117] Furthermore, these papers, once again fed into the first paper path R1, pass through the inspection device 220 (see reference). Figure 6 After the symbol 6G is added, it is transferred to either the first paper loading unit 235 or the second paper loading unit 237.

[0118] Furthermore, when the state is such that no paper is loaded in the second paper loading section 237, but all the paper is loaded in the first paper loading section 235 as indicated by symbol 6K, the processing in the image forming system 1 ends.

[0119] Subsequently, in the aforementioned processing example, the paper loaded in the first paper loading unit 235 is sent to a subsequent process. Furthermore, in the subsequent process, a predetermined article is manufactured from the paper.

[0120] Specifically, a booklet is cited as an example of a product. Specifically, one or more booklets are produced based on the paper that is transported to the first paper loading section 235, through binding processes using binding needles or without binding needles.

[0121] Here, "booklet" refers to multiple sheets of paper that have been bound together. "Binding" is not limited to binding with staples, but includes binding where the papers are pressed together without staples or binding with clips or other binding devices.

[0122] Furthermore, the “article” manufactured from the paper loaded in the first paper loading section 235 is not limited to booklets.

[0123] As a product, any product can be made from a recording medium such as paper. Products such as newspapers that have been folded, products such as notebooks that have been bundled with paper, handicrafts made of paper, or postcards or business cards are all equivalent to "products".

[0124] Moreover, the term "products" is not limited to products sold externally, but also includes products that circulate within an organization in forms other than those sold externally.

[0125] Furthermore, in the paper handling apparatus 200, paper that is not included in the article and is removed before the article is completed is sometimes conveyed.

[0126] In other words, in this embodiment, sometimes paper that is not used as a final product and is not included in the final product is transported to the inspection device 220 and then to the first paper loading unit 235 or the second paper loading unit 237.

[0127] Here, regarding paper not included in the final product, since it is not provided to customers of the final product, strict inspection is not required, nor is reprinting necessary. In other words, regarding paper not included in the final product, it can basically be used directly even if it becomes soiled.

[0128] However, in the process described above, if the paper, which is not included in the final product, becomes soiled or otherwise damaged, the paper will be transferred to the second paper loading unit 237 for reprinting.

[0129] At this point, the operator's workload increases. Moreover, the reprinting process can easily lead to delays in the image forming system 1 or in subsequent processes.

[0130] Furthermore, the following scenario is also considered: when paper not included in the final product is transported to the second paper loading unit 237, the operator visually confirms each piece of paper transported to the second paper loading unit 237 and then selects the paper that can be reused.

[0131] However, at this point, the operator's screening requires physical labor, increasing their workload. Consequently, this can easily lead to delays in the processing of the image forming system 1 or in subsequent processes.

[0132] Therefore, in this embodiment, the specific paper (hereinafter referred to as "specific paper") that is not included in the product and can be used directly even if it is soiled is not transported to the second paper loading unit 237, but to the first paper loading unit 235.

[0133] In other words, in this embodiment, even if the inspection result obtained by the inspection result acquisition unit 221 for a specific paper does not meet the predetermined conditions, the paper handling control unit 210 still transports the specific paper to the first paper loading unit 235.

[0134] Regarding specific sheets of paper, they will eventually be removed. Therefore, even if, as in this embodiment, specific sheets of paper whose inspection results do not meet the predetermined conditions are transported to the first paper loading unit 235, these specific sheets of paper will not ultimately be included in the article, and thus no problem will arise.

[0135] On the other hand, in this embodiment, the paper conveying control unit 222 conveys paper that does not conform to a specific paper type and will be included in the article to the second paper loading unit 237, which is another conveying destination, if the predetermined conditions are not met.

[0136] Here, specific types of paper are listed below, for example.

[0137] (1) Paper printed with printing-related information such as the name of the printing job or printing conditions.

[0138] (2) When using inkjet printing as the image forming unit 101, the paper used for refreshing (the paper for ejecting ink) or the paper used for nozzle inspection.

[0139] (3) Papers placed in the printing room for separation

[0140] Figure 7 It is a flowchart illustrating a series of processes performed by the image forming system 1 of this embodiment.

[0141] In this embodiment, firstly, the operator uses a terminal device 2 (not shown) (see reference 2). Figure 1 The terminal device 2 performs printing instructions (step S101), and simultaneously outputs image data to the image forming system 1.

[0142] In the image forming system 1, the image forming apparatus 100 sequentially prints paper based on the image data, and then transfers the paper to the paper processing apparatus 200 for inspection of each sheet.

[0143] Specifically, in this embodiment, whenever paper passes through the inspection device 220, the inspection device 220 is used to inspect and determine whether the paper to be inspected meets the predetermined conditions (step S102).

[0144] Furthermore, for papers whose inspection results obtained by the inspection device 220 are that they meet the predetermined conditions, they are transported to the first paper loading unit 235 (step S103).

[0145] On the other hand, for paper whose inspection result obtained by the inspection device 220 does not meet the pre-defined conditions, it is determined whether it conforms to a specific paper (step S104).

[0146] Furthermore, if it is determined in step S104 that the paper conforms to a specific type of paper, the paper that is determined to conform to the specific type of paper is transported to the first paper loading unit 235 (step S105).

[0147] On the other hand, for papers that are not determined to be compatible with a specific type of paper in step S104, they are transferred to the second paper loading unit 237 (step S106).

[0148] Then, it is determined whether printing of all pages contained in the printing operation has been completed (step S107). If it is determined that printing has been completed, the process ends. On the other hand, if it is not determined that printing has been completed in step S107, the process after step S102 is repeated.

[0149] Figure 8 (A) and Figure 8 (B) is a diagram showing a specific example of the processing performed on a particular type of paper.

[0150] The paper conveying control unit 222 of this embodiment (see reference) Figure 4 Based on information obtained from each sheet of paper sequentially conveyed in the paper handling apparatus 200, a specific sheet of paper is identified. Furthermore, the paper conveying control unit 222 conveys the identified specific sheet of paper to a first paper loading unit 235, which is an example of a conveying destination.

[0151] More specifically, the paper conveying control unit 222 grasps a specific paper based on a read image obtained by reading images formed on each paper sequentially conveyed in the paper handling apparatus 200, and conveys the grasped specific paper to the first paper loading unit 235.

[0152] More specifically, the paper transport control unit 222 determines, based on the read images obtained by reading the images formed on each sheet, which indicate that the similarity to a pre-defined threshold of a registered image exceeds a pre-defined threshold.

[0153] Furthermore, the paper transport control unit 222 grasps the determined paper as a specific paper and transports the grasped specific paper to the first paper loading unit 235.

[0154] In the processing example, such as Figure 8 As indicated by the symbol 8A of (A), in the inspection device 220 (refer to) Figure 8 The memory (not shown) of (A) contains a pre-registered image to be formed on a sheet of paper conforming to a specific type of paper.

[0155] In other words, in the aforementioned processing example, as preparation for printing, a predetermined image to be formed on a specific type of paper is pre-registered in the inspection device 220. Hereinafter, this image will be referred to as the "registered image".

[0156] Moreover, in the aforementioned processing example, in Figure 8 During printing as shown in (B), the paper passes sequentially through the inspection device 220. At this time, the image reading unit 226 provided in the inspection device 220 (see reference) is used. Figure 5It reads the images formed on the papers that pass through the inspection device 220 in sequence.

[0157] Thus, a reading image is generated for each sheet of paper.

[0158] Furthermore, in the inspection device 220, whenever a new read image is generated, the similarity between the read image and the registered image is determined.

[0159] Furthermore, when a piece of paper has a similarity exceeding a predetermined threshold between the read image and the registered image, the inspection device 220 outputs information about the paper, and the inspection result acquisition unit 221 (refer to...) Figure 4 To obtain information about the paper.

[0160] Next, the paper transport control unit 222, based on the information about the paper output from the inspection result acquisition unit 221, identifies the paper determined by the information about the paper as a specific paper and transports the specific paper to the first paper loading unit 235.

[0161] Here, the paper transport control unit 222, even if the paper is held as a specific type of paper, Figure 8 (A) and Figure 8 As indicated by the symbol 8X of (B), the paper is still conveyed to the first paper loading section 235 despite the presence of dirt.

[0162] In other words, the paper handling control unit 210 will still transport the paper that is held as a specific type of paper to the first paper loading unit 235 even if the inspection device 220 determines that the paper does not meet the pre-defined conditions.

[0163] In addition, the paper handling control unit 210 also transports specific papers that are determined by the inspection device 220 to meet the pre-defined conditions to the first paper loading unit 235.

[0164] Figure 9 This is a diagram illustrating another processing example.

[0165] In the processing example, the paper transport control unit 222 determines the paper on which a predetermined specific image is formed based on the reading image obtained by the inspection device 220.

[0166] Furthermore, the paper transport control unit 222 grasps the determined paper as a specific paper and transports the specific paper to the first paper loading unit 235.

[0167] In the processing example, as shown by symbol 9A, a pre-defined specific image 400 is formed on a portion of a sheet of paper conforming to a specific type of paper.

[0168] Here, in the processing example, the specific image 400 is a star-shaped image, but it can also be an image other than a star. Specifically, it can also be an image with a rectangular, elliptical, or circular shape. Furthermore, the specific image 400 can also contain text information.

[0169] The paper transport control unit 222 transports a portion of a sheet of paper with a predetermined specific image 400 to the first paper loading unit 235. In other words, the paper transport control unit 222 grasps the sheet with the predetermined specific image 400 as a specific sheet of paper and transports it to the first paper loading unit 235.

[0170] More specifically, similarly, the paper transport control unit 222 transports paper with a predetermined specific image 400 to the first paper loading unit 235, even if the paper is dirty and does not meet the predetermined conditions.

[0171] Here, in the processing example, for the original image data 9B that becomes the source of the image formed on the paper that is a specific type of paper, there is pre-attached image data 9C for forming the specific image 400.

[0172] More specifically, in the processing example, in the terminal device 2, the source image data 9B is pre-attached with forming image data 9C for forming the specific image 400.

[0173] Therefore, in this embodiment, when an image is formed on a piece of paper conforming to a specific type of paper using the image forming apparatus 100, a specific image 400 will be included in a portion of the image.

[0174] Furthermore, in the processing example, the specific image 400 is pre-registered in the inspection device 220.

[0175] Furthermore, in the processing example, when the inspection device 220 obtains a reading image of each paper, the inspection device 220 determines whether the reading image contains the registered specific image 400.

[0176] Furthermore, when the inspection device 220 determines that the read image contains the specific image 400, it outputs information indicating that the specific image 400 is present, and the inspection result acquisition unit 221 (see reference) Figure 4 ) Obtain the information containing the intent of a specific image 400.

[0177] Furthermore, when the inspection result acquisition unit 221 acquires information containing the intent of a specific image 400, the paper transport control unit 222 grasps the paper containing the specific image 400 in the read image as a specific paper. Then, the paper transport control unit 222 transports the grasped specific paper to the first paper loading unit 235.

[0178] More specifically, similarly, even if a particular sheet of paper is found to be dirty and does not meet the pre-defined conditions by the inspection device 220 as indicated by symbol 9E, the paper transport control unit 222 will still transport the particular sheet of paper to the first paper loading unit 235.

[0179] Figure 10 This is a diagram representing another processing example.

[0180] In the processing example, the paper conveying control unit 222 grasps a specific sheet of paper based on information attached to image data that becomes the source of the image formed on the paper, and conveys the grasped specific sheet of paper to the first paper loading unit 235.

[0181] More specifically, in the processing example, for image data input to the image forming system 1 that is the source of an image formed on a specific type of paper, an association indicating that the paper used to form the image based on the image data is a specific type of paper is pre-attached. Furthermore, this additional association is performed, for example, in the terminal device 2.

[0182] More specifically, in the processing example, for image data that is the source of an image formed on a specific type of paper, additional attribute information indicating that the paper from which the image is formed is a specific type of paper is added.

[0183] Furthermore, in the aforementioned processing example, when the paper is sequentially transported by the paper handling device 200, the paper transport control unit 222 grasps the paper with an image formed based on image data containing attribute information representing a specific type of paper as a specific type of paper.

[0184] Furthermore, the paper transport control unit 222 transports the specific paper it holds to the first paper loading unit 235.

[0185] More specifically, the paper transport control unit 222 transports the paper with an image formed based on image data containing attribute information representing a specific type of paper to the first paper loading unit 235 even if there is dirt as shown by symbol 10E.

[0186] In other words, the paper transport control unit 222 transports the paper with an image formed based on image data containing attribute information representing a specific type of paper to the first paper loading unit 235 even if the predetermined conditions are not met.

[0187] Figure 11 This is a diagram representing another processing example.

[0188] In the processing example, the "image data is associated with information" is pre-loaded with information about the order in which a particular sheet of paper is transported by the paper handling device 200.

[0189] In other words, in the processing example, the attribute information attached to the image data includes information about the order in which a particular sheet of paper is transported by the paper handling device 200.

[0190] In other words, in the processing example, the image data input to the image forming system 1 is associated with information about the order in which a particular sheet of paper is conveyed by the paper handling device 200.

[0191] Furthermore, in the aforementioned processing example, the paper conveying control unit 222 grasps a specific sheet of paper based on information about the sequence, and conveys the grasped specific sheet of paper to the first paper loading unit 235.

[0192] In this embodiment, the paper conveying control unit 222 sequentially conveys each sheet of paper that has been inspected by the inspection device 220 to either the first paper loading unit 235 or the second paper loading unit 237.

[0193] During the paper transport control unit 222, the paper transported in the order determined by the information about the order is regarded as a specific paper and transported to the first paper loading unit 235.

[0194] More specifically, in the processing example, the paper conveying control unit 222 conveys the paper to the first paper loading unit 235 even if it is dirty and does not meet the predetermined conditions as shown by symbol 11E.

[0195] In this embodiment, the image data that will become the source of the image formed on the paper is such as... Figure 11 As indicated by symbol 11A, the image is input from the terminal device 2 to the image forming system 1, thereby initiating the printing process performed by the image forming apparatus 100 and the processing in the paper handling apparatus 200.

[0196] In this embodiment, the image data input to the image forming system 1 is pre-attached with information about the order in which specific sheets of paper are transported.

[0197] Here, "information about order" can be defined as information about order itself, or, for example, as... Figure 11 The symbol 11B is shown as information indicating which page is a specific sheet of paper.

[0198] In other words, as "information about order," it can also be set as the page number of a specific type of paper.

[0199] (other)

[0200] In addition, in this embodiment, a second condition is set that is more lenient than the pre-defined condition.

[0201] The inspection device 220 also determines whether a specific piece of paper meets the second condition, and the inspection result acquisition unit 221 also acquires the result of the determination.

[0202] Furthermore, in this embodiment, if the result obtained by the inspection result acquisition unit 221 is that the second condition is not met, the information output unit 223 outputs pre-defined information such as information indicating that a problem has occurred in the paper handling device 200.

[0203] Here, if the inspection results for a particular piece of paper do not meet the second condition, which is more lenient than the pre-defined conditions, there is not only the problem of soiling the paper, but also the problem of creating a device that significantly disrupts the image formed on the paper.

[0204] Therefore, in this embodiment, as described above, if the inspection result for a specific piece of paper is that the second condition is not met, the information output unit 223 outputs pre-defined information such as information indicating that a problem has occurred in the paper handling device 200.

[0205] Furthermore, in this embodiment, error notifications are sent to the user, for example, via a display device (not shown) provided in the image forming system 1 or a display device (not shown) provided in the terminal device 2.

[0206] Here, the so-called "pre-defined conditions" refers to, for example, the state in which the similarity between the reference image and the reading image obtained by reading the physical paper using the image reading unit 226 of the inspection device 220 is greater than a pre-defined first threshold.

[0207] Moreover, the so-called failure to meet the "pre-defined conditions" refers to the state where the approximation degree is less than the first threshold.

[0208] Moreover, the so-called failure to meet the "second condition that is more lenient than the pre-defined condition" refers to, for example, the following state: the approximation between the reference image and the reading image obtained by reading the physical paper using the image reading unit 226 is less than a second threshold that is less than the first threshold.

[0209] Moreover, the so-called "satisfying the second condition which is more lenient than the pre-defined conditions" refers to a state in which the approximation is greater than the second threshold.
