[0001] The present invention relates to an information processing apparatus, an image forming apparatus, and a method for classifying document images, and more particularly to a technique for saving document images in a specified save destination. [Background technology]

[0002] In an image forming device, an image of a document is read by an image reading unit, and the image of the document is then formed on recording paper by an image forming unit, or the read image of the document is transmitted. However, when images of many documents are read and these document images are to be classified, this classification task becomes cumbersome for the user.

[0003] In the electronic document file processing method described in Patent Document 1, when a document created on a client PC is printed, when a document is sent or received by email, or when a document is read by a scanner, a unique identification code is added to the document, and the document with the identification code added is transferred to and registered in a document registration server, and when searching for a document registered in the document registration server to use or reprocess the document, the identification code added to the document is entered to obtain the desired document. This makes document searching easy. [Prior art documents] [Patent documents]

[0013] Hereinafter, an information processing device, an image forming device, and a method for classifying document images according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing an image forming device according to an embodiment of the present invention. The image forming device 10 is an example of an information processing device according to the present invention. The image forming device 10 is an MFP (multi-function peripheral) that combines multiple functions such as a copy function and a printer function. The image forming device 10 includes an image reading unit 11 and an image forming unit 12.

[0014] The image reading unit 11 has an imaging unit (such as a CCD) equipped with an imaging element that optically reads an image of a document, and image data (document image) showing an image of the document is generated by this imaging element. The image reading unit 11 has an automatic document feeder (ADF: automatic document feeder). The automatic document feeder transports multiple documents placed on the document placement table 1 in succession to the imaging unit for each document, and the imaging unit reads each document.

[0015] The image forming section 12 forms an image represented by the image data on a recording sheet, and includes an image forming unit 3M for magenta, an image forming unit 3C for cyan, an image forming unit 3Y for yellow, and an image forming unit 3Bk for black. In each of the image forming units 3M, 3C, 3Y, and 3Bk, the surface of the photosensitive drum 4 is uniformly charged, the surface of the photosensitive drum 4 is exposed to light, an electrostatic latent image is formed on the surface of the photosensitive drum 4, the electrostatic latent image on the surface of the photosensitive drum 4 is developed into a toner image, and the toner image on the surface of the photosensitive drum 4 is primarily transferred to the intermediate transfer belt 5. As a result, a color toner image is formed on the intermediate transfer belt 5. This color toner image is secondarily transferred to the recording sheet P conveyed from the paper feed section 14 through the conveying path 8 in the nip area N between the intermediate transfer belt 5 and the secondary transfer roller 6.

[0016] Thereafter, the recording paper P is heated and pressed by the fixing device 15, the toner image on the recording paper P is fixed by thermocompression, and the recording paper P is then discharged onto a discharge tray 19 via discharge rollers 7.

[0017] Next, a configuration relating to the control of the image forming apparatus 10 will be described. Fig. 2 is a functional block diagram showing the main internal configuration of the image forming apparatus 10. As shown in Fig. 2, the image forming apparatus 10 includes an image reading section 11, an image forming section 12, a display section 21, an operation section 22, a touch panel 23, a network communication section (NW communication section) 24, a facsimile communication section (FAX communication section) 25, an image memory 26, a storage section 27, a code reader 28, and a control unit 29. These components are capable of transmitting and receiving data or signals to and from each other via a bus.

[0018] The display unit 21 is configured with a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display.

[0019] The operation unit 22 includes physical keys such as a numeric keypad, a decision key, and a start key.

[0020] A touch panel 23 is disposed on the screen of the display unit 21. The touch panel 23 is a so-called resistive film type or capacitive type touch panel, which detects contact (touch) of a user's finger or the like with the touch panel 23 together with the contact position, and outputs a detection signal indicating the coordinates of the contact position to a control unit 31 (to be described later) of the control unit 29. This makes it possible to operate a GUI (Graphical User Interface) and the like displayed on the screen of the display unit 21 through the touch panel 23.

[0021] The network communication unit (NW communication unit) 24 is a communication interface including a communication module such as a LAN chip (not shown), and is connected to other terminal devices via a wired or wireless LAN to transmit and receive data to and from the other terminal devices.

[0022] A facsimile communication unit (FAX communication unit) 25 transmits and receives image data representing an image to and from other image forming apparatuses, facsimile machines, and the like via a network.

[0023] In the image memory 26, an original image indicating an image of the original read by the image reading unit 11 is stored.

[0024] The storage unit 27 is a large-capacity storage device such as a solid state drive (SSD) or a hard disk drive (HDD), and stores various application programs and various data.

[0025] The code reader 28 is an imaging camera for reading a QR code (registered trademark).

[0026] The control unit 29 is composed of a processor, a RAM (Random Access Memory), a ROM (Read Only Memory), etc. The processor is, for example, a CPU (Central Processing Unit), an ASIC (Application Specific Integrated Circuit), or an MPU (Micro Processing Unit), etc. The control unit 29 functions as a control unit 31 by the processor executing a control program stored in the ROM or the storage unit 27.

[0027] The control unit 31 comprehensively controls the image forming apparatus 10. The control unit 29 is connected to the image reading unit 11, the image forming unit 12, the display unit 21, the operation unit 22, the touch panel 23, the network communication unit 24, the facsimile communication unit 25, the image memory 26, the storage unit 27, and the code reader 28. The control unit 31 controls the operation of these components and transmits and receives signals or data between these components.

[0028] The control unit 31 serves as a processing unit that executes various processes necessary for image formation by the image forming apparatus 10. The control unit 31 also accepts operation instructions input by a user based on a detection signal output from the touch panel 23 or the operation of a physical key of the operation unit 22. Furthermore, the control unit 31 has a function of controlling the display operation of the display unit 21, and a function of controlling the communication operations of the network communication unit 24 and the facsimile communication unit 25.

[0029] In the image forming apparatus 10 configured as above, the control unit 31 causes the image reading unit 11 to read an original document, and causes image data showing an image of the original document, i.e., an original document image, to be temporarily stored in the image memory 26. Then, the control unit 31 causes the image forming unit 12 to form an image based on the original document image on a recording sheet. The control unit 31 also causes the image reading unit 11 to read an original document, and causes the original document image to be temporarily stored in the image memory 26, and causes the image data to be stored in the storage unit 27 of the image forming apparatus 10, or transmits the image data from the network communication unit 24. The control unit 31 also causes the image reading unit 11 to read an original document, and causes the original document image to be temporarily stored in the image memory 26, and causes the image data to be transmitted from the facsimile communication unit 25 to another image forming apparatus or a facsimile apparatus.

[0030] Here, when the image reading unit 11 reads images of many documents and these images of the documents are classified and saved, it is troublesome for the user to specify the save destination at the time of classification.

[0031] Therefore, the image forming apparatus 10 of the present embodiment is provided with an automatic sorting mode in which the control unit 31 sorts each document image obtained by the image reading unit 11 reading a plurality of documents. When the control unit 31 accepts the setting of the automatic sorting mode, it causes the image reading unit 11 to read a document, and when the document image is read, it extracts a two-dimensional code included in the document image and analyzes the extracted two-dimensional code. Then, the control unit 31 determines the storage destination of the document image indicated by the two-dimensional code, and causes the document image to be stored in the determined storage destination under conditions to be described later. The two-dimensional code is, for example, a QR code (registered trademark), and is assumed to be included in the document image in advance. The storage destination of the document image is the storage unit 27 of the image forming apparatus 10, a storage on a network where data is transmitted and received via the network communication unit 24, and the like.

[0032] FIG. 3(A) shows an example of a document M. FIG. 3(B) shows an example of a QR code included in an image on the document M. As shown in FIG. 3(A), the image formed on the document M includes a plurality of text regions TR1, TR2, TR3, and a region CR, and a QR code Cd is formed in the region CR at a preset position in the image of the document M. As shown in FIG. 3(B), the QR code Cd includes an identifier ID unique to the QR code Cd, an address indicating a storage destination where the document image of the document M is saved, a name of the storage destination, a user name who provided the document image, and a password required to access the storage destination. The storage destination address indicates storage destination information indicating the location of the storage unit 27 of the image forming apparatus 10, an IP address of a storage on a network where data is transmitted and received through the network communication unit 24, and the like. The QR code Cd is created by a user using a known application program and image-formed in the region CR at the preset position on the document M.

[0033] Next, the process of classifying and storing document images in the automatic classification mode will be described in detail with reference to the flow chart shown in FIG.

[0034] The control unit 31 causes the display unit 21 to display an initial screen G1 as shown in Fig. 5, for example. A plurality of function keys 41a to 41h, each associated with a different function, are displayed on the initial screen G1. When the user touches the function key 41h indicating the automatic sorting mode, the control unit 31 receives an instruction to set the automatic sorting mode associated with the function key 41h through the touch panel 23 (S101).

[0035] Next, when the user operates the copy function key 41a displayed on the initial screen G1, the control unit 31 accepts an instruction to execute a copy operation through the touch panel 23. At this time, the user places a plurality of originals on which the QR code Cd is image-formed on the original placement table 1 of the image reading unit 11. Furthermore, the user operates the start key of the operation unit 22. The control unit 31 accepts an instruction to read the originals in response to the operation of the start key, and in accordance with the original reading instruction, causes the image reading unit 11 to sequentially read the images of the originals, and temporarily stores the original images of each original obtained by the original reading in the image memory 26 (S102). Then, the control unit 31 causes the image forming unit 12 to perform image formation based on each original image, and causes each original image to be formed on a recording sheet (S103).

[0036] Alternatively, when the user operates the transmission function key 41b displayed on the initial screen G1, the control unit 31 receives an instruction to execute a scan operation through the touch panel 23. At this time, the user places multiple documents on which QR codes Cd are formed on the document placement table 1 of the image reading unit 11. The user then operates the start key of the operation unit 22. The control unit 31 receives an instruction to read the documents in response to the operation of the start key, and causes the image reading unit 11 to sequentially read the images of the documents in accordance with the document reading instruction, and temporarily stores the document images of each document obtained by reading the documents in the image memory 26 (S102).

[0037] When the user operates the email function key 41c displayed on the initial screen G1 and further inputs an email address indicating the email destination by operating the operation unit 47, the control unit 31 accepts an instruction to execute an email sending operation through the touch panel 23. At this time, the user places a plurality of documents on which the QR code Cd is image-formed on the document placement table 1 of the image reading unit 11. Furthermore, the user operates the start key of the operation unit 22. The control unit 31 accepts an instruction to read the documents in response to the operation of the start key, and in accordance with the document reading instruction, causes the image reading unit 11 to sequentially read the images of the documents, and temporarily stores the document images of each document obtained by the document reading in the image memory 26 (S102). Then, the control unit 31 creates an email addressed to the accepted email address, attaches all of the document images obtained by the document reading to the email, and causes the network communication unit 24 to send the email (S103). Another user on the receiving side receives the email using a terminal device such as a PC, and obtains all of the original images.

[0038] When the process of S103 is completed, since the control unit 31 has received an instruction to execute the automatic classification mode, it analyzes each document image stored in the image memory 26 and extracts the QR code Cd included in each document image from each document image (S105). For example, the control unit 31 executes a known OCR (Optical Character Recognition) function and a text area discrimination function to recognize a text area from each document image, deletes the recognized text area, and recognizes and extracts the QR code Cd from the remaining area different from the text area. In this case, the location indicating the remaining area becomes the above-mentioned preset position. Alternatively, if the control unit 31 stores the position where the QR code Cd should be extracted from the document image as the above-mentioned preset position, it recognizes and extracts the QR code Cd from the preset position.

[0039] For example, as shown in Fig. 3, the control unit 31 recognizes text regions R1, TR2, and TR3 from each document image, deletes each text region R1, TR2, and TR3 from the image of the document M, focuses on a region CR different from each text region R1, TR2, and TR3, and recognizes and extracts the QR code Cd included in this region CR. Alternatively, when a position from which the QR code Cd should be extracted in the image of the document M is preset as shown in Fig. 3, the control unit 31 recognizes and extracts the QR code Cd included in the region CR as the preset position.

[0040] Then, the control unit 31 determines whether or not the QR code Cd included in the document image has been extracted (S106). If the QR code Cd cannot be extracted (S106 "No"), the control unit 31 erases the document image from which the QR code Cd could not be extracted from the image memory 26 (S107).

[0041] Furthermore, when the control unit 31 has extracted the QR code Cd (S106 "Yes"), it analyzes the QR code Cd to determine an identifier ID unique to the QR code Cd indicated by the QR code Cd, address information (location information) indicating the save destination of the image of the document M, the name of the save destination, the user name that provided the document image (the name of the document owner), and a password required to access the save destination (S108).Then, the control unit 31 refers to a registration list DT pre-stored in the storage unit 27 and determines whether the determined save destination (address information (location information) of the save destination) is registered in the registration list DT (S109).

[0042] Fig. 6 shows an example of the registration list DT. In the registration list DT shown in Fig. 6, the storage destinations of document images in the automatic sorting mode, that is, the storage destinations approved as the storage destinations indicated by the QR code Cd, are registered in advance.

[0043] If the storage destination determined in S108 is registered in the registration list DT (S109 "Yes"), the control unit 31 reads out an original image having a QR code Cd including this storage destination from the image memory 26, stores the original image in the storage destination indicated by the address information determined in S108, and erases the original image from the image memory 26 (S110). For example, the control unit 31 identifies a folder in the memory unit 27 that will be the storage destination based on the address information of the storage destination indicated by the QR code Cd, or identifies a storage on the network N through the network communication unit 24. The control unit 31 accesses the storage destination thus identified and outputs the original image. At this time, if a password is required to access the identified storage destination, the control unit 31 accesses it using the password determined above.

[0044] Furthermore, if the storage destination determined in S108 is not registered in the registration list DT (S109 "No"), the control unit 31 reads out an original image having a QR code Cd including this storage destination from the image memory 26, stores the original image in a temporary folder pre-stored in the storage unit 27, and erases the original image from the image memory 26 (S111). At this time, the control unit 31 stores in the temporary folder, in association with the original image, a unique identifier ID for the QR code Cd of the original image, address information (location information) indicating the storage destination of the image of the original M, the name of the storage destination, the user name that provided the original image (the name of the owner of the original), and a password required to access the storage destination.

[0045] The above-mentioned processes from S105 to S111 are performed for each document image. Therefore, after S107, S110, or S111, the control unit 31 determines whether or not there are document images stored in the image memory 26 (S112), and if it determines that document images are still stored (S112 "Yes"), it performs the processes from S105 to S111 for the remaining stored document images.

[0046] Therefore, if the QR code Cd is not extracted from the document image obtained by document reading (S106 "No"), the document image is deleted from the image memory 26 (S107). Also, if the storage destination indicated by the QR code Cd extracted from the document image is registered in the registration list DT (S109 "Yes"), the document image is output and saved in the folder indicated by the QR code Cd, and then deleted from the image memory 26 (S110). Also, if the storage destination indicated by the QR code Cd extracted from the image of the document M is not registered in the registration list DT (S109 "No"), the document image is stored in a temporary folder in the storage unit 27, and then deleted from the image memory 26 (S111).

[0047] In this way, when the QR codes Cd are extracted from the original images of multiple originals M, and the storage destinations indicated by these QR codes Cd are registered in the registration list DT, the storage destinations (information on the addresses of the storage destinations), the names of the storage devices, the passwords, and the like indicated by the QR codes Cd are determined, and the original images are read out from the image memory 26 and output and stored in the respective storage destinations. As a result, for each original M, the original images of each original M are sorted and classified into folders X, Y, Z, and the like as the respective storage destinations, as shown in FIG.

[0048] When the control unit 31 determines that there are no more document images stored in the image memory 26 (S112 "No"), the process ends.

[0049] According to this embodiment, the document image obtained by scanning the document is stored in the storage destination indicated by the QR code Cd extracted from the document image, provided that the storage destination matches the storage destination registered in the registration list DT, so that the document images can be appropriately allocated and stored in the respective storage destinations registered for each document image while ensuring security. As a rule, the document image obtained by scanning the document is not stored if the storage destination indicated by the QR code Cd extracted from the document image is not registered in the registration list DT, so even if an unauthorized user who does not know the existence of the registration list DT creates a QR code Cd on a document without permission and has the image reading unit 11 read the document, the document will not be classified and stored in the automatic classification mode.

[0050] Next, the processing of the document image stored in the temporary folder will be described with reference to the flowchart of FIG 8.

[0051] Regardless of whether the automatic sorting mode is being executed or not, the control unit 31 determines whether image data representing an original image is stored in the temporary folder of the storage unit 27 (S113). When the control unit 31 determines that image data representing an original image is not stored in the temporary folder of the storage unit 27 (S113 "No"), the process ends.

[0052] On the other hand, when the control unit 31 determines that image data indicating an original image is stored in a temporary folder of the memory unit 27 (S113 "Yes"), that is, when the storage destination indicated by the QR code Cd included in the original image is not registered in the registration list DT and an original exists that has been destined to be stored in the temporary folder of the memory unit 27, it selects one of the original images stored in the temporary folder (S114) and identifies the storage destination stored in association with this selected original image (S115).

[0053] Then, the control unit 31 judges whether the specified storage destination is registered in the registration list DT (S116). When the control unit 31 judges that the specified storage destination is registered in the registration list DT (YES in S116), the control unit 31 reads the selected original image from the temporary folder, stores it in the storage destination judged to be registered, and deletes it from the temporary folder (S117). After this, the process ends. Here, the user can register a new destination for saving the document images in the automatic sorting mode used as the destination indicated by the QR code Cd in the registration list DT. In this case, the user operates the operation unit 47 to input the name and address information indicating the newly added destination. Each time this input is made, the control unit 31 registers the name and address information indicating the newly added destination in the registration list DT. Therefore, even if the destination is not registered in the registration list DT at the time of the processing of S109, if a new destination is registered in the registration list DT after the processing of S109, the control unit 31 moves the document images stored in the temporary folder to the newly registered destination and saves them there.

[0054] In this embodiment, when the image of the original M is read by the image reading unit 11 with the automatic classification mode set, the QR code Cd contained in the image of the original M is extracted, the storage destination of the image of the original M indicated by the QR code Cd is determined, and the original image of the original M is stored in this storage destination, so that the original images of multiple originals M are appropriately sorted and classified into the individual storage destinations set for each.

[0055] In addition, the control unit 31 accepts the storage destination input by the user operating the operation unit 47 before starting the document reading operation in the automatic sorting mode, and if the storage destination indicated by the QR code Cd included in the document image obtained by the document reading matches the storage destination indicated by the QR code Cd, the control unit 31 may be configured to save the document image in the storage destination indicated by the QR code Cd even if the storage destination indicated by the QR code Cd included in the document image obtained by the document reading is not registered in the registration list DT.

[0056] Also, the unique identifier ID of the QR code Cd may be registered in the registration list DT together with the storage destination. In this case, the control unit 31 stores the document image in the storage destination indicated by the QR code Cd only when the unique identifier ID and storage destination indicated by the QR code Cd extracted from the document image obtained by document scanning are registered in the registration list DT.

[0057] The information processing device according to one embodiment of the present invention is, for example, a personal computer or the like, and includes at least an image reading unit 11 and a control unit 31. The image forming unit 12 is not an essential component of the information processing device according to one embodiment of the present invention.

[0058] In the above embodiment, an image forming apparatus is taken as an example, but the document image classification method of the present invention can be applied to other types of apparatus, such as a copy machine and a facsimile machine.

[0059] Moreover, the configurations and processes of the above-described embodiment described with reference to FIGS. 1 to 7 are merely examples of the present invention, and the present invention is not limited to these configurations and processes. [Explanation of symbols]
