[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The following embodiment is an example of the present invention, and is not intended to limit the technical scope of the present invention.

[0014] (Embodiment 1) [1] Overall configuration of image processing device First, the overall configuration of an image processing device 10 according to this embodiment will be described with reference to FIGS.

[0015] The image processing device 10 according to the present embodiment is, for example, a multifunction device having multiple functions such as a scanning function for acquiring image data from an original, a printing function for forming an image based on image data, a facsimile function, and a copy function. The image processing device 10 only needs to have an image processing function including at least one of a function for forming an image and a function for acquiring image data, and may be a printer, a scanner, a facsimile machine, a copy machine, or the like.

[0016] As shown in FIG. 2, the image processing device 10 is roughly divided into a main body 1 (main unit) and an extension device 2 (enhancement unit). The main body 1 has an image processing function (at least one of a function of forming an image and a function of acquiring image data). The "extension device" in this disclosure is a device that is removably connected to the main body 1, and is an enhancement that adds various extension functions to the image processing device. The main body 1 and the extension device 2 are used in a state of being electrically and mechanically connected. That is, the image processing device 10 can realize various extension functions desired by the user by combining the main body 1 with the desired extension device 2 while based on the functions of the main body 1. Specific examples of the extension device 2 include devices such as a stapler, a folding machine, an inserter, a booklet folder, and a mail folder. These extension devices 2 perform post-processing such as stapling on sheets on which an image is formed by the main body 1, for example.

[0017] In the present embodiment, as an example, the image processing device 10 includes a finisher having a function as a stapler as the extended device 2, and further includes any extended device 2 selected from a folder, an inserter, a booklet folder, a mail folder, etc. In other words, the image processing device 10 is capable of connecting one or more extended devices 2 to one main body 1.

[0018] 1, the main body 1 of the image processing device 10 includes an automatic document feeder 11, an image reading unit 12, an image forming unit 13, a paper feed unit 14, a display unit 15, an operation unit 16, a control unit 17, a memory unit 18, and a storage device 19. The automatic document feeder 11 is an ADF (Auto Document Feeder), and is therefore indicated as "ADF" in FIG. 1, and will also be referred to as "ADF 11" in the following description.

[0019] The ADF 11 transports an original document whose image is to be read by the image reading unit 12. The ADF 11 includes an original document setting unit, a plurality of transport rollers, an original document pressing unit, and a paper ejection unit.

[0020] The image reading unit 12 reads an image from a document and outputs image data corresponding to the read image. The image reading unit 12 includes a document table, a light source, a plurality of mirrors, an optical lens, a CCD (Charge Coupled Device), and the like.

[0021] The image forming unit 13 forms an image on a sheet by an electrophotographic method based on image data output from the image reading unit 12. The image forming unit 13 also forms an image on a sheet based on image data input from an information processing device external to the image processing device 10, such as a personal computer. The image forming unit 13 has four image forming units corresponding to four colors, C (cyan), M (magenta), Y (yellow), and K (black), an optical scanning device, an intermediate transfer belt, a secondary transfer roller, a fixing device, and the like. The image forming unit 13 may be configured to form an image on a sheet by an image forming method other than the electrophotographic method, such as an inkjet method, for example.

[0022] The image forming unit 13 forms an image on a sheet using toner as a developer. When the image forming unit 13 forms an image by an inkjet method, ink (another example of a developer) is supplied instead of toner. Examples of toner supplied to the image forming unit 13 include toner of multiple colors, such as C (cyan), M (magenta), Y (yellow), and K (black). After the image is formed in the image forming unit 13, the sheet is discharged (supplied) to an extension device or the like for post-processing.

[0023] The paper feed unit 14 supplies a sheet to the image forming unit 13. The paper feed unit 14 has a paper feed cassette, a manual feed tray, a sheet transport path, a plurality of transport rollers, etc. The image forming unit 13 forms an image on the sheet supplied from the paper feed unit 14. The sheet supplied to the image forming unit 13 is paper as an example, but is not limited to paper and may be, for example, a resin film, etc.

[0024] The display unit 15 is a user interface for presenting (displaying) information to a user in the image processing device 10. The display unit 15 displays various information in response to a control instruction from the control unit 17. As an example in the present embodiment, the display unit 15 includes a liquid crystal display, and displays a display screen including various information on the liquid crystal display.

[0025] The operation unit 16 is, for example, a user interface for accepting operation input by a user to a display screen displayed on the display unit 15. The operation unit 16 accepts various operations by a user, for example, by outputting an electrical signal according to the user's operation. As an example in this embodiment, the operation unit 16 has a switch, a touch panel, or the like.

[0026] Furthermore, the image processing device 10 may include, in addition to or instead of the display unit 15 and the operation unit 16, for example, an audio output unit and an audio input unit, etc., as a user interface.

[0027] The control unit 17 mainly comprises a computer system having one or more processors and one or more memories, and performs overall control of the image processing device 10. In the image processing device 10, the one or more processors execute programs to realize the functions of the control unit 17. In this embodiment, as an example, the control unit 17 includes a CPU (Central Processing Unit).

[0028] The program may be pre-recorded in one or more memories, or may be provided via a telecommunication line such as the Internet, or may be provided by recording it in a non-transitory recording medium readable by a computer system, such as a memory card or an optical disk. The one or more processors are composed of one or more electronic circuits including a semiconductor integrated circuit. Furthermore, the computer system referred to here includes a microcontroller having one or more processors and one or more memories. The control unit 17 may be a control unit provided separately from a main control unit that comprehensively controls the image processing device 10.

[0029] The storage unit 18 includes one or more non-volatile memories, and stores information such as control programs for causing the control unit 17 to execute various processes in advance.

[0030] The storage device 19 includes, for example, an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and a part of the storage area is used as a data area for storing image data, etc. In other words, various data are input to the image processing device 10, and the image processing device 10 is equipped with a relatively large capacity storage device 19 so that the data can be processed in parallel. Therefore, for example, when the print process is to be executed again due to a failure of the print process or an insufficient number of output copies, the image processing device 10 can read out the image data stored in the storage device 19 and execute the print process.

[0031] Moreover, data such as image data can be encrypted before being stored in the storage device 19. For this reason, the image processing device 10 has an encryption function for encrypting data and a decryption function for decrypting data when reading it out.

[0032] Here, the storage device 19 is removably attached to the main body 1 of the image processing device 10. In other words, the storage device 19 is separate from the main body 1, is attached to a predetermined attachment portion of the main body 1, and can be removed from the main body 1 (its attachment portion) during maintenance or the like. Furthermore, when the storage device 19 is attached to the main body 1, it is detachably connected to the main body 1 by a connecting device such as a connector. As a result, when the storage device 19 is attached to the main body 1 (its attachment portion), it becomes capable of communicating with the control unit 17 and the like, and can be used as the storage device 19 of the image processing device 10.

[0033] The image processing device 10 further includes a communication unit etc. The communication unit is an interface that executes data communication between the image processing device 10 and an external device connected via a communication network such as the Internet or a LAN (Local Area Network).

[0034] As a related technique to this type of creation support device, there is known an image processing device that temporarily stores electronic data of a document in a memory unit within the device for processing. This image processing device is equipped with a large-capacity storage device such as a hard disk, and is capable of accepting multiple data processing requests and processing them sequentially.

[0035] In this image processing device, the device itself can erase and invalidate data after processing, so that data remaining in the device does not become a problem. In a related technology, the image processing device erases data and stores a history of the data being erased (invalidated).

[0036] Due to the increasing demand for security in recent years, various erasing means may be required, and if the image processing device is not equipped with the required erasing means, it is necessary to remove the storage device from the image processing device and erase the data using a personal computer, etc. However, if data is erased using a personal computer, etc., it is not possible to leave a history of the data erasure on the image processing device, which reduces the reliability of management related to data erasure.

[0037] In contrast to this, in this embodiment, the configuration described below realizes a storage management system 30, an image processing device 10, a storage management method and a program that can easily improve the reliability of management related to data erasure.

[0038] [2] Storage management system Next, the configuration of a storage management system 30 for managing the storage device 19 will be described with reference to FIG.

[0039] 3, the storage management system 30 includes an erasure processing unit 31, a writing processing unit 32, an acquisition processing unit 171, and an output processing unit 172. In this embodiment, the erasure processing unit 31 and the writing processing unit 32 are provided in an information processing device 3 external to the image processing device 10, such as a personal computer, and the acquisition processing unit 171 and the output processing unit 172 are provided in the control unit 17 of the image processing device 10.

[0040] That is, in this embodiment, the components of the storage management system 30, that is, the erasure processing unit 31, the writing processing unit 32, the acquisition processing unit 171 and the output processing unit 172, are distributed among the information processing device 3 such as a personal computer, and the image processing device 10. In other words, the storage management system 30 includes the information processing device 3 and the control unit 17 of the image processing device 10. The image processing device 10 includes the acquisition processing unit 171 and the output processing unit 172 as functions of the control unit 17.

[0041] In this embodiment, the functions of the erasing processing unit 31 and the writing processing unit 32 are realized by a utility application for the image processing device 10 installed in the information processing device 3. That is, the information processing device 3 operates as the erasing processing unit 31 and the writing processing unit 32 by starting the utility application for the image processing device 10.

[0042] The erasure processing unit 31 executes an erasure process for erasing data in the storage device 19 that has been removed from the image processing device 10. That is, since the storage device 19 is removably attached to the main body 1 of the image processing device 10, the erasure processing unit 31 erases the data in the storage device 19 in a state in which the storage device 19 is removed from the main body 1.

[0043] When erasing data from the storage device 19 removed from the image processing device 10, the write processing unit 32 saves erasure certification information D1 (see FIG. 4) including the identifier D11 (see FIG. 4) of the storage device 19 in a specific area R1 (see FIG. 4) of the storage device 19. The "erasure certification information" in this disclosure is information that certifies that data from the storage device 19 has been erased, and is, for example, image data of the erasure certificate and / or an erasure log. In addition to the identifier D11 of the storage device 19, the erasure certification information D1 includes, for example, information on the date and time of erasure and the device that performed the erasure. Here, the "identifier" of the storage device 19 is a code (including a number) unique to the storage device 19, and is, for example, a serial number or a MAC address (Media Access Control address).

[0044] The acquisition processing unit 171 executes an acquisition process to acquire the identifier D12 of the storage device 19 attached to the image processing device 10. That is, since the storage device 19 is removably attached to the main body 1 of the image processing device 10, the acquisition processing unit 171 acquires the identifier of the storage device 19 from the storage device 19 while the storage device 19 is attached to the main body 1. In the following description, the identifier acquired by the acquisition processing unit 171 will be referred to as "identifier D12" (see FIG. 6) when distinguishing it from the identifier D11 included in the erasure certificate information D1.

[0045] The output processing unit 172 executes an output process to output the erasure certificate information stored in the storage device 19 attached to the image processing device 10 together with the identifier D12 acquired by the acquisition processing unit 171. That is, since the storage device 19 is removably attached to the main body 1 of the image processing device 10, while the storage device 19 is attached to the main body 1, the output processing unit 172 acquires the erasure certificate information D1 stored in the storage device 19 from the storage device 19 and outputs it together with the identifier D12 acquired by the acquisition processing unit 171.

[0046] Examples of the output by the output processing unit 172 include printing, display on the display unit 15, audio output, writing to a recording medium, and transmission to another terminal. In the present embodiment, as an example, the output processing unit 172 causes the image processing device 10 to print image data having the identifier D11 included in the erasure certificate information D1 and the identifier D12 acquired by the acquisition processing unit 171. This makes it possible to use the image processing device 10 to output the identifier D11 included in the erasure certificate information D1 and the identifier D12 acquired by the acquisition processing unit 171 in a visible state.

[0047] [3] Storage management method Next, a storage management method executed by the storage management system 30 according to this embodiment will be described with reference to Figures 3 to 7. The (storage management) program according to this embodiment is a computer program for causing one or more processors in an information processing device 3 external to the image processing device 10 and one or more processors in the control unit 17 of the image processing device 10 to execute the storage management method.

[0048] According to the storage management method of this embodiment, it is possible to erase data in the storage device 19 of the image processing device 10. "Erasing" here does not only mean making the data stored in the storage device 19 physically non-existent, but also includes invalidating the data so that it cannot be accessed.

[0049] 3 to 6 show a schematic diagram of a series of processes relating to erasing data from the storage device 19 using the storage management system 30 according to this embodiment.

[0050] 3, a user (operator) removes the storage device 19 from the image processing device 10 and connects the removed storage device 19 to the information processing device 3. This makes the information processing device 3 capable of sending and receiving data bidirectionally with the storage device 19.

[0051] Next, as shown in FIG. 4, with the storage device 19 connected, the information processing device 3 launches a utility application and erases data from the storage device 19 (erasure process) and writes erasure certification information D1 (write process).

[0052] That is, the erasure processing unit 31 of the information processing device 3 erases the data in the storage device 19 that has been removed from the image processing device 10. At this time, the erasure processing unit 31 performs overwriting and erasing for the entire memory area of ​​the storage device 19.

[0053] When the erasure process is completed, the write processing unit 32 of the information processing device 3 creates erasure certification information D1 including the identifier D11 (as an example, a serial number) of the storage device 19 acquired from the storage device 19. Then, the write processing unit 32 saves the erasure certification information D1 in a specific area R1 of the storage device 19. The specific area R1 is a specific sector that has been determined in advance within the memory area of ​​the storage device 19.

[0054] 5, the user (operator) removes the storage device 19 from the information processing device 3, and attaches (connects) the removed storage device 19 to the image processing device 10. This makes the image processing device 10 capable of sending and receiving data bidirectionally with the storage device 19.

[0055] At this time, the image processing device 10 formats (initializes) the storage device 19 in a predetermined format to make the storage device 19 available. However, the image processing device 10 prevents data erasure (including overwriting) and modification from being performed on the specific area R1 of the storage device 19 in which the erasure certification information D1 is stored.

[0056] 6, the image processing device 10 receives a print instruction Si1 for the erasure certificate D2 in the storage device 19 and prints the erasure certificate D2. As an example, the print instruction Si1 for the erasure certificate D2 is transmitted from the information processing device 3 to the image processing device 10 directly or indirectly via a repeater or the like. Specifically, the information processing device 3 starts a utility application and transmits the print instruction Si1 for the erasure certificate D2 in the storage device 19 to the image processing device 10.

[0057] When the image processing device 10 receives a print instruction Si1 for the erasure certificate D2 while the storage device 19 is connected, the image processing device 10 acquires an identifier D12 (acquisition process) for the storage device 19 and outputs the erasure certificate information D1 (output process).

[0058] That is, the acquisition processing unit 171 of (the control unit 17 of) the image processing device 10 acquires the identifier D12 (for example, a serial number) of the storage device 19 attached to the image processing device 10 from the storage device 19.

[0059] When the acquisition process is completed, the output processing unit 172 of the image processing device 10 (the control unit 17 thereof) adds the identifier D12 acquired by the acquisition processing unit 171 to the erasure certificate information D1 stored in the specific area R1 of the storage device 19, and creates image data for printing. The image data created at this time includes both the identifier D11 included in the erasure certificate information D1 and the identifier D12 acquired by the acquisition processing unit 171. As a result, as shown in FIG. 6, the erasure certificate D2 printed by the image processing device 10 includes both the identifier D11 written by the information processing device 3 and the identifier D12 acquired by the acquisition processing unit 171.

[0060] According to the storage management method described above, data erasure of the storage device 19 is performed by the information processing device 3 outside the image processing device 10 for the storage device 19 removed from the image processing device 10. Therefore, due to the increasing demand for security in recent years, even if the image processing device 10 does not have the required erasure means, data can be erased by the information processing device 3 such as a personal computer.

[0061] Moreover, since both the identifier D11 written by the information processing device 3 and the identifier D12 acquired by the acquisition processing device 171 can be confirmed in the erasure certificate D2 output by the output processing unit 172, the validity of the erasure certification information D1 is guaranteed by the fact that the identifier D11 and the identifier D12 match. In short, the identity of the individual storage device 19 from which data has been erased and the individual storage device 19 attached to the image processing device 10 is proven. As a result, it is possible to realize a storage management system 30, image processing device 10, and storage management method and program that can easily improve the reliability of management related to data erasure.

[0062] An example of processing for erasing data from the storage device 19 using the storage management system 30 according to this embodiment will be described below with reference to Fig. 7. Here, steps S1, S2, etc. in the flowchart shown in Fig. 7 each indicate the number of a processing procedure (step) executed by the storage management system 30.

[0063] <Step S1> In step S1, the erasure processing unit 31 of the information processing device 3 erases data from the storage device 19 that has been removed from the image processing device 10 and connected to the information processing device 3 (erasure process).

[0064] <Step S2> In step S2, the write processing unit 32 of the information processing device 3 creates erasure certificate information D1 including the identifier D11 of the storage device 19 acquired from the storage device 19, and writes it to the specific area R1 of the storage device 19 (write process).

[0065] <Step S3> In the next step S3, the control unit 17 of the image processing device 10 judges whether or not a storage device 19 is attached to the main body 1 of the image processing device 10. If the storage device 19 is attached to the main body 1 (S3: Yes), the control unit 17 shifts the process to step S4. If the storage device 19 is not attached to the main body 1 (S3: No), the control unit 17 repeats step S3.

[0066] <Step S4> In step S4, the acquisition processing unit 171 of the image processing device 10 acquires the identifier D12 of the storage device 19 attached to the image processing device 10 from the storage device 19 (acquisition process).

[0067] <Step S5> In the next step S5, the output processing unit 172 of the image processing device 10 creates image data for printing by adding the identifier D12 acquired in step S4 to the erasure certification information D1 stored in the specific area R1 of the storage device 19. The image data created at this time is used to cause the image processing device 10 to print the erasure certificate D2, thereby outputting the erasure certification information D1 and the identifier D12 (output processing).

[0068] The above-described procedure is merely an example, and the order of the processes shown in the flowchart of FIG. 13 may be changed as appropriate.

[0069] [4] Variations The multiple components included in the storage management system 30 may be distributed across multiple housings. For example, one of the acquisition processing unit 171 and the output processing unit 172 may be provided separately.

[0070] In addition, the manner of output by the output processing unit 172 is not limited to printing (the erasure certificate D2) as described above. For example, the output processing unit 172 may output the image data of the erasure certificate D2 as an image file by displaying it on the display unit 15, writing it on a recording medium, or transmitting it to another terminal.

[0071] In the first embodiment, the function of the erasure processing unit 31 is realized by a utility application for the image processing device 10 installed in the information processing device 3, but this is not limited to the example. That is, the erasure processing unit 31 is not an essential component of the storage management system 30, and the information processing device 3 may realize the function of the erasure processing unit 31 by an arbitrary data erasure application. Even in this case, it is preferable that the function of the writing processing unit 32 is realized by a utility application for the image processing device 10.

[0072] In short, when the information processing device 3 starts an arbitrary data erasure application and erases data from the storage device 19, the data erasure application creates unique erasure certification information D1. In this case, the writing processing unit 32 stores the erasure certification information D1 in a specific area R1 of the storage device 19 in a format including at least the identifier D11 of the storage device 19.

[0073] For example, depending on the user's rules, it may be required to erase data from various devices in the same manner using a common data erasure application. In such a case, it is preferable to realize the function of the erasure processing unit 31 by using an arbitrary data erasure application.
