DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] [First embodiment] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

[0010] First, with reference to FIG. 1, an overview of a service (hereinafter referred to as "this service") to which a shredder system (see FIG. 2 described later) to which the present invention is applied will be described.

[0011] FIG. 1 is a diagram showing an overview of an example of a service that can be realized by a shredder system according to an embodiment of the present invention, in comparison with a conventional service.

[0012] This service is provided to a user K who manages a subordinate H, for example, and who works in an office. Specifically, for example, when a medium P that should not have been discarded is shredded by subordinate H without permission, causing the information fixed on the medium P to be lost, the information fixed on the medium P is restored and provided to user K as a service.

[0013] Conventionally, confidential information is fixed by printing or the like on a medium P such as paper used in an office, etc. Therefore, when this medium P becomes unnecessary, a shredder technology is used that makes it impossible to identify the confidential information by shredding the medium P in order to prevent the confidential information fixed on the medium P from being identified and diverted by a third party. While shredder technology makes it possible to protect privacy and prevent information leaks by shredding media P, it is also characterized by the fact that it is extremely difficult to restore shredded media P. For this reason, shredders are not only used for the purposes of protecting privacy and preventing information leaks, but there are also many cases where people who do not want media P to be restored use shredders intentionally to destroy information.

[0014] Specifically, in an office or the like, medium P on which information regarding a contract with a customer is printed may be disadvantageous to subordinate H (e.g., it may prove his / her own mistake), so subordinate H may not want user K, who is his / her superior, to see it. For this reason, let us assume a case in which subordinate H intentionally destroys medium P. However, since medium P contains information regarding a contract with a customer, it is considered an important document in the office or the like (especially for user K) and is treated as something that cannot be discarded. For example, assume that subordinate H negligently contaminates medium P. To avoid being criticized by user K for contaminating medium P, subordinate H destroys medium P, which is evidence of his negligence, in an attempt to cover up the negligence. In other words, subordinate H destroys medium P by shredding the contaminated medium P with a shredder so that it cannot be restored, thereby destroying the existence of medium P. As a result, the information that was fixed on medium P by printing or the like is also destroyed. Conventionally, user K was unable to detect that medium P (i.e., the information fixed on that medium P) had been destroyed by subordinate H. As a result, when the information printed on medium P was to be reused at a later date, it was discovered that medium P had been lost, which caused further trouble.

[0015] Also, although not shown, there are many cases where media P are shredded by mistake, not intentionally. As described above, the shredder technology has the characteristic that it is extremely difficult to restore media P once it has been shredded. Therefore, when inserting media P into a shredder, it is necessary to carefully check whether it is really OK to discard the media P. However, in an office or the like where a large amount of media is handled, it is troublesome and difficult due to time constraints to accurately check whether it is really OK to discard the media P every time it is inserted into the shredder. As a result, it has been common for media P that should not be discarded to be inserted into the shredder by mistake, resulting in the loss of information.

[0016] In contrast to the conventional problems described above, as shown on the left side of Figure 1, the present service, as shown on the right side of Figure 1, makes it possible to restore information fixed on medium P, even after medium P has been shredded by shredder 1. Specifically, for example, even if subordinate H intentionally or accidentally inserts medium P into shredder 1, the following series of processes are executed. That is, before medium P is shredded, it is scanned by scanner device 11 built into shredder 1, and information fixed to medium P is read. The read information is transmitted to and stored in server 2, which will be described later in FIG. 2. As a result, the information fixed to medium P inserted into shredder 1 is stored in server 2 before shredding. After the fixed information on the medium P is read by a scanner device 11, the medium P is sent to a cutting section 12 and shredded. User K uses the supervisor terminal 3 to search for and extract information on the medium P stored in the server 2. In this way, user K can restore information that was lost when the medium P was inserted into the shredder 1 by subordinate H.

[0017] The outline of the present service to which the shredder system to which the present invention is applied has been described above with reference to FIG. FIG. 2 is a system configuration diagram of a shredder system according to one embodiment of the present invention.

[0018] The shredder system shown in FIG. 2 is configured to include a shredder 1, a server 2, and a supervisor terminal 3. The shredder 1, the server 2, and the supervisor terminal 3 are connected to each other via a predetermined network N such as the Internet. The form of the network N is not particularly limited, and may be, for example, Bluetooth (registered trademark), Wi-Fi, a LAN (Local Area Network), the Internet, or the like.

[0019] The shredder 1 is installed, for example, in an office and is operated by a subordinate H or the like.

[0020] The server 2 is an information processing device managed by, for example, a system administrator (not shown) under the supervision of the user K. The server 2 executes various processes while communicating with the shredder 1 and the supervisor terminal 3 as appropriate. The person who performs the duties of the system administrator is not particularly limited. For example, the user K himself may perform the duties of the system administrator.

[0021] The monitor terminal 3 is an information processing device that is installed in an office or the like and is operated by a user K. Specifically, for example, the monitor terminal 3 is configured with a personal computer, a smartphone, a tablet, or the like.

[0022] Next, an example of the hardware configuration of the shredder 1 constituting the above-mentioned shredder system will be described with reference to FIG. FIG. 3 is a perspective view showing an example of the external configuration of a shredder in the system configuration of the shredder system according to one embodiment of the present invention. It is assumed that the shredder 1 is placed as shown in Fig. 3 with respect to the plane (XY plane) formed by the X-axis and Y-axis shown in the figure. Therefore, hereinafter, the direction of the X-axis will be called the "horizontal direction", the direction of the Y-axis will be called the "depth direction", the upward direction of the Z-axis in the figure will be called the "upward direction", and the downward direction of the Z-axis in the figure will be called the "downward direction".

[0023] As shown in FIG. 3, the shredder 1 includes a scanner device 11, a cutting section 12, a housing section 13, and a top panel section . A top panel 14 is attached to the top of the housing 13. The top panel 14 is provided with an insertion port 15 for inserting the medium P. Scanner device 11 is built into housing 13 and is disposed directly below input port 15 provided on top panel 14. Scanner device 11 is a device that reads information fixed to medium P by printing or the like and converts it into digital image data. That is, scanner device 11 reads information fixed to medium P by moving medium P with an automatic document feeder (not shown). Scanner device 11 then converts the read information into digital image data and outputs it to the outside.

[0024] The cutting unit 12 is built into the housing 13 and disposed below the scanner device 11. The cutting unit 12 uses fine blades to crush the medium P that has been moved by the scanner device 11 (automatic document feeder).

[0025] That is, when the medium P is inserted into the shredder 1 through the insertion slot 15, the medium P is sent to the scanner device 11. The information fixed on the medium P is read by the scanner device 11, converted into digital image data, and transmitted to the server 2. Thereafter, the medium P is moved from the scanner device 11 to the cutting section 12 and is shredded.

[0026] Next, an example of a hardware configuration of the server 2 constituting the above-mentioned shredder system will be described with reference to FIG. FIG. 4 is a block diagram showing a hardware configuration of a server in the shredder system according to one embodiment of the present invention.

[0027] The server 2 includes a CPU (Central Processing Unit) 21, a ROM (Read Only Memory) 22, a RAM (Random Access Memory) 23, a bus 24, an input / output interface 25, an input unit 26, an output unit 27, a memory unit 28, a communication unit 29, and a drive 30.

[0028] The CPU 21 executes various processes according to a program recorded in the ROM 22 or a program loaded from the storage unit 28 into the RAM 23 . The RAM 23 also stores data and the like necessary for the CPU 21 to execute various processes.

[0029] The CPU 21, the ROM 22, and the RAM 23 are connected to one another via a bus 24. An input / output interface 25 is also connected to the bus 24. An input unit 26, an output unit 27, a storage unit 28, a communication unit 29, and a drive 30 are connected to the input / output interface 25.

[0030] The input unit 26 is configured with, for example, a keyboard, and various information is inputted therein. The output unit 27 is composed of a display such as a liquid crystal display, a speaker, and the like. The storage unit 28 is configured with a dynamic random access memory (DRAM) or the like, and stores various data. The communication unit 29 communicates with other devices (such as the shredder 1 in FIG. 3) via a network N including the Internet.

[0031] Removable media 31, such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory, is appropriately loaded into the drive 30. A program read from the removable media 31 by the drive 30 is installed in the storage unit 28 as necessary. Further, the removable medium 31 can store various data stored in the storage unit in the same manner as the storage unit .

[0032] Although not shown, the supervisor terminal 3 in Fig. 2 can also have a configuration basically similar to the hardware configuration of the server 2 shown in Fig. 4. Therefore, a description of the configuration of the supervisor terminal 3 will be omitted.

[0033] Next, with reference to FIG. 5, the functional configurations of the shredder 1, the server 2, and the supervisor terminal 3 having the hardware configurations shown in FIG. 3 and FIG. 4 will be described. FIG. 5 is a functional block diagram illustrating an example of a functional configuration of the server illustrated in FIG.

[0034] The shredder 1 is made up of a scanner device 11 and a cutting section 12 . Moreover, in the scanner device 11 of the shredder 1, a reading section 111, a main control section 112, and a communication section 113 function. Furthermore, in the main control section 112, an acquisition section 121 and a transmission control section 122 are provided.

[0035] In the CPU 21 of the server 2, an information acquisition unit 201, an information management unit 202, an information reading unit 203, and a display control unit 204 function. In addition, an acquired information DB 40 is provided in one area of ​​the storage unit 28 of the server 2.

[0036] For example, when subordinate H or the like inserts medium P into insertion slot 15 provided on top panel 14 of shredder 1, a series of operations is started. When a medium P is inserted through an inlet 15 of the shredder 1, the medium P is moved to a scanner device 11. The reading unit 111 of the scanner device 11 reads information fixed on the medium P by printing or the like. The acquisition unit 121 of the main control unit 112 converts the information of the medium P read by the reading unit 111 into digital image data and acquires it. The transmission control unit 122 of the main control unit 112 executes control to transmit information about the medium P acquired in the form of digital image data to the server 2 via the communication unit 113 . Furthermore, the medium P from which information has been read by the reading unit 111 of the scanner device 11 is sent to the shredding unit 12 of the shredder 1 and shredded.

[0037] The information acquisition unit 201 of the server 2 acquires the information (digital image data) transmitted from the shredder 1 via the communication unit 29. The information management unit 202 stores the information acquired by the information acquisition unit 201 in the acquired information DB 40 so that it can be recognized as information on the medium P, thereby managing the information so that it can be read out as information on the medium P.

[0038] When the user K wishes to refer to the information on the medium P, the user K accesses the server 2 via the supervisor terminal 3 to issue an instruction to read out the information.

[0039] When the information reading unit 203 of the server 2 receives an instruction to read information from the supervisor terminal 3, it searches the acquired information DB 40 for information on the medium P. Specifically, the information reading unit 203 acquires a read instruction transmitted from the monitor terminal 3 via the communication unit 29. Then, the information reading unit 203 reads information of the medium P from the acquired information DB 40 via the information management unit 202.

[0040] Here, the information management unit 202 can store information about the medium P in the acquired information DB 40 in association with various metadata. Therefore, the user K may instruct the reading of information on the medium P by using the metadata as a keyword.

[0041] Specifically, for example, if the information on medium P is information about a contract, shredder 1 can generate metadata called "contract" by performing character recognition or the like when reading the information on medium P, and output the metadata by associating it with the information (digital image data) on medium P. In this case, when user K wants to read information about a contract, he or she can input the keyword "contract" to smoothly search for and extract the information on medium P associated with the metadata called "contract" from the information on various types of medium P stored in the acquired information DB 40.

[0042] Also, for example, the date on which information on medium P was read by shredder 1 may be associated as metadata with the information on medium P. In this case, if user K wants to read information on medium P read by shredder 1 on "month x day", by inputting "month x day", the information on medium P associated with the metadata "month x day" can be smoothly searched and extracted from the information on various types of medium P stored in acquired information DB 40.

[0043] The display control unit 204 of the server 2 executes control to display the information of the medium P read by the information reading unit 203 on the monitor terminal 3 via the communication unit 29 .

[0044] The monitor terminal 3 acquires information about the medium P in an acquisition unit (not shown) and displays the information on a display (not shown).

[0045] An example of the functional configuration of the shredder 1, the server 2, and the supervisor terminal 3 has been described above with reference to FIG.

[0046] [Second embodiment] In the shredder 1 described in the first embodiment, the scanner device 11 is built into the housing 13 of the shredder 1. The medium P inserted through the insertion slot 15 has fixed information read by the scanner device 11 (automatic document feeder), which is then converted into digital image data and transmitted to the server 2. Meanwhile, the medium P is moved to the cutting unit 12 located below the scanner device 11 and shredded. That is, in the first embodiment, reading of information fixed on the medium P and shredding of the medium P are executed as a series of processes. Therefore, in the first embodiment, only the storage and restoration of information is performed, and shredding of the actual medium P cannot be prevented. Therefore, as a second embodiment, the medium P inserted through the insertion port 15 may be configured so that after the fixed information is read by the scanner device 11 (automatic document feeder), the medium P is stored in a predetermined position for a certain period of time before being moved to the cutting section 12. A specific example of the second embodiment will be described below with reference to FIG.

[0047] FIG. 6 is a perspective view showing an example of the external configuration of a shredder in the system configuration of a shredder system according to one embodiment of the present invention, and is a view different from FIG. The shredder 1 is placed on the plane (XY plane) formed by the X-axis and Y-axis shown in Fig. 6 as shown in the figure. As described above in Fig. 3, the direction of the X-axis is called the "horizontal direction", the direction of the Y-axis is called the "depth direction", the upward direction of the Z-axis in the figure is called the "upward direction", and the downward direction of the Z-axis in the figure is called the "downward direction".

[0048] 6, the shredder 1 in the second embodiment is composed of a storage container 16 and a crusher 20. The storage container 16 includes a scanner device 11, a housing unit 17, and a top plate unit 18, and the crusher 20 includes a cutting unit 12, a housing unit 13, and a top plate unit 14. In the storage container 16, a top plate portion 18 is attached to the top of the housing portion 17. The top plate portion 18 is provided with an insertion port 19 for inserting the medium P. The scanner device 11 is built into a housing 17 and disposed directly below an input port 19 of a top panel 18 . In the crusher 20, a top plate portion 14 is attached to the upper portion of the housing portion 13. The top plate portion 14 is provided with an inlet 15 for inserting the medium P. The cutting unit 12 is disposed below the input port 15. The cutting unit 12 crushes the media P input into the input port 15 using fine blades.

[0049] For example, when the subordinate H inserts the medium P into the insertion port 19 provided on the top plate portion 14 of the storage container 16, a series of operations is started. When the medium P is inserted through the insertion port 19 of the storage container 16 , the medium P is moved to the scanner device 11 . The reading unit 111 of the scanner device 11 reads information fixed on the medium P by printing or the like. The acquisition unit 121 of the main control unit 112 converts the information of the medium P read by the reading unit 111 into digital data and acquires it. The transmission control unit 122 of the main control unit 112 executes control to transmit information about the medium P acquired in the form of digital image data to the server 2 via the communication unit 113 . Then, the medium P from which information has been read by the reading unit 111 of the scanner device 11 is moved by the automatic document feeder to a storage unit (not shown) built into the housing unit 17, and is stored there for a certain period of time.

[0050] The information acquisition unit 201 of the server 2 acquires the information (digital image data) transmitted from the storage container 16 via the communication unit 29. The information management unit 202 stores the information acquired by the information acquisition unit 201 in the acquired information DB 40 so that it can be recognized as information on the medium P, thereby managing the information so that it can be read out as information on the medium P.

[0051] The medium P that has been stored for a certain period of time in a storage unit built into the housing unit 17 is taken out of the storage unit and then inserted into an inlet 15 provided in the shredder 20. The medium P is then sent to the cutting unit 12 and shredded.

[0052] When the user K wishes to refer to the information on the medium P, the user K accesses the server 2 via the supervisor terminal 3 to issue an instruction to read out the information.

[0053] When the information reading unit 203 of the server 2 receives an instruction to read information from the supervisor terminal 3, it searches the acquired information DB 40 for information on the medium P. Specifically, the information reading unit 203 acquires a read instruction transmitted from the monitor terminal 3 via the communication unit 29. Then, the information reading unit 203 reads information of the medium P from the acquired information DB 40 via the information management unit 202.

[0054] The display control unit 204 of the server 2 executes control to display the information of the medium P read by the information reading unit 203 on the monitor terminal 3 via the communication unit 29 .

[0055] The monitor terminal 3 acquires information about the medium P in an acquisition unit (not shown) and displays the information on a display (not shown).

[0056] A specific example of the second embodiment has been described above with reference to FIG. In this way, by providing the scanner device 11 and the cutting unit 12 in different housings, a certain period of time may be provided between the reading of the information fixed on the medium P and the shredding of the medium P. This allows, for example, the information fixed on the medium P to be read and the medium P to be stored in the storage container 16, and allows the user K to read the information on the medium P on the monitor terminal 3 and determine whether the medium P should be discarded or not. As a result, the medium P that is determined not to be shredded can be removed from the storage container 16 before being moved to the shredder 20, thereby avoiding shredding. As described above, by setting a certain period between the reading of the information fixed on the medium P and the shredding of the medium P, user K is able to both restore the information and the actual medium P.

[0057] Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within the scope that can achieve the object of the present invention are included in the present invention.

[0058] For example, the hardware configurations shown in FIG. 3, FIG. 4, and FIG. 6 are merely examples for achieving the object of the present invention, and are not particularly limited.

[0059] For example, in the above-mentioned second embodiment, the shredder 1 is described as being configured to include the storage container 16 having the function of reading information fixed to the medium P and the shredder 20 having the function of shredding the medium P, but is not limited to this. In other words, the storage container 16 and the shredder 20 may be provided in the same housing.

[0060] Also, for example, in the above-mentioned second embodiment, the medium P is moved to the crusher 20 after being stored in the storage container 16 for a certain period of time, but the means by which the medium P is moved is not particularly limited. For example, the user K or the like may move the medium P manually, or the medium P may be moved automatically.

[0061] In addition, the functional block diagram shown in Fig. 5 is merely an example and is not particularly limited. In other words, it is sufficient that the information processing device is provided with a function capable of executing the above-mentioned series of processes as a whole, and the type of functional block used to realize this function is not particularly limited to the example of Fig. 5.

[0062] Furthermore, the locations of the functional blocks are not limited to those shown in FIG. 5 and may be arbitrary. Furthermore, one functional block may be configured as a single piece of hardware, a single piece of software, or a combination of both.

[0063] When the processing of each functional block is executed by software, the program constituting the software is installed into a computer or the like from a network or a recording medium. The computer may be a computer built into dedicated hardware, or may be a computer capable of executing various functions by installing various programs, such as a server, a general-purpose smartphone, or a personal computer.

[0064] A recording medium containing such a program is not only composed of removable media that is distributed separately from the device body in order to provide each user with the program, but also composed of a recording medium that is provided to each user in a state in which it is pre-installed in the device body.

[0065] In addition, in the above embodiment, the information fixed to the medium P is output as digital image data, but the present invention is not limited to this. That is, the information on the medium P may be output as text data instead of image data. In this case, the user K may use at least a part of the text data as a keyword to instruct the reading of information on the medium P. Specifically, for example, when the user K wants to read information related to a contract, by inputting the keyword "contract", information on the medium P including the keyword "contract" is searched and extracted from the information on various media P stored in the acquired information DB 40. In this way, by outputting the information on the medium P as text data, there is an advantage that the information on the medium P associated with an arbitrary keyword can be smoothly searched for and extracted.

[0066] However, text data also has a weakness in that the information can be easily rewritten. Specifically, for example, it is easy for a third party to rewrite information about a contract with a customer that has been output as text data, fix it on a new medium, and output it. In this way, when the information on the medium P is output as text data, there is an advantage in that the information can be easily searched and extracted, but there is also a disadvantage in that the information can be easily rewritten.

[0067] In this respect, digital image data has the advantage that the information contained therein is relatively difficult to change, and therefore the information is less likely to be edited. Therefore, if the information fixed on the medium P is important information that cannot be edited, such as information about a contract with a customer, it is preferable for the information fixed on the medium P to be output as digital image data rather than as text data, as this will have a higher evidentiary value as information.

[0068] In other words, the shredder system to which the present invention is applied is sufficient as long as it has the following configuration, and can take various forms. That is, a shredder system according to one aspect of the present invention comprises: In a shredder system including an information processing device (e.g., server 2 in FIG. 2), a shredder (e.g., shredder 1 in FIG. 3) for shredding a medium on which information is fixed (e.g., medium P in FIG. 3), and a scanner device (e.g., scanner device 11 in FIG. 3), The scanner device (e.g., scanner device 11 in FIG. 3) reads information fixed on the medium (e.g., medium P in FIG. 3) at a predetermined timing before the medium is shredded by the shredder (e.g., shredder 1 in FIG. 3), The information processing device includes: An information acquisition unit (e.g., the information acquisition unit 201 in FIG. 5) that acquires the information read by the scanner device (e.g., the scanner device 11 in FIG. 3); an information management unit (e.g., the information management unit 202 in FIG. 5 ) that manages the information acquired by the acquisition unit (e.g., the information acquisition unit 201 in FIG. 5 ) in a restorable state; Equipped with. As a result, the information fixed to the medium (e.g., medium P in FIG. 3) is read by a scanner device (e.g., scanner device 11 in FIG. 3) at a predetermined timing before the medium (e.g., medium P in FIG. 3) is shredded by the shredder (e.g., shredder 1 in FIG. 3), acquired by information acquisition means of the information processing device (e.g., information acquisition unit 201 in FIG. 5), and managed in a restorable state by information management means (e.g., information management unit 202 in FIG. 5). In other words, because the information fixed to the medium is acquired before the medium is shredded and managed in a restorable state, it becomes possible to prevent the loss of information.
