DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and description thereof will not be repeated.

[0011] <Embodiment 1> An image reading system 1 according to the first embodiment will be described with reference to Figs. 1 to 8. Fig. 1 is a block diagram showing an example of the overall configuration of the image reading system 1 according to the first embodiment. The image reading system 1 includes at least one or more mobile terminals 2 and one or more image reading devices 3. In addition to the mobile terminal 2 and the image reading device 3, the image reading system 1 may also include an authentication server 4 or a payment server 5.

[0012] The portable terminal 2 and the image reading device 3 can be connected to each other through short-range wireless communication. The short-range wireless communication is, for example, Bluetooth (registered trademark), a wireless LAN (Local Area Network), or a near field communication (NFC).

[0013] The mobile terminal 2, the image reading device 3, the authentication server 4, and the payment server 5 can be connected via a network 6. The network 6 is a LAN, the Internet, or the like.

[0014] The mobile terminal 2 is a smartphone, a tablet, a personal computer, etc. The image reading device 3 has at least an image reading function of reading a document and generating image data. The image reading device 3 may be an image reading device with an image forming function, which is provided with an image forming function of forming an image on a sheet. The image reading device 3 may also be a multifunction device that has an image forming function, a function for sending and receiving facsimile, a function for sending e-mail, etc. in addition to the image reading function.

[0015] The authentication server 4 has a function of authenticating a user who owns the portable terminal 2. The authentication server 4 may also manage the authority regarding functions of the image reading device 3 that can be used by the user who owns the portable terminal 2.

[0016] The settlement server 5 has a function of settling the fee when a user who owns the mobile terminal 2 uses the image reading device 3.

[0017] 2 is a block diagram showing an example of the configuration of the mobile terminal 2 according to embodiment 1. The mobile terminal 2 includes a communication unit 21, a storage unit 22, a display unit 25, an input unit 26, and a control unit 27.

[0018] The communication unit 21 performs short-distance wireless communication with the image reading device 3. The communication unit 21 also communicates with the authentication server 4 and the payment server 5 via the network 6 as necessary. The communication unit 21 is a communication circuit compatible with various communication standards.

[0019] The storage unit 22 stores various data such as mobile terminal identification information 23 and a portrait scan setting profile 24. The storage unit 22 is, for example, a storage medium such as a hard disk drive (HDD), a solid state drive (SSD), a random access memory (RAM), or a read only memory (ROM).

[0020] The mobile terminal identification information 23 is information for identifying the mobile terminal 2. The mobile terminal identification information 23 is, for example, a passcode used for pairing of Bluetooth (registered trademark).

[0021] The portrait scan setting profile 24 is an example of a scan setting profile registered by a user who owns the mobile terminal 2.

[0022] The display unit 25 is a display. The input unit 26 is a physical button, a touch panel, or the like. The touch panel may be attached to the surface of the display that is the display unit 25. In the following, it is assumed that the display unit 25 and the input unit 26 are integrated into one structure, that is, the touch panel is attached to the surface of the display.

[0023] The control unit 27 controls the operation of each function of the portable terminal 2. For example, when the communication unit 21 establishes a connection for short-distance wireless communication with the image reading device 3, the control unit 27 starts an application program installed in the portable terminal 2. Then, the control unit 27 causes data to be transmitted and received between the communication unit 21 and the image reading device 3 in accordance with the application program. Also, for example, the control unit 27 causes the user to perform an operation for registering a scan setting profile in accordance with the application program.

[0024] FIG. 3 is a diagram showing an example of a scan setting profile registration screen 25a displayed by the mobile terminal 2 according to the first embodiment. When the user performs a scan setting profile registration operation, the control unit 27 causes the display unit 25 to display the scan setting profile registration screen 25a. The scan setting profile registration screen 25a displays setting items such as document orientation, resolution, color mode, document type, file format, and back-bleed prevention. For example, the user operates the setting item "document orientation" to change the setting content to "portrait" or "landscape". The document orientation is the orientation of the document set by the user on the document feeder of the image reading device 3 or on the document placement surface such as the platen glass. In the scan setting profile registration screen 25a, the document orientation is set to portrait, the resolution is set to 600×600 dpi, the color mode is set to full color, the document type is set to document, the file format of the image data read from the document is set to PDF, and the back-bleed prevention function is set to OFF. In addition, when the user operates the "other setting items" button, the control unit 27 causes other setting items not displayed on the scan setting profile registration screen 25a to be displayed. When the input unit 26 accepts a user operation on the “Register” button, the control unit 27 stores the setting items and setting contents shown on the scan setting profile registration screen 25a in the memory unit 22 as the scan setting profile 24 for portrait orientation.

[0025] The control unit 27 includes, for example, a processor such as a CPU (Central Processing Unit) and memories such as a ROM and a RAM. For example, the control unit 27 executes various processes defined in an application program by causing the processor to execute the application program pre-stored in the memory.

[0026] 4 is a block diagram showing an example of the configuration of the image reading device 3 according to embodiment 1. The image reading device 3 includes a communication unit 31, a storage unit 32, a display unit 35, an input unit 36, a control unit 37, an image reading unit 38, and an OCR (Optical Character Recognition) processing unit 39.

[0027] The communication unit 31 performs short-distance wireless communication with the mobile terminal 2. Furthermore, the communication unit 31 communicates with the authentication server 4 and the payment server 5 via the network 6 as necessary. The communication unit 31 is a communication circuit compatible with various communication standards.

[0028] The storage unit 32 stores various data such as mobile terminal identification information 33 and a landscape scan setting profile 34. The storage unit 32 is, for example, a storage medium such as an HDD, an SSD, a RAM, or a ROM.

[0029] The portable terminal identification information 33 is information for identifying the portable terminal 2. The portable terminal identification information 33 is, for example, a passcode used for pairing of Bluetooth (registered trademark). When the portable terminal 2 and the image reading device 3 are already paired, the portable terminal identification information 23 stored in the storage unit 22 of the portable terminal 2 and the portable terminal identification information 33 stored in the storage unit 32 of the image reading device 3 are the same.

[0030] The horizontal scan setting profile 34 is an example of a scan setting profile registered in advance in the image reading device 3. The horizontal scan setting profile 34 may be registered in the past by a user who owns the mobile terminal 2 by operating the input unit 36, or may be an initial profile registered in advance by a manufacturer or the like. Note that no scan setting profile may be stored in the storage unit 32, and both the vertical scan setting profile 24 and the horizontal scan setting profile 34 may be stored in the storage unit 22 of the mobile terminal 2.

[0031] The display unit 35 is a display. The input unit 36 ​​is a physical button, a touch panel, or the like. The touch panel may be attached to the surface of the display that is the display unit 35. In the following, it is assumed that the display unit 35 and the input unit 36 ​​are integrated into one unit.

[0032] The control unit 37 controls the operation of each function of the image reading device 3. For example, the control unit 37 acquires the vertical scan setting profile 24 registered in the mobile terminal 2 or the horizontal scan setting profile 34 stored in the storage unit 32 according to the orientation of the document set in the image reading unit 38 by the user who owns the mobile terminal 2. When acquiring the vertical scan setting profile 24 registered in the mobile terminal 2, the control unit 37 acquires the vertical scan setting profile 24 from the mobile terminal 2 via the communication unit 31 and notifies the image reading unit 38 of the acquired vertical scan setting profile 24. The control unit 37 may also request the authentication server 4 to authenticate the user who owns the mobile terminal 2. The control unit 37 may also request the payment server 5 to settle the price when the user who owns the mobile terminal 2 uses the image reading device 3.

[0033] The image reading unit 38 uses the scan setting profile notified by the control unit 37 to perform image reading processing on the document set in the document feeder or on the document placement surface, and generates image data.

[0034] The OCR processing unit 39 performs OCR processing on the image data generated by the image reading unit 38. Based on the result of the OCR processing, the OCR processing unit 39 determines whether the quality of the image data is equal to or higher than a predetermined quality. The OCR processing unit 39 determines the quality of the image data based on a character recognition rate, etc. If the character recognition rate of the image data is equal to or higher than a predetermined threshold, the OCR processing unit 39 determines that the quality of the image data is equal to or higher than the predetermined quality.

[0035] The control unit 37 and the OCR processing unit 39 each have, for example, a processor such as a CPU and memories such as a ROM and a RAM. For example, the control unit 37 and the OCR processing unit 39 each perform various processes defined by a computer program by causing the processor to execute a computer program previously stored in the memory.

[0036] 5 is a flowchart showing an example of the operation of the image reading device 3 according to embodiment 1. The image reading device 3 repeats the operation shown in the flowchart of FIG.

[0037] Here, it is assumed that the user, carrying the portable terminal 2, moves into the short-distance wireless communication range of the image reading device 3. The communication unit 31 establishes a connection with the communication unit 21 of the portable terminal 2 that has entered the short-distance wireless communication range. When the short-distance wireless communication connection is established, the control unit 27 of the portable terminal 2 automatically starts the installed application program. Then, in accordance with the application program, the control unit 27 transmits the portable terminal identification information 23 stored in the storage unit 22 to the image reading device 3 via the communication unit 21. The communication unit 31 of the image reading device 3 receives the portable terminal identification information 23 transmitted by the portable terminal 2.

[0038] In step S1, the control unit 37 checks whether or not portable terminal identification information 33 that matches the portable terminal identification information 23 received from the portable terminal 2 exists in the storage unit 32. If portable terminal identification information 33 that matches the portable terminal identification information 23 exists in the storage unit 32 (step S1; Yes), that is, if a registered portable terminal 2 exists within the short-range wireless communication range of the image reading device 3, the processing of the control unit 37 proceeds to step S2. If portable terminal identification information 33 that matches the portable terminal identification information 23 does not exist in the storage unit 32 (step S1; No), that is, if a registered portable terminal 2 does not exist within the short-range wireless communication range of the image reading device 3, the processing of the control unit 37 ends.

[0039] If an unregistered mobile terminal 2 is present within the short-distance wireless communication range (step S1; No), the control unit 37 may perform a registration process for this mobile terminal 2 and then perform the process of step S2.

[0040] In step S2, the control unit 37 authenticates the user who possesses the registered mobile terminal 2. For example, the control unit 37 notifies the authentication server 4 of information capable of identifying the user, such as the mobile terminal identification information 33, via the communication unit 31, and requests authentication of the user who possesses the mobile terminal 2. The control unit 37 receives a result of authentication of the user from the authentication server 4 via the communication unit 31. In addition to the result of authentication of the user, the control unit 37 may also receive from the authentication server 4 via the communication unit 31 information on whether the user has authority to use the image reading function of the image reading device 3. If the authentication of the user is successful or if the user has authority to use the image reading function (step S2; Yes), the process of the control unit 37 proceeds to step S3. If the authentication of the user is unsuccessful or if the user does not have authority to use the image reading function (step S2; No), the process of the control unit 37 ends.

[0041] In the above example, user authentication is performed by the authentication server 4, but it may be performed by the image reading device 3. For example, user identification information is registered in advance in the storage unit 32 of the image reading device 3, and in step S2, the control unit 37 reads the user identification information from an IC card carried by the user and determines whether the read user identification information matches the registered user identification information. Alternatively, the control unit 37 may determine whether the user identification information input by the user to the input unit 36 ​​matches the registered user identification information.

[0042] The user who has been successfully authenticated sets the document on the document feeder or document placement table of the image reading device 3. At this time, the control unit 37 may generate a screen that guides the user to set the document and display it on the display unit 35.

[0043] In step S3, the control unit 37 instructs the image reading unit 38 to determine the orientation of the document. Upon receiving the instruction from the control unit 37, the image reading unit 38 determines the orientation of the document that has been set. The image reading unit 38 notifies the control unit 37 of the result of determining the orientation of the document.

[0044] In step S4, the control unit 37 acquires from the mobile terminal 2 via the communication unit 31 a scan setting profile that corresponds to the orientation of the document notified by the image reading unit .

[0045] For example, when the orientation of the document notified by the image reading unit 38 is portrait, the control unit 37 requests the portrait-use scan setting profile 24 from the mobile terminal 2 via the communication unit 31. In response to this request, the control unit 27 of the mobile terminal 2 obtains the portrait-use scan setting profile 24 stored in the storage unit 22, and transmits it to the image reading device 3 via the communication unit 21.

[0046] Furthermore, for example, when the orientation of the document notified from the image reading unit 38 is landscape, the control unit 37 requests the landscape scan setting profile 34 from the mobile terminal 2 via the communication unit 31. In response to this request, the control unit 27 of the mobile terminal 2 obtains the landscape scan setting profile 34 stored in the storage unit 22, and transmits it to the image reading device 3 via the communication unit 21.

[0047] When the portrait scan setting profile 24 or the landscape scan setting profile 34 requested by the image reading device 3 does not exist in the storage unit 22, the control unit 27 transmits a response to that effect to the image reading device 3 via the communication unit 21. In the configuration example of FIG. 2, the landscape scan setting profile 34 does not exist in the storage unit 22. Therefore, when the landscape scan setting profile 34 is requested by the image reading device 3, the control unit 27 transmits a response to the image reading device 3 to the effect that the landscape scan setting profile 34 does not exist.

[0048] Alternatively, the control unit 37 may determine whether to acquire the scan setting profile from the mobile terminal 2 based on the orientation of the document notified by the image reading unit 38. In the configuration example of FIG. 4, when the orientation of the document is portrait, the control unit 37 determines to acquire the scan setting profile from the mobile terminal 2 because the portrait-use scan setting profile 24 does not exist in the storage unit 32. Then, the control unit 37 requests the portrait-use scan setting profile 24 from the mobile terminal 2 via the communication unit 31. In response to this request, the mobile terminal 2 transmits the portrait-use scan setting profile 24 to the image reading device 3. On the other hand, when the portrait-use scan setting profile 24 exists in the storage unit 32, the control unit 37 determines to acquire the portrait-use scan setting profile 24 from the storage unit 32.

[0049] If the vertical scan setting profile 24 does not exist in either the memory unit 22 of the mobile terminal 2 or the memory unit 32 of the image reading device 3, the control unit 37 causes the user to register a scan setting profile. In this case, for example, the control unit 37 generates a registration screen such as a scan setting profile registration screen 25a (FIG. 3) and displays it on the display unit 35. The input unit 36 ​​accepts a user operation on the registration screen. The control unit 37 generates the vertical scan setting profile 24 based on the user operation accepted by the input unit 36.

[0050] In step S5, the control unit 37 notifies the image reading unit 38 of the scan setting profile acquired in step S4. The image reading unit 38 performs image reading processing on the set document using the scan setting profile notified from the control unit 37, and generates image data.

[0051] In step S5, the control unit 37 may first generate a scan screen showing the settings of the scan setting profile and display it on the display unit 35. FIG. 6 is a diagram showing an example of a scan screen 35a displayed by the image reading device 3 according to the first embodiment. The control unit 37 generates the scan screen 35a using the vertical scan setting profile 24 acquired from the mobile terminal 2. The user checks the settings of each setting item before the image reading process, and if there is no problem with the settings, operates the "start" button. The input unit 36 ​​accepts a user operation on the "start" button. The control unit 37 instructs the image reading unit 38 to start the image reading process according to the user operation accepted by the input unit 36.

[0052] When the user wishes to change the settings displayed on the scan screen 35a, the user performs an operation to change the settings. The input unit 36 ​​accepts the user operation to change the settings. The control unit 37 changes the portrait-use scan setting profile 24 in accordance with the user operation accepted by the input unit 36. The control unit 37 may transmit the changed portrait-use scan setting profile 24 to the mobile device 2 via the communication unit 31, and update the portrait-use scan setting profile 24 registered in the mobile device 2 to the changed portrait-use scan setting profile 24.

[0053] In step S6, the control unit 37 receives image data obtained by reading the document from the image reading unit 38, and outputs the image data to the OCR processing unit 39. Upon receiving the image data from the control unit 37, the OCR processing unit 39 performs OCR processing on the image data. Based on the result of the OCR processing, the OCR processing unit 39 determines whether the quality of the image data is equal to or higher than a predetermined quality. The OCR processing unit 39 notifies the control unit 37 of the quality determination result.

[0054] In step S7, the control unit 37 receives the quality judgment result of the image data from the OCR processing unit 39. If the quality of the image data is equal to or higher than the predetermined quality (step S7; Yes), the process of the control unit 37 proceeds to step S8. If the quality of the image data is lower than the predetermined quality (step S7; No), the process of the control unit 37 proceeds to step S9.

[0055] Note that in step S7, the control unit 37 may generate a review screen for the image data and display it on the control unit 37. Fig. 7 is a diagram showing an example of a review screen 35b displayed by the image reading device 3 according to the first embodiment. The review screen 35b displays the image data generated by the image reading unit 38 as a scan result. Also, an "OK" button, a "Retry" button, and a "Review only when an error is detected" button are displayed on the review screen 35b.

[0056] If the user operates the "OK" button, the process of the control unit 37 proceeds to step S8. If the user operates the "Retry" button, the process of the control unit 37 proceeds to step S9. If the user operates the "Review only when an error is detected" button, the control unit 37 displays the review screen 35b only if the quality of the image data is below a predetermined quality from the next image reading process onwards. If the quality of the image data is equal to or higher than the predetermined quality, the control unit 37 performs the process of step S8 without displaying the review screen 35b.

[0057] In step S8, the control unit 37 transmits the image data generated in step S5 to the mobile terminal 2 via the communication unit 31.

[0058] In step S9, the control unit 37 generates a change screen for the scan setting profile acquired in step S4. The control unit 37 causes the display unit 35 to display the generated change screen. FIG. 8 is a diagram showing an example of a scan setting profile change screen 35c displayed by the image reading device 3 according to the first embodiment. While viewing the scan setting profile change screen 35c displayed on the display unit 35, the user performs an operation on the input unit 36 ​​to change the setting contents of each setting item. The input unit 36 ​​accepts the operation to change the setting contents. The control unit 37 changes the scan setting profile in accordance with the operation accepted by the input unit 36, and notifies the image reading unit 38 of the changed scan setting profile. In the subsequent step S5, the image reading unit 38 performs the image reading process again using the changed scan setting profile.

[0059] After transmitting the image data to the portable terminal 2, the control unit 37 may request the payment server 5 to process the payment for the image reading process. Alternatively, the control unit 37 may transmit information on the fee for the image reading process in addition to the image data to the portable terminal 2. In this case, the control unit 27 of the portable terminal 2 may request the payment server 5 to process the payment for the fee after receiving the image data. The timing of the payment is not limited to after the image data is transmitted.

[0060] As described above with reference to FIG. 1 to FIG. 8, the image reading device 3 includes the storage unit 32, the communication unit 31, the control unit 37, and the image reading unit 38. The storage unit 32 stores the mobile terminal identification information 33. The communication unit 31 performs short-distance wireless communication with the mobile terminal 2 whose mobile terminal identification information 33 is stored in the storage unit 32, and transmits and receives data to and from the mobile terminal 2 via an application program installed in the mobile terminal 2 that starts when the connection of the short-distance wireless communication is established. The control unit 37 causes the communication unit 31 to receive the scan setting profile registered in the mobile terminal 2. The image reading unit 38 reads a document according to the scan setting profile and generates image data. In this way, the image reading device 3 is configured to automatically obtain the scan setting profile from the mobile terminal 2 with which the connection of the short-distance wireless communication is established, and read the document. Therefore, the image reading device 3 can save the user the trouble of selecting the image reading device 3 from the search list displayed on the display unit 25 of the mobile terminal 2 and the trouble of setting the scan setting profile for the image reading device 3.

[0061] Furthermore, the control unit 37 causes the image data generated by the image reading unit 38 to be transmitted from the communication unit 31 to the portable terminal 2. In this manner, the image reading device 3 is configured to automatically transmit the read image data to the portable terminal 2 with which a short-range wireless communication connection has been established. Therefore, the image reading device 3 can save the user the trouble of selecting the portable terminal 2 to which the data is to be transmitted from the operation screen displayed on the display unit 35 of the image reading device 3.

[0062] The portrait scan setting profile 24 and the landscape scan setting profile 34 may be configured to be registered in the portable terminal 2. In this configuration, the image reading unit 38 determines whether the document is in portrait or landscape orientation. Based on the determination result of the image reading unit 38, the control unit 37 causes the communication unit 31 to receive the portrait scan setting profile 24 or the landscape scan setting profile 34 registered in the portable terminal 2. In this manner, the image reading device 3 is configured to automatically obtain the scan setting profile according to the orientation of the document from the portable terminal 2. Therefore, the image reading device 3 can save the user the trouble of setting a scan setting profile in the image reading device 3.

[0063] The vertical scan setting profile 24 may be registered in one of the mobile terminal 2 and the image reading device 3, and the horizontal scan setting profile 34 may be registered in the other of the mobile terminal 2 and the image reading device 3. In this case, the image reading unit 38 determines whether the document is vertical or horizontal. The control unit 37 determines whether to receive the scan setting profile from the mobile terminal 2 based on the determination result of the image reading unit 38, and when it is determined that the scan setting profile is to be received from the mobile terminal 2, the control unit 37 causes the communication unit 31 to receive the scan setting profile registered in the mobile terminal 2. In this way, the image reading device 3 automatically acquires the scan setting profile according to the orientation of the document from the mobile terminal 2. Also, when it is determined that the image reading device 3 does not acquire the scan setting profile from the mobile terminal 2, it is sufficient to use the scan setting profile registered in the image reading device 3. Therefore, the image reading device 3 can save the user the trouble of setting the scan setting profile to the image reading device 3.

[0064] The image reading device 3 also includes a display unit 35. The display unit 35 displays the image data generated by the image reading unit 38. This configuration allows the user to confirm whether or not reading has been successful in the desired state.

[0065] The image reading device 3 also includes an OCR processing unit 39. The OCR processing unit 39 performs OCR processing on the image data generated by the image reading unit 38 and determines whether the quality of the image data is equal to or higher than a predetermined quality. If the quality of the image data is lower than the predetermined quality, the display unit 35 displays an instruction to the user to change the scan setting profile. With this configuration, the user can confirm whether reading has been successful in the desired state.

[0066] The embodiments of the present invention have been described above with reference to the drawings (FIGS. 1 to 8). However, the present invention is not limited to the above embodiments, and can be embodied in various forms without departing from the spirit of the present invention. Variation 1 will be described below.
