  The proofreading support processing unit 341 receives the image data subjected to character recognition and the character-recognized character string from the image forming apparatus 1 via the communication unit 33, and displays the proofreading screen G80 shown in the figure on the touch panel 31. . Then, the proofreading support processing unit 341 corrects the error of the character string recognized as a character correctly according to the proofreading operation by the proofreading user through the proofreading screen G80, and forms an image of the corrected character string via the communication unit 33. Transmit to device 1.

  Next, with reference to FIG. 3, the flow of calibration work using the operation panel 11 of the image forming apparatus 1 will be described.

  When the calibration user logs in via the authentication screen displayed on the touch panel 111 (step s11) and a document reading instruction is issued via the operation panel 11 (step s12), the control unit 17 reads from the storage unit 13. Character area information 132 that is a character recognition target is acquired (step s13).

  Subsequently, the control unit 17 causes the document reading unit 12 to scan the document (step s14). When image data of each page of the document is generated by scanning by the document reading unit 12, the control unit 17 functions as a character extraction unit 171. The character extraction unit 171 performs character recognition of the character area set in the character area information 132 with respect to the image data of each page of the document generated by the document reading unit 12, and extracts a character string from the character area ( Step s15). The image data of each page of the document scanned by the document reading unit 12 and the character string of each page of the document extracted by the character extraction unit 171 are stored in the storage unit 13 in association with each other.

  Subsequently, the calibration processing unit 173 enters a calibration mode using the operation panel 11 (step s16), and the screen generation unit 172 generates a calibration screen G80 shown in FIG.

  The calibration screen G80 is provided with a display area A81 that displays the image data subjected to character recognition and the character string extracted from the character area A82 in the image data side by side. Further, the calibration screen G80 is used to correct the characters of the character string displayed in the display area A81 correctly, and to update the image data and character strings in the display area A81 to those of the next page. A next page button B82 and a calibration end button B83 for ending the calibration work are provided. When correcting the erroneously recognized character, the calibration user touches the character to be corrected from the character string displayed in the display area A81 to designate it as a calibration target character, and presses the calibration button B81. Then, the screen generation unit 172 generates a calibration input screen G81 for accepting correct character input and displays it on the touch panel 111, as shown in FIG.

  The proofreading input screen G81 is provided with an input field A83 for inputting a correct character for the proofreading target character. In FIG. 5, the character to be proofread is shown by highlighting (solid black in the figure). When the calibration user inputs a correct character in the input field A83 using the software keyboard or the operation unit 112 and presses the OK button B84, the calibration processing unit 173 inputs the calibration target character displayed in the display area A81. Replace with the character entered in column A83. As a result, the erroneously recognized character can be corrected to a correct character. When the next page button B82 is pressed through the calibration input screen G81, the screen generation unit updates the image data and character string of the current page displayed in the display area A81 to the image data and character string of the next page. The corrected calibration screen G80 is generated and displayed on the touch panel 111. Further, when the next page button B82 is pressed, the proofreading processing unit 173 stores the character string displayed in the display area A81 as a post-calibration character string in a buffer or the like.

  When the calibration end button B83 is pressed (step s17), the calibration processing unit 173 displays the character string of the current page displayed in the display area A81 and the post-calibration character string stored in the buffer before the current page. Are reflected in the character strings of the corresponding pages stored in the storage unit 13, respectively. Then, the proofreading processing unit 173 stores the reflected character string of each page as post-proofreading data in association with the image data of each page of the document (step s18), and ends this processing.

  On the other hand, if the specific job detection unit 174 detects a specific job (Yes in step s19) before the calibration end button B83 is pressed (No in step s17), the screen generation unit notifies the operation schedule notification shown in FIG. The screen G90 is generated and displayed on the touch panel 111 to notify the calibration work user that there is an operation plan on the operation panel 11 by the specific job (step s20). If no specific job is detected by the specific job detection unit 174 (No in step s19), the process returns to step s16, and the calibration processing unit 173 continues to accept a calibration operation from the operation panel 11.

  The operation schedule notification screen G90 includes an operation schedule notification such as “Another user is going to use the image forming apparatus 1. Do you want to save work contents and operate on the mobile terminal 3?” An address designation field A91 for designating the mail address of the terminal 3, an Yes button B91 for instructing an operation on the portable terminal 3, and a No button B92 for ignoring the operation schedule notification are provided. When the user information 131 includes the mail address of the proofreading user, the operation schedule notification screen G90 is displayed with the mail address of the proofreading user entered in the address designation field A91.

  When the Yes button B91 on the operation schedule notification screen G90 is pressed, the calibration processing unit 173 determines that an operation on the portable terminal 3 has been instructed (Yes in step s21). In this case, the proofreading processing unit 173 finally calibrates the character string displayed in the display area A81 of the calibration screen G80 and each page stored in the buffer (just before displaying the operation schedule notification screen G90). The character string is reflected in the character string of the corresponding page stored in the storage unit 13 and stored as proofreading data including the page information of the manuscript finally displayed in the display area A81 of the calibration screen G80. 13 (step s22).

  Subsequently, the calibration processing unit 173 generates and transmits an e-mail in which a URL (Uniform Resource Locator) for access is described in the e-mail address specified on the operation schedule notification screen G90 via the communication unit 16 (Step S1). s23), the process ends. The URL for access is a URL for allowing the calibration processing unit 173 to enter the calibration mode using the mobile terminal 3 so that the calibration operation from the mobile terminal 3 can be started. Associated with data to be accessible. As described above, when the specific job detection unit 174 detects a specific job based on the print job received from the external terminal 2, the calibration work user has an operation plan on the operation panel 11 from the specific job by the operation schedule notification screen G 90. Therefore, the calibration work user can calm down and finish the calibration work by the operation panel 11. In addition, since the calibration work by the operation panel 11 is finished before the specific job creation user actually arrives at the image forming apparatus 1 and the calibration operation can be taken over by the portable terminal 3, the specific job creation user and the operation panel 11 are in contact with each other. Can be avoided.

  On the other hand, when the No button B92 on the operation schedule notification screen G90 is pressed, the calibration processing unit 173 determines that it is instructed not to operate the mobile terminal 3 (No in step s21), and the process proceeds to step s16. To return. In this case, the calibration work user can continue the calibration work using the operation panel 11 until the specific job creation user actually comes to the image forming apparatus 1.

  Next, the flow of calibration work using the mobile terminal 3 will be described with reference to FIG. In FIG. 7, for each state of the image forming apparatus 1 and the portable terminal 3, a case where processing is on standby is indicated by a dotted line, and a case where processing is being executed is indicated by a solid line.

  When the control unit 34 of the portable terminal 3 receives the mail describing the URL for access from the image forming apparatus 1 via the communication unit 33 (step s30), the control unit 34 reads the calibration support APP 321 stored in the storage unit 32. The calibration support APP 321 is activated in the RAM and functions as the calibration support processing unit 341.

  When the proofreading user accesses the access URL described in the e-mail via the touch panel 31 (step s31), the proofreading support processing unit 341 transmits an access request to the image forming apparatus 1 via the communication unit 33 ( Step s32). Subsequently, when the calibration processing unit 173 of the image forming apparatus 1 receives the access request from the portable terminal 3, it transmits an authentication request to the portable terminal 3 (step s33).

  When receiving an authentication request from the image forming apparatus 1 via the communication unit 33, the calibration support processing unit 341 displays an authentication screen for accepting input of a user ID and a password on the touch panel 31 (step s34). When the calibration work user inputs his / her user ID and password registered in the user information 131 via the touch panel 31 (step s35), the calibration support processing unit 341 passes the input user ID and password via the communication unit 33. It transmits to the image forming apparatus 1 (step s36).

  The calibration processing unit 173 of the image forming apparatus 1 logs in the calibration work user when the user ID and password received from the portable terminal 3 via the communication unit 16 match the user ID and password registered in the user information 131. Accept (step s37). Subsequently, the calibration processing unit 173 enters a calibration mode using the mobile terminal 3 (step s38), and the image of the page that was last calibrated based on the calibration intermediate data of the calibration work user stored in the storage unit 13 is displayed. Data and a character string are transmitted to the portable terminal 3 via the communication part 33 (step s39).

  The calibration support processing unit 341 of the portable terminal 3 displays on the touch panel 31 the calibration screen G80 in which the image data and the character string received via the communication unit 33 are displayed in the display area A81 (step s40). As a result, the calibration user can perform the calibration operation on the touch panel 31 of the portable terminal 3 from the continuation of the calibration operation performed on the operation panel 11.

  When the calibration user designates the character to be calibrated and presses the calibration button B81 (Yes in step s41), the calibration support processing unit 341 displays the calibration input screen G81 on the touch panel 31, and the calibration work user inputs the input field A83. The character to be calibrated displayed in the display area A81 is corrected by the character input to (step s42), and the process returns to step s39.

  When the next page button B82 is pressed instead of the calibration button B81 (Yes in step s43), the calibration support processing unit 341 uses the character string displayed in the display area A81 of the calibration screen G80 as the post-calibration character string as the next page. Along with the acquisition request, it is transmitted to the image forming apparatus 1 via the communication unit 33 (step s44).

  When the proofreading processing unit 173 of the image forming apparatus 1 receives the post-calibration character string and the next page acquisition request from the portable terminal 3 via the communication unit 16, the proofreading processing unit 173 transmits the character string of the corresponding page stored in the storage unit 13 to the portable terminal. 3 is corrected to the post-proofreading character string received from step 3 (step s45). Subsequently, the calibration processing unit 173 acquires the image data and character string of the next page from the storage unit 13 and transmits them to the portable terminal 3 via the communication unit 16 (step s46).

  In this way, the image forming apparatus 1 transmits image data and a character string for each page of the document to the mobile terminal 3, and the mobile terminal 3 sends a post-calibration character string and a next page acquisition request or a calibration end notification described later. By configuring to transmit to the image forming apparatus 1, it is possible to reduce the influence on the communication speed and communication amount of the mobile terminal 3. Note that the calibration support processing unit 341 may transmit only the next page acquisition request to the image forming apparatus 1 when the next page button B82 is pressed without pressing the calibration button B81. Then, when only the next page acquisition request is received, the proofreading processing unit 173 may determine the character string of the corresponding page stored in the storage unit 13 as the post-calibration character string.

  When the calibration support processing unit 341 of the mobile terminal 3 receives the image data and the character string of the next page from the image forming apparatus 1 via the communication unit 33, the current page is set so as not to affect the storage capacity of the mobile terminal 3. Are deleted (step s47), and the process returns to step s40. In this case, the display area A81 of the calibration screen G80 is updated with the image data and character string of the next page received from the image forming apparatus 1.

  On the other hand, when not the calibration button B81 but the next page button B82 and the calibration end button B83 is pressed (Yes in step s48), the calibration support processing unit 341 is displayed in the display area A81 of the calibration screen G80. The character string is transmitted as a post-calibration character string to the image forming apparatus 1 via the communication unit 33 together with a calibration end notification (step s49). Also in this case, the calibration support processing unit 341 notifies the calibration end when the calibration end button B83 is pressed without pressing the calibration button B81 for the page displayed in the display area A81 of the calibration screen G80. May be transmitted to the image forming apparatus 1. If the calibration end button B83 is not pressed, the process returns to step s41.

  Subsequently, when the calibration processing unit 173 of the image forming apparatus 1 receives the post-calibration character string and the calibration end notification from the portable terminal 3 via the communication unit 16, the calibration processing unit 173 displays the character string of the corresponding page stored in the storage unit 13. The corrected character string received from the portable terminal 3 is corrected (step s50). Subsequently, the calibration processing unit 173 stores the character string of each page of the document stored in the storage unit 13 as post-calibration data in association with the image data of each page of the document (step s51). Subsequently, the calibration processing unit 173 transmits a storage completion notification indicating that the storage of the post-calibration data is completed to the mobile terminal 3 via the communication unit 16 (step s52).

  When the calibration support processing unit 341 of the portable terminal 3 receives the storage completion notification from the image forming apparatus 1 via the communication unit 33, the remaining image data and character string, that is, finally displayed on the display area A 81 of the calibration screen G 80. The processed image data and character string are erased (step s53), and this process ends. The calibration processing unit 173 may delete the stored image data and character string even when communication with the image forming apparatus 1 has timed out in the communication unit 33.

  As described above, the image forming apparatus 1 according to the present embodiment is an image forming apparatus 1 that executes a received print job, and reads a document one page at a time to acquire image data of each page; A character extraction unit 171 that recognizes characters of image data of each page and extracts a character string, an operation panel 11 that displays image data and a character string, and receives a calibration operation on the character string, and an operation panel 11 are used. The calibration processing unit 173 has a calibration mode and a calibration mode using the portable terminal 3 and corrects a character string based on a calibration operation by the operation panel 11 or a calibration operation by the portable terminal 3 and a specific operation on the operation panel 11 A specific job detection unit 174 for detecting a print job as a specific job as a specific job, and a specific job detection in a calibration mode using the operation panel 11 A screen for generating an operation schedule notification screen G90 for notifying the operation schedule of the operation panel 11 by the specific job and confirming whether or not to operate on the mobile terminal 3 when the specific job is detected in 174 and displaying it on the operation panel 11 A generation unit 172 and a communication unit 16 that communicates with the mobile terminal 3 are provided. The calibration processing unit 173 uses the mobile terminal 3 when an operation by the mobile terminal 3 is instructed via the operation schedule notification screen G90. The calibration mode is set, image data and a character string are transmitted to the portable terminal 3 via the communication unit 16, and the character string is corrected based on a calibration operation from the portable terminal 3.

  Accordingly, when the calibration work user is performing the calibration work on the operation panel 11, if there is another user who uses the operation panel 11, the operation schedule notification screen G90 is notified. Therefore, the proofreading user can take over the proofreading work to the portable terminal 3 without panicking before other users come to the image forming apparatus 1, and can perform the proofreading work calmly.

  Actually, it often takes time for the specific job creation user to come to the front of the image forming apparatus 1 and operate the operation panel 11 after the specific job detection unit 174 detects the specific job. Therefore, as shown in FIG. 8, the specific job history storage unit 133 stores the reception time of the specific job by the communication unit 16 and the specific operation time when the specific operation is received by the operation panel 11 for each specific job creation user. The unit 13 may function. In this case, the screen generation unit 172 is based on the difference time between the reception time and the specific operation time stored in the specific job history storage unit 133 for the specific job creation user of the specific job detected by the specific job detection unit 174. An operation schedule notification screen G90 that notifies the operation schedule may be generated and displayed on the operation panel 11. According to this, the calibration work user can round up the calibration work by the operation panel 11 with good timing. Note that the screen generation unit 172 may calculate a difference time between the most recent reception time and the specific operation time stored in the specific job history storage unit 133, or a plurality of reception times and a plurality of specific operation times. You may calculate the difference time which smoothed each difference time.

  For example, the screen generation unit 172 adds the difference time between the reception time stored in the specific job history storage unit 133 and the specific operation time to the reception time of the specific job whose current time is detected by the specific job detection unit 174. The operation schedule notification screen G90 may be displayed on the operation panel 11 at a timing before a specific time.
