<1-1. Basic configuration>
The present invention can be implemented in various forms as will be described in detail in “2. Detailed Description of Embodiments” as an example. First, a basic configuration of an information processing system according to an embodiment of the present invention will be described with reference to FIG. As shown in FIG. 1, the information processing system according to the present embodiment includes an image recognition server 10, a multifunction device 20, and a communication network 22.

[1-1-1. Image recognition server 10]
The image recognition server 10 is an example of an information processing apparatus according to the present invention. The image recognition server 10 is an apparatus for registering and managing electronic data obtained by scanning a form in a database. In the following, an example in which the image recognition server 10 is applied to a production management system and electronic data of a quality record form in the manufacturing industry is managed will be described.

  In addition, the image recognition server 10 can transmit and receive information to and from the multifunction device 20 via, for example, a communication network 22 described later. For example, the image recognition server 10 receives the scan data of the quality record form from the multifunction device 20.

(Quality record form)
The quality record form is a form on which work results in all manufacturing processes such as material acceptance, process 1, process 2, process 3, and final process in the factory 2 are recorded. The quality record form is created in a format predetermined for each product, for example. Here, with reference to FIG. 2, a configuration example of the quality record form (quality record form 30) will be described.

  As shown in FIG. 2, the quality record form 30 includes, for example, a form number barcode 300, a version number barcode 302, and a record field 304a for the process 1 and a record field 304 for each process such as a record field 304b for the process 2. 304 is included. Here, the form number barcode 300 is a barcode in which a form identification ID for uniquely identifying the issued quality record form 30 is coded. The form identification ID is an example of form identification information in the present invention. The version number barcode 302 is a barcode in which the version number of the quality recording form 30 with the corresponding form identification ID is coded. Although details will be described later, the version number is a number indicating the number of times the quality record form 30 of the corresponding form identification ID has been revised (replaced). The recording column 304 for each process is a recording column for the operator to record work results such as measured values of product quality in each process. Note that the image recognition server 10 determines in advance which recording column 304 corresponds to which step, for example, the recording column 304a is the recording column of step 1 and the recording column 304b is the recording column of step 2. It shall be remembered. As shown in FIG. 2, the recording column 304 for each process includes a plurality of character recording columns for recording one character such as “2” and “5”, for example. According to this configuration, when OCR (Optical Character Recognition) is performed on the recording column 304 of each process, it is easy to specify each recorded character, so that the accuracy of recognition of each character is improved. Is possible.

  Further, as shown in the record column 304a of the process 1, the record column 304 of each process further includes, for example, a column for entering names of workers and responsible persons in the corresponding process. Further, the recording column 304 of each process may further include a comment column and a remarks column for the operator to enter supplementary information.

[1-1-2. MFP 20]
The multi-function device 20 is an example of a scanner in the present invention. The multifunction machine 20 has a function of scanning a paper medium and a function of printing electronic data on the paper medium. The multifunction machine 20 is installed in the factory 2, for example, and is used for scanning a form such as a quality record form and registering the scanned data in the image recognition server 10. In FIG. 1, an example in which only one multifunction machine 20 is installed in the factory 2 is illustrated. However, the present invention is not limited to such an example, and a plurality of multifunction machines 20 may be installed in the factory 2.

  Here, with reference to FIG. 3, the configuration of the multi-function device 20 will be described in more detail. FIG. 3 is a functional block diagram showing the configuration of the multifunction machine 20. As illustrated in FIG. 3, the multi-function device 20 includes a control unit 200, a communication unit 220, a scanning unit 222, and a printing unit 224.

(1-1-2-1. Control unit 200)
The control unit 200 generally controls the operation of the multifunction device 20 using hardware such as a CPU (Central Processing Unit) and a RAM (Random Access Memory) built in the multifunction device 20.

(1-1-2-2. Communication unit 220)
The communication unit 220 transmits and receives information to and from other devices via the communication network 22 or the like, for example. For example, the communication unit 220 transmits, to the image recognition server 10, data of a quality recording form scanned by a scanning unit 222 described later under the control of the control unit 200.

(1-1-2-3. Scanning Unit 222)
The scanning unit 222 optically reads various forms and records them as digital still images. For example, the scan unit 222 records the form as a digital image by shining light on the arranged form and converting the reflected light into an electrical signal by the image sensor.

(1-1-2-4. Printing unit 224)
The printing unit 224 prints information such as characters and images on a paper medium using, for example, ink or toner, under the control of the control unit 200.

[1-1-3. Communication network 22]
The communication network 22 is a wired or wireless transmission path for information transmitted from a device connected to the communication network 22. For example, the communication network 22 may include a public line network such as a telephone line network, the Internet, and a satellite communication network, various LANs including the Ethernet (registered trademark), a wide area network (WAN), and the like. . The communication network 22 may include a dedicated line network such as an IP-VPN (Internet Protocol-Virtual Private Network).

  Note that the information processing system according to the present embodiment is not limited to the configuration described above. For example, instead of the multifunction device 20, a scanner and a printer may be installed in the factory 2 (as independent devices).

<1-2. Organizing issues>
By the way, since the quality record form is a form for recording the quality of the product in each process, it is not allowed to falsify information recorded in the quality record form. However, it is difficult to completely prevent the quality record form from being falsified due to the fact that the quality record form is recorded by hand. For example, the recorded information in the previous process may be falsified by the operator in the subsequent process.

  FIG. 4 is an explanatory view showing an example in which the record information of the process 1 is falsified in the period between the process 1 and the process 2 in the quality record form 30 shown in FIG. Specifically, in the character recording column 3040 shown in FIG. 4, “1” was recorded when step 1 was completed as shown in FIG. 2, but when step 2 was completed as shown in FIG. It has been rewritten as “2”. This tampering is performed, for example, by the operator painting “1” with a correction liquid and overwriting “2”.

  Conventionally, various measures have been taken to detect and prevent such alteration of the quality record form. For example, a method is adopted in which each time a process is completed, a worker records a quality record form in which the results of each process are added with a multifunction machine and records the completion report at that time in the production management system. . More specifically, in this method, the factory worker scans the quality record form when step 1 is completed and records the result of step 1 in the quality record form, and starts step 2 when the scan is completed. After that, the process 2 is completed, and when the result of the process 2 is recorded in the quality record form, the operation of scanning the quality record form is repeated. Then, the production management system restricts the work of the next process from being performed when an incompleteness is detected in the record information in a process in the middle of the series of manufacturing processes. In addition, at this time, the production management system reexamines the record information of the previous process recorded in the quality record form, and if the recorded content has changed from the scanned state when the previous process is completed, Judge that tampering has occurred.

  However, the known technique cannot automatically restore the falsified recording information to the content before falsification.

  In addition, a method of continuing to use the same quality record form, for example, by adding a strikethrough to the altered part, is also conceivable. However, in this method, an operator must rerecord the record information before falsification in the quality record form, which may cause a recording error. For example, when a plurality of strikethroughs are described, it is difficult for the worker to recognize which correct record information is, and the function as a quality record form may be impaired.

  As another method, when it is detected that falsification has been detected, the record information of the previous process that has already been registered in the production management system is printed on a blank sheet, and the worker can then print the printed form. A method of rewriting the record information of the current process is also conceivable. However, in this method, since the operator records the recording information of the current process, a recording error may still occur. Also, work efficiency is poor.

  In view of the above circumstances, the image recognition server 10 according to the present embodiment has been created. When the image recognition server 10 according to the present embodiment determines that the record information of the previous process in the quality record form is falsified, the record information of the previous process is restored to the content before the falsification, and the current process It is possible to automatically generate a form including recorded information. Hereinafter, embodiments of the present invention will be sequentially described in detail.

<< 2. Detailed Description of Embodiment >>
<2-1. Configuration>
First, the configuration of the image recognition server 10 according to the present embodiment will be described in detail. FIG. 5 is a functional block diagram showing the configuration of the image recognition server 10. As illustrated in FIG. 5, the image recognition server 10 includes a control unit 100, a communication unit 120, and a storage unit 122.

[2-1-1. Control unit 100]
The control unit 100 generally controls the operation of the image recognition server 10 using hardware such as a CPU 150 and a RAM 154 described later built in the image recognition server 10. Further, as shown in FIG. 5, the control unit 100 includes a form identification information specifying unit 102, a process data specifying unit 104, a result data acquiring unit 106, a comparing unit 108, an image composition unit 110, a transmission control unit 112, and A process data recording unit 114 is included.

[2-1-2. Form identification information specifying unit 102]
The form identification information specifying unit 102 specifies the form identification ID from the scan data of the quality record form received from the multifunction machine 20. For example, if the form identification ID is recorded as a barcode (hereinafter referred to as a form identification ID barcode) in the quality record form, the form identification information specifying unit 102 may include the form included in the received scan data. The form identification ID is specified by analyzing the image of the identification ID barcode. Alternatively, when the form identification ID is recorded as a character string in the quality record form, the form identification information specifying unit 102 performs character recognition on the print location of the form identification ID included in the received scan data. Thus, the form identification ID is specified.

[2-1-3. Process data identification unit 104]
The process data identification unit 104 is an example of a recording information identification unit in the present invention. The process data specifying unit 104 specifies data related to the current process and data related to the previous process from the scan data of the received quality record form. The current process is an example of the second process in the present invention, and the previous process is an example of the first process and the third process in the present invention. The previous process is one of the processes preceding the current process.

(2-1-3-1. Identification of data relating to current process)
For example, the process data specifying unit 104 specifies an image of the recording area of the current process from the received scan data. More specifically, the process data identification unit 104 firstly identifies the process of the last process among the process numbers recorded in the record data DB 124 in association with the form identification ID identified by the form identification information identification unit 102. The number is acquired from the performance data DB 124. Then, the process data specifying unit 104 specifies the process number of the process immediately after the acquired process number as the process number of the current process. Then, the process data specifying unit 104 extracts an image of the recording area corresponding to the specified process number of the current process in the received scan data.

  The process data specifying unit 104 can perform character recognition on the recording area of the current process in the received scan data, and can also specify the recognition result as recording information of the current process.

(2-1-3-2. Identification of data relating to previous process)
Further, the process data specifying unit 104 specifies an image of the recording area of the immediately preceding process from the received scan data. More specifically, the process data specifying unit 104 specifies the process number of the last process acquired from the performance data DB 124 as the process number of the immediately preceding process. Then, the process data specifying unit 104 extracts an image of the recording area corresponding to the process number of the immediately preceding process specified in the received scan data.

  The process data specifying unit 104 can also perform character recognition on the recording area of the immediately preceding process in the received scan data, and specify the recognition result as the recording information of the immediately preceding process.

-Performance data DB124
The performance data DB 124 is an example of a first database in the present invention. The performance data DB 124 is a database that stores images of recording areas of each process included in the scan data received from the multifunction device 20. Here, with reference to FIG. 6, the structural example of performance data DB124 is demonstrated. As shown in FIG. 6, in the record data DB 124, for example, a form identification ID 1240, a process number 1242, and an image 1244 are associated with each other. Here, the form identification ID of the quality recording form is recorded in the form identification ID 1240. Further, in the process number 1242, a process number corresponding to the image of each stored recording area is recorded with respect to the quality recording form of the corresponding form identification ID. Further, the image 1244 stores an image of the recording area of the process having the corresponding process number in the quality recording form having the corresponding form identification ID.

  For example, the example shown in FIG. 6 indicates that the process number of the process in which the image of the recording area has been stored (that is, the previous process) is “1” for the quality recording form whose form identification ID is “0001”. ing.

[2-1-4. Actual data acquisition unit 106]
The performance data acquisition unit 106 acquires an image of the recording area of the previous process in the quality recording form of the form identification ID specified by the form identification information specification unit 102 from the performance data DB 124. For example, the record data acquisition unit 106 corresponds to the process number of the immediately preceding process among the images in the recording area stored in the record data DB 124 in association with the form identification ID specified by the form identification information specifying unit 102. Get an image.

  As a modification, when a character recognition result DB (not shown), which is a database in which the result of character recognition of the image of the recording area of each process is stored in association with the form identification ID, is provided. The result data acquisition unit 106 displays the result of character recognition corresponding to the form identification ID specified by the form identification information specifying unit 102 and the process number of the immediately preceding process acquired by the process data specifying unit 104 as the previous process. It can also be acquired from the character recognition result DB as recorded information.

[2-1-5. Comparison unit 108]
(2-1-5-1. Comparative Example 1)
The comparison unit 108 confirms the identity of the record information of the previous process by comparing the data related to the previous process specified by the process data specifying unit 104 and the data related to the previous process acquired by the result data acquisition unit 106. To do. For example, the comparison unit 108 matches the image of the recording area of the previous process specified by the process data specifying unit 104 with the image of the recording area of the previous process acquired by the result data acquisition unit 106, thereby Confirm the identity of the recorded information. Alternatively, the comparison unit 108 matches the character recognition result of the recording area of the previous process specified by the process data specifying unit 104 with the result of character recognition of the recording area of the previous process acquired by the record data acquisition unit 106. By doing so, the identity of the recording information of the previous process is confirmed.

  Alternatively, the comparison unit 108 first determines the result of character recognition for a plurality of character record fields in the record field of the previous process specified by the process data specification unit 104 and the record field of the previous process acquired by the result data acquisition unit 106. Are matched with the results of character recognition in a plurality of character record fields. Then, the comparison unit 108 includes an image of a region other than the character recording column such as the name entry column, the comment column, and the remarks column in the recording column of the previous process specified by the process data specifying unit 104, and the result data acquisition unit 106. The image in the area other than the character recording field in the recording field of the previous process acquired by the above is matched. If the two matching results indicate that they are the same, it is determined that the recording information of the previous process is the same.

  Here, with reference to FIG. 2 and FIG. 4, said function is demonstrated in detail. Here, the image of the recording column 304a of step 1 in the quality record form 30a shown in FIG. 2 is stored in the performance data DB 124, and the scan data of the quality record form 30b shown in FIG. 4 is combined. It is assumed that it is received from the machine 20.

  As described above, the characters recorded in the character record column 3040 shown in FIG. 4 are different between the quality record form 30a and the quality record form 30b. Therefore, in this example, the comparison unit 108 uses the image of the recording column 304a of the process 1 specified by the process data specifying unit 104 and the image of the recording column 304a of the process 1 acquired by the performance data acquisition unit 106. It matches and it determines with the recording information of process 1 not being the same.

(2-1-5-2. Comparative Example 2)
In addition, when there are a plurality of previous processes, the comparison unit 108, for each of the plurality of previous processes, the data related to the process specified by the process data specifying unit 104 and the data acquired by the result data acquiring unit 106 The identity of the recorded information of each process is confirmed by comparing the data regarding the process.

(2-1-5-3. Comparative Example 3)
In addition, when the form identification information specifying unit 102 specifies the form identification ID, the comparison unit 108 associates the version number recorded in the version number DB 126 with the specified form identification ID and the received scan. The identity of the version number is confirmed by comparing the version number indicated by the version number information included in the data. For example, the comparison unit 108 first identifies the version number by performing image analysis or character recognition on the version number information included in the received scan data. Then, the comparison unit 108 extracts the version number recorded in the version number DB 126 in association with the form identification ID specified by the form identification information specifying unit 102. Then, the comparison unit 108 confirms the identity of the version number by comparing the version number specified from the scan data with the version number extracted from the version number DB 126. The version number information is a barcode (hereinafter referred to as a version number barcode) or a number such as “1.0”.

  The comparison unit 108 transmits a result of checking the version number identity to the transmission control unit 112 described later.

-Version number DB126
The version number DB 126 is an example of a second database in the present invention. The version number DB 126 is a database in which the latest version number is stored in association with the form identification ID. Here, a configuration example of the version number DB 126 will be described with reference to FIG. As shown in FIG. 7, in the version number DB 126, for example, a form identification ID 1260 and a version number 1262 are associated with each other. Here, the form identification ID 1260 records the form identification ID of the quality record form. In the version number 1262, the latest version number of the quality recording form of the corresponding form identification ID is recorded. If the version number information is a version number barcode, the version number 1262 may store an image of the version number barcode.

[2-1-6. Image composition unit 110]
(2-1-6-1. Synthesis Example 1)
When the comparison unit 108 confirms that the recording information of the previous process is not the same, the image synthesis unit 110 and the image of the recording area of the previous process acquired by the record data acquisition unit 106 and the process data specifying unit 104 By combining the image of the recording area of the current process specified by the above, an image of the revised form is generated. For example, in the case described above, the image composition unit 110, in the received scan data, the image of the recording area of the previous process identified by the process data identification unit 104 is acquired by the actual data acquisition unit 106. The image replaced with the image in the recording area is generated as a revised form image.

  In the case where there are a plurality of previous processes, the image composition unit 110 includes a process data specifying unit for each of the previous processes determined by the comparison unit 108 that the recorded information is not the same among the plurality of previous processes. An image obtained by replacing the image of the recording area of the process specified by 104 with the image of the recording area of the process acquired by the record data acquisition unit 106 is generated as a revised form image.

  Here, with reference to FIG. 8 and FIG. 9, the above function will be described in more detail. The scan data 40 shown in FIG. 8 is data obtained by scanning the quality record form 30b shown in FIG. Further, the result data 42 of step 1 shown in FIG. 8 is an image of the recording column 304a of step 1 stored in the result data DB 124 in association with the form identification ID of the quality record form 30b.

  As described above, when the scan data 40 shown in FIG. 8 is received, the comparison unit 108 determines that the recording information in step 1 is not the same. Therefore, the image composition unit 110 generates the revised form image 44 as shown in FIG. 9 by replacing the record field 404a of step 1 included in the scan data 40 with the result data 42 of step 1. .

  According to this synthesis example, when the record information of the previous process in the quality record form is falsified, the record information of the process is restored to the record information before falsification, and the form including the record information of the current process is It can be generated automatically.

(2-1-6-2. Synthesis Example 2)
In addition, when the comparison unit 108 confirms that the recording information of the previous process is not the same, the image composition unit 110 adds a predetermined value to the value indicated by the version number information included in the received scan data. The new version number information including the revised value is further combined to generate a revised form image. For example, in the above case, the version number information is a version number barcode, and the image composition unit 110 first converts the version number analyzed from the version number barcode included in the received scan data. A predetermined value is added, and a barcode for the version number in which the calculated value is encoded is generated. Then, the image composition unit 110 further replaces the version number barcode included in the received scan data with the generated version number barcode, thereby generating an image of the revised form.

  Alternatively, in the case where the version number information is a number and in the above case, the image composition unit 110 first recognizes the version number information included in the received scan data, and then sets a predetermined result in the recognition result. The new version number information is calculated by adding the values of. Then, the image composition unit 110 further replaces the version number information included in the received scan data with the calculated version number information, thereby generating a revised form image.

(2-1-6-3. Recording of version number information)
Furthermore, the image composition unit 110 records the value indicated by the version information after revision in the version number DB 126 in association with the form identification ID specified by the form identification information specifying unit 102.

[2-1-7. Transmission control unit 112]
When the comparison unit 108 confirms that the version number information is not the same, the transmission control unit 112 causes the multifunction device 20 to transmit a notification of mismatch of the version number information to the communication unit 120. According to this control example, according to the notification received from the image recognition server 10, the multifunction device 20 is, for example, that the scanned quality record form is an old version quality record form (that is, a falsified quality record form). Can be displayed, or a buzzer can be output. Then, the worker can be warned to stop using or discard the altered quality record form.

  When the image composition unit 110 generates a revised form image, the transmission control unit 112 causes the communication unit 120 to transmit the generated image to the multifunction device 20.

For example, one or more of the performance data DB 124 and the version number DB 126 may be stored in another device (not shown) that can communicate with the image recognition server 10 instead of being stored in the storage unit 122. It is. Further, the performance data DB 124 and the version number DB 126 may be configured as an integrated database instead of being configured as separate databases.

<2-2. Operation>
The configuration according to this embodiment has been described above. Subsequently, an operation according to the present embodiment will be described. In the following, an example of operation in a scene where the worker of the factory 2 completes the work of one process (current process) related to a product and records the results of the current process in a quality record form will be described.

[2-2-1. Overall behavior]
FIG. 10 is a sequence diagram showing an operation according to the present embodiment. As shown in FIG. 10, first, the worker causes the multi-function device 20 to scan a quality record form in which the results of the current process are recorded (S101). Then, the communication unit 220 of the multifunction device 20 transmits the data scanned in S101 to the image recognition server 10 according to the control of the control unit 200 (S103).

  Thereafter, the form identification information specifying unit 102 of the image recognition server 10 specifies the form identification ID by performing image analysis on the form identification ID barcode included in the scan data received in S103. Then, the comparison unit 108 identifies the version number by performing image analysis on the version number barcode included in the scan data (S105).

  Subsequently, the comparison unit 108 extracts the version number recorded in the version number DB 126 in association with the form identification ID specified in S105 (S107).

  Then, the comparison unit 108 checks whether or not the version number identified in S105 is the same as the version number extracted in S107 (S109). When it is confirmed that the version numbers are not the same (S109: No), the transmission control unit 112 causes the multifunction device 20 to transmit a notification of mismatch of the version number information to the communication unit 120 (S111). Then, for example, the multifunction device 20 displays the content of the notification received in S111 or outputs a buzzer. Thereafter, the multifunction machine 20 ends the operation.

  On the other hand, when it is confirmed that the version numbers are the same (S109: Yes), the image recognition server 10 performs a “replacement necessity determination process” described later (S113).

  Thereafter, when the recording information of the previous process is not replaced in S113 (S115: No), the image recognition server 10 ends the process.

  On the other hand, when the recording information of the previous process has been replaced (S115: Yes), the transmission control unit 112 sends the image of the revised quality recording form generated in S113 to the multifunction device 20 to the communication unit 120. Transmit (S117).

  After that, the printing unit 224 of the multifunction machine 20 prints the image received in S117 on a paper medium and outputs it (S119).

[2-2-2. Replacement necessity determination process]
Here, the operation of the “replacement necessity determination process” in S113 will be described in detail with reference to FIG. 11 and FIG. As shown in FIG. 11, first, the control unit 100 of the image recognition server 10 sets “0” as the number of replacements corresponding to the scan data received in S103, and holds the number of replacements after the setting. (S201).

  Subsequently, the process data specifying unit 104 acquires the process number of the last process among the process numbers recorded in the record data DB 124 in association with the form identification ID specified in S105 from the record data DB 124, and The acquired process number is held as the process number of the previous process. Then, the process data specifying unit 104 specifies the process number of the process immediately after the acquired process number as the process number of the current process (S203).

  Subsequently, the process data specifying unit 104 determines whether or not the process number of the previous process is “0”, that is, whether or not there is a previous process (S205). When the process number of the previous process is “0” (S205: Yes), the image recognition server 10 performs the operation of S251 described later.

  On the other hand, when the process number of the previous process is not “0” (S205: No), the process data specifying unit 104 first records the recording area corresponding to the process number of the previous process in the scan data received in S103. Is identified (S207).

  Subsequently, the record data acquisition unit 106 acquires an image of the recording area stored in the record data DB 124 in association with the form identification ID specified in S105 and the process number of the previous process from the record data DB 124 (S209). ).

  Subsequently, the comparing unit 108 matches the image of the previous process recording area identified in S207 with the image of the previous process recording area acquired in S209, thereby matching the identity of the previous process recording information. Confirm (S211). When it is confirmed that the recording information of the previous process is the same (S213: Yes), the control unit 100 performs an operation of S219 described later.

  On the other hand, when it is confirmed that the recording information of the previous process is not the same (S213: No), the image composition unit 110 records the recording area of the previous process specified in S207 out of the scan data received in S103. Is replaced with the image of the recording area of the previous process acquired in S209, thereby generating an image of the quality recording form (S215).

  Subsequently, the image composition unit 110 adds “1” to the number of replacements held (S217).

  Subsequently, the control unit 100 reduces the retained process number of the previous process by “1” (S219). Then, the control unit 100 repeats the operation of S205 again.

  Here, with reference to FIG. 12, an operation when it is determined in S205 that the process number of the previous process is “0” (S205: Yes) will be described. As shown in FIG. 12, first, the image composition unit 110 determines whether or not the number of replacements held is equal to “0” (S251). When the number of replacements is equal to “0” (S251: Yes), the image recognition server 10 performs the operation of S257 described later. If the number of replacements is equal to “0”, it means that no falsification has been detected in the corresponding quality record form.

  On the other hand, when the number of replacements is not equal to “0” (S251: No), the image composition unit 110 displays a version number barcode in which a value obtained by adding 1 to the version number specified in S105 is encoded. Generate (S253).

  Subsequently, the image composition unit 110 replaces the version number barcode included in the (final) image generated in S215 with the version number barcode generated in S253, so that the revised quality record form Is generated (S255). Note that the image of the quality record form after the revision is transmitted to the multi-function device 20 in S117.

  Thereafter, the process data specifying unit 104 extracts an image of the recording area corresponding to the process number of the current process specified in S203 from the scan data received in S103 (S257).

  Then, the process data recording unit 114 associates the image of the recording area of the current process extracted in S257 with the form identification ID specified in S105 and the process number of the current process specified in S203 in the performance data DB 124. Store (S259).

<2-3. Effect>
As described above, for example, with reference to FIGS. 5 and 10 to 12, the image recognition server 10 according to the present embodiment specifies the form identification ID from the scan data of the quality record form received from the multifunction device 20. The image of the recording area of the previous process stored in the result data DB 124 in association with the specified form identification ID is compared with the image of the recording area of the previous process included in the scan data, and When it is confirmed that the recording information of the process is not the same, the image of the recording area of the previous process stored in the record data DB 124 and the image of the recording area of the current process included in the scan data are combined. As a result, an image of the revised quality record form is generated.

  For this reason, when it is determined that the record information of the previous process included in the received scan data is falsified, the image recognition server 10 restores the record information of the process to the content before the falsification, and It becomes possible to automatically generate a quality record form including record information of the current process.

  Therefore, in order to restore the falsified record information to the contents before falsification, for example, an operator of the factory 2 adds a strikethrough to the falsified quality record form and transcribes the record information before falsification. Or, there is no need for human work such as transferring the recording information of the current process to the paper medium on which the image of the recording area of the previous process stored in the result data DB 124 is printed. For this reason, it is possible to prevent occurrence of a recording error in the recording information. Further, extra description such as a strikethrough is not added to the quality record form, and the visibility of the quality record form is not impaired. Moreover, the work load of the worker can be reduced, and the work efficiency in the factory 2 can be improved.
