The similar character management data 83 is registered as the reading data representing how to read each character in association with character data and hiragana data for each character that is likely to be misread. Here, for the sake of convenience, the reading is “Hiragana”. However, in the case of a symbol, since there is actually no one-to-one hiragana, the symbol is registered as it is.

<Operation of information processing system>
Hereinafter, the operation of the information processing system (here, the exchange system 1) will be described with reference to FIG. FIG. 4 is a flowchart showing the operation of the information processing system according to this embodiment.

  The operation of each device is defined by a control program stored in advance in a readable manner in the storage unit of each device, and is executed by the control unit of each device. In addition, each data is temporarily stored in a storage unit so as to be readable, and then output to a required component that performs subsequent processing. Hereinafter, since these points are conventional means in information processing, detailed description thereof will be omitted.

  FIG. 4 shows, on the display device 27, the recognized characters obtained as a result of character recognition of the entered characters entered in the form from the form reading process for optically reading the form image (S 105) and how to read them in association with each other. The operation up to the reading display process (S150) to be performed is shown.

  In FIG. 4, processing indicated by a dotted frame means processing performed by a device other than the operation terminal 26, and processing indicated by a solid line frame means processing performed by the operation terminal 26. The main features of the operation of the exchange system 1 are the “Hiragana conversion (reading specification)” process (S140) and the “reading display” process (S150) performed by the operation terminal 26.

For example, the exchange system 1 operates as follows.
For example, a customer visits a sales office 10 of a financial institution to deposit cash, withdraw, transfer, borrow, and enter various items in a form 101 (see FIG. 5) according to the purpose. At this time, the customer enters characters such as kanji, katakana, hiragana, numbers, and symbols in a predetermined entry field of the form 101 (see FIG. 5). FIG. 5 is a diagram illustrating an example of a form used in the present embodiment.

  When the customer completes the entry, the customer submits the form 101 to the sales office 10. When the operator working at the sales office 10 receives the form 101 from the customer, the operator instructs the optical reading device (here, the scanner device 12 or the FAX 13) to read the image of the form 101. Thereby, the exchange system 1 starts processing of a series of routines shown in FIG.

  At this time, for example, the branch office terminal 11 of the branch office 10A acquires the image data of the form 101 from the scanner device 12 connected to the branch office terminal 11, and uses the image data of the form 101 as the image processing server 22 of the exchange center 20. (S105).

  When the image processing server 22 of the exchange center 20 receives the image data of the form 101 from the store terminal 11 of the store 10A, the image data of the form 101 is temporarily stored in the DB server 21 (S110).

  Next, the image processing server 22 reads the image data of the form 101 from the DB server 21, sets the input characters (including symbols) included in the image data of the form 101 as character recognition targets, and sets the input characters as characters. Recognize (S115). As a result, the image processing server 22 acquires recognized character data corresponding to the entered characters. Thereafter, the image processing server 22 stores the recognized character data obtained in the process of S115 in the DB server 21 (S120).

  The exchange system 1 causes the FAX 13 of the branch office 10B to optically read the image of the form 101 and transmit the image data of the form 101 acquired thereby to the FAX processing server 23 of the exchange center 20 in S105. It may be. In this case, the FAX processing server 23 of the exchange center 20 stores the image data of the form 101 received from the FAX 13 of the sales office 10B in the DB server 21 in S110, and the image of the form 101 from the DB server 21 in S115. The configuration is such that the data is read, the entered characters included in the image data of the form 101 are recognized, and the recognized character data obtained in S115 is stored in the DB server 21 in S120.

  After S120, in the exchange center 20, the operation terminal 26 performs the following processing in response to the operation of the operator working at the exchange center 20.

  First, in the operation terminal 26, the screen display control unit 61 (see FIG. 2) displays, for example, the transaction screen 201 shown in FIG. 6 on the display device 27 as a display screen (S125).

  FIG. 6 is a diagram illustrating an example of a display screen according to the present embodiment. As shown in FIG. 6, the transaction screen 201 displays a written character image entered in the form 101, a recognized character image obtained by a character recognition device (here, the image processing server 22 or the FAX processing server 23), and the like. The form is reflected in form data prepared in advance corresponding to the form 101.

  For example, in the example shown in FIG. 6, the transaction screen 201 is configured to include a display field 301 that displays data related to the name of the recipient and a display field 302 that displays data related to the name of the client.

  The display field 301 displays a “recipient kanji image data” display field in which an entry character image representing the name of the recipient in kanji written on the form 101 is displayed, and a recognition character image corresponding to the entry character. The “Kanji recognized character data” display field is arranged close to (adjacent) in the vertical direction of the screen. The display column 301 is a “recipient kana image data” display column (hereinafter referred to as an “image data display column 301a”) in which an entry character image representing the name of the recipient in katakana written in the form 101 is displayed. ), A “Kana recognized character data” display field (hereinafter referred to as “recognized character display field 301 b”) in which a recognized character image corresponding to the entered character is displayed, and a hiragana character image obtained by converting the recognized character into a hiragana character ( A “Hiragana data” display field (hereinafter referred to as “reading display field 301 c”) on which “reading data” is displayed is arranged close to (adjacent) in the vertical direction of the screen.

  On the other hand, the display column 302 displays a “client character kanji image data” display column in which a written character image representing the name of the client in Kanji written on the form 101 is displayed, and a recognized character image corresponding to the written character. The “Kanji recognized character data” display field is arranged close to (adjacent) in the vertical direction of the screen. The display field 302 is a “client image data field” display field (hereinafter referred to as an “image data display field 302a”) in which a written character image representing the name of the client in katakana written in the form 101 is displayed. ), A “Kana recognized character data” display field (hereinafter referred to as “recognized character display field 302b”) in which a recognized character image corresponding to the entered character is displayed, and a hiragana character image obtained by converting the recognized character into a hiragana character ( A “Hiragana data” display field (hereinafter referred to as “reading display field 302c”) in which “reading data” is displayed is arranged close to (adjacent) in the vertical direction of the screen. Here, although the operation terminal 26 is configured to display kanji-recognized character data, it does not perform kanji recognition according to the necessity for subsequent processing (thus, the kanji-recognized character data is not displayed). (It may be possible not to provide a display column).

  After S125, in the operation terminal 26, the data acquisition unit 62 acquires the recognized character data from the DB server 21 (or the image processing server 22 or the FAX processing server 23 which is a character recognition device) (S130). The presence / absence determination unit 63 refers to the similar character management data 83 (FIG. 3) and determines the presence / absence of a similar character having a similar shape to the recognized character (S135).

  Next, in the operation terminal 26, the hiragana conversion unit 64 converts the recognized character into the hiragana character for the recognized character determined to have a similar character by the similar character presence / absence determining unit 63 in S135, and the recognized character Is identified (S140). As a result, the operation terminal 26 acquires reading data representing how to read the recognized character. Details of the process of S140 will be described later.

  Next, in the operation terminal 26, the data acquisition unit 62 acquires the image data of the form 101 from the DB server 21 (S145), and the character display control unit 65 further acquires the acquired form 101 as shown in FIG. The character display fields 301 and 302 of the transaction screen 201 are combined (corresponding) to the written character (including symbols) image, the recognized character image, and the hiragana character image (reading data) included in the image data. (See FIG. 6) (S150). Thereby, the exchange system 1 ends the processing of a series of routines shown in FIG. Details of the processing of S150 will be described later.

  When the series of routines is completed, the operator refers to the transaction screen 201 displayed in the process of S150 to check whether there is a misread for each recognized character. Operate to correct the recognition character data of misread characters. Thereafter, the operator causes the operation terminal 26 to communicate with the host computer 30 and instructs the host computer 30 to execute a transaction process requested by the customer.

<Details of S150 Process ("Reading Display"Process)>
The details of the process of S150 ("reading display" process) shown in FIG. 4 will be described below. In the processing of S150 (“reading display” processing), the operation terminal 26 performs the following processing on the transaction screen 201 (see FIG. 6).

  The operation terminal 26 images, for example, a written character image representing the name of the recipient in kana written in the recipient name entry column of the form 101 (see FIG. 5) by the customer for data related to the name of the recipient in katakana. A recognized character image corresponding to the entry character displayed in the data display field 301a and then recognized by the character recognition device is displayed in the recognized character display field 301b, and each recognized character acquired by the hiragana conversion unit 64 is displayed. The hiragana character image corresponding to (reading data) is displayed in the reading display column 301c.

  In addition, the operation terminal 26, for example, for the data related to the name of the client in katakana notation, displays an input character image representing the name of the client in notation written in the client name entry field of the form 101 by the customer in the image data display field. Next, the recognized character image corresponding to the entered character recognized by the character recognition device is displayed in the recognized character display field 302b, and further corresponds to each recognized character acquired by the hiragana conversion unit 64. A hiragana character image (reading data) is displayed in the reading display column 302c.

<Details of “Hiragana Conversion (How to Read)” Processing (S140)>
Hereinafter, with reference to FIG. 7 and FIG. 8, the details of the processing of S140 (“Hiragana conversion (reading specification)” processing) shown in FIG. 4 will be described. 7 and 8 are diagrams each showing an example of hiragana conversion according to the present embodiment.

  In S140 shown in FIG. 4, the hiragana conversion unit 64 of the operation terminal 26 recognizes the recognized character determined as having a similar character by the similar character presence / absence determining unit 63 in S135, for example, as shown in FIG. Is converted into a hiragana character, and how to recognize the recognized character is specified. As a result, the operation terminal 26 acquires reading data representing how to read the recognized character. Then, the character display control unit 65 of the operation terminal 26 recognizes the acquired hiragana character image (reading data) as a recognized character image and character recognition (conversion of recognized character data), for example, as shown in FIG. Displayed in correspondence with the entered character image.

  FIG. 7 shows characters that are prone to misreading in character recognition (specifically, “n”, “shi”, and “) for the recognized character“ Kanzakishibu ”displayed in the recognized character display field 301 b. "(Character of closing parenthesis)" is converted to "Hiragana character", and the hiragana character image is displayed in the reading display column 302c in association with the recognized character image.

  8A displays the recognized character image of the hiragana conversion example shown in FIG. 7 in the recognized character display field 302b of the transaction screen 201, and further displays the hiragana character image of the hiragana conversion example shown in FIG. An example when displayed in the reading display column 302c is shown. As shown in FIG. 8A, in the hiragana conversion example shown in FIG. 7, it can be easily understood that the character (symbol) “” (close bracket) is a misread character of “K” in Katakana.

  FIG. 8B shows an example in which there is no character that is likely to be misread in character recognition. As shown in FIG. 8B, when there is no character that is likely to be misread in character recognition, the reading display column 302c of the transaction screen 201 is in a blank (blank) state.

  The operator refers to the transaction screen 201 (FIG. 6) and compares the recognized character image, the written character image, and, if there is a hiragana character image (reading data), with the hiragana character image (reading data). Check for misreading of recognized characters. At this time, if there is a recognized character image in which the hiragana character image (reading data) is displayed in association with the hiragana character image (reading data), the operator preferentially compares the recognized character image with the hiragana character image (reading data). It is possible to carefully check whether the recognized character is misread.

<Supplementary Notes on "Hiragana Conversion (How to Read)" Processing (S140)>
(1) Conversion of recognized characters to hiragana characters is executed only for characters registered in the similar character management data 83 (see FIG. 3).
(2) The operation terminal 26 sequentially determines whether the recognized character acquired in the process of S130 is a character registered in the similar character management data 83 one by one from the top.
(3) When determining whether or not the operation terminal 26 is a character registered in the similar character management data 83 with respect to the recognized character acquired in the processing of S <b> 130, the character being determined is registered in the similar character management data 83. If the character is a character that has been determined, the character being determined is converted into a hiragana character registered in the “Hiragana” column of the similar character management data 83.
(4) On the other hand, when determining whether or not the operation terminal 26 is a character registered in the similar character management data 83 with respect to the recognized character acquired in the processing of S130, the character under determination is similar character management data 83. If the character is not registered in, the character under determination is converted to a space.

<Supplementary information on similar character management data>
(1) In the similar character management data 83 (see FIG. 3), characters that are likely to be misread in character recognition (for example, katakana “no” and symbol “)” (close bracket) or katakana “shi” And similar characters having similar shapes (such as “tsu”) and characters to be converted (usually hiragana) are registered. The symbol ")" (close bracket) has the same character ")" because there is no corresponding hiragana, but other characters (for example, "ka", "ka", etc.) You may decide to register.

  (2) The operation terminal 26 is preferably provided with a function of causing the display device 27 to display a maintenance display screen of the similar character management data 83, and based on the operation of the operator, the similar character management data update unit 72. (See FIG. 2), it may be configured such that maintenance such as addition / change / deletion of the contents of the similar character management data 83 can be appropriately performed.

<Supplementary information about hiragana display>
(1) The operation terminal 26 recognizes an image data display field 301a, 302a for displaying an entered character image entered in the form 101, a recognized character display field 301b, 302b for displaying a recognized character image corresponding to the entered character, Reading method display fields 301c and 302c for displaying hiragana character images (reading data) corresponding to characters are displayed on the display device 27 in the vertical direction.

  (2) Preferably, when determining whether or not the operation terminal 26 is a character registered in the similar character management data 83 with respect to the recognized character acquired in the process of S130, the character under determination is similar character management data. If the character is registered in 83, for example, the background color of the reading display columns 301c and 302c may be changed as shown in FIG. As a result, the operation terminal 26 can efficiently notify the operator of the presence or absence of characters that are likely to be misread by directing the operator's attention to the reading display fields 301c and 302c.

<Characteristics of operation terminal>
In such a configuration, the operation terminal 26 has the following characteristics.
(1) The operation terminal 26 displays a transaction screen 201 provided with reading display fields 301c and 302c for displaying hiragana character images (reading data) on the display device 27, so that characters that are likely to be misread in character recognition are displayed. The operator can be easily notified of the presence or absence of Thereby, the operator can intensively check the presence or absence of misreading for the recognized characters in which the hiragana character images (reading data) are displayed in association with each other in the reading display columns 301c and 302c. As a result, it is possible to reduce omissions in checking misread characters if misreads occur.

  (2) The operation terminal 26 changes the background color of the reading display fields 301c and 302c, thereby directing the operator's attention to the reading display fields 301c and 302c, and efficiently confirms the presence or absence of characters that are likely to be misread. Can let you know.

  (3) The operation terminal 26 displays only the reading of the characters registered in the similar character management data 83 in the reading display columns 301c and 302c, so that which character in the reading display columns 301c and 302c is the check target. It is possible to easily inform the operator of whether or not. Thereby, the operation terminal 26 can suppress that an operator performs a useless check with respect to the recognition character with a low possibility of being misread.

  (4) The operation terminal 26 displays a space in the reading display fields 301c and 302c corresponding to the recognized character images not to be checked, so that the recognized character images to be checked displayed in the recognized character display fields 301b and 302b. And the position of the hiragana character image (reading data) displayed in the reading display columns 301c and 302c can be matched. Thereby, the operation terminal 26 can easily notify the operator of the position of the recognized character to be checked. For this reason, it is desirable that the fonts used for each display have the same character size at a fixed pitch.

  (5) The operation terminal 26 may appropriately perform maintenance such as addition / change / deletion of the content of the similar character management data 83 by the similar character management data update unit 72 (see FIG. 2) based on the operation of the operator. it can. As a result, the similar character management data 83 can be optimized.

  (6) The operation terminal 26 can transmit the maintained similar character management data 83 to the DB server 21 and store it in the storage unit of the DB server 21. Thereby, the operation terminal 26 can share and manage the similar character management data 83 stored in the DB server 21 among the plurality of operation terminals 26, and as a result, cooperates with other operation terminals 26. The similar character management data 83 can be optimized.

  As described above, according to the information processing apparatus (operation terminal 26) according to the present embodiment, for example, characters that are likely to be misread due to character recognition such as katakana and symbols can be presented to the operator in an easy-to-understand manner. Thereby, the operator can intensively check the presence or absence of misreading for the recognized characters that are displayed in association with the reading. As a result, it is possible to reduce omissions in checking misread characters if misreads occur.

  The present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the gist of the present invention.

  For example, in the above-described embodiment, in the information processing system 1, the external device (the image processing server 22 or the FAX processing server 23) of the information processing device 26 performs character recognition based on the image data of the form, and the information processing device 26 Recognized character data is received from an external device, and a recognized character image is displayed on the display device 27. However, the information processing device 26 may be configured such that the information processing device 26 itself performs character recognition and displays a recognized character image of the recognized character data obtained thereby on the display device 27. Such a configuration can be realized by updating the control program 81 (see FIG. 2) installed in the information processing apparatus 26.

  In addition, for example, the information processing system 1 uses characters entered by a terminal device (not shown) having a handwriting input function such as a tablet in addition to characters entered on a medium as a character recognition target. 26 may display the recognized character image of the entered character input at the terminal device together with the hiragana character image (reading data) indicating how to read the character on the display device 27.
