Data, for example, is transferred to the terminal device 29a. (2) The terminal device 29a displays the transferred image data and transmission data on its display screen. (2) After confirming the displayed image data and transmission data, the operator instructs the host device 32 to transmit the transmission data. This transmission data is transmitted from the character recognition device 27 to the host device 32 via the dedicated communication line 31. Note that the transmission data sent to the host device 32 is composed of kana characters and character codes of numerical information.

(2) The host device 32 executes a predetermined exchange process based on the received data and ends the transaction.

The exchange process was carried out using the procedure described above.

(Problem to be Solved by the Invention) Now, here is a fifth explanation of the operation in which the operator uses the terminal device 29a to confirm the image data and the transmission data.
This will be explained with reference to the figures.

FIG. 5 shows a display example of the display screen of the terminal device 29a.

The figure shows the display on the display screen 33 of the terminal device 29a. On the display screen 33 shown in the figure, a bank name item 34, a branch name item 35, an amount item 36, a client name item 37, and a client code 38 are displayed.

The bank name item 34 is provided with an image data display field 34a and a transmission data display field 34b. Similarly, branch name field 35, amount display field 36, client name field 37,
The client code field 38 includes an image data display field 35.
a, 36a, 37a, 38a and transmission data display field 3
5b. 36b, 37b, and 38b are provided.

In the image data display column 34a of the bank name item 34, “
Image data showing the kanji characters ``東西'' is displayed. Also, in the transmission data display field 34b, transmission data of kana characters such as ``tozai'' is displayed. Display field 34a
This is the result of character recognition of the image data displayed on the screen. Here, it is assumed that the character recognition device 27 is unable to recognize the kanji character ``゛''東西゜゜ displayed in the image data display field 34a. That is,
If the person filling out the money order form 1 enters incorrect characters in the bank name entry column 2b or writes in a disorderly manner, the character recognition device 27 cannot recognize the characters.

In such a case, "?" is displayed in the transmission data display field 34b of the bank name item 34 to notify the operator that the characters could not be recognized. When the operator recognizes this display, the operator manually inputs the transmission data to be displayed in the transmission data display field 34b.

Specifically, the talented person operates the terminal device 29a to input data for transmission. First, the operator moves a cursor or the like (not shown) to the transmission data display field 34b.

Next, expected kana characters are input from the image data display field 34a. In this case, the image data display field 34a determines that content indicating a kanji character such as "tozai" is displayed, and inputs a kana character such as ``tozai''.The character recognition device 27 recognizes this kana character ( Upon receiving the input of "TOZAI"), it is handled as data for transmission, and "TOZAI" is displayed in the transmission data display field 34b.

With the above operations, the correction operations regarding the bank name item 34 are completed.

As explained above, in the past, when performing correction work, the operator had to input all the kana characters (full name) indicating the bank name or branch name. For this reason,
Input operations were time-consuming and hindered speedy processing. Furthermore, there is a problem in that when the number of characters to be input increases, input errors are more likely to occur.

The present invention has been made with attention to the above points, and when performing correction work, there is no need to input all the bank name, branch name, etc., and it is possible to execute the process quickly and prevent the occurrence of input errors. The purpose of this invention is to provide a character recognition processing device that can perform the following functions.

(Means for Solving the Problem) The character recognition device of the present invention includes a recognition means for recognizing the kanji characters based on image data obtained by reading the kanji characters, and converting the recognized kanji characters into kana characters. a kana-kanji conversion dictionary which is referred to when the kana conversion means performs the conversion and which associates the kanji characters with the kana characters; and when the recognition means cannot recognize the kanji characters; Using the supplementary information entered separately,
The kana characters are obtained by referring to the kana-kanji conversion dictionary or the auxiliary dictionary in which the auxiliary information and the kana characters are associated with each other.

(Operation) The above device is provided with a kana-kanji conversion dictionary that associates kanji characters with kana characters, and an auxiliary dictionary that associates auxiliary information with kana characters. If the recognition means cannot recognize kanji characters, auxiliary information is input separately. This auxiliary information is used to refer to the kana-kanji conversion dictionary or auxiliary dictionary. This auxiliary information is information used to identify kana characters that correspond to kanji characters. By referring to the kana-kanji conversion dictionary or the auxiliary dictionary, the kana characters corresponding to the auxiliary information can be obtained.

(Embodiment) FIG. 1 is a block diagram showing an embodiment of a character recognition device of the present invention.

In the figure, a character recognition device 50 includes a processor 51, a storage device 52 made up of a hard disk device, etc., an input section 53 made up of a keyboard etc., a display section 54 made up of a display etc., and an input/output interface ( For example, the communication control unit 55 includes a GPIB standard interface), a modem, and the like. Note that image data from an OCR or the like is input to the input side of the communication control unit 55 (received data). Also, from the output side, output data consisting of character codes or data in which image data and character codes are mixed is output (
sending data).

The processor 5l includes a recognition means 60 and a kana conversion means 6.
1, and a correction processing means 62 is provided. The correction processing means 62 is provided with an auxiliary information determination means 65, a search execution means 66, and a correction data determination means 67. The storage device 52 is provided with a kana-kanji conversion dictionary 70, an auxiliary dictionary 71, and a character pattern storage means 72.

The kana-kanji conversion dictionary 70 in the storage device 52 consists of a conversion table in which a kanji character table 70a and a kana character table 70b are associated one-to-one. The kanji character table 70a is composed of character codes in which each item indicates a kanji character (name expressed in kanji) of a name such as a bank name or branch name. Similarly, in the kana character table 70b, each item is a kana character (such as bank name or branch name).
It consists of a character code indicating the name (name in kana expression). The auxiliary dictionary 71 consists of a conversion table in which a numerical code table 71a and a kana character table 7lb are associated one-to-one. The numerical code table 71a is composed of numerical codes in which each item indicates a numerical code (bank number and branch number) for identifying a bank or its branch. The kana character table 7lb is the kana character table 7 of the kana-kanji conversion dictionary 70.
Like 0b, it is composed of character codes indicating kana characters.

The recognition means 60 of the processor 51 recognizes the image data from the received data received by the communication control section 55 and generates the corresponding kanji character (array of a plurality of character codes) based on the data stored in the character pattern storage means 72. This is what you get. The kana conversion means 6l refers to the kana-kanji conversion dictionary 70 to obtain kana characters corresponding to the kanji characters recognized by the recognition means 60. That is, the kana conversion means 6l refers to the kanji character table 70a of the kana-kanji conversion dictionary 70 using the character code of the kanji character. By referring to the kanji character table 70a, the contents of the corresponding kana character table 70b (the character code of the kana character) can be obtained.

The correction processing means 62 performs a process of creating data for transmission based on the image data for which the recognition means 60 could not perform character recognition. That is, the auxiliary information determining means 65 of the correction processing means 62 uses the input section 53
It is used to determine whether the auxiliary information input from the input is a kana or a numerical code. The search execution means 66 refers to the kana-kanji conversion dictionary 70 or the auxiliary dictionary 71, based on the determination result of the auxiliary information determination means, and executes a search for kana characters corresponding to the auxiliary information. The correction data determining means 67 selects and determines a desired one from among the kana characters obtained by the search performed by the search executing means 66.

Now, the operation of the character recognition device 50 having the above configuration will be explained with reference to FIG.

FIG. 6 shows a display example of the display screen 54a of the display means 54.

The figure shows the display on the display screen 54a of the display means 54.

The display screen 54a shown in the figure displays a bank name item 34, a branch name item 35, an amount item 36, a client name item 37, a client code item 38, and a selection candidate item 39. The bank name item 34 is provided with an image data display field 34a and a transmission data display field 34b. Similarly, branch name field 35, amount display field 36, client name field 37,
The client code field 38 includes an image data display field 35.
a, 36a, 37a, 38a and transmission data display field 3
5b. 36b. 37b and 38b are provided. Further, the selection candidate item 39 is provided with a selection candidate display field 39a.

In the image data display column 34a of the bank name item 34, “
Image data showing the kanji characters "Tozai" is displayed. Also, in the transmission data display field 34b, transmission data of kana characters such as "Tozai" is displayed. This transmission data is the image data Display 1'J]
This is the result obtained by character recognition of the image data displayed in 3 4a and then kana conversion.

Here, the character recognition device 27 selects the image data display field 3.
Assume that the Kanji character "Tozai" displayed in 4a cannot be recognized. That is, if the person filling out the money order form 1 writes two incorrect characters in the bank name entry column 2b or writes the entries in a random manner, the character recognition device 27 will recognize the following: Unable to perform character recognition.

In such a case, a "?" is displayed in the transmission data display field 34b of the bank name field 34 to notify the operator that the characters could not be recognized. When the operator recognizes this display, the operator manually inputs the transmission data to be displayed in the transmission data display field 34b (execution of correction work). Specifically, the operator operates the input unit 53 to perform correction work. First, the operator moves a cursor (not shown) to the transmission data display field 34b. Next, assumed auxiliary information (kana characters or numerical code) is input from the image data display field 34a. In this case, “
It determines that content indicating kanji characters such as ``東西'' is displayed, and inputs a kana character such as ``tou.''
“Tou” is an abbreviation of “Tozai,” which is a kana pronunciation of “Tozai.” The auxiliary information determining means 65 of the correction processing means 62 determines whether the auxiliary information input from the input section 53 is a kana character or a numerical code. In this case, the determination result by the auxiliary information determining means 65 indicates a kana character. Next, the search execution means 66, based on the auxiliary information and the determination result,
A search of the kana character table 70b of the kana-kanji conversion dictionary 70 is executed. As a result of this search, the kana character table 70b
Among the items, items starting with “tou” are extracted. The correction data determining means 67 displays the kana characters extracted by the search execution means 66 in the selection candidate display column 3 of the display screen 54a.
Display on 9a. Here, it is assumed that two types of kana characters starting with "tou" are extracted: "touzai" and "tounan." The operator selects "Tozai" from among the candidates displayed in the selection candidate display column 39a. Specifically, the numerical value displayed at the beginning of each candidate character is input from the input section 53. In this case “1”
Enter . When the corrected data determining means 67 recognizes that "1" has been input, it displays "Tozai" in the transmission data display column 34b of the bank name field 34, and further displays kana characters indicating this "Tozai". Perform processing to make the data for transmission. Now, when the operator inputs numerical information (for example, the numerical value "1") instead of kana characters from the input unit 53, the determination result of the auxiliary information determining means 65 indicates numerical data. next,
The search execution means 66 executes a search in the numerical code table 71a of the auxiliary dictionary 71 based on the auxiliary information and the determination result. As a result of this search, items with content "l" are extracted from among the items in the numerical code table 71a. moreover,
The search execution means 66 reads out the kana character table 7lb corresponding to the item of content "1" in the numerical code table 71a. As a result, the search execution means 66 obtains kana characters such as "tozai". The corrected data determining means 67 displays the kana characters of "Tozai" obtained as a result of the search by the search execution means 66 in the transmission data display column 34b of the display screen 54a, and
Processing is performed to use kana characters indicating , as data for transmission. Here, a case will be described in which the character recognition device 50 having the above configuration is applied to a money exchange data communication device. FIG. 7 is a block diagram of a money exchange data communication device according to the present invention. In the exchange data communication device 20 shown in the figure, the branch 2
1 consists of a character recognition device 50, an optical character reader (OCR) 22, a keyboard 23, and a network control unit (NCU) 24 connected to the character recognition device 50. ．． District center 2
6 is a character/character recognition device 50 and a network control unit (N
CU) 28 and terminal devices 29a and 29b. The NCU 24 of the branch 21 is connected to the NCU 28 of the district center 26 via the public communication network 30.
The character recognition device 50 of the district center 26 is connected to the dedicated communication line 3l.
It is connected to the host device 32 via. The OCR 22 of the branch 21 optically reads the characters written on the exchange form 1 and outputs image data thereof. The keyboard 23 is for inputting kana characters and numerical values, and the NCU 24 is composed of a modem and the like that converts data in the branch 21 into audible signals for transmission to the public communication network 30. The character recognition device 50 in the district center 26 recognizes characters from the data (image data) of the exchange form 1 received from the branch 21. Like the NCU 24, the NCU 28 is composed of a modem and the like. Terminal equipment 29
a and 29b are used to confirm character data etc. recognized by the character recognition device 50 and to instruct transmission to the host device 32.

Note that the character recognition device 50 installed in the branch office 2l recognizes characters other than kanji. Further, it is assumed that the character recognition device 50 provided at the district center 26 recognizes kanji. By limiting the characters to be recognized in this manner, the branch office 21 can reduce the amount of data sent to the district center 26 using the relatively simple character recognition device 50. In addition, District Center 26
, the input section 53 and display section 54 shown in FIG.
is provided in the terminal devices 29a and 29b. Therefore, here, the correction work is performed using the terminal devices 29a and 29b.

Now, the operation of the money exchange data communication device 2o having the above configuration will be explained with reference to FIG.

FIG. 8 is an operational flowchart of the exchange data communication device 20 according to the present invention. In the figure, first, the exchange form 1 is set in the OCR 22 of the sales office 2l, and the character data is read (step SIO). The character data read by the OCR 22 is input to the character recognition device 50 as image data. In this character recognition device 50, among the image data,
Characters other than kanji (numerical values, kana characters, etc.) are recognized (step Sll). After step Sll, the recognition results are sent to the district center 26 (step S12).
Processing on the branch 2l side ends. Here, the structure of the recognition result (telegram for transmission) transmitted to the district center 26 will be explained using FIG. 9.

Figure 9 is a diagram showing the structure of the transmission message. In the figure, the transmitted message 80 includes a management information section 81, a kanji image data section 82, a character data section 83, and an image data section 84.
It consists of four items. The management information section 8l consists of information such as a management number assigned to identify the exchange form. The kanji image data section 82 consists of image data of items to be filled out in kanji on the exchange form l. The character data section 83 consists of alphanumeric character codes that are recognized at the sales point. Image data section 8
4 consists of image data output by the OCR 22. Now, returning to FIG. 8 again, the district center 26 receives the transmitted message from the sales office 2l (step S20).

The character recognition means 50 of the district center 26 temporarily stores the data received from the branch 2l in a memory element (RAM), etc. (not shown) (step S21).
extracts character data (kanji image data) to be recognized from the received data (step S22). In this case, the kanji image data portion 82 of the transmitted message 80 is extracted. Then, the character recognition means 60 performs character recognition based on the image data of the kanji, and if the character recognition is successfully executed (if the kanji character (character code of the kanji) is obtained based on the image data), the process proceeds to step S24. Move. In step S24, the kana conversion means 61 searches the kana-kanji conversion dictionary 70 (step S24). Then, it is determined whether there is a corresponding item (step S25). Here, if there is no corresponding item, the kana conversion means 61 displays a "?" in the corresponding item on the display screen 54a, for example, in the transmission data display field 34b. Here, the operator will perform correction work. The operator operates the input unit 53 (built in the terminal device 29a) to input a kana or numerical code (step S27). Then, the auxiliary information determining means 65
3, it is determined whether the input data is numerical data or not. If this result is YES, search execution means 6
6 executes a search in the auxiliary dictionary 7l using the numerical code (
Step S29). The process moves to step S31. Further, if the result of step S28 is NO, the search execution means 66
A search of the kana-kanji conversion dictionary 70 is performed using the kana (step S30), and the process moves to step S31. Step S31
Then, it is determined whether there is a corresponding item. If the result is YES, the correction data determining means 67 determines whether there is only one type of corresponding item (step S33). If the result is NO, display screen 5
4a (built into the terminal device 29a) selection candidate display field 39a
Then, selection candidates are displayed (step S34). The operator then selects a desired candidate. The correction data determining means 67 displays the selected candidate in a corresponding display column of the display screen 54a, for example, the transmission data display column 34b (step S36), and handles this kana character as transmission data. Here, the operator
The user presses the send key provided on the screen (step S37). The processor 51 assembles a transmission message to be sent to the host device 16 (step S38), drives the communication control unit 55 to transmit the message to the host device 16 (step S39), and ends the process.

Note that if the result of step S23 is NO, step S26 is immediately executed. Further, if the determination of NO is made in step S31,
An error message indicating that there is no corresponding item (kana characters) is displayed on the display screen 54a, and the process returns to step S27. If YES is determined in step S33, step S36 is immediately executed.

As explained above, when the character recognition device 50 of the present invention obtains transmission data based on image data that cannot be recognized by the recognition means 60, there is no need to input all the names of kanji displayed as image data. .

The character recognition device of the present invention is not limited to the above embodiments.

In the example, the explanation was given using a financial institution's money transfer business as an example, but the recognition is not limited to only the financial institution name (bank name) or branch name. For example, auxiliary information can also be used in a system that creates an address management file This can be easily applied by using postal codes, preset address codes, etc.

(Effects of the Invention) The character recognition device of the present invention configured as described above eliminates the need to manually input the entire name when recognizing characters (kanji) that cannot be recognized due to typographical errors or messy entries.

Therefore, it is possible to reduce the time and effort involved in inputting data and to execute processing quickly. Furthermore, since the amount of characters to be input is reduced, it is also possible to prevent input errors from occurring.
