When a customer changes his or her address, for example, the following operation control is performed.

The customer first selects an address change notification from the initial screen displayed on the display 52. The control unit 51 performs UUX& to update the screen and display guidance for notifying the change of address.

A magnetic card is inserted according to the instructions on the screen, and this is read by the magnetic card reader 59. Next, the screen prompts for inputting a password, so the user enters the password by hand from the tablet 53.

The handwritten input characters are compared with a recognition dictionary and read by the minicomputer 55.

When the account number entered from the tablet 53 and the account number read from the magnetic card reader 59 match, the control device 51 sends the old address, name, data, etc. from the host via the terminal controller 54 using the account number as a key. This is transferred and displayed on the display 52, and after confirming the displayed contents, the new address is input by hand from the tablet according to the instructions on the screen.

This handwritten input is checked against the recognition dictionary and read by the minicomputer 55. This recognition result is displayed on the display 52.

〔Example〕

An electronic bookkeeping table according to an embodiment of the present invention will be explained based on FIGS. 2 to 5.

Fig. 2 is a block diagram of one embodiment of the present invention, Fig. 3 is a flowchart explaining the overall process for an example of address change, Fig. 4 is a flowchart of handwriting input processing, and Fig. 5 is a second embodiment of the present invention. FIG. 2 is a partial diagram of an embodiment.

In FIG. 2, the same symbols as in FIG. 1 indicate the same parts.

The control device 1 comprehensively controls the electronic bookkeeping table of the present invention, and is composed of, for example, a personal computer,
It is equipped with a central processor unit (CPU) 20 and a memory 21, and is capable of, for example, displaying an initial screen on the display 2, controlling processing based on the selection, extracting characteristics of characters input to the tablet 3, It performs operation control such as input/output processing for the terminal controller 4 and reading of programs, recognition dictionaries, etc. for the first collation unit 8 and second collation unit 9 from the file 7.

The coupling circuit 5 performs TTL level conversion to enable multi-drop connection since multi-drop connection is not possible at the interface on the collation unit side of the control device 1. Thus, the coupling circuit 5 connects to the high-speed serial interface of the control device 1. The first verification section 8 and the second verification section 9 can be connected via.

Noting that the Centro interface on the printer side of the control unit R1 is 8-bit parallel, the Centro control circuit 6 uses the output of this Centro interface not only on the printer side but also on the first matching unit 8 and Second
This information is transmitted to the verification unit. The centro control circuit 6 is equipped with a processor 22 and a memory 25, which have a dictionary storage section 23 for dictionary storage processing and a program storage section 24 for program storage processing. Note that the processor 22
For example, a 32-bit MPU is used.

The centro control circuit 6 normally outputs print data for the printer 12 to the printer control unit 10, but when the system is started up, it loads programs into the first collation unit 8 and second collation unit 9, and loads different recognition dictionaries into each. Store the new DI. Note that the printer control unit 10 has a processor 10-0, a memory 1O-1, and a printer character font (C.

G) and a slip format image pattern, the printing image data is edited and transferred based on the bookkeeping data, and thereby the printer 12 issues slips of different sizes.

The first collation unit 8 recognizes characters input from the tablet 3, and includes a processor 26 and a memory 27. The memory 27 has a program area 27-L in which a program for operating the processor 26 is written. A work area 27-2 and a dictionary area 27-3 in which a recognition dictionary D0 necessary for recognizing handwritten characters is written are provided.

Note that this recognition dictionary D0 is for, for example, JIS first level kanji, numbers, alphabets, kana, katakana, etc.

The second matching section 9, like the first matching section 8, also recognizes characters input from the tablet 3, and is equipped with a processor 28 and a memory 29. However, the recognition dictionary written in the memory 29 is the first matching unit 8.
The recognition dictionary D0 is different from the recognition dictionary D0, and is composed of, for example, second-level kanji and other characters.

Further, a magnetic card reader control section 11 for controlling the magnetic card reader 13 is connected to the control device 1 through a 9600 BPS serial bit interface. The magnetic card reader 13 reads magnetic cards and passbooks brought by customers, and the read information is transmitted to the control device 1 via the magnetic card league control section 11.

Note that, as shown in FIG. 5, for example, the collation unit is composed of n sub-CPU boards 30-1 to 30-n, and recognition dictionaries ( 1) Divide ~(n) into approximately 1000 character units,
It is also possible to have a single task structure including a boot ROM, that is, a ROM and RAM in which a loading program is written, and to have a parallel processing configuration using multiple CPUs.

The operation of the present invention will be explained in the case of address change with reference to the flowcharts of FIGS. 3 and 4.

■ First, turn on the system. As a result, the control device 1 starts from the file 7 by first checking the first checking unit 8 and the second checking unit 9.
The programs for the centro control circuit 6 are sequentially read out and sent to the centro control circuit 6. After this program is once held in the memory 25, the program storage unit 24 stores it in the first collation unit 8.
and is sent to the second matching unit 9, and the memories 27 and 29
are stored in the respective program areas. In this way, the same program for recognition is stored from the file 7 into the first collation unit 8 and the second collation unit 9, respectively.

Then, the control device 1 reads out the recognition dictionary D0 for the first matching section 8 from the file 7 and sends it to the centro control circuit 6. The centro control circuit 6 temporarily holds this in the memory 25, and the dictionary storage section 23 sends it to the first collation section 8. As a result, the recognition dictionary D0 is stored in the memory 27 of the first matching section 8. Next, the control device 1 successively reads the recognition dictionary from the file 7 and sends it to the centro control circuit 6.

Similarly, this E'2 Hk dictionary is stored in the memory 29 of the second matching section 9.

(2) When the loading of programs, recognition dictionaries, etc. is completed in this way, the control device 1 displays an initial screen such as a process selection menu on the display 2.

■ When a customer changes their address with the bank, the customer selects ``Report address change'' by pointing to ``Address change'' from the process selection menu on the initial screen on the display 2. This updates the screen.

■ The customer inserts a magnetic card or passbook according to the instructions on the display 2 screen. As a result, the magnetic card reader 13 reads the personal identification number, account number, etc., and sends these to the control device 1 via the magnetic card league control section 11.

The control device 1 stores these in the memory 21.

■ Next, according to the screen instructions on Display 2, the customer
Enter the PIN number by hand. The handwritten input numbers are sent from the control device 1 to the coupling circuit 5, and are sent to the first matching section 8.
The second matching unit 9 simultaneously performs feature extraction and dictionary matching, but as described above, since the numbers are stored in the recognition dictionary D0, recognition candidates are transmitted from the first matching unit 8. (Only the PIN number is not displayed.) ■ When the correct PIN number is entered in this way and it matches the one held in the memory 21, the control device 1 transfers the held account number to the terminal controller. 4 to the host. Using this as a key, the host reads the old address, name data, etc., and transfers these via the terminal controller 4.

Since these old addresses and names are held in the memory 21 and displayed on the display 2, the customer presses "Yes" if these displays are correct.

In this way, the customer's old address, etc., is displayed and confirmed.

■ The customer inputs a new address by hand on the tablet 3 according to the instructions on the display 2 screen.

(2) Stroke data of this handwritten character is transmitted from the tablet 3 via the control device 1 to the coupling circuit 5, and then sent to the first verification section 8 and the second verification section 9. As a result, recognition processing for the flat and concave characters is performed in parallel in the first collation unit 8 and the second collation unit 9. Then, recognition candidates are sequentially displayed on the display 2 from the matching unit in which the recognition dictionary for that character is stored. If the displayed content is correct, the customer points to "Yes". In this way, the new address is displayed and confirmed. And the confirmed address is memory 21
is temporarily held.

■ Once you have entered the correct new address in this way,
The control device 1 sends this new address along with the account number, name, etc. to the printer control section 10, and the printer 12 prints out an address change notification.

■ After confirming this information message, the customer points to ``Yes,'' stamps the address change notification form, goes to the counter, and hands it to the bank employee.0 The bank employee accepts the form and processes the change of address. At this time, since the necessary data such as the new address is held in the memory 21, the process can be performed extremely easily by using this data.

Note that the processing of handwritten input in the password input, new address input, etc. will be briefly explained with reference to the fourth drawing.

■ When handwritten input is made to the tablet 3, the control device 1 echoes this stroke data back to the display 2 and displays it as is, while at the same time creating a character pattern for recognition, that is, a feature used for matching, in order to compress the amount of transferred data. Performs point extraction processing.

At this time, the coordinate data of the pen on the tablet 3 and the up-down information of the pen are sequentially transferred from the tablet 3 to the control device i1 at a rate of, for example, 50 to 150 points/second, so that the resolution of the tablet 3 and the display The dot density of 2 is converted by the control device 1 and used as data for display echo back. Then, the pen-up time is checked with a timer, and when a certain period of time has elapsed, it is considered that one character input into each character frame on the tablet 30 is completed.

o The character pattern of one character (data of feature points for one character) is sent from the control device 1 to the first matching unit 8 via the coupling circuit 5.
and the second matching unit 9, respectively. Therefore, dictionary matching is performed in parallel in the first matching section 8 and the second matching section 9 for the same character. At this time, as described above, since the recognition dictionaries Do and Dl are divided by recognition character classification, different characters are recognized, and a large number of characters are efficiently collated. Then, the obtained recognition result is responded to and transferred by polling from the control device 1 to the own station. The control device 1 displays the thus transferred recognition results in the input frame of the display 2, and if the displayed results are different, the customer points this out. By this pointing, the control device 1 displays the next candidate character in the input frame.

In this way, the input is completed when the display of all the input frames is confirmed (this is done by time monitoring using a timer) or when the customer indicates the end of the input.

Of course, the recognition speed may be somewhat slow (if this is acceptable, it is possible to increase the RAM capacity in the matching section and increase the number of characters in each recognition dictionary.) [Effects of the Invention] According to the present invention, the combination circuit Since the verification units are connected and operated in parallel, the recognition speed can be improved even if a conventional control device with a serial interface is used.

Since it does not use a minicomputer, it can be made smaller.

Moreover, when the system starts up, is it a centro system? Since the In circuit is used and programs and recognition dictionaries can be stored in each collating section through parallel output, operations can be started at high speed.

Furthermore, since the printer control is performed in parallel and separated from mechanical control and interface control, it is effective in improving processing speed and functionality. That is, it is possible to perform division of labor during print processing, such as using the processor in the Centro control circuit to develop one line or one page for printing, and exchanging character fonts using the processor in the printer control section.
