Abstract

PURPOSE:To improve operability and to increase a document production processing speed with a character processor, by applying at least one of spelling verifying and spelling correcting process to an input character string. CONSTITUTION:A RAM 3 includes a line buffer area to store input codes and an information recording area needed for spelling verifying and spelling correcting functions. A spelling verifying/correcting boat SVC 4 gives the spelling check to the character string transferred from a CPU 1 via a BUS and informs this checking result to the CPU 1. At the same time, the correct character string candidate is sent to the CPU 1 for character string containing misspelling by an instruction of the CPU 1. Thus both spelling verifying and correcting functions can be applied to the input character string. Then the operability is improved and the document production processing speed is increased with a character processor.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character processing device, and more particularly to a character processing device having a function of detecting spelling errors and providing correct spelling candidates.

[Conventional technology]

Conventionally, an electronic typewriter is a typical example of this type of device. Electronic typewriters have character, pie, and character after modes in which printing is performed for each key manually, and 1.
There is a line/pie/line mode in which line key input is displayed on the display and printing is triggered by the return key or space key input in the hot zone.

By the way, the detection of spelling errors (hereinafter referred to as spelling verification) is performed by manually inputting a key that separates a single word such as the space key, and then detecting the continuation of the words that have been input and displayed before. is performed on the string. Also, in line bar line mode,
By moving the cursor on the display, this is also done for one line of characters that have already been input.

Currently, devices that provide correct spelling candidates for detected spelling errors (hereinafter referred to as spelling correct) only work for character strings displayed on an unprinted display in line bar line mode. .

[Problem that the invention is trying to solve] However,
Conventional character processing devices cannot perform spelling correction on already printed character strings, and have the following drawbacks.

(1) In character pie character mode,
Unable to spell correct.

(2) In the line-pie-line mode, spelling correction cannot be performed on the character string immediately before the key that triggers printing is input because the character string is printed.

Furthermore, the above-mentioned spelling verification is also disadvantageous in that it is not performed on previously printed character strings except for the last printed character string.

Therefore, for character strings that have already been printed, the user has to discover spelling errors himself and correct them using conventional correction functions.

〔the purpose〕

The present invention solves such problems and performs spelling verification and spelling verification even for character strings that have already been input.
The object of the present invention is to provide a character processing device that can perform document creation and editing with high efficiency by improving operability by making it possible to perform one or fewer corrections.

[Means for solving the problem (and operation)] In order to achieve the above object, the character processing device according to the present invention has the following steps:
When the carrier is moved to a character string that has already been printed, means for spelling verification of the character string by referring to the character string stored in the storage unit corresponding to the carrier position, and spelling verification of the character string with correct spelling. The apparatus includes at least one means for correcting.

Figures 5 to 8 are flowcharts showing examples of spelling verification and spelling correct processing procedures according to this embodiment, and Figures 9 to 12 are displays of a printed document 1 before and after spelling verification and spelling correct. FIG. 3 is an explanatory diagram for explaining a document. Line buffer area 9
FIG. 9 shows a print string before spelling verification, which is printed according to the print information stored in . 19-21
indicates the carrier position, and 19 indicates the final input position. As is clear from the figure, it goes without saying that the apparatus of the present invention can accurately position the carrier at a printed character string several lines in front of the position of the carrier. Examples of spelling verification and spelling correct when the carrier is moved to 21.21 will be explained with reference to FIGS. 5 to 8.

When the carrier is moved from 19 to 20 using the carrier movement key 14a-14i, information on the address position of the carrier on the line buffer area is stored in the carrier position information 10. Here, step S in Fig. 5a
1, spelling verify execution mode is on (1)
Determine whether KS is off (0), and if it is off, exit without spelling verification. If it is on (1), the process advances to step S2. In step S2, the line buffer area 9 corresponding to the address of the carrier position information 10 is
The character code is read and the process proceeds to step S3. In step S3, it is determined whether the internal code read in step S2 is a code constituting a character string such as alphabetic characters or a code indicating a delimiter of a character string such as a space or a symbol character. If the carrier position is 20, the internal code indicates the character code "C'," and "C" is a code that constitutes a character string, so you exit from the spelling verification function.If you move the carrier to 21, Since the internal code read in step S2 indicates a space, and a space is a delimiter between character strings, the process advances to step S4.From step S4 onwards, the explanation will be given assuming that the carrier position is 21.

In step S4, the character string in front of the space that is the delimiter of the character string at the carrier position 21 is transferred to the svc board 4.
The process then proceeds to step s5. Here, “contr
sct," is transferred. Step S5 reads the determination result from the svc board 5 and determines whether the spelling is correct. If the spelling is correct, the spelling verification function is exited. In this case, the spelling is incorrect, so step S6 In step s6, the buzzer 8 notifies the operator of the spelling error, and the process proceeds to step S7.In step s7, it is determined whether or not the collect key 17b has been input, and if it has been input, the process proceeds to step S8.Other keys is input, the spelling correct function is exited and the input key is executed.In step s8, the SVC board 4 is requested to provide a suggestion string for "contrsct," and the process proceeds to step s9. The character string is stored in the suggestion character string information area 11 on RAMa. Here, “contract
, " are stored. In S9, the suggestion string information 11 is read, and if the suggestion string exists, the process proceeds to step Sll. If it does not exist, the process proceeds to step SIO. In step SIO, the suggestion string information is sent to the buzzer 8. The spelling correct function process is terminated by notifying the operator that the spelling correct function does not exist.Step Sl
In l, the incorrectly spelled string (suspect string) is
8 is highlighted on the display, and the process proceeds to step S12. In step S12, it is stored in the suggestion character string information area 11. The string “contract,” is displayed on the LCD.
The information is displayed on the display 18, and the process proceeds to step S13. The display example shown on the LCD display 18 in FIG. 4 is a display example at this time. In the determination process of step S13, it is determined whether or not the ↓ key 14f has been input, and if no input has been made, the process advances to step S15. If it has been input, the process advances to step S14.

In step 314, a request is made to the SvC board 4 for the next candidate for the suggestion character string. The new suggestion string is stored in the suggestion string information 11, and the process returns to step S12. Note that it goes without saying that the candidates may be displayed one at a time or a plurality of candidates may be displayed at once and selected using the cursor. In the determination process of Si2, it is determined whether or not the ↑ key 14e has been input, and if it has not been input, the process advances to step S17. If it has been input, the process advances to step S16. Step S16
Now, a request is made to the SVC board 4 for the previous suggestion string candidate. A new suggestion string is stored in the suggestion string information 11, and the process returns to step S12. In the determination process of step S17, it is determined whether or not the ☆ key 17c indicating selection of a candidate has been input. If not, the process proceeds to step S19, and if it has been input, the process proceeds to step S18. In step 318, the suspect character string is corrected with the suggestion character string, and the spelling correct function is ended. Details of the correction function will be explained with reference to FIGS. 6 to 8. In step S19, it is determined whether or not the collect key 17b has been input, and if not, the process returns to step S13.

If it has been input, the process advances to step S20 to cancel the spelling correct function. In step S20, the LCD
The suspect character string highlighted on the display 18 is returned to the normal display, and the process proceeds to step S21. Step S2
In step 1, the suggestion character string displayed on the message line 21 of the LCD display 18 is erased, and the spelling correct function is canceled.

[Correction Processing 1] The flowchart in FIG. 6 is a detailed flowchart of the modification processing 1 in step S18 in FIG. FIG. 10 shows a printing result showing a specific example of correction process 1. In step S1 of FIG. 6, the character width of the suspect character string and the character width of the suggestion character string at the time of printing are compared to determine whether they are equal. If they are equal, proceed to step S2. If they are not equal, the process advances to step S7. In step S2, it is determined whether or not the suspect character string and the suggestion character string have the same width, but the printing pitches of different characters are the same. This is particularly effective for PS mode. If they are equal, the process proceeds to step S3; if they are not equal, the process proceeds to step S7. In step S3, the same process as step S20 in FIG. 5 is performed and the process proceeds to step S4. In step S4, the same process as step S20 in FIG. 5 is performed and the process proceeds to step S5. In step s5, the printed characters to be erased in the suspect character string are erased by PRT7, and the process proceeds to step S6. Figure 10 is an extracted version of the revised bulletin in Figure 9, and (a) in Figure 10 is an example of deletion (only "S" is deleted), and 22 indicates the position of the carrier. After moving to position 22, "S" is deleted.

In step s6, the characters to be printed in the suggestion string are printed on the PRT 7, the LCD display 18 is also rewritten, and the spelling correct process is completed. Figure 10 (b
) is an example of printing, 23.24 shows the carrier position, 23 is the same position as the carrier position where "S" was deleted in Fig. 10 (a), and after printing "a" , move the carrier to the carrier position at the time of spelling verification. 24 indicates a carrier position equivalent to 21 in FIG. The editing line of the LCD display 18 is also the 1st O.
The screen will be displayed in the same manner as in (b) of the figure. As explained above, FIG. 6 shows a method of minimizing the number of correction items when correcting a misspelled character string to a correctly spelled character string. Note that step S7 performs a different correction process and ends the spelling correct process.

[Correction Processing 2] The flowchart in FIG. 7 is a detailed flowchart of the modification processing 2 in step S7 in FIG. Fig. it is
This is a print result showing a specific example of correction processing 2.

In step S1 of FIG. 7, the effective character string width that can be inserted into the blank space after erasing the suspect character string is calculated, and the RA
It is stored in the character string width information 12 on Ma, and the process advances to step S2. The width of the string that can be inserted here means that when a string is inserted between the strings on the left and right of the suspect string, an appropriate amount of space is taken between the inserted string and the strings on the left and right, and the width of the string is printed. The character string width is calculated to the extent that it is not difficult to see. FIG. 11(a) is an example of a printed document subjected to spelling verification, in which the character string "t)inary" is a suspect character string. 25 indicates the suspect string width, 2
6 indicates the effective character string width calculated in step S1 and stored in the character string width information 12. In step S2, the print width of the suggestion character string is calculated using a reference pitch based on 10 pitches in the IO pitch mode, 12 pitches in the 12 pitch mode, and each character width in the PS mode, and the process proceeds to step S3. In the determination process of step S3, the suggestion character string width calculated in step S2 is compared with the character string width stored in the character string width information 12, and if the suggestion character string width is larger than the character string width information 12, step Proceed to S8. If the suggestion character string width is smaller than or equal to the character string width information 12, the process advances to step S4.

In step S4, the same process as step S20 in FIG. 5 is performed, and the process proceeds to step S5. In step S5, the same process as step S21 in FIG. 5 is performed, and the process proceeds to step S6.

In step S6, all suspect character strings are erased using PRT7, and the process proceeds to step S7. (b) in Figure 1O is a printing example in which the suspect character string "binary" is deleted,
Here, the word delete function that is already provided in the character processing device is used. In step S7, the suggestion character string is printed using the PRT7 using a word-to-word centering function that places a character string in the center of the blank space between the left and right character strings, which is already provided in the character processing device.
The LCD display 18 is also rewritten to complete the spelling correct process. FIG. 11(C) is an example of printing the suggestion character string "binary". In step S8, a different correction process is performed and the spelling correct process is ended.

[Correction Processing 3] The flowchart in FIG. 8 is a detailed flowchart of the modification processing 3 in step S8 in FIG. FIG. 12 shows a printing result showing a specific example of correction process 3. In step S1 of FIG. 8, the suggestion character string width calculation performed in step S2 of FIG.
The suggestion character string width is calculated using a pitch table as shown in FIG. 2 taken above, and the process proceeds to step S2. In the determination process of step S2, the suggestion character string width calculated in step St is compared with the character string width stored in the character string width information 12, and the suggestion character string width is larger than the character string width information 12. If so, the process advances to step S7, and if the suggestion character string width is smaller than or equal to the character string width information 12, the process advances to step S3. In step S3, the same process as step S20 in FIG. 5 is performed, and the process proceeds to step S4.

In step S4, the same process as step S21 in FIG. 5 is performed, and the process proceeds to step S5. In step S5, the same process as step S6 in FIG. 6 is performed and the process proceeds to step S6. In step S6, a suggestion character string is printed using the pitch table shown in FIG.
The CD display 18 is also rewritten to complete the spelling correct process. FIG. 12(a) is an example of a printed document subjected to spelling check, in which the character string "dsplayd" is a suspect character string. FIG. 12(b) shows the result of word erasing in step S5. (c in Figure 12)
) is an example of printing when the process is proceeded without performing the determination process in step S3 of FIG. 7, which will be explained in comparison with (d) of FIG. 12. In this printing example, the inserted suggestion character string and the character strings on the left and right are continuous, making it difficult to read as print. FIG. 12(d) shows the result of printing the suggestion character string in step S6 of FIG. 8 using the pitch table of FIG. 2. Step S7 uses a buzzer to notify the operator that the suggestion string cannot be printed, and step S7 in FIG.
Proceed to step 20.

In this way, according to this embodiment, spelling verification and spelling correct functions can be performed on printed documents, which greatly improves operability and speeds up document creation. Become.

[Other Examples]

By performing spelling verification during character input and setting a means to store position information of incorrectly spelled character strings, steps S1 to S shown in FIG.
By omitting the steps up to step 6 and pressing the collect key 17b in step S8 in FIG. 5, the carrier position 21 in FIG.
The operation can be simplified by automatically moving the carrier and proceeding with the processing from step S8 onward in FIG.

As another example, it is also possible to modify the document, instead of modifying each character string, to the entire line or part of the line where the suspect character string exists. Step S1 in Figure 7
to step S3, and in the process from step S1 to step S2 in FIG. 8, the second
Using the pitch table shown in the figure, calculate whether a suggestion string can be inserted in the direction of reducing the character spacing of all character strings in a row, and correct the document in the entire row or in a part of the row. This makes it effective for right-aligned printing that uniformly expands the space between character strings.

Furthermore, there is a space between the rightmost character string and the right margin in the line where the suspect character string exists, so that the increase in the number of characters due to replacing the suspect character string with the suggestion character string will fit within the space. If you do the math, you can correct the spelling by modifying the suspect string. Due to the above, the 8th
The possibility of proceeding to the buzzer process to notify that spelling correction is impossible in step S7 shown in the figure is reduced.

〔effect〕

As explained above, according to the present invention, it is possible to perform a spelling verification function on a document that has already been printed.
It is now possible to perform spelling correction in character mode, or for the character string immediately before the key that triggers printing in line/pie/line mode. By using the present invention, it becomes possible to automatically perform document correction processing that has previously been performed. This improves operability, saves paper, and provides a character processing device that can perform document creation and editing with high efficiency.
