Description

[Detailed description of the invention] A system for displaying a character string including a character pattern created by a user, in which a different character pattern is newly created using the same identification code as a character pattern already used in the character string. This is a character pattern display method to warn you of the situation. When displaying a plurality of candidate characters for input character selection, characters in the above state are displayed in a different manner from other characters, such as in a different display color from other characters. By performing a subsequent appropriate operation to determine whether the new or old character pattern is to be valid, processing in the case of incorrect identification code specification is facilitated.

[Industrial application field]

, the present invention is a system that displays character strings including character patterns created by users, and when a new character pattern is created using the same identification code as a character pattern already used in the character string. The present invention relates to a character pattern display method for warning of such conditions.

For example, in an input terminal device for creating and inputting information provided to an image information system, character strings input from a keyboard are displayed on a display device such as a so-called CRT display device, and the input operation is performed while being monitored.

The display on the display device is based on a character pattern consisting of a so-called dot pattern or the like designated by an identification code corresponding to each character.

In many such systems, identification codes and character patterns (hereinafter referred to as standard character patterns) are prepared for characters such as kanji, kana, numbers, and symbols that are used as standard. For some other identification codes, users are allowed to create and register character patterns (hereinafter referred to as created character patterns).

Since the management of created character patterns is left to the user, it is desirable for the system to have an assistance function to prevent created character patterns from disappearing due to erroneous operations.

[Prior art and problems to be solved by the invention] FIG. 2 is a block diagram showing an example of the configuration of an input terminal device.

The processing unit 1 receives the code input from the keyboard 2, determines the identification code of the input character by a known method such as kana-kanji conversion, and sequentially configures the input character string in the character string buffer 4 of the main memory 3. .

The contents of the character string buffer 4 are sent by the processing unit 1 to the display control unit 5, and the display control unit 5 retrieves the corresponding character pattern from the standard character pattern memory 6 or created character pattern memory 7 based on the identification code of each character. and is displayed on the display section 8.

The standard character pattern 6 is configured using, for example, a read-only memory, and is a memory that fixedly holds various types of character patterns.

The created character pattern memory 7 is composed of a normal readable and writable so-called RAM, and can hold, for example, up to eight types of pairs of identification codes and character patterns of created character patterns loaded from the processing unit 1. The number of created character patterns that can be used simultaneously within one screen of the display section 8 is limited to eight types.

As one designation method for inputting characters of a created character pattern (hereinafter referred to as created characters), a method of displaying a dictionary is provided. At least, when inputting a created character of a created character pattern created separately as one character of an input character string for the first time, it is necessary to use the index display method.

The display of the dictionary is started by inputting, for example, "10" as the reading 8 of kana-kanji conversion from the keyboard 2, and then pressing the control key "Jibiki".

When the processing unit 1 receives the above specification, in step 15 of the process flowchart of FIG. Inspect, and if there is none, proceed to step 19.

In step 19, the storage device 9 such as a floppy disk is
Created character pattern table 10 read in advance from
The corresponding character pattern is read out and displayed.

If a character pattern is stored in the created character buffer 11, the character string buffer 4 is scanned in step 16 to check whether this character is currently displayed, and if there is no corresponding identification code in the character string buffer 4. For example, in step 17, the part of the identification code on the created character buffer 11 is erased, and then the process of step 19 is performed.

If the corresponding identification code is in character string buffer 4,
In step 18, the corresponding character pattern in the created character buffer is displayed.

The above process is repeated through step 20 to display, for example, 10 types of character patterns together with the numbers, for example, 1 to 9.0, at the bottom of the screen of the display unit 8, as shown in FIG. 3(a). . Note that the character pattern for this display is directly notified from the processing section 1 to the display control section 5 and displayed, separately from the created character pattern memory 7.

If the user finds a desired character among the 10 types of created characters displayed, the user inputs the number above it from the keyboard 2. If the desired character is not displayed, for example, the "Dictionary" key is input, and in that case, the processing unit 1 selects the 10 character patterns arranged next in the created character pattern table 10 in the same way as above. Display by control.

If the character to be created is selected by a number, processing unit 1
In step 21, it is checked whether the corresponding character pattern is already stored in the created character buffer 11 on the main memory 3 using the identification code of the specified created character pattern, and if it is already stored, it is stored as is. Ends the dictionary display process.

If the corresponding character pattern is not stored in the created character buffer 11, the process advances to step 22, where the specified character pattern is read from the created character pattern table 10,
It is written into the created character pattern memory 7 together with the identification code. Furthermore, in step 23, the pair of the same identification code and created character pattern is stored in the created character buffer 11, and the index display process is ended.

In the process of inputting as described above, if it becomes necessary to change or add to the created character pattern, use the control keys from the keyboard 2 manually to interrupt the input process and process the character pattern creation process. request.

When receiving this request, the processing unit 1 displays the dot pattern input by the user on the display unit 8 to create a character pattern, and when the process is completed, the character pattern is created based on the created character pattern. Character pattern table 10
The character pattern above corresponding to the specified identification code is rewritten and the process ends.

Now, when the input process is subsequently restarted, if the created character corresponding to the currently updated created character pattern has already been used and the previous character pattern has been written to the created character pattern memory 7, The previous pattern is displayed on the screen of the display section 8.

In order to change this display to a new character pattern, all the corresponding created characters on the screen are once erased by blanking manually or the like, and then the corresponding character pattern is displayed on the diagonal display and input again.

In response to this operation, the processing unit l erases character pattern pairs of unused created characters on the created character buffer 11 in the manner described above, and creates a state in which a new character pattern can be read from the created character pattern table 10. Make it.

The reason why the created character pattern is updated in this way is because if, for example, an incorrect identification code is specified, the previous character pattern with that identification code will be completely erased, making the recovery operation complicated. This is to facilitate recovery in such cases, in which case the character pattern creation process may simply be modified.

However, in the conventional method, if you make a mistake in specifying an identification code when creating a character pattern, and when you try to use that character pattern and perform index display processing, if that is the code that is being used, the previous character pattern will be There is a problem in that errors are only displayed once and cannot be detected immediately.

[Means for solving problems]

FIG. 2 is a process flowchart showing the configuration of the present invention.

The figure shows an improved flowchart of the character index display process in the processing unit 1, in which when the created character pattern of the identification code to be displayed is currently displayed, the presence or absence of a change in the character pattern is checked in step 30 of the process, As step 31, processing for changing the display type a is added.

[For production]

In the dictionary display process, the processing unit 1 performs steps 15 and 1.
6, it is checked whether the created character to be displayed as an index is actually displayed in the input character string.

If it is displayed, the process proceeds to step 30, where the character pattern in the created character buffer 11 is compared with the character pattern of the same identification code in the created character pattern table 10.

If both university patterns match, the character pattern in the created character buffer 11 is displayed as in the conventional case.

If the two character patterns are different, specify to change the display mode in step 31, and then proceed to the next step 1.
At step 8, the character pattern in the created character buffer 11 is displayed. Therefore, in this case, it can be shown that the character pattern for this character is about to be updated by displaying it differently from other characters.

The display mode may be changed by, for example, changing the display color or brightness.

〔Example〕

In FIG. 1, the same processing as the conventional method is executed except for steps 30 and 31.

As above, from keyboard 2, type r10J + "Jiku"
When the dictionary display process is started manually, the processing unit 1 checks in step 15 whether or not the character pattern of the identification code exists in the created character buffer 11 from the beginning of the identification code for the created character. Proceeding to step 19, the corresponding character pattern is read out from the created character pattern table 10 and displayed.

If a character pattern is stored in the created character buffer 11, the character string buffer 4 is scanned in step 16 to check whether this character is currently displayed, and if there is no corresponding identification code in the character string buffer 4. For example, in step 17, the part of the identification code on the created character buffer 11 is erased, and then the process of step 19 is performed.

If the corresponding identification code is found in the character string buffer 4, the process proceeds to step 30, where the character pattern in the created character buffer AE is compared with the character pattern of the same identification code in the created character pattern table 10.

If both character patterns match, the character pattern in the created character buffer 11 is displayed as in the conventional case.

If the two character patterns are different, specify to change the display mode in step 31, and then proceed to the next step 1.
At step 8, the character pattern in the created character buffer 11 is displayed. Display a can be changed by, for example, changing the display to yellow characters when the normal display color is green.

The above process is repeated through step 20 to display, for example, 10 types of character patterns as shown in FIG. 3(b).

For example, the created character "
For example, if a character pattern of ``〒'' is created by specifying the same identification code as ``冨'', and at least one ``冨'' is used in the character string on the screen, the character pattern as shown in the figure "〒" is not displayed, but "冨" is displayed in yellow (
Other characters may be displayed in green, for example).

〔Effect of the invention〕

As is clear from the above description, according to the present invention, in a character string input device including a character pattern created by a user, the operation when updating a character pattern is facilitated, and the device is made easier to use. There is.
