Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to character processing devices such as word processors and electronic computers, and particularly to a processing function for characters that are not frequently used and are not standard equipment in the system (hereinafter referred to as external characters).

The character types used in conventional word processors, etc. are frequently used characters such as educational kanji, common kanji, common kanji, JIS C6226 Level 1, and JIS C6226.
There are characters such as the second level that are used less frequently.

Generally, word processors handle the above character types differently depending on their frequency of use. In other words, frequently used character types can be input using normal input methods (e.g. kana-kanji conversion).
Character types that are used less frequently are input using special input means (for example, Kuten code input using the JIS Kuten table).

The handling is differentiated based on the frequency of use depending on the primary tank.

■Supporting even characters that are less frequently used increases memory capacity and file capacity, which is uneconomical.

(■In many cases, operators do not know how to read characters that are used infrequently, and it is difficult to input them using kana-kanji conversion input.

In order to support characters that are used infrequently, it is necessary to prepare a character font (character generator: hereinafter also referred to as CG) in addition to the table for inputting kuten. For example, if a character is composed of 24 x 24 dots, CG requires 72 bytes per character.
00 characters takes approximately 144 bytes, which is a very large capacity.

Therefore, in the prior art, a method is used in which these character fonts are stored in an external memory and retrieved when necessary, but this method also has the disadvantage that the CG must always be stored in the external memory. . In other words, always having large files available in external storage is
This is not preferable because it limits the capacity of other processing programs, document files, etc.

Therefore, I recently created a special CG floppy.

Call the characters in the CG floppy to the character font area (external character area) in internal memory using a specific method.

A commonly used method is to display and print characters using the character font area.

In this method, it is sufficient to secure an area in the internal memory for characters that are used infrequently (approximately 100 characters at most).

The method for specifying characters in the CG floppy is as follows.

■Specify the selection mode for external characters (less frequently used characters 1, usually JISC6226 level 2).

■Insert the CG floppy instead of the system floppy that was previously installed.

■Find the desired external character from the JIS Kuten table and input its Kuten code.

Displays the external character specified by the 0 kuten code on the display device and waits for a confirmation message to be input.

■When a confirmation message is input, the specified external character is stored in the external character area of internal memory.

The external characters stored in the internal memory in this way can be recalled by inputting the Kuten code again on the editing screen.

If the external character to be called is not in the external character area, another special character (a external character mark) is displayed instead.

However, the number of characters to be registered in the external character area in internal memory is
Limited by the capacity of the external character area.

When creating a document that includes a large number of external characters, there will be a shortage of capacity, and some external characters will not be able to be stored in the external character area. In the conventional technology, when there is insufficient capacity, the operator decides to delete unnecessary characters in the character area and add other characters to the empty area.
There are cases where necessary external characters are deleted. If you deleted a necessary external character, the conventional technology does not have a means to automatically recover it, so it is necessary to register the deleted external character again.

An object of the present invention is to solve the problems of the prior art as described above, and to provide a character processing device that is capable of printing and displaying custom characters that have been deleted from the custom character area due to capacity constraints in the custom character area without having to re-enter them. The purpose is to share the following.

Configuration In order to achieve the above object, the configuration of the present invention includes a first character generator that constantly stores character fonts of frequently used characters, and a first character generator that constantly stores character fonts of frequently used characters, and fonts of less frequently used characters that are read from an external storage device as needed. In a character processing device that includes a second character generator that stores a character phono 1- of a character and an editing memory that stores a character code corresponding to an input character, when printing or displaying, If the character font of a character that is used less frequently is not stored in the second character generator, the character font of the character that is used less frequently is automatically downloaded from the external storage device based on the character code stored in the editing memory. Reads the character font of low characters.

A feature of the present invention is that a storage means is provided in the second character generator.

Hereinafter, the configuration of the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram of a character processing device according to an embodiment of the present invention.

In FIG. 1, ■ is a printing device, 2 is a display device, 3 is an input device, 4 is a CG floppy (external storage table Wi), 5 is a print control unit, 6 is a document memory (2 collection memory, 7
is the display control unit, 8 is the phono extraction oil outlet, 9 is the standard CG,
10 is a video Rp, M (editing memory), 11 is a custom character CG (a private character area), 12 is a custom character selection control section, and 13 is an external storage control section.

Register and delete external characters as follows.

First, the operator specifies the external character selection mode using the input device 3, and sets the CG floppy 4 in place of the system floppy that has been set so far. At this time, a display screen as shown in FIG. 2 appears on the display device 2. This is a screen that sequentially displays the custom characters marked W&'ft in the custom character area II.Next, when you enter the Kuten code (character code) of the new custom character you want to register, the custom character selection control section L2 acquires the relative position in the CG floppy 4 from the Kuten code and instructs the external storage control unit 13 to read the external character font of the corresponding external character.

The external character fonts read from the CG floppy 4 are as follows.

It is stored in the external character area 11.

In the example in Figure 2, "Dog J, 4" corresponding to external character code 4801 is
806-compatible r'J, 5301-compatible "Yakuji", 6201
The corresponding characters ``Yura J'' and ``Don'', which correspond to 4807, have already been registered in the external character area 11, and the external character code 6801 corresponding to the external character ``Kakei'' has just been entered in Kuten, and the external character code 6801 and the corresponding character code 6801 are displayed in the guide area. , the corresponding external character ``筺''
is displayed and is waiting for confirmation from the operator.

When the operator inputs OK information in this state, the external character "Kate" is added to the external character area 11.

Deletion is performed by setting the deletion mode and inputting the Kuten code of the external character to be deleted.

When editing a document, to edit a custom character, enter the code of the custom character in the document.
Display device! For example, if the private character font of the private character corresponding to the input Kuten code is registered in the private character area 11, the El collection screen of No. 2 will display 1, for example.

Like the external character "I" on the editing screen shown in Figure 3.

The external characters corresponding to the entered Kuten code are displayed, and if they are not registered, as shown in Figure 4.

At the editing position corresponding to the input Kuten code.

The external character mark ■ is displayed. However, in the case of 1ih when the external character mark ■ is displayed, - is also used for editing memory.

That is, 1 document memory 6 and 1 video RAM 10
Similarly to the character codes of editing characters other than private characters, the character codes of private characters (kuten codes) are stored.

When you need to formally represent the external characters indicated by the external character mark, that is, when you want to print them or check them on the display screen,
In the next chestnut area, output the edited content including the custom characters that support the custom character mark.

The process will be explained below using the flowchart shown in FIG.

Note that FIG. 5 shows the case of printing.

First, print preparations such as setting the print mode and specifying the print document and print range are performed (501), and the printing device i! Initialize 1 (502), i! At step k, the print control section 5 searches the document memory 6 (503), reads out the character code of the specified part, and transfers it to the font extraction section 8 (504).
), the font extraction unit 8 sequentially searches the sent character codes one by one and distinguishes between standard characters and custom characters (505
).

In the case of m quasi-characters, the font extraction unit 8 calculates the corresponding address of the standard cG9 from the standard character code, directly accesses the standard CG9, and extracts the character font of the standard character (505, 511).

In the case of a private character, the font extraction unit 8 sequentially searches the code storage section of the private character CG11 (50G) and checks whether the private character font corresponding to the transferred private character code is registered in the private character CGII.

If it is registered, extract the external character font (
507.5 L L), if it is not registered, the font extraction unit 8 sends the private character code to the private character selection control unit 12.
(508) - After controlling the external character selection system 61 L2, the external character storage control unit 13 reads the corresponding external character font from the CG floppy 4 and stores it in the external character area 11 (509.510).

At this time, if there is no empty area in the private character area 11, an erasable address in the private character area 11 is calculated using a specific logic, the private character font stored at that address is deleted, and the CG floppy 4 is placed in that area. Stores the read new external character font. As an example of the above-mentioned specific logic, for example, a method of configuring the external character area 11 as shown in FIG. 6 can be considered. In other words, the external character code fill 1
a, usage frequency s11 in addition to external character font 1illb
There is a method of providing c and replacing the least frequently used ones first. On the other side, a method of replacing the oldest registrations may be considered.

The font extraction unit 8 extracts the newly registered external character font (510, 511).

The font extraction unit 8 sequentially transfers the character fonts (standard character fonts or custom character fonts) extracted in this way to the print control unit 5 and stores them in the character buffer (512).

The printing device rLl is controlled to print when the number of character fonts in the character buffer reaches one line (513, 514, 515).

The above explained the case of printing, but if you want to display the actual custom character that corresponds to the custom character mark at the time of editing, input device 3
By pressing a specific key, a private character font corresponding to the private character mark is automatically registered in the private character area 11 and displayed in the same manner. However, at this time, the 1 display control unit 7 changes the external character code in the video RAMIO to 11?
Have sex.

In this way, in this embodiment, when you want to print or display a custom character font that is not registered in the custom character area 11,
Since it is automatically registered from the CG floppy 4, the capacity of the external character area 11 required the capacity of multiple documents in the past, but in this embodiment, at least the external characters of the part to be printed or displayed It only needs to be enough to store information. Furthermore, even if a custom character font is once deleted from the custom character area 11, it is automatically registered and restored without having to be re-inputted when necessary. To take it to the extreme, in this embodiment, as long as the custom character code is input during the f4 collection, the custom character font will be automatically transferred to the CG floppy disk based on the custom character code in the document memory 6 or video RAM 10 when printing or displaying. 4 and registered in the external character area 11, there is no need for the operator to register any external characters.

Note that the search target is separately stored fixed phrases and phrases.

It is possible to extend this to user registered words as well.

Effects As explained above, according to the character processing device of the present invention,
It becomes possible to print and display a custom character that has been deleted from the custom character area due to the capacity limitation of the custom character area without having to re-enter it.
