〔Example〕

Hereinafter, embodiments in which the present invention is applied to a word processor will be described in detail with reference to the drawings.

FIG. 5 is a block diagram of a word processor.

In this figure, a processing device 401 is, for example, a microprocessor, and reads and executes processing programs stored in a program memory 402, and controls each processing program and transfers data via a pass line 411.

When characters constituting a sentence are input from the key input device 404, which is a data input device, the character code corresponding to the character is stored in the key code memory 403. The processing device 401 converts the input character code to a specified position on the display device 409 as document data and stores it in the document data storage memory 410, and also stores the character pattern corresponding to the input character code in the character generator memory. (hereinafter referred to as C, G, memory) 407, expands the bits into bit map memory 406, displays on display device 411 via display control circuit 408, and moves the cursor to the next input position.

If the input character code is a conversion function key, the character data entered up to the time of the conversion function key is converted by the Kana-Kan conversion dictionary 412, and then replaced with the character string corresponding to the conversion to convert the document data. Stored in storage memory 410. For the document data stored in the document data storage memory 410, character patterns corresponding to the character codes constituting the document data are read out from the C, a memory 407, bit-developed in the bitmap memory 406, and then sent via the display control circuit 408. and is displayed in the document display area on the display device 409.

FIG. 3 shows the structure of character data stored in the document data storage memory 410.

Character data is composed of character code information 201 and character modification information 202 for each character. The character code information 201 stores a unique code determined within the document editing device, and the character modification information 202 stores a unique code determined within the document editing device. is Mincho/Gothic phono]・information, character enlargement information such as horizontal/vertical/horizontal double,
Stores character compression information such as half-width/quarter-width, shading information, underline information, etc.

Next, a processing program by the processing device 401 will be explained with reference to FIGS. 2 and 3. The character string input process in step 101 is a process in which a character code to be synthesized is fetched from the key input device 404 and stored in the document data storage memory 410. In the character synthesis range designation process in step 102, the character synthesis range of the document data that has already been input in step 101 on the display device 409 is selected using the human input device 404.
This is a process in which the designated positions are stored in the key code memory 403 as two addresses (data positions in the document data storage memory 410). The range of character composition is
Specify the start and end positions of the string to be synthesized with the cursor. This designation method may be from the start position to the end position or from the end position to the start position. The character composition attribute setting process in step 103 reads the two character data positions, which are range designation information, from the key code memory 403, and converts the character data corresponding to the designated range into the character modification information 202 shown in FIG. This is the process of setting it as character synthesis control information. The character management information resetting process in step 104 is a process of correcting the length (number of characters) of the corresponding line managed in the document data storage memory 410 designated by character composition and storing it in the document data storage memory 410. Since the position of subsequent character data on the document changes accordingly, line management information is managed in the document data storage memory 410.

The page management information is corrected and the document data storage memory 410
to be memorized. Step 104 is a process for expressing a plurality of character strings specified in a range by character composition as one character. The editing information redisplay process in step 105 is a process for displaying the processing result of the document data modified in step 104 on the display device 409.

FIG. 4 shows an outline of the character synthesis process.

The display method when character composition is specified is step 10.
The display character string specified in step 6 is stored in the document data storage memory 41.
0 to the display data memory 413, and performs display initialization processing such as calculation of display position. At this time, the pattern synthesis memory 405 is also initialized (cleared to 0). Next, character data is extracted one character at a time from the extracted character string, and in step 107, character composition of the character modification information of the character data is determined. If the character composition attribute is not set, the process moves to step 108, and C and G are used as normal characters.

The corresponding character pattern is taken out from the memory 301, developed in the bitmap memory 303, and displayed on the display device 409. If the character composition attribute is set, step 1
09, the corresponding character pattern is taken out from the C, G and memory 301 and developed in the pattern synthesis memory 405 in OR mode.

In step 110, if there is a next character, it is checked whether a character composition attribute is set in the character modification information of the next character data, and if it is set, the next character pattern is composed. If there is no next character, or if the character composition attribute is not set for the next character data, the process moves to step 112, and the pattern composition memory 405
The character pattern created above is developed in the bitmap memory 303 and displayed on the 1 display device 409. At this time, the pattern synthesis memory 405 is initialized (cleared to 0) for the next character synthesis. When the display of one character is finished, the process moves to step 111, where it is checked whether the entire specified character string has been displayed, and if not, the next character data is analyzed.

One line of character string display ends when all specified characters are displayed.

This makes it possible to display composite characters. When printing a composite character, the data developed in the bitmap memory 303 at the time of display is developed into a print memory, and the data in the print memory is printed by a printing device, thereby making it possible to print the composite character. Further, it is also possible to use a bitmap memory 406 as the printing memory, and the bitmap memory 406 may be used by switching between display and printing.

In this embodiment, the pattern synthesis memory 4 is used for character synthesis.
05 is used, however, the bitmap memory 406 may also be used as a pattern synthesis memory and the synthesis pattern may be created on the bitmap memory 406. In this case, character strings in which character composition information is set are developed at the same location on the bitmap memory, and the character strings are developed in OR mode.

〔Effect of the invention〕

According to the present invention, character patterns that can be created by character synthesis not only allow document creation and one-gram intensive creation without creating and inputting new character patterns, but also allow instant confirmation of the synthesized pattern, This simplifies the pattern creation operation and enables display and printing on systems where character patterns are not registered.
