Reference numeral 8 denotes a text buffer for one line, which stores the information of the character string of one line of the line designated by the line designating means 5 and the information of the position of the format mark of the line. Then, the information stored in the text buffer 8 for one line is given to the format mark position detecting means 10 and the character string extracting means 12.

Reference numeral 9 denotes a cursor position designating means, which detects and stores the position of the cursor at that time. The detection result of the cursor position by the cursor position designating means 9 is given to the format mark position detecting means 10.

The format mark position detecting means 10 detects the position of the format mark of the line on which the cursor is located in accordance with the information on the cursor position given from the cursor position indicating means 9 and the information given from the text buffer 8 for one line. The position of the format mark detected by the format mark position detecting means 10 is given to the format mark position storing means 11 and stored therein.

The format mark position storage means 11 is a format mark position detection means 10
The position of the format mark given from is stored and given to the character string extracting means 12 and the character arranging means 15.

The character string extracting means 12 extracts a character string included between the format marks from the information of the character string of one row given from the text buffer 8 for one line and the information of the format mark given from the format mark position storage means 11. Then, the information is given to the character spacing determination means 13.

The character spacing determination means 13 detects the spacing of each character from the information of the character string provided by the character string extraction means 12, and supplies this to the character string generation means 14.

The character string generation means 14 outputs the information on the character spacing given from the character spacing determination means 13 and the information given from the editing instruction storage means 4 for instructing editing, that is, the signal "0" for the centering insertion processing, and the centering deletion If it is processing, a new character string is generated according to the signal "1". The character string generated by the character string generating means 14 is given to the character arranging means 15.

The character arranging means 15 calculates the character position for positioning the character string given from the character string generating means 14 at the center according to the position information of the format mark given from the format mark position storing means 11, and In accordance with the result, each character is displayed on the display means 16 and the text buffer control unit 6

In addition, at this time, a predetermined signal is given from the key determination means 3 to the control section 2, whereby the control section 2 specifies the line on which the cursor is located at that time, that is, the line instruction means 5 gives an instruction. In accordance with the line position information, the text buffer control unit 6 reads the character string information of the corresponding line from the text buffer 7, and then stores this for one line in the text buffer 8 (step S4).

Then, the format mark position detecting means 10 detects the position of the format mark of the line from the stored contents of the text buffer 8 for one line and the cursor position detected by the cursor position indicating means 9, and stores the format mark position. It is stored in the means 11 (step S5). Further, the character string extracting means 12 extracts the character string included between the format marks according to the information stored in the text buffer 8 for one line and the format mark position storing means 11, and the result is the character spacing determining means 13 To detect character spacing information (step S6).

The information on the character spacing detected by the character spacing determination means 13 is given to the character string generation means 14, and the character string generation means 14 creates new information according to this and the editing instruction information given from the editing instruction storage means 4. Generate a string (step S
7).

For example, when the centering insertion key K1 is operated, the character string generation means 14 inserts a space for one character between characters, and when the centering deletion key K2 is operated, the character string generation means 14 is operated. Deletes one space between characters. Then, the character arrangement means 15 calculates the character device according to the information of the generated character string and the information stored in the format mark position storage means 11, displays it on the display means 16, and also gives it to the text buffer control section 6. And further stored in the text buffer 7 (step S8).

FIG. 1 is a schematic diagram showing the state of document editing according to the above-mentioned procedure. "" Indicates a left format mark, "" indicates a right format mark, Indicates a space for one character, respectively. In the example shown here, when the character string "ABC" as shown in FIG. 1 (a) is simply centered, the state as shown in FIG. 1 (b) is displayed. But the centering insert key
When instructing centering insertion by operating K1,
As shown in FIG. 1 (c), a space for one character is automatically inserted between each character, and then centering is performed. Further, if a centering insertion instruction is given again, as shown in FIG. 1 (d), two blanks are inserted between each character and the centering state is maintained.

On the contrary, when the centering deletion is instructed in the state shown in FIG. 1 (d), the spaces between the characters are deleted one by one and centered as shown in FIG. 1 (c).
When the centering deletion is instructed again from this state, as shown in FIG. 1 (b), the spaces between the respective characters are further deleted one by one and the characters are centered.

It should be noted that although the processing associated with centering has been described in the above embodiment, it goes without saying that the present invention is also applicable to processing associated with other character string arrangements such as right justification.
