Reference numeral 7 denotes a display means for displaying document information inputted by the input means 1 and a cursor.

FIG. 2 shows an example of a circuit configuration in an embodiment of the present invention.

In FIG. 2, the CPU is a microprocessor that performs calculations for character processing, logical judgments, etc., and is connected to the address bus AB, control bus CB, and data bus 0B via Control each component.

Address bus AB transfers address signals indicating the components to be controlled by microprocessor CPII.

Microprocessor CP via control bus CB
Control signals for each component to be controlled by the mouth are exchanged with each component.

Data bus DB transfers data between each component.

The ROM is operated by the microprocessor CPU in Figures 4 to 5.
It is a read-only fixed memory that stores control procedures as shown in the figure, and KB is a keyboard for inputting characters, symbols, etc.

DBIIF is a document memory that stores document information input from the keyboard KB. This document memory DBUF
In this embodiment, a memory having a storage capacity of, for example, 10 characters x 5 lines is used. Characters or symbols entered from B on the keyboard are stored in document memory DBUF. This character or symbol is stored at a predetermined address corresponding to the position displayed on the display CRT. For example, RAM is 1
It is a random access memory that stores character information such as characters and symbols having a word length of 16 bits, and has a tab f standing flag register TBF connected to a cursor position address register CB. The DISK is a 6R storage device that stores document information.

OR is a cursor register, which is a memory for writing and reading cursor address data under the control of the microprocessor CPU.

The CRTC is a CRT controller, and displays the cursor position and character/symbol code contents stored in the cursor register CR and document memory DBUF, respectively, on a display device CRT such as a cathode ray tube or a liquid crystal display device.

CG is a character generator, which generates character signals such as characters, symbols, and cursors to be displayed on the display CRT.

FIG. 3 shows an example of the configuration and arrangement of the keyboard B in the embodiment of the present invention.

In FIG. 3, CIK is a group of various keys such as character keys and function keys for inputting documents, and GK is various cursor movement keys for moving the cursor in various directions. CTK is a specific character tab key that moves the cursor from the cursor position displayed on the CRT to the next position of a predetermined character.

FIG. 4 shows an example of a control procedure according to an embodiment of the present invention. In FIG. 4, when the power is turned on, in step S1, the cursor position address CRA of the random access memory RAM is
and clear the tab stop position address memory TRAM. In step S2, the keyboard shown in FIG. 3 remains in a state of waiting for key input from 8. When a key is pressed, the process proceeds to step S3, where the input key is determined, and one of steps 54 to 511 is performed depending on the determination result.

Here, in step S4, character input processing is performed to store document information such as input characters and symbols into the document memory DBUF. The detailed procedure of this process is shown in FIG. In step S5, a search process is performed to search for a predetermined character string or the like.

In step S6, predetermined character conversion processing is performed. In step S7, cursor movement processing is performed to move the cursor. In step S8, a specific character tab process is performed in which the cursor is moved to the next position of the specified character position to which the cursor was moved in step S7, and the detailed processing procedure is shown in FIG.

In step S9, an insertion process for inserting characters, symbols, etc. into the document is performed, and in step StO, a process for deleting characters and symbols is performed. In step 511, other input and editing processes are performed.

After performing the processing in steps 54 to Sll, the process returns to the key input waiting state (step S2).

FIG. 5 shows an example of a processing procedure when characters, symbols, etc. are input from the keyboard KB in step S4 of FIG.

In FIG. 5, first in step 520, the character code of the input character is stored in the document memory DBUF. In the next step 521, it is determined whether the input character code is a specific character, such as a ruled line code, and if not, the character input process in step S4 is ended.

If it is determined in step 521 that it is the input character code or ruled line code, the DB of that ruled line code
A flag indicating that it is a ruled line code, for example, °°1, is stored in the storage area of the flag register TBF corresponding to the address position next to the address of IIF.

The address position of the flag register TBF where this flag 1'° is stored becomes the tab setting value.

FIG. 6 shows an example of the specific character tab processing procedure in step S8.

In FIG. 6, when a specific character tab processing instruction is given, in step 530, the cursor position indicated by the cursor register CR is transferred to the cursor position address register CRA.

Next, in step 531, it is determined whether the tab stop position flag of the address indicated by the cursor register CRA is 1°'. If TBF is "t", the tab is set at the address specified by the CIA, so the process advances to step 534.

If the tab stop position flag is not 1", 1 is added to the value of CIA (step 532), and further step S3
At step 3, it is determined whether the value of CIA exceeds the final address of data buffer DBUF. If it exceeds,
Assuming that no tab stop position has been found, the process ends without moving the cursor.

If it is determined in step S33 that CRA does not exceed the final address of DBIIF, step S33
Return to 31. Through steps S31-533 described above, either the first tab stop position that appears after the current cursor position is found, or the CIA exceeds the final address of the document memory [1BUF] is satisfied. These processes will be repeated until.

When it is determined in step 531 that the tab position flag TBF of the address indicated by CRA is set, the cursor is further moved to the position indicated by CRA in step 534, and the process is terminated. In the above embodiment, a specific character was used as a ruled line, but other characters or symbols that often require digit alignment may also be used, such as the yen symbol for "°°\" or the decimal point symbol for "゛". It's obvious that it's good.

[Effects of the Invention] As explained above, according to the character processing device of the present invention, the cursor movement in the table is moved by a predetermined logarithm distance from the specific character set in advance for automatic change by pressing the specific character tab key. The cursor can be moved to the tab stop position, which allows the cursor to be moved with fewer keystrokes, resulting in faster keystroke operations.
