Abstract

PURPOSE:To simply attain the horizontal and vertical writing methods as well as the combination of both methods by setting previously a cursor in the prescribed shift direction in a document compiling mode and therefore securing an automatic shift of the cursor is response to the shift of the character input in said shift direction of the cursor. CONSTITUTION:The shift direction of a cursor is previously stored in a register CTR through a keyboard. If the input of characters is performed with the lower shift designated, it is decided that the contents of the cursor shift direction stored in the register CTR is defined as CTR = 2. Then it is decided whether or not a front cursor line address YCR is equal to the maximum digit number MAXY, i.e., whether the cursor can move downward or not. In case YCR not equal to MAXY is secured, '1' is added to the cursor line register UCR to move the cursor to a place lower by one line While it is decided whether a cursor digit register XCR is equal to 1 or not, e.g., whether the cursor can move to the left or not in case of YCR = MAXY. Hereafter the same procedure is repeated for each input of characters.

[For production]

According to the present invention, by specifying in advance the direction in which you want the cursor to move, the cursor can also be automatically moved in the same way as the character input moves in that direction. Not only can you easily create any type of document, but you can also edit documents more quickly because there is no need for complicated cursor operations when inserting some vertical documents into a horizontal document or when creating tabulations. I can do it.

〔Example〕

Embodiments of the present invention will be described in detail and specifically below based on the drawings.

FIG. 1 shows the configuration of an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes key input means, which includes a cursor movement direction indicating key CT. Reference numeral 2 denotes a cursor control means that stores the cursor movement direction specified by the cursor movement direction instruction key CTK and controls the cursor to move in the corresponding movement direction.

Symbol 3 is a character input from key input means 1.

This is display control means that controls the display of symbols, cursors, etc. on the display 4.

As shown in FIG. 1, the key input means 1 instructs the direction of cursor movement, and the cursor control means 2 stores the result. Thereafter, when characters, symbols, etc. are input by the key input means 1, the cursor control means 2 and display control means 3 output the display of characters, symbols, etc. and cursor movement to the display 4.

FIG. 2 shows another embodiment of the character processing device of the present invention.

In the illustrated configuration, the CPU is a microprocessor that performs calculations and logical judgments for character processing, and connects the address bus AB, control bus CO, and data bus DB.
control each component connected to those paths.

Address bus AB transfers address signals indicating components to be controlled by the microprocessor CPU. Control bus CB is microprocessor CP
Control signals of each component to be controlled by U are transferred. The data bus DB transfers data between each component.

The ROM is a read-only memory, and stores control procedures by the microprocessor CPU, such as those shown in FIGS. 4 and 5.

Also, IIAM is a random access memory, which is used to temporarily store various data from each of the four components.

A keyboard KB has a few keys for inputting characters and symbols, and keys for instructing various functions to the character processing device, and a cursor movement direction instruction key CT is also arranged on the keyboard KB.

CTR is a cursor movement direction register and stores the cursor movement direction designated by the cursor movement direction instruction key CT.

MAXX is a document maximum digit number register, and stores the number of characters in one line determined by the document size setting. MAXY is a document maximum line number register, and stores the number of lines on one page. PAG is a page register, and stores the page where the cursor is located.

DISK is a memory for storing standard documents and manages created documents, and saved documents are called up by instructions from B on the keyboard.

CR is the cursor register. The contents of the cursor register CR can be read and written under control from the microprocessor CPU. XCR is a cursor column register and stores the column coordinates of the cursor. YCR is a cursor row register and stores the row coordinates of the cursor.

BUF is a buffer memory and stores character information etc. input from the keyboard KB.

A CRT is a display device using a cathode tube, a liquid crystal display, or the like.

CRTC is a CRT controller, and displays the contents stored in the cursor register CR and buffer memory BUF on the display CRT.

CG is a character generator and display device C
It generates character signals such as characters, symbols, and cursors to be displayed on the RT.

FIG. 3 is a diagram showing an example of the arrangement of the keyboard KB. In this embodiment, in addition to the alphabet keys ANK, a cursor movement direction instruction key CTK for instructing the movement direction of the cursor is arranged on the keyboard B.

Next, an example of the control procedure in this embodiment is shown in the flowcharts of FIGS. 4 and 5.

FIG. 4 shows an example of a processing procedure for instructing the cursor movement direction.

In step S1, if the input key is the cursor movement direction instruction key CTK, the process proceeds to step S2, and the cursor movement direction register CTR is set to 1 if the right direction is specified, and 1 if the downward direction is specified. 2 is stored, 3 is stored when the left direction is specified, and 4 is stored when the upward direction is specified.

In step S1, if the input key is not a key on the CT, the process advances to step S3 and normal processing is performed.

FIG. 5 shows an example of cursor movement processing after inputting documents such as characters and symbols.

Characters, symbols, etc. input from the keyboard KB are displayed at the current cursor position on the display CRT in step 511.

The next step 512 erases the cursor. Since the method of displaying and erasing characters, symbols, cursors, etc. on the display device CRT can be realized by known means, the explanation thereof will be omitted here.

In step 513, the cursor movement direction register C
It is determined whether the content stored in TH is 1.2 or 3.4. If 1, ie, movement to the right, proceed to step 514; if 2, ie, movement downward, proceed to step 515; if 3, ie, movement to the left, proceed to step 516; and 4, ie, move to the left.
If the cursor is moved upward, the process advances to step 517, and cursor movement processing in each direction is executed.

Since cursor movement processing in each direction can be realized by similar processing, in FIG. 5, the cursor movement direction register C
Only the case of TR=2, i.e. downward movement is shown in detail; for other directions simply steps 514, 51
It will be shown only as 6,517.

In step 515, it is determined whether the previous cursor row address YCR is equal to the maximum number of digits MAXY, that is, whether the cursor can be moved downward. If YCR≠MAXY, proceed to step S18, and if YCR-MAXY, proceed to step S19.

In step 518, 1 is added to the cursor line register YCH in order to move the cursor eight positions down one line.

In step SL9, it is determined whether the cursor digit register xCn is 1, that is, whether the cursor can be moved to the left. When XCR=1, that is, the cursor is at the bottom left of the page, proceed to step 520;
If ≠1, the process advances to step 521.

In step 520, in order to move the cursor to the upper right of the next page, 1 is added to the contents of page register PAG, 1 is assigned to the contents of cursor line register YCH, and the maximum number of digits MAXX is assigned to cursor digit register XCR. .

In step 521, in order to move the cursor to the first shuttle with the left finger, 1 is assigned to the contents of the cursor line register YCH,
and decrements the contents of the cursor digit register XCR by 1.

After completing the processing in step 520 or 521, the process proceeds to step 522, where the cursor row register YCR
and cursor digit register XCR page register PAG
A cursor moved according to the value of is displayed on the display CRT.

In the above-mentioned embodiment, the direction of cursor movement was specified by providing a special CTK key, but instead of doing so, the function of the CTK key was given to the existing key by double function. Alternatively, instructions may be given through commands or other methods.

Additionally, if the cursor cannot be moved in the cursor movement direction (for example, when moving downward and the cursor is on the last line), it is possible to determine this and perform movement processing other than this example. be.

〔Effect of the invention〕

As is clear from the above, according to the present invention, by specifying in advance the direction in which the cursor is to be moved,
The cursor can also be automatically moved as you input characters in that direction, so you can use it for both horizontal and vertical documents. '! Not only can it be created, but it also eliminates the need for complicated cursor operations when inserting a portion of a vertically written document into a horizontally written document or when tabulating a table, allowing for faster document editing.
