Abstract

PURPOSE:To attain the collective centering processing with plural lines within a document range by designating said range where the centering is desired in the centering processing. CONSTITUTION:A document including the character strings, etc., supplied by a key input device 1 is stored in a document memory device 2. Then this stored document is partially designated by a range designating device 3. This partial document designated with a range is shifted toward the center position of a line by a shift processor 4. The result of this centering shift is outputted to the device 2 and the contents of the device 2 are displayed on a display device 5 via a display controller 6.

In this character processing device, a document such as a character string inputted by a key input device 1 is stored in a document storage device 2, a part of the document is specified by a range specifying device 3, and a part of the document is specified by a movement processing device 4. Centering movement is performed on the document within the specified range, the result of the centering movement is output to the document storage device 2, and its contents are displayed on the display device 5 by the display control device 6.

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

In the configuration shown in Figure 2, the CPU is a microprocessor that performs arithmetic operations and logical judgments for character processing, and is connected to these buses via the address bus ^B, control bus CB, and data bus OB. Control each component.

2B is a keyboard on which are arranged various keys for inputting characters, symbols, etc., and key inputs for instructing various functions of character processing for these key inputs.

Address bus AB transfers address signals indicating components to be controlled by microprocessor CPjl. Control bus CB is microprocessor C
Control signals for each component to be controlled by Pu are exchanged with each of these components. The data bus DB transfers data between each component.

The ROM is a read-only memory, and stores in advance control procedures by the microprocessor CPU, such as those shown in FIGS. 6 to 8.

The DBOF is a document memory that stores documents such as character strings input from the keyboard using B or the like.

FIG. 3 shows an example of the arrangement of such a document memory DBUF. In this embodiment, it is assumed that this document memory DBUF has a storage capacity of 10 characters×8 lines.

Documents such as character strings and symbols entered on the keyboard from B etc. are stored in the document memory D[1lIF, and displayed on the display CRT in the same positional relationship.

RAM is a random access memory and is used to temporarily store various data from each component. In this embodiment, the following parameters are set.

Number of moving columns TRX Range specification start column address 5ACRX Range specification start row address SMCIIY Range specification end column address E8CRX Range specification end row address EACrlY First character string address in range specification line 5CCRX Last character string address in range specification line ECCRX The centering save buffer TRBIJFDISK is a memory for storing standard documents, manages created documents, and can recall stored documents 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 cursor column source. YCR is a cursor row register and stores the row coordinates of the cursor.

CRTC is a CIIT controller under whose control the cursor register CR and document memory DBII
The contents stored in F are displayed on a display device CRT using a cathode tube or a liquid crystal display device.

CG is a character generator, and the display CR
It generates character signals such as letters, symbols, and cursors to be displayed on the T.

FIG. 4 shows the initial state of the document memory DBUF. By moving the cursor to the position of ■■ and specifying the address indicating the row and column of the range to be centered in this order, Specify the centering range. Then, by inputting a key to the centering key CT on the keyboard KB, centering is executed in the designated range, resulting in the state shown in FIG. 5.

FIG. 6 is a general flowchart showing an example of the control procedure of this embodiment. The above embodiment will be explained using such a flowchart. In FIG. 6, in step Sl, initial settings are performed when the power is turned on, and devices connected to the common buses CB, DB, and AB are put into a usable state. In step s2, a key input from B on the keyboard is detected, and in the next step S3, each process is selected according to the input key.

Here, step S4 is a cursor movement process, and step S5 is a range designation process. Step S6 is
This is centering processing, the details of which will be described later. Step S7 is other input and editing processing.

The initial setting, key input, cursor movement, and range designation methods in steps 51 to S5 are realized by known techniques, and detailed explanations thereof will be omitted.

FIG. 7 is a flowchart showing an example of the control procedure for processing when the centering key CT is pressed after the range to be centered is specified with the cursor as shown in FIG. 4 in step S5. . Here, the row address y and column address X of the document buffer DBOF are
The contents of the position indicated by are expressed as (x, y).

First, in step 5S-1, the value of the range specification start row address 5ACRY is substituted for y. Next step 56-2
Now, the values of the first character string address 5CCRX in the range specification line and the last character string address ECCnX in the range specification line are set. The details will be described later.

Furthermore, in step 56-3, the character string from the first character string address 5Ctl:RX in the range specification line of the y line to the last character string address ECCRX in the range specification line is stored in the centering save buffer TIIBUF.

In step 56-4, the number of moving columns TIIX is calculated.

The calculation is as follows.

1 =E8 to nX -5ACRX + 1m
= ECCRX -5CCRX + 1, then -m TRX = [-] ([P/Q] indicates the integer part of the quotient when P is divided by Q.) Next, in step 56-5, y Row range specification start row address 5ACIIY to range specification end column address EA
Fill in up to CIIX with blank code. Next step 5
6-6, centering save buffer T in RAM
The number of characters stored in the string stored in RBIIF is m.
Document buffer DBUF horizontally from (x+TRX, y)
I'll transfer it inside. In step 56-7, it is checked whether y is equal to the range specified end row address EACIIY;
If they are equal, end the process; if not, step 5
In step 6-8, 1 is added to y, and the process returns to step 56-2.

FIG. 8 is a flowchart showing details of step 56-2 described above. First, in step 5S-2-1, the range specification start column address 5ACRX is substituted for X, and in the next step 56-2-2, it is determined whether (x, y) is a blank code. If it is not a blank code, step 56-2
-3, and if it is a blank code, select step 56-2-4. In step 56-2-4, it is checked whether or not X is equal to the range specified end column address EACI (X). If they are equal, it means that there is no character code in the y line in the specified range, so step 56 in FIG. -7. On the other hand, if they are not equal, go to step 5B-2-5, where X has 1
, and then returns to step 56-2-2.

In step 56-2-3, the value of X is assigned to the first character string address 5ccnx in the range specification line. Furthermore, in step 56-2-6, the range specified end column address EA is set to X.
CRX is substituted, and in the next step 56-2, (x,
y) is a blank code. If it is not a blank code, the process proceeds to step 56-2-9, and if it is a blank code, step 5B-2-8 is selected. Step 56-2-8
Then, after subtracting X or 61, return to step 56-2-7. In the other step 56-2-9, the value of X is assigned to the final character string address EC(:RX) in the range specification line.

In the above-described embodiment, the centering execution key CT is used to instruct the start of the centering process, but the start of the centering process may also be instructed by other means, such as a command.

[Effects of the Invention] As is clear from the above, according to the present invention, by specifying a document range for which centering is desired, multiple lines within that range can be centered at once, resulting in faster editing processing. can be realized.
