Description

DETAILED DESCRIPTION OF THE INVENTION [Field] The present invention relates to a character processing device having an indentation function.

In a character processing device having a high display cost, it is difficult to edit a character string by using indentation to separate the character strings.

Further, in a character processing device having an indentation processing function, it is not possible to check the WA command on the display screen to determine the number of digits from the left margin of the set indentation, and it is only possible to check it after printing.

Furthermore, even when changing the setting position of an indent once input, it is difficult to edit the character string because the amount iM cannot be done only on the display screen.

〔the purpose〕

SUMMARY OF THE INVENTION In view of the above-mentioned points, an object of the present invention is to provide an office character processing device that allows easy confirmation of indentation position information set on a display screen.

Another object of the present invention is to enable efficient character string editing by making it possible to easily confirm the changed indent setting position even after the manually set indent setting position has been changed. An object of the present invention is to provide a character processing device that can perform the following functions.

〔explanation〕

An embodiment of the present invention will be described with reference to the figures.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

The CPU is a microprocessor that makes logical decisions and the like. B
L is a pass line, which is an address bus that specifies the address of each input/output memory, a bidirectional data bus used for various data transfers, read/write of each memory, reception of interleaved data, data center timing, etc. It consists of control lines used to transmit information. KB is the keyboard and the operator is here to input various characters, =! 7hi gives commands to the device.

KBC is a keyboard controller, keyboard K
It encodes the manually input data from B and sends out an included signal to the pass line BL. LCI)
is a liquid crystal display that can display characters, control symbols, etc. over 15 columns per line. RM is a refresh memory that stores codes such as characters to be displayed.

The CG is a gear raffle generator, and the character button is also stored. LCI)C records the character code to be displayed in the refresh memory RM using the display controller, converts the character code stored in the refresh memory RMK into a pattern and displays it using the gear generator CG. Controls the liquid crystal display LC]). I70M is a read-only memory in which a control program to be described later is stored.

) tAM is a random access memory and is used for temporary storage of various data. SB is a sentence buffer, in which characters entered manually from the keyboard and codes of control signals are sequentially stored. ◇DP is a display start position pointer, which is a pointer that indicates the beginning of the part of the sentence buffer SB that should be displayed. . CR is a cursor register and indicates in which part of the liquid crystal display LCD the cursor is located. For example, if the cursor is at the left end of the display screen, 1
1 takes a value of 15 when it is at the right end. 1-11 is a head position register, which stores a value indicating the digit of the current position of the printer head counting from the left margin.

IT must be an indentation key, and an intent code corresponding to the specified number of digits is stored.

For example, Figure 5 shows the state of the indent table IT. When indent is specified on the second line from the left margin, code α+1 is specified, and when indent is specified on line 4 from the left margin, code α+1 is specified. Code α+3 is assigned. P
O is a pointer and the cursor is in the sentence buffer SB
Data indicating which digit is to be specified is stored.

A schematic diagram of the key tops of the keyboard KB is shown in FIG. C
K is a group of letters, alphanumeric characters, and kana characters.

It consists of a movement key, a carmol right movement key, and an indentation key. FK2 is a group of printer-related keys, consisting of a printer head left movement key, a printer head right movement key, and a print start key.

Indentation input processing according to the embodiment of the present invention with the above configuration will be explained.

First, FIG. 3(1) shows an example of the display screen, and FIG. 3(2) shows the print form desired to be output. The character string input from the keyboard KB is displayed sequentially from the left end as shown in FIG. 3(1). Here, ( is a control symbol that represents a line feed.

When creating a document, as shown in FIG. 3(2), it may be necessary to perform a crotch, for example, starting from the second line.

In such cases, use indentation for editing purposes.

◇ shown in FIG. 3 (1) is a control symbol indicating indentation and indicates that printing starts at the third line.

In the example shown in FIG. 3, the operator inputs 0 after completing the manual input of the characters on the line [-1] and starts inputting the characters on the second line. Here, we want to start the third sheath printing on the second line, so we set the indent to the third line. Therefore, the printer head is moved to the third line using the printer head dye transfer key. After moving the plink head, press the indent key. Here, an indent mark ◇ is displayed on the display screen.

Continue to enter characters in the same way as in the first line and enter the characters in Figure 5 (1).
A display screen like this will be obtained.

Furthermore, when changing the indentation set in the third line of the second line from the third line to the fourth line, see Figure 4 (1).
Move the cursor to any position in the 21jth character string as shown in . Then, to specify the fourth line, use the printer head movement key to move the printer head to the fourth column, and press the indent key. By performing the above operations, a display screen as shown in FIG. 4(1) is obtained. By pressing the print key here, the
The print result shown in is obtained.

The above operation will be explained in detail with reference to the flowchart shown in FIG. 6, 2M7.

FIG. 6 (1) is a diagram showing the printer head right movement process;
FIG. 6(2) is a diagram showing the leftward movement process of the printer head. It is assumed that after the apparatus is powered on, the printer head is set on the left margin, that is, at the left end of the movement range, and 1 is set in the printer head position register HR.

When the head right movement key is pressed, in step S7.l.1, the value of the head position register HIt is compared with the number of digits of the right margin set in advance as the number of digits from the left margin, and the value of the HR is compared. If the value is small, step S7
・If not, return to 1 or 2. Step S7
・In 1 and 2, printer controller PRO 1: Sends a command to move the lid head to the right outside the digit. P) The LC controls the printer PK according to this command, and the printer head moves one digit to the right. Next, the process advances to steps S7.1.3. In steps S7.1.3, the value of the head position register HR is crossed by 1 and the value is incremented by l.

When the head left movement key is pressed, the position shown in Fig. 6 (2
) is controlled according to the flowchart.

In step S7.2.l, the value of the head position register HR is compared with the number of digits of the left margin, that is, 0, and if the value of the head position register HR is large, step S7.2.l
to, otherwise return. Step S7.2.
2, head 1 to printer controller p lt c
Sends a command to move left by digits. PkC controls printer PR according to this command, and the printer head moves one digit to the left. Next, do a step turn.

Next, the process when the indent key is pressed will be explained according to the flowchart of FIG.

When the indent key is pressed, processing is executed in order from step S8.1. In step S8.l, in the process of determining where on the sentence buffer SB the cursor position corresponds, 1 is subtracted from the sum of the display destination order position pointer LlP and the cursor register CRO value, and the sentence buffer SH The relative address from the beginning of is calculated and this value is stored in pointer PO. Step S8・
In step 2, it is checked whether the value of the pointer is O, that is, whether the cursor is at the beginning. If it is O, the process proceeds to step S8.8; otherwise, the process proceeds to step S8.3. Step S8・
In step 3, if the SBO inner valley content indicated by the pointer is a line feed code, the process advances to step S8.7; otherwise, the process advances to step S8.4. In step S8.4, the contents of the sentence indicated by the pointer PO are changed to 1J1.
If the code matches the indentation code in the indentation table I1' of FIG. 5, step S8
- Go to step S8.6 otherwise go to step S8.5. In step S8.5, the pointer is decremented by 1 and the process proceeds to step S8.2.

Return to step 0 In the indent replacement process of S8/6, the head position register HR is referred to and the code of the indent table IT shown in FIG. 5 corresponding to the value of I-IR is written to the position indicated by the pointer of the sentence buffer S13. Go to step S8/9 ff1tro At step S8/7, the pointer is incremented by 1, and step S8/
Proceed to step 8. In step 5S-S, the head position register (IR) is referred to and the code of the indent table shown in FIG. 5 corresponding to the value is inserted into the position 4 indicated by the pointer of the sentence buffer SB.

Then, the process proceeds to steps S8 and 9, where the value of the current pointer P (J) is set to the display start position pointer DP, and the display processing is performed by referring to the character generator CG for the character code and the indent table I 'I' for the indent code. Go ahead, the cent indentation will be displayed on all sides of Wfi
I can make an edict.

Regarding the printing process to obtain the result shown in Figure 4 (2) for the indent code set through the above process, for example, when an indent code is detected, the indent table IT is This can be easily realized by referencing the code and replacing the number of digits corresponding to the code with spaces.

[Other Examples]

In this example, regarding the specification of the indent setting position,
Although the digits are specified by moving the printer head, other methods may be used, such as manually inputting the number of digits from the keyboard. Furthermore, even if the display screen is not a display device that displays only one line, but a display device that can display multiple lines such as a CR'f' display, the indentation setting digit can be set at a glance, so the present invention can be used. The main idea remains intact.

Furthermore, it is easy to display not only the set number of indent digits, but also the set digits, the number of blank digits, etc.

〔effect〕

As explained above, according to the present invention, by displaying the d information of an indent at the same time as displaying the indent, for example, the number of digits of the set indent can be confirmed, and the set position can be changed. Since the changed setting position can be easily confirmed even after the change, document creation can be done efficiently.
