Abstract

PURPOSE:To improve the operability, by constituting so that a line feed code is not inserted except the time of outputting to a printer, and a blank area of the line end is always set to a writable state. CONSTITUTION:When a prescribed line read-out signal is sent to a line read- out part 13 from a CPU 11, the line read-out part 13 obtains area information in a text buffer corresponding to its prescribed line from a line control part 12, reads out contents of the text buffer and sends them to a CPU 11. When it is decided by a blank deciding part 14 that the line end of the prescribed line is a blank area, the CPU 11 sends the prescribed line to a line feed code write part 15, in which a line feed code is written in the blank area of the line end of the prescribed line, and when its writing ends, said prescribed line is returned to the CPU 11. Subsequently, the prescribed line is sent out to a printer and its line is printed by the printer.

Description

[Detailed description of the invention] The present invention relates to the wordpress σ set f4=.

＠Figure 1 is a block diagram showing the configuration of a typical word processor. (31 is a text buffer in which the text to be processed is stored; (4) is the signal 6 from the control unit (2); based on the signal 6, the text YIi in the text buffer 131 is displayed on the Ii surface;
T1151 is a printer that prints the text in the text buffer 1 (3I) on paper based on the signal a from the control unit (21).

Normally, the above-mentioned busic (5;) has a mechanism that prints every line. Therefore, in order to cause the printer 151 to perform the line feed operation W, which is rejected by the word processor, it has a line feed code as one of the C2 control codes. The refusal code is displayed as a line feed mark (6) on the screen (4&) as shown in Figure 2 (2).

In addition, 171 in Figure 2 is the margin i7 that defines the area that can be inserted into oRljit (4m), and the number of characters in one line C; is defined by the width between such margins. The two C characters at the end of the line in the area are jammed.

When -, it is natural that a line break will occur in step (5) even without the above line feed call r.

However, when the above-mentioned line break mark is displayed, there is a problem in that the area after the line break mark (6) becomes a non-writable area. Therefore, in Figure 182, if you want to add a sentence after the line break mark 16), delete the above line break mark, and then add the desired sentence (- again, add the line break mark after such a sentence. The extremely troublesome operation of writing χ was required.

The present invention has been made in view of these points, and will be explained below based on the drawings.

4IJ5 is a block circuit diagram showing part (2) of a boot processor according to an embodiment of the present invention.

In the figure, the un control unit (21c) is the OPU that controls the entire WIC word processor, 113 is the text buffer + 311: I @ the line management F that handles the line information of the supplied text, The information to decline is the storage location of each f1 of Joki Bunso in text buffer f31,
There are the number of characters that can be inserted into each line, the number of lines in a sentence, etc.

01 is a line output unit that reads out the predetermined nature of the text in the text buffer d3 based on the signal from OPU+Jυ;
The designation of the continuation line to be N is made from 0PU1111,
Based on such a line designation signal, the line management unit (reads out the contents of line 17J from the buffer (31) T, field a indicates whether the end of the line read from the line reading unit a group 2 is a blank area or not. r
The result is χOP U[l14. This is a margin judgment unit to send, and this judgment unit executes the above processing when a signal is input from the CP UGII. Write a line feed code at the end of the line.

The fourth cause is a flowchart for explaining the operation of the circuit shown in Figure 5 of the tth century, and the operation sounds will be explained below based on the flowchart 1.

First, in step 81, a print signal is sent from the keyboard tl+ to CtPUoll. 0PU (111) When such a signal is input, the following steps 82 to a5 are executed and the sentences in the text buffer +31 are sequentially sent to the printer (51) line by line.

In step 82, the process of continuing to continue one line of the text in the text buffer (31) is performed by first sending a predetermined line continuation signal from the line reading section i to the opo (1υ).
From the line reading unit G, the area information in the text buffer (3) corresponding to the predetermined property is obtained from the line management unit a, and based on this information (-, the contents of the text buffer (31) > 1 consecutive output OP U (11C-send.

When this process is completed, 0PU(lυ) executes 15 steps.

In step 83, it is determined whether the end of the line of the above-mentioned predetermined property sent by 0PU (1) is a margin area.Such a judgment is made by first performing the above-mentioned predetermined property from OPυaυ in the margin judgment section a2-advance judgment 1. .The result is sent to opvan.As a result, if it is determined that the specified line end is not a blank area, O
PU (1m executes s5 steps Y, and when it is determined that the predetermined line end is a margin area, 0PU (19 executes 84 steps i).

At step 84, the predetermined line end 1; line feed code is written. Such processing is performed from 0PU (In to the above predetermined line Y
The code is sent to the line feed code storage section a9, and then, at the line feed code storage section (19 (=), two or more line codes are written in the margin area C at the end of the line of the above-mentioned predetermined property. When such writing is completed, the above-mentioned predetermined property is 0PU (IDC; returned.

When the above processing is completed, opv (11B executes 85 steps).

In step @5, the predetermined line from which the opva reference:fIA has been read out is sent to the t printer (5), and the line 1 is printed by the printer (5). When such processing is completed, OP
tyan is a6x type t'w line.

In step 86, it is determined whether the predetermined condition is the last line in the sentence. In this determination, the line currently being processed, that is, the rank in the given text, is sent from the CPU an to the line management group a4=, and the line management unit (11: Comparing with the number of rowsC
2, and the results are sent to CPUan. 01
'U (At 111, the next step to be executed is selected based on the result. In other words, if the above predetermined property is the last line, the program ends; otherwise, the step 8R is executed again. Execute.

Next is the flow v01 of the above flowchart? Picture Fii (41
) The processing of a sentence consisting of three lines displayed as shown in Figure 45 (2) will be explained in more detail. In the figure, Qυ is a margin mark to simplify the explanation (:, and in reality, this No such display is made, and the same parts in the figure as in FIG. 2 are given the same numbers.

When a print signal is input in step 81, the first
The line should be output to the printer +51 (:g:0PU(
1υ works. Since the end of the first line is a blank area, this operation is executed in 82.85.84.85 steps, and as shown in FIG.
Output to the convolution printer (5). After that, 86 steps are executed. Since the first line is not the last line, the program returns to Step 82.

In step B2, the next -242nd line is read out.The end of the second line is a blank area, so il! S, 84. Execute 85 steps and output to the printer as shown in Figure 6 BC: The end of the second line (includes two-many line mark @Yll).Then, since the second line is not the last line, repeat steps 82 from 86. Return to

In step B2, the %$5 line is continued. Since the end of the prefecture 3 line is not a margin area, the program executes 85.85 step i and outputs the third line as it is to the printer (50-).

Also, since the third line is the final line, the program ends in 86 steps.

Therefore, in this embodiment, the text buffer (text in 31)
Printer 15) 1m row by row by executing a loop consisting of 282.83.84, I5.86 steps or a loop consisting of 82, tx5.85.86 steps.
Output.

In this example, 451! When two or more margin areas from the end of the C2 line are pressurized consecutively, as in the second line of i3 (: also line feed mark +23 is 1161m). : As shown, the left end of the continuous gold-white area (-) may be changed to write a new line mark.

As is clear from the above description, in the word processor of the present invention, a line feed code is not inserted except when outputting to a printer, so the margin area at the end of a line is always in the C: writable state, thus improving the productivity of large fnks.
