Abstract

PURPOSE:To change printing character size when executing the printing is stopped by inserting a printing stop code which becomes a command to stop the executing of printing between adjoining codes in a character string or any space of various types of character. CONSTITUTION:A character size controller 8, in accordance with command information from a command register 14, selects the supply of a character code to ordinary character CG16 or enlarged character CG17. If command information is an enlarged printing command, the character codes stored in a character buffer 9 upto the present moment are supplied to the enlarged character CG17 through a switching circuit 10. The character CG to which a character code is supplied outputs a dot pattern to a dot buffer 13, and the character code is temporarily held by the dot buffer 13. Then the code is output from a printer 7 through a printer drive circuit 15, printing a character positioned before a printing stop code SC. Later the character CG judges the ending of printing, and changes the printing size, if character data are present, thus designating anew the output size of a printing character which exists after the printing stop code SC.

Description

[Detailed Description of the Invention] (a) Industrial Application Field This invention is capable of printing text such as strings of characters created by various codes and characters in normal font size and larger enlarged font size. This paper relates to a method for changing the size of printed characters in a Japanese word processor that performs the following process, and in particular, the timing of the size change.

(B) Prior Art Conventionally, when printing, a method has been used in which the print character size is set in advance for each line. In other words, in enlarged printing, an enlargement code is input at the beginning of a line that requires enlargement, and only that one line is enlarged and printed.

(c) Problems to be solved by the invention However, with this method, when attempting to enlarge a text of two or more lines, the enlargement value is set not only for the first line but also for all lines after the second line. was necessary and the operation was troublesome. In other words, if there are two or more lines of text that require enlargement, you must add an enlargement code to all the relevant lines. It was impossible to expand.

This invention was made in view of the above circumstances, and when printing a change in the print character size or when printing is stopped by a print stop code inserted into a text that has not been created, the print character size The purpose of this paper is to provide a method for changing the print character size in a Japanese word processor, which allows the user to change the size of printed characters in a Japanese word processor.

(d) Means for Solving the Problems The configuration of the present invention is suitable for printing character strings formed by codes and various characters in normal size and in non-normal size N and M (but In a Japanese word processor that prints codes and various characters of size N times Inserting a print stop code that is a command to stop printing in between, and changing the print character size when printing is executed or when printing is stopped by the print stop code during printing. This is a method for changing the size of printed characters in Japanese word processors, which is characterized by the ability to change the size of printed characters.

(e) Operation When the print stop code is detected, the printing in progress is stopped and the print character size can be changed.

(F) EXAMPLES Hereinafter, examples of the present invention will be described in detail with reference to the drawings, but the present invention is not limited to the following examples.

What is not shown in FIG. 1 is a Japanese word processor (1
) is a block diagram showing the hardware configuration of.

Reference numeral (1) denotes a keyboard in which a character entry key-1 print key, a print character size selection key, a print stop code entry key, etc. are arranged in the order specified by, for example, JIS. +21 is a display means, for example a polar ray tube (hereinafter C
RT), etc., and displays character strings entered from the keyboard (1). (3) is a central control unit (hereinafter referred to as CPU), which is preferably a 1A BAT microprocessor, for example, an external storage device (4) with a floppy disk as a storage medium, and a kana-kanji conversion system consisting of a ROM. dictionary (hereinafter referred to as dictionary) +51

(Character pattern generation is controlled by the character code data and character size command supplied from 31, and the character buffer (9
), the character code stored in the character buffer (9) is transferred via the switching circuit 00) (111) to the character pattern generation circuit side, and a dot buffer that stores the character pattern supplied from the character pattern generation circuit (incorporated). ?(
13), a command register G41 iJ3 for storing the above character size command, and a printer drive circuit (151) are connected to each other.

The character pattern generation circuit (12) generates a corresponding character pattern from the character code supplied from the character buffer (9), and is, for example, a normal character generator that generates a dot pattern of 32x32 dots 1 to 1 of normal print characters. (Hereinafter referred to as ordinary characters CG and 1')
(161) and an enlarged character CG generator (hereinafter referred to as enlarged character CG) that generates a dot pattern twice the size of a normal character.
GO6) and enlarged character CGO7) are selected by a switching circuit (1010υ) activated by a character size command and connected to the character size controller (8). A print buffer that stores pattern data supplied from the controller (8)? (not shown) is built in, reads out data from this print buffer column by column, and outputs it to a printer (sword).

In the above configuration, a character string formed of codes and various characters, in other words, a Japanese sentence or an idiom indicating the title of the sentence, is input from the keyboard (1) and stored in the sentence buffer (6).

When inputting this text, etc., insert a print stop code, which is a command to stop printing, between adjacent symbols or various characters in the text, and store it in the text buffer (6) along with the text data. be done. The print stop code (SC) is
When editing a text once stored in the text buffer 7 (6), insertions and cancellations can be performed in the same way as inserting and canceling characters.

Next, the operation of this embodiment will be explained according to the flowchart shown in FIG.

First, the user specifies the print character size (Sl), which is an operation to specify the character pattern to be printed out, that is, enlarged characters or normal characters, using the keyboard (1).
. For enlarged characters, the enlargement values N and M are respectively N=1 and M=
2, and if it is a quadruple-width character, the enlargement values N and M are N=M=2, respectively.

Print character size information input from the keyboard (1) is sent to the CPU (31) and the character pattern controller (8).
) is stored as a font size command in the command register □□□) (command set) (S
2). Next, the user instructs the start of printing in the format set in Sl by operating the execution key on the keyboard (1) (print command) (83). By print command,
The print data (text data) held in the text buffer (6) is supplied to the character size controller (8) via the CP Ll (3) (print data read) (
84). When reading the print data starts, it is determined whether the print data supplied to the character size controller (8) is a print stop code (SC) (85), and further it is determined whether it is a line feed code (S6). . If the above print data is neither a print stop code (SC) nor a line feed code, that is, if the read code is a character code, the character code is stored in the character buffer (9
) (written into character code) (S7) and stored. To write the character code, write the print stop code (S
G) or until the line feed code is read out (84.85°86, S7).

Next, the case where the line feed code is read out in 86 will be explained.

Is the character code read out sequentially and a character buffer? (9)
When the line feed code is read in the process of being stored in the character buffer (9), the character code stored in the character buffer (9) up to this point is supplied to the character pattern generation circuit via the character size controller (8). Beforehand, the character size controller (8) determines whether to supply the character code to the normal character CG (161 or the enlarged character CGO7) according to the command information in the command register (141). (S8)
. If it is an enlarged print command at S8 (YES),
The character size controller (8) is a switching circuit (g)) (I
D and supplies the character code stored in the character buffer (9) to the enlarged character CG 07) (S9).

Or if it is not an enlarged print command in S8 (No
), the character code stored in the character buffer (9) is supplied to the normal character CG (16). Any character CG to which the character code has been supplied outputs a dot pattern corresponding to the character code to the dot buffer 03),
It is temporarily held in the dot buffer (13) and printed out via the printer drive circuit (15) (printer output) <811). After this, from 88 above, S
The steps up to step 11 are repeated to determine whether one line of characters has been printed (printing completed) (812).

If printing is finished (YES), determine whether there is next data (513), if there is (YES > 84).
Go back and print the next line. If there is no next line (N
O) Printing ends. The above is the operation when there is no print stop code (No in S5), but the print stop code (SC) is inserted in the text data, and the character codes are read out sequentially. ) The case where the print stop code (SC) is read out during the process of being stored in (YES at 85) will be explained.

First, the character size controller (8) selects the normal character CGO6 according to the command information in the command register 04).
] or the enlarged character CG (17) (314). If the command information is an enlarged print command (814, YES), the character code stored in the character buffer (9) up to this point is sent to the enlarged character CG Q7) via the character size controller (8).
(S15). Or, if it is not an enlarged print command (814, No), the character code of character buffer? (9) is the normal character CGff.
7) via the switching circuit [F] (81
6). The switching circuit [F] is the character size controller (8)
controlled by Any character CG to which the character code is supplied outputs a dot pattern corresponding to the character code to the dot buffer a3 via the switching circuit port υ and the character size controller (8), and the character code is temporarily held in the dot buffer 03. After that, printer drive circuit 0
5) and is printed out by the printer (7') (print output) (817). Then, steps 814 to 817 are repeated to print the character located before the print stop code (SG). After this, check whether printing is finished.8
1B), if finished (YES) print stop code (SC)
I need to determine whether there is character data located after 8.
19), if there is character data (YES), return to 81 and change the print size to print the print stop code (S
C) Respecify the output size of the existing printed characters. During this time, the printer (7'I) has stopped printing.If there is no character data in S1b (NO),
Printing ends.

As mentioned above, the print stop code (SC) is included in the text data.
) exists, the size of the printed characters can be changed by newly specifying the output size of subsequent printed characters each time. When a print stop code (SC) is added to a text, it is displayed on the CRT+21 as shown in FIG. 3, for example. The item shown in Figure 3 is an example in which a print stop code (SC) is inserted before and after one word, but it is also possible to separate a single clause with a print stop code (SC), or even to separate multiple clauses. By inserting the lines so as to separate the lines, it is possible to set enlarged values for a plurality of lines, that is, to perform enlarged printing.

(G) Effects of the Invention According to the present invention, the size of printed characters can be specified in units of characters or sentences, or in any range of multiple lines, and the Japanese word blog can be easily operated. A method for changing the print character size can be obtained.
