Abstract

PURPOSE:To improve operability of a character processor in a document print mode by using a memory device containing the hyphenation information to perform the automatic hyphenation. CONSTITUTION:When a hyphen character is included in the first half part, the line feed is carried out by the hyphen. If a word 'All-American', for exam ple, is divided into two parts 'All-Ame' and 'rican', the word is divided again into 'All-' and 'American' since a hyphen is included in the first half of the word. In case a hyphenation enable position is included in the first half although no hyphen character is included, the hyphenation is set at the most right side. While a word lapping process is carried out if no hyphen character nor hyphena tion enable position is included in the first half. For instance, a word 'type writer' is divided into 'ty' and 'pewriter', the word lapping process is carried out since 'ty' includes no hyphenation enable position. Then the line feed is carried out with a blank character part set before the word 'typewriter'. Thus the word 'typewriter' is moved to the next line.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a Roman document processing device, and particularly to a character processing device that can automatically perform hyphenation during printing using hyphenation information stored in an attached storage device. It is related to the device.

[Conventional technology]

When printing a document such as English text stored in a storage device, if the length of a word exceeds the line margin, you can use word wrap processing to carry over the word to the next line, or use hyphen processing to wrap the word. Hyphenation processing is required to separate it into two parts. Conventionally, in such cases, hyphenation processing or word wrap processing has been performed by the operator specifying the character position where the line break is desired each time.

[Problem that the invention seeks to solve]

However, the above method requires the operator to wait while the output device requests the line break position when printing a document, which is very inconvenient. In addition, when specifying the line break position, if the operator does not have knowledge of the positions where /S is allowed, there is a problem that hyphenation may be performed at a grammatically incorrect position. .

[Means for solving problems]

In order to compensate for the drawbacks of the above-mentioned conventional example, the present invention attaches a database containing information on correct hyphenation positions to the control device, automatically performs hyphenation when printing a stored document, and reduces the burden on the user. The purpose is to provide processing equipment.

In order to achieve this object, the present invention comprises control means for inserting and printing a hyphen and starting a line break when a word exceeds the printing width.

[Effect]

By providing this means, the hyphenation process at the end of a line can be easily performed without requiring the operator's help.

〔Example〕

Examples of the present invention will be described below. FIG. 1 is an external view of an electronic typewriter according to the present invention, and FIG. 2 is a schematic diagram of its main structure. ■ is an input device such as a keyboard that can input character data, change the right margin and left margin, and give printing instructions. 2
3 is a microprocessor that performs control, and 3 is a ROM containing a control program according to the flowchart shown in FIG.
, 4 is a RAM serving as a storage device, and 5 is an Sv or SC for extracting hyphenation information from an attached dictionary.

Sv stands for spelling verifier, and SC stands for spelling corrector, which reads hyphenation information from the dictionary 6 based on the spelling of the word and corrects it. 6 is a dictionary that stores correctly spelled words and possible insertion positions of hyphens in these words; for example, typewriting:
"type -write -ing" is stored. Figure 3 is a flowchart of automatic hyphenation processing. Figures 4 and 5 are examples of printing after automatic hyphenation processing.

In the electronic typewriter having the configuration shown in FIG. 2, a case will be described in which an English document stored in the document storage area TXT in the storage device RA i'vl is printed with automatic hyphenation. Character data input from the input device 1 is stored in the document storage area TXT.

Before starting printing, the operator previously determines the hyphenation processing mode using the keys on the input device 1.

There are two modes: manual and auto, and if manual is selected, the operator must specify the position for hyphenation at any time, as in the past, so the explanation will be omitted. Set the mode to auto for automatic hyphenation. This mode is stored in the mode storage area MD of RAM4.

After setting the mode, the user begins printing the stored document. This print command is sent to the control device 2 as a signal via the input device 1. The control device 2 that receives the signal decodes it and loads the corresponding control command from the ROM 3 of the storage device based on the result. The method for printing a stored document is as follows.

In the document stored in the document storage area TXT in the row of the storage device RAM, an area from the next character to be printed to the character that will be printed in one line is specified. The number of characters corresponding to -line is defined by the right margin storage area RM and the left margin storage area LM. This corresponds to the number of characters between the left margin and right margin of the format set for the document. For example, T his -is -an 1w e l
e c t r o n i c tw y p
e”+V r i t e r.

If the number of characters between the margins of a document starting with the - sentence is 22, and you try to print this document, the first 22
Specify the character area and print it.

In other words, print the character string Th1suisUan,=electronicLI, start a new line, and then type
ri te r.

The following documents are also separated into 22-character segments, and are repeatedly printed and line-feeded.

However, in the previous example, if the number of characters between the margins was 30, the first area specified would be T11jSU! 5uanpeleCtrOnjCLIt
ypeWrij and the word rtypewriterJ
can't fit on one line.In such a case, not only should the words be printed on two separate lines, but due to orthography rules, [type J and rerJ will be treated as two words. The rule is that words on two lines must be spelled with a hyphen, i.e. Th1
suis, Jan, -eleCtronic
L, typewrite -er, """ must be printed. This process is hyphenation. Also, if a short word such as "vSe" is separated by a hyphen, the word may become difficult to understand.

In such cases, a process called word wrap is used to create a new line at the last blank in a line.

In the previous example, Th1s, 1sLJan, -electronic
y p e w r i t e r , ・・・・・・
− becomes. By combining these two processes, text is printed line by line.

In order to process these automatically, the following three types of processing are necessary. This is determined by the state of the first half of the word divided into two parts.

Process 1: If the first half contains a hyphen character, perform a line break at the hyphen. For example, “A11-Am
The word erican J is "All-ame/ri"
canj is divided into two parts, since the first half contains a hyphen, it is rewritten as rAll-/AmericanJ and printed.

Process 2: There is no hyphen character in the first half, but if there is a position where hyphenation is possible, hyphenation is performed at the rightmost position. Regarding hyphenation, the position where hyphenation can be performed is determined depending on the word, and the position is searched using the dictionary 6. For example, “typ.
The word ewriter J is below. Do not hyphenate except at the two points shown.

type -write + er This is an orthographic rule. Therefore, this word "t"
If it is separated as y p e w r / i t e r J, it is re-separated at a position where hyphenation is possible in the first half.

In this example, it is r type/writerJ. But what if [typ e w r i t e /
If it is separated by r J, then it will be separated at the rightmost hyphenable point, so r ty p e W
r i t / e r j.

Process 3: If there is no hyphen character in the first half and there is no position where hyphenation is possible, word wrap processing is performed.

For example, if the word "ty / pewriter J" is separated, there is no hyphenable position in rtyJ, so word wrapping is performed and the word "typewriter
Break the line at the space character before J and type ``typewriter.''
J is passed to the next line.

The flowchart shown in FIG. 3 was designed to perform the above three processes. First, when a word cannot fit on one line, it is checked in step S1 whether there is a hyphen character in the character string in the first half of the word that could not fit on one line. This means that processing 1 is checked. Then, in step S, the result is checked, and if a hyphen is found, a line break is performed at the position of the hyphen in step S3. Step S
1, if there is no hyphen, in order to perform process 2 or 3, the words separated in step S4 are transferred to the search buffer BVFF without separation, and the control device 2 sends them to Sv/SC.
Send to 5. The SV/SC 5 searches the dictionary 6 based on the spelling of the word and reads out the hyphenation information. Then, it is sent to the comparison buffer CB of the control device 5. The information is received in step S5, and based on the information, it is determined in step S6 whether to perform process 2 or process 3. That is, it is determined whether there is a position where a hyphen can be inserted before the write margin. If there is a position where hyphenation is possible in the front section, processing 2 is performed in step S8. In other words, insert a hyphen where it is appropriate to insert a hyphen and start a new line. Conversely, if there is no position that can be hyphenated, the word wrap process of process 3 is performed in step S7. In other words, - A line break is performed at the rightmost blank space in a line.

After performing one of the three processes as described above and specifying the printing range, the process jumps to the printing routine of step S9, performs printing, and then continues the process of descending the next line. in this way,
When a word spans two lines, by performing one of the three processes above, hyphenation is more ideal and can be done automatically at the correct position in terms of writing.

FIG. 4 shows a concrete example. In Figure 4(a), rmothe
r-in-1awJ is “mothe/r-in-1
This shows an example of printing when the text is separated by aw J. Process 3 is performed because there is no hyphen or position where hyphenation is possible in the first half. In Figure 4(b), mother
This is an example of printing when the lines are separated as /-in-1awJ, but it is strange that the beginning of the line is a hyphen, and there is no hyphen or a position where hyphenation is possible in the first half, so Process 3 is performed. In Figure 4(c)(d)(e),
rmother-/in-1awJ, rmothe
r-i/n-n-1a, rmother-in/-1
awJ, but there is a hyphen in the first half, so process 3 is performed. In Figure 4 (f), (g), and (h), rmother-in-/1awJ, rmoth
er-in-1/awJ, mother-4n-
1a/wJ, and there is a hyphen in the first half, so process 3 is performed. In this case, there are two hyphens, but as in the case of hyphenable positions, when there are multiple hyphens, the rightmost one is used as a line break. In Figure 4(i), mother-4n-1
awJ does not need to be separated, so no special processing is required.

FIG. 5 shows an example in which a hyphen does not exist in a word.

r typewritingJ is the word “typewriting”.
・Hyphenation is possible with the two ・ shown in ``Writ-1ng''. In Figure 5 (a), ``type / wr

In Fig. 5(b), (c), and (d), rtypew

rtypewr/itingJ, rtypewri/
An example of printing when separated with lingJ is shown, but since the condition of step S6 is satisfied, process 2 is performed. Figure 5(e) shows an example of printing when the line is separated by "typewrite/ingJ", but there are two possible hyphenation positions, but for the same reason as in Figure 5(a), rtype

A printing example is shown in which the characters are separated as ``w r i t i n / g J'', and there are two positions where hyphenation is possible, and the two positions are separated on the right side. In FIG. 5(h), no special processing is performed because it is not separated from "typewriting J."

This time, we attempted to automate hyphenation during batch printing using a database with hyphenation information, but when printing sequentially or hyphenation in manual mode, we can check whether the hyphenation position specified by the user is correct. , you can make a determination by comparing it with the hyphenation information in the database.

〔effect〕

By automatically performing hyphenation using a storage device that has hyphenation information as explained above,
The user's operability when printing documents has been greatly improved, there are no errors in writing, and even users with little knowledge of calligraphy can easily create correct documents.

FIG. 3 is a flowchart of automatic hyphenation processing, and FIGS. 4 and 5 are diagrams showing examples of printing according to the present invention.
