Description

Detailed Description of the Invention [Industrial applications]

The present invention relates to a printing apparatus which automatically determines a syllable of a word continuing on the next line and automatically inserts a hyphen at a syllable division.

[Prior art]

Conventionally, in the electronic typewriter that mainly prints European text,
Printing is performed with line ends aligned to make the document beautiful and easy to read. As a method of automatically aligning the end of a line with the right margin, the character data input for one line is stored, and the end of the word closest to the right margin without exceeding the right margin is regarded as one line, and the line There is a method (justification) of printing by adjusting the space between words so that the characters fit within the light margin. However, this method has a problem that in the case of a word that exceeds the light margin and has a large number of characters in the light margin, the adjustment space becomes too large and the word interval unnaturally widens and the number of characters printed per line decreases. . In order to avoid this problem, it is necessary to divide a word on the right margin into two parts, insert a hyphen between them, and adjust the word interval so that the hyphen is aligned with the right margin. However, the hyphen must be inserted at the break of the syllable of the word, and it cannot be inserted freely. As a device that automatically detects the insertion position of this hyphen, it stores a reference pattern that serves as a criterion for segmenting a word, compares the pattern with the character configuration of the target word, determines the segment point, and It is known that a hyphen is inserted (Japanese Patent Laid-Open No. Sho 50).
-128927 publication). Also, even in the method of printing without aligning the line ends, when a word with a large number of characters is applied to the light margin, the operator manually sets the syllable breaks near the light margin in order to prevent the line ends from becoming extremely misaligned. It is common practice to insert a hyphen into.

[Problems to be Solved by the Invention]

However, the device that automatically inserts hyphens and prints with the line ends aligned uses a prefix, suffix, etc. as a reference pattern.The reference pattern and the character configuration of the target word are sequentially compared, and the first match Hyphens are inserted before or after the pattern, and then the spacing between words is adjusted so that the hyphens are located in the right margin. Therefore, when a prefix having a large number of constituent characters of the target word and a small number of characters is first found, the hyphen insertion position becomes far from the right margin. Therefore, there is a problem that the adjustment space becomes too large and the word spacing unnaturally widens. In addition, the method in which the operator manually inserts a hyphen at the break of the syllable in the vicinity of the light margin without aligning the line ends and prints it is cumbersome. There is a problem that the number of characters printed on a line is reduced.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to automatically insert a hyphen to improve operability and document creation speed. In addition to increasing the number of print characters per line,
This is to make the document beautiful and easy to read by making the word interval not smaller than a predetermined reference interval, and to determine the hyphen insertion position and perform line feed processing at high speed.

[Means for solving problems]

As shown in FIG. 1, the structure of the invention for solving the above-mentioned problems is such that, as shown in FIG. A dictionary memory, a detection means for detecting a word exceeding the right margin among the words input to the first memory, and a search for searching data in the dictionary memory corresponding to the word detected by the detection means. Means and the word data searched by the searching means, sequentially reading each syllable information of the word from the beginning, and adding a hyphen after the word part delimited by the syllable information does not exceed the light margin. When the syllable position is determined and a hyphen is added after the word part delimited by the first syllable information, if the right margin is exceeded, all of the word data is Determining means for determining the moving to the next line, the, the data up to the syllable positions determined if the maximum syllable position has been determined by the determining means,
The hyphen added immediately after the data, the line feed code automatically inserted after that, and the data after the syllable position are sequentially stored in the second memory, and all the word data is moved to the next line. If it is decided,
A line feed code that is automatically inserted before the word and a control unit that sequentially stores the word data in the second memory are provided.

[Action]

The input word data is stored in the first memory, and the detecting means detects a word that exceeds a preset light margin among the words. The syllable information of each word is stored in the dictionary memory, and the searching means searches the dictionary memory to find syllable information corresponding to the detected word. Next, the deciding means decides a syllable break located to the left of the light margin (not including the light margin) from the syllable information and closest to the syllable information, and a hyphen is added after the word portion delimited by the first syllable information. When the addition exceeds the right margin, it is decided to move all of the word data to the next line. After that, the word data exceeding the write margin is reconstructed by the control input means into the data in which the hyphen and the line feed code are inserted at the break of the syllable, and is stored in the second memory. If it is decided to move to, the line feed code automatically inserted before the word and the word data are stored in order in the second memory. Therefore, the hyphen is inserted at a position as close as possible to the write margin, and the number of characters printed in one line can be increased. Further, when the line ends are aligned and printed, the number of adjustment characters for positioning the inserted hyphen in the right margin is minimized, so that the word interval can be made as narrow as possible.

【Example】

Hereinafter, the present invention will be described based on specific examples. FIG. 2 is a block diagram showing the electrical configuration of the printing apparatus. Central processing unit (CP
U) 20 is connected to ROM 21, RAM 22, input interface 23, and input / output interfaces 24, 25, 26 via an address bus, a data bus, and a control bus, respectively. A program memory 210 in which a control program for inputting data from the keyboard 1 and performing a printing operation is stored in the ROM 21
A dictionary memory 212 is formed which stores the word spelling together with the word syllable information. Further, the RAM 22 is formed with an input buffer memory 220 for temporarily storing input data and a print memory 222 for storing a fixed amount of print data, and the RAM 22 is backed up by a battery. here,
The input buffer memory 220 is the first memory and the print memory 2
22 corresponds to the second memory. I / O interface 2
Drive units 80, 82, 84 are connected to 4, 25, 26, respectively, and each drive unit has an LF motor 8 for feeding paper.
1. A CR motor 83 for moving the carriage, a print mechanism drive source 86 for feeding a print ribbon, impacting a print hammer, rotating a print wheel, etc. are connected. Next, the operation of the apparatus of this embodiment will be described with reference to the flowchart of FIG. 3 showing the processing procedure of the CPU. First, in step S1 (hereinafter, simply referred to as S1; the same applies to other steps), the key matrix of the keyboard 1 is scanned to read the key states, and it is determined whether or not a new key has been input. If it is not a new key input, the keyboard reading process is repeated until a new key is input. When it is determined in S1 that a new key has been input, the input key code is sequentially stored in the input buffer memory 220 of the next S2. Next, in S3, it is determined whether or not the input code is a delimiter code of words such as spaces and periods. If it is not the delimiter code, the process proceeds to S1 and the next key code input process is performed. On the other hand, if the determination result in S3 is YES, that is, if the words are separated, the process proceeds to S4, and the word data stored in the dictionary memory 212 is compared with the word data stored in the input buffer memory 220. Spell checking is done. If it is determined that there is an error in the check result in S5, S6
A warning is issued by and the correction processing of the word that is input by mistake is performed. Next, in S7, it is determined whether the word delimiter code exceeds the write margin RM. If the determination result in S7 is NO, S8
Then, it is judged whether or not the division code is in the hot zone. In this embodiment, as shown in FIG. 4 (a), the hot zone HZ is set as an area for the left six characters of the write margin RM. If the partition code does not exist in the hot zone HZ, the input word data is registered in the print memory 222 in S9, and the process returns to S1 to input the next key code. On the other hand, if it is determined that the delimiter code is in the hot zone HZ, the input word is stored in the print memory in S10.
The data for one line registered in the print memory 222 is printed after the spacing of each word is adjusted so that the line ends are aligned with the write margin RM in the next S11. The printing result is as shown in FIG. After printing, a line feed operation is performed in S12, and the process returns to S1 to enter the key code of the next line. By the above processing, the key codes for one line are sequentially input, and when the delimiter code is input when the input position is within the hot zone HZ, the input one line is printed. On the other hand, in S7, the word delimiter code is the right margin RM.
If it is determined that the value exceeds the limit, the process proceeds to S13 and the dictionary memory 2
The corresponding word data is read from 12. The word data in the dictionary memory is stored in syllable units so that the division of syllables can be discriminated, for example, as shown in FIG.
Now, when "specification" is input and it is determined that this word exceeds the right margin, the dictionary memory 212 is referred to and the word is divided into syllables in S14. Next, the first syllable "spec" is read in S15, and the syllable is provisionally registered in the print memory 222 in S16. Next, as a result of placing the syllable in S17, the position RM-1 one character before the right margin RM
It is determined whether or not S1 if not exceeded
The process shifts to 8 and the temporary registration is made the main registration, the next syllable is read in S19, and the processing of the CPU 20 returns to S16. In this way, each syllable is sequentially main-registered in the print memory 222 until it exceeds the position RM-1. If it is determined that the syllable temporarily registered in the print memory 222 in S17 exceeds the position RM-1, the process proceeds to S20, and the temporarily registered syllable is temporarily erased from the print memory 222, and the syllable temporarily erased in S21. Is determined to be the first syllable and the determination result is YE
If S, the process proceeds to S23, and if the determination result is NO, a hyphen is registered in the print memory 222 in S22. This processing is performed because there is no space to insert a hyphen when the first syllable exceeds the position RM-1, so it is necessary to start a line break before the word beyond the right margin RM. is there. In this way, one line of print data is registered in the print memory 222, and the spacing between each word is adjusted so that the end of the registered data (including the hyphen if it has a hyphen) is aligned with the right margin RM in S23. Is adjusted and then printed, and the next S24
The line feed processing is performed with. Then, in S25, the syllable temporarily erased in S20 is registered from the beginning of the print memory 222, and S
At 26, all the remaining syllables are registered. Then CPU2
The process of 0 returns to S1, and the input process of the print data of the next line is executed. In the above process, for example, as shown in FIG. 4 (b), the fifth syllable "tion" of "specification" is located at the position RM-1.
If it exceeds, a hyphen is automatically inserted after the fourth syllable and "specifica-" is printed as shown in FIG. 4 (c). In this way, the word is divided into two by the syllable delimiter located closest to the write margin RM, which does not include the write margin RM. In the above-described embodiment, the function of the detection means, which is a constituent element of the invention, is mainly S7, and the function of the search means is mainly S13.
, The function of the determination means mainly S14 ~ S17, S20, S21,
The function of the control means is achieved mainly by a series of processing steps of the CPU 20 which executes S18 to S19 and S22 to S26. In addition, in the above-mentioned embodiment, the example in which the justification function is used at the same time is described, but the present invention is extremely excellent because the line end can be brought close to the write margin RM even when the justification function is not used. Is. Further, although an example in which the present invention is applied to a typewriter has been described in the above embodiments, the present invention can also be applied to a device such as a CRT display device or a liquid crystal display device which temporarily displays an input document.

【The invention's effect】

The present invention decomposes words that exceed the right margin into syllables, automatically inserts a hyphen at the break of the syllable at the position closest to the right margin that does not include the right margin, and detects the word part delimited by the first syllable information. If a hyphen is added later and all of the word data is moved to the next line when it exceeds the light margin, the number of characters printed per line can be maximized and the word interval can be set to a predetermined value. It does not become smaller than the reference interval. Therefore, when the line ends are aligned and printed, the word spacing can be minimized to make the document beautiful and easy to read. Further, the hyphen insertion and line break determination are performed each time the syllable information is sequentially read for each syllable, so that the determination result can be obtained quickly and the line feed processing can be sped up.
