Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application) The present invention relates to a computer sewing machine capable of memorizing Arabic characters.

(Prior Art) Recently, it has become possible to automatically form various characters on seams using home computer sewing machines, and these characters have been put to practical use, such as marking names on clothing and the like. As for the types of characters, Roman letters and arithmetic numerals are generally used, and in Japan, sewing machines that can sew hiragana, kanji, etc. are commercially available.

(Problem to be Solved) Arabic letters are used and cherished not only by Arabic speaking peoples but also in quite wide areas of the world. Therefore, in these regions, there is a demand for a sewing machine that can form Arabic characters using stitches.

However, the Arabic alphabet differs from the Roman alphabet not only in its characters, but also in that both sentences and words are read and written from right to left, and the shapes of the letters for the same phonetic sound vary depending on the spelling position of the word. Therefore, for sewing machines for these regions, even if the conventional sewing machine that was able to sew Roman alphabets was designed to take measures such as replacing the memorized characters with Arabic characters, it would still be difficult to use. In addition, the number of operation units for selecting and specifying each character corresponding to changes in character shape becomes excessively large, which is undesirable.

(Solution Means) In the present invention, due to the stitching of Arabic characters, the shape of the Arabic characters changes according to the spelling positional relationship for the same phonetic sound, but the selection of characters and the display of the selected characters are , a representative glyph shape is used for the same phonetic sound, and the computer calculates and specifies changes in glyph shape according to the memorization order of each character by selection and the word break specification, or changes are made through operations. By specifying this, characters with glyph shapes based on Arabic conventions are sewn out. Also, in order to cope with the convention of reading and writing from right to left, and to share the sewing machine with the convention of reading and writing from left to right in the Roman alphabet, the sewing of each letter was changed for Arabic characters. Reverse the order in which each character is memorized by selecting it,
The base line of the character coordinate data is set and stored as a right base line and a left base line, respectively, depending on the above-mentioned read/write direction agreement.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. While the Roman alphabet has 26 letters, the Arabic alphabet has 29 basic forms (independent forms), with each pronunciation corresponding to the phonetic sound (romanization in the figure), as shown in part in Figure 8. Consists of letters. Then, depending on the context of the spelling, each independent form is used as is, or instead of the independent form, an initial form, a middle form, a tail form, etc. are used to connect multiple letters sequentially from right to left. write. 29 more
In addition to letters, as shown in Figure 8, there are auxiliary short vowel symbols such as the fuatha symbol, kasra symbol, and dhamma symbol, long vowel symbols such as the alif of letters, and vowelless symbols such as the sukukun symbol. Note that other promises will be omitted to simplify the explanation. In each symbol in the figure, "-" indicates the positional relationship of each of the 29 characters. By placing each symbol above or below each letter, each symbol promises to be pronounced by adding the corresponding short vowel to the consonant of each letter. FIG. 1 is a block diagram of a control circuit of a computer sewing machine, and an electronic storage device 1 stores stitch coordinate data such as characters and symbols of each type in each memory in each storage location indicated by numerals 2 to 6 in the figure. I remember each of them.
Note that the other pattern memory 7 includes English characters and stores stitch coordinate data of each sewing pattern. The pattern selection key 8 is used to select each character or pattern including Arabic characters, and for Arabic characters, the independent character is selected as a representative for each Roman alphabet transcription shown in FIG. The character form specification key 9 is operated in conjunction with the pattern selection key 8 to specify or suggest a change in the shape of the Arabic character. It consists of a delimiter specification key that specifies the delimiter for each spelling. The space key 10 specifies that a space be provided between each character in the series. The storage key 11 is used to specify that each of these selection and designation operations be stored in a storage buffer 12, which will be described later. Arithmetic means 13
In response to the specification of each key 8 to 11, as shown in Fig. 2, the code for making a pair with the character code of each selected character and performing each shape and each auxiliary designation of the character is written. Set by a 10-bit binary number. The correspondence of these codes is shown in FIG. The memory buffer 12 stores the second memory buffer 12 according to the pattern selection.
This is for sequentially storing the codes shown in the figure in association with each character, or for storing each calculation process of the calculation means 13 at a timely manner. The display unit 14 electrically displays Arabic characters in independent form. The reading means 15 reads out the code shown in FIG. 2 at each start or end of each stitch of each Arabic character, and sequentially associates the code with each of the memories 2 to 7 of the electronic storage device 1 according to the code. When reading the data, it cooperates with the calculation means 13 as necessary. The sewing means 16 forms each stitch of the character (pattern) based on the stitch control signals from the memories 2-7.

The operation of the above configuration will be explained with reference to the flowcharts of FIGS. 3 to 7. In FIG. 3, when each of the keys 8 to 10 is operated in conjunction with the operation of the memory key 11, a character memory program is started. The operations of these keys 8 to 11 are written into the memory buffer 12. Each character is selected in reading order from right to left. Regarding the Arabic characters, the selected characters are electronically displayed in independent form on the display section 14. Below, when an Arabic character is selected, for example, if the space key 10 is operated, a space designation code is calculated and written to a predetermined memory address (NO) of the memory buffer 12, and then The program advances the address by 1 and returns to the beginning (RET). Next, when one of the Arabic characters is selected using the pattern selection key 8 and the character form specification key 9 is not operated, the independent form character specification code is calculated and this is written in the same way, instead of the combined form described later. and increments the address by 1.
Next, when the selection of an Arabic character using the pattern selection key 8 and each specification using the character form specification key 9 are used together, there is a case where a combination of a character and a symbol is specified, or when a combination of characters is formed by joining together. There is a combination form, such as when the character is in a form other than the independent form. For example, if the character number 2 in FIG. 8 is selected using the pattern selection key 8, and the initial letter form FATHA is commanded using the character form designation key 9, then with reference to FIG. The code is
0010100010, which is stored in the same manner and the address is advanced. The phonetic copy based on this code designation is Ba, and the shape of the Arabic letter sewn is character number 2.
It has the form of an acronym with "'" added above it. Thereafter, each code is written into the memory buffer 12 in the same manner. When an alphabetic character is selected by the pattern selection key 8, the upper 3 bits are 101 with reference to FIG.
Each English code consisting of is calculated and written in the same way.

Next, when the sewing machine is rotated to sew out each character stored in the program shown in FIG. 3, the character sew-out program shown in FIG. 4 is started at the beginning. Regarding Arabic characters, the code of the last written address for a series of Arabic characters is specified in the program shown in FIG. 3, and the character information code of the address is read from the memory buffer 12. If this is an alif specification code,
In the Arabic spelling order, there is a convention that an alif letter is joined with the previous letter but not with the later letter, so after sewing half a space, the electronic storage device 1 The stitch coordinate data of the alif character is read out, and a stitch is formed by the stitching means. When the sewing of the alif characters is completed, the memory buffer 12
The address of is returned by 1. That is, in the program shown in Figure 3, Arabic characters are read and written from right to left, while in Figure 4 they are read in the opposite direction and are sewn out sequentially from left to right, similar to English text. There is. In the electronic storage device 1 used for this program, the stitch coordinate data of each Arabic character is such that the bottom of the character space allocated to each character when the Arabic character is placed in the normal position is the sewing machine. Stitches are similarly formed for characters other than alif, which are configured to correspond to the left base line in the needle width of , without discard stitches. If it is a space specification code, after sewing one character's space,
Move on to reading the next code. When all the memorization has been completed, the program returns to the beginning and waits for a new designation. When an Arabic character is not specified, that is, when an English character is specified, the character information code of the address written first for a series of English characters at the beginning of rotation of the sewing machine is read out. In this case, the address of the memory buffer 12 is incremented by 1 each time a character is formed. That is, for English characters, the order of writing and reading is the same. In the electronic storage device 1, the bottom of the character space also corresponds to the left baseline for each alphabetic character.

FIG. 5 shows a character sewing program showing another embodiment in place of the one shown in FIG. 4. In the electronic storage device 1 used for this program,
In the stitch coordinate data for each Arabic character, the bottom of the character space corresponds to the right base line of the sewing machine, and similarly for English characters, it corresponds to the left base line. In this case, the program shown in FIG. 3 is used for writing, and both Arabic and English characters are read out in the order in which they were written.

FIG. 6 shows a character storage program showing another embodiment in place of FIG. 3, and its sewing is executed by the character sewing program shown in FIG. 7, which will be described later. The character form designation keys 9 used in FIG. 6 do not designate each character shape individually, but consist of delimiter designation keys that are operated for each mutual delimitation of each spelling of Arabic characters. A series of characters and their delimiter positions are stored in a memory buffer 12. Each character shape is determined in the program of FIG. In FIG. 6, when a delimiter is not specified for an Arabic character, the Arabic character code including the upper three bits of FIG. 2 is calculated according to the program in FIG.
The address is incremented by 1, and in the same way, each code is sequentially written every time an Arabic character is specified. When a delimiter is specified, a delimiter designation code is written.

Next, the sewing is performed according to the sewing program shown in FIG. The character information code is read out, and if there is a delimiter designation code before or after the character, this means that the character is used alone, so an independent character is selected and sewn out. In the diagram, reset is
This is used by the program to specify the beginning of a spelling when reading a new character after it has been memorized, or when repeating after reading all of the characters. In the same way, determine whether a delimiter is specified and its context,
In accordance with the Arabic conventions, initials, middle letters, and suffixes are selected and sewn in sequence.

In FIGS. 6 and 7, a delimiter designation key is used as the character form designation key 9, and the designation code is determined, but these functions can be applied to the space key 10 instead of the delimiter designation key. It is also possible to have someone act on your behalf.

(Effects) As described above, according to the present invention, it is possible to select a character from a large number of characters and their promise of change with a relatively small number of operations, resulting in good operability. The space for the section can also be reduced.
