Royo's pattern data origin P. S through the routine 161b to move to the position.
Jump to EWlO address 129. Therefore, after forming the embroidery stitch of the kana character 0yo, the needle 4 is stopped in the needle up position according to the routine 160.

After the needle 4 has stopped moving up, the routine 161b is used to form the next embroidery pattern 1.
The h command is read out, and the embroidery frame 19 is moved based on the command. Thereafter, the stitches of the embroidery pattern of the kana character 1yo are formed on the work cloth 9 in the same manner as in the formation of the embroidery pattern of the kana character 0yo described above.

Note that, as shown in FIG. 17, for each stitch block SArl, SAn+1, .
Embroidery frame 1 to the calculation result position of 1, SNn+1...
The position data for moving 9 is SEWDATA◆R
E.G. Since each stitch command is stored as each stitch command, the first pulse motor 8 for setting the amount of swing of the needle 4 when forming an embroidery pattern based on the stitch command is fixed at the origin position. The needle 4 is not swung, and only the embroidery frame 19 is moved in a zigzag pattern to the stitch forming position by the second and third pulse motors 14 and 15 (see FIG. 18).
An embroidery pattern seam is formed on the top.

After all the embroidery patterns have been formed, the program returns to SEWlO address 129, and from routine 130 to routine 162 for moving the embroidery frame 19 to the embroidery start position of the first character pattern, CYCLEEND.REG. It returns to the main address via a routine 163 that sets H at , and then continues to loop through the monitor loop 106.

Therefore, as described above, after the stitches of the embroidery pattern of Kana 1 and 1 alphabet programmed by the operator are formed, the embroidery frame 19 is moved to the embroidery start position of the first character pattern, so that the operator can start a new process. When the cloth 9 is set in the embroidery frame 19, stitches of the same embroidery pattern as described above can be formed again.

Note that the amount of movement of the embroidery frame 19 in the X and Y directions is so large that the movement of the embroidery frame 19 cannot be completed while the needle 4 is out of the work cloth 9 during the formation of each character embroidery described above. If so, the sewing machine main body 2 is controlled by a routine 160 which outputs a needle up stop signal to the sewing machine drive circuit 74 to stop the needle 4 in the needle up position, and a routine 165 which outputs a drive command signal to the sewing machine drive circuit 74 again. The drive can be temporarily stopped.

In addition, in the above-mentioned example of forming an embroidery pattern of 1 Japanese kana character, the character arrangement is set using the Arrange command (AX3O) of standard control data as shown in FIG. 22 as control data for setting the character arrangement. However, if the control data is changed to, for example, AXll, AY2O by the same key operation as when changing the pitch described above, the arrangement of the respective kana characters 0 and 20 shown in Figs. 23 and 24 will be obtained. It is possible to form an embroidery pattern on the work cloth 9 having
. . . The embroidery patterns of each character can be arranged so that the reference points (Pl, P2, . . . ) for each character pattern data shown in FIG. 21 are aligned.

Regarding the Size command, by appropriately specifying the length of each pattern in the horizontal direction (X-axis direction) between 01 and 99wt by key operation, the specified Size is executed by routine 34 in the flowchart of FIG. Each data of the size corresponding to the command is SEWDATAIREG. An embroidery pattern having a size based on the command is formed on the work cloth 9 by each routine after routine 134. In addition, in the above embroidery example, the size of each kana character for 1 alphabet is set to the same size by the Size command based on standard control data, but for example, we would like to enlarge or reduce only the 7 character character. In this case, after the above-mentioned data key input operation for 1 ro of kana characters, execute the Size command corresponding to the requested enlargement/reduction data in the same way as the command operation for each control data described above, and then input the data for 1 ro of kana characters. All you have to do is perform a key input operation, and then perform the same data key input operation as for the kana character 1yo for the kana character 1yo.

It goes without saying that the control data commands for each embroidery pattern can be changed with respect to other control data by key inputting each control data command as described above between each embroidery pattern data.

In addition, in the above example of embroidery pattern formation, explanation has been given for kana characters 1 alphabet, but in addition to each character symbol etc. (alphabetic character symbol, alphanumeric character, kana symbol, kana character) displayed in each data key group of the keyboard 28, Various pattern data corresponding to each embroidery pattern such as kanji and other special characters and patterns are available in R.
They are stored in the data bank 66b of the OM66, and by selecting one or more of them by operating the PA key 48, the above-mentioned kana character 1 alphabet is selected according to the flowchart shown in the PATN key routine in FIG. As in the case, the operator can form the selected embroidery pattern on the work cloth 9 by selectively operating each pattern data.

In addition, pattern data for hiragana characters, cursive letters, etc. of English characters are also stored in the data bank 66b, and selection keys 37, 38, 39 and SHF'TL key 4

Then, the program returns to the main address again via routine 150, routines 170 and 171, and is stopped after executing only the first stitch command for the above-mentioned kana character 0yo. In addition, various program data such as area setting, pitch specification, embroidery character setting, etc. by the operator's key operations in the above-mentioned embroidery pattern formation example, such as RRlO, PO5, and ABCs, are stored in the FILE of the RAM 65.

For example, when embroidering a combination pattern on a work cloth using only one large pattern of one alphabet, the operator can easily change the program to correspond to the desired combination pattern. That is, when the LOAD key 51 is pressed for the first time, the program returns from the LOAD key address shown in FIG. 28 to the main address 105 via the routine 173. Therefore, the program content of the combination pattern stored in the FILEREG is the KEYI.

During each key operation, the routine 125 calculates in advance the maximum amount of movement of the embroidery frame 19 in the X and Y directions when forming the embroidery pattern of the combination pattern set based on the key operations. If the calculated value exceeds the movable range set based on the area setting (RlO), the display section of the dot matrix display device 56 blinks,
Needless to say, the system is designed to notify the operator of an operational error.

(Completion of changing the pattern size of a part of the combination pattern) If the operator presses the embroidery start command switch 23, the program will follow the same path as described above, so the combination pattern 1, opening, It is possible to form a new combination of embroidery patterns in which only one of the pieces is a large size (Sl6) and seven pieces and two pieces are standard sizes (SO8). In addition to the one size change mentioned above, RPitChJ. ．． rWidtho, RDensity
Needless to say, it is possible to form a new embroidery pattern of a combination pattern by changing the desired pattern or the pitch between the desired patterns among the combination patterns, such as J or the like.

Next, in the middle of forming the embroidery pattern of kana characters 1 and 1 as described above, a thread breakage signal (BROKEN signal) from a thread breakage detection device (not shown) or an emergency stop signal (EMERGENC signal) based on the operator's operation of the emergency stop switch 24 is detected.
A case will be described in which the input of each drive signal to the sewing machine drive circuit 74 and the first, second, and third drive circuits 71, 72, and 73 is stopped by the Y signal) or the like. First, when the input of each drive signal is stopped based on the generation of the thread breakage signal shortly after the formation of the embroidery pattern of the above-mentioned kana characters 1 and 1 is started, when the operator presses the RTN key 32, the program starts from the monitor loop 106 to the 40th embroidery pattern. The RTN key routine in the figure jumps to the position where the needle 4 has come out of the work cloth 9 (

The routine 179 sends a drive signal to the first drive circuit 71 in order to move it to the origin position, and the monitor loop 106 is continued again through the main address.

Therefore, the embroidery frame 19 is moved to the sewing starting point P by the pulse motors 14 and 15. The adjustment mechanism 7 is moved to the origin position where the amount of swing of the needle 4 becomes zero. Thereupon, the operator performs thread threading work, removing the stitches already formed on the work cloth 9, or replacing the work cloth, and then presses the sewing start command switch 23 again to start the embroidery work from the beginning. Note that if the needle 4 is in the position where it has not come out of the fabric (needle down position) when the thread breakage signal is generated, the above-mentioned routine 17 is executed.
4 prevents the embroidery frame 19 from moving to the sewing start point, but it is also possible to move the embroidery frame 19 to the sewing start point after the needle 4 is automatically moved to the needle-up position. be. Next, when the input of each drive signal is stopped based on the generation of the thread breakage signal after the formation of the embroidery pattern of 1 yō of kana characters is completed and shortly after the formation of the embroidery pattern of 1 yō of kana characters is stopped, first press the SGLDATA key 34.

After pressing R to light up the light emitting diode 35a
゛...When the key 32 is pressed, the program jumps from the monitor loop 106 to the RTN key routine, routines 174, 175, 180, RTN address 181, routine 182, 183, 185, R゛30 address 186,
It returns to the main address through routines 187, 188, etc., and continues around the monitor loop 106 again.

Therefore, the position SS corresponding to the seam forming point SNn+2
The embroidery frame 19, which had been stopped at n+2, is moved to position SSn+1 corresponding to stitch forming point SNn+1 adjacent to stitch forming point SNn+2 based on the pressing operation of the RTN key 32. Note that if the embroidery frame 19 has not been moved to the position SSn+2 corresponding to the stitch forming point SNn+2,
The program runs from routine 180 to routines 190 and 19.
Since the embroidery frame 19 goes through the route passing through 1 and jumps to 186, R゛30, 186, the embroidery frame 19 is placed at the seam forming point SNn+ in the same way as described above.
1 to the position SSn+1. After that, if the RTN key 32 is pressed, the program follows the same path as described above, that is, the routines 174, 175, 180,
183, 184, 185, 187, 188 and then continues around the monitor loop 106 again. Therefore, if the operator
By appropriately pressing the N key 32, the embroidery frame 19 can be moved to the position SSn corresponding to the stitch formation point SNn where the stitch is actually formed. Then, after moving the embroidery frame 19 to the SS point mentioned above, SG? By pressing the TIT key 35 to turn off the light emitting diode 35a, and pressing the sewing start switch 23 again, sewing can be started again from the stitch formation point SNn of the kana character 1yo. Effects As detailed above, the present invention stores a large number of embroidery pattern data such as characters and symbols in a storage device in advance, and provides a pattern selection means that can arbitrarily select the embroidery pattern data stored in the storage device. Further, a setting means for setting the arrangement direction and spacing of each embroidery pattern data selected by the pattern selection means, and a scaling means for scaling each of the selected embroidery pattern data, the setting means and the scaling means The work cloth is moved based on each embroidery pattern data specified by the user, and embroidery patterns are automatically applied to the work cloth. Not only can it easily handle various embroidery patterns that differ in at least one of the arrangement direction, spacing, size, etc. of some of the characters, symbols, etc. of the embroidery patterns to be formed, but also the storage device can be sewn. Since it is only necessary to memorize the embroidery patterns such as letters and symbols that correspond to the embroidery pattern to be processed, the storage device can be made small, and the embroidery pattern can be beautifully and uniformly printed on the fabric without requiring the operator's skill. It has excellent effects such as being able to form beautiful embroidery patterns.
