And character string patterns (for example, “AEGLN”, “DEFHOQ”,. .
[0037]
The RAM 25 is provided with memories (memory such as flags, pointers, counters, registers, buffers, etc.) necessary for the various controls.
Next, a pattern selection display control routine executed by the control device C will be described with reference to the flowchart of FIG. In the figure, symbol Si (i = 10, 11, 12,...) Indicates each step.
When this control is started by turning on the power, an initial screen for selecting a pattern type (classification) is first displayed on the display 10 (S10). For example, as shown in the nest 7, selection keys 11a to 11d for selecting a character pattern according to a typeface, a selection key 11e for selecting a practical pattern, selection keys 11f to 11h for selecting a concrete pattern, and further mounted. A selection screen including a selection key 11i for selecting an embroidery pattern recorded on the ROM card 27 is displayed.
[0038]
Then, a menu selection process for selecting a desired embroidery pattern group type by pressing the touch key 11 corresponding to the type is executed (S11), and a number of embroidery patterns included in the selected pattern group are executed. Are displayed as a list in a matrix (S12). For example, when a pattern group related to “animals / vehicles” stored in the ROM card 27 is selected by operating the touch key 11i, a pattern group related to many animals or vehicles is displayed in a matrix as shown in FIG. Is done. Here, by operating “next page” or “previous page”, an embroidery pattern can be displayed over a plurality of pages.
[0039]
When a character pattern is selected by operating the selection keys 11a to 11d, a character pattern selection screen is displayed as shown in FIG.
Next, when a selection process for selecting one of the pattern groups is performed by operating the touch key 11, the selected embroidery pattern number (however, for a character pattern, the character pattern number) is displayed. The pattern is stored in the selected pattern number memory of the RAM 25 (S13), and the color-specific pattern portion relating to the embroidery pattern is displayed (S14). However, when operating the touch key 11 to instruct “return”, the process returns to S10 and the initial screen is displayed again.
For example, when an animal “elephant” is selected, as shown in FIG. 10, an embroidery pattern “elephant” and three color-specific pattern portions included in the “elephant” are displayed on the display 10.
[0040]
Next, when the “determine” key is operated in conjunction with the determination of the embroidery pattern to be sewn, an edit screen is displayed on the display 10, so that an edit process for changing the sewing position, size, etc. is executed. (S15). For example, as shown in FIG. 11, an embroidery area corresponding to the embroidery frame 34 is displayed on the display 10 as a rectangular frame E, and the selected embroidery pattern “elephant” is displayed inside the rectangular frame E. On the other hand, there are a plurality of movement function symbols (arrows) for moving the sewing position in eight directions, a rotation function for rotating the direction of the embroidery pattern by 90 °, a size changing function for changing the size of the sewing size, etc. The function name is displayed.
[0041]
Here, the editing process itself is a general process, and various known editing processes may be applied.
Next, after the work cloth W to be used for embroidery sewing is set in the embroidery frame 34, when the start / stop switch 12 is operated to execute embroidery sewing (S16: Yes), the sewing control is started to perform sewing. Is started and screen display during embroidery sewing is executed (S17). For example, as shown in FIG. 12, the display 10 displays the above-mentioned embroidery pattern “elephant”, a color-specific pattern portion, various accompanying information, and the remaining required time (remaining time) required for embroidery sewing, and the like. The function name necessary for sewing is displayed.
[0042]
When the embroidery sewing is completed (S18: Yes), the process returns to S10 and the initial initial screen display is executed.
Next, the sewing control shown in FIG. 6 is executed in response to an instruction to start the sewing control.
When this control is started, a sewing pattern number used for sewing is first read from the selected pattern number memory of the RAM 25 (S20). Next, when the pattern with the pattern number is an embroidery pattern (S21: Yes), it is searched whether the pattern number is an embroidery pattern number subject to copyright or not, and when the pattern number is a embroidery pattern subject to copyright (S22: Yes). The identification pattern sewing data is read, and based on the embroidery pattern sewing data of the embroidery pattern number, the identification pattern sewing data is stored in the embroidery in the RAM 25 so as to be located in the area corresponding to the embroidery area in the outline of the embroidery pattern. The data is developed and stored in the data memory (S23).
[0043]
Next, sewing data of a plurality of color-specific pattern portions included in the edited embroidery pattern is developed and stored in the embroidery data memory (S24), and embroidery sewing processing is executed (S25). That is, in this embroidery sewing process, the first and second stepping motors 32 and 33 of the embroidery device 30 are driven and controlled, and the motors 17, 19, and 41 are driven and controlled. First, the identification pattern sewing data in the embroidery data memory is controlled. Is sewn with the lower thread tension, and after returning to the normal thread tension and the first color-specific pattern portion is continuously embroidered, every time the embroidery thread is replaced, the remaining color-specific pattern portions are similarly embroidered. Is done.
[0044]
For example, as shown in FIG. 13A, when the embroidery pattern “elephant” 50 selected from the ROM card 27 is embroidery sewn, the embroidery pattern “elephant” 50 of the back side Wb of the work cloth W is selected. In the area corresponding to the inner embroidery area of the outer shape 50a, the identification pattern “123”, which is the manufacturing number of the embroidery sewing machine M, is first sewn with the lower thread tension, and the identification pattern “R413”, which is the manufacturing number of the ROM card 27. "Is sewn with the lower thread tension. Then, as shown in FIG. 13B, after the first color-specific pattern portion is continuously sewn with the normal thread tension, the remaining color-specific pattern portions are similarly embroidered each time the embroidery thread is replaced. Then, the embroidery pattern “elephant” 50 is colorfully formed on the surface side Wa of the work cloth W.
[0045]
By the way, when there are a plurality of sewing pattern numbers read from the selected pattern number memory and a character string pattern (S21: No), whether or not the character string pattern is a copyright object is searched for a plurality of character string pattern number combinations. When the character string pattern is subject to copyright (S26: Yes), S23 and subsequent steps are executed in the same manner, and before the embroidery sewing of the character string pattern, within the embroidery area corresponding to the inside of the embroidery area of the character string pattern, The identification pattern which is the production number of the embroidery sewing machine M and the identification pattern which is the production number of the ROM card 27 are respectively sewn with a lower thread tension.
[0046]
Next, operations and effects of the electronically controlled embroidery sewing machine 1 will be described including an embroidery pattern sewing method.
The ROM 24 of the control device C and the ROM 28 of the ROM card 27 store pattern display data and sewing data relating to each of a plurality of embroidery patterns, and are composed of the needle thread feed amount correction data, the embroidery sewing machine M and the manufacturing number of the ROM card 27. Identification pattern sewing data, copyright target embroidery pattern number, copyright target character string pattern, etc. are stored, and the embroidery pattern or character string pattern subject to copyright selected from among a plurality of embroidery patterns is stored. At the time of sewing, the identification pattern consisting of the production number of the embroidery sewing machine M and the ROM card 27 is always automatically sewn on the back side Wb of the work cloth W by the lower thread tension. Sometimes, the embroidery sewing machine M and the ROM card 27 can be easily identified from the identification pattern appearing on the back surface Wb of the work cloth W without solving the embroidery pattern. .
[0047]
The identification pattern is sewn together with the embroidery pattern without protruding from the embroidery area of the embroidery pattern, so the identification pattern cannot be separated from the embroidery pattern, and the identification pattern and the embroidery pattern are always integrated. From the identification pattern, unauthorized use by a person other than the owner of the embroidery sewing machine M can be easily determined. Furthermore, since the identification pattern is sewn in an area corresponding to the embroidery area in the outer shape of the embroidery pattern on the back side Wb of the work cloth W to be embroidered, the work cloth W can be obtained without impairing the appearance of the embroidery pattern. The identification pattern can be reliably held on the back side Wb of the image, and the identification pattern can be easily read from the back of the work cloth W without unraveling the embroidery stitches, and the embroidery sewing machine M and the ROM card 27 can be reliably identified. be able to.
[0048]
By the way, the manufacturing data of the embroidery sewing machine M and the ROM card 27 is stored in the ROM 24 as normal image sewing data that is not a mirror image. In the embroidery sewing processing in the sewing control, as shown in FIG. The identification patterns “123” and “R412” are sewn to the embroidery area in the outer shape 50a of the surface side Wa of the work cloth W with a normal thread tension, and then a plurality of pattern parts by color are successively sewn. You may do it. In this case, since the identification pattern is sewn below the embroidery stitch of the embroidery pattern, the identification pattern can be securely held without impairing the appearance of the embroidery pattern, and the identification pattern can be easily released by releasing the embroidery stitch. Can be read.
[0049]
Here, in the above-described embodiment, the ROM card 27 composed of a flash memory or the like is used. However, as described in Japanese Patent Application No. 8-133263 by the present applicant, an embroidery pattern is provided on the CD-ROM. May be stored. In this case, the embroidery pattern data is supplied from the data reader to the sewing machine via a card-type adapter that can be installed in the card slot 2a of the sewing machine. This card type adapter has the same shape as the ROM card 27, and the data reader converts the data read from the CD-ROM, which is an optical storage medium, into the data format of the flash memory, which is a semiconductor storage medium. The converted data can be supplied. Therefore, the sewing machine is the same as when the ROM card 27 is installed. Further, if such a conversion function of the data reader is provided in the sewing machine body, the data reader may be a general-purpose CD-ROM device. In particular, when displaying detailed information in a detailed image (for example, an image like a photograph) or color, a large amount of storage capacity is required, so it is better to use a CD-ROM.
[0050]
In the above-described embodiment, the identification pattern sewing data is sewn prior to the sewing of the embroidery pattern. However, sewing may be performed at the same time when any one of the plurality of color-specific pattern portions is sewn. In addition, the case where the pattern data of each embroidery pattern includes sewing data and pattern display data has been described as an example. However, when the pattern data is composed only of sewing data, the sewing data is processed and the pattern display data is processed. Can also be created. The display 10 may be a CRT display. Further, instead of the ROM card 27, pattern data of a plurality of patterns may be stored on a magnetic disk, and the magnetic disk may be detachably mounted on the FDD of the control device C. It is also possible to apply a CD-ROM or a magnetic optical disk. The pattern selection display control and the sewing control according to the embodiment are merely examples, and can be implemented with various modifications without departing from the technical idea of the present invention.
