A symbol representing Capricorn shown in is formed on the work cloth 19. When the execution of step S8 is completed, the control program shown in FIG. 6 ends, and the above-described operation is repeated every time the birthday is set by the setting means. For example, if your birthday is January 20th, the identification code is ROl2O3 and the storage address is R23 according to Figures 3 and 4.
The display information and specific pattern information taken out to the 4RAM 44 include content to display the constellation Aquarius and stitch data for sewing a symbol representing the constellation Aquarius.

In this way, according to this embodiment, when a numerical number representing a birthday is input, the name of the pattern corresponding to it is displayed on the display device 12, so if there is an error in the setting input, it can be corrected. You can know for sure. Therefore, the formation of erroneous patterns is largely eliminated. In addition, the symbol representing a constellation in the Western horoscope, which is not generally known, can be automatically embroidered by having the customer input the generally accurate information of birth date, so there is no need to worry about inaccurate memory of the customer. Compared to inputting the name or symbol of a constellation based on the name of the constellation, it is possible to accurately select and form the symbol representing the constellation, and it is also possible to search for the corresponding constellation using a comparison table showing the date of birth and the corresponding constellation. This eliminates all the troublesome work.

Although the embodiment of the present invention has been described above based on the drawings, the present invention can be applied to other embodiments as well.

For example, a figure representing a zodiac sign related to the birthday can be formed on the work cloth 19 by inputting the birthday.

Step S provided in the control program

This step S allows you to start sewing.
After 7 is removed and the birthday data input completion key 32 is operated, the symbol representing the constellation may be automatically formed.

Further, the CPU 48 and the RAM 44 in the above-described embodiment may be configured by a so-called microcomputer, and the ROM 46
It can also be constructed by a so-called floppy disk device.

As detailed above, according to the automatic sewing machine of the present invention, the pattern name corresponding to the input information is displayed on the pattern name display means in response to the setting input. You can check the name, and if there is an error in the setting input, you can definitely know it and re-enter it.

Therefore, it is possible to eliminate the work of removing a pattern erroneously formed on the work cloth and the deterioration in sewing quality caused by the marks formed after the removal. In addition, the customer's desired stitch pattern, which is symbolized in advance in relation to the birthday, which is generally accurate information, is automatically formed on the processed fabric, so that stitch pattern that is generally unknown. By inputting the type of seam pattern based on the customer's inaccurate memory and forming the seam pattern, the type of seam pattern to be formed can be accurately selected, and by using a comparison table. This eliminates the troublesome task of searching for the type of stitch pattern that corresponds to your birthday.
