Further, it is assumed that the pattern “A” of the embroidery pattern “ABC” is sewn using the thread 28 of the second thread type information “800” whose thread color is “Pink”. Further, it is assumed that the pattern “B” is sewn using the thread 28 of the second thread type information “339” whose thread color is “BLUE”. Further, it is assumed that the pattern “C” is sewn using the thread 28 of the second thread type information “900” whose thread color is “BLACK”.

  An example of an image displayed on the liquid crystal display 15 will be described with reference to FIG. FIG. 10 shows an image displayed in the process of step S50 (see FIG. 16) when the first embroidery information is determined as the embroidery information to be sewn in the process of step S49 (see FIG. 16, described later). . As shown in FIG. 10, an embroidery pattern display area 151 is displayed on the upper part of the liquid crystal display 15. In the embroidery pattern display area 151, an embroidery pattern “ABC” based on the first embroidery information is displayed. When the sewing is executed, an embroidery pattern “ABC” is sewn on the work cloth 100 (see S57 in FIG. 16, described later).

  Of the embroidery pattern “ABC”, the thread color of the pattern “A” is “Pink”, the thread color of the pattern “B” is “BLUE”, and the thread color of the pattern “C” is “BLACK”. Therefore, the embroidery pattern display area 151 is displayed in a color corresponding to each.

  Below the embroidery pattern display area 151, a thread color display area 152 for displaying the thread color of the thread 28 used for the embroidery pattern “ABC” is provided. In the thread color display area 152, a thread spool display 153 representing the outer shape of the thread spool 29 is displayed. The thread spool display 153 is displayed in a color corresponding to the thread color to be used. On the right side of the thread spool display 153, a thread color display 154 displaying the name of the thread color is displayed. In this embodiment, since the thread colors “Pink”, “BLUE”, and “BLACK” are used, “PINK”, “BLUE”, and “BLACK” are displayed on the thread color display 154, and the color of the thread spool display 153 is “ Displayed in the colors “PINK”, “BLUE”, and “BLACK”. The user can confirm the embroidery pattern to be sewn by confirming the embroidery pattern display area 151. Also, by confirming the thread color display area 152, the thread color used for sewing can be confirmed.

  With reference to FIG.11 and FIG.12, the process which memorize | stores 1st thread | yarn type information in the 1st thread | yarn type information storage area 3112 of the alerting | reporting apparatus 30 is demonstrated. First, the first setting process by the CPU 61 of the sewing machine 1 will be described with reference to FIG. In the first setting process, after the user installs the yarn spool 29 and the notification device 30 on the spool pin 19, an instruction to perform processing for storing the first yarn type information in the notification device 30 is input by a panel operation or the like. Be started by.

  As shown in FIG. 11, first, a screen for selecting a thread type is displayed on the liquid crystal display 15 (S11). In step S11, the thread type data table 95 (see FIG. 8) is referred to, and a list of thread type information is displayed. The user refers to the product number described in the thread spool 29 installed on the thread stand 19 and selects the corresponding thread type information from the list of thread type information by operating the panel.

  Next, it is determined whether thread type information has been selected by the user (S12). If the thread type information is not selected (S12: NO), the process returns to step S12. When the thread type information is selected (S12: YES), the selected thread type information is transmitted to the notification device 30 via the reader / writer 81 (S13). The transmitted thread type information is received in step S21 (see FIG. 12) of the notification device 30, and stored in step S22 (see FIG. 12) as first thread type information. That is, the first thread type information of the notification device 30 can be rewritten by the process of step S13. Next, the first setting process is terminated.

  Next, the second setting process by the control unit 310 of the notification device 30 will be described with reference to FIG. The second setting process is a process for storing the thread type information transmitted from the sewing machine 1 as the first thread type information.

  As shown in FIG. 12, first, it is determined whether or not the yarn type information transmitted in step S13 of the sewing machine 1 has been received (S21). If the thread type information has not been received (S21: NO), the process returns to step S21. When the thread type information is received (S21: YES), the received thread type information is stored in the first thread type information storage area 3112 as the first thread type information (S22). Thereby, the yarn type information of the yarn 28 wound around the yarn spool 29 to which the notification device 30 is attached is set in the notification device 30.

  Next, a case where the thread spool group 31 shown in FIG. 13 is placed on a work table (not shown) on which the sewing machine 1 is placed will be described as a specific example. In this case, the yarn spool group 31 includes six yarn spools 291 to 296 to which the notification device 30 is attached. On the work table, thread spools 291, 294, 295, 296 are placed. A thread spool 292 is placed on the thread spool 291. A yarn piece 293 is placed on the yarn piece 294 and the yarn piece 295.

  Yarn pieces 291 to 296 are yarn pieces 29 around which yarns 28 of different yarn types are wound. In the notification device 30 attached to each of the yarn spools 291 to 296, the first yarn type information is stored by the process of step S22 (see FIG. 12). The first yarn type information stored in the notification device 30 attached to the thread spool 291 is “405”. As shown in the thread type data table 95 (see FIG. 8), the thread 28 of the thread type information “405”, the manufacturer “B company”, the thread color “SALMON-PINK”, and the count “50” 291 indicates that it is wound. Similarly, the first yarn type information “507” is stored in the notification device 30 attached to the yarn spool 292, and the first yarn type information “800” is stored in the notification device 30 attached to the yarn spool 293. Is stored. The notification device 30 attached to the yarn spool 294 stores the yarn type information “900”, and the notification device 30 attached to the yarn spool 295 stores the yarn type information “001”. The notification device 30 attached to the thread spool 296 stores thread type information “339”.

  With reference to FIG. 14, the alerting | reporting process by the control part 310 of the alerting | reporting apparatus 30 is demonstrated. The notification process is a process of notifying the user of the position of the thread spool 29 or notifying the sewing machine 1 that the second thread type information and the first thread type information are the same.

  As shown in FIG. 14, first, the second thread type information transmitted in step S44 (see FIG. 16), step S65 (see FIG. 18), and step S81 (see FIG. 21) executed by the sewing machine 1 is received. It is determined whether or not it has been done (S31). If the second thread type information has not been received (S31: NO), it is determined whether or not the thread type transmission command information transmitted in step S83 (see FIG. 21) has been received (S32). The thread type transmission command information is information for instructing the sewing machine 1 to transmit the first thread type information to the notification device 30. If the yarn type transmission command information has not been received (S32: NO), the process returns to step S31.

  When the thread type transmission command information is received (S32: YES), the first thread type information stored in the first thread type information storage area 3112 is transmitted to the sewing machine 1 (S38). The transmitted first thread type information is received in step S84 (see FIG. 21) executed by the sewing machine 1. After step S38 is executed, the process returns to step S31. The details of step S44, step S65, step S81, step S83, step S84, and step S88 described above will be described later.

  When the second thread type information is received (S31: YES), the second thread type information received in step S31 matches the first thread type information stored in the first thread type information storage area 3112. Is checked (S33). In other words, it is determined whether or not the type of the yarn 28 wound around the yarn spool 29 to which the notification device 30 is attached matches the second yarn type information. Next, according to the result of step S33, it is determined whether or not the second thread type information received in step S31 matches the first thread type information stored in the first thread type information storage area 3112. (S34). If the second thread type information does not match the first thread type information (S34: NO), the process returns to step S31. When the second thread type information and the first thread type information match (S34: YES), it is determined whether or not the notification command information is received together with the second thread type information received in step S31 ( S35). The notification command information is information for instructing the notification device 30 to notify the user of the position of the yarn spool 29. The notification command information is transmitted together with the second thread type information in step S81 (see FIG. 21) executed by the sewing machine 1.

  When the notification command information is received (S35: YES), the light emitting unit 303 emits light for a predetermined time (S36). For example, when the second thread type information received in step S31 is “405”, the light emitting unit 303 of the notification device 30 whose first thread type information is “405” emits light. As a result, as shown in FIG. 15, the light emitting unit 303 of the notification device 30 attached to the yarn spool 291 emits light (S36), and the position of the yarn spool 291 is notified to the user. In this case, in the notification device 30 attached to the thread spools 292 to 296, since the second thread type information and the first thread type information do not match (S34: NO), step S36 is not executed, and the light emitting unit 303 does not emit light.

  As shown in FIG. 15, since the light emitting unit 303 is provided on the outer peripheral surface of the notification device 30, the light emitting unit 303 is visible from the outside even when the yarn piece 292 is placed on the yarn piece 291. Is possible. For this reason, the user can confirm the position of the thread spool 291 with certainty. After step S36 is executed, the process returns to step S31.

  When the notification command information has not been received (S35: NO), coincidence information that is information indicating that the second yarn type information and the first yarn type information coincide with each other is transmitted to the sewing machine 1 (S37). ). This notifies the sewing machine 1 that there is a thread type (thread piece) necessary for sewing. The coincidence information transmitted in step S37 includes the first yarn type information stored in the first yarn type information storage area 3112. After step S37 is executed, the process returns to step S31.

  With reference to FIG. 16, the main process by CPU61 of the sewing machine 1 is demonstrated. The main process starts when the user inputs an instruction to display a screen for selecting an embroidery pattern to be embroidered.

  As shown in FIG. 16, first, a list of embroidery pattern images based on the sewing type information stored in the sewing type information data table 96 (see FIG. 9) is displayed on the liquid crystal display 15 (S41). The user temporarily selects the sewing type information by selecting a desired embroidery pattern from a plurality of embroidery pattern images displayed on the liquid crystal display 15 by a panel operation. Next, it is determined whether or not the sewing type information has been temporarily selected (S42). When the sewing type information is temporarily selected (S42: YES), the selected sewing type information is referred to, and a sewing thread type data table 97 that is a list of thread types for sewing the embroidery pattern is created (S43). ).

  For example, when the first embroidery information (see FIG. 9) is selected, a sewing thread type data table 97 is created as shown in FIG. As shown in FIG. 17, the sewing order and second thread type information associated with the embroidery type information “first embroidery information” in FIG.

  After step S43 is executed, the second thread type information is transmitted to all the notification devices 30 in the communicable range via the antenna 27 (S44). For example, the second thread type information “800”, “339”, and “900” stored in the sewing thread type data table 97 (see FIG. 17) shown in FIG. 17 is transmitted (S44). The transmitted second thread type information is received in step S31 (see FIG. 14) executed by the notification device 30.

  Next, the coincidence information transmitted in step S37 (see FIG. 14) executed by the notification device is received (S45). Next, it is determined whether or not a predetermined time has passed (S46). The predetermined time is, for example, 3 seconds. If the predetermined time has not elapsed (S46: NO), the process returns to step S45. By the processing in steps S45 and S46, a plurality of pieces of coincidence information transmitted from the notification device 30 that coincides with the second yarn type information is received.

  If the predetermined time has elapsed (S46: YES), it is determined whether or not coincidence information corresponding to all the thread types whose second thread type information is stored in the sewing thread type data table 97 has been received (S47). . When matching information corresponding to all thread types is received, all thread types (thread pieces) for sewing the embroidery pattern temporarily selected in step S42 are close to the sewing machine 1 (communication range). Is present. On the other hand, the case where there is a thread type for which coincidence information is not received indicates that there is no thread type (thread piece) near the sewing machine 1 among the thread types for sewing the embroidery pattern. In other words, there is an insufficient thread type (yarn piece). The coincidence information received in step S45 includes the first yarn type information stored in the first yarn type information storage area 3112 of the notification device 30 that has transmitted the coincidence information. For this reason, the CPU 61 of the sewing machine 1 can determine which yarn type match information is received. If coincidence information for all yarn types has been received (S47: YES), the process proceeds to step S49 (described later).

  If there is a thread type for which no match information has been received (S47: NO), a message indicating that there is no thread type (thread piece) near the sewing machine 1 is displayed on the liquid crystal display 15 and notified to the user. (S48). The message displayed on the liquid crystal display 15 in step S48 is, for example, “There are missing thread pieces”.

  Next, it is determined whether or not embroidery type information to be sewn has been determined by the user's panel operation (S49). That is, it is determined whether or not the embroidery type information provisionally selected in step S42 is acceptable. If the embroidery type information has not been determined (S49: NO), the process returns to step S42. If the embroidery type information is not temporarily selected in step S42 (S42: NO), the process proceeds to step S49.

  When the embroidery type information is determined (S49: YES), an embroidery pattern image based on the embroidery type information is displayed on the liquid crystal display 15 (S50). For example, when the first embroidery information is determined (S49: YES), the embroidery pattern “ABC” is displayed in the embroidery pattern display area 151 as shown in FIG. In addition, a thread spool display 153 and a thread color display 154 are displayed in the thread color display area 152.

  Next, for the embroidery type information determined in step S49, it is determined whether or not all thread type matching information has been received in step S45 (S51). If received (S51: YES), that is, if all the thread types (thread pieces) necessary for sewing exist, the process proceeds to step S53 (described later). If it has not been received (S51: NO), that is, if the thread type (thread piece) necessary for sewing is insufficient, the approximate color replacement process is executed (S52).

  The approximate color replacement process will be described with reference to FIG. The approximate color replacement process is a process of specifying the thread type that approximates the thread color of the missing thread type and updating the sewing thread type data table 97.

  As shown in FIG. 18, first, an unreceived yarn type data table 98, which is a data table of a list of yarn types for which coincidence information has not been received in step S45, is created (S61). For example, in FIG. 17, when there is no yarn 28 with the second yarn type information “800”, an unreceived yarn type data table 98 in which the second yarn type information “800” is stored is created as shown in FIG. The

  Next, one of the second yarn type information stored in the unreceived yarn type data table 98 is selected (S62). Next, the variable P is set to 1 (S63). The variable P is stored in the RAM 63. Next, a thread color approximate to the thread color indicated by the second thread type information selected in step S62 is calculated, and second thread type information corresponding to the calculated thread color is specified (S64).

Step S64 will be described in detail. As described above, in the thread type data table 95 (see FIG. 8), the thread color is indicated by the name of the color, but actually RGB values are stored. By using RGB values, the thread color approximation D can be calculated. Here, the RGB value of the thread color indicated by the second thread type information selected in step S62 is (R1, G1, B1), and the RGB value of the thread type for which the degree of approximation is obtained is (R2, G2, B2). . This degree of approximation D is calculated by, for example, the following calculation formula.
D = (R2-R1) ² + (G2-G1) ² + (B2-B1) ²

  Here, as the calculated degree of approximation D is smaller, both colors are closer and the degree of approximation is higher. In step S64, for all the thread types in the thread type data table 95, the degree of approximation between the thread color and the thread color indicated by the second thread type information selected in step S62 is calculated. Then, the thread type information corresponding to the thread color having the smallest degree of approximation D is specified as the second thread type information of the approximate color.

  For example, when the second thread type information “800” shown in FIG. 19 (that is, the second thread type information of the thread 28 of the thread color “PINK”) is selected in step S62, the thread type data table 95 (FIG. Among the yarn type information stored in (see Fig. 8), the one having the closest approximation D to "Pink" is "SALMON-PINK". For this reason, the thread type information “405” of “SALMON-PINK” is specified as the second thread type information (S64).

  After step S64 is executed, the second thread type information specified in step S64 is transmitted to the notification device 30 (S65). The second thread type information transmitted in step S65 is received in step S31 (see FIG. 14) executed by the notification device 30. Next, it is determined whether or not the coincidence information transmitted in step S37 executed by the notification device 30 has been received (S66). Next, it is determined whether or not a predetermined time (for example, 3 seconds) has elapsed (S67). If the predetermined time has not elapsed (S67: NO), the process returns to step S66.

  If the predetermined time has elapsed (S67: YES), it is determined whether or not the coincidence information is received in step S66 (S68). In other words, it is determined whether or not there is a thread type indicated by the second thread type information transmitted in step S65. When the coincidence information is received (S68: YES), in the sewing thread type data table 97, the second thread type information of the thread type selected in step S62 is updated to the second thread type information specified in step S64. (S69). For example, the sewing thread type data table 97 shown in FIG. 17 is updated as shown in FIG. In FIG. 20, the second thread type information “800” (see FIG. 17) for the thread color “Pink” is updated to the second thread type information “405” for the thread color “SALMON-PINK”.

  Next, the second yarn type information selected in step S62 is deleted from the unreceived yarn type data table 98 (S70). Thereby, for example, the second yarn type information “800” stored in the unreceived yarn type data table 98 shown in FIG. 19 is deleted. Next, it is determined whether there is second thread type information stored in the unreceived thread type data table 98 (S77). If there is second thread type information stored in the unreceived thread type data table 98 (S77: YES), the process returns to step S62, and new second thread type information is selected (S62).

  In step S68, when the coincidence information is not received (S68: NO), it is determined whether or not the variable P is equal to the predetermined number (S71). The predetermined number is “2”, for example. If the variable P is not the same as the predetermined number (S71: NO), the variable P is incremented and incremented by 1 (S72). Next, the process returns to step S64. In this case, in step S64, the thread color approximate to the thread color indicated by the second thread type information specified in step S64 immediately before is calculated, and the second thread type information corresponding to the calculated thread color is specified. . That is, steps S64 to S68 are repeated until the variable P is equal to the predetermined number (S71: YES), or until matching information is received (S68: YES), and the second selected in step S62. Second thread type information is identified in order from the color closest to the thread color indicated by the thread type information (S64), and the identified second thread type information is transmitted to the notification device 30 (S65). In other words, the thread 28 having a thread color approximate to the thread color indicated by the second thread type information selected in step S62 is searched.

  When the variable P is the same as the predetermined number (S71: YES), a message indicating that the thread type (thread piece) of the approximate color is not present is displayed on the liquid crystal display 15 (S73) and notified to the user. The The message displayed in step S73 is, for example, “There is no approximate color. Do you want to continue sewing?”. In step S73, for example, a button for accepting an instruction to continue sewing by panel operation and a button for accepting an instruction to stop sewing by panel operation are displayed.

  Next, it is determined whether or not an instruction to continue sewing or an instruction to stop sewing is input by panel operation (S74). If no instruction is input (S74: NO), the process returns to step S74.

  When an instruction is input (S74: YES), it is determined whether or not an instruction to continue sewing is input in the process of step S74 (S75). When an instruction to stop sewing is input (S75: NO), the approximate color replacement process and the main process are ended. When an instruction to continue sewing is input (S75: YES), the second thread type information selected in step S62 is deleted from the unreceived thread type data table 98 (S76). Next, the process proceeds to step S77. If there is no second thread type information stored in the unreceived thread type data table 98 (S77: NO), the process returns to the main process (see FIG. 16).

  Next, the number of second thread type information stored in the sewing thread type data table 97 is set in the variable M (S53). For example, in the case of FIG. 20, the variable M is set to “3”. Next, the variable N is set to 1 (S54). Next, a thread spool mounting process is executed (S55).

  The thread spool mounting process will be described with reference to FIG. The thread piece mounting process is a process in which the notification device 30 is notified of the position of the thread piece 29 in the order of sewing, and the image is updated by the attached thread piece 29.

  As shown in FIG. 21, first, the second thread type information whose sewing order is Nth in the sewing thread type data table 97 and the notification command information are transmitted to the notification device 30 (S81). In other words, the thread spool 29 used for sewing is searched. The second thread type information and the notification command information transmitted in step S81 are received in step S31 (see FIG. 14) executed by the notification device 30. Then, it is determined that the notification command information has been received (S35: YES), and the light emitting unit 303 emits light for a predetermined time (for example, 3 seconds) and is notified to the user (S36). Thus, the user can recognize the position of the thread spool 29 used for sewing.

  For example, when the variable N is “1”, the second thread type information “405” of the sewing order “1” in the sewing thread type data table 97 (see FIG. 20) and the notification command information are transmitted to the notification device 30. (S81). And as shown in FIG. 15, the alerting | reporting apparatus 30 whose 2nd thread type information is "405" is light-emitted (S36). As a result, the position of the thread spool 291 around which the thread 28 of the thread color “SALMOM-PINK” is wound is notified to the user. Therefore, the user can easily recognize the position of the thread spool 291 necessary for sewing.

  Next, it is determined whether or not the yarn spool 29 is attached to the spool pin 19 (S82). In step S <b> 82, the notification device 30 is detected via the reader / writer 81, so that it is determined whether or not the yarn spool 29 is attached to the spool pin 19. If the thread spool 29 is not attached to the spool pin 19 (S82: NO), the process returns to step S81. That is, the second thread type information and the notification command information are repeatedly transmitted until the thread spool 29 is attached to the spool pin 19 (S81), and notified to the user by the notification device 30 (S36 in FIG. 14). reference).

  When the yarn spool 29 is attached to the spool pin 19 (S82: YES), the yarn type transmission command information is transmitted to the notification device 30 via the reader / writer 81 (S83). The yarn type transmission command information transmitted in step S83 is received by the notification device 30 (S32: YES in FIG. 14), and the first yarn type information is transmitted from the notification device 30 (S38). For example, when the thread spool 291 (see FIG. 15) and the notification device 30 are attached to the spool pin 19, the first thread type information “405” is transmitted (S38).

  After step S83 is executed, it is determined whether or not the first yarn type information transmitted in step S38 (see FIG. 14) of the notification device 30 has been received (S84). If the first thread type information has not been received (S84: NO), the process returns to step S84. When the first reception information is received (S84: YES), it is determined whether or not the first yarn type information received in step S84 matches the second yarn type information transmitted in step S81. (S85). In other words, it is determined whether or not the yarn spool 29 around which the yarn 28 of the same yarn type as the yarn type indicated by the second yarn type information transmitted in step S81 is wound is attached. The case where the first thread type information and the second thread type information do not match is, for example, a case where the thread piece 29 attached by the user is wrong or a case where it is desired to sew with another thread piece 29. When the first thread type information and the second thread type information match (S85: YES), the thread color of the embroidery pattern displayed on the liquid crystal display 15 corresponds to the second thread type information transmitted in step S84. The thread color to be updated is updated.

  For example, when N = 1, the second thread type information “405” in FIG. 20 is transmitted, and when the thread spool 291 (see FIG. 15) is attached to the spool pin 19, the first thread type information “405”. "And the second thread type information" 405 "are determined to match (S85: YES). Then, the display on the liquid crystal display 15 shown in FIG. 10 is updated as shown in FIG. As shown in FIG. 22, the pattern “A” thread color of the embroidery pattern “ABC” is updated to “SALMON-PINK”. After step S86 is executed, the thread spool mounting process is terminated, and step S56 of the main process is performed.

  If the first thread type information and the second thread type information do not match (S85: NO), a message indicating that a different thread spool 29 has been attached to the sewing machine 1 is displayed on the liquid crystal display 15 and is directed to the user. (S87). The message displayed on the liquid crystal display 15 in step S87 is, for example, “A different type of thread spool is attached. Do you want to continue sewing as it is?”. In step S87, for example, a button for accepting an instruction to continue sewing by panel operation and a button for accepting an instruction to replace the thread spool 29 attached to the thread spool 19 by panel operation are displayed. The

  Next, it is determined whether or not an instruction to continue sewing or an instruction to replace the thread spool 29 attached to the spool pin 19 is input by the panel operation (S88). If no instruction is input (S88: NO), the process returns to step S88. If an instruction is input (S88: YES), it is determined in step S88 whether an instruction to continue sewing is input (S89). If it is an instruction to replace the thread spool 29 attached to the spool pin 19, it is determined that an instruction to continue sewing is not input (S89: NO), and the process returns to step S81. As a result, the user can be informed of the position of the yarn spool 29 again (see S36 in FIG. 14).

  When an instruction to continue sewing is input (S89: YES), the thread type data table 95 (see FIG. 8) is referred to, and the thread color indicated by the first thread type information received in step S84 is specified ( S90). In other words, the thread color of the thread 28 wound around the thread spool 29 currently attached to the spool pin 19 is specified. Next, the thread color of the sewing pattern displayed on the liquid crystal display 15 is changed to the thread color specified in step S90 (S91). For example, when N = 2, not the thread spool 296 (see FIG. 13) wound with the thread color “BLUE”, but the thread spool 292 wound with the thread color “GREEN” (see FIG. 13). 13) is attached to the spool pin 19. In this case, as shown in FIG. 23, the color of the pattern “B” of the embroidery pattern “ABC” is changed to “GREEN”.

  Next, the thread spool mounting process is terminated, and the process returns to the main process (see FIG. 16), and it is determined whether or not an instruction to start sewing has been input (S56). The user inputs an instruction to start sewing by pressing the sewing start / stop switch 21. For example, in step S86 or S91 (see FIG. 21), when the user who has confirmed the image displayed on the liquid crystal display 15 wants to change the thread color, the thread is input again by inputting an instruction through the panel operation. The piece mounting process (S55) may be executed.

  If the instruction to start sewing has not been input (S56: NO), the process returns to step S56. When an instruction to start sewing is input (S56: YES), sewing is executed (S57). For example, when N = 1 and the thread spool 291 is mounted on the thread stand 19, the thread color “SAMON-PINK” 28 is used and the embroidery pattern “A” is sewn on the work cloth 100. Is done. Next, it is determined whether or not the variable M and the variable N are equal (S58). In other words, it is determined whether or not all the embroidery patterns have been sewn. If the variable M and the variable N are not equal (S58: NO), the variable N is incremented and incremented by 1 (S59). Next, the process returns to step S55, and the process is repeated. For example, an embroidery pattern “ABC” shown in FIG. 23 is sewn on the work cloth 100. That is, embroidery sewing is completed. In this case, the variable N is “3”, which is equal to the variable M. When the variable N and the variable M are equal (S58: YES), the main process is terminated.

  As described above, the main process in the present embodiment is executed. In the present embodiment, when it is determined in step S34 (see FIG. 14) that the first thread type information and the second thread type information match (S34: YES), the light emitting unit 303 emits light, and the user is notified. Then, it is notified (S36). That is, when the type of the thread 28 wound around the thread spool 29 matches the type of the thread 28 necessary for the sewing machine 1 to perform sewing, the user is notified. Thus, the user can be notified of the position of the thread spool 29 around which the thread 28 necessary for sewing is wound. For this reason, the user can easily confirm the position of the thread spool 29 necessary for sewing. Therefore, user convenience is improved.

Thus, the first yarn type information stored in the notification device 30 can be changed. That is, the first yarn type information can be rewritten according to the type of the yarn 28 wound around the yarn spool 29. Therefore, the notification device 30 can be attached to the yarn spool 29 around which various types of yarns 28 are wound.

  In addition, the notification device 30 can notify the sewing machine 1 that the first thread type information and the second thread type information coincide with each other in step S37 (see FIG. 14). For this reason, the sewing machine 1 can confirm the presence / absence of the thread 28 necessary for sewing by the processing in step S47, step S51 in FIG. 16, step S68 in FIG. Further, the sewing machine 1 can detect that a different thread spool 29 is attached to the spool pin 19 by the process of step S85 in FIG.

  Moreover, the position of the thread spool 29 can be notified to the user by causing the light emitting unit 303 of the notification device 30 to emit light (S36 in FIG. 14). Therefore, the user can easily visually recognize the position of the yarn spool 29.

  The sewing machine 1 transmits the second thread type information in the order corresponding to the sewing order (see S81 in FIG. 21). Then, when the second yarn type information and the first yarn type information match, a notification is given to the user in the process of step S36 executed by the notification device 30 (see FIG. 14). For this reason, the position of the thread spool 29 around which the thread 28 necessary for sewing the embroidery pattern is wound can be notified to the user in the sewing order. The user can sew the embroidery pattern by attaching the thread spools 29 to the sewing machine 1 in the notified order. For this reason, user convenience is improved.

  The case where it is determined in step S51 in FIG. 16 or step S68 in FIG. 18 that the coincidence information has not been received is a case where there is no yarn spool 29 corresponding to the transmitted second yarn type information. is there. In this case, the second thread type information corresponding to the approximate thread color is newly specified (S65 in FIG. 18), and the newly specified second thread type information is transmitted to the notification device 30 (S65 in FIG. 18). ). Then, the notification device 30 of the yarn spool 29 around which the approximate yarn color yarn 28 is wound is notified (S36 in FIG. 14). That is, when there is no thread spool 29 around which the thread 28 used for sewing is wound, the position of the thread spool 29 around which the approximate thread 28 is wound can be notified to the user. For this reason, the user does not have to search for the yarn spool 29 around which the approximate yarn 28 is wound. Therefore, user convenience is improved.

  Further, since the attaching / detaching portion 305 is made of an elastically deformable spring material and is formed in a shape that expands outward in the downward direction, even if the thread spool 29 has a somewhat different inside diameter, the notification is provided. It is possible to attach the device 30 to the thread spool 29. Needless to say, the shape of the attaching / detaching portion 305 and the spring constant of the spring material may be appropriately changed. That is, the notification device 30 can be attached to various yarn spools 29 distributed in the market. Moreover, you may form the attachment / detachment part 305 with a thin leaf spring instead of a wire. Also, an elastically deformable resin material (for example, polyacetal) can be employed instead of a metal spring material. Alternatively, a double-sided adhesive tape may be used as the attachment / detachment portion 305 and affixed to the yarn spool 29.
