Then, by pressing the enter key 80, the displayed (changed) set value is fixed and set.
[0049]
  In the changed parameter detection process of S5, when the parameter is changed and set by the parameter setting process of S4 for the read sewing program, the changed parameter is detected. In this case, the sewing program before change stored without being deleted in the backup RAM 113 is read, and the sewing program before change and the updated sewing program including the changed parameters are compared and changed. Parameters are detected.
[0050]
  In this case, the change parameter detection process can be executed by operating the cursor key 93 and the enter key 80 and designating the icon 17h while the menu screen of FIG. 16 is displayed on the LCD 70.
[0051]
  In the changed parameter display process of S6, the changed parameter detected by the changed parameter detection process of S5 and the parameter before the change corresponding to this parameter are displayed on the LCD 70 in comparison. It is also possible to specify a sewing program other than the sewing program for the read sewing program, detect different parameters of both the sewing programs, and display them in a comparable manner.
[0052]
  In this case, the parameter comparison processing screen of FIG. 20 is displayed on the LCD 70 after the change parameter detection processing is completed. For example, as shown in FIG. 20, in the parameter of parameter number 2 (cutter dimensions), the parameter setting value before change (13.0 mm) and the parameter after changeSet value(15.0mm) is displayed, and in the parameter of parameter number 3 (multiple cutter drop), the parameter setting value (ON) before the change and the parameter after the changeSet value(OFF) is displayed.Note that the cutter dimensions and the multiple cutter drop displayed on the LCD 70 correspond to parameter names.
[0053]
  As shown in FIG. 15, after the change parameter display process in S6, when the writing destination (file) of the sewing program that has been changed and set is designated (S7), the unique information setting process associated with the file (S8) is performed. Eventually, the updated sewing program is written (overwritten or newly newly written) in the designated writing destination (file) (S9) and the process returns. The unique information setting process (S8) can be omitted.
[0054]
  In this case, if the icon 17b is designated by operating the cursor key 93 and the enter key 80 with the menu screen displayed on the LCD 70, the file designation screen shown in FIG. Here, by operating the cursor key 93 and the enter key 80, one file (for example, file 1) in the backup RAM 113 of the programmer 5 as a writing destination can be designated, and the sewing program is written into the designated file. It is.
[0055]
  In the unique information setting process of S8, the screen of FIG. 21B is displayed on the LCD 70 by a predetermined key operation, and when the cursor key 93 and the enter key 80 are operated to specify “Yes”, FIG. ) Is displayed on the LCD 70, and unique information can be input and set by operating the cursor key 93 and the enter key 80. For example, the unique information may be a boring machine name or an operator name.

The backup RAM 113 stores a plurality of sewing programs in which all or some of the plurality of parameters are different. When the parameters are changed and set for the sewing program read from the backup RAM 113, the changed parameters are detected. can do.
[0057]
  Since the detected changed parameter and the parameter before the change corresponding to this parameter can be displayed on the LCD 70 in comparison, the operator can select the sewing program read from the backup RAM 113 or the like when creating the sewing program. It is possible to easily check the changed parameter and the original set value of the changed parameter.
[0058]
  As described above, the plurality of non-volatile files in the backup RAM 113 store a plurality of sewing programs for each sewing machine, and the volatile program storage unit memory of the RAM 112 stores the hole sewing machine to which the programmer 5 is connected. The sewing program read from the sewing machine control device 6 is stored.
[0059]
  As a result, a plurality of hole sewing machines M sewing programs can be stored so as to be identifiable for each sewing machine, and various hole sewing machines M can be machined with or without machining any hole sewing machine M sewing program. Can be used as a sewing program. In other words, in a sewing factory or the like, it is possible to improve versatility as a programmer 5 common to a plurality of hole sewing machines M, thereby simplifying the work of creating and setting a sewing program for a plurality of hole sewing machines M. This is also advantageous in terms of equipment costs.
