The operation of the present invention configured as described above will be described first with reference to FIGS. 3 (a) and 3 (b).

FIG. 3A is a flowchart showing the basic mode selection operation. As shown in the basic mode selection operation diagram of FIG. 3B, the basic mode is changed every time the M + and M- keys are pressed once. The display changes in the direction of the arrow to switch the display, and one of the four basic modes is selected.

When any one of the four basic modes is selected, if the E key is continuously pressed twice per second (hereinafter referred to as double-click), the mode shifts to each setting mode. Hereinafter, the operations in the four setting modes will be sequentially described.

First, FIG. 4 is a flowchart showing an operation of setting control data.
The operation of individually changing the control data stored in the memory A is performed.

That is, the microcomputer 1 instructs the addition and subtraction of the menu number by the M + and M- keys, and instructs the addition and subtraction of the data by the D + and D- keys via the communication means 3. A menu number and data are reported for each command, and the reported data is displayed on the display 6.

Here, the menu number is a three-digit number (0 to 0).
999) and indicates the type of control data. The data is a 4-digit number (0 to 9999), and the display is “1”.
Menu number 3 digits and data 4 like "06.0016"
It is divided and indicated with a decimal point “.” Between digits.

When the individual setting of the necessary control data is completed as described above, if the E key is double-clicked, the mode returns to the "control data setting" mode of the basic mode.

FIG. 5 is a flowchart showing the operation of setting the identification code.
The operation of changing the identification code stored in the memory A is performed. Here, the identification code is configured by allocating seven digits of data corresponding to each digit that can be displayed as a symbol such as 0-9 and "-" or an alphabetic character for each digit if converted. That is, for example, data of seven consecutive menu numbers 993 to 999 are allocated as data of each digit of the identification number.

The setting operation of the identification code will be described in detail below. First, the data of the menu numbers 993 to 999 are read from the memory of the control device 4, the data is converted into display data, and displayed as a 7-digit identification code. Each time the D + or D- key is pressed, the selected digit is moved left or right to indicate the selected digit to be changed, and the addition / subtraction of the menu number data corresponding to the selected digit is commanded. , A menu number and data are reported, and the reported data is converted and displayed in the blinking digit of the display 6.

As described above, the setting of the identification code according to the present invention is highly versatile, which is indicated by seven-digit alphanumeric characters or symbols. It can be said that distinguishing the states is sufficient. For example, the first two digits (16) may indicate the model of the sewing machine, such as “16-4000”, and the rightmost four digits (4000) may indicate the maximum rotation speed of the sewing machine.

When the above-described setting of the identification number is completed, if the E key is double-clicked, the mode returns to the "identification code setting" mode of the basic mode.

Here, a method and a structure of selecting a bank of the memory B2 which needs to be operated in the setting mode of "data reading" from the control device or "data writing" to the control device will be described with reference to FIGS. Explanation will be made according to b).
