The first explanatory text and a picture to make the explanation easier to understand are displayed, and then each time a set time elapses, the next page data is displayed in sequence on the display 9 as shown in FIGS. 12(b) to (C). will be displayed.

Similarly, when item number "4" is selected, for example, as shown in FIG. A picture is displayed to make the explanation easier to understand, and then each time a set time elapses, the next page data is displayed in sequence on the display 9 as shown in FIGS. 13(b) to 13(d).

On the other hand, when the sewing machine motor 48 and others are controlled by the control device C1, for example, if the sewing machine motor 48 is not driven to rotate even though the start/stop button 10 is operated to drive the sewing machine motor 48. , the control device C1 determines that the sewing machine motor 48 is locked based on the timing signal from the timing signal generator 31 and the speed signal from the speed sensor 32, and stores data instructing the warning and the warning in the warning data memory. Write data indicating the contents. At this time, it is determined Yes in Sll,
The warning contents of the warning data memory are read out (340),
The display screen is switched, and the display data of the warning contents corresponding to the data indicating the warning contents based on the warning data of the ROM 57 is displayed on the display 9 (S41), and whether or not the warning has been canceled is displayed until the warning is canceled. It is determined (S42
).

For example, as shown in FIG. 14, the content of the warning "Motor is locked!!" and an explanatory text for canceling the warning are displayed. Then, when the operator removes the cause of the motor lock based on the explanation and operates the start/stop button 10 again, the control device C1 retrieves data instructing a warning and data indicating the content of the warning from the warning data memory. The warning is canceled and S4 is cleared.
2 is determined as Yes, and based on the display mode of the display mode memory, the data of the item number counter, display page counter D, and page number counter I, the data that was displayed immediately before displaying the warning content is displayed. 543), 5
12 and subsequent steps are executed.

Furthermore, display examples of other warning contents regarding Sll/S40 to S41 will be explained.

When the sewing machine motor 48 is started by operating the start/stop button 10 with the presser foot 8 raised, the control device C
I writes data instructing the warning state and data indicating the warning content into the warning data memory based on the needle bar position signal from the presser foot switch 35 and the start/stop signal from the start/stop switch 10a. The warning message [The sewing machine cannot be started because the presser foot is raised!] ! " and an explanation for canceling the warning are displayed.

In addition, when a pattern involving cloth feeding is selected with the feed dog lowered and the start/stop button IO is operated, the control device CI receives the feed goat operation signal from the drop feed switch 36 and the start/stop switch. Based on the start/stop signal from 10a, by writing data instructing the warning status and data indicating the warning content into the warning data memory, the warning content ``The feed dog is lowered, so the sewing machine cannot be started.'' No!!” and an explanation for canceling the warning are displayed.

Incidentally, the setting time for making the determination in 338 may be set individually depending on the contents of each item of sewing method data and usage data. The individual setting times may be stored in the memory. In this case, the user can reliably read the displayed explanatory text to the end while fully understanding it.

As explained above, you can take out the instruction manual and search for the desired explanation (but data about patterns, data about how to sew, or general instruction data about how to use the sewing machine are categorized by operating keys 14 to 17). Since the desired data can be selected and the selected data is displayed on the display 9, the operability and work efficiency of the sewing machine are improved.

Furthermore, when you select an item that is made up of multiple divided page data due to its rich explanation content, the consecutive divided page data are automatically displayed in sequence at set times, making it easier to understand the explanation content consistently. As a result, the operability when switching screens is greatly improved, and the degree of understanding of the explanation content is also improved.

In addition, the display 9 displays explanatory text for the desired item and also displays pictures to make the explanation easier to understand, allowing the user to fully understand how to sew and how to use the sewing machine, thereby improving their level of understanding. can be achieved.
