The routine of the stitch pattern list display control will be described below with reference to the flowchart of FIG. However, Si (i = 1, 2, 3, ...) In the figure indicates each step, and this routine also includes a part of the pattern selection control routine. It is assumed that the selection of the type of stitch pattern has been completed. When the control is started by the completion of the selection of the stitch pattern type, the pattern group on the first page of the selected stitch pattern is displayed on the display 10 (S1), and then the operation panel 17 is displayed.
It is determined whether or not there is a key input from the display 10 (S2). If there is a key input, it is determined in the next S3 whether or not there is a list display command from the list display command key 18, and if No, S4. In step S4, it is determined whether the key input is from the pattern selection key 11a. When there is a key input from the pattern selection key 11a, the process proceeds from S4 to S5, the flag F indicating the list display mode is reset, and the soft timer TM is set to the predetermined value. Is set for a short time C (this is a short time of 1 to 2 seconds for continuing the display of the same screen), and then the display of the display 10 is switched in S6 to display the selected pattern and The code number of the selected pattern is stored in the memory of the RAM 24. In this case, the stitch pattern display data is read out based on the pattern code number and displayed through the display controller 30, and then the process returns to S2.

Next, when it is determined No in S4, S
In S7, it is determined whether or not there is a key input from the next page key 12b. When the determination result is YES, the flag F is reset and the timer TM is set in S8 as in S5, and then the process proceeds to S9. The display of the pattern group on the next page is displayed on the display 10, and then the process returns to S2. The display of the pattern group is performed by reading the stitch pattern display data of the pattern group corresponding to the page number and supplying the data to the display controller 30. On the other hand, S
If the result of the determination in No. 7 is No, it is determined in S10 whether or not there was a key input from the previous page key 12a. If the result of the determination is Yes, in S11, the flag F is reset and the timer TM is set as in S5. To S12, the pattern group of the previous page is displayed on the display 10 in S12, and then the process returns to S2. Incidentally, S
When the result of the determination in No is 10, it is determined in S13 whether the count value TM of the timer TM is zero, and when the set time of the timer TM has not elapsed, S
The process returns from S13 to S2, and when the set time has elapsed, the control ends. As described above, the display screen of the display 10 is switched by operating the next page key 12b or the previous page key 12a to sequentially display a plurality of pattern groups, and a pattern group including a desired stitch pattern is displayed. Pattern selection key 11 of the desired pattern displayed on the display 10
By pressing a, the desired stitch pattern can be selected.

By the way, when it is desired to list all the stitch patterns of the selected type during the pattern selection as described above or before the pattern selection is started, the list display command key 18
When is pressed, it is determined as Yes in S3 and S14
Then, the flag F indicating the list display mode is set in S14, then it is determined in S17 whether there is a next page, that is, whether it is not the last page. If the last page is not being displayed, the process proceeds to S18. Then, the pattern group on the next page is displayed, then the timer TM is set to a predetermined short time C (S19), and then the process returns to S2, but since there is no key input in this case, the process proceeds from S2 to S15 and the flag F is set. Is determined. In this case, since the flag F is set, it is determined to be Yes and the process proceeds to S16, where S1
At 6 it is determined whether the count value of the timer TM is zero, and if the predetermined short time has not elapsed, it is determined as No and S
Returning to step 2, S2, S15, and S16 are repeated, the display content of the display 10 is held for a predetermined short time, and when the predetermined short time elapses, the process proceeds from S16 to S17, and S17 and the subsequent steps are repeated as described above. As a result, the pattern group on the next page is sequentially displayed for a predetermined short period of time, and the pages (screens) are sequentially switched to the end page side. After the display of the pattern group on the last page is completed, it is determined No in S17 and the process proceeds to S20. Then, in S20, the group of patterns on the first page is displayed, and then the timer TM is set to a predetermined short time C (S
21) and returns to S2. When the list display command switch 18 is pressed while the pattern group on the last page is displayed, S3, S
After S14 and S17, the process proceeds to S20, the pattern group of the first page is switched to the display, and then the second page and the third page are displayed in this order. In addition, while displaying the list of the stitch patterns,
It is possible to select a desired pattern by pressing the pattern selection key 11a where the desired pattern is displayed.

As described above, the list display command switch 18
By operating, all the stitch patterns of the specified type can be sequentially displayed on the display 10 in units of pattern groups. Therefore, what kind of pattern is present and which side of the desired pattern is stored in the storage order. Since it is possible to easily know whether or not there is a pattern, it becomes possible to easily, efficiently and accurately perform pattern selection. As a modification of the above embodiment,
When the list display command switch 18 is pressed, it may be configured to immediately switch to the display of the pattern group on the first page, or may be configured to stop the display after displaying all the patterns once. May be. Incidentally, when the keys 19a to 19c are operated during execution of this control, the control is terminated.
