Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a setting method for repeatedly embroidering the same pattern.

[0002]

2. Description of the Related Art Conventionally, the setting of the repetitive sewing is performed by setting the number of times of repetitively sewing the target embroidery pattern in the X direction, the number of times of repetitive sewing in the Y direction, and the intervals between the embroidery patterns in the X and Y directions. Enter manually with the above key operation. The number of repetitions in the X and Y directions is the numerical value of the embroidery range unique to the sewing machine (for example, a rectangular range of 400 mm in the X direction and 500 mm in the Y direction), the numerical value of the embroidery range in the X and Y directions of the embroidery pattern, and the embroidery pattern. It is roughly calculated from the numerical value of the interval between the X and Y directions.

[0003]

In the above-described repetitive sewing setting, if the calculation of the number of repetitions is too rough, or if there is a mistake in the calculation, an embroidery pattern that does not fit within the embroidery range appears. Therefore, there is a sewing machine having a function of visually displaying whether or not each embroidery pattern is well within the embroidery range on a display of an operation panel. But,
If such a function is not provided, it is difficult to determine whether or not each embroidery pattern falls within the embroidery possible range without actually sewing the embroidery pattern. Therefore, it is inconvenient to sew as many embroidery patterns as possible within the embroidery range. An object of the present invention is to solve the above-described problem. For example, when it is desired to store as many embroidery patterns as possible within the embroidery possible range, the user only needs to input the interval in the X and Y directions between adjacent embroidery patterns. The number of embroidery patterns automatically calculated in step (1) can be confirmed prior to the sewing operation.

[0004]

SUMMARY OF THE INVENTION According to the present invention, there is provided an embroidery pattern setting method for an embroidery pattern, wherein the embroidery pattern is to be repeatedly sewn. , And input the respective intervals in the X and Y directions between adjacent embroidery patterns. The input interval data, the embroidery range data in the X and Y directions of the embroidery patterns, and the X and Y Based on the embroidery range data relating to the direction, the number of times of repeated embroidery in the X and Y directions within the embroidery range is automatically calculated. Therefore, when it is desired to store as many embroidery patterns as possible within the embroidery range, the number of embroidery patterns that can be repeated within the embroidery range can be easily determined by simply entering the interval data between the embroidery patterns as described above. And their arrangement can be confirmed prior to the sewing operation.

Preferably, the embroidery start position is automatically determined in accordance with the arrangement of the embroidery patterns within the embroidery possible range. More preferably, the number of times of repetitive embroidery in the X and Y directions is displayed on a display as described in claim 3.
