Abstract
A circular stitching device is attachable to a bed of a sewing machine. The circular stitching device is configured to anchor a sewing workpiece in a rotatable manner at an anchor position that is apart from a needle drop position of a sewing needle by a distance corresponding to a size of a circular stitching pattern to be formed on the sewing workpiece. A projector is configured to project a projection image toward the bed. A controller is configured to perform controlling the projector to project the projection image representing at least part of the circular stitching pattern of the size to be formed on the sewing workpiece. The circular stitching pattern is formed by continuously arranging a unit pattern in a circular shape.
Claims20
A sewing machine comprising:
- a bed to which a circular stitching device is attachable, the circular stitching device configured to anchor a sewing workpiece in a rotatable manner at an anchor position that is apart from a needle drop position of a sewing needle by a distance corresponding to a size of a circular stitching pattern to be formed on the sewing workpiece;
- a projector configured to project a projection image toward the bed;
- and
- a controller configured to perform:
- controlling the projector to project the projection image representing at least part of the circular stitching pattern of the size to be formed on the sewing workpiece, the circular stitching pattern being formed by continuously arranging a unit pattern in a circular shape.
A non-transitory computer-readable storage medium storing a set of program instructions for a sewing machine comprising a bed to which a circular stitching device is attachable, a projector configured to project a projection image toward the bed, and a controller, the set of program instructions, when executed by the controller, causing the sewing machine to perform:
- determining a size of a circular stitching pattern, the circular stitching device being configured to anchor a sewing workpiece in a rotatable manner at an anchor position that is apart from a needle drop position of a sewing needle by a distance corresponding to the size of the circular stitching pattern to be formed on the sewing workpiece;
- identifying a unit pattern that forms the circular stitching pattern;
- generating the projection image representing at least part of the circular stitching pattern having the determined size, the circular stitching pattern being formed by continuously arranging the identified unit pattern in a circular shape;
- and
- controlling the projector to project the projection image.
