Abstract
A sewing machine determines a pattern from multiple patterns, as a first pattern. The sewing machine generates a projection image including a first image representing a sewing image of the first pattern in a sewing expected size thereof. The sewing machine projects the generated projection image onto a projection area. The sewing machine sews the first pattern on a workpiece in the sewing expected size based on pattern data for the first pattern.

A sewing machine, comprising:
- a bed;
- a feed unit configured to feed a workpiece in a feeding direction;
- a sewing unit configured to form stiches on the workpiece, the stitches representing a pattern;
- a projector configured to project a projection image onto a projection area on the bed;
- and
- a controller configured to control the feed unit, the sewing unit, and the projector;
- the controller configured to perform:
- determining a pattern from multiple patterns, as a first pattern;
- generating the projection image including a first image representing a sewing image of the first pattern in a sewing expected size thereof, the first image being to be located toward an upstream side in the feeding direction from a position corresponding to a needle drop position located below a needle bar of the sewing unit;
- causing the projector to project the generated projection image onto the projection area;
- and
- controlling the feed unit and the sewing unit to sew the first pattern on the workpiece in the sewing expected size based on pattern data for the first pattern.
