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.

First claim

What is claimed is:

1 . A sewing machine comprising:
a bed extending in a first direction; a feed dog; a needle bar extending in a second direction, the needle bar movable in the second direction, a distal end of the needle bar movable in the first direction with the movement of the needle bar in the second direction, the second direction being orthogonal to the first direction; a projector; and a controller configured to perform:
causing the projector to project a first image toward the bed, the first image representing a first pattern, the first pattern representing a sewing design to be sewn by moving the needle bar in the second direction and moving the distal end of the needle bar in the first direction.

2 . The sewing machine according to claim 1 ,
wherein sewing the first pattern by moving the needle bar in the first direction and the second direction.

3 . The sewing machine according to claim 2 ,
sewing the first pattern along a third direction from below the needle bar, the third direction being orthogonal to the first direction and the second direction.

4 . The sewing machine according to claim 1 ,
wherein the first pattern includes pieces of a predetermined design that are repeatedly arranged in the third direction.

5 . A sewing machine control method comprising:
displaying, by a display of the sewing machine, multiple patterns on a screen of a sewing machine; identifying a pattern from the multiple patterns, as a first pattern; projecting, by a projector of the sewing machine, a first image representing the first pattern; inputting a start instruction by start/stop switch of the sewing machine; sewing, by a feed dog of the sewing machine and a needle bar of the sewing machine, the first pattern.
