Abstract
A sewing machine includes a bed, a projector configured to project an image toward the bed onto at least a guarantee area, a storage medium, and a controller. The controller controls the projector to project the image toward the bed onto a maximum area. The controller determines, based on a position of the image projected onto the maximum area, first world coordinates representing, in a real space coordinate system, a rectangular area contained in the maximum area. The controller determines, based on the first world coordinates, second world coordinates representing, in the real space coordinate system, a target area containing at least the guarantee area. The controller stores the second world coordinates in the storage medium.
