The sewing machine includes a projector, a processor, and a memory storing computer-readable instructions that cause the processor to perform processes. The processes include generating processing of generating a first image including a first object representing a first sewing pattern and generating a second image including a second object representing a second sewing pattern. The first sewing pattern is at least a part of the sewing pattern and is a state in which the sewing is incomplete. The second sewing pattern is a part of the sewing pattern and is a state in which the sewing has progressed further than the first sewing pattern. The processes include projection processing of, after causing the projector to project the first image, switching the projected first image, during the sewing, to the second image, and causing the projector to project the second image.

A sewing machine includes a bed portion, a conveyance portion, a sewing portion, an image capture portion, a projector, a processor, and a memory. The conveyance portion is configured to convey a sewing object placed on the bed portion. The memory is configured to store marker information and computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include causing the image capture portion to perform the image capture at a predetermined timing, during a conveyance period, identifying the marker in a captured image, using the marker information stored in the memory, identifying a projection position corresponding to the identified marker, when the marker is identified, and causing the projector to project the projection image indicating the identified projection position, while following a movement of the marker on the sewing object being conveyed.

A sewing machine includes a sewing portion, a movement portion, a processor, and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes.

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.

A non-transitory computer-readable medium stores computer-readable instructions for sewing data generation. The computer-readable instructions are executed by a processor provided in a sewing data generation device. When executed by the processor in the sewing data generation device, the computer-readable instructions instruct the processor to perform following processes. First, the processor acquires a pattern. And, the processor divides the acquired pattern into a first pattern and a second pattern. The second pattern includes an overlapping portion. The overlapping portion in the second pattern partially overlaps with the first pattern. The processor generates sewing data to sew each of the first pattern and the second pattern on a sewing object. And, the processor generates processing data to process, in full size, a processing pattern. The processing pattern is obtained by excluding the overlapping portion from the second pattern, on a sheet-like processing object different from the sewing object.

A computer-readable medium stores instructions for a processor in a sewing data generation device. When the instructions are executed, the processor acquires pattern data of embroidery pattern including partial patterns using different thread. If first common data indicating the same thread is included in first data of a first embroidery pattern and second data of a second embroidery pattern, the processor sets a sewing order in the first data, while causing the partial pattern using the thread of the first common data to be the partial pattern that is last in the sewing order in the first embroidery pattern, and sets a sewing order in the second data, while causing the partial pattern using the thread of the first common data to be the partial pattern that is first in the sewing order in the second embroidery pattern that is the embroidery pattern subsequently to the first embroidery pattern.
