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.
