Abstract
A sewing machine including a needle bar to which a sewing needle conveying a sewing thread is secured, a main shaft to which the needle bar is connected, a loop catcher which cooperates with the sewing needle to catch a loop of the sewing thread conveyed by the needle, a catcher shaft to which the loop catcher is connected, a drive motor which drives at least one of the needle bar and the loop catcher by rotating a corresponding one of the main shaft and the catcher shaft, a first sensor which detects a first reference rotation position of at least one of the main shaft and the catcher shaft and generates a first detection signal indicating that the one shaft is taking the first reference rotation position, a second sensor which detects a second reference rotation position of the drive motor and generates a second detection signal indicating that the drive motor is taking the second reference rotation position, and an indicating device which indicates, based on the first detection signal, that the one of the main shaft and the catcher shaft is taking the first reference rotation position and indicates, based on the second detection signal, that the drive motor is taking the second reference rotation position.
