  • Sewing machine
    Patent number: 9290869
    Abstract: A sewing machine includes a needle bar, a needle bar up-and-down movement mechanism, a swinging mechanism, a lower shaft, an outer shuttle, a thread cutting mechanism, a rotation speed adjustment mechanism, and an actuator. The needle bar up-and-down movement mechanism is configured to move the needle bar up and down. The swinging mechanism is configured to swing the needle bar in a left-right direction. The lower shaft is configured to rotate in synchronization with up-down movement of the needle bar. The outer shuttle is configured to rotate along with rotation of the lower shaft. The thread cutting mechanism is configured to cut at least an upper thread. The rotation speed adjustment mechanism is configured to adjust a rotation speed of the outer shuttle. The actuator is a driving source of the thread cutting mechanism and the rotation speed adjustment mechanism.
