Claims

[Claim for Utility Model Registration] The needle bar, which acts while the sewing machine is stopped, has a needle with an upper thread fixed to its lower end, and the needle bar is stopped at a specific position where the needle is removed from the material to be sewn on the top of the bed. a fixed position stopping device; a thread cutting device that operates in conjunction with the action of the fixed position stopping device and cuts the needle thread connected to the needle and the workpiece below the bed; and a thread cutting device that faces the upper surface of the bed and is movable up and down. A presser foot that is supported on the machine frame and has an elastic force that always points toward the top of the bed, and a presser foot that uses its elastic force to press against the top of the bed or separate it upward from the top of the bed against the elastic force. It has a presser foot lifting mechanism that can be manually operated, and a switching lever that is supported on the machine frame so that it can be moved manually and always moves, and stops at a fixed position by receiving elastic force in one direction. In a sewing machine equipped with a one-needle stop device that acts to interrupt the interlock between one needle and the main shaft in relation to movement in a reverse direction against the 1. A thread tension device comprising a pair of thread tension discs disposed facing each other so as to be movable along a fixed straight line, and an elastic body having an elastic force that presses both thread tension discs against each other; an interlocking body that is movable to an action position that releases the acting force of the sleeve body from the thread tension disc and a non-action position that allows the action of the elastic body to the thread tension disc; The machine frame can be manually moved between a first position within the movement path of the switching lever and a second position further away from the movement path of the switching lever. and an operation arranged in relation to the interlocking body and the switching lever so as to move the interlocking body to the operating position in the first half of the movement and move the interlocking body to the operating position in the second half of the movement. A thread loosening device for a sewing machine, comprising: a body, and an elastic body having an elastic force that always presses an operating body to maintain it in a first position.
