Sewing machine

Abstract

An object of the present invention is to provide a sewing machine that naturally enables performing normal sewing work, and that enables skipping a stitch during the sewing work, and furthermore, another object is to provide a sewing machine that enables causing a latching portion and an engaging device of the needle bar to be accurately engaged and disengaged when skipping the stitch during the sewing work. An operating member return spring is provided between the operating member and the frame; and the operating member return spring is formed such that, in a process that upon supplying power to the solenoid the latching portion is being driven from the engaging position to the retreated position, a spring force of the operating member return spring is not, or only weakly exerted on the operating member while the latching portion is located between the engaging position and the vicinity of a departing point where the latching portion starts to be disengaged, and that the spring force is relatively strongly exerted on the operating member while the latching portion is located between the vicinity of the departing point and the retreated position, so that resilient force is stored in the operating member return spring with the movement of the operating member.
