a yarn feeding port associated with said feeder case, said yarn feeding port capable of being positioned in a yarn feeding position and first and second waiting positions on opposite sides of the yarn feeding position, and said yarn feeding port capable of being swung between the yarn feeding position and the first and second waiting positions via operation of a switching mechanism,
wherein the switching mechanism is constructed and arranged to
(i) swing said yarn feeding port from the first waiting position to the yarn feeding position at a time during which said feeder case starts to be moved, via operation of the bringing device, from a stop state toward the needle bed, and set a swinging direction such that said yarn feeding port is swung from the yarn feeding position to the second waiting position after yarn is fed from said yarn feeding port, and
