Abstract
Yarn feeders are arranged such that feeder case portions are slidably engaged with a knitting yarn guide rail disposed on an upper portion of needle beds, and can be selectively brought by a bringing device. Each of the feeder cases is provided with a switching mechanism for switching a yarn feeding port to a feeding position and a waiting position by swinging the port. The switching mechanism is operated at a time during which a yarn feeder selected by the bringing device is brought from a stop state in order to feed yarn. The yarn feeding port is switched from the waiting position to the feeding position, a swinging direction of the yarn feeding port to the waiting position, after it feeds yarn, is set, and the yarn feeding port can be switched from the feeding position to the waiting position in association with a selection cancel operation of the bringing device after the yarn is fed.
