Knitting member selecting actuator of knitting machine

A knitting member selection actuator of a knitting machine comprising at least one controlled attraction region in which a pair of coil magnetic poles, each having an attraction surface at a front end thereof, are arranged in parallel to sandwich a permanent magnet therebetween and an uncontrolled attraction regions which are placed at lateral sides of the controlled attraction region and in which a pair of yokes, each having an attraction surface at a front end thereof, are arranged in parallel to sandwich a permanent magnet therebetween and no coil magnetic pole is included in their magnetic circuit, wherein the pair of coil magnetic poles of the controlled attraction region are energized to cancel out magnetic flux of the attraction surfaces generated by the permanent magnet, so as to release a knitting member, such as a selector, from the attraction surfaces, so as to select the knitting member, and wherein there is provided between the pair of yokes magnetic property means for making a magnetic reluctance between the confronting yokes of the uncontrolled attraction region larger than a magnetic reluctance between the yokes of the uncontrolled attraction region and the knitting member attracted to the attraction surfaces and also smaller than a magnetic reluctance between the yokes of the uncontrolled attraction region and the attraction surfaces of the adjacent controlled attraction region.
