PURPOSE:To permit the equally spaced magnets throughout the circumferential part of a flexible PC plate for miniaturizing yokes by drawing out the cable part of the flexible PC plate from gap between the yokes. CONSTITUTION:The base plate 25 of a flexible PC plate 24 made of a soft synthetic resin is attached to the inside of yokes 22 through an insulating plate 23. In the base plate 25, a through hole 26 through which a needle 17 is passed is formed, and also through holes 27 through which cores 21 are passed are formed around the through hole 26. The printed wiring 29 of the base plate 25, by which the coil 28 of a magnet 20 is electrically connected, is also extended to the cable part 30 which is drawn out from the gap between the yokes 22 and wound around the periphery. |
