Abstract

PURPOSE:To reduce power consumption and heat generation, by arranging a pair of iron cores, around which an exciting coil is wound, between a permanent magnet and an iron piece, so as to form a magnetic circuit where one is attracted to the permanent magnet while the other touches the iron piece. CONSTITUTION:An H-shaped permanent magnet 11 and an iron core 12 are shielded magnetically through a nonmagnetic spacer 13 and coupled mutually. A hinge 14 on both sides of the spacer 13 supports them at a bearing rotatably to an arrow direction. Exciting coils 18, 19 are wound around a pair of bar iron cores 17, 18, and arranged between the permanent magnet 11 and the iron core 12 as drives 15, 16 for setting and resetting. The iron piece 12 touches or comes close when the permanent magnet 11 is attracted to either iron core 17 or 18. The iron core 17 or 18 is arranged to form a magnetic circuit. This enables driving with a use of permanent magnet flux and miniaturizing with less power consumption and heat generation of the exciting coils.
