  • Publication number: 20240085658
    Abstract: A lens barrel 100 includes a fifth lens group unit 25, a focus ring 31, an internal gear 31b, a pinion gear 41, a detection magnet 43, and a GMR sensor 44. The internal gear 31b rotates integrally with the focus ring 31 and has a plurality of gear portions 31c. The pinion gear 41 is provided on the inner peripheral surface side of the focus ring 31 and has a gear portion 41a that mates with the gear portion 31c of the internal gear 31b, and a guide shaft 42 that is inserted through the center of the gear portion 41a. The guide shaft 42 is inserted through the detection magnet 43, and the detection magnet 43 rotates integrally with the gear portion 41a and has a magnetized surface 43b on which different magnetic poles are alternately magnetized. The GMR sensor 44 is fixed to a member separate from the detection magnet 43, is provided at a position adjacent to the detection magnet 43, and detects the rotation of the detection magnet 43 that rotates along with the pinion gear 41.

  • Patent number: 11921365
    Abstract: An isolator includes a first core, a second core, a nonreciprocal member, and a magnetic body. The first core and the second core extend in a first direction and are positioned side by side with a cladding therebetween in a second direction that intersects the first direction. The nonreciprocal member is in contact with at least a part of the second core while being positioned side by side with the second core in the second direction. In a magnetic field generated by the magnetic body in a portion where the nonreciprocal member is positioned, a component in a third direction perpendicular to the first direction and the second direction is greater than any component other than the component in the third direction.
