  • the magnetic force generated from the magnet portion 102 penetrates the protection plate 111 and acts on the magnetic tape 10 . Therefore, the fixing device 100 attracts the surface of the magnetic tape 10 on the back plate 11 side, that is, the surface on the opposite side from the reading side of the magnetic tape 10, by the magnetic force generated from the surface of the protection plate 111 facing the magnetic tape 10.
  • damage to the magnet portion 102 and the back plate 11 when the fixing device 100 attracts the magnetic tape 10 can be suppressed.
  • the present disclosure can be used in a magnetic tape fixing device that fixes the middle part of a magnetic tape suspended in an elevator hoistway.
