<p>PURPOSE:To freely change the monitoring range from the outside of a container by rotating the first magnet arranged at the outside of the container and finely adjusting an optical equipment in the container via magnets and flexible rods in the container. CONSTITUTION:Magnets 16-19 are arranged vertically in four steps at the outside of a hollow cylinder section 14, and magnets 21-24 are provided inside it. One-side ends of flexible rods 28a-28c are fixed to rotating centers of the magnets 21-23 respectively. The other ends of the flexible rods 28a-28c are fixed to centers of the gears 29a-29c. Therefore, when the magnets 16-18 at the outside of a housing 12 are rotated, the gears 29a-29c are rotated. According to this constitution, when the magnet 19 is rotated, the tip 36a of an image fiber 36 and the tip 37a of a light guide 37 can be swayed in the directions of arrows (a), (b).</p> |
