Magnetically shielded room
A magnetically shielded room, that is capable of suppressing positional deviation of a measuring tool in an internal space, has an upper shielding body, a side periphery shielding body, and a lower shielding body, which form a magnetically shielded internal space of the magnetically shielded room. A pedestal has a higher rigidity than the lower shielding body, and is located on an under surface of the lower shielding body. First and second supporting members are located on and stand erect from the pedestal. The first and second supporting members penetrate the lower shielding body and extend into the internal space.
1. A magnetically shielded room comprising:
an upper shielding body;
a side periphery shielding body;
a lower shielding body, wherein the upper shielding body, the side periphery shielding body, and the lower shielding body define a magnetically shielded internal space of the magnetically shielded room;
a pedestal having a higher rigidity than the lower shielding body and located on an under surface of the lower shielding body;
a supporting member located on and standing erect from the pedestal, penetrating the lower shielding body, and extending into the internal space; and
a partition member located within the internal space and dividing the internal space into first and second internal spaces, wherein the supporting member penetrates through the partition member.
2. The magnetically shielded room according to claim 1 , wherein
the supporting member has an outer surface, contains a hollow part, and has an opening in the outer surface communicating with the hollow part, and
the magnetically shielded room further includes wirings extending in an upward direction or a downward direction through the hollow part and the opening of the supporting member.
3. The magnetically shielded room according to claim 1 , further including a plurality of the supporting members located on and standing erect from the pedestal, wherein at least one of the supporting members is a rod.
4. The magnetically shielded room according to claim 1 , wherein the magnetically shielded room is movable.
5. The magnetically shielded room according to claim 2 , further including a plurality of the supporting members located on and standing erect from the pedestal, wherein at least one of the supporting members is a rod.
6. A magnetically shielded room comprising:
an upper shielding body;
a side periphery shielding body;
a lower shielding body, wherein the upper shielding body, the side periphery shielding body, and the lower shielding body define a magnetically shielded internal space of the magnetically shielded room;
a pedestal located on an under surface of the lower shielding body;
a supporting member having a lower end penetrating through the lower shielding body and located in and attached to the pedestal, and an upper end standing upright from the pedestal and the lower shielding body and located within the internal space, extending beyond the lower shielding body, toward the upper shielding body; and
a partition member dividing the internal space into first and second internal spaces, wherein the supporting member penetrates through the partition member.
7. The magnetically shielded room according to claim 6 , wherein
the supporting member has an outer surface, contains a hollow part, and has an opening in the outer surface communicating with the hollow part, and
the magnetically shielded room further includes wirings extending through the hollow part and the opening of the supporting member.
8. The magnetically shielded room according to claim 6 , further including two of the supporting members, wherein one of the supporting members is a rod.
9. The magnetically shielded room according to claim 6 , further including a plurality of casters for rolling across a floor and attached to an underside of the pedestal so that the pedestal is between the plurality of casters and the lower shielding body, wherein the magnetically shielded room is movable across the floor via the plurality of casters.
10. A magnetically shielded room comprising:
an upper shielding body;
a side periphery shielding body;
a lower shielding body, wherein the upper shielding body, the side periphery shielding body, and the lower shielding body define a magnetically shielded internal space of the magnetically shielded room;
a pedestal located on an under surface of the lower shielding body; and
a supporting member having a lower end penetrating through the lower shielding body and located in and attached to the pedestal, and an upper end standing upright from the pedestal and the lower shielding body and located within the internal space, extending beyond the lower shielding body, toward the upper shielding body, wherein
the supporting member has an outer surface, contains a hollow part, and has an opening in the outer surface communicating with the hollow part, and
the magnetically shielded room further includes wirings extending through the hollow part and the opening of the supporting member.
11. The magnetically shielded room according to claim 10 , further including a partition member located within the internal space and dividing the internal space into first and second internal spaces.
12. The magnetically shielded room according to claim 11 , further including two of the supporting members, wherein one of the supporting members is a rod.
13. The magnetically shielded room according to claim 11 , further including a plurality of casters for rolling across a floor and attached to an underside of the pedestal so that the pedestal is between the plurality of casters and the lower shielding body, wherein the magnetically shielded room is movable across the floor via the plurality of casters.
