Abstract

A magnetically shielded room reducing pressure felt by a person inside includes an upper shielding body, a side periphery shielding body, and a lower shielding body, all of which define a magnetically shielded inner space. A magnifying lens is located in the upper shielding body. The magnifying lens can magnify and project an incident image from outside to a range of one inner side surface of the magnetically shielded room. so that the range should be 50% or more of the area of the one inner side surface. The range includes most of the area above a line of sight of a person in the magnetically shielded room. The magnifying lens is provided at a position closer to the one inner side surface as a projection target of the lens than the other inner side surface as a non-projection target facing the one inner side surface as the projection target.

First claim

The invention claimed is:

1. A magnetically shielded room comprising:
an upper shielding body, a side periphery shielding body, and a lower shielding body, together defining a magnetically shielded inner space; and
a magnifying lens located in at least one of the upper shielding body and the lower shielding body, wherein the magnifying lens magnifies and transmits an image projected onto the magnifying lens from outside the magnetically shielded room to one of
(a) at least a first inner side surface of the magnetically shielded room, and
(b) a transparent or translucent film or sheet which extends vertically or obliquely up and down in the magnetically shielded room.

2. The magnetically shielded room according to claim 1 , wherein the magnifying lens is located at a position closer to the first inner side surface, as a projection target of the lens, than a second inner side surface, which is a non-projection target facing the first inner side surface.

3. The magnetically shielded room according to claim 1 , wherein a respective magnifying lens is located in a respective position corresponding to each upper side surface of a plurality of inner side surfaces of the magnetically shielded room.

4. The magnetically shielded room according to claim 1 , wherein an image outside of the magnetically shielded room is projected onto and transmitted by the magnifying lens.

5. The magnetically shielded room according to claim 1 , wherein the magnifying lens includes a right-eye magnifying lens that projects a right-eye image and a left-eye magnifying lens that projects a left-eye image.

6. The magnetically shielded room according to claim 1 , wherein at least a projection range of the inner side surface that is a projection target of the magnifying lens is covered with a material for displaying a projected image.

7. The magnetically shielded room according to claim 1 , wherein the magnetically shielded room is movable.

8. A magnetically shielded room comprising:
an upper shielding body, a side periphery shielding body, and a lower shielding body; and
a magnifying lens located in the upper shielding body, wherein the magnifying lens magnifies and transmits an image projected onto the magnifying lens from outside the magnetically shielded room over all of inner side surfaces of the magnetically shielded room.

9. The magnetically shielded room according to claim 8 , wherein an image outside of the magnetically shielded room is projected onto and transmitted by the magnifying lens.

10. The magnetically shielded room according to claim 8 , wherein the magnifying lens includes a right-eye magnifying lens that projects a right-eye image and a left-eye magnifying lens that projects a left-eye image.

11. The magnetically shielded room according to claim 8 , wherein at least a projection range of the inner side surface that is a projection target of the magnifying lens is covered with a material for displaying a projected image.

12. The magnetically shielded room according to claim 8 , wherein the magnetically shielded room is movable.
