Title | SHIELD BOX FOR BIOMAGNETIC MEASUREMENT OF SMALL ANIMAL AND BIOMAGNETIC MEASUREMENT APPARATUS FOR SMALL ANIMAL |
Abstract |
PROBLEM TO BE SOLVED: To simplify a constitution by dispensing with a double door. SOLUTION: This shield box for biomagnetic measurements consists of an inner container 1 that is made from a magnetic/radio shielding material and can accommodate a small animal such as a mouse, and an outer container housing the inner container 1 in its inside and made from the magnetic/radio shielding material. The inner container 1 and the outer container 2 are concentrically disposed and, when an outer container cylindrical body 2b alone of the outer container 2 is rotated, an inner container opening 1a and an outer container opening 2a are located in a superposed position at one time and non-superposed position at another time. When the inner container opening 1a and the outer container opening 2a are located in the superposed position, an access from the outside to the inside of the inner container 1 becomes possible. When the inner container opening 1a and the outer container opening 2a are located in the non-superposed position, the outside noise is shielded. Non provision of the double door can simplify the constitution. |
