20090136175 | NON-CONTACT CONNECTOR - A non-contact connector, which has a rotation-side optical element positioned on a rotating body which rotates about a rotation axis, and a fixed-side optical element positioned on a fixed body, and which performs data transmission and reception without contact between the rotation-side optical element and the fixed-side optical element, the non-contact connector further having a reflecting body, which reflects light emitted from the rotation-side optical element or from the fixed-side optical element on the rotation axis; and the reflecting body being a cubic mirror, the outer shape of which is a rectangular parallelepiped, and which is formed by evaporation depositing a thin metal film on one face of one of two rectangular parallelepiped members that are transparent from the visible wavelength range to the infrared wavelength range, and then bonding to the same to the other one of the rectangular parallelepiped members, with the evaporation-deposited film face intervening therebetween. | 05-28-2009 |
