Abstract
The present invention is a contactless connector that comprises a rotation-side light element that is provided on a rotating body of rotating about an axis of rotation and a fixed-side light element that is provided on a fixed body, data transmission and reception being contactlessly performed between the rotation-side light element and the fixed-side light element. The rotation-side light element and the fixed-side light element are provided on a disk face of the rotating body and a disk face of the fixed body respectively, which are substantially orthogonal to the axis of rotation, and provided oblique with respect to the respective disk faces to form a light path that is oblique with respect to the axis of rotation. The contactless connector further comprises an aperture that allows light emitted from the rotation-side light element or the fixed-side light element to pass, between the rotating body and the fixed body.
