Abstract:
1. A contactless connector including a rotation-side light element provided on a rotating body that rotates about a rotation axis, and a fixed-side light element provided on a fixed body, and performing contactless data transmission and reception between the rotation-side light element and the fixed-side light element, comprising: a reflecting body, which reflects light emitted from the rotation-side light element or from the fixed-side light element, on the rotation axis, the reflecting body having a mirror surface on both faces; wherein a light path formed between the rotation-side light element and the fixed-side light element via the reflecting body is substantially orthogonal to the rotation axis, the light path is formed between the rotation-side light element and the fixed-side light element via the reflecting body such that light reflected from the reflecting body is received by the rotation-side light element or by the fixed-side light element, and the reflecting body is of such a thickness that when the reflecting body is positioned between the rotation-side light element and the fixed-side light element due to rotation of the rotating body, the light path between the rotation-side light element and the fixed-side light element is not blocked.
