Patent ID: 7885495

Claim:
A non-contact connector, comprising: a rotating body; a fixed body; a rotating-side light-emitting element and a rotating-side light-receiving element installed on the rotating body respectfully; and a fixed-side light-emitting element and a fixed-side light-receiving element installed on the fixed body respectfully, wherein with a first focal point of a light-emitting side of a three-dimensional elliptical reflecting body being on a side of the rotating body and a second focal point of a light-receiving side being on a side of the fixed body, a condensing action from the first focal point to the second focal point is used to configure an optical path from the rotating-side light-emitting element set at the first focal point, via a fixed-side elliptical partial mirror in which a portion of the three-dimensional elliptical reflecting body is used as a mirror face, to the fixed-side light-receiving element set at the second focal point, and to configure a simultaneous bidirectional single-channel optical path from the fixed-side light-emitting element set at the first focal point of the three-dimensional elliptical reflecting body, via a rotating-side elliptical partial mirror in which a portion of the three-dimensional elliptical reflecting body is used as a mirror face, to the rotating-side light-receiving element set at the second focal point; and non-contact multi-channel optical communication is performed simultaneously and bidirectionally by configuring a plurality of single-channel optical paths, simultaneously and bidirectionally, between the rotating body and fixed body.
