Abstract
An optical connection device includes a light source section configured to emit light, a light guide section configured to guide the light emitted from the light source section and including an emitting section configured to emit the guided light to the outside, and a light receiving section configured to receive the light emitted from the emitting section. At least one of the light source section and the light receiving section turns around a turning axis. Therefore, a transmission distance of the light from the light source section to the light receiving section changes.
