Arrangement for signal transmission between rotating and fixed part by light signals, comprises light emitter, which transmits light signals to circular light conductor relative to light emitter

摘要

The arrangement comprises a light emitter (17), which transmits the light signals to a circular light conductor (18) relative to the light emitter. An input or output surface (21) is provided, which is formed at the light conductor guided out from the contour of an annular body (19). An independent claim is also included for a floor dust collecting device for contactless transmission of optical signals.
